 no crenuister, though the hirva spins a tough cocoon of dirty gray silk, stuck over with fine

 L. camelina? L. cuculla and cameUna are closely related in structure and coloration. 1 have 

 not a specimen o{ cannclifa to examine.)

Moth. — Two c? , one 9 . Head and thorax mouse color, the head, and the breast directly under 

 the former, darker than the thorax above; thorax behind the scutum edged with silvery white 

 S'^ales, w^hile the teguhe are edged with brown scales. Fore wings of a uniform pale vandyke 

 brown, darker on the costal region than on the outer margin, the limits extending between the apex 

 and the middle of the inner edge. Veins and their branches darker than the rest of the wing. 

 There are no cross lines. Four reddish brown streaks on the outer fourth of the costa, one ending- 

 very near the apex; a large one in the fourth subcostal intersi^ace, and a smaller, very narrow 

 streak in the Hfth subcostal interspace. 



The distinctive mark is the conspicuous silvery white stripe shaded with brown in front, 

 beginning at the base of the wing at the origin of the subcostal and cubital veins and extending 

 along the internal vein to its basal third, not reaching a point opposite the tuft. The latter is 

 small, subacute, and consists of pale ocherous and brown scales. Hind wings pale ocherous, dusky 

 at the inner angle, which is full and ijrominent, and brown in tint. There is no line on the wing. 

 At the base of the pale fringe in both wings is a distinct scalloped brown line. Underneath, the 

 fore wings are pale mouse-gray; the hind wings mouse color on the costal region, while the rest 

 of the wing is whitish ocherous with no spots or lines. 



Expanse of wings, S , 50 mm.; 9 , 57 mm.; length of body, 3 , 20 mm.; 9 , 2J: mm. 



Mr. Edwards's Colorado specimens do not essentially difi'er from Maine examides. 



This is an exceedingly richly colored moth, and ea.sily recognized by its mouscbrown hue and 

 the conspicuous but silvery white shade on the base of the fore wings. ,The Colorado examples 

 are frosty ash rather than reddish brown, as Eastern si^ecimens are.

Moth.—-^ S . Eyes hairy; antenna- short, with long pencils of bristly hair from each joint. 

 Primaries with uneven external margin. Bright brown in color, allied to camelina, but less rusty 

 or reddish. Nervules interruptedly marked in very dark brown. Transverse anterior line single, 

 forming two approximate obtuse teetii on the cell, deut.ite below cubital vein. Transverse-
