8 INSECTA. 
Sometimes there are two hooks to all the tarsi. The antenne 
never have more than nine joints. The epistoma is usually trans- 
versal. The palpi are but slightly elongated, and their last Joint is 
oval. 
Here; the posterior legs differ but little from the others. 
CuasmorTerus, De) —Metotontna, L/lig. 
All the hooks of the tarsi bifid; terminal lobe of the maxille nar- 
row, elongated, with two remote teeth on the inner margin; the body 
almost oval, thorax rounded, and the elytra of equal width through- 
out *. 
CuasmeE, Lepel. and Serv. 
The Chasmes only seem to differ from the preceding Insects in 
the hooks of the two posterior tarsi, the largest of which is alone 
bifid +. 
There, the posterior thighs, at least in the males, are very large 
and dentated, their tibize thick, and terminated by a strong hook. 
DicueExes, Lepel. and Serv—Mexotontnaa, Fab. Oliv. 
The body is short, but slightly pilose, and the elytra are narrowed 
towards the extremity, forming an elongated triangle. The poste- 
rior legs are partly contractile. All the hooks of the tarsi are equal 
and bifid. The terminal lobe of the maxille is dentated along its 
inner margin, as in Hoplia, to which this subgenus closely ap- 
proaches f. 
Sometimes the two posterior tarsi have but a single hook—those of 
the others are unequal and bifid. 
Some, like the preceding, have but nine joints in the antenne. 
Lepirrix, Lepel. and Serv.—Tricuius, MeLotontua, Fab. 
The body short; thorax narrower than the abdomen, nearly square, 
and slightly narrowed posteriorly ; abdomen broad and posterior legs 
large; last joint of the maxillary palpi much longer than in the pre- 
ceding subgenera; terminal lobe of the maxillee very small and in the 
form of a short triangle §. 
The others have ten joints in their antenne. 
_ Fhe body is short and densely pilose; the epistoma forms an elon- 
are4 triangle, truncated or very obtuse at the end; the salient palpi 
long, nimated by a long and cylindrical joint; the maxillary lobe is 
abdomen laig salient at the extremity and destitute of teeth; the 
~nd the posterior legs long. 
Pacuycnemus, Le, , 
The elytra narrowed and Serv.—MELOLoNTHA, Tricuivs, Fab. 
two posterior legs inflated, ¢fheir extremity, thighs and tibie of the 
q 
two extreme spurs much stouteste? almost clavate, with one of the 
2n the other.
