FEMALE-Length 9 mm.; head and thorax
black, abdomen ferruginous, the apical segment black; head much broader than long;
eyes slightly convergent below; clypeus short
and broad, slightly convex on each side of a
median, longitudinal depression; labrum subtriangular, the rounded apex rather deeply incised medially, blackish in color; mandibles
elongate, slender, entirely simple, more or
less ferruginous except at base; antennae
dark, flagella enly obscurely reddish-piceous,
basal segment relatively long, much longer than
pedicel, and slightly longer than broad, the
following segments somewhat broader than
long; lateral ocelli subequally distant from
eyes and each other; face below ocelli deeply,
distinctly, closely and rather coarsely punctate, those below antennae close and coarse
also but more or less obscured by pubescence,
the supraclypeal area closely, deeply and rather finely punctate, punctures on clypeus
close in general, fine along upper margin and
in median depression, becoming rather coarse
on each side; vertex closely and rather finely
punctate between eyes and ocelli, becoming
more rugose along hind margin and rugosostriate on cheeks, these shining on lower surface, with a few obscure, shallow punctures;
wings lightly infuscated, with the usual three
submarginal cells, veins and stigma brownishpiceous; tegulae yellowish-hyaline; legs black;
scutum and scutellum somewhat shining between irregular but generally coarse, close
and deep punctures, these becoming finer and
closer on scutum laterally, anterior margin
becoming very finely but densely rugose, punctures on scutellum very coarse and quite close
and irregular; pleura coarsely reticulate; dorsal area of propodeum coarsely rugoso-striate,
lateral faces relatively smooth but dull, becoming coarsely reticulate posteriorly, posterior face coarsely reticulate; abdominal
terga smooth and shining, basal tergum almost
impunctate, 2 and 3 rather finely and closely
punctate across basal half, punctures becoming finer and closer toward sides, and more
course and sparse on the more apical terga,
those on the blackened 5th quite close and
rather course and deep, apical half of 2 and
3 practically impunctate, the impressed apical
margin somewhat paler in color, entirely impunctate.
MALE-Length 7 mm.; entirely black; head
considerably broader than long; eyes slightly
convergent below; clypeus convex, with a
slight median impression ; mandibles ferruginous apically; antennae black basally, becoming more brownish-piceous apically, scape
short, segment 2 of flagellum much broader
than long and nearly twice as long as pedicel,
3 longer than 2, the following approximakly
equal to the first in length, 4th and following
segments with basal, densely pilose, semicircular facets beneath, these becoming slightly
more extensive on the more apical segments,
but very short in all; lateral ocelli subequally
distant from eyes and each &her; lower portion of face obscured by dense, white pubescence, clypeus more or less exposed, punctures fine, deep, distinct and uniformly crowded, those above antennae coarse, deep, distinct
and very close, becoming slightly separated
between eyes and ocelli, hind margin of vertex becoming rather coarsely reticulate; cheeks
rather finely rugoso-striate, above, becoming
more distinctly striate posteriorly and below,
but lower surface shining and rather smooth;
wings hyaline basally, becoming lightly infuscated apically, with the usual three submarginal cells, veins testaceous, stigma more
brownish-piceous; tegulae testaceous-hyaline,
becoming almost whitish anteriorly, with a
few fine and obscure punctures; legs blackish
basally, tarsi brownish-testaceous; scutum and
scutellum rather dull, punctures coarse and
deep, close over most of scutum, becoming
rugoso-punctate along anterior margin, scutellum with very coarse and slightly separated punctures on each side of a wry slight, median
impression; pleura coarsely reticulate; dorsal area of propodeum quite broad, wry coarsely
and completely rugoso-striate, lateral faces
dull, very finely substriate anteriorly, becoming
coarsely reticulate along posterior margin,
and posterior face rather finely rugoso-striate;
abdominal terga shining, basal tergum with
but a very few minute and obscure punctures
scattered across median portion of disc, terga
2 and 3 with fine but deep and distinct punctures, these rather close over basal half of
2, becoming sparse apically, 3 more fully
punctate, the apical impressed areas of all
terga rather broad, entirely impunctate, con- colorus with remainder of discs; gonostyli
(fig. 117) rather short and robust, only slightly exceeding penis valves, outer surface broadly convex, more or less excavated on inner sur- face, apex acute.
DISTRIBUTION-Minnesota to Nova
Scotia, south to Texas and Georgia; March
to August.
FLOWER RECORDS-Cicuta maeulata.
This species is recorded by Robertson
(1929) (as Drepanium falciferum) on Asclepias, Ptelea, Pycnanthemum, Rhus and
