GYMNOGELASTIS, n. g. 
Head smooth ; ocelli posterior; a strong ridge on each side of 
mouth below eyes, tongue reduced to two short projecting brushes 
of hairscales. Antennae nearly 1, scaled, thickened above on lower 
half with rough loosely projecting hairscales, scape rather elongate, 
swollen at apex, without pecten (in lilitha scales appressed, scape 
short). Labial and maxillary palpi absent. Legs long, posterior 
tibiae with long rough projecting hairs above, without middle- 
spurs, end-spurs very short. Eorewings 2 from §, 3 from towards 
angle, 4 from angle, 7 to costa, 8 absent (in one wing of one 
example 7 and 9 stalked), 11 from ft. Hindwings under 1, elon¬ 
gate-ovate, cilia 4; 2 from beyond middle, 3 remote, parallel, 
4 from angle, 5 separate, rather curved, or sometimes absent 
(lilitha), 6 and 7 parallel, 8 strong, near costa throughout, upper 
margin of cell absent, origin of 7 furnished by an oblique bar fiom 
middle of 8 to normal angle of cell. 
Type miranda Meyr., Exot. Micr. i, 142 (1913), referred erro¬ 
neously to Melodryas , the palpi of the single original type being- 
supposed broken, and the exceptional neuration of hindwings not 
correctly apprehended ; having now before me 4 examples of the 
genus, I am satisfied that the palpi are naturally absent as 
described. The extraordinary features of this genus make its true 
affinity puzzling. 
Gymnogelastis miranda Meyr. 
Two additional examples seen from Snow Mts., Dutch New 
Guinea; 24-427 mm., blackish scales of antennae extend to near 
apex, but are liable to denudation ; apical half of abdomen wholly 
blackish ; discal blotch of forewings extends obliquely to dorsum ; 
otherwise as in type. One example has 7 and 9 of one forewing 
stalked, an individual abnormality. Hindwings 5 always present. 
Gymnogelastis lilitha, n. sp. 
d . 20 mm. Head, thorax blackish. Antennse dark fuscous. 
Abdomen orange, anal tuft blackish. Eorewings elongate, costa 
gently arched, more strongly posteriorly-, apex obtuse, termen 
extremely obliquely rounded; blackish ; an elongate-oval orange 
patch extending in disc from ^ to §, resting on dorsum medially 
and reaching more than half across wing: cilia dark grey. Hind¬ 
wings 5 absent; orange ; a blackish apical blotch occupying about 
| of wing, and extended as a slender terminal streak to ^ ; cilia 
dark grey, on dorsum orange.
