164 OPORABIA FILIGRAMMARIA. 
the belly itself is less pale but whitish-green, quite a 
contrast with that of the back and sides. 
On the 29th I received two more larve a little 
larger, about three-quarters of an inch long, of a rich 
dark olive-brownish velvety green, with bright yellow 
ragged lines, the upper two lines deeper yellow than 
the spiracular line; and on the 7th of June I received 
from Mr. Kay fourteen more larve, most of them 
very small, and all obtained from heather of a darker 
hue than this plant is in the south of Hngland ; and 
although they fed quite greedily on sallow, weeping 
willow, etc., yet they preferred to retire to the heather 
until they were nearly full-fed ; with which plant their 
colouring was in harmony, and it is noticeable that 
after dieting on sallow their colouring became per- 
ceptibly lighter than before. Many of them died on 
the earth in an aborted pupa state, others in the larva 
state shrivelled, one was ichneumoned, a few spun a 
few threads amongst twigs of heather and pupated 
within them, and a few entered the earth and therein 
made slight cocoons, but holding tolerably well 
together. , | 
Five moths in all were bred, viz. one g and two 
?son the 2lst of August, one ¢ on the 24th, and 
one $ on the 8th of September. 
The pupa is three-eighths of an inch long, of rather 
dumpy figure, but not otherwise remarkable, the abdo- 
minal segments tapering to the tip, which is furnished 
with a small tapering spike having two minute 
diverging hooks at the fine extremity, and its colour 
is very dark brown with rather a glossy surface. 
In 1882 I received on the 26th February, from the 
Rev. J. Hellins six larvee from eggs laid by one of the 
9 O. fiigrammaria mentioned above that I had for- 
warded to him at the time they were laid on leno. 
These larvee were of different sizes, large and small, 
reared on rose-leaves and whitethorn. The largest 
one at this date (February 26th) was 18 mm. long and 
in its last stage, extremely dark velvety olive-brown,
