This species differs from the preceding in being of a 



darker color, and in having the hind femora somewhat 



ferruginous, besides that the wing-covers differ somewhat 



in their markings.

This species, except in the length of wings and wing- 

 covers, is very similar to N. exiguus ; it is somewhat 

 larger, and has the terminal half of the last joint of max- 

 illary palpi, black ; the elytra in both sexes are light 

 brown, with the veins darker, especially in the female, and 

 extending to the extremity of the body ; the wings in 

 both sexes are as long again as the body, and the oviposi- 

 tor of the female is so long as nearly to reach their tip. 

 Length of ovipositor, .25 in. 4 specimens.
