the segments exhibit bright cobalt-blue protuberances with long and stiff hairs, and similar ones are also on 
the thoracal segments above. The silk cocoon is brown-haired; the pupa is about 26 mm long, reddish-black, 
and at both its ends rounded. 
4. Genus: Triclietra Ww. 
Body strong. Proboscis very short. Head and thorax with very long hair. Frons with long projecting 
hairs. Palpi very short and stronlgy haired like the legs, the hind tibiae exhibiting small terminal spurs. Wings 
rather narrow, costal margin of forewing slightly convex towards the apex; three lower veins, the first of which 
touches the second at the base; at the apex rounded, densely scaled and at the base hairy. In the <$ the 
antennae are long-combed and slightly longer than half the body; the abdomen projects a little beyond 
the anal angle and its end is covered with very long tufted hair. Antennae of $ slightly pectinate and not 
beyond half the length of the body, the abdomen projects a little beyond the anal angle, the end being densely 
woolly. 
T. sparshalli Curt. (58 c) (d'), described from England, but probably imported from Australia. The 
whole insect is creamy yellowish, with ochreous pectinations, the eyes surrounded by grey and black, prothorax 
light reddish-brown, anal tuft yellow, wings glossy with purple-tinted veins, anterior tibiae in front as well 
as the basal joint of the anterior tarsi dark brown, whilst all the tarsi below are ochreous. Expanse of wings: 
47 mm. 
T. fratema Btlr. The 9 differs from T. sparshalli only in the white anterior legs not being black above. 
In the 9 all the wings are white, thorax black, tegulae inside brownish-yellow, the large anal wool brown. 
Expanse of wings: <3 43, 9 53 mm. Moreton Bay in Australia. 
T. stibosoma Btlr. 9 distinguished from T. mesomelas by the abdomen being snow-white as in fratema 
and showing brown anal wool above. Expanse of wings: 53 mm. New-South Wales. 
T. mesomelas Wkr. (58 c). <d9 white, antennae brownish yellow, anterior legs above black, the body 
more or less black, in the $ the head is black, only in front white, the abdomen blackish and at both its ends 
whitish, whereas in the 9 the head and thorax are black and the abdomen above blackish and provided with 
black anal wool. Length of body 10—14, expanse of wings 33—45 mm. The species varies a great deal; the 
abdomen may be (9) at the apex ochreous (f. ochripyga form, nov.) or (9) towards the apex beneath black¬ 
haired (f. melanotricha form, nov.), or white, towards the apex black (f. bicolorifera form. nov.)\ in the latter 
form the head and the anterior portion of the thorax may be white (f. antealba form. nov.). Moreover the 
thorax may be brown and the apical tip covered with brownish yellow hair, the rest of the insect being white 
(f. tricolor form, nov.), and finally the thorax may be white-haired, but the rest of the insect as /. tricolor 
(f. albotestacea form. nov.). — Australia, Tasmania. 
5. Genus: Comana Wkr. 
It is questionable whether it belongs to this place. Walker described it as a Limacodida, whereas 
Kirby placed it to the Lymantriidae. Swiniioe, in a revision of the Lymantriidae of the British Museum, states 
that the genus resp. type lias now been removed from the Lymantriidae in the British Museum, but he could 
not discover it anymore and can therefore not say anything about its systematic position. And as the ,,Teara“ 
are now neither ranged anymore among the Lymantriidae in the British Museum, this statement by Swin-hoe 
does by no means exclude the conjecture that the genus Comana is closely allied with Teara as Kirby supposed 
it to be. Under these circumstances I must content myself with repeating Walker’s diagnoses. — 9 body 
smooth, very strong. Proboscis stunted. Palpi smooth, rather strong, obliquely rising, not reaching the vertex; 
the third joint conical, not more than x / 6 of the length of the second. Antennae smooth. Legs smooth and 
strong, hind tibiae with 4 moderately long spurs. Wings oblong. Forewing at the apex roundish, costa slightly 
convex, distal margin convex and very oblique, the second of the lower veins more remote from the third than 
from the first, the third about thrice as distant from the fourth as from the second, the second of the upper 
veins being forked. 
C. collaris Wkr. 9 white. Head ochreous round the eyes. Palpi ochreous. Antennae reddish-yellow. 
Thorax in front with a broad ochreous band. Legs above ochreous. Wings unicoloured. Length of body : 16, 
expanse of wings: 57 mm [it is doubtful whether these sizes are correct]. North Australia,
