RHOPALOCEKA FROM FORMOSA. 333 



instead of five as given in Kershaw's figure (f. 5), otherwise they agree 

 well. The third specimen near phoenix taken in April differs in having 

 only four spots, the one near abdominal margin being absent.

Collection number 96. Two male specimens, Tainan, July. 



These specimens agree well with Kershaw's figure. He remarks that 

 " the light yellowish white spots on the forewing vary much in size, but 

 the three spots in the median interspaces are usually large and distinct,

 the underside of the hindwing are usually five in number, but often they 

 are indistinct and one or two perhaps obsolete ; the sexes are very much 

 alike." 



Distribution. Hongkong ; Formosa.

One of the male specimens agrees very well with Leech's figure of 

 sumitra, the chief difference being that the three superior apical spots 

 near apex of costal margin are not placed in a straight line but more 

 in a curve. The shape of the first and second, large, quadrate, semi- 

 transparent white spots of the oblique discal series differs some-
