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 1879, 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 LAEVA OF DREPANA SICULA. 

 BY WILLIAM BUCKLER. 



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. W. H. G-rigg have enabled me to give, and to thank him herein j 

 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-eighth, 

 of an inch long, the future form is indicated, though the segments;! 

 are strongly wrinkled and folded across at intervals, and the previouPiJ 

 plain chocolate-brown colour is exchanged for russet-brown, relieved I 

 by minute dots and transverse bars of yellow. 



After the next moult, the larva begins to cut quite through the 

 substance of the leaves, eating out semicircular portions from the edge, 

 it also begins to show on the brown ground-colour, little patches of
