(J. Form rather elongate, robust ; black, smooth ; head small ; 

 prothorax depressed, broader than long, rounded on sides, without

 narrowed to base. 



Head small (3"25 x 4-75 mm.), depressed, lightly transversely 

 impressed behind; frontal sulci very strongly impressed, diverging 

 in a rather sinuous course backwards, curving lightly out in front 

 in a well-marked course ; pre-ocular sulcus strongly marked, curv- 

 ing inwards ; pre-ocular process prominent, projecting roundly ; 

 eyes round, rather prominent, projecting but little beyond the 

 piv-ocular processes; suborbital channel divided by a longitudinal 

 ridge, the lower branch dividing the genee from the guise ; three 

 supra-orbital punctures on each side. Mandibles short. Mentum 

 with lobes long, narrow ; median tooth strong, pointed, nearly

 obtuse ; second joint short, not longer than third. Prothorax 

 broader than long (6x7 mm.), depressed ; sides rounded, widest 

 about middle, roundly narrowed behind ; a light short sinuosity 

 near each basal angle behind the lateral border ; anterior margin 

 truncate, hardly emarginate ; anterior angles broadly rounded, 

 not advanced ; posterior angles not marked ; base wide, not 

 bordered, rounded in middle, with an obsolete sinuosity towards 

 each side ; lateral borders thick, not reflexed, extending round 

 anterior angles, not reaching the base ; marginal channel narrow
