" Allied to T. stigmata. Differs above in the absence of the short black 

 oblique bar or brand on the forewing ; the maculated band being slightly 

 more prominent. Underside similarly speckled, the bands on hindwing 

 not lunular, but composed of a slightly broader series of spots ; some spots 

 also present round the cell spot. 



Expanse : |J inches. 



Habitat : Cherra Punji, Assam." (Moore, I. c.) 



Also recorded from Cachar (Wood-Mason and de Niceville). 



Mr. de Niceville is inclined to believe this species synonymous with 

 the preceding, but as it apparently possesses a discal row of spots on 

 the forewing which is wanting in A . indistincta, I have retained them as 

 distinct for the present.

" $ Upperside deep purplish black, the cilia cinereous. Underside 

 slightly paler. Forewing with a discal outwardly angled series of eight 

 pale violet-white dots, an even somewhat larger marginal lunular series. 

 Hindwing with a discal irregular series of pale violet-white spots, 

 within which are some obscure pale markings; a marginal series as in 

 the forewing. Cilia cinereous, marked with dark brown at the ends of 

 the nervules. 



Expanse: 1*15 inches. 



Habitat : Sikkim (Otto Mbllev and de Niceville.) 



This is a very distinct species." (de Niceville, I.e.) 



Also recorded from Sikkim by Mr. Elwes as rare. 



Mr. de Niceville states that this species is easily distinguished on the 

 wing from T. jhora and T. stigmata, which occur with it, by its much 

 larger size and deep black colour.
