Blanchard (Hist. des Ins., ii., p. 13) gives as characters 
for Cedius :—“ Antenne with the last five joints broad 
and compressed ; tibiz slightly widened, not crenulated ; 
body oval.” It is clear, therefore, that he had some 
other genus in view. lLacordaire’s description was 
taken trom Opatrum spheroides, Hope. Plesioderes is 
probably distinct from Czdius, Lac. 
Cedius sphxroides.

In the typical examples (2) of Opatrum sphzxroides, 
Hope, in the Oxford Museum, the elytra each appear, at 
first sight, to have two rows of prominent rounded 
elevations, the inner one extending on to the base of the 
thorax : these elevations, however, are partly formed by 
dense fascicles of scaly hairs, and are not always distinct. 
Found rather commonly under stones, near the sea-shore 
(Walker).

the sea-shore. Mr. Blackburn’s specimens were obtained 
from the same locality.
