shade ; t. p. line indistinct, narrow, indented opposite the cell, sli-glitly 

 luuulate, followed by a pale shade; the median space paler than the 

 rest of the wing. Orbicular rounded, moderate, with faint black an- 

 nulus, stained with reddish, and pale ; reniform near t. p. line, moder- 

 ate, "U'ith dar4s: and reddish stained center and pale border. Median 

 shade dark and diffuse ; clavi form obsolete. Fringes concolorousj s. t. 

 line fine and pale. Hind wings dark fuscous, with pale fringes. Be- 

 neath pale, with reddish tinge, irrorate ; a faint common mesial line 

 near the discal dots, which are small, and appear to be empty ; on pri- 

 maries a subterminal shade." 



Expands 34-36"""; 1.36-1.45 inches. 



Habitat. — California, Vancouv^er. 



An easily recognized species of which I have seen females only. It 

 is unlike any other species in the genus, and is distinguished by the 

 pale median and heavily powdered basal and terminal spaces. 



Adelphagrotis yernilis Grt. 



1879. Grt., CaD. Ent., xi, 57, Af/rotis. 



1879. Grt., N. Am. Eut., i, 38, Jgrotis. 



Head, thorax, and primaries dark ash gray, veins marked with black- 

 ish; transverse lines obsolete; a black basal dash, modified into the elon- 

 gate claviform ; orbicular slightly paler gray ; elongate oval, outlined in 

 black ; reniform moderate in size, kidney-shaped ; secondaries blackish ; 

 beneath, the usual lines and spots are nearly obsolete. 



Expands 37""" ; 1.5 inches. 



Habitat. — Colorado, Nevada. 



Easily distinguished by the simplicity of its maculation ; a single 9 

 is in Mr. Neumoegen's collection and I have not seen a $ . 



Mr. Grote's original description is diffuse and comparative with albalis 

 and other species which differ structually from the present; it is there- 

 fore not reproduced here, the above being sufficient to distinguish it 

 from all its associates. 



Adelphagrotis iuflmatis Grt. 



1880, Grt., N. Am. Eiit., i, 93, Afjroiis. 



Pale ash gray, costal space for half the distance to apex whitish, that 

 color invading the elongate, narrow, open orbicular; a diffuse black 

 basal dash, above sharply limited by the costal white space, medially 

 extended to outline the narrow pale claviform, and curving superiorly 

 to form the lower boundary of the orbicular ; reuiforni narrow, darker, 

 lunate; t. p. line indicated by a double series of venular dots, a diffuse, 

 darker gray, longitudinal median shade, and a triangular darker patch 

 at internal angle, the base of which rests on outer margin ; abdomen 

 and secondaries whitish ; beneath as usual, save that the extra discal 

 line is unusually crenulate.
