Papilio Atratus. Cram. pi. 365. fig. A. B. ? 

 Wings above, in the female, shaded with violet-blue from the base towards the margin, on a 

 brownish ground transmitting a white patch on the disk ; exterior and posterior margins of the 

 fore wings, dark blackish brown ; hinder wings along the posterior margin marked with a series 

 of oblong brown spots, enclosed by two undulated white threads, the interior one being bounded 

 by a deep brown fascia, and the exterior one by a blackish margin fringed with grayish brown. 

 Wings underneath brown, with a shade of silvery gray; anterior with nine, posterior with ten 

 white strigas, three of which are marginal extending uniformly through both pairs ; in the ante- 

 rior wings these strigae follow each other, after nearly equal intervals, from a small vacancy at 

 the base to the marginal series ; they do not arise in contact with the costa, but a small inter- 

 vening space is occupied by four marginal dots, in irregular succession, of which the two pos- 

 terior ones are most distinct ; the first three interior strigae are parallel and nearly regularly 

 transverse ; the fourth is very short ; the fifth extends across the surface with a slight obliquity 

 inwards ; the sixth terminates in the middle of the surface : in the posterior wings, seven trans- 

 verse strigae occupy the whole surface to the marginal series ; the basal one is short and obscure, 

 the remaining are broken, and a short lineola is placed in some cases, intermediately between 

 the successive strigas ; they have a very slight curve towards the anterior margin : there are three 

 anal ocelli, agreeing in character with those of the last described species ; one exterior, near the 

 margin large and regularly orbicular ; the next reniform, with a more saturated tint at the lobe 

 which touches the interior ocellus situated at the extreme anal angle, and more pronounced 

 than in the allied species ; the two anterior ocelli are connected by a short streak of silvery 

 irrorations covering their inner border, and bounded by a short rufous fascia. The antenna 

 and abdomen are obscurely banded with white : the thorax and the body anteriorly are covered 

 with gray hair.

 brilliant sea-green ; anterior wings with a broad black posterior border stretching towards die
