SMITH, NEW NOCTUID^ 109 



T.a. line oblique, outcurved in the interspaces . . . richardsoni 

 T.a. line angulated on the median vein, then rigidly 



oblique to inner margin lanuginosa 



Secondaries pale yellowish, primaries smoky brown, 



not contrasting. 

 S.t. line distinct, with preceding dusky shades or spots squara 



S.t. line partly obliterate, preceding shades on costa 



only quadrilunata 



Etacta and memhrosa are left out of consideration here. 



Hampa and jlanda are allies of staudingeri, but are larger and darker. 

 Flanda has decidedly yellow secondaries, and that is its chief superficial 

 difference from hampa. I might have deemed it racial or varietal, were it 

 not accompanied by a decided difference in the eyes; those of flanda being 

 distinctly larger, and decidedly more rounded. 



Squara is based on Greenland examples of schosnherri, from which it 

 differs by the distinctly yellowish secondaries and the totally different type 

 of transverse lines. I am, of course, assuming that all the names cited by 

 Hampson to richardsoni are really identical with the form to which he has 

 applied that name. 



The third series, in which the male autennse are ciliated only, is separated 

 by Hampson as follows: — 



Hind wings bright yellow. 



Fore wings with the ground-color deep red .... myrtilli 



Fore wings with the ground-color blackish. 



Fore wings with the reniform white-filled .... cordigera 

 Fore wings with reniform not white-filled .... mimuli 



Hind wings yellowish, tinged with brown impingejis 



Hind wings uniform brown phma 



Hind wings white, more or less suffused above with fuscous. 

 Fore wings broad, triangular. 



Reniform without whitish annuli ' melanopa 



Reniform wuth whitish annuli mimula 



Fore wings narrow, elongate. 



Fore wings pale olive-gray mausi 



Fore wings fuscous zemhlica 



Myrtilli Linn, is in our collections as acadiensis Beth., and is listed from 

 Canada northward. It occurs also in the mountains of Colorado, and I 

 have never been sure that there was only a single species represented. I 

 have compared the Colorado examples recently with German specimens.
