part, and a band beyond the middle of about the same width, somewhat 

 angulated in front, third segment similar, except the anterior border may 

 be quite narrow and the cross band sub-interrupted, fourth segment in 

 male wholly bronze, concealing the hypopygium, in female with very nar- 

 row front border and narrow interrupted cross band ; the black is attenu- 

 ated on the sides, not quite reaching the lateral margins. Legs yellow, 

 femora rather stout, anterior and middle pairs mostly brownish or black, 

 sometimes prevailing yellow blackish above, posterior femora varying from 

 a blackish ring near the base, to almost wholly black, below with short 

 black bristly hairs near this end ; three last joints of tarsi black. Wings 

 smoky hyaline, stigma yellowish brown, small cross vein near outer third 

 of discal cell. Long c. 12-16 mm., 10 specimens. Mt. Hood, Oregon; 

 Washington Territory (H. K. Morrison). 



The fasciate abdomen of this species differs from all known Br achy- 

 palpi ; the spines below the hind femora are also quite small. Its pilosity 

 will hardly allow it to be placed with Xylota ; besides, the face is not so 

 receding as in that genus. The structure of the head is very much like 

 the preceding genus. Its resemblance to Sterphus Ph. (1. c.) from Chili, is 

 quite as great. 



Enge?iiafnyia gen. nov. Allied to Brachyopa, but differs in the face being 

 tuberculate, not carinate, rather more produced and less truncate, and in 

 the abdomen being long as in Xylota. There are also well developed 

 scutellar, postalar, dorsopleural and mesopleural bristles.* 



Eugenianiyia mfa, sp. nov., ^ . Red. Head and antennae yellowish red, 

 first two joints of antennae very short, third joint sub-quadrate, arista 

 plumose. Dorsum of thorax darker, almost brownish red, with very short 

 black hairs, and with two rather broad poUinose stripes, abbreviated 

 behind, and enclosing in front a black spot not reaching the suture. 

 Pleurae with sparse yellowish white pile. Abdomen narrower than the 

 thorax and much longer, nearly bare, shining, somewhat blackish towards 

 the end. Legs red, basal joints of tarsi yellowish, terminal joints black- 

 ish, femora considerably swollen, with tufts of yellowish white pile below 

 near the base, the middle and more especially the posterior pairs and pos- 

 terior tibiae with sparse short bristle-like spines. Wings clouded with 

 brownish on the anterior part, sub-hyaline behind. L c. 14 mm.; 1. a. 

 ID mm. One specimen, Washington Territory (H. K. Morrison).
