so throughout), well elevated, and about half as long as hypopygium, 

 and the other lying on the inner side, narrower, somewhat curved and 

 not so much elevated. (Fig. 6). Length 16-20 mm. 



This species is most easily separated from L. aimatis n. sp. 

 by the essentially black seventh segment.

 (Washington Territory.) 



Ground color shining black. Mystax black; decumbent pile on 

 face, beard, pile of tibiae decreasing in amount on posterior pairs, pile 

 of pleurae and periphery of thorax, scutellum and abdomen, more abun- 

 dant posteriorly and on sides and hind margins of segments, light 

 greenish yellow to pale golden. Pile of occiput mixed with black, and 

 short nearly erect pile on disk of thorax black. Hair on coxae pale 

 golden, on femora mixed black and golden. Wings fumose hyaline, 

 veins reddish. Male forceps with median brush like lamella and 

 narrower curved, inner process not reaching end of forceps. (Fig. 7). 

 Length 14-20 mm.

Specimens examined: Wellington, B. C, (Hine); Summit

Laphria vivax anthemon new subspecies. 



A male from the top of Las Vegas Range, New Mexico, 

 11,000 feet, W. P. Cockerell. 



Differs from the typical form in having the median lamella of 

 forceps more solidified, the inner process projecting beyond end of 

 forceps, (Fig. 8) and the vestiture in general more highly colored. 

 The facial pile, beard and pile of abdomen are bright golden and thoracic 

 fringes and tibial hair red gold. On account of the more intense color 

 of the abdominal pile, this appears denser than in vivax and as it is most 

 abundant along posterior margins of segments, gives the insect a more 

 distinctly banded appearance. Wing veins more distinctly reddish. 

 Length, 18 mm.
