THE CANADIAN ENTOMOLOGIST. 225 



Spun up June 3rd, among leaves. Length of pupa, nine-tenths of an 

 inch ; width, five-twentieths. 



Colour, pale reddish, with a thin whitish bloom. 



Gave imago June 24th. 



The larvae of this species is rarely found except hidden under the 

 loose scales of bark on the trunks of hickory trees. Later the imago may 

 often be found also hidden under bark. 



Like many Catocalse, it is quite common some years, but such a 

 season may be followed by years of scarcity. 



It appears to be but little subject to variation. We have not seen 

 the form miranda, Hy. Edw., here, and would like to correspond with 

 any one who takes it.
