86 INSECTA. 



The tarsi of all the others are furnished with a brush, and the 

 penultimate joint is deeply bilobate. 



Some are pi'ovided with wings. 



Here the lateral sulci of the proboscis are oblique and directed 

 inferiorly. The anterior legs differ but little in their proportions 

 from the following ones. They form a first subgenus, that of 



CvviCVLio, proper *. 

 Which comprises a great number of the genera of Messrs. Germar 

 and Schoenherr, the characters of which are of but little importance 

 and frequently very equivocal. At most, we can only detach those 

 whose antenna are proportionally longer. 



Among those in which the antennae are short, the thorax is longi- 

 tudinal and forms a truncated cone, the shoulders are salient, and of 

 which the genera Entimus, Chlorima, &c. have been formed, come 

 certain species from South America, remarkable for their splendour 

 and frequently for their size. 



C.imperialis, Fab.; Oliv., Col. V, 83, i, 1. A brilliant gol- 

 den-green with two black and longitudinal bands on the tlio- 

 rax; ranges of golden-green impressed points on the elytra, 

 with black intervals. 



C. regalis, L. ; Oliv., Ibid. I, 8, A blue-green, with very 

 brilliant cupreous or golden bands on the elytra. It is found in 

 St. Domingo and Cuba. 



The name oi fastuosus, nobilis, &c. given to other species, in- 

 dicates the magnificence of their attire. 



One of those that inhabit France, which is most analogous to 

 the preceding, is the C. viridis ; Chlorima viridis, Dej. ; Curcu- 

 lio viridis, Oliv., Ib„ ii, II, It is about five lines in length ; the 

 first joint of the antennse is proportionally shorter than in the 

 preceding species ; obscure-green above; sides and inferior parts 

 yellow ; the termination of the elytra is somewhat pointed ; the 

 proboscis is carinated. Very rare in the environs of Paris. 



Some others, also inhabiting the same country, arranged by 

 Schoenherr in the genus Polydrosus sericeus, Gyll., micans, be- 



* 1. Thorax lobate anteriorly. 



The genera Entimus, Rhigus, Promecops Phcedropus, Dereodus (subgenus of Hypo- 

 meces, Polydivs, Entyus of Schoenherr, and the Brachysonia of Dejean, but reduced 

 to the species which he calls the suiuruUs, 



2. Thorax non-lobate anteriorly. 



* Thorax sensibly longer than it is wide. 



* Proboscis shorter than the head, or at most of equal length. 



The genera Clorophcmxis, Ithycerus, Anmncrus, Hypomeces, Anymecus, Asfycus, Lis- 

 sorhinus, Prostenomus?, Ai-tipus, Sifona, of Schoenherr. 



** Proboscis evidently longer than the head. 



The genera Hadropus, Cyphus, Callizonus. 



** Thorax transversal, almost isometrical. 



The genera Eustalcs, E.ropfhabnus Biaprepes, Ptilopus, Pacnaus, Polydrosus, Metal- 

 lites. The relative length of the first joint of the anteunafe also furnishes good cha- 

 racters, which might be employed before resorting to those drawn from the thorax.
