lism, with two new species, H. seminiger, from Brazil , and H. Behni, distin-guished by smooth metanotum; iu the Fabrician Collection placed withCrabro fossorius; ( Gorytes, Nysson.) Stizus should remain in its naturalplace, in the following family:

Bembecides.- —Dahlbom (Hym. Europ .) has formed a distinct genus,Sphecius, from Sphex speciosa, Drury, but in what respect this differs fromStizus is not stated.

ScoLiETiE.—Shuokard (Trans. Ent. Soc. Lond. iii, p. 222) has correctedthe description of Scolia fulva, in ‘ Griff. Anim. Kingd.,’ and at the same timeremarked that it is not, as there stated, from South America , but from NewHolland.

Fischer v. W. (1. e.) has characterized three Russian Scolietae, of which,in Scolia rufiventris, may be recognized Sc. rubra, Jur.; Myzinespinosais indu-bitably a true Myzine, but the species is not to be determined; Myzinearcuata, lastly, is a male Scolia, and most probably that of Scolia 5-cincta,which is distributed far into Siberia .

Spinola (1. c.) has described two new species of Myzine, which are veryclosely connected with M. higmorrhoidnlis, Guer., from the Cape; having incommon with it the posterior abdominal segment of a red colour: M. his-panica, from Andalusia , and M. Ghilianii, from Sicily .

Mutillaim. —Spinola (1. c.) has enriched Mutilla with several South European species, M. %-maculata, Ghilianii, fasciaticollis, from Spain ;M. triareolata, from Sicily , and M. Rondani from Parma. But the first,M. %-maculata, has been already described by Klug as M. 9 -quttata, Kl., inWaltl’s Travels.

A memoir on the New Holland species of Mutilla has been furnished byWestwood (Arcan. Ent. p. 17, pi. 53, 54), with numerous figures. Thereare altogether eleven species, of which four are given in Fabricius; the resthave been established by the author. M. dorsigera, Westw., I consider iden-tical with M. Australasia, F. The Berlin Collection possesses at presenteleven New Holland species of this genus, of which only three occur amongthose noticed by Westwood.

Thynnidje. —Id. (ib.) has given a figure of Fsamatha chalybea, Shuck.,and Diamma bicolor, Westw., from Van Diemen’s Land. Both, however,are probably connected as male and female.

VesparijE .—Eumenes venusta, a Wasp has been described by Fischer v. W.(1. c.), as a new species, both sexes of which are figured, but which was pre-viously represented by Christius, as Sphex tripunctata.

White (Ann. Nat. Hist, xii, p. 268) has added to his former memoir onthe Honey-wasp (Ann. vii, p. 315), some remarks of Mr. Hawkins, by whomthe nest was sent.

Milne Edwards (Ann. de la Soc. Ent. de Fr. 2 ser. I, p. 34) has de-
