 than half-way to the small cross vein. Legs black; pulvilli of the 

 forefeet as long as, of the other feet, slightly shorter than, the last 

 two tarsal joints; inner proximal surface of femora with fine erect 

 villosity, in length nearly equal to greatest diameter of femur; 

 middle tribia with, one bristle on outer front side near the middle, and 

 with dense erect villosity on inner distal surface equaling diameter of 

 tibia; hind tibia on outside with row of four or five unequal bristles, 

 of which the distal one is much the largest and is inserted just beyond 

 the middle. 



Female. — Front at narrowest 0.39 of head width in the single speci- 

 men measured; frontal vitta with its sides parallel. Abdomen with- 

 out macrochaetae on the first segment, a minute pair of median
