 terior margin; triangle glossy black; face reddish yellow; antennae 

 reddish, third joint darkened on upper margin; arista brown; cheeks, 

 proboscis and palpi brown. Thorax entirely black, with very slight 

 indications of prninescence. Abdomen brown-black, slightly shining, 

 the basal two segments yellowish. Legs yellow; apical half of femora 

 and all except the extreme bases and the apices of tibiae of hind legs 

 black; tarsal claws black. Wings with a distinct fuscous area extend- 

 ing from humeral vein nearly to apex of third vein along costa and 

 covering the surface from slightly posterior to third vein to costa; 

 veins brown. Halteres black. All hairs and bristles yellowish white. 



Frons nearly half the width of head, and distinctly broader than 

 long; triangle short and broad, reaching well towards anterior margin 

 of frons ; surface hairs long, especially on orbits ; antennae rather 

 large, third joint rounded, pilosity short; arista as long as anterior 

 width of frons, its pubescence distinct and close ; cheek linear, not 

 over one-tenth the eye-height; eye about one and one-half times as high 

 as long, distinctly pubescent. Mesonotum densely covered with rather 

 long pale hairs, which are indiscriminately arranged ; surface without 

 distinct punctures or furrows ; scutellum rounded, its surface with 

 short hairs, four marginal bristles present. Abdomen short, somewhat 

 pear-shaped, the surface with many short hairs. Legs stout and rather 

 long, their surfaces covered with short hairs. Costal division from 

 humeral vein to end of first vein equal to second division ; auxiliary 

 vein complete but indistinct; fourth vein ending at wing tip; third 

 ending slightly nearer to apex of fourth than to second ; outer cross- 

 vein short, obliquely placed, its upper extremity nearer to wing tip 

 than its lower; last section of fifth vein one and one-half times as long 

 as penultimate section of fourth.
