HYMENOPTERA BRED FROM CYNIPS KOLLARI GALLS. 
By Epwarp A. Firca. 
We know of several isolated instances of illegitimate inhabitancy 
of galls by various orders of insects, which enter them at various 
stages of their existence, either to undergo their transformations 
or on account of the facilities offered for a secure and snug 
retreat from the snows and frosts of winter. This is not surprising; 
the young and succulent galls cannot be considered to offer an 
unsuitable pabulum for many phytophagous larve; the mature 
growth in many cases offers a substantial home to certain species, 
and when empty and in the decrepit state certain galls offer 
throughout the winter a most convenient hybernaculum to all 
insects, size only being the consideration ; large numbers of small 
spiders and mites also avail themselves of these advantages. The 
large, round, woody, marble galls of the oak, commonly known as 
the Devonshire gall, is abundant everywhere. Last winter Mr. 
Walter P. Weston collected a quantity of these galls for the purpose 
of rearing H’phippiphora obscurana ; he was not only successful in 
this, but secured from them a most interesting general collection. 
This included six species of Lepidoptera (Entom. xi. 239) ; seven 
Coleoptera, and thirty Hymenoptera: our note refers especially to 
the latter. The six Lepidoptera were all Tortrices, and have been 
sufficiently referred to. The Coleoptera were Olibrus eneus, Fab. 
(common) ; Dasytes eratus, Steph. (abundant) ; Anaspis maculata, 
Fourcr. (five or six); Orchestes quercus, L. (a few); Celiodes 
quercus, Fab. (two specimens); Coccinella bipunctata, L., and 
C. variabilis, Ill. (a few specimens of each). ‘These were probably 
all hybernating imagos, and call for no special remarks. Not so 
the Hymenoptera, which were as follows : —
