of ten joints. All the hooks of the tarsi, with the exception of the 
anterior, are unequal; the strongest of the intermediaries is entire in 
the male; the others, and the six in the females, are bifid. The body 
is covered with little scales. 
But few species are known, and all of them are from Bra-

Areropes, Leach, Mac L., 
Have ten joints in the antennz, a corneous sternum, and all the 
hooks of the tarsi equal in the individuals presumed to be females— 
Lepel. and Serv.—and unequal in the males; the thickest of the two 
anterior ones of the latter is bifid, and all the others are entire. 
The colours of these Insects are very brilliant }. 
In all the preceding Phyllophagi, with some few exceptions, we 
have found the antennze to consist of ten joints. In all the following 
ones of the same division, or that of the Melolonthide, we shall find 
but nine. 
Here all the hooks of the tarsi are equal; one of the two anterior 
ones, at most, is sometimes larger.

Hooks of the anterior tarsi, at least in the males, bifid; and the 
others entire f.

frequently with changeable reflections; thorax much wider than

Dipnucepuata, De). 
Here also all the hooks of the tarsi are bifid; but the body is nar- 
row and elongated, and the thorax almost square. The first joints 
of the four (male) or two (female) anterior tarsi are short, and pro- 
vided with brushes underneath; the same joints are dilated, or wider 
in the four first tarsi of the males. The epistoma is strongly and an- 
gularly emarginated. 
These Insects are peculiar to New Holland §.
