INSECTA BRITANNIC A. D I P T E R A. VOL. II. FRANCIS WALKER, F.L.S.

The second volume of Diptera of " Insecta Britaiinica " com- prises the latter part of the Brachycera, with the Hyjjocera and the Eproboscidea. In the Brachycera two families are described, the Muscida and the (Estrida, and the former is divided into sixteen subfamihes. Upon closely examining the little-studied families contained in this volume,, the number of species has been found very much greater than was anticipated, and, as we are limited to a certain number of pages, only a portion of the species could be given. The British Diptera seem to be as numerous as those of Scandinavia, which Zetterstedt, in his ela- borate work, occupied eleven volumes in describing. The sub- families above mentioned are here briefly noticed. The Myopides aud the Sarcophagides are mostly described. In the Tackinides about half the British species of Tachina are omitted. The species of this genus are very numerous, aud require all their characters to be fully detailed, in order to identify them with certainty, and the omission of a precise notice of a single part of the structure is sufficient to cause a doubt as to the species. The greater part of the Muscides, and about half the Besides are described ; but the Anthomyides in this volume probably do not exceed one-fourth of the British species. Many species of Helomyzides, Lauxanides, IV PREFACE. Ortalides, Oscinides and PsiUdes are unnoticed ; but the Sepsides omitted are for the most part mere varieties. The Borhorides and the Hydromyzides are more complete^ and are copied from Mr. Hahday's excellent descriptions of the genera and species of those tribes. The Geomyzides and the Ph'ytomyzides are mostly passed over ; but the (Estrida, the liypocera, and the Bp-ohoscidea are rather fully detailed. Mr. Westwood has again prepared ten plates for this volume, Mr. Haliday's state of health having prevented his contributing the illustrations of the wing-veins of Diptera. Prancis Walker.

Al(e confertae, rarissime abortivse ; vena cubitalis simplex ; vena spuria apud venas brachiales nulla ; lobus axillaris rotundatus. Head large ; proboscis distinct ; eyes below bounded by the cheeks ; last joints of antennae forming a slender arista, attached to the third joint on its upper edge. Wings perfect, very rarely abortive ; cubital vein simple ; brachial veins without spurious vein ; axillary lobe rounded. Halteres of some hidden, of others uncovered. The Muscida are the most remarkable of the families oiDijitei'a, on account of their very numerous groups, species, and individuals, of their extensive variation of structure, and of their great import- ance in the economy of nature. The nomenchiture of some parts of their structure requires a short explanation. ^\^\\Qjrons extends from the hind part of the head to the base of the antennae, and occupies the space between the eyes ; its hinder part is the vertex, before which are the ocelli ; its fore part contains the, frontalia, which are dark -coloured, and more or less linear; in some cases VOL. II. B MUSCID^, they are partly or wlioUy divided by the triangular interfrontalia. The 23tiUmim is a soft membrane, which in many species, and espe- cially in the newly-hatched flies, appears between the antennae and the front, and is alternately projected and withdrawn. The fades extends from the base of the antennre to the epistoma ; its middle part contains two fovea, in which the antennse rest ; its lateral borders are the facialia, and are frequently setigerous. The mecUana are two triangular parts between the facialia and the optica, or borders of the eyes, a little above the lateral borders of the peristoma. The lateralla are beyond tliera, and on the lower sides of the peristoma. The third joint of the antennae attains its maximum of development in the leading groups of this family, and may be the organ of smell; it is perforated on its inner side in the larger TacJnnides. The fourth, fifth, and sixth joints form the arista, or bristle ; the fourth and fifth are obsolete in most genera. In the wings the flexure of the prajbrachial vein is gene- rally a characteristic of the TacMnides and of the Miiscides which have the most powerful flight. The radial vein springs from the mediastinal vein, near the humeral transverse vein. The cubital vein springs from the radial near its base, and is connected with the prsebrachial before one-third of its length by a thick slightly oblique transverse vein. The pobrachial vein springs like the pra^brachial and the anal from the intermediate axis, near which it is connected with them by two transverse veins. The distance of the discal transverse vein from the border is measured on the continuation of the pobrachial vein. The anal vein is almost obsolete soon after its junction with the pobrachial. The subanal vein springs from the intermediate axis. Some species are insectivorous, many are parasitic in the larva state, the rest feed on living or decaying animal or vegetable matter. The species will form two divisions : — Alulae distinct 1. CALYPTERiE. Alulae indistinct or none 3. Acalypter^. Alulce distincta.—Div. 1. CALYPTER^E. The Calypterce are generally also distinguished by their comparatively large size, compact bodies, dark or mctaUic bodies, and fretjucntly by the development of the fourth and tifth joints of the antennae or the basal joints of the arista.

The form of the body, of the antennae, and of the veins of the wings, in this subfamily, is very variable ; the prfebrachial vein is abbreviated in a few species, but in all the rest it forms a flexure, as in the three following subfamilies. With a few exceptions the individuals are scarce and the species numerous, but the reverse of this rule is more characteristic of the Mitscides. Their highly- developed structure and their rapid flight at once distinguish them from all the following groups. They may be divided into the fol- lowing genera : — a. Abdomen depressed. Phasia. a a. Abdomen not depressed. b. Abdomen arched, recurved beneath at the tip. c. Praibrachial vein joining the cubital before its tip. Ocyptera. c c. Prajbrachicil vein joining llie costal. Piiania. b b.

The Anthomyides are nearly allied to the Muscides, but may be distinguished by the straight praebrachial vein, and by the smaller alulae. Their size also is generally smaller, their bodies longer and less compact, and their flight less powerful. Their larvae mostly live on decaying vegetable substances.

The larvae of the Piophilce feed on animal substances, and leap very actively, as is described in the following extract : — " When the larva prepares to leap, it first erects itself upon its anus, and then bending itself into a circle by bringing its head to its tail, it pushes forth its unguiform mandibles, and fixes them in two cavi- ties in its anal tubercles ; it next contracts its body into an oblong, so that the two halves are parallel to each other; it then lets go its hold with so violent a jerk that the sound produced by its mandibles may be readily heard, and the leap takes place." 1. casei, L.

"The larva mines the leaves of the turnip and the pea; and on the sea-coast it is found as late as the end of October in those of the common scurvy-grass [CocJdearia officinalis), and in the lady's- fingers {Anthyllis Vulneraria). It mines sometimes in companies of four or five; but in a small leaf many of these desert the seat of the original colon}', and commence a separate establishment.

" None of tins, except the singularly-formed Musca mantis of De Geer, had been described before the appearance of Fallen's essay in the ' Stockholm Transactions' for the year 1813, in which the tribe first assumed a distinct character and definite limits. The author has here described nineteen genuine species, and cha- racterized most of the genera ultimately admitted. The Dolicho- pida were included in this tribe in the first sketch of his arrange- ment of Diptera, published three years before. Latreille adds to the tribe the exotic genus Bopalomera, and excludes from it the type of Fallen's genus H^dromi/za, Micsca livens of Fabricius, re- ferred to the Cordj/lura in accordance with Meigen's arrangement. R. Desvoidy has also placed with his Hi/drellidea a group of Cordj/lurce less aberrant (than C. livens) from the ordinary cha- racter; the type of his genus Nuphana being the C.fraterna of Meigen. Macquart, remanding Hijdromyza and Niipharia to their proper place among the Cordylwra, has further limited the Hi/dro- myzida, by rejecting all the species which have not the arista pectinate. These he has placed in his family PiopiMlida, in con- junction with many genera of diversified character and remote affinity. "The tribe, as described by Fallen in his 'Diptera Sueciae,' where he removes Hydromyza to the Scatomyzida, and rejects the addition of Bojmlomera, is one of the most remote from the Ca- lyptrate section, and can scarcely be confounded with any other * A little more apparent in Ochthera. t For an exception see Ephydra nasica. The imperfection of the same areolets is a character of the Oscinidce also ; but in that tribe they become incomplete after attaining their full development in the Lo.rocerida;. This appears as well from the indication of their Hmit in the thickening of the veins and the corresponding divari- cation of the radial and cubital veins, as from the analogy of the last-named tribe. X There is a slight exception in the subgenera Glenanthe and Teichomyxa. OCHTHERA. 249 group, unless it be with certain species of the Geomijzlda, which appear to offer the nearest affinity. Nevertheless from these tlie HijdromyzidcB may be distinguished either by the form of the head and mouth, the characteristic imperfection of the areolets of the wing, or the total concealment of the ovipositor. The greater number frequent the neighbourhood of waters, a destination indi- cated by the satiny lustre of the minute scales which clothe the face and sides. Ephjdra riparia, the feet of which are formed peculiarly for resting on the surface of pools, is liere regarded as the type of the group. The larvse of most Ephydra live among the semi-fluid green matter which mantles on the surface of stag- nant waters, or in the mud at the bottom. Desvoidy assumes that the other genera of the tribe, in their larva state, are nourished by the living tissue of phanerogamous plants ; but this view rests on conjecture, and a solitary fact observed regarding a species of Notij)Mla. The form and homogeneous texture of the face in- dicates but little sensibihty to smells, from whence we may pro- bably conclude that the larvae are not eminently saprophagous." — Halidai/.

" The tip of the abdomen of the female is furnished with a tube of a corneous substance, consisting of four pieces, which are re- tractile within each other. The last of these terminates in five points, three of which are longer than the otliers, and hooked; when united together they form an instrument very much like an auger or gimlet. Lays its eggs on the hides of oxen, which, as soon as they are aware of the presence of the liy, the whole terri- fied herd, with their tails in the air, or turned upon their backs, or stiiliy stretched out hi the direction of the spine, galloi) about their pastures, making the country re-echo with their lowings, and CEPHALEMYIA. 271 finding no rest till they get into the water. The only comnnnii- cation which this grub has with the atmosphere is at its anal ex- tremity, and therefore it has no respiratory organs at the anterior extremity. Each plate at the other end is separated by a curved line into two unequal portions, the smallest of which is contiguous to the convex belly, and the largest to the concave back of the animal. This last is distinguished by two hard brown kidney- shaped pieces, a little elevated, with the concave sides turned to- wards each other ; in this siiuis is a single small white spot, which appears to be a spiracle ; in the smallest portion are eight minute circular orifices arranged in a line. Bracy Clark thinks that he has discovered spiracles in this larva in the usual situation, but Kirby believes that they are analogous to the sj)iraculiform tuber- cles of (E. Oi'is."

" Infests sheep, and lays its eggs on the inner margin of the nostrils, from whence the maggots make their way into the head, feeding in the maxillary and frontal sinuses on the mucilage there produced. When full grown, they fall through the nostrils to the ground, and. become puppe. Sometimes the maggots make their way even into the brain, and occasion the death of the animal. In order to prevent the gad-fly from getting at their nostrils, the sheep shake their heads and strike the ground violently with their fore feet ; or run away, and, getting into ruts, dry dusty spots, or gravel-pits, crowd together and hold their noses close to the ground. The anal plates are surmounted by a central boss, which is a valve that closes the respiratory orifices." Generally distri- buted. (E. S. I.) 2. picta, Meg. ; Meig. Zw. iv. 172. 8 (1824); Curt.! B.

GASTKllOPIIILUS. 273 "Tliis is supposed to be one of tlie two species of gad-lly which infest fallow-deer. One of these deposits its eggs in an orifice it makes in the skin of the animal, and so produces tumours; the other lays its eggs in such a manner that its larvae, when hatclied, can make their way into the head, where they take their station in a cavity near the pharynx. There are two fleshy bags as big as a hen's egg, and of a similar shape, near the root of the tongue of the deer; these are inhabited by the larva? in considerable numbers, and between sixty and seventy bots have been taken from one of them. The larvae have been found in England in deer that had been killed for venison ; they were stationed in the throat, just at the commencement of the oesophagus.

Head prone ; the neck lying on the prosternum . "The species of this family pass their egg and larva state in the body of the mother, and when born are pupa?, or larva? just ready to assume the pupa state, as is proved by their size, which nearly equals that of the parent fly, by their slight motion when first extruded, by spiraculiforin {)oints which run down each side of them, and by their changing into perfect flies. Each female produces oidy a single egg. The proboscis consists of a pair of hairy coriaceous valves, which include a very slender rigid tube or siphuncle, the instrument of suction, which is formed by the union of two setiform pieces. Almost the whole of the wing is occupied by the apical areolets, which in some instances arc in- complete." 384 nippouosciDiE. fnoue. Discal trans- I vei'se vein ^complete. J 1 Ocelli ' distinct 1.

I I " The ' Histoi-y of British Sea-weeds ' we can most faithfully recommend for < its scientific, its pictorial, aud its popuhu- value ; tlie professed botanist will find \ it a work of the highest character, whilst those who desire merely to know the i names and history of the lovely plants which they gather on the sea-shore, will \ find in it the faithful portraiture of every one of them." — Annals and Magazine \ of Natural History . \ " The di-awiu^s are beautifully executed by the anthor himself on stone, the \ dissections carefully prepared, and the whole account of the species di'awn np in ; such a way as cannot fail to be instructive, even to those who are well acquainted \ with the subject. The greater part of our more common Algsc have never been ] illustrated in a manner agreeable to the present state of Algology." — Gardeners' \ Chronicle.

In handsome imperial folio, with thirty pktes. Price 3^. 16a. coloured. " In this work we have the first results of Dr. Hooker's botanical mission to India. The announcement is calculated to startle some of our readers when they know that it was only last January twelvemonths that the Doctor arrived in Calcutta. That he should have ascended the Himalaya, discovered a mmi- ber of plants, and that they should be published in England in an almost UNEQUALLED STYLE OF MAGNIFICENT ILLUSTRATION, In IcSS than eighteen months — is one of the marvels of our time." — Alhenaum.

" The work is one of durable importance. The most general reader wiU not find Dr. Thomson's journey tedious W^e have in this volmnc matter which will inform every man who reads it steadily, and follows the author's route with attention to the Map." — E.ram'mer. " To all those who desire to judge scientifically of what is possible in the cul- tivation of the ludo-Alpine Flora, which is now so rapidly enriching our gardens, works of this description have great interest." — Gardeners' Chronicle. " We can most cordially recommend Dr. Thomson's work to aU those who wish to obtain a clear idea of this magnificent and interesting region, to which our late conquest in the Punjuub has brought us into such close contiguity." — Guardian. " This is a valuable contribution to our knowledge of a remote and lately ex- plored tract of the earth's surface." — Advertiser.

By Berthold Seemann, Member of the Imperial Academy Nat. Curiosorum. In Two Volumes, Svo, with Tinted Lithographs and a New Map by Petermann. " With extensive knowledge in geography and its cognate sciences, Mr. ' Seemann possesses a close and vivid style, which expresses his ideas not only with clearness but animation." — Spectator. " Mr. Seemann is always a lively and agreeable companion, and has the merit of directing the attention of the general reader to applied Natural History rather than to questions interesting only to the student of pure science ; he now appears as the narrator of an important circumnavigation of the globe." — Gardeners' Chrouicle. TRAVELS IN THE INTERIOR OF BRAZIL; principally through the Northern Provinces and the Gold and Diamond Districts, during the years 1836-41. By the late George Gardner, M.D., F.L.S., Superintendent of the Royal Botanic Gardens of Ceylon. Second and cheaper Edition. With a Map of the Author's Route and View of the Organ Mountains. Price 135. cloth; 1 85. bound. " When camping out on the mountain-top or in the wilderness ; roughing it in his long journeys through the interior ; observing the very singular mode of life there presented to his notice ; describing the curious characters that fell under liis observation, the arts or substitutes for arts of the people, and the natural pro- ductions of the country— these Travels are full of attraction. The book, like the country it describes, is fuD. of new matter." — Spectator. " This volume is from the pen of an able naturalist, whose heart is in his occu- pation Some of the regions he visited have seldom been trodden by Europeans — never by Englishmen ; so that his observations derive value from the novelty of the matter to which they relate." — Athencvutn. MISCELLANEOUS. POPULAR PHYSICAL GEOLOGY. Illustrated on a new and striking plan by twenty double-tinted Lithograph Landscapes, each depicting some special geological phenomenon, drawn and coloured from nature. By J. Beete Jukes, Esq., M.A., F.R.S., Local Director of the Geological Survey of Ireland, and President of tlie Geological Society of Dublin. Royal 16rao. Price lO.s. 6f/. " ^Ir. J. Beete Jukes's ' Popular Physical Geology ' is one of the best of the popular scieutiiic manuals which have been published in a scries by JMessrs. Reeve and Co." — Guardian. " Mr. Beete Jukes is well known as a Geologist, and he has given the public a work at once popular and original. By original, we do not mean to intimate that he has propouuded in it new theories or original discoveries, but that the book is a writing out of his own experience, without abridgment or re-writing of other books. The result is admirable for perspicuity, for chann of exposi- tion, and for solid instruction. The book is illustrated with twenty tinted litho- graphs, from drawings by Mr. Jukes and Mr. Dunoyer, who is himself a Geologist, and they are of rare excellence as illustrations ; altogether it is an introduction to the study of Geology to be most emphatically recommended." — Leader. " This is one of the most remarkable works on Geology which have yet been published ; Mi". Jukes has struck out a new path for the geological student, and has done more to remove the diificulties which impeded his progress than any previous author, llai'ely, indeed, have we perused any introductoiy manual with greater pleasure; every word we have read has conveyed the impression that Mr. Jukes is an original observer, thorouglily conversant with his subject, and aware of the difficulties to be overcome. His language is graceful, simple, and free from everything like scientific pedantry." — Liverpool Courier. POPULAR MINERALOGY ; a Familiar account of IMinerals and their Uses. By Henry Sowerby.

With Twenty-four Illustrations by George Cruikshank. 12mo. Price 85. " If there still remains a real living unsatisfied Protectionist, we in aU hearti- ness and goodwill recommend to him the amusing and instructive ' Chronicles ' before us. ... To complete its attractions, every chapter of the work has been illustrated by the inimitable George Cruikshank." — Sherborne Journal. " The writer handles this subject in such a masterly manner — his style is so piquant, as weU as forcible, so scholarly, yet so racy — his wit and his wisdom are so skUfiilly blended — he has so cleverly worked out his motto, Ridentem dicere verum, by telling the truth laughingly — that the reader finds liimself in'esistibly carried along, and he and the book part not company until he has made himself master of the talc that he has to unfold." — Leicestershire Mercury. " This is a rare little volume. We don't know which to admire most, the author's humour or his wisdom. He has set himself the task of illustrating, in an agreeable manner, the evils of Custom, Prejudice, and Feudalism, as they exist among agriculturists. It wiU create much laughter among the merry, and convey many a lesson to the tiller of the soil. There are some very capital illustrations too embellishing the volume." — Era. " Cleverly written in a vein of pleasantry, the work perseveringly ujjroots the prejudice of the past, and demonstrates that scientific knowledge is an important element in succcssfid tillage." — Lincoln Mercur//. "The vignettes of ISIr. Cruikshank arc the happiest pi'oofs we have lately seen that the genius of this fine artist's earlier day is still fresh and unimpaired. The farmers should be very grateful to have such a nice little book provided for their especial use, entertainment, and profit." — Examiner. I 16 WORKS PUBLISHED BY REEVE AND CO.
