(,'20 NEW .SPECIES OF HRACONIDiE 



yellowish; antennae 22 jointed, black; parapsidal grooves delicately 

 impressed, lined with pale sericeous hairs, pleura pubescent; metatho- 

 rax smooth ; abdomen ovate, in the female black, excepting the lateral 

 margins of 1st segment, the plate oval, smooth, polished; ovipositor 

 slightly exserted ; in the male the lateral margins of 1st segment and 

 the sutures of the following segments are yellowish, the dorsal portions 

 being brownish instead of black ; legs brown, tarsi dusky. The wings 

 are hyaline, iridescent ; venation as in B. phycidis Riley, the veins pale 

 brown. 



Described from two specimens, one male and one female, reared Sep- 

 tember 18, 1876, from Juncus balticus, and evidently parasitic on some 

 dipterous larva infesting this grass. 

 Bracon juncicola n. sp. 



Male. — Length, 2 mm . Honey-yellow; vertex of head and the surface 

 back of eyes, the raised basal corners of 2d abdominal segment and the 

 apical margins of the following segments more or less brownish; antennae 

 27-jointed, black ; parapsidal grooves delicately impressed, converging 

 behind; metatuorax smooth, polished ; abdomen ovate; the plate of 

 the 1st segment narrowed in front, rounded behind, the lateral margins 

 elevated; legs pale, pubescent. Wings grayish-hyaline, veins pale 

 brown ; the recurrent nervure is almost interstitial with the 1st trans- 

 verse cubital, joining the 1st submarginal cell just in front of it. The 

 female does not differ from the male except in having a short black 

 ovipositor not two-fifths of a millimeter long, and in the posterior tibiae 

 aud tarsi being slightly dusky. 



Described from three specimens, two males, reared September 11, 

 187G, from Juncus balticus, and one female, reared July 10, 1884, from 

 a case bearing Tineid, probably Coleopliora, living on Juncus. 



In addition to the difference in color and number of joints in the 

 antennae there is a slight difference in the venation of anterior wings, 

 which will at once distinguish this species from the other just described 

 from the same plant. 

 Bracon pomifoliellae n. sp. 



Male. — Length, 2 mm . Pale honey-yellow; eyes and ocelli black; 

 abdominal segments from the 3d inclusive, pale brown ; antennae 24- 

 jointed, the two basal joints pale yellow, flagellum brown; parapsidal 

 grooves delicately impressed, and meeting before reaching the scu- 

 tellum ; between their apices and the base of the scutellum are some 

 large confluent punctures; the scutellum is deeply impressed at base; 

 metathorax smooth ; abdomen ovate, the sutures beyond the 3d 

 strongly constricted ; the 1st segment is slightly longer than the 2d, 

 with deep lateral grooves, the plate thus formed being delicately lon- 

 gitudinally aciculated; legs pale; wings hyaline, veins yellowish, the 

 venation as in B.junci, the apical margins ciliated. 



Described from a single specimen, labeled 2Jo. 82 so1 , reared April 

 20, 1871, from Bucculatrix pomifoliella Clem.
