DALLA. By Dr. M. Deaudt. 921 



D. cypselus Fhlr. (179 c,d) is above blackish-brown with -t yellowisli-wliite fliscal spots on the fore- cy/w^K.s. 

 wing and 3 small subapical dots; of the former a small one is in the cell-end, 2 larger, separated ones below 

 it and the 4th outside of them somewhat below the apical dots. Hindwing with an oval, somewhat reniform, 

 orange discal spot, and towards the anal angle with orange fringes. Beneath more chestnut-coloured, the sub- 

 median spots of the forewing broadly united, towards the proximal margin of a deeper yellow; at the anal angle 

 of the hindwing only a minute yellow diffuse spot. Colombia. 



D. frater Mab. (= mesoxant ha P/d/2) (179 d) is verj' similar, mostly larger, the uppermost submedian jrtilfr. 

 spot broadly flown together with the cellular spot which is larger here; beneath at the anal angle of the hind- 

 wing a larger orange spot. Venezuela, ('olombia. 



D. virius Mnb. is larger than r j/p.selu.s (179 c, d), the spots on the forewing are of a deeper yellow, rh-hts. 

 the cellular spot is larger, touching the quadrangular spot below it. The orange spot of the hindwing is somewhat 

 indented at the proximal margin, the fringes are dark brown. Beneath the discal spots of the forewing form 

 an angled band as far as the costal margin. Zamora (Ecuador). 



D. gelus Mab. (vicina Mab. i. 1.) (179 d) is somewhat smaller than cyp.selus and virius. The spots t/cln.s. 

 on the forewing are the same, but somewhat larger and whiter, the two lower discal .spots almost touch each 

 other, the cellular spot is much smaller, placed near to the costal margin. The spot on the hindwing is likewise 

 lighter yellow, larger, rounder. The hindwing beneath exlribits at the costal margin 2 additional yellow spots 

 near the ba.se and behind the discal spot, a third is situate at the anal angle. From Bolivia. 



D. genes Mab. is larger than cypseltLS (179 c, d). Forewing jet-black with 3 subapical dots, the ynu's. 

 median one being minute, and 3 discal spots; that in the cell small, more remote from the others, light yellow; 

 the spot in the submedian space is entirely absent. The spot on the hindwing is large, oval, orange, on the veins 

 prolonged; fringes ferruginous. Beneath ferruginous, at the proximal margin of the forewing blackish. Hind- 

 wing reddish-brown, the discal spot blurred, only little lighter than the ground, bordered by 2 broken lines 

 of a dull brown; proximal margin blackish; at the ends of the veins one black dot each. Zamora (Ecuador). 



D. ticidas Mab. (179 d) is allied to the following species, but on the hindwing it resembles more cypselus ficMi-i. 

 by the oval sjDot. Discal spots in an oblique line, the two lower ones united, above them a streak in the cell, 

 which may also be absent. Hindwing with an orange discal spot. Forewing beneath at the apex and at the 

 costal margin red-brown, otherwise blackish; the discal spots are flown together into a very large one; hindwing 

 reddish-brown, the spot not distinctly defined, traversed by 2 or 3 red-brown lines. Bolivia. 



D. caenides He/c. (179 d) is very similar, the .spot of the hindwing longer, the fringes more red-brown, cucnidr.s. 

 beneath the discal spot of the hindwing is more sharply defined, not traversed by lines. Venezuela, Colombia. 



D. connexa sp. nov. (179 e) is allied to caenides; on the forewing the triangidar cell-spot forms a large roimcm. 

 quadrangle with the triangular spot below it, being diagonally parted by the median; at the distal upper angle 

 another small triangular spot is connected with the apex, subapically there are 3 minute spots, all of them orange 

 like the very large, oval, towards the base pointed spot on the hindwing ; fringes at the anal angle orange. Beneath 

 the apex of the forewing is reddish-grey, the discal spot very large, extended to the costal margin and proximal 

 margin. Hindwing reddish brownish-grey, at the proximal margin blackish, in the disc strewn with yello\;-. 

 Bogota. 



D. monospila Mnb. Forewing blackish-brown, 3 united subapical dots, the 3 orange discal spots com- monospila. 

 bined to one inclusive of a cellular streak, only separated by the veins, the distal one somewhat lighter, Hind- 

 wing black with a large ferruginous orange discal spot, equally broad and long, distally dentate. Fringes red- 

 brown. Beneath like the preceding, the discal spot clear, the proximal margin blackish. Bolivia, Colombia. 



D. cypria Mab. (179 d) is larger, forewing scarcely different ; the spot of the hindwing very long, removed ojpria. 

 near to the costal margin. Fringes of hindwings whitish and thereby easily discernible. Hindwing beneath 

 monotonously red-brown, discal spot little prominent, at the anal angle a small, yellow spot. Bolivia. 



D. cupavia Mab. is very closely allied to the following evages (scylln), ground-colour above blacker, cupai-ui. 

 spots whiter, the cell-spot absent; on the hindwing the discal spot is smaller, quite round, the fringes dark 

 ferruginous, at the proximal angle lighter; the hindwing beneath is more monotonous, Bolivia, 



D. evages Heic. (= scylla Mab.) (179 e) is above blackish-brown with 3 subapical dots, the middle evagcx. 

 one being the smallest; in the discal area 3 yellowish hyaline spots arranged in a line, above them in the cell 

 another small one. The spot of the hindwing is distally somewhat dentate, as in cupavia, too, towards the proxi- 

 mal margin extended into a point. Fringes of hindwings yellowish-white. Tlie forewing beneath is black, at 

 the apex and costal margin reddish; the lower 2 discal spots are broadly flown together white; hindwing reddish- 

 yellow, at the proximal margin light yellow, also at the co.stal and distal margins some dull, lighter patches. 

 Bolivia. 



D. charybdis sp. )i. (179e) looks above almost like scylla, the spots are whiter, the fringes of the charybdin. 

 hindwings dark. Beneath all the red-brown and yellow tints are absent, the ground-colour is also on the fore- 

 wings blackish-brown, the spots creamy-white, as above, but in addition there is one anal and one costal spot 

 each near the base on the hindwing. Bolivia.
