fuscous along outer and ventral surfaces, whitish on dorsal and inner 

 surfaces; apex of third segment whitish in both sexes; second segment 

 in female usually with ventral half fuscous and dorsal half and most 

 of inner surface whitish, occasionally all of outer side fuscous. 



Thorax : Collar and tegula light gray ; dorsum light gray, partially 

 irrorated with fuscous; venter largely grayish white. Ventral surfaces 

 of femur of pro- and mesothoracic legs grayish, heavily irrorated with 

 fuscous; dorsal surface grayish white; tibia and tarsus dark fuscous 

 except for whitish bands encircling apices of each segment; meta- 

 thoracic leg paler in color; femur almost completely pale gray, with a 

 long dorsal fringe of whitish hairs. Forewings pale gray, heavily marked 

 with a somewhat variable pattern of fuscous scales concentrated pri- 

 marily along middle of costa and near apex of discal cell; dark oblique 

 band traversing base of wing usually incomplete; a submarginal fuscous 

 band often present but diffuse, usually more indented at vein 6 than in 

 C. niponensis ottawana; marginal fringe pale gray. Hindwings uni- 

 formly gray. 



Abdomen: Dorsum and mid- venter pale gray; basal two-thirds of 

 lateroventral surfaces with a broad streak of dark fuscous. 



Male genitalia (fig. 60). — Uncus reduced, broadly rounded, with 

 a dense cluster of elongate setae arising from posteromedial margin 

 near juncture with tegumen. Tegumen with apex broadly excavate, 

 lateral angles somewhat pronounced. Gnathos relatively short, less 

 than half the length of valva, with apex spatulate and bearing a dense 

 cluster of elongate setae arising some distance below apex near middle. 

 Valvae with a blunt, claviform ampulla arising from apex of sacculus ; 

 cucullus broad at base, tapering to an acute apex. Aedeagus with three 

 longitudinal rows of dense cornuti; one row, bearing the longest 

 apical spines, usually with a conspicuous median gap devoid of spines ; 

 juncture of ejaculatory duct above middle; termination of duct with 

 two dense rows of elongate, minute spinules. 



Female genitalia (figs. 76, 93). — Ovipositor elongate; posterior 

 apophyses more than twice the length of anterior pair. Lamella ante- 

 vaginalis of a somewhat complex structure consisting of two pairs of 

 lateral folds, one of which overlaps along the midline, and an entire, 

 bilobed, dorsal layer; lobes rounded and separated by a relatively 

 shallow cleft. Antrum elongate, swollen with thickened, densely 

 papillose walls, becoming abruptly constricted at juncture with 

 ductus bursae proper. Walls of ductus bursae reticulate to and slightly 

 beyond union with corpus bursae, the latter being primarily membra- 

 nous and containing a pair of strongly furcate signa; each branch of 

 signum relatively slender.
