688 BIRTHAMA; TOANA; PLONETA. By Dr. M. Heking. 
P. ocularis Luc. (= eumela Low., discotypa Trnr.). Forewing triangular, with a straight costal margin, 
brownish-grey, with some darker scales, a large circular blackish-brown spot, which is edged with white 
posteriorly, on the inner margin from near the base to the centre. A similar white-edged spot at the costal 
margin from 3 / 5 to near the apex. Hindwing dark grey. Expanse of wings: (J) 22 mm. North Australia. 
P. binocularis sp. n. (85 k). Fore wing pale ochreous, base somewhat brown-spotted, with an indistinctly 
defined brown curved median band bearing a round still lighter yellowish spot at the cell-end and a smaller 
one above the inner margin, and being contiguous below the centre with the yellowish-brown marginal area 
which is bordered by a dark brown line; this marginal area projects above vein 7 in a sharp tooth towards 
the base. Hindwing brownish-red, with an ochreous basal spot. Expanse of wings: 20 mm. Bougainville, January. 
cJ type from Buin (Thing Museum). 
27. Geims: KiWBiama (inch Nirma v. Eecke). 
Antenna of $ pectinate as far as %, bare in the $. Palpus moderately long, scarcely projecting beyond 
the frontal tuft. Posterior tibiae with 2 pair of spurs. 7 of forewing sometimes separated from 8 + 9, 10 stalked 
with 8 + 9, 11 bent very near towards 12. 6 + 7 of hindwing stalked or from the same basis, 8 anastomosing 
long with the anterior edge of the cell at the base. Most of the species formerly ranged in this genus were 
wrongly placed here, because 11 of the forewing was straight. 
B. obliqua Wkr. (85 k). Forewing brownish-pink, with a violettish-black oblicpie line from the apex 
to the inner margin near its base, anteriorly somewhat convex (anteriorly concave in similarly marked species 
of Thosea!). A more or less indistinct submarginal line broken into two parts also proceeds from the apex. 
Hindwing brownish-pink. Expanse of wings: 30 mm. Borneo. 
B. obliquifascia Hrnps. (85 i). Scheme of markings as in obliqua. Ground-colour pale ochre, more or 
less tinged reddish. Submarginal line in the $ often widened into a dark spot at the place where it is broken. 
Wings often more or less dusted with dark brown. Expanse of wings: 34 mm. Ceylon, Borneo, Celebes. 
B. rubicunda Wkr. ( = psychidalis v. Eecke) (85 k). Type of genus of Nirma v. Eecke , but hind tibiae 
with 2 pair of spurs, exactly corresponding to the preceding species in structure. Body brownish-red, head 
and dorsal line orange-red. Forewing brownish-red, with dark veins, dusted somewhat grey. Hinclwing lighter 
brownish-red. Expanse of wings: 20—22 mm. Sumatra, Borneo, Malacca. 
B. nigrina sp. n. (90 d). Body and forewing blackish violet, partly strewn with silvery scales. Forewing 
relatively scantily scaled, veins darker. Marked deep black: the basal sling 1 a to 1 b, the cross-vein and a 
streak in the middle of 2. A broad submarginal band of bluish-grey scales. Hindwing scantily scaled grey. 
Expanse of wings: 23 mm. Borneo, in December. <$ type from Butik-Raja in the Hamburg State Museum. 
B. rosea de Joann. (85 d). Dark reddish, fore wing with a blackish oblique line extending straight 
from the apex to the inner margin before its centre; at the same place at the costal margin, a thinner blackish 
subterminal line extends almost vertically to the tornus. Expanse of wings: 32 mm. Tonkin. — It was described 
as Geratonema, but it is apparently closely allied to obliqua from which it differs in the straight subterminal 
line of the forewing. 
28. Genus: Ton tin Wkr. (Goana v. Eecke.) 
Palpus smooth, upcurved, not projecting beyond the vertex, 3rd joint conical, % the length of the 
second. Antennae of <$ only pubescent. Legs short and smooth. Wings short and broad. Forewing pointed, 
costal margin straight, distal margin somewhat concave below apex. (It was not before me; position doubtful.) 
T. semiochrealis Wkr. Ochreous, head and thorax darker, abdomen and hindwing whitish ochreous. 
Wings with brown marginal dots. Forewing with 2 brown dentate antemedian and postmedian transverse 
lines. Expanse of wings: 37 mm. Borneo. 
29. Genus: I®l©neta Sn. 
Palpus moderately long, upcurved, not projecting beyond the frontal tuft. Antenna of $ pectinated 
to the end, the pectinations growing longer towards the middle. Hind tibiae with 2 pair of spurs. Forewing 
concave below the apex, vein 1 c strongly curved in the middle, 2—5 at great distances from each other, 6 
and 7 close together from the cell; the long-stalked 8 + 9 comprise the apex. Cell strongly compressed at 
the base. 6 + 7 of hindwing stalked, 8 anastomosing with the anterior edge of the cell only after the centre 
of the cell.
