i68 SOUTH- Al^T^ICAN BUTTERFLIES. 



ochreouSj with the dark borders only very slightly radiating on nervules 

 in the fore-wing, and not at all in the hind- wing ; while the gi'ound- 

 colour of the under side of hind-wing is uniformly dull creamy-fulvous, 

 with a whitish band immediately succeeding discal row of spots, and a 

 narrow, dentated, whitish hind-marginal edging. 



This species is local in its haunts, being almost confined to marshy or 

 swampy spots, but is usually in great abundance where it occurs. Early in 

 February 1859 it was on the wing in amazing numbers in the marshes border- 

 ing the Bitouw River at Plettenberg Bay on the southern coast of tlie Cape 

 Colony. It is in such damp places that the food-plant of its larva, a species of 

 Polygonum C? P. iomentosnm), flourishes ; and I learn from Mrs. Barber, who 

 discovered them, that the larvae abound on the plant in question, and that their 

 colouring resembles the pink and bronzy hues of the inflorescence. Tlie 

 butterfly has a slow flight, with a whirring action of the wings, and a tendency 

 to a circular direction; it always keeps near the ground, and settles very 

 frequently on low flowers. I believe that there are two broods in the year, 

 as I have found them numerously from the end of October to the middle or 

 nearly the end of ISTovember, and again from the middle of January to the 

 middle of March, but not in the intervening period.
