Habitat. — Head of South- Western River, Kangaroo Island. 

 S.A. Museum. 



A single female was captured by me at the end of February, 

 1886, although several more were seen. The habit of the species 

 of this genus is entirely diurnal. They hunt solitarily, ascending 

 tall bushes and small trees, where they form conspicuous objects 

 when perched on slender dry twigs, and are visible from consider- 

 able distances. When approached, however, they let themselves 

 drop suddenly to the ground and are lost to sight, partly on 

 account of the close agreement of their colouring with that of 

 the ground, and partly through their great nimbleness, which 

 permits them to elude all pursuit usually. They appear to possess 

 no odour. In tlie specimen of this species the left one of the 

 cerci is only about half as long as the right, although otherwise 

 perfect. 



POLYZOSTERIA PUBESCENS, SpeC. 7101'.

 wrinkled, with larger, low, obtuse ridges and tubercles, forming 

 three indistinct rows on each side, besides other rugosities, 

 especially on the thoracic segments, and the whole covered more 

 or less by a dense pubescence of short whitish hairs. Head dark 

 greyish iridescent, punctate, with some yellowish lines or other 

 markings ; ocelliform spots indistinctly green or ];)ronze. IMouth
