Several specimens from Oiwake in Fryer's collection. 



The Japanese examples of P. tersata more nearly approach 

 var. tetricata, Guen., than the type form, but they are not 

 quite identical with either. 



Var. chinensis, nov. 



Smaller than typical specimens and rather redder in colour ; 

 less striated with white, and the submarginal white line is 

 much obscured ; there is a dusky shade before the second 

 line of primaries and also one before the submarginal line, 

 the latter is connected with an oblique streak from apex.

Phibalapteryx unibraria. 



Scotosia umbraria, Leech, Entom., Suppl. p. 53 (May 1891). 

 Superficially resembles Scotosia rhamnata, but it is larger 

 in size and has an oblique cloud-like central fascia most con- 

 spicuous in the male ; in the female the costal portion of the 

 outer edge of the fascia is more conspicuous.
