MAMESTRA NEVAD^E Grote. 



Six specimens, July 1, -I, 19, 21, August 11. The specimens agree 

 with some from Wisconsin which Prof essor Smith has picked out from 

 the U. S. National Museum series as representing his <((n<((1(iii<is. I 

 think, however, that I really have nevadx (xrote, described from the 

 Sierra Nevada of California, or, as is more probable, canadenHh is a 

 synonvm of nevadsp. Mr. F. H. Wolley Dod has sent me specimens 

 from Calgary, Alberta, labelled nerads', which seem conspecitic \\ith 

 the Kaslo ones.
