SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION
by Linsley
LOCATION OF TYPE.—California Academy of Sci¬ences, San Francisco.
GEOGRAPHIC RANGE.—Southwestern United States (Arizona and New Mexico).
HOSTS (unconfirmed).—Pseudopanurgus boylei (Cockerell), P. perlaevis (Gockerell), P. timberlakei Cockerell, Pseudopanurgus species B, and Pseudo¬panurgus spp.
FEMALE.—Head and thorax black, metasoma red or chiefly so, sometimes terminal terga darkened or clouded medially; antennae, mandibles, tegulae, and legs reddish or dark mahogany brown; calcaria dark reddish brown. Vestiture of body chiefly white, mostly closely appressed and forming patches on face adja¬cent to antennal insertions, head behind, mesonotal line, dorsolateral angles of pronotum, anterolateral margins and sides of mesoscutum, mesepisterna, scutel-lum at sides, medially and behind, metanotum and propodeum especially laterally, legs basally and on metasoma not conspicuously clothed with golden or reddish golden pubescence. Wings feebly violaceous, lightly tinged with brownish beyond closed cells. Length 4—8 mm. Eyes densely clothed with short, erect pubescence; face above antennae somewhat swollen, polished, shining, largely impunctate; anten¬nae with first flagellar segment longer than combined length of succeeding two segments; anterior and lat¬eral ocelli separated by at least three times their diameter; interocellar distance greater than ocellorbi-tal distance; rear angle of mandible situated well beyond middle of eye; labium longitudinally carinate medially, without a thornlike tubercle near base, densely and closely punctate on basal half or more, without impunctate areas basally; ventral surface of head rather sparsely punctate especially adjacent to hypostomal carinae, interspaces polished and shining. Mesoscutum very coarsely and somewhat rugosopunc-tate throughout; scutellum entire or feebly indented medially on posterior dorsal surface, not prominently bilobed and strongly elevated posteriorly; metanotum produced posterolateral^ into prominent posteriorly projected shelflike processes; mesepistemum rather coarsely and nearly rugosely punctate and with a large ringlike patch of white pubescence; wing with second submarginal cell not unusually small, more than one-half as long as first submarginal cell when measured along posterior side; spur of middle leg about one-half as long as corresponding basitarsus. Metasomal terga II-III basally (usually also succeed¬ing terga) with two discrete spots (sometimes evanes¬cent) of white pubescence on either side of middle; apical margin of tergum IV with at most a spot or short band of white pubescence laterally; pygidial plate truncate or nearly so, rounded laterally; fifth metasomal sternum with apical margin incurved medi¬ally, not strongly emarginate.
MALE.—Similar to female in coloration of integu¬ment and vestiture. Length 3.5-8 mm. Eyes as densely hairy as in female; face as in female; antennae with first flagellar segment shorter than combined length of succeeding two segments; interocellar and ocellorbi-tal distances about equal; rear angle of mandible situated as in female; labrum essentially as in female; ventral surface of head somewhat more densely and closely punctured than in female. Mesoscutum, scutel¬lum, metanotum, mesepistemum, and wings as in female; tegulae sparsely punctate laterally, shining. Metasomal terga II-VI basally with two discrete spots (sometimes lacking or evanescent) of white pubes¬cence on either side of middle; apical margin of tergum IV with only a short band or spot of white pubescence laterally; apical margin of tergum V with at most only a spot of white pubescence laterally; basin of metasoma not sharply defined, punctured at least at sides; apical margin of sixth metasomal tergum feebly bisinuate in outline, with at most an obsolescent 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 maxi¬mum basal width, liguliform in outline.
