Parasitic Acarus on Crane-flies—Whilst sugaring in the 
New Forest this year, I observed a crane-fly on the sugar, 
several of whose legs had little red Acari clinging to them, 
the same kind, I should say, that I have observed this year on 
the antenna of several Noctuz, especially Rusina tenebrosa. 
—KEdward F. Bisshopp ; Berners Street, Ipswich, Septem- 
ber 4, 1871. 
Those on the crane-flies are certainly Ocypede rubra (see 
p. 374) ; those on the antenne of Noctuz I can only suppose 
to be the same.

Description of the Larva of Acidalia Emutaria.—A 
female Emutaria, taken July 26th; egg hatched, August 8rd; 
fed on Polygonum aviculare; some larve full grown, 
August 27th. Length, when full fed, about an inch; skin 
rugose, colour of an iron-gray; head iron-gray, with two 
lines of a darker shade on upper side; dorsal line dark iron- 
gray, inclining to black on either side; subdorsal lines 
scarcely darker than ground colour; spiracles black, on each 
side of the dorsal lines on the 8rd segment is a small black 
spot, in size and shape like a spiracle; belly gray; a few 
bristles, most on the first 3 segments, are scattered over the 
body. When disturbed the larva assumes a perfectly straight 
position, with the head and prolegs directed forwards; if 
much irritated, it falls from food-plant and rolls itself up.— _

Description of the Larva of Acidalia immutata.—On 
July 21st, 1870, I received a few eggs (or rather larve, as the 
eggs had hatched on the way) of Acidalia immutata, from the 
Rev. J. Hellins, of Exeter; and, subsequently, the Rev. E. N. 
Bloomfield, of Guestling, near Hastings, sent me a further 
supply of eggs. The young larve fed until the autumn on 
Polygonum aviculare, when they began to hybernate, having 
attained a length of half an inch, and being of average thick- 
ness in proportion. Head a little broader than the 2nd
