down the middle ajjparently shorter than the depressed portion, head mostly 
covered with pale ochreous hairs, front rather indefinitely reticulato-rugulose, 
not elevated into a welt along the fovea but divided down the middle by a longi- 
tudinal Carina, fovea at most : ocellocular line :: 15: 17, foveal band virtually 
wanting at ujjper end of the inner eye margin, distance between fovea and 
ocelli: ocellocular line :: 2: 17, fovea somewhat attenuated below its middle 
where it is ai)parently only a little more than half as wide as the greatest width 
of the fovea, the latter continued to a plane apparently a little below' the clypeal 
line, fovea filled with pale ochreous hairs, fovarea wanting, vertex and front 
wdth pale ochreous hairs, rest of head wdth whitish hairs, face mostly shiny, 
partly dullish, finely reticulate, with shallow' punctures that are mostly from 
adjoining to three puncture wddths apart, clypeus distinctly elevated above the 
apical margin, convex, shiny, finely reticulated, more deeply punctured than the 
face, the jiunctures mostly from one to two puncture wddths apart, clypearea 
represented by a slight elevation down the middle and greater interstices 
between the inmctures down the middle, clypeus thinly hairy, its sculpture not 
at all hidden by hairs, labrarea subemarginate, its wddth at base: length dowm 
the middle :: 17: 5, width at apex : length down the middle :: 8:5, greatest 
length of labrarea slightly in excess of the length down the middle, labrarea at 
base : distance between lower corners of clypeus : : 1 7 : 29, with a fringe of golden 
hairs, but without a median longitudinal crista between the labrarea and apical 
edge of labrum, joint 3 of antennae : 4-|-5 :: 17: 14, joint 4 a little thicker than 
long, the succeeding joints from nearly as thick as long to three-fourths as thick 
as long, excej)t joint 12 which is at least twnce as long as thick, antennae black- 
ish except the under side of the flagel which is blackish browm, mandibles 
typical, robust, extending to the low'er corners of the clypeus, black except for 
most of the apical half wdiich is dark reddish, palpi nearly typical; thorax 
thinly hairy, the hairs on the dorsulum pale ochreous or golden and shorter than 
the whitish hairs on the mesopleura, dorsulum partly dullish, partly shiny, 
finely reticulated and punctured mu?h like the clypeus but not so deeply 
punctured, notauli represented by a dullish line, mesopleura almost ruguloso- 
punctate and finely reticulate, more closely punctured than the dorsulum, 
scutel nearly polished, metanotum hairy and densely sculptured, indistinctly 
punctured and dullish, tegulae browmish stramineous, nearly polished, blackish 
browm at base, wnng base partly blackish brown, partly stramineous, subcosta 
blackish brown, stigma brownish stramineous, rest of veins concolorous wdth 
the stigma, first recurrent vein received by the second submarginal cell beyond 
the middle and nearly as near to the second transverse cubitus as the first 
transverse cubitus is to the stigma on the radial vein, nervulus interstitial 
and forming an acute angle wdth the first abscissa of the discoidal vein, mem- 
brane with a deep browm stain, legs blackish browm except for the small joints 
of the tarsi w'hich are more or less browmish, legs covered with w'hitish, golden, 
and browmish hairs, scopa typical, its hairs of the lowmr half almost w'hite, of 
its upper half wdth a pale golden hue, hairs at base above decidedly darkened, 
hind metatarsi at most : greatest width of mid metatarsi : : 1 1 : 1 1 ; propodeum
