sides slightly rounded, narrowly margined, posterior twice -us 

 broad as the anterior margin ; surface impunctate, margins pale : 

 disc fulvous, with two widely separated black spots placed rather 

 nearer to the anterior than to the posterior margin. Scutellum 

 flavous, margined with black. Elytra strongly and closely punctate- 

 striate, punctures finer near apex, basal portion not depressed, 

 interstices sparingly punctured on the anterior portion, sides and 

 apex black, lower edge of the epipleurae at the shoulders fulvous.

Length 2-3 mm.

Differs from C. rircumductus, Suffr. in the different colour of the 

 antennae and the absence of elytral wrinkled interstices. Black 

 varieties of C. parasiticus can be distinguished by the distinctly 

 punctured thorax and the fulvous elytral parapleuraa. C. angusto- 

 marginatus, Jac. also closely resembles the present species "but is 

 larger, the head is strongly punctured, the elytra finely punctate, 

 the underside is flavous and the tarsi are black. 



Elytra black, with pale spots. 



341. Cryptocephalus assamensis, sp. u. 



Fulvous ; base of head and apical joints of antennae black ; 

 thorax with two elongate black spots ; elytra black, a small spot 

 near scutellum and a large spot at middle of disc flavous. 



Head strongly punctured, middle portion flavous, sides and 

 vertex black ; clypeus strongly punctured, feebly separated, 

 anterior angles pointed ; antennae short, basal five joints fulvous, 

 rest black, sixth and following three joints widened, rest wanting 

 in the type and only specimen. Thorax twice as broad as long, 

 lateral margins rounded ; surface nearly impunctate, a short oblique 

 depression at base on each side in front of scutellum ; disc with two 

 large round black spots near middle, extending to base as a narrow 

 stripe. Scutellum broad, black. Elytra short and broad, finely 

 punctate-striate, interstices flat and impunctate, basal spot sub- 

 triangular, discoidal spot large and round, not extending to either 

 margin and placed at some distance from apex. Prosternum broadly 

 produced anteriorly into a hollow projection ; tarsi piceous. 



Length 4 mm.
