ponding sex of tliat insect as follows : — The head is much more 

 hollowed out down the middle, and evidently more closely and 

 finely punctured ; the prothorax is at its widest nearer to the 

 base, and its thickened lateral edging is almost obsolete ; the 

 elytra are not in the least sinuate at the apex, and the apical 

 ventral segment is very much more closely and finely punctured, 

 and its hinder portion is abruptly depressed — almost concave 

 transversely — its apex, moreover, being almost sharply truncate 

 instead of evenly rounded. (In tlie other sex of MitchelU this- 

 segment is arcuately emarginate at the apex.) In the examples- 

 before me the sanguineous lateral border of the prothorax is 

 wider than tlie pale margin in any specimen that I have seen of 

 MitcheUi.
