dark lino and a paler subterininal line vaguely visible in most specimens; 

 obsolete in some, and (juite distinct in others. The markings are most 

 evident in the paler specimens, and disappear entirely in the dark forms. 

 J)Cneath more grayish, with coarse brown i)owderings. Primaries with 

 an exterior dark line and a partial subterminal line which is best marked 

 on the costa; secondaries with the maculation of the ui)per side more 

 distinctly repeated.

Habitat. — Southern States; Morida in April; Texas in May and 

 August. 



Thes])ecies is a marked one, and otlers little variation except in depth 

 of ground color. It seems to be not uncommon in its range, specimens 

 occurring in almcjst all collections.

Head rather small and not prominent; eyea naked, large, not at all 

 protuberant. Ocelli distinct, situated close to the compound eye and 

 somewhat removed from the base of the antenna*, without an evident 

 pointed frontal tuft. Paljii long, compressed, oblique, and clothed with 

 upright scales m the female, recurved and with the scales directed for- 

 ward in the male, the clothing not excessively long in either case. 

 Tongue moderate in length and strength. Antenme situated on the 

 vertex, well forward, about two-thirds the length of the forewing; 

 simple in the female, with lateral bristles in the male, the joints fur- 

 nished inferiorly with tubercles from which arise tufts of long hair. 

 Body moderate or slight, abdomen cylindrical, reaching to or a little 

 exceeding the anal angle of secondaries. Legs moderate in length, 

 quite stout; tibiae with the usual spurs. 



In the male the anterior tibia is very much abbreviated, anteriorly 

 prolonged into a process which is (juite prominent and densely scaled, 

 covering also a mass of specialized scales. The basal joint of the tar- 

 sus is very long, exceeding the tij) of the tibial process, and near its 

 tip, extending ui)ward, is a peculiar hulle shaped ajtpendage, the handle 

 quite slender and flattened, the bowl hemispherical nearly and fringed 

 at the edges; externally it is covered with ]»n]»illate ])rocesses, while 

 inwardly it is clothed with long hair. Tliis same structure is also 

 present in Palthis, but seems to be al)sent in all other genera. The 

 wings are broad, rather frail in appeaiance, trigonate, moderately long, 

 primaries with the costa arched, the apex sharply rectangular, middle 

 of outer margin distinctly tliough not ])rominently angulated, a very 

 little excavated from that point to the costa and toward the hind angle 

 quite oblique. Secondaries rounded, a very little retracted oi)posite
