Anterior wings deep velvety black, all the veins diffusely striped 

 with flesh color. From the base of the wing, below median vein, a 

 broad flesh-colored band runs to external margin, becoming distinctly 

 furcate above internal angle, and upon which, in the terminal half of 

 the wing, rests a series of identically colored bands resembling the let- 

 ter K with the straight stroke turned towards the base of the wing and 

 bent, and the upper limb attaining the external margin below the apex, 

 reflexed to costa ; a straight broad stripe crosses the disc from costa to 

 median vein, sometimes apparent in the interspace below the latter. 

 Posterior wings red of a more or less pinkish shade, with a terminal 

 series of black spots margined with buff", becoming fused at costal angle, 

 the one above anal angle of uncertain size in either sex, discal and sub- 

 costal spots usually present, besides which along costal margin in some 

 specimens of either sex are black shade streaks, terminating in one or 

 two accessory spots. Tegulse and thorax black margined with flesh 

 color, two black spots on prothorax making five thoracic black macula- 

 tions. Head, above the eyes, flesh color, immaculate; palpi, under 

 surface of thorax and legs, smoky black, latter touched with yellowish 

 on anterior femora and tibiae in the % , posterior tibiae generally streaked 

 with whitish in either sex ; under surface of abdomen black, marked 

 with whitish at the base of the segments in the % . Antennae pecti- 

 nate, smoky brown in the % , darker, simple in the female. Exp. 1.08 

 to 2.05 inches. (Coll. Ent. Soc. Phil.) 



Ilab. Both Canadas, and occurring throughout the Eastern, West- 

 ern and Southern States. 



The coloration of the stripes on anterior wings is subject to variation 

 from pale flesh color to yellowish. I have seen very large specimens 

 of this species expanding upwards of 3 inches and in which the spots 

 on the posterior wings were largely developed, but I cannot separate
