episternum and reaches it scarcely in front of the middle of the 
episternum. This structure seems to associate these insects with 
Rhizobius. The genus Platyomus (as I understand it) is, then, 
distinguishable by the following characters :—Body pubescent ; 
epipleure not foveolate ; eyes not coarsely granulated nor placed 
obliquely; antenne of medium length; metasternal lamelle very 
large and of the form described above; abdominal lamelle small 
and complete; middle of prosternum forming a raised flattened 
space limited on either side by a fine carina; mesosternum large 
and conspicuous narrowed from the front hindward (its front 
margin emarginate, its surface flattened, and carinate or not) ; 
claws appendiculate (the anterior subbifid in the male). It will 
be seen from the above that the only structural characters I can 
find reliable to separate Platyomus from all the species at present 
standing in Phizobiws are the form and granulation of the eyes, 
and the sexual character of the claws.

The distinguishing characters of this species are the strong 
dilatation of the sides of its elytra behind the shoulders, the 
mixture of fine and course punctures on its elytra (in both which 
it agrees with S. Hoebelei, Blackb.) and the uniform distribution 
on the elytra of these punctures which do not become feebler or 
less deep or close towards the sides and apex. This latter char- 
acter distinguishes it from S. Koebelet, of which moreover the 
prothorax is black. The puncturation of the elytra also is 
throughout closer than S. Koebelez.
