ACIDALIA MANCUNIATA. 117 
that marking, whilst those (or some of them) I had 
lately were very conspicuously blotched.” Subse- 
quently, when in Huddersfield, Mr. Barrett saw my 
A. subsericeata larvee, and found they varied very much 
from those he had reared; indeed, my A. mancunata 
were more like his A. swbsericeata than were my larvee 
of that species. I offer no opinion as to the distinct- 
ness of the two species. (George T’. Porritt, November 
Ath, 1871; Hnt., December, 1871, V, 453.) 
At the time that Mr. Hellins sent me two larve as 
variations of A. subsericeata, 1 remember making 
known to him that they were not the least like those 
of that species sent to me in October, 1862, by 
Mr. Crewe, nor yet like others [ had in April, 1868 ; 
for both Mr. Crewe’s examples and the last named, 
although they varied slightly, were all constant to one 
particular, viz. a pale yellowish or whitish mark on 
each side of the ninth segment. 
It will be seen by the subjoined description that, 
from A. subsericeata, A. mancuniata is more distinct in 
the larval than in the perfect state, even the character 
ofits markings being entirely different. 
Description.—Larva about three-quarters of an inch 
long, tapering gradually towards the head, which is 
erey-brown, with a dark brown line on each lobe. 
Ground colour of the body pale reddish-grey ; dorsal 
line scarcely paler, very thin, and enclosed by a broad 
brown line on either side, which gradually widens 
down to four-fifths of the segments, and then contracts 
towards the segmental divisions, and at the widest 
portions on each side is a rather large spot or blotck 
of blackish-brown. 
The subdorsal lines are of grey-brown, very thin 
and double, with a blackish-brown oblong blotch on 
them, about the same distance from the end of each 
seoment as those on the dorsal region. 
The last four segments appear paler than the others, 
as the dorsal line on them is enclosed only by thin 
brown lines, and the subdorsal lnes on them also
