[Continued from p* 160,]

HOHOPSYCHE, gen, nov.

Aspect of the Horaopterous genus Flaia y but most nearly
allied to Barsinella. Wings when closed taking much the
same position as in Cacoecia : primaries broad, with arclied
costal margin, woolly, semitransparent, with strongly defined
widely separated veins ; discoidal cell long and narrow ;
costal vein short, not extending to the middle of the margin ;
subcostal with four branch es, the first given off some distance
before the end of the cell, the others beyond it ; one radial
emitted from the discocellulars (which are very oblique), so
that it seems to be a fourth median branch ; the three median
branches emitted widely apart : secondaries elongate, almost
triangular, but with the angles rounded off, coarsely scaled,
semitransparent, strongly veined ; the cell rather long, but
not particularly narrow, the subcostal forking beyond it ;
discocellulars angulated ; no radial vein. Body woolly, but
the thorax, which is broad and short, almost naked above, so
as to show its sutures*; anal tuft divided, very full, with the
male harpagones very long, though slender; antennae with
an extremely long woolly basal joint, the remainder being
slender, naked, and with an inner series of fine very short
setse ; palpi very small and slender j proboscis rather large ;
legs thick, but rather long, the tibi^ with short, rather slender,
terminal spurs*

43. Homopsyche nudarioides 7 sp, n.

White ; the basal half of primaries with three equidistant
pale-brown spots on both the costal and internal borders ; a
small darker-brown spot at the end of the cell ; veins tipped
with brown. Expanse of wings 20 millim*

New Britain.

44, Pallene ? metalligera } sp. n.

Primaries above ochreous ; the base and a large oblique
spot before the middle of the internal border purplish opaline ;
an ill-defined arched discal opaline silvery line expanding below
the radial vein into a broad silver patch, which fills the ex-

46. Arm immaculate sp* n,

$ . Cream-coloured, with the exception of the upper surface
of the primaries ^ which is ochreous ? and the pectinations of
the antennae ? which are testaceous. Expanse of wings 21
millim,

Duke-of-York Island.

The large deeply -pectinated antennae at once distinguish
this from all species of Ariawa.

47. Syniherata Godeffroyiij sp. n.

g , Ochreous ; primaries above with the costal border and
subapical area irrorated with brownish scales, giving them a
sordid appearance ; basicostal border lilacine greyish ; lilacine
greyish stripes as follows * ■ — a deeply dentate zigzag stripe
from below the first median branch to the internal margin ?
a short irregularly dentate-sinuate stripe from costa across the
external third of the cell, and two parallel undulated stripes
enclosing a band of colour slightly paler than the ground-
tint across the disk ; a small ocellus with blackish-edged
hyaline white centre, and a white iris encircled by a lilacine-
greyish line ? at the end of the cell ; costal area at apex
broadly lilacine greyish, crossed by a blackish spot ; a sub-
marginal series of squamose blackish dashes : secondaries with a
small triangular blackish spot with pale flesh-coloured border
at the end of the cell, and immediately followed by an arched
series of about nine large unequal diamond-shaped spots, out-
lined in lilacine greyish ; a dentate-sinuate flesh-coloured
stripe, spotted with blackish between the veins, running

* This coloration is produced by a combination of reddish-chocolate
and white scales.

parallel to the outer margin across the disk ; a submarginal
series of pale grey dashes : antennaa ferruginous j collar
lilacine grey* a little more chocolate-tinted than the markings
on the wings, and with whitish posterior margin. Wings
below blotched and banded with chocolate- colour, the most
prominent markings being two central bands, a large apical
blotch on the primaries, a subapical blotch and a discal series
of spots on the secondaries, a submarginal series of dashes,
and the small ocelli \ the basicostal areas are washed with
clouded flesh-colour : venter with a series of brown dots on
each side. Expanse of wings 147 millim.

New Britain,

Allied to S* dtsjuncta (Anthercea disjuncta. Walk.) ; the

Icepotdes from Borneo is also a Syntherata*

48. Eumeta maxima^ sp. n.

$ , Primaries pale red-brown, with the subcostal area, in-

49, Zenzera bubo 7 sp, n.

? * Allied to Z. sirix ; pinky white, clouded with pale
purplish brown 3 reticulated and spotted with black j the pri-
maries with the base, a broad costal patch at about the basal
third, a series of costal spots beyond the latter, a large patch

Expanse of wings 158 millinu
New Britain.

50. Phcmaca? cossoides 7 sp. n.

Aspect of a Cryptopkasa (see 0. alhicosta) } but differing
entirely in structure, which is that of a Notodont : primaries
silvery white, the basal two fifths more or less clouded with
red-brown, the outer margin of the red-brown area inarched j
an indistinct curved stripe of the same colour crossing the
wing immediately beyond the cell ; costal margin and external
border also red-brown : secondaries smoky grey, with white-
tipped fringe ; head and collar smoky grey ; thorax whitish ;
abdomen bronze-brown. Wings below brownish, with bronze
reflections j body sericeous white. Expanse of wings 29-31
millini.

Duke-of-York Island and New Britain,

As the type of Fhanaca is too much broken for me to de-
cide its sex, and as it possesses simple antennse, whereas both
specimens of P. ? cossoides are males with tapering pectinated
antenna, the generic identification of this species must for the
present remain doubtful. In neuration it agrees fairly well
with Phanaca } though, in this respect, one of the specimens
exhibits a singular aberration, the upper radial of the left
primary being forked,

51. Acontta inconcisa 7 sp. n.

Allied to A. signifera. Above sordid silvery white : pri-
maries crossed from the middle to the apex by a forked
Y-shaped bronze-brown band, the lower half ill- defined j a
brown spot at base of costal border ; external border irregu-
larly speckled with brown ; a marginal series of brown dots ;
fringe cream-coloured, flecked with brown and black and
tipped with white : secondaries with greyish external border :
fringe cream-coloured, tipped with white and traversed by a
grey line. Primaries below shining grey, costal border cream-
coloured, grey-speckled, spotted with black above the end of

the cell and at the apex ; fringe cream-coloured, flecked with
blackish: secondaries with the costal half cream-coloured,
grey-speckled j a blackish discocellular spot and abbreviated
discal line ; a marginal series of linear black dots : body
creamy white, Expanse of wings 18 millim.
Duke-of-York Island.

52. Callopistria insularis } sp. n.

Primaries above cream -coloured, silvery in certain lights,
irregularly spotted and striped with sandy yellow j the blackish
markings squamose, ill-defined, similar to those of G. exotica^
excepting that the spot at the end of the cell and the marginal
spot on the second median interspace are pnpilled with silvery
white ; the other marginal spots are also depressed, olivaceous,
and extend to apex ; the two slender black lines converge in
the same manner upon the interno-median area :, secondaries
shining greyish brown ; fringe sandy buff, traversed by an
imperfect grey line : head white ; collar testaceous, thorax
opaline white, abdomen opaline greyish. Wings below almost
exactly as in 0* exotica : body creamy whitish ; femora, espe-
cially of the hind pair of legs, fringed with dark greenish-
grey hair ; a bifid blackish tuft on the posterior tibiae. Ex-
panse of wings 28 millim,

Duke-of-York Island.

Nearest to G* chloriza of Java.

53. AnopMa $ericea } sp. n*

Nearly allied to A. oUvescens } but differing from it in the
greater prominence of the black markings and the absence
of any white markings on the upper surface, in which re-
spects It more nearly approaches A* Ramburii of Europe.
From the latter it may be at once distinguished by its glossy
primaries, the absence of white marginal markings on the
under surface of these wings, and the brown costal border
of the secondaries on the under surface. Expanse of wings
36 millim.

Duke-of-York Island.

54. Pwrbia mwscigera } sp, n.

Closely allied to P. discr spans ( Ophideres discr spans ? Walk.),
but differing in the pinker tint of the primaries, on which the
green spots are more vivid^ the much more strongly angu-
lated dusky stripes across these wings ? the total absence of
the two wiiite spots on the median interspaces and of the
blackish nebula beyond them, the absence of the whitish

costal border of secondaries, and the smaller black lunate spot
on the disk of these wings. Expanse of wings 89 millim.

New Britain.

As Mr. Moore has figured P. discrepans in his revision of
the Ophideridse, there will be no difficulty in identifying the
species described above.

55. Ctypansa bocanidia^ sp> n,

Lilacine grey ; the wings traversed by two more or less
diffused chocolate-brown stripes , the first at about the basal
third oblique and regular, the second irregularly angulated,
bounded externally by a series of white points, and crossing
the centre of the disk ; fringes, especially of the male, bluish
grey and spotted with chocolate ; primaries with a black spot
at the end of the cell. Under surface dark smoky grey, the
wings crossed by three equidistant dusky stripes, the outer-
most of which is bounded externally by a series of creamy-
white spots. Expanse of wings 41 millim.

Duke-of-York Island.

The female is a little darker and more purplish than the
male, and the stripes on the upper surface of its wings are
darker and more diffused.

56 * Heleona tyrianthina 7 sp, n.

c?. Allied to H. mars of Boisduval i^=fenestrata J Swains.),
shining blue-black ; primaries with a trifid bluish- white hya-
line band before the middle ? a small spot at the end of the
cell ; three spots in a subapical series and an oblong spot near
the external angle upon the first median interspace : secon-
daries with a broad belt of semitransparent creamy white

irregular discal series of bright orange spots : palpi, borders
of collar, and posterior margins of abdominal segments bright
orange ; abdomen more purplish, and the thorax more green-
ish than the wings ; anterior half of pectus and posterior half
of venter bright cadmium-yellow : legs below greyish, above
dark purplish ; posterior tibiee with large sandy-brown tufts ;
base of abdomen pale purplish brown, with a whitish posterior
border. Expanse of wings 92 millim,

Duke-of-York Island,

A pair of this beautiful species, from Few Ireland, was
presented to the collection by Messrs. Salvin and Grodman,
They both haye paler bodies (ash-grey with yellow bands)
than the example before me ; but as they are somewhat worn,
this may be due to fading, The female also has the entire

yellow, thus more nearly approaching H. jlavaia of Walker,
from Timor.

57- Boarmia repeiita 7 sp, m

(J . Pale brown, black-speckled ; wings with a lunule out-
lined in black at the end of the cells, almost filled in with

followed by conical marginal white spots on the secondaries ;
a slender interrupted black marginal line ; fringe touched
with pale buff at the base : primaries with a slender trans-
verse black discocellular line j costal border slightly brownish.

with reddish-testaceous pectinations ; proboscis ochreous ; legs
slightly yellowish, the anterior pair streaked with black. Ex-
panse of wings 44 millim,

Duke-of-York Island,

Nearly allied to H. erenaria*

59. Comibmna nivisparsay sp, n,

? . Emerald-green ; wings semitransparent, with a series

lines and two stripes placed alternately, the outer stripe form-
ing the external border, but separated from the margin by a
slender sordid white line ; the inner stripe of the primaries
marked with an oblique blackish dash upon the upper radial
interspace ; a marginal series of black dots. Under surface
bone-white, the markings somewhat confused, brown ; the dis-
cocellular spots even more conspicuous than above. Expanse
of wings 14 millim.

New Britain*

Notwithstanding its great resemblance to the other species
of Lycaugesj I hesitate to pronounce L. angulata finally a
member of that genus, on account of the decided angle at the
extremity of the third median branch of its primaries.
