Crypsotidia gen. nov. 



Foreivings : narrow, elongate ; costa straight, convex only at apex, which 

 is blunt ; hindmargin vertical above, curved below. 



Hindwings : with hindmargin slightlj' indented below apex, and truncate 

 at anal angle. 



Antennae of 3 simple, pubescent (shortly ciliated) ; palpi thick, semi- 

 decumbent, rough-haired, the third joint small. Tongae and frenulum wull 

 developed. 



A tuft of hairs from beneath base of costa of forcwings, and from basal 

 segment of the abdomen, close to base of hindwiug, a small chitinous fringed 

 flap, not connected with the hindwing. 



Neuratioii : forewings, cell more than half the length of wing ; first median 

 nervnle at three-ijuarters, second median close before third, lower radial from 

 close above it ; ujiper radial from upper angle of cell ; vein 7 from just before 

 angle, upcnrved at origin ; 8, 9, 10 stalked, the stalk of 8, 9 closely approximated 

 but not touching 7 ; 11 free. Hindwings : 8 anastomosing with cell for half 

 its length, 7 from before up)ier angle ; first median at four-fifths, second from 

 end of cell, third median and the radial stalked. 



Type : ( 'ri/psotiilia wollastoni, sp. nov. 



37. Crypsotidia wollastoni sp. nov. 



One S, 17. ii. 1901. Shendi. 

 A single example at light. 



Forewings : pale greyish ochreons faintly rufous-tinged, becoming greyish 

 fuscous towards hindmargin ; first Ime very indistinct, from before one-third 

 of costa, where it is marked by a black dot, to near middle of inner margin ; 

 oblique to the median vein, then vertical, hardly paler tlian the ground colour ; 

 outer line blackish, edged with paler, from costa at three-fifths, strongly outcnrved 

 round cell, and as strongly incurved below lower end of cell, then vertical and 

 sinuous to inner margin beyond middle ; space between the two lines from inner 

 margin to median vein greyish fuscous ; an indistinct patch of dark scales at 

 end of cell ; submarginal line irregularly waved, emphasised by the preceding 

 greyish fuscous shade, which at costa forms a velvety black blotch, the pale 

 submarginal line itself expanding into a bone-coloured triangular subapical 

 blotch ; small wedge-shajicd black marginal spots between tlie veins, each followed 

 by a pale dot ; fringe greyish fuscous. 



Jlimlwings : semi-transparent, pearly white, tinged with dark grey along 

 hindmargin ; fringe white. 



Underside white ; the costal area in both wings straw-coloured, and their 

 apices blackish fuscous ; in the forewings the outer edge of the black subcostal 

 blotch is marked with black, and a black dot indicates the commencement of 

 the outer line on costa. Head, thorax and abdomen like forewings, the abdomen 

 being rather lighter and the prothorax darker ; the paljii and lower part of 

 face dusted witli dark fuscous. 

 Expanse of wings : 26 mm. 

 This species is named in honour of my friend Mr. A. F. R. Wollaston.
