256 THE ENTOMOLOGIST. 
A. geniculatum is new to the British fauna. All the species of 
Anomalon are lepidopterous parasites. 
Campoplex pulchripes, Holmgr.—This is another species new 
to our fauna. Mr. Weston bred one female which either belongs 
to this species (of which the male only is described), or is new. 
Most probably it was parasitic on one of the lepidopterous 
inquilines. 
Campoplex n.s.?—Mr. Billups bred a male Campoplex which 
certainly does not belong to one of our British species. In send- 
ing to Dr. Kriechbaumer, of Munich, it was destroyed, so there 
is no hope now of determining this specimen. We hope for 
more. 
Limneria majalis, Gr.—Mr. Weston bred one male which it 
is at present convenient to call this species. Holmgren separated 
three species from majalis for quite trivial differences, and 
Brischke has just lately split the old species up into several. 
This was no doubt correct, but bred specimens were wanted with 
their biology. We do not yet understand the British specimens 
sufficiently to follow out these minute details. The present 
is therefore Gravenhorst’s majalis, and is, doubtless, a micro- 
lepidopterous parasite. 
L. volubilis, Holmgr.—A new British species, which has been 
referred to by Mr. Bridgman at Entom. xi. 538. Mr. Weston 
bred two males and one female from these galls. 
Cremastus interrwptor, Gr.—Mr. Weston bred one specimen 
of this species; it was most probably parasitic on one of the 
Tortrices. Ihave lately bred the closely allied C. infirmus from 
two-year-old acorns containing Carpocapsa splendana, and 
C. interruptor itself has been commonly bred from R. Buoliana 
(Hartig, Ratzeburg, Bernuth, Wttewaall, &c.). It is also said to 
have been bred by Reissig from Gelechia dodecella, and by Giraud 
from Nothris verbascella, but there are several closely allied 
species. Ratzeburg figures the female in his ‘ Die Ichneumonen,’ 
pL. Wil., fig: 2. 
Mesochorus tetricus, Holmgr.— Mr. Billups bred one specimen 
of this species, which is new to Britain. The genus Mesochorus 
is a very difficult one, and at present very little understood, 
especially in this country. However, we are improving, as 
Dr. Capron (Entom. xii. 89) took thirteen species last year alone 
(there are only twenty-six in Marshall’s Catalogue, and six of
