Male genitalia. — Vinculum typical, as in other species. 



Tegumen with lateral arm of medium length and v/idth, margins 

 sublinear, strongly narrowing to point of articulation with vinculum; 

 glabrous except for small, punctate, setose, dorsocaudal area; dorsal 

 area broad, glabrous, not separated along meson, with mesocaudal 

 expansion filling broad emargination in base of uncus. 



Harpe simple. Lateral aspect: quite slender, approximate apical 

 half directed considerably ventrad; costa and sacculus fused, com- 

 prising approximate basal half of harpe, glabrous except for heavily 

 punctate and setose ental area of sacculus terminating subacutely 

 ventrocaudad at base of cucullus, broadest in apical third at point of 

 attachment of arm of transtilla, approximate basal two-thirds con- 

 siderably narrower, basal extremity subacute; cucullus indistinctly 

 separated from costa and sacculus by areas of reduced sclerotization, 

 comprising apical half of harpe, directed considerably ventrad; 

 approximate basal half very slender, very sparsely punctate and 

 setose; apical half expanded ventrad, at least twice as broad as basal 

 half, heavily punctate and setose ectad and entad, curving strongly 

 mesad in dorsal and ventral aspects; apex broad, rounded. 



Transtilla with arm of medium length and width, well sclerotized, 

 glabrous, weakly sinuate, subparallel with dorsal margin of costa, 

 terminating subacutely somewhat distad of basal extremity of harpe. 



Uncus bifid. Dorsal aspect: base large, broad, largely set off 

 from tegumen by areas of reduced sclerotization, punctate and setose 

 except for glabrous mesal area; lateral margins well sclerotized, 

 sinuate, rather weakly convergent distad; angle of bifurcation very 

 broad, evenly rounded; furcae of medium length and width, tubular, 

 punctate and setose, gradually narrowing and curving ventrad to- 

 ward apices, broadly separated, major basal portions divergent, 

 smaller apical portions slightly convergent, apices acute. 



Gnathos typically paired, lateral margins and apical portions 

 heavily sclerotized, directed mainly ventrad, apical portions cuj'ving 

 somewhat caudad; arms broad, flattened, glabrous to weakly pitted, 

 slightly divergent to strongly overlapping distad, apices very broadly 

 and evenly rounded. In some specimens (fig. 150), combined out- 

 hnes of uncus and gnathos in lateral aspect resemble semicircle; in 

 others, uncus and gnathos are drawn close together and gnathos 

 extends further caudad than uncus in dorsal and lateral aspects. 

 Anellus membranous, unarmed, juxta absent. 



Aedeagus of medium length, five-eighths to three-fourths as long 

 as harpe, markedly flattened dorso ventrad, broad in dorsal and 

 ventral aspects, slender in lateral aspect, sublinear and asymmetrical 

 in all aspects, glabrous, base unexpanded, approximate basal half 

 tubular, apical half opening broadly dorsad and consisting only of
