of tibiae and tarsi luteous. Wings brownish on outer part; last two 

 sections of fourth vein nearly equal, short appendicnlate at the angle, 

 first posterior cell short petiolate. 



$ . Face nearly vertical and straight to just above the epistoma, 

 which is moderately produced. Pile of front darker. Dorsum of 

 thorax with rather thin lutescent pile. Abdomen broadly oval, the 

 fourth segment long, the fifth nearly concealed ; in color, shining black, 

 with a bronze reflection ; pile lutescent. 



Six specimens, Texas. Two other specimens from Georgia are a 

 little smaller, the third joint of the antennae is a little shorter, and the 

 abdomen is less metallic. The male has the face below the antennae 

 more concave, and the pile of the dorsum of the thorax more blackish 

 across the middle. Very likely there are two species here.

I identify a male specimen from Mount Hood as this. The pile of the 

 head and dorsum of tlie thorax is black. The fourth abdominal seg- 

 ment is shining metallic, like the anterior triangular spots on the sec- 

 ond and third segments ; the wings are very distinctly brownish in 

 front; and I cannot distinguish any pubescence on the arista.
