178 THE CANADIAN ENTOMOLOGIST. 



less common. April 27th sees me "at it again." The temperature is 

 44° and the air is still. To-night there is a decided falling off in the 

 numbers of C. cineritia and L. fiapcea, and an increase in T. pacifica. 

 I take also Calocampa nupera (i), Mamestra (undescribed) (i), and one 

 each of two species entirely new to me ; one of them apparently a 

 Taeniocampa, — can it be an extreme form of pacifica ? — and the other 

 I should say allied to Xylma; but, alas ! my conjectures as to the generic 

 position of species often prove to be very wild mdeed, so little have I 

 studied classification. On the 28th I pay a visit to Mr. Hudson. He 

 searches his blossoms, and nets moths flying around them, and his take 

 has been even better than mine. In addition to most of the species I 

 have mentioned, he has come across a species of CucuUia new to me, taken 

 with the net only, and at least one fresh T^eniocampa. Some of my 

 species, too, have been more common with him, such as Scopelosoma devia 

 (in splendid condition), Tachnobia salicaruin, and the supposed Xylina ; 

 also Scopeloso7iia tristigtnata (2). However, he has not come across the 

 above-mentioned Mamestra, n. sp., nor one or two of the others which 

 fell to my lot. On 27th he took Plusia calif ornica and Erebia discoidalis, 

 perhaps a record date for the latter species, and a week earlier than I 

 observed it last year. On April 30th I saw E. discoidalis (i) and 

 Argynnis freya (i), and a species of Pieris, near the forks of Fish Creek, 

 about twenty miles west of here. I have certainly a record for Chionobas 

 alberta, Elwes., which I saw this year on May 3rd. Work at sallows this 

 week is not very prolific, and in fact T. pacifica is nearly over. Treacle 

 on May 3rd produced C. cineritia (common), and Mamestra, n. sp, (5), 

 nothing more. On the 5th I again visit Mr. Hudson. A cold breeze is 

 blowing from north-west, but on my way I, find C/iio?iobas alberta fairly 

 common on a hillside. This species, a full description of the life-history 

 of which will probably appear in No. XVI. of Mr. Edwards's " Butterflies 

 of North America," appears to have a marked preference for dry, stony 

 hillsides, where the grass is stunted in growth; just such localities, in fact, 

 where abounds that large anemone so common in this district. But this 

 morning the wind, and a large, slow-travelling cloud, which presently 

 obscures the sun, prevent my taking more than a dozen specimens. In 

 the afternoon Mr. Hudson and myself have fair sport amongst Argynnis 

 freya in a deep coolie, sheltered from the wind. Here we find a sprink- 

 ling of E. discoidalis, but only one C. alberta, which prefers, despite the 

 wind, to keep on higher ground. One specimen of a species of Eupithtecia, 

 several of a small yellow " Carpet," and one of a probable species of 

 Boarmia, complete the list up to date.
