648 NEW SPECIES OF BRACONID.E. 



or less, and the two basal segments of abdomen, pale yellowish; the 

 tip of the abdomen is black or piceo-black. The antenna' are broken 

 off at tips, but the joints of the flagellum remaining are cylindrical, the 

 1st the longest, the 2d and following about twice as long as wide. 



Thorax ovoid, smooth, polished, without grooves; the mesapleura 

 with a crenulate furrow across the disk; metathorax delicately areolated. 

 Wings, hyaline, iridescent ] veins, brown; the venation is similar to 

 the preceding species, only the 4st branch of the radius is very short, 

 about one-fifth the length of the oblique 1st transverse cubital nervure; 

 the 2d submarginal cell is, therefore, proportionately widened at base, 

 narrowed at apex. 



Habitat. — Ames, Iowa. 



Described from one specimen received from Prof. H. Osborn, labeled 

 "Bred from a dipterous larva in stem of cabbage." No date is given. 



PH.ENOCARPA Forster. 



Phaeiiocarpa americana n. sp. 



Female. — Length, 4-s"'" 1 ; ovipositor, If nim . Black, polished ; antenna', 

 except dusky toward tips, mandibles, except teeth, and legs, iiavo- 

 testaceous. The face and cheeks arc covered with a whitish pubes- 

 cence; the antennae %re broken, but there are 17 joints remaining; the 2d 

 flagellar joint is longer than the 1st, the following gradually becoming 

 shorter and shorter; the mesothoracic grooves are distinct, crenulate ; 

 the middle lobe, thus formed, has a distinct, short, longitudinal grooved 

 line posteriorly, connected at apex with two oblique grooves that 

 extend iuto the parapsidal grooves ; the scutellum has a deep fovea at 

 base which is separated into two parts by a delicate keel ; metathorax 

 rugose, with a very short medial keel back of the post-scu tell urn ; the 

 abdomen is as long as the head and thorax together, depressed above, 

 boat shaped beneath; the 1st segment is aciculated, with deep lateral 

 grooves and two delicate, longitudinal keels on the disk, beneath piceous; 

 the following segments are smooth, polished, the sutures being with 

 difficulty made out. Wings, hyaline; stigma and veins, brown ; the 

 submedian cell is slightly longer than the median; the 2d discoidal 

 cell long and narrow, a complete parallelogram ; the recurrent nervure 

 is interstitial with the 1st transverse cubital nervure, the latter oblique; 

 the 2d transverse cubital nervure is about one-third shorter than the 

 1st transverse cubital nervure, and surrounded by a brownish spot ; 

 the 2d submarginal cell is therefore narrowed at apex. 



Habitat. — Washington, D. C. 



Described from one specimen. 



ISCHNOCARPA Forster. 



Ischnocarpa atricomis n. sp. 



Male and female. — Length, 2? to 2§ mm j ovipositor, | mm . Black, pol- 

 ished; the 2d and apical abdominal segments, piceous; palpi and legs
