whole, fourth very small ; tegmina as long or longer than the 

 wings; the latter rudimentary, anterior part pale brown with 

 a few irregular narrow black bars; posterior part black, 

 translucent. Length of body, about 5| in.; head, about | in.' 

 forelegs, about 3f in. ; middle pair, about 2f in. ; tegmina, about 

 f in.; wings, about f in.; foliolets, about f in. The above 

 refers to the female, the male being slightly smaller. In the 

 nymphal form the colour is greenish, but the dentation of the 

 legs, notably the teeth on the upper edge, quite identical with 

 those of the perfect form in all my specimens. The size is also 

 less — from 3f to 4f in.., and the body more slender. 



The eggs are elliptic, cylindrical, about one-eighth inch long 

 and half as thick, wrinkled, greyish black when mature, and 

 open with a lid at one end, which bears a conspicuous round 

 knob. 



They live upon stringybark shrubs in the Mount Lofty 

 Ranges.
