separating the two. In P. angulalis the male antennal joints are raoder- 

 atelv long, not marked when denuded, and only slightly so when clothed 

 with scales, with moderate slender lateral bristles, and quite a dense 

 frin-ing of shorter cilia beneath; each arising from a small tubercle 

 or sensory pit. The female palpi are also longer. /'. asopuihs has the 

 antennal 'joints in the male shorter, more marked, the lateral bristles 

 lon-er and stouter; but the ciliations from sensory pittmgs much 

 reduced in number. The palpi of the female are somewhat shorter, 

 but the terminal joint is longer and very much broader; altogether 

 more largely developed. . 



The species are commou and are coincident m range, covering the 

 entire Eastern and Central United States, extending uortli well into 

 Canada and r.outhwesterly into Texas.

 Ground color varying from yellowish or rusty red brown to purplish. 

 Head and thorax concolorous, abdomen paler, less brown. Primaries 

 with the markings distinct and contrasting. Transverse anterior Ime 

 slender, single, a little oblique inwardly, but outwardly convex. Trans- 

 verse posterior line slender, single, brown, rather evenly bisinuate. 

 Subterminal line rarely complete, pale, rather even except at about mid- 

 dle, where it is best marked and forms a small W, which m none ot the 

 specimens seen by me crosses the terminal space. A brown, continuous 

 terminal line. There is a broad oblique median shade which is some- 

 what vague and indefinite from the costa to the median vein tliere 

 becomes a rich velvety brown, sharply detined inwardly bu diffuse 

 outwardlv, broadest on the internal margin. Orbicular sma 1, yellow 

 or brown; or entirely wanting. IJeniform oblong, obli<iue, r.ch velvety 

 brown in color, with a concolorous central line. Along the costa 

 before the apex is usually a richer brown shade, below which on the 

 outer margin is a somewhat lunate yellow patch, varying somewhat in 

 prominence, and this in turn is .nferiorly followed in the terminal 

 space by a somewhat darker shading whi.-h is sometimes little marked.
