" Expands 0'75 to 1 inch. Fringes of all the wings white. AVings dark brown in both sexes. The 

 male slightly tinged with light blue at the bases. Underside pale grey. Fore wings with a 

 straight central row of black spots, and an elongated discoidal spot. Hind Avings tinged 

 with blue at the base, with an irregular central row and two basal spots ; all the spots are

" 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 Antliyllis vuhieraria, Co-ronilla 

 varia, Astragalus, &c., in June and August." (Lang, I. c.) 



All the early stages of Z. minima {L. alsus) are described at some length 

 in Buckler's ' Larvse 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 Avith 

 L. sehriis ; the black spots are more or less absent. 



Grum-Grshimailo obtained this species in Am do, 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 with larger and more distinct black spots. It has also 

 been recorded by Bremer from the Bureja Mountains. 



Distribution. Europe, Northern and Western Asia, Altai, Amurland, and 

 Western China.
