360 THE BUTTERFLIES OF Till-: 



larger and a little out of line; spot- !> ami 10 arc united 

 into an hour-glass-shaped spot. Spots 1 to 5 arc nar- 

 rowly ellipsoidal, 6 to 8 are somewhat truncated inter- 

 nally, all the others are strongly pointed internally. Be- 

 tween these two bands the spat* in the end of the eell 

 and between the median and submedian veins is lighter 

 and more reddish brown than the rest of the wing. Be- 

 tween the submarginal band and the margin is a series 

 of roundish brown spots, each tipped externally with a 

 gray crescentic spot resting on a terminal brown line. 



Hind wings more of a reddish brown than the fore 

 wings, with two rows of indistinct ochraceous spots near 

 the outer margin, and a spot at the end of the cell. The 

 males are darker brown than the females, and for that 

 reason the bands are more obscure. 



Under side of the female grayish brown, the apical 

 portion of the fore wings gray ; the white hyaline spots 

 are repeated, and both wings have two marginal rows 

 of whitish spots. The males, as above, are darker than 

 the females. 



According to Mr. S. H. Scudder, the larva feeds on 

 willow, poplar, and Lespedeza capitata. The butterflies 

 are to be seen in June.

Fore wings above pale umber-brown, with grayish 

 scales sprinkled over most of the surface (more diflftised 

 than in the other species), except on the fuscous bands, 

 showing especially beyond the submarginal band. There
