74 JOHN B. SMITH. 



broad included space. T. a, line upright, with an outward angulation in each 

 interspace. T. p. line with a rather even, broad outcurve over the cell, below 

 which it is slightly incurved. S. t. line faint, narrow, very slightly paler, or 

 marked only by the very faiut contrast between the terminal and s. t. spaces. 

 A faintly paler line at base of fringes. The claviform is concolorous, moderate, 

 outlined by the same brown of the median lines, by which also the ordinary 

 spots are defined. Tiie latter are more yellow, somewhat concolorous ; the or- 

 bicular small, round, the reniform upright, broad, slightly constricted medially. 

 Secondaries more yellowish, more fuscous in the male, slightly darker outwardly, 

 fringes paler. Beneath, more yellowish, with pink powderings, immaculate. 

 Expands 37-38 mm. : 1.48-1.52 inches.

The thoracic vestiture is somewhat loose, there is a small kael-like 

 dorsal tuft, and in the male the antennpe are furnished with lateral 

 tufts of bristles; but the joints are scarcely produced. 



The species has a very strong superficial resemblance to Fachnobia 

 2)ectlnata Grt. {feryuginoides Smith), save that is larger and paler, 

 and of course has other generic characters. Both sexes are before 

 me ; in the female the ovipositor is somewhat extruded and the 

 valves are double, 



Hy<lreecia niedialis n, sp, (PI. i, row 1, fig. 5) — Ground color varying 

 from a rusty Uiteous to a reddish gray over yellow, the median space of the pri- 

 maries contrasting, deeper brown. Head and thorax concolorous, immaculate. 

 Basal line wanting, T. a. line narrow, single, slightly paler, outwardly oblique 

 to the middle, then straight to the hind margin. T. p. line distinctly palei', 

 single, with a long outcurve on the costa, then almost rigidly oblique to the hind 

 margin, so that at this point the median space is rather more than one-half as 

 wide as it is on the subcostal vein. S. t. line obsolete, the terminal space dark- 

 ened somewhat by brown powderings. A paler terminal line at the base of 

 fringes, which are rather darker than ground color. The ordinary spots are 

 somewhat vaguely defined in the dark median space, and sometimes almost ob- 

 solete. When they are best marked they are slightly paler than the surrounding 

 brown and narrowly brown ringed; both of moderate size, the orbicular oval, 

 oblique, the reniform kidney-shaped. The claviform is wanting in the speci- 

 mens I have seen. Secondaries yellowish, powdery, somewhat darker outwardly, 

 fringes with a rosy tinge. A somewhat indistinct median line. Beneath pale, 

 with reddish powderings. A dull fuscous outer line and a discal luuule on all 

 the wings. Expands 43-45 mm. ; 1.72-1.80 inches.

This species is easily recognized by the contrasting dark median 

 space, in this unlike obliqua, which it otherwise resembles most nearly 

 in appearance. Both sexes are before me, and other specimens are 

 in collections. I believe that Mr. Bruce took a number of specimens 

 some years ago ; but I have hesitated about describing it, fearing 

 tluit it might be one of the species with which I was not acquainted.
