LEPIDOPTERA.

the anal region, the exterior one is bedded in an irregular rufous patch, which has an undulated 

 interior margin, and tapers off at each extremity in a short striga; the interior one, situated on 

 the anal appendage itself, is surrounded by a white fringe, the intermediate space being occupied 

 by a greenish metallic spot, and the oblique portion of the anal angle is marked by a black stripe 

 covered by a branch from the rufous band. The body is dark blackish brown, the eyes are bor- 

 dered by a white streak; the antenna are black annulated with white and terminated by a grayish tip. 

 A single male specimen, in perfect preservation, is contained in our series : the narrowness and lengthened 



form of the hinder wings, with a slight posterior excavation, as represented in the description, obtains also 



in the two succeeding species.

Wings of the male, above, agreeing in colour with those of the species last described ; contour of 



the hinder wings likewise similar : underneath gray with pale ochraceous-brown posterior borders, 



spreading over the tip and more intensely coloured exteriorly; a narrow delicately striped band, 



consisting of two parallel brown strigse edged with white and an intermediate yellow thread, 



which is more distinct in the hinder wings, extends across the middle of both pair, being regular 



in the former and somewhat interrupted in the latter, until it reaches the anal region, where it 



passes, after an ahrupt curve, irregularly flexuose to the inner margin ; on the disk of each wing 



stands a short transverse double litura; the anal appendage is oblong, black on the surface, 



fringed with gray, and has adjoining to it, in the posterior margin, two ocellate spots of more 



than usual size; the exterior one presenting a regularly orbicular black spot in place of a pupil, 



and being bounded exteriorly by a narrow pale rufous ring, a more saturated narrow rufous arc 



forming the interior iris ; this is continued in form of a narrow band in an oblique course through 



the middle of the adjoining spot to the anal appendage, from whence it rises again for a short 



distance along the extreme angle of the wing, being edged exteriorly by a black streak covered 



with greenish silvery irrorations : an obsolete series of three successively paler black lunules, of 



which the first is covered with a silvery crescent, stands exterior to the large ocellus in close 



contact with the posterior margin. The head and body are brown above. The thorax is covered 



with lax white hairs and the abdomen with shorter yellowish hairs underneath. The antenna 



are banded with white and tipt with rufous. 



A single male specimen in a perfect state is contained in our series.
