Scydmenus castaneus, Woll. [nee Schm. 1841], Col. 
Atl. 449 (1865). Scydmenus castanicolor, Har., Col.

Cephennium mycetceoides, n. sp. 
C. elongatulum, obovato-ellipticum, nitidulum, omnino 
(palpis tarsisque testaceis exceptis) pallide rufo-ferrugi- 
neum et grosse fulvo-cinereo pubescens, parum dense sed 
minute (in elytris distinctior) punctulatum ; prothorace
