metatlioracic tufts. The examination of perfect specimens will show 

 the actual size of this structure. Abdomen smooth above, with only 

 a slight basal tuft. Its coloration yellowish, with reddish lateral and 

 anal tufts; beneath, the abdomen is red. Posterior tibi as provided with 

 short yellow tufts. General color of the anterior wings light grayish 

 cinereous. On the costal region brown spots extend over the reniform 

 spot. Terminal space dark gray. All the lines and spots are present, 

 the former double ; the half-line indistinct, the space between its two 

 component lines whitish, forming a spot on the costa. Interior line 

 distinct, outwardly lobed between the nervules; its outer component 

 line clear and fine, the inner ill-defined and broad. Claviform spot 

 conspicuous, concolorous; orbicular oblique, elliptical, with a central 

 blackish shade spot; reniform large, clearly outlined in black, con- 

 stricted outwardly; within it is tinted with brown, and also contains 

 a blackish shade, which in the lower portion of the spot deepens in 

 color, forming a round black spot. Median space shaded with brown 

 above and on each side of the reniform spot. The median shade 

 forms a narrow shade line extending, parallel to the exterior line, to 

 the base of the reniform spot, where it turns obliquely, touching the 

 orbicular spot, and after that the costa. The black spots which ter- 

 minate the ordinary lines on the costa, alternate with the gray ground 

 color. The inner component line of the exterior line is most distinct, 

 and forms short, sharp, outwardly projecting angles on the nervules. 

 Beyond the outer line the subterminal space is darker gray, becoming 

 light as it approaches the subterminal line. On the costa, however, 

 this shade increases in depth as it proceeds, and contrasts strongly 

 for a short distance with the white line following the brown subterm- 

 inal. Terminal space dark gray, almost blackish. A fine white line 

 at the base of the fringe, connected with others crossing the gray 

 fringe at the base of the nervules. Posterior wings having a more or 

 less distinct, yellowish tinge, and with a blackish terminal border 

 and discal lunule. Nervules black. Fringe whitish. Beneath both 

 wings are yellowish, with a partly interrupted exterior line, and black 

 discal dots. The costa? of both are purplish gray, and the wings are 

 more or less covered with blackish atoms.
