Beneftth largely blackish, without marks ; the apices and costal region and 

 the fringes of both wings pale yellowish. 



Expanse, 18 m. m. A single specimen on flowers in July. Cen- 

 tral Alabama. Collection of this Society. 



The fore tibiae are provided with a double row of spines, ter- 

 minating in longer claws; the other tibiae appear to me unarmed.

Heliotliis suetus, Grote, Plate 3, fig. 10 5 . 



^ . — Ocelli ; eyes naked ; antennae simple, scaled above, pilose beneath. 

 Body clothed with pale sericeous olivaceous hair. Fore wings dull purple, 

 equally overlaid with pale sericeous scales. No traces of ordinary lines. 

 Below median nervure, between the inceptions of veins 3 and 3, an even 

 nearly white band descends straightly to internal margin. Above median 

 nervure a whitish discal blotch takes the place of the orbicular and a second 

 broader, at the extremity of the cell, the place of the reniform. These two 

 discal demi-bands seem on either side continuous with the inferior band 

 which hence has a furcate appearance. Terminal space paler than the rest 

 of the wing, wanting the purple color, and indicating, by contrasting, a sub- 

 terminal line. Hind wings black with a broad median fuscia interrupted 

 medially and thus forming two large spots, the lower subquadrate, the upper 

 ovate ; fringes white. Beneath, largely Avliite ; costal edge of primaries 

 white ; the deep black basal patch not attaining costa ; a large subquadrate 

 black discal spot ; transverse line indicated and followed by a large diffuse 

 blackish shade inferiorly. Hind wings largely whitish ; the black basal 

 patch does not attain costa and partly absorbs the large discal spot. The 

 wide, hind border is abbreviated. 



Expanse, 23 m. m. Habitat, Colorado Territory (coll. Theo. L. 

 Mead, No. 7). 



Resembles the European H. purpurascens, but is more faintly 

 colored and the band of the fore wings is single inferiorly. 



Heliotliis persimilis, Qrote, Plate 3, fig. 11 ? . 



$ . — Perhaps the opposite sex or a variety of H. siietun. It differs as 

 follows: smaller and with olivaceous scales margining the median fascia
