diffuse and discontinued just before the costa. Subterminal line dark 

 yellowish, distinct, undulate, bi-toothed between the first and second 

 inferior veins, terminal space faintly metallic with a distinct, nar- 

 row, terminal pale rose-colored band. Posterior wings silky, blackish ; 

 fringes pale ochraceous. Under surface of anterior wings pale ochra- 

 ceous, with two transverse blackish bauds and diseal spot absorbed in 

 the blackish color of the disc. Under surface of posterior wings pale 

 ochi-aceous with two blackish bands, outer one diffuse, and a diseal 

 lunule. Thorax honey yellow, carneous posteriorily and on the tegula3; 

 abdomen with three slightly ferruginous crests. S and 9. Esp. I2 

 inches. Coll. Eut. Soc. Philadelphia. 



Not uncommon throughout the Middle and Eastern States. 



Closely allied to P. xrea Hiibner, from which it constantly differs 

 by its somewhat larger expanse, the larger median space, the straight 

 distinct median lines, the transverse posterior line succeeded by a me- 

 tallic baud and by the presence of a second diseal spot on the anterior 

 wings. Many S $ individuals from Mass., N. Y., Penn., which I 

 have before me are constant in these and other more trifling differ- 

 ences from P. serea. I believe to cite here M. Gruenees " A," which 

 that Entomologist refers as a variety to P. serea on account of an in- 

 termediate individual which he has seen from Florida. Nevertheless 

 I believe with a sufficient number of perfectly coinciding specimens of 

 both species to correctly separate the present under a distinct specific 

 name.
