NOCTUIDiE. AGROTIS. 125 



fuscous : the posterior wings are whitish-yellow, with a narrow dusky margin 

 and faint central lunule ; the cilia rufescent. 

 The anterior wings are sometimes slightly blackish or dusky; and the spots 

 adjoining the stigmata vary in intensity of colour. 



Found in the vicinity of London, at Ripley, and at Darenth- 

 wood, in August. 



Sp. 22. ruris. Alts anticis pallide fuscis, vittd costali stigmatibusque ordinariis 



Jlavescenti-albidis ; posticis maris albidis. (Exp. alar. 1 unc. 4 — 8 lin.) 

 No. ruris. Hawortli. — Ag. ruris, Steph. Catal. part ii. p. 67. No. 6102. 



Also similar to Ag. nigricans, but larger, with the strigse and stigmata stronger 

 and more distinct : the anterior wings are pale fuscous, or rufescent, with the 

 costa rather paler, and the ordinary stigmata yellowish- white ; on each wing 

 are four pale yellowish-ash strigae, of which the anterior is short and basal, 

 the next transverse and undulated, the third arcuated and placed a little 

 behind the reniforra stigma, and the fourth is in the margin itself, and some- 

 times obsolete; the teUform stigma is sometimes palish, with a black margin; 

 posterior wings pale cinereous- white, with a faint central lunule ; the nervures 

 and margin dusky. 



This insect varies considerably: in some examples the strigfe are nearly ob- 

 literated ; and I possess one with the stigmata scarcely visible. As in its 

 congeners, individuals occur with a triangular dusky spot before the an- 

 terior stigma, and a quadrate one between them ; thus furnishing us with the 

 No. sordida of Haworth. 



Rare near London, but found at Darenth-wood. " Whittlesea- 

 mere, in August last.*" — Mr. Weaver. " In Norfolk." — A. H. 

 Haworth, Esq. 



Sp. 23. dubia. Alts fuscis vel nigris strigis stigmatibusque ordinariis satura- 

 tioribus, striga alia posticd conspicud, undulatd, alba. (Exp. alar. 1 unc. 6 lin.) 



No. dubia. Haworth. — Ag. dubia. Steph. Catal. part ii. p. 67. No. 6103. 



Anterior wings deep brown or black, with four darker transverse strigae, the 

 anterior stout, the second broad, geminated, and considerably waved, the 

 third greatly bent, submoniliform, and somewhat remote from the posterior 

 stigma, between which and the hinder margin is another undulated one, ac- 

 companied by a conspicuous streak of white dots ; in the margin itself is a 

 row of minute black spsts ; the stigmata are dusky with their edges darker, 

 and a quadrate deeper spot between them : the posterior wings are nearly of 

 an uniform dusky hue, with a deeper central lunate spot, and the nervures 

 slightly blackish. 



Found near London, with the foregoing species, of which it may 

 probably be a mere variety, though its appearance is widely dif- 

 ferent.
