S5. Tackijris corinna, n. sp. 



Male. — Above, exactly like T. liberia. Beneath, the upper 

 wings have a black border along the outer margin, broadest at 

 the apex and regularly narrowing to the outer angle; just within 

 this at the apex is a spot yellower than the rest of the wing ; the 

 lower wings are uniform chrome-yellow, with a narrow black outer 

 border, whereas there is a mere edging in T. liberia, which has a 

 border of light yellow. 



Expanse of wings l|r inch. 



Female. — White, base of wings broadly dusky, shading into a 

 broad black border, which is broadest at the apex and reaches 

 t!ie anal angle. Beneath : the border is of the same w'idth and 

 purplish, the disk of the uppers is greenish-white, with the base 

 yellow, the lower wings are deep yellow. 



Expanse of wings 1^ inch. 



i/«6.— Waigiou (Coll. Wall.). 



While the male so closely resembles T. liberia that it seems to 

 have been considered the same species, the female differs alto-

Ifrtft.— Amboina (Coll. Wall.). 



This species, well figured by Cramer, appears to be restricted 

 to the small island of Amboina, since upon the adjacent island of
