MALE—Length 5-6 mm.; head, thorax and legs black, antennae somewhat reddened beneath apically, mandibles reddish, and labrum becoming testaceous apically; tegulae yellowish-hyaline or piceous, wings subhyaline, veins brownish to piceous; mid and hind tibial spurs pale yellow; abdominal terga more or less ferruginous (varying from light testaceous to deep brick red); cheeks slightly narrower than eyes; clypeus very slightly protuberant, its median length about one-third the distance between eyes; eyes subparallel; mandibles slender and simple; labrum much as in female; basal segment of flagellum equal to segments 2 plus 3 in length; seutum slightly sulcate medially toward anterior margin; posterior margin of scutellum very slightly impressed medially; puncturation much as in female, median length of pygidial plate only very slightly longer than basal width, the margins carinate, parallel, apex broadly rounded; pubescence as in female; sternum 7 more truncate apically than illinoiensis (fig.
114); and sternum 8 more elongate; genital armature closely resembling that in iflinoiensis, but tips of gonocoxites somewhat reflexed.
DISTRIBUTION—Minnesota to Michigan, south to Tennessee, June to August

Geographic Range Notheatern, centrail and southwestern United States and Mexico
Hosts: Callioppis andreniformis and possable Psuedoanurgus
FEMALE.—Head and thorax black, clypeus apically rufotestaceous metasoma red, orange, yellow, or black, usually with at least some red, orange, or yellow later¬ally and apically, though sometimes extensively and nearly entirely black or brownish black; antennae, tegulae, and legs usually reddish brown or deep mahogany red; mandibles extensively rufotestaceous; calcaria pale reddish brown. Vestiture of body chiefly white, mostly closely appressed and forming patches on face about antennal insertions, usually on hind mar¬gins of head, mesonotal line, dorsolateral surfaces of pronotum, mesoscutum circumferentially, mesepisterna, scutellum at sides and medioapically, metanotum, pro-podeum at sides, legs basally and on metasoma, especi¬ally on terga; dorsal surfaces of head, thorax, and metasoma without golden or reddish golden pubes¬cence. Wings faintly violaceous, feebly infuscated apically. Length 4-6 mm. Eyes bare or at most with a few, scattered, minute hairs; face above antennae closely and rather coarsely punctate, neither bigibbose-ly swollen nor largely impunctate; antennae with first flagellar segment equaling combined length of succeed¬ing two segments; anterior and lateral ocelli separated by much less than twice their diameters ;interocellar dis¬tance slighdy less than ocellorbital distance; rear angle of mandible situated near middle of eye; labrum at most obsolescently carinate longitudinally, without a thornlike tubercle basally, irregularly and variably punctate on basal half or more, usually impunctate mediolongitudinally; ventral surface of head finely, though irregularly and sparsely, punctate adjacent to hypostomal carinae. Mesoscutum coarsely and closely punctate, very nearly rugosopunctate throughout; scutellum entire or at most only weakly indented medially on posterior dorsal surface, not prominently bilobed though moderately elevated posteriorly; meta¬notum produced posterolaterally into well-developed posteriorly projected shelflike processes; mesepister-num densely and nearly rugosely punctate dorsally and with an irregularly and variably developed ring¬like patch of white pubescence; forewing with second submarginal cell not unusually small, one-half or more as long as first submarginal cell when measured along posterior side; spur of middle leg nearly one-half as long as corresponding basitarsus. Metasomal terga II-IV basally with two discrete spots of white pubes¬cence on either side of middle, dorsal surface of first metasomal tergum usually with a large irregular patch of white pubescence on either side of middle; apical margin of tergum IV with four nearly equidistant small spots of white pubescence; pygidial plate api¬cally rounded; fifth metasomal sternum entire or at most only weakly incurved medially.
MALE.—Similar to female in coloration of integu¬ment and vestiture. Length 3.5-6 mm. Eyes bare or at most with a few, scattered, minute hairs; face as in female; antennae with first flagellar segment longer than combined length of succeeding two segments; ocelli and rear angle of mandible situated as in fe¬male; labrum as in female; ventral surface of head somewhat more closely punctate than in female, but with large polished and shining interspaces. Meso¬scutum, scutellum, metanotum, mesepisternum, and wings as in female; tegulae punctate throughout. Metasomal terga II-VI basally with two discrete spots of white pubescence on either side of middle, dorsal surface of first metasomal tergum with an irregular patch of white pubescence on either side of middle; apical margin of tergum IV with a short band of white pubescence laterally; apical margin of tergum V with four nearly equidistant short bands or spots of white pubescence; basin of metasoma not sharply de¬fined, punctured at least laterally; apical margin of sixth metasomal tergum neither bisinuate in outline nor with a median triangular projection; seventh metasomal tergum with lateral margins, as seen from above, nearly right angled on either side of pygidial plate; pygidial plate less than twice as long as maximum basal width, rather broadly liguliform in outline. This species, which is one of the more easily dis¬tinguishable species of the subgenus Holcopasites, is the most wide-ranging species of the genus. There is a good deal of variation in the coloration of the meta-soma; however, on the basis of colorational features of the metasomal terga two geographically segregable subspecies are recognizable.
