PLECTOTHRIPA; OCHTHOPHORA; ELESMA; CALATHUSA. By M. Gaede. 
33. Genus: Plectothripa Hmps. 
Palpi as in Gadirtha. Antennae of <$ shortly ciliated. Forewing oblong, rounded at the apex. Areole 
absent. Vein 7 on a short stalk with 8 + 9. Hindwing undulate at the margin, cut out at vein 1. Vein 5 bent 
upward, vein 6 arisis below the upper cell-angle, 8 is nearing vein 8 at the cell. Only 1 species known. 
excisa. P. excisa Hmps. Forewing greyish ochreous at the base, the rest red-brown. Interior line black, diffuse 
obliquely inward. A small black spot in the centre of the cell and black streaks at the cross-vein. An oblique 
dark line from the base of vein 2 to the inner margin. Exterior line dark brown, very oblique as far as behind 
the cell, then inward, undulate; a triangular greyish ochreous spot behind it at the costal margin. Submarginal 
line indistinct, dark, partly composed of spots. Hindwing greyish brown, reddish brown at the margin. The 
light spot at the base and behind the exterior line on the f'orewing may also be absent. + 34 mm. Singapore. 
34. Genus: Ochthophora Trnr. 
Palpi, legs and shape of wings similar to Gadirtha. Neuration of forewing normal; veins 4 + 5 of hincl- 
wing stalked, vein 8 fused far with the cell, the distal margin concave at vein 5. Only 1 species. 
sericina. A. sericina Trnr. Forewing silky greyish brown, greyer at the costal margin and at the base at the 
inner margin. Interior line fine, black, undulate, obliquely outward, traces of a few lines before it. Ring-macula 
and reniform macula indicated by brown scales edged with grey. Exterior line fine, notched, black, very oblique 
as far as vein 7, bent up to the upper cell-angle at vein 2, then along the inside of the reniform macula and 
outward to vein 2. Hindwing diaphanous white, narrowly brown at the margin. 38 mm. Queensland. 
35. Genus: Klesnia Wkr. 
Palpi shorter, hairy below. Frons with a long tuft. Antennae of <$ ciliated. Metathorax with a tuft. 
Forewing stretched, without an areole, vein 7 + 8 + 9 stalked. Veins 3 + 4 of hindwing stalked. Only 1 species 
with 3 names. 
subglauca. E. subglauca Wkr. (= philomela Lower, triorbis Trnr.). Forewing grey, slightly dusted with black. 
Interior line black, very oblique to the lower cell-angle, then incurved, and outward again above the inner 
margin. Ring-macula small, round, edged with black. Small black-edged lunae at the cell-angles, with brown 
scales inside. Exterior line fine, obliquely outward from below the costal margin to vein 5, then obliquely in¬ 
ward. notched. Submarginal line indicated by black notches on its inner side. Hindwing white, narrowly brown 
at the margin. 34 mm. N. S. Wales. 
36. Genus: (lalathusa Wkr. 
Palpi longer than in Elesma, thin, the third joint short. Antennae of $ with short tufts. Thorax tufted 
in front and behind. Forewing partly with a pointed apex. Neuration of forewing normal, of hindwing as in 
Elesma. Type: hasicunea Wkr. Nearly all the species originate from Queensland. They are most variable in 
their size and the marking of their wings. 
hypotherma. C. hypothernia Lower (38 b). Forewing greyish brown, darker at the inner margin as far as the middle. 
Interior line dark, almost vertical. Reniform macula elliptical, indistinctly edged with brown. Exterior line 
black, somewhat inward, almost straight, slightly excurved at vein 4. Submarginal line whitish, parallel. Hind¬ 
wing reddish yellow, broadly smoky brown at the margin. $ 26 mm. Queensland. 
ischnodes. C. ischnodes Trnr. (38 b). Forewing pale greyish brown, with black radial streaks in the basal and 
marginal areas. A pale bent interior line is traceable. The light exterior line edged dark, pointedly excurved 
at vein 3, vertically bent over in the submedian fold. Hindwing dark brown, paler at the base. 25—30 mm. 
Queensland, N. S. Wales. 
hemiscia. C. hemiscia Lower. Forewing whitish ash-grey, blackish in the anterior half, the two colours rather 
sharply separated. Interior line indiscernible like the ring-macula and reniform macula. Exterior line discernible 
from the lower cell-angle to the inner margin, with a round projection in the submedian fold, then oblique. 
Submarginal line dark, interrupted. Hindwing dark brown, lighter at the base. The species is said to be similar 
to ischnodes. $ 28 mm. Queensland. 
odogesima. C. octogesima Trnr. (38 b) resembles ischnodes in the shape of the exterior line. Forewing darker greyish 
brown. Interior line black, slightly undulate, vertical. Ring-macula with a double dark border, double below, so
