 middle of the second and third tergites, apical edge of first, second, 

 third and fourth tergites with a pale stramineous border, second 

 tergite with its elevated portion down the middle : depressed por- 

 tion :: 16 : 8, fifth tergite shining, reticulate, its punctures coarser 

 than on the other tergites, pygidium nearly planate, almost pointed 

 at apex, tergum with inconspicuous, pale, nearly erect hairs in 

 addition to the hair bands, the hairs of the sides of the first and 

 second tergite much longer than the hairs of the succeeding tergites,

 ochreous almost white hairs; head with its facial line : transfacial 

 line :: 56 : 76, axial line : temporal line :: 30 : 18, malar line : joint

 lateral ocellus :: 5.5 : 5, elevated portion of malar space nearly as 

 long as depressed portion, head covered with white hairs, front 

 rather indistinctly, longitudinally striate, not elevated into a welt

 line : : 3 : 14, fovea attenuated below its middle where it is apparently 

 only one-half or a little more than half as wide as the greatest width of 

 the fovea, the latter continued to a point apparently a little below the 

 .antennal line, fovea filled with dark seal -brown hairs, fovarea wanting, 

 vertex and temples along the upper edge of the eye with black 

 hairs, face mostly polished, partly indistinctly reticulate, with indis- 

 tinct punctures that are as many as five or more puncture widths 

 apart, clypeus slightly elevated above the apical margin, convex, 

 sculptured like the face except that the punctures are larger and 

 well defined, clypearea present but poorly defined, clypeus thinly 

 hairy its sculpture not at all hidden by hairs, labrarea subemarginate
