Male genitalia: Harpe broadest near base, tapering gently to the 

 rounded cucuUus; clasper arising slightly beyond middle, stout, 

 distally armed with strong, sharp setae ; sacculus thickened but with- 

 out appreciable prominence. Anellus rectangular, deeply concave 

 posteriorly. Aedeagus stout, curved, sharply pointed; vesica armed 

 with cluster of strong setae. Vinculum narrow, rounded. Gnathos 

 an oval transverse spined knob. Socii small, fleshy lobes clothed with 

 fine setae. Uncus furcate, proximal stalk long, slender; distal arms 

 slender. 



Female genitalia: Ostium moderately small, ventral lip ridged,

 Inception of ductus seminalis approximately at junction of sclerotized 

 and membranous parts of ductus bursae. Signum a small rectangular

Superficially, j^m6/'wite and cristata are similar, but the hind wing of 

 cristata is considerably darker than that oi jimhriata. In the forewing 

 oijimbriata the white costal spot is more pronounced and the ground 

 color is much lighter than in cristata. The male genitalia also 

 show marked differences. Although the anneli of both species are of 

 the same type and are, for practical purposes, indistinguishable, the 

 clasper, as in the apical half of the harpe oi jimhriata, is absent in the 

 harpe of cristata. Other obvious differences wUl be seen by a compari- 

 son of the figures. Unfortunately, no female of cristata is available 

 for comparison.
