Overview

FEMALE—Length 8 mm.; black; pubescence whitish, rather thin; head much broader than long; clypeus only slightly convex, projecting about one-half below suborbital line; eyes very slightly convergent below; cheeks slightly broader than eyes; lateral ocelli very slightly nearer margin of vertex than to eyes; face above antennae dull, finely rugoso-punctate, punctures below antennae well separated on supraclypeal area and upper margin of clypeus, becoming more coarse and sparse on clypeus apically, area between eyes and ocelli rather dull, punctures hardly evident; vertex dull medially, obscurely striate, cheeks somewhat shining, very minutely and obscurely punctate above, becoming finely striate below; scutum with a quite deep, median, anterior groove, rather dull, punctures quite deep and distinct, will separated over median area of disc, becoming rather close laterally and posteriorly, but much finer and more obscure anteriorly; scutellum rather dull, with a slight, more closely punctate median impression, the punctures variable and scattered on each side of this; pleura dull, rather finely and uniformly rugoso-striate; dorsal area of propodeum rugoso-striate, posterior face somewhat shining, shallowly reticulate, the lateral carinae strongly divergent, quite short; wings subhyaline, veins and stigma testaceous; tegulae reddish-testaceous, with whitish-hyaline anterior rim; legs somewhat reddened, becoming more definitely ferruginous on apical tarsal segments, hind basitibial plate rather small, triangular, subacute; abdominal terga shining, punctures very fine and indistinct, these very sparse and obscure on basal segment, rather close and more distinct on tergum 2 basally but becoming very sparse and obscure apically and on terga 3 and 4, basal white fasciae on terga 2 and 3 evident laterally, discal pubescence extremely short, thin and obscure, entirely white.

MALE—Length 8 mm.; black, clypeus apically and mandibles in part, yellow; pubescence whitish, very thin and quite short in general, but lower portion of face quite densely tomentose; head considerably broader than long; clypeus slightly convex, projecting nearly one- half below suborbital line; eyes rather strongly convergent below; mandibles dark at extreme base, yellowish medially, the elongate apex reddish; labrum dark, subtriangular; cheeks very slightly narrower than eyes; lateral ocelli very slightly nearer margin of vertex than to eyes; basal segment of flagellum, very short, barely exceeding pedicel in length, second and following segments elongate, fully twice as long as broad, piceous below, blackish above; face above antennae dull, very densely rugosopunctate, lower portion of face somewhat more shining beneath the pubescence, punctures deep and distinct but rather close on supraclypeal area, clypeus with rather fine, close and deep punctures basally, these becoming much more coarse and sparse apically, area between eyes and ocelli roughened, obscurely punctate; vertex medially rather dull, obscurely striate, the cheeks largely striate; scutum shining, punctures deep and distinct, well separated medially, becoming rather fine and close but not crowded laterally, obscure anteriorly where the surface is dull and tessellate; scutellum shining, with a rather deep, median groove, somewhat protuberant on each side of this, punctures rather fine and close but not crowded; pleura densely and rather finely rugose above, becoming smooth and somewhat shining below; dorsal area of propodeum coarsely striate, posterior face coarsely reticulate, the lateral carinae strongly divergent but rather obscure, incomplete; wings hyaline, veins and stigma testaceous; tegulae piceous, anterior rim narrowly yellowish-testaceous; legs dark, but the more basal tarsal segments bright yellow, these becoming darker apically; abdominal terga shining, quite deeply but very finely punctate, the punctures distinctly but not widely separated on basal segment, somewhat closer on the second and following segments basally, but becoming more minute and sparse apically, the basal, whitish fasciae very thin and inconspicuous, discal pubescence hardly evident; apical margin of sternum 5 straight, 6 broadly rounded; gonostylus simple, consisting only of a rather short, somewhat compressed, apical lobe which is thinly clothed with very fine, inconspicuous pubescence, no ventral, retrorse lobe evident.

DISTRIBUTION—Minnesota to Quebec and the New England states, south to North Carolina; May to September.

FLOWER RECORDS — Eupatorium, Rhus, Solidago and Viburnum. A specimen of Halictus adelipus Vachal, probably the type, in the Paris Museum, has been examined, and seems to lie within the range of variation of cinctipes.


Identification
This is a large species, 8-9mm, much closer in size to the Lasioglossum sensu strictu than the other black species groups. In the female there can be a substantial band of appressed white hairs at the base of T2-3, taking up to one third of the segment, but commonly it is narrower and is partially covered by the preceeding tergite and thus just the white patches of hair at the sides show.
