Ps. ochriplaga Dgn. (170 a) differs a little in the scheme of markings. Wings greyish brown, the lines 
blackish brown. Forewing with 2 distinct thick lines. Interior line very obliquely outward, the exterior one 
less oblique, from 2 / 3 costal margin to 4 / 5 inner margin. The whole wing striated dark. Near the margin a kind 
of submarginal line is formed by denser streaks. Hindwing striated only at the distal margin. Interior line fine, 
almost parallel with the interior margin, indistinct, dentate, connected with the exterior line at vein 4, the 
exterior line double, almost parallel with the interior one. Ochreous at the little tail as far as the exterior 
line, 3 bluish black marginal spots between veins 3 and 4. 33—36 mm. Colombia, Costa Rica (Chiriqui). 
The following species exhibit the distal margin of the forewing 
angled at vein 4 , slightly cut out above it. 
Ps. subangulata Warr. (170 a). Similar to placidaria (170 b), but separated by the distal margin. Wings 
lilac grey, densely striated dark brown, especially at the distal margin of the forewing. Interior line from % 
costal margin to x / 3 inner margin, with a black spot at the costal margin, then very finely continued. Exterior 
line very oblique from % costal margin, slightly undulated as far as vein 4, then strongly inward and ver¬ 
tically to 2 3 inner margin. The usual submarginal spot is present. Hindwing with a very dentate exterior line, 
dark brown and double from the costal margin to the angle, then fine and indistinct. A broad brown shadow 
at the margin from the apex to the dental projection, and a large spot in the tail. 30 mm. St. Vincent. 
Ps. amplata Warr. (170 b). The indentation at the margin is stronger in the $ than in the + Similar 
to subangulata (170 a), but larger, the interior line is only discernible at the costal margin. The exterior line 
shows another slight outward bend in the submedian fold. Hindwing with 3 black lunae behind the exterior 
line near the inner margin; these lunae are more distinct in the + 34 mm. Paraguay, Rio Grande do Sul. 
Very dark, indistinctly marked specimens from the Chiriqui in Costa Rica. 
6. Genus: Tricolpia Warr. 
Forewing broad, costal margin bent, apex pointed, distal margin with an angle at vein 4, cut out above 
it. Vein 3 a little before the lower cell-angle, 5 near the upper angle, 6 + 7 and 8 —(— 9 -j— 10 stalked. Hindwing 
pointedly projecting at vein 4, fine dents at veins 2 and 3, the margin otherwise straight. Veins- 3, 4 and 6 , 
7 from the cell-angles. Antennae of $ only laminated, not pectinated. Type: acutaria Wkr. 
T. acutaria Wkr. ( = biangulata Fldr.) (170 b). Wings yellowish white. Interior line of forewing dark, 
indistinct, very obliquely outward as far as the middle of the cell, then vertical to y 3 inner margin. Exterior 
line obliquely outward as far as vein 5, somewhat inward at vein 4, then slightly outward to 4 / 5 inner margin. 
A violettish brown spot behind it below vein 4. Hindwing with double interior and exterior lines, distinct, 
dark, filled with white, very far extra-angular in the middle. Narrowly brownish at the margin. $ darker brown. 
20 mm. Venezuela, Guiana, Amazonas. 
T. flava sp. n. (170 b). $ distal margin of forewing uniformly bent. Ground-colour reddish yellow, 
finely striated brown. Exterior line fine, brown, obliquely outward from % costal margin to vein 4, slightly 
extra-angular at vein 6 , slightly bent inward below vein 4. Hindwing whitish at the costal margin in the in¬ 
terior part. Exterior line fine, rusty brown, straight, from 2 / 3 costal margin to vein 4, where it is angled, and 
straight to the inner margin shortly before the anal angle. $ 20 mm. Goyaz, type in the Senckenberg Museum, 
taken by Dr. Seitz in Viannopolis (Tavarez) in February 1930. 
7. Genus: Skupllioil gen. nov. 
Palpi short, antennae of $ thick. Costal margin of forewing bent before the apex. Apex pointed, distal 
margin projecting at veins 3 to 4, slightly concave above it. Veins 3 and 4 from the same base, 2 far back, 5 
close below the upper cell-angle, 6 + 7 stalked and 8 + 9 + 10 stalked. Hindwing with a point at vein 7, 
with a broader lobe at vein 3 to 4 than on the forewing, an angle at vein 2, slightly excavated before and 
behind it. Veins 3 and 4 from the same base, 5 a little above the middle of the cross-vein, 6 + 7 on a short 
stalk. Type: lilacina sp. n. 
S. lilacina sp. n. (170 b). Slightly similar to Trot, metachromata (170 c). Lilac grey. Interior line of 
forewing outward from + costal margin, angled at the anterior and posterior cell-margins, vertical between, 
dark, then white, bent inward almost as far as the base at the inner margin. Exterior line white, edged with 
brown inside, outward as far as the bifurcation of veins 6+7, then to vein 4, along which it extends some¬ 
what inward, then to 4 / 5 inner margin, concave between. A rusty brown blotch between veins 4 and 6 before 
the excision, somewhat rusty brown also at the anal angle. Hindwing with both lines white, projecting very 
pointedly at vein 4, the interior one somewhat indistinct. The exterior one pale brown inside in the anterior 
part, edged with blackish in the lower part. Broadly bluish white behind it from vein 4 to the inner margin. 
The veins on both wings lighter. 18—19 mm. Venezuela, Brazil. Type in the Berlin Museum. 
S. plagifaseiata sp.n. (172 a). Reddish brown. Subcostal vein of forewing lighter brown. The two 
lines proceed from two large triangular spots, close together. Interior line of black spots straightly inward to 
y 3 inner margin. The exterior row slightly angled outward at veins and below vein 4, then vertical, to % inner
