262 HYMENOPTERA. 



width ; posterior wings with the usual paired rows of discal ciliation 

 around the edges of the blade and centrally a short midlongittidinal 

 line running from the apex and containing about from 8 to 10 cilia. 

 Proximal tarsal joints not long but longer than any of the other four, 

 moderately long. 



Antennas slender, the funicle subclavate ; scape together with its 

 rather long bulb equal in length to the combined lengths of the pedicel 

 and first four funicle joints, slender, slightly thickened in the middle. 

 Pedicel usual, obconic, distinctly longer than either of the first four 

 proximal funicle joints, but slightly shorter than any two of them 

 combined, wider than the scape or any part of the funicle ; first four 

 funicle joints subequal in length, slightly longer than wide, small, 

 slender, but 3 and 4 of funicle subequal in size, wider than 1 and 2 ; 

 funicle 5 is abruptly longer, twice the length of 3 or 4, cylindrical, 

 wider, about equal to pedicel in length ; 6 is shorter and somehat nar- 

 rower than 5, but a third longer and wider than 3 or 4 ; 7 of the funicle 

 larger, somewhat longer and wider than S, the longest funicle joint ; 

 8 is slightly broader than 7 but shorter than 5 or 7, a fourth longer 

 than 6. The club is slender, long-ovate, as long as the three preced- 

 ing joints combined, shorter than the scape. It bears a few longitu- 

 dinal grooves. 



From 2 specimens, f-inch objective, 1-inch obtic, Bansch 

 and Lomb. 



Male. — The same but lighter in color, the base of the abdomen above, 

 intermediate femora and fore part of thorax beneath, cream yellow; 

 flagellar joints strongly striated longitudinally, concolorous with body. 



From 2 specimens, the same magnification. 



Described at first from two female specimens found tag- 

 mounted in the U. S. National Museum collections labelled 

 simply "Ind". They have been remounted in balsam. This 

 species is similar to English specimens in my possession 

 labelled Gonatocerus flavus, but for the present I consider 

 them distinct. 



Habitat. — United States : Indiana ; Illinois (Urbana, Mat- 

 toon, Centralia).
