646 NEW SPECIES OF BRACONIDiE. 



wise the venation is similar to the previously -described species; the 

 veins are yellowish. 



Habitat. — Kirk wood, Missouri. 



Described from a single specimen received from Miss Murtfeldt, la- 

 beled "Parasite on Oelechia prunifoliella, May 15." 



This insect is hardly congeneric with the above species, approaching 

 more closely to the genus Enbadizon. 



The subfamilies Calyptinm and Blacince seem to run into each other, 

 and are with difficulty distinguished from each other, the closed anal 

 cell in the former having but slight value. 



Subfamily ALYSIINiE. 



DIASPASTA Forster. 



In this genus should be placed Ahjsia rudibunda Say. 



APH^ERETA Forster. 

 Aphaereta muscae n. sp. 



Mali andfemale.—Length,2 mm ; ovipositor, f mm . Black, polished; two 

 basal joints of antenna?, mandibles, legs, and 1st abdominal segment 

 honey -yellow ; the head is large, transverse, cheeks piceous; antennae 

 long, 21-jointed, the basal joint swollen, oval; the joints of the flagel- 

 lum are long, cylindrical, the 2d about one-third longer than the 1st, 

 the terminal joint fusiform and stouter than 'the one preceding it; in 

 the male the antennas are longer, 26-jointed ; thorax ovoid, smooth, 

 without grooves; metathorax rugulose posteriorly, and with an acute, 

 short, longitudinal carina basally ; abdomen oval, the 1st segment 

 slightly aciculated. Wings large, broad, the veins pale brown ; the 

 stigma is long and narrow, extending to the apex of the wings; the 

 L'd submargiual cell is very long and narrowed at apex, longer than 

 the length of the basal nervure, the 1st transverse cubital nervure 

 being a little longer than the 1st branch of the marginal nervure and 

 about twice as long as the I'd transverse cubital nervure; the 3d 

 branch of the marginal nervure extends straight across to the apex 

 of the wing, and makes a very large marginal cell. 



Habitat.— Fortress Monroe, Virgiuia, and central Missouri. 



Described from many specimens, in both sexes, labeled No. 4309°, 

 reared July 7, 1888, from the puparium of a Musca collected at Fortress 

 Monroe; and a single male in Riley collection, labeled Central Mis- 

 souri. 



This species or those described below may be the A. (Trichesia) auripes 

 Prow, Faun. Ent. Can., II, p. 537, but 1 can not positively tell, Abbe 

 Provancher's description being so imperfect ; he does not give the 

 number of joints in the antenna', nor describe the venation of the 

 wings ; if his figure of the wing (Fig. 71) is accurately drawn then none 

 of them can be identical.
