white ; the base of the lure wings dark, bound beyond by a w hite line, which 

 is succeeded by a broader dark band; between this and the median dark 



hand is a while band varying in width ; this band traversed by a dusky line 

 the median band and its diseal dot is much as in lacustrata, but there is apt 

 to be a deeided sinus above the point on the median band: beyond this band 

 is a broad, clear, white band, very well marked, and common to both wings; 

 it is this (dear, conspicuous band which separates this species from lacustrata; 

 this band contains a dusky line ; the margin of the wing is dark, traversed by 

 the usual scalloped line. Hind wings dusky on the basal half, with a distinct 

 diseal dot ; the broad white band is situated half-way between the diseal dot 

 and the edge of the wing, which is dusky, and traversed by a wavy white line. 



Length of body, <?, 0.40, 9,0.36; of fore wing, S, 0.50, ?, 0.50; expanse 

 of wings, 1.05 inches.

There is no difference between eastern and Pacific-coast examples, nor 

 can I see any difference in size or markings from European examples received 

 from Professor Zeller. 



The range of this species in the Old World is, according to Staudinger, 

 as follows: Northern Germany; Northern England (including Scotland); 

 Belgium; I Southern France; ? Switzerland ; Galicia: Finland; St. Peters- 

 burg; Southern and Western Russia; Amur. 



Larva. — "The caterpillar is stout, rather attenuated at both ends, and 

 rests with the head tucked in, the anterior part of the body, when disturbed, 

 being curled in, or curved in the manner of the Ionic volute ; the head is 

 brown, beautifully dotted and marked with black; the body is smoky-brown, 

 delicately mottled and varied; the back may be said to have seven smoke- 

 colored stripes, alternating with paler stripes; the medio-dorsal stripe is not 

 perceptible on either the second or thirteenth segments, but is distinct and 

 uninterrupted on the third, fourth, fifth, sixth, seventh, and eighth segments; 

 it is suddenly dilated anteriorly, and more gradually posteriorly, and is 

 extremely attenuated and scarcely perceptible on the remaining segments; 

 on each of the interstices bit ween the segments, commencing between the 

 fourth and fifth, is a short, transverse, reddish band, terminated at each
