orange patches near the anal and outer angles. Size the same as 

 T. a da. 



Hab.—Wc Island (Coll. Wall.). 



The female of this form differs so strikingly in appearance 

 from that of T. ada, which is nearly constant through a wide 

 range of localities, that I am induced to separate it, although, like 

 the various forms allied to T. hippo, the differences are not such 

 as are usually considered to be specific. 



14. Taclujris ahnormis, n. sp. (PI. VIIT. fig. 5, $.) 



Female. — Fore wings with the outer margin more rounded than 

 in the female of T. ada. Above, pearly white, the body and 

 adjacent parts of the wings with a faint greenish tinge ; upper 

 wings with the costal margin dusky, and a large subtriangular 

 apical patch extending from the middle of the costa to the outer 

 angle blackish-brown ; lower wings with a border of the same 

 colour, widest at the outer angle and not reaching to the anal 

 angle. Beneath, upper wings as above, with the base ochre- 

 yellow, and a small elongate patch of cinnabar-red, situate half 

 way down the cell close to the subcostal nervure ; under wings 

 entirely brown-black, the base tinged with ochreous-yellow, which 

 extends a short distance along the costal and anal margins. 



Expanse of wings 2| inches. 



Hab.—^evi Guinea (N. W. extremity) (Coll. Wall.). 



This very remarkable species appears to come best here. In 

 colouration it bears a strikin^r jreneral resemblance to the beautiful 

 nymphalideous butterfly, Mynes Geoffroyi, which inhabits the same 

 country.

Hab.~ Java, $, $, B. M. (Horsfield). 



This species appears to be confined to the island of Java. 

 It is well described by Godart and Boisduval, and there can be 

 no doubt that Vollenhoven's sidphurea is the female, and the 

 locality, "Moluccas," which he gives from Reinwardt, an error. 

 It is represented in the other western islands and in Celebes, by 

 T. nalJudia, Feld., which also occurs in Java, most likely inhabiting 

 a separate district in that island.
