beings separated from the base of the mandibles ; the 

 clypeus is much larger, more elongate and narrowed 

 gradually towards the apex ; the mandibles have two 

 teeth at the apex ; the eyes are distinctly margined on the 

 inner side ; the centre of the mesonotum at the base is 

 separated by deep crenulated furrows into a cone-shaped 

 lobe, the sides of the pronotum being raised at the base of 

 the furrows, which are produced as one a short distance 

 beyond the apex of the lobe ; the scutellum is narrowed 

 towards the apex, curved at the base ; the keels are 

 large and acute. The median segment is strongly and 

 uniformly transversely striated ; the centre flatly raised ; 

 the sides stoutly keeled ; the keels ending in a stout blunt 

 tooth ; the apex with an oblique slope and with the sides 

 keeled. The top and base of the mesopleurse are depressed ; 

 the edges of the depression crenulated ; in the middle and 

 reaching near to the apex is a wide, deep, slightly 

 oblique furrow ; the hinder edge has a wide, flat, slightly 

 oblique, crenulated furrow ; and, in front of this on the 

 lower side, is a short, wide, oblique depression. The legs 

 are stout ; the hinder femora have, shortly beyond the 

 middle, a short, somewhat triangular tooth ; the tibise are 

 spined, especially the hinder, the middle pair having only 

 a few and the anterior none at all ; the tarsi are spined ; 

 the claws long, curved, simple. The abdomen smooth, 

 shining and impunctate throughout ; the base oblique, 

 not hollowed ; the sides of the second and third obliquely 

 furrowed, the furrows being more distinctly defined than 

 in Pinipla. The fore tarsi are twice the length of the 

 tibiae ; the middle segments of the abdomen broader than 

 long ; the ovipo.sitor issues from a ventral cleft. 



The $ ofters no noteworthy generic character wherein 

 it difl"ers from the $.
