Studies in Australian Lepidoptera. 29* 



N.S.W., Bulli, in March; three specimens received from Mr. G- 

 H, Hardy, who has presented the type to the Queensland Museum. 



EUCHKOMIA POLYMENA. 



N.W.A., Wyndham; two specimens received from Mr. L. J. New- 

 man. Previously the only Australian record for this wide-ranging: 

 species was a single specimen in the Macleay Museum, said to be from 

 North Australia. 



Fam. ARCTIADAE. 



Hestiarcha atala, n. sp. 



^ 30 mm. Head ochreous. Palpi short (about 1), porrect or^ 

 somewhat drooping; ochreous, slightly fuscous-tinged. Antennae 

 (broken short) ochreous; in S" simple, shortly ciliated (1). Thorax- 

 brownish-ochreous. Abdomen with apical half densely hairy on dor- 

 sum and sides; brownish-ochreous; beneath ochreous. Legs ochreous; 

 anterior pair suffused with fuscous. Forewings elongate, posteriorly 

 dilated, costa very slightly arched, apex rounded, termen scarcely 

 oblique, rounded towards tornus; brownish-ochreous; cilia brownish- 

 ochreous. Hindwings twice as broad as forewings, termen rounded; 

 p'ale-ochreous ; cilia pale-ochreous. 



2 Wings small, aborted, forewings when closed reaching nearly 

 or quite as far as apex of abdomen. 



In the (^ the tongue is present but weakly developed. It differs- 

 from Hestiarcha pyrrhopa, Meyr., in the antennae not being pectinate, 

 and vein 6 of forewings arising separately, not stalked with 7, 8; 

 for I agree with Hampson that vein 9 is absent, not 6 as in Meyrick's 

 diagnosis. Otherwise the peculiar neuration of both species is iden- 

 tical, except that in atala, the discocellulars of the hindwing, though 

 weak are traceable, the cell being very short (about i). As these 

 two forms agree in so many features, and must be allied, it would 

 be unwise to separate them into two genera. The 2 of vyrrhopa is 

 unknown. 



T., Mt. Wellington, in January and February; four examples 

 (1. J^ 3 $ ), all found at rest under stones by Mr. G. H. Hardy. One 

 $ had emerged from a slight cocoon of silk and hairs. The types 

 have been presented to the Queensland Museum. 



Heliosia aedumena, n. sp. 



(^ 16-20 mm. Head brown- whitish ; face and palpi ochreous- 

 whitish. Antennae brown-whitish; in S' serrate, shortly ciliated 

 (1/3), with longer bristles (1). Thorax and abdomen brown- whitish. 

 Legs ochreous- whitish. Forewings elongate, costa rather strongly 

 arched, apex round-pointed, termen obliquely rounded; brown- 

 whitish; markings fuscous; median discal dots at 1/3 and 2/3; some- 

 times a suffused dorsal spot at 1/3; a faint outwardly-curved line- 

 from I costa to 2/3 dorsum; some suffusion on tornus and before-
