36 THE ENTOMOLOGIST. 
immutator, Nees, has been bred from these galls by Dr. 
Reinhard ; it was probably parasitic on a Curculio. 
Microgaster sp.?—Both sexes of Microgaster (Apanteles) 
breviventris, Rizb., have been bred from the gall of this 
species, in which they were probably parasitic on Orchestes 
Quercus. 
Aphidius sp.?—This undetermined species of Aphidius 
was probably parasitic on an Aphis. 
In addition to the above list of Ichneumonide, Ratzeburg 
received three other species from his numerous corre- 
spondents, as follows :— 
Cryptus hortulanus, Grv.(Ichneumonidez).—“ Herr Reissig 
bred one femalé from Cynips terminalis galls at the end of 
May of the second year; with it the very common Hemiteles 
punctatus.” (Ichn. d. Forst. ii. 124.) 
Microtypus Wesmaelii, Rizb. (Braconide). Ratzeburg 
himself bred a solitary individual from an A. terminalis gall, 
which he erected into a new genus, separated from Micro- 
gaster; it was bred, with hundreds of Torymide, at the end 
of June (1847). 
Microdus rufipes, Wesm. = Therophilus rufipes, Nees. 
(Braconide).—Several specimens bred by Herr Bouché from 
these galls, in which it was parasitic on Hedya ocellana. 
CHALCIDID&. 
Eurytomide.

Decatoma immaculata.—Ratzeburg records Eurytoma ~ — 
signata, Nees, as very commonly bred from this gall; he 
also gives it as parasitic in several other galls and on a 
Lithocolletis. It is undoubtedly a compound species, and 
from his description certainly a Decatoma; so the A. termi- 
nalis-bred specimens were probably the same species as 
Walker’s D. immaculata. 
Torymide. 
Callimome nigricornis, Fab.—This is Syntomaspis caudata, 
Nees. Ratzeburg gives Torymus admirabilis, Férst. (= cri- 
nicaudis, Ratz.) as bred commonly from A. terminalis galls; 
they are both synonyms of this species, which occurs very 
abundantly in the spring of the second year. It has also
