ADDITIONS AND CORRECTIONS. 



p. 2. add ; Pubescence long and sparse, head very con-

4. Rhinomacer bombifrons, n. sp. 



Of the same form as E. pilosus, but larger, black, with a slight metallic 

 tinge, thinly pubescent with long but not coarse gray hair. Beak wider at 

 base and tip, narrowest about the middle, slightly curved, smooth above, 

 punctured at the sides, separated from the head by a very deep constriction. 

 Head nearly twice as wide as long, very convex, coarsely and densely 

 punctured ; eyes very convex and prominent. Prothorax a little wider 

 than long, rounded on the sides, strongly punctured, with a slight vestige 

 of a smooth dorsal line. Elytra strongly, but not densely punctured, more 

 finely punctured towards the tip. Antennae piceous, 3-7 joints paler. 

 Length 4 mm. ; .16 inch. 



British Columbia, one specimen. The head is also convex in R. pilosus 

 and comptus ; but to a much less extent ; the other characters are quite dif- 

 ferent and the elytra are much less densely punctured.

2. Last joint of antennae triangular pointed, as wide 



as the preceding ; black coarsely punctured, 



thinly pubescent 1. ater. 



Last joint of antennas narrower than the preceding, 



obtuse ; black finety punctured, thinly pubescent. nasalis. 



3. Bluish black, densely punctured, thinly pubescent, 2. subcceruleus. 

 Very small, brown, irregularly pubescent 3. cassandree.

 gradually wider towards the tip, scarcely punctured, with a longitudinal 

 row of punctures each side from the tip nearly to the antennae. Head
