underside." The only Siamese specimen I have seen (a 

 female in Godfrey's collection) has but one small violet 

 dot in the apex of the cell of the hind wing and on the 

 underside only. A Singapore male is the same in this 

 respect, while another has this violet dot on the upperside 

 but not on the underside. The sub-apical spots of the 

 fore wing are rather smaller in drucei than in phoebus. 



Subgenus Salpinx, Hiibn. 



This subgenus is characterized by a patch of light 

 androconial scales on the upperside of the hind wing just 

 below the costa and entering the cell. The different species 

 occurring in the Malay Peninsula may be distinguished 

 thus : — 



a. No white in basal region of hind wing. 

 b. Well-defined light blue spot below lirst 

 median nervule of fore wing ; hind 

 wing without double row of marginal 

 spots leucogonys. 



b\ No light blue spot, (or if present, barely 

 visible) below iirst median nervule of 

 fore wing ; hind wing with double row 

 of whitish marginal spots, 

 c. Fore wing with well-deflned white 



apical spots singapura. 



c\ Fore wing without or with faint 



white apical spots deieani. 



c*. Fore wing with well-defined apical 



spots and marginal spots at apex crassa. 

 a\ Basal region of hind wing prominently 



white diocletianus,

As with so many Danaines, the females appear to be 

 rare. In the F.M.S. Museums series of 63 only 5 are 

 females. In the Raffles Museum there are 31 males to 7
