Although I have before me only a single individual, and that is extremely similar to 
C. incognitus, yet I believe it indicates a distinct species ; for it is decidedly smaller and 
has a basal fascia on the wing-cases, the sexual sculpture is a little finer, and near the 
apex only five striz are to be detected; it should be noted that on the middle of the 
elytra there are, on a critical examination, to be detected five other striz, representing 
the alternate strie of such species as have ten strie; and it is possible that the male 
may prove to have ten strie on the elytra. These alternate obsolete or rudimentary 
strie are formed by the joining together in one line of the fine sexual scratches or 
sculpture.

Hab. Mnxico, Cordova (Sallé). 
Head red, on the vertex with very fine sculpture. Thorax reddish on the sides, 
broadly infuscate on the middle, closely covered with elongate scratches or striole, 
which, however, are not connected together so as to form any distinct network. Elytra 
closely covered from the side margin to the suture with elongate rather deep striole ; 
although these scratches are elongate and rather irregular in their direction, so that 
they appear to form an irregular network of elongate meshes, yet very few of them are 
actually connected with one another; a rather broad space at the extremity is smooth; 
on the apical portion six fine striz may be distinguished, and on a very careful exami- 
nation they may be traced forwards, or at any rate one or two of them, to near the base. 
The submarginal stria is short and indistinct, and may easily escape detection.
