114 THE ENTOMOLOGIST. 
Dineura (Nematus) Degeeri, Klug.— This common and variable 
sawfly is spoken of by Mr. P. Cameron as being only a birch 
feeder (Scot. Nat. 11.118). The larve feed gregariously in the 
autumn ; they spin their cocoons in October, but do not become 
pupe till April or May. Mr. Weston bred one male and one 
female from the galls in which the larve doubtless spun up in the 
autumn. 
Emphytus succinctus, Klug. (= togata, Panz.).—The larva of 
this fairly common sawfly is an oak, willow and birch feeder, 
Since the species is known to hybernate as a full-fed larva (Stett. 
Ent. Zeit. ix. 176) it 1s easy to account for its presence in the 
galls, where it found a convenient shelter in which to pupate. 
Mr. Weston assures me the specimens (two males and three 
females) were bred in the galls, as he observed them drying their 
wings. 
Harpiphorus lepidus, Klug. (= ? Fenusa Ianthe, Newm.).—One 
specimen only of this uncommon sawfly was bred. Dours says 
‘La larve vit sous les feuilles mortes des chénes ’’(Catologue, p.17), 
and Mr. Cameron writes me that nothing further is definitively 
known of its life-history. Kaltenbach states that Kirchner has 
observed the larve of Hmphytus melanarius, Klug., EH. togatus, 
Klug., and H. lepidus in the interior (pith) of rose twigs; 
(Pflanzen-feinde, p. 222), but there is probably some confusion as 
to Lepidus. 
Cynips Kollari, Hart.—The principal emergence of this insect 
—the true gall maker—takes place in the autumn, but somewhere 
about 20 per cent are not developed till the succeeding summer ; 
consequently many specimens emerged from Mr. Weston’s galls. 
Synergus Remhardi, Mayr.—A quantity of these cynipideous 
inquilines were bred. Four species are common in these galls, all 
of which winter in them; the specimens I examined were all 
S. Reinhardi, but it is probable that S. melanopus also occurred. 
2 Cryptus sp.—Six examples (four males and two females) of 
a remarkable and interesting Ichneumon were bred. Although 
a particularly well-marked species, it is difficult of determination, 
even generically. Mr. J. B. Bridgman, Dr. Capron, Dr. Kriech- 
baumer, and the late Mr. F. Smith all saw them, but without a 
satisfactory result as to their nomenclature. 
Hemiteles areator, Panz.—Hight or nine females of this pretty 
but common little Ichneumon were bred. It has been recorded
