NATPEAL HISTOEY OF 
and thorax are comparatively smooth. The female 
is much smaller, and the hinder thighs are not so 
thick as in the male. Like the common Cockcha- 
fer, this species lives in society, and was sometimes 
observed in great numbers by the distinguished tra- 
vellers who first brought it to Europe.

This genus includes such insects as have the hin- 
der thighs scarcely differing in the two sexes ; the 
scutellum rather small, and the pointed process of 
the sternum short, and not reaching to the insertion 
of the forelegs. The terminal joint of the maxillary 
palpus is large and ovate. The body is of an oval 
form. The species given as an illustration of this 
generic group is a native of Brazil. It is about 
eight lines and a half in length, of a fine yellow co- 
lour inclining to green. The thorax is green in the 
middle, and yellow on the sides and anterior edge. 
The elytra are thickly covered with small punctures, 
which have a tendency to form lines : the colour is 
yellow, with the region of the scutellum, and a curv- 
ed band behind the middle, green.
