 long as the thorax or longer; maxillary palpi 4-jointed.

Xenoglosjsa Smith. 

 17. — Posterior legs more or less thickly pubescent; maxillary jM'lpi fi jointed. .18. 

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

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

 Epeolu» ; 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 impres.se<l above ; scutellum subbituberculate, without 

 lateral teeth ; legs not unusually robust, basal joint of the tai-si 

 long and narrow, the spur at the apex of the intermediate tibia' 

 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, formci much as in 



Epeolua 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 9 long and thin Emphor 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 alxlomeu ; posterior legs 9 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. 



Entecliiiia Patton. 



Proboscis not elongate; posterior legs 9 with a long dense scopa, and 



venter with long dense pubescence ; maxillary palpi with joints 2 



and 3 nearly twice as long as 1, joint 1 of labial palpi longer than 



2 Diadasia Patton. 



19. — Marginal cell short, broadly truncate at tip IVrdita Smith. 



Marginal cell elongate, lanceolate, acuminate at tip, rarely truncate 20. 



20. — Antennte % very much lo.iger than in 9 : body, at least the thorax, thickly 

 pubescent; fii"st and second submarginal cells subequal in length, 

 the second rather the longest; maxillary palpi 6-jointcd. 



Encera Scop. 



Antennae subequal in length in both sexes, rarely a little longer in % 21. 



21. — Second subnuirginal cell subquadrate, but slightly if any longer than high, 

 ani iispicuously smaller than the first; first recurrent nervure 

 ofte ' iting with the firet transverse cubital nervure ; body naked ; 

 maxi ry palpi 6-jointed Prosopis Fabr.
