PSYCHE [June 



Xylina vertina, n. sp. 



Ashen gray with a bluish tint, more or less powdery. Head with smoky and black 

 powderings, with a black frontal line. Collar a little brownish at base, to a narrow black 

 median line, above which is a distinct white edging. Patagia with a black line at base of 

 primaries. Abdomen a little rufous. Primaries with the veins narrowly black marked, the 

 entire surface a little mottled, smoky along the costa, the distinct outwardly angled smoky 

 median shade forming the most obvious character. There is a slender black basal line. T. 

 a. line geminate, the two parts widely separated, black, dentate, distinct only from costa to 

 median vein, the outer part touching the orbicular, a long tooth marking its termination on 

 the inner margin. T. p. line geminate, marked in the costal area only. S. t. line marked by 

 a series of sagittate black spots. There is a series of small black terminal lunules. The 

 median shade is smoky, diffuse, outwardly oblique from costa so as to darken the reniform, 

 then inward so as to reach the inner margin at about its middle. Orbicular round or ovate, 

 of good size, a little paler, narrowlj' outlined by black scales. Reniform large, upright, 

 centrally somewhat constricted, dilated inferiorly, incompletely outlined, darkened by thq 

 median shade and by a powdering of rusty scales. Secondaries smoky with a reddish tinge, 

 a little darker outwardly, fringes whitish. Beneath, primaries smoky, with a reddish pow- 

 dery terminal area and a blackish round discal spot. Secondaries reddish, powdery, with a 

 smoky discal lunule. 



Expands i. 75-1. 9a inches = 44-4S mm. 



Habitat: Corvallis, Oregon, September 8, at light; Biitish Columbia — no date. 



Two males in good condition. The species belongs to the georgii series, differing from 

 them all in the more elongate primaries, the confused mottling, and the very distinct median 

 shade. Incidentally it may be noted that all the species of this series have a black line on 

 the outer side of the hind tibia. 



Xylina merceda, n. sp. 



Ground color a deep ashen gray witliout any reddish admixture. Head and thorax 

 almost mouse gray, a little powde'"y, collar with an obscure transverse line. Primaries with 

 all the maculation present, not well written, only the paler orbicular standing out in 

 any relief whatever. There is no black line, streak or dash at base. Basal line marked 

 only on costa by geminate blackish lines which tend to become lost. T. a. line geminate, 

 blackish, tending to become lost ; irregular, variably outcurved in the interspaces. T. p. 

 line geminate, vague at best, inner line lunulate, almost crenulate, outer a mere shadings 

 irregular; but as a whole nearly parallel with the outer margin. S. t. line consists of a 

 som.ewhat irregular dusky shade, more or less broken up into triangular, hardly sagittate 

 spots, outwardly marked by whitish scales. A series of blackish terminal lunules tends to 

 become obsolete. There is a diffuse, obscure median shade angulated on the reniform. 

 Claviform very small, loop-like, not always traceable. Orbicular oval, oblique, large, with a 

 submedian annex, paler than the ground and with blackish margins. Reniform large, up- 

 right, a little constricted, margined by black scales within which is a somewhat paler annu- 

 lus. Secondaries dull whitish or yellowish at base, darkening outwardly to the whitish 

 fringes, markings of imderside faintly reproduced. Beneath, primaries smoky, with a pow- 

 dery pale terminal area: secondaries pale, powdery, with a hioad outer shade line and a ilark 

 discal lunule.
