86 INSECTA. 
The tarsi of all the others are furnished with a brush, and the 
penultimate joint is deeply bilobate. 
Some are provided 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 forma first subgenus, that of 
Curcu.io, proper *. 
Which comprises a great number of the genera of Messrs. Germar 
and Scheenherr, the characters of which are of but little importance 
and frequently very equivocal. At most, we can only detach those 
whose antennz are proportionally longer. 
Among those in which the antennz 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, 83,1, 1. <A brilliant gol- 
den-green with two black and longitudinal bands on the tho- 
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 of fastwosus, 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, De}. ; Curcu- 
lio viridis, Oliv., Ib,,ii, 11. It is about five lines in length; the 
first joint of the antennz 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 
Schoeenherr in the genus P olydrosus sericeus, Gyll., micans, be- 
* 1. Thorax lobate anteriorly. 
The genera Entimus, Rhigus, Promecops Phedropus, Dereodus (subgenus of Hypo- 
meces, Polydius, Entyus of Scheenherr, and the Brachysoma of Dejean, but reduced 
to the species which he calls the suturalis. 
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 Clorophanus, Ithycerus, Anemerus, Hypomeces, Anymecus, Astycus, Lis- 
sorhinus, Prostenomus?, Artipus, Sitona, of Schceenherr. 
** Proboscis evidently longer than the head. 
The genera Hadropus, Cyphus, Callizonus. 
** Thorax transversal, almost isometrical. 
The genera Eustales, Exopthalmus Diaprepes, Ptilopus, Pacneus, Polydrosus, Metal- 
lites. ‘The relative length of the first joint of the antenne also furnishes good cha- 
racters, which might be employed before resorting to those drawn from the thorax.
