 laricaria, Stn. — Expanse 1| to If inch; second generation 

 l|to H- inch. Body slender; wings ample, white, brownish- 

 white, or greyish-white, dusted more or less with smoky- 

 brown or smoky-grey ; beyond the middle of each are two 

 rippled slender black transverse lines, often attended by an 

 outer brown parallel shade. 



Antennas of the male distinctly ciliated with fine tufts of 

 delicate bristles sufficiently long to furnish the appearance of 

 fine pectinations, light brown ; palpi whitish-brown ; face 

 white, smooth, edged above by a deep channel and beneath

 nervures. This line is edged outwardly by a yellow-brown 

 stripe, sometimes hardly distinguishable, but containing, 

 almost always, in the middle, a somewhat squared or angu-

 first and second lines is a curved cloudy-brown central shade, 

 arising, as do the two lines, each from a blacker cloud on the 

 costa ; discal spot rarely perceptible ; beyond the second line 

 and its attendant brown shade is an additional black-brown 

 line or series of clouds in pairs, often black -tipped ; closely
