fovea, fovea at most : ocellocular line :: 10: 14, foveal band virtually wanting 
at upper end of the inner eye margin, distance between fovea and ocelli : ocel- 
locular line :: 4: 14, fovea hardly attenuated below its middle where it is ap- 
parently nearly as wide as the greatest width of the fovea, the latter continued 
to a point apparently half-way between the clypeal line and the antennal line, 
fovea with the upper two-thirds filled with pale cocoa brown hairs, the lower 
third with white hairs, vertex and temples along the upper edge of the ey# with 
brownish or black hairs, face mostly shiny, partly indistinctly reticulate, with 
shallow punctures that are from adjoining to as many as three puncture widths 
apart, foveaewith some long brownish hairs, clypeus slightly elevated above the 
apical margin, convex, sculptured like the face except that the surface is some- 
what rippled and the punctures are more pit-like and not adjoining but from 
one to two puncture widths apart, clypearea w'anting, clypeus thinly hairy, its 
sculpture not at all hidden by hairs, labrarea emarginate, its width at base : 
length down the middle : : 1 1 : 6, width at apex : length down the middle ; : 3 : 6, 
greatest length : length down the middle : : 7 : 6, labrarea at base nearly half as 
wide as the labrum, basal half of labrarea with sloping sides, apical half with 
parallel sides, labrum with a fringe of golden hairs, labrum without structure 
or definite sculpture between the labrarea and apical edge of labrum, joint 3 
of antennae : 4 + 5 :: 10: 8, joints 4 and 5 thicker than long, the succeeding 
joints as thick as long or little longer than thick, except joint 12 which is dis- 
tinctly longer than thick, antennae blackish throughout, mandibles typical, 
robust, extending beyond the outer edge of the labrum, black except for the 
apical half which is mostly dark reddish, palpi typical; thorax covered wdth 
an abundance of pale whitish hairs which are nearly as long on the dorsulum 
where they are darker than the almost white hairs on the mesopleura, dorsulum 
dullish, coarsely reticulated, notauli represented by a shining fine, mesopleura 
sculptured like the dorsulum but more coarsely, scutel hairy and sculptured 
much like the dorsulum, metanotum hairy and sculptured like the dorsulum 
except that the sculpture is denser and less distinct, tegulae dark brown, 
polished, wing base partly blackish brovTi, subcosta blackish brown, stigma 
dark brown, rest of veins dull stramineous, with a blackish tinge, first recurrent 
vein received by the second submarginal cell a little farther from the first trans- 
verse cubitus than the first transverse cubitus is long, nervulus not inter- 
stitial, received by the median cell and forming an acute angle with the second 
abscissa of the median vein, membrane uniformly tinged with brown, legs 
brownish or blackish brown, covered with brownish golden and whitish hairs, 
scopa nearly typical, loose, its hairs of the lower two-thirds whitish, almost white, 
of its upper third with a brownish hue, hairs at base above decidedly darkened, 
hind metatarsi at most apparently a little narrower than mid metatarsi; 
propodeum with its enclosure poorly defined, shiny and sculptured by means 
of crooked rugae and a median longitudinal carina, rest of upper face of pro- 
podeum sculptured somewhat like the dorsulum but with smaller meshes, and 
covered with nearly white hair propodeal pleura with sparse shallow punc- 
tures, finely reticulate and not hidden by the almost white floccus; abdomen 
with its tergum shiny except the dullish tergite, punctured and finely reticu- 
lated, the punctures from two to four puncture widths apart on the first tergite
