Descriptions of one new genus and eight new species of ichnemnon- 

 flies of the family Braconidae are contained in this paper and, in 

 addition, notes on the classification of several previously described 

 but poorly understood braconid genera. Certain synonymical notes 

 are also included. 



For the opportunity of examining some of the genotypes dis- 

 cussed, I am indebted to Dr. H. Bischoff, of the Berlin Zoological 

 Museum; Dr. Erno Csiki, of the Hungarian National Museum, at 

 Budapest; Dr. H. Wachs, of the Pommeranian Museum of Natural 

 History, at Settin, Germany ; Dr. James Waterston, of the British 

 Museum of Natural History; and Prof, E. B. Poulton, of the Hope 

 Museum, at Oxford, England.
