FEMALE-Length 5 mm.; head and thorax
shining black, abdomen ferruginous basally,
the apical half blackened; head much broader
than long; eyes slightly convergent below; clypeus broadly convex; labrum rather short and
broad, broadly rounded, dull reddish apically,
becoming somewhat darker at base; mandibles
with a distinct and rather robust, inner, subapical tooth, testaceous medially, becoming
piceous at base and reddened at tip; antennae
blackish basally, the flagellum dull brownishferruginous beneath, more piceous above, the
more basal segments of the flagellum somewhat broader than long, these becoming longer
apically where the length slightly exceeds the
breadth; lateral ocelli slightly nearer to each
other than to eyes; face below ocelli shining,
punctures very fine but deep, distinct and
widely separated, almost sparse, becoming
relatively close but more shallow and obscure
below, supraclypeal area slightly elevated,
punctures wry fine, irregular, slightly separated, those on clypeus fine and rather close
along upper margin, becoming somewhat more
coarse, deep and much more sparse apically;
vertex between eyes and ocelli polished, punctures minute and sparse, hind margin becoming rather coarsely, transversely striate,
cheeks above rather dull, finely striate, becoming rather smooth and shining below; wings
subhyaline, with the usual three submarginal
cells, veins and stigma brownish-testaceous;
tegulae brownish-testaceous; legs piceous basally, becoming more brownish-testaceous on
tarsi; scutum and scutellum polished, punctures deep and distinct but very fine and
widely separated, even between notaulices and
tegulae, those on scutellum also very sparse;
pleura dull, quite densely rugosre; dorsal area
of propodeum quite broad, completely and
rather coarsely rugoso-striate, lateral and posterior faces rather coarsely reticulate; abdominal terga smooth and shining, basal tergum entirely impunctate, terga 2 and 3 with
a few scattered, rather sparse, exceedingly minute and obscure punctures toward base, apical margins of all rather broadly impressed,
impunctate, those of terga 1 and 2 yellowishhyaline, the others only very narrowly so
along the rims.
MALE-Length 6 mm.; head and thorax
black, basal segment of abdomen piceous in
large part, becoming ferruginous along apical
margin. terga 2 and 3 ferruninous in art.
apical tergaV black; head muclh broader than
long; eyes slightly convergent below; clypeus
broadly convex; mandibles dark basally, becoming brownish-testaceous apically, but the
tip reddened; antennae black basally, flagellum brownish beneath, becoming somewhat
more piceous above, basal segment about as
broad as long, 2nd and following segments
nearly twice this length, entirely simpre; lateral ocelli subequally distant from eyes and
each other; lower half of face, including clypeus, obscured by dense, white pubescence,
upper portion above antennae quite coarsely
and deeply punctate, punctures crowded medially, becoming somewhat more .distinct laterally, those on vertex between eyes and ocelli
very fine and rather obscure, well separated,
hind margin becoming irregularly, transversely striate; cheeks striate, with ventral surface
somewhat smoother but rather dull; wings
subhyaline, with the usual three submarginal
cells, veins and stigma testaceous; tegulae
yellowish-hyaline; legs piceous basally, front
tibia and all tarsi yellowish-testaceous; scutum and scutellum somewhat shining between
rather coarse and deep punctures, these rather
widely separated over most of scutum, even
between notaulices and tegulae, becoming close
or more rugose along anterior margin, those
on scutellum quite sparse; pleura coarsely rugose; dorsal area of propodeum quite broad,
rather finely reticulate medially, becoming
more regularly striate laterally, lateral faces
very finely and irregularly striate anteriorly,
becoming coarsely reticulate posteriorly, posterior face coarsely reticulate; abdominal terga polished, punctures exceedingly minute,
basal tergum practically impunctate. terna 2 - - 7 - and 3 with a few minute, obscure, sparse punctures across base, apical half practically impunctate, apical impressed areas rather broad,
concolorous with remainder of discs: gonocoxites rather strongly excavated dorsally
toward base, gonostyli slightly exceeding tips
of penis valves, rather strongly compressed,
with a very short and inconspicuous, fingerlike, apical projection which bears a few short,
inconspicuous setae, and with an inner, rather
small, membraneous lobe. (resembling autumnalis, fig. 117, but more slender).
DISTRIBUTION - Minnesota, Ontario
and the New England states; July and
August.
