378 LYC-ENID.E. 
One examisle of this form was taken by a native collector at Omei-shan in 
July at 5000 feet elevation. 
This species differs considerably in colour, shape, and size from the other 
green species of Zephyrus; the discoidal bar on each wing is subject to 
modification in the direction of complete effacemeut. 
The female exhibits very little variation on the upper surface either in 
colour or marking, but there is one specimen from Moupin with a broad 
blue stripe above inner margin and a blue suffusion in the discoidal cell, as 
in female Z. taxila, var. fasciata. 
Many male specimens of this and other species of Zephyrus in collections 
have a purplish suffusion. I have captured numerous examples of this 
species and Z. taxila, var. japonica, but never observed this suffusion in the 
specimens Avhen alive ; probably, therefore, the change in colour is due to 
some chemical action which takes place either in the killing, setting, or 
relaxing of the insects. Var. cognata, vStgr., has not so far been met with in 
the region here dealt with. 
Zephyrus pedius, sp. nov. (Plate XXVII. fig. 3, ? .) 
Female. Similar to the type of the same sex of Z. orientalls, Murra}-, but much darker in colour ; 
the pale patch on primaries is of the same shape and placed in the same position, but it is 
yellowish in colour ; there are no indications of a bluish marginal line on secondaries. The 
under surface is silky pale greyish white, which obscures all the whitish markings, leaving 
distinct only the dark lines, and even those on the secondaries are only faintly indicated ; the 
orange markings on outer margin of secondaries are the same as in the type, but that at 
anal angle is not continued above any part of the abdominal margin as it is in Z. orientalls. 
Expanse 41 millim. 
One example taken by a native collector at Wa-ssu-kow, in July, at an 
elevation of 5000 feet. The male, when discovered, will probably prove to 
be green. 
Zephyrus saphirina. 
Thecla saphlriua, Staudiiigcr, Rom. sur Lep. iii. p. 135, pi. xvi. figs. 3, 4, 5 (1887) ; 
Pryer, Rhop. Nihon. p. 14, pi. iv. figs. 9 a, 9 6 (1888). 
Smaller than the other green TJiecla; and with shorter tails. Male dark blue-green, less shining 
than other species. Primaries have only a black marginal line, the secondaries have a narrow 
black border. Fringes in both sexes white on lower half of secondaries and at inner angle 
of primaries. Female dark grey, deep black at apex and on outer margin of primaiies.
