Since the publication of the description ol the preceding species, 1 have been enabled 

 to examine a large series of specimens, through the kindness of Mr. Pettit of Grimsby, 

 Ontario. The males of pallidus are very distinctly bituberculate on the front between the 

 eyes, and are usually larger than their females. The he, id of the female is verj convex ill 

 ■pallidus, but in cali/ornicua there is an increase of the convexity in the place of the tuber- 

 cles of the male. The unique in the cabinet of Dr. Leconte at the time of the descrip- 

 tion of pallidus was a female, hence the failure to note the above character, which will 

 serve additionally to separate our species from the European. From the figure given bj 

 Duval, /'. testaceus is much more acute behind than either ol" our species, which are very 

 obtuse and alike in both sexes.
