liowevGr, readily destroyed, but owing to theii’ restless disposition 
can with difficulty be reached. Fortunately, however, the larva 
is pursued by a small bright metallic hymenopterous insect with 
lance-shaped hind body and short ovispositor . This parasite lays its 
egg within or upon the young Psylla. At the present time the eggs 
of the Psylla upon the leaves of our IMoreton Bay figs are in 
process of hatching, and it is an interesting sight to notice these 
little friendly insects moving stealthily amongst the destructive 
larvfe with wings folded back depositing their eggs one by one 
in them, the latter as yet for a short time unprotected by their 
glutinous secretions. 
2, The second injurious insect is a beetle which when adult 
ardls a round hole in the young shoot just below the terminal 
bud and feeds its way upwards through the centre of the wood. 
Growth is consequently retarded, and the shoot breaks oft. 
Neither this injury nor the insect which occasions it seems ever 
to have been remarked. The latter belongs to a family of very 
notorious timber-destroying insects— namely, the Scolytidee ; 
and may probably prove to belong to an undescribed genus allied 
to Phloetribus. It is a very stout, short, parallel-sided, dark 
purplish-brown beetle, having an obscure light-coloured band 
widely bounding the thorax behind. It measures a ou -(,111. in 
length. It is probably equally destructive m its larval con- 
dition, but its early stages have not as yet been obseiwed. 
3. A third destructive insect from the Moreton Bay hg also- 
belongs to the order of beetles. It is a remarkable inember of 
the Anthribidie related to Montrouzier’s genus Proscopoihinus, 
hitherto found only in New Caledonia. A curious feature 111 it
