DESCRIPTIONS OF NEW HYMENOPTERA. 2. 



By J. C. Crawford, 



Assistant Curator, Division of Insects, U. S. National Museum. 



In this paper 15 new species are described. Many of these were 

 received from the correspondents of the Bureau of Entomology, U. S. 

 Department of Agriculture, for identification, and are of economic 

 importance so that the early publication of their descriptions is nec- 

 essary in order that the names may be used in economic bulletins. 



The comparative measurements used in the description of the new 

 species were made with an eye-piece micrometer used in the number 

 two eye-piece in the binocular microscope. 



Superfamily PROCTOTRYPOIDEA. 

 Family SCELIONID.E.
