The size is larger than that of y. in</rii'eiiiris, the head is larger 

 and wider across apex, the prothor-ax has tiie sides more suddenly and 

 angularly inflated, and its medio-basal fovea and the elytral striae 

 are deeper. From l)oth sexes of .V. raria it is readily distinguished 

 by the sides of the prothorax. 



On the whole of the ui)i)er surface there are more or less dense 

 punctures, but these are more or less concealed until the clothing has 

 been abraded. From some directiims the sides of the elytra towards 

 the apex appear to be feebly notched.

Head wide ; with two large Init ratlier shallow inter-ocular foveae. 

 Antennae coni]>aratively short, second joint slightly stouter than tirst 

 and, t'loui above, ajipaiently slightly longer, third to seventh small,

 wide towards Ijase, and elsewhere very narr(nv l)ut clearly defined. 

 Under surface of fourth segment of (d)iUumii with a shallow sub-

 others each of its walls appears to be tipped by a minute tubercle.
