FEMALE—Length 6-7 mm.; black; pubescence whitish, very short and thin; head very slightly longer than broad; clypeus slightly convex, projecting nearly two-thirds below suborbital line; eyes converging below; cheeks slightly narrower than eyes; lateral ocelli much nearer margin of vertex than to eyes; face above antennae dull, densely rugoso-punctate, more shining below, punctures distinctly separate but not sparse, close on upper portion of clypeus, becoming much more coarse and sparse apically; area between eyes and ocelli shining, punctures very fine and distinct, vertex medially dull, finely and obscurely striate, cheeks more shining, very minutely and obscurely punctate above, becoming substriate below; scutum shining, punctures deep, distinct and rather close, those on median area becoming somewhat finer and closer laterally; scutellum shining, very sparsely punctate on each side of a median, more closely punctate impression; pleura smooth, somewhat shining, with scattered, obscure punctures; dorsal area of propodeum with a basal fringe of short striae, smooth and rounded apically, posterior face rather dull, very minutely substriate, lateral carinae strongly divergent, very short; wings subhyaline, veins and stigma brownish-testaceous; tegulae reddish-piceous, with a narrow, hyaline, anterior rim; legs dark, becoming more or less reddened apically; hind basitibial plate rather obscure, obliquely truncate apically; abdominal terga somewhat shining, very minutely and obscurely punctate, punctures on basal tergum rather close in median area of disc, but very sparse basally and apically, those on second and following terga progressively more minute and obscure, basal fasciae of terga 2 and 3 evident laterally, discal pubescence extremely short and thin, entirely pale.

MALE—Length 5-6 mm.; black, including labrum and legs in large part, clypeus more or less yellowish apically and mandibles and tarsi yellow at least in part; head considerably longer than broad; clypeus narrow, protuberant, projecting fully two-thirds below suborbital line; eyes convergent below; mandibles simple, rather short; labrum transverse, apical margin not angulate; cheeks narrower than eyes; lateral ocelli slightly nearer margin of vertex than to eyes; basal segment of flagellum very slightly longer than pedicel and slightly broader than long, the 2nd and following segments fully twice this length, brownish-testaceous below, piceous above; face above antennae dull, densely and finely rugose, lower portion more shining, with fine but distinct punctures largely obscured by dense, pale tomentum; area between eyes and ocelli rather dull, with minute, rather close and obscure punctures; vertex medially dull, obscurely roughened, cheeks more shining, punctures above very minute and obscure, hardly evident, becoming very finely substriate below; scutum shining, very finely punctate, punctures rather widely separated in central area of disc and only slightly closer at extreme sides, surface rather dull along anterior margin; scutellum polished, very sparsely and minutely punctate; pleura dull, very finely rugose anteriorly, becoming quite smooth and obscurely punctate posteriorly; dorsal area of propodeum with a basal fringe of short striae, but these complete laterally, becoming quite smooth and obscurely and minutely punctate, lateral carinae hardly evident; wings hyaline, veins and stigma brownish-piceous; tegulae shining, yellowishhyaline with dark blotches, anterior rim more distinctly hyaline; legs dark, apical tarsal segments becoming more or less yellowish; abdominal terga shining, punctures minute but quite distinct, well separated but not sparse on the more basal terga, becoming exceedingly minute and indistinct on terga 3-5, basal fasciae hardly evident; apical margin of sternum 5 straight, 6 broadly rounded; gonostylus short, quite narrow, clothed with inconspicuous, short setae, ventral, retrorse lobe quite short, very slender, with a slightly dilated base, partially clothed with very fine, short pubescence.

DISTRIBUTION—Nova Scotia to Manitoba and Minnesota, south to Georgia; April to September.

FLOWER RECORDS—Acer, Amelanchier, Apocynum, Barbarea, Brassica, Houstonia purpurea, Hydrangea, Malus, Malilotus, Potentilla, Rhus, Rubus, Taraxacum and Vicia. Robertson (1929) records foxii on the following additional genera: Antennaria, Arabis, Aruneus, Aster, Caealia, Capsella, Claytonia, Coreopsis, Cornus, Cryptotaenia, Dent aria, Erigenia, Geum, Isopyrum, Ozalis, Rhamnus, Ribes, Salix, Sanguinaria, Sanieula, Stellaria, Symphoriearpus, Taenidia, Viburnum, Viola, Zanthoxylum and Zizia. It is recorded by Brittain and Newton (1933-34) also on Aralia, Cirsium, Diervilla, Phleum, Rhododendron, Solidago, Trifolium and Vaccinium.

The lack or striations or reticulations going to the rim distinguish both the male and female of this species from the similar but more northern L. rufitarse. The rim of the propodeal triangle noticably smooth in both sexes.
