Nomada (Asteronomada) adducta Cresson NEW COMBINATION Nomada ad�ducta Cresson, 1878. American Hymenoptera 73. Holotype, male: "Col., 2591". Type Depository, Academy of Natural Sciences of Philadelphia.
Diagnosis: Differs from portalensis and durangoae by the presence of a densely punctate, globose antennal scape in males. Differs from portalensis by the narrow apical impunctate band of tergum 3. Differs from durangoae and brewsterae by the lack of a prominent raised, transverse ridge behind the ocellar triangle.
Male: Length 8.9-10.3 mm, forewinglength 6.4-6.9 mm, hindwinglength 5.0-5.2 mm; antennal scape globose, heavily punctate, smooth, shiny IPS, posterior densely micro-punctate; IOD 0.44 mm, OOD 0.46 mm, MLOD 0.17 mm, MOD 0.20 mm, MOOM 0.54 mm; occipital margin smoothly rounded; labrum with broken trans�verse subapical carina, and median nipple; acetabular carina strongly lamellate; pre-lobar carina sharp, short; pronotal ridge strongly angulate apically; scutum deeply reticulately punctured; scutellum distinctly bilobate, postero-medial region with roughened, dull IPS; metanotum flattened; hind coxae and sides of propodeum cov�ered with short, densely appressed, plumose hairs; ventral metapleuron punctate; pro-coxal spine rudiment lacking; hind tibial apex with 4 stout, ferruginous bristles; basitarsus not medially inflated, angulate anterior margin; forewing with 3 submargi-nal cells, apices slightly infuscated: COLOR: rufous; clypeus, sides of face, labrum, basal half of mandibles, creamy-yellow; pronotal ridge and lobes, tegulae, metano-tum, scutellum, legs, ferruginous; propodeum dark ferruginous; vertex and apical tergal segments fuscous.
Female: Length 8.7-10.4 mm, forewing length 6.1-7.3 mm, hindwing length 4.6-6.1; facial markings more ferruginous than yellow. Antennal scape not globose.
Discussion: This species is widely distributed, but uncommon. This may be due in part to its late season of flight when most collectors are not active. From brief field observations, its behavior patterns seem similar to Pachynomada (pers. obs.), and it is often collected in the same areas.

Head ferruginous,closely punctured; large spot
on vertex extending more narrowly back to occiput covering ocelli, posterior
margin of head and tips of mandibles, black ; sides of face, clypeus and base of
mandibles, yellow; antenna rather short, fuscous, paler beneath, scape short,
dilated, ferruginous at base; third joint slightly longer than fourth; thorax
black, densely and strongly punctured; a largo mark on each side of meso
thorax, the scutellums and most of pleura, ferruginous; scutellum bilohate;
metathorax not distinctly sculptured, the sides with patch of silvery pile; an
obscure yellowish line on each side of collar ; tegula and tubercles, ferruginous ;
wings hyaline, fuscous at extreme tips; legs ferruginous, base of coxa and of
femora more or less,spot at tip of posterior tibia and base of their tarsi, black;
abdomen closely punctured, ferruginous, immaculate except a black band on
first segment and a dusky spot on each side of second; extreme lateral apical
margin of the segments and apex with white pubescence. Length .3ft inch.
