curved, but whether this is natural or due to the immersion 
in the preservative fluid cannot at present be decided. 
The whole larva has a very ‘“* Lymantrid” appearance, 
and the presence of urticating spicules on a Rhopalocerous 
larva is a very remarkable feature. Farquharson describes 
the larva as brightly pigmented with red, green, and yellow, 
and perhaps other colours, such ‘as one associates with 
Lymantrid caterpillars. Length of larva 18 mm. Farqu-

Pupa. The extraordinary pupa, shown at fig. 9, is attached 
by the terminal segments to its support, and the remains 
of the larval skin form a cushion of radiating hairs. On 
the 5th and 6th abdominal segments there is a conspicuous 
dorsal patch of yellowish brown, and a similar one just 
behind the head. The whole thoracic and dorsal surfaces 
are densely covered with elaborate chitinanths, which in 
many places are white. The effect of this is very peculiar. 
It gives the pupa the appearance of being mouldy, a fact 
to which I called attention before I knew that Farquharson 
had observed the same appearance in nature (p. 340.) Until 
I examined the pupa microscopically I quite thought it was 
mould, and that the specimens would have to be cleaned. 
In addition to the general covering by these structures, 
there arise from various points long branched filamentous 
chitinanths as shown in the figure. These add to the 
mouldy appearance. Length 15mm. J emerged 9.12.17,

Pupa. As will be seen from fig. 10, the shape of this 
pupa is quite unusual, its form gradually widening from the 
posterior to the anterior end. The cuticle is covered with 
chitinanths both stellate and annular, and also with long 
delicate filaments bearing plume-like expansions at their 
extremities. A small portion of the cuticle is shown at 
fig. 6 highly magnified. From the terminal extremities 
project tufts of long hairs which blend with those of the 
larval skin, forming a dense cushion at the point of attach- 
ment. The pupa hes flat with the ventral surface in con- 
tact with the bark. The larva was evidently clothed with 
silky hairs. There is a considerable quantity of silk on 
the bark, round the pupa, forming a kind of elementary 
cocoon. Length 12 mm. The example figured produced
