of very acute points, with dots between, and no other markings ex-

Agrotis Okakensis n. sp. 



? . Cinereous, with an obscure lilac tinge. Head and palpi sable- 

 brown, as is also the prothorax. Antennte pale, whitish above, 

 minutely ciliated. Thorax concolorous with the fore wings, while the 

 abdomen is concolorous with the hind wings. Fore wings pale ashen, 

 with a slight lilac tinge, especially on the costal and outer and inner 

 edges, the middle of the wing being reddish-brown, which tint runs 

 into the costa near the apex, where are also three minute oblique 

 parallel whitish streaks. An oblique brown line, partially obsolete at 

 the base, goes from the costa inwards. The inner discal dot is a large 

 triangular, very conspicuous pale spot, dai'ker within, and becoming 

 obsolete on the costa, as if truncate. An oblique whitish stripe on the 

 submedian, just below the inner triangular spot. The reniform dot is 

 close to the inner discal dot, the lower lobe is much the larger, and 

 the edge whitish, within lilac-cinereous ; between the two spots the 

 wing is clear brown. An outer obscure brown line forms a great 

 S, curving inwards regularly from near the inner angle, then sweep- 

 ing by a great curve outwards, opposite the discal spot, being once 

 acutely, finely toothed just below the costa, and thence going obliquely 

 by a straight course back on to the outer fourth of the costa. A little 

 beyond is a similar, more obscui-e submarginal line, beyond which the 

 margin is lilac-gray ; a marginal row of brown linear spots , fringe 

 ashen-brown. Hind wings with no line, discal spot obscure and dif- 

 fuse. 



Beneath, the same as the hind wings above, with no cross-lines, while 

 the discal dot on both wings is diffuse, but distinct. Costa a little 

 more dusky, edge of fore wings slightly pale cinereous, concolorous 

 with the costa of the hind wings. Legs brownish. 



Length of the body .65 ; fore wing .60 inch. 



This species is smaller than Agrotis Wockei Moschler, differing in 

 havino- no common line on the under side ; in having no dark streaks 

 wanting the subapical dark spots. The reniform dot in A. Okakensis 

 is larger beneath, while the inner discal dot is much larger and dis- 

 tinctly triangular. Otherwise it is more closely related to A. Wockei 

 than any other species.
