Family Thynnidse (Flower Wasps). 
The males of Thynnus fly about the flowers of Leptospirmum and Eucalyptus, 
and when captured bite and pretend to sting by turning up the tip of the abdomen, 
which ends in a horny, harmless process." (Froggatt, p. 100, " Australian Insects.") 
Family Apidse (Bees). 
In French's " Destructive Insects of Victoria," Part IV, is a coloured plate of 
" The Apple-tree Destroyer," Prosops pedisequus Buckton, which inflicts great destruc- 
tion on the cultivated Apple. Mr. French says that it has been ascertained that the 
natural home of the insect is in the wood of young Eucalypts. 
Mr. D. G. Stead exhibited specimens of a " Carpenter Bee," Lestis ceratus Smith, 
from the stem of a young Eucalypt in which they had bored a departure from the 
usual habit, in accordance with which choice is made of the flowering stalks of the Grass 
tree (Xanthvrrhcea). (Proc. Linn. Soc. N.S.W., xxiv, 476, 1899.)

Family Lucanidae (Stag Beetles). 
Mr. Froggatt recorded that he obtained the Golden Stag-beetle (Lamprima 
latreittei) from a dead log of Peppermint (Eucalyptus nova-anglica) at Uralla, N.S;W. 
Ceratognathus froggatti Blackburn. The larva lives in the bark of E. rdbusta 
at Botany. It excavates oval chambers about half an inch below the outer surface, 
where it lies lightly curled round (Proc. Linn. Soc. N.S.W., xix, 120, 1894). 
Family Scarabaeidae (Digger and Chafer Beetles). 
In a paper " On the habits and description of a destructive beetle (Melonontha 
destructor)" in Trans, and Proc. Philos. Soc. Adelaide, for 1877-78 (Vol. 1), p. 61, Otto 
Tepper discusses the destruction of Eucalypts (e.g., E. viminalis (?) and E. odorata) 
in the Monarto district of South Australia, through the stripping of the leaves by this 
new beetle. 
Machidius rugosus. The larva? live in the thick bark of E. rdbusta (near Sydney), 
in which they pupate. The beetle is found in crevices or under loose bark (Proc. Linn. 
Soc. N.S.W., xx, 331, 1895). 
Xylonchus eucalypti is a large cockchafer-like beetle about an inch long ; it is 
of a delicate pale grass-green colour, its under-surface and legs darker and thickly clothed 
with fine hairs. It feeds about Sydney on the foliage of E. robusta (Froggatt, p. 157). 
Anoplognathus viridceneus, the King Beetle, is our largest cockchafer ; A. analis 
is another, which destroys so many Eucalypts in the Sydney district and elsewhere.
