30 JOHN B. SMITH. 



throufihout. Orhictilar subquadrate, ol>lique, not extending below tbe median 

 vein in my examples, sometitiies narrowly outlined by black scales, sometimes 

 marked by the slightly paler color. Reniform of moderate size, constricted cen- 

 trally, larger infeviorly and dusky filled by the median shade, not well defined, 

 obscui'ely annulate with a somewhat paler shading. Secondaries very pale smoky 

 with a faintly reddish tinge, fringes whitish, veins and a discal spot larger. Be- 

 neath gray, powdery, with discal spots, of which those on the secondaries are the 

 larger. 

 Expands 39-45 mm. = 1.56-1.80 inches. 



Hab. — Canada ; New England States ; Northern New York and 

 Pennsylvania; Colorado. 



Both sexes are at hand and similar in appearance, male antennae 

 thicked and obviously ciliated. The variation consists in the 

 amount of smoky shading and the consequent distinctness of the 

 markings. In the paler forms the median shade is quite obvious, 

 in the darker forms it is lost. 



Xyliiia piiella n. sp. 



Head, thorax and primaries very pale gray, almost whitish. Secondaries pale 

 smoky, with a yellowish tinge, the fringes white. Abdomen with an obscure 

 suggestion of reddish. Head with smoky frontal line. Collar with a blackish 

 line below the tip, surmounting a slightly reddish tint. Thoracic crest low, not 

 divided. Patagite with blackish line at base of wings. Primaries with the 

 markings cleanly written. A slender black streak at base through a dusky shad- 

 ing, above which the space is almost white to costa. Basal line geminate, marked 

 on the costa only. T. a. line geminate, the outer defining line black, inner smoky, 

 as a whole nearly upright, irregular, with moderate teeth in the interspaces. S. 

 t. line geminate, inner portion lunate, black or blackish, outer portion even, 

 smoky, as a whole nearly parallel with outer margin after the usual outcurve 

 over cell. S. t. line marked by a series of trigonate smoky spots and by a smoky 

 costal shading. A series of smoky terminal lunules. Median shade smoky or 

 blackish, diti'use, outwardly bent between the ordinary spots, slightly darkening 

 tbe lower part of reniform, then close to and parallel with t. p. line to hind mar- 

 gin. Claviform small, black ringed, concolorous. Orbicular black ringed, oval, 

 extending well below the median vein. Reniform black lined, upright, of good 

 size, oblong, a little heel extending backward toward the orbicular. There is a 

 yellowish or reddish central flush, else both spots are paler than the ground. 

 Beneath whitish, powdery, primaries a little darker centrally, all wings with a 

 large, blackish, discal spot. 



Expands 42-44 mm. = 1.68-1.76 inches. 



Hab. — California. 



Two female examples without more definite locality. From all 

 the iujinediately preceding forms it differs in the tolerably even 

 median lines and in the obvious claviform, while from the antennata 

 series, to which the general maculation refers it, the slender black 

 streak will serve to distinguish it.
