being generally a very muddy reddish-brown, but 
just after moulting almost black, the markings few 
and indistinct; the hinder segments are somewhat 
paler than the rest of the body; the segmental folds 
are darker; there is a paler dorsal line edged with 
black threads, which show most distinctly on the hind 
seoments ; and the dorsal ridges are paler than the 
ground. 
When full-fed the larve retired into some sandy 
soil to undergo their pupation. (John Hellins, July,

ACIDALIA VIRGULARIA. 
el Oe VI for 2: 
Lam indebted to Mr. J. H. Fletcher, of Worcester, for 
the opportunity of renewing my acquaintance with the 
larva of A. incanaria [virgularia of Stainton’s Manual]. 
Some eges kindly sent by him, loose in aquill, on the 26th 
of July, 1872, hatched on the 2nd of August following. 
The young larvee fed from the first on Polyqonwim 
aviculare, thriving so fast that one had changed to a 
pupa by the 3lst of August, several others by the 5th

pupation. The first moth appeared on the 14th of 
September, the others between the 26th of that month 
and the 8rd of October. 
The egg is of a rather long oval.shape, a little de- 
pressed on part of its surface, with the shell very

to brown two days before hatching. 
The young larve at first, and for some time, were 
of a pale ashy grey tint above, and darker grey 
beneath; resting often with their front segments 
curled under; at the end of a fortnight they were 
sufficiently grown to show their distinctive characters 
very well; at the end of another week varieties in
