species and imbrifera, but distinct from each by the dark ashen 

 gray of the primaries as against the pale shade in nimbosa and 

 the luteous shading in imbrifera. The markings are more nearly 

 like nimbosa, but better defined. In the structure of the male 

 genitalia the species is nearer to imbrifera, but differs by the 

 absence of the spoon-shaped clasper as well as in other minor 

 details. 



Mamestra plicata n. sp. 



Ground color a dull, very powdery reddish gray or brown, almost fawn 

 color, more or less suffused by black or smoky. Head immaculate, 

 collar with two brown transverse lines and tipped with gray scales. 

 Patagiae brown at the base of the wings and with a vague, darker sub- 

 margin. Primaries with the maculation more or less obscured by the 

 dark suffusion through the lower half of the wing, the costal region 

 appearing paler by the contrast. There is a short black dash at hase, 

 above which the space is'paler and from which a pale line is indicated to 

 the inner margin. The basal half line is not obvious in my specimens. 

 T. a. line geminate, narrow, with a broad, almost even outcurve, the 

 defining lines slender and brown, the included space paler and a little 

 wider, thus relieving the line. T. p. line slender, geminate, very evenly 

 bisinuate and as a whole nearly parallel with the outer margin. The 

 defining lines are narrow, even, smoky ; the included space paler than the 

 ground color. S. t. line yellowish, distinct, forming the most obvious 

 ornamental feature and margined with a few black scales. It arises from 

 a paler apical patch and is only a little uneven in its course to the hind 

 margin. A series of small black terminal dots on a waved terminal dark 

 line. Fringes a little scalloped, with a pale line at base and cut with pale 

 beyond the veins. The claviform is long, outlined with brown scales and 

 extends nearly across the median space. Orbicular large, gray, irregu- 

 larly oval, oblique, without obvious defining line ; but with a few black 

 scales which emphasize the contrast of the gray spot. Reniform large, 

 upright, a little constricted in the centre, a little paler than ground color, 

 the lower portion filled with a dusky shade. It is outlined by black scales, 

 within which is a pale annulus. Secondaries deep, even fuscous or 

 smoky, the veins, a discal lunule and a terminal line yet darker brown. 

 Beneath reddish gray, with coarse powderings and a large blackish discal 

 spot on all wings. 



Expanse 1.40-1.60 inches = 35-40 mm. 



Hab. — Glenwood Springs, Colorado, in May; Dr. Wm. Barnes. 



One male, the smaller, and one female specimen are under 

 examination. The description was mostly from the male, 

 because in the female the blackish suffusion through the lower 

 part of the wing obscured almost everything except the s. t. line.
