174 MESSES. H. J. ELWES AND JAMES EDWARDS: 



termen between veins 5 and 6 reaching a little beyond the actual tip ; hind wing 

 rounded, its greatest length not exceeding that of the dorsum of the fore wing- 

 Abdomen comparatively long and slender. On the hind wing below the common 

 pattern consists of the following spots of pale scales, namely : — one in cell 7 erect from 

 the base of vein 7, one near the middle of the upper margin of the cell, one in the 

 basal third of cell 6, and four in a straight line almost parallel with the termen, 

 one each in cells 2, 3, 4, 5 ; some of these spots are sometimes suppressed, and in some 

 specimens the whole are scarcely discernible. 



Two species are mentioned by Watson (P. Z. S. 1893, p. 87), which may be 

 distinguished as follows : — 



Sex-mark present in the male. Hind wing below with pale spots or bandsj or 



both pulligo, Mab. 



Sex-mark wanting in the male. Hind wing below unmarked fusciila, Snell. 



Watson says of S. fuscula that the male mark is present, but inconspicuous, and he 

 separates the species from 8. pulligo by having the underside of the hind wing entirely 

 unmarked, and by the beautiful plum-like bloom of the upperside, though this last 

 character is only apparent in fresh specimens.

A genus of few species, well exemplified by the Astictopterus xanites of Butler. 

 Apart from fades, it differs from Suastus and lamhrix in the fact that vein 11 of the 

 fore wing touches or anastomoses with vein 12 for a portion of its length. Perhaps the
