■ Maskell says : " This insect in the general peg-top shape of the adult 

 female resembles E. hoherifp iMask, a New Zealand species, which also con- 

 structs similar sacs on the bark of its food-plant. The Australian species 

 differs in the character of the s])ines, in having only two anal tubei'cles and 

 in not having the feet atro])hied in the adult stage."
