FIDONIA ATOMARIA. 141 
species, I did not at the time recognise them ; perhaps 
the locality of Wicken Fen diverted me from any 
suspicion of their being this heather-frequenting 
species. 
The larva was an inch or a little more in length, 
and moderately slender. The ground colour was a 
dull yellowish pale green, minutely freckled with 
brownish; this describes the dorsal stripe, which is 
edged with brownish and is relieved on either side by 
a yellow line; then there is another freckled stripe 
with darker edges similar to the dorsal stripe, and on 
this are the brown tubercular dots; the subdorsal line 
is yellow, and is followed by another stripe of 
brownish freckles, and then come three dark greenish 
or blackish very fine lines, followed immediately by the 
spiracular stripe of bright yellow; the spiracles at its 
upper margin are flesh-colour outlined with black ; 
the belly is similar in tint to the back, but has a broad 
paler central stripe edged with brownish, and a fine 
narrow line of the same on each side. ‘I'he head, anal 
segment, and anal legs are freckled with reddish or 
brownish-red. In this larva none of the lines are 
entire, but are composed of interrupted atoms.

FIDONIA BRUNNEATA. 
Plate CXXII, fig. 6. 
In October, 1867, Mr. Buckler sent me five eggs of 
this species, which had been kindly given to him by 
Dr. Buchanan White of Perth. On receiving them I 
examined them carefully under my microscope, and 
made the following description : 
The egg is oval in outline, but flattened, the upper 
side being even depressed in the middle; the whole 
surface covered with reticulations—generally hexagons, 
but some only pentagons, in shape; and at each angle
