I find in my collection a specimen from Forest Hills, Massa-~ 
chusetts, which is evidently a true Heterocola and establishes 
the occurrence of this genus in the Eastern United States. It 
is described below. 
Heterocola americana sp. nov. 
@. Length 28 mm. Black, with the abdomen beyond the middle of 
the petiole ferruginous; scape below, mandibles, lower portion of cly- 
peus, mouth-parts, tegulae and legs, including coxae, honey yellow, 
apical joint of palpi black; ovipositor concolorous with the abdomen, 
its sheaths piceous; wings tinged with brown, stigma and veins dark 
brown. 
Head subopaque, very finely shagreened, more shining on the temples 
and distinctly se on the cheeks. Antennae 20-jointed, inserted midway 
between the vertex and base of clypeus; scape short, only half longer 
and no thicker than the pedicel; flagellum narrow at base, the first 
joint as long as the scape, but only half as thick; second joint two- 
thirds as long as the first, third and following thicker, those toward 
the middle a little longer than wide; clypeus shining, coarsely punc- 
tate. Mandibles long, nearly twice as long as the malar space and 
equalling the width of the eye; labrum elongated, pointed, as long as 
the eye and extending considerably beyond the anterior coxae; maxil- 
lary palpi with four subequal joints, reaching, when extended, almost 
to the middle coxae. 
Mesonotum and scutellum opaque, shagreened, separated by a deep 
punctate groove which is terminated at the sides by a sharp carina 
that extends back over the basal angles of the very convex scutellum. 
Metathorax short, obliquely truncate, with a short basal median carina 
followed by a large area which includes the whole of the posterior 
slope of the metathorax; posterior lateral and pleural areas large, dis- 
tinct; spiracle minute, circular, close to the anterior end of the pleural 
carina; surface of metathorax finely rugulose; pleurae shagreened. 
Abdomen widest at the third segment, acutely narrowed apically; 
petiole slender, scarcely widened to beyond the middle, then suddenly — 
wider, more gradually so near the apex, its spiracles just behind the 
middle; body of abdomen moderately compressed toward apex, its sur- 
face smooth and shining; ovipositor as long as the abdomen with- 
out the petiole. 
Legs moderately slender. Wings with the transverse cubitus short, 
almost punctiform, recurrent nervure received just beyond it; third 
discoidal cell completely closed. 
A single female from Forest Hills, Boston, Massachusetts, 
taken during September, 1913.
