NATURAL HISTORY OF 
The genus Geotrupes* has antennae with the 
three last joints dilated and transverse, forming a 
lamellate club, as in the following figure. The 
mandibles stand out from the head, 
an ^ are notc h e( l at the apex. The 
eyes are divided by the margin of 
A the head, and touch the thorax. The 
Aj latter is as broad as the elytra, and 
very convex. The elytra are short 
and oval. Ten different kinds are 
met with in Britain. That repre- 
sented is the most common in the northern parts ot 
this country ; it is named 
GEOTRUPES STERCORARIUS.

It is entirely black above, tinted on the margins 
with violet or brassy : the thorax is without punc- 
tures on the disk, but has a few impressed points 
towards the sides, and a short line in the middle 
behind. The elytra are marked with deep striae, 
the spaces between w T hich are smooth and somewhat 
convex. The under side and legs are steel blue, 
glossed with purple or green in a very beautiful 
manner.
