598 PROCEEDINGS OF THE NATIONAL MUSEUM vol. in 



Tegumen with lateral arm of medium width, narrowing to point of 

 articulation with vinculum, cephalic margin sinuate, small punctate 

 area along dorsocaudal margin; dorsal area rather broad, glabrous, 

 cephalic margin broadly and evenly emarginate. 



Harpe simple. Lateral aspect: sublinear, broadest in central area. 

 Costa and sacculus fused, rather broad, comprising slightly more than 

 basal half of harpe, dorsal margin quite heavily sclerotized, narrowing 

 only slightly to base, glabrous except for heavily punctate and setose 

 caudo-ental area markedly produced en tad and dorsad and terminating 

 subacutely. Cucullus partially set oflF from costa and sacculus by 

 areas of reduced sclerotization, heavily punctate and setose in 

 apical ental half, basal half mostly glabrous, apical half considerably 

 expanded (especially ventrad) to give capitate appearance, apex 

 broadly and evenly rounded. 



TranstUla with arm typical; linear, glabrous, slightly convergent 

 with costal margin, approximately one-fourth as long as harpe, 

 terminating well above base of harpe. 



Uncus distinctively bifid, although somewhat atypically and ob- 

 scurely so. Dorsal aspect: mesal area occupied by elongate, narrow, 

 triangular, caudal extension of tegumen; lateral areas sparsely pimc- 

 tate, regularly converging and narrowing to apices; angle of bifurcation 

 extremely small and obscure; furcae pressed tightly together so as to 

 appear fused, narrowing distad. Lateral aspect: basal portion ex- 

 tending caudad, gradually expanding ventrad at point of bifurcation; 

 furcae less obscurely separate in this aspect, narrowing considerably 

 toward apices; apices directed strongly ventrad and terminating very 

 acutely, occasionally overlapping. 



Gnathos paired; arms narrow, heavily sclerotized, overlapping so 

 closely as to appear to be a single process, directed ventrad and 

 slightly caudad, apical portions minutely scobinate, apices narrowly 

 rounded. 



Anellus membranous, glabrous, juxta absent. 



Aedeagus of medium length and width, cylindrical, asymmetrical, 

 glabrous, sublinear in dorsal and ventral aspects, basal fourth directed 

 somewhat ventrad in lateral aspect; base slightly expanded and 

 emarginate in ventral aspect, opening dorsad; apical third opening 

 broadly dextrad. 



Vesica membranous, dextral margin armed with indefinite row of 

 12 or more cornuti. Cornuti minute, weakly sclerotized, indistinct, 

 unequal in size, with acute apices, directed caudad.
