beetle do considerable harm to tlio saplings of Eucalyptus nmygdalina (probably 
E. rndintn). and that it lias done much damage to cultivated trees of E. globulus around 
Melbourne, boring into the wood. 
I'n.ler the name " Apple Gum Bimia" Mr. French, in his " Destructive Insects 
of Victoria," Part IV, figures Bimia fcmoralis Saunders, which bores into the timber 
of Eucalyptus Mu<irtiun<i F.v.M. 
Under the name " Feathery Horned Yellow-box Borer" the same author, Part V, 
Plate CXVII, figures Disticliocera madeayi boring into the wood of Eucalyptus 
mclliodora. It also occurs in other species of the same genus. 
Family Chrysomelidae (Plant-eating Beetles). 
These are foliage-destroying insects, as a rule small. The genus Edusa contains 
a pumber of bright metallic coloured beetles of oval form, which are chiefly found among 
the foliage of Eucalypts. (Froggatt, p. 202.) 
The genus Paropsis is the most extensive and characteristic of all our plant- 
eating beetles. They are found chiefly upon the foliage of young Eucalypts. (p. 203). 
The active larva of Paropsis variolosa crawls about on the leaves of E. corymbosa, on 
which it feeds. (W. W. Froggatt in Proc. Linn. Soc. N.S.W., xviii, 38, 1893.) 
The genus Rhizobius contains a number of small black beetles, finely punctured 
and clothed with pubescence that gives them a rusty tint. R. veniralis is very common 
in the bush on young Eucalypts that are infested with Eriococcus coriaceus (p. 211). 
Family Bostrychidae (Auger Beetles). 
The larva? of Apati collaris feed on the dead wood of various species of Eucalyptus , 
living chiefly on the sapwood, which is completely riddled with irregular parallel channels 
which often cross and run into each other, and are all filled in behind as the insect 
moves along. Collected from E. hamastoma at Hornsby, near Sydney. (Proc. Linn. 
Soc. N.S.W., xix, 123, 1894.) 
ORDER VI (LEPIDOPTERA). 
(Butterflies and Moths.) 
Rhopalocera (Butterflies). Heterocera (Moths.) 
For a statement of the differences between Butterflies and Moths, see Froggatt, 
p. 230. The classification is, however, artificial, for there are " Connecting-link Moths " 
(p. 232) 
Family Hepialidae (Wood Moths). 
They lay their eggs upon the bark of different forest trees; the little caterpillars, 
after feeding for a short time on the surface, tunnel into the tree-trunk, becoming fleshy 
naked grubs which bore cylindrical chambers of various forms in the timber, in which 
they sometimes remain for years, finally pupating in the burrows. The moths are
