of awork that could give me some insight into the species 
I have found in numbers in the course of years. The first 
that gives a collected review of the Chalcididæ is Förster, 
who in his » Hymenopterologische Studien“ part II. Aachen 
1856 p. 87 gives a table of the genera of Trichogram- 
mide; but he hardly mentions the species, and of those 
few he does mention, the description is so poor that it is 
hardly possible to recognize them. In Ashmead’s above 
mentioned work as well as in that of Schmiedeknecht the 
genera found since Forster's time are recorded as far as 
Europe is concerned. Aurivillius gives in the Entom. Tid- 
skrift Stockholm 1897 p. 251—53 a table of genera in- 
cluding his own new genus Oophthora, but neither he 
touches the species. 
Finally in the Transactions of the american Entomolo- 
gical Society Vol. XXXVII 1911 p. 1—42 and p. 43— 83, 
Girault gives information and descriptions of numerous 
new genera and species, but the work hardly touches the 
European species. Claude Morley, Catalogue of the British 
Hymenoptera London 1910 only mentions three genera with 
four species of the Family Chalcidide as found in England. 
On the other hand Max Wolff, Eberswalde, in „Zeit- 
chrift fiir Forst- und Jagdwesen, XLVII Jahrgang. Achtes 
Heft 1915. p. 474-497 and 543—568, gives a review of 
the European Trichogrammine. This work contains really 
something of interest for collectors here in Europe, and 
although the war has evidently placed various obstacles 
in Prof. Wolff's way, it contains so much information, that 
it must be considered the best that has appeared since 
Forster 1856. This work has made it possible for me 
to recognize Forsters genus Centrobia and also made it 
possible to get some idea of what Ophioneurus looks like. 
It is only a great pity that the excellent work of this 
author has been published in such a strange place as the 
periodical mentioned, which is so badly got up, as there 
is no doubt that it will be greatly used in the future.
