iu the two Central American subspecies and in the Sonth American snlispecies, 

 but is nsuiilly absent or only vestigial in tlie subspecies inhabiting Colombia, 

 Panama, and North Venezuela. In this geographically intermediate sidisjiecies 

 the submedian band of the underside of the hindwing crosses the cell at or 

 liroximally of M\ while in the northern races and in the southern one this band 

 is much more distal. On the other hand, the Central American and Colombian 

 races differ from the southern subsj)ecies in the scales of the black marginal and 

 postdiscal bands of the forewing being broader and the bands therefore more deeply 

 black, the postdiscal band being moreover not divided, and the black distal band 

 of the hindwing, above, not bearing a distinct white sjjot R- — R' proximally of the 

 white submarginal spot which stands in front of the tail. 



Another interesting feature of agesilaus are the opposite lines of devclojiment 

 obtaining in the subbasal and submedian bands of the hindwing. The subbasal 

 band, if not complete, is on the upperside usually more or less distinct from the 

 cell baclvwards, the costal portion being missing. The submedian band of 

 the upperside, if not altogether absent, is present only in the costal region, the 

 posterior portion being missing.

S- Black bands broad. Forewing: first and second bhick bands abont 

 two-thirds the width of the interspace between them, both extending to inner 

 margin, or the second at least beyond SM-; pale submarginal band not wider, or 

 even narrower, than black postdiscal band ; the latter not includiug a distinct i)ale 



line ; the scales of this band and of the marginal one rather broad. Hindwing : 



abdominal edge black from base to anal angle, black subbasal band complete ; 

 submedian band usually distinct from costal edge to cell, or at least vestigial ; 

 red aual spots separate from each otlier, each comidetely surrounded by black 

 scaling, their white anterior borders vestigial or very narrow. 



On itndcysi(h the red submedian line of the hindwing extends to hinder edge 

 of cell, its black border being heavy.
