Hiogo ; two examples. 
An elegant species, distinguished by the elytra being 
slightly dilated posteriorly. The head is long ; gradually 
elongated posteriorly. The thorax is narrow, although 
it has an explanated border of considerable width : it is 
moderately rounded anteriorly, and, behind, narrows mode- 
rately (with sinuation) to the rectangular hind angles ; the 
whole surface, except the rufous explanated margins, is 
glossy dark castaneous. The shoulders of the elytra are 
distinct, though rounded ; the strife are strongly impressed 
and distinctly punctulated. The sulci of the tarsi are 
lateral and distinctly marked only on the posterior pair.

Similar to C. lampros ; but rather larger and much 
duller in colour ; the thorax narrower and ovate, with 
naiTow explanate margins. The anterior tarsi alone have 
the 4th joint bilobed and but briefly ; in the intermediate 
it is deeply emarginated, with the exterior angle a little 
more produced than the inner one ; in the hind tarsi it is 
simply emarginated, without perceptible difference in 
length of the two sides. The species therefore approaches 
Anchomenus. The hind tarsi are grooved on the sides 
and not on the upper surface.
