broad, somewhat bulged but not extended backward into cowllike 

 lobe, its central dorsal area evenly excavate; apical half digitate; 

 apex blnnt and slightly hooked. Harpe with apex rounded (cucullus 

 tapering) ; basal process of costa produced (the basal processes of 

 the right and left harpes fusing to form a complete, sclerotized 

 transtilla) ; sacculus folded upward toward apex (an appreciable 

 depression in harpe just above sacculus). Anellus consisting of 

 ventral plate and a sclerotized, somewhat roughened dorsal piece, 

 the latter with a very few minute spines (2 or 3) on the ends at- 

 tached to aedeagus. Aedeagus cylindrical, smooth; apex flaring 

 into a wide mouth (labeose).

Alar expanse, 20-25 mm. 



Genitalia with gnathos beaklike; lateral arms developed; in ventral 

 aspect with basal half rounded (central part of lower margin deeply 

 convex) ; apical half rather narrow, not appreciably tapering; apex 

 bluntly pointed: in lateral aspect gnathos distinctly upcurved. 

 Uncus Avith basal part broad and stout and deeply, evenly, and rather 

 widely excavate ; apical half digitate ; apex rounded. Harpe slightly 

 narrowed at cucullus; apex rounded; basal process of costa pro- 

 duced into short digitus; sacculus produced at a]iex as a rather 

 prominent upfolded ridge. Anellus consisting of ventral plate and 

 a strongly sclerotized dorsal band, which partially encircles aedeagus ; 

 each extremity of dorsal band bearing a cluster of very dark, mod- 

 erately long, stout spines; ventral plate with upper margin broadly 

 incised and lateral margins concave. Aedeagus cylindrical, rather 

 slender, of nearly equal width throughout, a few minute scobinations 

 on under surface near apex ; penis bearing a thin, short line of minute 

 cornuti.
