ALTHA; MAMBARA. By Dr. M. Hering. 
plumbifusa. Rll. plumbifusa Hmps. (86 f). Body ochreous with a brown tint. Forewing ochreous, dusted somewhat 
silvery, especially at the costal margin. An indistinctly defined undulated reddish-brown transverse line 
traverses the cross-vein, then recurved to the origin of vein 2, then to the inner margin before the middle. 
Subterminal line blackish, excurved below the costal margin, then broken up into dots as far as vein 5, 
then only indicated by blackish scales to the tornus. Hindwing ochreous. Expanse of wings: 20 mm. Assam. 
- Described as Cania, antenna of <$, however, pectinated to the apex, therefore it probably belongs to this 
genus. 
14. Genus: Altlaa Wkr. 
Palpi short, rising appressed; antenna of pectinated in the basal third, then bare, quite bare in 
the Hind tibiae with 2 pair of hardly visible spurs. 7—9 of forewing stalked, 10 together with the stalk, 
or stalked or separated, 11 bent very near to 12. 8 of hindwing connected with the anterior edge of the 
cell near the base, 6 and 7 distantly separated. By the latter mark as well as the basally pectinated G an¬ 
tennae the species are distinguished form the habitually similar species of Narosa. 
nivea. A. nivea Wkr. (86 f and Vol. II, pi. 50 b). Wings pure white, with 2 black marginal dots below the 
apex. Fore wing with a black dot beyond the lower cell-end and a very indistinct scanty brown spotting, 
sometimes an indistinct brownish subapical line at %. hinder surface white, with the black marginal dots 
of above, costal margin of forewings sometimes black. 25 — 30 mm. India, Ceylon. 
lacteola. A. lacteola Swh. is separated from nivea by the more intense brown marking of the forewing, some¬ 
times without the black cellular dot. The veins and some transverse lines appear white on the brownish ground. 
Under surface always without the dark costal margin. Expanse of wings: 24—30 mm. India, Ceylon. - 
pura. pura Sn. (86 f) is still more intensely marked brownish-grey, the apex of the forewing is less rounded, the 
melanopsis. race somewhat larger. Java, Sumatra, Banguey. — melanopsis Strd. is scarcely separable from pura. , only some¬ 
what larger (G 26 mm), marginal line of hindwing pure white, only a small dot below the apex is black. 
Formosa to North India. 
a dal a. A. adala Mr. (86 f). Similar to lacteola, the dark marking of the forewing more orange brown, appearing 
in more distinctly separated spots, a black dot behind the lower cell-end may sometimes be absent. — Larva 
pale green, with bluish-green lines and spots, and a lateral row of black spots, on Anona and Bankinia. Cocoon 
oviform, whitish. India, Tonkin, Java, Sumbawa, Borneo, and Celebes. 
pcralbida. A. peralbida Swh. (= peralba Hmps.). White; patagia at the end, abdomen dusted brown and black 
at the base and end and beneath. Basal area of forewing dusted black, a black longitudinal streak at the end 
of the posterior edge of the cell, and some blackish dusting in the apical area. Expanse of wings: 26 mm. 
Poona (India). 
rufescens. A. rufescens Swh. (86 f). Forewing with very widely expanded orange colouring, so that it looks very 
much like Narosa conspersa, but easily discernible by the black cellular dot. Hindwing more or less darkened 
grey. Expanse of wings: 20—25 mm. Ceylon. 
contami- A. cositaminata Hmps. (86 f) is very similar to rufescens, vein 10 of forewing from the cell-end, separated 
nata. f rom j j, j n rufescens. Hind wing predominantly blackish. Both wings exhibit a continuous row of black marginal 
dots. Expanse of wings: 28 mm. Nilgiris. 
circum- A. circumscripta sp. n. (86 g). Antenna of with pectinations gradually decreasing in length towards 
scripta. the 
apex. Body yellowish-grey, thorax whitish above. Forewing brownish, some places dusted with blackish; 
a transverse zigzag line from the centre of the costal margin to the inner margin before the centre; in the 
angle of the origin of 4 and 5 there is a black dot situate at the anterior edge of a pure white spot. A brown 
undulate-dentate preapical transverse line extends curved to the tornus. Margin above tornus with some 
black dots. Inner margin dusted with black like a spot at the tornus (sometimes also in the middle). Hindwing 
yellowish-grey, with dark grey hair at the inner margin. Expanse of wings: 17—20 mm. Minahassa. S f yP e 
in the Berlin State Museum. 
15. Genus: Mambara B-Bak. (Hypoblechra Trnr.) 
Palpi moderately long, rising. Antenna of G long pectinated at the base, plain at the end. Hind tibiae 
only with terminal spurs. 7 of forewing separated from the stalked 8—10, 11 bent near to 12. 6 -f- 7 of liind- 
wing from the same place or stalked, 8 anastomosing with the anterior edge of the cell near the base. 
1. Anterior hips without a white spot at the end. Forewing with a light dot 
at the cell-end or distal! y to it. 
delocrossa. M. delocrossa Trnr. (85 g). Costal margin of forewing rather straight, apex less rounded, dark brown, 
with a silvery white transverse line at the base, a whitish subterminal line behind which the marginal area 
is grey and before which there is a small whitish spot. Hindwing dark brownish-grey. Expanse of wings: 
20 mm. North Australia.
