6*50 NEW SPECIES OF BRACONID^. 



DACNUSA Haliday. 



Dacnusa oscinidis n. sp. 



Male and female. — Length, If""". Black, smooth, polished ; two basal 

 antennal joints, palpi, and legs, honey-yellow; the 1st and two-thirds 

 of the 2d abdominal segments reddish-yellow : antenna) in male 24- 

 jointed (broken in female), cylindrical, very pubescent; the 1st joint 

 of the llagellum is longer than the 2d, the following joints about four 

 times as long as wide; thorax ovoid, smooth, polished, without grooves; 

 metathorax minutely sculptured, pubescent; abdomen oval, the 1st 

 segment finely aciculated and keeled. Wings hyaline, iridescent; 

 veins pale brown ; the stigma very large, lanceolate, the marginal nerv- 

 ure springing from before its middle, the 1st branch of which is shorter 

 than the 1st transverse cubital nervure, the 2d branch curving and ex- 

 tending to the apex of the wing, forming a very large marginal cell ; 

 the 1st submarginal and the 1st discoidal cells are rather small and 

 about the same size ; the submedian cell is longer than the median. 



Habitat. — Kirkwood, Missouri. 



Described from two specimens, one male and one female, received 

 from Miss M. E. Mnrtfeldt, labeled "Parasite on dipterous miner, Os- 

 cinis sp. on honey-suckle, April G, 188.J." 



Dacnusa confusa u. sp. 



Male. — Length, 2| mm . Black, polished ; two basal joints of antennas 

 and legs, honey-yellow; tarsi dusky. Antennas 30-jointed, cylindrical, 

 the 1st joint of the flagellum is the longest, slightly longer than the 2d, 

 the following joints after the 3d are about twice as long as wide ; thorax 

 ovoid, without parapsidal grooves, but there is a deep longitudinal 

 medial groove posteriorly; in one specimen this groove extends nearly 

 the whole length of the mesonotum, in the other hardly half the length; 

 the scutellum has a large, deep, transverse fovea aeross the base, sep- 

 arated into two parts by a delicate carina and with some raised lines 

 at the bottom ; mesopleura pubescent with a glabrous spot on the disk; 

 mesothorax minutely rugose with a short keel back of the post-scutel- 

 lum ; abdomen oval, depressed, the 1st segment is rugose, the tubercles 

 somewhat prominent, the following segments smooth, polished. Wings 

 hyaline, iridescent; the stigma and veins brown; the stigma is long, 

 lanceolate; the 1st branch of the radius is slightly shorter than the 

 transverse cubital nervure, the 1st submarginal cell is a little larger 

 than the 1st discoidal. 



Habitat. — Monroe, Michigan. 



Described from two specimens, labeled No. 2464 oa ; reared from alepi- 

 dopterous leaf-miner on rose. 



I doubt the correctness of this statement, and rather surmise that this 

 was a dipterous and not a lepidopterous leaf-miner, as all other Hacnusev 

 known to me have been reared from dipterous larva' ; unity of habit 

 would therefore exclude the genuineness of this observation.
