have been proved to be two distinct species, typical shasta occurring 

 throughout the Sierra Nevada range as far north as Oregon. Lupini 

 does not have a wide range in this Province, the only known localities 

 being Kaslo and the Okanagan district. 



No. 12. Philotes battoides Behr. or Behr's Blue. This, like the 

 preceding, is not at all a common species with us, and is taken in the 

 same general localities as lupini. Apart from generic structure, they are 

 very much alike superficially, but may be distinguished by the following 

 diliferential characters ; in lupini the males have an orange band on the 

 outer margin of the hind wings on the upper side, while in battoides the 

 orange only shows through at the anal angle. Underneath in battoides 

 the ground colour is of a darker gray with the spots, especially on the 

 primaries, being more or less quadrate. The easiest recognized point 

 of diiTerence, however, lies in the presence of a marginal row of metallic 

 bluish green scales on the under side of the hind wings of lupini which 

 is absent in battoides. 



No. 13. Phasdrctes piasus Bdv. or the Arrowhead Blue. This is 

 better known under the name of sagittigera Feld., which name is now 

 placed in the synonymy. It was so named in reference to the white 

 sagittate or spear-head marks which show so prominently on the under 

 side of the secondaries. Our records show at present only a limited 

 distribution, the specific localities being Armstrong, Vernon, Penticton 

 and Osoyoos. 



No. 14. Glaucopsyche lygdamus race ore Scud. This and the 

 following race have been going under various names in collections in 

 this Province for a number of years, such as antiacis, antiacis var. behri, 

 lygdamus, and couperi. Moreover, these names have been applied indis- 

 criminately to each of these two forms. The race oro, of which 1 have 

 a long series from Lillooet, Okanagan Landing, Armstrong, Penticton 

 and Kaslo, is differentiated from Columbia by the much paler blue on the 

 upper side of the male. The females show a greater degree of differ- 

 entiation, ore being of a uniform smoky brown with a few blue scales 

 basally, while Columbia is almost black, heavily shot with blue, giving it 

 the appearance of being bright blue with a wide black border. The two 

 races differ in the ground colour of the under side, oro being of a 

 brownish-drab colour, while the majority of the specimens of Columbia 

 are of a light stone colovir. 



No. 15. Glaucopsyche lygdamus race Columbia Skin. This form 

 was described by Dr. H. Skinner in the Ent. News, May, 1917. The 

 type and paratypes are from Port Columbia, Wash. Amongst other 

 localities mentioned are Corfield, Vancouver, which, I imagine, is meant 

 for Corfield near Duncan, on Vancouver Island. This race of lygdamus 

 occurs and is fairly common on Vancouver Island about May, and is 

 also taken in the Lower Fraser Valley, which in the main has a similar 

 fauna to Vancouver Island.
