white band commoa to both wings. Underside as in male, but with 

 the yellowish basal streak on the costal margin more prominent. 

 Cilia of both surfaces brown.

The male of tins species is well figured by Herr Snellen, and the 

 figure here given of the female is from a specimen in Dr. Staudinger's 

 collection. 



Mr. W. Doherty obtained a number of this insect in S. Celebes 

 in August and September. 



The white disks below are often more or less covered with light 

 sulphur-yellow.

So far as we know this is the only species of the group which 

 has a blue female. 



The type specimens are the only ones we have seen. 



E. Tlie CTANEA group. 



The insects I have placed in this group may be recognized by 

 the short Hnear tail to the lower median nervule of hind wings. 

 There are several easily distinguished forms.

Hah. Amboina (Doherty, Mm. D.) ; Ceram \ 



We possess a number of specimens from Amboina which do not 

 vary and which, agree well with Cramer's figures and whence his 

 type was probably obtamed. The locality he gives is " Indes Occi- 

 dentales." His figure shows two tails to the hind ^vings, which is 

 of course incorrect, but it is in other respects a good one. 



As has been already pointed out by Herr Semper (Mus. Godef. 

 xiv. p. 155), this form shows considerable differences from its 

 Australian representative which has been described under the name 

 Cupido arinia by M. C. Oberthiir : in the male by the black band 

 on the hind wing below being very much narrower and consequently 

 allowing a much greater extent of white, and in the female by the
