This appears to be near T. nysa. I have not seen a specimen, 

 and it seems a rather doubtful species. 



5Q. Thyca orpline, n. sp. (PI. VIII. fig. 3, $ .) 



Form of the Aspasin group of Picris. Male. — Above, white, with 

 the base dusky ; upper wings with a narrow black border from the 

 ajiex to near the outer angle, the costa dusky, as well as the extremity 

 of the cell, and a broad marginal band beyond as if smeared with 

 black ; the lower wings have a very narrow dusky edging behind. 

 Beneath : the uppers have the base dusky, a broad patch at the 

 end of the cell nearly black, and a broad dusky outer margin, en- 

 closing a row of six white spots, the two lower the largest ; lower 

 wings black, but nearly covered with chrome-yellow, which covers 

 the whole abdominal margin to the middle of the wing, beyond 

 which are three large oval spots near the outer angle ; another 

 band of yellow crosses the lower half of the cell, and reaches up 

 to the inner margin near the base of the wing. 



Expanse of wings 2| inches. 



JEfa6.— Malacca (Mount Ophir) (Coll. Wall.). 



This curious species is rather difficult to locate. Its neuratlon 

 shows it to belong to the genus IVnjca, and it seems best placed 

 near nysa and momea on account of its black under wings beneath, 

 although the amount of yellow with which it is adorned gives 

 it a different aspect.

Moh. — Luzon, Philippines (Coll. Felder). 



Judging by the form of the wings and the style of colouration, 

 this species is allied to T. orphne, and comes in the nysa group.
