and twigs of many young Eucalypts." Bulletin No. 13, of the New Zealand Department 
of Agriculture, under the title "The Gum-tree Scale" (by T. W. Kirk^.is devoted to it. 
It has caused much havoc on New Zealand Eucalyptus plantations, and remedial 
methods are suggested. See also Froggatt, Agric. Gaz., N.S.W., XI, 101. He has 
found it on at least half a dozen species of Eucalyptus. 
A " common gum scale," E. coriaceus, is figured by French in " Handbook of 
the Destructive Insects of Victoria," III, Plate cxvi. He mentions that he has seen 
it on saplings of almost every Eucalypt, including the leathery foliage of E. cdpina, and 
the Snow Gum (E. coriacea var. alpina). 
" Further Coccid notes, with descriptions of new species, and remarks on Coccids 
from New Zealand, Australia, and elsewhere," by W. M. Maskell, Trans. N.Z. In?t., 
XXIV, 1-67 (1891). At p. 26 we have Eriococcus confusus Maskell, with figs. 5-8 of 
Plate iv, on bark of E. viminalis from Victoria. On p. 27 we have Eriococcus eucalypti 
Maskell, with figs. 6-14 of Plate v. Stated to have been found on the W.A. E. diversi- 
color at Adelaide by Mr. Crawford, but more commonly on Bursaria spinosa, and Maskell 
suggests the inappropriateness of the specific name. At p. 29 we have Eriococcus 
teppcri Maskell, with figs. 15-17 of Plate v. Found onE. globulus and Burs aria spinosa. 
Eriococcus simplex Maskell will be found described in Trans. N.Z. Inst., XXIX, 317 
(1896), Plate xxi, fig. 3. On an undetermined species of Eucalyptus. Var. dealbata 
Maskell is from E. calophytta, Western Australia. Mr. A. M. Lea says, " Seems to 
prefer the butts of Red Gum trees which have been cut down, and from which young 
shoots are growing." Eriococcus spiniger Maskell (described in Trans. N.Z. Inst., 
XXVIII, 398(1895), Plate xxi, figs. 9-11), on Eucalyptus, was exhibited by Froggatt 
(Proc. Linn. Soc. N.S.W., XXI, 382 (1896) ). 
Dactylopius eucalypti Maskell in Trans. N.Z. Inst., XXIV, 35 (1891), with Plate 
vii, figs. 9-13. Collected " in Australia" (Maskell often did not quote the State) on 
bark of E. amyrjdaUna (? radiata). 
4. Sub-family Tachardiinae. 
Froggatt says we have five species from Australia. At Plate xxxvi of Mr. 
Froggatt' s work, Tacliardia decorclla Maskell, found on Eucalyptus, is figured. 
5. Sub-family Idiococciina). 
Spharococcus Maskell. ' The Australian species attack Eucalyptus, Melaleuca, 
Leptospermum, andCasuarina." For a figure of one of them, see S.fcrrufjineits Froggatt 
on Melaleuca sp. (Proc. Linn. Soc. N.S.W., XXIII, 378). 
6. Sub-family Brachysceliina?. 
All the members of this Sub-family are found only on Eucalyptus, and are hence 
intensely Australian. The distribution of the Brachysceliinaj has been merely touched, 
and I am hopeful that my present compilation will show how little we know of this 
Sub-family, and will lead to additional information being secured, which will result 
in generalisations as to the relations between the insects and their hosts.
