TAXONOMY OF MUSCOIDFAN FLIES — TOWNSFND I35 



This form comes nearer agreeing with Wiedemann's description 

 of plumipes than anything that has turned up since Bosc's time. It 

 differs therefrom only as above described, and principally in the 

 black scutellum. 



Mr. van der Wulp (1. c.) has described this species from what he 

 records as one male and four females, but says nothing as to whether 

 the apical cell is petiolate or closed in the margin, nor does he men- 

 tion the shape of the abdomen in the sexes. It seems quite certain 

 that his specimens are this species, and it is likely that all five of 

 them have the apical cell moderately long petiolate. 



Genus Trichopoda Latreille 



This genus, as here restricted, has the wings with inner margin 

 narrowly hyaline, hind femora not ciliate at all ; only male with yel- 

 low in wings, no milky radiations, apical cell very short petiolate, 

 and tegula? yellowish. Type, T. pennipes J. C. Fabricius. Parasitic 

 in Heteroptera (Anasa, Leptoglossus), so far as known. 



GALACTOMYIA, gen. nov. 



This genus is proposed for Trick, radiata H. Loew. Trich. 

 lanipes J. C. Fabricius (description is of female; T. formosa Wiede- 

 mann is the male) also belongs in this genus. 



The males have the abdomen flattened ; the wings infuscate to 

 inner margin, milky radiate on a yellow or fuscous background, the 

 milky radiations conspicuous and the yellow less pronounced. Hind 

 femora strongly ciliate on posterior half, with flattened bristles. 



The females have the abdomen cylindrical ; the wings wholly black 

 except narrow inner border, without yellow coloring, the internal 

 border abruptly limpid. Hind femora at least short-ciliate distallv, 

 though bristles may not be flattened. G. radiata female has the 

 abdomen reddish, with at most the apical half black. G. lanipes 

 female is to be distinguished by its wholly black coloration, aside 

 from the usual yellow of head, thorax, claws, and pulvilli. 



It is yet uncertain what species can be referred to this genus be- 

 sides radiata and lanipes (syn. formosa Wiedemann). As to the dis- 

 tinctness of these two species, Loew pointed out in his description of 

 radiata (male) that it has the palpi reddish yellow, abdomen purple 

 black, and bases of femora yellow. G. lanipes (male) has palpi 

 black, abdomen obscure rufous, and femora wholly black. 



The males of Galactomyia have ventral membrane widely visible, 

 and all the ventral plates free. There are six abdominal segments, 

 the first extremely short and not visible above unless abdomen is
