ceno, P. Dognin); St. Jean, Maroni River, French Guiana 

 (W. Schaus); Rockstone, Essequibo River, British Guiana 

 (W. Schaus); and Omai, British Guiana (W. Schaus). Her- 

 rich-Scheaffer figures a male without the black discal dot, but 

 in my specimens it is more generally present than absent, va- 

 rying in size when present from a mere rudiment to a distinct 

 mark. 



ZADALCERA, new genus. 



With the structure or Dalcera, but vein 11 stalked with 

 veins 9 and 10, shortly so, while veins 9 and 10 are long- 

 stalked. 



Type: Dalcera fumata Schaus. 



Zadalcera fumata Schaus. 



Dalcera fumata Schaus, Proc. Zool. Soc. London, L':!8, 18!4. 

 Five males before me, all from Castro, Parana, Brazil. The 

 species is superficially very close to Dalcera abrasa, distin- 

 guished by the smoky shadings along submedian area and the 

 curved inner half-band. 



Zadalcera arhathodota, new species. 



Fore wing carneous yellow, the costa and fringe without the pink 

 tint. Hind wing orange yellow. Expanse, 50 mm. 



One female, Rio Janeiro, Brazil (Geo. Franck collection). 



Type No. 13056, U. S. National Museum. 



Coloration very much as in Dalcera abrasa, but the wings 

 less oval and drawn out toward the apex, being of a more nor- 

 mal shape. The coloration is less intense.
