A frreat deal of doubt seems to exist in the minds of all desciibers of tlic 

 mealy bugs as to h(>\v this genus can be defined, and the latest writer, Cockerell. 

 has contributed a paper to the " Entomologist "" (vol. xxxv, p. 311', 1902), 

 in which he seems to leave the matter in still greater confusion. 



The generic name Moti.ophIehu.s was used by Leach without defining it, 

 and until Burmeister used it in his handbook it was only a name. Westwood 

 then created a number of new species from the males only, but figured them 

 in fine coloured plates. While some writers classify the species on the joints 

 in the antennae of the females, others define them by the anal appendages 

 of the males.

This fine mealy l)ug has a very wide range along the coast from New South 

 Wales to Perth, West Australia; the adult female usually solitary, resting 

 on the trunk or branch of one of the small white stemmed gums, sometimes 

 slightly hidden under the shelter of a bit of dried bark : at other times quite 

 imcovered (m the smooth stem. The adult female is of a general light brick- 

 red tint, with dark reddish-brown legs and barred antenna^ ; two longitudinal 

 stripes of dull puri)le extend down the whole length of the dorsal surface, 

 ami also show on the under-surface. She is broadly oval, convex on the dorsal 

 siirface, which is regularly segmented. Length, three-quarters of an inch, 

 arid broad in proportion. 



Tlu^ male is not unlike that of Iccrya jvirchasi.

The adult female of this species is brown, elongated, distinctly segmented. 

 Length about one-fifth of an inch. The antennae short, thick, seven-jointed, 

 third longest, rest subeoual. Cockerell forms a new genus for this species,
