178 SOUTH- AFRICAN BUTTERFLIES. 
the Var. Capensis as a separate form, all the specimens that I have 
seen from that territory presenting only the almost linear rudiment of 
the dark border of the fore-wing ; but in Natal, Transvaal, and Delagoa 
Bay the insect has the border more or less developed, being in the 
last-named locality identical with the Var. Mossamhicensis. Two Trans- 
vaal specimens in the British Museum and five Natal examples in the 
South- African Museum present a complete gradation between the Vars. 
Capensis and Mossamhicensis, which latter is scarcely separable from 
Congo Buquetii. The only examples that I have seen from Damara- 
land, viz., a $ taken by the late Mr. Andersson and a small yellowish 
$ in the Hewitson Collection, both have the border moderately broad 
and ending about first median nervule. From the Zambesi, two ^^s 
have the border black and broad, while in a $ it is dusky and nar- 
rower; and Oberthiir notes that Zanzibar examples are like the type 
from Senegal. It is noticeable that the broad-bordered typical 
Bicqicetii has the under side greener in tint, more glossy, and less dis- 
tinctly irrorated and striolated, with the terminal disco-cellular spot i 
of the hind-wiuGjs narrower and less rounded. 
I have not seen the Var. Ambica, but it is clear from Hopffer's 
account that only the apex of the fore- wings is dusky-blackish, while 
Butler's description of the under side applies very nearly to that of 
the type-form. A small $ from Madagascar in the South-African 
Museum is intermediate between this variety and Mossamhicensis, the 
narrow border extending on hind-margin only a little below second 
median nervule. | 
As Doubleday (Ge7i. D. Lep.^ i. p. 65) has remarked, this plainly-tinted 
Urania both in colour and marking bears a strong resemblance to the white 
species of Callidrijas; and Cape specimens are so like C. Florella, (Fab.), both in 
appearance and flight, that it is very difficult to distinguish the two before capture. 
Wooded spots and gardens in their near neighbourhood are the favoured 
haunts of Buquetii^ which appears at the end of January and remains out 
until the middle of April. At Plettenberg Bay and near Graliamstown I met 
with the ^ abundantly, but $ s were scarce ; the flowers of Plumbago were 
their constant resort. They are remarkably swift on the wing, and their halt 
on a flower is exceedingly short. At Port Elizabeth I took one specimen 
and saw another at flowers of Agapanthus. Very rarely I have met with a 
straggler in the neighbourhood of Cape Town during the later summer months. 
I did not notice the species during my stay in Natal ; and the few individuals 
I have received from that Colony were taken near Maritzburg.^

1 In the first week of February 1889, Mr. A. D. Millar met with about a dozen speci- 
mens near D'Urban, and captured seven of them. These examples have the blackish border 
moderately developed.
