BRONCHELIA. 215 



having been previously used by Herrich-Schaffer for another 

 genus of Geometry. 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 Pingasa, under which I place it 

 provisionally. 



PINGASA OCCULTARIA. 



(Plate CXLVL, Fig. 6.) 



Phalczna occultaria^ Donovan, Ins. New Holland, pi. 36, 



fig. 4 (1805). 

 Boarmia occultaria^ Boisduval, Voy. Astrolabe, Lepid. p. 257, 



no. i (1832). 



Hypochroma occultaria^ Guene'e, Spec. Ge'n. Lepid. Uran. et 

 Phal. i. p. 281 (1857). 



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 lines 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.

The species included in this genus are all Tropical American, 

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