ON THE GENERA OF THE EUCHARID^E. 

 By WILLIAM H. ASHMEAD. 



In my paper entitled " Notes on the Eucharids found in the 

 United States," read October, 1892, I wrote: " Since becoming 

 better acquainted with that great complex of the Hymenoptera at 

 present known to us under the family name Chalcidida, I have 

 gradually come to the conclusion that instead of a single family 

 to deal with we have several distinct families. Indeed, in many 

 cases, these families are even more distinct and sharply defined 

 than many others of the so-called families in this order, and until 

 these are properly separated and defined, I believe but little real 

 progress can be made in our systematic knowledge of the Chalci- 

 doidea." 



Since this was written, I have diligently and laboriously prose 

 cuted my studies on these insects, and have now in MSS. a new 

 classification of them, which I hope to publish this winter, in 

 which I have recogni/ed fourteen distinct families. 



Inasmuch, therefore, as I have entitled this paper " On the 

 Genera of the Eucharidee," I desire briefly to put on record the 

 names of these families and the new arrangement proposed in this 

 work. 



The families recognized and their arrangement are as follows:
