consignments of insects were received, containing 33,400 (32,600) specimens of which 11,200 (7,500) were blood-sucking insects. The number of lists of names sent out to correspondents was 128 (94)-Africa, 58; Asia, 40; Tropical America, 19; Australasia, 10; Europe, 1; and these comprised 3,501 (3,243) specific identifications.
Finance. As a result of the granting of self-government to Egypt, that country has withdrawn its contribution of £300 a year to the Bureau, but arrangements have been made for the Entomological Section of the Egyptian Ministry of Agri- culture to pay us £200 for the current year for general technical assistance, and it is hoped that this may be continued from year to year.
In Appendix I will be found an account of the receipts and disbursements for the past half-year; the interest on deposits is lower by £35 than that for the corres- ponding period of last year, but otherwise the items do not call for comment. The statement in Appendix II shows the amount of our available funds and an estimate of our liabilities for the remainder of the financial year, from which it will be seen that the unexpended balance of the Bureau Fund at the end of the year is estimated at £4,852.
"Bulletin of Entomological Research."-During the half-year another volume (No. XIII) of this periodical has been completed, and the following is a statement of the cost of production and the receipts by sales, etc:-

Although the volume is a few pages smaller than No. XII, the deficit is £50 more, owing to the much heavier cost of illustrations. This was mainly due to the inclusion of two important reports on tsetse flies, the two maps for which alone cost nearly £90. The sale of back parts brought in £40 more than last year, and the number of subscribers again shows a most satisfactory increase, being 241, as compared with 212, 194 and 188 in the three preceding years.
It has been found necessary to purchase and erect, at a cost of £38 15s., further shelving for the storage of the back parts of the Bulletin, and the packing and arranging of these with the greatest economy of space, on the same lines as was done for the Review of Applied Entomology last year, has now been practically completed. So far as can be foreseen, we have now a reserve space for some four or five years' further accumulation of stock.
Export of Parasites.-Dr. A. D. Imms states that since the last report a good deal of investigation has been done at Rothamsted in working out the life history of a second parasite of the earwig, another Tachinid fly, Rhacodineura Antiqua. and on 23rd October two cages containing 1,485 living bred earwigs were shipped out to New Zealand, a very large number of which were infected with this parasite, and they should yield sufficient flies to build up a strong colony. Owing to the very short pupal stage of this parasite and the absence of any information on the effects of cold upon the species, it has been deemed advisable to send out the larvæ within the living earwigs.
Additional material has also been bred of the other earwig parasite, Digono- chata setipennis, and it is intended to send out a further consignment of pupa in November. From information received from New Zealand they appear to be Home- what afraid out there that the earlier consignment has not established itself, because no pairing was observed in the cage, only a few flies emerging at a time. But the pairing might easily be overlooked in the insectary, and there is no real reason yet to anticipate failure.
On 10th August and 8th September parcels of first brood pear-slug cocoons were sent off to new Zealand. 980 cocoons in all, dissections of samples showing a parasitism of 66 per cent. The parasites sent last year were from the second broad of the pear slug and belonged to a different species of ichneumon, Perilissus Luteolator. The result of the latter shipment is not yet known as the insects arrived at the beginning of the New Zealand winter. Mr. L. J. Newman, Government
Entomologist of Western Australia, informed me that he would be glad to have parasites of the pear slug also, so arrangements will be made to supply them, but the second brood of the host has failed this year in England, so nothing can be done till next summer.

With regard to the Wheat-stem Sawfly in Canada, some closely allied species have been found at Rothamsted in large numbers, and two parasites of them appear to be tolerably common. Wheat is being sown in a specially constructed insectary this autumn, and it is intended to introduce both host and parasites next year when it is hoped that a sufficient number of the latter may be obtained for a preliminary sending.
A number of specimens of the Chalcid tsetse parasite, Syntomosphyrum glossina, have emerged at Rothamsted from material sent to us by Dr. W. A. Lamborn from Nyasaland. These have since oviposited in puparia of the "blue- bottle" (Calliphora), and a colony is being built up. It is probable that a consider- able number of parasitised puparia will be ready for transmission to Nigeria before Christmas.
The biology of the various parasites referred to above is being worked out, as it is important that their life histories should be known as fully as possible. It is intended to publish these observations as a help towards the work of parasite intro- duction, and an account of Digonochota is now nearing completion.
Pan-Pacific Science Congress.-In accordance with the decision of the Com- mittee I left London on the 13th June to attend the Pan-Pacific Science Congress in Australia, in company with Dr. E. J. Butler, Director of the Imperial Bureau of Mycology. We arrived at New York on the 19th, leaving the same evening and reaching Ottawa the next morning. Most of the entomologists were out in the country, and Mr. A. Gibson, Dominion Entomologist, was in London, where I had already. met him, but I was fortunate in seeing Mr. J. M. Swaine, Director of the Division of Forest Insects, and Mr. R. C. Treherne, Director of the Division Field Crop Insects. From them obtained much information as to the work of the Entomological Branch and inspected the laboratories and Experimental Farm; I also had a short interview with Dr. Grisdaile, the Deputy Minister of Agriculture. We left Ottawa late on the 21st June, reaching Winnipeg early on the 23rd and stayed there for twenty-four hours. The day was spent at the Agricultural College, where I met the Provincial Entomologist for Manitoba, Mr. Mitchener, who is working at pests of cereals, especially the Wheat-stem Sawfly, for which Mr. Gibson has asked us to secure parasites for export to Canada.
Leaving Winnipeg early on the 24th June we reached Vancouver on the morn- ing of the 26th, where we spent four days. The only entomologist there was Mr. W. H. Lyne, Provincial Entomologist for British Columbia, whose time is almost entirely occupied in port inspection work, a large and well equipped fumi- gatorium having just been built. Unfortunately the apple orchards of the Okanagan Valley were too far away for us to visit, as we had hoped, but we were able to see something of the large area under small fruits along the Fraser River. T. was also glad to meet in Vancouver Dr. Leslie Coleman, Director of Agriculture for Mysore, India, who has himself done good entomological work in Mysore, and is anxious to further its development. We left Vancouver at midnight on the 29th June in the S.S. "Makura" with two Canadian zoologists, Drs. McMurrich and Fraser, who were also attending the Congress.
Ten days later we called at Honolulu, where we were most hospitably enter tained by the local scientific men during our six hours' stay. Mr. F. Muir showed me over the very fine entomological laboratories of the Hawaiian Sugar Planters' Association, and I was also glad to be able to see the excellent fumigation station, probably the best equipped building of its kind, which is under the charge of Mr. E. M. Ehrhorn, of the Plant Inspection Service.
In another week we reached Suva, Fiji Islands. Unfortunately the Acting Government Entomologist, Mr. H. W. Simmonds, was away in New Britain, but we were shown round during our few hours' stay by Mr. R. Veitch. Entomologist to the Colonial Sugar Refining Company and formerly on the staff of this Bureau.
New Zealand was reached on the 21st July, and a fortnight was spent in the North Island only, the places visited being Auckland. Rotorua, Waitomo and Wellington. In the latter place we had a very sympathetic interview with Dr. Reakes, Director-General of Agriculture, and Mr. A. H. Cockayne, Director of Fields, was most kind in assisting us in every way he could. Thanks to the Gov- ernment Entomologist, Mr. D. Miller, I was able to get a good insight into the organization of the Entomological Section of the Department of Agriculture, in which much useful work has already been done, having regard to the facilities available. I was unable to meet the Assistant Entomologist, Mr. J. G. Myers,
