from the same sex of that species in the much narrower and 

 straighter tibiae, the anterior pair of which are distinctly 

 bidentate (as in T. wasmanni) ; and the acuminate apices of 

 the elytra, each of which is furnished with a single radiating 

 tuft of long stiff hairs. The strongly costate, deeply 5-sulcate 

 elytra separate it from C. simplicipes. See Wasmann, inji^a, 

 A figure of C. singalensis is included on PL V[. fig. 6.

Elongate, narrow, moderately shining, testaceous, very 

 sparsely punctate, and clothed with a few fine, short, flaves- 

 cent hairs, the basal groove of the prothoi^ax fulvo-ciliate. 

 Anterior margin of head sinuate on each side of the small 

 median tooth in (^ and obliquely directed backward from it 

 in $ . Prothorax convex, a little broader than long, with a 

 very deep, narrow median sulcus and a deep basal groove, 

 the latter extending forward along the sides to beyond the 

 middle, the margins somewhat dilated in their basal half. 

 Elytra long, oblong-oval ; each with a short humeral and 

 four dorsal sulci, the latter extending to near the tip, the 

 dividing costse convex, becoming wider and less raised 

 posteriorly, the apices somewhat produced, narrow, and 

 furnished with a tuft of stifi^, bristly, fulvous hairs. Anterior 

 tibiae bidentate ; intermediate and posterior tibiae moderately 

 broad, straight on their outer edge, slightly dilated near the 

 base within; tarsi rather slender, joint 1 of the intermediate 

 and posterior pairs about as long as 2-4 united. 



Length 3-3imm. (c^ ?.)

An immature $ in the British Museum, labelled as above, 

 is presumably referable to the species in M. Oberthiir's 

 Collection, mentioned by Dr. Gestro in his account of C. ter- 

 miticola. The mature (^ from the Nilgiris has a broader, 

 anteriorly bisinuate head. From C. tibialis, Wasm., this 

 insect may be distinguished by the less dilated anterior 

 portion of the prothorax in the ^ ; the narrower, 4-sulcate 

 elytra, with the costae less raised on the apical declivity ; 

 the much narrower intermediate and posterior tibia3, which 

 are straight on their outer edge ; and the slender tarsi. See 

 Wasmann, /'////•«, and Plate VI. fig. 7.
