24 AUSTEALIAN LEPIDOPTEEA 



The whole surface above is silky jet black— about the middle of the upper wing is a broad transverse pure white band, 

 slightly dentate on the outer margin and having a small black oar-shaped mark at the end of the discoidal cell ; there are also a 

 few faint whitish subcostal streaks, and, towards the anal angle of lower wing, an indistinct whitish spot ; margins of both wings 

 scalloped with white ; head and neck bright tawny-orange ; thorax black with tawny hairs ; abdomen black, in male tufted with 

 orange at the tail. Underside bronzy-brown, with white margins. Legs with the femora densely tufted with orange coloured hairs. 



The caterpillar on Breynia ohlongifolia, and the moth, are figured in the illustration.

 Catocala fusca, Scott, MS. 



This is a rare species, as during many years spent in collecting Lepidoptera at Ash Island, we only found a couple of the 

 larvae, which were feeding in company with the preceding species, Ophiusa (/Jfrontinus, in March, on the Breynia ohlongifolia. Like 

 the O.frontinus, the caterpillar rests with the body extended at full length, close to the branch ; but it differs greatly from that 

 species in appearance and conformation, being subdued in colouring and having all the feet present, although the pairs on the sixth 

 segment are considerably smaller than the others ; there are also two small pointed yellowish protuberances on the eleventh 

 segment. When full grown it measures 2 inches, is elongated, rather flat beneath, and attenuates very slightly towards the head ; 

 the colour throughout light pinkish-brown finely sprinkled with black, becoming rather darker on the back ; on the side of the 

 fourth segment is a yellowish spot, shaded with dark brown outside, and with a brown centre ; the spiracles and a few spots over 

 the legs are also brown ; head, thoracic and caudal feet, pale yellow with brown markings ; prologs pinkish-brown, spotted with 

 black. 



About the middle of April the caterpillars connected together some leaves of their food plant, by coarse silken threads, and 

 formed inside of these a strong silken cocoon, sufficiently large to hold the chrysalis, which measured 1 inch (fig. 1). The 

 chrysalis is dark plum colour, thickly coated with whitish bloom, rather stout in form, and blunt at the head. 



In August the moths took wing ; they measured about 2.^ inches in expanse, both being females. 



The Antennm setaceous, covered above with scales, below slightly pubescent, and with a lateral row of minute setae 



(fig. 2). 



The Labial palpi second joint half as long again as either basal or terminal, which are nearly equal ; basal and second joints 

 thickly covered with feathery scales, terminal only moderately covered, and rather obtuse at apex ; the 

 whole project forwards and upwards not quite even with the top of the eyes (fig. 3). 



The Legs: anterior pair rather small ; intermediate pair with two (fig. 4), and posterior pair with four, strong spurs 



on tibite ; tibise of all thickly clothed with feathery scales ; tarsi with small scales, and rows of small seta3 

 beneath. 



Wings decumbent in repose ; moth nocturnal. 



The entire upper surface of the moth is dusky brown, shaded and speckled with darker, having on the middle of upper 

 wing a broad transverse chocolate-brown bar bordered by a narrow ochreous-yellow line : this bar is deeply sinuated on the 

 outer margin, and here connects with a somewhat triangular patch of dark brown, also edged with ochreous-yellow, which 

 " proceeds from the apex of the wing ; near the base are two wavy transverse ochreous lines. The nervules across the disc of lower 

 wing are ochreous, and close to the margin near anal angle is a dusky triangular patch shaded outwardly with dark brown ; 

 margins dusky : head, thorax, and abdomen dusky brown, the thorax crested with dark brown hairs. Underside uniform dusky 

 brown. 



The Breynia ohlongifolia is again figured, with larva and female moth.
