Hymenopterous Parasites of Colcoptera. 55 
Germany. This may be correct, since in every other case 
the latter writes “ Orchestes” quercus (q. v., ante), but in 
that of Microgaster breviventris (Ichn. d. Forst. ii, 52) it 
becomes “ Curculio” quercus. 
220. Ceuthorrhynchus assimilis, Payk. 
Reinhard bred Diospilus oleraceus, Hal., from the galls of 
this weevil on Sinapis arvensis (as recorded by Kirchner, 
p. 132, and Marshall 11, 259). 
221. Ceuthorrhynchus cyanipennis, Germ. 
Thersilochus moderator, Grav., is said by Brischke (Schr. 
Nat. Ges. Danz. 1880, p. 193) to have “ Aus Larven von 
Ceuthorrhynchus cyanipennis erzogen.” Possibly hyper- 
parasitic—cf. Orchesia micans, ante—through the usual 
enemies of this genus, the species of Drospilus. 
222. Ceuthorrhynchus plewrostigma, Marsh. 
In Ent. Ann. 1874, p. 126, Marshall records Diospilus 
nigricornis, Wesm., as bred from Ceuthorrhynchus sulcicollis, 
Gyll.; this is not referred to in his Bracon. d’EKurop. (ii, 265), 
but, at Jib. cit. i, 320, Sigalphus obscurellus, Nees, is given 
as a parasite of the same beetle “sur le chou.” Diospilus 
oleraceus was bred by Dr. Giraud (Zool.-bot. Ver. V. Sitzb. 
128) from the galls of this weevil. Mr. Horace Donis- 
thorpe bought a turnip in a London shop because it con- 
tained the characteristic cysts of this beetle, from which 
in February 1900 emerged a 2 Sigalphus floricola, Wesm. 
223. Ceuthorrhynchus punctiger, Gyll. 
From this species Giraud tells us (Ann. Soc. Fr. 1877, 
p- 403) that both Bracon maculiger, Wesm., and Porizon 
moderator, Grav., have been bred. As in the case of C. 
cyanipennis, the latter was very probably hyperparasitic. 
224. Ceuthorrhynchus rape, Gyll. 
Diospilus oleraceus, Hal., was bred by Laboulbene from 
the galls produced by this weevil on the roots of Lepidiwm 
draba (Ann. Soc. Fr. 1877, p. 411). e 
225. Baris laticollis, Marsh. 
226. Baris chlorizans, Germ.
