streak is attached the lonji? claviform, which extends beyond the middle of the 

 wing, is somewhat paler in color, and defined hy a very narrow hlack line Avhich is 

 usually incomplete. The ordinary spots are confluent, together irregularly gourd- 

 shaped, interiorly well defined l)y dark shadings, superiorly indefinite ; the orbicular 

 is paler than the ground, with a faint yUow tinge; the reniform is dusky centered. 

 The s. t. line is marked by a smoky or blackish shade, interrupted beh)w the apex, 

 which may bo either even and continuous, or invade and darken the terminal space, 

 or may send in a spur over vein 5 to the lower e<lge of the reniform, joining the 

 dusky shading beneath that spot. A very narrow dusky terminal line; the fringes 

 white. Secondaries white, immaculate. Beneath white, the primaries with a dusky

Three specimens, 1 male, 2 females, are before me, no two exactly alike, and yet 

 resembling each other closely. The species is unlike any other which has been re- 

 ferred to Peridroma, in the color and in the strigate character of its markings; l)ut

 ciliated. The tibial armature on all legs is feeble, and that of the anterior pair is 

 scarcely more developed.
