Agrotis gravis Grote. 



i 9. — California, Mr. Hy. Elwards, No. 3488. A fresh specimen has the 

 costal region stained with purple above on fore wings. A female specimen is 

 numbered 5G60, agreeing with the male in color. 



Agrotis rapnlaris n. s. 



S . — Allied to gravis but the fore wings narrower, blackish, with the subter- 

 minal dashes very jdistinct. Orbicular very small, pale ringed. Thorax blackish, 

 like fore wings. Beneath fuscous with common line and distinct discal spots. 

 Hind wings a,bove blackish fuscous. Two specimens, Mendocino, Mr. Behrens; 

 No. 3748, California, Mr. Hy. Edwards. This species is darker than intrita and 

 with more distinct ornamention. I have been formerly of opinion that my single 

 specimen was a form of grams. 



Expanse, 28-32 m. m. 



Agrotis aeneipennis n. s. 



i ¥ . — Allied to gravis, but the color is bright brown, shining, and the orna- 

 mentation is obliterate. This species has been sent to me by Mr. James Beh- 

 rens (No. lOOS-1010, males). I have it also under the number 2622 (female) 

 from Mr. Hy. Edwards, who also sends in the present collection two males (Nos. 

 5636 and 1390) in which the stigmata are outlined and the lines faintly visible. 

 It is readily distinguished from gravis by its color, but as the ornamentation is 

 variably distinct, I am afraid to insist on any characters drawn from ornamen- 

 tation. By breeding it may eventuate that it is a race or variety of gravis, 

 which it slightly exceeds in expanse. 



Agrotis Ridingsiana Orote. 

 Sierra Nevada, Cal. Mr. Hy. Edwards, No. 3506. 



Agrotis strigilis n. s. 



9 . — All the tibiae spinose; belonging to the tessellata group. Fore wings 

 thorax and head, blackish fuscous, somewhat olivaceous; at base of head and 

 collar some ochery scales. The transverse lines are obsoletely geminate; the 

 white or gray included shades are prominent and relieve the accompanying dark 

 transverse lines. Lines dentate, nearly perpendicular. Stigmata moderately 

 large, shaded with whitish ; claviform concolorous, barely indicated. Termi- 

 nal space a little paler; s. t. line fine, powdery gray; fringes concolorous. Hind 

 wings pale fuscous, with paler interlined fringes; beneath translucent centrally 

 with powdered costal region, faint discal mark and line. 



Expanse, 32 m. m. Vancouver Island, Xo. 5G52, Mr. Hy. Ed- 

 wards.
