Dr. Morris' reference, to which Prof. Eiley objects, has its origin in 

 the fact that both Harris and Guenee identify Abbot's aceris under 

 different names. Acericola (aceris imcKjo), is unidentified by actual 

 specimens. 



Agrotis gravis Grotc. 



3 S . — All the tibiae spinose. Nearest to A. volubilis and the European A. 



tera, a little smaller than either of these. Male antennae bristled, with 

 the joints laterally acuminate. Fore wings dull gray brown with darker costal 

 region ; the female is more purely brown. A dark basal dash extended beyond 

 the t. a. line as the dark margined prominent acuminate claviform, less elon - 

 gated than in volubilis, and very much less prominent than in valligera. Orbi- 

 cular small, dark, light ringed, in the male with an edging of whitish scales 

 which also partially edge the dark upright moderate reniform. T. p. line faint 

 and narrow, regularly scalloped interspaceally. Subterminally, in the male, 

 opposite the cell are a series of interspaceal cuneiform marks followed by 

 whitish points, somewhat as in wdligera; these are not noticeable in the female, 

 in which the s. t. line is indicated by a dark shade followed by the paler tinting 

 of the subterminal space. Hind wings dark fuscous, a very little paler in the 

 male and reflecting from the under surface the discal lunule. Beneath fuscous, 

 with indistinct transverse line. Tegulae more or less hoary and contrasting; 

 collar with a distinct black median line, margined above with whitish, more 

 distinctly in the male. The contrast in general tone of the sexes is obvious, the 

 male being more blackish gray, with a faint olivaceous tinting, the female brown. 

 In A. volubilis the 2 is the darker and here the reverse seems to be the case. 

 The median shade is well marked in one female specimen and the color of the 

 cell between the spots is here obviously deepened. The fringes on the ? hind 

 wings are testaceous with an interior line. In the single male specimen I have 

 they are defective. Four ? one S specimen from Mendocino, and numbered 

 83/84 and 131/132 by Mr. Behrens.

A single male specimen differs by the almost wholly blackish pri- 

 maries, the brown black, not hoary thorax, else the markings arc 

 those of the species and are well brought out, on the primaries. 



Note. — By a typographical error the reference to Agrotis fennica, 

 on page 10 of my list, has been dropped to the following line. The 

 two species should be cited as follows :
