its sculpture not at all hidden by hairs, labrarea rounded, nearly semicircular in 
outline, its width at base : length down the middle :: 9:3, labrarea at base; 
distance between lower clypeal corners as 9: 14, labrum with a thin fringe of 
golden hairs, labrum apparently without a median longitudinal crista between 
its apical edge and the lal)rarea, joint 3 of antennae : 4+5 :: 4: 0, joints 4 and 
5 thicker than long, the succeeding joints as thick as long or a little longer than 
thick except joints 11 and 12 which are distinctly longer than thick, antennae 
from pale to blackish brown, paler beneath than above, mandibles typical, 
robust, extending to a little beyond the outer edge of the labrarea, dark reddish 
except for the basal third which is partly blackish, palpi nearly typical, greatest 
thickness of 2nd joint of maxillary palpi ; length of the same joint :: 1:3.5; 
thorax covered with an abundance of pale ochreous, almost white hairs which 
are as long on the dorsulum as the hairs on the mesopleura, dorsulum shiny, 
finely reticulated and punctured like the face but more distinctly so, notauli 
represented by a faint shiny line, mesopleura sculptured somewhat like the 
dorsulum but not so closely punctured, scutel hairy and nearly polished, its 
punctures spaced as on the dorsulum, the punctures however smaller and more 
sharply defined, metanotum hairy and sculptured like the dorsulum except 
that the sculpture is denser and less distinct, tegulae pale stramineous, partly 
polished, wing base dull stramineous, subcosta bro^\Tiish, stigma pale stramin- 
eous, its lower margin brownish, rest of veins dull stramineous, with a black- 
ish tinge, first recurrent vein received by the second submarginal cell beyond 
the middle and nearly twice as far from the second transverse cubitus as the 
first transverse cubitus is from the stigma on the radial vein, nervulus received 
by the median cell and forming an acute angle with the second abscissa of the 
median vein, membrane uniformly vuth a pale stramineous tinge, legs browm- 
ish except for the tarsi which are more or less pale stramineous, legs covered 
with pale ochreous and whitish hairs, scopa atypical, its hairs sparse, loosely 
arranged and whitish except at base above where they are golden, hind metatarsi 
apparently a little wider than middle metatarsi; propodeum with its enclosure 
poorly defined, shiny and finely reticulated, except for a network of coarse 
rugae, rest of upper face of propodeum sculptured somewhat like the enclosure 
but with a much finer network of carinae, and with fine pale ochreous hair, 
propodeal pleura finely reticulate and with sparse shallow punctures not almost 
hidden by the whitish floccus; abdomen with its tergum shiny and sculptured 
much like the metapleura, the punctures of the first tergite so sparse and in- 
distinct as to appear wanting, the punctures hardly more evident on the suc- 
ceeding tergites, second, third, and fourth tergites with a thin, apical, fringe 
of pale ochreous hair, not appearing banded, apical edge of first, second, third, 
and fourth tergites stramineous, second tergite with its elevated jrortion down 
the middle ; depressed portion 10: 6, fifth tergite shiny, reticulate, its punc- 
tures closer together and more distinct than on the other tergites, pygidium 
nearly planate, with a shallow furrow on each side, truncate at apex, tergum 
with inconspicuous, pale appressed hairs in addition to the fringes, fimbria 
pale golden with a faint brownish tinge.
