BRONCHELIA. 2I5 



having been previously used by Herrich-Schaffer for another 

 genus of Geometne. Several sections are comprised under 

 this genus, which are separated by some authors. I have 

 figured the underside of one of the commonest and most 

 beautiful of the Australian species, which considerably re- 

 sembles Mr. Moore's genus Fingasa, under which I place it 

 provisionally.

This Moth is a native of Australia and Tasmania. It 

 expands about an inch and three-quarters. 



The wings are dentated, ashy- grey, finely dusted with black, 

 with the usual Hnes well marked, slender, black, and strongly 

 dentated, the sub-marginal line forming a large tooth. There 

 is a black dash at the end of the cell on all the wings. The 

 under side is pure white, with a blood-red line before the hind- 

 margin, which is entire and angulated on the hind-wings, but, 

 on the fore-wings, is reduced to two spots bordered with white 

 behind, with the marginal area blackish.

and are among the largest of the family, though not unlike our
