glossy, punctured, and sparingly squamose, with the jugulura 

 chesnut-coloured. 



This species is at once distinguished from M. irrorafus by its 

 more robust form and the shorter capitulum of its antennae.

Habitat in Nova Hollandia. 



In Mus. Parry. 



Of this species I have only seen a single male individual. It is 

 slenderer in form and more elongate than C. ? mentiferus, and is 

 densely covered with minute punctures. It is black, with the 

 sides of the prothorax, elytra and legs dark brown, and the an- 

 tennae pitchy. The head is small, the anterior angles are not 

 prominent, but rounded, and the crown of the head is armed with 

 a transverse bilobed tubercle. The mandibles are porrected, 

 longer than the head, slightly curved, strongly bifid at the tip, 

 and with two small conical projections near the tips ; the upper 

 edge is compressed into an erect rounded lobe or tooth; the 

 inner margins fringed with bristles, set on transversely. 



The maxillae are minute, with the terminal lobe small, simple, 

 conical, and strongly penicillated with hairs ; the inner lobe is 

 also minute, slender, and simple. The palpi are moderately long 

 and slender, with the basal joint minute. The mentum is small, 

 transverse, flat, with the anterior lateral angles rounded off; the 

 labial palpi are slender, with the basal joint visible — they are in- 

 serted near the middle of the fore-margin of the mentum. 



The antennae are small, and the capitulum is composed of three 

 moderately long branches. The prothorax is much wider than 

 the head, transverse, with the lateral margins slightly rounded 

 and finely serrated. The anterior margin is transversely elevated, 

 and the sides are depressed within the lateral margins. The disc 

 is thickly covered with minute punctures, and there is an im- 

 pressed longitudinal line down the centre. The scutellum is 

 small and semicircular. The elytra are oblong, rounded at the 

 tip, thickly covered with small punctures, emitting fine setae, and
