Eastern Pieridce. 373 



Vollenhoven (Mon. Pier. p. S5) describes as the female of tliis, 

 that which I consider a variety of paiiUna, and which Boisduval 

 described as neombo. It is true these resemble each other more 

 than the pairs I have placed together, but that proves little. 

 Horsfield paired them as I do, and the analogy of the sexes of 

 T. ega, from Australia, is in its favour. 



The Indian males and one from Sumatra (B. M.) are much 

 deeper yellow beneath, but the markings agree exactly. 



25. Tachyris amarella, n. sp. (PI. IX. fig. 2, ? .) 



Female. — Wings rounded, outer margin of uppers concave. 

 Above, sulphur-yellow ; costa and base of uppers dusky, a broad 

 black border occupying the outer half of both the wings, angu- 

 lated on the inner margins ; a row of five yellowish spots across 

 the uppers, the second and third largest. Beneath : the dark band 

 is violet-brown, paler near the margin, the spots violet-white, and 

 there are two more indistinct spots near the outer angle ; the base 

 of the upper wings is orange, and the disc of the lower whitish, 

 covered with light-brown scales. 



Expanse of wings 2^^ inches. 



jETab.—^ew Caledonia (one specimen, B. M,). 



Probably near T. alope.

'' Size and form of P. amasene, (Bd., iiec Cramer), which it com- 

 pletely resembles above. Beneath^ it is entirely different from all 

 the species of this group; the whole tmderside of the hind wings 

 and the tip of the fore wings are a clear yellow-ochre, with a row 

 of submarginal black spots." (Boisd.) 



Mab. — Woodlark Island (East of N. Guinea). 



Differs from T. alope as T. psyche does from T. paulina.

 Hab.—Java, Borneo, N. India {$ , ?, B. M., Coll. Wall.). 



My specimen from Borneo is rather larger than the type from 

 Java, and has a narrow black border only near the outer angle of the 

 lower wings. Boisduval's description of both sexes is good, but
