P. olivacea Msclilr. has olive yellow forewings strewn with brown, shaded somewhat darker at the base 
and in the marginal area behind the postmedian line; both the transverse lines are indistinctly double, bordered 
somewhat lighter and dentate, the posterior one followed by 3 dark internerval spots; before the apex at the 
costal margin there is a dark brown triangular spot below which a light oblique line parts the apex; a few small 
olive greenish spots in the cell, a light lunar streak at the cell-end. Hindwing brownish-grey. Surinam. 
P. stragula Mschlr. (146 h) is somewhat similar to olivacea, the forewing is yellowish olive grey, somewhat 
more yellow in the median area, edged by two indistinct dentate darker single transverse lines; a large guttiform 
olive brown preapical spot; the apex itself is not parted by light as in olivacea ; small dark internerval spots 
before the margin, double dots at the base of the fringe between the veins. Hindwing brownish-grey. The 
abdomen exhibits a pear-shaped dark velvety brown spot on the last segments. The species was described from 
Surinam, but it occurs also in Colombia and Bolivia. 
P. albiluna sp. n. (146 h) agrees well with the diagnose of the genus, but it looks very different. The 
whitish ground of the fore wing is densely strewn with brownish, more densely in the basal third of the inner 
margin, with finely black-striped veins; a broad black stripe extends from the basal fifth of the costal margin 
along the lower half of the cell, then behind it between the veins 4 and 5 almost to the margin, from where 
it bends round as a notched submarginal line into the costal margin before the apex, a long black wedge is 
detached from it between 5 and 6 towards the upper cell-end; the black longitudinal stripe is interrupted at 
the lower cell-end by a thick chalky white crescent; somewhat more whitish colour distally notched occurs 
subterminally in the lower half of the margin. Hindwing short and round, semi-diaphanous white, veins and 
marginal line narrowly brown, costal and inner margins brownish. Described according to a q from Joinville 
(Brazil); type in the Senckenberg Museum. 
43. Genus: Hamirionta Dogn. 
The ciliated antenna shows a knotted thickening right behind the base with a hook-shaped appendage; 
the second very hairy joint of the palpus is upcurved on the vertex, the terminal joint is slender and bent 
backwards like a hook; the legs are uncommonly hairy. Eorewing: vein 5 from the centre of the cross-vein, 
6 arises from the areole, 7 a little below its apex, the two next veins stalked from its centre, and 10 shortly 
before. All the cellular veins of the hindwing are not stalked. Only 1 species: 
H.unca Dogn. (= muscosa Rothsch.) (146 h) is somewhat like Drugera morona ; forewing blackish 
strewn with greenish, with double transverse lines partly bordered or filled with white, a faded black median 
line between them, the posterior line broken up into small internerval lunae. Hindwing blackish with lighter 
fringe. Guiana. 
44. Genus: Eusteiiia Schs. 
Here four fifths of the antennae are pectinated, the short palpi straightly porrect, the legs moderately 
hairy. The forewing shows the same neuration as Pseudodryas except that vein 6 arises directly from the upper 
cell-angle, while the costal vein of the hindwing branches off close at the upper cell-angle. Only a small number 
of rather similar species. 
Type of genus: E. dara Drc. 
E. dara Drc. (146 i) has plain mouse-coloured, scantily scaled forewings with a slight silky gloss, without 
any marking; anterior part of the body yellowish-brown, abdomen darker brown with yellowish bands. 
Described from Mexico. 
E. sericea Schs. Body red-brown, with yellow transverse bands on the abdomen. Forewing silky grey, 
with somewhat darker veins, a feeble darker grey postmedian shadow which is slightly bent below the costal 
margin. Hindwing with brownish hair at the inner margin. Expanse of wings: 57 mm. Costa Rica. 
E. opaca Schs. (146 i) is very similar to sericea, but darker purple brown, beside the abdominal segments 
also the collar is covered with yellowish ochreous hair. The forewing shows a strongly curved postmedian 
transverse line which is shaded with darker outside like a spot behind the cell, and bordered with lighter inwards; 
it is interrupted inwards on vein 4 and extends submedianly very obliquely to the inner margin. Brazil. 
E. rapana Jones. The light brown forewing is greyer at the costal margin and in the anal half, otherwise 
strewn with dark brown; a darker undulated shadow extends through the centre, with an undulated transverse 
line behind it, which surrounds the cell, and a brown subterminal line; a white band proceeding from the base 
of the inner margin extends to the upper edge of the cell, from there to the upper cell-angle where it bends 
downwards on the cross-vein, forming a small discal luna; behind this band lies a triangular darker area extending 
to the anal angle; a white spot is shortly before the centre of the inner margin. Expanse of wings: 58 mm. 
Brazil (Parana).
