NOCTUA CYNICA Smith, var. PERUMBROSA Dyar. 



One hundred and seventeen specimens, July 21, 25, 27, August 5, 

 6, 7, 11. This is like the Eastern riihifera Grote and cynica Smith, but 

 darker in color. Whether there are two species mixed, diflfering onl}^ 

 in genitalia, as Smith claims to be the case with the Eastern forms, I 

 do not know, as all those examined agreed with the figure of cynica. 

 Some of the specimens run close to the obscure form of I'osaria. We 

 did not obtain the larva on account of the lateness of appearance of 

 the moths.
