 costa before exterior line. A white discal spotj interior line marked on 

 costa. Exterior line tolerably distinct, lunulate, marked on costa, as i&

 minally shaded with brown; the wings are irrorate with brown and

 metres. Several specimens, Buffalo, N. Y., in July.

 The reniform is reddish-ochreous, not white. Inner line faint, oblique,, 

 'rounded. The angles of the primaries are less pronounced and the 

 palpi less prominent. The insect is very inconspicuous, faded dusty- 

 gray, with obliterate ornamentation. Expansion, 14 millimetres. Texas

Mamestra congermana. 



Hadena congermana, Morrison, Can. Ent. vi. 106. 



I have before me Mr. Morrison's type, and the eyes are distinctly 

 hairy. I cannot see why Mr. Morrison referred the moth to Hadena. 

 He says of it [l. c.) : — "It is another member of the same little closely 

 related group of Hadena, of which duMtans Walk., and sputator Grote, 

 are the only species." This is totally inaccurate, the species being 

 nearest to Mamestra vindemialis. Its resemblance to dubitans and 

 sputator is not greater than that of vindemialis Grote, which latter may 

 be the vindemialis of Guen^e, and the rubefacta of Mr. Morrison.
