to the outer margin through the submedian interspace, the line set in 

 a blackish shading, which extends on each side and is dilfuse at the 

 edges. Basal line blackish, geminate, toothed on the veins. Trans- 

 verse anterior line geminate, black, the two parts equally distinct, 

 widely separated on costa, gradually becoming approximate toward 

 inner margin. In course it is irregular, the long inner tooth on sub- 

 median vein being best marked. Transverse posterior line unusually 

 near outer margin, leaving a very wide median space, geminate, outer 

 line best defined, narrow, black, inner smoky, included space white, 

 irregularly angulate and dentate, squarely exserted over the reniform, 

 drawn in below, a prominent outward tooth in the submedian inter- 

 space. Subterminal line whitish, irregular, incomplete. A series of 

 black terminal spots, forming the tips of sagittate blackish marks 

 which cut the fringes. A blackish irregular bar fills the subterminal 

 space opposite the cell. Median shade black on the costa, oblique 

 through the reniform, becoming smoky, then irregular and close to the 

 transverse posterior line. No obvious claviform. Orbicular round or 

 oval, then annulate with whitish, center concolorbus. Reniform large, 

 broad, irregularly kidney-shaped, larger superiorly, ringed with black, 

 filled with smoky or blackish. Secondaries almost white, with a 

 smoky, punctiform, exterior line and a series of smoky terminal lunules. 

 Beneath white, powdery, both wings with a more or less complete, 

 sinuate, outer line and good-sized discal spot. 



Expanse, 37 to 41 mm. =1.48 to 1.(54 inches. 



Habitat. — Texas. 



Two males and one female, the latter greasy and a little defective. 

 The species is altogetlier different from the other described species, 

 and the black- shaded streak through the submedian interspace of 

 primaries will distinguish it at a glance. 



Type.— Cat. ^o. 4812, U.S.N.M. 



57. MAMESTRA SENATORIA, new species. 



Grround color very deep purplish brown, overlaid and powdered with 

 black scales, orbicular, reniform and terminal space more or Jess yel- 

 lowish, contrasting. Head and thorax without obvious maculation. 

 Primaries with the lines lost in the black powdering, marked on the 

 costa by geminate black spots inclosing a yellowish mark, and by yel- 

 lowish scales which represent the space included between the geminate 

 lines. Basal line thus marked for its full course. Transverse anterior 

 line apparently upright or nearly so. Transverse posterior line lunu- 

 late, apparently of the usual form, fairly evident over the cell. A 

 vague, curved, diffuse, median shade. Subterminal line dull yellow, 

 distinct, continuous, a little irregular, preceded by black blotches in 

 the interspaces ; that opposite hind angle being largest and most 

 obvious. Terminal space mottled with yellow scales. Fringes long, 

 feebly scalloped, cut and festooned with dull yellow and with a blackish
