sides slightly rounded, narrowly margined, posterior twice as 
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 ancl 
apex black, lower edge of the epipleuree at the shoulders fulvous.

Differs from C. circumdnctus , 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 parapleurae. 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. n. 
Eulvous ; 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.
