" Australian Psyllidse," Part III, W. W. Froggatt (Proc. Linn. Soc. N.S.W., 
XXVIII, 315 (1903)). 
This paper contains a note of Rhinocda eucalypti Maskell that it is to be found 
in every plan; nursery or garden about Sydney where E. globulus is growing, and that 
it has been found commonly on that species in South Africa. Mr. Froggatt describes 
two new species of Rhinocda, but does not say they are found on Eucalypts.

See Froggatt (p. 370). At fig. 4a, Plate 77, of my" Critical Revision of the Genus 
Eucalyptus" will be found a representation of depressions or pits on the leaves of E. 
Preissiana (seen also in E. palUdifolia). caused by the larvae of insects of the genus 
Aleurodes. 
Family Coccidae (Scale Insects). 
For a general account of the Coccidac interesting to us in Australia, see Froggatt 
(p. 371). They are divided into a number of Sub-families, including the following, and 
a few genera, which will be later referred to, are given in brackets : - 
1. Diaspina> (Mytilaspis, Chionanpis, Aspidiotus, Maskettia). 
2. Lecaniina3 (Ctencck'ton). 
3. Dactylopime (Eriococcus, Dactylopius). 
4. Tachard i i na; ( Tacluirdia). 
5. Idiococciinso(.Sp/wrrococcws). 
6. Brachysceliinae (Brachyscdis or Apiomorpha, Opisthoscdis , Ascdis, Carteria). 
Eucalyptus coccifera Hook., a Tasmanian plant which Hooker, in Bot. Mag., t. 
4637, calls the " Cc ecus-bearing Gum-tree," was named because it was infested by some 
coccid insect, which Mr. Lawrence drew attention to at the time. But this may have 
arisen from some confusion, for Mr. Leonard Rodway tells me that he has failed to find 
a coccus on this species. 
I now proceed to give notes on Scale Insects, so far as they affect Eucalypts :
