32 Phytophaga Malayana. 



basal impression, smooth, impunctate. Scutellum elongate-tri- 

 gonate, closely covered with adpressed silvery hairs. Elytra 

 much broader than the thorax, oblong, subcylindrical, basilar 

 space elevated, bounded beneath by a broad shallow depression ; 

 within the humeral callus is a broad longitudinal groove ; each 

 elytron covered with eleven rows of piceous dots, the first short ; 

 it will be found on examination that a few only of these dots on 

 the basal portions of the five or six rows nearest the suture are 

 impressed each with a single fovea ; on the rest of the surface 

 these dots are smooth and impunctate ; interspaces also impunc- 

 tate ; on the hinder portion of each elytron the rows are lost in 

 the longitudinal black patch. Body beneath clothed with ad- 

 pressed silvery sericeous hairs ; hinder thighs scarcely thicker than 

 the others, extending for a short distance beyond the third seg- 

 ment of the abdomen. Mesosternal process narrow, tapering 

 from base to apex- 

 It is with great doubt that I separate this insect from C. ohll- 

 terata ; in form of antenuEe, thorax, mesosternal process and 

 in the mode of punctation of elytra, it exactly agrees with that 

 species ; in coloration it is intermediate between the type and 

 var. A ; it differs otherwise in the elytra being narrower and more 

 cylindrical above ; it is however very probable that in a series of 

 examples this character would be found to vary, in which case it 

 must be considered only a variety of obliterota.
