 At once distinguishable from most of its allies by the total 

 absence of the two approximate tubercles that are found in so 

 many species near the summit of the jjosterior declivity of the 

 elytra, one on either side of the suture. The tubercles on the 

 elytra are all somewhat blunt and not very strongly raised, ex- 

 cept the apical two or three of the third interstice, the apical 

 one of the seventh interstice, and one at the junction of the third 

 and seventh interstices, which are proportionally about as large 

 as the corresponding tubercles in L. tribulun (male). The areola; 

 into which the elytra are divided are sharply cut and foveiform ; 

 they are many times wider and longer than the interstices that 

 limit them ; there are about twelve ai-eohe in the length of the 

 front half of the elytra.
