34 Phytophaga Malayana. 



Head deeply constricted behind the eyes, face triangular, front 

 remotely punctured ; antennae shorter than half the length of the 

 body, subincrassate, outer joints slightly compressed and subper- 

 foliate, eyes notched. Thorax subquadrate, scarcely broader 

 than long ; sides constricted in the middle ; above subcylindrical, 

 punctured as is C. impressa, the single longitudinal row of punc- 

 tures down the middle of the disc being also present as in that 

 species. Elytra oblong, much broader than the thorax, slightly 

 dilated behind, their apex broadly rounded ; above convex, indis- 

 tinctly flattened along the back, transverse depression below the 

 basilar space usually obsolete, at other times present, although 

 indistinct ; punctures arranged in eleven longitudinal rows, the 

 first of which is very short ; the punctures are large, deeply im- 

 pressed, and placed at irregular intervals on the anterior half of 

 the rows ; on the hinder half they become much smaller and indis- 

 tinct, the rows themselves being frequently entirely obsolete ; the 

 inner row next the suture is however always sulcateon the hinder 

 portion of its course, and, together with one or two of the outer 

 striae, remains always entire ; interspaces smooth, impunctate. 

 The amount of fulvous colour on the surface varies greatly ; in 

 some specimens, the black ground occupies almost entirely the 

 posterior three-fourths of the surface, the basal fourth, and a 

 narrow line extending round the outer limb, alone being fulvous ; 

 in others the fulvous colour is extended inwards so greatly in all 

 directions (more especially however at the base and apex) as to 

 leave only a common central black patch. Under surface clothed 

 as in C. impressa, but the sericeous patches on the surface of the 

 alidomen are less strongly defined. Very closely allied to C. im- 

 pressa ; setting aside colour, the only difference between the two 

 species is in the form of the process of the mesosternum ; in C. 

 impressa this part is oblong-quadrate, with its apex broadly trun- 

 cate ; in C. Clarkii it is subtrigonate, with its apex obtusely truncate.
