Type in Coll. Meyrick. 



Q., Brisbane; N.S.W., Sydney. 



Genus 16. Hydpiomena. 



Hydriomena, Hb. Verz., p. 322. 



Face with more or less projecting or loose scales, or with 

 conical tuft. Palpi moderate, porrected, or sub-ascending, rough- 

 scaled. Antennae in c? ciliated, rarely dentate or naked. 

 Thorax often crested, glabrous beneath. Abdomen not crested, 

 or with crests on two basal segments only. Posterior tibiae with 

 all spurs present. Fore wings with areole double. Hind wings 

 with 8 anastomosing with cell from near base to beyond middle 

 (Meyrick). 



This genus may be divided into two or three sections according 

 to the neuration of tlie hind wings, two at least of which should, 

 I think, be considered distinct genera. The overwhelming 

 majority of the Australian species belong to the idrst section, but 

 in a small British collection which I have examined, the majority 

 belong to the second section. The genus is exclusively temperate, 

 only live or six species being known at present to range as far as 

 Southern Queensland. In Tasmania, Victoria, and the moun- 

 tainous pjirts of New South Wales, the species are numerous, 

 and no doubt many more will be discovered. For my material I 

 am mostly indebted to Mr. G. Lyell. 



As the additions to this genus are comparatively small, I shall 

 not repeat Mr. Meyrick's tabulation (P.L.S. N.S.W., 1890, p. 

 820), but shall content myself witii indicating the affinities of 

 the new species.

 57. Hydriomena phaedra. 



Hydriomena phaedra, Meyr. P.L.S. N.S.W., 1890, p. 824. 



This species is very variable in the coloration of the median 

 band of fore wings, which sometimes contains a complete, or 

 interrupted, snow-white fascia; sometimes this fascia is sufi'used 

 with pale fuscous, and sometimes it is dilated so as to occupy 

 most of the median band.
