BOARMIA ABIETARIA. DA 
of October, and lasted in a very partial way until the 
following spring, as they frequently moved a litle, 
and nibbled their food during that period; at the 
end of March, 1877, they fairly waked up, began to 
moult and thrive, and the most forward individual 
attained full growth by the 21st April, entering the 
earth on the 28th, and followed by the others at in- 
tervals up tothe 9th May. ‘The moths, ten in number, 
v. €, elght males and two females, and all finely 
developed, were bred from the 8th to 21st June. 
The egg in shape is oblong, elliptical, and has a 
depression on some part of the side, its surface finely 
ribbed lengthwise and pitted between the ribs; the 
colour a light subdued green, glistening with a pearly 
lustre, changing on the seventh day to a paler tint of 
ereenish-drab, and again on the fourteenth day to a 
deeper hue of olive-grey, when the embryo shows 
through the shell as a dark line, and on the next day 
it hatches. 
On escaping from the shell the larva is a slender 
little creature, with an ochreous-green head, a very 
pale greenish stripe down the back, a blackish-olive 
stripe on the side, a whitish stripe below, and the 
belly dark olive-green. When nine days old it is 
about a quarter of an inch in length, the colouring of 
the stripes rather browner, and within the pale stripe 
of the back appears an extremely fine dark green 
dorsal thread; at this time when disturbed it is an active 
little looper, but otherwise often hangs by a thread 
from a twig motionless; when a fortnight old, the 
dark stripes begin to open into very fine parallel lines. 
At the age of five weeks it is a little more than three- 
elghths of an inch long, of uniform moderate substance, 
with anal legs well developed, ground colour light 
brown, with darker lines and paler edges to them, 
showing much of the characteristics of the mature 
state, viz. blackish subdorsal and lateral marks 
at the hinder parts of some of the segments, and 
thick blackish dashes below the spiracular region ;
