spots. The black mark at the apex of the cell of the forewing beneath scarcely 

 larger than the ronnd spot in the middle of the cell. Thoracical black spots more 

 extended than even in intermedia, the prothoracic lobes being black with u narrow 

 yellow border. 



?. Agrees with the S\ hiudwing below with a minute black dot in the middle 

 of the cell, and a slender spot upon the discocellnlars.

(?. Forewing as in albi/erajhwt the outer black dots of the base of the forewing 

 confluent as in transiens; outer part of submedian fold within white area fiiintly 

 marked with brown scales ; white area slightly notched between veins 2 and 3 {type), 

 or not notched between these veins. Hindwing above with one spot at the end of 

 the cell, this spot as large as in perseeta ; below, there is a second spot of variable 

 size in the middle of tlie cell ; no postmedian spots. Thoracical spots as in transii'/is. 

 The brown ill-defined spot between veins 7 and 8 of the hindwing below is joined to 

 the brown border of the wing. 



In one male the white patch at the upper angle of the cell of the forewing above 

 is shaded over witli brown scales. 



?. Like d, but hindwing with one spot only, which stands at the apex of the 

 cell ; this spot somewhat smaller than in the c? ; the anterior half of the cellule formed 

 by veins 7 and 8 of the hindwing below is all brown, instead of this cellule having 

 merely a brown spot beyond the middle of the costal nervure.

The specimens of plana from Bulo Laut (south of Borneo), Java, the lesser 

 Snnda Islands, and the Tenimber Islands belong all to one subspecies. A. plana 

 plana is distinguished from the preceding races especially by the hindwing below 

 having only one very small black spot at the apex of tliecell; seldom there is a second 

 minnte spot in the middle of the cell. The white patch at the upjicr angle of fhc 

 cell of the forewing is mostly joined to the white area of the wing; the outer liiack 

 spots of the basal area are merged together to a transverse band. Tlie thnraiical
