Notes on North American Lepidaptera. 97 



Mamestra promulsa, nov. sp. 



Expanse 35 mm . Length of body 15 mm . Eyes hairy. Palpi ochreous. 

 Villosity of the front, thorax and collar coarse and rough. Abdomen 

 smooth and untufted, covered with mixed gray and yellow scales ; in the 

 female with a short, thick, projecting ovipositor. 



The wings are thinly scaled, nearly unicolorous, the ground color being 

 olivaceous gray, overspread with numerous yellowish scales ; the median 

 lines are blackish, diffuse, irregular and dentate; the subterminal line 

 forming a series of blackish blotches, interrupted, and some times barely 

 perceptible ; the orbicular spot obsolete, the reniform reduced to a blackish 

 stain ; the median shade is seen at the costa and inner margin in diffuse 

 spots : a yellow line at the base of the concolorous fringe. Posterior 

 wings colored like the primaries, with a more or less distinct cliscal dot. 

 Beneath, yellowish gray, with black discal dots and a diffuse, thick, but 

 angulate median line. 



Habitat. Colorado (Mr. T. L. Mead), July 20. 



We refer this interesting species to Mamestra provision- 

 ally ; the two specimens we have were placed in papers, so 

 that the thoracic tufts are much defaced ; we think that on 

 the discovery of fresh specimens it will probably become the 

 type of a new genus. 



Scopelosoma devia, Grote. 



Expanse 36 mm . Length of body 17 mm . The thorax is concolorous 

 and provided with a sharp edged longitudinal crest behind the collar. 

 The anterior wings have their apices rectangular; half-line present, 

 whitish ; the basal space brown, closely and evenly sprinkled with white 

 atoms; the interior line white, even, oblique, and concave, contrasting 

 strongly with the deep brown of the central and outer portion of the 

 wings ; the reniform spot is reduced to a fine white concave line, the or- 

 bicular absent ; the exterior line is very tine, whitish, and broadly undu- 

 lating, subparallel with the subterminal line which is also fine and clear; 

 between these two ordinary lines there is another very distinct white 

 concave line, parallel with the interior line and most distinct at the apex ; 

 outwardly this line contrasts with the brown subterminal space, inwardly 

 it is suffused, but finally lost in the brown ground color before the exte- 

 rior line ; there is a sprinkling of whitish atoms towards the end of the 

 terminal space ; at the base of the brown fringe there is a bicolorous un- 

 dulate brown and white line, outwardly the fringe is narrowly edged with 

 white. The posterior wings are uniform dark fuscous, the fringes light. 

 Beneath, the anterior wings are gray, with an indistinct double exterior
