ART. 7 AMEEICAN MUSCOID FLIES IN VIEN'N'A MUSEUM ALDEICH 21 



The genus differs from Phorocera in having the head more 

 rounded, first vein hairy, and abdomen narrow. The female prob- 

 ably has a piercer, as Brauer and Bergenstamm say the venter is 

 ""stufig" (in steps). 



The genitalia (fig. 1) are much like those of Phorocera {Eupkoro- 

 ■cera^ Neophorocera) claHpennis Macquart, of the United States; 

 the united inner forceps form a 

 convex disk basally with a slight, 

 shining median ridge, the apex 

 drawn out into a slender process 

 slightly curved up; the outer 

 forceps are reduced to flat 

 plates. Both pairs brown in color. 

 The fourth abdominal segment 

 is greatly shortened below, the 

 sternite small and almost invis- 

 ible. 



Not in the National Museum.

Phorocera heros Schiner, Novara Reise, 1868, p. 325, 



Neomintho heros Brauer and Bekqenstamm, Denk. Wien. Akad. Wiss., vol.

 Phorocera coccyx Aldrich and Webber, Proc. U. S. Nat. Mus., vol. 63, art. 

 17, 1924, p. 64. 



Two males, " Brasilien," 

 one is " Coll. Winthem " and 

 the other is apparently from 

 the same lot. 



I have spread the genitalia 

 of these males and find them 

 to be of the same species 

 described a.sPhorocera coccyx 

 by Aldrich and Webber in 

 1924 from Virginia, New 

 York, and Indiana. Speci- 

 mens received later are from 

 Maryland, Oklahoma, and 

 Cordoba, Mexico. Since Schiner mentioned only a female in the 

 original description, it might be thought that neither of the Brazilian 

 specimens received from the Vienna Museum could be the type. How- 

 ever, it seems clear that Schiner made a mistake regarding the sex. 

 He gives the length as 15 mm., agreeing with these males, while in 

 this species the female has a shorter abdomen, our single specimen of 

 this sex measuring only 9 mm. The description of coccyx is accessible 

 and need not be repeated, but I add a figure of the unique genitalia
