This line and the large discolored orbicular are the most promi- 

 nent characters of the insect. 



The antannae of the male have the joints with short pointed 

 teeth, which are furnished with tufts of stiff hair. The genitalia 

 have the harpes simple, with oblique tip, inwardly fringed with a 

 row of spinules. The clasper is double, arising from the middle 

 of the harpes and consists of a short twisted, somewhat spatulate 

 process, below which arises a longer, evenly curved, pointedclaw. 



In this character the new species agrees with gussata and 

 segregata, which in turn are much more closely allied than I had 

 suspected. It seems also that, either there is yet another species 

 or the one now described has a considerable range of variation. 

 A female specimen taken by Mr. Bruce in Garfield County, 

 Colorado, at an elevation of 6000 feet expands 43 mm., and is 

 therefore larger than any of the others. It is of a uniform fawn 

 gray with red- brown shadings in the median space, and all the 

 markings are well and uniformly written. There is none of the 

 dark suffusion seen in the other specimens, but every detail of 

 maculation agrees so far as they can be compared. It will 

 require a male of this particular form to decide the question. 



Mamestra neoterica n. sp. 



Ground color dull, red-brown. Head and thorax without obvious 

 markings, except that the patagiae may have a deeper brown submarginal 

 line. Primaries with a brighter, rusty brown shading which may be 

 visible all over the wing, over the basal and s. t. spaces only, or may be 

 entirely wanting. All the markings present but somewhat obscured. 

 Basal line short, black, geminate, carrying a few black scales to base from 

 its termination in the submedian interspace. T. a. line geminate, 

 obscure, the outer line blackish, the inner hardly deeper than the ground 

 color ; well removed from base, its course as a whole with a very even 

 outcurve. T. p. line rather evenly bisinuate, geminate, the inner portion 

 a little darker, feebly lunulate, the line as a whole rather defined by the 

 pale included space. S. t. line pale, very feebly marked, sometimes with 

 yellowish scales, sometimes scarcely traceable ; in course a little irregu- 

 lar. A smoky line is at the base of the concolorous fringes. A median 

 shade line is vaguely marked on the costa only. Clsviform more or less 

 black marked, usually well defined and extending nearly across the 

 median space. Orbicular ovate, somewhat irregular, outlined by black 

 scales within which is a series of white scales which hardly form an 

 anuulus. Renilorm moderate in si/e, concolorous or a little paler than 

 the ground color, more or less completely black ringed and also with a 

 rin- of whitish scales, which may, however, be entirely absent. Secon- 

 daries even dull fuscous. Beneath, primaries dull, smoky fuscous; 

 :udarirs paler, powdery, with a broken outer line.
