back of the tarsi which are the principal characteristics in my 

 species, nor are such costse of general occurrence or of so little 

 importance that it could be supposed they had been left 

 unnoticed by Dejean from these reasons. I cannot possibly call 

 the thorax of my D. costatus " subquadratic ;" it is rounded 

 at the sides, narrowed behind, and cut away at the base. The 

 striae of the elytra of my species are not punctured in the bot- 

 tom, as those of the D. impressicollis are stated to be. In men- 

 tioning the inter-antennal impressions Dejean would certainly 

 not have overlooked the depression in the centre of the fore- 

 head nor that of the clypeus, which distinguish my insect, had 

 they existed in the one he described. The former is round : 

 the latter transverse. I further fail to discover in my species 

 the "reflet un pen changeant" of the elytra, and that the 

 base of the thorax is "assez fortement ponctuee et que les 

 points se confondent souvent ensemble;'* nor do I consider 

 the interstices of the elytra "relevh, presque arrondis," or 

 the head " un peu retre'cie poster ieurement ;" the skull is of 

 the same breadth from the antennas to the occiput.
