232 THE CANADIAN ENTOMOLOGIST 



Hadena devastatrix Brace. A few of this species stood under 

 their correct name, but a number far greater did duty for versiita 

 Smith. 



Hadena arctica Bdn. 



Hadena occidens Grt., mixed in the series with arctica. 



Iladena miniota Sm. A few specimens, including two female 

 co-types. I haye elsewhere expressed my conyiction that miniota 

 was a bronze-coloured form of versuta, but recent examination of 

 the genitalia of a large number of colour forms of Calgary males 

 has disclosed strong evidence of the existence of two species, not 

 always separable on superficial characters. One unfortunate result 

 of this discovery is that the exact identity of versuta must at 

 present remain in doubt. It is quite probable that older names 

 properly belong to both species. 



Iladena cariosa Gn. Two specimens. 



Hadena commoda Walk. (syn. alberta Sm.) Only two specimens 

 stood under their correct name, but numerous others were found 

 mixed with other species. Four specimens stood as cogitata Sm. 

 as well as one small specimen of lateritia, in truth most surprisingly 

 like commoda. 



Iladena lignicolor Gn. 



Iladena inordinata Morr. One specimen, standing as semi- 

 lunata Grt., the distinctness of which is doubtful. 



Iladena mactata Sm., including the grey form allecto Sm. A 

 female specimen of a probable variation of this species stood, 

 quite wrongly, under adnixa Grt. 



Hadena modica Gn. 



Hadena semicana Walk. (syn. hausta Grt.) One specimen, 

 mixed in the series with exhausta Sm. Standing as semicana was a 

 single badly worn specimen of Parastichtis discivaria Walk. Smith 

 always had an entirely wrong conception of semicana, and used to 

 give this name to pale specimens of fractilinea, from which it is 

 widely distinct. 



Hadena exhausta Sm. A series of very poor specimens.
