The characters bj- which Felder distiuguished eurotas and ctesias are purely 

 individual. The body of the type-specimen of ctesias is much compressed ; it may 

 have been brought to Bogota from Eastern Ecuador in a pocket-book. The specimens 

 named eurotas are said to be from the Upper Rio Negro, where no recent collections 

 have been made. The species probably extends eastwards between the Amazons 

 and Rio Meta. 



(?. Cell-patch of forewing more transverse than in the preceding form, very 



variable in size like the discal spots. Discal band of hindwiug, above, obsolete 



or at least widely interrupted. 



?. Dimorphic. 



a'. ?-f. bitias resembling the male ; a specimen from Sarayafu in coll. F. D. 

 Godman. 



b'. ?-f. therapes nov. Bluish discal patches of forewing and discal area of 



hindwing less extended than in female of P. a. aristeus ; cell-patch of forewing 

 below partly creamy yellow.

e. P. aristeus vilcanotus subsp. nov. 



S. We know only three specimens, two of which are in the collection of Mons. 

 Charles Oberthiir, who received them from Staudinger under the above name, which 

 we accept, a third specimen from the same source being in coll. Adams. 



They agree with the preceding form, but differ in the cell-patch of the forewing 

 and the costal spots of the hindwing being ochraceous on the upperside, the discal 

 patches of the forewing above being washed with buff proximally ; cell-patch below 

 clayish.
