^ Hysterosia aureoalbida, sp. n. 



Antennce, ^, white above, greyish beneath. Palpi and Head 

 white. Thorax very pale golden yellow. Forewings, <, shining 

 silvery white, with a very pale golden yellow suffusion which is 

 divided into oblique transverse bands beyond the middle ; three or 

 more coppery-red spots, one beneath the fold at one-third from 

 the base, consisting of only a few scattered scales above the dorsal 

 margin, near the outer end of the fold partially connected by a 

 line of scales with a more conspicuous spot at the upper angle of 

 the cell, a smaller spot lying half-way between this and the apex ; 

 these spots are all ill-defined (in some specimens consisting merely 

 of groups of coppery-red scales, and in some almost entirely 

 disappearing) ; cilia white, with a slight golden tinge. Exp. al., $ 

 17 mm. Hindwings whitish, tinged with lilac-grey ; cilia shining 

 white. Abdomen greyish. 



The $ is very different in colour from the ^, the general 

 effect is pale fawn-ochreous, the shining whitish ground show- 

 ing only between the scattered patches of this colour and 

 in transverse oblique bands across the apical portion of the 

 wing. Exp. aZ., $ 16 mm. The palpi, which are very sharp in 

 the $ , are somewhat shorter and more obtuse in the 9 , and 

 together with the head, thorax, and antennae, are pale fawn- 

 ochreous. The hindwings are also a little darker.
