NATHAN BANKS. 37 



Wings broad, broadly rounded at tip; costal area very broad; radius and sub- 

 costa farther apart than usual and connected toward base by two veinlets; me- 

 dian not bent toward cubitus at connecting veinlet ; a veinlet connecting median 

 and first radial sector; four sectors, the fourth arising beyond the middle of the 

 wing, forked once before outer gradate series, other sectors simple ; last veinlet 

 of inner gradate series basad of next to last ; in hindwings the radial sector forks 

 before the forking of median. Expanse 12-16 mm. 



Specimens from Gowanda, New York (Van Duzee) ; Franconia, 

 New Hampshire (Slosson) ; Lakeluirst, New Jer.«ey (Torre Bueno) ; 

 Natrona, Pennsylvania ; Falls Church, Virginia, and North Caro- 

 lina. All taken during June or the last week of May. 



Borioinyiit specio!<«a Banks. — Head yellowish brown, darker above; 

 antennae pale yellowish ; thorax almost black ; abdomen dark brown; legs pale 

 yellowish. Wings hyaline, marked with dark brown, venation mostly i)ale, with 

 a few scattered brown dots, more brown toward margin of wing, apical half of 

 both anterior and posterior margins iiiterruj)tedly brown and yellowish, an indis- 

 tinct brown patch in costal area before the pterostigma, five or six almost black 

 dots along the radius, one at base of sectors, but first one beyond base of first .sec- 

 tor, and one under the pterostigma; another similar spot on cubitus where it is 

 connected to anal, a series of four or five obliquely across wing following the 

 first gradate series, the anterior one being on the first fork of the fourth radial 

 sector, and beyond is a crescent of five spots, most of them contiguous, on the 

 upper part of the second gradate series the posterior four of these are geminate, 

 with a minute white point, a larger triangular dark spot near end of cubitus and 

 anal veins. Hindwings with the costal neuratioii near middle and toward apex 

 distinctly brown, between it is very pale. The forewings are very broad, but 

 acute at tips; the costal area is very broad at base. There are four radial sec- 

 tors, but the first is rather peculiar, it arises nearer base than usual, at first 

 diverges but little, but curves before origin of second sector; none of the sectors 

 are connected back to radius; the median is not bent toward the cubitus at con- 

 necting veinlet. Expanse 15 mm. 



One specimen from Plummer's Island, ^laryland, September 9, 

 1903. A very distinct species on account of markings, and peculiar 

 first radial sector. 



BorioinyiA longifroiis Walk. — Face shining brown, vertex pale; an- 

 teuuse pale yellowish, darker at tips; pronotum pale, with brown stripes each 

 side, rest of thorax similar; abdomen pale brownish; legs pale yellowish, some- 

 times a darker band on anterior tibiae. Wings hyaline, forewing with mostly 

 brown venation, alternate white and brown spots around margin, an indistinct 

 band at gradate series and another toward base, a daik mark on posterior mar- 

 gin near middle, and a great many small brown marks from the veins. Hind- 

 wings with mostly pale venation, sometimes darker near tip. Anteuuse quite 

 long. Wings broad, especially the costal area near base; four radial sectors, or 

 if three, then the last is forked three times before outer gradate series, the first 

 sector connected back to base of second sector, the cubitus is forked several times
