(9) Careya australis—aA common tree of the forest lowlands. A 
few trees were observed loaded with beetles, in December, 
1911, but these are the only records. 
(10) Common Cultivated Bananas.—Banana plantations are 
frequently visited by the beetles, numbers of the plants being 
badly eaten, leaving only the midrib. 
(11) Wattles (Acacia sp.) —The wattle, known locally as the 
black wattle, is a rather favourite food-plant. It rarely 
reaches a height of 30 feet, but the small saplings are usually 
attacked. Another species of wattle, growing with this one 
in the forest areas, has not yet been observed eaten. 
(12) Melaiewcas—Three species of the genus Melaleuca grow 
commonly in the forest around Gordonvale, two of which bear 
white flowers, the third beautiful pink blossoms. One of the 
white-flowered species is especially common, growing in the 
low-lying areas where water often lies for several months in 
the year; this tree is preferred to a very great extent, being 
usually favoured when attaining a height of from 15 to 30 
feet, and the same clump of trees has been found to yield 
beetles each day for a month. The two other species are 
not used as food-plants to nearly such an extent. 
(13) The Ironbark (Eucalyptus siderophloia (?), or crebra 
(?)).—This tree is met with on the higher forest lands, and 
is thus seldom situated near canefields. Odd trees growing 
alongside canefields were several times noticed infested with 
beetles. | 
(14) The Bloodwood (HFucalyptus corymbosa (?))—A_ very 
common tree right throughout the forest, except in the very 
swampy lands, and rarely attaining a great height. Small 
trees are frequently attacked by the beetle, 
(15) Moreton Bay Ash (Kucalyptus tesselaris).—Scattered 
throughout the forest, but not common. By far the favourite 
food-plant of albohirta, trees of all sizes being defoliated 
indiscriminately, and in the beetle season one rarely finds 
one of these trees within a mile or more of a canefield that 
is not infested, while the surrounding trees are totally devoid 
of beetles. 
The observations noted above serve to show that Lepidiota 
albohirta is partial to the foliage of certain trees, while numbers are 
never attacked. Thus, among the common trees growing in the vicinity 
of canefields around Gordonvale, Eucalyptus tesselaris, E. corymbosa, 
Melaleuca sp., Black Wattle, Banana, and the species of Ficus are most 
often attacked; while such common trees as Careya australis, Tristania 
suaveolens, Eucalyptus platyphylla, the Mango, and the second species 
of Wattle are rarely if ever chosen as food.
