Their behaviour fully bore out the sluggish character of the moth 
when at large, so well known to myself and a few others: we never 
once having seen it on the wing ; and thus in confinement, I noticed 
on every occasion they had never apparently shifted their position 
during the day, and only a little before dusk did they move quietly 
about ; just as on a similar occasion, when I had five moths together 
confined in a cage less than a foot square, where, by 11 p.m., two 
pairs were in cop., and separated next morning, without either having 
sustained injury worth mention. 
After the experience of 1S79, I looked forward to a still more 
successful rearing of the young larvae this season, but, in fact, I fared 
even worse than before, my per centage of loss being very distressing ; 
still, I am somewhat comforted to find the final result has not been 
entirely unsatisfactory ; and am yet hopeful of being in a position 
next season to supply my friends with this moth.

ADDITIONAL NOTES ON THE LARVA OF DEEP AN A SICULA. 
BY WILLIAM BUCKLEll. 
In Yol. xiv, pp. 1 — 4, of this Magazine is a description of the egg 
and the larva of sicula when first hatched, also of the fully matured 
larva, and I now offer a few more observations to fill up the hiatus in 
the early part of its history, that the perseverance and kind help of 
Mr. AY. TI. Grigg have enabled me to give, and to thank him herein 
for both larvae and ova. 
The eggs are laid by the parent moth on the very edges of the 
leaves, so that when hatched her progeny shall find themselves exactly 
where their food is most suitable ; for however much they may wander 
at first, it is there, in preference to any other part, the young larvae 
invariably begin to feed, on the cuticle of the upper surface ; there 
also they spin a small quantity of silk to rest upon and be secure 
while moulting. 
After a moult, while the larva is but little more than one-eigbth 
of an inch long, the future form is indicated, though the segments 
are strongly wrinkled and folded across at intervals, and the previous 
plain chocolate-brown colour is exchanged for russet-brown, relieved 
by minute dots and transverse bars of yellow. 
After the next moult, the larva begins to cut quite through the 
-ubstance of the leaves, eating out semicircular portions from the edge, 
t also begins to show on the brown ground-colour, little patches of
