866 REVISION OF AUSTRALIAN LEPIDOPTERA, 



belongs to this species or not, I cannot determine ; at first sight 

 it certainly looks distinct ; I have five specimens, all from Sydney 

 and quite similar, but except in the general dark suff'usion there 

 seems no tangible point of separation ; I have no ^ of this form, 

 and its discovery may show that it is structurally distinct, and a 

 good species : meanwhile, I prefer to regard it as a varietal form. 

 The fact that I have taken no $, in a locality which I worked so 

 long, is in favour of this view. 



79. Xanth. vacuaria, Gn. 



(Coremia vacuaria, Gn. X, 418.) 



(J. 28 mm. Head, palpi, and thoi-ax p'ale reddish-ochreous, 

 mixed with dark fuscous ; palpi 2. Antennae fuscous, pecti- 

 nations very short (1), terminating in fascicles of cilia (2), apical 

 I simple. Forewings triangular, hindmargin rather waved, slightly 

 bowed, oblique ; pale ochreous, with cloudy reddish-ochreous 

 waved transverse lines ; basal patch marked with blackish lines, 

 outer edge rather curved, with a few whitish scales ; median band 

 dark grey, marked with blackish lines, anterior margin from | of 

 costa to I of inner margin, rather irregularly cui'ved, posterior 

 margin from f of costa to § of inner margin, edged by a fine 

 whitish line, curved near costa, median third forming a moderate 

 triangular round-pointed projection ; a black median discal dot ; 

 subterminal line faintly whitish, waved ; an interrupted black 

 hindmarginal line : cilia whitish-ochreous suffused with pale rosy, 

 with two obscure grey lines, ban-ed with darker (partly imper- 

 fect). Hindwings with hindmargin waved, rounded ; pale 

 ochreous, on basal third sprinkled with grey ; a median band of 

 four grey lines, posterior angulated in middle ; a blackish hind- 

 marginal line ; cilia pale ochreous, mixed with whitish and grey. 



Hobart, Tasmania ; Mount Lofty, South Australia ; two 

 specimens received from Mr. E. L. Guest. The short antennal 

 pectinations are easily overlooked, as they were by Guenee, 

 though his mention of the fasciculated ciliations proves that he 

 had certainly this species before him, and not a Hydriomena ; 

 his description is also clear and good.
