In males of this Eastern variety the subapical band of primaries 

 is separated by a long interval from the internal patch, as in the 

 "Western varieties of the species. 



35. ACR^EA SERENA, var. PERRUPTA.

This variation is barely separable from A. serena, var. buoetoni 

 but the male of the latter is usually more brightly coloured, with 

 blacker borders and the black lunate patch closing the cell of the 

 primaries never tending to join the outer borders by means of an 

 intermediate spot : the females of both are extremely variable.

Not only is there one perfectly intermediate specimen between

 variety A. sganzini was taken on May 2nd in copula with the 

 variety A. daira.
