1. C. PUSILLUS Say, Trans. Amer, Philos, Soc— Since de- 

 scribed by Dejean under the name of elegantulus. 



2. C. TOMENTOSUS Say, (Epomis) Trans. Amer. Philos. Soc— 

 This species has been referred to this genus by Dejean ; the 

 palpi are not sufficiently securiform for Epomis.

 ruFous.

 nae reddish brown, three basal joints pale yellow with rufous in- 

 cisures ; labrum and mandibles honey yellow ; the latter black 

 at tip; palpi yellow ; terminal joints honey yellow; thorax deep- 

 ly punctured, sparse near the anterior angles, and almost want-
