subtriangular dark fuscous blotch in disc at | ; a transverse dark 

 fuscous mark on end of cell ; a dark fuscous mark on middle of 

 costa, whence an irregular dentate interrupted or partially obsolete 

 fuscous line runs to 1 of dorsum, excurved in disc ; a very faint 

 greyish fascia between this and termen, becoming obsolete towards 

 costa ; a series of dark fuscous marks round posterior part of costa 

 and termen, on costa connected by prsemarginal fuscous dots : cilia 

 white, above apex with a short dark fuscous subbasal line. Hind- 

 wings with vein 4 absent ; ochreous-whitish, tinged with grey on 

 dorsal half ; costal margin expanded from base to |, with very 

 long rough projecting hairscales, whitish above and dark grey 

 beneath, and with projecting cilia before apex, so as to appear 

 excavated between these, and with long subcostal pencil of 

 whitish-ochreous hairs lying beneath forewiugs ; cilia white, base 

 ochreous-tinged, with a dark fuscous spot above apex. 



British Guiana, Bartica, from December to February {Parish) ; 

 five specimens. The^ absence _of „ vein 4 of hindwings (coincident 

 with 3, instead of stalked) is a notable character, but cannot be 

 regarded as more than specific in this instance, the relationship to 

 the adjacent species being so close in all other respects.
