 wing sparsely irrorated with small fuscous spots; at the end of cell 

 a conspicuous ochreous-white spot narrowly edged with fuscous; 

 cilia grayish fuscous. Hind wing grayish fuscous; cilia concolorous 

 with light basal band. Legs grayish fuscous strongly overlaid with 

 ochreous-white. Abdomen grayish fuscous above with posterior mar- 

 gins of segments ochreous-white ; beneath ochreous-white with a well- 

 defined lateral stripe on each side and a pair of black spots on the 

 posterior margin of each segment between the lateral lines. 



Male genitalia. — Harpe rather sharply narrowed before cucullus; 

 cucullus bluntly pointed; clasper long, curved, slightly dilated 

 distally ; sacculus moderately sclerotized. Anellus longer than broad, 

 slightly constricted at about middle; posterior edge concave; lateral 

 lobes large, extending nearly to posterior edge of central plate. 

 Aedeagus slender, curved, pointed, with ventral sclerotized arm by 

 which it is attached to the anellus; vesica armed with an elongate 

 patch of fine cornuti. Vinculum rounded, with well-developed dorso- 

 anterior process. Transtilla a moderately broad sclerotized band 

 with well-developed lateral lobes. Tegumen pointed. 



Ferruile genitalia. — Genital plate very broad, strongly sclerotized. 

 Ostium small, crescentic, opening slightly posterior to middle. Ductus
