(S , 28 mm. Head, face, thorax, and abdomen blackish- 

 fuscous, antennae dark-orange, pectinations dark-orange, at 

 greatest length 6. Legs dark-fuscous. Forewings elongate- 

 triangular, costa straight, apex rounded, termen obliquely 

 rounded; hyaline-opalescent; veins outlined with pale ochreous> 

 costa broadly pale yellow, from base to near J, caused by con- 

 fluence of veins; cilia ochreous. Hindwings rather small, ter- 

 men rounded ; colour, veins, and cilia as in forewings ; costa 

 with a broad black line from base to middle, hairs of dorsum 

 black, moderately thick. 



Ct^se. — 40-45 mm. in length; diameter, 13 to 15 mm.; cir- 

 cumference, 30 mm. ; extreme circumference, 54 mm. ; ovate- 

 lanceolate, broadly tapering at both ends ; dull grey-whitish or 

 greyish-fuscous, thickly ornamented except jDOsterior J with (A) 

 innumerable, irregularly arranged fine long twigs of PinuH 

 insignis, which hang down loosely and vary in length from 10 

 to 40 mm. (B.) ornamented with similar tw^igs and pieces of 

 leaves or phyllodia of Eucalyptus. (C) ornamented throughout 

 with moderately large pieces of leaves or phyllodia of Eucaij/'p- 

 tus and Leptospermum, placed indiscriminately. The opening 

 of the lower extremity of the cocoon is broadly ovate. The case 

 is fixed to the food-plant by a thick piece of strong, silken 

 material which is generally looped to the stem, but is some- 

 times without the loop. The cases are very different in their 

 outward appearance on account of the different food-plants. 



Larva. — The larvae are similar to the previous species, but 

 somewhat lighter-coloured, and marked with reddish on anal 

 segments. 



This species is easily separated from nigrescens, Dbld., by 

 its orange antennae.

 Sydney, etc.. New South Wales; and Brisbane, Queensland.
