D. abrasa H.-Schdff. (185 a). Reddish yellow; antennae black, moderately pectinated, with tufts of 
scales apically; prothorax pale yellow, each side with a brown spot connecting the streak of the two forewings. 
Tarsi apically black. Forelegs partly black. Forewing reddish, pale yellow along the costa, with a small oblique 
discal spot; a median stripe and the distal margin brown. Colombia, Venezuela, Guiana. 
B. (?) laxta Drc. Forewing brownish grey, undulate brown lines from the costal margin to the anal 
margin. Hindwing dark grey, palest at the base. Wings beneath grey without any marking. Antennae and 
legs pale brown. Head, thorax and abdomen pale grey. Closely allied to ampela. Ecuador, Sarayacu. 
D. (?) alba Drc. Forewing of $ white, slightly transparent, pale brown along the inner margin. Head, 
thorax and abdomen brownish white, antennae pale brownish yellow, legs pale brown. The $ is considerably 
larger than the S'; forewing somewhat browner at the costal margin, but without the intense colouring at the 
inner margin. £ 13 mm, $-24 mm. Mexico, Presidio (Forrer); Guatemala, Volcano of Atitlan, 2300—3500 ft. 
D. (?) ampela Drc. (185a). Forewing white, the costal half slightly hyaline; inner margin and anal 
angle shaded with pale brown; a brown streak right across the anal angle. Hindwing purely white, slightly 
shaded with brown at the distal margin near the anal angle. Head, thorax and abdomen pale yellowish brown. 
Head and antennae somewhat darker brown. Bolivia. 
D„ (?) semirufa Drc. Head, collar, tegulae, thorax and abdomen yellowy antennae and legs black. 
Forewing red, costal margin and distal margin greenish yellow; hindwing yellow, margined with black from 
the apex to the anal angle; fringe yellow. Both wings beneath yellow, broadly margined with black. 38 mm. 
Colombia. Rio San Juan, Chaco (G. M. Palmer). 
D. (?) variegata Jones. S' palpi ochreous; head and antennae grey; legs oehreous. tarsi white, their 
last joints black; tegulae and patagia brown. Abdomen above golden yellow, pale ochreous beneath. Forewing 
yellow, distal half suffused with brown, very dark at the margin, and a curved undulate antemedian line. A 
brown spot in the cell. An orange, black-edged line is followed on the discocellular veins by a- yellow area. A 
large macula and a small one at the apex. Hindwing orange. Marginal area and distal margin broadly black. 
Forewing beneath yellow, distal half with 2 yellow spots at the apex; hindwing yellow, the marginal area broadly 
yellow. Expanse: 23 mm. Castro, Parana, Brazil. 
D. nigrella Dgn. Wings rounded as in abrasa. Forewing divided by two folds, the first before vein 6, 
the second on vein 7; all the veins originate from the cell separately; 4 and 5 nearing each other, 6—9 at equal 
distances from each other, 10 somewhat more remote. 11 from the cell. Hindwing: vein 8 free. Frons greyish, 
head and thorax blackish. Abdomen above blackish, the segments finely bordered with white; ventrum and 
coxae white. All the wings blackish; hindwing beneath growing paler on half of the abdominalis. Fringe of 
the same colour; somewhat whitish at the anal angle. I S\ French Guiana. 
2. Genus: Zadaleera Dyar. 
Structures as in Dalcera, but vein 11 arises with veins 9 and 10 on a short stalk, whilst 9 and 10 are 
long-stalked. Type of the genus: Zad. fumata Sells. 
Z. fumata Schs. Palpi and head orange. Collar whitish; thorax and abdomen orange. Forewing above 
light pinkish yellow, palest along the costa; an oblique black stripe at the end of the cell, below this stripe and 
from near the base of the subcostal vein almost to the middle of the distal margin there is an intense smoky 
black shadow from which a similar, though smaller shadow extends to the inner margin. Hindwing light yellow, 
orange along the inner margin; wings beneath orange, the forewing with a black base of the costa and a black 
macula at the end of the cell. 31 mm. Castro, Parana. 
Z. arhathdota Dyar. Forewing “greasy” yellow, the costal margin and fringe without any light pink 
colouring* Hindwing orange. Expanse: 50 mm. Colouring otherwise very similar to that of Dalcera abrasa , 
but the wings are less oval, without a produced apex, but of a more normal shape, and the colouring is less 
intense. 1 $ Rio de Janeiro. Brazil. 
Z. munica Dyar. Similar to fumata , but vein 6 much nearer to the lower cell-angle. Discal transverse 
streak long and narrow. A median grey shadow to the margin is broadly expanded. Expanse: 31 mm. San 
Bernardino, Paraguay (K. Fiebrig). 
Z. dierrhoea Dyar. Similar to arhathdota. but smaller. Vein 6 arises above the end of the discal vein 
instead of forming the continuation of it. Expanse: 35 mm. San Bernardino. Paraguay.
