filling of the cell. Transvere posterior line unusually sharply denticulate; the 

 pale Bubterminal line preceded by large cuneiform brown marks. An inter- 

 rupted black terminal line on the margin ; fringes light brown. Hind wings 

 fuscous without markings, save from the reflection of the black and distinct 

 discal liture of the under-surface ; fringes as on primaries. Beneath fuscous 

 without markings except the discal spots, which are unusually broad on the 

 secondaries. Thorax above brown with darker lines on the collar. 



Expanse, 40 m. m. Habitat, Vancouver's Island (coll. Mr. Ily. 

 Edwards, No. 2634). 



A rather large, broad-winged species, allied to A, oLeliscoides and 

 A. yenerabilis, differing by the dentate and distinct transverse pos- 

 terior line. 



Agrotis sancia {Buhner). 



Habitat, California (coll. Mr. Ily. Edwards, No. 157). The Amer- 

 ican specimens, described by Harris as Agrotis i^ierinis, are not dis- 

 tinguished. In the same way Harris describes our specimens de- 

 termined by Guenee as Agrotis suffusa, under the name of Agrotis 

 telifera. 



Agrotis Wilsoni, Grote, Plate 4, fig. 3, $, . 



$ . — Hind and middle tibiae spinose. Eyes naked. Antennae bristled, the 

 joints with lateral fascicles. Fore wings singular in appearance, as if overlaid 

 from the base to the terminal space with a smooth olivaceous-ochrey shade, in 

 which the distinct, black, pale-circled, attenuate ordinary spots appear as if 

 cut out. At the base of the wing are some blackish marks indicating the basal 

 half-line. On costa there is a darker somewhat ferruginous shade preceding 

 the inception of the subterminal line, which is inwardly dentate opposite the 

 cell and may appear by contrast against the blackish terminal space. No or 

 very faint traces of the ordinary lines. Terminal line a series of very distinct 

 black linear marks. Secondaries fuscous, a little paler basally, with whitish 

 faintly interlined fringes. Beneath very pale, without lines, but with the 

 reniform on the primaries distinctly reproduced and a black discal comma 

 mark on the hind wings. Thorax with ferruginous shades on the collar and 

 centrally ; abdomen pale ochreous with the anal hairs reddish. 



Expanse, 37 m. m. Habitat, California (Mr. James Behrens, 

 No. 12). I know of no species resembling this in ornamentation. 

 I respectfully dedicate the species to Mr. "Walter T. Wilson, whose 

 services to Natural Science deserve to be held in remembrance.
