I obtained specimens at Ningpo in April and at Hako- 

 date in August, and I have received examples, taken in 

 June and July, from Chang-yang, Moupin, Omei-shan, 

 and VVa-shan. 



The following forms of these species seem to be worthy 

 of varietal names. 



Var. perspiciui, nov. The rhombus, which is clearly outlined in 

 white, has its outer angle rather more produced than in the type, 

 and is well separated from the apical streak ; the lower angle extends 

 to the inner margin as in var. verunica. 



Occurs at Moupin, Omei-shan, Ichang, and Ship-y-shan. 



Var. obscwa, nov. Almost entirely fuliginous, the only markings 

 in evidence being the costal end of the white outline of the rhombus, 

 a wliite apical cloud, and some white dots representing the submar- 

 ginal line. 



Occurs at Moupin and Omei-shan. 



Distribution. SiKHiM ; KhAsis ; Borneo {Hamijson) ; 

 Central, Eastern, and Western China ; Yesso.
