GROUP VIII. 
I have placed in a separate group a very small species, which differs by many charac¬ 
ters detailed below from those which precede. The body is cylindrical, the antenna) in¬ 
serted in large cavities, by which the epistoma is narrowed, but does not enlarge again 
distinctly in front as in the three preceding groups. The mouth is inferior, not applied 
to the prosternum; the front is vertical, slightly convex; the mentum large, corneous, tri¬ 
angular. The prosternum is broad, truncate both before and behind: the mesosternum 
not visible. The scutellum is triangular and small. The thorax is truncate at base. The 
legs are not contractile, the tarsi moderately short, with the membranous lobes large; the 
ungues are broadly toothed.
