Parasitic Acariis on Crane-Jlies.-^WhWst 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 antennae of several Noctuae, especially Rusina tenebrosa. 

 — Edward F. Bisshopp ; Berners Street, Ipswich, Septem- 

 ber 4^1871. 



Those on the crane-flies are certainly Ocypede rubra (see 

 p. 374) ; those on the antennae of Noctuae T can only suppose 

 to be the same.

 female Emutaria, taken July 26th ; egg hatched, August 3rd ; 

 fed on Polygonum aviculare ; some larvae 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-

 bristles, most on the first 3 segments, are scattered over the

 July 21st, 1870, 1 received a few eggs (or rather larvae, as the 

 eggs had hatched on the way) of Acidalia immutata, from the 

 Rev. J. Hellins, of lilxeter ; and, subsequently, the Rev, E. N. 

 Bloomfield, of Guestling, near Hastings, sent me a further 

 suf)ply of eggs. The young larvae 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-
