Packard.] 58 [October 17, 



and one in the middle of the wing. This is succeeded by a darker 

 band, and a broad, lighter space ; on the outer fourth of the costa is 

 an oblique band of even width, which crosses to the internal angle ; 

 in the middle of this white band is a narrow linear projection in- 

 wards under the subcostal. This band varies in sending in an acute 

 point, or a simple linear elongation, and the white band may extend 

 to the apex ; it is marked on the costa, with three black dots. Hind 

 wings cinereous as usual, more dusky at tip, fringe whitish, with two 

 dusky lines at the apex, as on the fore wings. Beneath, uniformly 

 dusky cinereous, costa on the outer half spotted with white and black, 

 the three white spots at the apex being pupilled with black. Hind 

 wings jialer. 



Length .30 ; fore wings .30 inch. 



A common species, and closely allied to P. glaciana, but it is 

 smaller, with narrower wings. The whitish line at the base of the 

 fore wing is often obsolete, and the basal three-fourths of the wing are 

 very uniform. It also differs in the outer white band, which varies 

 greatly in shape, in being dentate inwards, not having the simple 

 flexure inwards on the median that is present in P. glaciana. 



Penthina tessellana n. sp. 



3,9. Cinereous with black patches and dots. Head and thorax 

 dark, with whitish scales. Head blackish on the vertex, front paler, 

 palpi dark, paler beneath ; tips of second joint very square, truncate ; 

 third joint minute, acute, depressed. Fore wings checkered conspic- 

 uously on the costa with black, irregular bands and spots ; a basal 

 black band, growing pale inwards, with its outer edge irregular, en- 

 closing a conspicuous white spot on the submedian vein ; towards the 

 costa, the edge becomes obli(]^ue, directed inwards on the costa. Be- 

 yond is a broad whitish baud flecked with dark scales, which enclose 

 a black dot on the costa. In the middle of the wing is a broad black 

 band, limited on the costa, but below the middle of the wing formed 

 of detached black patches, three in number, the outer one being near 

 the internal angle. Beyond, on the costa, are three black checks, or 

 square spots, alternating with white, the extreme apex is black, with 

 a larger diffuse black conspicuous spot surrounded with white, this 

 diffuse spot in the 9 connects with the spot near the internal angle, 

 forming an oblique submarginal line ; edge of the wing dark, enclos- 

 ing three white spots, which in fresh specimens form a short wavy 

 white line; fringe uniformly dusky-brown, often interrupted with 

 white. There is above a conspicuous white sjjot in the angle of the 

 middle of the outer edge of the middle band. 



Beneath, cinereous, checkered on the costa, hind wings paler. Legs 

 cinereous, tarsi darker, ringed with whitish.
