This is a common and widely-difTused 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 marking.s, c.s])ecially 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 bcdow the median vein. 

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

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

 considerably; but the species 4s very distinct from any other of the genus, 

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

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