 cess heavy, short, extending just to interior angle of tegmen ; 

 tegmina dark brown with white spot at apical angle and with the 

 base black, coriaceous and punctate; trochanters, femora and 

 proximal ends of tibiae black; distal ends of tibiae ferruginous; 

 tarsi and claws flavous. 



Head wider than long, entirely black, finely punctate, sparsely

 conspicuous, shining, translucent, luteous, somewhat farther from 

 each other than from the eyes and situated slightly above a line

 pubescent with weak short hairs; metopidium convex, broader than 

 high, coarsely punctate; median carina strongly percurrent over

 minent, extending laterad farther than the suprahumeral horns; 

 supralrumeral horns very small and short, wider than high, flatten- 

 ed dorso-ventrally, hardly more conspicuous than a large carina 

 would be and resembling more a fold than a horn, extending out- 

 ward and upward but not reaching as far laterad as the humeral 

 angles below them, about as far, in fact, as the lateral margins of 

 the eyes and not extending much higher than the crest of the dor-
