The ? of this species is wholly dark wood-brown, speckled with darker ; the 

 usual pale costal patch of the S scarcely lighter than the rest of the wing : the 

 outer margin of the forewing forms an acute tooth at apex, a prominent one at 

 vein 0, and a large nasiform projection beyond 4 and 3, below which to vein 2 it is 

 incised. The hindwing likewise has a much more promiueut tooth at vein 3 than 

 the cJ. The outer line of forewing, instead of being blackish, is marked by a tine 

 whitish line. 



The example from which this description is taken came with two typical £ <$ 

 from Sapucay, Paraguay (Foster), the ? dated October 1900, the <$<$ .September 

 1002 and October 1904".
