Description of a new species of GRAPTA, and Notes on G. interrogationis. 



BY J. A. LINTNER. 

 Grapta umbrosa, n. sp. 



/'riman'cs. — Anterior margin uioclerately curved tow:ird the tip. sini- 

 ilur to comma. Tip never falcated, as in interrogationis. Posterior and 

 interior margins less excavated than in interrogationu. Above fulvous ; 

 basal region deeper; disc not so red as in the other Graptas. Fringe 

 white in % , except at tips of uervules, where it is brown ; in 9 , white 

 in some of the interspaces, and brown interspersed with white in others. 

 Posterior border, with a narrow subuiarginal band of fulvous, preceded 

 by a connected series of dark brown crescents rather obscurely defined. 

 'J'he row of triangular spots anterioi" to these, a shade lighter than the 

 disc, with the two next the tip, edged before with blaeic. The seven 

 discal spots are of a less glossy black than in inferrogatiouix. 



Serondaries. — Tail straight, short, not exceeding three-fourths the 

 length of that of interrogationis, which it equals in breadth; length in 

 S , one-half greater than in 9 • Above, the disc is purplish black, 

 shading into dark fulvous at the base and at the interior margin. The 

 black spot between the subcostal uervules is not so conspicuous as those 

 of the primaries; that between it and the costal nerve. Indistinct or 

 wholly wanting; that lying partly within the discoidal cell and extend- 

 ing over the lower nervule of the submedian (which spot is oblong and 

 cpiite distinct in interrogationis) is small, sometimes geminate, or re- 

 duced to a simple dot ; in lieu of the conspicuous triangular black spot 

 at the bifurcation of the submedian in interrogation is, is an obscure 

 shade resting on the upper nervule and above it, and extending nearly 

 to the subcostal nervule. The submarginal row of red crescents which 

 characterizes interrogationis, is here obsolete or limited to three round- 

 ed spots at the most between the nervules of the subcostal. Tail and 

 tips of nervules with lilac scales; in interrogationis the entire hind mar- 

 gin is bordered with lilac. 



Beneath in interrogationis, a marked feature is the series of yellow 

 or whitish spots of the primaries, usually eleven in number, nearly 

 square, placed on the basal third of the marginal nervure, joining which 

 and extending to the costal nervure are groups of darker colored yellow 

 scales irregular in outline, but grouped opposite to the above costal spots. 

 In this species, the costal spots are fewer in number, smaller, elongated, 

 occupy but the basal fourth of the costa, and are not so conspicuous as 

 to be a prominent feature; the contiguous yellow scales are not grouped.
