Of the species above enumerated several are still unknown to 

 me in nature, and a complete solution of the question of specific 

 rank of some others must be left for future investigation, when 

 the criteria for estimating introspecific variability can be de- 

 tei'mined with some slight degree of certainty, these remarks ap- 

 plying more especially to the forms in the neighborhood of sculp- 

 tipennis and dissolutus."^

Moderately stout and ventricose, shining, the elytra minutely 

 reticulate and somewhat alutaceous. Head elongate, rather broad, 

 the upper surface strongly and longitudinally carinate, with a
