44 L. de Niceville — Buttcrfiiesfroni the Indo-Malayan region. [No. 1, 



separated from the outer margin by a narrow band of the gi"ound- 

 colour, the white area commences narrowly at the second subcostal 

 uervule, increases in width to the abdominal margin ; a nai-row black 

 auteciliary thread from the anal angle to the third median nervule. 

 Underside, both ivings with the markings similar to those in the male, 

 but of a pure ochreous shade margined with fuscous. Forewing with 

 the apex also pure ochreous. The tail twice as long and twice as broad 

 as in the male. 



My single Javan male specimen here figured has the blue coloration 

 of the upperside of the forewing more extensive, the mai-kings of the 

 underside smaller,* the double marginal macular bands obsolete in the 

 hindwing, the brownish-ochreous apical area of the forewing more re- 

 stricted than in my numerous specimens from the Malay Peninsula and 

 the Battak Mountains of Sumatra, but as all these features seem to 

 be somewhat variable in my series of specimens, I think the S- amata 

 of Distant should fall before S. malika of Horsfield. 



The figure of the male is taken from my Javan specimen, that of 

 the female from a Penang example. I have also figured, Plate V, Fig. 

 17, the unique type male specimen of Siuthusa aspra^ Doherty (Journ. 

 A. S. B., vol. Ix, pt. 2, p. 180 (1891), from Mount Ai-juno, 5,000 feet.

 median interspace. Hindwing with the extreme base, the costa, and 

 the outer margin black, the rest of the wing white, but the area between 

 the abdominal margin and the second median nervule tinted with prim- 

 rose-yellow. Underside, forewing as on the upperside, but the grey 

 patches on the disc smaller. Hindwing with the base broadly black, 

 bearing a broad crimson patch, the disc of the wing rich chrome-yellow
