SOUTH-AFRICAN BUTTERFLIES. 
tubercles grow longer, and the ground colour changes from greenish- 
brown to greenish, and the white markings grow less distinct. 
" Full-grown Larva. — Bluish-green, like larva of Fhilognoma Va- 
rams. Tubercles very short, those next head yellowish, on anal segment 
whitish ; very much like a slug in shape. Y-like organ crimson-lake at 
base, tapering to greenish-white. On fourth segment, two small black 
spots, bordered by a narrow white line ; sixth and seventh segments 
festooned with delicate whitish zigzag lines. A double row of bluish- 
white dots along back. Lateral borders above spiracles white. Head 
and true legs green, false legs pale-ochreous. to if inch long." 
" Feeds on Vepris lanccolata^ — J. P. Mansel Weale. 
Pupa. — Anteriorly much attenuated, but about middle greatly ex- 
panded laterally; posteriorly tapering rather abruptly to a point. 
Inferior side strongly convex, especially about broadest part of wing- 
covers ; superior side moderately concave from tail to disco-thoracic 
prominence, which is acute but not much elevated ; lateral line along 
expansion forming a thin sharp ridge. Head very prominent ; the two 
ordinary points not being divergent, but directed straight forward with 
their inner edges closely contiguous, so as to form a single forward pro- 
jection tapering together to one point. 
Bright yellowish-green on back and rather dull-green on under 
side. Along back, a median whitish-ferruginous streak, commencing 
with a small spot on thoracic elevation, and gradually becoming slightly 
wider and better defined until it reaches anal extremity. On each 
side of this streak on fifth abdominal segment, a subquadrate reddish- 
white spot, external to which is a dot of the same colour (the second 
and most apparent in a longitudinal row of four). Expansion of lateral 
margin bounded by yellow (here and there varied with whitish-ferru- 
ginous) along the ridge separating the dorsal and ventral aspects, from 
head to tail. Spiracles situated just above this thin lateral ridge. On 
ventral aspect a narrow longitudinal yellow streak defines the line of 
the median convex ridge. On wing-covers, besides some very fine pale 
lines indicating the neuration, some similar transverse lines on each 
side of median streak. On sixth segment of abdomen, on each side of 
median streak, a sub-ovate whitish ferruginous spot. Length, i in. ^\ 
and I in. 4-|- lin. ; greatest width (across third abdominal segment) 6 
lin. ; greatest depth (at junction of second and third abdominal seg- 
ments) from breast to back 4 lin. and 5 lin. 
(Described from two pupse forwarded by Mr. J. P. Mansel Weale 
from the neighbourhood of King William's Town.) 
Mr. Weale {loc. cit., p. 134) observes " that the larva about to 
pupate generally fixes its anal legs below the axil of a leaf-stalk, and 
fastens itself below sixth " [actually metathoracic] " segment with a 
double thread to the petiole." In this position the ventral or under 
side of the pupa, which is darker than the dorsal or upper side, is
