NORTH AMERICAN NOCTUIDAE— SMITH AND DYAR. 65 



or nearly so, powdered, with a more or less obvious outer line and 

 discal spot. 



Expanse, 1.25 to 1.80 inches (32 to 45 mm.). 



Habitat. — Colorado, without date or definite locality; Miles City, 

 Montana, June 3. 



Five males and two females are at hand for comparison. The species 

 is most nearly like Icpusculina; but it difiers by the much darker ground 

 color, the somewhat narrower and njore powdery primaries, while the 

 transverse posterior line is continuous in all the specimens. The harpes 

 are narrower and more i)ointed than in its ally, and the clasper is (piite 

 stout and well developed. The front is moderately bnlging, but not 

 prominent. The palpi rea(;h to its middle and in leg structure it does 

 not differ apparently from lepusculina. 



ACRONYCTA TRANSVERSATA, new species. 

 (Plates X, fig. 10, iiialo adult; XX, fig. H, male genitalia.) 



Ground color ashen gray, distinctly and quite densely black pow- 

 dered. The head and thorax are, as usual, without markings except 

 for a black line reaching to the base of the primaries from the sides of 

 the palpi. The ordinary maculation is more or less distinctly traceable 

 in all the si)ecimens before me, though never quite complete. The basal 

 line is marked by a black spot on the costa. The transverse anterior 

 line is niarked by a black spot on the costa, which is sometimes double, 

 by a pairof angulated marks below the cell, and by one or two lunules 

 on the inner margin. In one case the connection between these spots 

 and marks is almost complete, so there is nearly a full transverse ante- 

 rior line. The median shade is marked by a blackish spot on the costa, 

 extending obliquely to darken the reniform, thence abruptly bent and 

 running parallel with the transverse posterior line to the inner margin. 

 The transverse posterior line is well marked, (continuous, narrowly lunu- 

 lated, more or less obviously marked opposite the cell, where there is 

 usually a distinct dagger. The line is black shaded opposite the 

 internal angle, and there is an evident dagger crossing it. The termi- 

 nal space is darker than the rest of the wing, and there is a series of 

 small terminal dots, beyond which the fringes are cut with black. The 

 black streak at the base is distinct and extends without break from 

 the base to the transverse anterior line. The orbicular is round, or 

 nearly so, black ringed. The reniform is indetined and dusky. Sec- 

 ondaries white, or nearly so, in the female outwardly soiled. Beneath 

 whitish, with a more or less complete outer line, and an obvious discal 

 spot on all wings. 



Expanse, l.GO to 1.80 inches (40 to 45 mm.). 



Habitat. — Colorado, no date or special locality. 



Three males and one female of this species are at hand, and it differs 

 obviously from all tliose that have preceded it by the complete median 

 shade line. It is also somewhat darker than any of the other species,
