NOTES, CAPTURES, ETC 159 



such a number of figures will procure me so much knowledge 

 of the relationship of the different genera that 1 may be 

 induced at the end of this work to give a general systematical 

 review of the families examined." This is from the Intro- 

 duction; and if the tables of species and tables of parasitism, 

 which are promised, be given it may be made a complete 

 work. Much of Ratzeburg's information needs revision. Too 

 much cannot be said in praise of the extreme excellence and 

 beauty of the plates : they are so absolutely correct both in 

 colour, delineation of the structural details and general 

 excellence of production, that it must be almost impossible 

 to fail to recognise the species at once. They are all drawn 

 by Snellen van Vollenhoven himself, and most carefully 

 engraved by A. J. Wendel. With these figures at hand it 

 can be by no means difficult to work out to a fuller under- 

 standing of the genera the descriptive works of Gravenhorst, 

 Forster, and Tliomson, or the scattered papers of our own 

 Haliday and Walker in the smaller species. ' Pinacographia' 

 treats of the Ichneumonidce, in the Linnean sense, and so 

 includes most of the parasitic Hymenoptera, viz.^ the 

 IchneumoiiidcB, the Braconidce, the Proctotrupidce {Oxyura), 

 and the Chalcidida. A synopsis of the various genera has 

 already been translated into English ;* and it is to be hoped 

 the appearance of the work now under notice, if carried to 

 completion, will materially help to the filling in of this large 

 framework. Although printed in English I believe there are 

 something less than half a score copies of this beautiful work 

 find their way into Britain ; this I can but think is because it 

 is not better known. For an acquantance with Ichneumons 

 generally there is certainly nothing to equal it.
