Female. — Length 11 mm.; body black, mostly covered with bright 

 tawny or ochreous hairs; head with its facial line : transfacial 

 line :: 62 : 77, axial line : temporal line :: 31 : 19, malar line : joint 

 3 of antennae :: 15 : 9, ocelloccipital line : greatest diameter of lateral 

 ocellus :: 7 : 5, elevated portion of malar space nearly wanting, head 

 covered with tawny and black hairs, front longitudinally striate, 

 not elevated into a welt along the fovea, fovea at most : ocellocular 

 line :: 10 : 15, foveal band present and at upper end of the inner eye 

 margin : ocellocular line :: 1.5 : 15, distance between fovea and 

 ocelli : ocellocular line :: 6 : 15, fovea attenuated below its middle, 

 cuneiform and continued to a point well below the antennal line, 

 fovea filled with pale hairs along the inner eye margin and lower half, 

 and with very dark seal-brown hairs on the upper half, in addition 

 with some blackish hairs, fovarea wanting, vertex and temples along 

 the upper edge of the eye with black hairs, face dullish, finely indis- 

 stinctly reticulate, with indistinct punctures that are mostly as 

 many as four puncture widths apart, clypeus distinctly elevated 

 above the apical margin, slightly convex, nearly planate, sculptured 

 like the face except that the punctures are closer together, clypearea 

 barely represented by a median longitudinal shining streak, clypeus 

 thinly hairy its sculpture nearly hidden laterally by hairs, labrarea 

 truncate its width at base : length down the middle :: 9 : 5, width 

 at apex : length down the middle :: 5 : 5, labrarea at base nearly 

 half as wide as the labrum, the latter with a fringe of brownish hairs,

 + 5 :: 9 : 8, joint 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, antenna? blackish throughout, 

 mandibles typical, robust, extending a little beyond the outer edge 

 of the labrarea, black except for the apical third which is dark reddish, 

 palpi nearly typical; thorax covered with an abundance of tawny 

 hairs which are as long on the dorsulum where they are darker than 

 the almost ochreous hairs on the mesopleurae, dorsulum dullish,
