in<^ a point nearer the apex than tli(! similar line in other species, whence it 

 bends nearly at right angles on the eiosta ; it is tawny-brown, edged on each 

 side with yellowish, witli n dark external shade, which stops at the l)end; the 

 extreme costnl portion of tlic line being brown, anil as if made np of a row 

 of closely-connecled beads. A small, transversely ovate, discal dot. No 

 middle line. A faint niiirglnal row of dots on l)otli wings. Hind wings 

 scarcely paler than tlic anterior pair, with a liunt discnil dot and a'single dusky 

 brown line, which is distinctly bent opposite the discal dot, and terminates 

 on the costa. Under side of both wings as usual in the genus, being gray, 

 mottled with whitish, and on the costal regions of both wings mottled with 

 ochreous; the veins also speckled with ochreous. Legs as usual, and concol- 

 orous with the body. 



Length of l)ody, S. 0.47; of lore wing, J, 0.55; expanse ol" wings, 1.00 

 inch.

This pretty species ditlers from any others I have seen by the curved 

 outer line reaching much nearer tlie apex and there becoming bent at a con- 

 siderable angle, and oidy the Ijrown ])ortion of the line continued On to tlie 

 costa. Mr. Grote d^escribes in his female specimen a taint median line on 

 the fore wings, and a iiVmt submarginal line "appearing as a vague festooning", 

 and a- single line on the hind wing distinctly bent oi)posite the discal dot. 



The example Ironi ]\Iissonri has the markings of the New York speci- 

 mens, but the extradiscal line ends liulher trom the apex than usual, the line 

 behind ))eing a little less ob]i(pie. The wings are also darker, and of exactly 

 tiie shade of P. tyijdsciatd, to which the Missouri specimen shows a slight 

 tendency to approximate; the under side of the wings in the Missouri 

 example being scarcely distinguishable from that of P. trifasciata.

1 S. — Tills species dix^s not difier structurally from the others ol the 

 genus, except that the apex of the lore wings is periiaps slightly mor<^ rouiuh'd. 

 Hind wings and legs as in the other species. Body and wings dee|) mouse- 

 gray. Fore wings with the l)asal yellowish line straight. The median dusky- 

 ash line rather dilfuse, straight, and inclosing the distinct discal ringlet. 

 The outer line almost straight, being very slightly sinuous, tawny-yellow; the
