334 Mr. E. Meyrick on the classification 



middle, thence rectangularly bent and running to middle of inner 

 margin, lower half of band suffused with ground colour except on 

 inner edge ; cilia ochreous-yellow, ti^JS paler. 



A very elegant species, variable in size. 



Quorn and Petersburg, South Australia ; common in 

 October, appearing to frequent Docloncea lohulata. 



Metallarcha eurychrysa, n. s. 

 (?, 22 mm. Head, palpi, antennae, thorax, abdomen, and legs 

 light ochreous-yellow ; palpi somewhat mixed with dark fuscous 

 above ; antennae spotted with dark fuscous ; shoulders and a small 

 central spot of thorax dark fuscous ; anterior legs suffused with 

 dark fuscous. Fore wings moderate, triangular, costa faintly 

 sinuate, somewhat arched posteriorly, apex tolerably rounded, hind 

 margin obliquely rounded ; jpale yellow ; markings dark fuscous ; 

 a rather narrow streak along costa throughout, attenuated to a fine 

 line posteriorly ; a somewhat bent narrow fascia at one-third, 

 dilated on costa ; a broader fascia from two-thirds of costa to 

 before anal angle, twice slightly sinuate ; a rather narrow hind- 

 marginal band, attenuated to a point at anal angle, anterior edge 

 dentate, posterior marked with small triangular ochreous-yellow 

 spots ; cilia pale yellow, tips greenish. Hind wings pale ochreous- 

 yellow ; a fuscous-grey attenuated streak from costa at three- 

 fourths to hind margin below middle, thence abruptly bent and 

 continued very obscurely and almost obsoletely to middle of inner 

 margin ; cilia pale ochreous-yellow. 



The hind-marginal band of the hind wings is only 

 visible on its anterior edge. 



Ardrossan, South Australia ; February and April ; a 

 specimen received from the Adelaide Museum, which 

 possesses a second. 



Metallarcha achoealis, Walk. 



Botys achoealis (achoeusalis) , Walk., 1007. 



I have not obtained this species for description. The 

 markings of the fore wings are much as in M. eurychrysa, 

 but the pale yellow is replaced by deep orange ; the hind 

 wings are deep orange, with a dark fuscous hind-mar- 

 ginal band. Although I have not examined the structure, 

 the species is probably referable here, and is conspicu- 

 ously distinct. 



Several specimens from Eastern Australia in the 

 British Museum.
