their apical membrane well defined. The puncturation (except on 

 the head) is neither strong nor close, a little stronger and less 

 close on the prothorax than on the elytra ; on the prothorax the 

 punctures are spaced so that about 17 of average distance apart 

 would lie down the middle line. On the underside the hind coxse 

 are much shorter than the metasternum but not ve'ry much longer 

 than the 2nd ventral segment ; the metasternum is rather finely 

 and sparingly punctured, the hind coxae more coarsely, but with 

 a well defined Isevigate antero-internal space. The ventral seg- 

 ments are rather coarsely punctured, the ventral series consisting 

 of fine hairs and being inconspicuous. The hind femora are 

 moderately wider than the intermediate, their inner apical angle 

 feeble. The hind claws are appendiculate, the basal piece not 

 much longer than the apical and having its inner apical angle 

 fairly defined and sharp. The front tibiee have three rather blunt 

 external teeth, the uppermost being especially blunt and scarcely 

 half as long as the 2nd. 



In the tabulation (Proc. L.S. N.S.W. 1888) this species would 

 fall under " D " (at bottom of p. 1329) ; from piceus and Froggatti 

 it differs iiiter alia in the free outline of the clypeus not forming 

 an even curve ', from occidentalis in the same being feebly sinuate, 

 not strongly emarginate.
