HOST (unconfirmed).—Pseudopanurgus sp.


FEMALE.—Head and thorax black or at least dark in coloration, often pruinose on ventrally exposed surfaces, metasoma dark reddish brown, deep mahog¬any red, occasionally nearly entirely black with red¬dened tergal apices or rarely extensively reddish. though darkened or clouded with black medially, especially on apical terga; antennae, clypeus often apically, mandibles, pronotal tubercles usually and tegulae frequently reddish brown or rufotestaceous in coloration; legs usually dark reddish brown, often extensively marked or clouded with black; calcaria usually pale reddish brown. Vcstiture of body con¬spicuously white (though extensively and thickly inter¬mixed or supplanted with golden or reddish golden pubescence on dorsally exposed body surfaces), mostly closely appressed and forming white patches on face about antcnnal insertions, hind margins of head, dorsal surface of pronotum, mesonotal line, mesoscu-tum anteriorly, laterally and posteriorly, mesepisterna, scutcllum laterally, medially and posteriorly, and propodeum at sides; dorsal surfaces of vertex extending downward onto face, mesoscutum especially anteriorly and metasomal terga (adjacent to white pubescent patches) conspicuously and thickly clothed with golden or reddish golden pubescence. Wings feebly violaceous, somewhat darkened apically. Length 3.5-6 mm. Eyes bare or at most with a few, scattered, minute hairs; face above antennae rather closely and coarsely punctate, neither bigibbosely swollen nor largely impunctate; antennae with first flagellar seg¬ment conspicuously shorter than combined length of succeeding two segments; anterior and lateral ocelli separated by less than twice their diameters; intero-cellar distance shorter than ocellorbital distance; rear angle of mandible situated well behind middle of eye; labrum longitudinally carinate medially, without a thornlike tubercle near base, not closely punctate on basal half, with large impunctate or sparsely punctate shiny areas basally; ventral surface of head often with pruinose reflections in bright light, finely and irreg¬ularly punctate adjacent to hypostomal carinae, inter¬spaces variable in extent and shiny. Mesoscutum distinctly though closely and rather coarsely punctate throughout; scutellum usually deeply cleft medially to base, thus usually prominently bilobed, strongly elevated behind; mctanotum not produced postero-laterally into prominent, posteriorly projected shelflike processes; mescpisternum distinctly punctate, the punctures well separated, interspaces usually shining, with a large, conspicuous patch of white pubescence on vertical face; forewing with second submarginal cell not unusually small, more than one-half as long as first submarginal cell when measured along pos¬terior side; spur of middle leg about one-half as long as corresponding basitarsus. Metasomal terga II-IV basally with two discrete spots of white pubescence on either side of middle, dorsal surface of first metasomal tergum with a variably sized and shaped patch or divided patch of white (or yellowish white) pubes¬cence on either side of middle, sometimes covering much of dorsolateral surface and coalescing narrowly posteriorly, sometimes restricted in extent and nearly crescentic in shape, sometimes bipartite and some¬times expressed as a narrow longitudinal stripe; apical margin of tergum IV usually without white pubes¬cence. if present then expressed as an evanescent patch of white pubescence laterally on each side; pygidial plate rather broadly, almost truncately rounded; fifth metasomal sternum angularly incurved medially.

MALE.—Similar to female in coloration of integu¬ment and vestiture. Length 4-5 mm. Eyes, face, an¬tennae, ocelli, rear angle of mandibles, labrum, ventral surface of head essentially as in female. Mesoscutum, scutellum, metanotum, mesepisternum, and wings as in female; tegulae impunctate and shining laterally. Metasomal terga II-V (and usually VI) basally with two discrete spots of white (or yellowish) pubescence on either side of middle, dorsal surface of first meta¬somal tergum similarly variable and disposed as in female; apical margins of terga IV and V clothed or not as in female; basin of metasoma sharply defined, impunctate; apical margin of sixth metasomal tergum at most feebly bisinuatc in outline, without a mediantriangular projection; seventh metasomal tergum with lateral margins, as seen from above, evenly rounded, not angulately produced on either side of pygidial plate; pygidial plate more than twice as long as maxi¬mum basal width, nearly parallel sided, rather nar¬rowly liguliform in outline.
