Age” THE ENTOMOLOGIST. 
by Walker. Ratzeburg mentions two or three others, in 
addition to those noticed above. Next to the Chalcidide, 
but lower in the scale of creation than that family, come the 
Proctotrupide, the most slightly-developed of all the Hyme- 
noptera; of this family two or three species are connected 
with oak-apples. Walker names two,—a Ceraphron and an 
TInostemma (Platygasteride); Ratzeburg (‘Die Ichneumonen,’ 
ii. 181) figures a Ceraphron bred from these galls, and which 
he erected into a new genus—Dendrocerus Lichtensteinii ; 
this may be synonymous with the first species of Walker— 
Ceraphronide. 
DIPTERA. 
Cecidomyia ‘sp.?—Of the two species of Cecidomyide, 
bred by Walker, it is very probable that one was the 
C. inflexa, Bremi. Specimens of Tipulide have occurred 
to me as also to Mr. Rothera, in the summer of the first year, 
from these galls; but they belong rather to ore than 
Cecidomyia, I think. 
Anthomyia pluvialis.—This is ha typical species of the 
restricted genus Anthomyia. (Homalomyia) canicu- 
laris, Z., is said to be ey with cabbages, but there 
are many very Closely-allied species. 
LEPIDOPTERA. 
Torlrix viridana, L.—Ratzeburg, in his ‘ Die Ichneu- 
monen, gives sixteen Hymenopterous parasites of this 
species, viz., three Braconide, ten Ichneumonide, and three 
Chalcidide ; of these Hemiteles areator only is included 
amongst Walker’s insects. It is probable that two or three 
pupe of this pretty, but far too common, little moth were 
collected by Walker with the galls, and so came to be bred 
accidentally with one of its parasites. 
Zeiraphera communana.—tThis is the Peedisca (Pecilo- 
chroma) corticana, Hiib., which species is a frequent feeder 
on these galls: but there is another Hiibnerian P. corticana 
amongst the Tortrices, with which it must not be confounded 
—the Antithesia (Penthina) corticana (= picana, Frol.), 
which feeds on the leaf-buds of willow. 
Chetochilus sylvellus.—This species is Cerostoma syl- 
vella, L.
