ACIDALIA MARGINEPUNCTATA. 
Pl. CXVIII, fig. 6. 
One young larva of A. straminata |marginepunc- 
tata of Stainton’s Manual], the survivor of two larve 
reared from eggs, reached me October Ist, 1872, 
from Mr. J. R. Wellman, feeding on knoterass. 
On the 4th he sent me three more, being all his 
stock, and the following particulars. The parent 
moth was captured in the New Forest in July, 1872, 
by a friend of Mr. Wellman’s, who forwarded hi mthe 
egos laid in a cluster of about ten or eleven. When 
Mr. Wellman received them they were of a pink 
colour, and about the size of eggs of A. rusticata; and 
before hatching they changed to a dark slaty-brown. 
By the 5th of October the larve had attaimed the 
length of three-eighths of an inch. They were mode- 
rately slender, very slightly tapering forwards from 
the ninth segment, the head a trifle the smallest and 
indented on the top of the crown, full and rounded at 
the sides, the last five segments of about uniform 
bulk; the upper and under surfaces are convex, with 
a spiracular inflated ridge along the sides tending to 
give rather a flattened look to the back. The seg- 
ments are decidedly rugose, with about twelve deep - 
subdividing wrinkles on each. ‘The bristles are very 
short and stumpy, rather numerous about the head 
and the anal extremity. 
The ground colour of the back is a pale grey, chiefly 
seen in an imperfectly elliptical, somewhat diamond 
shape on the fifth to the ninth segments inclusive ; 
this 1s defined by blackish; a faint whitish-grey 
dorsal line appears only just at each end of this mark, 
which is strongly edged with black; on either side the 
orey becomes suffused with darker ; the subdorsal lines 
are black, with a fine whitish-grey line on each side
