the median and subniedian nervures. To this lobe the small black 

 claviform spot is attached. Median space overspread with gray ; the 

 median shade blackish and diffused. Reniform and orbicular spots 

 white, broadly encircled with black; the former lunulate, the latter 

 nearly round. The exterior line of the usual shape, acutely inwardly 

 dentate between the nervules, followed by its lighter component line; 

 the space between them clear white. The subterminal line a blackish 

 diffused shade, preceded by a series of clear black subcuneiform spots. 

 Those opposite to the cell and below the median nervure the most 

 prominent. A series of conspicuous triangular spots at the base of 

 the fringe. The latter is black, cut with white opposite to the trian- 

 gular spots. Posterior wings gray, having a distinct discal dot and 

 median band. An interrupted black line at the base of the fringe, 

 and a darker subterminal shade band. Beneath gray. On the an- 

 terior wings the ordinary spots, the exterior line, and the cuneiform 

 spots are reproduced in black, somewhat less distinctly than above. 

 The posteriors with a very distinct discal dot and median band.

Taken at the camp of the Entomological Club, a short distance 

 below the Half Way House, July 6, 1874. 



A very distinct species. Allied to Polia leucoscelis Grote, from 

 Wisconsin, from which it can be separated by the absence of a con- 

 necting line between the exterior and interior lines, and also of the 

 cuneiform subterminal markings. It differs, besides, in other minor 

 particulars. 

 Polia speciosa nov. sp. 

 Expanse 45 mm. Length of body 20 mm. 



Eyes naked, lashed. Basal antennal tufts. Collar and thorax 

 gray, the former rounded, with a central black line ; the latter smooth, 

 with only a short metathoracic tuft, tipped with black. Abdomen 

 smooth, untufted. On the anterior wings the median space is of a 

 dark, bluish olivaceous gray. A bifid, black, basal streak, its lower 

 branch short and thick, the upper fine, extending along the subcostal 

 nervure to the interior line. Half-line present. A very distinct, 

 thick, black dash beneath the subniedian nervure; between the 

 dashes the basal space is whitish. Interior line double, lobed be- 

 tween the nervures, the lobe beneath the submedian elongated. The 

 lines which compose the claviform spot thick and black. The ordinary 

 spots disconcolorous, edged with black, with olivaceous centres and 

 very distinct, yellowish-white annuli. Reniform spot large, irregular,
