3. Gadirtha albovenosa sp. nov. (pi. XIII, fig. 3). 

 $ , 49 mm. 



Antenna with fasciculate cilia to fully two-thirds of shaft, the cilia 

 much curved, but, if straightened, would apparently be three or four 

 times diameter of shaft; probably belongs to Section I of Hampson. 

 Segment 3 of palpus nearly as long as. segment 2, with strong rounded 

 thickening at extremity. 



Head, tegulae, thorax, palpus and antennal shaft dark brown, the 

 tegulae with some paler, greenish- grey scales, the patagia with dark 

 purplish-brown scaling ; abdomen above and beneath, pectus and legs, 

 dark brownish-grey, the legs with some browner shades. 



Fore wing deep glossy brown, tinged in parts with ochraceous- or 

 purplish-brown, and with a greenish shade along SC; markings blackish, 

 rather obscure, with the exception of a silvery-grey apical spot, a 

 sharply defined white subterminal line (bent outward at SC 5 and 

 slightly angled inward behind R'),a white streak along distal two-thirds 

 of hindmargin, pure white streaks to termen, on vein SC 5 from sub- 

 terminal line, on R 1 and M 2 from postmedial, on K 2 and M 1 from their 

 origin and on SM 2 from base, a fine white streak in fold from base to 

 middle of wing and a diffused white medial streak from fold to hind- 

 margin. Subbasal line double, strongly excurved from costa to M, 

 thence almost obsolete ; antemedial line triple, oblique and waved, from 

 about two-fifths costa to one-third hindmargin, the proximal line 

 diffused ; reniform somewhat as in inexacta Wlkr. (xiii, 1102 [1857] 

 [Burma]), but more (irregularly) rectangular and without point on 

 distal edge ; postmedial line treble, somewhat as in exacta Semper 

 (" Reise Phil., Schmett.," ii, p. 527, pi. lx, t. 6 [1900] [Philippines]), 

 but evenly curved (not dentate), angled outward from behind M 1 ; a row 

 of proximally brown-edged interneural black terminal spots : fringe 

 with some pale reddish-brown shading round the white neural streaks, 

 which are continued on to the fringe. 



Hind wing somewhat as in exacta but less contrasted (proximally 

 more tinged with grey), with a stronger dark spot at inner angle, and 

 with a straight (very slightly waved) dark postmedial line from about 

 R 1 to hindmargin. 



Fore wing beneath nearly uniform greyish-brown, except for the 

 usual pale inner area ; hind wing whiter, with slight brownish-grey
