Family Geometridae (Loopers). 
So called because the larvte form their bodies into a loop when progressing. 
All the caterpillars of this family are remarkable for their protective mimicry, both in 
colour and form. 
Crypsiphona occultaria feeds on the foliage of Eucalypts and the whole cater- 
pillar strongly resembles a Eucalyptus twig (p. 260). The caterpillar of Gastraphoru 
henricaria also feeds on the foliage of Eucalypts (p. 262). Mr. Fletcher exhibited two 
moths (Ckrysiphora occuUans) bred from caterpillars forwarded by Mr. A. Simson, of 
Launceston, because of their striking resemblance to the leaves of the sprouting shoots 
of E. amygdalina on which they were found to be feeding (Proc. Linn. Soc. N.S.\\'., 
xxii, 44, 1897). 
Family Tineidae (including the Clothes Moths). 
The larva? of Tinea nectaria make cases out of Eucalyptus leaves according to 
Meyrick, but Froggatt says he has bred the species out of blister-like excrescences 
or galls from the leaves of a non-Eucalyptus shrub in the Botanic Gardens, Sydney 
(Froggatt, p. 281). 
Appendix. We have " Scribbly Gums," particularly E. Juemastoma and var. 
micrantJia and E. coriacea, so called because of the scribbles to be seen on the smooth 
surface. These scribbles were originally formed under the flakes of deciduous bark to 
be seen on every Gum. 
Mr. Froggatt tells me " we have never been able to satisfactorily define what 
insect or insects cause them. I believe that though there may be several ' scribblers,' 
most of them are caused by small moth larvae, and not beetles." 
ORDER VII (DIPTERA). 
Family Cecidomyidae (Gall Gnats). 
' All the members of this family are tiny little creatures, some of them micro- 
scopic in size, the males being remarkable for their beautiful feathered antenna?. Though 
many of them produce galls, there are others that do not . . ." The author quotes 
F. A. A. Skuse's work on " Australian Diptera." (Froggatt in Agric. Gaz. N.S.W., 
ix, 389, 1898.) 
A species of Cecidomyia causes thickening and bending of the young stem and 
fusion to the petiole in E. fuemastoma (White Gum), at Arncliffe, near Sydney (Misf 
Wilson), and a similar deformity in E. tereticornis, at Kendall, NSW (Dr J B 
Cleland). 
Diplosis paralis forms blisters on the leaves of E. corymbosa, Waverley, Sydney. 
. eucalypti forms woody swellings on the stems of E. hvmastoma at Botany, near 
Jydney (Proc. Linn. Soc. N.S.W., xv, 373). Diplosis paralis forms curious little 
sters upon the foliage of E. coryntbosa, dotting the leaves all over with reddish spots
