712 THOSEA. By Dr. M. Hering. 
vein with a large blackish spot, hindwing dark grey. Expanse of wings: 35—40 mm. India, South China, 
Formosa. — borneensis subsp. nov. has a light reddish-brown ground-colour dusted lilac grey in the basal half. 
It is separable from the similar loesa (88 k) by the abdomen projecting far beyond the hindwing. Borneo, 
type from Labuan in the Berlin State Museum, where there is also a $ from Sumba. 
Th. rara Swh. (88 k) is very similar to sinensis, the transverse line of the forewing parallel to the margin, 
bordered with whitish inside, more intensely shaded dark outside in the marginal area. Central dot indistinct 
or absent. It seems to be doubtful whether it belongs to sinensis or not, both living in the same districts, 
though rara goes as far as China. Expanse of wings: 30—38 mm, mostly somewhat, smaller than sinensis. 
India, South and North China. 
Th. unifascia Wkr. Like sinensis (88 k), but the ground-colour of the forewing is red-brown instead 
of grey. Expanse of wings: 36—40 mm. India. 
Th. loesa Mr. (88 k) is likewise very similar to sinensis, forewing red-brown, but the dark transverse 
line is somewhat nearer to the central dot and originates somewhat farther basad on the forewing. (Our figure 
has been made according to an original sketch by Moore.) Expanse of wings: 30—40 mm. An oblique violettish- 
grey shadowy band is sometimes in the centre of the inner margin of the forewing. — Larva green, with a white 
or yellow dorsal line and numerous green, red-spined appendages; it lives on a great number of cultivated plants. 
India to Borneo. 
Th. cervina Mr. (89 a). Forewing very dark red-brown, basal half somewhat darker, central dot rather 
inconspicuous. The dark transverse line is feebly bordered with a lighter colour distally and extends in a basally 
convex bow from the costal margin near the apex to the tornus. Hindwing dark brown. Under surface light 
brown, scantily dusted with black. Expanse of wings: 28 mm. — Larva green, with a purple dorsal line which 
is expanded in the middle into two large brownish-yellow spots, one of which is bordered with red, polyphagous. 
India. Ceylon. 
Th. duplexa Mr. (89 a) is very much like cervina, forewing more greyish, transverse line somewhat 
more convex, central spot larger, distinctly black. Both sexes before, me. Expanse of wings: 26—35 mm. Ceylon. 
Th. ( ?) conspersa Btlr. Whitish-brown, forewing finely dusted with dark brown, a spot in the cell and 
a larger one at the cell-end, a submarginal curved line of fused black dots, apical margin blackish. Hindwing 
whitish, costal margin dusted with brown. Expanse of wings: 15 mm. Formosa. It has not been before me and 
may not belong to this genus. 
Th. curvinervis sp. n. (89 a) strikingly resembles Th. monoloncha, but vein 11 of the fore wing is bent 
towards 12. Smaller than monoloncha (89 a). Apex of forewing somewhat more rounded. Forewing variable, 
from light to dark violettish-brown, with an almost straight dark transverse line which is bordered with light 
inside and is posteriorly somewhat less divergent with the margin than in monoloncha. Hindwing from yellowish 
ochre to blackish-grey. Expanse of wings: 20—22 mm. £ type from the Aroa R., New Guinea (Tring Museum), 
also New Ireland and New Hanover. 
Th. penthima Trnr. (= pyrrhoea Low.) (89 a). Forewing red-brown, the central third from more or 
less violettish-grey to whitish, central dot present or absent; the dark transverse line behind it is bordered 
with light inside and almost parallel to the margin, slightly convex distally. Hindwing red-brown. Expanse 
of wings: 24 - 34 mm. — Larva on Carcya australis. Australia. 
Th. monoloncha Meyr. (= axiothea Hulst) (89 a). Very similar to penthima, very variable. Forewing 
from red-brown to dark violettish-grey, basal third less prominent. — In f. nigrifasciata form. nov. the forewing 
exhibits a jet-black median band which is terminated by a whitish narrow transverse line distally bordered with 
dark (qtype from the Kumusi River, in the Tring Museum); — in nigribasis form. nov. the whole basal two 
thirds are jet-black, whereby the species resembles the following caliginosa (<J type from the Astrolabe River, 
British Museum). Expanse of wings: 26—35 mm. New Guinea. 
Th. caliginosa sp. n. (89 a). The basal two thirds of the forewing are purple blackish, not bordered 
by light lines as in nigribasis, the marginal third brownish ochreous, with a diffuse blackish spot between veins 2 
and 5, hindwing and under surface brownish ochreous. Expanse of wings: 34 mm. Amboina. ($ type in the 
Berlin State Museum.) 
Th. fluxa Sn. (89 b). Forewing brown, with a black central dot and a blackish oblique shadow in the 
centre of the inner margin. The transverse line is at first somewhat convex below the costal margin, then 
straight to the inner margin before the tornus, distinctly bordered with brown outside, more diffusely blackish 
inside. Dusted with black in the centre of the marginal area on the veins 3—5. The transverse line of the $ is 
only dark. Expanse of wings: 30—33 mm. Java. 
Th. asigna v. Eeche (89 b). Similar to fluxa, larger, transverse line farther basad, pale, diffusely bordered 
with blackish outside, straight. Marginal area without black dusting, but all the veins in it lighter. Expanse 
of wings: 35—42 mm. Sumatra, Borneo. 
Th. sythoffi Sn. Body and forewing whitish-grey, forewing with 2 fused indistinct brownish-grey 
antemedian spots, without the cross-vein dot. Transverse line very broad (1 mm), bordered by a white line 
inside, distal margin somewhat whitish. Hindwing light grey. Expanse of wings: 27 mm. Java. It was not 
before me.
