known not only by the particulars before noticed, but also by its 
transverse labrum, its entire and very concave maxilla, and by 
the elytra covering all the joints of the upper side of the abdomen 
butthelast; whereas in Apogonia the two last joints are uncovered. 
Geniates may be distinguished from Apogonia not only by this 
last circumstance, in which it agrees with Anoplognathus, but also 
by having a transverse labrum, maxillae armed with three teeth, 
by the insertion of its head, which is inclined towards the horizon, 
whereas in Apogonia it is nearly vertical, by having a joint less in 
its antennæ, by the beard on its chin, and remarkable dilated 
anterior tarsi before noticed, by having only its exterior claw, and 
not both, hifid at the apex; and lastly, by the remarkable thumb- 
like process at the base of the inner anterior claw.
