473. Plemyria ( Rheujuaptera) hastata^ Linn. — Common in the 

 spruce. June and early July. 



474. P. tristata, Linn. — Very common. End May and June. 



475. P. sociata, Bork. — Common. Middle June to middle July. 

 According to Mr. Charles Ci. Barrett this is the same as pAiropean 

 subtrisiata, Haw., not substriata, as Dyar writes it. 



476. P. iuctuata, Schiff. — Very common in the spruce some years, 

 but seems to be rare on Pine Creek. Middle June and July. 



477. P. Georgii, Hulst. — I always looked u])on this as a great 

 rarity until 1903, when it was fairly common. On flowers oi So/idago 

 virgaurea at night, and also came to treacle. End Aug. and Sept. 



478. P. sicbrosuffusata, Pack. — Not rare. May and June. The 

 colour of the secondaries is decidedly an orange-yellow, but I gather from 

 Mr. Taylor that Packard described them as "brick-red." He writes : "I 

 have had abundant material for study, and there is no doubt as to the 

 species. Our specimens and California ones are exactly the same, and 

 apparently our idea of orange-yellow was Packard's notion of 'brick-red.'" 

 Dr. Holland's figure looks like the Calgary species bleached. One of my 

 specimens bears a red-ink label " Ochyria canieata^' on Hulst's authority. 



479. ZeJiophleps lignicolorata, Pack. — Not rare. Middle July to 

 middle Aug. I have it from the flat prairie to the mountains at B:inff, 

 but did not see it there above 6,000 feet. 



480. Mesoleuca gratulata, Walk. — Rather common in the spruce. 

 My only dates are May 30th to June 6th, and my four specimens are per- 

 fect. Mr. Taylor says the species is distinctly western. 



481. Mesoleuca ccesiata, Schiff. — I have taken in good condition at 

 Laggan, from July i8th to Aug. loth, from 5,700 ft., and occasionally far 

 above the timber line, one capture being on the summit of Saddle Mt., 

 7,900 ft. I have a head of Pine Creek $ , taken at light on Sept. 3rd, 



1904, which Mr. Taylor refers as a var. of this species. It entirely lacks 

 the faint though obvious ochreous tinge present in the Laggan form, the 

 ground colour is paler, with distinct smoky central and terminal bands. The 

 specimen is somewhat worn, I took an exactly similar specimen during 



1905. In the Kootenai list Dr. Dyar says that he found this a high 

 altitude species, and records it from Banff, Alta , on Sept. loth. 



482. M. lacustrata, Guen. — Not common, ^[iddle June to middle 

 July. Notwithstanding the generic separation, this species seems raiher 

 easy to confuse with Plemyria sociata without some knowledge of the
