206 Mr. G. R. Waterhouse's Notes 



scale-like setae: thorax thickly and rather finely punctured; elytra 

 with the punctures stronger and less thickly disposed. 



Readily distinguished from the preceding by its small size, and 

 more linear form; the puncturing of the elytra is rather less dense 

 than in Cfestivus, and the punctures are more defined, the inter- 

 vening spaces being more even ; on the other hand, the punctures 

 are stronger and more numerous than in C. pyg7nceus. 



I have taken three specimens of this insect, but omitted to re- 

 cord the localities. 



The remaining three species are destitute of pubescence or very 

 sparingly furnished, and are black, or pitchy-black in colour.

Elongate, sub-cylindrical, pitchy-black and glossy ; antennae 

 (excepting the club, which is more or less fuscous) and legs tes- 

 taceous; head rather convex, thickly punctured, with a transverse 

 depression immediately in front of the eyes: thorax fully as broad 

 as the elytra, broadly margined at the sides, and very narrowly 

 margined behind, the anterior angles nearly right angles, but 

 slightly produced; the posterior rounded, the surface rather thickly 

 punctured : elytra moderately punctured, the punctures rather less 

 thick and rather stronger than oh the thorax — under the micro- 

 scope is seen, on the hinder margin of each puncture, an exceed- 

 ingly small and short white seta. 



Length about 1^ line. 



Distinguished by its elongate form, combined with its glossy 

 pitchy black colour, and the slightly prominent anterior angles to 

 the thorax. 



I have formerly taken this insect in more than one locality, of 

 which, however, I omitted to make any notes : this year I found 

 the insect at Hawkhurst, in Kent. 



The following two species have the thorax emarginated on each 

 side in front, immediately above the anterior angle, so as to leave 

 the angle somewhat prominent and acute.
