THE ORDER OF COLEOPTERA. 
fFig. 9i.j insects and their larvae in the substance of l Fi g- 92 -) 
boteli or tree-fungi. The most remarkable 
character of this family, as compared with 
the Coleoptera in general, is the diminution 
in the number of the joints of the tarsi, but o^endos^ychus 8 
three joints being visible even in species of considerable 
size, with a scarcely perceptible rudiment of another joint 
at the base of the last ; all the joints except the last 
junuoauonuoi — / a 
After Kye. being dilated and cushioned beneath, and the second 
joint deeply bilobed. The antennae are usually longer than the head 
and thorax combined, and with the two or three last joints slightly en- 
larged. The thorax is almost square, and in most of the genera has a 
wide thin margin,' which is slightly turned upwards at the sides. 
A. Tarsi 3-jolnted. Length from one to two-sixths of an inch. 
B. Palpi clavate, thorax a little wider behind ; antennal club of three equal joints.. .Endomychus. 
B B. Palpi cylindrical ; thorax a little narrower behind ; antennal club indistinct, the last joint 
somewhat dilated and compressed Lycoperdina. 
A A. Tarsi 4 or 5-jointed. Length less than one-sixth of an inch. 
C. Thorax aboiit square; tarsi 4 -jointed. 
D. Anterior coxm contiguous Rhanis. 
D D. Cox® separated by the prosternum ; antennal club enormously dilated in the males: 
Phymaphora 
C C. Thorax wider than long ; size very small. 
E. Antennm II -jointed; form oval; body hairy Mycet^ea. 
EE. Antennro 10-jointed ; form globose; tarsi 5-jointed Alexia. 
Endomychus proper contains but one 1ST. A. species which closely re- 
sembles the E. coccineus of Europe. It is the E. biguttatus, Say— one- 
sixth of an inch long, black, with the elytra bright-red, with two black 
spots on each, the larger one near the tip. Lycoperdina , Latr., derived 
from Lycoperdon , a genus of fungi — contains many species which have 
been divided into several genera, or sub-genera, by more recent authors. 
The most common species is the L. vitatta, Fab., (or lineata , Olivier;) a 
quarter of an inch long, with three broad stripes on the elytra, the mid- 
dle one being common to both. The L. fcrruginea, LeO., is a little 
smaller, of a piceous or reddish-black color, with the head, legs and 
margins of the thorax and elytra brownish-red. The other genera con- 
tain but one or two species each. The two last genera are anomalous, 
and do not strictly belong in this family.

The rounded or hemispherical form of these insects, commonly known 
by the name of lady birds, and their dotted coloration, render them one 
of the most easily recognized of all the families of Coleoptera. Their
