NATADA; NATAROSA. By Dr. M. Bering. 
/ io 
16—24 mm. - - Larva pale green, with a purple lilac dorsal longitudinal band, on each side of which there are 
two rows of light purple spots and 4 rows of green appendages with purple black stings; on Cocos. Philippines. 
Th. plumbea sp. n. (89 f). Forewing dark brownish-red, the marginal third violettish-grey, parted 
by a narrow transverse line of the ground-colour, parallel to the margin, so that a lead-coloured grey transverse 
band .is produced at and before the margin. The dark central dot is indistinct. Hindwing dark grey. Expanse 
of wings: 20 mm. Borneo. S' type from Pontianak (Berlin State Museum). 
Th. arizana Wil. Antennae of S' serrate. Body dark brown. Forewing pale brown, somewhat whitish 
in the apical area. Basal area dark brown at the costal margin, a dark brown longitudinal streak through the 
centre of the wing almost to the margin. An undulated black antemedian line bordered with pale inside, from 
the centre obliquely to the inner margin, with a black dot outside, postmedian line black, broken up into dots, 
a pale line behind it to the margin above the tornus, the space between both brown, arched darker, a brown 
costal-marginal spot before the apex and a black spot at the beginning of the brown marginal line, fringe crossed 
by white. Hindwing blackish grey. $ similar, costal portion of discal area darker, enclosing a pale spot, veins 
2—4 black beyond the postmedian line, hindwing paler. Expanse of wings; 33—36 mm. Formosa, in March. 
It seems to belong to another genus. 
77. Genus: Natada Wkr. 
Very near to Thosea, S' antenna with pectinations gradually decreasing in length towards the apex: 
posterior tibia with 2 pair of spurs; 10 and 7 of forewing separated from the stalk 8 + 9, 11 arises opposite 2. 
N. rufescens Wkr. (89 e). Body dark brown, dorsum orange-brown; forewing brown, the straight and 
vertically cut off basal third dark brown, moreover a cross-vein dot and a submarginal line terminating above 
the tornus are dark. Hindwing somewhat lighter brown. Expanse of wings: 30 mm. India. 
N. fulvidorsia Hmps. (89 e). Head and thorax reddish-yellow; abdomen blackish-brown, pale yellow 
beneath. Forewing blackish-brown, partly feebly tinged with grey, some yellowish-red scales below the costal 
margin and below the cell-end. Hindwing blackish-brown. Expanse of wings: 26 mm. Ceylon. 
N. fulvimixta Hmps. (89 e). Body brown, slightly mixed with reddish-yellow, abdomen blackish- 
brown. Forewing dark brown, slightly dusted with grey and with a somewhat reddish-yellow tinge, with an 
oblique whitish transverse line bordered with black inside, from the apex to beyond the centre of the inner 
margin. Hindwing blackish-brown. Expanse of wings: 30 mm. Ceylon. 
N. griseimargo sp. n. (89 e). Dark brownish-grey, forewing with a dark submarginal line from 5 / 6 of the 
costal margin to the tornus, the marginal area behind it light grey. An indistinct blackish transverse streak 
at % on the inner margin, and a similar one across the cross-vein. Hindwing blackish-grey. Abdomen and under 
surface lighter brownish-grey. Expanse of wings: 23 mm. Burmah. S' type from Maymvo (Burmah) in the 
British Museum. 
N. convergens Wkr. Pale ochreous, forewing slightly strewn with dark brown scales. A brown spot 
at the cell-end, costal margin red-brown. A brown oblique line from the costal margin shortly before the apex 
to the centre of the inner margin, another line to the margin above the tornus, bent below the costal margin. 
Hindwing reddish-brown. Expanse of wings: 50 mm. India. 
N. cepphica Swh. Palpi longer than in the preceding species. Dark brown, thorax black at the end. 
Forewing pale red-brown, costal margin and distal margin dark brown. An indistinctly undulated broken 
postmedian black line, incurved at the lower cell-end, extends to the centre of the inner margin. Abdomen 
and hindwing pale brown. The forewing is sometimes entirely clouded with blackish. Expanse of wings: 
18 mm. India. It was not before me. 
N. basalis Wkr. Fawn-coloured, basal third of forewing dark brown, distally bordered by a blackish 
band which is edged with white outside, a thin whitish submarginal transverse line. Expanse of wings: 30 mm. 
East Indies. The species can no more be identified, because the type has been lost. 
N. furva Wil. Pale brown, forewing speckled somewhat darker, a diffuse blackish spot in the ceil and 
an oblong similar one below it, extended to the inner margin, traces of a dark submarginal line. Hindwing and 
under surface blackish-grey. Expanse of wings: 19 mm. Formosa, in August. The species seems not to belong 
to this genus, perhaps to Spatulifimbria (p. 719). 
N. orthosioides Wkr. (89 f) is brownish-red. Forewing partly clouded blackish, scantily scaled blackish, 
with a black cross-vein dot and an undulated submarginal line of dots. Abdomen, hindwing, and under surface 
grevish-brown. Expanse of wings: 24 mm. Borneo. 
78. Genus: Ufatarosa gen. nov. 
Structurally the same as the preceding genus, but vein 11 of forewing arises very far basad from the 
origin of 2. Palpi somewhat more cylindrical and pointed. Type of genus: N. subrosea Wil.
