and the basal area broadly, suffused, with greyish-white scales. 

 Hind-wing brown ; the outer-marginal area orange and the inner- 

 marginal and basal areas suffused with greyish-white. An outer- 

 marginal series of pale-blue patches placed on the nervules, which 

 are brown. Cilia of both wings pale-brown. Under-side pale 

 brown sprinkled with white scales ; fore-wing with the discal 

 area orange and a short band placed beyond the cell, composed of 

 three confluent dark brown spots much as in T. quadriinaculatay 

 Hew., but nearer to the apex. Hind- wing with an ultra-median 

 linear dark brown irregular band commencing on the costa and 

 reaching to the inner margin. Cilia grey. 



9 . Upper-side brown with the median interspaces of the discal 

 area brownish-orange. Hind -wing brown with the inner-marginal 

 areas slightly dusted with blnish-white scales and a submarginal 

 row of rather large dark brown spots inwardly crowned with orange. 

 Under-side paler than in ^, the short band on fore- wing placed

Dififers from T. quadrimaculata, Hew.,* and its allies by 

 the $ wanting the prominent patch of dark scales at the 

 end of the cell of the fore-wing, and by the whitish shining 

 basal areas on the upper-side. 



Although the under-sides of the two specimens described 

 present considerable differences, I think there is no doubt 

 that they are sexes of one species.
