narrowed towards the front, and is marked with a curved line on each side of the disc ; 
and the elytra are not always margined, but have at least the shoulder black. The 
Chontales specimens are all of the smallest size, the Chiriqui ones larger. 
The figure is taken from a female specimen from Chontales.

Allied to C. submarginatus; but in addition to the difference of the thoracic mark 
(which is somewhat wedge-shaped and placed in the middle of the disc, reaching 
neither the front nor hind margins), the second and third joints of the antenne are 
both very short, the third joint being only a little longer than the second, a character 
T have not observed in any of the allied species. 
I have only seen three specimens of this species.

Chauliognathus nigriceps (p. 74).

Two specimens only have been found at present of this remarkably distinct 
species. It is allied to C. emaciatus in the shape of its head, which is large, and not 
suddenly narrowed behind, with two large oblique spots on the base, partly hidden by 
the prothorax, and two large irregular but rather squarish spots between the eyes.
