2 Notes on the Lepidoptera of America. 
This species may at once be distinguished from G. faunus, 
by its smaller size, and the distinct ornamentation of the under 
surface, which wants all the green scales and spots which 
characterize its congener, as well as the dusky fulvous apical 
and terminal shades which oceur on both wings beneath in G. 
faunus. Messrs. OC. T. Robinson and F. G. Sanborn have com- 
municated the specimens which form the basis of the present 
description. This species appears a more closely knit form 
compared with either G. C-argenteum, or G. faunus, when the 
narrower serrations of the external margins of the wings and 
its total appearance are taken into consideration. 
Mr. Scudder’s remarks, in his “ Butterflies of New England,” 
Proc. Essex Institute, April, 1863, undoubtedly apply to Grapta 
gracilis, and are as follows: 
“T have taken four specimens of a Grapta at the White 
Mountains from the valleys to the summit, which may possi- 
bly belong to this species (7. ¢. G. C-argenteum, Avrby), but 
seem to indicate the presence of a new species; it is fully as 
small as, if not smaller, than G. C-argentewm, its upper sur- 
face is like that of G. fawnus, while its under surface is more 
like G. C-argenteum, but differs from that in having the 
broad ashy band quite hoary, nearly white, and extending also 
with equal distinctness across the secondaries; the discal spot 
of secondaries is a white |, with both limbs nearly equal simi- 
lar and straight.”—I]. ¢. p. 169.

Female. Head, above, and prothorax, covered with dark brassy 
yellow scales; the tips of the palpi are stained with the same 
shade. Thorax and abdomen, above, blackish, clothed with lateral,
