Coleoptera 15 e 



Genus Asaphidion (Tachypus of our lists.) 



West of Collinson point, Alaska, June 12, 1914; F. Johansen, collector. 

 A single sample, which, judging from the description, can hardly be T. elongatus, 

 the only recorded American species. 



Genus Bembidium Latr. 

 Bembidium complanulum Mann. 

 Nome, Alaska, August 21-24, 1916. F. Johansen, collector, 1 specimen. 



Genus Pterostichus Bon. 

 Pterostichus agonus Horn. 



Seven examples — all q's — from the following localities: Konganevik, 

 Camden bay, Alaska, June 27, 1914, F. Johansen, collector; Collinson point, 

 Alaska, September 27, 1913, and June 1, 1914, F. Johansen, collector; Barter 

 island, Arctic coast of Alaska, June 11, 1914, D. Jenness, collector; Demarcation 

 point, Alaska, May 20, 1914, F. Johansen, collector; Langton bay (Franklin 

 bay), Northwest Territories, summer, 1911, V. Stefansson, collector. 



Horn's statement that the elytral striae are fine, and the intervals flat, does 

 not apply very well to any of these examples, nor to a specimen in my collection 

 taken by Dr. F. E. Blaisdell at Nome, Alaska. The unique type was from the 

 Yukon river, Alaska.

Nome, Alaska, August 21 to 24, 1916, F. Johansen, collector; Teller, Alaska,
