Agroperina lateritia Hufn. 



Phalaena lateritia Hufn.: Berl. Mag., Ill, 206, 1707. 



I have recently received a single worn specimen of this common and wide- 

 spread species from Rev. C. E. Whittaker. The specimen was collected ;it 

 Whitehorse, Yukon Territory. 



Genus Autographa Hhn. 

 Autographa sackeni Grt.? 



Plusia sackeni Grt.: Can. Ent., IX, 135. 



In the Entomological Record for 1904 1 we recorded this species from Mayo 

 lake, Yukon Territory, August 7, 1904 (J. Keele). 



I submitted this specimen to Dr. R. Ottolengui, and he has kindly studied 

 it and reported that he is practically certain it is sackeni. The species was 

 described from Idaho Springs, Colorado, so its occurrence in the Yukon is 

 noteworthy. Dr. Ottolengui states 2 : " I have never before seen sackeni from 

 any section except Colorado. However (unlike vaccinii which is found nowhere 

 except on Mount Washington) sackeni has been taken on several of the mountains 

 in Colorado." 



I cannot, however, agree with Dr. Ottolengui in the above determination. 

 A. sackeni, according to the description, should have a distinct golden-yellow 

 patch on the costa, near the base of the wing, described by the author of the 

 species as an " interior golden patch." This character is entirely absent in the 

 specimen under discussion from Mayo lake, and I am inclined to think that it 

 will ultimately prove to be of a species which is at present undescribed. The 

 specimen is figured on PI. Ill, fig. 14. 



Autographa altera Ottol. ? 



Autographa altera Ottol.: Jour. N.Y. Ent. Soc, X, 69, 1902. 



One male specimen taken at Bernard harbour, Northwest Territories, 

 August 25, 1915 (F. Johansen). 



Unfortunately the specimen is in rather poor condition and it is difficult to 

 definitely determine it. I referred it to Dr. Ottolengui who would not name 

 it otherwise than altera? The specimen is shown on PI. Ill, fig. 13. 



FAMILY LYMANTRIIDAE. 

 Genus Gynaephora Hbn. 

 Gynaephora rossi Curtis. 



Laria rossii Curtis: Ross* Second Voyage X.-VV. Pass, App., 70. 18:-!">. 



Ten adult specimens, six males and four females from Demarcation point 

 and Collinson point, Alaska. July, 1914, six males and three females (F. Johansen); 

 Barter island, Alaska, .June 24, 1914, female (D. .lenness). 



These specimens undoubtly represent the species described by Curtis. 

 The secondaries are yellowish with black holder. 



Under the generic name Dasychira, this species is referred to in several 

 arctic reports. Its life-history is only partially known, so the following obser- 

 vations are worthy of record.
