Male. — Front 0.40 to 0.42 of the head width at vertex, widening 

 immediately so that the narrov/est portion is very short; parafron- 

 tals almost entirely shining black, only the lower portion gradually 

 becoming gray poUinose; bristles in about three rows with coarse 

 hairs outside of them. Face gray pollinose, the pollen of the para-

 through perceptibly; cheek subshining black with only a little pollen, 

 half the eye height, with black hairs, the lower ones rather coarse; 

 posterior orbits rather plumbeous, shining black above, the hairs 

 below the lowest frontals black. Antennae black, reddish at junction 

 of second and third joints; second joint a little longer than usual, 

 fully half the length of the third; arista thick basally, flattened 

 toward apex, which is, however, acutely pointed. Vibrissae not very 

 high above the oral margin, the distance only about haK the length 

 of the second antennal joint; facial ridges with partly double row 

 of medium-sized bristles extending up almost to the arista. Palpi 

 blackish basally; apices brownish-yellow; beard white. 



Thorax shining black, but httle pollinose in front, the scutellum
