REVISION OF SPECIES OF TIIK GENUS AGROTIS. 207 



reniform vaguo; upright, broad; the spots are picked out by a brown 

 shading which fills the cell and marks the subcostal and median veins. 

 y. t. line a vague blackish even shade. Hind wings concolorous fus- 

 cous griseous, with the veins soiled and a faint discal mark. Beneath 

 griseous, the primaries a little brownish. The costal preapical dots 

 visible beneath and to be made out on the uin)er surface. Abdomen 

 like hind wings. Head brownish; teguhe blackish; disc of thorax

!N^othing to which this description will lit is known to me. 



Agrotis viralis Git. 

 1880. Grt., IJiill. fJool. Surv., vi, 2(50, Agrotis. 

 " $ . Antennie ciliate beneath. Fore tibi;e unarmed, unless acci- 

 dentally the spines are broken off, which sometimes occurs. Pale 

 faded yellow fuscous, collar with a faint line. The lines obsolete. A 

 blackish dash at base ; another below it on internal margin ; a dash 

 across the submedian space, and the cell before and between the stig- 

 mata darker shaded. Stigmata i)ale, concolorous nioderate. Orbicular 

 outwardly oblicpie near the reniform at base; both stigmata incom- 

 pletely dark ringed. S. t. line indicated; s. t. space paler; terminal 

 space darker. Hind wings paler, nearly concolorous with fore wings; 

 darker shaded along outer border. Body concolorous; beneath with- 

 out markings; hind wings quite pale. Expanse 38""". Habitat — 

 Nebraska." 

 No species to which this description could apply is known to me. 



Agrotis juncta Grt. 

 1878. Grt., ]5ull. Geol. Surv., iv, 171, Agrotis. 



" $ . Size of Trcatii, which this species resembles in its dead black 

 primaries. Collar black at base, pale tipped. Head pale; thorax brown; 

 abdomen pale fuscous. Fore wings with the t. a. line rounded, black; 

 attached to it is the black pale-margined claviform. Ordinary spots 

 concolorous, large, finely outlined with i)ale and fused below; the 

 claviform apparently touching the orbicular at base. S. t. line fol- 

 lowed by small, pale marks. Hind wings pale fuscous. Beneath pale, 

 with indistinct common line, and discal marks obsolete. Nova Scotia 

 {Mr. Roland Thaxter). One specimen." 



Would seem to be a very distinctly marked form allied to hollemani, 

 but possibly not belonging to that group. Mr. Grote gives ns no 

 structural characters whatever to serve as an index to its position. 

 On the list he places it before haruspica and close to mnotabilis, two- 

 structurally different species. 



Agrotis fishii Grt. 

 1878. Grt., Bull. Geol. Surv., iv, 17."), Agrotis. 



" 5 . 9 . — In color and appearance resembling janualis, but the tibife
