intense lines, the first of which extends from the first quarter of the costal margin to two fifths of the anal 
margin and is somewhat sinuate, whereas the second runs from about two thirds of the costal margin to beyond 
the middle of the anal margin and forms a minute distal tooth; a small, transverse-oval, before the centre brown 
discal spot encircled with black, and an indistinct, irregular, subterminal row of black spots. Hindwings whitish. 
Expanse of wings: £ 35, $ 50 mm. Australia. 
B. crenulata T. P. Lucas. <£$. Dark chocolate-coloured, in the $ the thorax is somewhat lighter, crenutata. 
Apex of palpus ferruginous reddish-brown. Antennae reddish-ochreous, pinnae of the $ very short. In the 
forewing the costal margin is almost straight, at the end the wing is rounded off; the margin almost straight, 
finely crenulated, the veins darker, at two fifths near the median longitudinal line there is a small black discal 
spot which is indistinct or entirely absent in the $, in the <$ a fine dark marginal line, which is in the $ 
ochreous between the crenulations, the fringes vary between ochreous and chocolate-brown. Hindwing in the 
dorsal area very hairy, fringes chocolate-coloured. Expanse of wings: <$ 34 to 38, $ 60 mm. Australia: Eltham, 
Melbourne, Brisbane. (It is presumably scarcely a genuine Bombyxl) 
2. Genus: Ectrocta Limps. 
A strikingly large and broad-winged Bombycid; both wings with an emarginatecl border (the forewing 
behind the apex and the hindwing at the anal angle). Palpi very small. In the forewing the veins 6 + 7 + 8 + 9 
+ 10 A 11 are forked, 6 rising between 10 and 11, 7 and 8 being very short and terminating right behind resp. 
right before the apex, 9 also being short and from 10 more than twice as distant as from 8; 3 and 4 from the 
same place (angle of the cell), diverging very much towards the margin. In the hindwing 5 rises from 
the centre of the discocedular, 6 and 7 being forked. 
E. diaphana Hmps. (57 g). Head, thorax and abdomen light ochreous-brown, shaded darker, diaphana. 
All the wings white, semi-diaphanous. Forewing with a dark basal spot, a subbasal dark curved band, a streak- 
shaped, dark discocellular spot, a doubly S-like curved dark submarginal line, and a large dark apical spot. 
Hindwing with an antemedian dark spot in the dorsal area, a post median band of dark spots and a slight ly 
darkened margin. Expanse of wings: 54 mm. Burma. 
3. Genus: Ocinara Wkr. 
This genus with which we unite Trilocha Moore, Ernolatia Wlcr., and Chazena Wkr., beside the genus 
Naprepa Wkr., being denominated by a name already conferred, has already been described in Vol. II, p. 191 
(as Ocinera). 
0. signifera Wkr. (= lactea Hutt.) (Vol. II, t. 35 f) being widely distributed in India and occurring signifera. 
besides in the Andamans, Sumatra and Borneo, has been described in Vol. II, p. 191. f. diaphana Mr. has no diaphana.

already been dealt with in Vol. II. p. 191, by the name of apicalis Wkr. ; the latter name, which is incomprehensibly 
also used by Hampson, is, however, of a later date than lida Moore and must therefore be mentioned as a 
synonym. It occurs in China, India, Java and Borneo. — Seitz (according to a letter) observed in Hongkong 
that Ocinara lida takes up a very peculiar position when at rest, standing on the centre of the leaf o n i ts 
head, keeping the wings spread on the leaf, the abdomen being erect and bent upside down. On beating 
the imago down, it closes its wings and bends the abdomen under its chest. 
0. varians Wkr. (= albicollis Wkr., cervina Wkr., velata Wkr.) (Vol. II, t. 35 f.) has been described varians. 
in Vol. II, p. 191, and occurs in India, Ceylon, China, Formosa, the Philippines, and Borneo.

areas of the forewing; the latter provided with reddish-brown, double ante-and postmedian lines only distinct 
in the dorsal area, as well as with a discocellular spot of the ground-colour of the wings. Hindwing light reddish- 
brown, anal margin light brown with darker markings. Beneath the forewing is chocolate with ochreous 
veins, the hindwing ochreous-brown with a chocolate shade at the margin, a black discocellular spot and two 
undulate brown postmedian transverse lines, the first of which is only distinct in the dorsal area. Exjianse 
of wings: 37 mm. Formosa: Rantaizan, 7500 ft., in May. It is reported to occur also in India. 
This original description was drawn up according to a specimen that was somewhat rubbed off on 
the forewing. From the German Entomological Museum there are two before me with an expanse of wings 
of only 30 to 31 mm, the length of the forewing being 14 to 15, and the length of the body 15 to 16 mm. Both 
wings exhibit a faint violettish hue, and the chocolate-brown colouring is more or less removed by extremely
