 whitish fringes, pale, transparent, ashen, with darker broken ter- 

 minal line. Beneath the primaries are fuscous aslien ; hind wings

Dianthoecia pensilis, n. s.

 blackish, with a certain resemblance to Mamestra diatincta. 

 Primaries whitish at base, Avith a black basal longitudinal streak. 

 Median lines geminate, pale gray, approximate below median 

 vein. Claviform deep black, acute, extending to median shade, 

 apparently resting on a very fine black line which crosses the 

 median space. A very obvious bright brown shade extends 

 above it, below the median vein, from the t. a. line downwardly 

 below vein 2 to the t. p. line. A similar but fainter shade stains 

 the discal tield be^'ond the reniform spot. Orbicular narrow, 

 whitish, oblique, with an interior streak. Reniform pale, upright, 

 moderate, with an incomplete interior black annulus. T. p. line 

 lunulate, projected straightl}' outwardly along costal region,

vein 2 on subterniinal space setting off the lower black cuneiform
