 ajax altogether.* 



The subspecies of P. poli/xenes, which name comes next in priority after ajax, 

 do not all corapletel_v grade into one another. The differences are, liowever, so 

 slight that the close connection between the various forms becomes at once evident 

 on comparing a long series.

c? ? . Specimens which resemble the following subspecies in the width of the 

 yellow discal band can be distinguished by the last spot of this band on the 

 forewing being produced basad and by the black basal area of the hiudwing 

 below being much less sharply defined, gradually shading off. 



The subspecies is remarkably dichromatic, in one extreme the yellow colour 

 of the liindwing extending to the very base, while in the otlier extreme the yellow 

 discal baud is much reduced. There arc all iutergnidations. The black specimens 

 were erroneonsly called pobjxenes Fabr. by Staudinger, and asterioides Reak. by 

 Maassen & Weymer and by Strecker. 



a', f. amcricus Kollar, I.e. The discal baud of the forewing, above, is often 



washed with orange, as is also the case in some specimens of P. poli/xeiies stabilis,
