Larvae and Pupae of South African Rhopalocera, 59 
piece of twig from the tree it feeds on, with thick “‘ mossy ” 
projections on every segment, the four next behind the 
head longer than the rest, and curved forward. It is rich 
olive-brown in colour, beautifully shaded, and it has one 
or two crimson dorsal spots; the three-cornered side piece 
is greyish-white, looking exactly like a small piece of 
lichen on the rough surface of the “twig”; the head is 
slate-grey. The pupae of these Psewdacraeae, which are 
suspended generally quite at the tip of extreme edge of a 
leat, are as follows :—P. tarquinia, long, thin, and _ boat- 
shaped, tapering to a point, and it is green in colour, some 
specimens being touched and outlined slightly with pink, 
P. imitator is also green, rather deeper in colour, and the 
shape is quite different, having two sharp, well-defined 
projections from that part which encloses the abdomen of 
the butterfly, while the pointed end is twisted and flat, 
and not so pointed as in P. tarquinia. The pupa of 
P. trimenii is much blunter and more substantial-looking 
than the other two, it is of a deep rich green, the abdomen 
portion frosted with white and very pale ochreous dashes ; 
about the centre of outline of wing-cases, is a dark, brown- 
madder rather elongated mark, surmounted and_ half 
surrounded by a suffusion of pale pinkish-brown, the tip 1s 
blunt, slightly turned up, and outlined with brown-madder.

(Plate X, figs. 12, 13.) 
I bred a good many of both these little butterflies, from 
ova laid by captive ¢¢. They are considered by Mr. 
Leigh to belong in all probability to the same species, 
and indeed I could never have separated their larvae if 
once mixed together ; in all stages they were exactly alike, 
and though in the last moult individually they vary 
enormously, I have bred both forms of the butterfly 
indiscriminately from every variety of the larva; against 
this, however, I must state, that as far as my experience 
goes, the ova ‘laid by ZL. hiarbas, always produced hzarbas, 
whereas those of a dryope 2 invariably produced dryope. 
The larvae of these butterflies in their early moults are 
dull, ochreous-white, with brown blotches here and there; 
when full-grown they are covered with short spines, and 
the two long antler projections on the head become more 
prominent; their colour now varies from bright green to 
brown, slightly mottled and streaked with yellow-ochre,
