A SYSTEMATIC STUDY OF THE ANTHOMYIINAE 



OF NEW YORK, WITH ESPECIAL REFERENCE 



TO THE MALE AND FEMALE GENITALIA 



H. C. HUCKETT 



In this paper Gii'schner's (1893) division of the Miiscidae calyptrae into 

 two major groups has been adopted as affording characters of greatest 

 taxonomic significance. These two groups are the Tachinidae, with 

 true hypopleural bristles present; and the Anthomyiidae, with true hypo- 

 pleural bristles absent but occasionally with hypopleural hairs. ^ Town- 

 send's correction (1914) follows accordmg to all accepted rules on nomen- 

 clatui'e; that is, since Musca Linn, has priority over Anthomjda Meig., 

 Muscidae must replace Anthomjdidae. The synonjaii}- is as follows: 



1758 Musca Linnaeus p.p. S3'st. Nat., 10th ed., p. 589-601. 

 1893 Anthomyidae Girschner p. p. Berl. ent. Ztschr., vol. 38, p. 311. 

 1907 Anthomyiidae Bezzi and Stein. Kat. Pal. Dipt., vol. 3, p. 599-747. 

 1921 Muscaridae Malloch. Ann. and Mag. Nat. Hist., vol. 7, p. 161. 



The family Muscidae includes the subfamilies Muscinae, Phaoniinae, 

 Fanniinae, Hydi'otaeinae, Lispinae, Anthomjdinae, Coenosiinae, and 

 Fucellinae (Malloch, 1917 c) . The subfamilj^ Anthomyiinae is distinguished 

 from the others bj^ the following combination of characters : the scutellum 

 on the ventral sm-face has a few fine hahs; the vein Cu2+2dA is pro- 

 duced to the margin of the wing; the sternoplem-al bristles are arranged in 

 the order 1:1, 1:2, or 2:2, never m the form of an equilateral triangle. 



Of the twenty-one genera of Anthomjdinae that are known to occur in 

 North America, nineteen are represented m New York. The genera 

 Macrophorbia Mall, and Alliopsis Schnb. and Dzied. are at present unre- 

 corded; the genera Acroptena Pokorny, Chortophila Macq., Dohchoglossa 

 Stein, Ganperdea Aldr., Hylephila Rond., Phorbia Rob.-Desv., Xenophorbia 

 Mall., and others, are listed in this paper under their respective synonymies. 

 The classification of the genera Hjdemjda Rob.-Desv. and Pegomjda Rob.- 

 Desv. is at present in an unsatisfactory state. The ^^Titer feels that, out 

 of the great crowd of species gathered here, lesser units may 3'et gain 

 recognition, but a fuU appreciation of their extent and Imiitations has not 

 yet been definitely perceived. 



' The character of the vein Afi+2, which has separated the Anthomyiidae from the Muscidae, is no 

 longer dependable owing to the deflection of the distal part of the vein from a very slight angle to one 

 indistinguishable from that as found in ^luscina. A completed series of such a variation includes a large 

 number of tj-pical Anthomyiidae, for example, Phaonia, Limnophora, Euiimnophora, and Bucephalumyia.
