NORTH AMERICAN ACROLOPHIDAE — ^HASBROTJCK 637 



Tegumen glabrous; lateral arm of medium width, narrowing toward 

 base ; dorsal area narrowing mesad, with mesal portion curving caudad 

 and filling emargination in base of uncus. 



Harpe simple, sublinear and with approximate basal three-fourths 

 very slender in lateral aspect. Costa and sacculus fused, greatly- 

 reduced, very narrow, comprising approximate basal three-eighths of 

 harpe, glabrous except for sparsely punctate and setose ventrocaudal 

 margin of sacculus, narrowing slightly to base. Cucullus indistinctly 

 fused with costa and sacculus, elongate, considerably enlarged distad, 

 comprising approximate apical five-eighths of harpe, markedly capi- 

 tate in lateral aspect, directed slightly ventrad; heavily punctate and 

 setose (especially so distad and on ental surface) ; apical half directed 

 somewhat mesad, basal thu'd very narrow, central thu-d expanding 

 distad, apical third broadly and evenly expanded and rounded. 



Transtilla with arm typical; slightly sinuate, glabrous, terminating 

 subacutely distad of base of harpe. 



Uncus simple. Dorsal aspect: base broad, subtriangular, latero- 

 basal angles set off from tegumen, punctate except for glabrous mesal 

 area and lateral margins, lateral margins converging into uncal 

 process. Uncal process fused with basal area, tubular, rather short 

 and stout, sparsely punctate and setose dorsad at base, evenly curving 

 caudo ventrad, narrowing to acute apex. 



Gnathos fused, moderately sclerotized, glabrous, flattened, directed 

 ventrocaudad, of medium length and width, lateral margins sublinear 

 and subparallel, apex broadly and evenly rounded. 



Anellus membranous, unarmed, juxta absent. 



Aedeagus short, stout, glabrous, asymmetrical, sublinear in dorsal 

 and ventral aspects, basal and apical portions curving somewhat 

 ventrad in lateral aspect, base unexpanded, basal half cylindrical and 

 of constant width, apical half opening broadly dorsad and consisting 

 of well sclerotized ventral strip evenly narrowing distad to acute apex. 



Vesica membranous, of medium size, bulbous, armed dorsad with 

 approximately 15-20 cornuti. Cornuti quite small but distinct, 

 mostly uniform in size, well sclerotized, acute, chiefly located in single 

 row extending along meson or in two parallel rows bordering mesal 

 area of vesica, usually directed distad or nearly so.
