Lepidoptera 41 i 
Genus Lygris Hbn. 
Lygris destinata Moesch. 
Lygris destinata Moeschler: Wien. Ent. Monat., 375, IV, 1860. 
Among a small collection of lepidoptera made in the Yukon in 1908 by Mr. 
Geo. Stewart, the specimens being now in the National collection at Ottawa, 
are three specimens of Lygris destinata Hbn. taken at Nordenskiold, 63 miles 
from Whitehorse, Yukon Territory, August 23, 1908. With these specimens 
are two other examples taken on the same day and at the same place, which 
resemble destinata but the antemedian band and the subterminal area are 
distinctly yellowish, thus approaching, according to Dr. McDunnough, who 
examined the specimens, svmilis of Walker. 
Ten other specimens of what is probably this latter form were brought back 
by members of the Canadian Arctic Expedition. These were taken as follows: 
Nome, Alaska, August 24, 25, 1916, 4 specimens (F. Johansen); cape Pullen, 
WoUaston Land, Victoria island, Northwest Territories, August 18, 1915, 4 
specimens (D. Jenness); Bernard harbour. Northwest Territories, August 25, 
1915, 2 specimens (F. Johansen). 
Unfortunately most of these specimens are in poor condition. 
Genus Dysstrotna Hbn. 
Dysstroma truncata Hufn. 
Geometra truncata Hufn.: Berl. Mag., IV, 602, 1769. 
One specimen in the Canadian National collection from Bartlett bav 
off Glacier bay, Alaska, June 10, 1907 (D. H. Nelles). 
This specimen is in poor condition but Dr. J. McDunnough who examined 
it, considered it to be this species. In the Barnes' collection there are specimens 
of truncata from southern Alaska. 
Dysstroma citrata Linn. 
Phalcena citrata Linn.: Faun. Suec, p. 332, 1761. 
One specimen from Latouche, southern Alaska, September 3, 1916 (F. 
Johansen). 
The specimen is in poor condition but is apparently a form of this species. 
In addition there is in the Canadian National collection a specimen from 
the Yukon, namely, from Burwash creek, Kluane district, August 4, 1914 
(D. D. Cairnes), the determination of which was confirmed by Mr. Swett. 
Genus Xanthorhoe Hbn. 
Xanthorhoe abrasaria congregata Wlk. 
Thera congregata Wlk.: Cat. Brit. Mus., XXIV, 1,264, 1862. 
In the Canadian National collection are four specimens from the Yukon, 
namely from wagon road between Whitehorse and Dawson, Yukon Territory, 
July 7 to August 2, 1908 (Geo. Stewart). The species was not met with by 
Mr. Johansen or other members of the Arctic Expedition. 
In Dyar's Catalogue,^ congregata of Walker is given as a synonym of 
imangulata of Haworth. This has been corrected by Barnes and McDunnough 
in their Contributions^ and given in their recently issued check list^ as the 
American race of abrasaria.
