HYMENOPTERA. 
417 
ScHENCK has published (Bcrl. ent. Zcits. 1866, pp. 317-369) a 
catalogue of the Aculeate Hymenoptera (including Chrysididce) 
of Nassau, with indications of the species inhabiting other parts 
of Germany. The total number of species observed in Nassau 
is 549 : namely, Apiaria 269, Vesparia 36, Formicaria 42, Fos- 
soria 167, ojid Chrysididce 35. In the classification of the 
Apiaria Schenck adopts the unusual plan of separating the pa- 
rasitic Bees from the rest, forming of them 3 subfamilies — 
Psithyrid< 2 , Melectidce, and Stelidce. Notes on synonymy, varia- 
tion, &c. are appended to many of the species ; and the memoir 
is concluded by a bibliographical notice of the literature of the 
Aculeate Hymenoptera. 
Giraud publishes (Ann. Soc. Ent. Fr. 4® ser. vi. pp. 443-500) 
an admirable memoir on the insects inhabiting bramble-stems 
and their parasites, an amplification of the paper on nearly the 
same subject produced in 1860 by Leon Dufour and Perris, with 
several rectifications of nomenclature. Nearly all the insects re- 
ferred to belong to the present order. The authors just men- 
tioned had obtained in all 27 species of Hymenoptera from the 
bramble ; and of these 12 formed their nests in it, whilst the re- 
mainder were parasitic upon them. Giraud has increased the 
number of nidificating species to 25, and the parasites observed 
by him are 20 in number. The nidificating species are : — 
Antuophila (11) 1. Osmia leucormlana (Kirby) =parvw/a (Duf. &Perr.); 
2. O. atricornis (Duf. & Perr.) j 3. O. tridentata (Duf. & Perr.) ; 4. O. ruhorum
