AGROTIS FOPtMALIS, Grote 



$ . — An exceedingly dark and beautiful species, with silky squamation 

 and somewhat flattened form and allied to our ea.stern .-/. follfiris and 

 A. (/eiiiculnta. Middle and hind tibiae spinose. Dark intense blaskish 

 brown. The collar has a narrow central pure white line, above which the 

 lihothoracic pieces are velvety black. Piimaries with the costal edge 

 broadly dark ashen to the inception of the t.p. line, absorbing the superior 

 portion of the orbicular spot. Reniform gray, like the costal edge, mod- 

 erate, with faint dark internal ring. Ordinary lines geminate, fine not 

 very distinct or complete, black. The t.a. line waved, nearly perpendicular. 

 The basal half-line visible on the gray costal edge. The t.p. line roundly 

 but not greatly exserted opposite the cell, follow^ed by minute black and 

 white points on the subterminal space. Median space with a more ruddy 

 lirown tinge than the rest of the wing and like the thorax and tegulae. 

 The faintly pale subterminal line is shaded with brown and the dark fringes 

 are brown at base and sliow a faint interior line. Hind wings blackish 

 without marks, with white-tipped fuscous fringes that show a liroad in- 

 terior line. Abdomen blackish. Beneath the wings are a little paler, 

 irrorate, with a rather distinct blackish common line and black diseal mark 

 on the hind wings. 



Expanse 3-5 """. One fresh specimen, Mr. Beliren.s, California. Coll.

This appears to be Dr. Smiths' idea of exsertistigma, in part.
