dorsal area with cephalic margin emarginate mesad, caudal margin 

 convex and separated from base of uncus by irregular transverse area 

 of reduced sclerotization. 



Harpe simple. Lateral aspect: costa and sacculus fused, consider- 

 ably shortened but somewhat expanded in all aspects, comprising 

 approximate basal three-sevenths of harpe, glabrous except in ventral 

 and ental portions of caudal extremity, broadest in apical third, basal 

 half strongly narrowing to very narrow basal extremity; ventrocaudal 

 margin of sacculus digitate, punctate, setose; caudal margin of sac- 

 culus developed strongly entad into prominent, heavily sclerotized, 

 finely dentate process directed caudad. Cucullus only partially 

 separated from costa and sacculus by irregular area of reduced sclero- 

 tization, elongate, very slender, approximate apical half curving some- 

 what ventrad and mesad, margins well sclerotized and subparallel, 

 basal and apical areas slightly expanded, base weakly punctate and 

 setose, remainder of cucullus gradually becoming more heavily punc- 

 tate and setose entad and ectad toward apex, apex evenly rounded. 



Transtilla with arm well sclerotized, glabrous, approximately one- 

 fifth as long as harpe, broadly separated and slightly divergent from 

 dorsal margin of costa, terminating subacutely as far cephalad as basal 

 extremity of harpe. 



Uncus single, partially and indistinctly separated from tegumen by 

 areas of reduced sclerotization. Dorsal aspect: base large, subtri- 

 angular, large mesal portion weakly sclerotized and glabrous; lateral 

 margins heavily sclerotized, sparsely punctate and setose, linear, con- 

 verging caudad into base of uncal process. Uncal process rather short, 

 robust, heavily sclerotized, curving strongly ventrad; apex very 

 sparsely punctate and setose, acute. 



Gnathos paired, heavily sclerotized (especially along lateral margins), 

 directed ventrocaudad; arms short, broad, closely parallel, scobinate 

 dorsad, apices broadly and bluntly rounded. 



Anellus rather small, membranous, unarmed, juxta absent. 



Aedeagus somewhat reduced, approximately two-thirds as long as 

 harpe, asymmetrical, sublinear in dorsal and ventral aspects; approxi- 

 mate basal half somewhat expanded, cylindrical; approximate apical 

 half abruptly narrowed, curving ventrad through angle of 45°, 

 opening broadly ventrad and consisting of narrow dorsal strip narrow- 

 ing to subacute apex; small dorsodextral area near center of apical 

 half armed with approximately six minute, acute, well sclerotized, 

 spinelike processes appearing as serrate dextral margin in dorsal 

 aspect. 



Vesica small, elongate, slender, membranous, apparently unarmed. 



Type. — Holotype d^ and allotype 9 in the California Academy of 

 Sciences at San Francisco.
