Hah. Japan {Nikko). In coll. British Museum. 



A specimen of a female in my own collection, from North For- 

 mosa, agrees very nearly with the species from Japan. Mr. W. B. 

 Pryer collected specimens of what may probably be this species 

 in Chekiaug, North China. 



3. Caduga loochooana, n. sp. 



Female. Duller-coloured than Japanese or Formosan specimens : 

 fore wing pale brown ; the subapical spots shorter, the discal 

 spots regularly quadrate in shape, the submarginal series being dis- 

 posed in a more regular linear row and transversely narrower : 

 hind wing paler, but of a brighter red ; the cell cleft by a distinct 

 straight red streak starting directly from the discocellular veinlet.

Differs from C. melaneus in its shorter and comparatively more 

 regularly triangular fore wing and shorter hind wing, the markings 

 being of a decidedly darker tint of blue ; they are similar on both 

 wings, but smaller, narrower, and with broader black interspaces ; 

 on the underside the hind wing is of a chestnut-red colour.

 the posterior streak below the cell shorter and traversed by a slender 

 black streak : hind wing with the inner discal series of spots smaller,
