and set off by a rim to each puncture, the punctures closer on the succeed- 
ing tergites and not rimmed, second, third and fourth tergites without hair 
bands, apical edge of first, second, third and fourth tergites with a brownish 
stramineous border, second tergite with its elevated portion dowm the middle : 
depressed portion :: 17:9, fifth tergite indistinctly reticulate, its punctures 
more distinct than on the other tergites, pygidium black, nearly planate, nearly 
truncate at apex, tergum with inconspicuous, nearly erect, whitish hairs, fim- 
bria brownish.

Female. — Length 1.5 mm.; body black, mostly covered with pale ochreous 
and almost white hairs; head with its facial line : transfacial line :: 73: 96, 
axial line : temporal line :: 40:26, malar line : joint 3 of antennae :: 3:12, 
elevated portion of malar space virtually wanting, ocelloccipital line : greatest 
diameter of lateral ocellus :: 8: 5, head covered with whitish hairs, front striato- 
punctate, not elevated into a welt along the fovea, fovea at most : ocellocular 
line :: 13: 19, foveal band present and at upper end of the inner eye margin : 
ocellocular line :: 2: 19, distance between fovea and ocelli : ocellocular line :: 
4: 19, fovea attenuated below its middle where it is apparently only a little 
narrower than the greatest width of the fovea, the latter continued to a plane 
apparently a little below the antennal line, fovea filled with very pale ochreous, 
almost wliite, hairs, fovarea wanting, face mostly polished or almost polished, 
partly mdistinctly reticulate, with shallow ill-defined punctures that are mostly 
from adjoining to two puncture widths apart, clypeus distinctly elevated above 
the apical margin, convex, with better defined punctures than on the face, the 
pmictures mostly from one to two puncture widths apart, clypearea barely 
indicated, clypeus thickly hairy on each side of the clj^jearea, its sculpture 
almost hidden by the hairs, labrarea deeply almost triangularly emarginate, 
its width at base : its greatest length :: 15: 5, distance between lower corners : 
length dot'll the middle :: 4.5: 3, distance between lower corners of cLticus : 
width of labrarea at base :: 25: 15, labrum with a fringe of pale golden hairs, 
labrum apparently without a median longitudinal crista between the labrarea 
and apical edge of labrum, joint 3 of antennae : 44-5 :: 12: 9, joints 4 and 5 
thicker than long, the succeeding joints from a little thicker than long to a 
little longer than thick except joint 12 which is distinctly longer than thick, 
antennae blackish to castaneous throughout, mandibles typical, robust, ex- 
tending to beyond lower corners of the clypeus, dark castaneous except for a 
subapical blackish stain, palpi nearly typical; thorax covered with an abun- 
dance of whitish hairs, except on the dorsulum where the hairs are dark ochre- 
ous or nearly fulvous, the hairs on the dorsulum so densely plumose and close 
together as to conceal the sculpture, and apparently not more than one-third 
as long as the whitish hairs on the mesopleura, dorsulum where denuded.
