and am by no means certain that the two are identical. The resemblance 

 is very close, however, and my material is not sufficient to induce me to 

 dispute the union. 



Cordigera Thumb, is a very sharply-marked species, and I have in my 

 collection examples from Colorado, Labrador and Germany, which are 

 practically alike. 



Mimuli Behr. is a Californian species unknown to Hampson, and not 

 represented in my collection. The type has been destroyed in the San 

 Francisco fire. 



Impingens Wlk. — with curta Morr., nivaria Grt. and perpura Morr. 

 as synonyms — is a purely American species, which differs quite markedly 

 from the preceding species in general habitus, and comes nearer to Scoto- 

 gramma in wing-form. I have it from Colorado onl}^; but it is also recorded 

 from British Columbia. 



Phcea Hampson is a new species to our fauna, and quite a close ally, in 

 appearance, to the preceding. It comes from Victoria Land, Cambridge 

 Bay, and is not represented in my collection. 



Melanopa Thunb., re-described by Packard as nigrolunata, is another 

 sharply-defined form which is very widely distributed. It occurs in the 

 United States from -Mount Washington northward, and extends along the 

 Rocky Mountain chains into New Mexico. My examples are from Col- 

 orado and Labrador, without very much difference between them. 



Miviula Grt. is from New Mexico, and the type is in the Snow Collection. 

 Professor Snow was good enough to send it to me for examination nearly 

 fifteen years ago, and since that time I have not seen another example, so 

 far as I know. 



Laerta Smith was not known to Hampson when he wrote, and differs 

 from melanopa in the more sordid fuscous color throughout and by the much 

 reduced whitish area of secondaries. From mimula it differs in the ordinary 

 spots, the rcniform not being ringed with pale scales. This really resembles 

 A. kelloggi Hy. Edw. very much; but Hampson places that species in 

 Sympistes with naked, reniform eyes, while in laerta they are distinctly hairy. 



Mausi Hampson is from E. Turkestan, and the only species in the series 

 that is not American or circum-polar. 



Zemblica Hampson is from Nova Zembla, and is a narrow-winged ally 

 of mausi. While not really American, it is not unlikely that the species 

 will be found in Alaska, and so should be looked for. 



The other species referred to this genus I have commented upon in the 

 N.Y. Ent. Soc. Jour., 1907, Vol. XV, p. 151, and have there stated the 

 disposition made of them. 



I still have in my collection a few examples that do not fit into any of the
