CONTRIBUTIONS TO OUR KNOWLEDGE OF BRITISH BRACONIDA. : 161 
June 8rd, 1911. In August, 1915, Mr. Waterston, of the British 
Museum, sent me specimens which had emerged from young 
larve of Orgyia antiqua taken in one of the London Parks where 
both host and parasite were numerous. 
Salebrosus, Marsh.* 
Very similar to the preceding species, though probably 
distinct ; the hind femora are entirely black and the belly at the 
base is piceous, in which it differs from solitarius. It seems also 
to be very near melanocelus, Ratz,t and may possibly be the 
same. 
Described by Marshall from two females bred by Bignell 
from larvee of Oporabia dilutata taken in Scotland. 
Cocoon similar in shape and colour to that of solitarius. 
I have always found this species to be a solitary parasite and 
have bred it from Oporabia dilutata, June 20th, 1910; Anticlea 
badiata, June 19th, 1912, and June 26th, 1914; and from 
Cheimatobia brumata, June 21st, 1915. 
Tetricus, Reinh.t

I possess a single insect bred by Major Robertson, Septem- 
ber Ist, 1914, from a larva of Parasemia plantaginis taken near 
Salisbury, which I must refer to this species, though with some 
little doubt. The metathorax is very coarsely rugose, but the 
third abdominal segment is almost smooth. 
Ruficrus, Hal.§ 
Seems to be a rather common gregarious parasite. It is 
easily distinguished by the testaceous fore coxe. I possess 
sixteen, part of a large brood obtained by Tonge from a larva of 
Leucania impura taken at Wye, Kent. Cocoons white, irregularly 
clustered, with considerable loose flocculence. 
Vestalis, Hal.|| 
This species does not appear.to have been recognised since 
Haliday’s time. Reinhard‘ considered the insect described by 
Haliday to be the same as difjiciles, Nees, for which I can see no 
reason ; unfortunately Marshall accepted this synonymy, as in 
other cases brought forward by Reinhard, without question. 
No doubt the types were in Haliday’s own collection, which 
is now in the Dublin Museum. Mr. J. N. Halbert, of that
