20 Grote and Robinson's Lrpidopterological 



brownish, concolorous with the basal spaces. Subterminal line greyish- 

 sligbtly irregular, continued. Teiuninal space narrow, rather darker 

 than subterminal space. Fringes dark, concolorous. 



Posterior wings very pale yellow, covered with blackish scales at ex- 

 treme base and along internal margin. A free, broad, black, subluni- 

 forni discal spot. A broad, black terminal band, sinuate along its inner 

 margin. Fringes pale, long and whitish along internal margin, partially 

 obscuring the black scales. 



Under surface pale testaceous-whitish. A blackish longitudinal 

 basal streak; two distinct, black discal spots; a subterminal sinuate 

 blackish band furcate on costa; apex tinged with reddish scales. This 

 description applies equally to both anterior and posterior wings. 



Head, thorax and their appendages, clothed with mixed brownish 

 scales; abdomen, paler, closely scaled ; under-thoracic and abdominal 

 surfaces, pale testaceous. 



Exp. % 0.80 inch. Length of body 0.40 inch. 



Habitat. — llhode Island. 



This species resembles A. marginata Grote, A. arcigera Guenee, and 

 A. Spraguei Grote, in the distinctness of the median lines on anterior 

 wings; their conformation, the grey median space and the very pale 

 yellow of the secondaries, distinguish this more hirsute species from its 

 conveners. 



AEDIA, Hubner. 

 Aedia nigrescens, n. s. (Plate 3, fig. 4, £ •) 



Anterior win2;s dark cinereous shaded with blackish. Basal and 

 sub-basal spaces evenly dark cinereous; basal half-liue black, succeeded 

 by a faint coincident linear mark. Transverse anterior line oblique, 

 slightly irregular, preceded by a faint coincident line. Beyond the t. 

 a. line, is a broad, oblique, dull, brown band, margined outwardly by an 

 oblique, dark, median, shaded linear baud, widening to internal margin 

 where it is limited outwardly by the t. p. line. This latter is shaped 

 as usual in the genus, surrounding outwardly the extra discal spot, 

 which is large, pale, with a prominent tooth outwardly directed. The 

 t. p. line is broken superiorly where it is strongest marked, being more 

 faintly indicated before internal margin. Subterminal space dark 

 blackish, deepening in hue towards the subterminal line, which latter 

 is even, a little waved, with a single inward prominent inflection oppo- 

 site the discal cell, from whence a darker shade line runs to internal 

 margin at the angle. Terminal space clear pale cinereous; a black 

 apical mark; a terminal, dark, neatly dentate line, continued from apex 

 to internal angle.
