" Expands 0-75 to 1 inch. Fringes of all the wings white. Wings dark brown in both sexes. The 
male slightly tinged with light blue at the bases. Underside palo grey. Fore wings with a 
straight central row of black spots, and an elongated discoidal spot. Hind wings tinged 
with blue at the base, with an irregular central row and two basal spots ; all the spots are 
surrounded by light rings. 
" Larva. Green, with an orange dorsal stripe edged with pale yellow, a lateral yellowish line and 
an oblique streak. It feeds on several kinds of vetches, as AnthyUis vidneraria, Coronilla 
varia, Astragalus, &c., in June and August." {Lang, 1. c.) 
All the early stages of Z. minima [L. alsus) are described at some length 
in Buckler's ' Larvae of British Butterflies.' 
My collectors obtained this species at How-kow and Ta-chien-lu at an 
elevation of about 10,000 feet. Chinese specimens are rather larger than 
European examples. The male is uniformly dark bluish grey and the female 
is rather more shining black. On the under surface the ground-colour is 
more bluish white than in European specimens, agreeing in this respect with 
L. sebrus ; the black spots are more or less absent. 
Grum-Grshimailo obtained this species in Amdo, Eastern Thibet ; Graeser 
states that he met with it somewhat plentifully at Pokrofka, in Amurland, 
and says the specimens were larger than those from Europe, and the under- 
sides lighter blue-grey Avith larger and more distinct black spots. It has also 
been recorded by Bremer from the Bureja Mountains. 
Distrilution. Europe, Northern and Western Asia, Altai, Amurland, and 
Western China.
