THE TASMANIAN NATURALIST. 
Another highly remarkable genus, the 
species of which also form galls on she- 
oaks, is Cylindrocoocus. lliu spec-ies of 
this genus are fairly numerous m Aus¬ 
tralia and Tasmania, but of none is the 
male known. In a common Tasmanian 
species the height of absurdity in 
shape appears to be reached. After 
the first stage the insect is not fixed, but 
is capable of moving up and dawn Its 
gall. It has no rostrum, and receives alt 
its nourishment through its skin (in part 
of tile second stage it appears tc be at¬ 
tached byi the whole top of its head to 
the base of tiie gall). The antennae 
are present, hut are little more than two 
feebly pointer) projections. There are 
no eyes. There are three pairs of legs, 
each apparently without claws (few other 
■insects with legs are known in which 
these are not terminated by claws); the 
front pair are the smallest, and are nar¬ 
row and produced; tin; hind 1'iiv are much 
larger, and are bladder like, whilst the 
middle pair are much larger still The 
front and hind legs appear to he com¬ 
posed of only one part, in stent) of five 
(coxa, ti'oolmntor, femur, tibia, and tar¬ 
sus), whilst the middle are composed of 
two. The legs moreover, alter 4n pro¬ 
portion, as the insect grows. The hinder 
parts of tiie body are Aotried with long 
golden hairs. The whole insect, how¬ 
ever, is so densely clothed with 
whitish meal that until this is re¬ 
moved the different parts cannot be 
clearly seen. A remarkable feature of 
this •Insect is the fact that when at¬ 
tacked by parasites it appears to grow 
mudi more rapidly, and to a much larger 
size than when healthy. The proof of 
this Is that in the galls ttend coccids may; 
frequently be seen that have become 
bloated to four or five times their nor¬ 
mal size, and exactly filling the galls for 
the greater part of their length; when 
so bloated the legs can he traced with 
great difficulty only. The gill of this 
species is narrow, about an inch in 
length, and tapers to a point; in colour 
it is green, but light brown at the top 
and bottom; at the bottom sealc-like 
growths are formed, so that the whole is 
remarkably like the young '.eaves of the 
tree on which it grows. Another gall 
formed by a species of this genus is so 
unlike the work of an insect and so much 
like that of a part of the tree itself that 
it deceived a botanist, who described it 
as the fruit of the tree. The drawings 
(published in the “Courier” of March 9) 
show various stages in the life histories 
of these insects, (a) Larva of Frendiia 
Casuarinae, with legs, eyes, and antennae, 
and capable of free motion, (b) Second 
stage, as enclosed in gall, and having 
lost legs, eyes, and antennae, (c) Third 
stage, (d) Fourth, or wad-like stage, 
with removable cap. (c) The enclosed gall 
insect of Cyliiidrocodeus. 
January Meeting. 
The monthly meeting was held in the 
Masonic, llal! on January 21<st. Mr. S. 
Clemes presided, and there was a good 
attendance. 
Miss D. Koi'niode and Master Win. 
Kermode were elected members of the 
Club. 
Mr. A. M. Lea, Government Entomolo¬ 
gist, showed two cases of beetles, etc., 
obtained by him at King Island, and de¬ 
scribed some of them. He also men¬ 
tioned that some bones of the extinct 
emu had been taken by him. Mr. Mor¬ 
ton gave some information regarding the 
bones that are to he found there. Two 
clutches of eggs of the Brush Wattle- 
bird (Acnnthoehoera mellivora) were 
exhibited liv Air. E. A. Elliott, and de¬ 
scriptions given of the nests and nesting 
grounds of these birds. Some eggs of 
one of the Cat-birds of Australia wore 
shown by Air. II. Bottenger. 
Air. A. Alorton, Director of the Tas¬ 
manian Museum, gave an account of his 
recent trip to the islands of the Pacific. 
He stated that he went to New Zealand 
from Hobart, and thence to the islands, 
many of which appear to be in a very 
prosperous condition, especially those 
under British control. Fruits, such as 
oranges, bananas, and pineapples, are 
grown in large quantities, and arc very 
profitable, while the chief industry of the 
islands is drying eoeoanut for copra, 
which is worth about '£25 per ton. Tiie 
natives are well developed, and good 
workers, their efficiency in the manage¬ 
ment of boats in tile surf and loading of 
vessels being quite remarkable. Descrip¬ 
tions of the scenery were also given by 
the lecturer. 
Dr. Gerard Smith then showed a num¬ 
ber of microscopic lantern elides of poly- 
zoa, hydrozoa, and radiolaria, mounted 
at the Afarine Biological Station at Jer¬ 
sey. At the conclusion the chairman 
it-ad the following letter:—“Hobart, 
21st January, 1007. Dear Sir,—The news 
inf your departure from amongst us lias 
been received very regretfully by the 
members of this Club, and we desire to
