The Gonipterinso section comprises a number of diverse forms. The genus 
Oxyops contains a number of stout moderate-sized beetles which are remarkable for 
the curious habits of their legless slug-like larva?, which, covering themselves with a 
slimy secretion, crawl about over the siirface of Eucalyptus leaves, feeding upon the 
epidermis and covering their backs with their excrement. (Froggatt, p. 185.) 
Oxyops concreta larvae feed on the leaves of E. longifolia, only eating the outer 
surface and often completely skeletonising' each leaf. Flemington and Rookwood, 
Sydney. 0. Hapei larva similar in habits to that of 0. concreta, but seems to gnaw the 
leaves in a more patchy manner. It feeds on the leaves of the Ironbark, E. sideroxylon 
(given as E. leucoxylon), at Bendigo, Victoria. (Proc. Linn. Soc. N.S.W., xix, 124, 
1894.) 
Aterpus cultratus is found generally on small Gum trees. Collected by Mr. 
Froggatt on E. corymbosaat Manly, Sydney. (Proc. Linn. Soc. N.S.W.,xx, 328, 1895.) 
Bryachus squamicollis has a wide range over Australia, and is usually found 
clinging to the twigs of stunted Gum trees ; it measures about half an inch in length; 
is of a uniform dark chocolate brown, but thickly mottled all over with fine grey and 
black scales. (Froggatt, p. 185.) 
The genus Lcemosaccus contains a number of short, flattened weevils. They 
are generally found feasting upon the bark of freshly fallen tree-trunks, particularly 
Acacia and Eucalyptus , in which they also bore holes and deposit their eggs. (Froggatt, 
p. 188.) 
The genus Haplonyx contains a number of curious, short, broadly-rounded 
beetles generally found clinging to the twigs of Eucalyptus, but their larvae breed in the 
fleshy galls of the Brachyscelid coccids, where they destroy the gall-makers and pupate 
in the cavity. 
Family Cerambycidae (Longicorn Beetles). 
The genus Phoracantha contains a number of typical dark yellow or mottled 
. brown beetles which in the larval state feed between the bark and sapwood of different 
Gum trees when the trees are dead or dying ; several species are common in firewood 
blocks around 'Sydney. P. tricuspis lives in Ironbark timber. (Froggatt, p. 192.) For 
attacks by these beetles on trees of E. hemipMoia var. albens in the Gunnedah district ; 
see this work, Part LVIII, p. 232. Mr. C. French calls P. tricuspis and P. recurva 
" Yellow-box borers," and at Plate CXII, Part V of his " Destructive Insects of 
Victoria," they are seen making galleries in ' the timber of the Yellow-box 
(Eucalyptus mettiodora). 
The larvse of Scolecobrotus westivoodi feed on the stems of E.corymbosa at Botany, 
near Sydney, attacking them about a foot above the ground; it bores upward, hollowing 
out the branches; it then turns downward and gnaws round the top of the stem where 
it first entered, thus killing the branch. (W. W. Froggatt in Proc. Linn. Soc. N.S.W., 
xix, 114, 1894.) 
Under the name of " Masters' Gum Borer," G. French, in " Destructive Insects 
in Victoria," Part IV, figures Tryphocharia mast&rsi. He states that the larvae of this
