 is mostly whitish, the only dark or blackish hairs are sparsely scattered 

 along the inner and lower edge of the foveae, front longitudinally 

 striate throughout except laterally on the lower half where it is 

 reticulate and rather indefinitely punctured, fovea whitish except 

 for a few erect dark hairs, at most almost exactly two-thirds as wide 

 as the ocellocular line is long, attenuated below and reaching dis- 

 tinctly below the antennal line but not to the clypeal line, facial 

 line : transfacial line :: 50 : 61, axial line : temporal line :: 26 : 16, 

 joint 3 of antennae : joints 4 + 5 :: 7 : 6, joints 4-8 inclusive 

 apparently thicker than long, the remaining joints not much longer 

 than thick, antennae blackish except that beyond the fourth joint 

 they are brownish beneath, antennae dullish, end joint typical,, 

 clypeus convex, with adjoining and nearly adjoining punctures, 

 clypeus appearing black, covered with sparse whitish hairs, clypearea 

 wanting, labrarea nearly twice as wide at base as at apex and 

 nearly as wide at apex as long down the middle, emargination tri- 

 angular and shallow, not extending more than one-fifth the length 

 of the labrarea from apex toward base, labrarea at base apparently 

 somewhat more than one-third as wide as the labrum which latter 

 has a fringe of golden hairs, base of mandibles and eye nearly adjoin- 

 ing, the malar space accordingly represented by not much more than 

 a shining line, mandibles black with the apical half mostly reddish,

 half, typical in shape, palpi slender, nearly typical; thorax covered 

 with whitish hairs that are short and close together on the dorsum 

 and long and more separated on the pleurae and sternum, dorsulum
