and not reachiug sides ; both these spots narrowly bisected longi- 

 tudinally by a pale space. Pubescence of dorsum mainly following 

 ground-colour, but whitish or pale yellowish at sides, and over 

 all the 4th segment and the nearly all yellowish venter. Legs 

 orange-yellow ; apical half of anterior femora, apical three-fourths 

 of hind pair, and nearly the whole of all the tibite, black ; 

 all knees narrowly pale ; all tarsi brovvnish-yellovv, tips darker, 

 especially in the fore pair. Pubescence of legs Avhitish but black 

 on hind tarsi. Wings pale yellowish-grey ; stigma ill-defined but 

 moderately dark brown, the subcostal cell thence to its tip yellow; 

 a small brown elongate ill-defined spot over tip of 1st basal cell.

Described from 3 ^ $ in Indian Museum. Kasauli, 29. vi. 1905 

 (Barroiv) ; Kurseong, 5000 ft., 3. vii. 1908 (Annandale) ; Sadiya, 

 Assam, 27. xi. 1911 (tgpe of nigripes) (Kemj)) ; other examples 

 from Kurseong, 5000 ft. {Annandale)-, Grangtok, Sikkim, 6150ft., 

 9. ix. 1909 ; above Tura, Garo Hills, Assam, 3500-3900 ft., 

 15. vii.-30. viii. 1917 {Kemp). 



In the typical form of ventrcdis the yellow colour of the face is 

 carried narrowly along the eye-margins of the Irons to the vertex ; 

 the sides of the thoracic dorsum are narrowly yellow and there is 

 considerably more yellow on the pleura?. The pubescence towards 

 the hind margin of the dorsum is yellow, and the bristles there all 

 yellow. The femora are mainly orange, but tinged indefinitely 

 with brown on the apical half: the hind tibiae have whitish, not 

 black, pubescence, and all the tarsi have more orange in them than 

 iu the variety nigripes. 



Differing from angustimarginata, Brun., by the yellow coxse, 

 the almost wholly black front tibiae and yellowish fore metatarsi, 

 the broadly black ringed middle femora and nearly wholly black 

 middle tarsi, the larger amount of black in the hind legs, and the 

 pale grey basal part of the wing, with the inner end of the stigma 

 conspicuously black. 



Only one specimen of the typical form has been seen by me : 

 a $ from Eotung, Abor Expedition, 1400 ft., 26. xii.1911 {kemp). 

 The species was originally described from Java, and De Meijere 

 records it from Buitenzorg. The coloration of the legs and of 

 the chsetotaxic bristles appears to be distinctly variable.
