Under surface in both sexes quite clifTorenfc in colour and markings to the other species. It 

 is mother of jjcarl (silver), shining whitish grey, similar to that of sijla, Koll., from N. India. 

 The fore wings have beyond the middle a strong dark brownish-grey streak, and beyond this a 

 somewhat broad dark curved band from costa to first median ; before the outer margin is a 

 double series of dusky lunules." {Staudinfjer, I. c.) 



Male. Bluish green ; secondaries broadly bordered with black. Pringe whitish. 



Female. Brownish ; primaries rather paler on disc, and with some pale spots beyond the discoidal 

 cell. 



Under surface pale bluish white in the male, and whitish grey in the female ; the primaries have 

 the following dusky markings : a bar at the outer extremity of the discoidal cell, an oblique 

 dusky band bordered outwardly with white, and a submarginal scries of spots ; secondaries 

 have a discoidal bar and interrupted dark grey central band bordered with whitish ; there is 

 a double whitish wavy submarginal line and a line of the same colour parallel with outer 

 margin ; a black spot bordered with fulvous at anal angle, and above it there is another black 

 spot surrounded with fulvous in the first median interspace. 



Expanse, S 3G-38 millim., $ 31-38 millim. 



Graeser states that the larva feeds in June on Quercus mongolica. 



This insect, which is described by Staudinger from the coast region of 

 Amurland, also occurs in Yesso ; there was a large series in the late Henry 

 Fryer's collection from the latter locality. Dr. Fixseu records a female 

 specimen from Corea, taken in July. 



Zephyrus hecale, sp. nov. (Plate XXVII. figs. 1 $ , 2 .) 



Male. Of the same green colour as T. ta.vila, but much suffused with blackish in certain lights ; 

 the black marginal borders of the primaries are very broad, and those of the secondaries still 

 broader, the abdominal margin of these wings is also broadly blackish ; the primaries have an 

 elongate black discoidal spot. Under surface similar in colour and pattern to that of 

 Z. tarila, but the white markings are silvery and more slender; the primaries have a dark 

 discoidal spot bordered with silvery white, the central line of secondaries forms a more 

 distinct W before reaching abdominal margin, and the inner submarginal line on these wings 

 is not well defined ; the tails are rather longer. 



Female. Blackish ; the primaries have an orange spot at the outer extremity of discoidal cell, and 

 one between it and the outer margin intersected by the third median nervule. Under surface 

 as in the male, but the central lines are rather wider. 



Expanse, <S 42 milHm., 2 38 millim. 



The male of this species was taken at Wa-ssu-kow in July, at an elevation 

 of 5000 feet, whilst two females were captured at Ta-chien-lu in July, at 

 about 8000 feet. 



This species is also allied to Z. (T.) tsaiujJcie, Oberthiir, but the male has 

 no purplish blue at angle of secondaries, and the female is not marked -Avith 

 blue on upper surface ; the orange markings on primaries are more like those
