(length one and five- eighth inches) and a narrow parchment-like 

 strip of the posterior wings are green, except where the latter 

 are covered by the former, where a fine pink line marks the 

 upper surface of the one and the lower of the other. The 

 covered portions of the large anterior wings are transparent 

 and colourless. 



Some 20 years ago this species was rather numerous near 

 Lyndoch, but for many years few have been noticed. Two 

 other smaller species were obtained at Ardrossan. The larger 

 one is of the same form of body as the preceding and also 

 coloured green, but the covered portions of the wings are 

 bright yellow, and the nervures of the remaining parts of the 

 posterior wings are of a rich rose colour crossed by numerous 

 narrow, concentric bands of the same tint. The smaller Phasma 

 has a thin elongated body (like a straw) three and five-eighth 

 inches in length and of a reddish brown colour. The transparent 

 posterior wings are tinted along the radiating nervures with 

 many black spots, at almost regular intervals, leaving tran- 

 sparent concentric bands between them. Only one specimen 

 of either was obtained. 



Order Hemiptera. 

 The Hemiptera, forming two groups, viz., Heteroptera and 

 Homoptera, are quite as well represented in South Australia 

 as any of the other orders, the Heteroptera, or bugs, being 

 represented by 164 and the Homoptera or Cicades by 108 species. 

 The first family of the former, the PENTATOMiDiE, comprise the 

 genera Scutellaria with three, and Tetyra with four species, 

 which have their scutellum so enlarged that it covers the whole 

 of the abdomen, and acts as a cover for their wings. These, as 

 most other bugs, are plant-feeders, and some species are very
