354 REVISION OF AUSTRALIAN LEPIDOPTERA, 



Palpi fuscous. Antennae oehreous-brown. Thorax yellow, orange, brown, or 

 reddish; anteriorly with a broad, sharply defined, transverse band, fuscous mixed 

 with whitish. Abdomen and legs yellow, orange, brown, or reddish. Forewings 

 triangular, eosta straight to two-thirds, thence moderately arched, apex rounded- 

 rectangular, termen nearly straight or slightly sinuate, oblique; yellow, orange, 

 brown or reddish; a moderate, circular ocellus about middle, orange, edged an- 

 teriorly first with whitish, then with brown, edged posteriorly with fuscous, with 

 a central, fine, hyaline or thinly-scaled, transverse streak; a bi-oad costal streak 

 from base to about five-sixths, fuscous mixed with whitish; a fuscous line from 

 one-fifth costa, at first transverse, then sharply bent inwards and inwardly-curved 

 to one-fourth dorsum; an oblique fuscoud line from costa before apex to mid- 

 doli'sum, nearly straight, edged posteriorly with whitish irroration; cilia con- 

 colorous. Hindwings with termen rounded; colour and ocellus as forewings; a 

 transverse line at three-fourths parallel to termen. 



The c? varies in colour; it is most commonly yellow, but may be orange, 

 brown, or reddish; the ? is uniformly brown.

3. Anthehaea loranthi. 



Antheraea loranthi, Luc, Proc. Linn. Soc. N.S.W., 1891, p. 292. 



c?. 120-145 mm. ?. 150-155 mm. Head and palpi reddish or orange-red- 

 dish. Antennae brownisli. Thorax reddish or orange-reddish; anterior edge 

 broadly fuscous. Abdomen and legs reddish or orange-reddish. Forewings tri- 

 angular, costa straight to two-thirds, thence strongly arched, apex rounded, ter- 

 men more or less sinuate, oblique; reddish or orange-reddish; a moderate or 

 rather large, circular, discal ocellus slightly beyond middle; dark-red, edged an- 

 teriorly broadly with whitish, and then again with dark-red, edged' posteriorly 

 narrowly with whitish and then with blackish, a fine, transverse, central streak 

 hyaline or thinly-scaled; a broad, fuscous, costal streak from base to about five- 

 sixths; a blackish subcostal spot surrounded by whitish suffusion before apex, 

 from which proceeds a broadly suffused fuscous line to two-thirds dorsum; a 

 suffused rosy patch at apes; cilia eoncolorous. Hindwings with termen rounded; 

 colour and ocellus as forewings; a faintly-marked fuscous line at three-fourths 

 parallel to termen. 



N. Qland: Herberton, Townsville; Qland: Duaringa, Gayndah, Brisbane. 



The larvae feed gregariously on LorantM(s, usually high on Eucalyptus trees, 

 and pupate in a mass on the butt of the Loranthus. 



4. Antheraea exgaea, n.sp. 

 £770105, inland. 



6. 90 mm. S. 95-110 mm. Differs from A. loranthi as follows :— Size 

 much smaller; colour pale oehreous-yellow ; wings rather thinly scaled; thorax 

 not fuscous anteriorly; a broadly suffused fuscous band from beneath costa near 

 apex to termen, on which it is expanded to reach middle or before middle; a 

 broadly suffused post-median band on hindwing immediately beyond ocellus. 



This may be no more than an inland race of the preceding modified by arid 

 conditions; but I propose to regard it as distinct until intermediate forms have 

 been proved to occur. I am informed that this species also feeds on Loranthus, 

 but pupates singly, not in a mass.
