HAB. Queensland. Cairns and Kuranda, (Koebele 2250) The 

 larvae were observed in abundance around Cairns by Messrs. 

 Koebele and Perkins, and were found to be feeding upon larvae 

 and nymphs of Poecilopterine Fulgorids of the genus Sipliaiita. 

 Many of the puparia were observed to be parasitized by a 

 Chalcid. On one occasion great numbers of the adults were 

 seen in one locality, hovering at a considerable height above the 

 ground. 



The following is a brief description of the puparium : Pyriform 

 bulbous anteriorly, attenuated posteriorly, coriaceous, at the 

 l)Osterior extremity a resjMratory tub>e. about one-fifth of the 

 length of the puparium .with a very short apical bifurcation, up- 

 on which opens the paired stigmata. General coloration dirty 

 brown and blackish, with pale ill-defined bands arising in pairs 

 from the median dorsal area. Length, 5 mm. length of tube r 

 mm. Respiratory tube testaceous.
