PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY OF WASHINGTON VOL. 59 FEBRUARY 1957 NO. 1 THE THROAT BOT FLY: GASTEROPHILUS NASALIS OR VETERINUS? (DieTERA, GASTEROPHILIDAE ) Curtis W. Sasrosky, Entomology Research Branch, U. S, Department of Agriculture, Washington, D. C. Adoption of the name Gasterophilus veterinus for the throat bot fly of horses in the latest taxonomic study of the Gasterophilidae, by Zumpt and Paterson (1953), has again raised the question of the proper scientific name for that species, long known to North American entomologists as Gasterophilus nasalis (l.). Authors who reject nasalis for a horse bot have applied the name instead to a deer nose bot called Cephenemyia trompe (Modeer) by other authors. In Opinion 106 of the International Commission on Zoological Nomenclature (1929), Cephenemyia was placed on the Official List of Generic Names with Oestrus trompe Fabricius as the type species (Fabricius actually credited the species to Modeer!). In the body of the Opinion, although not in the Summary, trompe is said to be a synonym of Oestrus nasalis Linnaeus. However, that is a zoological conclusion, and its acceptance or rejection is not affected by the Commission’s action relative to the generic name and its type species. After reviewing the evidence and the conflicting opinions, it is my conclusion that the proper scientific name of the throat bot fly should be Gasterophilus nasalis (u.)1 for three major reasons discussed below. (1) A Mixed Series and the First Reviser Rule Early descriptions of bot and warble flies (Oestridae in the old and very broad sense) soon involve one in uncertainty and confusion. Descriptions of adults, which are often brief and generalized, are combined with various statements of larval habitat, and it is difficult to be positive about what an author described or included. In four important publications of Linnaeus, species are described as follows in the genus Oestrus: 1746. Fauna Suecica, ed. 1, pp. 306-307: Six species described; not named 1pr. F. Zumpt, of the South African Institute for Medical Research at Johannes- burg, South Africa, has kindly permitted me to state that he has read the manu- script and agrees fully with the conclusions, at which he had arrived independently subsequent to his 1953 publication. I am also indebted to Dr. F. van Emden, of the Commonwealth Institute of Entomology at London, for suggestions and review of the manuscript. 2 PROC. ENT. SOC. WASH., VOL. 59, NO. 1, FEBRUARY, 1957 binominally, but from comparison of data and references with the next three works, it is clear that the species are described in the following order: bovis, tarandi, nasalis, ovis, haemorrhoidalis, and a_ sixth species not subsequently referred to Oestrus. 1758. Systema Naturae, ed. 10, pp. 584-585: Five species, in the order bovis, tarandi, nasalis, haemorrhoidalis, ovis. 1761. Fauna Sueciea, ed. 2, pp. 428-430: Five species, in the same order as in 1758. 1767. Systema Naturae, ed. 12, vol. 1, part 2, pp. 969-970: Five species in the same order as in 1758. By the order of listing of species, which is consistent throughout for bovis, tarandi, and nasalis, and by the references, one could con- clude that nasalis is the same throughout. If one considers only the 1746 description and associated information, it seems certain that the deer nose bot was described. But the starting point for zoological names is the tenth edition of the Systema Naturae in 1758. Abbre- viated though it is, the diagnosis in the latter is markedly different from that in 1746, plus the fact that Linnaeus introduced the state- ment ‘‘ Habitat in Equorum fauce, per nares intrans.’’ The diagnosis has been interpreted by some able specialists (Aldrich 1926; van Emden in litt.) as applying perfectly to a species of Gasterophilus, and by other able specialists (Railliet 1918; Rodhain and Bequaert 1920) as applying perfectly to a species of Cephenemyia. Its perfec- tion is clearly open to difference of opinion. It appears to me to agree most nearly with the usual appearance of the Gasterophilus which has been called nasalis. The habitat statement quoted above has long been dismissed as an erroneous observation by primitive peoples, a lapsus, or the erroneous association by Linnaeus of the habitat of still another —and non-Scandinavian — species, Rhinoestrus purpureus (Brauer). However, in view of the fact that throat bot larvae may in their early Stages attach to the throat or pharynx, sometimes in numbers, the habitat statement may represent a keen observation that was far ahead of its time and not appreciated. If therefore one considers only the diagnosis and habitat informa- tion of 1758, it is possible to conclude, from one point of view at least, that Linnaeus was indeed dealing with the horse bot that we know as Gasterophilus nasalis. However, he also cited species No. 1026 of the Fauna Suecica (1st edition), which is admittedly the deer nose bot. I believe that in all such cases one must consider all the informa- tion present,” including descriptive material, habitat, and references, “If this is not done, some peculiar situations will arise. For example, the original diagnosis of adult Oestrus bovis L. (now Hypoderma bovis, the northern cattle grub) is unmistakably that of the horse bot fly, Gasterophilus intestinalis (DeGeer), associated in error with the larvae living in the backs of cattle. DeGeer recognized the confusion, restricted bovis to the cattle pest, and proposed intesti- nalis for the horse bot fly. I doubt that anyone would insist on calling the horse bot fly Gasterophilus bovis on the basis of only the diagnosis part of the original publication. PROG. ENT. SOC. WASH., VOL. 59, NO. 1, FEBRUARY, 1957 vo as representing the total species concept of the author, no matter how confused it may be by modern standards. Accordingly, I consider Oestrus nasalis Li. (1758) to have been based upon a mixture of species. It then becomes necessary to determine the first reviser, i.e., the first author who recognized that a mixture existed and who clearly restricted the name nasalis to one of its component parts. Linnaeus himself appears merely to have continued his confusion of 1758 in his later works. As far as I ean find, the first author who clearly recognized and resolved the confusion was Modeer (1786), who proposed Oestrus trompe for the deer nose bot, and restricted Oestrus nasalis to the horse bot. Under trompe he pointed out that Linnaeus described the species on deer, though not perfectly, in the first edition of the Fauna Suecica. However, wrote Modeer (pp. 134-5), ‘SA ereater error has occurred in the second edition of the same book, for in that there is an entirely different and quite separate description bearing on an entirely different little creature, entered under the name of nasalis (whose larva lives in the horse’s pharynx).’’? After noting the elimination of accompanying citations from Oestrus nasalis in the fifth edition of the Systema Naturae, Modeer stated that ‘‘From all this it can certainly be concluded that Oestrus trompe is far differ- ent from the nasalis cited in the more recent Fauna Suecica and the above-mentioned Systema...’’ (p. 135). Later, under nasalis, Modeer wrote that ‘‘There is no other author who has described this nose- sting fly [Nosstyng-fluga, i.e. Oestrus nasalis] except von Linné’’ (p. 146) {Translations from Swedish by Miss Ruth Ericson]. Modeer’s work made a clear-cut distinction between trompe and nasalis, After his work, the name trompe was widely recognized by the great dipterists of the time (e.g., Fabricius, Fallén, Meigen, Zetter- stedt, etc.) as applying to a deer nose bot, and nasalis to a horse bot (either as the name of choice or as a synonym of veterinus ). (2) Substitute Name In 1797 Bracy Clark definitely accepted nasalis as applying to the throat bot fly, but renamed it veterinus only because he regarded the name nasalis as inappropriate (‘‘T have given it the name veterinus, because beasts of burden are particularly subject to it, in preference to the erroneous one of nasalis,’’ p. 313). Veterinus, which has been used for the throat bot fly by those authors who regard nasalis as a deer nose bot, is thus really only a substitute name for nasalis and neither a separate proposal nor a restriction. It is, however, an invalid substitute name, because zoological names are not to be rejected be- cause of inappropriateness (International Rules of Zoological Nomen- clature, Article 32); hence the proper specific name is nasalis, with veterinus as an objective synonym. 4 PROC. ENT. SOC. WASH., VOL. 59, NO. 1, FEBRUARY, 1957 (3) Usage Although a few authors, chiefly taxonomists, have used nasalis L. for the deer nose bot and veterinus Clark for the throat bot fly of horses, predominant usage since Modeer (1786) has nasalis L. as the throat bot fly and trompe Modeer as the deer nose bot. As a purely practical approach, there will be less inconvenience and more contribu- tion to stability by maintaining that predominant usage. Otherwise, the specific names of two important economic species would have to be changed, including the transfer of the name nasalis from one species to another. We are not always so fortunate to find that usage and technical priority yield the same answer. LITERATURE CITED (other than references in text) Aldrich, J. M., 1926.

WinuiAmMs’ During June and July, 1955, the junior author conducted light- trap and recovery-cage studies of the Heleidae in each of the several parishes of Bermuda, and made observations on their breeding habits, which he will report on separately. Two pairs of recovery cages were placed for weekly periods in each of 15 areas, and a mosquito lght trap was operated for a week in each of 7 of the areas and for 4 days at the Biological Station. In this study 13 species of Heleidae, rep- resenting 4 genera, were taken, of which 5 species are new to science. In the taxonomic descriptions the following terms should be defined : ‘* Antennal ratio’? (AR) is the value obtained by dividing the com- bined lengths of the five elongated distal segments by the combined leneths of the preceding eight, or XI-XV over III-X (in Pterobosca the ratio is X-X'V over III-IX). ‘‘Tarsal ratio (TR) is the value ob- tained by dividing the length of the hind basitarsus by the length of the second hind tarsomere. Wing length is measured exactly from the basal arculus to the wing tip. The Tillyard modification of the Com- stock-Needham system of wing venation is used whereby the branches of the anterior fork are called M,; and Mz and the branches of the posterior fork M34 and Cu,. The types of the new species here de- scribed and most of the material studied are deposited in the U.S. National Museum in Washington, D. C. Paratypes and other speci- mens when available will be furnished the Museum of Comparative Zoology in Cambridge, Mass., the British Museum (Natural History ) in London, and the Bermuda Biological Station, St. George’s, Bermuda. Johnson (1913) mentioned only two species of the family Heleidae (= Ceratopogonidae) from the Bermuda Islands. One, which he de- scribed as new under the name Ceratopogon fur, was actually Ptero- bosca fusicornis (Coquillett) ; the second species he referred to only as Ceratopogon sp., without notes that would give us a clue to its identity. Ogilvie (1928) does not mention this family as occurring in Bermuda, nor does Waterston (1940). 1Contribution No. 226 of the Bermuda Biological Station.

Previous to his death, due to slowly failing heart action, he had been partially incapacitated by a stroke for a considerable period. Dr. McIndoo was born. at Lyons, Indiana, April 11, 1881. After completing his early education, he entered the University of Indiana from which institution he received a degree of A.B. in 1906. Follow- ing his graduation, he taught in high school in Wisconsin, 1906-08. 44 PROC. ENT. SOC. WASH., VOL. 59, NO. 1, FEBRUARY, 1957 He then reentered the University of Indiana and received an A.M. degree in 1909. As a Harrison fellow, he matriculated in the same year at the University of Pennsylvania and was awarded the degree of Doctor of Philosophy in Zoology in 1911. In addition to the foregoing educational pursuits and practices, Dr. McIndoo assisted at the Uni- versity of Indiana, 1905-06, and in the summer of 1905 collected blind fishes in caves of western Cuba as well as other fishes indigenous to the fresh and salt waters of the island. He also attended the Biological Station of the University of Indiana, the Woods Hole Biological Sta- tion, the George Washington University, and the United States De- partment of Agriculture Graduate School. Dr. McIndoo’s later interests in and researches on the sense organs and responses of insects to various stimuli were largely initiated by his studies at the University of Pennsylvania which resulted in the publication of his thesis entitled ‘‘The Lyriform Organs and Tactile Hairs of Araneads.”’ The Bureau of Entomology of the United States Department of Agriculture appointed Dr. MecIndoo to its staff in 1911 and assigned him to the Division of Fruit Insect Investigations. After serving in this and other divisions for a period of 34 years, he retired as a senior entomologist in 1945. During his long and distinguished career, Dr. MeIndoo’s researches received world-wide recognition, particularly in the field relating to the olfactory and other sense organs of insects belonging to the orders Hymenoptera, Coleoptera, Lepidoptera, Diptera, and Orthoptera. He developed the well-known MeIndoo olfactometer, which instrument was extensively used in his studies on insect attractants and repellents. In addition to Dr. McIndoo’s researches in the science of osmies, he made extensive investigations of derris, cubé, and other rotenone-bear- ing plants to evaluate their usefulness for the destruction of insect pests. Dr. McIndoo was the author or coauthor of 84 publications and was particularly adept in making detailed pen and ink drawings to illus- trate the text. Dr. McIndoo was a past president of the Entomological Society of Washington, a fellow in the Entomological Society of America, and a member of the American Society of Zoology and of the Insecticide Society of Washington. In addition, he participated actively in many civic organizations of the Washington area. Dr. McIndoo will always be remembered as a modest man, a con- scientious worker and a gentleman in every respect. He will be greatly missed by all who had the good fortune to know and associate with him. He is survived by his widow, Emma P. McIndoo, two children, Thomas M. and Mary, and two grandchildren. E. H. SIEGLER PROC. ENT. SOC. WASH., VOL. 59, NO. 1, FEBRUARY, 1957 45 SOCIETY MEETING The 657th regular meeting of the Entomological Society of Washington was held on Thursday, November 1, 1956, in room 48 of the U. S. National Museum. There were 54 members and 52 visitors present. President R. A. St. George called the meeting to order at 8:00 p.m. and the minutes of the previous meeting were read and approved. The following new members were elected: Fred A. Morton, Entomology Branch, Office of the Chief of Engineers, Depart- ment of the Army; Dr. Lafe R. Edmonds, Engineering Research and Develop- ment Laboratory, Fort Belvoir, Va.; William L. Downes, Jr., Insect Identification and Parasite Introduction Section, U. S. National Museum, Washington 25, D. C.; Robert V. Travis, U. 8S. Department of Agriculture, Plant Industry Station, Belts- ville, Md.; John Knox Clagett, 6909 Carleton Terrace, College Park, Md.; and Max W. McFadden, 2040 Eye St. N.W., Washington 6, D. C. F. W. Poos, in behalf of the nominating committee, reported on the proposed officers for 1957. (Note: Officers for the year 1957 are presented on the inside front cover.—Ed.) President St. George thanked Dr. Poos for presenting the report in behalf of chairman W. H. Anderson, and thanked the committee, of which the third member was W. D. Reed, for preparing the slate of nominations. Some corrections offered by members to the proposed constitutional change presented at the previous meeting were discussed by President St. George. Voting on the proposals was deferred until the annual meeting in December, because of the large number of visitors present. Randall Latta brought greetings to the Society from the American Entomologi- cal Society, which he addressed at its regular meeting in the Academy of Natural Science in Philadelphia in September. H. H. Stage exhibited a pendant of amber containing several fossilized insects. W. E. Bickley announced that the ‘‘woolly-bear’’ prediction this year was for a mild winter, and that this is to be his final observation on the subject. Presi- dent St. George recalled seeing the statement that woolly-bears are unreliable forecasters. RR. H. Foote exhibited ‘‘ Aquatic Insects of California,’’ edited by Robert L. Usinger. Jerome G. Rozen reviewed ‘‘A Revision of the Genus Pselaptrichus Brendel,’’ by Robert O. Schuster and Gordon A. Marsh, and ‘‘ A Classification of the First-Instar Larvae of the Meloidae,’’ by J. W. MacSwain. CG. F. Rainwater gave a note on the status of the Mediterranean fruit fly pre- pared by the Plant Pest Survey Section. In Florida 11 new infestations were found during September in known infested counties. The last infested county was Osceola found two months ago. By the end of September, 168 infestations were known in 27 counties. There were 38,825 traps in the field, 36,000 in 39 counties in Florida. The remainder were in Alabama, California, Georgia, Louisi- ana, Mississippi, and Texas. No flies have been found outside of Florida. A total of 3,853,674 acres have been treated with bait spray and 26,673 acres have received surface treatment with granular insecticides. 46 PROC. ENT. SOC. WASH., VOL. 59, NO. 1, FEBRUARY, 1957 Of the area treated by aircraft with bait spray, 1,331,735 acres were Ccov- ered under Federal contract and 2,249,270 acres under State contract. Aireraft was used to treat 8,167 acres with granular insecticides, and ground equipment to spray 17,442 acres with bait spray and 22,446 acres with granular insecticide. Treatment is still being applied to 246,000 aeres, which is a reduction of some 65 percent from the original spray area. The fly has exhibited a marked ability to build up rapidly when eontrols have not been properly timed. On September 26 certification was waived on all regulated vegetables produced in all Federally regulated counties except Pinellas. (Speaker’s abstract.) The principal paper of the evening, ‘‘ Malaria Control Problems in Indo-China,’’ was given by Harry H. Stage, Malaria and Vector Control Specialist (until retire- ment October 31, 1956), International Cooperation Administration, Vietnam. Dr. Stage introduced Dr. Louis Williams, Jr., Pan American Sanitary Bureau, regional office of the World Health Organization. The problems encountered in efforts to control malaria in Indochina are many and varied. Some of them are concerned with lack of trained personnel. Such problems can be resolved, although that requires time and local interest. Others are more complicated because they are closely associated with the very life of the people their habits, their ideology, and their security. These latter prob- lems do not yield easily to western ideas of organization and management, and they should not be subjected completely to our kind of logic. Rather, we for- eigners must bend to unaccustomed lines of approach and emphasis. These latter problems—indefinite, in some cases unmentionable—are no less vital to us who undertake a disease-control project than problems having to do with the insect vector itself. In Vietnam the problem is especially complicated because there are some 700,000 tribal Indonesians living in remote mountain areas and who contribute little to the economy of the country. The Vietnamese are therefore inclined to disregard them in health programs and social welfare. The problems of military insecurity, transportation, trained personnel, and customs, require special consideration and thought. The problems having to do with finances are not those involved in inadequacy of funds; rather, they are concerned with pro- cedures for getting the money to the end point. The steps are many and tor- tuous, and sometimes there are leakages enroute. There are 22 species of An- opheles, probably only three of which, A. minimus, A. jeyporiensis, and A. sun- diacus, are effective vectors. These have very definite habitat requirements, however, and so cause a ‘‘spotted’’ incidence over the nation. Emphasis should be placed on one of the greatest problems—and weaknesses—in the Indochinese Malaria Control Programs, that of inadequate supervision. Without it anopheline resistance will be promoted and this in turn will make the task of eventual ma- laria eradication difficult indeed. (Speaker’s abstract.) Dr. Stage’s slides were an excellent complement to his talk, which was fol- lowed by questions and comments by Doyle Reed, Margaret Walton, Louis Wil- liams, Reece Sailer, and others. Two new members were introduced, Lafe Edmonds and Fred Morton. The visitors introduced were Frederico and Anna Lane of Brazil, Major Tibor Lépes of Yugoslavia (where his name would be given as Lépes Tibor), Mrs. Stage, Mrs. Lucie C. Timberlake, and Dr. J. Bonne-Wepster, of the Netherlands. The meet- ink adjourned at 9:48 p.m.—Keuulir O’NeiuL, Recording Secretary. PROC. ENT. SOC.

Y. 20, N. Y. Pyrenone HELPS TO PRESERVE PRINCIPLE OF NATURAL CONTROL Pee quickly kills destructive, annoy- ing and disease-carrying insects. In the absence of sunlight, it remains effective for long periods of time. In fact, a single application of Pyrenone protects stored grains from insect at- tacks for an entire storage season. On growing crops Pyrenone kills the accessible stages of insects fast —even between showers of rain. Yet natural factors of rain and sunlight do not permit Pyrenone to form long-lasting residues. Be- cause long-lasting residues are not present, the newly emerging parasites and predators are free to com- plete their life cycles and to continue to parasitize or feed upon destructive insect pests. This means that Pyrenone is completely com- patible with the natural control of crop-destroying insects. eal an cfefe (OLN Vetere LON ian Jaa Hl On FAIRFIELD CHEMICAL DIVISION Food Machinery and Chemical Corporation 1701 Patapsco Avenue « Baltimore 26, Md.

PROCEEDINGS OF THE PME ONEOLOGICAL SOCIETY .OF WASHINGTON VOL. 59 APRIL 1957 NOS 2 AMERICAN SPECIES OF LEDERMUELLERIA AND LEDERMUELLERIOPSIS, WITH A NOTE ON NEW SYNONYMY IN NEOGNATHUS (ACARINA, STIGMAEIDAE, CALIGONELLIDAE). F. M. Summers, University of California, Davis The mites that Oudemans (1923) referred to his genus Ledermuel- leria comprise a homogeneous group of stigmaeids having globate bodies almost completely encased in an ornamented exoskeleton. They occur as thinly dispersed inhabitants of ground litter, leaf mold, moss, and meadow land. Three of the four Ledermuelleria species and the one species of Ledermuelleriopsis collected principally in California are species described from Europe. Redescriptions of the named species are needed because existing descriptions do not clearly indicate their distinguishing features. A distinctive feature of these two genera is the extensive encase- ment of the hysterosoma by one (Ledermuelleria) or two (Leder- muelleriopsis) dorsal plates. These plates constitute a carapace-like covering over the entire dorsum and sidewalls of the hysterosoma. The humeral (scapular) plate on each side is displaced to a pleuro-ventral position. LEDERMUELLERIA Oudemans Ledermiilleria Oudemans, 1923, Ent. Ber. 6(130) :150. Globate, red or straw-colored mites with stubby legs and mouthparts. Palpus 5-segmented, thickset, longer than extended chelicera by two distal segments; overall length not greater than combined lengths of genu, tibia, and tarsus of leg I. Primary claw of palptibia well-developed, with a very small accessory claw anchored medially at its base. Palptarsus a slender cylinder, equal to or slightly longer than primary claw; equipped with five acicular setae, a peglike sensillum, and a stubby, trifid sensillum at its apex. Chelicerae independently movable, with retractile stylets much shorter than inflated basal segments. Idio- soma arched dorsally, its posterior end with a shallow suleus which delimits a ‘caudal protuberance,’’ on the inferior surface of which is located a pair of ano-genital valves. Dorsum almost wholly shielded with three sculptured plates: one covering propodosoma, one covering hysterosoma to lateral margins of venter, and one caudal plate covering posteriormost protuberance and part of ventral opisthosoma. Humeral (scapular) plate large, triangular, displaced ventrally with apex intruding between coxae II and TIT. All of these plates tessellated or uniformly dimpled. Two or four sternal plates; the two between opposite 50 PROC. ENT. SOC.
