9. Die faniilien der Blatticespen und Holzwespen Deutsch- 

 lands. {The Families of Leaf Wasps {Tenthredines) and 

 Wood Wasps {Sirices) of Germany, hy Dr. Theodor Hartig. 

 Sro. Berlin, 1837.) — This, as far as we have yet been able to 

 examine it, we consider to be a very useful book, and possesses 

 the additional utility of specially attending to the early stages 

 of the insects of which it treats. Amongst the Tenthredinidw, 

 the author has introduced very many new genera; and the 

 value of the work is very much increased by most of the genera 

 being treated monographically, which implies greater and more 

 serviceable details than the ordinary mode of description con- 

 veys, and he is only brief where Klug has previously described, 

 who can consequently be readily referred to. Considerable 

 attention is paid also to the synonymy, which we are glad to 

 see diligently and honestly cultivated, as it is the only mode 

 of awarding merit to the right individual. We may, perhaps, 

 give the system of arrangement here introduced, in a subsequent 

 number. The work is accompanied with eight plates, giving 

 the larvae and dissections of the genera.
