Anoplognathus cereus. (See Eucalyptus corymbosa.) 
I cannot, up to the present, trace any account of this species 
of Anoplognathus. 
Cicada moerens. The “Great black or Manna Cicada.” 
In the Prodromus of the Zoology of Victoria, by Prof. McCoy, 
Decade V., Plate 50, will be found admirable drawings of this 
insect, and also a full account of its life-history. From this source 
the few particulars following are taken :— 
The young resemble fleas in size and shape; they quickly 
reach the ground, into which they burrow, and whence they may 
be dug out at the roots of trees any time during the larval and 
pupa states. The larva is white, and seems to feed on under- 
ground roots ; the eyes, six legs, and antennz agreeing with the 
pupa, which chiefly differs in having the rudimentary wings visible 
at the sides of the body. The pupz ultimately come out of the 
ground, crawl up a few feet on the trunk of the nearest gum-tree 
in the night, ana then, splitting along the back, the surprisingly 
larger, winged, perfect insect creeps out, leaving the empty pupa 
skin clinging to the tree quite perfect, even to the smallest hair or 
other part, in the position of life. . . . Both sexes have short 
lives in the perfect state, and may be seen lying about the ground 
under the trees, dead or dying in abundance, after their noisiest 
few days. This particular species chiefly frequents Lucalyptus 
viminalis. 
Psylla Eucalypit. A homopterous insect which, on the 
leaves of Hucalyptus dumosa, produces “Lerp Manna’ (q.v). 
This and many other species are in the preparatory stages covered 
with a white cottony secretion, and their excrement forms threads 
or masses of a gummy sucreous nature. 
See a paper by Thos. Dobson, B.A., in the Proc. RS. Van 
Diemen’s Land of 1851, on the life-history of this insect. Excel- 
lent plates and full particulars of its life-history are given. A 
reprint of a paper by Dr. Anderson, of Edinburgh, on the same 
subject appears in the same volume.
