D. geon 3Iab. is allied to the two preceding, but well discernible bj' the hindwing beneath. Above 

 chocolate with similar spots, but the cellular spot is triangular, united with the middle di.scal spot. Hindwing 

 blackish-brown with a large, oval spot being produced somewhat proximally, fringes orange. Forewing beneath 

 yellow, tinted blackish between the discal and apical spots as far as the proximal angle : hindwing yelloM . towards 

 the margin tinted reddish, the discal spot semicircularly surrounded by B ferruginous sjiots, that at the proximal 

 margin being the largest. Ecuador (Loja). 



D. oxaites Heiv. (= syrisca Mob.) (179e, f) is somewhat smaller, the cell-spot is flown together with 

 the discal spot below it to a large triangular spot, distally there is another one, the 3rd is absent; the black 

 fringes are distally whitish. On the brown under surface of the forewing the spots are larger, the discal spots 

 form a band; hindwing dark reddish -bro-\\n, beside the large white discal spot there is an oblong one at the 

 base of the costal margin, a large one at the costal angle, at the base of the cell a small one which may also 

 be absent, and along the distal margin fi whitish spots of which that at the anal angle is the largest. Proxi- 

 mal margin bluish-grey. Bolivia. 



D. octomaculata G. ct' S. (179 e) also belongs into this group. Above similar to eryonas, somewhat 

 larger and with broader wings, with larger yello^^•ish-white spots. Beneath the hind\^•ing is without the costal- 

 marginal and costal-angular spots, beside the discal spot there are only 2 at the anal angle. From Costa Rica. 



D. eryonas Hew. (= dolabella Plotz, troetschi Stgr., heteropterus Plotz, fimbriola Stgr. i. 1.) (179 e) 

 is very much like oxaites, but it only has 2 subapical dots, the 2 discal spots are better separated, on the hindwing 

 the discal spot is more yellow, more oblong, extending farther to the proximal and costal margins. Beneath 

 on the hindwing the whitish spots are much more extensive. From Panama through Colombia to Biazil. 



0. hesperioides Fhlr. (179 f) is a much larger species, on the body and at the bases of the wings orange 

 or ochreous-yellow with similar spots on the forewings as in oxaites. The orange spot on the hindwings extends 

 to the base and to the proximal margin; fringes broadly orange. Beneath reddish-yellow, behind the middle 

 of the forewing black except the orange apex. Hindwing reddish-brown with torn yellow spots which are parth' 

 finely bordered with black. Colombia. 



D. polycrates Fldr. (179f) is of the same size, above without any reddish-yellow, body and bases of 

 wings somewhat haired olive-greenish. Spots of forewings white hyaline, the 2 middle ones not triangularly 

 flown together, but only separated by the median. Hindwing with a small, round, orange discal spot. Beneath 

 the hindwing is almost monotonously yellowish-brown with traces of a darker discal band. Colombia, Peru. 



D. superior sp. nov. (179 f) is still a little larger than polycrates. On the forewing the two discal spots 

 are broadly flown together, the lower one triangular, all slightly yellowish. On the hindwing there is beside 

 the bipartite orange postdiscal spot another basal one. Beneath the forewing shows a broad, yellow discal 

 band, the hindwing is dark red-brown with 3 slightly darker transverse bands which are, on both sides bordered 

 by undulate, fine, dark lines, one being situate basally, one in the middle with a long dentiform projection 

 below the costal margin, the third being antemarginal, the margin itself being narrowly darkened. Colombia: 

 Monte Tolima: (Fas.sl). 



D. caicus Hew. (179 f) looks above almost like a large eryonas, but above the middle of the proximal 

 margin of the forewing it has one more white discal spot ; the spot of the hindwing is white, large, rounded. 

 Beneath the hindwing is yellow, veined brown with the large, cpiadripartite discal spot and one more white 

 spot bordered with brown each at the costal angle and anal angle. Venezuela. 



D. inca sp. nov. (179 g) is very closely allied to caicus and above scarcely different, but the white spot 

 of the hindwing is not so round, but the cellular part more oblong; fringes of hindwings distinctlj' speckled 

 light and dark. Beneath all the yellow and brown tints are absent. Tlie apex of the forewing is lighter, grey, 

 the hindwing white, scantily dusted with grey, otherwise marked as caicus except the longer light cell-spot. 

 On the whole larger. From South Peru (Madre de Dios), taken by Fassl. 



D. ligilla Pldtz (179 g) is similar; above the 4 discal spots are fused into a single one, the spot of the 

 hindwing is decidedly yellow, also the fringes which are speckled a little darker. Beneath on the hindwing 

 the brown colour is more predominant ; at the base of the cell there is another long, light yellowish wedge-shaped 

 spot. Patria not stated. 



D. dimidiata Fldr. (179 g). Forewing spotted as in oxaites, hindwing with a large, white discal spot 

 extending to the costal margin, the proximal margin very much haired bluish-grey. Beneath unmistakable, 

 owing to the hindwing being white in the basal half and distally deep red-brown with blackish spots. Venezuela, 

 Colombia, Bolivia. In f. xantholeuca Plotz (179 g) from Venezuela the basal part of the hindwing beneath is 

 purely yellow. 



D. jelskyi Ersch. (179 h) is very different. Above almost as oxaites (179 e,f). Beneath the hindwing 

 is yellowish with dark brown veins except the transverse vein, so that in the middle a long stripe of the ground- 

 colour extends from the base to the margin. From Peru and Bolivia. 



D. lalage G. d; S. (179 h). Above blackish-brown with a large discal spot and a subapical spot of orange 

 colour, the spot of the hindwing large, orange, like the fringes. Beneath almost entirely light yellow, only the 

 forewing exhibits a blackish antemarginal band being forked towards the costal margin. From Mexico.
