the third is more slender, and the fourth the smallest, terminating into 

 two curved spines or claws, between which is a subcircular fleshy disk. 

 The. rudimentary elytra are subovoidal, not extending backwards to the 

 posterior margin of the third abdominal segment. 



The ground-color, as preserved upon specimens in alcohol, is yellowish 

 brown ; black dots and spots are scattered over the rudimentary elytra 

 The antennse are bluish brown; the femora and tibiae reddish,. and the 

 tarsi purplish, whilst the spines are black. 



This species differs from B. virescens by its proportionally longer an- 

 tennse, shorter pronotum, and less compressed femora. The general 

 shape of the body is in every respect proportionally longer than in the 

 latter species. 



Two specimens were collected on the *7th of July — one " green," the 

 other " reddish brown."
