dusky hyaline, iridescent, veins brown, stigma yellowish ; venation 

 as in B. phyeidis, but the 2d subuiarginal cell is much lengthened 

 along its basal margin being twice as long as the 1st siibmargiual cell. 

 Described from one specimen, taken probably in Missouri Coll C

Bracon nevadensis u. sp. 



Female.— Length, 3f mm ; ovipositor, lf™». Black, smooth, polished, 

 and sparsely covered with long, sericeous hairs. The head is rather 

 large, subquadrate; orbital line, extending into a wider streak on the 

 cheek back of the eye, a large irregular spot above base of mandibles, 

 clypeus and mandibles, the parapsidal grooves, tegulre and the trian- 

 gular piece in front, scutellum, mesopleune, metapleuras, legs, lateral 

 margins of 1st abdominal segment, the 2d, except a black spot back of 

 the plate of 1st segment, the basal half of the 3d, and a slight streak 

 at the base of the 4th widened at lateral margins, all red, or reddish- 

 brown. The antennae are broken at tips, but of the remaining portion, 

 28 joints can be counted; the flagellar joints are not much longer than 

 wide ; maxillary and labial palpi, black ; parapsidal grooves not sharply 

 defined, smooth, lined with hairs ; the groove at base of scutellum 

 crenulated ; metathorax smooth, with indications of a median carina 

 posteriorly, very hairy; mesopleuras smooth, polished; the sternum and 

 the middle and posterior coxae, beneath, are black; there is a black 

 streak along the under surface of the middle femora, and their tibia? 

 ami tarsi are dusky; the 2d joint of posterior trochanters and posterior 

 tibia? and tarsi, are black. 



The abdomen is ovate, the plate of 1st segment quadrate, roughened, 

 keeled laterally; the 2d and basal half of 3d segments aciculated ; fol- 

 lowing segments polished. Wings, dusky hyaline, iridescent, stigma 

 and veins brown; the venation is similar to B. phyeidis. 



Habitat. — Nevada County, California. 



Described from one specimen, collected by Mr. A. Koebele, September 

 3, 1885. 



Bracon gelechiae n. sp. 



Male and female. — Length, 24- mm ; ovipositor, f mm . Black, subopaqne, 

 delicately shagreened and sparsely pubescent ; anterior and superior 

 orbits, lateral margins of 1st abdominal segments, and sometimes the 

 2d segment, except a black streak down the middle, and the 3d, 

 4th, and 5th segments laterally, venter, palpi, trochanters, apices of 

 femora and tibiae, with all the tarsi, honey-yellow. 



The antennas are 26-joiuted ; parapsidal grooves wanting. Wings, 

 hyaline; veius, brown; the median transverse nervure is interstitial 

 with the basal nervure; the 1st discoidal cell petiolate; the recurrent 

 nervure joins the 1st submarginal cell about two-thirds its length, the 

 1st branch of the radius being about as long as the 1st transverse 

 cubital nervure, which is oblique, the upper margin of the 2d submar- 

 ginal cell being therefore about half the length of the lower margin.
