Lecanium sp. 
In 1909 Compere introduced a Red Sciitellista from the Philippine Islands, 
but it failed to become acclimatised. 
Lecanium persicae F. (Vine Scale) 
This introduced coccid was finst recorded from Perth in 1901. Several 
parasite introductions ha\'e been made and a considerable degree of biological 
control has been acliieved. 
The wasp Aphycus timbcrlakei Ishii was introduced from California by 
Ceorge Compere in 1907 and is now well established throughout the South-\^^est. 
Four other unidentified species, one from Italy (Anon. 1903), two from 
France (Despeissis 1906) and one from California were introduced, but without 
success. 
Coccophagus lecani Walk, was also introduced in 1907 from California 
and 1,500 were released in the metropolitan area, but failed to become estab- 
lished. 
Myiocnema co)nperei Ash. was introduced by Compere in 1902 and, 
•although established, is of doubtful value (Essig, 1931).*

Pseudococcus Spp. (Mealy Bugs) 
In 1902, Compere introduced colonies of CryjAolaemus montrouzieri Muls. 
from New South Wales and Queensland and some 1,300 were liberated in the 
Metropolitan Area. The ladybird is now firmly established and is an important 
factor in Mealy Bug control.

F. BRUCHIDAE. 
Bruchus pisorum Linn. (Pea Weevil). 
The pea weevil was first recorded in Western Australia in 1931 (Newman 
1932). It is widely. distributed in the major pea-growing districts of the South-
