166 CHRYSALLACTIS; LIONOPTERA; EUROSIA. By Dr. M. Draudt. 
B. castaneola Hmps. has chestnut-brown forewings with a blackish-purple transverse band before 
the distal margin, which is much broader at the costal margin, but neither reaches it nor the proximal margin. 
Hindwing light chestnut-brown, at the base, proximal margin and border blackish-browri. Sangir. 
59. Genus : Clirysallactis Hmps. 
Differs from the very similar preceding genus by the fused two lower radial veins of the forewing. On 
the hindwing the 3rd radial and 1st median vein are fused. 
C. aureorubra Hmp.s. Forewings golden-yellow; base and marginal area coppery-brown, suffused 
with purple; the marginal area is proximally bordered by a darker, undulate line. Hindwings pale reddish- 
brown. Head, collar and mesothorax golden yellow, shoulder-covers and metathorax purple-brown. Abdomen 
blackish-brown, the large anal tuft grey. Louisiads. 
C. bipartita Rothscli. <$ antennae chocolate-brown, head golden-yellow, thorax and abdomen dark 
chocolate-brown. Anal tuft leather-coloured. Forewing golden yellow, base and distal quarter reddish-yellow 
chocolate-coloured; a blackish line separates the reddish-yellow, chocolate-coloured, distal quarter from the 
yellow principal part of the wing. Hindwing semi-diaphanous, greyish wood- or leather-coloured, distal third 
darker. Length of forewings: 12 mm. Biagi, Mambara River, British New Guinea; taken in February at an 
altitude of 5000 ft. 
C. apiciplaga Rothsch. antennae brown, head golden yellow, thorax chestnut-brown liued with 
an opalescent purple shade. Tegulae and prothorax golden yellow. Abdomen leather-coloured. Forewing: 
the basal 3 / 6 golden yellow with a chestnut-brown base, narrow black transverse lines enclosing yellow; the two 
distal fifths of the wing opalescent blue with two cinnamon-coloured spots and a large golden yellow subapical 
spot, a border of 1 mm width being dark brown. Hindwing abruptly truncated, of a light yellowish wooclen- 
grey colour, liued in a leather-colour. Length of forewings: 9 mm. On the Oetakwa River on the Snow Moun¬ 
tains, Dutch New Guinea; up to altitudes of 3500 ft., from October till December. 
C. niveiceps Rothsch. $ antennae yellowish-red, head snow-white, thorax chestnut-brown, tegulae 
snow-white, abdomen cinnamon-coloured wood-brown, the three basal joints liued light grey. The basal % 
of the forewing golden yellow, the base itself chestnut-brown, distally margined by a double transverse line, 
proximally white, distally black; distal third chestnut-brown; hindwings yellowish-grey. Length of forewings: 
8,5 mm. Haidana in the Collingwood Bay, British New Guinea; taken in April. 
60. Genus: liiciioptera Meyr. 
Comprises 2 small Australian species with rather narrow wings. Proboscis fully developed; the thin 
palpi are ascending, but do not project beyond the vertex; the tibial spurs are rather long. On the forewing 
the lowest radial vein is petioled with the upper median vein; the middle radial vein is absent, so is the 3rd 
subcostal vein. The 2nd, 4th and 5th subcostal veins are petioled. On the hindwing the 3rd radial and the 
1st median vein are either on a long pedicle or entirely fused; the 2nd subcostal vein and the 1st radial rise 
on a very short footstalk. 
L. crocodora Meyr. is very well distinguished by the peculiar shape of the hindwing.: the costal margin 
is very convex, between the subcostal and the 1st radial the distal margin is somewhat concave; also the proximal 
margin is very broad and exhibits in a fold a tuft of long reddish-yellow hair. The forewing is golden yellow , 
at the base and in the marginal third purple brown; in the latter there is before the apex at the costal margin 
a large, triangular, yellow spot; at the margin a white, interrupted line. Hindwing white, towards the margin 
brownish. Head and collar golden yellow, thorax purple brown. New Guinea. 
L. anguliscripta Luc. (17 b) has a normal shape of the wings; in the <$ the antennae are combed. 
Forewing yellowish-white with black, torn transverse lines and 2 large costal-marginal spots; hindwings blackish- 
brown. Queensland. 
61. Genus: -Eurosisi Hmps. 
The butterflies composing this genus belong to the smallest Lithosiids of an insignificant colouring. 
Discernible from the preceding genus by the straightly porrect, not ascending short palpi. On the forewing 
the 3rd radial and the 1st median rise separately, the 2st radial is present; the 3 lower subcostal veins are on
