 ated by a distance about equal to the first and half of the second 

 joints of flagellum ; space between hind ocelli less than that separ- 

 ating them from eyes ; antenna? rather long, acuminate, the first 

 joint of flagellum about one-quarter longer than second; prono-

 convex sloping from base to apex, not impressed ; legs rather slender, 

 fairly spinose, serration of hind tibia? distinct, longer spur of latter

 of flagellum; space between hind ocelli slightly less than that be- 

 tween them and eyes ; first joint of flagellum about one-sixth, or less, 

 longer than second; pronotum angulate behind ; middle segment 

 short, not rounded, but rather sloping from base to apex, but not
