1893.] THE BUTTEKFLIES OF THE GENUS THTSONOTIS. 539 



A. The DANis group. 



In this group the males are more or less metallic blue, and both 

 sexes have a white band common to both wings. The species are 

 best distinguished by the presence or otherwise of the metallic 

 blue on tbe upperside of the females. In T. serapis this character 

 seems at its best, as the hind wing is suifused all over, and the 

 base of the fore wing very strongly, with metallic green scales. 

 T. danis and var. harpaia havje the metallic scales along the costal 

 margin only, whilst T. pldloslratus, T. apolloniu^, and T. regina 

 are absolutely without any metallic scales on the upperside. 



T. syrius and T. ribhd we have not seen, but from Mr. Miskin's 

 note concerning his species the female has apparently some blue on 

 the upperside. 



The females of all the species of this group have the outer 

 marginal band of the hind wings beneath broader, and the blue 

 more extensive, than the males.

This is perhaps the easiest species of the group to distinguish, 

 as it is the only one in which the hind wings of the female are 

 suffused with metallic scales. We have in our collection a number 

 of specimens collected by Mr. GervasMathew, E.N., in Queensland, 

 but the precise locality is not noted. They vary considerably in 

 size and also somewhat in the width of the metallic fascia on the 

 underside of the hind wings. The extent of blue and also of 

 white on the upperside of the male seems to be quite constant.

Hob. Amboina : Ceram ; Cardwell to C. Tork. 



Although Cramer gives " Indes Occidentales " as the locaUty of 

 this well-known species, there can be no doubt from an exam- 

 ination of his figure that he delineates an Amboinese example. 

 My authority for giving Ceram is a pair ( d" $ ) in Messrs.
