 area of the forewing and on the disc of the hindwing, on the nnderside. The 

 yellowish marginal spots of the fore- and hiudwing are sometimes enlarged.

One of the most interesting features of this species is the jieculiar distribution 

 of its geographical varieties. While the American continents, from Buenos Aires 

 to the southern Atlantic states of the United States, are inhabited by one single 

 subspecies, the West Indian islands appear to have each a special subspecies. On 

 the continents and the Greater Antilles the species is very common in open ground, 

 while it is decidedly rare on the Lesser Antilles, having perhaps become rare in 

 consequence of extensive cultivation of the soil. There are quite a number of 

 islands from which the species has not been recorded, though it doubtless e.xists there, 

 probably in special forms, for instance on Barbuda, Grenada, St. Christopher, etc. 

 In the position of the band of the hindwing the subspecies from Martinique is the 

 most difierent from the ordinary continental form ; the Sta. Lucia subspecies is 

 characterised by an exceptionally broad band on both wings ; the Guadeloupe form 

 is extreme in the reduction of the number of spots on the forewing, the Haiti and 

 Jamaica forms deviate from all the others in the absence of the njqjer process of the 

 harpe. 



In all the subspecies the band of the upperside of fore- and hindwing is on the 

 whole rather wider in the female than in the male.

Upperside. — Forewing : a band of spots as in P. polyd. polydamas, spots SC' — R- 



a little farther away from margin. Hindwing : band curved, about five mm. 



from cell, not essentially different from that of polyd. polydamas ; creamy white 

 marginal spots distinctly enlarged, resembling those of P. archidamas ; marginal 

 teeth broader than in polyd. polydamas.
