scribed the nest of Epiipone tatwa {Pol. mm-io, F.) It is not thicker thanpaper, but firm, constructed around the branch of a tree, and resembles in itsform, and in the annulation of its surface, the mail of the Armadillo {Tatu),whence its name.

Spinola has published a short memoir, ‘ Osservazioni sopra caratteri na-turali di tre famiglie d’Insetti Imenotteri cioe le Yesparie, le Masari et leCriside,’ Genova, 1843, which is intended principally to oppose Lepelletier’sextraordinary division, by which the social Wasps are widely separated fromthe solitary. The author directs attention particularly to this circum-stance, that in the Vespse, besides the longitudinally plicated wings, the powerof directing the abdomen upwards is provided for by the form of the meta-thorax, together with which the Masarid® also combine the power of doublingit in, by which the Chrysidid® are distinguished, which, however, do notpossess the former power.

Apiaries. —Several remarks maybe made with respect to the Spanish Beesdescribed by Spinola (1. c.) Andrena lamiginosa is my An. pruinosa (inWaltl’s Travels.)— Sphecodes collaris, Spin., new; (occasion is here taken todescribe two other new species, Sph. rubripes, from Bombay , and Sph cribosus,from South Africa .)— Basypoda bcetica , Spin., is, according to the specimenscommunicated by Rossi, his true D. discincta.—Comptopmim is the namegiven by the author to a new genus which is intended to embrace Prosopisfrontalis, F. {Panurgus rmsutus, Spin.), and to which a new Spanish species,C. interniptmt, is added; which is, however, probably the female of myPanurg . venustus. (Waltl’s Travels.)— Ammobates mutieus, Spin., scarcely dif-fers from A. rufiventris, Latr.;—to which the author objects that in Latreille’sspecies the tibiae and tarsi are both red, whilst in his, the tarsi onlyare so; in the specimen in the Berlin Collection the tibiae are half red,whence it follows that this difference is of no great importance.— Osmiabcetica, Spin., corresponds in many particulars with my 0. rutila (Waltl’sTravels), and is probably only a variety. 0. rutila has a dark red abdo-men, and the legs are entirely red.— Megachile Qhilianii, Spin., is un-known to me. — Xylocopa sinuatifrons, Spin., is X . cantabrica, Lepell.;and X . hellenica, Spin. (1. c.), from Greece , is identical with X . olivieri,Lepell.

Fischer, v. W. (1. c.), has instituted: Melecta fasciculata, and 14 -punctata,both from the Upper Ural; Bombus melinoides, from Irkutsk , differing fromB. sibiricus, F., only in the absence of the red band on the thorax; Apisdaurica, from the same part, and from South Russia, is scarcely more thana local variety of A. mellifica.

F. Smith (Trans. Ent. Soc. iii, p. 293) has observed Nomada Schaefferella( ? of IF. connexa, Kirby), as a parasite of Eucera longicornis. The Beeswere on the wing together in June, and when he dug up the nests in March,
