 the contrasted white and red of its orbicular and reniform spots. 



Acronycta lithospila Grote. 



? . In the shape of the wings and streaky shadings of the prima- 

 ries this species is allied to A. Xylinoides Guenee. The ornamenta- 

 tion is almost entirely obliterate, the transverse lines marked by even 

 oblique darker shades on costa. The color is dark steel gray with 

 dull, inconspicuous, brownish shading on the cell, behind and accom- 

 panying the transverse posterior line and about the long, black, basal 

 streak. The t. p. line is dentate, more evident than the other lines ; 

 it is even on the costal region and is seen to run further back than in 

 A. Xylinoides. Whitish streaky shadings may be noticed on the cell 

 accompanying a black discal streak, above internal angle below a very 

 fine black streak, and again on submedian interspace before the t. p. 

 line and on a line with the black basal streak. The reniform is in- 

 completely indicated. Terminally the fore wings are paler grey with 

 the veins marked with dark grey and with dark interspaceal shade 

 streaks on the margin, accentuating the terminal dots so that the ter- 

 minal space has a succession of blackish stripes on a paler grey 

 ground. Hind wings whitish, with smoky nervules and faint, unde- 

 fined terminal shade band. Beneath whitish, dusted with smoky 

 scales, and with improminent discal mark and line on the hind wings. 

 Thorax and head concolorous with fore wings. Palpi whitish, with 

 the second joint black at the sides. 



Expanse 35 mm.

In the markings this species resembles closely a gray Leucania, or 

 Xylina.
