No authentic specimens of this species have been studied, and its 

 position in the synoptic table was determined solely from the de- 

 scriptions of Dalman and Mayr. Under this name, however, in the 

 United States National Museum were found four distinct species, 

 three from Europe determined by Walker and Mayr. Two of these 

 are described in this paper as new under the names of melanostomatus 

 and mayri. The third species, also apparently is not ijunctipes 

 (Dalman), and is closely related to liclitensiae Howard from Ceylon. 

 The fourth species under this name was determined by Ashmead, and 

 the single specimen from South Kirtland, Ohio, has been made a 

 paratype of rileyi, new species. It is needless to add that Ashmead's 

 record of punctipes from North America is unreliable.
