small, pule yellow, almost white; the patches at apex and inner angle 

 of primaries fuscous; the other markings black, arranged as in Siienus 

 and otiier allied species; the two spots in cell of primaries often con- 

 fluent, and all large; the fringes fuscous, white in the euiarginations. 



Under side mottled in shades of brown and greenish-gray, with a 

 vinous tint over the basal area and disk; this area, limited by an 

 irregular common band, which is sharply defined exteriorly and edged 

 nearly throughout by a black line; on the inner side it is well-de- 

 fined next the costal and inner margins of secondaries and is also etlged 

 with black ; on the submedian interspace of secondaries this band pro- 

 jects a narrow spur to the inner margin just above the angle, and on 

 the posterior side of this spur is a double sinus, all edged by black ; 

 the extra-discal space greenish-gray, mottled with pale brown and 

 gray-white; a clear patch of the same gray on costal margin; the 

 margin at the incision and the anterior part of the margin of second- 

 aries olivo-brown ; the transverse spots on extra-discal area large, espe- 

 cially on the posterior half of each wing, olive-brown on a gray white 

 ground ; the submarginal lines olive-brown narrowly edged with black, 

 and on primaries preceded by a conspicuous wavy stripe of black ; the 

 silver mark- an angular open C, barbed roughly at the upper end, the 

 lower end thickened and blunt, the two arms of equal length. 



Female. — Same size. Similar to the male; the submarginal lunules 

 more decidedly white; beneath similarly colored and mottled; on the 

 posterior part of secondaries the extra-discal spots are joined to the 

 submarginal lunules by gray patches; the silver mark delicate, the 

 lower limb abbreviated. 



Body above fulvous; beneath gray-brown; the thorax vinous; legs 

 gray-brown; palpi light gray, with a few brown hairs interspersed, 

 brown at tip; antenna; fuscous above, fulvous beneath; club black, 

 tip ferruginous.

 (yaliforiiia. and on Vancouver's Island. 



Grapta Silvius, n. sp. 



Male. — Expands 1.9 inch. Hind margins deeply incised, strongly 

 dentated ; outer angle of secondaries much produced; tail broad, 

 rounded; a prominent dentation midway between the tail and inner 

 angle. 



I'ppcr side yellow-fulvous, bright red on the disks; both wings 

 bordered by ferruginous-brown, narrowly on primaries, broadly on 

 secondaries, and dusted throughout on the marginal edge by yellow
