m. nervules and strongly dentate on submedian fold. The pale ocliery follow- 

 ing shade is narrow but widens on costal region, following the sinuosities of 

 the line. The subterminal dark shade is medially extended along the veins 

 into the ocliery terminal shade which is here broader. There is a dark ter- 

 minal line on both wings and the fringes are dusky. On the hind wings there 

 is a narrow median yellow band and the deep yellow color appears subcontin- 

 uously and narrowly along the terminal margin. There are some yellow 

 scales on the disc defining the discal dot. Beneath more entirely yellow, es- 

 pecially the hind wings, with the dusky lines and discal spots well defined, as 

 well as the subterminal shades; fringes as on upper surface. Body, dusky ; 

 abdomen subannulate above with yellowish, beneath pale yellowish.

Botis liircinalis, n. s. 



This species is allied to the European B. opaealis of the Alps, and B. aerealis 

 of the plains. It difl^ers from the former in the width and shape of the shade 

 band of the primaries. Fore wings bright olivaceous over black, without 

 markings except that the narrow pale ochery shade which follows the exterior 

 line is here alone apparent, comparatively narrow, more sinuous than in opa- 

 ealis and less diffuse, showing that the exterior line has a different conforma- 

 tion in the American species. Fringes blackish with pale tips. Hind wings 

 unicolorous blackish, fringes paler, whitish outwardly. Head and collar deep 

 ochery ; thorax olivaceous. Beneath pale ochraceous, primaries mostly dusky ; 

 hind wings with subterminal and discal dusky shades not rayed as in opaealis.

Botis niveicilialisj n. s. 



A blackish species allied to Mreinalis, with pointed apices to the primaries 

 and snow white fringes to both wings. Fore wings concolorous dusky black- 

 ish, with the exterior line and discal dot very feebly indicated. The line is 

 however followed on costal region by a yellowish shade which becomes the 

 most conspicuous feature of the ornamentation of the wing. Beneath both 

 wings black with a faint indication of the costal shade. At the base of the 

 fringes a faint yellow stain may be noted. Body blackish ; the abdominal 

 segments very narrowly edged with pale ; beneath paler, whitish.
