438 LIEUT. -COL. C. SWINHOE ON LITTLE-KNOWN [June 17, 



from any of the species yet described, the embossed spot on the internal 

 area of the fore wings, peculiar to this group, is also very distinct, 

 and the transverse spot at the end of the cell is small and pale. 



Below, the general colour of both wings is pale orange-yellow, 

 with the inner border of the apex of the fore wings showing through 

 the wing, and a faint shade of a discal band on the hind wings ; other- 

 wise both wings are immaculate. 



5 . Above, ground-colour darker and yellower than the males, 

 irrorations at the base, the spot at end of the cell of fore wings, and the 

 black-brown markings on both wings generally paler and broader. 



Below, it has the general appearance of the male, but slightly 

 darker, with the addition of two pale- brown spots in the interno- 

 median interspace. 



Expanse of wings, S 2 2^^- to l^-^; inch. 



This is a very distinct species.

Group 7. Type Teracolus vestalis, Butler. 



8. Teracolus rorus, n. sp. (Plate XXXIX. S , fig- 8.) 



Sukkur (North Sind), February 1882. 



<S $ . Resemble on both surfaces the female of T. puellaris, 

 Butler, even to the third spot near the outer margin below being 

 extended downwards and expanding upon the inner margin, differing 

 not only in this from T. ochreipennis and T. intermissus (of which I 

 have many examples), but is larger, and the outer border of secon- 

 daries is much darker and deeper, fines down a little, and stops short 

 of the anal angle. I have examined a long series taken at the same 

 time and place.

As this group, of which T. vestalis is the type, is very indifferently 

 understood, it might be as well to give their distinctive character- 

 istics, which apparently never vary, and by which each of the follow- 

 ing species can readily be identifit-d : — 



T. vestalis, Butler. Below, both sexes, both wings sul|)hur- 

 yellow^ fore wings with three black spots near outer margin below 

 the median branches, the centre one the largest. 



T. ochreipennis, Butler. Below, both sexes with the three spots on 

 the fore wings as in T. vestalis ; hind wings in loth sexes flesh- 

 colour, marginal border of the hind wings above unmarked and like 

 2'. vestalis. 



T. intermissus, Butler, P. Z. S. 1883, p. 152, pi. xxiv. fig. 4. 

 Similar to T. ochreipennis below ; above, the marginal band of 

 the hind wings is narrow and wavy. 



T, puellaris, Butler. Below, fore wings with the lowest of the 

 three spots extending downwards and expanding upon the inner 

 margin in both sexes. 



(S . Both wings below sulphur-yellow. 



$ . Eore wings below sulphur-yellow, hind wings flesh-colour.
