Eead April 15, 1S67. 



Family, NYMPHALIDAE. 



Gkapta, Kirby. 

 Grapta gracilis, n. s. 



Male and Female. Upperside, much the same as in Grapta 

 faunus, Edwards ; the preapical oblique dark brown costal band 

 of the primaries is constantly more diffuse, and the succeeding yel- 

 lowish marks more restricted, than in its congener. Usually there 

 is a third fainter black spot on the interspace above first median 

 nervule. On the secondaries, the terminal dark band is narrower 

 than in G. faunus, and the sub-terminal, interspaceal, yellow- 

 fulvous marks, while deeper in color, are brought nearer to the 

 external margin ; within these, the dark color is less intense and 

 shades more rapidly to brownish, than in its congener. All the 

 exserted portions of the external margins on both wings are nar- 

 rower ; this is especially perceivable when comparing the " tails " 

 of the secondaries of the two species together. 



Underside, paler than in G. faunus, and affords ready distinguish- 

 ing characters. Basally, the wings are of a rich dark clear brown, 

 marbled with paler shadings nearer the body, and with darker lines 

 inclosing brown elongated patches. Outside of the brown space is 

 a broad whitish band, distinctly covered with fine, short, wavy, 

 transverse, disconnected, brown striae, and shading into the dark 

 wood-brown strigose terminal shade. The discal mark of the sec- 

 ondaries is a white \_, entirely surrounded by the dark brown 

 scales of the basal shade. Body and legs much as in G. faunus ; 

 tarsi, whitish, paler ; antennae notably shorter than in its ally. 



Expanse, $ & £ , 1.50 to 1.60 inches. Length of body, 0.1 to 

 0.75 inches. 



Habitat, Atlantic District (Mount "Washington, N. H. !).
