THE ENTOMOLOGIST. 39 
(1) Pleromalus Cordairti, Ratz. = ¢ Neesii, Ratz.—Bred 
by Herren Erichson and ‘Tischbein from the gall of this species, 
and of A. curvator. 
(2) Pleromalus Dufourti, Ratz.—Bred by Herr Reissig 
from second-year galls of A. terminalis and Cecidomyia 
(Hormomyia), Lagi. 
(3) ? Pleromalus gallicus, Ratz.—Bred by Herr No6rd- 
linger from ‘* Gallapfeln.” 
(4) Pleromalus leucopezus, Ratz.—Terminalis-bred speci- 
mens, received by Ratzeburg from Herren Nérdlinger, Tisch- 
bein, and Reissig (commonly). 
(5) Pleromalus stenonotus, Ratz.—Ratzeburg bred both 
sexes of this species from this gall himself, and received a 
female from Ziegler, bred from Tinea cognatella—H ypono- 
meuta cognatella, Hiid. 
(6) Pteromalus meconolus, Ratz.—A single female bred by 
Ratzeburg ; and fifteen males and five females bred by Herr 
Tischbein from these galls. Herr Nérdlinger also bred it 
from them at the end of May (first or second year not 
stated). 
(7) ? Platymesopus Westwoodii, Ratz.—Bred by Herr 
Saxesen in July, 1837, from an oak Cynips; the species was 
not specified, but it was probably A. terminalis. 
(8) Platymesopus Erichsonii, Ratz.—Bred by Herr Erich- 
son, from the gall of this species (A. terminalis). 
Elachistide. 
Eulophus gallarum, Lin.—This is one of the most frequent 
and abundant inhabitants of oak-apples, and it is also com- 
mon in many other galls, occurring in both the first and 
second years. Ratzeburg gives five species of Eulophus 
and eight species of Entedon as parasitic on Orchestes 
Quercus alone. Ratzeburg’s Entedon scianeurus is probably 
this species, which is not a true Eulophus, but an Olynx. 
Tetrastichide. 
Tetrastichus Diaphantes = Cirrospilus Diaphantus, Wk. 
_ —This insect belongs to a very extensive family, Walker 
alone having described about one hundred and eighty 
species of Tetrastichus. 
I believe the above includes all the Chalcidide mentioned
