LYa5:NID^. 



One example 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 Zephjrus; the discoidal bar on each Aving is subject to 

 modification in the direction of complete effacement. 



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 when 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, Stgr,, has not so far been met with in 

 the region here dealt with. 



Zephyrus pedius, sp. nov. (Plate XXVII. fig. 3, 2 .) 



Female. Similar to the type of the same sex of Z. orientalis, Murray, but much darker in colour ; 

 the pale patch on primaries is of tlic same shape and placed in the same position, but it is 

 yellowish in colour ; there are no indications of a bluish marginal Hue 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. orientalis. 



Expanse 41 millim. 



One cxam])l(! taken by a native collector at Wa-ssu-kow, in July, at an 

 elevation of oUOO feet. The male, when discovered, will probably prove to 

 be green.

 of iirimaricH. Female dark grey, deep black at apex and on outer margin of primaries.
