CHIONAEMA. By JDr. M. Braudt. I 73 
chocolate transverse bands through the disc of the forewing. Biagi, Mambara River, British New-Guinea; 
5000 ft., taken in January. 
C. melanoplagia Hmps. is very peculiar for its thick scent-scale fur filling up the whole cell and costal 
margin, and very much curved venation. The olive-grey forewing has a black costal margin expanded in the 
middle into a triangular spot; behind the middle there is an oblique dentate line and behind it a large black 
spot at the proximal angle extending to the middle radial vein upward; at the margin a series of black spots. 
South West New Guinea (Kapaur). 
C. lignaria Rothsch. <$: head, antennae, thorax and abdomen greyish creamy buff strewn with small 
brown scales; forewing the same, partly clouded with small brown scales, for which reason it looks like wood. 
In the cell a small, stigma-like dot. Hindwing greyish-white, towards the apex washed over with a pinkish 
grey. Length of forewings: 12% mm. Biagi on the Mambara River in British New Guinea; at an altitude of 
5000 ft, 
C. basialba Rothsch. head, antennae and thorax buff, the posterior part of the thorax and the 
ends of the patagia white; the 3 basal abdominal rings grey, the rest buff, anal tuft white. Forewing buff, the 
basal quarter white with a brown basal spot. From the costa as far as almost through the cell extends a middle 
white spot, a white spot behind it at the costa, a large white apical spot and a white subterminal spot from the 
anal angle to vein 3; at the margin a series of small blackish-brown spots, connected by a fine line. Hindwing dark 
drab with a brown margin and grey fringes. Length of forewings: 15% mm. Biagi. Mambara River, Biitish 
New Guinea; taken by Meek in February at an altitude of 5000 ft. 
C. albomaculata B.-Bak. is one of the smallest species (expanse of wings: 20 mm) and has light 
brown forewings with 5 white spots, at the costal margin there is a small one above the middle of the cell, a larger 
one behind it and a large one at the apex; at the proximal margin there is a large spot below the middle of 
the cell, another one at the proximal angle. Head and fringes are white, the shoulder-covers with a large 
white spot. Body otherwise light brown. The cell of the forewing is entirely covered by a scent-scale spot of 
long, light brown hair. Hindwing diaphanous ochreous-brownish. In January and March on the Aroa River. 
C. fumea Hmps. is somewhat like charybdis Bak .: forewing of a sooty black with indistinct, oblique, 
darker ante- and postmedian transverse lines. Hindwing whitish with a blackish-brown discal spot and similarly 
tinted costal and distal margins. Proximal margin with long brownish hair. Anal tuft ochreous-yellow. From 
South West New Guinea (Kapaur). 
C. aroa B.-Bak. resembles fumea, but it is more blackish-grey, with a bronze lustre; the dark transverse 
bands broad and indistinct; the scent-scale spot like in melanoplagia Hamps. The dark grey hindwings are 
lighter towards the base. April, on the Aroa River. 
C. brunnea B.-Bak. Forewing brown, irregularly dusted grey; at the costal margin there is at the 
end of the scent-scale spot a light spot; below the cell and at the proximal margin light stripes; behind the 
middle there is an almost straight, dentate, light line; margin lighter. Hindwings brownish-grey, towards 
the base darker. February, Aroa River. 
C. punctifasciata Rothsch. head, antennae, thorax and abdomen slate-coloured grey. Forewing 
dirty brownish-grey, with 4 transverse bands of irregular darker spots bordered with a light grey; a dull ochreous 
spot in the cell. Hindwing brownish-drab. Length of forewings: 12 y 2 mm. New Guinea. 
C. plagosus Rothsch. antennae brown; head, thorax and abdomen light ash-grey, densely dusted 
with small sooty scales. Forewing: the basal third ash-grey, slightly dusted with small sooty scales, an almost 
extinct, sooty-brown, subbasal transverse band; the middle third of the wing sooty blackish-brown, scantily 
strewn with small whitish-grey scales and with a whitish stigma; the distal third light ash-grey, scantily strewn 
with small dark scales; a partly interrupted and obliterated dark antemarginal band and at the margin itself 
a series of small dark spots from the apex to vein 3. $ larger, the forewing dull buff, a large subbasal spot, 
a costocellular medium-sized spot and a small one at the proximal margin, as well as a broad marginal band 
are grey. Hindwings brownish-grey. Length of forewings: $ 13, $ 16 mm. Biagi on the Mambara River in 
British New Guinea; taken in March at an altitude of 5000 ft. 
C. nigrescens Rothsch. <$: antennae, head and thorax sooty blackish-grey; abdomen slate-coloured 
grey, anal tuft orange buff. Forewing sooty slate-coloured grey, marbled and spotted sooty black; a large, 
hairy scent-spot at the costa, being white when turned up. Hindwing with a wooden-grey basal half tinted 
yellowish and a sooty grey distal half, with a dark stigma. $ larger, the hindwing darker. Length of forewings: 
<3 19, 9 21 mm. Biagi on the Mambara River in British New Guinea; taken in March at an altitude of 5000 ft.
