Phytophaga Malayann. 31 



Thorax subqiiadrate, cylindrical, nearly impunctate, being only 

 impressed here and there with a few very remote punctures. 

 Elytra much broader than the thorax, distinctly raised, basilar 

 space bounded beneath by a broad transverse depression ; surface 

 smooth and shining ; along the sutural margin, here and there on 

 the basilar space, on the transverse depression and along the 

 exterior half of the lateral border, which is also longitudinally 

 sulcate, are a number of large deep impressions, which evidently 

 form part of the rows of punctures common to the majority of 

 the species of the genus ; over the remainder of the surface these 

 punctures are entirely obliterated, their course being only indi- 

 cated by very faintly-marked longitudinal grooved lines. Ab- 

 domen smooth, sericeous ; mesosternal process narrow, tapering 

 from base to apex. 



This species, in its hairy scutellum, in the form of its antennae 

 and the puncturing of its elytra, closely approaches C. semipunc- 

 tata; it is however a much shorter and broader insect ; the an- 

 tennae are also shorter and the mesosternal process narrower ; in 

 C. sem'ipunclota this latter part is broader, and has its sides sub- 

 parallel. Var. A resembles C. semipunclata in colour, but has 

 the elytra covered with the usual number of rows of piceous dots, 

 which are smooth and impunctate, a certain number only at the 

 base, as in the type, being impressed each with a single deep fovea.

Face subelongate-trigonate, clothed with adpressed coarse hairs; 

 neck deeply constricted behind the eyes, the latter angulate- 

 emarginate ; epistome not extending upwards above the insertion 

 of the antennae, a deep longitudinal groove passing from its apex 

 to join the frontal grooves ; antennas half the length of the body, 

 robust, cylindrical, the basal joint short, rufous, the second moni- 

 liform, third, fourth and fifth each increasing both in length and 

 thickness, the remaining joints each about equal to the fifth. Tho- 

 rax cylindrical, its lateral constriction occupying about the middle 

 third of the side, anterior margin convex ; upper surface without
