a strigate appearance which is aided by the black margined 

 claviform ; a feature not evident to the same extent in either of 

 the other species. 



The antennae in all of the species are shortly pectinated and no 

 obvious differences appear from such examination as was made ; 

 but the structure of the male genitalia, which will be figured in 

 another paper, bears out the conclusions reached from the super- 

 ficial characters. 



Mamestra mystica n. sp. 



Ground color dark powdery ash gray with a bluish tint. Head with 

 alternating dusky and paler transverse lines. Collar with a central black 

 line, above which the tint is much darker than below it. The discal tho- 

 racic cresting is dusky at tip and so are the tips of the abdominal tufts. 

 Patagiae black marked at the base of the primaries. Primaries quite 

 uniformly powdered, save that as a whole the costal region is somewhat 

 darker than the rest of the wing ; this feature being most obvious in the 

 male now before me. All the markings present, but not well defined. 

 Basal Hue geminate, smoky, fairly well marked on costa, but obscure 

 below. T. a. line geminate, smoky, the inner portion scarcely defined 

 below the median vein, its course straight to that point, thence outcurved 

 *o the submedian and again below it. T. p. line lunulate, geminate, 

 smoky, the included space paler gray, only a little sinuate and as a whole 

 parallel with the outer margin. A vague median shade line, most 

 obvious between the ordinary spots and very slender below them. 

 S. t. line pale, irregular, broken, defined by irregular black preceding- 

 blotches or spots which are the largest on the costa opposite the cell and 

 in the sub-median interspace. A series of interspaceal, black, terminal 

 lunules, beyond which is a pale line at the base of the fringes. The 

 claviform is small, concolorous, defined by black scales. Orbicular large, 

 ovate, of the ground color, somewhat incompletely black-ringed. Reni- 

 form large, kidney shaped, with a smoky outline, inwardly marked by 

 paler scales and a more or less obvious dusky central lunule. Secondaries 

 smoky, a little paler at the base, with a dusky, followed, by a paler extra 

 median line, a dusky discal lunule and a blackish line at the base of the 

 fringes. Beneath, primaries dusky, terminal space pale powdered, with 

 or without a dusky and paler extra-median line ; secondaries white, 

 powdery, with a median line and dusky discal spot. 



Expands 1.80-1.90 inches = 45-47 mm.

One male and one female from Mr. A. W. Hanham, who has 

 other similar examples. The specimens were in excellent condi- 

 tion when shipped, but suffered in transit. I was at first inclined 

 to consider this a dark nimbosa, but found afterward that this 

 could hardly hold. It is somewhat intermediate between that
