458 DESCRIPTIONS OF AUSTRALIAN MICRO -LEPIDOPTERA, 



12. ACROCETJTHES, n. g. 



Thorax smooth or crested. Antennae short, in male thickened, 

 ciliated. Palpi moderate, straight, porrected, in male clothed 

 above with very long dense erect spreading hairs, in female 

 with dense rather appressed scales, terminal joint almost concealed. 

 Abdomen in male with very large tufted anal valves. Forewings 

 short, broadly oblong, costa in male with a short imperfect basal 

 fold, arched before middle, apex nearly rectangular, hindmargin 

 obliquely rounded. Hindwings rounded, elongate, hardly as 

 broad as forewings. Forewings with veins 7 and 8 stalked, vein 

 7 running to hindmargin. Hindwings with veins 3 and 4 from 

 a point, 5 approximated to 4 at base, 6 and 7 stalked. 



Distinguished from its nearest allies by the imperfect costal 

 fold, the erect spreading tuft of hairs on the upper side of the 

 palpi, and the large tufted abdominal valves of the male ; the 

 female is hardly distinguishable from Capua. I have included A. 

 oxygrammana in the genus on account of the evident close alliance 

 between the female and the corresponding sex of A. metaxantliana; 

 but the male is still unknown to me. 



A. metaxantliana may be known from A. oxygrammana by the 

 pale yellow hindwings.
