moderate, larp:er superiorly, a little contracted at the middle, pale ringed, of the 

 pale costal shade, except inferiorly, where it is brown shaded. The pale outward 

 tooth of the t. a. line at first sight resembles a claviform spot, Beneath pow- 

 dery, disc of primaries blackish, costal and terminal region reddish gray ; second- 

 aries with a smoky extra median line; all wings with a smoky discal spot. 

 Expands 34-42 mm. = 1.36-1.68 inches.

Six males and seven females are at hand and vary only in the 

 aincnint of contrast between the costal and central portions of the 

 wing. The ordinary spots are extensions of the pale costal space 

 and are usually well relieved. 



In the males the antennal joints are ciliated, and the basal third 

 is a little thickened by black scales on the inner side.

 Head, thorax and primaries reddish gray, streaked and shaded with rusty 

 brown, sparingly powdered with black. Abdomen paler, uniform, the dorsal 

 tuftings well marked, that on tlie third segment prominent. Secondaries smoky, 

 with a yellowish tint, the fringe smoky. Head with a brown line below the 

 usual tufts, or entirely brown. Collar with a black line, above which it is gray 

 tipped at the base of the well-marked divided crest. Patagise powdered and 

 marked with gray, and with a gray patch at base of primaries. Primaries with 

 the markings incomplete, tending to appear strigate, the veins being darker 

 brown. A slender, longitudinal black line at base. Basal line geminate, brown, 

 very oblique across the costal paler space. T. a. line brown, geminate, veiy 

 strongly dentate in the interspaces, marked by small, black venular dots. T. p. 

 line marked by geminate, black venular dots, except in the submedian inter- 

 space, where the usual blackish patch connects the two lines. S. t. line of the 

 ground color, narrow, irregular, not well or completely defined, preceded by 

 small, rusty brown spots, best marked opposite the anal angle and the cell, an 

 oblique smoky shade extending through the terminal space at these points. 

 There is a series of small, black, terminal lunules in the interspaces, and of small 

 black dots on the veins. Median shade usually distinct across the costal space 

 and oblique between the ordinary spots, sometimes suffusing the space between 

 median lines at the middle, and narrow, indefinite, below that point. The or- 

 bicular is long, oblong, oblique, narrowly outlined in brown and often attached 

 to or connected with the reuiform. The latter is large, a little paler or annulate 

 with paler, not outlined, a little enlarged above. Beneath reddish, powdery, 

 disc of the primaries darker ; secondaries with a complete, primaries with an 

 incomplete outer dusky line ; all wings with a large discal spot. 

 Expands 37-43 mm. = 1.48-1.72 inches.
