 the hind margin, but 8.5-10 mm. behind the cubital vein, with no clearer area 

 between this band and the proximal (or anal) wing-margin. Superior appen- 

 dages $ 5 mm. long. Hamule recumbent on genital lobe, projecting beyond it 

 by less than the vertical half of the latter. Frons <J superiorly metallic-violet.
