Male. — Figure 18. Head and thorax as in R. zaha. Abdomen 

 straw yellow, paler below. Forewing above and below similar to 

 zaha, except that fasciae enlarged with fuscous color extending 

 along both base and apex of costa and to inner margin near anal 

 angle. Hindwing on both surfaces whitish, tinged with yellow, even 

 on costal margin below and with small cloud of fuscous at apex much 

 smaller on undersurface than above. 



Length of forewing 9.5-11 mm. (average 10.1 mm.). 



Male genitalia as characterized in key and as illustrated by figure 

 3. As already mentioned, it is characterized by dorsal plates of 

 anellus shghtly scobinate, by aedeagus greatly narrowed distally, 

 and by very broad cuiller from harpe. 



Female. — Figure 19. Very similar to male, differing chiefly in 

 having hindAvings entirely fuscous except for yellow in middle of 

 outer margin above and below and on costal margin below. Adbomen 

 yellowish brown. 



Length of forewing 11 mm. 



Female genitalia as characterized in key and as illustrated by 

 figure 12. This species has a signum similar in shape to that of 

 cora but it is transverse rather than longitudinal in position. Other- 

 wise it differs greatly from cora in the length and shape of the ductus 

 bursae.
