 der surface of primaries blackish ; costal region and external margin 

 shaded with purplish scales; an arcuate blackish transverse shade 

 band, beyond which a second, fainter, and followed on costa before the 

 apex by a few whitish scales; between these two lines on costa are two 

 pale dots ; the terminal space is very pale purplish. Secondaries with 

 the costal I'egion and external margin thickly irrorate with pale pur-

Size of H. nictitans, and is readily distinguished from either that 

 species or H. lorea, by its darker color, the shape of the reniform spot 

 and the excavate fringes. In the extensive Collection of Mr. Gruenee, 

 at Chateaudun, are specimens of this species which we have been able 

 to compare with our material, owing to the kindness of this distinguish- 

 ed Entomologist. 



XANTHIA, Ochs. 

 Xanthia ralla, n. sp. (Plate 7, fig. 49, % .) 



% . Ochreous-yellow. Size moderate ; form slight. Head and tho- 

 rax concolorous, ochreous-yellow; antennae testaceous. ^Abdomen 

 somewhat flattened, dull pale ochreous beneath. Eyes small, conical, 

 black ; maxillae rather short, testaceous ; labial palpi short, not ex- 

 tending beyond the front. Legs ochraceous, paler inwardly; under 

 thoracic squamation dull pale testaceous. 



Anterior wings dark ochreous-yellow, transverse lines blackish, bro- 

 ken. A faint basal half-line. The blackish transverse anterior line 

 is geminate, the lines widely separate, the outer paler and indistinct. 

 It is perpendicular and a little irregular, preceded by a blackish dot at 

 the base of the discal cell. The orbicular is very faint, merely out- 

 lined, ovate, the annulus including a blackish dut infcriorly at median 

 nervure, which is usually perceivable even when the annulus is obsolete. 

 The median shade is prominent, slightly irregular and nearly perpen- 

 dicular, running approximate to the reniform spot. The latter is of 

 the normal shape, obsoletely outlined, the inner pale annulus including 

 three or four black dots inl'eriorly (of which that on the inner side of 

 the spot, situate in the outer and lower angle of the discal cell, is usu- 

 ally the most prominent) and one or two superiorly. The transverse 

 posterior line is geminate, the outer of the two lines composing it the 

 most distinct, very slightly arcuate superiorly, slightly inwardly sinu-
