P. trimacula Walk. (li). d* with wliite, ? with yellow anal tuft; collar and abdomen shiny copper- trimacula. 
colour; forewing blackish, with 3 indistinct yellowish spots, one at the base small, the second in the middle 
large, transverse, the third small, before the apex. — New South Wales. 
5. Genus: Ksocraitahia gen. nov. 
$: in form reminding one of Heteropan. Head broad, frons shightly convex; antenna thin, pectinated, 
the pectinations rather far from one another, reduced to small teeth on the last segments; palpi very short. 
Fore wing truncate; the 3. and 5. subcostals or only the 3. absent; discocellular in the hindwing oblique from 
the costa to the lower angle of the cell and scarcely angled, I. radial absent, 2. subcostal close to the 2. radial. 
— Four species from New Guinea, partly true copies of Lithosids and Micros; only the ?? known, and 
indeed only one specimen of each, all discovered by A. S. Meek. 
I. melaleuca Ii.&J. (li). Head and collar light yellow, thorax white, abdomen green-black, legs meiaieuca. 
dirty yellow. Forewing above white, outer margin and distal part of the costal margin brown-black, the 
angulated band abruptly broken off. Hindwing slate-grey, slightly bluish, covered with white scales at the 
base and posteriorly. Under surface slate-grey, slighly bluish, marginal band of the forewing not so sharp 
as above, hindwing with white scales before and behind the middle. Neuration: 1. and 2. subcostals of the 
forewing free, 3. subcostal stalked with the 1. radial, and the 2. radial with the 3. — In the mountains of 
British New Guinea, at an elevation of over 6000 ft. 
I. lutea spec. nov. (li). Resembling the preceding species in the shape of the wings. Head, collar lutea. 
and forecoxa yellow-red, thorax yellowish white, abdomen white, underside of the body and the legs dirty 
reddish white. Forewing above pale purple-brown, the under scales white, the partly rubbed off places con¬ 
sequently appearing white; hindwing pure pale yellow, with some brown scales at the apex. Under surface 
pale yellow; forewing almost white, from the apex of the cell distad brown, this marginal band gradually 
narrowed posteriorly. Neuration: as before, but the 2. and 3. radials of the forewing not stalked. — Aroa 
River, British New Guinea, 4 —5000 ft., in May, 1905. 
I. tricolor It. & J. (2 b). Body and base of the forewing blue-black, somewhat glossy, the flattened tricolor. 
frons, the collar and a broad subbasal band on the forewing whitish yellow. Wings black; forewing slightly 
bluish, with dark yellow dot before the apex; hindwing with very broad white area, extending from the 
costal margin to the anal angle. Under surface similar to the upper, the light markings more extended. 
Neuration: 1. subcostal of the forewing very far removed from the end of the cell, anastomosing with the 
costa, 2. near the apex of the cell, 4. from the angle of the cell, stalked with the 1. radial, 2. and 3. radials 
also from the cell. — In the mountains of British New Guinea, at an elevation of over 6000 ft. 
I. apicalis spec. nov. (li). Head and thorax green-blue, abdomen dark green; hindwing above and apicalis. 
beneath, rather more than half the forewing beneath and the breast and legs glossy blue. Forewing above 
purple-black, in the basal third covered with blue and green metallic scales, the apex indistinctly red-brown: 
apex of the hindwing and on the under surface a broad marginal band on both wings red-brown. Tip of 
the abdomen grey-yellow beneath and at the sides. Neuration: forewing with 4 subcostals, 1. and 2. free, 
3. absent, 4. and 5. stalked with the 1. radial, 2. and 3. radials likewise stalked. Length of the forewing 19 mm. 
- On the upper course of the Mambare River, in the north-eastern part of British New Guinea, at. a height 
of about 5000 ft.. February, 1906. 
6. Genus: TEeteropau Walk. 
Small Lycaenid-like insects, with long produced head. Frons pointed. Antenna in c? and S pectinated, 
often laterally compressed, especially in the ? of some species, the pectinations thick and scaled at the base. 
Palpi long and thin, projecting beyond the edge of the frons. Anal claspers of the c f sole-shaped, closed 
together. Forewing truncate, the area between costa and subcosta broad, 1. and 2. sobcostals free, 3.—5. 
stalked, 3. far proximal to 5., sometimes wanting; 1. radial from the stalk of the subcostal or like the 2. and 
3. from the cell; 2. and 3. radials of the hindwing separated or stalked, which occurs in individuals of 
the same species. The sexes are similar to one another, yet the cfcf have almost always a distinguishing 
mark on the wings, either a scent-organ or a specially coloured spot. — Distributed through the whole 
Oriental Region from Ceylon and Burma to Fiji, but only a few species are known as yet; most of them 
inhabit New Guinea. Not yet found in Australia and North India. 
H. scintillans Walk. (2a). Antenna deep blue, forewing bluish grey-brown, distal margin coppery, scintillans. 
with a marginal line composed of shiny light blue scales. Hindwing pale metallic blue. Under surface white- 
grey or more brownish, the margins brownish, outer margin coppery, a black basal streak on the costal margin 
of both wings and a central streak on the hindwing metallic, hindwing in the d* with a black-scaled fold before 
the abdominal margin. Body beneath glittering silver-colour. — Ceylon; South India; Burma; Nicobars. 
H. cupreatus Hamps. (2a). Body and forewing coppery brown; abdomen and hindwing darker blue than cupreatus. 
in scintillans. No black-scaled anal fold on the underside of the hindwing. — Ceylon. 1 cT in the British Museum.
