This insect is of a very dark bronze colour. The head is 

 larger and more drooping than in the preceding species, and the 

 facial grooves are much sliorter. The thorax is considerably 

 longer than broad, with tlie sides almost parallel to near the base,

 marked in front and behind, and scarcely at all in the middle. 

 The elytra are marked with four rows of more or less thinly 

 placed depressions, each, witb one or more punctures in it. The 

 first of these rows, or that near the suture, consists of two distant 

 punctures ; the second of some seven or eight small depressions ; 

 the third of about the same number, and the fourth of five ; in 

 addition to these there ai'e lateral punctures, and the apex is 

 granulated as in the other species. The fore tibisB are distantly 

 tridentated. The mandibles are blunt at the apex. 



The specimen from wbich the above description is taken, is 

 in very bad condition, being without any vestige of antennte, palpi, 

 or even legs, excepting one fore thigh and tibia.
