NOTES AND OBSERVATIONS. 1638 
Major Robertson also gave me a bunch of cocoons, which on 
June 7th, 1914, produced thirteen males, from the same host, 
in this case taken jn Co. Fermanach, and from May 16th to 28rd, 
1915, I bred large numbers of both sexes from cocoons sent me 
by L. W. Newman and obtained by him from larve of M. aurinia 
from Bude, Cornwall. Apanteles bignelli, Marsh,* was bred by 
Bignell from this host ; the female is very similar to A. vestalts, 
though the male appears to be widely different. 
Congestus, Nees.t 
This is the Microgaster globatus of Bouché,{ and the M. intrt- 
catus of Haliday.§ It may be distinguished by the hind coxe 
being very distinctly rugulose above. The curious, fluffy, 
yellowish ball in which the gregarious larve envelope their 
cocoons is a well-known object; this ball is usually attached to 
a blade of grass some distance above the ground, the host, no 
doubt, taking up such a position before the parasites emerge 
(fig. 7). The cocoons themselves are thin, white, and placed 
side by side in a cake, arranged almost as regularly as in the 
ease of A. fraternus, the cake being covered by a thin white 
web. The usual number of insects in a brood appears to be 
from sixteen to twenty, though more have been recorded. It has 
usually been bred from larve of Noctuw and is common and 
widely distributed. I have found the cocoons several times in 
the New Forest, and specimens have been sent to me from 
Burnley, Bury St. Edmunds, Crook’s Peak, Deal, Reigate, 
Yeovil, etc.

NOTES AND OBSERVATIONS. 
TORTRIX BELLANA (PENZIANA) IN DurHamM.—In July, 1911, I took 
a specimen of Tortrix bellana at light at Barnard Castle. This, I 
believe, is a new record for Durham County.—J. P. Rosson; Vane 
Road, Barnard Castle. 
AGRIOPIS APRILINA, ETC., IN DurHAM.—In August and early 
September, 1915, I dug up 150 pupe of A. aprilina ; over seventy 
of them at roots of three trees (thirty at one, twenty-six at another, 
and fifteen at a third). The resulting imagines varied from pale 
bluish-green to almost black. Some had the ground colour, a 
yellowish-green, quite distinct from the bluish-green type. Whilst 
digging for A. aprilina at Barnard Castle, 1915, I came across a male 
specimen of Noctua depuncta amongst the dead leaves at the base of
