This species is at once distinguishable from all the preceding 



species of Leptojis (apart from its diminuti^-e size) by its having, 



like L. tribulun, three series of tubercles on each elytron, none of 



which become simple carina; near the base. Tt resembles several 



of Schonherr's species of Leptojjs, from which it diiFers inter alia 



as follows : — From dumosus by the unusually elongate median 



carina of the rostrum, and by there not being on each elytron 



three exceptionally large tubercles placed triangularly ; from 



hysiricosus and spinosus by its wide, deep, and entire prothoracic 



channel ; from spi'iiiger by the absence of an isolated strong spine 



near the shoulders.
