streak is attached the long claviform, which extends beyond the middle of the 

 wing, is somewhat paler in color, and detined by a very narrow black line which is 

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

 shaped, inf eriorly well defined by dark shadings, superiorly indefinite ; the orbicular 

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

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

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

 or may send in a spur over veiu 5 to the lower edge of the reniform, joining the 

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

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

 shading in the disk. 



Expands 27-31'""i; 1.10-1.24 inches.

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; but 

 it agrees with the structural characters of the genus and has the pointed wings of 

 the saucia group. The antennte of the male have the joints slightly marked and 

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

 scarcely more developed.
