AN .UIERICAN SPECIES OF THE HYMENOPTEROUS GENUS 

 WESMAELIA OF FOERSTER. 



By P. R. Myers, 

 Of the Bureau of Entomology, United States Department of Agriculture. 



The description of this species adds an American representative 

 to this rare and Httle known genus which has hitherto been unrepre- 

 sented by an American species. The species is apparently a very 

 close relative of Wesmaelia cremasta Marshall.
