Dr. Butler tells us he has received the true D. exanthemata from 



Canada. D. falcataria, D. carnearia and perpallidaria are probably 



conspecific. The species of the genus differ in appearance, but agree 



in structure. 



D. borealis n. sp. — Expands 25 mm. Palpi whitish at base, blackish at 

 ends; front blackish gray; antennae gray, ringed with black; thorax blackish 

 gray. Abdomen whitish, thickly irrorated with black atoms. Wings light gray, 

 thickly and evenly spattered with blackish scales to beyond cell, then somewhat 

 darkened into an even, broad, indistinct line, followed by a lighter band of about 

 the same width, then darker again to outer margin, the wings here being washed 

 with fuscous, and all wings having a general dull gray appearance, darker at 

 outer line and on outer spaces; beneath gray with black atoms, but not so much
