DYMBA; SIGELA. By Dr. M. Draudt. 
acidalica. A. acidalica Hmps. (50 a). Forewing light reddish-brown with black costal-marginal dots, with a darker 
oblique median line, a whitish postmedian line inside shaded with red-brown, and feeble red-brown subterminal 
shadows. The similarly coloured hindwing exhibits, like the forewing, a black central dot and the same lines 
and shadowy markings. Known from Jamaica. 
clam. A. elam Schs. (50 a), originally described as Acidalioides and somewhat similar to truncata, belongs to 
this genus. Forewing slightly cut out below the apex, grey with a white costal margin spotted dark brown, 
with whitish faded antemedian and postmedian transverse bands, the anterior one inside bordered with darker 
grey, and with a white undulate line inside shaded with darker grey; distal margin tinted reddish-yellow, with 
a black streak above the anal angle. Hindwing light reddish-brown, at the distal margin darker, in the middle and 
at the anal margin befoi’e the whitish undulate line strewn with blackish-brown. Costa-Rica. 
bctie. A. betie Dyar (50 a). Forewing with a rounded margin which projects somewhat pointedly at the apex 
and in the centre, white, scantily strewn with brown, with a dark brown discoidal dot and a shortened band 
before the anal angle. The white hindwing exhibits a produced apex and a median band and two subterminal 
ones formed of dark brown scales. Panama. 
Wilhclmina. A. wilhelmina Dyar (50 a) exhibits on the distal margins of both wings two concave indentations each; 
forewing white with 3 very feeble fine transverse lines proceeding from black costal-marginal clots, and a broad 
blackish, twice interrupted subterminal shadow and a black discoidal dot; a black marginal line only occurs 
in the indentations. Hindwing the same, though much more feebly marked. Mexico (Tabasco). 
7. Genus: Dyiaiba Dyar. 
Distinguished from the preceding genus by somewhat longer palpi the middle joint of which is towards 
the end thick and loosely scaled; no tufts on the scaled body. On the forewing the two lower radial branches 
are stalked, the upper branch rises from below the upper cell-angle; the 4 lower subcostal branches are stalked, 
the uppermost being separate. Only 1 species: 
coryphata. D. coryphata Dyar (50 a). Anterior body lilac grey, abdomen white with small black dorsal spots. The 
long pointed forewing is white, the basal area dark purple with deep brown subbasal and anterior transverse 
bands; central area strewn with brown and black excepting a white cellular spot with an oblique black line 
behind it; posterior transverse line indicated by a black costal-marginal band; apex broad white. On the white 
hindwing black irroration forms 4 more or less interrupted transverse lines. Panama. 
8. Genus: Sigela Hulst. 
This genus being also known as Pseudocraspedia Hmps. has more slender and longer palpi which are 
more scantily scaled, the abdomen exhibits small feeble tufts. On the long narrow forewing the upper median 
branch is stalked with the lower radial branch, the uppermost rising from the upper cell-angle; subcostal 
branches as in Dymba\ on the hindwing the middle radial is feeble. 
leucozona. S. leucozona Hmps. (50 a). Forewing blackish-brown, mixed with white, especially at the costal margin, 
apex and distal margin, the costal margin being streaked black and white in the marginal half, the white 
transverse lines are very oblique, the posterior line is inside shaded with black, between both there is an oblique 
blackish median line; a whitish subterminal line is only visible in the lower half. Hindwing very similar with 
a broad white median band. Panama to Colombia. 
sodis. S. sodis Dyar (50 a). Forewing greyish-white with small black costal-marginal spots, with a curved, 
somewhat lighter whitish postmedian band and, before the anal angle, with a brown shortened oblique band. 
Hindwing greyish-white, the base and 2 oblique bands behind it grey; marginal area broad grey with a white 
subterminal line forming two bows. Panama. 
holopolia. S. holopolia Dyar (50 a). Dark grey with a straight oblique line in the middle and a finer one behind 
it, which are somewhat divergent towards the costal margin; a subterminal shadow slightly widens analwards. 
Hindwing with a straight brown median line, behind it a fine undulating line behind which a straight line and 
a broad dark marginal line follow. Panama. 
mathetes. S. mathetes Dyar (50 a). Forewing light grey with a narrow straight oblique line in the centre and a 
dark brown irregular macular band near the margin. Hindwing the same, but instead of the macular band 
there are 3 dark lines close together, the interior one being narrow, the two exterior ones broad. Panama. 
eubleptica. S. eubleptica Schs. (50 a) is allied to leucozona. Forewing blackish grey with a yellowish costal margin 
and apex, and a very oblique black line from the base of the inner margin towards the upper third of the distal
