diffuse, shorter, submarginal, dark-brown, zigzag line, with a slight violet 

 tinge; the space between this and the wing suffused with violet-brown, 

 extending only toward the middle of the wing, or sometimes passing beyond 

 toward the apex. Beneath, the wings are yellow ochreous, speckled, espe- 

 cially on the hind pair, with coarse, violet-brown specks. Fore wings clear 

 when covering the hind ones, with three costal spots, the third in the middle 

 of the costa ; beyond, the angulated outer line is reproduced; apical, oblique 

 line distinct, with a violet-brown cloud below. Hind wings with three regu- 

 larly-scalloped lines; the margin of the wing broadly clouded with violet- 

 brown. Legs yellow; joints lipped with violet-brown. Abdomen yellow, 

 tinged above with rust-brown.

This is a common and widely-diffused species, ranging from Southern 

 Maine to Texas, but has not yet occurred west of the Mississippi River. 

 It flies during July and August, entering houses and settling on the walls, 

 resting with its abdomen curved grotesquely over its back. It varies much 

 in size and considerably in its markings, especially in the extent of the violet- 

 brown markings ; the middle of the wing is, however, often clear, and, when 

 so, the two inner lines appear, forming large ringlets below the median vein. 

 The margin of both wings is sometimes clear ochreous-yellow, except on the 

 internal angle of the hind wings. The distance between the lines varies 

 considerably ; but the species is very distinct from any ol-her of the genus, 

 and may at once be recognized by the dark, clear lines, the extradiscal one 

 forming a large, conspicuous, falcate angle in the middle of the wing; also,
