opposite transverse streaks, tending to the anal appendage, and finally a short narrow attenuated 

 line, parallel with the oblique portion of the anal angle ; the posterior margin is confined by 

 a black marginal thread, edged interiorly by a narrow white striga, which is more pronounced 

 at the internal angle; the surface of the anal appendage is black, the tails are tipt with white; 

 the body is black above, white underneath, the sides of the abdomen being annulated ; the antennae 

 are delicately banded, and the legs are marked with broad alternate rings of black and white.

Plate I, fig. 5. 

 Wings agreeing in form, longitudinal extent, and in the notch and anal appendage of the hinder 

 pair, with the preceding species ; surface above dark brown, with a very slight ferruginous lustre, 

 being paler on the disk and more saturated at the borders ; in the hinder pair the anal region 

 is covered by a broad white patch, confined posteriorly by a delicate black marginal thread and 

 bearino- two irregularly round black spots, the exterior one being dotted with white ; the anal 

 appendage bears a black dash, attenuated interiorly and marked laterally with a greenish silvery 

 line ; the extreme fringe of the hinder pair and the tails throughout being white : underneath 

 the anterior wings are fulvous, the hinder silvery white, with a broad fulvous posterior border, 

 attenuated towards the anal region, and continued by a narrow striga passing irregularly 

 flexuose to the inner margin ; the anterior wings are paler at the base, have an obscure yellowish 

 litura on the disk, behind this a curved brown striga, increasing in breadth and intensity of tint 

 towards the interior margin, and finally a black marginal thread ; the hinder have a very deli- 

 cate linear yellowish transverse streak on the disk, a medial band of brown dots, more saturated 

 near the costa, and continued at the inner boundary of the anal areola by a very deep black 

 broad regularly transverse streak, tending to the inner margin, and accompanied, a little above 

 its termination, by a solitary black dot ; the anal region is interiorly bounded by a series of 

 diversified marks, of an intense black colour, disposed in a simple curve ; it commences, near 

 the outer apical angle, with an oblong black streak touching a wedge-shaped streak with a 

 minute dash of green silvery irrorations at its inner extremity; this is followed by two large 

 irregularly defined black spots which also appear on the upper surface, the exterior one being 

 bordered at its inner margin by a crescent of silvery irrorations, the next divided into two 



portions
