and all the joints of the tarsi are alike in both sexes, elongated and 
simply pilose. 
They are peculiar to the western continent *. 
There, the hooks of the intermediate tarsi are alone unequal. 
Prircrris, Lepel. and Serv. 
The largest of these hooks and the two of the other tarsi bifid; 
first joint of the posterior tarsi very long ft. 
In the others, all the hooks of the tarsi are unequal; those of the 
two posterior ones, at least, are always eutire; one at least of the 
two or four anterior tarsi of the males, and sometimes of the females, 
is bifid.

No sternal projection; one of the hooks of the four anterior tarsi 
bifid in the males; body arched; epistoma short and transversal |}. 
Anisopiia, Meg. Dey. 
No sternal elongation ; but one of the hooks of the four anterior 
tarsi is bifid in the two sexes; the back is depressed, and the episto- 
ma usually narrowed anteriorly, and raised at its extremity § 
Lepisia, Lepel. and Serv. 
No sternal spine, but distinguished from the preceding by the four 
anterior tarsi, the hooks of which are bifid **. 
The Hoplidze or the Phyllophagi, of our third and last division 
have small depressed mandibles, as if divided longitudinally into two 
parts, the inner of which is membranous, and the other corneous; 
there are no sensible dentations at their superior extremity. The la- 
brum is concealed, or but little apparent t+. The maxille have fre- 
quently but small dentations. The body is short, depressed, and 
wide; the elytra are narrowed posteriorly on the outer side. The 
two last tarsi usually have but one hook; in those where they all 
have two—Dicrania—the first joint of the anterior tarsi is prolonged 
inferiorly, and presents on the inner side a stout, hooked tooth.
