162 OPORABIA DILUTATA. 
the equidistant lines and the spiracular whitish ridge 
which runs through the lower part of the blotch; this 
ridge is rather more distant from the lower line than 
the two lines are from each other, and continues to 
the beginning of the anal flap. The spiracles are 
orange, finely outlined with dark crimson; the situa- 
tion of each is within the blotch, and relieved by a 
small halo of green just above the whitish ridge, which 
from inflation is more noticeable; the colour of the 
beliy is of a blue and paler green, blending to white in 
the middle, whereby the three ventral white lines show 
but indistinctly. ‘lhe deep rose-pink or crimson dorsal 
stripe 1s so interrupted that it shows only about mid- 
way on each segment,and is intersected either with one 
or with two short transverse stripes; if with two the 
shorter 1s in front; very often the area they occupy 
is faintly tinged with light pinkish ; in some examples 
the dark pink shows only as a smooth interrupted 
dorsal stripe, more or less faint or nearly obsolete, 
and occasionaily mere spots, but when present it is 
always strongest on the penultimate segment; in 
others the pale yellowish or whitish fine lines are so 
faint as to be scarcely distinguished, as are sometimes 
also the tubercular dots, when the larva appears to be 
of a plain velvety green above and a whitish-green 
beneath, though still a trace of the whitish or yel- 
lowish spiracular ridge remains, especially on the 
posterior segments (two magnified segments with 
fig. 1, 1881, show all needful particulars). 
The moths from the foregoing larve emerged on 
October 11th, November 4th, 10th, and 15th, 1881, 
all ¢ with the exception of one ¢. ‘They were of a 
very light grey type, the ¢ the lightest. I sent a 
batch of eggs to Mr. Hellins. 
On turning out the pot the cocoons were found to 
be about half an inch long, of a blunt oval general 
figure, composed externally of grains of earth, and 
smoothly lined with dirty grey silk inside. 
The pupa is of a dumpy shape, being stout in pro-
