 pi. 4, fig. 8. 



Sooty- black, the surface very dull and closely sculptured 

 above and beneath ; moderately elojioate, parallel-sided, the 

 legs and antenna' short, the canthus long and narrowly 

 separated from the cheek. 



9. Moderately elongate, very convex. The head is very 

 closely and rugosely juincturcd, the canthus narrow, very 

 little separated from the cheek but not laterally prominent. 

 The pronotum is strongly and closely punc^tured dcrsally, 

 densely rugose at the sides. The front angle is rather sharp, 

 the lateral margin lounded to the blunt lateral angle and 

 feebly concave to the distinct but ver}' blunt hind angle. 

 The elytra are very densely rugose, with the lateral margins 

 serrate and with uneven costse upon the anterioi' dorsal jiart. 



J. Rathei' narrow, not very convex. The head is short 

 and broad, the e])istome very short and broad, the eyes very 

 small, the sides with a very small prominence behind the eyes, 

 which does not meet the canthus. The mandibles are short, 

 strongly rounded, with a short truncate tooth placed beyond 

 the middle on the upper surface. The pronotum is short, a 

 little wider than the elytra, the sides a little rounded in front, 

 with the front angles bluntly ))roduccd, straight to the latei'ul 

 angles, which are sharji, and gently concave to the basal 

 angles, which are very blunt but well mai'ked. The clytrd, 

 are distinctly but not evenly striate, with the base, sides and 

 apices closely punctured, the striic and the inteivals very 

 irregularly ])unctured. The mentum is rugose, the prosternum 

 slightly compressed and ])ointed behind, the metastcrnvni 

 closely and coarsely granular and the abdomen closely ])unc- 

 tured. The terminal fork of the front fihia is short but sharp, 

 the middle tibia has a lati-ial s])ine and the hind tibia has non(>. 

 VaridtioH of the male. In a small specimen the head and 

 ])ronotum are closely punctured and the mandibles scarcely 

 as long as the head. Larger males have the head only finely 

 and lightly punctured and the mandibles a little longer than 

 the head.
