401New Diptera Names in Hawaii.BY t. H. BRYAN, JR.(Presented at the meeting of July 11, 1929)Keeping up with entomological synonymy may to some workersbe a pleasing and fascinating sport. To most of us it is a delusive drudgery. Each time a taxonomic publication dealing withthe insects of the Pacific region appears, I look through it with asinking feeling, to see how many familiar and long-establishednames have been pushed into the discard, and what has been perpetrated in their stead.The most recent publication thus perused was "DipteraBrachycera and Athericera of the Fiji Islands," by the late MarioBezzi, published by the British Museum, 1928. In this little bookare listed 239 species of flies found in Fiji. Of these 27 alsooccur in Hawaii. But of the 27 the names of 10 have beenchanged, or at least are different from those by which the speciesare locally known.The species common to both Hawaii and Fiji are as follows:DOUCHOPODIDAEMedetera femoralis Becker.Psilopus pallidicorne (Grimshaw) is noted as being in thegenus Chrysosoma Guer., a Fiji species C. greenwoodi, being veryclose to it.Chrysosoma patellifer (Thomson), described from Guam, isfound in Fiji, but differs from the species known as Psilopas orGnamptopsilopus patellifer Thomson recorded by Grimshaw andothers from Hawaii. Our species is something else.SyrphidakIschiodon scutellaris (Fab.) is the latest name for the speciesrecorded from Hawaii by Howard, Grimshaw and others asXanthogramma grandicornis (Macquart) and more recently calledSiinosyrphus grandicornis (Macquart) by Curran.Proc. Haw. Ent. Soc, VII, No. 3, April, 1931.402Volucella obesa Fabr. is common in both groups. AlthoughBezzi had no specimens from Fiji, I collected it there.Syritta oceanica Macquart.PhoridakBezzi records Aphiochacta xanthina Speiser as being bred fromdiseased pineapple suckers from Hawaii. 19-11-1922 (Simmonds).Our species here in Hawaii has been known as Aphiochactascalaris (Loew).OrtaudaeBuxesta quadrivittata Macquart—( = Euxesta annonae Loew(nee Fabr.) as recorded in Hawaii by Grimshaw and others.)Acrosticta pallipes Grimshaw, originally described from Hawaii,but subsequently recorded from South America (Bolivia andPeru) by Handel, in 1909.Scholastes bhnaculahis Handel, whose maggots breed in fallencoconuts.PiophiudaePiophila casei (Linn.), the cheese skipper.Rhodesiella nitidifrons Becker is perhaps the same as Rhodesi-ella tarsalis Adams, found in Hawaii.DrosophiudaeDrosophila anipelophila Loew, which we call D. melanogasterMeigen.Borboridae;Leptocera ferruginata Stenhammar. Two other species recorded from Fiji may also be among the undetermined tiny Bor-borids known in Hawaii.403MlUCHIIDAEMilichiella lacteipennis Loew.Desmometopa m-nigrum Zetterstedt. Dr. Aldrich has recentlydecided that our species in Hawaii is D. tarsalis Loew. These mayor may not be the same.AgromyzidasOphiomyia lantanae (Froggatt) is a new name for the lantanaseed fly, introduced from Mexico, and locally known as Agromyzalantanae Froggatt.Liriomyza pusilla (Meigen) is a new name for the serpentineleaf-miner, common in North America, Hawaii, and other localities, and formerly in the genus Agromyza.AnthomyiidaeAtherigona excisa Thomson var. trilineata Stein (=A. pul-vindta Grimshaw).Ophyra nigra (Wied.) Malloch.MuscidakSynthesiotnyia nudiseta v. d. Wulp.Musca domestica Linn. Bezzi records it as var. vicina, butMalloch (Insects of Samoa, Pt. VI, fasc. 3, p. 174, 1929) statesthat he does not accept M. vicina as distinct from M. domestica,saying that the only difference between the two forms lies in thecomparative widths of the frons in the two sexes.Stomoxys calcitrans Linn.GastrophiudaeGastrophilns nasalis Linn.Chrysomyia rufifacies Macquart (=Ch. albiceps Wiedemann).Chrysomyia megacephala Fabr.Rhinia testacea Rob.-Desv.404SarcophagidakSarcophaga dux Thomson.Sarcophaga fuscicauda Bottcher.TachinidaeMicroceromasia sphenophori (Villen.) (=Ceromasia spheno-phori Villen.) the valuable little tachinid parasite of the sugar canebeetle borer, introduced from New Guinea.Dr. Bezzi prefaces his book with some very interesting remarkson the character and origin of the Diptera fauna of Fiji. Hestates that 60.5 per cent, or 144 species, of flies are endemic; ofwhich he describes 95 per cent as new; 6.3 per cent are listed asspecies from other Pacific islands; 6.7 per cent are from the eastcoast of Australia, Tasmania, New Zealand and New Guinea;5.4 per cent are Austro-Malayan species; about the same numberare oriental, chiefly from Java, Formosa and the Philippines; thesame number are Ethiopian-Austro-Malayan; and 8.4 per cent arecosmopolitan, or found generally throughout the tropics. Thus,four-fifths are endemic, Pacific or Austro-Malayan, and the remaining one-fifth are of wide distribution, for the most partassociated with man.
