H. albicosta Semp. (2 a). cf: body and wings above lilac grey, with shining metallic brown marginal 
line; hindwing anteriorly bluish white. Under surface white, the posterior half of the forewing and the 
margin, as well as the fringes of the forewing grey. Legs and underside of the body yellow. — 2 cdcd 
from Panaon, Philippines, in Semper’s collection. Not known to me in nature. 
H. fuscescens Dohrn. Head, upperside of the thorax and abdomen black-brown, occiput and sides 
of the thorax thickly, abdomen slightly blue-scaled; under surface whitish grey. Forewing above grey- 
brown, broadly edged with brown anteriorly and posteriorly and narrowly distally, with central silver streak. 
Hindwing grey-brown, with blue sheen. Under surface of the wings white, with light blue sheen, forewing 
edged with brown; hindwing with brown central streak, and a second brown streak below the cell; no 
scent-fold. — Sumatra, Borneo, Java. Perhaps only a form of H. argiolina. Unknown to me in nature. 
H. argiolina Oberth. (2a). Body blue-grey above, white beneath. Forewing above with grey-white central 
area, which extends from the base nearly to the outer margin; hindwing blue-white. Under surface as upper, 
but purer white. — Liva, South-West Sumatra, 1 c f in coll. Charles Oberthur. Not known to me in nature. 
H. lycaenoides Walk. (2 a). Forewing from the base to the lower angle of the cell white, with blue 
sheen, margin broadly purple-blue, the band purer blue proximally; hindwing blue, paler centrally from the 
base to the extremity of the cell. Beneath the forewing white in and below the cell, costal and outer 
margins blue, the white not extending beyond the upper angle of the cell; hindwing with white central patch. 
3. subcostal of the forewing present, cf beneath on the hindwing with a triangular purple spot posteriorly 
near the base, the abdominal margin brown-grey. —- New Guinea, Waigeu and the islands in the Geelvink Bay. 
H. dolens Druce. Similar to H. scintillans; forewing somewhat darker, distally a little coppery, 
without sharp metallic marginal line; hindwing blue, purple distally. Under surface grey-brown; forewing 
with whitish central patch, which is placed nearer to the costal than to the hindmargin; hindwing from the 
costal margin to the median nervure metallic, purplish distally. — Fiji Islands. 
H. anisus spec. nov. (2a). Forewing pale slate-blue, distal margin narrowly purple, with metallic 
marginal spots; hindwing unicolorous glossy blue. Forewing beneath purple distally and costally, in the cf 
brownish grey from the cell to the hindmargin, in the ? a white patch present, which occupies the posterior 
distal part of the cell and the adjoining part of the disc: fringes spotted in side-light; hindwing anteriorly 
and distally purple, posteriorly in the cf dirty yellow-grey and without a purple spot, in the ¥ posteriorly 
blue and centrally with a white patch reaching nearly to the margin. 3. subcostal of the forewing present. — 
British New Guinea, in the mountains, and on Woodlark Island. 
H. cyaneus spec. nov. (2a). Forewing blue, costal and outer margins glossy; hindwing blue, distally 
somewhat purple. Beneath purple-blue, with or without white; abdominal margin of the hindwing in the cf 
dirty yellow-grey, with purple spot at the base. The 3. subcostal of the forewing wanting; 2. and 3. radials 
of the hindwing usually long stalked, in one of our specimens both from the cell. British New Guinea, 
Louisiade Archipelago and Woodlark. — The Woodlark form cyaneus is on a average somewhat larger 
than the following form; the wings beneath are glossy purple-blue, without white patches in the middle. — 
difformis subsp. nov. from the Louisiade Islands St. Aignan, Rossel and Sudest, as well as the mountains of 
British .New Guinea, has on the under surface of the forewing a white median streak, which is purer white 
than in H. lycaenoides, and reaches nearer to the apex of the wing; the hindwing in the ? has also a light 
median streak which extends almost to the outer margin. 
H. alberti R. & J. (2a). Forewing green-black, with brass-coloured metallic spot before the margin; 
hindwing like the uperside of the abdomen glossy blue, fringes in the anterior half white-grey. Under 
surface shiny silver in the forewing from the base to the apex of the cell and in the hindwing beyond it, 
outer portion of the costal margin and the distal margin glossy purple-blue. 3. subcostal of the forewing 
present. Upper angle of the cell of the hindwing projecting far beyond the lower angle, 2. and 3. radials 
long stalked. — In the mountains of British New Guinea, I cf known. 
H. truncata. Forewing green-black, costal margin near the base strongly convex, then straight, 
distal margin incurved below the apex, before the margin a row of metallic spots, placed at a distance from 
the fringes. Hindwing rounded, with a brown-black marginal band with blue sheen. Beneath a white patch 
on the forewing, occupying the apical half of the cell (or somewhat more), costal margin of both wings 
glossy blue-green: hindwing white, the marginal band purple with a blue sheen. 3. subcostal of the forewing 
present, angles of the cell of the forewing at about the same height; in the hindwing its upper angle obtuse 
and widely projecting, the 2. and 3. radials stalked. New Guinea. truncata Oberth. from Jobi Island, in 
Geelvink Bay, has a large yellowish white spot on the forewing. — In chitonea subsp. nov.' (2b), from British 
New Guinea, the white spot of the forewing above is only indicated by slightly paler scaling; l ¥ known. 
H. appendiculata Snell, (2b). The largest known species. Forewing greenish brown, with metallic 
submarginal line. Hindwing purple-blue, especially beneath, in the cf 1 with abdominal fold and the anal 
angle terminating in a lobe; upper angle of the cell of the hindwing truncate, widely projecting. — Celebes.
