In publishing Part V., the last but one of the Destructive Insects of Victoria, I may remark that some comparatively new insect pests have been included, especially the more formidable of those attacking orchards, crops, and forests. As, in Part IV., it will be noticed that some prominence has been given to insects attacking our forests. In America, India, and Germany, where forestry has been raised to a " fine art," and a huge commercial success, whole volumes dealing with forest pests have been pub- lished, and no expense spared in enlightening foresters and others similarly engaged. The Commonwealth of Aus- tralia is singularly rich in valuable timbers, the utilization of which is creating a great commercial industry. It is therefore advantageous that all possible information regarding forest insects should be widely disseminated. As I have endeavoured to avoid technical names and terms as much as possible, it has been necessary to invent common names for many of the insects described. Fortu- nately, but very few additional orchard pests have to be recorded since the publication of Part IV., but, as we do not know the time when more of the native insects may leave their natural food to attack orchards, it follows that the distribution of practical and reliable information regarding them is a matter of urgent necessity. Some additional insect-destroying birds are also dealt with in the present volume. As these birds are absolutely indispensable to the welfare of the orchardist, farmei, and forester, it is to be hoped that, with the aid of the coloured plates, they may be readily distinguished from the fruit and grain-eating kinds. A2 4 DESTRUCTIVE INSECTS OF VICTORIA : Part YL, now in course of preparation, will deal also with beneficial insects, and will complete the series, which, when finished, should constitute a standard work for Australia on the subject of Economic Entomology and Ornithology. -y Following the preface is a very interesting Report, kindly furnished by Mr. J. G. Turner, Senior Inspector of Fruit Exports and Imports, and embodying the Regu- lations now in operation. The Report and Regulations will be helpful to both growers and shippers. At the end of the volume will be found a short summary of the latest spraying machines and materials placed on the market. In conclusion, I have to thank the Assistant Ento- mologist, Mr. C. French, jun., for the many interesting field notes and observations ; Mr. A. T. Sharp, for reading the work, both in manuscript and in proof ; and JVIr. H. Shelton for his assistance in the preparation of the Index. CHAS. FRENCH. Melbourne, December, 1910. O O X T E Ts^ T S Chapter.

G. Turxer). Melbourne, 1st December, 1910. With regard to the Vegetation Diseases Acts, there have been no further amendments since the issue of Part IV., but suggestions have been forwarded to the Hon. the Minister, and certain alterations and additions which will tend towards more effective working are now under consideration. The Regulations under this Act, on the other hand, have been revised, and considerable alteration has been made. In August, 1909, a Conference of State Ministers of Agriculture met in Melbourne to discuss the matter of restrictions on inter-State interchange of fruit, plants, &c. This was the second such Conference, the previous one having met in Sydney in February, 1908. It will be easily understood how such a course would tend to eliminate, to a great extent, the friction previously existing between the States. Many important matters were dealt with at the last Conference, and the Regulations of this State have been amended to carry into effect the resolutions passed at same. The following is the form m which the General Regulations relating to the importation of nursery stock, trees, plants, and vegetables stand at present : — REGULATIONS UNDER THE VEGETATION DISEASES ACTS. Under the powers in that behalf conferred by the Vegetation Diseases Acts to make Regulations among others for the purpose of regulating importation, intro- duction, and bringing into Victoria of any particular kind of tree, plant, or vegetable likely, in the opinion of the Governor in Council, to spread any disease or insect, and for prescribing penalties for the breach of any Regulation so made, the Governor of the State of Victoria, by and with the advice of the Executive Council, doth order as follows ; — General. 1. The Regulations of the 13th day of May, 1908, and published in the Govern- ment Gazette of the 20th day of May, 1908, shall be, and the same are hereby repealed. Interpretation. For the purpose of these Regulations, " RegLstered mark or brand " means any mark registered with and approved by the Department of Agriculture of the Stat© of fiXDOrtation. D. H.

I hereby certify that I have duly inspected the above-mentioned and have' found them to be, to the best of my knowledge, clean and free from Irish Blight in any stage of development, and from any other disease proclaimed in the State of Victoria. These have been grown in an area free from Irish Blight and have not been in or carried through any area wherein that disease is known to exist. Dated at this day of 19 Signature of Officer of Department of Agriculture. Official Designation Address Considerable fear for the safety of the potato industry was awakened towards the close of last year by the discovery of outbreaks of Irish Blight in this and other States. Vigorous steps are being taken by all the States in this matter. The local transfer of potatoes is under strict •supervision, and, as will be seen, ample provision has been made in the Regulations to prevent the disease being introduced in imports from other States. The Regulations fixing the fees to be charged for iaspection. &c., have been altered from time to time. Additions have also been made to the list of diseases given on pages 24-5 of Part IV. These are as follows : — Insects. Scientific Name. Common Name. Anguillulidse . . . . Eel-worms. Flies of the onion, cabbage, cauliflower. Sea. Nutmeg Beetle. y Beetles. All scale insecta. Sweet-potato Weeril. Anthomyiidae Arseocercus fasciculatus Bostrychidae Cioidae . . Scolytidae Coccidae Cylas formicarius 12 DESTRUCTIVE INSECTS OF VICTORIA : FUXGI. Scientific Name. Common Xame.

Telletia tritici . . . . J ^ , Ustilaginese . . . . Smuts. Potato scab. The inspection of shops, markets, barrows, &c., under the provisions of the Vegetation Diseases Act, No. 1773, is still being vigorously carried forward, and its effect is to be seen in the improved quality of the fruit now being sold. Many complaints have been received, from time to time, respecting the manner in which some salesmen defraud buyers by " topping up " their fruit. Seeds are also often mixed with inferior and cheaper varieties, or otherwise adulterated. The Hon. the Minister has been asked to take action to put a stop to these fraudulent practices. A short time ago he requested me to furnish him with drafts of Bills to deal with these matters. This has been done, and the new measures will shoi-tly be placed before Parliament. It Avas thought for some time that the Queensland banana industry was in danger of becoming extinct. The decline originated with the destrnction of a large number of plantations by floods. Shortly after this occurred, the new Victorian Regulations were issued, and drastic treatment was meted out to all fruit showing evidence of Fruit Fly. The growers of bananas took alarm at the severity of these Regulations, and representation was made that a responsible officer of the Depart- ment should be sent to investigate the conditions under which the bananas were grown and shipped in Queensland, and also to allay the fears of growers regarding the supposed stringency of our Regu- lations. Advice was required, as well, regarding the stage of maturity at which bananas should be cut, and also many other matters pertaining to shipment to this State. Under instructions from the Hon. the Minister, I left Melbourne on 6th September, 1909. I visited various plantations, met many growers, addressed numerous meetings, explained the requirements of our Regulations, and generally instructed those interested on all matters relating to the shipment of these fruits. Good results may shortly be expected ivom this visit. Already a great improvement is manifest in the size and quality of the bananas coming forward, and, as large additional areas are being planted, it is expected that there will also be a considerable increase in the quantities forwarded. REPORT OF SENIOR INSPECTOR, FRUIT EXPORTS 13 AND IMPORTS. On 1st July, 1909, the Federal Quarantine Act came into operation, and a considerable portion of the work previously performed under the Vegetation Diseases Acts is now being carried out under the Federal measure. This law provides for the inspection and, if necessary, the quarantine and treatment of plants (among other things). So far, the operation of the Act has been confined to imports from countries outside the Commonwealth ; but poAver exists to extend same to local transfer if the necessity should arise. The methods of examination, though somewhat more drastic from the wider scope of the Act, are, on the whole, similar to those which obtained under State law, and the work is still carried out by the officers of this Branch. The measure, on the whole, has been found to work smoothly. As it has, however, been in operation for little over a year, it is somewhat early to venture an absolute opinion as to its ultimate efficiency as compared with the State measure ; but the fact that it operates uniformly throughout the whole Commonwealth is a substantial argument in its favour. With respect to goods intended for export, those for other States, must be accompanied by a certificate, stating that they have beem examined and found free from disease. It is also necessary that all cases or other packages be new, and bear the name and address or the: registered mark or brand of the grower or exporter in letters of not. less than one half-inch in length. The following are additional Special Regulations in force in other States : — Queensland. — Vines and portions of vines are prohibited. Tasmania. — Plants must be fumigated prior to shi])raent, and are only perniitte.!- to land at Hobart, Launceston, and Devonport. South Australia. — Vines or portions of vines are prohibited entry. Plants or portions of plants must be accompanied by a declaration stating that they were grown at a greater distance than 50 yards of any grape vines, and that no Phyl- loxera exists or hr,s existed in the nui-sery or garden in which the plants have been growing. Western Australia. — Vines on arrival are grown in quarantine for one season. Albany and Fremantle are the only ports where plants may be landed. The examination of fruit, plants, &c., intended for export to countries outside the Commonwealth is carried out under the provisions of the Federal Commerce Act and Regulations. This measure prohibits the export of such goods unless they bear a true description, setting out the following particulars : — 1. The kind of goods. ■2. The net weight or quantity. 3. The name of the grower or exporter. 4. The name of the State wherein the goods were grown or produced. 5. The word "' Australia." 14 DESTRUCTIVE INSECTS OF VICTORIA : A " Notice of Intention to Ship." and a " Re(|ncst to Certify and Mark Goods with an Approved Stan\p," must be lodged at this office at least 24 hours prior to the advertised time of departure of the exporting vessel. The goods are examined, and, if they are found to be in accordance with the requirements of the Act, they are stamped, and a certificate issued. Some difficulty was experienced in efficiently dealing with trees, nurserv stock, &c., under this measure. As these are usually shipped in bundles, which cannot be properly inspected unless taken to pieces, it has been arranged that nurserymen desirous of shipping such should first notify the Chief Inspector of Orchards, who will, if the nursery he found free from disease, issue a certificate to cover a period. After such certificate has been granted, the Senior Inspector of Plant Exports should be notified, in order that all necessary certificates for export may be obtained. In connexion with the compilation of this report and the included Regulations, due credit must be given to Messrs. E. Meekmg and A. F. Parker, the officers who have assisted me greatly during this busy period (of the year. 16 DESTRUCTIVE INSECTS OF VICTORIA : PLATE XCIX. " Butterfly of the Orange " (Papilio Anactus, Macleay).

BUTTERFLY OF THE ORANGE. 17 CHAPTER CVI. Butterfly of the Orange. {Papilio Anactus, Macleay.) Order : Lepidoptera. Family : Papilionidce. This is a handsome but very destructive caterpillar, whose favourite food plant would appear to be the foliage of Orange trees. The late Hon. ^^'illiam Macleay first described the insect, giving particulars as to its life history, &c. : — "A cylindrical caterpillar, slightly .tapering towards each end (see Fig. III.), reaching a length of \\ inches; on the back are two rows of spines extending the whole length of the body, each segment bearing two. The third and fourth segment each bear an additional smaller spine below the former one. The colour of the segments is blackish-brown, with a few small yellow spots between them and at the side ; a large infero lateral yellow spot on the fifth and on each of the seg nents posterior to it. The external aspect of the abdominal prolegs and a spot at the base of each thoracic leg are also yellow. The fork- like tentacle on the neck is orange-yellow. (As the larva is somewhat difficult to figure correctly, the above descrip- tion IS given to enable any one to recognise it should it ap- pear upon their citrus trees.) The chrysalides (see Fig. IV.) are of a dirtv white, with greenish blotches. The chrysalis is attached bv its tail end, and is held in position by a loop of silk-like material surrounding the body at the junction of the thorax and abdomen." The perfect insect is not likely to be mistaken for any other Victorian butterfly ; the female, as usual in butter- flies, is larger chan the male. The eggs are deposited here and there upon che leaves of the orange, and, although small, are readily detected by the naked eye. The grubs are very voracious, and a few of these will strip a fair-sized plant of its foliage in a very short space of time. Ander- son and Spry state that the larval stage lasts about a month, and the chrysalis only ten days. 18 DESTRUCTIVE INSECTS OF VICTORIA : How this insect got here from New South Wales is not difficult to conjecture ; I feel certain that the pupae were introduced on young orange trees, the trade in which is very large and important. I am indebted to Mr. A. F. Thiele, the w^ell-known Doncaster orchardist, for having first brought this insect under notice when found attacking orange trees in his district. With the extension of orange growing in this State, it is not unlikely that other of the New South Wales and Queensland pests may be introduced, so that a careful inspection of all young citrus trees coming should be made at the port of shipment and on arrival in Victoria. Prevention and Remedies. Fortunately for our growers, this beautiful butterfly is not common in Victoria, and an occasional look over the foliage is about the best preventive, as the caterpillars are easily seen, and can be destroyed. The perfect insect, as our plate shows, is conspicuous, and may be caught by means of a roughly-made net, so as to prevent egg-laying. Should the caterpillars be plentiful, hand-picking would, of course, be out of the question, but an occasional spraying with arsenate of lead or Paris green Avould suffice for the purpose ; 1 lb. of the latter, and 4 lbs. of lime to 180 gallons of water for orange foliage. The pupae of this butterfly appear liable to the attack of insect parasites. Fig. V. shows a pupa with hole on side. Mr. H. Tryon remarks that an hemipterous insect belonging to the family HalydidcB has been observed by him to attack the caterpillars of this butterfly as they fed on a young plant. It inserted its rostrum or beak into the flesh of the caterpillar, and then sucked its body juices. Mr. Tryon also speaks of having bred large dipterous insects belonging to the genus Tachinus from caterpillars of Papilio ereciheus^ called by Anderson and Spry the Orchard SwaHow Tail. This latter butterfly is rare in Victoria, but common in New South Wales and Queensland, where it is a bad enemy of the orange grower. There is a third species of Papilio BUTTERFLY OF THE ORANGE. 19 which is rarely found in Victoria, although it has a wide geographical range ; it is a tropical species, and closely allied to the Indian P. erithronus. A small bird, Zostewps coerulescens, or White Eye, is said to be a great destroyer of these caterpillars ; but, as these birds are great pests of the fruit-grower, I cannot advocate their protection. In Victoria, Tachinid Flies are not uncommon, so we can look upon them as useful helps in the orchard. 20 DESTRUCTIVE INSECTS OF VICTORIA PLATE C. " Metallic Tomato Fly " (Lonch^a splendida). Fig. I.

METALLIC TOMATO FLY. 21 CHAPTER CVII. Metallic Tomato Fly. ( LonchcBct splendida . ) Order : Diptera. Family : Trijpetidre. This pest is a very handsome fly, belonging to the real " Fruit Flies," It is of a metallic bluish-green in colour, and, less than half the size of the common house fly. The body is tapered in shape, and the wings are of a smoky-pink colour, which speedily fades after death — a colour difficult to reproduce in a drawing. The larva is not unlike that of some of the ordinary fruit flies, but smaller and very active. Major Broun, F.E.S., of New Zealand, describes the body of this insect as glossy, dark bronze-green, head and legs black, basal joint tarsi, testaceous. The eyes of this insect are very large and prominent, the body being somewhat short and plump for the size of the insect. This insect, so far as can be ascertained, is an importa- tion from New South Wales ; at least, it was first observed here in tomatoes imported from that State. Mr. Froggatt speaks of Lonchcea being found in New Zealand and in the Pacific Islands, and it would now seem to have spread to most parts of Australia. It has been stated that this fly will only attack fruits, &c., when the latter are either nearly ripe or have been bruised in some way. In Victoria, our experience is that it will tackle fruit, especiafly tomatoes, upon which no bruises or abrasions of any kind can be detected, even with the aid of a good lens. It is giving no end of trouble, and many cases which were thought to have been attributable to the Fruit Fly {Halterophora capitata), or the so-called Queensland Fruit Fly {Dacus Tryoni), have been traced to the depredations of this tiny insect. 22 DESTRUCTIVE INSECTS OF VICTORIA : Our plate sliows the larva, pupa, and the perfect insect, both life size and. magnified, and also the grubs at work in a tomato. Mr. Froggatt says that in New South Wales it infests decaying tomatoes, potatoes, egg-fruit, and other of the Solanacece. In Victoria, the chief trouble would appear to be in the tomato, and hundreds of acres have been ruined by this pest, and the fruit rendered absolutely unfit for use. In speaking of a closely allied fly, Drosophila, Major Broun says — " This little cosmopolitan fly has become a great nuisance, especially during warm weather, when it attacks all sorts of fruit, more particularly bananas, oranges, and pineapples which have been bruised or begun to decay. If it confined its attention entirely to decaying fruit we might class it, along with many useful insects belonging to diflerent orders, as a natural scavenger or sanitary agent, but it unfortunately also commits havoc with good fruit that has been cut. In order to test its habits more thoroughly, I left uncovered two Australian pineapples, out of which I had cut the maggots of the Queensland Fruit Fly (Tephritis Tryoni) in my office on the wharf last February. All decayed or infested portions were carefully cut away so that the exposed surface was perfectly good and sound. A few of these flies were in my office ; they soon found the pines, and it is no exaggeration to state that within a fortnight hundreds of their maggots and chrysalids occupied the fruit, whilst the newly -emerged flies annoyed me so much when writing that I had to clear out the whole brood. Similar experiments with oranges and bananas need not be detailed, as the case of the pineapples show how prolific the fly is." The genus Drosophila is well known to vignerons and fruit-growers, the former especially, as the tiny fly which infests the wine casks in the summer. My reason for giving the experiences of so capable an entomologist as Major Broun is to support the views which I have myself held regarding the Fruit Fly, which have been so frequently METALLIC TOMATO FLY. 23 contradicted, viz., that it will attack bananas. It is, therefore, necessary that we should carefully examine these fruits on their arrival in our State. It would be a difficult matter to place a limit on the numbers of different kinds of fruit that the fruit flies will attack, so that we cannot be too careful regarding imported fruit from Queensland and elsewhere. It would be interesting to know, if possible, some of the details of the over-wintering of Lonchcea and insects of a somewhat similar kind. Many a time the larva of this fly in tomatoes has been mistaken for those of the genuine fruit fly, but we are glad to find that our determined stand when the Mediterranean Fly (H. capitata) made its appear- ance here, has led to the very best results. Prevention and Remedies. All tomato plantations should be kept free of weeds and rubbish of any kind. The land should be constantly stirred, and never allowed to become either too dry or too wet, so that the plants may be kept in full vigour. In small garden patches, fine mesh nets could be used, but on larger areas an occasional spraying with quassia chips as a preventive should be carefully and consistently given. It is somewhat unfortunate for Victorian growers that the Chinese, although most successful vegetable gardeners, are indifferent to our recommendations, and, unless abso- lutely compelled, will rarely take the precautions necessary to protect their gardens or orchards from the inroads of this or other pests, and thus it happens that these are some of the principal breeding-places, both for insect pests and also for those of fungus origin. When tomatoes, &c., are found to be affected with the grubs of this fly no time should be lost, and a gathering up of all infested fruits, tubers, &c., should be at once resorted to. These should be boiled, and fed to either pigs or fowls, but in no case should affected fruit, &c., be given 24 DESTRUCTIVE INSECTS OF VICTORIA : without having been boiled or well scalded, as the larvae are not easily destroyed by ordinary methods. Should potatoes be affected, sprinkle occasionally when pitted with lime, turnincf the tubers over at the same time. This treatment will be beneficial in man}^ ways, as it prevents " sprouting," and also the attacks of the larvae of the Potato Moth {Lita solanella). 26 DESTRUCTIVE INSECTS OF VICTORIA PLATE CI.

Dark-striped Tiger Moth. {Diacrisia canesce7is, Le G.) o Light-striped Tiger Moth. {Artices glatignyi, Butler.) Order : Lepidoptera. Family : Arctiidce. These are two moths which, in the larval state, are very destructive to cereals and herbage of many kinds. Figs. IV. and V. on the plate are those of the Light-striped Tiger Moth {A. glatignyi), the larva of which feeds on the Native Hop {Goodenia ovata). This species is not so plentiful around Melbourne as is the other one shown on Fig. YL, but the larvae sometimes occur in large numbers, and when hungry will tackle almost anything of a succulent nature. The male, as shown, is smaller than the female, and is somewhat lighter in colour. Both sexes remind one somewhat of the well-known Tiger Moth of English hedge- rows. The larvae or caterpillars of these moths are hairy, and frequently may be seen in large numbers. As a rule, birds do not seem to be partial to them. The Diacrisia canescens, or Dark-striped Tiger Moth, is a very common and destructive insect. The larvae- do much damage to garden plants of all kinds, and especially to cereal crops. The eggs are deposited among weeds on neglected headlands, and when hatched the young feed ravenously. The cocoons are deposited near the base of the tussocks, and are partly covered with grass, as our plate shows. This species is much the more plentiful of the two, and does damage that other insects are credited with. The larvae feed mostly by night, and hide by day. 28 DESTRUCTIVE INSECTS OF VICTORIA : Prevention and Remedies. On cultivated areas, cleanliness is the mam point in preventing attacks bv insects of this class, as when grass or weeds are permitted to grow on headlands, these places are harbours for insects of all kinds. They are also covers for egg-laying, so that it will be seen that without clean cultivation the chances of escape from these pests will be considerably lessened. Trapping in places where stock is not admitted is about the best method of destroying the caterpillar. It is done by growing strips of such plants as appear to be most relished by the grubs, and spraying the same with either Paris green or arsenate of lead. In some cases, fungus parasites especially prove valuable auxiliaries to the grower. Mr. E. Anderson, writing of the larva of a common Victorian moth {Apina callisto), says — " They are kept in check by a parasitic fungus, whose spores find a suitable germinating place in the bodies of the caterpillars, eventually choking up their whole system with a white corky substance, and, as the year is favourable to the abundance of the Apina, seem equally favourable to the spread of the fungus." There is no doubt that fungus parasites help materially to keep certain of our insect pests in check, and it is a common occurrence well known to observers in the Victorian bush, to see dead grasshoppars in large quantities fastened on to the tops of rushes or other plants, and even on dead twigs. The bodies of. these are found to be empty and shrivelled, but without any apparent cause, which, however, a powerful lens will at once disclose. It is also no uncommon sight to see cater- pillars hanging limp and decomposed from twigs ; the rapid action of the bacteria soon causes the death of the most robust caterpillars. The question of parasites as aids to destruction is as yet in its infancy, but the subject is a useful and interesting one, and should be closely studied, especially by those engaged in rural pursuits. 30 DESTRUCTIVE INSECTS OF VICTORIA : PLATES CIL, cm.

Common Thrips. {Thri'ps tahaci, Lindemann.) Order : Thijsanoptera. Family : Thripidoe. This is a singular little insect, characterized by long narrow membranous wings with long cilise or hairs, as shown in our enlarged figures. The pupa and perfect insects are very active, and almost too minute for a popular description ; but when a plant or flower is badly affected, the whole appears to be covered with tiny, narrow, dark specks, which can hardly be determined with the naked eye. The species under notice is an introduction from Europe, and has long been known in England and elsewhere as one of the gardener's worst enemies,especially to plants growing under glass. The eggs are deposited on the food plant, which is, however, by no means limited to any particular kind. Thrips are the greatest of all troubles to the rose-growers of this State, and appear in countless millions as if by magic. In Europe, an insect known as Thrips cerealium is a great pest of the wheat-grower, and in some instances has been known to do a vast amount of damage to the crops. Other thrips, known as Gall-making Thrips, have been described by Mr. Eroggatt. These singular bladder-like galls were found on the leaves of Eugenias and other ever- green plants. Our plate shows a rose bloom and bud absolutely deformed through the attacks of these tiny creatures. They are equally severe on apples and other blossoms, and frequently prevent the fruit setting. In Russia, Dr. K. Lindemann, in his studies of these insects on the tobacco plant, found the life cycle to be as follows : — Development of egg, 10 days ; development of 32 DESTRUCTIVE INSECTS OF VICTORIA : larva, 30 days ; development of nyraph, 7 days ; total development, 47 days. In Florida, Professor Qiiaintance found it to be as follows : — Development of eggs, 3| to 4 days ; development of larva, 7 to 9 days ; development of nymph, 4 days ; total, 10 J to 13 days. Experiments will be made by the Entomological Branch to ascertain, if possible, the difference in time of development as compared with the above results. During the past few years, in Victoria, these troublesome insects have been very severe on potato crops in many parts of the State, and for the benefit of growers I have included the report of the Assistant Entomologist, Mr, French, jun., who, with Mr. G. Seymour, Potato Expert, has been conducting some important experiments in the Romsey and Lancefield district. He writes — " In com- pany with Mr. Seymour, Potato Expert, I paid a visit to Romsey and Lancefield, and inspected the potato crops, and was surprised at the damage to them done by the thrips. Mr. Seymour estimates this season's loss at several thousand pounds at least. Last year the loss was about eight thousand pounds. The thrips are simply in millions, not only affecting potatoes, but also the pea crops, grasses, hawthorn and African box-thorn hedges, and, in fact, nearly every kind of plant. There is thus great difficulty in effectively dealing with the pest. The lower leaves of the potato plant are generally attacked first, and, after these are destroyed, the top ones are affected, and in a short time the whole plant shrivels up, and the potatoes are often only the size of a small marble. I may mention that on one pea leaf no less than 23 larvae of the thrips were counted. This will give some idea of the enormous number of these insects. Messrs. Robb Brothers very kindly placed part of their potato crop at our disposal for experiments, and I desire to tender them my best thanks for their assistance. Mr. Seymour procured the loan of a Strawsonizer spraying outfit from a firm in Melbourne. This was fixed up in a dray. COMMON THRIPS. So It worked .very satisfactorily, the spray being forced up under the leaves, and other nozzles distributed the spray on the uppersides of the leaves, so that the plants were thoroughly soaked. The materials used were tobacco- water and benzine emulsion; the former with good results, but there is the drawback of having to strain it before use. If it is used in large quantities, it should be made in the winter and stored for use in the early summer, when the thrips make their appearance. The benzine emulsion, in the proportion of one in six, also proved very effective, every insect reached by this mixture being killed at once. This spray has the advantage also of being cheap. Messrs. Robb were well satisfied with the results of the latter mixture especially. Owing to the potato crops being mostly damaged, it is useless to carry out any further experiments this season, but early next season I will continue the experiments, trying other mixtures in addition to those already used. Owing to this season being very dry, the thrip pest was very bad. Should next season be cooler, and the rainfall larger, the damage will be considerably mitigated. I am obliged to Mr. Seymour for the valuable assistance rendered in connexion with the experiments." Prevention and Remedies. Under glass, the thrips are not so difficult to deal with, but out-of-doors the task would appear to be almost an im- possible one. In the early spring of 1909, these pests covered the Cape "Weed when in flower, and extended over thousands of acres of Cape AVeed-infested land. Whole paddocks appeared to be alive with them, so that it would be impossible to destroy them. The best plan of deahng with the pest is to keep a constant watch, and spray regularly with some deterrent, such as quassia chips, and to destroy all affected blooms. The land should be kept well stirred, and the plants kept growing as freely as possible. In small gardens and in 18720. B 34 DESTRUCTIVE INSECTS OF VICTORIA : a;lass houses, the old-fashioned, but wonderfully successful, Gishurst compound is to be highly recommended. Unfor- tunately, in roses, the tiny beasts get right into the centre of the blooms, thus rendering the task of successful spray- ing even with tobacco or kerosene exceedindv difficult. I have great hopes that suitable light canvas covers may be successfully used, as cyanide gas, if applied by an expert, would be the most effective way of dealing with them ; where the most careful spraying would fail bo come in contact with the insects, the gas would be almost instantaneous. Various materials have been recommended for use as mulching, but where it is to be obtained grass hav is the cleanest and best, and is not likely to be scraped away by birds. Stable manure, although most useful and desirable, is a harbour for thrips, flies, and other insects, so that, in rose gardens at any rate, the use of crushed bones would be preferable. In trying to avoid the attacks of thrips, some growers have resorted to blood manure and other pov^'^erful soil stimulants, but with roses especially these must be used with some discretion. In America, the favourite spray for thrips is whale-oil soap, one pound to each gallon of water used, and applied at a temperature of 130 degrees Fahr. According to the California Fruit Grower, the use of lime in the following proportions has been highly recommended : — 35 lbs. of lime to 100 gallons of water. Where requisite, a stronger spray from 50 to 75 lbs. of lime to the 100 gallons of water, was used with the best results. In Victoria, we have had the best results with benzole soap, the preparation suggested by this Branch, and manufactured by Mr. S. Lowe, of Victoria -street, Abbotsford, under the name of " Benzole Emulsion." The thrips question is even now a very serious one, as so large a number of plants are subject to its attacks, and no one knows where the trouble is going to end. It behoves all growers to look this trouble COMMON THRIPS. 35 square in the face, and, if possible, to keep it within reasonable bounds. Only a strict co-operation on the part of the growers, coupled w^ith such advice as can be tendered, can hope to bring about the desired results. Where gardens or orchards are surrounded by Cape Weed or even Hypocharis-infested paddocks, the exclusion of thrips from the gardens would appear to be hopeless, and in such cases smoking out where practicable should be resorted to. When the buds are just bursting is the time for an occasional spraying with a weak material, such as deter- rents, but in the case of roses, when the thrips have once got into the buds, the latter may as well be cut off and burnt, as the blossoms are sure to be a failure. It is pitiful to see the devastation that these tiny beasts will sometimes cause in a rose garden ; still, there are some roses which appear to be much less liable to attack than such kinds as those of the splendid Cochet type, so that future genera- tions may see a hardier type of thrip -resisting roses. . In England, gardeners depend on a liberal use of syringing with water, but here, after a drenching storm of rain, the thrips are as bad as ever. Professor Webster remarks that this pest is increasing rapidly in Ohio (U.S.A.), as extensive onion-growers have recently found out to their cost ; it is a serious obstacle to successful onion culture, especially in dry summers. Onion-growers wi]l therefore need to be on the look-out ; if the pest be noticed, the fact should at once be reported to the Entomologist. B 2 36 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CIV.

FIRE BLIGHT OF THE WATTLE. 37 CHAPTER ex. Fire Blight of the Wattle. {Paropsis orphana, Erichson.) Order : Coleoptem. Family : Chrysonielidoe. This is a small beetle belonging to the large group of leaf feeders. It is light-green in colour, with white stripes or markings. The eggs, which are somewhat spindle- shaped, are laid in clusters on the foliage and tender twigs of the plant. When hatched, the young larvse spread out and crawl over the whole foliage, and, being in vast num- bers, soon commence the work of destruction by eating into the epidermis of the leaves. The latter at once turn a reddish-brown in colour, and when seen from a distance the plantation appears as if a fire had gone through it, hence the common name " Fire Blight." The larvse are stout, and of a dirty green colour, with two pale parallel lines running down the dorsal surface from behind the head to the tip of the abdomen ; and, as they assimilate, both in colour and shape, to the twigs and foliage among which they are feeding, they may easily escape notice by the casual observer. Of all the insect enemies of the wattle industry, this beetle is by far the worst ; and, as the insects are in such enormous numbers, it is almost impossible to deal success- fully with them. I made the first investigation of the life history and habits of this terrible pest. We know that it has a wide geographical range in our State, and is also found in New South Wales and Tasmania. In Vic- toria, my experience has been that the only plants attacked to any extent are the common Black Wattle {Acacia decurrens) and the Silver Wattle {A. dealhata). Although I have repeatedly looked for it, I have never yet seen 38 DESTRUCTIVE INSECTS OF VICTORIA : it on either the Golden Wattle {A. pycnantha) or on any other of the more arborescent, or others of the wattle " family." When I say that I have not found this beetle on any other plants other than the two wattles before mentioned, I mean that I have not seen it in any harmful numbers^an odd beetle or so will when flving alight almost anywhere. As an example of their numbers, I may say that I have shaken off as many as 600 beetles from one small wattle. When the larvae are full grown (in Victoria from about July to January), they descend into the soil, the grubs being at this time of a much lighter green— -almost yellow in colour. When in the soil, usually from 1 to 4 yards from the stem of the tree, and about 2 inches below the surface, they remain until assuming the pupal stage, and, upon emerging from the soil as perfect beetles, climb up the stem of the tree. Here their wing-cases harden, and the function of reproduction at once commences. From my own observations, which have been extensive. I judge that the birds are not partial to the grubs of this beetle, as both larvae and beetles may be seen brawling up and down the stem quite unmolested, either by birds or ants. According to what I have both heard and seen, the stripping of the foliage in such a wholesale manner renders the bark very difficult of removal, and results, owing to constant attacks, in the death of the affected tree. Many trees so attacked will manage to temporarily recover, the principal effect being that the tree becomes what is generally known as " hide-bound." Thus the bark is more difficult to strip, and even when stripped has lost much of its tannic value. It appears very singular that a tree so astringent in its nature should furnish such a palatable food for this pest, although it is well known that some beetles will live upon capsicums, cigars, and on the turpentine-impregnated Coniferoe, such as White Deal, &c. According to my own experience, the beautiful Silver Wattle is mainly responsible FIRE BLIGHT OF THE WATTLE. 39 as a food plaut for caTrying these beetles over the winter, thus keeping them going until the black wattles are sufficiently large to be attacked. Prevention and Remedies. On small areas, such as public parks and gardens, the beetles may be kept off by spraying with some deterrent such as kerosene emulsion or an infusion of quassia chips, but the former-mentioned material, taking into consideration its volatile nature, coupled with the intermittent period of egg-laying, should be frequently renewed. The surest plan of getting rid of these pests is to destroy as many of the perfect insects as possible. This may be done by beating the trees with long poles, and by covering the surface of the ground beneath the tree with lime. I have found, by personal experience, that on small areas of land so treated neither larvse nor pupae will come to maturity. As showing the enormous damage done by this insig- nificant beetle, I may mention the fact of the late Mr. Michaelis, then a well-known merchant of Melbourne, having expended between £30,000 and £40,000 in his endeavour to place the production of wattle bark in its proper place as one of the chief industries of the State. The wattle plantations referred to were planted in the Gippsland Lakes district, and just as things looked flourish- ing for the spirited owner, the " Fire Blight " made its appearance, and, notwithstanding all efforts and experi- ments, in which I gladly assisted, a hopeful commencement was changed into a huge failure. In this case no expense was spared ; spraying, shiploads of Hme, beating, and other means were tried, but the beetles came on in such vast numbers as to baffle all attempts to cope with them. 40 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CV.

This pest is a small beetle about a quarter of an inch in length, with a somewhat V-shaped marking on the wing- cases. The whole appearance of the insect is greyish- brown in colour. The larva or caterpillar is small, of a pea-green colour, and is usually found in the soil a few inches below the surface. When about to pupate, or to change into the chrysalis stage, it constructs a cocoon made of soil (see Figs. X.-XL), where it remains for a couple of months, and emerges as the perfect beetle. This is a new and formidable enemy of the tomato - grower, and was first brought under notice by the Assistant Entomologist, Mr. C. French, jun., who sent the specimens, as being new to him, to Mr. Lea, F.E.S., State Entomolo- gist, Tasmania, who is a specialist in the Curculionidce, or Weevils. The family Curculionidoe embraces several thou- sand species in Australia alone. Mr. Lea found the specimen to be new to science, and has named it as above. The beetle itself is nearly as destructive as the larva, and goes down into the soil in the daytime, coming up at night to feed. The larvae often feed in the daytime, but the perfect insect rarely does so. The genus Desiantha is a fairly large one, and comprises many destructive kinds, some of which gnaw the buds of plum and other fruit trees, frequently destroying a large portion of the crop. Mr. C. French, jun., in an article contributed to the Victorian Journal of Agriculture, says — ^" During the last three months, many specimens of this beetle and its larvae were sent to the Entomological Branch, the persons for- warding them stating that these weevils were destroying 42 DESTRUCTIVE INSECTS OF VICTORIA : large numbers of tomatoes and other plants at Ascot Vale, Essendon, Preston, and other places near Melbourne. These insects are simply in thousands in some gardens, and destroy nearly all kinds of vegetables. One grower, informs me that he lost 80 fine tomato plants in one night, and that on one evening alone he collected no less than 638 of the beetles in the course of an hour, and in a week he estimates he captured and destroyed some thousands. The insects conceal themselves in the soil and debris in the daytime, and at night come out to feed. They devour the whole plant very rapidly, and, should they be disturbed or a light be brought near them, they immediately drop to the ground, and get out of sight as soon as possible." It is very remarkable that this weevil, although in such large numbers, has hitherto been unrecorded, but it is one of those entomological enigmas which are frequently making themselves manifest ; hence the great value of the study of economic entomology. Prevention and Remedies. Some tomatoes sprayed with arsenate of lead were placed in an observation box by Mr. C, French, jun., and 50 of the beetles were liberated and turned adrift into the box. They at once commenced to feed, with the result that they were all dead within 24 hours. As the weevils are in the ground close to the plant during the day, I would advise that the soil be continually turned up, and that fowls be placed in the coops close to the plants. Another good plan would be to hold an expanded umbrella under the plants, giving them a sharp jar or shake, thereby catching the beetles in thousands. They can then be destroyed by burning or scalding. Many of this family of weevils are very tenacious of life, so the water must be boiling or as near to it as possible. Trap crops of anything palatable to the insects should be planted near to the tomatoes, and sprayed with arsenate TOMATO WEEVIL. 43 of lead or Paris green, and by this means large numbers of beetles and larvae will be killed. Another good plan, which has been effectually tested, is the placing of pieces of newspaper under the plants at night, and for the grower to go out at intervals with a light ; the beetles, startled by the light, immediately fall into the paper, and may then be destroyed. These weevils are very partial to the Marsh Mallow, and this otherwise noxious weed might be turned to good account by poisoning the leaves as before stated. The tomato weevil is a prolific breeder, and every possible means should be adopted to prevent its spread. It may be seen throughout the year, and the damage must necessarily be considerable. Growers are warned against spraying with the arsenical preparations such crops as tomatoes, lettuce, cabbage, &c., as vegetables are frequently consumed before being washed thoroughly. In such cases, a weak solution of quassia chips or kerosene emulsion as B, deterrent is to be preferred. 44 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CVI.

The genus Diadoxus, which comprises three species, was formerly known to Victorian entomologists as belonging to the foreign genus Ancyloclieiria. There are but two Victorian species, the one under notice here being much the larger of the two ; the larvae of both live in the wood of the Miirrav pine, and are terribly destructive, also to the Lambert's Cypress {Cupressus Lmnbertiana), the latter being the plant so largely in use for hedges and breakwinds. The males (see Figs. IL and IIL) are smaller than the females, and, as a rule, display greater activity. In small trees the larvae of these insects first feed round the stem under the bark, cutting the sap wood, and causing the tree to snap off. When the Cypress is attacked, the boring is the same as that shown on the plate. The perfect insect, then somewhat soft, emerges from the holes in the side of the tree attacked. The larva is flattened in shape, with the head and thorax part much dilated. A little warmth soon serves to harden the newly-emerged beetles, which soon become verv quick in their movements, especially when walking. The mandibles of the larvae are strong, and well adapted for tunnelling. It has been stated that the Murray Pine is almost immune from insect attacks. Leaving these two beetles out of the question, there are others which are almost peculiar to the Murray Pine timber. When cut, however, it is one of the ver>^ few timbers which the White Ant seems not to be particularly fond of, although it is by no means exempt from the latter pest. 46 DESTRUCTIVE INSECTS OF VICTORIA : Prevention and Remedies. In dealing with matters of this kind, one cannot but recommend a constant vigilance, particularly if the plants are situated in or near Murray Pine country. Should the upper branches, especially, show traces of turning yellow, the trees should be at once examined ; if carefully looked at, tiny holes may be seen, and probably the beetles may be emerging, as shown on the plate (Fig. I.). In such a case, the holes should be probed with wire dipped in bi-sulphide of carbon, leaving the wire in the holes. This could be done by a boy, and would be effective. 48 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CVII. "Small Diadoxus Borer" (Diadoxus erythrurus, White). Fig. I. Larva of Beetle. Enlarged.

White.) Order : Coleoptera. Family : Bwprestidce. This is a pretty but very destructive beetle, whose natural home is in the Murray Pine (Frenela). It is much more common than the large species {D. scalaris), and appears to be more widely distributed. It is by no means certain that either of these is confined strictly to the Coniferoe, both species having been taken where neither the pine nor the cypress grows ; I strongly suspect the Mulga and other of the stunted forms of Acacias to be the hosts of these and other boring beetles. The eggs of this species are deposited in crevices of the bark, and as soon as they are hatched the grubs commence boring their way into the tree. When the full size is attained, they are supposed to remain in the wood for some considerable time, they then change into the pupal stage, and so remain until the final change into the perfect beetle. The larva or grub is yellowish-white in colour, and about half the size of that illustrated. It is singular that when alive these beetles are greenish in colour, and after death they turn yellow. This beetle is found also in New South Wales, South, and Western Australia. Generally speaking, the Diadoxus may be termed dry country beetles, and, although both of the Victorian kinds have frequently been found crawling in the streets of Melbourne and suburbs, they are much more plentiful in the Mallee districts. These beetles are largely responsible for the disappearance of many fine ornamental trees from our streets. Many years ago, the Lambertianas about Mel- bourne were dying out in patches, and the late Mr. Elliott, 50 DESTRUCTIVE INSECTS OF VICTORIA : of the Age staff, and myself, set to work to try and find out the cause. We were successful ; from one large Cupressus we took no less than 37 beetles, besides numbers of larvae and pupse, thus accounting for the trouble. • Apart from the fact that Lambert's C}^ress is the best hedge plant in the State, it is discouraging to find that, in spite of, perhaps, years of careful attention in treating the plants, large gaps of dying plants are seen. These never regain their former condition, even if attended to promptly. Fig. V. gives a fair idea of the damage caused by these insects. Lately, it was rumoured that the beetle had attacked apple trees, but inquiries elicited the fact that a mistake had been made, and for this we are grateful. One thing is certain : These insects are never to be depended upon, and care should be taken that they do not, like many other pests, attack the fruit trees in this State. It is desirable to know as much as possible of the habits of these beetles, so as to save much time and useless experiments. Prevention and Remedies. The treatment is practically the same as that prescribed for the larger Diadoxus ; the principal difference is that where the insects are very bad, affected portions of the trees should, where practicable, be taken away and burnt. Isolated plants should be sprayed with kerosene and other deterrents, but on large areas this would, of course, be out of the question. 52 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CVIIL " Rose and Raspberry Scale " (Diaspis ros^, Sandberg).

Family : Coccidce. Maskell gives the following description : — " Female puparium nearly circular, white, often aggregated in masses, diameter about one-twelfth of an inch. Male puparium white, elongated, carinated, length about one- twentieth of an inch. Adult female a deep-red in colour, elongated, the body deeply segmented. Cephalic region very large, smooth, on each segment of the body several spiny hairs ; five groups of spinnerets, no single spinnerets. Adult male (see Fig. IX.) orange-red in colour ; antennae, ten- jointed, with several hairs on all but the first two joints : feet slender, hairy ; digitules fine hairs. The spike is somewhat long." This well-known and very destructive scale is easily distinguished from most other kinds by the large numbers of flat white scales adhering to the stem of rose bushes, as shown in Fig. I. In Victoria, this scale must have been introduced a long while ago, as it was here in the early fifties ; the probability is that it came on roses from the old country. This is a scale which, if not checked, will spread very rapidly. Newly imported roses when planted out are especially liable to attack. Infested plants soon show the weakening effect on the plant owing to the damage done by the sucking of the juices of the plant through the rostrum or beak of the insect. Hence it happens, as a matter of course, that the application of any fluids to the trees externally, with the object of poison- ing the insects in their feeding, is, as Maskell remarks, useless, as their food is drawn from beneath the surface. 54 DESTRUCTIVE INSECTS OF VICTORIA : It has been said that this scale will also attack the roots of roses. This is not my experience, although I have frequently found it close down to the ground line ; I have banked up the soil for a few inches, but always found that the buried insects made no headway, and under the lens appeared to be sickly and shrinking. Of course, the nature of the soil will have something to do with this; the air would not be freely admitted if it were hea\y and of a sticky nature. In America, Australia, and elsewhere, it has been found that this scale will also attack the stem and the roots of the raspberry, blackberry, and currant. Prevention and Remedies. In places where the scale insect exists, or has been known to exist, a strict watch should be kept, and a preventive, such as a light spraying with a weak, 1 in 30, kerosene emulsion, would be beneficial. This should not be carried out until the foliage has ripened, and should be done carefully and intelligently. In treating roses for scale, the best rule to lay down is to attempt to eradicate it in the winter. Some roses require severe pruning, others light pruning, but all scale-infested prunings should be burnt on the spot, or as near to it as possible, always remembering that it is by means of cuttings or roots of plants that this pest is distributed. When the scale is down near to the surface of the soil, bank up the soil round the stem of the plant to about 3 inches, less in heavy soil, and about once a week fill up with ordinary soap suds. This is easily done, is inexpensive, and, as I have for a number of years proved, entirely effective. It also promotes the growth of the plants themselves. In Victoria, at any rate, the " Dog Rose " stocks do not seem so liable to be attacked as are those roses budded upon other stocks ; and, as every practical rose-grower knows, the so-called hybrid perpetuals are more liable to attack than are the teas and other sections. EOSE AND EASPBERRY SCALE. 55 In the cooler districts of the State, growers of small fruit, such as raspberries, currants, &c., should keep an active look-out for this scale. Should its presence be suspected, the Entomologist should be at once notified, and the case will be promptly attended to. In the mean- while, all affected prunings should be at once burned. 56 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CIX. " She-oak Scale " (Frexchia casuarix^, Maskell). Fig. I.

Family : Coccidoe. This remarkable insect, which is probably one of the most singular in the world, was first brought under scientific notice by the writer. It was found by me on She-oaks, Casuarina quadrivalvus especially, growing on the sea coast at Sandringham and other places not far from Melbourne. Having noticed a number of these fine and beautiful trees either dead or dying, I set to work to ascertain, if possible, the cause. I found nearly the whole of the branches studded with a hard and singular gall, which, upon raising the extinguisher-like cap or covering, disclosed a pink jelly-like animal, as shown in Fig. VII. This was to me a mystery, as I could not conceive it possible that an animal of so frail a texture would do so much damage to trees of a specially hard- wooded nature. There was, however, no doubt as to the real cause having been found, so I sent the specimens, with notes, to the late Mr. Maskell, of New Zealand, the Australasian authority upon scale-insects and their allies. These insects were a puzzle to Mr. Maskell, but he went to work and figured the specimens, naming the genus Frenchia. In later years, Mr. Lea, F.E.S., State Entomologist, Tasmania, obtained living specimens from myself and others, and succeeded in finding out certain important matters connected with the life history of this extra- ordinary insect, and I cannot do better than quote from his able paper on the subject. 58 DESTRUCTIVE INSECTS OF VICTORIA : " Perhaps the most remarkable of all the gall- forming insects are the species of Frenchia, all of which attack the Casuarinas, or She-oaks. There are two species now known, one from Sydney, where it appears to be very rare, the other from Victoria and Tasmania ; the latter species is known as Frenchia casuarina, and frequently kills branches of She-oaks. Its larva3, when young, are in appearance much like those of other members of the family, being provided with three pairs of legs, a pair of compound eyes, and a pair of antennae. After leaving their mother gall, they wander over the bark, and finally settle down. Here they cause galls to form, the galls in time completely covering them. The galls continue to grow, and eventu- ally from the middle of each gall a cylindrical woody growth appears, which may be readily detached. " Meanwhile, changes have been taking place in the insect itself ; it loses its legs, antennae, and eyes, and even its mouth parts (henceforth receiving its nourishment through its skin by the process known as osmosis), and appears as a little brownish object of irregular shape, but having a small node at its lower end, and a sort of thick tail at one side. As growi^h continues, the tail becomes thinner and increases in length, extending almost the whole length of the woody growth ; its bottom also becomes saucer-shaped, but still with the small node which is fitted into a depression in the wood ; it is doubtless at this stage that pairing takes place. Later on, the tail collapses, bends over, and appears fitted to a remarkable cap, which is joined to the body by an irregular suture, much as the sutures of the bones between the human skull. The body itself is now shaped like a wad, and, on removing the cap, the top can be seen to be completely covered by fine concentric rings, with a small opening in the centre, from which the young can be nearly always seen escaping. A heavy coating of white mealy substance is always attached to the wall of the enclosing gall, while the insects are healthy, but when these are attacked by parasites, as SHE-OAK SCALE. 59 is often the case, this substance disappears. When fully fed, the lower portion of the gall is completely filled, and doubtless gives to the insect its peculiar wad-like shape. The trees attacked by these insects are often killed by them, and the galls are frequently to be seen in immense numbers. " Common as the females are, the male has never yet been described, and has probably never been seen, although it has been keenly searched for ; it will probably be much the same, however, as many others of the same family. " Briefly summed up, the life history of this insect, probably the most remarkable in Australia, if not in the whole world, is as follows : — " 1. Born in possession of six legs, two compound eyes, a pair of antennae, and wdth mouth parts. " 2. Attacks bark, and causes compound galls to form. " 3. Gains a tail, but loses its legs, antennae, eyes, and mouth parts ; at this stage completely cut off from the outer air. From now onwards nourished through its skin. " 4. Again changes its shape, tail becomes semi- detached from the body, the upper surface of which is marked by several concentric rings. " 5. Females abundant ; male unknown." It is fortunate for our orchardists that, although this insect must have existed from the earliest times of fruit- growing in Victoria, it has so far never been known to attack fruit trees, or, in fact, introduced trees of any kind whatever. This does not imply, however, that it may not do so, like many other serious pests have done before, as they may find an easier mode of living, viz., on introduced fruit trees. In the earlv davs of Victoria, the coast-line, say from Brighton to Cape Schanck, was thickly studded with She-oak trees, the drooping one (0. quadrivalvis) being the 60 DESTRUCTIVE INSECTS OF VICTORIA. kind which grew nearest the sea ; the more erect species is found more inland. In the early fifties the writer recollects that quite a fleet of small craft was engaged in the firewood trade, with head-quarters at Dromana, at which place, long before a pier was thought of, thousands of tons of this firewood might have been seen stacked for shipment to Melbourne. With the exception of the wattle, the She-oak is the best wood for bakers' purposes available. As a shelter tree for sea-shore purposes, it has no equal, the roots being mostly surface ones, and therefore useful for binding, and arresting erosion caused by the action of wind and wave combined. As a shelter tree, it may be observed that the Casuarina is one of the most valuable, growing with the Wattle in places where little else would thrive, making at once a shelter for stock, being useful as well as ornamental. The hardiness of this insect, as also others of the same group, is shown by the fact that when on the sea-coast they will survive strong winds and salt sprays which are so deadly to most vegetation, and also to soft-bodied insects. Aspi- diotus rossi, a flat black scale, common to Blackwood and others of our native trees, will thrive on coast plants which are at high tide partially submerged by the sea ; and the scale now dealt with is equally hardy, but much more deadly in its effects than are most members of this large and highly interesting group of insects. It must not be sup- posed, however, that this Horn Scale is confined to the coast ; on the contrary, it is common on the She-oaks growing on the wind-swept hills of Myrniong, Black- wood, and other inland parts of the State. As this insect is of such extraordinary interest, especially to naturalists, I have given a more detailed plate than usual. Prevention and Remedies. It has been suggested that this pest will attack only old or full-grown trees. I have proved this to be an erroneous SHE-OAK SCALE. 61 idea, as it will attack plants of Casuarina when these are only 8 or 10 feet in height, so that persons going in for plantations w^ould do well to be on the alert ; a spraying with some cheap deterrent, such as tar water, would most likely prevent the young plants being attacked. As the cultivation of such a valuable commercial timber as the She-oak is sure to be largely extended in the near future, it behoves all to keep a keen lookout ; when a large tree is attacked (I have seen thousands of galls on one tree), there is but little hope of successful treatment. This pest has been found growing plentifully on trees in close proximity to orchards, but, as before stated, it has, so far as we know, kept to the She-oaks — both of the common kinds. Although this is one of the most valuable and handsome of the native trees, it would be well to remove them if found growing near to an orchard, and the same remark would apply to Wattles. 62 DESTRUCTIVE INSECTS OF VICTORIA PLATE ex.

This very destructive pest was first noticed here by myself as having worked havoc with consignments of sweet potatoes which were being sent to Melbourne in great quantities from Queensland. As the plate shows, the tubers are absolutely unfit for food when badly attacked. The beetle responsible for this wholesale destruction is one of the Curculionidoe family, and it is somewhat ant-like in shape ; hence its specific name. The body of the beetle is smooth and shiny, the abdomen being of a beautiful steel-blue colour. The other parts are mostly red-black. The rostrum, or beak, by w^hich the skin of the potato is pierced, is strong for so small an insect, which is wingless. The larva, or grub, is white, and about a quarter of an inch in length, and, as the plate shows, it tunnels into the tubers, rendering them useless. The skin is pierced by the female beetle, and in these punctures the eggs are laid, and the young grubs at once commence to eat into the tubers. As Mr. Tryon remarks, no species belonging to the genus Cylas has so far been recorded as being indigenous to Australia, so that this pest is another bad importation from abroad. In Mr. Tryon's valuable work, he says — " At present (1889), I only know of its occurrence in the East Moreton district of Queensland." But as the sweet potatoes which we discarded here were not from the above district, it is evident that the pest has spread, but to what extent I do not know. When first observed in Victoria, a quick and 64 DESTRUCTIVE INSECTS OF VICTORIA : concerted raid was made on all the shops in the City and suburbs, and, when the pest was found, it was promptly and effectually dealt with ; the prohibition of sweet potatoes from Queensland quickly followed. Prevention and Remedies. As sweet potatoes are not likely to be largely grown in Victoria, although they will thrive in the warm part of the State, it will suffice if I give Mr. Tryon's advice : — " We would suggest that the tubers should be unearthed as a demand for them has arisen, and consumed with as little delay as possible. All the affected ones should be destroyed, or used as food for stock ; also, if practicable, in a district where it manifests itself, all the sweet potatoes raised there should be consumed on the spot, and during the succeeding season no sweet potatoes should be grown." As this pest, like the root borer, is without proper wings, the danger of spreading would be largely minimized ; but it might be spread by other agencies, such as dirty bags in which sweet potatoes have been carried. We have too many pests already, and who knows whether these beetles may not take a fancy to our potato crops ? We must keep a strict watch on these matters, and, above all, when the pest is discovered, act promptly and persistently, as by such means only can the trouble be brought under control or, better still, stamped out. 18720. 66 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CXI.

Family : Ceramhjeidoe. The three species of timber-boring beetles treated in this chapter represent a genus of very handsome though destructive Longicorn (long-horned) beetles, of which there are a good many described from Australia. The beetles, as shown in our plate, are mostly long and narrow in shape. The larvae are fairly active footless grubs. The eggs are deposited in crevices in the bark, and, when hatched, the young larvae commence to bore for their natural food. Haunts of beetles of this genus, and in fact many others of the longicorn family, may be located by the cut-off appearance of the bough (see Fig. II.) ; and the tow-like stopping indicates the presence of the larvae at work in the wood below. * The larvae of the genus Uracanthus are not at all par- ticular as to the kind of trees they attack. They have been found in Acacias, the Giant Helichrysums, in the common introduced Furze or Gorse, and in other plants, both indigenous and introduced. On the fringe of qui sea coasts the larvae of some of these beetles do great damage to the natural shelter trees, particularly to two of the Acacias, viz., A, longifolia and its variety sophora. It is no uncommon sight to find the whole plant riddled with larvae, the sickly appearance of the tree being to observers a sure indication of the trouble going on inside. C 2 68 DESTRUCTFVE INSECTS OF VICTORIA : These beetles, in common with most species of the same family, are night flyers. Upon emerging from the pupa, in a mummy-like form of the perfect beetle, it ascends to the tops of the tree, and there remains until the late twilight, when it takes wing. Although the beetles may appear scarce, they are nevertheless quite common, and are easily attracted by a bright light. The larvae of the large kinds of Uracanthus, at any rate, lie very close in their self- constructed tunnel, and, upon being handled, they become fairly lively, when exposed to either light or air. Fig. IV. shows a species which has lately come to light in Victoria, although it has long been known in South Australia. It is a very pretty and distinct kind. Our plate shows the larva of one of the largest species at work. I have lately received what appears to be a giant species of Uracanthus from the scrubs of semi-tropical Queensland. The longicorn family includes in its ranks some of the largest known beetles, the larvae of which are frequently used by natives as food. A good female specimen of Titanus giganteus from Cayenne will measure at least 9 inches in length of body, so it may be imagined what damage these huge beetles do in the forests of tropical countries. In Victoria, where a deal of timber comes in from many parts of the world, there is a great danger of some of the worst timber-borers being introduced by this means, and several very destructive kinds have already been found in the City. There should, therefore, be constant vigilance by persons familiar with the insects, not only of our own State, but with those of other countries also. Prevention and Remedies. On small areas, kerosene and a little oil of tar mixed sprayed on to young or small trees will keep the female from depositing her eggs, but the spraying wiU of course have to be renewed. The beetles appear from December to April as a rule, so this would be the best time to use the URACANTHUS TIMBER BORERS. 69 preventives. When the trees have been attacked, examine the branches well, and cut off every affected limb, or at least a portion of it, and, as I have before mentioned, a little practice will soon enable any one to locate the larvae at their work. In badly affected districts, a bright lamp placed inside a tent will attract numbers of these night- flying insects, when the captives can ^either be destroyed or kept for the cabinet collection. 70 DESTRUCTIVE INSECTS OF VICTORIA PLATE CXII.

Yellow-box Borers. {Phoracantha tricusfis and P. recurva.) Order : Coleoptera. Family : Ceramhycidoe. These are two of our finest but terribly destructive Longicorn or long-horned beetles. The former, P. tricuspis, is the largest known species of the genus, and the figure, which is life size, shows that it is of a light-brown colour, with a few darker-brown markings on the elytra. The head and thorax are very dark-brown, the latter being much wrinkled. The antennae are of the same colour, and frequently half as long again as the beetle itself. The eggs are deposited in the crevices of the bark, nearly always in the bark of Eucalyptus vmiinalis, a tree formerly very common around Melbourne. The larvae are stout, footless grubs, which bore with rapidity. When in the pupa stage, they assume very much the form of the perfect beetle, but mummy-like. The antennae and legs are stuck in close to the body, the whole being of a yellowish - white colour, and quite soft to the touch. In the early summer, these beetles may be seen emerging from the side of the tree. Here they rest until hardened by exposure, and then ascend the tree, where they remain until night comes on. They are then strong enough to fly, which they do fairly quickly. The male, as in the case of Longicorn beetles generally, is smaller than the female, and usually has longer antennae. The genus Phoracantha comprises a good number of species, and these, together with those of its ally, Tryphocharia, are all more or less destructive to timber. 72 DESTRUCTIVE INSECTS OF VICTORIA : During the last twenty years or so, the trees of E. vimm- alis have largely disappeared, so that many insects, which formerly bred in it, have taken to the Yellow Box {E. rnelliodora), which still exists in fair quantities. Our plate gives a representation of a piece of Yellow Box attacked by these and other insects ; the perfect beetles have already emerged from the timber. Phoracantha recurva is a much smaller insect, but plays great havoc in the wood, mostly in the branches. Mr. Tepper, the veteran entomologi.st of South Australia, remarks that in South Australia this beetle only attacks ring-barked or felled timber. This is certainly not the case in Victoria, as in hot weather I have frequently seen the green branches, when fallen from the tree, with the beetles emerging from the wood. The tunnels are easily recognised by those acquainted with the life-history of Victorian insects. This species may be identified by its long saw- like antennae, which are also strongly spined. Phoraamthas are widely spread, 1 have had the former species from Melbourne to Northern Queensland, whilst the smaller species, P. rerirva, is listed from nearly every known portion of Australia, and is as common in Queens- land, Western Australia, and Northern Territory as it is in Victoria. It is also found in Africa. Both species, and, in fact, most others of this genus, are also to be found hiding under the loose bark of some of the larger gums, such as the Red Gum, Blue Gum, and others. When captured, these beetles make a noise resembling grating or squeaking. On hot sultry summer evenings, both of these species may frequently be seen flying in the twilight, but the nocturnal birds destroy great numbers of these and other night-flying insects. It has always appeared to me strange that so few of our numerous native timber-borers appear to have taken to our fruit trees; one would imagine that the bark of the YELLOW-BOX -BORERS. 78 apple, pear, plum, and other similar fruit trees would be moie palatable than that of the astringent bark of the eucalyfts and acacias. Fortimately, so far as we are aware, neither of these beetles has as yet attacked orchards, or, in fact, any intro- duced trees ; but as the smaller one, at any rate, is common in parts where there are but few if c.ny gum trees in the neighbourhood, it is reasonable to believe that it must breed in one of the Acacias, which plants largely comprise the arboreal vegetation of the more aiid parts of Australia. Prevention and Remedies. As a rule, neither of these two beetles is to be found in saplings, so that a watch should be kept on larger forest trees, and, where the sawdust appears, the parts attacked should if possible be removed. In parts where these occur plentifully, a good many of the perfect beetles, both male and female, may be captured by means of a s-trong light thrown against a blanket or a sheet stretched between the trees or poles. The blankets are best, as the hooked tarsi, or feet, become fastened in the blanket, and hence the beetles are more easily captured, whereas, when calico is used, they simply fly up against it, and, recovering, soon take wing and are off. Our gigantic spider {Voconia) is very destructive to beetles that hide themselves under bark or logs, the numerous wing-cases, legs, and other remains testifying to the slaughter going on. 74 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CXIII.

Rice Weevil. — The first named of these three serious pests is but too well known, and has been well established in all the grain-growing districts of Australia for many years. It causes an immense amoimt of damage to wheat and maize in all parts of New South Wales, but particularly in the North and North-western districts. As Fig. I. shows, the beetle is reddish-brown in colour, with four lighter- coloured spots or blotches on the wing cases. Mr. Froggatt says that the parents sometimes infest maize while in the field, but seldom, if ever, before it is bagged, so that it is in the ill-constructed granary where the damage is done. Experiments conducted by Chitten- den and others prove that the germination for the develop- ment of this egg into a larva, and from that into a beetle, may be retarded for months under certain conditions ; but let the wheat be stored in warm, badly ventilated, or low-roofed grain stores, and the birth and growth of the young beetle are very rapid. Chittenden says it has been estimated that one pair will, in the course of a year, produce 6,000 descendants. In some samples of wheat, after being kept by Mr Froggatt enclosed in screw top jars 76 DESTEUCTIVE INSECTS OF VICTORIA : for twelve months, 970 grains of wheat yielded 460 weevils ; all of these were in the grain in the grub state when it was placed in the jar. These tiny beetles gnaw a hole into the side of the grain, and in this deposit an egg. In some cases, the Jumping Bean, for example, the grub is in the centre of the bean, and only with the aid of the lens can the smallest hole be detected ; hence it happens that the larvae, by some muscular movements, causes the bean to move (jump), and in some parts of the world affords endless amusement. Some years ago a Melbourne firm imported a quantity of Jumping Beans, but as this meant the introduction of a new pest, entomologists did not appreciate them, and the whole were promptly destroyed. The Eice Weevil, unlike the Grain Weevil, can fly, and this fact renders it more formidable. At the present time, it is found in most countries, and will even thrive in the coldest parts of North America, &c. In Victoria, this insect is very plentiful, and, in addition, cargoes of rice and other grain have to be specially watched and inspected, and if found affected treated as recommended in the latter part of the chapter. Grain Weevil. — Regarding this tiny pest, Mr. Froggatt offers the following remarks : — " Though the common brown wheat pest is usually called the Grain Weevil, it is the one described by Linnaeus under the name of Calandra oryzce — that is, the universal pest. This is somewhat of a misnomer, as it is a comparatively rare beetle, without the same powers of flight. It is some- what larger than the former, without the blotches on the wing covers, and the punctures on the thorax deeper and more distinct. In Victoria, this pest is a real scourge in granaries, and appears in enormous numbers." Nutmeg Beetle. — This is another serious pest, and a fitting companion to the two already described. According to Masters, this beetle is a native of Australia, although we have often found it in imported nutmegs. On that NUTMEG BEETLE. 77 account, it has been proclaimed a noxious insect under the Vegetation Diseases Act. This beetle is light-brown in colour, and one of the well-known Anthribid form and peculiar appearance. The Antlirihids from New South Wales and Queensland are usually found on the trunks of dead trees, where they hunt for and devour the small wood-boring beetles that are attracted to the dead twigs, or which breed out of fungi. Doticus pestilans is common in Victoria, and although, as a rule, it attacks apples which are left on the trees after the main crop has been picked, those which are still juicy are also affected. The Nutmeg Beetle requires watching, and all oversea shipments, if found infested, should be treated before the cargo is allowed to go into consumption. Prevention and Remedies. There would appear to be no better plan than keeping the grain and nutmegs in properly constructed mills or stores. Even then, no matter how careful the owner may be, weevils and beetles of similar habits manage to find their way into most stores. To overcome the pest, the bi-sulphide of carbon treatment has been adopted. In the large granaries of the United States, as Chittenden and others tell us, the material to be treated is heaped upon the floor. A tube or cylinder is pressed down to the centre of the mass, and into this the bi-sulphide of carbon i& poured ; a canvas cover is then thrown over the lot for about 24 hours. This material must be used with care, as it is highly explosive. When used at close quarters and for any length of time, severe headaches, as I have frequently experienced, follow In designing a place for treating grain with this material, provision should be made whereby the doors may open inwards. After treating grain, the door should be thrown open for at least an hour before any one enters the building, so as to allow the fumes to escape. 78 DESTRUCTIVE INSECTS OF VICTORIA : Experiments have been carried out in America to ascer- tain the action of bi-siilphide of carbon upon the germina- tion of wheat, and it has been proved that it can be exposed for 36 hours without injury; and for 24 hours without spoiling it for milling purposes. One pound of bi-sulphide of carbon costs in Melbourne about sixpence, and this quantity is sufficient to treat about 100 bushels of grain. In America, where the carbon is cheaper, it has been estimated that, in a close building, 1,000 cubic feet of space costs ten cents, so that 1 ton of wheat can be fumigated for ten cents. In India, it has been proved that bi-sulphide of carbon is a perfect preventive against weevils in grain ; that its action lasts, if the building be hermetically closed, six weeks, after which period a fresh charge of the agent is required ; that, even in samples which have been attacked by weevils, the effect of bi- sulphide of carbon is immediately felt, the weevils disap- pearing in masses. This chemical does no harm to grain as regards its colour, smell, and cooking properties. Mr. Froggatt, in one of his reports, states that several millers have informed him that, if the bags of grain or flour are stood on end when stacked, they resist the attacks of all pests much better than if stacked on the flat. It is also a well-known fact that if clean grain is placed in a salt bafy, no weevil will infest it. The question then arises, could not the corn sacks be dipped in brine and dried before being used in the harvest field. The cost would not be much, and, though the salted corn sacks might be liable to absorb a certain amount of moisture from the atmosphere, it would not be sufflcient to injure the grain enclosed. \- For treating both zoological and botanical specimens which have been attacked by this pest, the carbon bi- sulphide is an excellent remedy, and for painting dried specimens of plants in a herbarium formalin is now preferred to the corrosive sublimate (bi-chloride of mercury) so largely in use in the herbaria of Europe and elsewhere. 80 DESTRUCTIVE INSECTS OF VICTORIA PLATE CXIV. *' Curved Wing-case Timber Borer " (Platypus cupulatus, Chp.).

Curved Wing-case Timber Borer. {Platypus cupulatus, Clip.) Order : Coleoptera. Family : Scolytidce. This tiny but destructive insect has been found by my Assistant, Mr. C. French, jun., in timber imported into Victoria for furniture making. The logs are taken to the timber yards, and often stacked amongst other timbers. As the plate shows, this beetle is a very small one, with the terminal parts of its el}i;ra or wing cases in-curved (see Figs. V. and VI.). The timber illustrated is a portion of a log sent from the Malay Peninsula. Importations from this and other places in the East are a distinct menace to our timber yards, as there is a grave danger of the pest spreading to other timbers, and also to furniture, public buildings, shipping, &c. The family Scolytidw, to which this beetle belongs, embraces some of our very worst timber-boring insects ; and in Europe the splendid avenues of elm trees have frequently been destroyed by the well-known Scolytus destructor. The method of attack of the pest has been well described by the celebrated naturalists, Andouin and Spence — " .... both the male and female insects attack the tree for the purpose of obtaining food, burrowing into the trunk. This brings the tree to a state of ill-health, which is adapted for the reception of the eggs and for food for the larvae. The female insect then burrows into the trunk, and there deposits her eggs ; and the larvae when hatched form cylindrical galleries, diverging at right angles from the trunk of the parent, and parallel to each other, within which they also become pupae, and so great is the fecundity of these insects that their countless numbers are soon sufficient to destroy the largest tree." 82 DESTRUCTIVE INSECTS OF VICTORIA : The larvae, or grubs, although small, play great havoc with the timbers. This family of beetles is closely allied to the so-called Weevils or Curculionidoe ; and are fairly numerous in tropical countries, where they do damage, not only to timber when growing, but also to joists and beams in houses and to furniture. I am indebted to Messrs. Lea and Froggatt for data in connexion with this pest. In Masters' catalogue of Australian beetles, 3 species are listed, but some of these may be importations from the East. Dejean gives 24 species from the tropics, but at the present date 100 species must be nearer the mark. Prevention and Remedies. All timbers coming here, especially from the East, should be carefully examined by an entomologist, before being permitted to be removed from the wharfs. Upon the first signs of the existence of the pest, the timber should be " held up " for treatment. Spraying with corrosive sublimate, carbolic acid, pre- servative oil, or other such material, will be efiective. In cases of small consignments, fumigation with cyanide of potassium in gas form or bi-sulphide of carbon may be resorted to. Timber which is too far gone to treat success- fully should be at once rejected. We cannot be too careful in regard to foreign shipments, as, once the pests are introduced, they usually come to stay. 84 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CXV.

LESSER DRIED FRUIT MOTH. 85 CHAPTER CXXI. Lesser Dried Fruit Moth. {Plodia inter functella, Hb.) Order : Lepidoptera. Family : Pyralidce. This very destructive moth belongs to the well-known group of Pyrales, which includes most of those doing damage to cereals, fruits, &c., when in the prepared state. Dr. L. 0. Howard, Chief Entomologist of the United States, and Mr. Chittenden, also of the Entomological Staff of the same country, state that " the adult moth has a wing expanse of between half and three- quarters of an inch. The outer two -thirds of the fore wings are reddish-brown (see Fig. V.), with a coppery lustre. The inner portion and the hind wings are a light dirty-grey in colour, being whitish, with light-rose, yel- lowish, and greenish tints. The pupa is light-brown in colour." " The eggs are minute, and white, and are deposited to the number of 350, singly and in groups of from three to a dozen or more, upon whatever substance the female may see fit to select for the sustenance of her offspring. They hatch in about four days, and in four or more weeks another brood is produced. In this manner, a succession of generations appears. According to the temperature of the building which the insect inhabits, these will vary from four to possibly six or seven a year. The caterpillars spin a certain amount of silk as they feed, joining together particles of their food and excrement, and thus injuring several times the amount of material they consume. When fully matured, they crawl hither and thither, trailing large quantities of their silken threads after them in their search for a suitable place for their transformation ; and finally surround themselves in a cylindrical silken web, in which they change to chrysalids and then to moths." 86 DESTRUCTIVE INSECTS OF VICTORIA : This pest is common throughout Australia, and in Victoria it has given no end of trouble, the larvae having been found in boxes of dried fruits, apples, peaches, apricots, figs, and prunes. It also breeds in walnuts, almonds, and seeds of various kinds, and especially in flour and grain. In our plate we have endeavoured to give some faint idea of the damage done to dried almonds, the specimens from which the drawings have been made being taken from both imported and locally-grown products. As showing the amount of damage which these insects have done to wheat, Mr. Froggatt states — " It has been bred in great numbers from a sample of wheat sent to me by the late James Stephenson (Secretary of the Board of Exports), with a note that 1,000 bags had been shipped to London, and that the wheat was said to have been grown at Coolamon, but there was some doubt about the exact locality. Soon after it had been placed in a jar, it was swarming with caterpillars, and the contents of the jar became so matted together with the silken filaments that they could be lifted out in an almost solid mass, and, on examination, fully 90 per cent, of the grains were found to have the end containing the embryo eaten out. Num- bers of the larvae were found in bran, and others in a box of dried raisins." Mr. Froggatt states that in America it is called " The Indian Meal Moth," though even there it feeds upon all kinds of dried foods. Prevention and Remedies. Cleanliness in the store or factory, and a constant over- hauling of the grain or dried fruits therein stored, would appear to be the best of preventive measures. Should the pest obtain a foothold, treating by either the excessive temperature process, or by a thorough fumigation, com- bined with a careful culling out of all the afiected grain or fruit, seems to be the only successful methods so far LESSER DRIED FRUIT MOTH. 87 devised. In another chapter I have alluded to the very successful bi-sulphide of carbon treatment practised in the larger granaries and dried fruit stores, in the United States and elsewhere. This insect is another of the curses introduced into the Commonwealth, and emphasizes the necessity for careful examination at the port of entry and the adoption of stringent measures. It is hardly necessary to point out to my readers the importance of the great cereal and dried fruit industries in Victoria, and this must be my excuse for the strong wording of the advice here tendered. In the United States the losses occasioned by this insect have been enormous, but by adopting sensible precautions the losses of former years have now been considerably lessened. 88 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CXVI.

Family : Coccidce. The genus Eriococcus, to which E. coriaceus belongs, is but too well known to those accustomed to the forests of our State, and it has a wide range. Eriococcus was first described by the late Mr. Maskell in the Transactions of the New Zealand Institute, 1892, from specimens supplied to him by the late Mr. Olliff, Entomologist, of Sydney, The adult female, as Maskell describes it, is enclosed in an elongated sac of whitish or yellowish cotton ; the body is elongated, segmented ; anal tubercles conspicuous ; feet and antennae present ; several rows of conical spines on dorsal surface ; antennae of six joints. I have never seen the male, but in other species the adult male is a tiny fly-like insect, with hyaline wings, and, according to Comstock, with a pair of long, waxy filaments projecting from the posterior portion of the abdomen. These filaments are very conspicuous, and are whiter and longer than the body of the insect. In the Agricultural Gazette of New South Wales, 1900, Mr. Froggatt gives an excellent account of this scale, as observed by him in New South Wales and elsewhere. It is generally found on young gum saplings that spring up when the larger trees have been cut down. It does not ^0 DESTRUCTIVE INSECTS OF VICTORIA : confine its attacks to one species of Eucalypt, being found upon at least half-a-dozen. This scale has never yet been found on orchard trees, with the exception of a guava and a myrtle in a nursery ; and, as both of these belong to the same family, it is still more remarkable how this insect collects its food plant. This scale may be found more or less in the bush all the year round, but is most plentiful about the middle of October and November. The larvae vary in colour from yellowish to dull-red, are very small and active, and as soon as they are hatched out they crawl over the twigs till they find a hiding pla.ce. The full-grown female coccid is enclosed in a rounded, thick, felted, cotton sac, varying in colour from white to creamy-yellow, dark- orange, or even dull-red, attached to the bark at the base, with the apex opening out into a rounded orifice closed below at the tip of the abdomen, which lies level with the opening. These cottony sacs are closely packed against each other, so that the whole stem is frequently covered for inches right round. Though these sacs are naturally of the above colours, they are frequently smothered with fumagine, caused by the honey dew or superfluous juice of the plant. This they suck up in such quantities that they cannot retain it, but discharge it in the form of a fine spray, which, falling on the bark and foliage, forms a food for the smutty fumagine, the minute spores of which cover it and soon change it into a black skin. Each of these little egg-like sacs contains a female, which is capable of laying several hundreds of eggs ; these soon produce larvae, further covering the infested tree. Although this scale was only described by Mr. Maskell in 1892, it was well known in Victoria in the early days, the late Fraser Crawford and Mr. Tepper having paid considerable attention to it. It was photographed by Mr. Crawford as Eriococcus eucalypti, a most appropriate specific name. In the early fifties I first saw it in the COMMON GUM SCALE. 91 Moorabbin district, and since that time I have seen it ia nearly every portion of Victoria which I have visited. In most cases of scale insects, a vigorous growth will enable the affected plant to at any rate partly resist the attack, but with this scale it is different, as I have seen young saplings of Blue Gum, E. globulus, which were at the time making extraordinary growth, killed right out. The insects are in such vast numbers that spraying and other means adopted have but little effect upon them. In the Victorian bush, at any rate, the plants selected for attack are saplings of almost every kind of Eucalypt, and I have seen it both on the leathery foliage of E. alpina, also upon the Snow Gums at the Alps, where for several months of the year snow reigns supreme. In the Alpine regions of the State this scale does not appear to make much headway, which fact may be accounted for by the tough foliage of some of the Eucalypts in those places, and the effects of the freezing and the snow combined. In New Zealand, this pest, which had probably been introduced from either Victoria or Tasmania, bade fair to put an end to the newly-made plantations of Blue Gums and other Eucalypts, and the situation may be described in Mr. Kirk's own words : — " The appearance of an affected plantation was most uninviting. All the small saplings were completely covered with dense masses of the female sacs tightly packed together, and the smaller branches of the larger trees were similarly affected, while the large amount of honey dew excreted by the insects was responsible for a great quantity of black fungus, probably Fumago vagens, which covered the boles and leaves of the trees with a dense, black, sooty envelope. It was quite impossible to walk through a plantation without one's clothes being stained with the dark-coloured juice of the female sac, which was exuded whenever a sac was touched or brushed against. On all 92 DESTRUCTIVE INSECTS OF VICTORIA: sides the trees, both large and small, were dying in large numbers. Those trees which were not actually killed by the millions of little pumps that were sucking out the life sap of the trees, were greatly weakened, and the lack of sap in the tissues had the effect of cracking the bark in an abnormal manner. Thus the frosts of the winter were able to complete the destruction wrought by the scale. Large numbers of the trees were thus winter-killed, a condition that would not have been present had not the scale been at work. In plantations that had been badly affected, the tall gaunt dead boles of the trees were the only sight that met the eye. The only use that these dead trees could be put to was for firewood, as numerous wood fungi soon put in an appearance, and rendered the timber valueless for fencing and scaffolding purposes." The round Black Scale {Aspiodotus Rossi), a very common native pest, has not so far attacked fruit trees, Olives excepted. This scale has a singular life history, as I have found it on the well-known pine-leaved native shrub {Ricinocarpus pinifolius), a plant belonging to the Euphor- hiaceoe, which one would imagine to be palatable to insects of any kind. A singular fact, which was first brought under the notice of Mr. Maskell by me, was its ability to adapt its shape to the food plant upon which it was sub- sisting. On one occasion I found it upon Ricinocarpus, and its altered form exactly fitted the wire- shaped stem and branches of the plant, so that the scales, instead of being nearly round, as in the normal state, were of a long, narrow, oval shape, and of the same colour as the leaf stems, viz., of a reddish colour. This singular fact in the life history of A. Rossi is recorded in the Transactions of the New Zealand Institute. Prevention and Remedies. In Victoria, the bush fires, although terrible in their visitations, are the chief cause of keeping this formidable pest in check, as the flames sweep rapidly through the COMMON GUM SCALE. 93 undergrowth of gum saplings, killing out all badly-infested plants, together with the scale attacking them. Large trees of Messmate, Stringybark, and Peppermint, on account of the loose stringy nature of their bark, suffer severely ; but generally those of the smooth bark kinds, such as the Blue Gum and the Giant Gum, escape with a severe scorching, and in most cases will be but little the worse for the fiery ordeal through which they have passed. This is shown by the enormous size of some of our monarchs of 1;he forest, which, if they had been greatly affected by the periodical fires of many years, would have long since perished. Where plantations are contemplated, a sharp watch should be kept for the first indications of the presence of this scale, as it increases with an almost incredible rapidity. In small places, a few sprayings with a strong kerosene emulsion will usually be effective ; but where the -scale has obtained a good footing and densely encloses the branches, it will be found that the usual chemical treat- ment will be of very little use. All seedlings before being planted should be examined by an expert who has an eye trained for the work, and any plant showing the least sign of being affected should be rejected and burnt. In New Zealand, Mr. Kirk says that, since the initial distribution of the Rhizohius beetle, the work accomplished by this insect is little short of marvellous, and through its means Eriococcus has been relegated to a position of insignificance in the gum plantations of the south. In all parts of the affected area the scale is being rapidly eaten out, and around Timaru, the original centre of infection, it has entirely disappeared, the rapidity with which Rhizo- hius has multiplied being almost incredible. In January of 1908, his assistant collected over 1,300 scales on ten gum trees at Rolleston in a little over three hours. Thus the numbers in a large plantation are almost beyond the imagination. " In Australia, the balance of power is even 94 DESTRUCTIVE INSECTS OF VICTORIA : between the ladybird and the blight, and both of them are always present ; but in New Zealand the ladybird, being as it were in pure cultures and undisturbed by the presence of any secondary parasites, is much more powerful than the scale, and it completely wipes out the latter. It is not too much to say that within another twelve months there will scarcely be a living scale found on the southern plantations, which only three years ago were swarming with the pest, and to all appearances doomed to utter destruction." The above is a most satisfactory state of affairs so far as New Zealand is concerned, but in Australia the con- ditions are, of course, very different, as in most of our Victorian forests, at any rate. Gum Trees {Eucalypts) largely predominate, and in some parts of the State the arboreal vegetation is composed of but very little else ; whereas in New Zealand the number of Eucalypts is very limited, and are, of course, introduced from Australia and Tasmania. So it happens that, although both the Rhizo- hius and Crypoloemus are indigenous to the State, the close proximity of our plantations to infested forests consider- ably reduces the valuable work of these parasites. The plate shows nearly the whole life history of this pest,, together with some of the parasites, especially the valuable little beetle Orcus, also cocoon of Scale-destroying Moth, Thalpochares. Many years ago, a friend and myself con- ceived the idea that the cochineal-like dye from these insects might be put to some commercial use, but the advent of the aniline dyes quite upset our well-intended project. Upon examining a badly-infested gum branch, especially when the same has grown in a natural forest, large quantities of the sacs will be found to have been quite destroyed by parasites of many kinds, but it i& evident to any unprejudiced person that in Victoria, at any rate, parasites are no match for the scale, although the former help materially in keeping it and other scales COMMON GUM SCALE. 95 somewhat in check. Fortunately, this pest has never been known to attack ordinary fruit trees, but too much de- pendence must not be placed on the present forbearance of this formidable insect. The Eucalyptus scale under notice is foujtid over nearly the whole of Australia, and, as stated, is subject to the attacks of several parasites. 96 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CXVII.

This is a very handsome beetle, the larvee of which feed on the wood of the Yellow Box, and frequently also on the wood of the White Gum {E. Stuartiana). The eggs are deposited either upon or in crevices of the bark, and, when hatched, commence to feed and bore into the wood. It is quite certain, however, that the breeding place of this insect is not confined to the two trees mentioned, as it has been taken where neither of these two Eucalypts is known to grow. The larva is of a dull, yellowish- white colour, and somewhat unusually tapers slightly at the extreme end. The female (see Fig. IV.) is reddish- brown in colour, and altogether a much larger insect than the male, which is black, with beautiful feather-like antennae (see Fig. III.). The pupa, which is shown on Fig. II., is soft and mummy-like, but is soon hardened on exposure to the weather. In Victoria, at least, this destructive beetle is considered somewhat of a rarity, but in reality, and as the timber shows, it is but too plentiful. The reason of its apparent rarity is that as soon as the beetles are sufficiently strong to crawl they ascend to the tops of the trees. It is sup- posed that this beetle is a night-flier, but both sexes have been frequently found feeding in the flowers of the Leptos- permum bushes, especially on very hot days. In some parts of New South AVales it appears to be more commonly met with, and, although it is so destructive, it is eagerly 18720. i> 98 DESTRUCTIVE INSECTS OF VICTORIA : sought after by collectors. The genus is an Australian one, and comprises a fair number of species, nearly all of which, in the summer, frequent the flowers of Bursaria. Leptospernium, &c. Prevention and Remedies. I am indebted to Mr. Giles, late of Nar-nar-goon, Vic- toria, for having first brought the breeding place of this beetle under my notice, he having reared them from the Yellow Box, also from the stunted plant of E. Stuartiana growing in the vicinity. It would appear that saplings are seldom attacked, and, although there are many orchards in the district, it has never so far been known to attack fruit trees. In forests, all the dead and dying branches should, where possible, be sawn away and burnt, so as to kill any larvae or beetles which may be in the affected wood ; the grubs remain for a long time in the wood before they reach the perfect stage, and, as both the male and female are strong fliers, they may soon spread to distant plantations. This beetle is also found in New South Wales, and, occasionally, in the Southern parts of Queensland. D 2 100 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CXVIII.

Family : Coccidce. , This singular scale insect was first sent to me from Wentworth, New South Wales, where at the time it was making great havoc among the Saltbtishes (Atriplex), and bade fair to wipe out these valuable fodder plants of the squatter and grazier. The first known specimens submitted for scientific investigation were sent by myself to my friend, the late Mr. Maskell, who at the time was our leading specialist on scale insects. Mr. Maskell was at work on Australia]! Coccidoe, and found the scale to be a new one of very peculiar features, and, after a careful examination, it w^as placed in the genus Signoretia, so named on account of the well-known writer on scale insects. The species name of Atriflicis, after the plants on which the insects were first discovered, was bestowed on it by the late Mr. Olliff, then Entomologist to the Department of Agriculture of New South Wales. On further critical examination, the genus Signoretia was in this case discarded by Mr. Maskell, and the name given by Olliff allowed to stand. Mr. Maskell also mentions a variety of this species which was sent to him by the late Mr. Eraser Crawford, of Adelaide, and also by myself, as having been found on the Murray Pines {Frenela), and this insect has been named as a variety {spinosa). When I first received the specimens from Wentworth, they were described as rapidly destroying the saltbushes in that and the outlying districts. As this scale is of so 102 DESTRUCTIVE INSECTS OF VICTORIA : destructive a nature, and owing to the close proximity of Wentworth to Mildura and other of our Murray districts, the pest is not unlikely to cross the river into our State. The report of the late Mr. Olliff, who w^as sent by his Department on a special mission to the infested districts, at which places he collected some most important facts connected with the life history of the insect under notice, is interesting. He says : — " The scale insect here figured has recently been foutid doing an immense amount of damage to the various kinds of saltbushes, particularly to the plants known as Rhagodia hastata and Atriflex nummularia at Wentworth, in the western district of New South AVales. Immense numbers of these valuable fodder plants have for some time been dying in this locality. An investigation that I made during the past month proved that the trouble was due to the presence of a large scale insect, which on subsequent examination was found to be a new species of Pulvinaria, a genus of Coccidae, in which the adult females construct a conspicuous cottony covering for their eggs, technically called an oversac, at the period of gestation. " This insect was first observed and forwarded, to Sydney by Mr. D. A. Morgan, Inspector of Stock at Wentworth, and at the time of my visit the oversacs, each containing thousands of minute brownish-red eggs, w^ere found in vast numbers on almost every saltbush, over large areas of country. Many of the bushes were literally covered with the scale, and appeared when viewed from a distance as if they had in some unaccountable way burst in masses of intense white flowers. On one small plant alone I counted more than sixteen thousand of these oversacs, a number that must indicate an almost incalculable quantity of eggs. " The fully-grown female is an active naked insect, measuring less than a quarter of an inch in length, and it is not until the insect fixes itself firmly to a twig of its food SALTBUSH SCALE. 103 plant for the purpose of laying its eggs that the cottony oversac is developed. This cottony or waxy scale com- pletely envelops the eggs, which are further protected by the dead and dry body of the mother scale, which forms a sort of cap to the oversac, remaining firmly attached to its lower end. In this respect the Saltbush Scale resembles the well-known Fluted or Cottony Cushion Scale {Icerya purchasi), although the two insects belong to separate genera that differ greatly in structure and habits. In September, the eggs of the Pulvinaria or Saltbush Scale were beginning to hatch between the cottony sacs, and the young larvae, minute, active, six- legged creatures, with six-jointed antennae, and two long anal setae, soon make their w^ay to the young and tender shoots of their food plant." Prevention and Remedies. As this pest will most likely reach our State through the agency of birds and other means, it behoves us to be careful. The plants growing on the Victorian side of the river should be occasionally examined, and the matter at once reported if any outbreak should occur. Under the conditions in which this pest seems to thrive best, it would appear that, owing to the large areas affected, the ordinary treatment, spraying with a deterrent or a remedial mixture, is practically out of the question. It is therefore advisable to await the advent of natural enemies in sufficient quantities and at the proper time. The best way would be to pull up and burn as many of the affected plants as possible, as the increase of these insects is so rapid that one badly-infested plant will speedily insure the immediate infestation of all plants growing in the vicinity. As Mr. Olliff remarks, " One thing cannot be insisted on too strongly, and that is the absolute neces- sity for immediate destruction of the pest wherever it is found in limited patches. I venture to think that this 104 DESTRUCTIVE INSECTS OF VICTORIA : a duty which every grazier owes to his neighbour as well as to himself, for, when the scale makes its appearance on a run for the first time, no trouble or expense should be spared until it is stamped out," There is no doubt that on isolated patches a non- poisonous spray, such as kerosene emulsion, might be used with much advantage, and in some cases the same treatment would be cheap and effective when used as a deterrent. Those of us who know the graziers' stand-by in the summer, the Saltbush, will appreciate the advice as to immediate action being taken so as to prevent, if possible, the pest from getting a foothold on their properties. 106 DESTRUCTIVE INSECTS OF VICTORIA : PLATE CXIX.

This is a very handsome but destructive beetle, first found in Southern Queensland, and described by the late Mr. Pascoe in 1865. In Master's Catalogue of Australian Coleoptera, two other species of this genus are listed, one being a native of Victoria. Fig. IV. shows the beetle in its natural size, and Fig. VII. the larva ; I regret being unable to include the pupae, as we were unable to obtain specimens, although both larvae and the beetles were in quantities. This pest was first brought under my notice by my Assistant, Mr. C. French, jun., who describes the working as follows : — " These weevils are found in logs of Silkv Oak {Grevillea robusta) and in Queensland Kauri {Dam- mara) logs imported into Victoria from Queensland. The eggs are deposited in the bark, and when the larvae hatch they at once commence to bore through the bark into the hard wood, where they remain for some considerable time. They eat out a hole about 1 inch in depth, and cover it over with pieces of wood eaten out of the hole made. Fig. III. shows a hole covered with the eaten wood, and Fig. I. a hole after the timber has been removed. Fig. II. shows where the insects, when fully grown, have eaten their wav out of the cocoon-like covering, and Fig. III. the bark where the beetles had come through when they were fully grown. Most of the imported timber referred to goes to the Newport Railway Workshops, where, owing to 108 DESTRUCTIVE INSECTS OF VICTORIA : the prevalence of wood-boring insects, all timber is carefully inspected. Should any be found, the timber is treated with various chemicals." It may with safety be asserted that the depredations of this beetle will not be confined to the two valuable timbers in question, so we cannot be too careful. Of late years, the Silky Oak has come into great prominence for furniture, fittings, picture-frames, &c. AVith proper protection, and with judicious selection, this tree should be one of the most valuable timber assets of the Commonwealth. Prevention and Remedies. All timbers coming into Victoria should be critically examined by an entomological expert. "Where valuable timbers, say for carriage building and for the better class of furniture, are imported, these should be strictly quaran- tined in suitable buildings, detached, if possible, from factories and carpenters' shops. Chemical treatment of affected timber, if it is to be effectual, must be done very carefully, and at such intervals as would be justified by circumstances. Fortunately, this beetle is not difficult of detection ; but as the newly-hatched larvse may be at work inside and out of sight, it follows that it would require a trained eye to detect the trouble. It would also be advisable for the timber to be examined by a competent person at the port of shipment, as the use of affected timber may lead to most serious results. no DESTRUCTIVE INSECTS OF VICTORIA; PLATE CXX.

Order : Hemiptera. Family : Coccidoe. This formidable pest of the vine, the largest of the hard- shelled scales I know of, was first brought under my notice by the late Mr. George Neilson, the well-known horti- culturist and fruit expert, and was found by him on some vines growing at Hawthorn, Victoria. Heroic measures were at once resorted to ; the tree was hard-pruned, the cuttings burned, and the remaining portion of the plant sprayed with hot resin compound and a strong kerosene emulsion. This severe treatment evidenth' had the effect of arresting for the time the spread of this gigantic scale, but its presence was soon reported from other localities. It would be interesting to know by what means it was introduced into our State ; as in all viticulturrJ matters the greatest care has been taken, it could hardly have been through the agency of vines or their cuttings. It is now well known that this scale is not restricted to vines, and it has been found on shrubs and climbing plants of several kinds, but, so far as I am aware, not on fruit trees. Judging from the specific name of this pest, the " Barberry " (Berberis) must have been its host plant, but of this I am not certain. That this scale is on the increase there is no doubt, but as it is so large it is easily seen, and steps can at once be taken for its eradication. 112 DESTRUCTIVE INSECTS OF VICTORIA : Prevention and Remedies. If the large scales are lifted up with the edge of a pen-knife, it will be observed that numbers of tiny, soft insects are moving about underneath the tortoise-shaped shell of the female scale. This is the time to attack them with the sprav pump. Cut away and burn as much of the old wood as possible, and then with a brush well scrub the stem with hot kerosene emulsion — one part of the emulsion to five parts of water. Spray the weaker portions of the plant with kerosene emulsion — one part of the emulsion to ten of water. Clear away the soil from the base of the stem, scrape off and burn all old loose bark, and spread a little lime on the ground close round the stem. This pest can be got rid of more easily than many others of the same group, but it must be watched, as also must shrubs and climbers growing in the same garden. AVhen treating vines, be careful that any insects clustering round the newly-cut branches are at once destroyed, as when first hatched the young scale are somewhat difficult of detec- tion, and may have to be carefully looked for. Parasites, small wasps, &c., have been seen hovering about scale-infested vines ; but these must not be waited for. A good spray pump will save the situation. 114 DESTRUCTIVE INSECTS OF VICTORIA: PLATE CXXI. " She-oak Root Borer " (Stigmodera heros, Gehin.). Fig. I. Tea Tree {Melaleuca uncinata). Natural size.

The so-called Laughing Jackass is so familiar to Aus- tralians that a description is hardly necessary. It is well-known as a destroyer of lizards, young snakes, and small birds. It is also partial to chickens, and especially to young turkeys, which it kills by a smart peck on the back of the head. The Laughing Jackass is also known as a Kingfisher ; why, I could never ascertain, as it does not fish, unless it be that it belongs to the same sub-order of birds as the Azure Kingfisher, which is one of the prettiest of our native birds. The Kookaburra is another name by which this quaint - looking bird is known. The adult bird, as Mr. Campbell describes, is about 18 inches in length, including tail 5 J inches, and bill 3 inches. It has a dusky back and wings, some part of the wings being relieved with markings of blue ; the tail is brownish, and barred with black. The eggs, which are white, and three to four in a clutch, are usually deposited in the spout of a limb, but more frequently in a hole in the butt of the tree, and not ver^' high, as a rule, from the ground. The young are fluffy little chaps, and make a great noise, which frequently betrays their otherwise secure whereabouts. The eggs are generally not difficult to find, and the egg robber may pursue his calling with safety, whereas had it been, say, a Black-cheeked Falcon, the nest would not have been robbed without a vigorous protest on the part of the birds , both male and female. 148 DESTRUCTIVE INSECTS OF VICTORIA : Despite the fact of this bird being a terror to the poultry housewife, it is a general favourite, and the farmer, when ploughing, is frequently followed by these birds, which pick-up the grubs as the latter are turned out b}' the plough. They are voracious feeders, and will gorge on grubs until they are hardly able to fly, and in such cases they will hop on to a fence, and, if they are not too much surfeited with food, will usually " laugh " for several moments at a stretch. When perched upon a limb, with a lizard or some other food between its claws, it has a singularly knowing look. The Giant Kingfisher is a capital mouser, and when in confinement will soon leave but few mice about the place. Sparrows, too, are frequently taken, especially wlien barely able to fly, the older birds being as a rule too wary for our Kingfisher friend. It is very amusing to see one of these birds, high up on the outstretched branch of a tree, banging a lizard against the limb until the life is knocked out of the unfortunate prey, which is then swallowed whole. It makes a good pet bird for the garden, and, when not injured and able to get about, even the persistent sparrow gives it a wide berth. The Giant Kingfisher is found over the whole of Australia. fi I i 23 WHITE-BACKED MAGPIE OR CROW SHRIKE. 149 CHAPTER CXXXVIII. White-backed Magpie or Crow Shrike. {Gymnorhina leuconota, Gould.) The White-backed Magpie or Crow Shrike is a fearless, aggressive, but easily domesticated bird, and is a great destroyer of underground grubs, locusts, grasshoppers, &c. A ver}' long experience of this bird, and also with the black-backed species, has convinced me that, as a rule, the farmer can well afford to take these fine birds under his special protection. Their grain-eating propensities are well known, and the old-time clapper formerly used for frightening these birds, as well as parrots and sulphur- crested cockatoos, from the crops is still in the memory of the writer. Both of the magpies are so well known to most that our plate of one of them may be considered sufficient, the economy of both being much alike. It is a singular fact, noticed by many observers, that there would appear to be a line of geographical demarcation between the habits of these two valuable insect-destroying birds. The white-backed species is found mostly south of the Dividing Range, while the black-backed one is found north of these moun- tains. Both are equally bold, resolute, and aggressive, and, though highly recommended as pets, the writer cannot agree with all that has been stated as to their qualifications in this respect, more especially in cases where young children are concerned. The note of the Magpie is simply delightful, and is one of the many pleasures of country or bush life in Australia. Gould says, " The white-backed species is more wary and shyer in disposition than the black-backed species." This is hardly my experience, but the note in the white- backed species is certainly louder than that of the more 150 DESTRUCTIVE INSECTS OF VICTORIA : northern form. In many birds it is the male that sings or warbles, but in the case of the Magpie both the sexes give forth their delightful note. As destroyers of chafer grubs, cutworms, and grass- hoppers, the magpies have few equals. During ploughing operations, they may be seen following hard at work at the grubs, which are devoured in enormous quantities. The nest, which is built of sticks, twigs, &c., and is lined with grass and feathers, is usually located up in a tree, a commanding position being frequently selected. The eggs are usually three or four to a clutch, but some- times five have been found. This bird should be protected as far as possible, but when it appears in such numbers as to become a pest to the farmer, a judicious thinning out may be desirable. The Magpie is found also in New South AVales and South Australia. «. ■.■ \. /- C. \'ald. Aiutciscii. De C. French, Dtiiu! YELLOW-BREASTED ROBIN. (Eopsaltria Aiistrnlis, l.atliaiit). Plate CXXXIII. ()slu)lilsl(ine (S- Co., I'rint. YELLOW-BREASTED ROBIN. 151 CHAPTER CXXXIX. Yellow-breasted Robin. {Eopsaltria Australis, Latham.) As this beautiful bird is not, strictly speaking, a true robin, it is known to ornithologists as a "" Shrike " Robin, but, as all growers know it as the Yellow-breasted Robin, I have adhered to the old name. The full-grown male is slightly smaller than the one illustrated. The female is much the same in colour, but smaller in size, and, as Gould says, has the rump olive instead of yellow. The nest, of which Mr. Campbell has- obtained such an excellent photograph, has been described by him as being cup-shaped and beautiful in form, con- structed of fine twigs, but chiefly of bark, with lengthened pieces of outer bark, sometimes 2 or 3 inches long, stuck on perpendicularly outside by means of spiders' web, and further ornamented, especially about the rim, with lichen, lined inside with rootlets and pieces of dead fiat sword-like grass, or with whole small dead leaves of eucalyptus. The nest is usually placed low in a fork or on a horizontal branch of a tree in the scrub or a creek or in a forest. This is one of the greatest favourites among birds ; its confiding manner, somewhat slow movements, and cheerful note render its presence welcome at all times. In the dense gullies in the Dandenong and other ranges, its delightful note may be heard before darkness sets in, and even in the Tea-tree {Leftosfermum) bay fringes it is by no means uncommon. The Yellow Robin has a marvellous appetite, and there are few birds of its size which destroy so many insects. It is one of the fniit-growers' best friends, and should be 152 DESTRUCTIVE INSECTS OF VICTORIA: protected. Unfortunately, the slow movements of these birds, and the ease with which their nests are found, render both birds and eggs an easy prey to the egg collector and the small boy alike. It is to be hoped, if only for the sake of the growers, that this bird will be rigorously protected, more especially in the mountainous districts. It holds the palm for general usefulness, and as a destroyer of noxious insects of all kinds. The Yellow Robin is found also in New South Wales, South Australia, and South Queensland. C. C.

Southern Stone Plover. (Burhinus grallarius, Lath?«m.) The Southern Stone Plover is a very valuable bird, commonly, though erroneously, called the " Curlew," which is, however, a totally different bird. The Curlew has a long, incurved bill, whereas the bill of the Stone Plover, as our plate shows, is quite straight, and much thicker in proportion to the size of the bird. The natural home of this bird would appear to be in fairly level dry country, but T have also met with them in dry ranges, and, as Mr. Campbell says, "" Whether in the forests of Queensland, or in the vast woods of Gipps- land, or the drier tracts of the interior provinces of Western Australia, every dweller of the bush is familiar with the weird melancholy calls of the bird at night." The Stone Plover is remarkable, if only for the prominent eves and somewhat awkward gait when seen skulking behind some tussocks, evidently trying to divert the attention of the passer-by from its nest ; a peculiarity not by any means confined to the bird under notice. The eggs, usually two, are deposited on the bare ground, and are pale-stone or light-buff, blotched all over, sometimes with markings of umber and dull-slate. According to Mr. Campbell and others, the breeding months include August to December, but I have seen them early in January. Mr. A. J. North says the bird often resorts to the same spot to breed year after year, even though its eggs are repeatedly taken. Mr. Campbell mentions having picked up near Lake Tragowel, Victoria, a pair of eggs just chipped, and by night the young birds 154 DESTRUCTIVE INSECTS OF VICTORIA : were able to stand and feed themselves. The prevailing colour of the young in down is a light-grey, with a dark marking in the shape of an oval line extending from the head to near the end of the back ; dark lines also extend from the head towards the tail. The young, if alarmed, hide themselves, and lie quite motionless with necks out- stretched, rendering their discovery a matter of difficulty. It would be difficult to speak too highly of this bird as a vermin destroyer, especially in gardens. It has many advantages over the well-known Jamieson's Gull, as it is more voracious and persistent in its search for slugs, &c., and is also more easily reconciled to captivity than even the Sea Gull itself, the latter being always on the alert to try and make its escape. A friend of mine had one of these useful birds for years, and during the whole time the garden was kept wonderfully free from pests of any kind. Although the Stone Plover is not a very common bird in most parts of Victoria, Mr. Campbell mentions having seen as many as 50 in a flock in the Cardwell district of North Queensland. It is found all over Australia and Tasmania. L. C. Vald. Andersen, Del. r. French, nircxtt. BOOBOOK OWL. (Ninox boobonk. I.atliain). Plate CXXXV. Osboldstone &■ Co., Hunt BOOBOOK OWL. 155 CHAPTER CXLI. BooBOOK Owl. {Ninox hoohook, Latham.) This handsome little owl is well known to most of us as the bird which makes the cry of " mopoke," or " morpork," although for years this fact was doubted by many excellent naturalists and others. Formerly, it was believed that the cry of " mopoke " was made by the Common Podargus, or Frogmouth, and Gould has stated as a fact that one of the latter birds kept in cap- tivity did actually make the noise alluded to. My own opinion, and that of others accustomed to the bush, is that both these birds, namely, the Frogmouth and the Boobook, can emit somewhat similar sounds. The colour of the Boobook Owl is a rusty-brown and white. Clould remarks that the sexes offer but little difference in the colouring of their plumage, but the female is the larger of the two. A great diversity is found to exist in the colouring of the irides, some being yellowish- white, others greenish-yellow, and others brown. The eggs (three to a sitting) are white and finely pitted, and Mr. Hall gives the measurements as follows :— Length, 1 • 5 inches ; breadth, 1 • 3 inches. They are deposited in holes in trees. In Mr. Campbell's book, an excellent photograph is given, showing one of our well-known naturalists climbing to a hole in which eggs are supposed to have been deposited. The Mopoke is one of our most useful insect-destroying birds, especially in the case of night-flying beetles which are so destructive to our forest trees, as they kill and devour them in the most wholesale manner. They also destroy mice and other small vermin. 156 DESTRUCTIVE INSECTS OF VICTORIA: Although this bird may be regarded as quite nocturnal in its habits, it can fly by day, and I have seen them when, accidentally or otherwise, disturbed fly oft' to a considerable distance, usually making for some dense foliage in which to hide. Mr. Keartland, well known as a bird observer, mentions having seen one of these owls in the act of devouring a small bird. The Owls will nearly all take birds, and, as is well known, the giant of the family in Australia, namely, the Powerful Owl, has the instinct of a bird of prey, and lives largely upon the common Brush- tailed Opossum, which it tears out of its hole in the trees, and soon makes a meal of it. Mr. Hall rightly says — " When we consider that there are some 765 — [There are a few over this number. — C.F.] — birds in Australia, and only, say, two dozen able to do the night work of checking the ravages of insects or other animals, we should see that a careful preservation of all be strictly enforced." The great ornithologist, Gould, writing of Australian birds, says, "In no other country is there a greater proportion of insectivorous birds than in ours, and certainly none in which nocturnal species as Podargi (Frogmouths) are more numerous. This valuable bird, which is found in Australia and Tasmania, and also, according to Mr. Campbell, on Lord Howe Island, should be carefully protected against all comers. C. C. Brittlebank, Dd. C.

The Spine-tailed Swift is a splendid bird, and in size is nearly half as large again as our illustration. The White- rumped Swift is a bird which is frequently seen in company of the one under notice, but the difference at a distance would hardly be detected by any one but a bird observer. Unfortunately for us, the Spine-tailed Swift is strictly migratory, reaching here early in November, and staymg onl}- till February. Mr. Gould and other observ^ant naturalists inform "us that they have never seen one of these birds at rest in Victoria, as they are constantly -on the wing, and in search of insects, which they devour in enormous numbers and far beyond ordinary attempts at calculation. Thev flv with great rapidity, and Gould says that it is possible for a Swift to be hawking for insects on the continent of Australia at one hour, and at the next to be similarly employed across the Bass Straits in Tasmania. As another illustration of the rapidity of the flight of this remarkable example of the feathered world, Mr. Hall, in his well-known work on insectivorous birds, states that a Swift has never been known to rest on its feet in Victoria, and only a doubtful one in Australia, and he further says the birds build in China, and can breakfast in Asia and dine in Australia on the same day. Not an insect that I know of can escape when once pursued by these birds, as they fly like a flash, and rarely miss the object of their attention. 158 DESTRUCTIVE INSECTS OF VICTORIA: It is a singular fact that, although this bird is supposed to be known so far back as Pallas, both nest and eggs are, according to Mr. Campbell, as yet undescribed. Mr. Jerdon, the late well-known ornithologist, states that the Spine-tailed Swift breeds amongst the huge wall-like crags of the Himalayas, and Mr. Campbell, in quoting Mr. Allen Owston, of Yokohama, says that it breeds under the Kegon waterfalls near Nikko, Japan, and that the rock under the falls consists of alternate hard and soft layers, making a series of shelves, and the Swifts breed in the recesses between the shelves. The outer edges of these shelves or ledges are so rotten that they w^ill not bear the weight of a man, and therefore the place is practically inaccessible. Swifts, like the Swallows, are the faithful friends of the rural public at any rate, and should be fully protected. The Spine-tailed Swift has been found in Australia and Tasmania, also South-eastern Mongolia, Eastern Siberia, China, and Japan, and, according to Mr. Campbell, reported as a straggler twice to Great Britain.

Reed Warbler. {Acrocephalus Australis, Gould.) This is a useful and a charming little bird, which has been placed by ornithologists as belonging to the family of true thrushes. The colour is that given on the plate, the bird, however, being somewhat smaller. It is migra- tory, arriving usually in the early spring. The sexes are alike in general appearance. The nests are usually built in reeds, but sometimes in Polygonum or in bulrushes, a twig of Polygonum being figured on our plate. The eggs are usually three to four, and are well known, unfortunately, to the egg-hunter. The Reed Warbler sings both by day and night. I shall always look back with pleasure to a moonlight trip which the celebrated artist, the late Miss North, and myself had to secure this bird's nest and eggs in its natural position for the British Museum. The song is very sustained and melodious, rendering the bird a general favourite. Mr. Campbell says that on the margins of the Yarra some of the Reed Warblers, on account of the absence of reeds, suspend their nests in the drooping green tresses of willows that hang over the river. As a rule, the Reed Warbler builds over water ; but Mr. Campbell remarks that instances are known where nests have been observed on dry land about 50 paces from water in herbage such as flowering stems of dockweed. This bird has somewhere been alluded to as a seed-eater, but the good which it does far more than compensates for the loss of seed it causes. Its principal food is larvae, nocturnal moths, and small beetles, also flies and other dipterous insects. 160 DESTRUCTIVE INSECTS OF VICTORIA: This lovely little bird has a claim, especially on the rural public, not only for its melodious note but lor its persistent efforts in destroying insect life. The Reed Warbler is found also in Queensland, New South Wales, Victoria, South Australia, and Tasmania, and, according to Dr. A. R. Wallace, on the Islands of Lombock, in the Malayan Archipelago. ■C.

WHITE-THROATED NIGHTJAR. 161 CHAPTER CXLIV. White-throated Nightjar. {Eurostopus albigularisy Vigors and Horsfield.) This is a splendid bird, feeding exclusively on insects. The male (see plate) is much like the female, but the latter is somewhat larger, and a trifle lighter in colour. The egg illustrated is also a little larger than the natural size, and is deposited on the bare ground without a covering of any kind. I once found a very fine specimen of this rare egg near Briagolong, in Gippsland. The egg was out in an open space in lightly-timbered forest country. I am. of the opinion that many of the eggs so deposited are destroyed by foxes, iguanas, and snakes, as the birds themselves are not rare. That celebrated ornithologist, Gould, says, " During my visit to Australia, I had frequent opportunities of observing this species. How far it may range over the Australian continent is not known. I have seen specimens in col- lections formed at Moreton Bay, Queensland, and I have killed three or four individuals of an evening on the cleared land of the Upper Hunter, which shows that it is far from being a scarce bird in New South Wales. In all proba- bility, it is only a summer visitor to the colonies, for it was at this season that I observed it. In the daytime it sleeps on the ground, or on some dry knoll or open part of the forest, and as twilight approaches sallies foi*th through the open glades and small plains or cleared land>. in search of insects. Its fliglit, which is much more powerful than that of any other species of the family that I have seen, enables it to pass through the air with great rapidity, and to mount up and dart down almost at right angles, when- ever an insect comes within range of its eye, which is so 162 DESTRUCTIVE INSECTS OF VICTORIA : large and full that its powers of vision must be very great. Most of those obtained were gorged with insects, prin- cipally beetles and locusts, some of which were entire and so la roe as to excite surprise how they could be swallowed ; in several instances they were so perfect that I preserved them as specimens for the cabinet." Mr. R. Hall remarks that, judging by the scarcity of the birds in winter time, it is probable that it goes further north to winter, and to get the advantage of a warmer latitude. The value of this bird to those engaged in forestry can hardly be over-estimated, as the great family of Longicorn beetles, flying as they do by night, fall an easy prey to this and other birds and of these beetles they must consume enormous quantities. This valuable bird should be most carefully protected. The whole family of the goat-suckers {Ca'primulgidoe), to which it belongs, are strictly insecti- vorous in their nature, and worthy of the most strict preservation and protection. The White-throated Nightjar is found in Victoria, New South Wales, South Australia, Queensland, and Papua. SPEAYIXG APPARATUS AND MATERIALS. 163 SPKAYLXG APPAHATUS AND :\[ATEErAPS. There is little to be added in regard to spraying and spray materials since the publication of Part IV. During the past season, many local brands of arsenate of lead have been placed on the market, and excellent results have been obtained, proving that this mixture can be produced locally at a much lower cost than the imported article. Many of these brands have been tested bv the Department, and the particulars of the analvses mav be found in the Journal of the Department of Agriculture for October and December, 1910. The formula recommended by the Department has been largely in use, as it is easy to prepare, and the cost is slight. THE "FRIEND POWER SPRAYER. During the last couple of years, many of the leading orchardists have discarded the old-fashioned hand spray pumps, and have purchased the up-to-date motor spray pumps, and, according to their statements, excellent results have been obtained. Some of the principal benefits to be derived from using the motor spray pump are that the spray mixture Avill go further, will be more evenly distributed, and one man can manage the outfit, whereas by the old method two or more men were required to work the hand pumps, and the mixtures were not evenlv distributed over the trees ; in addition, the wages of the two men were an extra item charged against the iipkeep expenses of the orchard. These motor spray pumps are placed on carts or patent trucks, and can be drawn over the rough ground without any trouble. 164 DESTRUCTIVE INSECTS OF VICTORIA A new bi-sulpliide of carbou injector has been placed on the market, which is a decided iuiprovenient on the older injectors, as there is abso- lutely no leakage, and thus a great saving is effected in the quantity " ATTILA " BISULPHIDE OF " BULLDOZER SPRAY CARBON PATENT INJECTOR. PUMP (NO. 2). of liquid used. The cost of treating phylloxerated vineyards with this injector is greatly lessened, and the work can be done niuch more rapidly and with greater certainty. SPRAYING APPARATUS AND MATERIALS. 165 Every season growers are learning more and more the value of spraying, and in many cases as high a percentage as 98 or 99 of clean fruit has been produced in well-sprayed orchards. Various tobacco mixtures have been tried with good results, the nicotine spray being especially usefiil in coimexion with the Thrips pest in potatoes. BAVE-U POWER SPRAYER. Benzole emulsion continues to be effectual in dealing with Thrips, and by means of the " Strawsonizer " machine, placed in an ordinary cart and worked by hand, the work can be carried out effectively. Eed oil and crude petroleimi have given excellent results against Scale insects, Red Spider, and Woolh' Aphis. Lime and sulphur has proved the best spray for Peach Aphis, the spraying, of course, being done while the trees are dormant. 166 DESTRUCTIVE INSECTS OF VICTOKIA: INDKX 'IX) i\\irr \' Acrocephalus Australis >Esiotes notabiiis Apina calljsto Arseocerus fasciculatus Arsenate of Lead— Aualj'ses of for Orange ButtoiUy for Tiger Moth for Tomato Beetle Artices glatignyi Aspidiotus Rossi Australian Bustard B.
