18 JOHN B. SMITH. 



Three specimens, representing both sexes, are at hand from Mr. 

 A. W. Hanham. I have no details regarding to capture of the 

 species and no date. The insects were assumed to be forms of 

 nictitans, and look like small, dark examples of that species. There 

 is really very little that can be added to what has been already said 

 concerning the male structural characters. The ciliations in the 

 antennae are very small and easily overlooked, except on close 

 examination.

 Ground color rusty red-brown, varying somewhat in shade, sometimes quite 

 smoky, and occasionally a specimen will become decidedly more yellowish or 

 eveu luteous in tint. The collar is a little paler interiorly, a brownish line mark- 

 ing the point where the difference in shade begins. The edges of the patagiw 

 are often blackish. The primaries have all the markings distinct, but hardly 

 contrasting, the lines being just a little darker than the ground color. The 

 ordinary spots are paler in color, and either more rusty or more yellowish if they 

 are not white filled. Basal line geminate, distinct, easily traceable to the sub- 

 median vein. T. a. line geminate, the space between the lines unusually wide. 

 As a whole the line is upright, but outcurved between the veins. T. p. line 

 geminate, the inner line irregular and crenulate, the outer often with a very 

 faint outcurve. The median shade line is rather neatly marked, only a little 

 broader than the other lines, a little more distinct, sharply angulated at the mid- 

 dle and a little incurved below. The s. t. line is dusky, tolerably well marked, 

 darker than the terminal space, and broken only at the apex, which is a little 

 paler than the rest of the wing. All the veins are dusky and the venation is 

 thus readily traceable. The orbicular is round or nearly so, moderate in size, 

 narrowly ringed, a trifle paler than the ground color, rarely white. Reniform 

 kidney shaped, moderate in size, sometimes a little constricted on the inner 

 edge, hut more usually irregular in shape. It may be a little paler than the 

 ground color, it may be white, or it may be white marked to a narrow brown 

 luuule which is near the inner border. The claviform is traceable in most speci- 

 mens and is sometimes often even distinct. Ordinarily it is small, extending 

 half way to the median shade, outlined as are the other spots and sometimes 

 paler in color; never white marked in any specimen that I have seen. Second- 

 aries smoky in some cases, almost blackish in others, again with a strong tendency 

 to yellow. Beneath more or less smoky, especially on the primaries; both wings 

 with an outer line and with a small discal spot. Expanse 1.15-1.40 in. ; 29 35 mm.
