2 • Upperside as in T. danis, but the black borders narrower 

 and more evenly defined. Underside as in c^ . 



Head, thorax, abdomen, and legs as in T. danis. 



Expanse, S lyo— 2 inches, $ 2 inches. 



Hab. Ceram. 



This form occurs only in Ceram and does not appear to vary. 

 The types are in Messrs. Godman and Salvin's collection, and 

 specimens are also contained in the British Museum. 



The cilia of both sexes are alternately black and white, but not so 

 markedly as in T. danis (typical).

Hab. N. Queensland ' ; C. York ^. 



We have not seen this species, the male of which is described as 

 light greyish blue above, with the fringes of both wings alternately 

 black and white below. 



Mr. Miskin notes : " This is near to sebcn and the markings are 

 similar to that species, but the decidedly different tint of blue, the 

 absence of metallic sheen, and the somewhat larger size seem to 

 distinguish it." He says of the female, " As in male, except that 

 the blue is much less pronounced, the upperside being almost black." 



It is notable as being the only species which has non-metallic 

 blue.

S . Allied to T. danis, c? . Generally larger. Upperside 

 somewhat lighter blue with less sheen ; the white disk of fore

 border gradually widening towards the anal angle. Hind wing — 

 outer half black, covered with greyish-blue scales, thickest towards 

 the apex. Underside as in T. danis, but the black borders 

 considerably wider, more especially in the hind wing, in whicb the 

 white band becomes straighter, much narrower, and is placed 

 before the middle. Cilia alternately black and white on both 

 surfaces.
