COLEOPTERA. 57) 
which the club of the antennz is formed by the last five joints, and 
the preceding ones are slightly securiform *. 
Those, in which the three last alone form the club, and the three 
preceding ones, are in the form of reversed cones without an inte- 
rior projection, compose the genus CoxEtus f. 
Our second tribe of the Taxicornes, the CossyPHENEs, consists of 
Insects analogous in form to the Pelt’s of Fabricius, and to several 
Nitidulee and Cassidiz ; it is ovoid or sub-hemispherical, and over- 
lapped in its contour by the dilated or flattened sides of the thorax 
and elytra; the head is sometimes entirely concealed under that tho- 
rax, and at others received into an interior emargination of the same 
part. The last joint of the maxillary palpi is larger than the pre- 
ceding ones, and securiform. 
This tribe is composed of the genus 
Cossypuus, Oliv. Fab. 
Some of them have a flat body, of a solid consistence, in the form of 
a shield, and antennz terminated by a club composed of four or five 
joints ; they are peculiar to the eastern continent and to New Hol- 
land. Such are those which form the 
Cossypuus, Oliv. Fab. 
Or Cossyphus properly so called, where the almost semicircular 
thorax presents no anterior emargination, and entirely conceals the 
head; where the antenne are short, and terminate abruptly in an 
oval mass of four joints, most of which are transversal; the second 
of the whole number and the following ones are almost identical. 
These Insects inhabit the East Indies, southern part of Europe, 
and north of Africat. In

The head is received into a deep emargination or median aperture 
of the thorax, and is exposed at least superiorly. The antenne, at 
least as long as these two parts of the body taken together, termi- 
nate almost gradually in a narrow, elongated club, formed by the 
last five joints, the last of which is ovoid, and the preceding ones 
turbiniform ; the second of the whole number is shorter than the 
third.—They are peculiar to New Holland §. 
The others, where the head is always exposed and simply received 
into a deep notch in the thorax, have a convex, soft or but slightly 
solid, almost hemispherical body, and granose antenne, nearly equal

these Insects.
