42 i Canadian Arctic Expedition, . 1918-18 



Genus Psychophora Kirby. 



Psychophora sabini Kirby. 



Psychophora sabini Kirby.: Supp. App. Parry's Voy. Disc. N.W. Passage, 

 1824. 



Two specimens from Bernard harbour, Northwest Territories, July, 1916 

 (F. Johansen). These specimens agree fairly well with Curtis' figure in the 

 Appendix to Ross' Second Voyage. 



Two other specimens, one from Wollaston Land, Victoria island, Northwest 

 Territories, summer, 1915 (D. Jenness) ; the other from cape Pullen, Wollaston 

 Land, Victoria island, August 18, 1915 (D. Jenness), may also be this species 

 but the specimens are not in very good condition. 



Genus Cidaria Treit. 



Cidaria species. 



Two Yukon specimens are in the Canadian National collection, both 

 collected by the late D. D. Cairnes, one on July 24, 1912, on the Nation river, 

 lat. 65° 30', long. 141°, the other on July* 23, 1913, in the White river 

 district, long. 141°. Both specimens were submitted to Mr. L. W. Swett, 

 who determined them as Cidaria frigidaria Gn.? He reported that the specimens 

 seemed to be very close to specimens from Lapland determined by Staudinger. 

 Unfortunately, both specimens are in poor condition. 



Genus Dasyuris Gn. 

 Dasyuris polata Dup. 



Dasyuris polata Dup.: Hist. Nat. Lep. Fr., VIII, (V), 402, 1830. 



Two specimens, on the authority of Mr. L. W. Swett, are at present placed 

 in the Canadian National collection under the above name. Both were studied 

 by Mr. Swett and compared with specimens in the Packard collection. One, 

 a male, was reported to match some of the rubbed specimens in this latter 

 collection. The second specimen, a female, is much larger but was thought 

 by Mr. Swett to be a female of polata. Referring to this latter specimen he 

 stated 1 " I think the character of the basal band being accentuated outwardly 

 rather indicates this species or a race of it". Both specimens were collected at 

 Tindir creek, Yukon Territory, international boundary, July 25, 1912 (D. D. 

 Cairnes). 



Genus Oporinia Hbn. 



Oporinia species. 



In the Canadian National collection there is one specimen belonging to 

 this genus which was collected in the Yukon by Mr. Jos. Keele, the label on the 

 specimen reading " Ladue river, August 21, 1905." This specimen was sub- 

 mitted by Mr. L. W. Swett, who named it Oporinia autumnata ? In reporting 

 upon it Mr. Swett remarked: " The markings are so effaced I cannot tell what 

 race or species it may be. The double lines on the hind wings are nearer together 

 than in typical autumnata, and it is not my race henshawi."
