second, third and fourth sections of the costa proportioned 1 : 1.4 : 0.6, 

 anterior cross-vein at three-fourths the length of the discal cell, the 

 posterior cross-vein a little before the end of the first vein, fourth vein 

 ending at the wing-tip, its sections proportioned 3 : 1 : 9, basal section 

 of the fifth vein slightly longer than the outer, marginal cilia much 

 longer than the anterior cross-vein, nearly as long as the posterior 

 cross- vein. 



One specimen, in the U. S. National Museum. Cordoba,

 prescutellar dorsocentral, two scutellar bristles; pleura polished. 

 Pygidium large, ovate, closed, its hairs short, sparse and pale. Legs 

 black, the under side of the anterior femora reddish brown, hind femora 

 with two preapical bristles, hind tibiee with three apical bristles and with 

 a strong spur, but without extensor bristles. Halteres fuscous, calyp- 

 teres margined with six cilia. Wings short and broad, lightly infumated, 

 the veins coarse and dark, margin uniformly short-ciliate, second, 

 third and fourth sections of the costa proportioned 1.7 : 1.8 : 1, third 

 and fourth veins outwardly subparallel, anterior cross-vein at the 

 outer third of the second basal cell, the last two sections of the fourth 

 vein proportioned 1 : 9, of the fifth vein equal. 



Three specimens: Pullman, Washington, March 5, (Melan- 

 der), and Rock Creek, D. C, March 9 (R. C. Shannon). Par-

Eudrapetis pennescens, sp. nov. 



9 . Length 2.25 mm. Differing from armipes Bezzi in the following 

 respects: Legs blacker, the hind femora with only one pronounced knee 

 bristle, the hind tibiae with five or six long contiguous hair-like bristles 

 forming a feather-like row along the middle of the inner side and with 

 a strong terminal lappet and stout subapical bristles, the hind metatarsi 

 with blackish and not golden pubescence ; wings clear hyaline. Differing 

 from plumipes in being larger and more robust and in having the 

 mesonotum closely white-pubescent, the hind femora with a single 

 knee bristle and the wings hyaline. 



Shining black, pubescence white, bristles black, the narrow front, 

 linear face and lower orbits cinereous pniinose; legs almost black, the 

 hind tibiae dark brown; halteres white; veins black and strong. Palpi 

 blackish, oral margin polished, seta of the second antennal joint strong.
