Description of the Larve of Acidalia subsericeata and 
mancuniata.—The following notes on the larve of these 
species or varieties may, perhaps, prove interesting. For the 
opportunity of comparing the two, I am indebted to the 
kindness of the Rev. J. Hellins, of Exeter, who sent 
me the larve in July, 1870. They fed on Polygonum 
aviculare; and, on August 25th, I described them as 
follows. Subsericeata :—Length about three-quarters of an 
inch, tolerably stout posteriorly, but tapering considerably 
from the 9th to the 2nd segment; head small, nearly 
as broad as the 2nd segment, and notched on_ the 
crown; a division in the centre of the face renders the 
cheeks, which are rounded, prominent and distinct; body 
flattened when seen from above, but rounded on the ventral 
surface ; divisions of the 6th, 7th, 8th and 9th segments, very 
conspicuous, the anterior end of each being narrower than 
the posterior; there are a few scattered, but scarcely per- 
ceptible, hairs, most conspicuous on the 2nd segment, when 
they are pointed forwards; skin ribbed transversely and 
rather tough; ground colour composed of several shades of 
brown and ochreous, the 8th and 91h segments being con- 
spicuously of the latter colour, some specimens having a 
faint green tinge; head ochreous, surrounded with dark 
brown; mouth, and central divisions of the face, black; 
from the notch in the head extends the fine pale grayish 
dorsal line, bordered on each side with an equally narrow 
dark line; dorsally, on the anterior part of the 9th segment, 
is a conspicuous rust-coloured mark, shaped somewhat like 
an arrow-head, the apex pointed anteriorly; there are a 
number of confused brown markings along the spiracles, 
which are of a still darker brown; usual segmental dots 
conspicuous, black; the ground of the ventral surface is of a 
beautiful slate-colour, with a series of curiously-shaped dull 
black marks throughout its entire length, which give it a 
very pretty appearance. When at rest the food-plant is 
grasped by the claspers, the body stretched out at full
