PWRIDM. 



The neuration of the posterior wings and the five-branched subcostal nervure, with four of its nervules very short, 

 running almost directly to the costa, the long slender abdomen, the elongate wings, and other characters, bring this 

 genus very near to the Heliconidas. It approaches the Danaida; by having the posterior margin of the anterior, and 

 the anterior margin of the posterior, wings very often dilated in the males ; in which case the posterior wings above, and 

 the anterior below, have a large shining patch, with silvery, greyish, or steel-blue reflections, composed of very minute 

 closely apprcssed scales, in the middle of which is an oval spot of a dull chalky white or ash colour. When the wings 

 are expanded these two patches exactly correspond, the shining portion of the under surface of the anterior wings 

 precisely covering the similar portion of the upper surface of the posterior. 



The form of the wings varies much, both in different species, and in the sexes of the same species. The anterior 

 wings are generally smaller and more falcate or pointed in the male than in the female, and the posterior wings larger. 

 The sexes also differ in some species very materially in colour. 



In Leptalis Medora, the middle disco- cellular nervule is so nearly atrophied that the cell at first sight appears to 

 be open. 



The habits of this genus, according to M. Lacordaire, closely resemble those of the Heliconida; ; and, like that family, 

 they are confined to the tropical, or the immediately subtropical, parts of the New World.
