PL. XII 



under side of the hind wings has the submarginal band nar- 

 rower than in A. cybele and often wholly wanting, as shown in 

 the figure. The fore wings on the under side are redder at the 

 base than in A. cybele. Expanse 3 to 3.5 inches. 



The range is the same as that of the preceding species. 



The two species A. cybele and A. aphrodite usually are 

 found flying at the same time and in the same places, and when 

 on the wing it is often very difficult to distinguish them from 

 each other. In fact they seem to intergrade into each other, 

 and in a long series of specimens such close resemblances often 

 occur that it is puzzling to decide which is which. The deeper 

 red of the fore wing of A. cybele is the best diacritical char- 

 acter. The paler outer margin of the hind wing of A. aphro- 

 dite, which is typically shown in Plate XII, sometimes occurs 

 also in A. cybele, and I have specimens of the latter which 

 very closely approximate the former in this regard. In se- 

 lecting specimens for illustration I have chosen the two extreme 

 forms in which the pale wing of A. aphrodite is seen to contrast 

 on the under side with the darker wing of A. cybele shown on 

 Plate XIII.
