little below timber line. That from Banff was at about the same altitude 

 on Sulphur Mt., on Aug. i2tli. During 1904 Mrs. Nicholl met with males 

 only at Simpson River, about twenty miles north of INlt. Assiniboine, on 

 Aug. 13th and r4th, well above tree level. I have one of these specimens, 

 which she refers to var. Be/irii, and is very like Holland's figure of that 

 form. My Laggan specimen is similar, that from Banff I sent away. She 

 also sent me a few of a very similar form labelled ''Wilcox Pass, July 27th, 

 1907." The type of var. nanus, Neum., is stated in Mr. Wright's book to 

 have been taken near Calgary. 



80. Papilio niira, Edw. — Dr. Skinner says that a specimen I sent 

 him is "quite unlike Holland's figure of the type," and is probably Bairdii 

 or some slight var. of it, and that he has many like it from Colorado. 

 In Holland's figure the yellow is a trifle darker in shade, and the black 

 bar at end of cell on secondaries lighter, otherwise some of my short series 

 scarcely differ. HoU.ind's figures q{ ultra and Bairdii appear to differ, 

 chiefly in the intensity and extent of the black basal shading, and form of 

 anal eye spot. The Calgary species varies somewhat in these respects, 

 approaching both. 1 have a crippled Bairdii $ bred by Mr. Edwards 

 from Colorado eggs, and I must admit that its differences from Calgary 

 specimens have never been clear to me. Asierias (from Ontario) also 

 resembles the local form closely above in the male, but differs considerably 

 beneath. I have not taken and but rarely seen a specimen for several 

 years. 



84. Pamphila comma, Linn., var. Manitoba, Scud. — I took a male, 

 not quite fresh, near the summit of Mt. Piran, at about 8,500 feet, on July 

 20th, 1904. I am not sure to which name it is exactly referable. 



87. P. peckius, Kirby. — Fairly common some years. Pine Creek, 

 Billings's Mill, Gleichen, and Red Deer River. July. 



89. P. cernes, Bd.-Lec. — Head of Pine Creek, June 25th to 28th. 



90. Pyrgtis tesseiiata, Scud., var. occidentalism Skinner. The ordinary 

 north-western prairie form has been described as occidentalis by Dr. 

 Skinner in Ent. News, XVH, page 6, March, 1906, and figured on PI. 

 Xni, in the October number of that year, together with tesseiiata and 

 syrichtus. On page 278 Dr. Skinner states that it \z '*' not a species, but 



only a form or geographical race of tesseiiata It is smaller 



and whiter in colour, and the spots are larger in proportion to the ground 

 colour." He has specimens from N.-W. T. (Geddes), California, xVrizona, 

 and Texas. One of my specimens bears his label. Though far from 

 common here in the hills, it is usually very common all over the prairies
