Posterior wings and fringes very pale fuscous. 



Expanse, 25 mil. 



Habitat. — Xew York, Massachusetts, (Sanborn), 



CONCHYLIS Treitschke. 

 Conchylis agaasizii, n. s. (Plate viii, fig, 75.) 



Head and palpi white, the latter slightly tinged laterally with brown. 

 Thorax brovrnish-olivaceous; patagia pure white. 



Anterior wings dai'k olivaceous-brown with lustreless silvery white 

 markings. Beyond a narrow white costal spot a larger patch of white 

 scales rests on the middle of costa and runs thence very obliquely out- 

 wardly halfway to external margin, where it is separated from a simi- 

 lar spot which runs obliquely to costa just before the apex of the wing. 

 These spots enclose a circular white dot on costa. An irregular white 

 stripe commencing at the base runs irregularly through the central 

 portion of the wing to just before external margin ; it is narrow at its 

 origin, constricted at basal third and again beyond the middle, where 

 it curves down towards internal margin. On external margin above 

 the end of the stripe a white spot with a few dark central scales, and 

 a small white spot or dot on internal angle. The internal margin is 

 narrowly white to end including a white patch before the middle. Un- 

 der a lens the markings are found to be margined narrowly by blackish 

 scales. Fringes white except a narrow fuscous tinge just below the 

 middle. 



Posterior wings fuscous. Fringes white. 



Expanse, % 23 mil. 



Habitat.— Wvico Co., Texas "May 17th." (G. W. Belfrage). 



Conchylis quinquemaculana, n. s. (Plate viii, fig. 76.) 



Palpi, head and thorax pale browuish-ochreous; patagia tinged with 

 silvery. 



Anterior wings dark brownish-ochreous with five shining silvery- 

 white maculations. The first spot, at the base, is small and does not 

 attain either margin ; the second commencing narrowly on costa before 

 the middle, is broadest centrally and narrowest on internal margin run- 

 ning entirely across the wing. The third spot large, rounded, rests on 

 costa beyond the middle, narrowly separated from the fourth which is 

 smaller and placed just within internal angle. The fifth spot is small 

 nearly round, and is placed on the costa just before the apex. All these 

 spots are narrowly margined with dark brown scales, and the veins of 

 the wing are similarly marked beyond the third and fourth spots. 

 Fringes pale fuscous, the ends of the scales blackish.
