Ql t>is rUEFACE. The Anopheline group of mosquitoes is made up of several distinct species, some found in one part of the world and some in another. It is the group to which all those particular species of mosquito belong wl)ich are known to act as carriers of malaria. When one of these mosquitoes bites a malaria patient, it sucks in with the blood of the patient some of the parasitic organisms to wliose presenc(3 in the blood the malaria is due ; these parasites reproduce and multiply within the body of the mosquito, eventually make their way into its salivary glands, and thence can be injected into the blood of the next person bitten by the insect. Three species of Anopheles are indigenous in Britain, two of which, namely A. viamilipennis Meig. and A. bifiircatus L., are known to be malaria carriers. A. maculipcnnis is the species that is most active in the spread of malaria in Southern Europe. The object of the present map, and of the text written to accompany it, is to show what is known of the distribution of those three species of Anopheline mosquitoes in England and Wales. Such knowledge becomes of very great importance at the present time, owing to the fact that there are now a great many infected soldiers in this country who have been brought in from overseas, and who constitute a source from which malaria may be spread by the agency of the mosquitoes. Mr. W. D. Lang, to whom the preparation of the map has been entrusted, has devoted much time to the work, and has endeavoured to do his best with the means within his reach. But it is obvious that no map of the kind could be made anything like complete or final, except after a prolonged and very careful search for the species over the entire area which it covers. There are many parts shown blank on the map, where no such search has ever been undertaken, and where investigation is at the present time desirable. On the other hand, there are some large districts in which a great deal in that direction has already been accomplished, especially through the action of the medical authorities of the Local Government Board and of the War Office. For the assistance thus obtained in making the map more complete, the thanks of the Trustees are due, as well as for the assistance received from various other sources acknowledged by Mr. Lang at page 6. Here may be specially mentioned the valuable help which has been derived from the map and records pubhshed by Prof. G. H. F. Nuttall and others in the Jom-nal of Hygiene for 1901. Prof. Nuttall's map has, in fact, served to a great extent as the model upon which the present one is based. Although the map, for the reason stated, may not give an altogether true idea of the distribution of Anophelea in England and Wales, Mr. Lang has, I think, succeeded in making it give as complete and true an idea as the present state of knowledge on the subject will allow.

MAP OF ENGLAND AND WALES SHOWING THE LOCALITIES WHENCE ANOPHELES— THE MALARIA -BEARING GENUS OF MOS- QUITO—HAS BEEN OBTAINED. The accompanying map shows in what parts of England and Wales mosquitoes of the genus Anopheles have up to now been found. But it should be noted that neither with regard to range, nor to the frequency of occurrence, is the true distribution directly shown on the map. As to its range, Anopheles is Hkely to be found in suitable stations all over England and Wales ; and, as to its frequency, it is probably most abundant in the lower reaches of the larger rivers and in low-lying tracts of marshy ground. And, though the map may corroborate these two points, yet it more obviously shows the districts where Anopheles has been most keenly sought ; and this point should be borne in mind before deductions are drawn from the map as to the distribution of Anopheles. Localities where Anopheles has been obtained are indicated on the map by numbers suiTOunded with either a red ring, a blue V, a black triangle or a red rectangle. In many cases it has not been possible to determine the species of Anopheles recoi'ded from a given locality, though it is more probable than not that the species is A. maculipennis Meigen, and the numbers indicating such locahties are placed wuthin a red rectangle ; the majority of the numbers are surrounded by a red ring, and these mark the localities where ^-1. maculipennis Meigen has been obtained ; A. hifur- catns (Linnaeus) is recorded from the places whose numbers are enclosed in a blue V ; while the occasional black triangles surround numbers indicating locahties for A. plumheus Stephens. The numbers refer to the localities given in the following list. In this list the localities for A. viaculipennis are taken first, and arranged alphabetically, primarily according to the counties in which they lie, and secondarily according to the place-names themselves ; next, localities for A. bifurcatus are similarly dealt with; then those for A. plumheus; and, finally, the locahties for Anopheles of undetermined species. Besides the locality, the particulars of each record are given, and, in some cases, notes and general observations accompanying the records. The last are often of great interest, and make it possible to construct to some extent the life-history of the species concerned. For the sake of completeness Scotch and Irish records have been added in each case after those from Wales. Following the list of localities are some practical notes on how to distinguish (a) a true Gnat ( = Mosquito) from other flies ; (b) a British Anopheline mosquito (that is, a British species of Anopheles, which genus alone conveys malaria) from a Culicine mosquito (that is, a non-malarial gnat) ; and (c) the three British species of Anopheles. There is also added a brief resume of what is known of the life-history of each species. The sources whence the information given in the text is drawn are comparatively few. Some of the records have ah'eady been published, and full reference to these publications is given, except in the frequent allusions 6 A Map of England and IVales to (1) F. W. Theobald — A Monograph of the Culicidae or Mosquitoes, vol. i, 1901, and vol. v, 1910, and refen-ed to as T. 1901, and T. 1910, respectively ; (2) G. H. F. Nuttall, L. Cobbett and T. Strangeways-Pigg, Studies in Eelation to Malaria, I, Journal of Hygiene, vol. i, 1901, pp. 1-44, and referred to as N. 1901 ; (3) G. H. F. Nuttall, note on the prevalence of Anopheles, Journal of Hygiene, vol. v., 1905, pp. 485-7, and referred to as N. 1905. Other records, hitherto unpublished, have been obtained from the following sources : — (1) Col. Sir Eonald Boss, F.E.S., through Capt. F. W. O'Connor, R.A.M.C, has kindly supplied information as to the distrilmtion of Anopheles on both sides of the mouth of the Thames, from Sandwich and the neighbourhood of Eomney Marshes. Such records obtained through the War Office are acknowledged in the text by the initials W. 0. (2) The Local Government Board has kindly co-operated in the pro- duction of the map, first by asking the Medical Officers of Health in the various districts to send to the Museum any mosquitoes they may collect. In this way many records have been obtained, and particularly from south- eastern Essex, in which district, owing to the energies of Dr. J. F. Macdonald, Anopheles maculipennis has been sent from approximately a hundred localities. Eecords obtained by this means are acknowledged in the text by the initals L. G. B., placed after the record. Secondly, the Local Government Board, through their entomologist, Mr. A. J. Grove, have made available the records that he and others in their employ have obtained in the field. And I should like to take this opportunity of acknowledging the ever-ready help and courtesy of Mr. Grove and the trouble he has taken to supply the information in a readily available form. Such records have the initials A. J. G., L. G. B., placed after them. (3) Mr. F. V. Theobald, M.A., has been kind enough to supply a manuscript map on which are marked localities from which Anopheles has been recorded, together with notes giving, in many cases, particulars of the records. This information is distinguished by the initials T's. MS. (4) Mr. Hvigh Scott, M.A., had gathered many records from various sources with a view to compiling the map himself. When the task devolved on me, he handed me these records, and I am much indebted to him for his help and advice in introducing me to the work. In addition, he has since sent me some of his own observations as well as the records of the British species of Anopheles in the collection in the Cambridge University Museum. His help is acknowledged by the initials H. S. following the information he has supplied. (5) At the request of Mr. A. Vassall, M.A., of Harrow School (to whom I am thus indebted for information from this source), the Secretary of the Association of Public School Science Masters circularised the various Public Schools, asking them to send to the Museum locaHsed specimens of gnats. Eecords obtained by this means are marked with the initials P. S. (6) Particulars relating to specimens in the British Museum Collection have iDeen noted. (7) Various persons, learning through channels other than those indicated that localised specimens were needed, have sent such from time to time with particulars of their occurrence. The source of such records is given in each case, and a general acknowledgment of their help is here made.

H. Hamm, tlie result of observations and notes made during the last three years. H. S. (4) Since sending my last notes, Mr. Britten and myself have scrutinised hundreds of Culicidae for this species. So far, only two specimens have been detected, both 9 9 > one of these was in a house (and that one not in the centre of the city), and the other on a fence on the outskirts. We have also searched every Saturday afternoon from 8, ix, to 20, x (both dates inclusive) for the larvae, but only on one occasion did we find them, on 29, ix, and then only a single example, which produced a 9 on 12, x. The larva of this specimen was obtained from a small clay-hole filled with surface-water in Taylor's brickyard on Shotover Hill, Oxford. So far, we have not been able to detect this species in the city itself, although in previous years I have usually found a few examples in the Museum, and occasionally in my house, and have had a few brought to me from the vicinity of Port Meadow, taken in houses and biting by night. To sum up, A. maculipennis does not appear to be very abundant this autumn, as a very keen look-out has been kept every day for nearly two months past, with the results recorded above. It prob- ably hibernates in the perfect state. As to its being found in the centre of the city, the chances are quite remote. A much longer period of investigation, however, is needed to establish these con- clusions. From a supplementary report on Anopheles in Oxford, dated 22, x, 1917; obs. A. H. Hamm and H.

A. maculijJennis lives mostly in buildings, and bites nearlj^ all the year round, if warm enough. Apparently it prefers children to adults ; and a hard day's sweating is very attractive to the biter, or she finds one more easily thereby. They can always be found in dark pig-sties, calf-pens, stables, root-houses, dwelling-houses, church-towers, etc., near water. They are to be found a great deal in buildings because they ofi'er the best and commonest shelter ; but they occur just as readily in stone-quarries, if the shelter is good. Theu' numbers vary a great deal from year to year. I have caught Showing whence Anopheles has been obtained. 29 a few of these flies infested with a red parasite {Tromhidium). Tlie (J ^ swarm here iu lots of ten or twelve. The reason that no exact numhers are given in the accompanying records is that they usually swarm at a height of 18-20 ft., though I have taken them at 7 or 8 ft. When high, they are often in a column of mixed Chironomus and other flies, hut I do not suppose that I ever saw more than 16 $ ^ in one swarm. I have never yet attempted daybreak observations in the summer. The 9 lives through the winter, and is very pai'tial to warmth. As far as I know at px'esent, A. macnUpcnnis does move about (at any rate, some individuals do) in the earlier weeks of hibernation, and the same takes place in late Februaxy and early March. However, I should not expect them to leave one sheltered building and go a distance to another. But if numbers were to hibernate in, say, a loft above a shed, with plenty of room to get down, I should certainly expect some of the liveliest to come down from time to time.

(2) We have been very successful in locating the breeding-haunts of Anopheles bifurcatus in and around Oxford, (a) On 8, ix, we visited a small boggy piece of ground near Bayswater Mill, Headington, and the larvae and pupae were found quite plentifully in small depressions filled with surface water, and even the holes left by the hooves of cattle were found to contain numbers of larvae and pupae. During the whole time we were searching for the larvae, etc., the 9 ? of ^^is species were around us, biting most viciously (or attempting to bite) from Showing 7i'hcnce Anopheles has been obtained. 43 4 p.m. until 7 p.m. (summer time) ; large numbers of these were netted, (b) 15, ix, 1917 ; Hoglcy Bog ; larvae and pupae in some abundance in small bog-holes ; none found in the small stream running through the valley; no imagines met with, though we stayed until dark and netted a large number of Culicids. (c) 22, ix, 1918 ; Taylor's Pit, Shotover Hill ; large numbers of larvae and pupae in clay-holes scattered about the pit and filled with surface water ; a few 9 ? biting, but not so viciously as on 8, ix ; a fairly large swarm oi ^ $ observed at about 6 p.m., a number of which were netted for verification ; (d) 29, ix, 1917; Taylor's Pit; many larvae and a few pupae ; one or two imagines observed ; (e) 20, x, 1917 ; Taylor's Pit ; many larvae, but nearly all were small and could only recently have been hatched ; no pupae or imagines, (f) 22, X, 1917 ; Mesopotamia, just below University Museum ; between 1 and 2 p.m. tried a wide ditch running into the mill- stream, but could find no trace of larvae ; also tried mill-stream, among the weeds along the margin, but none were found. If we might venture to summarise the results obtained in the short time we have so far devoted to investigating Anoylieles in and around Oxford, it would appear that A. hifurcatus is the most abundant species, as it seems able to breed in any small hole in suitable localities. As we have seen no imagines during the last fortnight, but only an abundance of very small larvae, it looks as though this species hibernated in the larval state. We have still on hand a number of small larvae which we intend keeping during the winter as a test. We found the pupal stage quite short, averaging about six days in September and October; a few took about nine days before emerging. So far, this species has not been observed in houses.

A. maculipennis'\ ; there are always large numbers ; I have never had more than four biting at a time ; it bites cows and calves near woods in summer, and occasionally comes indoors to bite [cf. 490 Cambridge, 506 Alcon- bury Hill, 521 Lympne, 529 Wye, and 545 Oxford (2)] ; dog- mercury and nettles shelter it in summer, or heaps of fallen 44 ^ Map of England and Wales tree-tops, as spruce or any thick stuff like it ; I have never seen the $ hibernate ; in early spring the ^ $ swarm in the open spaces of woods, but come out in warmer, calm weather and swarm out in the fields and over ditches in lots up to twenty-five ; in July it gets badly infested with a red parasite [a mite, Tromhidiuvi]. 20, iv, 1910 ; $ $; swarming in quarry, at 7.0 p.m. 21, iv, 1907 ; $ $\ „ in sandstone quarry, at 5.30 p.m. 21, iv, 1907 ; J 2 ; „ at withy-bed, at 7.0 p.m. 23, iv, 1909 ; S 6 J »> ^^ sandstone quarry, at 5.30 p.m. 26, iv, 1910 ; S 6 > >> among quinces, at 6.45 p.m. 27, iv, 1910; 9 ? ; biting in sandstone quarry, at 6.30 p.m. 3, v, 1909 ; S S > swarming in quarry woods, at 6.15 p.m. 4, V, 1910 ; S S '> .) in quarry, at 7.0 p.m. 6, V, 1908 ; S S ' " ^^ sandstone quarry, at 6.45 p.m. 10, V, 1910 ; S S ' " ^^ withy-bed, at 6.30 p.m. 11, V, 1906 ; S S '> '» ill sandstone quarry. 11, V, 1909 ; S 6 > )> ill most of the woods. 15, V, 1910 ; S 6 > .' ^^ withy-bed, at 6.55 p.m. 18, V, 1909; 3 6;,, 24, V, 1909 ; ? 9 ; infested with larval Trombidium. 27, V, 1910 ; 3 6\ swarming in Severn Meadows, at 8.20 p.m. 28, V, 1909 ', $ $; va. sandstone quarry. 4, vi, 1909 ; $ $; swarming in rookery. 6, vi, 1910 ; 3 3\ ). in Severn Meadows, at 8.30 p.m. 11, vi, 1910; 3 $; 16, vi, 1909 ; S $; 19, vi, 1907 ; 3 $; 21, vi, 1910; $ $; in Severn Meadows. in sandstone quarry. by water-cress pit. in Severn Meadows, at 8.30 p.m. ; infested with Trombidium. 27, vi, 1909 ; $ 3) swarming in most of the w^oods. 30,vi, 1909; (J' ^t withy-bed, at 8.20 p.m. 21, vii, 1908; 3 3; 21, vii, 1910 ; 3 3 ; „ at withy-bed, at 8.35 p.m. 26, vii, 1906 ; 3 3 ', „ ^Y water-cress pit. 30, vii, 1910 ■,33; „ in Severn Meadows, at 8.30 p.m. 6, viii, 1910; 3 3; „ „ ■ » at 8.15 p.m. 22, viii, 1910; 3 3;,, „ „ at 7.15 p.m. 1, ix, 1910; 3 3; „ „ „ at 6.30 p.m. 6, ix, 1910 ; 3 3 ; „ at water-cress pit, at 6.35 p.m. ; in- fested with Trombidium. 8, ix, 1909 ; 3 3 '■ swarming at end of sandy lane, at 6.30 p.m. high up over bylet ditch, over starch-house field. 13, ix, 1909 ; 3 3 14, ix, 1909; 3 3 21, ix, 1909 ; 3 3 26, ix, 1909 ; 3 3 ; „ ^J water-cress pit. 28, ix, 1917; from MercuriaUs i)erennis, in New Eed Sandstone quarry, at 4.0 p.m. 29, ix, 1909 ; 3 3; swarming in Severn INIeadow^s and over bylet ditch. 30, ix, 1917 ; 3 3; swarming in batches of 10, 17, 30, and smaller numbers, awaiting the arrival of a 9 , in low- lying meadows by the Severn, as soon as the sun had set.

(3) From a large garden in the south of the city, within the city boundary ; first taken in 1908, and has appeared regularly in the same garden, in the first half of vi, each succeeding year ; in 1909 the first specimen, a ^ , was noticed on 1, vi ; and from then until 27, vii (when the collector left the city) specimens were taken nearly every day, the total for the period bemg ^1 $ $ and 133 9 9 > ^^^ the greatest catch for any day being 1 $ and 55 9 9 on 26, vi ; for the next five or six days they were also very abundant, after which they were fewer ; they have not appeared in such numbers in subsequent years ; all search for breeding-places failed to locate them, and the collector surmised that they might be above ground-level in the forks of neighbouring trees ; obs.
