diversity of form in the various genera comprising this family, and they 

 have been divided into three sub-families, viz. : 



(1). The Theclinae or Hair Streaks, whose wings on the upper 

 side are generally some shade of brown and which very often have 

 on the underside some narrow white zigzag lines, also very fre- 

 quently having the hind wings adorned with one or more slender 

 tails. 



(2). The Chrysophaninae or Coppers, so called as in nearly all 

 the species, shades of coppery-red predominate. 



(3). The Lycaeninae or Blues. This sub-family contains by 

 far the largest number of species and is characterized by the 

 gorgeous blue of the most varying shades on the upper side of the 

 wings, especially in the males. It is the species of this latter sub- 

 family that I propose to deal with in this paper. 

 The Lycaeninae of Boreal North America comprise ten different 

 genera, six of which are represented in British Columbia. Up to date 

 there have been described thirty-eight distinct species with thirty-five 

 geographical races and seasonal varieties, making a total of seventy- 

 three different forms listed as occurring in North America. In British 

 Columbia we have nine species and nine geographical races, making a 

 total of eighteen distinct forms, which is about one-fourth of the total 

 number of "Blues" found in North America. 



We have had two Check Lists of British Columbia Lepidoptera 

 published, one was compiled by Mr. E. M. Anderson and published by 

 the Provincial Museum in 1904, and the other one published by the 

 Provincial Department of Agriculture in 1906, and compiled by some of 

 the officers of this Society. I have never been able to find out just who 

 assisted in this latter compilation, which was certainly an improvement 

 on the previous one, as many of the most glaring errors and misidenti- 

 fications were left out. I presume, however, that Mr. J. W. Cockle, of 

 Kaslo, was responsible for most of the "Micros," and no doubt the late 

 Rev. G. W. Taylor compiled the whole of the Geometridse, while the late 

 Capt. R. V. Harvey most likely listed the Diurnals. Looking back over 

 these lists, I find that in this sub-family, the Lycaeninae, there were 

 twenty-one forms listed in the 1904 Check List, of which one belonged 

 to the Chrysophaninae, and ten were misidentified ; of these, seven do not 

 occur in the Province, and in one case, one species was represented by 

 three different names, none of which were right. In the 1906 List, there 

 were fourteen forms recorded, of which eight were misidentifications, five 

 of them not occurring in the Province. 



I will now treat of them specificall}' in the sequence in which they 



are placed in Barnes and McDunnough's Check List, commencing with : 



No. 1. Everes amyntula Bdv. This is commonly called the 



Western Tailed Blue, as it has a verv minute tail at the anal ang^le of
