patcli and the smallest speck. The amount of green com- 

 posing the colour of primaries is also a variable quantity, 

 and in one of the Kulu examples it is almost absent, 

 leaving the insect of a blackish-grey colour. In the 

 majority of the specimens the whitish secondaries are 

 conspicuously bordered with fuscous, but in others they are 

 almost entirely suffused ; all the intergrades between the 

 two extremes occur,

 Specimens from Yokohama, Oiwake, and Gifu in 

 Piyer's collection ; I obtained examples at Gensan in July 

 and my native collector at Nikko. Gnoma, Butl,, is of 

 large size but does not otherwise differ from the

This species seems to have occurred, in June and July, 

 in most of the localities in Western China visited by my 

 collectors. 



Hampson includes both albidisca, Moore, and nivesccns, 

 Butl., in auroviridis, Moore, but with one exception, a 

 specimen from Chia-kou-ho, all my examples are referable 

 to albidisca. 



Distribntion. Dharmsala ; Bengal ; Naoas ; Nilgiris 

 {Hampson) ; Western China.
