Hab. Percy Island, No. 2, north-east coast of Australia ; found 

 under stones (coll. Brazier). 



This charming species approaches near to Liotia speciosa, Angas, 

 from Port Jackson. I obtained six specimens during a stay of two 

 hours only at the Percy Islands.

[Eeceived November 24, 1874.] 

 Genus Cosmoscarta, Stal. 



COSMOSCARTA DISTANTI, n. Sp. 



Allied to C. bivittata and C. feralis, but in structure agreeing 

 better with C. xanthorliina. Head and thorax black, rather dull ; 

 scutellum black, pitchy at the margins ; abdomen above shining 

 purplish black ; body below black ; legs piceous ; tegmina black, 

 becoming piceous towards apex, crossed by two orange bands, the 

 inner one somewhat broad, crossing centre of clavus, and widest in 

 the centre, the outer one only half as wide, widest and angulated in 

 the middle externally; wings smoky brown. Length 18 millims. ; 

 exp. tegm. 49.
