forming a right angle on the submedian nervure, above rounded, and 

 on the outside deeply excavated. Median shade dark, extending 

 obliquely, close to the reniform spot, to the exterior line, then turning 

 and continuing parallel to the latter to the inner margin. Exterior 

 line incompletely geminate, denticulate above, subparallel to the ex- 

 terior margin. Terminal and subterminal spaces of a slightly bluish, 

 olivaceous cinereous. Subterminal line white, preceded between 

 the median branches by four very conspicuous, black, cuneiform 

 marks, and followed by more or less distinct, olivaceous spots. Up- 

 per portion of the subterminal space olivaceous, contrasting with the 

 subterminal line. A series of black, triangular spots at the base of 

 the fringe, which is dark, cut with light. Posterior wings fuscous, a 

 black line at the base of the yellow fringe. Beneath, the anterior 

 wings are dark gray, the reniform spot and the upper portion of the 

 exterior line reproduced in black. Costa and terminal space light 

 gray. Posterior wings whitish with a distinct discal dot. Traces of 

 a median and terminal shade line. 



Hab. Cambridge, Mass., July 17. From my collection. 



Very strongly marked, but the colors are not so clear and unmixed 

 as in the previously described species. The peculiar shape and color 

 of the reniform spot, the submedian dash and the subterminal cunei- 

 form spots are prominent markings, and will distinguish it. 



Polia confragosa nov. sp. 



Expanse 44 mm. Length of body 20 mm. 



The eyes are naked, with strong lashes. The antennae are shortly 

 bipectinate. The collar is cut out and produced in front. • A fur- 

 rowed, prothoracic tuft. The metathoracic tuft is not present on 

 this specimen, but it may have been accidentally destroyed. Abdo- 

 men tufted. On the anterior wings the markings are very distinct 

 and contrasting, as is usual in this genus. The colors are black, 

 white, gray, and ochreous. The half-line distinct. A short basal 

 streak, accompanied by a broad blackish shade. The basal space is 

 white, more or less diffused into ochreous, an ochreous shade extends 

 along the inner margin. The interior line is very oblique, geminate, 

 its inner line fine, the outer one black and distinct, forming a long 

 tooth on the submedian nervure, the point of which connects with 

 the exterior line. The median space is gray, broad above, much nar- 

 rowed below. The ordinary spots are large, disconcolorous and very 

 conspicuous, the orbicular is rounded, slightly ochreous, having a 

 central gray spot; the reniform is much excavated outwardly, white,
