624 C. RITSEMA 



subsliining and sparingly punctured, and shows traces of an 

 impressed smooth line ; the granulation of the surface becomes 

 coarser towards the sides. 



The elytra, with the exception of a narrow glossy streak along 

 the suture, are opaque in consequence of the very dense line gra- 

 nulation which is however coarser on the sides of the basal half. 



The undersurface of the head and the sterna are opaque, the 

 abdomen however is glossy. The intercoxal part of the prosternimi 

 is conically porrected and, behind the coxae, compressed. The in- 

 tercoxal part of the mesosternum is furrowed along the middle. 



The anterior tibiae are nearly straight, and without any spine 

 on the outer margin. 



9 . Length 27 mm. — Black , with aeneous tinges on the 

 head, on the lateral margins of the elytra, especially at the 

 basal half, and on the epipleura, the upper side of the femora 

 yellowish red. — Above the punctuation is coarse and crowded, 

 especially on the head and pronotum ; the latter shows an in- 

 complete smooth line along the middle ; the scutellum is smootli 

 with a few punctures at the base ; along the suture the punctures 

 are a trifle smaller and wider apart than on the rest of the 

 elytra which are without any trace of costae. — Underneath 

 the punctures are widely spread on the metasternum, but rather 

 close together on the abdomen. 



The clypeus is protruding and broadly, rounded anteriorly; 

 the tip of the mandibles, which latter are deeply furrowed on 

 the outside , is bifid , the inner lower margin of the left man- 

 dible provided with a stout tooth, that of the right mandible 

 with a minute one. 



At the middle of the lateral margins of the prothorax a very 

 distinct tooth is present. 



The anterior tibiae are armed with three strong acute spines 

 before the apical one ; the intermediate tibiae have behind the 

 middle two spines which are very close together (one large, 

 the other small) and the posterior tibiae one strong spine behind 

 the middle.
