distributed over the high Rockies, but seldom plentiful." She reports 

 finding it rather common far north of Laggan last summer. Some of my 

 females have the centre row of black spots on primaries elongate as in the 

 \2cc. fasciata of hypopJiIceas. 



Nearly all my blues are with Mr. Fordyce Grinnell, who is making a 

 special study of the genus, and who, I hope, will soon straighten my species 

 out. Meanwhile I am able to make these few additions to my former 

 notes. 



[6oa. Lyccpiia lygda??ias, Doubl.. var, oro, Scudd. — I cannot look 

 upon the specimens I referred to under this head as being distinct from 

 what I have listed as Couperii^ which is very variable. Dr. Fletcher, in 

 commenting upon Mrs. Nicholl's record of Couperii from Calgary and the 

 Rockies, says : "The mountain form here referred to is called lygdamas 

 by Canadian collectors, following Mr. W. H. Edwards."] 



63. Z. shasta, Edw. — I have not since seen the species from 

 anywhere near Calgary, but have found it, somewhat sparingly, on either 

 side of the Red Deer, north-east of Gleichen. It there frequents dry 

 gravelly ground, preferably at the top of isolated knolls so common in the 

 deep, water-worn coulees in that alkaline country, or close to the edge of 

 banks, seeming to be fond of the flowers that grow in such situations. A 

 few specimens were found in the coulee bottoms, June 20th to July 9th, 

 though on the latter date most of my captures were much worn. I cannot 

 distinguish the form from specimens received from South Park, Colo. 

 The Red Deer locality is strictly prairie, and its occurrence there is rather 

 peculiar. 



65. L. acmo7i, Doub.-Hew. — I have taken it on the Red Deer, flying 

 wiih shasta^ but even less commonly. With Mr. Hudson I also took one 

 or two in a dry pit about a mile from Gleichen station, July 5th to 9th, all 

 in fine condition. Dr. Fletcher says : " It is the ordinary form of acmo7i 

 not uncommon on the plains." Specimens in my collection from Colorado 

 and California, which Dr. Fletcher tells me are the same species, have 

 large spots, and most of them a wide red band beneath. It is not unlikely 

 that the Banff specimen previously recorded may be battoides. 



68. Pieris sisymbri, Bd. — Until recently I confused this species with 

 a dark var. of occide?italis, and I find that my Pine Creek records were 

 erroneous. I have, however, a pair of sisy?nbrt from Laggan, received 

 some years ago from Mr. Bean, the female being greenish-yellow, and 

 dated "end of May." These, with a third specimen, female, from Glen- 

 wood Springs, Colo., form a basis for comparison. The Laggan male
