LOCATION OF TYPES.—H. elegans and H. knulli, Ohio State University, Columbus; H. stevensi, Na¬tional Museum of Natural History, Washington, D.C.
GEOGRAPHIC RANGE.—Southern Canada (Alberta), north-central (North Dakota and Nebraska) and southwestern United States (Arizona, New Mexico, and Texas).
HOSTS.—Calliopsis crypta Shinn (confirmed) and possibly C. rozeni Shinn.

FEMALE.—Head and thorax black, metasoma red or chiefly so, sometimes terga darkened medially; antennae, tcgulae, and legs usually dark reddish or deep mahogany brown, mandibles and anterior mar¬gin of clypcus bright rufotestaceous; calcaria reddish brown. Vestiture of body chiefly white, mostly closely appressed and forming patches on face about antennal insertions, hind margins of head usually, mesonotal line, dorsolateral angles of pronotum, anterolateral angles of mcsoscutum, mesepisternum, scutcllum inwhole or in part, metanotum and propodeum norm¬ally at sides, legs basally and on metasoma, especially on terga; dorsal surfaces of head, thorax and metasoma without or at most only very inconspicuously clothed with a few intermixed golden or reddish golden hairs. Wings feebly violaceous, faintly tinged with brownish apically. Length 4-7.5 mm. Eyes bare or at most with a few, scattered, short hairs; face above antennae closely and coarsely punctate, neither bigibbosely swollen nor largely impunctate; antennae with first flagellar segment shorter than succeeding two seg¬ments; anterior and lateral ocelli separated by much less than twice their diameters; interocellar and ocellorbital distances about equal; rear angle of man¬dible well behind middle of eye; labrum longitudinally carinate medially, without a thornlike tubercle near base, rather closely punctate on basal half or more ex¬cept impunctate mediolongitudinally; ventral surface of head rather closely and coarsely punctate adjacent to hypostomal carinae, interspaces less than puncture width across. Mesoscutum rather coarsely and nearly rugosopunctate throughout; scutellum entire or at most only weakly indented medially on posterior dorsal surface, not prominently bilobed and not strongly elevated posteriorly; metanotum produced posterolat-erally into prominent posteriorly projected shelflike processes; mesepisternum rather coarsely and nearly rugosely punctate dorsally and with a large ringlike patch of white pubescence; wing with second submar-ginal cell not usually small, more than one-half as long as first submarginal cell when measured along posterior side; spur of middle leg less than one-half as long as corresponding basitarsus. Metasomal terga II-IV basally with a transverse band of white pu¬bescence on either side of middle, rarely bands greatly reduced to form a spot (as in elegans type of varia¬tion) ; apical margin of tergum IV usually with a quadripartite band of white pubescence, shortest band segments situated laterally, widest band segments situated immediately on either side of middle (occa¬sionally absent in some specimens) ; pygidial plate truncate apically, rounded laterally; fifth metasomal sternum with apical margin entire or only slightly incurved medially.

MALE.—Similar to female in coloration of integu¬ment and vestiture. Length 4-7 mm. Eyes bare or at most with a few scattered hairs, not densely hirsute; face as in female; antennae with first flagellar segment much less than combined length of succeeding two segments; ocelli and rear angle of mandible as in female; labrum essentially as in female; ventral sur¬face of head punctate about as in female. Mesoscutum, scutellum, metanotum, mesepisterna, and wings as in females; tegulae very nearly punctate throughout. Metasomal terga II-V basally with a transverse band of white pubescence on either side of middle (rarely bands reduced to form a spot) ; apical margin of tergum IV with only a short band or spot of white pubescence laterally; apical margin of tergum V (and sometimes VI also) with a complete (rarely in¬terrupted medially) transverse band of white pu¬bescence; basin of metasoma not sharply defined, punctured at least at sides; apical margin of sixth metasomal tergum feebly bisinuate in outline, without 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 more than twice as long as maximum basal width, nearly parallel sided essentially liguliform in outline.
