men slender, acutely conical at tip. Body brown-ash (sometimes quite pale). 

 Fore wings pale-ash ; base of wing dark, especially toward the basal line, 

 whicii is curved outward in its general course; it is very zigzag, with a sharp 

 tooth projecting outward just behind the costal edge, a much larger, shar]), 

 jagged tooth in the discal space ; just below the median vein is a smaller, 

 blunter tootii ; the line sends an angle inward on the internal vein, being 

 directed outwaid, where it ends on the inner edge; beyond is a broad, distinct, 

 russet-brown l)an(l, vai'ying in width and curved outward in its general course 

 (the brown shade is olten wanting, and the Ixuid is concolorous with the rest 

 of the wing); the outer edge of the band is very zigzag, there being an acute 

 tof)th al)ove and just below tlie subcostal vein, and another large tooth in the 

 suljUicdian space ; it is bent outward on the inner edge ; tlie outer edge of 

 this brown band forms the inner edgt; of tlie broad median band, which is 

 paler in the middle, concolorous with the rest of the wing, and with two 

 central lines, converging as usual below the median vein, and forming three 

 ringlets; on the sides, the band is blackish, especially so on the front half ol" 

 the outer edge, wiiere it forms a broad, oblong, black patch. Discal dot 

 usually distinct; the outer edge of the l^and sends a broad jagged projection 

 along the tirst median venule, the distance from the point to the edge of the 

 wing being a little greater than tlie thickness of the thorax; from the costa 

 to this point, the line is directed more or less, usually very, oblicjuely out- 

 ward ; just below tiie subcostal vein is a sharp sinus, followed i)y an acute 

 angle on the independent venule; in the discal and first median spaces, each, 

 is a large tooth, the lower one narrower, and both much smaller, and forming 

 a more pointed projection tiian in P. pninata ; below this projection, the 

 line retreats either very obliquely, witjjout niucli of a curve inward, or witli a 

 decided curve ; the line is usually scalloped; a long scallop in the second 

 median space, l)ut not projecting beyond the base of the scallop in front of 

 it ; tile line is edged externally with white. Beyond the median band is a 

 broad, distinct, russet-brown band, when oI)Solete leaving a large, subapical, 

 brown patch (sometimes tlie Ijrown band is entirely wanting); a submar- 

 ginal, zigzag, white line, the angh's smaller, less distinct, than in P. prunata; 

 the whit(! points are succeeded by a inarginal row of black triangular points; 

 a distinct, oblicpie, black, apiral line, with no dark cloud lielow as m prunatti
