ACIDALIA VIRGULARIA. 103 
on the dorsal region in front of each two simple leaf- 
like shapes of darkish brown, pointing backwards, 
united at their base but diverging near their tips, 
which end at the anterior pair of tubercular black 
dots; on the hinder part of each of these segments 
are equally wide dorsal shapes of brown, merged 
together at their base, but soon separating into Vs 
with double side strokes, the outer stroke of each pair 
being longer than the inner and reaching to the side, 
the central space between the inner strokes mostly 
filled up with the same brown colour until near the 
anterior pair of dots, where it fades away ; the poste- 
rior pair of black dots just within the outer strokes, 
and not far from the segmental division. Instances 
occur where these outer oblique dark strokes are 
margined a little way on their course by pale ashy or 
ochreous. ‘The ninth segment is paler than the others, 
and the tenth paler still; and on the back of the three 
hinder segments the markings are very simple rudi- 
ments of the preceding details. The sides are through- 
out clouded and streaked with darkish brown, and on 
the thoracic portion a strong dark brown line borders 
the pale subdorsal below; the spiracles are of the 
ground colour, ringed with darker brown. The belly 
of each segment is darkish grey-brown at the sides, 
with a paler ashy tinted pear-shape in the middle, out- 
lhned with dark brown, and on the narrowest part of 
this pear-like outline is placed on each side a conspi- 
cuous blackish spot; a whitish ashy stripe runs down 
the centre, widening at the end of each segment, and 
interruptedly outhned with blackish, most strongly 
at its widest part. 
The most noticeable variety among the larvee I had, 
was of a pale grey ground colour, in which the dorsal 
line could be distinctly traced throughout, though but 
little paler than the ground, and (as in many other 
species of Acidalia) was strongly bordered at the 
beginning of each segment with a short black mark 
(and this again, in one instance, with a white mark),
