14. IxiAs FREQUENS, B. sp. (Plate XV. figs. 6, 7.) 



c?. Above very similar to the preceding, but the orange belt of 

 primaries more regular in outline and slightly yellower, basal area 

 darker ; secondaries with a broader and internally diffused outer 

 border : wings below clearer, not mottled, the apical area of prima- 

 ries slightly dusted with grey scales ; veins terminating in minute 

 black dots, and similar dots on the angle of the discocellulars. 

 Expanse of wings 2 inches 4 lines. 



2 • Above bright lemon-yellow, the basal area heavily irrorated 

 with grey and brown scales : primaries with the costal border and 

 apical half black-brown, the latter crossed by a rather broad zigzag 

 pale orange belt bordered with yellow and crossed by black veins, 

 separated at the third median branch, below which it is crossed by 

 two black spots, the lower one confluent with the blackish ground- 

 colour : secondaries with broader outer border than in the male. 

 Wings below altogether different: primaries sulphur-yellow, sprinkled, 

 especially upon apical area, with brown scales ; a large dark brown 

 discocellular spot crossed by a yellow vein ; a discal series of six 

 spots, the three upper ones placed obliquely, pale brown with whitish 

 pupils, the others black ; a large blackish patch at external angle : 

 secondaries pale sulphur-yellow, sparsely sprinkled on basal area 

 with black scales ; external area irrorated with brown ; veins termi- 

 nating in black dots ; a small black spot on the angle of the disco- 

 cellulars ; a discal series of seven unequal spots in an arched series, 

 pale reddish brown with white centres ; venter white. Expanse of 

 wings 2 inches 3 lines. 

 Bengal. 



15. IxiAs WATTi, n. sp. (Plate XV. fig. 1.) 



Also allied to I. dharmsalce, but the base more densely obscured 

 by blackish scales ; the orange belt narrower and of a deeper colour : 

 secondaries with the outer border wider, diffused and broken up by 

 yellow internervular folds into large spots ; body blacker. Wings 

 below sulphur-yellow, sparsely irrorated with blackish scales, with 

 small black discocellular and marginal dots : primaries showing 

 traces of the orange belt through the wing ; two brown dots placed 

 obliquely beyond it upon the subcostal interspaces : secondaries with 

 a discal series of seven saffron-yellow spots in an arched line, the 

 fourth largest. Expanse of wings 2 inches 5 lines. 



Bengal. 



The following species was taken by Dr. Watt during a recent ex- 

 cursion into Thibet : — 



16. EucHLOE vENOSA, n. sp. (Plate XV. fig. 5.) 



(S . Allied to E. daphalis, which it much resembles above, except- 

 ing that it is considerably larger, has the apical area of primaries 

 darker and the white spots consequently better defined, the discocel- 

 lular spots decidedly larger and the markings of the under surface 

 more distinctly visible through the secondaries. Below it is quite
