This is the Agrotis subgothica of American Agricultural Publica- 
toins, such as the 1st Missouri Report, page 82, fig. 29. It is not the 
Agrotis subgothica of English writers, which is A. jaculifera Gwenée. 
Stephen’s figure of Agrotis subgothica, Plate 22, fig. 3, and descrip- 
tion, page 126, Haust. II, is decisive. The peculiar discoloration of 
the reniform spot distinguishes A. jaculifera, and the paler hind 
wings, greater extent of pallid shades on the fore wings and smaller 
size are characteristic and are all well rendered by Stephen’s illus- 
tration. When I was in France, M. Guenée stated to me that 
he had discovered the fact, that his Agrotis jaculifera was the same 
as the Agrotis subgothica of English writers, and also that he 
believed that the form now deseribed as Agrotis herilis was a dis- 
tinct species; the latter contrary to the statement made in the 
Spécies Général. Agrotis subgothica is figured on Plate 1, fig. 11, 
in the 1st Missouri Report correctly, but under its synonym of 
Agrotis jaculifera, which latter name I retained for the species in 
determining the Noctuidae of the collection of the American 
Entomological Society, whence Mr. Riley received his determination. 
I was not then able to examine the English authors, who first 
noticed our species from specimens accidentally introduced into their 
country. Mr. Riley’s figures of A. herilis, above cited, have been 
copied, with the erroneous determination, by Eastern writers. 
Agrotis sexatilis, Grote. 
6 @.—Ocelli; eyes naked; all the tibiae spinose ; middle tibiae with one, 
hind tibiae with two pair of spurs; ¢ antennae bristled, ¢ simple, oviduct 
slightly produced. Ornamentation typical, in color like A. plecta, than 
which this is a larger species. Costal edge broadly whitish in ¢, ashen in 
?, ordinary spots very large, separated, preceded and followed by black 
scales, variable in tint. Median lines black, tolerably distinct. Internal 
margin, from the base of the wing to transverse posterior line, broadly and 
diffusely shaded with blackish. Subterminal space broadly shaded with dull 
purple reddish, smooth; this tint spreads inwardly below vein 2 over the 
median space to the prominent black-edged claviform spot. Subterminal 
line improminent. A narrow terminal black line interspaceally accentuated. 
Hind wings dark fuscous, without border or spot in 9; whitish with smoky 
posterior shading in ¢. Beneath dusky, with very faint traces of a common
