INSECTA HYMENOPTERA. 169 



HYMENOPTERA. 



A comprehensive work on this order has been undertaken 

 byDahlbom, under the title ' Hymenoptera Europsea prsecipue 

 Borealia, formis typicis nonnullis specierum generumve 

 exoticorum aut extraiieorum propter nexum systematicum 

 associatis, per Familias, Genera, Species, et Varietates 

 disposita atque descripta/ and the first Part has appeared, 

 (C. A. Koch at Grief swald), embracing a portion of the 

 Linnaean genus Sphex, and the contents of which will there- 

 fore be more particularly referred to below. 



Spinola (Ann. Soc. Ent. Fr. i, p. Ill) has given as a 

 contribution to our knowledge of the Hymenopterous fauna 

 of Spain, ' Notes sur quelques Hymenopteres peu connus, 

 recueillis en Espagne pendant 1'annee 1842, par M. V. 

 Ghiliani, roy. nat./ which is, however, limited to the descrip- 

 tion of the species recognized as new. The author has been 

 unacquainted with "Waltl's 'Reise nach Spanien' (Travels in 

 Spain), in which the Hymenoptera were described by Klug 

 and myself; there are, however, not many species which 

 had been already described there. 



A number of Russian Hymenoptera has been published 

 by Fischer v. Waldhehn. (Guer. Mag. d. Zool. Ins. 

 PI. 122.) 



Although the species here proposed have been already in part long well 

 known, and in part are here insufficiently described, the author is still deserv- 

 ing of thanks for directing the attention of Russian entomologists to this 

 order, who since the time of Pallas, with the honorable exception of Evers- 

 maun, have paid exclusive attention to the Coleoptera. The materials col- 

 lected by Pallas, now ready for publication here, cannot fail, when brought 

 to light, to afford a sure foundation for the future researches of Russian 

 entomologists.
