round, small, annulate with whitish and with a dusky central dot. Reni- 

 form moderate in size, upright, a little constricted centrally, defined by 

 black scales, within which is a whitish annulus which is incomplete above 

 and below. Secondaries in the male white, with a dusky line at base of 

 fringes and the veins a little soiled ; in the female dull smoky gray, 

 darker, almost blackish outwardly — the fringes white. Beneath, male, 

 primaries with disk smoky, terminal space whitish ; secondaries white 

 with costal margin powdery ; female, primaries blackish with a geminate 

 exterior line in which the included space is gray ; secondaries whitish, 

 powdery, with an extra median smoky line and a smoky line at the base 

 of the fringes.

One male and two females are at hand : the male largest, pale 

 ash gray, with white secondaries ; the females smaller, deep 

 smoky gray, with dull, smoky brown secondaries. The con- 

 trasts are unusually strong for this genus and the large size of 

 the male compared with the female is also a little unexpected. 



The species belongs to the group laudabilis ; but the primaries 

 are somewhat broader and a little more pointed than in the other 

 species. The male antannae are simple, and the genitalia are 

 almost exactly like those of incurva. In fact the differences are 

 so small that I would consider them within the range of individ- 

 ual variation if I could in any wise bring the species into accord 

 superficially. The new species is, however, much larger, differs 

 in wing form, has the secondaries of the female smoky instead 

 of white and the primaries powdery instead of with smooth and 

 even clothing. It adds another to those small forms which in a 

 general way resemble olivacea. 



Mamestra rautilata n. sp. 



Ground color a pretty bluish gray, the primaries with yellow shades 

 and powderings. Head inferiorly, palpi and breast, dark umber brown. 

 Collar black tipped and with a smoky band above the middle. Thorax 

 a little powdery. Patagiae with a short black line at the base of the pri- 

 maries. Primaries with all the markings well defined, but not contrasting. 

 Basal line black, geminate, reaching into the submedian interspace, to an 

 ochre yellow shading. The costa is smoky to the t. a. line, else the basal 

 space is clear, bluish gray. T. a. line geminate, the inner portion dusky 

 and barely traceable, the outer black on the costa, forming a little out- 

 ward angle on the sub-costal : below it is more smoky, a little incurved 

 in the cell, then a little outcurved to the submedian and again below it. 

 T. p. line geminate, strongly outcurved beyond the cell, then inwardly
