 but all other characters normal. One female, Los Angeles County, 

 California (Coquillett).

NOMADA LAMARENSIS Cockerell. 



This was described from a single male taken at Lamar, Colorado. 

 Mr. W. M. Mann sends me one of each sex from Canadian, Texas, 

 July 27 and 29, 1905. The male is larger than the original type 

 (fully 11 mm. long), and the black is much reduced, on the head 

 to the ocellar area, on the thorax to a slight stain along the anterior 

 edge of the mesothorax. All the tibiae are marked with yellow. 

 These differences are apparently not racial. The female looks like 

 the male, but the face is all red, with a shght yellowish suffusion on 

 each side. The legs show less yellow.

 abundant Nomada in Texas. The localities represented are:
