Viereck — New Genus and Species of Ichneumon- Flies. 169 



most of fore coxae, fore and mid trochanters and distal, hind trochanter 

 yellow, wings with a brownish tinge, stigma and veins brownish stra- 

 mineous, the latter darker than the former, venation as in Sagaritis 

 provancheri D. T., i. e., with the recurrent vein received by the areolet 

 a little before the middle, areolet petiolate and with the second abscissa of 

 the discoidal vein longer than the third, all femora reddish, rest of fore 

 legs brownish stramineous, the coxae which are mostly black, in the tarsi 

 which are mostly fuscous and in the tibiae which have a subbasal and an 

 apical dark brownish band, hind legs with their coxae and proximal 

 trochanters mostly black, their tibiae yellowish with a subbasal and an 

 apical brownish fuscous stain, their tarsi fuscous, their tibial spurs whit- 

 ish ; propodeum shining, witii poorly defined punctures and well developed 

 carinae, basal area sessile almost triangular, costulae complete, areola and 

 petiolarea confluent, the petiolarea rugulose; abdomen black, with the 

 apical edge of the second tergite yellowish, the vertical sides of the third 

 to sixth tergites and all of the seventli tergite mostly reddish, third to 

 sixth tergites dorsally with a brownish apical margin, petiole convex, with 

 a distinct fossa on each side near the postpetiole, distance from the base 

 of the petiole to the spiracle apparently twice the distance from the latter 

 to the apex of the first tergite, the latter distance distinctly greater than 

 the distance between the spiracles, postpetiole convex, apex of petiole 

 with a median impression, second tergite with the thyridii elongate and 

 nearer the lateral edge than to the base of the segment, spiracles of second 

 tergite almost adjoining the lateral edge and half way between base and 

 apex ; sheaths of the ovipositor nearly as long as the first tergite. 



A paratype from Wallops Island, Virginia, June 1, 1913, W. L. McAtee, 

 has reddish color of the third tergite more extensive and fusing on the 

 dorsum and the antennae 30-jointed. 



Neogreenia Viereck. 



This genus was described from a single female specimen collected in 

 Pennsylvania. A study of a series of specimens of both sexes from Mary- 

 land and Virginia makes it certain that the transverse cubitus is some- 

 times present though less than half the length of the abscissa of the 

 cubitus between the transverse cubitus and the recurrent vein and 

 that in some specimens there are three abscissae to the discoidal vein, 

 the second abscissa of the discoidal vein being in such cases less than 

 half the length of the nervulus. The nervulus is sometimes interstitial 

 with the basal vein although usually received by the discocubital cell a 

 little beyond the basal vein, 



Neogreenia picticornis Viereck. 



Male. Collection Nathan Banks: Agrees with the type except in 

 the antennae, which are uniformly blackish without a whitish annulus, 

 flagel 21-jointed ; hind coxae blackish with stramineous tips. In both 

 sexes the mesonotum is in some specimens mostly reddish and the base 

 of the flagel yellowish. In one female the petiole is stramineous with the
