wings than the others; a not very distinct marginal series. Hinc*mn$ 

 with several large spots at the base, a very large one at the end oi the 

 cell, a very irregular discal series, and a marginal series as in the 

 forewing. Antennae, head, and body fuscous. Female. Much as in 

 the male, except that the third median nervule of the forewing is not 

 basally swollen, and the hindwing is highly scalloped instead of being 

 almost entire. 



An apparently quite distinct species. It is, perhaps, nearest to the 

 common P. horsfieldi, Moore, which also occurs in North-East Sumatra, 

 but the coloration of the upperside is darker, and the ground-colour 

 and shade of the spots of the underside are very different, the former 

 being pure white, the latter sepia, while in P. horsfieldi the former is 

 pale ferruginous,* the latter dark ferruginous. The hindwing in 

 the male of P. pcetus is but very slightly scolloped, but this is a most 

 remarkably inconstant character, especially in the females, of 

 P. horsfieldi. The upper discoidal nervule is given off from the sub- 

 costal nervure far beyond the apex of the cell in the male, at the apex 

 in the female. P. panormis, Elwes,f described from Burma and 

 Perak, also occurs in North-East Sumatra, but it is a very distinct 

 species. 



Described from two males and a female in my collection, captured 

 at Bekantschan in March and November, and numerous examples in 

 the collection of Hofrath Dr. L. Martin.
