328 Mr. H. J. Elwes on the 



lycormas from Yesso in Japan. The latter is variable in 

 the breadth of the border, and I agree with Leech in 

 considering it identical with scylla. 



68. L. seviiargus, Rott. 



A few specimens from the Bashkaus and Bija Valleys 

 at the end of July. 



69. L. argali, n. sp. 



I first saw this species on June 21st, flying below rocky 

 slopes at Kuyuktana, between the Kurai and Tchuja 

 Steppes, where the spring was only just commencing, and 

 some of the males were already worn. I afterwards found 

 it commoner at about 6000 feet in the beginning of 

 July in the mountains south of Kuch Agatch. The only 

 European species with which I can compare it is melanops, 

 but the colour of the upperside, which is a pale silvery 

 grey, is quite distinct, and its nearest allies appear to be 

 lygdamas, Dbldy., and conjierii, Grote, which are probably 

 identical, and are found in South Labrador, Anticosti Island, 

 Wisconsin, and as far north as the Great Slave Lake. There 

 is nothing like it in the Grand Duke Nicolas' collection 

 or in that of Grum-Grshimailo, and neither Alpheraky nor 

 Staudinger have seen anything like it. This species has 

 a remarkable tendency to grease, which I have observed 

 in no other Lycxna but sonoriensis, Feld. = regia, Bdv. from 

 South California, and which may arise from some peculiar 

 food plant of the larva. 



cJ Upperside pale metallic silvery blue, both wings with a black 

 marginal band, which is about as broad as tliat of melanops; under- 

 side grey, both wings with a white anteciliary line, succeeded by a 

 dark one, a white-edged black line at the end of cell in both wings, 

 aTid a dark marginal band, broken into spots, base of the hind-wing 

 dusky with scattered grey scales. Fore-wing below with a curved 

 series of five subequal roundish white-edged black spots placed one 

 in each of cells 2-6, and gradually receding from tiie margin as they 

 approach tlie costa. Hind-wing below with a nearly regular post- 

 median series of small subequal roundi^^h white-edged black spots 

 placed one in each of cells 2-7, and running parallel to the margin 

 and a similar spot near the basal third of cell 7 ; the latter and the 

 spot proper to cell 6 are sometimes obsolete or wanting, and the 

 postmudian series is sometimes extended towards the dorsum by one 

 or more additional spols. Fringes white, the basal half brown.
