I have seen but a single specimen of this very remarkable 

 insect, which entirely recedes from the general appearance of the 

 species of "this family, and still nnore strongly than the type recalls 

 to mind the genus Lethrus. The specimen in question is certainly 

 a male, and it might perhaps, at first sight, be supposed to be the 

 opposite sex of the specimens of Col. IVestwooilil, with which we 

 are acquainted ; but the structure of the head and mandibles of 

 the latter, as well as the large pronotum, seem sufficiently to prove 

 that they also are males of a distinct species.
