 17. — Posterior legs more or less thickly pubescent; maxillary palpi 6-jointed..l8. 

 Posterior legs without long pubescence ; body short, broad, robust, orna- 

 mented with patches of depressed, pale, scale-like pubescence, as in 

 Epeolus ; second submarginal cell conspicuously shorter than the 

 third, receiving the first recurrent nervure at or near the tip, the 

 third submarginal cell narrowed towards the marginal and receiv- 

 ing the second recurrent nervure at about the middle ; marginal 

 cell long, lanceolate, obtuse at tip ; thorax short, broad, convex, lon- 

 gitudinally impressed above ; scutellum subbituberculate, without 

 lateral teeth ; legs not unusually robust, basal joint of the tarsi 

 long and narrow, the spur at the apex of the intermediate tihife 

 long, robust and obtusely bidentate at tip ; abdomen short, broadly 

 ovate, convex above, apex of sixth segment bidentate ; head nar- 

 rower than the thorax, and placed low down, formed much as in 



Epeolus Ericrocis Cress. 



18. — First submarginal cell longer than the third, which is narrowed towards the 

 marginal; abdomen with short velvety pubescence; legs % un- 

 usually long, the femora swollen, the pubescence short, the scopa 



on posterior legs f long and thin Einplior Patton. 



First and third submarginal cells of about equal length, the second smallest. 

 Proboscis when folded extending beneath the thorax as far as to the base 

 of the abdomen ; posterior legs f with a long loose scopa, and ven- 

 ter with long loose pubescence ; maxillary palpi with joints 1 and 2 

 equal, joint 1 of labial palpi ciliate, not half the length of 2.
