radius elongatns, in apicis angulum siiperiorem evectus ; 

 nervus albus, tantiim non rectus ; cubiti petiolus brachio 

 superiore fere triente brevior, inferiore dimidio fere 

 longior ; furca superior longitudine media brachii dimi- 

 dium ferme sequans ; furcse inferioris ramus superior 

 basi cubito curvatus ; distantia inter ramorum apices 

 (per nervum marginalem emensa) bracliio longitudine 

 aequalis ; discus stria subobliqua, irregulari, lata, alba, 

 qufe a costse margine orta stigma dividit, deinde in brachii 

 cubitalis inferioris ramo superiore exitum habet ; apicem 

 ambit stria latiuscula, alba, a radio extremo rami supe- 

 rioris brachii cubitalis inferioris ad apicem usque extensa ; 

 nervus dorsalis marginalis fere a suturae clavalis apice 

 obscure fuscus, prteter loca ubi ramorum nervi candidi 

 fuscedinem apicibus suis interrumpunt. Pedes pallide 

 fiavi. Abdomine piceo-fuscum, nitidum.
