i ACIDALIA MARGINEPUNCTATA. 
the black dots and Vs are strongest and most notice- 
able on the end of the fifth segment; on the thoracic 
segments the markings are linear and darkish grey, 
as they also are on the last four; the inflated ridge is 
very dark grey, freckled; the belly suffused with a 
sooty blackness, excepting a narrow grey transverse 
band at each segmental division, the sides of the last 
four segments being a little paler, of a grey colour; 
two black central or twin lines can be seen on the 
narrow grey transverse band. ‘The colour of the head 
is dirty whitish, broadly marked with blackish down 
the front and side of each lobe. When full-grown 
(June 22nd) the ventral surface is black only beneath 
the inflated spiracular ridge, the rest being grey with 
two central undulating stripes followed on either side 
by another of blackish-grey. One of my two examples 
became quite white in ground colour on the back of 
the eighth, ninth, and front part of the tenth sezments, 
the pale grey of the thoracic segments gradually 
becoming whiter, on the last three segments dark 
erey as before. The first ashy-grey larva retained its 
colouring in all respects until it retired for pupation 
on the 26th of June. 
The other larva on the 3rd of July spun some few 
silken threads amongst its food-plant, and remained to 
pupate there. 
The perfect insects appeared on the 27th July and 
5th August, 1874. (William Buckler, August, 1874 ;- 
Note Book IT, 74.) 
For the opportunity of studying the history of A. 
straminata, the larva of which, I believe, is hitherto 
undescribed, | am indebted to the kindness of Mr. 
GB: Corbin, of Ringwood, who sent me eggs with 
the female moth on July 23rd, 1873. 
The eggs are rather large for the size of the moth, 
oblong-square with the corners rounded, in colour 
reddish-brown, —deposited loose; they hatched on 
the 29th of the same month, and the newly emerged 
larvee are long and slender,—in colour a very dark
