base, making the extreme basal angles prominent or somewhat tuber- 

 culated, on the bas;il middle a slight elevation, apical margin sinuate 

 and very oblique on each side, behind which the basal angles of the 

 third segment are very prominent or tuberculated; third segment with 

 a deep transverse impressed line, slightly oblique on each side and 

 passing just behind the prominent basal lateral angles; the two follow- 

 ing segments deeply incised at base ; remaining segments suddenly 

 narrowed and slightly pubescent; venter deeply concave; ovipositor 

 nearly as long as the body, rufous, valves black. Length 4 J lines ; 

 expanse of wings 10 lines. 



Collection. — Dr. J. Grundlach. One specimen. 



Readily distinguished from the other species by the abdomen only 

 being rufous. 



Bracon striatulus. n sp. 



Rufous; antenna and legs black: wings dark fuscous; metathorax large and

 long as the body, piceous, valves black. Length 4 lines; expanse of 

 wings 8 lines. 



Collection. — Dr. J. Grundlach. One specimen. 



Readily distinguished by the elongate form and striated abdomen.
