The hind cox^e are a little longer than the 2nd ventral segment 

 and are punctured sparingly and strongly but with a defined 

 antero-internal space Isevigate, their postero-external angle rounded 

 off. The metasternum is punctured externally rather closely but 

 less strongly, in the middle more strongly and less closely. The 

 puncturation of the ventral segments is well defined but not close, 

 especially in the middle ; the ventral series consist of fine hairs 

 and are obscure. The hind femora are not much wider than the 

 intermediate, their inner apical angle feebly defined. The three 

 external teeth of the front tibise are sharp and well defined, the 

 uppermost hardly half as large as the middle one, the tibial out- 

 line from its base to the apex of the uppermost tooth being straight. 

 The basal piece of the hind claws is sharply but very minutely 

 toothed at its apex, and is a good deal longer than the apical piece. 

 The pygidium in the type is rather roughly punctured and feebly 

 carinate down the hind part of the middle ; in other examples this 

 sculpture seems much enfeebled.

The " trilobed" appearance of the head is scarcely defined ; the 

 front face of the labrum is more strongly concave than in most 

 species of the genus, owing to which, when the front outline of the 

 head is viewed from the point most favourable for observing a 

 "trilobed" appearance, the outline of the middle lobe appears 

 truncate (or almost concave) ; besides which the lateral lobes are
