yellow ; and sometimes the hind wing is much paler in tint than the 

 fore wing. Although a very common species in open grassy, flowery 

 places on the borders of the forest, I never detected it in eapuld. 

 The male, however, I believe to be an insect scarcely distinguishable, 

 except by its smaller size, from the same sex of T. Deva, as described 

 above.

T. venusta, Bdv. Sp. Gen. 658. 8. 

 This species very much resembles T. Nise $ , but is smaller in size. 

 It is taken in company with that species, and is probably a mere 

 variety of it.

2- Wings rounded. Above: fore wing clear yellow, costal border 

 sprinkled with dusky atoms ; an outer border, beginning about the middle 

 of the costa, and terminating in a point at the hind angle, multisinuate 

 on the inner side, violet-black : hind wing white, with a yellowish tinge ; 

 outer margin near the apex broadly dusky, through which the nervures 

 appear of a darker colour. Beneath : fore wing whitish, the costal border 

 and apical third ochreous-red, disk yellow ; hind wing ochreous-red, with 

 an undulated line across the wing darker, and two spots at the end of the 

 wing-cell black. 



According to Cramer's figure of the 3 , the under surface of the 

 wings is of an ochreous-red hue, with dusky marks, and the upper 

 surface has an abbreviated posterior black stripe on the fore wing. I 

 met with numerous 3 individuals agreeing with this type, and in 

 company with them numerous $ conformable to the description 

 given above. Boisduval in his description (Sp. Ge'n. 664. 19) has 

 mingled this form with one or two others, probably distinct species, 

 and amongst them the following.

$ . Very similar in size and shape to Elathea $ . Above : fore wing 

 very pale whitish-yellow, costal border broadly dusky ; outer border very 

 broad, especially on the costa, terminating rather broadly at the hind 

 angle, multisinuate within, violet-black : hind wing white, outer border 

 very broad, irregular, black, terminating long before reaching the anal 

 angle. Beneath : white ; fore wing with the fore part and apex bright 

 yellow ; hind wing sprinkled with dusky atoms. 



The 3 is distinguishable from the same sex of Elathea by the under- 

 surface being pearly white, slightly sprinkled with dusky atoms, and by
