276 NORTH AMERICAN ANTHOMYIID FLIES OF GENUS PHAONIA 



tellum and margins of pleural sclerites yellowish. Abdomen with an in- 

 distinct dorsocentral vitta and lateral checkerings black. Legs including 

 coxae yellow, tarsi slightly infuscated. Wings clear, veins l:)asally, and calyp- 

 trae and halteres .yellow. 



Eyes almost bare; frons at vertex about one-third of the head-width; slightly 

 wider anteriorly; orbits narrow, the bristles strong, few hairs adjacent to the 

 bristles; jiarafacials narrow; cheek about as high as width of third antennal 

 segment; third antennal segment twice as long as second; longest hairs on 

 arista distinctly longer than width of third antennal segment. Thorax 

 without distinct presutural acrostichals; postsutural dorsocentrals three; 

 prealar almost as long as the bristle behind it; anterior intra-alar very strong. 

 Fore tibia with two anterodorsal and two posterior bristles; fore tarsus slender, 

 longer than tibia, basal segment with some rather long sensory hairs along 

 posterior side; mid tibia with four or five bristles of unequal lengths on pos- 

 terior side in an irregular series; hind femur with a complete series of sparse 

 bristles on anteroventral surface, and some fine bristles on basal half of 

 postero ventral; hind tibia with two anterodorsal and four or five anteroventral 

 bristles, the apical posterodorsal bristle small but distinct. Fourth wing-vein 

 slightly but distinctly curved forward apically (fig. 21). 



Length, 8.5 mm. 



Type.— New London, Connecticut, July 10, 1916, (R. C. 

 Osborn), [Ohio State University]. 



Phaonia solitaria Stein 



Phaonia solitaria Stein, Arch, fiir Naturges., 1918, abt. A, heft, 9, p. 15, 1920. 



This species, which I have not seen, is closely related to the 

 following two. Johannsen in describing apicata placed it in 

 the subgenus Euphemia, because some specimens had a more or 

 less distinct pair of presutural acrostichal bristles. Stein sepa- 

 rates solitaria from the other species which he has keyed by the 

 presence of these bristles, solitaria having a pair present and the 

 others lacking them. His specimens of solitaria included one 

 from Ithaca, probably sent from Cornell, and as Johannsen 

 described apicata from that locality I believe I am right in 

 assuming that solitaria is merely a variant of the former, 



I have a male sent to me by Dr. Aldrich, and taken at Peter- 

 sham, Massachusetts, which has, besides a distinct pair of pre- 

 sutural acrostichals, four dorsocentrals at least on one side; the 

 other side is damaged by the pin so that it is impossible to say 

 how many there are. 1 believe this specimen is merely a variant 

 of apicata.
