before middle ; a tuf t of raised scales beneath costa near base ; 

 two black dots obliquely placed in disc close to base ; four or five 

 tufts of raised scales in disc between one-fourth and middle, each 

 preceded by a black or dai'k fuscous dot ; two raised tufts trans- 

 versely placed in disc beyond middle, preceded by cloudy 

 blackish dots ; a cloudy interrupted angulated blackish line from 

 three-fourths of costa to anal angle ; a sharply denned black line 

 along hindmargin, tending to be interrupted on the veins : cilia 

 whitish, with two broad indistinct grey lines. Hindwings 

 whitish-grey or pale grey ; cilia grey-whitish. 



Two specimens, taken at Sydney and Melbourne respectively,

4. CoSCINOPTYCHA n. (J. 



Thorax smooth. Antennoe of male much thickened, dentate, 

 strongly ciliated, basal joint swollen, of female slender, simple. 

 Palpi moderate, porrectecl, second joint roughly haired above 

 and below towards apex, terminal joint in male concealed, in 

 female exposed. Posterior tibico smooth above. Forewiugs 

 elongate, narrow, costa in male simple, nearly straight, bent 

 before apex, hindmargin oblique ; surface with tufts of raised 

 scales, and in male with a membranous longitudinal ridge 

 towards base. Hindwings broader than forewings, apex 

 elongate, almost acute. Forewings with veins 7 and 8 separate, 

 vein 7 running to hindmargin, secondary cell absent, upper basal 

 fork of vein 1 obsolete. Hindwings with 6 veins, 3 and 4 in 

 male from a point or short-stalked, in female long-stalked from 

 posterior angle of cell, 5 from upper angle of cell to apex, 6 

 free. 



This peculiar genus is well defined by the curious swollen 

 bladder-like ridge on the forewings of male, the strongly dentate 

 and ciliated antenna) of male, the rather short palpi, and the 

 smooth posterior tibia? ; it is very abnormal in appearance.
