two of the above mentioned broken carine. This insect is 
perhaps near to 7. Brucki, Har. (which is known to me only by 
description), but cannot be identical with it since Brucki ++ 
described “processu prosternali valde tumidulo” whereas the 
prosternal process of this species is as slightly developed as in 
any 7'’rox known to me; it is angular behind but scarcely pro- 
jects beyond the general contour of the prosternum.
