Female. — Length 8 mm.; body black, mostly covered with pale 

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

 line :: 59 : 63, axial line : temporal line :: 28 : 16, malar line : joint 

 3 of antenna :: 2 : 9, ocelloccipital line : greatest diameter of lateral 

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

 covered with hairs that are concolorous with the body hairs, front 

 rather distinctly, longitudinally striate, frontal crista vestigeal,. 

 front not elevated into a welt along the fovea, fovea at most : ocellocu- 

 lar line :: 7.5 : 11, foveal band represented by a shiny line at upper 

 end of the inner eye margin, distance between fovea and ocelli : 

 ocellocular line :: 4 : 11, fovea somewhat attenuated below its 

 middle where it is apparently only a little narrower than the greatest 

 width of the fovea, the latter continued to a point apparently a little 

 above the clypeal line, fovea filled with hairs that are concolorous 

 with the body hairs, vertex and temples along the upper edge of the 

 eye with the hairs concolorous with the body hairs, face polished with 

 distinct punctures that are from adjoining to as many as three punc- 

 ture widths apart, clypeus slightly elevated above the apical margin, 

 convex, sculptured like the face except that the punctures are larger 

 and mostly not so close together, clypearea present but poorly 

 defined, clypeus thinly hairy its sculpture not at all hidden by hairs,, 

 labrarea emarginate, its width at base : length down the middle :: 

 12 : 4, width at apex : length down the middle : 3.5 : 4, labrarea 

 at base nearly two-thirds as wide as the greatest length of labrum, 

 the latter with a fringe of pale hairs, labrum without a median 

 longitudinal crista between the labrarea and apical edge of labrum,. 

 joint 3 of antennse : 4 + 5 :: 9 : 9, joint 4 thicker than long, the 

 succeeding joints as thick as long or a little longer than thick except 

 joint 12 which is distinctly longer than thick, antenna? blackish brown 

 throughout, mandibles typical, robust, extending to the outer edge 

 of the labrarea, black except for the apical half which is mostly clear
