stiginal long-, straig-ht, with a small knob at apex, abont two-fifths as 
long as the postmarg-inal. 
One Specimen, sent by my friend Mr. J. R. de la Torre Biieno, 
collected at Van Cortlandt Park, New York City. 
This species can be distinguished from H. floridana Ashmead, 
the only other one known from the United States, by its longer 
and more slender antennae. It is the only species known to ex- 
tend so far north in its range, most members of the genus belong- 
ing to the neotropical region.

Oxytorus paludicola, sp. nov. 
Male. Leng-th .5 — 6 mm. Black; antennsje fuscous, most of legs 
and abdomen ferrnginous. Head not quite twice as wide as thick, 
rather thickly hairy ; subshining, the vertex, occiput, and cheeks 
faintly punctulate ; face finely rugoso-punctate, distinctly produced 
below the base of the antennae. Clypeus distinctly separated from the 
face, broad, itg anterior margin truncate. Eyes elongate, very sparsely 
pilose, with not the slightest trace of an emargination between the 
antenna?. Antennae stout and tapering, shortly pilose, 26-28 jointed, 
similar to those of certain Orthocentrine genera. Scape stout, oval ; 
first flagellar joint distinctly longer than the second, which is twice as 
long as thick ; following growing imj)erceptibly shorter and narrower, 
those near the tip quadrate. Mesonotum with the parapsidal furrows 
well marked, its surface punctulate on the sides, with the median lobe 
more coarseh' punctate, especialh' behind, where it is confluently so. 
Scutellum with a wide deep fovea at the base divided by a median 
carina, apically convex and punctulate. Metathorax completely areo- 
lated, the lateral angles of the j^etiolar area produced as distinct teeth. 
Petiolar area transversely striate, the other areas rugose. Epomial 
carina of propleura distinct. Abdomen distinctly petiolate, smooth 
and shining, the petiole curved, more stronglj^ so at the center ; 
spiracles placed distinctly behind the center, where they give off lateral 
carinas to the tip; two very strongly elevated median carinae which
