Morrison.] 136 [November 4, 



perpendicular, its inner component line diffused, clearly defining the 

 basal space, its' outer line narrow, dark brown, and continuous, form- 

 ing a dent beneath, the submedian nervure. The median space is 

 shaded with brown, particularly in the neighborhood of the spots. 

 The ordinary spots are all very large, annulated with black and filled 

 with cinereous, which is overspread with dull gray. The reniform 

 spot has traces of an internal annulus, and is of the normal shape. 

 Orbicular spot very long, extending below the median nervure. 

 In one female the reniform spot is normally formed above, and 

 outwardly, but inwardly it is joined to the orbicular. Outer por- 

 tion of the claviform spot alone apparent; in the abnormal speci- 

 men before mentioned it joins above the annulus of the orbicular 

 spot. Median shade rounded, dark brown and diffuse; it appears 

 above and below the united spots. The exterior line is of the usual 

 form, its inner component line fine and denticulate, the outer, broad 

 and continuous, defining the dark subterminal space. The sub- 

 terminal line is faint and irregular, preceded by a series of very 

 conspicuous, black, cuneiform markings, those opposite the cell the 

 largest. A series of triangular dots at the base of the fringe. Pos- 

 terior wings dark grayish fuscous, with a discal dot, and an indistinct 

 line. A black interrupted line at the base of the white contrasting 

 fringe. Beneath more or less distinct gray; the discal dots, median 

 line, and a terminal black shade band common to both wings are 

 present. The costa of both wings tinged with dull carneous. 

 Hab. New Hampshire, in August. 



I am indebted to Mr. Holmes Hinckley for one of his two speci- 

 mens of this fine species, as well as for other interesting material. 

 It resembles Mamestra purpurissata Grote, but is much larger, and 

 also differs in its strong generic characters. 

 Polia perquiritata nov. sp.

 with fine hairy clothing, and with a tuft at the base. Collar hollowed 

 o it. Thorax having a low fore and hind tuft; mixed black and white, 

 the hind tuft entirely black. The collar and tegulae are edged with

 black, white, and gray; all the markings very prominent and con- 

 trasting. A short, black, basal, longitudinal, submedian branch. Basal 

 space black. Half and interior lines double, each enclosing broad 

 white bands, the latter strongly outwardly lobed, particularly between
