INSECTS BRED FROM OYNIPS KOLLARI GALLS. 259 
from the galls of C. conglomerata, which are so very closely allied 
to Kollari. Ratzeburg figures the female of S. clavatus (‘ Die 
Ichneumonen,’ pl. vii, fig. 10). 
Chelonus sulcatus, Jur.—One specimen bred by Mr. Billups. 
The Chelonides are mostly parasitic on various Tortrices. This 
species is figured by Jurine, pl. xii., fig. 41. 
Ascogaster rwfipes, Latr.—Mr. Billups also bred one specimen 
of this species. 
Apanteles sp.?—In 1878 Mr. Weston bred three specimens 
of an Apanteles (Hutom. xii. 116); last year Mr. Billups bred 
one. The specific determination must be left. 
Orgilus obscurator, Nees.—This species was described as three 
by the careful Nees, and Ratzeburg figures it (pl. vii., fig. 9) under 
Hartig’s name of Macropalpus (Hubadizon) leptocephalus. Vollen- 
hoven also figures Orgilus in ‘ Pinacographia’ (pl. 29, figs. 8 
and 9). Ratzeburg and several other writers give this as a 
common parasite of Retinia Buoliana ; it is also recorded from a 
Depressaria, a Gelechia, and a Coleophora. Mr. Weston bred one 
male from these galls, where it was probably parasitic on E’phip- 
piphora obscurana. Walker bred the allied Therophilus rufipes 
from galls both of C. Kollari and A. terminalis. 
Aphidius rosarum, Nees.—Mr. Billups bred an Aphidius, 
which I cannot separate from A. rosarum. Cemonus and its 
allies provision their nests with Aphides; this probably would 
account for its occurrence, but Mr. Billups bred no bees. 
Microctonus sp.?—Mr. Billups bred a single female which 
certainly belongs to this genus, but I cannot determine it with any 
certainty from Haliday’s descriptions of Perilitide in the third 
volume of the ‘ Entomological Magazine.’ 
Perilitus sp.?—Mr. Weston bred a male Perilitus ; without the 
other sex it is almost impossible to determine it. The Perilitides, 
of which Vollenhoven’s beautiful plate is just published, are 
mostly lepidopterous parasites. 
Rhizarcha areolaris, Nees.—Myr. Billups bred one specimen of 
this little Dacnusa. 
Dacnusa sp.?—One specimen belonging to this genus also 
bred by Mr. Billups. The Dacnuside are almost exclusively 
parasitic in leaf-mining or gall-making Diptera; their presence 
in these galls must be quite accidental. | 
Cuaucipipm.— All observers bred these in bewildering
