Heliocausta complanula, Turn. : I.e. 



Antennal ciliations in male 3. Forewings narrower than 

 in acmaea, and hind wings not ochreous tinged. 



Hab. — Queensland: Brisbane, Stanthorpe, in February; 

 three male examples. 



Heliocausta simplex, Turn. : I.e., p. 5. 



Heliocausta plausibilis, Meyr. : Exot. Micro., i., p. 128 (1913). 



Antennal ciliations in male 1\. The colour of forewings 

 from ochreous-grev to rosy ochreous-grey, but the rosy colour- 

 ation ma}?- be completely absent even from costal edge. 



Hab. — Queensland: Brisbane, in September and October; 

 Mount Tambourine, in October; New South Wales: Glen 

 Innes, in October ; Victoria : Geelong ; Gisborne, in December. 



Heliocausta phanozona, Turn.: ante, 1896, p. 5. 



d , 9 ; 13-18 mm. Antennal ciliations in male 1. 

 Hab. — Queensland: Brisbane, in August, January, and 

 April ; four specimens. 



Heliocausta ijhodopleura. 



Philobota rhocloplcura , Turn. : I.e., 1898, p. 208. 



(5,0; 18-24 mm. Antennal ciliations in male 1. This 

 species certainly has the antennal pecten better developed 

 than in other species of Heliocausta, but its natural affinities 

 are with them and not with Philobota. A good structural 

 point is the origin of vein 5 of the hindwing, which is bent 

 so as to be approximated to 4 . 



Its nearest ally is sobriella, Wlk., which has also usually 

 a fairly-developed pecten and vein 7 of forewings ending in 

 termen, and should be equally referred to Heliocausta , unless, 

 indeed, a new genus be established for this and a few allied 

 species. 



Hab. — Queensland: Brisbane, in October and December; 

 Stradbroke Island, in October and December : Mount Tam- 

 bourine, in November; New South Wales: Emmaville, near 

 Glen Innes. 



Heliocausta pelosticta, Meyr. : Proc. Linn. Soc. 

 N.S. Wales, 1882, p. 473. 



Antennal ciliations in male 2^. In the female the whole 

 of disc, except a narrow area at base of costa and another on 

 ^anterior margin of terminal band, is suffused with purple- 

 fuscous, so that the two sexes are very distinct in appearance. 



Hab. — Queensland: Brisbane, Coolangatta ; New South 

 Wales: Murrurundi.
