of mesonotum, with conspicuous white tufts of pubescence 
around tubercles and behind wings; mesonotum with scattered 
punctures medially, closely punctured anteriorly and laterally, 
tessellate between the punctures; scutellum more finely and 
closely punctate; pleura closely punctate, shining, with long thin 
white hair; propodeum tessellate, with scattered fine punctures, 
closer laterally, basal triangle tessellate but impunctate; tegulae 
dark ferruginous, minutely punctate, with a small tuft of white 
hair anteriorly; wings hyaline basally, dusky apically, the second 
recurrent nervure entering the second submarginal cell somewhat 
nearer the apex than the first does to the base; basal nervure 
beyond transverse median; nervures piceous to ferruginous; legs 
black, white pubescent, femora shining, sparsely punctate, outer 
faces of tibiae strongly punctate, all the tibiae ferruginous at apex; 
tarsi black, the middle and hind tarsi as broad as their tibiae, the 
middle ones densely pubescent, all the tarsi yellowish pubescent 
beneath; spurs yellowish-ferruginous; claws ferruginous basally,. 
darker apically, without a distinct basal tooth. 
Abdomen rather broad, ovoid, segments 3-5 strongly de- 
pressed on the apical margin, but not so strongly as in the male, 
with very deep transverse basal grooves, the anterior borders of 
which are sharpty carinate, these carinate margins overlapping 
the grooves; discs of segments shining, punctures strong but 
well separated, finer and closer on basal segments, the portions 
of the discs basad of the grooves finely tessellated and very 
finely punctured; segment 6 obtusely triangular viewed from 
above, straight in profile, with a median longitudinal ridge, 
rather coarsely rugoso-punctate with appressed white pubescence, 
tinged with brown apically, and a few black hairs at the sides 
basally; the other dorsal segments are apparently white fasciate 
(specimen somewhat rubbed), the fasciae entire on apical seg- 
ments, very fine on basal segment, but tufted at sides; all the 
segments except the first with rather course black hairs on the 
discs laterally, which disappear dorsally; scopa white, black on 
segment 6, and with a few black hairs apically on sides of segment 
5. Length 13 mm.
