20 AUSTRALIAN LEPIDOPTEKA 



Tlic Legs, in both sexes slightly hairy, with brushes of long hair exteriorly on tibioc and each joint of the tarsi ; 



2n(l pairs with 2, and posterior pairs (fig. 5, male) with 4 small spurs on tibia;. 



At rest the wings are detlexed ; the male carrying the head and shoulders erect. 



The superior wings of the male above are pale oehrcous, with a very large broad dark brown patch from the base to a httle 

 beyond the middle, leaving however a fulvous discal spot, and irregularly bifurcate over the hinder angle ; beyond this is an 

 undulating transverse brown line, parallel to the exterior margin which is ornamented by a row of dark dots. The under wings 

 are of a pale shining oehrcous colour, the exterior margin only with black dots. The head, coUar, and abdomen black, the latter 

 tipped with white ; the thorax and adjoining segment bright oehrcous, and the antenna; brown. The upper surface of the female 

 accords with the description just given, but is much paler with a silvery hue on the upper wings and thorax. 



The underneath of both sexes is dull pale brown margined by white. 



We may add that the wavy ridges on the superior -ndngs of the Uoratiophora; are wanting in this species ; again appearing, 

 although slightly, in the following. 



The present delineation consists of two caterpillars, the male moth, the cocoon, and the Xyloinclum pyriforme in flower. 



SPECIES 2.— APODA INFBEQUBNS.— (Plate VI.) 



In January we found a single specimen of this caterpillar feeding upon the young leaves of the Scolopia Brownii, and 

 many years elapsed before we again met with the species, which we then procured in abundance, existing upon the Podocarpus 

 spinulosus and EUcodendron Australe. It was during this long interval that we bestowed upon them the inappropriate name 

 of " infrequens." 



In shape the larva is onisciform, and in colour a rich velvety green ; the whole body covered by minute raised points 

 which under the microscope develop into conical tubercles, each emitting two fine seta;. Three delicate but darker coloured 

 longitudinal lines, the central one dorsal, complete the description of this caterpillar, which is in length 1:^ inch. 



The cocoon with a neat lid at the lower end, is attached to the tree, of a light fawn colour and generally ovate in form, 

 but this is greatly modified by the situation in which it is constructed, for instance in the crevices of the bark the shape will 

 adapt itself to all the inequalities. 



The chrysalis (fig. 1) is short, stout, i inch in length, and pale yellow in colour. 



The female moth measures in expanse of wings IJ inch, the male \ inch less. 



The Antennic, ...male moderately bipectinatcd to rather more than half the length, thence minutely serrated to the tips; 

 female (fig. 2) setaceous. 



The Labial palpi, (fig. 3, female, 4 and 5 male) small and pilose, projecting forward to nearly the front of the head ; 

 terminal joint small, pointed, slightly longer than the basal, middle joint nearly three times the length. 



The Legs, covered slightly with hair which becomes long and bushy in front of the tibia; and each joint of the 



tarsi ; 2nd pair (fig. 6) and posterior pairs with 2 small apical spurs on tibise. 



In repose the wings are dellcxed. 



The upper wings of the male are silvery fawn colour, with a very oblique undulating line of white edged interiorly with 

 dark brown and proceeding from a black discal spot to the inner margin ; within this line along the eosta to the base is also 

 white ; beyond it are delicate wavy transverse lines caused by slight corrugations. The under wings and thorax are fawn colour, 

 the former darkening outwardly, and the latter with whitish tippets. Head, antenna', and abdomen yellowish, the last banded 

 with brown and terminated by a brownish tuft. 



The female silvery fawn colour ; upper wings with a straightish pale hand, proceeding obliquely from a little beyond the 

 middle of the costa to nearly the base of the inner margin ; the exterior margin towards the tips, and the basal portion of the 

 \vings whitish, and indistinct raised wavy bands over the whole surface. Head antenna; and thorax fulvous ; abdomen pale 

 saturnine-red, faintly banded with brown. 



Beneath, both sexes are throughout dull fawn colour. 



The two moths, male and female, two caterpillars, the cocoon and a small twig of the Scolopia Brownii are given as 

 illustrations of this species and its habits.
