Dr. W. H. A s h m e a d ' s classification of the subfamily Ptero- 

 malinae is a step backwards comparatively with that of С G. Т h о m- 

 son. Whole classification of Dr. Ash mead was based on the diffe- 

 rence in the number of the teeth on the right and left mandibles. This 

 character is not always constant even in the limits of one species. 

 Notes I am publishing now were made while I was studying some old 

 collections and had before me the types of genera belonging to 

 this family. These notes are nothing more but material for a future 

 revision of the subfamily, which, I believe, cannot be accomplished by 

 one person. 



The idea of the present work was suggested by Mr. J. C. С r a w- 

 ford, assistant curator of U. S. National Museum. Writer made visits, 

 besides of Washington, D. C, to the principal museums of European 

 continent and had before him the types of' Förster, Ratzeburg 

 and A s h m e a d. The types of Walker and Thomson were studied 

 only those, which are to be found in Wasliington, Vienna and Berlin. 

 The best thanks of the author are dew to the directions of U. S. 

 National Museum, Washington, D. C, k. k. Naturhistorisches Hof- 

 museum in Vienna, Museum für Naturkunde in Berlin and to Prof. Dr. 

 Eckstein from Hauptstation des forstlichen Versuchswesens in Ebers- 

 walde for the permission to study the collections in the question. 



Number of genera described as belonging to this family remained 

 unknown to the author. Of others he has not seen the types. 



Ashmead's family Pteromalidae is quite unnatural one. My 

 opinion is we should partly turn to Thomson's views on the di-
