no. 1G45. REVISION OF CERTAIN NOGTVIDM— SMITH. 217 



Lunifera is the best marked of the species, the t. p. and s. t. lines 

 being black, and the double extra-median line of the secondaries also 

 black. The tendency on both wings is to a black filling between 

 these lines, so as to form a more or less distinct band, and some- 

 times a black shading extends prominently into the median area. 



Lineosa has none of this contrasting maculation and the lines are 

 only blackish or brown. Sometimes it becomes a matter of nice judg- 

 ment as to just where to place a given individual, well marked Ihieosa 

 and flown lunifera overlapping in either direction. Structurally the 

 species are alike or nearly so, yet T believe them to be distinct. 



Unilineata stands by itself in several points. From all the preced- 

 ing it differs in the greater simplicity of the maculation, lacking 

 the predominating transverse .fasciation, and in this it agrees with 

 the immediately following species. The t. a. line, however, is even, 

 without angulation below the costa, and the s. t. and t. p. lines are 

 united into a single line below vein 7. The outer margin also is 

 much more strongly denticulated than in the other species, so that 

 with its rusty grayish brown color we have a form that is recogniz- 

 able at all times. 



The next series of nine species have the wing form somewhat less 

 triangular than in the typical lunata type. The primaries have the 

 costa more arched at base, and the apex is rectangular rather than 

 pointed. The transverse fasciation is much less marked, and the 

 extremely oblique character of the markings is modified into a tend- 

 ency to become almost upright. The t. a. line is single, forms an 

 acute outward tooth on the subcosta. is strongly drawn back on that 

 vein, and then is almost upright in general course to the inner mar- 

 gin. The t. ]). line is outwardly bent over the cell, more or less in- 

 dented or drawn in opposite the reniform so as to make an upright 

 W, and is then incurved again on its course to the inner margin. 



The largest of these species is obliqua, in which none of the mark- 

 ings are well defined or strongly contrasted, and there is a uniform 

 bluish or violet powdering over the pale brown ground. The reni- 

 form is not or only a little darker, and altogether this is a very hand- 

 some species without any very positively marked characters. 



Metata is a smaller, better marked specie-, which lacks the hoary 

 appearance and has the reniform black or at least dusky. 



In curema the t. a. line is black, as it is in the two next following 

 species as well; the color is a darker, very smooth even brown; the 

 median shade is scarcely marked and the reniform is black and 

 contrasting. 



Helata is a somewhat rougher, better marked species, the median 

 shade more defined, the t. p. and s. t. lines much better marked, and 

 the s. t. space darker than the rest of the wing.
