 The two sharp tubercles on the sides of the thorax serve at 

 once to distinguish this species. The tubercle beside the eye is 

 rather large, particularly in the female ; those on the forehead 

 are small. The thorax and elytra are tuberculated rather than 

 granulated, therein differing from the typical species of the 

 genus. 



CUBICORHTNCHUS EXIMIUS. 



Oblongo-ellipticas niger cinereo-squamosus albo-vittatus, fronte 



subtiliter bituberculata inter oculos utrinque tubei-culo 



bilobato armata, thorace oblongo tuberculato lateribus 



trituberculato, elytris latis seriatim granulatis trifariam 



tuberculatis tuberculis posticis magnis conicis lateribus 



ampliatis apice dehiscentibus submucronatis.

This is a very curious insect. It has no resemblance to this 



genus except in the shape and structui^e of the head and rostram, 



which are so completely those of Cuhicorliynchus that I have 



placed it in that genus. The thorax and elytra have all the 



appearance of an Acantholoplius. The frontal tubercles are very 



minute, those near the eyes are much larger and are bilobed. 



The thorax is uneven and tuberculated, with three strong conical 



tubercles on each side. The elytra are elongate, ampliated in 



the middle, and covered with glossy looking granules disposed 



in regular rows. There are also three rows of tubercles on each
