BULLETIN OF THE BROOKLYN ENT SOC. 43 



Fore wings crossed with three distinct brown lines, beginning equally distant 

 from each other on costa, and approaching each other at posterior margin; the 

 first and second more closely than the second and third. Nearly half way from 

 costa across the wing the outer line deepens in color to a black spot, and just be- 

 yond this are two black dashes very close to each other and lying lengthways at 

 right angles with the line. Middle line with a prong starting out from it near 

 the costa and extending about a line towards exterior angle; this prong represents 

 the discal spot. 



Hind wings with discal spot decided; a brown line running half way across 

 wing from the inner margin; outer edge slightly angulated. 

 Underneath, as above, with discal spots more distinct- 

 Ten specimens. Colorado. 



This species seems subject to considerable variation in the defi- 

 niteness of the lines crossing the wings. 



6. Rumia baltearia, sp ; nov. 

 Expands 14 lines. 



Body and wings sulphur yellow, lighter towards b&se on hind wings. 



The fore wings have a broad band of brown occupying one-fourth their area in 

 length; this is angulated outwardly on its inner margin, and waved outwardly 

 and irregularly on its outer margin. It extends at an almost uniform width half 

 way across the wings, then suddenly becomes reduced in width, and thus extends 

 to posterior margin. 



Hind wings with indistinct line of brown. 



Four specimens. Minnesota and Colorado. 



This is undoubtedly near to Rumia sulphuraria, Pack., and I am 

 not confident it is not a variation of that species ; but the broad 

 brown band gives it a decided individuality of appearance, and I 

 have been able to see no connecting intergrades. 



7. Marmopteryx dryadata, *p. nov. 



Expands 14 linos. 



Antenna? and palpi light russet. Body somewhat pronounced russet ; ante- 

 rior part of abdomen white beneath ; surface of wings smooth and silky, gen- 

 erally light russet in color. The color more pronounced on costal area and outer 

 edges than on discal area, where it fades nearly to white. 



Fore wings with a broad, indistinct, whitish band, beginning about three- 

 fourths of distance from base to apex, and running parallel to the outer edge till 

 it is lost in the discal area. Another very indistinct band begins at the apex, 

 and, running inwardly, extends nearly to the previous line, forming an oblong 

 patch. Fringes checkered with white and brown. 



Hind wings with broad, bent, indistinct white band about the middle of 

 the wing and an indistinct white spot at middle of basal area. Fringes check- 

 ered with white and brown. All the wings narrowly edged with reddish 

 brown on external margin.
