Head black. Fack and jialpi silvery. Antenn;e dark fuscous, be- 

 fore the apex white. Anterior wings oHvaceous-fi(scotis, wnth a slender, 

 short, silvery basal streak, and three short costal streaks and three dor-

A single specimen, taken by ]\[r. Scott in the beginning of 

 July, near llenfrcw, amongst birches. ^Ir. Scott, with the view 

 that the information to be derived from the sight of the uni([uc 

 specimens of this and the preceding species, might be more 

 widely disseminated than if tluiy remained in his own collection, 

 has with extreme liberality placed them in mine.
