into two scallops, the line ending at the costa just inside of the costo-apical spot. The line is 

 bordered externally with two lilac and a white and broad reddish Vandyke brown line; this 

 shade widens in the sinus; the apex is pale reddish; the edge of the wing fawn color. Costo- 

 apical spot black, irregularly oval, edged within with a blue semicircle and a few blue scales 

 on the costal side; the narrow blue- white submarginal line ending on the outer edge of the spot, 

 and besides two parallel blue-white streaks pass toward the apex. (This spot is larger, much 

 more perfect and specialized than in A. armida; the same in ?.) Discal spot ovo-lunate, dark 

 vandyke brown, paler within and with a clear central line or tissue; or the entire spot is dark, 

 opake. 



Hind wings vandyke brown, paler toward the base, no basal lines, a very faint discolora- 

 tion; outer line much as in the fore wings, curved outwards on the second median; a submar- 

 ginal series of seven larger unequal round nearly separate scallops, umber or pale vandyke 

 brown in color. Under side of wings of a uniform ash yellowish brown; all four discal spots 

 present and quite distinct; the submarginal line yellowish brown, but otherwise as above, as 

 are the costo-apical black ocellus, and the white and broad madder-red curved streak; hind 

 wings with the lines much as above. Legs brown, but all the tarsi yellowish brown. 



Expanse of the fore wings, S 103 mm.; 9 160 mm. 



Length of a fore wing, S 53 mm.; 9 88 mm. 



Breadth of a fore wing, S 29 mm.; 9 48 mm. 



Length of hind wing, $ 39 mm.; 9 64 mm. 



Breadth of hind wing, S 35 mm.; 9 50 mm. 

 Bonm'nghausen in Peters' Heteroceren-Raupen, etc., page 9, gives A. xanthopus as a syno- 

 nym of A. pandora, but until I have been able to make further examination and comparison 

 I should prefer to keep them distinct.

Imago. — 1 £19. Body and wings uniformly fawn brown, the S a little darker than 9 . 

 Head and palpi much darker than the rest of the body. Fore and hind wings not scalloped 

 on the edges. Fore wings with a broad diffuse basal line situated much nearer the discal streak 

 than the base of the wing; on the outer or hinder half of the wing it is curved outward. Discal 

 spot an indistinct broad line alike on both wings. Extradiscal line dark fawn, oblique, not 

 waved or scalloped, slightly excurved on inner edge of wing, ending on the costa on the outer 

 third of the wing. Halfway between the end of this line and the apex of the wing is a double 

 dark-brown irregular costal streak, from which passes a white line to the apex. A sinuous 

 white line edged more or less distinctly on each side curving outward in a large scallop toward 

 the apex and behind the double blackish spot; it makes two similar scallops in the middle of
