 ticis basi grisescenlibus, tunc Jlavescentibus, maculis argenteis 

 nigraque bipunctata. 



"Expanse about 1^ inch. The upperside brown, somewhat dark. 

 The front wings entire and without spots ; the hind wings dentated, 

 whitish towards the anal angle, with a series of three black spots, 

 the middle one very large. 



" The underside of the front wings is the same colour as above, 

 with two ferruginous lines, transverse and waved, independent of 

 which there is along the outer margin a series of nine or ten silver 

 spots, rather brilliant. The underside of the hind wings is greyish 

 towards the base, with two ferruginous lines, being a continuation 

 of those in the front wings ; becoming yellow towards the apex, with 

 seven silver spots, five of them somewhat globose, placed parallel to 

 the outer margin ; the two others, especially the one near the inte- 

 rior margin, elongated and touching the ferruginous line ; between 

 the fourth and fifth globose spots there is a large oval black one 

 placed transversely and enclosing two large silver spots ; upon the 

 outer margin, which is of the same grey as the base, is a double 

 blackish flexuous line." — Enc. Meth.
