454 Mr. R. M‘Lachlan’s Observations on 
made its appearance ; the last pupa likewise produced a male on 
the 28th; thus about a fortnight elapsed between the appearance 
of the first and last moths. The larvee were beautifully figured 
by Mr. W. Buckler of Emsworth, Hants (a copy of this figure is 
here given on P]. XXIII.), and have been most minutely described 
by Mr. Hellins in the “ Entomologists’ Monthly Magazine,” vol. 
ii. pp. 134,166. With respect to the moths produced from these 
eggs, I can only say that they show an extraordinary amount of 
variation inter se, and bear little resemblance to the parent moth, 
or to what has been always considered as the typical form of the 
species, and I have little hesitation in saying that had any one of 
them been taken at large, it would hardly have been referred to 
this species. I will describe them seriatim. 
No.1. ¢. (Pl. XXIII. fig. 2.) Anterior wings uniformly rosy- 
grey; the apical cilia rosy-pink; no discal spot; the oblique

apical margins, and with a well-defined central blackish-grey line ;

ish-yellow, suffused with rosy ; the apical cilia bright rosy, bor- 
dered by a narrow yellow line at the base ; a small purplish discal
