Overview
Reprinted with permission from: Mitchell, T.B. 1962 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 152.

FEMALE—Length 4.5-5.5 mm.; head and thorax black; mandibles and margin of clypeus more or less ferruginous; mid and hind tibial spurs pale yellowish; tegulae dark along inner margin, becoming yellowish-hyaline around the outer margin; wings subhyaline, veins brownish to piceous; antennal flagella dark red beneath, piceous above; discs of abdominal terga black or ferruginous, the depressed apical margins yellowish; cheeks about equal to eyes in width; clypeus quite flat, its median length not much greater than third the distance between eyes (fig. 113); eyes subparallel; mandibles slender and simple; labrum elongate, tapering apically, its median length nearly twice the basal width, apex rather narrowly rounded; length of basal segment of flagellum equal to segments and 3 combined; scutum with a rather deep, median sulcus anteriorly; posterior margin of scutellum slightly impressed medially; apical margins of abdominal terga narrowly but abruptly depressed; punctures of head and thorax rather uniformly coarse, close and deep throughout, becoming somewhat more widely separated, but hardly sparse on venter thorax and lower surface of cheeks laterad of the hypostomal carinae; punctures of discs abdominal terga somewhat finer, densely crowded and quite uniform but somewhat coarser and more distinct laterally than in median area; tergum 5 slightly ridged medially, this area minutely and very densely punctate, lateral punctures becoming quite coarse and deep; median length of pygidium much more then half the basal width, margins carinate, strongly converging apically to the abruptly truncate and rather narrow apical margin; sternum 5 very slightly impressed medially, the apical margin slightly incurved; pubescence of head very short and inconspicuous, hardly evident, with a small amount of appressed pale tomentum around and just above antennae; pronotal collar quite densely pale tomentose, the median sulcus of scutum with a small amount of pale tomentum anteriorly; pleura thinly white pubescent above; lateral areas of scutellum and metanotum densely pale tomentose, the propodeum with a small amount of pale tomentum on each side above; basal abdominal tergum with a pair of lateral, anterior, rounded spots of yellowish tomentuin, and terga 2-4 with transverse, basal, yellowish fasciae that are interrupted medially, apical margins on 1-4 very narrowly pale fasciate at each extreme side; pubescence otherwise very short, inconspicuous and hardly evident.

MALE—Length 4.5-5.5 mm.; head and thorax black, antennal flagella becoming reddish-testaceous apically beneath, piceous above; mandibles becoming reddish apically; mid and hind tibial spurs pale yellowish; inner margin of tegulae dark, outer margin becoming more or less narrowly yellowish-hyaline; wings subhyaline, veins testaceous to piceous; discs of abdominal terga ferruginous or black, apical margins rather narrowly yellowish; cheeks slightly narrower than eyes; clypeus quite flat, its median length slightly more than one-third the distance between eyes below; eyes very slightly convergent below; mandibles slender and simple; labrum as in female; basal segment of flagellum about equal to segments 2 and 3 combined; sculpture differing but little from that of female, scuturn with a rather deep, median sulcus anteriorly, posterior margin of scutellum slightly impressed medially; apical margins of abdominal terga narrowly but abruptly depressed; punctures of head and thorax rather uniformly coarse, close and deep throughout, becoming somewhat more widely separated but hardly sparse on venter of thorax and lower surface of cheeks laterad of the hypostomal carinae; punctures of discs of abdominal terga somewhat finer, densely crowded and quite uniform but somewhat coarser and more distinct laterally than in median area; tergum 5 slightly ridged medially, this area minutely and very densely punctate, lateral punctures becoming quite coarse and deep; median length of pygidial plate only slightly greater than basal width, margins strongly carinate, nearly parallel, apex broadly rounded; pattern of pubescence as in female; sterna 7 and 8 and genital armature as shown (fig. 114).


DISTRIBUTION—Illinois to Massachusetts, south to Georgia, May to August.
FLOWER RECORDS—Ceanothus, Chrysanthemum, Erigeron and Oenothera. Robertson (1929) records it also on Coreopsis, Geum, Lespedeza and Pycnanthemum.
The holotype of Neopasites punctulatus Linsley has been examined and compared with a rather extensive series of illinoiensis, and there seems to be no real difference between them. There is a considerable range of variation in illinoiensis, and punctulatus lies within this range.

GEOGRAPHIC RANGE.—Eastern, central, and south¬western United States.
HOSTS.—Calliopsis andrenijormis Smith and Hypo-macrotera callops callops Cockerell and Porter (un¬confirmed) and H. c. persimilis Cockerell (confirmed).

FEMALE.—Head and thorax black, clypcus apically rufotestaceous, metasoma red, though usually terga variably stained or darkened with black laterally and medially; antennae, tegulae, and legs usually dark reddish brown or deep mahogany red, mandibles rufotestaceous; calcaria reddish brown. Vestiture of body chiefly white, mostly closely apprcssed and form¬ing patches on face about antennal insertions, usually on hind margins of head, mesonotal line, dorsolateral angles of pronotum, mesoscutum circumferentially, mesepisterna, scutellum, metanotum, propodeum at sides, legs basally and on metasoma, especially on terga; dorsal surface of head, thorax, and metasoma sometimes with an intermixture of golden or reddish golden pubescence. Wings faintly violaceous, faintly brownish apically. Length 3.5-5 mm. Eyes bare or essentially so; face above antennae closely and rather finely punctate, neither bigibbosely swollen nor largely impunctate; antennae with first flagellar segment as long as or slightly longer than combined length of succeeding two segments; anterior and lateral ocelli separated by much less than twice their diameters; interocellar distance nearly equaling ocellorbital dis¬tance; rear angle of mandible situated much behind middle of eye; labrum feebly carinate longitudinally near base, without a thornlike tubercle basally, irreg¬ularly and variably punctate on basal half or more, usually with impunctate area mediobasally; ventral surface of head finely, though irregularly and sparsely, punctate adjacent to hypostomal carinae. Mesoscutum distinctly punctured, interspaces short and shining; scutellum entire or at most only weakly indented medially on posterior dorsal surface, not prominently bilobed, though moderately elevated posteriorly; metanotum produced posterolaterally into weakly developed posteriorly projected shelflike processes; mescpisternum densely and nearly rugosely punctate dorsally and with a variably developed patch or fringe of white pubescence; forewing with second submar-ginal cell not unusually small, one-half or more as long as first submarginal cell when measured along posterior side; spur of middle leg less than one-half as long as corresponding basitarsus. Mctasomal terga II-III basally with a transverse band of white pubescence on either side of middle; apical margin of tergum IV usually with a complete or nearly complete band of white pubescence; pygidial plate truncate apically; fifth mctasomal sternum with apical margin weakly incurved apically.

MALE.—Similar to female in coloration of integu¬ment and vestiture. Length 3.0-5.0 mm. Eyes bare; face as in female; antennae with first flagellar seg- ment longer than combined length of succeeding two segments; ocelli and rear angle of mandible situated as in female; labrum essentially as in female, perhaps less densely punctate basally; ventral surface of head, although generally rather irregularly punctate, more densely punctate than in female, interspaces polished and shining. Mesoscutum, scutellum, metanotum, mesepisternum and wings essentially as in female; tegulae impunctate and shining laterally. Metasomal terga II-VI basally with a transverse band of white pubescence on either side of middle; apical margins of terga IV and V usually with a complete transverse band of white pubescence; basin of metasoma rather sharply defined almost impunctate; apical margin of sixth metasomal tergum truncate, without a median triangular pro¬jection; seventh metasomal tergum with lateral margins, as seen from above, right angled on either side of pygidial plate; pygidial plate more than twice as long as maximum basal width, nearly parallel sided, narrowly liguliform in outline.
