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 Siphanfa. 

 jN'fany 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 

 posterior extremity a respiratory tube, 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. Leiigth, 5 mm. length of tube i 

 mm. Respiratory tube testaceous. 



Baccha uioiiobia, sp. nov. 



Male : This species closely resembles the preceeding ; the chief 

 difference being that of color. Antennal prominence more pro- 

 nounced than in the male of B. siphaiiticida, with a similar, but 

 more vivid purplish-violet patch than that of the female of that 

 species; antennae, dark orange. Thorax and scutellum, purplish- 

 aeneous, with golden reflection anteriorly, clothed with short 

 brownish hairs, scutellum fringed with dark hairs ; sides of pro- 

 notum, the meso-and sternopleuron golden aeneous, with orange 

 pubescence and hairs, pteropleuron brilliant golden with pur- 

 plish marginal reflection. Abdomen, three times the length 

 of the thorax, purplish-black, without markings, with whitish 

 hairs, very long on the sides at base. Wings infuscate, irides- 

 cent, with still darker infuscation distributed as in the female of 

 B. sipJiaiiticida.. Alulae large. Legs, brownish, coxae and 

 trochanters blackish, hind femora and tibiae darkly infuscate,
