Malloch — Anthomyiidae from Vicinity of Washington, D. C. 3 



This genus is related to Hammomyia but the much more elongate head 

 readily separates it from that and all other genera known to me. The 

 genus belongs to the subfamily Anthomyiinae, but differs from most re- 

 lated genera in having no anteriorly directed supraorbital bristle, and I 

 know of no other genus possessing the peculiar curved apical hind tibial 

 spurs. An additional character for the separation of the genus from 

 Hammomyia is found in the presence of the interfrontal cruciate bristle. 



Phaonia winnemanae, sp. n. 



Male. — Black, slightly shining. Frontal stripe brownish red, orbits with 

 white pilosity ; cheeks paler than frons ; face gray ; antennae reddish testa- 

 ceous, third joint except base blackish brown; arista reddish testaceous; palp 

 reddish, slightly darkened at apices. Thorax rather distinctly quadrivittate 

 when viewed from behind; humeri, lateral margins of disc posteriorly, 

 scutellum, and regions surrounding both spiracles testaceous. Abdomen 

 with dense brownish gray pruinescence and a distinct dorso-central dark 

 stripe. Legs yellow testaceous Wings yellowish, noticeably so at base. 

 Calyptra and halteres yellow. 



Eyes almost nude, separated at narrowest part of frons by a distance 

 greater than width across posterior ocelli; orbits linear, not obliterating 

 the rather wide interfrontalia; arista plumose to tip, the longest hairs 

 very distinctly longer than width of third antennal joint; cheek at narrow- 

 est part slightly higher than width of third antennal joint; marginal bristles 

 strong, all directed downward and slightly forward. Presutural acrosti- 

 chals absent,. 4-6 series of weak hairs between presutural dorso-centrals ; 

 3 pairs of postsutural dorso-centrals present; prealar bristle nearly as 

 long as the one behind it; scutellum with 4 strong and 2 weak basal marginal 

 and 2 weak discal bristles. Fifth abdominal sternite with a large deep 

 V-shaped notch in posterior margin. Fore tibia with a few short setulae 

 on apical half of antero-dorsal surface, no posterior bristle at middle; 

 mid tibia with 3 or 4 posterior bristles; hind femur with a complete series 

 of bristles on antero-ventral surface and a few weak bristles on basal half 

 of postero-ventral ; hind tibia with 4 or 5 antero-ventral, 5 or 6 anterior, 

 2 or 3 antero-dorsal and 1 postero-dorsal bristles, and a series of small 

 setulae on posterior surface. Outer cross-vein straight. 



Length, 7 mm. 



Type locality, Plummers Island, Md. June 17, 1906 (W. L. McAtee). 

 One specimen. 



This species resembles pulvillata Stein more closely than it does any 

 other North American species known to me. It differs, however, from that 

 species in having a series of bristles on the anterior surface of hind tibia 

 in addition to those on the antero-ventral and antero-dorsal surfaces, the 

 eyes hairy, and the frons much wider. 



In some respects the species resembles apicata Johannsen and pallidula 

 Coquillett. From the former it is readily separated by the entirely yellow
