THE CANADIAN ENTOMOLOGIST. 25 



199. P. astricta^ Morr. — Always common. End June to August. 

 Treacle and light. Exceptionally common during 1903, but in fewer 

 numbers than occulta. 



200. P. nigra, Smith. — Not common. July and August. Treacle. 

 I took a good series during 1903, when, though by no means common, it 

 turned up in greater numbers than previously. The species has a bluish- 

 black appearance, with sometimes a few paler shadings of ochreous or 

 brownish ochreous, but very different from the brown of astricta or the 

 gray of occulta It is hard to get in good condition. I had this standing 

 for some years doubtfully as X. casta?iea, a species with which I am not 

 acquainted. 



201. P. margaritosa, Harr., var. saucia, Hbn. — Not common. I 

 have no May or July records, but have taken it in fair condition from 

 middle to end of June, and perfectly fresh specimens from Aug. 9th to 

 Oct. 20th. I do not know the type from the variety, and may have both. 



202. Noctua Smit/iii, Snellen. — Common. July and August. The 

 erroneous reference to baj'a, Fabr., under which name this common North 

 American species used to be known, is not given in Dr. Dyar's list. 



203. N. Normaniana, Grt. — Not rare. July and August. 



204. N. jicncta, Grt. — Redescribed from Calgary by Prof Smith as 



fiate/acta, the type of which is in the U. S. Nat. Museum (Ent. News, VI., 

 333, and pi., Dec, 1895). Rather rare. End July to early August. 

 Treacle and light. 



205. N. substrigata, Smith. Described from Calgary, and figured 

 with the description. Common at light and treacle. Middle June to 

 August. Type in the U. S. National collection at Washington. 



206. N. Treatii, Grt. — In Can. Ent., XXXt., 200, it is stated that 

 this species is " not uncommon at Calgary." This is a mistake. It has 

 always been a decided rarity, and hard to get in perfect condition, until 

 1903, when it was decidedly common, and one of the most frequent and 

 regular visitors to light for some weeks. Mr. Hudson and myself took a 

 large number of most perfect specimens. Also taken at treacle. July 

 and August. 



207. iV! c-nigrum, Linn. — I used to look upon this as a rarity here, 

 but it has been more common during the past few seasons, though by no 

 means abundant. Treacle. Less frequently at light. July and August. 



208. JV. cynica, Smith, var. perumbrosa, Dyar ? — (Can. Ent., 

 XXXVI., 31, Feb., 1904, and 102, April, id.). A V dated Aug. 12th, 1903, 



January, 1905.
