fnorwegica Stgr. 



1861, Stgr., Stett. Ent. Zeit., XXII, 383, Agrotis. 



1901, Stgr. & Rebel, Cat. Lep. Pal., I, 150, No. 1374, Agrotis. 



1903, Hamp., Cat. Lep. Phal. B. M., IV, 272, opipara, Euxoa (Euxoa). 



1914, Warren, in Seitz, Macrolepid., Ill, 32, ?=^opipara, Euxoa. 



A photograph of the type of dissona (Staiidinger Collection) shows 

 the name to represent that form of the species with a slight black 

 shade between the spots and with a slight median shade line ; but the 

 claviform is not extended by dark shading to the t. p. line, nor are 

 the dark shadings much intensified. Holland's figure (1903) is not 

 quite typical. 



The name vara is unavailable in any capacity, being a misidenti- 

 fication of, and a lapsus calami for, rava U.S. 



The type of opipara is in the British Museum, and according to 

 Hampson (1903) has the claviform connected to the t. p. line by a 

 black shade. Hampson's figure apparently represents either the type 

 or a typical specimen. The name may be saved for the form with 

 the blackish shade markings generally intensified, and the claviform 

 connected to the t. p. line by a black shade. The figure in Seitz (1914) 

 is apparently a copy from Hampson, but is rather poor and conveys 

 an erroneous impression, 



A photograph of the type of lahradoriensis (Staudinger Collec- 

 tion) shows the same markings as the type of opipara. The name was 

 sunk as a synonym by Staudinger and Rebel (1901), Hampson (1903), 

 Warren (1914), and Bang-Haas (1922). 



The name islandica Auct. nee Stgr. is the result of various mis- 

 identifications of islandica Stgr. by authors. Staudinger & Rebel list 

 the figure of islandica Auriv. nee Stgr. (Bihang Vet. — Akad. Handl., 

 XV, 15, pi. I, f. 5) as being opipara, and in this are followed by Hamp- 

 son. Either the figure is poor or probably refers to some other species. 

 Hampson also lists islandica Pack, nee Stgr. (1874, Ann. Rept. U. S. 

 Geol. Surv., (1873), 555, pi. — . f. 10), but evidently did not study 

 the figure as his reference is erroneous being "1878. Bull. U. S. Geol. 

 Surv., IV, 555". This figure appears to be a Chorisagrotis. Packard 

 states "three larvae which I refer doubtfully to this species . . ." 

 (islandica Pack, nee Stgr. = ?Chorisagrotis sp.) ; are credited by 

 Hampson to Packard as a description of the larvae of opipara, and
