SOUTH-AFRICAN BUTTERFLIES, 
oclireons, with the dark borders only very slightly radiating on nervules 
in the fore-wing, and not at all in the hind- wing ; while the ground- 
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 os the so'uthern coast of the Cape 
Colony. It is in such damp places that the food-plant of its larva, a species of 
Polygonum (1 P. tomentosum), flourishes ] and I learn from Mrs. Barber, who 
discovered them, that the larvse abound on the plant in question, and that their 
colouring resembles the pink and bronzy hues of the inflorescence. The 
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 November, and again from the middle of January to the 
middle of March, but not in the intervening period.
