Mamestra gussata n. sp. PI. xv, fig. 9. General color a warm reddish 

 gray, varying somewhat in the specimens, and sometimes becoming 

 brown. The head and thorax are immaculate, but the scales are a little 

 gray tipped, giving the vestiture a hoary appearance. The ordinary lines 

 are evident, but not well marked. The basal line is denned in some 

 specimens, and is black, reaching to the submedian vein and there bent 

 inward to the base, so that we have the appearance of a short basal streak ; 

 in some specimens it is marked only at this point. The t. a. line is well 

 removed from the base, forms three evident outcurves and is, as a whole, 

 outwardly convex. It is black, preceded by a slightly paler shade, and 

 occasionally this is inwardly limited by a few dusky scales. The t. p. line 

 is pale, inwardly defined by dusky scales, which become blackish lunules 

 below the median vein in some specimens. It is sometimes almost obso- 

 lete opposite the cell, is tolerably even, widely bent over the reniform 

 and then strongly incurved below that point, so that the median space 

 becomes very narrow, inferiorly. The s. t. line is well marked and pale, 

 in some specimens preceded by a distinct dusky shade, which, however, 

 is sometimes absent; occasionally the line is defined only by a somewhat 

 dark terminal space. There is a very narrow terminal line. The clavi- 

 form is evident and extends across the median space in the form of a black 

 streak. The orbicular is large, oval, oblique, gray in color, defined In- 

 black scales; and usually the space between the t. a. line and the orbicular 

 is dusky. The reniform is also large, gray, a little constricted centrally, 

 black margined inwardly, but sometimes indefinite outwardly. Seconda- 

 ries smoky, sometimes with a reddish tint, but without distinct markings. 

 Beneath pale smoky, the secondaries with a blackish discal soot more or 

 less marked. Expands 30-38 mm.; 1.20-1.52 inches. 



Hab. Calgary, in April. 



Mr. Dod writes concerning this species that it is " not rare at 

 Sallows, end of April." Five specimens from the basis of the 

 above description, and in a general way the insect resembles lus- 

 tralis in appearance. The antennae in the male have the joints 

 marked and set at the sides with tufts of bristles. They would 

 thus be called somewhat serrated and bristle-tufted. 



Mamestra ingravis n. sp. PI. xv, fig. 10. Ground color a rather deep 

 lilac gray, with hoary powderings and tippings to the vestiture of the tho- 

 rax. The collar is marked with a more or less well defined, median black 

 band, below which an obvious reddish tinge prevails. The thorax has a 

 distinct divided anterior tuft, and a less defined posterior tuft resembling 

 somewhat the tufting in PID purissata; the abdominal tufting is also dis- 

 tinct. The primaries have all the markings obvious, and there is con- 

 siderable contrast between the different parts of the wing. In a general 

 way the basal space is paler, with an obvious lilac tinge; the median space 

 is darker, tending to blackish. The s. t. space decidedly contrasting and 

 has a more or less marked lilac suffusion. The terminal space is darker
