THE CANADIAN ENTOMOLOGIST. 161 



62. Z. rustica, Edw. Common everywhere. June and July. 



63. L. shasta, Edw. A single specimen on the Bow bottom, near the 



mouth of Fish Creek, on June 21st, 1894. The name is on the 

 authority of Mr. W. H. Edwards. Visits to the locality since 

 have failed to produce any more. 



64. Z. melissa, Edw. Common, end of May to August. A remarkably 



variable species. I have had the names Scudderii and A?ina from 

 Mr. Edwards, and have seen Banff specimens, labeled Scudderii 

 by Dr. Fletcher, which agree with specimens in my series. I 

 picked out some half dozen specimens showing the range of 

 variation as much as possible and sent them to Dr. Skinner, who 

 wrote : " They are all undoubtedly one species, and are a little 

 off typical melissa, and near to var. Aunetta." Mr. Gregson 

 lakes the same species at Lacombe. Judging from Mr. Edwards's 

 opinion about certain forms I sent him, it is not unreasonable to 

 suppose that the record of Anna, Edw., from Belly River, refers 

 to this species. 



65. Z. acmon, Doub.-Hew. Banff, Aug. 7th (Sanson). I have seen this 



species, and believe it to be distinct from anything else here 

 listed. 



66. Z. pseudargiolus, Bd.-Lec. I have a specimen taken by Mr. Elwes 



within a mile of my house, on May 24th, 1895, but neither 

 Mr. Hudson nor myself have ever taken it. Mr. Gregson records 

 vars. marginata, Edw., and facia, Kirby, from Lacombe (end of 

 May, not common), and Mr. Sanson says he takes var. facia at 

 Banff (May 25th). 



67. Z. amyntula, Bd. Common in June, especially near the spruce. 



Lacombe, in river bottoms, June, not common (Gregson). I have 

 seen Lacombe specimens which Mr. Gregson has under comyutas, 

 but cannot separate them from what I have as amyntula. 



68. Pier is sisymbri, Bd. Rather rare on Pine Creek. May and June. 



Also at Banff and Laggan. 



69. P. protodice, Bd.-Lec. June and August. Double brooded, the 



second brood being fairly common. The commonest form here 

 agrees with protodice, as described in French's "Butterflies of the 

 Eastern U. S. and Canada," but Dr. Fletcher gave me the 

 name occidentalis for this form, which is also like occidentals
