Ilab. — Tasmania (on Eucalyptus sp. ; A. M. Lea); Victoria 

 (on E. sp.; C. French, Jr.); New South Wales, widely distributed 

 (on E. sp., &c. ; W. W. Froggatt); Townsville, Queensland (on 

 E. sp.; H. Tryon). 



This species is our commonest " sugar-lerp " which has a very 

 wide range over eastern Australia It does not confine its 

 attention to one species of Eucalypt, but is found upon E capi- 

 tellata, E. piperita, E. leucoxylon, E. gracilis, and several other 

 species. 



As children we used to gather and eat the scales of tins species, 

 but it is those of the larger species that were collected and eaten 

 by the natives in the Mallee scrubs, and which were described as 

 " manna." In the venation of the wings this species could come 

 under the genus Aphalara, but Schwarz has examined some 

 specimens of this species and redefined Signoret's genus Spondy- 

 liaspis for its reception on account of the peculiar spiny 

 structure of the hind legs, differences that have not been used 

 very much as generic characters in this group of the Homoptera. 

 Signoret defined the genus upon the lerp-scales only, and had 

 never seen the perfect insects.
