ON SOME BEITISH CYNIPID.K.

(Continued from page 8.) 
ii. Thorax coriaceous or glabrous, not villose. Maxillary 
palpi 5, — labial 2-articulate. 
Gen. Andricus, Hartig. 
The species are minute, and differ from Cynips only in a few 
unimportant points. The antennae are frequently longer than the 
body, and more distinctly sub-clavate. Both sexes are known. The 
abdomen of the ? is more compressed than in Cynips ; that of the 
^ is often very small. The disc of the thorax is free from villosity, 
except in A. quadrilineatus, Hart., and A. Rartigii, described below, 
which thus serve to connect the two genera. These insects either form 
galls for themselves, or are bred parasitically in those of Cynips. 
Ajidricits Hartigii, n. sp. 
Antennae 15-jointed, rufo-fuscous. Body ferrugineous ; head black. 
Mesothorax with a broad medial black band, reaching the collar, but 
abbreviated posteriorly, and on either side a narrower stripe, abbreviated 
in front, but reaching the scutellum : the disc glabrous, the sides with 
some traces of villosity ; the discal sutures strongly marked. Scutellum 
sub-rugose, villose, depressed, rufous, margined with black at the base ; 
declivity of the metathorax black, with a rufous dot on each side above. 
Petiole rufous. Abdomen black and polished above, at the base and 
beneath, rufescent ; cariuated from about the middle to the apex; 
slightly villose at the base. Terebra and legs rufous ; the last joint of 
the tarsi fuscous. Wings hyaline ; nervures rufo-fuscous. $ . 
Long. If ; alar. exp. 4 J lin. 
Most like A. quadrilineatus, Hart., but irrecoucileable with his 
short description. It appears to be an Andricus, although the palpi 
are unobserved, and cannot be seen without destruction of the specimen, 
which is in Mr. Walker's collection, and is the only one I have seen. 
Andricus trili7ieatus, Hart. 
Black ; antennae at the base, abdomen, and legs, rufous. Disc of 
the mesothorax transversely rugose, rufous or testaceous, with three 
black bands. Abdomen at the apex, and hinder coxae at the base, 
black. $ . Long, f ; alar. exp. 2^ lin. 
A. trilineatus. Hart., in Germ. Zeits., 2, p. 191. 
It differs from the preceding in being much smaller. The 15-
