of which the right is larger than the left. The tegumen is symmetrical in both 

 species, and the clasps are so in pandita ; but in the clasps of masuriensis the 

 asymmetry is extreme. 



The species here included in the genus may be distinguished as follows : — 



1 (4). Fore wing with hyaline spots in cells 6, 7, 8. Hind wing 



below not marked with about ten black spots. 



2 (3). Upperside dark brown with a purple shade, pale spots on the 



fore wing pure white. Hind wing below grey-brown, generally 



with a minute pale spot in each of cells 2 and 3 ; fringe white . . masuriensis, Moore. 



3 (2). Upperside brown, pale spots on the foi'e wing sordid yellowish 



white. Hind wing below yellow-brown ; fringe brownish grey . pandita, de Nicev. 



4 (1). Fore wing without hyaline spots in cells 6, 7, and 8, or with one in 



cell 6 only. Hind wing below marked with about ten black 

 spots. 



5 (6). Fore wing with no pale spot in cell 6. Fringes of hind wing below 



pale, with dark spots next the veins. Male with the long hairs 

 near the base of the hind wing above normal, not forming a tuft. 

 Apex of tegumen (viewed from above) elongate-triangular, with 

 a short horn on each side of the base maculicornis , n. sp. 



6 (5). Fore wing with a pale spot in cell 6. Fringes of hind wing below 



pale with the basal half dark. Male with a distinct tuft of 

 subequal long hairs near the base of hind wing above. Apex of 

 tegumen (viewed from above) elongate-triangnlar, with an ear- 

 like lobe ou each side of the base / uscicornis, n. sp.

<S . Upperside dark umber-brown : fore wing with four yellowish-white hyaline 

 spots — one large, occupying the prebasal fifth of cell 2, one occupying the prebasal

 cell 3 and one on the upper edge near the base of cell 9 ; a streak of golden-yellow 

 scales along the costa from the base to near the middle and another along the
