N. flavicaput Rothsch. Antennae red-brown; head and collar sulphureous, thorax and abdomen dark 
brown. The forewings are chestnut-brown, with a purple and blue reflection; the basal three fifths exhibit 
a large, sulphureous spot extending from the subcosta to the proximal margin; in the middle of the costal margin 
a large, long-haired scent-organ. The hairy hindwings are sooty brown, with a large, yellow, wedge-shaped 
spot at the costal margin near the base. Length of forewings: 8 mm. Kumusi River in North East British 
New Guinea (May). 
N. collateral^ limps. (16 d). In the basal half of the forewing deep golden-yellow, distally copper-red, 
base and margins black. Hindwing yellow with a broad black border. Kapaur in South West New Guinea. 
74. Genus: Parttseaptia B.-Bale. 
Palpi very small; proboscis absent; antennae very fine and small, doubly combed; wings of a uniform 
width; costa very convex; border as far as the anal angle decreasing. On the forewing vein 2 rises a little behind 
the middle of the cell and is curved at the base, 3 petioled with 4 from the cell-angle, 6 rises below the upper 
angle, 7, 8, 9 petioled, 7 and 8 from near the margin, 9 from a good distance behind the cell, 10 and 11 separate, 
the latter curved; on the hindwing 2 rises far before the angle, 3, 4, 5 and 6 with a long footstalk, 8 separately 
from the base, then flawed to a short anastomosis with 7. Type: biplagaia. 
P. biplagata B.-Bak. head and collar light yellow, thorax yellow with a purple stripe, abdomen 
light grey. Forewing light yellow, basal half purple-red, towards the base decreasing in the direction of the 
costa, at the costa a yellow costal spot. Straight through the wing a large, purpie-red post median spot leaving 
the border light yellow. 16 mm. Babooni. 3000 ft. September. 
75. Genus: Kyrsia Wkr. 
Proboscis well developed; the short palpi erect; £ antennae with ciliary pencils. The narrow forewing 
differs in the venation from the preceding genera by the 1st median and 3rd radial rising on a joint footstalk, 
whereas the 2nd radial is absent ; the 1st subcostal vein comes from below the upper cell-angle; the 3rd is absent, 
the 2nd, 4th and 5th rise on a joint footstalk, only the 1st rising separately from the cell. On the hindwing 
the 1st median and 3rd radial rise on a joint footstalk; the middle radial comes from the lower cell-angle and 
is strongly curved; subcostal and 1st radial rise in the from the same place in the upper cell-angle, whilst 
in the $ they are petioled. In the the costal margin is excised before the apex. 
B. aurantiaca Snell, is very much like the following species and differs above all by the yellow spot 
being extended to the costal margin. The body is black, the shoulder-covers are spotted orange, the anal tuft 
and venter whitish. The basal two thirds of the forewing are yellow, only the base somewhat black; the distal 
bordering of the yellow colour runs obliquely and is dentate at the lower cell-end and on the submedian fold; 
an antemarginal, orange-red spot is narrowed towards the proximal margin. Hindwing yellow, distal and 
proximal margins black. Malacca, Borneo, Sumatra. In Javanese specimens, subsp. javana Rothsch., the 
orange-red marginal spot is much more extensive than in the Sumatran type. — The larva, according to Piepers, 
lives in Batavia on Mango, in July and August; it is orange on its head and the two first and last segments, on 
the others above greenish, on the 3rd and 10th segment above black. Hairing white. 
B. dotata Wkr. (= princeps Fldr.) (16 d) is very much like aurantiaca and easily discernible by the 
black costal margin; the body is also quite black and the shoukler-covers unicolorous. Hindwing in the B blackish- 
brown with a light costal margin and an orange spot below it; the $ exhibits a much larger, triangular, orange 
spot in the disc. Celebes, Amboina, Batjan. In the name-type the basal area is as broad as the thorax, the 
black costal margin broader than in the Celebes-race, the orange-red submarginal band posteriorly narrowed. 
In subsp. celebensis Rothsch. the black basal area of the forewing is only half as broad as the thorax, the black 
costal margin extremely narrow, and the orange-red submarginal band extends broadly to the proximal angle; 
the orange colour of the hindwing is in the <$ only indicated by few scales; from Celebes. — subsp. papuana 
Rothsch. from British New Guinea (Milne Bay and Kapaur) has a much broader submarginal band reaching 
the proximal margin; the yellow area on the hindwing is very extensive in both sexes. 
B. ornata Rothsch. Pronotum and a spot on the shoulder-covers yellow. Very much like dotata (16 d), 
the yellow colour is paler, as broad as in aurantiaca', the costal margin bordered with black; the orange-red 
marginal band reaches the proximal margin and is here somewhat narrowed, but not pointed, above about 
2 mm broad. Hindwings as in dotata papuana, the proximal margin broadly black, but not distinctly defined. 
Length of forewings: 10 mm. Humboldt Bay in Dutch New Guinea, in September and October.
