long-antenneed, spotted creature which is the young of this 
Locustid. Fischer well figures the imagos, which are generally 
common in August and September on oak trees, in both sexes, on 
his plate xii., figs. 19 and 20. In the middle of May of last year 
Mr. Bignell bred three of these young larve from galls collected 
the previous autumn ; hence M. variwm must hybernate as an egg. 
NEUROPTERA. 
Elipsocus Westwoodii, M‘Lach.— Two Psoci bred by Mr. 
Bignell (one on 19th May and one on 16th August, 1879) were 
thus named for me by Mr. M‘Lachlan, who adds, “‘ The neuration 
of the specimen on the oblong card is in an abnormal condition 
on the right anterior wing; this and the different setting made it 
appear a separate species.” In 1872 I bred some eight or ten 
Psocide from these and terminalis galls which I sent to Mr. 
Walker, who also had bred several examples. Mr. M‘Lachlan 
suggests that they enter the old pierced galls as larvee to feed on 
the vegetable débris. This is most probable, as Mr. Bignell had 
kept the galls from which the last specimen was bred very nearly 
a twelvemonth. 
Hemerobius subnebulosus, Steph.—In the spring of this year 
Mr. Bignell bred two specimens of this Hemervobius from the old 
galls; they were identified by Mr. M‘Lachlan. This appears to 
be the same species that Mr. Walker bred in April, 1874, from 
galls collected in the autumn of 1873. The Hemerobiide are 
well known Aphis-devourers in the larva state, so itis probable 
that the galls are only used as convenient shelter for their 
cocoons.

THREE NEW ICHNEUMONS. 
By Joun B. Bripeman. 
Tue three species of Ichnewnonide now described apparently 
belong to the same group, and notwithstanding their general 
Pimplid look may fairly be placed between Phygadeuon and 
Hemiteles ; but for their affinities see the article on the gall-bred 
insects by Mr. Fitch. They are all, I believe, undescribed, so a 
specific description is given of each and of the general characters
