Others have the body ovoid, short, strongly inflated above, with 
the circumference of the abdomen clasped by the elytra. The thighs 
are canaliculate, and receive the tibiz in their sulcus. Their eyes are 
large. ‘The antennz always consist of twelve joints.

Others, with an oblong, convex body, and the anterior legs usually 
longer, particularly in the males, with antenne consisting of twelve 
joints, the eyes remote, and elytra covering the abdomen, will form 
the subgenus 
CrYPTORHYNCHUs ¢. 
Those which are apterous, or where the wings are at least very 
imperfect, and the scutellum is wanting, will form another, or

M. Chevrolat has discovered one species—Rhynchenus plinoides, 
Gyll.—in the vicinity of Paris. 
The remaining Longirostres have generally nine joints at most in 
the antennz, and the last, or*two last at most, form a club witha 
coriaceous epidermis and spongy extremity. They feed, at least 
while in the state of larvae, on seeds or ligneous substances, 
They may be united in the single genus 
CALANDRA, 
Which may be divided into six subgenera. 
The two first are apterous, and ‘present, as well as the preceding 
and following ones, the last excepted, four joints in all the tarsi, and 
of which the penultimate is bilobate. The antenne are geniculate 
and inserted at but a little distance from the middle of the proboscis. 
In the first or 
Ancuonus, Schenh., 
These organs present nine joints before the club. The tenth, and 
perhaps two others, but intimately united with the preceding one, 
and but little distinct, form a short ovoid club.

} The genera 4rthosternus, Pinarus, Cratosomus, Macromerus, Cryptorhynchus 
of Schenherr, The Gusterocerus of Messrs. Brullé and Laporte appears to me to 
belong to the Cratfosomus proper of Schcenherr, or those in which the proboscis is 
straight and flattened. His subgenus Gorgus is composed of large species, all from 
South America, and in the males of which the probiscis is usually armed with two 
teeth or horns near the insertion of the antenne. I could not find any dentation in 
the mandibles, one of the characters which distinguish the Cratosomi from the 
Cryptorhynchi, where these organs are dentated,
