16 e Canadian Expedition Arctic, 1913-18 



burn point, Dolphin and Union strait, September 7, 1914; Bernard harbour, 

 Dolphin and Union strait, Northwest Territories, June 15, 2 specimens, June 

 20, 1916, 1 specimen. All collected by F. Johansen. The specimens from the 

 last two named localities have the hind angles of the thorax more obtuse and 

 perhaps represent a distinct species; some variation in this respect however 

 is noticeable among the others. 



Genus Amara Bon. 



Amara haematopa Dej. (similis Kby.) 



Bernard harbour, Northwest Territories, May 22, 1915; June 20, 1916; 

 July 9, 1916; 2cf's, 39's; F. Johansen, collector. 



Of these specimens \<? and 29 's are quite black, Id 1 metallic, the third with 

 faintly greenish elytra. The general form of body is quite like that of Pterostichus 

 agonus and it seems not to have been observed by Horn that the penultimate joint 

 of the labial palpus is bisetose in front as in Pterostichus, not plurisetose as in 

 the rest of the Amara?. 



Amara brunnipennis Dej. 



The material sent me contains ninety-three samples of this common and 

 widespread boreal species. The following localities are represented, all speci- 

 mens collected by F. Johansen unless otherwise stated. Nome, Alaska, August 

 24-25, 1916; Konganevik, Camden bay, Alaska, June 27, 1914; west of Collinson 

 point, Alaska, June 12, 1914, E. deK. Leffingwell, collector; Langton bay

 Cockburn point, Dolphin and Union strait, Northwest Territories, September 

 7 and 26, 1914; Bernard harbour, Northwest Territories, May 18-September 1, 

 1915, and 1916; Kugalik river, Wollaston peninsula, Victoria island, August 

 18, 1915, D. Jenness, collector. Probably Armstrong point, west side of Victoria 

 island, June, 1916, J. Hadley, collector. 



Amara glacialis Mann. 



Cockburn point, Dolphin and Union strait, Northwest Territories, August 

 30 and September 7, 1914, twelve tf's, eleven 9's; Bernard harbour, Northwest 

 Territories, June and July, 1915 and 1916, sixteen tf's, nine 9's; all collected by 

 F. Johansen. 



Lebia (?) sp. 



Bernard harbour, Northwest Territories, May 2, 1915, F. Johansen, collector. 

 A mere wreck with dorsum of thorax and all appendages missing. Evidently 

 found in this condition and perhaps not an inhabitant of the region explored. 

 It does not appear to be identical with any of our American species of this 

 genus, none of which have ever been reported from so far north. 



Family SILPHIDAE. 

 Genus Silpha Linn. 



Silpha lapponica Hbst. 



Konganevik, Camden bay, Alaska, July 4, 1914, F. Johansen, collector; 

 Nos. 175-6; Port Epworth, Coronation gulf, July 15, 1915 (on dried fish), 

 Nos. 123-7, J. J. O'Neill, collector; Kogluktualuk river (Tree river), Coronation 

 gulf, Northwest Territories, Julv 1915, J. J. O'Neill, collector, No. 106.
