REPORT ON ZOOLOGY, MDCCCXLIl : 
accompanied by many valuable remarks on their appearance. Leunis 
has made known a list of the Tenthredinidce, found in Hildesheim and 
the adjoining Harz (Ent. Zeit. p. 42). 
P. 'Huber * (M4m. d. 1. Soc. d. Phys. et d’Hist. Nat. de Geneve, ix. 
pt. 2) has described the natural history of the larva of a Lyda, which is 
found rarely upon hazel bushes, and forms a house for itself by rolling 
up strips of the leaves. It has not arrived at its change, therefore the 
species remains undetermined. (This treatise has also been noticed in 
the Ann. Nat. Hist. xi. p. 241, and Ann. des Sc. Nat. 1843.) West- 
wood (Ann. Nat. Hist. xi. p. 376) remarks, that this larva may belong to 
the Lyda inanita, of which he has given a short account in his “ In- 
troduction” (v. 2, p. 107, f. 71, 11). This determination appears to me 
still doubtful, as Westwood observed the larva upon roses; and I hold it 
probable, that a similar habit may be common to the leaf-eating larvae 
of several Lydoe. 
Harris has made some interesting remarks on the natural history of 
several North American Tenthredinidce and Sirices, in the “ Ins. of 
Massachusetts.” Cimhex ulmi, Peck (male Americana, Leach), lives 
on the common and American elm. A Lophyrus, L. ahietis, Harris, 
lives on pines. It is very like, or identical, especially the caterpillar, 
with L. rufus, Kl. Selandria vitis lives on the vine ; the slimy cater- 
pillar of the S. rosce, on the rose ; S. cerasi (Teyithr. c., Lin., T. cetkiops, 
F.) also exists in North America upon fruit trees, especially the pear. 
Tremex coliimha lives in pear trees, and elms, &c. The larva is attack- 
ed by Pimpla atrata. Urocerus albicornis, F., is found in pine wood; 
also the new species, U. nitidus, ditferent from U. juvencus, by its 
brighter colour and shorter antennae ; and U. abdominalis, probably the 
male of the preceding, in the white pine. There are two new species of 
Xiphydria, X. albicornis and mellipes ; and of Oryssus, besides the 
O. terminalis, Newm., and Sayi, Westw., there is a third, 0. ajinis, 
Harris, which possibly may be only the male of the latter. 
IcHNEUMONiD^. — Drewscn has proved, by observing their pairing, 
that Ichneumon culpator, Schr., is the true female to I. sputator, also 
that Pimpla jlavipes is the true male to P. stercorator, while Graven- 
horst has described as such the male of P. graminellce (Kroyer Natur- 
hist. Tidsskr. iv. p. 103). The reporter (Arch. 1842, 1 Bd. p. 255) has 
described several species from Van Diemen’s Land ; Ichneumon peti- 
* By way of appendix, I may mention here another treatise by the same 
author (ibid,), in which he has given some pretty observations on the Cocci- 
nella glohosa, 111., but which contains nothing essentially new, as it is already 
known from other sources, that the species named, as well as some other Coc- 
cinellce, are plant eaters. The generic name of Suhcoccimlla is already the 
third proposed for the above species, which, contrary to all rule, has been 
enrolled among Saponarice (S. vor Bericht, p. 258).
