Mr. Wollaston has founded tbis new genus for the recep- 

 tion of certain species of which our 3Iesites Tardii (which 

 extends to the Azores) is the type. These differ from Mesites 

 proper in being often delicately sericeous, with more approxi- 

 mated eyes, longer antennas, of which the club is much larger 

 and abrupt, and with the 3rd joint of the tarsi (minutely) 

 bilobed. 



In the male, the rostrum is considerably longer and more 

 slender, and proportionately a little more widened at the 

 insertion of the antennas, which is either at or before the 

 middle, instead of behind it. Other characters are also siven 

 by the author.

 Mr. Wollaston has pointed out that his metropolitan 

 examples representing C. linearis, Fab., are in reality to be 

 referred to the species above named; and suggests that 

 C linearis may not be British. The latter is very much 

 flatter, and more deeply and coarsely sculptured, with its 

 rostrum a little shorter, thicker, and more dilated towards 

 the tip, its scutellum distinctly larger and its tibias less 

 sinuated internally. 



C. ferrugineus appears to have a more northern range 

 than linearis, being recorded by Thomson from East Goth- 

 land and Sweden. I have not the least doubt that we do not
