7. Carina on mesosternum in front of each middle coxa angled medially and at the 



angle usually produced as a tooth; nervellus ending beyond, at, or just before 

 the juncture of cubitella with discoidella (pi. 1, fig. 5). 



Priocneniioides (p. 49) 



Carina on mesosternum in front of each middle coxa evenly curved; nervellus 



ending distinctly before the juncture of cubitella with discoidella (pi. l,fig. 6). 



Cryptocheilus (p. 67) 



8. Anal lobe elliptical, the apical half of its hind margin evenly curved (pi. 1, fig. 7) ; 



fore tibia of female without a single, unusually stout bristle on its outer apical 

 corner; nervulus beyond the basal vein by about 0.7 to 1.3 its length (pi. 1, 



fig. 7) ; pronotum of normal length Priocnemis (p. 80) 



Anal lobe subtriangular, the apical half of its hind margin rather straight 

 (pi. 1, fig. 8) ; fore tibia of female with a single, very stout, blunt, spinelike 

 bristle at its outer apical corner; nervulus at the basal vein or beyond it by 

 less than 0.3 its length (pi. 1, fig. 8) ; pronotum quite short.
