$ . Lateribus pronoti antice paullo convergentibus, fortius denticu- 

 latis ; basi anguste et plaga media disci nitidis, sparsissime punc- 

 tatis. 



Long, rf 62, 2 68 mm. 



Hob. Cayenne (Lacordaire). 



Dark brown. Head thickly and coarsely punctured above ; 

 cheeks prominent, each projecting downwards and forwards 

 to form a rather sharp and distinct tubercle. Mandibles 

 strong, sharply curved, pointed at the apex, and each furnished 

 with two strong cutting-teeth on the inner border, one a little 

 behind the apex, the other near the base. Antennas of the 

 male scarcely reaching to the middle of the elytra ; third 

 joint half as long as the first, fourth equal to the third, the 

 succeeding joints gradually and very slightly increasing in 

 length. Pronotum of male very closely punctured, except 

 over a narrow basal area, and over two areas placed one on 

 each side of the middle ; these are sparsely punctured and 

 nitid. The lateral margins ■ of the pronotum are nearly 

 parallel, and are furnished with a series of very short teeth, 

 of which the hindmost on each side is the strongest ; between 

 the margin and the nitid area of the disk there is on each side 

 a rather distinct depression. The elytra are strongly rugose- 

 punctate. The underside of the prothorax is thickly and 

 rather strongly punctured, and is strongly convex from side 

 to side ; the flanks of the male prothorax are somewhat 

 swollen, but are scarcely visible from above ; there is no trace 

 of the suture which usually separates the episternum from 

 the prosternum. The tibiae of the two posterior pairs are 

 almost unarmed along the outer border, those of the anterior 

 pair are distinctly enough spined ; all the tibia? are produced 

 at the outer distal angle into a tolerably strong spine. 



This species, which is the Mallodon rugosum (Dupont) of 

 Dejean's Catalogue, might perhaps be regarded as the type 

 of a new genus, distinguishable from Basiioxus by having the 

 tibias all armed with a spine at the outer distal angle.

 distincteque punctatis.
