MALE—Length 8 mm.; lateral ocelli very slightly nearer margin of vertex than to each other; cheeks subequal to eyes in width, posterior margin subcarinate; antennal scape quite strongly swollen, apex deeply excavated, partially enclosing pedicel, longer side of basal segment of flagellum equal to segment 2, median segments very slightly longer than broad; mandibles slender and simple apically; wings hyaline, only the rather narrow apical margin and marginal cell lightly infuscated, with the usual three submarginal cells, 2nd and 3rd subequal anteriorly, veins and stigma testaceous, basal vein much basad of transverse median; tegulae shining between rather fine punctures, these close over anterior half, becoming sparse posteriorly; posterior margin scutellum quite deeply depressed medially; front coxae not spinose; hind femora slender and simple; lower half of face largely yellow, but broadly black laterad of bases of antennae and reaching the supraclypeal area, the lateral facial maculations extending very narrowly top of eye, and cheeks very narrowly yellow along posterior orbits nearly to top; vertex, cheeks and upper part of face black; antennal scape bright yellow anteriorly, piceous posteriorly, flagellum more reddish-testaceous; thorax largely black, with only the tubercles and a small anterior maculation on mesopeura, yellow; coxae black in large part, becoming yellowish apically, trochanters more testaceous; front and mid femora testaceous posteriorly, yellowish anteriorly, the tibiae largely yellow with some testaceous infusions, and tarsi entirely yellow; hind femora piceous posteriorly, more testaceous anteriorly, apex yellow, hind tibiae yellow at base, otherwise more testaceous, and tarsi testaceous; spurs pale yellow; abdominal terga 2 and 3 with broad, transverse, submedian, yellow bands that are somewhat narrowed medially, 4-6 with more apical, yellow bands separated from apical rims only by the impressed apical margin; tergum 1 with a pair of transverse, more lateral maculations that are slightly separated medially by a testaceous zone, 1-3 piceous basally and apically, 4-6 becoming more brownish or testaceous apically; discs of abdominal sterna 2-6 largely yellow, the impressed apical areas more testaceous, becoming yellowishhyaline along the rims; sternum 1 with a very small, median, yellow spot; vertex and face above antennae quite coarsely rugose, cheeks becoming somewhat more finely rugoso-punctate, lower part of face more distinctly but finely punctate, the supraclypeal area and clypeus with minute, close and very vague punctures; scutum and scutellum densely rugose, mesopleura somewhat more coarsely rugoso-punctate; propodeum posteriorly more shallowly rugoso-punctate, lateral faces becoming rather smooth below and along margin of metapleura; punctures of abdominal terga 2-6 very fine and close, becoming somewhat more distinctly separated apically, especially on the more apical terga, very minute medially on basal tergum, becoming impunctate laterally and basally; pubescence entirely pale, quite copious over head and thorax but not hiding surface, very fine, short and obscure on abdominal terga, but the more apical hairs becoming more elongate; sternal plates with more elongate, sparse, fine hairs, these becoming rather dense on apex of sternum 6; median length of pygidial plate about equal to basal width, somewhat narrowed apically, apex rather deeply incised, margins strongly carinate, surface rather closely and shallowly punctate; exposed sternal plates unmodified, sternum 6 strongly narrowed apically, sub- triangular; sternum 8 with a slender apical process; gonocoxites of genital armature much as in denticulata (fig. 107).
