Lepidoptera 5 1 
One of the specimens taken between latitudes 67° 25' and 66° 30', long. 
141° is shown on Plate III, fig. 3, together with the underside of a specimen 
from Nansen creek, Yukon Territory (fig. 4). Barnes and McDunnough in 
their "Contributions," vol. Ill, No. 2, Plate VI, figure a male and a female of 
arctica from Chatanika, Alaska. 
Pieris napi pseudobryoniae Verity. 
Pieris napi pseudohryonice Verity: Rhopalocera Palsearctica, 146, 1908. 
Specimens of this form in the Ottawa collection are from the following 
localities: Bartlett bay, off Glacier bay, Alaska, June 10, 1907, 2 males, 1 female 
(D. H. Nelles); Alaska, 1894, 2 females (Ogilvie). A male and a female from 
Bartlett bay are shown on Plate III, figs. 1 and 2. 
In the Ottawa collection there is a specimen of napi taken at Dease lake, 
northern British Columbia, June 17, 1887 (G. M. Dawson). Fletcher^ recorded 
this as venosa Scudd. This latter form was described from California. I have 
recently compared the specimen from Dease lake with Edwards' figure of 
oleracea-hiemalis on Plate 2, Vol. 1, Papilio, and while the veins are more heavily 
lined, it otherwise is similar to the figure referred to. It is certainly different 
from specimens of venosa from California in the Canadian National collection. 
Long series of such northern forms are required before one can arrive at any 
satisfactory decision regarding their status. 
Genus Euchloe Hbn. 
Euchloe creusa Dbldy. 
Antliocharis creusa Dbldy.: Gen. Diur. Lep., pi. 7, 1847. 
Three specimens from northern localities are in the Canadian National 
collection, namely from Pelly river, Yukon Territory (W. Ogilvie), and between 
latitudes 67° 25' and 66° 30', June 12-15, 1912 (D. D. Cairnes). 
The specimen from Pelly river was named A. hyantis some years ago by 
the late Dr. Fletcher. This latter name, however, according to Barnes and 
McDunnough-, should evidently be used for the Californian race of creusa. 
In 1908, Mr. C. H. Young, of the Canadian Geological Survey, found the 
larva? abundantly at Departure bay, British Columbia, feeding on tower mustard, 
Arahis glabra (L.) Bernh. Unfortunately he did not make any larval notes, 
but brought to me on his return to Ottawa a number of the chrysalids, from one 
of which a butterfly had emerged and from another a tachinid parasite of the 
genus Exorista^. The chrysalid is shown on Plate III, fig. 7. 
Euchloe ausonides Bdv. 
Anthocharis ausonides Bdv.: Ann. Soc. Ent. Fr. (2), X, 286, 1852. 
Four northern specimens of this species are in the Canadian National 
collection taken at the following localities: Telegraph creek, Stikine river, 
northern British Columbia, May 27, 29, 1887 (G. M. Dawson); Cassiar trail, 
10 miles west of Dease lake, British Columbia, June 4, 1887 (G. M. Dawson); 
Pelly river, below Hoole river, Yukon Territory, July 5, 1907 (J. Keele).

^ The specimen which was much damaged was submitted to Mr. John D. Tothill, who reported 
that it belonged to the genus Exorista and that it may be E. vulgaris Fall.
