the and 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 strlga; the interior one^ situated on 

 the anal appendage itself, is surrounded by a white fringe, the intermediate space beirig 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 eijes are bor- 

 dered by a white streak; the antenna are black dnnulated 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, nntil it reaches the anal region, where it 

 passes, after an abrupt curve, irregularly flexuosa 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 v/hite 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.
