410 Major T. Broun on nexo Genera and 



rugosely between the eyes, with a distinct transverse 

 depression close to the front of each eye ; labrum finely 

 punctured, and bearing numerous conspicuous yellow setse ; 

 epistome medially broadly convex. Thorax deeply emargi- 

 nate in front, anterior angles blunt and extending beyond 

 the middle of eyes, evidently and widely bisinuate at base, 

 so that the subacute posterior angles appear to be directed 

 backwards and to extend over the base of the elytra just 

 •within the humeral margins ; it is slightly wider at the 

 middle than elsewhere, but without the least angulation 

 there ; the sides behind are neai'ly straight, but more, though 

 gradually, curvedly narrowed anteriorly, lateral margins 

 equally thick and a little refiexed ; there is a broad basal 

 impression at each side of the middle ; the surface is 

 moderately finely and closely punctured, less closely on the 

 middle. Scutellum simple. Elytra gradually and slightly 

 dilated towards the middle, gradually narrowed posteriorly, 

 marginal channels broad and concave, not so closely punc- 

 tured as the disk, without large impressions, and not studded 

 with granules ; disk moderately finely and closely punctured, 

 interstices smooth, much narrower and more irregular near 

 the sides, not granulate ; their costae ill-defined. 



Legs shining, dark red above, tibiae with fine yellow 

 pubescence, much more finely and not as closely sculptured 

 as those of C. opacula, and densely ciliated at the extremity 

 with short coarse fulvescent setse. 



Underside shining, rufo-piceous, finely punctate, and 

 minutely setose ; flanks of prosternum longitudinally rugose 

 and rather distantly punctured, the raised middle portion 

 finely and distantly punctured but distinctly granulate near 

 the eyes, lateral margins slightly transversely rugose ; head 

 irregularly punctate but not granulate ; femora finely but 

 not closely punctate and bearing yellow pubescence ; 

 anterior tibiae closely and coarsely punctured, the others 

 more finely. Epipleura nearly smooth before the middle, 

 feebly transversely rugose behind. 



When placed alongside my type of C. opacula it is seen 

 that this species (C. smithiana) is obviously larger; the 

 elytra are more narrowed towards the base and still more 

 evidently towards the extremity ; the ill-defined costse are 

 more distinct, the punctuation is rather deeper and coarser, 

 there are no granules or marginal foveas ; the hind angles of 

 the thorax are more protuberant behind, and it is one-fifth 

 longer in the middle. The eyes are larger. The tarsi 

 (posterior) are a third longer. The antennae are more finely 

 pubescent. The general surface less opaque.
