internal angle, which is black. The middle line is double, composed 

 of two parallel linear sinuate lines, which become obsolete on thecosta. 

 and absent on the inner margin. The third line is single, and consists 

 of the curvilinear black discal dot, and a second curvilinear line below 

 the 4th median nervale. On the costa it is represented by two paral- 

 lel brown lines, enclosing a white spot. Outside and parallel to the 

 discal curvilinear spot is a line composed of two curvilinear lunules, 

 which are geminate, and enclose a reddish brown line. From the upper 

 line extends towards the apex a very distinct white patch, dusted over 

 with ochreous scales. On its outer edge are three black internervular 

 streaks, bathed with ferruginous scales. In the middle of the wing 

 and just below is a round rusty patch. Below the median nervure and 

 its branches the wing is lio-hter, and, like the costa, covered with cine- 

 reous and dark ochreous scales. 



Secondaries pearly white, base of the fringe dark ; i> dark discolora- 

 tion on the internal angle; costa dark. Beneath the primaries are 

 dark, except in the middle portion, which is very pale. White and 

 dark dots on the costal edge, and the costo-apical white patch appears 

 through. Secondaries white, fringe discolored on the nervules. 



Length of body, .85; exp. wings, 1.60 inch.

9 . This tine species, which is of larger size than usual, is of an ashen 

 color, with an olive tinge. The head is pale, and the thorax gradu- 

 ally grows darker until on the scutellum it is almost black. On the 

 olive cinereous primaries is a sub-basal double black line which only 

 reaches the subcostal nervure; just beyond its middle it is pointed in- 

 wards. At the base of the wing the submedian and internal nervures 

 are covered with black scales, forming a fork, the upper prong of which 

 meets the transverse geminate line. A short basal geminate brown 

 line extends from the costa to the black fork. Beyond and jiist within 

 the sub-basal line are three brown patches, especially marked in the 

 submedian and internal interspaces. The middle of the wing is clear 

 olive gray. The discal dot forms a long curved linear lunate line, and 

 beyond it the extra discal interspace is tawny brown. The discal line 

 below is connected with three black lines; the two upper of which are 

 the black upper median nervules, while the lower forms the first and
