white, more or less obvious, edged with black scales, outwardly angled 

 on the sub-costal. A blackish shade below median vein at base. T. a. 

 line geminate, defining lines black, included shade white or of the palest 

 ground ; inner defining line often obscure or wanting ; outer line some- 

 times wanting, the white included space then alone obvious : in course it 

 is inwardly oblique from the costa to the median vein, then a little out- 

 curved to the submedian, below which it forms a long outward tooth. 

 T. p. line geminate, abruptly bent from costa over the cell, then very 

 even, parallel with the outer margin : the inner defining line is black or 

 blackish, not contrasting, lunulate, broken ; outer line blackish, even, 

 broken on the veins, tending to disappear, remaining longest over the 

 costal area ; included space pale, sometimes contrasting, sometimes merg- 

 ing into the paler tinting of the s. t. space. S. t. line pale, distinct, very 

 slightly irregular, almost lunulate, in some cases relieved by the darker 

 terminal space and by preceding black spots and dashes in the s. t. space. 

 There is a series of black terminal lunules. Fringes pale, with dusky 

 interlines. Claviform black margined and more or less suffused with 

 black, extending half-way across the median space. The orbicular varies 

 from almost round to an irregular oval, is oblique, white-ringed, the 

 upper margin sometimes cut by the pale subcostal, the centre brown or 

 luteous. Reniform moderate in size, varying from almost lunate 

 to kidney-shaped, pale ringed, the upper and lower edges usually 

 broken by the white vein, centre brown or luteous. The 

 s. t. space on the whole is paler than the median space, and 

 on veins 3 and 4 and 6 and 7 pale rays extend to but rarely even 

 indent the s. t. line. The apex is pale. A dusky shade is on the costa 

 in the s. t. space. The cell is black or blackish around the ordinary 

 spots. Secondaries smoky yellow, darkening to blackish outwardly, the 

 fringes whitish. Beneath gray, ranging to smoky or to yellowish ; both 

 wings with a more or less obvious outer smoky shade line ; secondaries 

 tending to become darker beyond the dark line, and with a small discal 

 spot.

Five males and seven females in fair or good condition are before 

 me. The species is a variable one, no two specimens at all alike and yet 

 evidently all forms of one species. It resembles Ridingsiafia, Grt., and
