new species of Cleridcc. 417 



duabus magnis, illo occipite nigris, pedibus nigris, tro- 

 chanteribus pallidis. 

 Long. 3 — 4 lin. 



Of the same size, and allied to the preceding, but readily 

 distinguished by the coloration of the pronotum ; the 

 scutelkim is black in two examples, but yellow in a third, 

 which is also larger, possibly indicating a sexual difference. 

 The thorax is more rounded at the side than in JlavicoUis.

Ckegya, Leconte. 



Type, C. mixtu, Lee. 



I see no sufficient grounds for separating the species in 

 this genus from Pelonium. The constriction of the pro- 

 thorax behind, and the want of serration in the anterior 

 tibiiffi, are characters found in many true Pelonia. 



Chariessa, Perty. 



Type, C. ramicornis, Perty. 



This genus is inseparable from Pelonium, excepting in 

 the form of the body, but as has been Avell remarked by 

 Lacordaire (Gen. des Col. iv. 480), the latter genus is 

 composed at first sight of most heterogeneous elements, 

 and it would be impossible to refer more species to this 

 type, without rendering the name Pelonium superfluous. 

 Chariessa has the priority by fourteen years, but as several 

 titles have been suggested for the various forms, e. g., 

 Lasiodera, Gray {Kirhiji), Philhyra, Cast, (helopioides), 

 BracliyinorpJius, Chev. ivestita). I conceive it will be 

 found simpler to reunite them under Pelonium, than to 

 refer the Pelonia all to Cliariessa, a title which has for 

 many years had a typical signification only.

 not Enoplium pilosuni, Kl. p. 113. It must be retained 

 as a Pelonium, of which indeed it formed the type.
