250 SOUTH- AFRICAN BUTTERFLIES. 



tubercles grow longer, and the ground colour changes from greenisli- 

 brown to greenish, and the white markings grow less distinct. 



" Full-grown Larva. — Bluish-green, like larva of PliUognoma Va~ 

 ranes. 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. I5 to i|- inch long." 



"feeds on Vcpris 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 sj)ot, 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. 3^ 

 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 pujite forwarded by Mr. J. P. Mansel Weale 

 from the neighbourhood of King William's Towni.) 



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
