russety scales. The secondaries on this side are profusely irrorated 

 with russety scales on the disk, forming faint nebulous cloudings. The 

 expanse of the wings is the same as in the male sex.

 Two males. 



TERACOLUS METAGONE, new species. 



Male.— Rend black; antenna' black, margined with whitish on the 

 under side; upper side of the thorax and abdomen black, the under side 

 white; legs white. Tiie primaries are pure white with the costa nar- 

 rowly edged with deep black from the base to the middle of the wing, 

 and then more broadly edged with black to the apex; the black border 

 extends around the outer margin to the inner angle, just before reach- 

 ing which it is greatly reduced in width, though not entirely vanishing. 

 Within this border the apical third of the wing is broadly marked from 

 just beyond the middle of the costa to the middle of vein 3 with bright 

 clear orange yellow. The black of tlie outer margin is produced 

 inwardly upon this orange tract on the ends of the nervules, and the 

 black of the outer margin runs inwardly quite deeply upon vein 3 

 and less deeply upon vein L>. The apical orange tract is not defined 

 inwardly by a transverse apical black bar. The inner margin is marked 

 by a broad, pale, blackish longitudinal band, which extends from the 

 base for about two-thirds of the length of the inner margin. The sec- 

 ondaries are white upon the upper side, with the base and the costal 

 margin marked with a broad longitudinal band of the same color as 

 that upon the inner edge of the primaries. The outer margin is marked 

 by a series of triangular black spots at the ends of the nervules. These 

 spots do not apparently tend to coalesce with each other. They are 

 smallest toward the anal angle. There is a faint giay shade running 

 from the inner margin above the anal angle outwardly to a i)oint a 

 little above the end of vein 3. The fringes of the secondaries are 

 white, those of the primaries black, except at the apex and at the outer 

 angle, where they are white, as on the secondaries. On the under side 

 both wings are white, both have a minute dot at the end of the cell. 

 The primaries are laved at the apex with pale lemon yellow, across the 

 middle of the yellow tract having a broad transverse shade of clear 

 orange. 



Female.— The orange red apical tract of the i»rimaries is more 

 restricted than in the male, and the outer dark marginal border is not 

 as dark as in that sex. Furthermore, the inner ei\<ie of the red tract 

 is crossed from the costa to vein 3 by a very irregular curved baud of 

 dark spots, narrowest between the upper median and the radial nerv- 

 ules. The base of the i)rimaries and the cell, as well as the portions 

 of the wings below the cell about the origin of the median nervules, 

 are broadly and evenly marked with i)ale blackish gray. This tract of
