HYMENOPTERA BRED FROM CYNIPS KOLLARI GALLS. oly 
Eurytoma rose, Nees.—Two specimens belonging to this 
difficult genus of Chalcidide were bred. Dr. Mayr has lately 
monographed it (Verh. z-b. Gesell. Wien. xxviii. 297—334), but 
still there is likely to be much confusion, especially to anyone 
following Walker’s determination. Altogether, three very distinct 
species have been bred from Kollart galls. The common 
inhabitant of this and other oak, rose, &c. galls, is the variable 
E. rose, Nees (= Abrotani, Fonsc., = squamea, Wlk.); its size 
and time of appearance are altogether uncertain, but its black 
colour and structure is of course constant. . setigera, another 
oak gall inhabitant, is distinguishable at once by the two long spines 
on the hind tibie, and H. nodularis, Boh. (= rubicola, Gir.) differs 
in many points. This latter species is a common parasite of 
various Crabronide, also of Cryptus ; so that in Kollari galls it is 
possibly hyperparasitic on a lodger. Both Mr. Weston’s speci- 
mens are HZ. rose. 
Syntomaspis caudata, Nees.—Several specimens of this com- 
mon oak-apple parasite were bred. When first I sent this 
Torymid to Mr. Walker as from Kollari galls, he altogether 
doubted it, it then being known only as a common parasite of 
Andricus terminalis ; however, he afterwards bred it from these 
galls himself (Entom. ix. 53). Dr. Mayr only knew it from 
A. terminalis and N. lenticularis galls. 
Callimome regius, Nees.—This very common but brilliant 
cynipideous parasite was of course bred in quantities. Being 
parasitic either on the gall maker or the inquiline, it varies 
greatly in size and somewhat in colour. 
Megastigmus stigmaticans, Faby. (= giganteus, Kollar).—This 
is one of the finest and prettiest of our British Chalcidide, but 
varies considerably. Mr. Weston bred about a dozen examples 
(male and female). It is generally common, but in these galls 
only, in Britain. Mr. F. Walker bred 1103 specimens (682 males 
and 421 females) from one lot of Kollari galls in one year. 
Lamprotatus sp.—Two beautiful specimens of a Lamprotatus 
were bred. This is probably a new species, but a large number 
of captured specimens have been described, which it is almost an 
impossibility to again recognise. Walker described forty-three 
British species in the lst volume of the ‘Entomological Magazine’ 
under the generic name of Miscogaster, and quite as many more 
in ‘Monographia Chalciditum,’‘ Ann. Nat. Hist.,’ ‘Brit. Mus. List,’
