NO. 1203. NEW NOCTUID MOTHS— SMITH. 473 



One pair only, the male in good condition save that it lacks anten- 

 na? 5 the female, which is much older, somewhat defective. The sj>ecies 

 has the wing form of theodori, bat differs utterly in maculation from 

 all others of the genus. 



Type.— Ga.t. Ko. 4820, IT. S.N. M 



72. POLIA DISPAR, new species. 



Grround color very pale luteous gray, almost white. Collar with a 

 faint, smoky line below the tip. Patagia with a submarginal, diffuse, 

 black line. Primaries with smoky powderings which obscure the ordi- 

 nary maculation. Basal line vaguely indicated by smoky marks on 

 the costa. Transverse anterior line hardly more obvious, but by patch- 

 ing together the scattered black scales, it is seen that the line is strongly 

 angulate in the interspaces, the tooth below the submedian vein almost 

 meeting one from the transverse posterior line. The tooth in the cell 

 takes the form of a black, angulate mark before the orbicular. A 

 short, slender, blackish streak from base to basal line in the cell and a 

 similar, more obscure streak along the inner margin into tlie tooth of 

 the transverse anterior line. Transverse posterior line somewhat better 

 marked but obscure, incomplete, with long, irregular outward teeth on 

 the veins, and long inward dentations in the interspaces; that in the 

 submedian being best marked. Median shade smoky, somewhat dif- 

 fuse, oblique from costa between the ordinary spots, then inwardly 

 bent from the lower angle of reniform. It is a little the best marked 

 feature of the wing. Subterminal line concolorous, marked by a series 

 of preceding, sagittate, smoky marks. A series of distinct, black, 

 interspaceal, terminal lunules, beyond which the fringes are cut with 

 smoky. Fringes a little dentate. Orbicular small, round, concolorous, 

 incompletely and very narrowly outlined by black scales. Eeniform 

 large, upright, a little kidney-shaped, obscurely annulate with yel- 

 lowish, a little darkened by the median shade interiorly. Secondaries 

 in the male white, immaculate; in the female with smoky veins, a smoky 

 terminal line and smoky powderings toward anal angle where an 

 extra median dusky line is well indicated. Beneath white or nearly 

 so with small discal spots, much less obvious in the male. 



Expanse, 42 (male) to 45 (female) mm. = 1.68 to 1.80 inches. 



Habitat. — (jlenwood Springs, Colorado, October 1-10 (Dr. Barnes). 



One pair, both fairly good examples. The male has the antenna^ ser- 

 rated and bristle tufted. The primaries are a little broader and more 

 pointed than usual in the genus, and the species is much more obscurely 

 marked. Yet, so far as the maculation is traceable, its dentate char- 

 acter fits well into the series in which I have placed it. The very light 

 color separates it from all save ochracea, and from that species, the 

 white secondaries of the male and the totally different ordinary spots 

 will distinguish it.
