Diagnosis: Differs from placida, timberlakei, and verecunda by the presence of white instead of yellow maculations. Differs from snowii by the lack of ferruginous markings on the legs or thorax and broken transverse median maculations on the abdominal terga. Differs from mutans by the presence of a strong denticle on the pro-coxae, a prominent scutellum which is not flattened or highly polished, and the shelf�like supra-spiracular ridge. It differs from most mutans by having the first tergum all black and several terga with medially interrupted transverse maculations.
Male: Length 6.3-9.4 mm, forewing length 4.7-6.2 mm, hindwing length 3.8-4.9 mm; scape densely, almost contiguously punctured, IPS shiny, somewhat sha-greened; IOD 0.31 mm, OOD 0.38 mm, MLOD 0.09 mm, MOD 0.17 mm, MOOM 0.39 mm; IPS within ocellar triangle roughened; labrum with broken subapical trans�verse carina; acetabular carina distinctly lamellate; pre-lobar carina sharp, gently sloping; pronotal ridge with abruptly angulate, deeply punctate apex; tegulae very sparsely punctate, glassy; scutellum protruberant, bilobate, coarsely punctate, scuto-scutellar suture deeply depressed, posterior interpunctural surface coarsely, transversely micro-rugose; propodeal sides with very rough IPS, supraspiracular ridge strong, forming distinct flattened shelf above spiracular opening, distinct verti-cal groove posterior to spiracle; metapleuron with ventral half shallowly punctate; short but stout pro-coxal spine rudiment present; hind tibial apex with 5 bristles, pos�terior 2 clear and quite thin; forewing with 3 submarginal cells (left wing of type with incomplete 1st intercubitus), infuscated with clear subapical crescent: COLOR: lower half of clypeus, sides of face along compound eyes halfway to antennal inser�tion, malar space, basal half of mandibles, labrum (in part), pronotal lobes, lateral spots on tegulae, apex of scutellar lobes, apical and basal portions of tibiae, apex of hind-femora, lateral median triangular patches on terga 2-4, complete transverse median bands on terga 5-6, apical lateral crescents on sterna 3-5, creamy-white; an�tennae ferruginous; remainder of body dark brown to black.

�Length hardly 6 millim.
Black, with cream-coloured markings ; abdomen broad
and quite small. Facial quadrangle square, the orbits
parallel ; eyes pale grey ; anterior half of clypeus, triangular
lateral marks short and blunt above, and broad base of mandibles
cream-colour; mandibles simple; labrum dark, very
densely punctured ; antennae dark brown above, ferruginous
beneath ; third joint a little longer than fourth, paler and less
shining than rest of flagellum ; cheeks wholly black ; mesothorax
extremely densely punctured ; the cream-coloured
tubercles offer the only light marking on thorax ; scute-Hum
hardly bilobed ; tegulse testaceous, with a small creamcoloured
spot. Wings irregularly stained with brown ; nervures
dark ; transverso-medial nervure joining discoidal at
its base. Legs black, anterior femora and tibiae in front and
anterior tarsi pale ferruginous; middle and hind tibia? at
base, spot near apex of middle tibiae, and large wedge-shaped
mark on apical portion of hind tibiae cream-colour; hair on
inner side of basal joint of hind tarsi very pale golden. Abdomen
with shallow punctures ; first segment black, second to
fourth with a large wedge-shaped cream-coloured mark on
each side, fifth and sixth with bands ; posterior margins of
third and following segments reddish ; apical plate not at all emarginate; apical portion of venter with three light bands,
the first two very broadly interrupted in the middle.
The markings of the hind tibiae and the immaculate metathorax
suggest N. verecunda, which, however, is a different
thing.

Diagnosis: Differs from placida, timberlakei, and verecunda by the presence of white instead of yellow maculations. Differs from snowii by the lack of ferruginous markings on the legs or thorax and broken transverse median maculations on the abdominal terga. Differs from mutans by the presence of a strong denticle on the pro-coxae, a prominent scutellum which is not flattened or highly polished, and the shelf�like supra-spiracular ridge. It differs from most mutans by having the first tergum all black and several terga with medially interrupted transverse maculations.
Male: Length 6.3-9.4 mm, forewing length 4.7-6.2 mm, hindwing length 3.8-4.9 mm; scape densely, almost contiguously punctured, IPS shiny, somewhat sha-greened; IOD 0.31 mm, OOD 0.38 mm, MLOD 0.09 mm, MOD 0.17 mm, MOOM 0.39 mm; IPS within ocellar triangle roughened; labrum with broken subapical trans�verse carina; acetabular carina distinctly lamellate; pre-lobar carina sharp, gently sloping; pronotal ridge with abruptly angulate, deeply punctate apex; tegulae very sparsely punctate, glassy; scutellum protruberant, bilobate, coarsely punctate, scuto-scutellar suture deeply depressed, posterior interpunctural surface coarsely, transversely micro-rugose; propodeal sides with very rough IPS, supraspiracular ridge strong, forming distinct flattened shelf above spiracular opening, distinct verti�cal groove posterior to spiracle; metapleuron with ventral half shallowly punctate; short but stout pro-coxal spine rudiment present; hind tibial apex with 5 bristles, pos�terior 2 clear and quite thin; forewing with 3 submarginal cells (left wing of type with incomplete 1st intercubitus), infuscated with clear subapical crescent: COLOR: lower half of clypeus, sides of face along compound eyes halfway to antennal inser�tion, malar space, basal half of mandibles, labrum (in part), pronotal lobes, lateral spots on tegulae, apex of scutellar lobes, apical and basal portions of tibiae, apex of hind-femora, lateral median triangular patches on terga 2-4, complete transverse median bands on terga 5-6, apical lateral crescents on sterna 3-5, creamy-white; an-tennae ferruginous; remainder of body dark brown to black.
Female: Length 6.2-8.1 mm, forewing length 5.1-5.6 mm, hindwing length 4.2-4.4 mm; very similar to male.
Discussion: This species is widely distributed along the Rocky Mountains. It has the most strongly developed pro-coxal spines of any of the North American species, but they are not as pronounced as those of the Eurasian species.

sparse punctures. Wings fairly clear, the broadly darkened
apical margin strongly contrasting ; stigma very dark reddish, nervures piceous ; second submarginal cell broad above. Legs
red, with little black, but the middle femora at base and the hind femora behind are conspicuously blackened ; hair on
inner side of basal joint of hind tarsi pale golden ; a trilobed black mark at base of first abdominal segment.
MALE —Length hardly 6 millim.
Black, with cream-coloured markings ; abdomen broad
and quite small. Facial quadrangle square, the orbits parallel ; eyes pale grey ; anterior half of clypeus, triangular
lateral marks short and blunt above, and broad base of mandibles cream-colour; mandibles simple; labrum dark, very
densely punctured ; antennae dark brown above, ferruginous
beneath ; third joint a little longer than fourth, paler and less shining than rest of flagellum ; cheeks wholly black ; mesothorax extremely densely punctured ; the cream-coloured
tubercles offer the only light marking on thorax ; scuteum hardly bilobed ; tegulse testaceous, with a small creamcoloured spot. Wings irregularly stained with brown ; nervures dark ; transverso-medial nervure joining discoidal at
its base. Legs black, anterior femora and tibiae in front and
anterior tarsi pale ferruginous; middle and hind tibia? at base, spot near apex of middle tibiae, and large wedge-shaped
mark on apical portion of hind tibiae cream-colour; hair on
inner side of basal joint of hind tarsi very pale golden. Abdo- men with shallow punctures ; first segment black, second to fourth with a large wedge-shaped cream-coloured mark on
each side, fifth and sixth with bands ; posterior margins of
third and following segments reddish ; apical plate not at all emarginate; apical portion of venter with three light bands,
