Relates chiefly to the " Phileremides " of Lepelletier. 
Snellen van Vollenhoven, S. C. Schetsen ten Gebruike 
bij de Studie der Hymenoptera. I. Iclineumoniden_,

Thomson, C. G. Hymenoptera Scandinaviae. Lund : 8vo, i. 
1871, pp. 1-342; ii. 1872, pp. 285, 1 pi. 
Vol. i. (reviewed in Ent. M. M. viii. p. 189) comprises Tenthredo and Sirex, 
Linn., and commences a proposed monographic revision of the Swedish 
species of Hymeyioptera. Vol. ii. comprises Apis, Linn. As usual, the au- 
thor is original in his treatment : his habit of investigating all portions of 
the structure of any insect to which his attention is directed, and of not con- 
fining himself to any one set of organs, causing him frequently to arrive at 
conclusions at variance with those of former writers. In discussing the 
Tenthredinid<B, however, he omits to notice the larval stage, in spite of Dahl- 
bom's valuable observations upon it. 
Kbaplin, Tagebl. xlv. Vers. Natur. p. 140, notes the homology between 
the last abdominal segments of the S and $ . 
Japan (Hiogo). In a collection received from this country, all the genera 
(except one of Formicidm) were European, and some of the species appeared 
to he identical with European : F. Smith, P. E. Soc. 1872, p. xx. But the 
collective faunas of the two regions are totally distinct : H. W. Bates, ibid. 
p. xlvii. 
Apid^. 
Thomson, Hym. Scand. ii., adopting as primary the sections Sociales and 
Solitaries, comprises in the former the tribes Apina and Bomhina, and in the 
latter the equivalent tribes of Megillina, Andrenina, Halictina, Nomadina, and 
Melectina. For all of these he points out fresh characters, derived from 
varied structural peculiarities. 
F. RuDow, S. E. Z. xxxiii. pp. 414-429, recapitulates the species of the 
Lower-Harz district, with brief notices of habits, times of appearance, &c. 
Andrenides. 
Doims, R. Z. (2) xxiii. pp. 293, 349, 396, 419, et seqq., under the title of 
" Ilymenopteres nouveaux du bassin mediterraneen," describes various new 
species of this group (many by L. Dufour & Sichel, unpublished before). 
Hyl(Bus. MoRAWiTZ, Verb. z.-b. Wien, xxii. p. 374 et seq., reviews 
Forster's monograph, adding to it 9 European species already recorded. H.
