Male. — Front (before ocelli) 0.225 of the head width (average of

 above widening rapidly downward, beset with short hairs which are 

 thicker near vertex; median stripe brownish red, hardly at all nar-

 joint very short; cheeks about one-sixth the eye height, gray pol-

 or less inf uscated basally, beset with numerous black hairs. 



Thorax black with gray pollen; mesonotum marked with four 

 subshining black stripes, which are coalescent behind the suture and 

 narrowly separated in front appearing as two broad black bands to 

 the naked eye; scutellum reddish at tip, gray pollinose; calypters 

 opaque, white with a tawny tinge. 



Abdomen black in ground color, the sides and apex obscurely red- 

 dish; segments 2 to 4 with very distinct grayish pollen bands, 

 which include the basal half or more, the remainder shining, along
