116 CANAEIAN COLEOPTERA. 



the second of the Cyhocephali here enimciated from the first; but 

 (apart from its purely specific characters alluded to in the diagnosis) 

 the less truncated apical joint, also, of its antennae ^ill still further 

 remove that species from the C. sjplicerula (which is, in all respects, 

 a normal representative of its group). Nevertheless in eveiything 

 essential the C. Icevis is an undoubted Cyhoceplialus, and cannot ]30s- 

 sibly be treated as anything but congeneric with the other. 



As I was of course unaware when I pubHshed my Stagonomorplia 

 that it was identical with Cyhocepludus, it never occiu-red to me to 

 refer at all to the diagnosis of the latter ; and it is therefore worth 

 observing that I should unintentionally have fully corroborated the 

 after-remark of M. Jacq. Duval, that the tarsi of this genus are 

 strictly tetramerous, and that consequently Erichson was mistaken in 

 supposing that there existed a minute fourth joint concealed between 

 the lobes of the deeply cordate third one. I examined the feet of 

 Stagonomorpha , at the time, with great care, and completely satisfied 

 myself that there was no such additional articulation ; and I am con- 

 vinced therefore that M. Duval is perfectly correct in his statement 

 on this point.

The present Cyhocepludvs, which appears to be identical with the 

 species which I described from Madeira in 1854, differs, inter alia, 

 from the European exiguus in being smaller, in having the hinder 

 margin of its prothorax more sinuated or concave (causing the pos- 

 terior angles to appear less rounded oflp), and in its surface, when 

 viewed beneath the microscope, being much more coarsely alutaceous 

 and with the (very remote) punctures relatively more evident. It
