FAMILY II. 
—_——+———. 
APHIDIPHAGI. 
This family consists mostly of Insects which have an almost hemis- 
pherical body, and a very short, transversal, and almost lunate thorax. 
Their antennz terminate in a compressed and obconical club, com- 
posed by the three last joints, and are shorter than the thorax. The 
last joint of the maxillary palpi is very large and securiform, and the 
penultimate joint of the tarsi is profoundly bilobate. 
In the other Trimera of the same family, the joints of the tarsi are 
simple, and the penultimate at least is slightly bifid, which, with some 
other characters, distinguishes these Insects from the Fungicole. 
Here, the body is more or less thick, and never much flattened in 
the manner of a shield; the thorax is transversal; the head is ex- 
posed ; the antennve consist of eleven distinct joints, the last of which 
form an obconical club. 
These Insects compose the genus 
COccCINELLA. 
Lirnoruius, Frohl. 
Where the body is ovoid, the thorax strongly recurved laterally, 
and narrowed posteriorly, and the penultimate joint of the tarsi, as 
well as the preceding one, is very slightly bifid +. In 
Coccineia, Lin. Geoff. Fab. Oliv., 
Or Coccinella proper, the body is almost hemispherical, the thorax 
very short, almost lunate, the margin not recurved or but very 
slightly, and the penultimate joint of the tarsi profoundly bilobate. 
Various species of this genus are extremely common on the 
trees and plants of our gardens, and frequently in our houses ; 
they are known by the names of the Scarabées hemispheriques or 
Tortues, Béte & Dieu, Vache a Dieu, Cow-bug, Lady-bug, &c. 
The figure of these Insects, which is frequently hemispherical, 
the number and arrangement of the spots on their elytra, that 
form a sort of mosaick on a fulvous, yellow or black ground, to- 
gether with the vivacity of their motions, render them easily dis- 
tinguishable. They are among the first that appear in spring. 
When seized, they fold their legs against their body, and like

+ Lithophilus ruficollis, Dahl, Catal., p. 44; Tritoma connatum, Fab. This genus 
would, perhaps, be placed more naturally near Triplax, Fab.; but in the antenne it 
also approaches the Coccinelle, Count Dejean arranges it among the Heteromera,
