SOUTH-AFRICAN BUTTERFLIES. 
Length |- inch ; greatest width (across base of abdomen and wing- 
covers) ^ inch. 
(Described from a King William's Town example sent to me by 
Mr. Mansel Weale, from which the imago emerged on 24th March 
1873.) 
I have also reared a $ imago from a similar pupa received from 
Colonel Bowker (D'Urban, Natal) in March 1881. 
Plate II. fig. 6a. 
Mr. Weale wrote in 1873 that his Rohinia trees at Brooklyn, near King 
William's Town, were covered with the larvae of Forestan^ which completely 
riddled the clusters of leaves within which they fed. 
This well-known species appears to range throughout the Ethiopian Region. 
Its .closest ally, which accompanies it in Madagascar and Reunion, is ArhogasteSy 
Guen. { = Margarita, Butl.),^ hut it is also very nearly related to Pisistratus^ 
Fab., which has a similarly wide continental distribution, but does not seem to 
occur in Madagascar or the Mascarene Islands. In South Africa it inhabits 
only the eastern side, not having, to my knowledge, been taken westward of 
Port Elizabeth, and is commoner on the Natal coast than elsewhere. In 
January and February 1867 I took a good many examples about DUrban; 
and also met with the species in Mauritius in July 1865, and near Grahams- 
town in February 1870. Its flight is very swift, but hiistUng, reminding one 
of that of the Phisice and other diurnal members of the Noctuse tribe ; it keeps 
steadily to flowers (in Natal preferring the cultivated Lantana), appearing both 
in the heat of the day and a little after sunset. The wings are elevated when 
the insect is settled, the hind-wings being held slightly apart from the fore- 
wings.

^ Figured in Grandidier, Rist. Madag., xix. Atlas, pi. 51, ff. 5, 5a (1885), and distin- 
guished by its sub-metallic greenish-grey basal suffusion on the upper side (shading off into 
hoary-grey in hind-wings), and inferiorly much narrower white band on the under side of 
the hind-wings.
