The Zroko or Odiim has been and is regarded as a Fetish tree. 
Iroko wood is also suitable for furniture, as it is very ornamental 
when polished, RE A a combination of the character of satin and

Its botanical identity was ema pn so at Kew. It prov ga to be the 
product of Chlorophora excelsa, Benth. and Hook. f., and is a near 
ally of Fustie (Chlorophora tinctoria), the енй Чуе- ee of the

CLXXXIX.—PHYLLOXERA. 
The ravages of the Phylloxera upon the vine have been the subject 
of numerous notices in the preceding volumes of the Kew Bulletin : 
vol. Ш. p. 66, Phylloxera in Asia Minor; р. 230, Phylloxera in South 
Africa; p. 236, Erroneous Report of Phylloxer ra in Greece ; p. 255, 
Regulations at the Cape ; vol. iv., p. 36, Phylloxera in Victoria. 
The present position of the struggle between the vine and this 
ineradicable pest is conveniently summed by Mr. C. V. Riley in the 
sep ion extract from his annual address to the second annual meeting 
e Association of 1 Economic Entomologists, sae in Insect Life, 
= Tauta Б of the Division of Entomology of the United 
States Department of Agriculture for January 1891. "Mr. C. V. Riley 
add, the leading authority in Economie Entomology at the present day. 
“The Grape » Phylloxera has continued to attract the attention, not 
only of most European been = also of those of Australia and 
New Zealand. It continues its spread in France, having at last invaded 
the more valuable champagne eroe The last report of the Superior 
. Phylloxera Commission of that country shows that about 240,000 acres 
` 
have undergone defensive measures, submersion being employe 
72,000, bisulphide of carbon in 145,000, and sulphocarbonate of мел: 
sium in 23,000. The ить ДК а at an end in such Departments

have most ‘effectually ee Po while the wine-growers of Algeria, 
pen ltaly, Portugal, Hungar y, Austria, and Безе are all 
battling against it, and are all more or less aided by their respective 
governments. 
The advent of the insect in New Zealand has been the cause of much 
writing and of much legislation there, and the government has been 
quite anxious to get t the best and latest information on the subject. 
There is very little that is available in the way of published experience 
in this country, as my Missouri reports are now very difficult to obtain. 
I would repeat here in substance what I have recently written to Sir 
F. D. Dell, Agent-general at London for New Zealand, because the 
demand for the information is continuous, and our own people are, to a 
great extent, unfamiliar with ES fi acts. 
During the more - twenty years’ struggle in France against the 
species innumerable remedies PER been proposed, most of which have
