A common species in the Southern United States and in Central America, ranging 

 southwards as far as Costa Rica. We have a series of some forty-six specimens, six 

 only of which are females. It is a very near ally of A. hobomolc (Harris), an inhabitant 

 of Canada and the Northern States ; it differs, however, from that insect in having a 

 more spotted underside to the secondaries in the male, and the nervures of both wings 

 are fulvous (instead of black) above in this sex. 



Dr. Skinner has quite recently figured the sexes of both A. zabulon and A. hobomok, 

 and he states 5 that they have frequently been bred by Mr. Laurent. The females of 

 the more northern A. hobomok are dimorphic, but this is not the case in A. zabulon, so 

 far as at present known. For the genitalia of the male of A. zabulon, see Tab. XCIV. 

 fig. 7.

Pamphila rolla, Mab. Compt. Rend. Soc. Ent. Belg. xxvii. p. lxx \ 



Alis nitide fulvis, ad basin obscurioribus ; anticis margine exteriore ad apicem et ad angulum analem latiore, 

 venis et linea angusta discocellulari, fuscis ; posticis marginibus ad apicem anguste, aliter late, fuscis : 

 subtus ochraceis, in area discali pallidioribus,"ad basin (nisi in costa), margine interno, ad angulum 

 analem, et linea ad cellula? finem, fuscis; posticis indistincte ferrugineo maculatis, ad cellulae finem 

 puncto minuto nigrescente. 



9 . Alis fuscis, anticis maculis quinque in serie sinuata obliqua, secunda maxima, punctisque tribus in linea 

 transversa subapicalibus, flavis : subtus anticis ut supra, sed litura submediana magna ; posticis griseo et 

 fulvo marmoratis.

Mabille compares this insect with A. zabulon, but it is perhaps more nearly allied 

 to A. perfida (Moschl.), which it somewhat closely resembles in the structure of the 

 male genitalia. The male of A. rolla may be distinguished from the same sex of 

 A. perfida by the very broad dark margins to both wings, and from that of A. zabulon 

 and A. hobomok by the different coloration of the underside of the secondaries. 

 Seven male specimens are before us, six of which are from Costa Rica, one of these 

 latter being shown on our Plate. For the genitalia, see Tab. XCIV. fig. 10.
