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.

Seven examples — all 9'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 strise 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.
