 This curious species, which was unique in the Sall6 

 collection, has heen taken in some numbers by Herr 

 Huge at Acapulco. In all the examples the joints 3—5 

 of the antennae, except the black apical brush on the 

 5th, the base of the femora, and tibite, are testaceous- 

 red.

A good series of examples. In form the species is like 

 a small and slightly built C. sthenkis, Bates, or C, 

 houchardi, Pascoe; but it differs from the group to 

 which these belong by the aeneous abdomen.
