DALLA. By Dr. M. Draudt. 923 



D. lethaea Schs. is above coloured and marked almost as lalage (179 h). Beneath the wings are leihaea. 

 deeper yellow, the cell of the forewing is black almost to the end, towards the base also below the cell; behind 

 it there is a broad black band not reaching the costal margin, being distally bent above the upper radial vein 

 and reaching the proximal angle beneath. The base of the proximal margin of the hindwing is scaled black. 

 Oosta Eica (Poas). 



D. lysis Schs. resembles somewhat the following /aitto (179 h); the forewing exhibits in the cell a yellow lysis. 

 triangular spot, below it behind the middle between the median veins a small spot and above it farther distally 

 yet a dot; distally below the costal margin a short oblique streak. The hindwing shows the large discal spot 

 of faula. Beneath the forewing is blackish-brown with a yellowish-brown costal margin, the distal margin 

 narrowly, the apex somewhat more broadly yellow, the yellow discal spot enlarged. Hindwing yellowish-white, 

 veined brown except the transverse vein and base of the middle radial vein remaining coloured like the ground. 

 Fringes brown. Costa Eica (Turrialba). 



D. faula G. d; S. (179 h) is very much like lalage, the spots somewhat lighter yellow, the discal spot faula. 

 somewhat differently shaped; the hindwing shows a long, narrow discal stripe which is parted at the lower 

 margin bj' the median. Beneath liliewise light yellow, the blackish marking somewhat more extended the 

 hindwing dusted with -brownish-grey except the cell. From Mexico. 



D. arpia Schs. (179 h) likewise belongs hereto, but the subapioal spots are entirely absent and the discal arjna. 

 spot extends from the subcostal vein to the submedian fold. Beneath almost as lalage, but the base of the fore- 

 wing is black and above the cell connected with the distal-marginal band not being forked. Hindwing quite light 

 yellow. Described from Eio de Janeiro, but it also occurs in Bolivia and is thus certainly widely distributed. 



D. pruna Plotz (179 h) from S. Domingo is perhaps only an insular form of the preceding with smaller pnnm. 

 spots above. Beneath the colour is more yellowish-grey; on the forewing only the apex is yellowish, the distal 

 margin is from the middle downwards dark brown like the proximal two thirds of the costal margin and the 

 whole basal half. 



D. seirocastnia sp. nov. (179 i) is above deep blackish-brown with an orange, bipartite discal spot and seirocastnia. 

 3 subapical dots of the forewing. Hindwing in the disc deep orange, broadly bordered with blackish-brown 

 with orange fringes. Beneath on the forewing the costal margin, apex and narrowly the distal margin are strewn 

 with red-brown. The hindwing is densely dusted with red-brown, but in the disc the yellow ground-colour 

 is scarcely visible; jDroximal margin black, strewn with yellow. From Colombia (Monte Tolima). 



D. privata sp. nov. ( 1 79 i) resembles the preceding on the forewing above, but the discal spots are smaller ; privala. 

 the hindwing is entirely blackish-brown without an orange discal area. Fringes red-brown, only at the anal 

 angle of the hindwing somewhat more orange, parted by a dark discal line. Beneath the hindwing is quite 

 red-brown, but verjr scantily strewn with yellow. Bolivia (Cuesta of Cillutincara). Type in the Coll. Fassl. 



D. agathocles Fldr. (179 i). Here begins a small group of species with several yellow spots of the agathodes. 

 hindwing. agathocles is above blackish, the small spots of the forewing are yellowish-white, insignificant. The 

 hindwing exliibits a large basal spot and behind it 3 distal-marginal spots, the two upper ones of which are 

 situate close together. Beneath the forewing is reddish-yellow in the basal and inner-marginal half, apically 

 blackish. The hindwing is reddish-grey with 2 slightly conspicuous yellowish transverse bands. Colombia. 



D. pulchra G. & S. (179 i) is similar, somewhat smaller; on the more chocolate ground the forewing pulchra. 

 exhibits one more light yellow spot in the submedian space, which is situate farther towards the base. The 

 hindwing only shows 3 deep orange spots, 1 towards the base, 2 distally ; the fringes of the hindwing are also 

 deep orange. From Costa Eica. 



D. saleca 3Iab. (179 i) is likewise very much like agathocles. The spots of the forewing are more reddish- saleca. 

 yellow, the cellular spot very much nearer to the spot below it. The fringes of the hindwing are dark red- 

 brown. Beneath the whole basal half; the costa and apex are blackish red-brown, only the discal macular band 

 is reddi.sh-yellow. The hindwings are likewise red-brown, the bands not very conspicuous. Colombia, Peru. 

 — From the Cue.sta of Cillutincara (Fassl) a form is before us: albescens sp. nov. (179 k) with larger, entirely albescens. 

 white spots. 



D. bubobon Dyar. Above bronze-black, spotted yellow: 1 obliquely quadrangular spot in the cell, hv.bobon. 

 2 faded ones below it, 2 more between and above the median veins, the lower one larger, below it another small, 

 dark yellow spot; hindwing with a yellow discal spot and 4 behind it, fringes speckled light. Beneath the spots 

 are larger, more numerous, particularly on the hindwing, where also 3 rou.nd spots are situate at the costal 

 margin. Expanse of wings: 36 mm. Mexico (Guerrero). 



D. grovius Mab. is larger than bubobon, the forewing with 3 subapical dots, a cellular spot and behind gmvius. 

 it and below it with 4, not 3 more spots. The spot of the hindwing is prolonged, of a brighter yellow than on 

 the forewing, from the costal margin a pointed tooth of the ground-colour penetrates into it; at the distal 

 margin there is only between the median veins a yellow spot. Fringes of hindwings orange. Beneath as saleca, 

 but on the red-brown hindwing there are 3 distinct light yellow bands, a broad basal band, another one bemg 

 connected with it extends to the costal angle, the third being extinct and situate near the fringes : on the ends 

 of the veins there are black dots. Ecuador (Loja). 



D. epiphaneus Fldr. (179 k) is still larger, at the bases of the wings dusted with ferruginous-bro^^^l, epiphaneuf!. 

 with lajge band-shaped, reddish-yellow spots as far as the proximal margin. The hindwing exhibits a basal
