with fine whitish hair, propodeal pleura partly impunctate, mostly with 
sparse indefinite shallow punctures, propodeal floccus thin and pale ochreous; 
abdomen with its tergum shiny and sculptured much like the temples except 
that the first and second tergites are nearly polished, the punctures mostly 
from three to eight puncture widths apart on the first tergite, the punctures 
closer together on the succeeding tergites, second, third, and fourth tergites 
with a thin, whitish apical hair band that is interrupted in the middle of the 
second and third, apical edge of second, third, and fourth tergites with a stram- 
ineous border, second tergite with its elevated portion down the middle : de- 
pressed portion :: 17:10, fifth tergite shiny, reticulate, its punctures closer 
together than on the other tergites, pygidium nearly planate, with an embossed 
central area, nearly pointed at apex, tergum with inconspicuous, pale, appressed 
hairs in addition to the hair bands, fimbria pale brownish golden.

lemon yellow hairs, head with its facial line : transfacial line :: 48: 61, axial 
line : temporal line :: 27: 17, malar line : joint 3 of antennae :: 1.5 : 8, ocelloc-

malar space nearly wanting, front rather distinctly, longitudinally striate, not 
elevated into a welt along the fovea, with a rather distinct median longitudinal 
crista, fovea at most : ocellocular line :: 7.5: 11, foveal band represented by a 
shining line and a nearly bare beveled area the width of which : ocellocular 
line :: 1: 11, distance betwedn fovea and oceUi : ocellocular line :: 4: 11, fovea 
somewhat attenuated below its middle where it is apparently only a httle 
narrower than the greatest width of the fovea, the latter continued to a point 
apparently a little below the antennal line, fovea filled with hairs that are con- 
colorous with the hairs of the body, vertex and temples along the upper edge 
of the eye with hairs that are concolorous with the body hairs, face mostly 
polished, with indistinct punctures of two sizes which are as many as five or more 
puncture widths apart, clypeus slightly elevated above the apical margin, 
slightly convex, sculptured hke the face except that the punctures are larger, 
sparser and better defined, clypearea present, polished, well defined, and on the 
lower half nearly half as wide as the labrarea, clypeus thinly hairy, its sculpture 
not at all hidden by hairs, labrarea emarginate, its width at base : length down 
the middle :: 8:4, width at apex : length down the middle :: 6:4, greatest
