niatgin. Mesial s|)ace broad, lijihl ash as in autumnalis, with faint linear 

 discal dot, but heavily stained with reddish in central portion, and the 

 whole space somewhat shaded. I'xtradiscal line black, shaded with red 

 externally. Fifth or internmrginal band as in autumnalis, sinuate, 

 smoke, outer margin greenish gray, venular sjjfts at base of 

 fringe. Hind wings as in autumnalis, with two smoky bands. 

 Beneath lines show through fainily and a slight rose colour to mesial 

 space. This is a very striking variety, and closely resembles Calif orniata 

 Pack, which 1 believe is a local red race of autumnalis. It differs, however, 

 as follows : the basal band in Californiata runs almost straight across to 

 inner margin, in perfiacta outward from costa, then in a scallop to inner 

 margin. Mesial band of Californiata is reddish on each side of the second 

 band, as is also the basal space ; this is not true of perfracta. Third line 

 oi perfracta is black |)att way, then red to inner margin; in Californiata 

 entirely black; also the mesial space is not so red, and the fifth line is shaded 

 wiili red only uiternally in perfracta, and not externally also as in 

 Californiata. Gucnce, in his description of pluviata (Hist. Nat. Ins, 

 Spec. Gen. Lepid., Vol. XI, p. 378, 1857), speaks of this variety, but does 

 not give it a naiiic. My specimen is a beautiful fresh one, and showi the 

 markings clearly, and was given to me by Mr. R. K. Pearsall.

Kxi)anse, 30-35 mm. Pnlpi short; head gray at base of antenna?; thorax 

 gray, reddish tinted; body gray, marked with black dorsally; fore wings ash 

 gray, with red shadings; except the mesial si)ace, which is ash gray. Next 

 to body a slight blac k dash on costa, basal space ash, with a slight tinge of 

 red ; basal line black and wider than usual, running to median vein in an 

 outward curve, thence almost straight to inner margin. Mesial band much 

 suffused with red, so that it is difTicult to see the second irregular band. 

 Third line black and narrow, running almost straight across wing except 

 for slight notches on the vtins. Mesial space light ash, discal spot linear. 

 Petween veins 2 and 3 there seems to be a tendency for the third and 

 extradiscal lines to unite, as the mesial band narrows there, and there are 

 black streaks on the veins connecting the two. Hxtradiscal or fourth line 

 black and irregular, connecting in most cases with third line by bl.ick dash 

 at vein 3. Pcyond extradiscal line the margin is brownish red, with the 

 usual wavy inter marginal band. X'enular spots at base of fringe. Hind 

 wings pale ash, with two dusky bands near outer margin. Heneath lines
