250 NORTH AMERICAN ANTHOMYIID FLIES OF GENUS PHAONIA 



Phaonia consobrina (Zetterstedt) 



Anthomyza consobrina Zetterstedt, Ins. Lapp., p. 665, 1834. 



I have before me a European male of this species, obtained 

 from Mr. R. Frey, which was named by Stein. The latter 

 records the species from this country, basing his identification 

 on specimens taken in Colorado. I have not seen his specimens, 

 and have seen no examples from this country which are identical 

 with the one from Europe. In his paper Stein gives a key to 

 the species of the genus, and judging from that I consider it 

 probable that what he had before him was not consobrina, but 

 brunneinervis Stein, as his type specimens runs down to con- 

 sobrina in the key. The European specimen I have is quite 

 different from brunneinervis, so we may retain the latter in our 

 list, though I fear we have no grounds for the retention of 

 consobrina. 



Length, 8 mm. 



Phaonia incerta new species 



Male. — Similar in color to consobrina and brunneinervis. The calyptrae 

 are, however, white with the margins faintly yellowish and not yellowish 

 throughout; the wings are but shghtly infuscated at bases, whereas in the 

 other species they are slightly but distinctly brownish at base and along the 

 courses of the -veins on basal half or more; the large black subtriangular 

 black mark on each abdominal tergite is more distinct than in consobrina. 



Eyes densely hairy, the hairs about twice as long as in consobrina, frons 

 similar, the orbits with fine short hairs on posterior half, bristled on anterior 

 half; arista with the longest hairs not much longer than its basal diameter. 

 Fore tibia with a fine long setulose hair on posterior surface beyond middle; 

 mid femur with three or four bristles on basal half of postero ventral surface 

 and also numerous long hairs; mid tibia without any anterodorsal bristles, 

 with four on posterior side in an irregular series, and two on posterovcntral 

 surface; hind femur with a complete series of bristles on antero ventral surface 

 and some on basal half of posteroventral; hind tibia with two or three antero- 

 dorsal and anteroventral bristles, the anterior and posterior hairs setulose 

 but not very long; apical posterodorsal bristle small but distinct. 



Length, 7 mm. 



Type. — Yakutat, Alaska, (J. S. Hine), [Ohio State University]. 



This species resembles both consobrina and brunneinervis, being 

 distinguished from the former as indicated in the foregomg de- 

 scription, and from the latter by the lack of anterodorsal bristles 

 on mid tibia, and the much weaker setulose hairs on the postero- 

 ventral sui-face of the fore til^ia.
