AMERICAN LEPIDOPTERA. 373 



Grapta Oreas, n. sp. 



Form of Faunus. Primaries deeply incised and emarginated; sec- 

 ondaries with a prominent rounded tail and a second shorter between 

 this and anal angle. 



il/a/e. Expands 1.5 inch. Upper side deep red fulvous, color of 

 Faunus, spotted with black. Primaries have a black-brown border on 

 which rests a series of rather large yellowish lunules ; a yellowish sub- 

 apical patch beyond which is another of red-brown connecting costa 

 with hind margin; a dark elongated patch from costa covers the arc . 

 in cell two rounded spots and three at right angles to these, on the 

 disk, as in Faunus ; near inner angle a red-brown patch. 



Secondaries have the border diffuse, enclosing a row of yellowish 

 lunules; a black patch on costa and two on disk; fringes dark brown, 

 yellow in the emarginations. 



Under side very like Frogne, in color dark brown, varied with shades 

 of paler brown or black, slightly grey near apex ; the whole surface 

 covered with fine, abbreviated streaks of darker color ; the basal space 

 scarcely darker than disk and but partially limited on outer edge by a 

 black line; in cell of primaries two elongated dark spots; an extra 

 discal common row of black points; in the incision of primaries and 

 along hind margin of secondaries faint traces of lunules such as charac- 

 terise the allied species ; silver spots small, narrow, bent at right angle 

 and pointed at either end. 



Body brown-fulvous; palpi black below, buflf on sides, fulvous above ; 

 antennae brown ; club brown, tip ferruginous. 



California, from Dr. Belir. 



This species seems to me sufficiently distinct from our eastern Grap- 

 tas. It connects the two groups, having the form of i^owHws and the un- 

 der surface of Frogne. Under the name C-albiim, Dr. Behr, in his paper 

 on Californian Lepidoptera, No. IV (Cal. Acad. Nat. Sci., 1864), des- 

 cribes the larva as having "a dimidiate coloration, like that of the Eu- 

 ropean t?-rt/6«)»,, the "forepart being white, the abdominal part yellow," 

 and as feeding on Urtica. I only know the larva of C-album from pub- 

 lished descriptions. Westwood, in Humphrey's Brit. But., says it is 

 " red in front with the hinder part white" and the figure given corres- 

 ponds. Chenu, p. 91.), says it is " reddish-brown with a white dorsal 

 band not covering the four anterior segments, which are sometimes 

 yellow." By which it would appear that although the coloring of the 

 Californian species is '-dimidiate," there is a difference between it and 

 C-alhnm.
