LEPIDOPTERA.

The arrangement of these strigae is permanent and affords clear characters for a specific distinc- 

 tion. The hinder wings are marked between the base and margin with six ti-ansverse strigae, 

 agreeing generally with those of the two last described species Mlianus and Celerio, the only 

 apparent difference is that they are somewhat broken and interrupted in their course. The 

 anal ocelli are not in any degree different from those of L. Celerio. The thorax and anterior part 

 of the abdomen are covered with a grayish or light blue and silvery down : the sides of the 

 abdomen and the antennce are annulated. 

 Our collection contains one specimen of a variety on which a pure azure extends uniformly over 

 the upper surface.

 Wings above, in the male, pale violet-blue, which tint being almost equally diffused over a grayish, 

 brown ground, has, in a certain position, a pale silvery reflexion ; margin terminated by a very 

 narrow brown thread and a grayish fringe ; in the female a defined brown border extends along 

 the exterior and posterior margins of the anterior wings, on the base and disk the violet colour 

 is deeper than in the male, and the silvery gloss is more intense ; the hinder wings have a series 

 of dark brown spots parallel with the posterior margin, of which the penultimate one, opposite 

 the caudal appendage, has a deeper tint : these spots are bounded exteriorly by an intense 

 white thread, and interiorly by a series of obscure lunules directed outward. Underneath the 

 wings are grayish brown with a pale silvery reflexion, the anterior pair having seven, the pos- 

 terior pair ten white strigae, of which three are marginal, continued uniformly through both 

 pairs to the anal ocelli, and bounded exteriorly by a deep black thread. On the anterior wings 

 the medial portion is marked by two pairs of strigae, extending half across the surface, being 

 here terminated abruptly at one of the longitudinal nerves ; their direction is regularly trans- 

 verse and they are slightly undulated ; the interior pair is short, and arises at a small distance from 

 the costa ; in the intermediate space a small dot is regularly opposed to each striga ; the second 

 pair touches the costa and reaches regularly to the disk ; in the posterior portion of the surface 

 one striga opposed to each of these pairs, is continued parallel with the other to the interior 

 margin. In the hinder wings, the strigae, seven in number, are not arranged in pairs, but 

 follow nearly at equal distances, broken and interrupted by obscurer lines, without any curve 

 in the anal region : the basal one is minute, close to the thorax, and in some individuals very 

 obscure. Three ocellated spots of an intense black colour, but very unequal in size, are placed 

 in the anal angle at the posterior margin ; the exterior one is very large, regularly orbicular, 

 bounded interiorly, and at the sides by a very narrow yellowish brown iris, and exteriorly by a 

 crescent of silvery irrorations; adjoining to this is an excavated irregularly reniform spot, which 

 touches a minute ocellus at the extremity of the anal angle; the intermediate spot is marked 

 interiorly with silvery irrorations and a rufous crescent, and the extreme ocellus is also slightly 

 spangled. The tails are brown, tipt with white ; the body, brown above, and white underneath ; 

 the antenna brown, very obscurely banded with gray.
