narrowed anteriorly) than the C. fuscipes, dark brownish black, 

 and clothed throughout with short, suberect, and rigid cinereous 

 setaa. Head obtusely rounded (or subtruncated) anteriorly, and 

 distinctly bitubercled in the males. Prothorax about (or per- 

 haps scarcely) as broad as the elytra, with the sides, as well as 

 the anterior and posterior angles, more rounded than in the 

 C. fuscipes, a little more regularly produced in front from each 

 anterior angle (which causes the latter to be obtusely rounded 

 off, instead of being a little prominent as in that insect) ; sub- 

 opake and (beneath the microscope) most minutely alutaceous, 

 and regularly and rather densely punctured, the punctures being 

 smaller and deeper than those of the C. fuscipes, as well as more 

 regular and better defined (being all equal, and not composed of a 

 double set as in that species) ; the lateral edges margined, but 

 not so broadly as in the C. fuscipes, but the hinder one per- 

 haps rather more evidently (though, at the same time, very deli- 

 cately); and with the faintest possible indication of a dorsal 

 line, which tends to become a keel behind, but a channel in 

 front. Elytra rather less opake than the prothorax, and not 

 appearing alutaceous when viewed beneath the microscope ; also 

 rather more uneven or rugulose, though less so than in the C. 

 fuscipes ', more closely and deeply punctured than in that insect, 

 but with the same double system of punctures, the larger ones of 

 which have, like the pubescence, a tendency to be disposed in 

 longitudinal rows. Limbs rufo-testaceous. 



Apart from the many characters to be gathered from the above 

 diagnosis, the present Cis, several specimens of which were cap- 

 tured by Mr. Bewicke on the trunk of a decayed Spanish chest- 

 nut-tree at the Mount, above Funchal, may be known from its 

 Madeiran ally, the C. fuscipes, by its smaller size, darker hue, 

 and shorter seta3, as well as by its somewhat narrower and less 

 margined prothorax, and its different sculpture.
