agree with the key characters of the present subspecies, but seems 

 better placed here than elsewhere.

 tus Lake, 4 miles north of Hope on Frasier River, Kaslo, Nanaimo

Dates of collection for males are distributed from late spring to 

 late summer, unusually early and late seasonal dates being: May 5 

 at Berkeley, Calif.; May 9 at Hopland, Calif.; May 26 at Fullerton, 

 Calif.; June 27 at Marshfield, Greg.; August 8 at Warrenton, Greg.; 

 August 20 at Bixby Creek, Monterey Co., Calif.; August 22 to 26 at 

 Bothell, Wash.; and August 26 at Morley, Colo. Dates of collection 

 for females are from early spring to early fall, unusually early and 

 late seasonal dates being as follows: February 28 in Mill Valley, 

 Calif.; March 30 at Berkeley, Calif.; April 12 to 14 at Cazadero, 

 Calif.; April 24 at Robson, B. C; September 8 at Rj^an Creek, Men- 

 docino Co., Calif.; Gctober 3 at Salmon Arm, B. C; November 25 at 

 Glendale, Calif. The majority of collecting records for both sexes 

 are in the summer months. Since females appear much earlier in the 

 season than males and linger later, it is probable that overwintering 

 is as adult females.

 ferana, Whitman National Forest near North Powder, Greg., Aug. 7, 

 1952, W. K. Coulter. 9, from Choristoneura rosaceana 1911. 9,
