PSEUDIDONAUTON — PRAESUSICA. By Dr. M. Hering. 
63. Genus: Pseuclidoiiautoii gen. nov. 
it corresponds with the preceding genus, but 8 of hindwing deviates soon after the origin from the 
anterior edge of the cell, while 3 and 4 arise from the same point. 
Type of genus: P. admirabile Her. 
P. admirabile sp. n. (88 d). Thorax and basal third of forewing chestnut-brown, the latter distally admirabile. 
defined by a convex silvery line, pale brownish behind it, unnoticeably lighter in the apical area, the apex itself 
with a narrow chestnut-brown crescent. Hindwing, abdomen, and under surface yellowish-grey. Expanse of 
wings: 14 mm. Malay Peninsula. $ type from Padang-Rengas (Tring Museum). It may be that ldonauton 
nigribasis (p. 702) showing a smaller basal area without the silvery line and apical sj}ot also belongs to this genus. 
64. Genus: Hydroclstdft Meyr. ( Lasiolimacos B.-Bak.) 
Antennae of $ long bipectinated basally, palpi porrect, posterior tibia with 2 pair of spurs. Forewing: 
7—10 stalked, 7 arises after 10, 11 straight. Hindwing: 6 + 7 stalked, 8 connected with the anterior edge of 
the cell near the base by a cross-vein, with numerous small cross-veins extending towards the lobately projecting 
costal margin. Near to the genus Susica (p. 706) in structure and habitus, easily separable by the very convex 
costal margin of the hindwing. 
H. antigona Meyr. (= pratti B.-Bak.) (88 d). Fore wing pale yellowish, with a black central dot, behind antigona. 
which there is a brown oblique line from % of the inner margin into a brown spot at the costal margin before 
the apex, from which a second subterminal line extends to the margin above the tornus, being somewhat broken 
above vein 4 and sometimes connected there with the oblique line by a dark longitudinal ray. A broad dark 
costal-marginal spot near the base; forewing of the fresh insect coarsely dusted with black. The oblique line is 
always more or less indistinct in some places, or more thickened at the inner margin, costal margin or cell. 
Hindwing from pale yellow to brownish, all the fringes (of fresh specimens) with deep black spots. Expanse of 
wings: 32—42 mm. New Guinea and adjacent islands, November till March. 
H. kenricki B.-Bak. (88 e) is very similar to antigona, forewing often more reddish, well discernible by kenricJci. 
a narrow transverse line at the base of the fore wing; the oblique line is always uniformly fine, only thickened 
at the inner margin, the dark costal-marginal spot before the apex rather inconspicuous. Expanse of wings: 
25—35 mm. New Guinea, Australia. 
H. ferruginea B.-Bak. (= Squamosa ferruginea B.-Bak.) was evidently described by the same name 
in 2 genera. Gomana euryparoa Trnr. may also belong to this place. 
H. nigriplaga sp. n. (88 e). Thorax and head above dark grey, without a dark median line, abdomen nigriplaga. 
brownish-grey. Fore wing pale yellowish, scantily dusted with dark, resembling antigona ; but it lacks the two 
transverse stripes instead of which the space between them is filled with jet-black, crossed by the ground¬ 
colour above veins 4 and 7, so that 3 spots are produced decreasing greatly in size towards the costal margin. 
Central dot black; subbasal spot black, extended here to the base. Hindwing paler yellow. All the fringes with 
a row of black dots. Expanse of wings: 30 mm. New Britain, March and April, $ type from Talesca in the 
Tring Museum. 
65. Genus: ffypseloloplia Trnr. 
Palpi moderately long, rising. Antenna of bipectinate in the basal half. Thorax with a large anterior 
and smaller posterior tuft. Posterior tibia with 2 pair of spurs. Forewing: 7—9 stalked, 10 from the same place 
or stalked. Hindwing: cell short, % of the length of the wing, 6 + 7 stalked, 8 connected near the base with the 
anterior edge of the cell by a cross-vein. 
H. hypodrosa Trnr. Head white, thorax whitish, dusted with brown, posterior tuft brown, abdomen hypodrosa. 
brown. Fore wing brown, base and centre of disc broadly dusted with whitish, with an irregular dark brown 
cross-vein spot. A line of whitish dusting at the margin is interrupted by the veins. Hindwing yellowish-white, 
brownish towards the margin. Expanse of wings: 28 mm. North Australia, in February. 
66. Genus: I*raesusica gen. nov. 
Similar to Susica in structure, but the posterior angle of the cell in the hindwing projects little beyond 
the anterior angle towards the margin, the palpi do not project beyond the frontal tuft or but little, the antennae 
of the are pectinated moderately long and the pectinations gradually pass over into serrate dents from the 
middle of the antenna. Forewing: vein 10 is separated from the stalked 7—9 and arises freely from the cell as 
in Susica. Hindwing: 8 connected with the anterior edge of the cell by a cross-vein. 
Type of genus: P. placerodes Trnr.
