subapical tooth, blackish, becoming ferruginous apically; antennae black basally, flagellum becoming obscurely brownish-piceous apically, basal segment somewhat broader than
long, following segments longer, the more
median segments being slightly longer than
broad; lateral ocelli somewhat nearer each
other than to eyes; face below ocelli somewhat
shining between coarse, deep, distinct and
rather close punctures, these becoming somewhat more shallow, sparse and vague below,
supraclypeal area only slightly elevated, quite
closely but rather shallowly punctate, clypeus
dull, punctures quite coarse but shallow, close
in general; verbx skining between eyes and
ocelli, punctures becoming rather fine and
sparse, hind margin rather coarsely and irregularly rugoso-striate, cheeks above dull, rugo- so punctate, becoming somewhat smoother on lower surface, with a few obscure, shallow but
rather coarse punctures; wings lightly infuscated, with the usual three submarginal cells,
veins and stigma brownish; tegulae piceous;
legs black, becoming more brownish-testaceous
at tips of tarsi; scutum and scutellum shining, punctures deep and distinct, not very
coarse, widely separated over most of scutum,
being rather sparse between notaulices and
tegulae, and well separated along anterior
margin, scutellum with irregular and rather
sparse punctures, these being somewhat closer
around margin; pleura coarsely reticulate;
dorsal area of propodeum very coarsely rugoso-striate, lateral faces dull, finely rugose an- teriorly, becoming more reticulate posteriorly,
posterior face reticulate; abdominal terga
smooth and shining, basal tergum practically
impunctate, with only a few, widely scattered,
minute punctures at extreme sides, those on tergum 2 very fine and rather close across
narrow, basal area, becoming more generally
distributed but very sparse towards sides,
those on 3 somewhat deeper and more distinct, covering a large part of the disc but
becoming sparse apically, apical margins of all terga broadly impressed and impunctate,
