CELASTRINA ARGIOLUS. 423 



either with or without the confluent discal patch. Described from 16 specimens 

 (8 <? s and 8 ? s). Types of both sexes deposited in the U.S. National Museum 

 (Fletcher). 



The common spring form at Kaslo, on Koofcenay Lake, British 

 Columbia (teste Cockle). The peculiar feature seems to be that, 

 whilst the $ and the underside of both sexes are generally of the type 

 associated with the spring forms, the upperside of the J has the wide 

 costal and outer marginal border of the forewings, and, in addition, 

 specially suffused hindwings, features usually associated, in our PalaB- 

 arctic forms, with the summer brood. The description appears, as 

 already noted, to agree very closely with that of echo, Edw.

 azure-blue, paler in the disk and silvery on costal margin, secondaries greyish- 

 blue, with a broad azure margin ; a black line edges the hind-margin of both 

 wings, expanding towards apex of primaries into a border, and running a little 

 way along the costal margin; fringe of primaries white, cut with black by the 

 nervures ; of secondaries, sometimes barred with black, but usually wholly white. 

 Underside pure white, or white with a bluish tinge ; primaries with a dark discal 

 streak and a transverse series of six black streaks set obliquely ; secondaries have a 

 discal streak, three points near base, and eight points or streaks crossing the disk 

 in a tortuous line ; both wings bordered by confluent spots, forming a crenated 

 band, each spot enclosing a darker point. Female : Upperside of both wings of a 

 deeper and more metallic blue ; the primaries have a broad fuscous hind-margin ; 

 in some cases this colour extends along the costal margin to the base, where it is 

 sprinkled with blue ; a faint discal streak; hind-margin of secondaries bordered by 

 a row of small fuscous spots. Underside dark grey, sprinkled with blue at the 

 base of both wings ; the fuscous spots disposed as in the 3 , but larger and coarser. 

 [Variety a. Upperside wholly fuscous. f] Massachusetts, New York, Wisconsin, 

 Lake Winnipeg. There are three specks of Lycaenae in North America that 

 much resemble each other, viz., lucia, of Kirby; pseudargiolus, of Boisduval ; and 

 a third, hitherto confounded with the latter, which I describe as neglecta. Pseudar- 

 giolus resembles argiolus, of Europe, in form, size, and colour above, and was 

 considered by Abbott and Smith as identical with it. Both wings are wholly 

 violet-blue, with a pinkish tinge ; the underside is greyish-white, and the 

 hind margins are bordered by a broad serrated band, the teeth of which are 

 separated almost to their bases. This band appears as if stamped on the 

 wing. The colour of neglecta is azure-blue on primaries, of secondaries grey- 

 blue, with an azure margin ; the underside is pure white or bluish-white, and the 

 marginal band is confluent and serrated. Lucia is uniform light silvery- blue 

 above and cinereous below, with a border as in neglecta.* The number, shape and 

 arrangement of the spots on the underside of these species are similar, mostly 

 differing in degree of fineness ; in pseudargiolus they are very delicate ; in neglecta 

 much less so ; in lucia heavy and coarse. Pseudargiolus varies much in size ; it 

 appears to be rather a southern species ; and is common on the mountains of 

 Western Virginia, and is occasionally met with in New York. Neglecta is common 

 in New York, and I have received it from Wisconsin and from Lake Winnipeg. 

 Lucia seems to be confined to the northern parts of the continent (Edwards). 



Edwards' neglecta has been generally considered to be the usual 



f Afterwards proved to be 3 (see anted, p. 419).
