North American Tortricida. 137 



Padisca caniceps, n. s. (PL IV., fig. 9). 

 Palpi white, the apical joint short, almost concealed by the 

 closely-projecting scales of the 2nd joint. Head thickly clothed, 

 hoary white, with projecting frontal tuft. Antennae shghtly 

 pubescent, white. Thorax white, tinged with pale reddish fawn- 

 colour. Fore wings (with the costa straight, apical margin oblique, 

 dorsal margin convex towards the base) reddish fawn-colour, 

 sprinkled with hoary white scales, especially above the middle of 

 the wing and towards the apical margin. The costa beyond the 

 costal fold white ; fringes white ; a silvery white line, slightly 

 dilated before its depressed and pointed apex, follows the fold from 

 the base, and terminates beyond the middle of the wing, not 

 reaching the dorsal margin. There are three shorter and less 

 conspicuous silvery white streaks, one along the basal half of 

 vein 4, one (very short j at the upper angle of the cell, and almost 

 reaching to this ; another following the course of vein 8, from the 

 costa immediately before the apex. Abdomen and hind wings 

 shining whitish, faintly tinged with pale fawn-colour. The fringes 

 white; on the under side the fore wings are tinged with fawn- 

 colour; the costa white. Hind wings white, tinged with fawn- 

 colour towards their costal margin. Expanse, 28 mm. 



One male. Montana. 



Padisca emaciatana, n. s. (PI. IV., fig. 7). 



Palpi white, tinged with fuscous at the sides. Head, thorax, and 

 antennae white. Fore wings elongate, narrow at the base, with 

 the costa straight; apical margin very obHque, white sprinkled 

 with fawn-coloiired scales ; an oblique fawn-coloured patch about 

 the basal third of the wing, containing a few dark umbreous scales, 

 followed by a wider patch of the same colour beyond the middle, 

 partially connected by an obliquely receding shade with the middle 

 of the costa, and by a similar shade to a point beyond the middle 

 of the dorsal margin. There are about six small fawn-coloured 

 costal spots and a more conspicuous patch of the same colour at 

 the apex of the wing, all containing a few umbreous scales. Cilia 

 white, sprinkled with fawn-colour. Hind wings fawn-gi-ey, with 

 a rather iridescent opaline hue, and a dull line along the base of 

 the whiter fringes. Expanse, 22 mm. 



Three males. Arizona. 



This species reminds one much of P. larana, Wlsm., 

 but is somewhat more distinctly marked with fawn- 

 colour ; the fore wings are narrower in proportion to 

 their length, especially at the base, and the apical margin
