1016 ON A NEW PIELUS FROM THE BLUE MOUNTAINS. 



Ill the simple pectinate structure of the antennae and in all 

 other essential characters this species agrees with Pielus hya- 

 hnatm, Herr. Sch., but its brilliant colour and conspicuous mark- 

 ings will distinguish it at once from all the known members of 

 the genus. 



A female specimen,* measuring 182 mm., obtained at Katoomba, 

 about eight miles from Lawson, in February, 1884, is probablv 

 the female of the form described above ; it is without markings 

 and is of a tawny brownish red colour, faintly tinged with pur- 

 plish on the abdomen and at the bases of the hind wings. 



Both the $ and ? specimens were collected by Mr. Prince.
