middle coxae whitish; the long bristle on the outer surface of the

sharply-defined black band which is as wide as the second tarsal joint 

 is long; hind tarsi scarcely half as long as their tibiae, black with the 

 basal half of the first joint whitish, first joint longer than the second, 

 the following joints regularly decreasing in length; fore and middle 

 tarsi about the same length as their tibiae, and with the last two joints 

 infuscated; fore metatarsi about one-half as long as their tibiae; mid- 

 dle metatarsi about one-third the length of their tibiae. Wings gray- 

 ish hyaline, narrowed at base, and with the anal angle nearly obso- 

 lete (Fig. 2), last section of fourth vein nearly straight, and only 

 slightly approaching the third towards the tip, ending in the apex of 

 the wing. 



Female. One female that agrees with these males in the coloration 

 of the legs and antennae in having white hairs and bristles on the 

 fore and middle coxae, and a yellow bristle on the hind coxae, I am 

 placing as the female of this species. The dorsum of the thorax is 

 brown covered with gray pollen, leaving five vittae, the central one 

 being the most sharply defined and the outer pair the most poorly de- 

 fined. The abdomen is altogether brown except the venter which is 

 yellowish. Wings with the anal angle more prominent than in the 

 male, and more tinged with brown; the fourth vein ends in the tip 

 of the wing. Length 3.5 mm. 



Described from two males and one female from New Mex- 

 ico. The males are in the collection of the American Ento- 

 mological Society, and were taken at Alamogorda, N. M., in 

 May. The female is in the National Museum and was taken 

 at Las Vegas, N. M., on August 9th. Am. Ent. Soc. Type 

 No. 5259. 



Note. The female of this species has the prescutellar de- 

 pression very distinct, in the male it is not so conspicuous. 



This species is easily separated from all others of the genus 

 by the coloration of the hind feet.
