240 Longicornia Malay ana. 



A very distinct species, compared by M. Thomson to C. Rhetcnor, 

 Newm. 



In this and the two preceding species the transverse ridge, 

 formed by the strong constriction at the base of the prothorax, 

 has the h'ttle projecting point, found in all tlie species in the centre 

 of the ridge and therefore opposite tlie scutcllum, bifid. 



Cereopsius marmoreus. 

 Pascoe, Trans. Ent. Soc. ser. 2, iv. 105. 

 (?) Cereopsius myslkus, J. Thomson, Syst. Ceramb. p. o6fi. 

 C. sub-elongatus, niger ; elytris cinereo-marmoratis ; antennis 



rufesceiitibus, apiccm versus fuscioribus. 

 Hab. — Singapore. 



Sub-elongate, black, elytra irregularly marbled with ashy ; head 

 and prothorax with a thin ashy pubescence, the latter with five 

 callosities between the apex and the transverse ridge, which is also 

 somewhat interrupted so as to present the appearance of three 

 more callosities; scutellum triangular, ashy; elytra deeply but 

 sparingly punctured at the base, the ashy markings more or less 

 transversely zig-zag ; body beneath and legs with a thin ashy pile; 

 antennae reddish-brown, darker towards the apex. 



Length 9| lines. 



Cereopsius privotus. 



C. sub-attenuatus, fuscus, pube cervina tectus; prothorace inter 

 spinas vix elevato. 



Sab. — Malacca. 



Rather narrow, dark brown, covered with a fawn-coloured pu- 

 bescence ; head with a somewhat ashy pubescence, a few remote 

 punctures in front, lip fringed with ochreous hairs ; prothorax 

 of nearly equal breadth at the base and apex, the transverse inter- 

 spinous ridge nearly obsolete, but with a little bifid prominence 

 opposite the scutellum ; elytra obliquely lineato-pimctate, two or 

 three of the interspaces posteriorly forming slightly raised lines, 

 but uniting into one before the apex ; body beneath, legs, and an- 

 tennae with a thin ashy pile. 



Length 5 lines. 



This is rather a degraded form of the genus, but still preserving 

 all its characters, except that the disk of the prothorax is less 

 irregular. It, however, undoubtedly tends to obscure the line 

 between Cereopsius and Xoes.
