AMERICAN LEPIDOPTERA, 343 



tate at costa, arcuate from subcostal to internal nervure, thence again 

 outwardly but more rouudedly projected to internal margin. Median 

 space clouded centrally superiorly with reddish scales. Orbicular spot 

 white, elongate, annulate with dark scales, moderate in size. Below 

 the median nervure the intermediate and claviform spots are fused 

 and form one modei'ate ovate white spot, annulate with black and 

 smaller than the orbicular. Median shade-band shaped as usual, dif- 

 fuse. Reniform peculiar in shape, being extremely attenuate and out- 

 wardly oblique ; it is elongate, widening slightly inferiorly, and pure 

 white, not resolved into distinct spots, annulate with dark scales. Trans- 

 verse posterior line very distinct, consisting of two lines (of which the 

 outer is deeper colored and most ditfuse), roundedly arcuate over the 

 nervules superiorly, thence running slightly inwardly obliquely to in- 

 ternal margin. Subterminal space darker than the rest of the wing, 

 purplish, margined outwardly by the irregular and dentate subterminal 

 line, which appears as the dark uneven edge of the space ; three pale 

 separate dots on costa. Terminal space concolorous with median, deep 

 yellow, below the apices more or less irrorate and shaded with reddish 

 scales on the interspaces. Secondaries entirely pale rosy-purple, be- 

 coming faintly and narrowly paler before external margin ; traces of 

 the usual transverse subterminal shade and internal line, but, owing to 

 their general dark color, the secondaries appear immaculate ; fringes 

 concolorous with the wing, tipped with a paler shade. Primaries be- 

 neath washed with pale rosy purple over the disc, irrorate with simi- 

 larly colored scales on the margins, and becoming testaceous or pale 

 cinereous along internal margin and at base; traces of two parallel 

 transverse subterminal shade lines. Secondaries testaceous cinereous, 

 rather thickly irrorate with pale rosy purple scales, especially superi- 

 orly ; a distinct transverse shade line and fainter subterminal shade; 

 fringes less purplish than on upper surface.

 This fine species is, perhaps, the largest North American represen- 

 tative of the genus. It varies but slightly in the distinctness of the 

 ornamentation. From (}. purpurifascia and Gr. rutila, it differs by its 

 smoother squamation, heavier form, the peculiar attenuate shape of the 

 white reniform spot, the even coloration, more distinct ornamentation, 

 and the rosy-purple tinge of the secondaries above and wings beneath, 

 this latter character reminding us of the species of Nephelodes, G7i. 

 From G. purpurifascia it is easily separated by the course of the trans-
