Asterolecanimn petrophilcB, Fuller. 

 Trans. Ent. Soc, London, p. 456. 1899. 

 This scale was found upon the foliage of Petrophila linearis growing on the 

 banks of the Swan River, Western Australia. 



The female test is yellowish green, with a white fringe, flat, circular, hut 

 sometimes slightly elongated. Length 004 inch. This semi-transpaient 

 test has a blackish tint from the enclosed female and looks something like the 

 test of an Aleuroyd. 



" Adult female with antennae aborted, nientum monomerous, margin with 

 a single row of figure-of-eight spinnerets and a row or simple pores."

This is the common cosmopolitan oak scale of Europe, which is also recorded 

 from North America, the West Indies, and Mauritius. About 1895 it was 

 found in Nelson, New Zealand, upon the oaks, and in the following year 

 Fuller reported it upon many of the oaks in Hyde Park and the Botanic 

 Gardens, Sydney. 



The adult females form their circular glassj^ yellow tests at the extreme tip 

 of the twigs, half buried in the bark, with the upper surface convex, and 

 irregularly rounded. Diameter about yV of an inch. 



When the tips of the oak twigs are badly infested, the three or four ter- 

 minal leaves turn brown and die, and every twig may be sometimes infested 

 in this manner, but otherwise its presence does not seem to affect the health 

 of the tree.

This is the common native species with a very wide range over Austraha 

 and Tasmania, and though described on Styphelia richei and Leptospermi/m 

 bushes, infests many other native shrubs and plants.
