BOMBYCIDiE. 



Dasychira Groenlandica Wocke, Zweite Deutsche Nordpolarfahrt, Bd. 2, Abth. I, p. 

 409. Ent. News Vol. 3, No. 3, pi. 2, figs. 1, 2, 3. 



This species was described in 1874 and so far as we know has 

 never appeared in any of our American lists. An allied species^ 

 Dasychira Rossii, has improperly been placed in the genus Laria. 

 D. Groenlandica is of a smoky black subdiaphanous color with 

 strongly marked black neuration of the superiors. The female is a 

 heavy-bodied insect and in our one specimen devoid of marking. 

 There were two males which differ considerably but undoubtedly 

 belong to the same species. D. Rossii has a black border to the 

 wings entii'ely wanting in Groenlandica. 



NOCTUID^. 



Plusia parilis Hubner. 



There were two specimens of this rare and strongly marked 

 species. 



Anarta Eichardsoni Curtis. 



Several specimens of both sexes ; a very variable species. 

 Anarta Zetterstedi Staudinger. 



A number of specimens that present a great amount of variation, 

 some being a rich velvety black with the white lines strongly 

 brought out and others ftiintly marked. These presented as great 

 difficulties as the specimens of Argymiis, no two being exactly alike 

 and we have no doubt some entomologists would make a number of 

 species out of them, but there are no missing links in the gradations. 



Anarta Besla n. sp. 



Expands 21 mm. Upperside: Superiors gray with a yellow 

 luster, immaculate ; fringes gray. Inferiors same as superiors 

 except that the fringes are white. Underside similar to the upper 

 except that there are indications of a white band crossing the center 

 of both wings from the costa of the superiors to the lower margin of 

 superiors and there is a faint lunate spot in the middle of the infe- 

 rior and one above the center of the superior. Thorax, abdomen, 

 head, etc., above and below, of a dark gray, almost black. This 

 comes near A. Zetterstedi and may be an extreme form of it.
