 infuscate, stigma greenish. Pronotum very broad, nearly twice as 

 broad behind as long, narrowed in front. Wings long and slender, 

 acute at tips, divisory veinlet ends much beyond the cross-vein, 

 gradates very close together, the inner series very much nearer 

 outer than to the radial sector, five or six in inner row, eight or nine 

 in outer; marginal forks two and a half times as long as broad; 

 second cubital cell much narrower at tip than the third at base. 

 In hind wings five inner and eight outer gradates. Expanse 30 mm. 

 From Cali, Colombia, 1000 m (Fassl). 



Chrysopa sarta, n. sp.
