line, very narrowly edged with grey, forms the dorsal 
stripe ; the subdorsal and spiracular lines are greyish- 
white; and between the subdorsal and spiracular lines 
1s a very fine pale grey line. The segmental divisions 
are yellow, and the spiracles black. Ventral surface 
uniformly bright green, with the segmental divisions 
yellow. 
By the end of May all the larvae had gone down, 
and the imagos from them are now emerging; nine- 
teen males had emerged when the first female put in 
an appearance. (George T. Porritt, March 11th, 
1873; H.M.M., April, 1873, 1X, 272.) . 
Mr. J. G. Ross, of Bathampton, kindly sent me a 
batch of eggs of A. xscularia on the drd of April, 
1877, a portion of which was at once dispatched to 
Mr. C. V. Riley; with me the larvee did not hatch till 
the 25th, while Mr. Riley, in a letter dated the 23rd, 
said the parcel had reached him with the larvee hatched 
and dead. I suppose the temperature in the steamship 
was higher than in my room, and expedited the hatch- | 
ing. My larvee ate oak, and were full-fed during the 
first week in June, but a week later again I beat a few 
from an oak tree, some of which were not full-fed for 
several days after. 
The female moth seems to deposit her eggs in 
patches (there were more than fifty together in one 
patch sent me by Mr. Ross); and they are arranged 
very closely and evenly, touching one another, firmly 
cemented together, and covered over with the long 
fibre-like scales from the maternal anal tuft; the egg 
is oblong, standing upright on end, almost cylindrical, 
but somewhat squared by being squeezed closely 
against the other eggs with which it stands, the upper 
end convex, the lower more flattened ; the shell smooth 
and glossy; the colour olive- brown, browner on the 
top, without much change. 
The larva escapes by eating a round hole through 
the top of the egg, and is at first yellow in colour, the 
internal vessels showing faintly blackish down the
