1 am indebted to Dr. Einar Lonnberg for allowing me to tigure 

 and describe Thnnberg's type. This has cleared np some con- 

 fusion. Stul sank his Alcmena angusta as a synonym of this 

 species ; but this was a mistake, as B. spiaifex possesses two 

 spines on each pronotal lobe.

Head long, about or almost as long as the pronotum, postocular 

 portion a little longer and more slender than the anteocular 

 portion, a long obli(iue suberect spine near the antenniferous 

 tubercles ; antenme mutilated in type ; rostrum with the first joint 

 longer than the second ; pronotum subtriangular, the anterior lobe 

 obsoletely tuberculate, its anterior angles moderately prominent, its 

 posterior area profoundly and broadly suleate, posterior lobe with 

 the lateral angles longly spinously produced, between which are 

 two long, discal, tuberculous, erect spines ; abdomen long, scarcely 

 wider than the hemelytra, the fiftli segment a little dilated on 

 each side ; legs long, anterior femora a little incrassated and 

 longer than the tibitB. intermediate and posterior femora of equal
