Probably there is no region free from Mosquitos, under which appellation are comprised various species of the genus Culex — the genuine Gnats of this country : even in the Arctic re- gions, Capt. James Ross and his companions were compelled to wear gauze over their faces during the summer months, to protect them in their fishing excursions from the venomous attacks of these tormenting Insects; in the collection, also, made by Capt. P. P. King in his survey of the Straits of Magellan I find specimens of a Mosquito, and others I have received from New Holland. I have long entertained an opinion that, like the Tabanidas, it is the females only that bite, and this opinion is almost confirmed by a careful dissection of the tro- phi, since I could not discover either a tongue or mandibles in the males ; it may therefore become a question, what does this sex live upon? I rather suspect on flowers, and it is re- markable that in out-houses and places where these insects abound, the sexes are not often found together ; I remember in the month of June to have seen the males of C. annulatus repeatedly, widiout observing one female, and last May I met with the males of C. nemorosus flying in a large swarm in the afternoon in Coomb-wood, in a dark shady hollow, and not one female was amongst them ; but on sitting down a few came out of the grass and lit upon my hand. I do not remember ever to have been bitten by C. pipiens in Sept. ; although I have seen great numbers of the females in my sleeping-room at that period of the year, but in July I have suffered very much from the bites of this and other species, and on the shores of the Mediterranean their piping note was the most terrific noise that could have assailed my ears at night, for to sleep it was impossible, until they were either satiated or destroyed. It may be useful to observe, that the Pnpse are frequently conveyed into the sleeping-room in the ewer, especially when it is filled from butts of rain-water ; in such cases the Gnats escape from the Pupae in the evening, and as soon as they can take wing, they are prepared with a keen appetite, having fasted during their imprisonment in the pupa, to attack the inmates of the apartment. There are near 20 species found in this country, a list of which is given in the Guide : I have only seen 2 specimens of the species figured ; both of them were taken at Cobham in Surrey.

The large Tipulas are known in this country by the name of " Okl Father," or "Daddy Long-legs;" and the almost vo- luntary manner hi which the legs fall off on the least touch. is most remarkable, and renders them very difficult to pre- serve. Their larvag live under ground, principally in pasture and meadow lands, where they undergo their metamorphoses ; and at particular seasons the empty pupae may be found in thousands, hall" obtruding perpendicularly from the ground. I shall describe 2 new species, give the names of some that have never been recorded as British, and as many references and habitats as space will allow. A.

Dolichopeza sylvicola is one of those valuable insects wliicli iiom its partaking of tlie characters of neighbouring genera has been called conterminous : it exhibits to us affinities ex- isting in nature by which we are enabled to approach nearer to a natural arrangement. It differs from Tipula in having only 12 joints in the antennae, and a few scattered bristles upon them, instead of 1 3 joints ornamented with whorls of hairs ; from Limnobia it differs in the length of the terminal joint of the palpus, and the long cylindric joints of the an- tennae; but the most decided and remarkable characters which at once distinguish it from both these genera are the absence of the 3rd discoidal cell, which in them is never wanting, various as the wings of these genera are, and the extraordinary length of the basal joints of the tarsi, which are all very much longer than the tibia? : — to this circumstance the generic name that I have adopted refers. In my ramble through the New Forest the beginning of last June, in a part that lies rather low and was at that time swampy from springs that appeared to rise there, upon the mossy trunk of one of the magnificent beech-trees that orna- ment the neighbourhood of Lyndhurst I saw many of both sexes of this elegant insect ; they rested as represented in the plate with their wings spread, and although it was a fine calm morning, their hinder legs, which did not touch the tree, waved backward and forward, as if the least touch would disjoint them : the trunk was so much overshadowl^d that had it not been for the white feet of the insects, which rendered them conspicuous, they would have escaped my observation; and it is a little singular that although this was on my first arrival, and I stayed some time in that neighbourhood, I never saw any more of them. Upon looking over Mr. Stephens's cabinet I found one female which he had always considered as being different to other described genera, neither does it appear, as a species, to have been before noticed. Polygala vulgaris (Milkwort), which was in flower at the time netu' the spot, is figured with the insect. oTcy^ ^ ^ 7$ %/:-^y'^-€,..yiA-^ 9^'U:/./6'S6 589. PERONECERA FUSCIPENNIS. Order Diptera. Fam.

In the Cabinets of Mr. Dale and the Author. Meigen having united Nematocera and Anisomera in his Supplement, it is probable he would also include our species with them, but as he, as well as Macquart, characterizes his group as having 6-jointed antennae, it would not be advisable to form one genus of the whole ; and unless there be indivi- duals with modified antennai, connecting the long- with the short-horned species of Anisomera, one would judge from Meigen's figures that the species ought at least to be formed into sections ; but as I do not possess any of the typical spe- cies, I am unable to throw any light upon the subject. My genus Peronecera, in allusion to the button-headed an- tennae, comprises 1. fuscipennis Curt. Brit. Ent. pi. 589. S . Which I discovered in abundance upon grass in a meadow by the side of the river near Ambleside, the 21st of June, where numbers of them were paired ; about the same time Mr. Dale took a pair near Low Wood, on the banks of Wi- nandermere. 2. lucidipennis Curt. Guide. Female piceous: antennae cinereous-brown at the base, 3 ter- minal joints of equal length, and a little elongated ; head and thorax cinereous, 2 pale brown spots behind the eyes : thorax with a broad piceous shining stripe down the middle, faintly divided, and 2 ovate spots on each side ; wings rather milky- white, nervures ochreous-brown, apical furcate nervure elongated ; halteres pale ochreous ; legs fuscous-ochre, thighs and tibiae darkest at the tips, the former pale och- reous at the base: expanse 12 lines. The only specimen I have seen I took in Perthshire in July. I may add that Mi*. H. Walker has found Nematocera nigra at New Lanark, and Capt. Blomer took a pair probably of the same species at Kenfig Pool, Glamorganshire, in June, which is now in Mr. Dale's Cabinet. I should not here notice Meigen's having given M. Win- them credit for my genus DolicJiopeza, had not Macquart seemed to be equally ignorant of its true source: it therefore be- comes necessary to state that the genus was established in this work in March 1825, as will be seen by reference to the date on plate 62, where DolicJiopeza sylvicola is figured ; and it will not be irrelevant to add that upwards of 70 dipteroiis Genera have been already illustrated in this publication.

In the Cabinet of Mr. Haliday. This genus, like many others of the Tipulidae, is very much confined to northern latitudes. Macquart has described only two species, the D. astivalis and D. apriliiia, and says they inhabit marshy woods in the North ot" France, but are both rare. The name Dixa is descriptive of the two bifurcate nervures of the wings, which distinguish it from its congeners. I am indebted to A. H. Haliday and F. Walker, Esquires, for many of the following localities, as well as for several of the species. 1. D. cinctus Curt. Guide, No. 1.

Smaller than the insect figured ; and as all the spe- cimens I have seen were alike, I think it is distinct from D. nehdosa : the 2 central black lines on the thorax are much longer, and the clouds on the wings much less distinct than in that species. I have taken this insect the middle of November, in the flowers of the Ivy at Arno's Grove, where Mr. Walker also finds it, as well as in the Isle of Wight, the middle of October. 6.

This remarkable insect is distinguished from all others by its long pubescent or rather pilose antennae : it seems to be inter- mediate between Bolitophila and Macrocera, having the neu- ration of the wings of the one, and the elongated antennae of the other ; but these contain 1 6 joints, which is a greater num- ber than they are composed of in those genera : the situation also of the ocelli is different to those of Macrocera, and their equal size do not accord with the Bolitophilae. The only example I have seen of this pretty insect was taken by W. W. Saunders, Esq., whose name it bears, and to whose liberality I am indebted for the specimen, accom- panied by the following observations. " The Gnat I caught on the 9th of April last, while it was resting on a wall in an outhouse at Weston Turville, near Aylesbury. I remarked that the hind legs of the insect were stretched out behind, without touching the wall, in the way that Gnats are often seen to hold them, and that the antennas were gently curved forward, forming perhaps an angle of forty-five degrees between them." The Plant is a variety of Thymus Serpyllum (Mother of Thyme). I drjy 637. MACROCERA STIGMA. Order Diptera. Fam. Tipulid.'E. Type of the Genus, Macrocera lutea Panz.

I SHOULD not have relinquished Latreille's generic name Asindulum had he not by some accident described (in his Histoire Naturelle, 1. 14, p. 290, and in his Genera Crustaceo- rujn, Sj-c. t. 4, p. 261) and figured (in the latter work, tab. 15, f. 1.) an insect for the type which appears to be more allied to the Empid(E, having an elongated proboscis inflected under the breast, "Proboscis elongata, sub pectore inflexa," &c. which would exclude it from the Tipulida, none having a long proboscis excepting Culex and Anopheles, and in them it is porrected. Platyura is distinguished at once from the neighbouring genera by the transverse nervure at the apex of the wings, and many of them by their depressed abdomens. With their habits and economy we are unacquainted : it is supposed they live upon fungi. The following species are in Mr. Stephens's cabinet. 1 P. atrata Fab. 2 lineata Fab. a laticornis Meig. pi. 8./. 1 9—2 1 . 4 rufipes Hgg. 5 semirufa Meig. 6 nemoralis Meig. 7 flavipes Meig. 8 cingulata Steph.

Our species, a female of which is represented, is not uncommon in the neighbourhood of London; I have met with it in Coombe Wood and upon paling near Kilburn, in the early part of June of the present year. Some of the species are much larger, and far more rare. Poa rigida (Hard Meadow-grass) accompanies the insect. d// -V ^a/'.i/^ K^'.- (?^ lJ> U/,W/c, 641. SCIOPHILA SYLVATICA. Order Diptera. Fam.

The appearance of the fungivorous Gnats being influenced by the moisture of the atmosphere, which is so essential to the generation of the vegetables on which the larvae feed, we meet with them in woods and even at our windows at late and early periods, and in wet seasons and in humid situations du- ring the greater })art of the year. The Sciophilae are admi- rably characterized by the minute aehrolet in the wings.

The nervures in the wings of our insect agreed so well with those of one of Meigen's divisions of Mycetophila (tab.9.f. 18.)> that I included it in that Genus in my Guide. On a more care- ful investigation, however, I find that the ocelli are distinct, and not remote, as in Mycetophila, neither are the posterior tibiae spined externally. Leptomorphus seems to make a near approach to Gnoriste, of which having no specimens I cannot speak with confidence ; but it is at once distinguished from that Genus by its short Trophi : and the lengthened terminal joint of the palpi, and the situation and relative proportions of the ocelli, seem to connect it with Platyura. I suspect, therefore, that its natural situation will be between those two Genera. Most, if not all of the insects forming this part of the family of Tipulidse live in Fungi in the larva state : and the following table of Genera may be of service to the student in separating them. Antennae nearly as long, or longer than the body. 2nd subcostal nervure terminated abruptly Bolitophila. continued to the apex Macrocera. Antennnae much shorter than the body. Terminal joint of Palpi elongated. 3rd lateral nervure forming a cell in the centre. . Synapha. Antennae with cup-shaped joints. Nervures simple Mycetobia.

In the Cabinets of Mr. Stephens and Captain Blomer, The terrors created amongst cattle by the Tabani (called by the Greeks (Estrus, by the Romans Asilus) have been recorded by the ancient poets; modern naturalists have unfortunately applied these terms to insects of very different habits, our CEstri appearing to have been totally unknown to them. In this country they are called the Breeze. Their flight is easily detected by the vibration of their wings, which greatly terrifies and agitates cattle, especially horses and horned cattle, the hides of which they are able to pierce, making a w^ound that must be very painful, when we consider the compound apparatus with which it is made. The dissections of these parts are more elaborate than usual, no less for the information of those who may feel interested in the history and curious struc- ture of this well known genus, than for the instruction they afford to the student from the completeness of every part. The lip (g), composed of 2 muscular hollow lobes, enables the insect, I imagine, to attach itself firmly to any object it is desirous of attacking : the parts marked b, c, d, and probably e, are forced into the object in a compact body, the mandi- bles assisting principally in this operation, being most exqui- site lancets, one of which is figured separately at E, if the maxillae (e) be admitted into the wound, from their elasticity, it is probable, for the purpose of dilating it. The palpi (f) are useful in dividing the hair of the animal, and assist in deter- mining the blood to the spot ; and the lip and tongue (b and c, highly magnified at F, at which point is the pharynx) are grooved, and when united form a tube for the blood to pass through : the former appears to have a gland at the apex, which may assist in drawing it up. There are 11 or 12 species of this genus in Britain, and we may expect to discover many more, as Meigen has de- scribed 42. We have, 1. T. bovinus L. ; 2. autumnalis L. ; 3. signatiis Meig. ? 4. micans F. ; 5. tropicus L. ; 6. solstitialis Meig. ; 7. luridus Fallen ; 8. montanus Meig. ; 9. pagarius F. ; 10. r2istic2is L. ; 11. alpinus Schr. The last species being new to Britain has been selected for the drawing. Two females were taken last autumn by Captain Blomer near Bideford, North Devon. Schrank having first given it the name of alpinus, Meigen's name has been here dropped. The Tabani are all to be found from June to September in places inhabited by cattle, viz. marshes, meadows, heaths and forests, frequently settling upon gates and paling, the males upon flowers : those of T. nisticus I have found in gardens. The plant is Matricaria Chamomilla (Chamomile Fever- few). -Odr 705. RHAGIO HEYSHAMI. Order Diptera. Fam. Rhagionidae or Leptidae. Type of the Genus, Musca tringaria Linn.

In the Author's Cabinet. Meigen has included in Leptis insects which I have long considered as forming two genera, and I find that Macquart holds the same opinion. Meigen has taken an objection to the name of Rhagio because it is similar to Rhagium, a genus of beetles, which I conceive is not a sufficient reason for drop- ping the original name g^ven to the group by Fabricius, adopted by Latreille and Olivier, and by which they are ge- nerally known. Rhagio is easily distinguished from Leptis (fol. 713) by its smooth body and drooping attenuated palpi ; the wings and antennae offer but trifling differences. These flies like many other diptera delight in resting on the trunks of trees, generally standing high on their legs, with their wings half expanded and their heads downward. De Geer says the larvae live in the earth, and that of R. vermileo is very remarkable : we learn from him and M. De Romand that this larva forms small pits in the sand like the ant-lion, at the bottom of which it lies, and devours ants and other prey which fall to the bottom. M. De Romand has ascer- tained that the larva can exist upwards of six months without food, and M. Macquart states that they live at least three years (months?) before they change to pupae ! 1. strigosus Meig. vol. 2. />. 88. 2. scolopaceus Linn.

The extraordinary disparity of the sexes led Fabricius into the error of designating them as two species, and Latreille has given them a third name. This beautiful but sluggish species is evidently attached to the banks of rivers, where it sometimes occurs in great abundance, and after floods large masses of the males have been found sticking to culms of grass, on the banks of the Severn at Bridgenorth the end of F May ; and Mr. Bird gave me a conglomerated body of the females, so closely packed as completely to conceal the catkins or fruit of f the Alder to which they adhered. I have taken the female near Slaughter in Gloucestershire in June ; Mr. A. Cooper found it the same month upon willows near the head of the river Darent : it has also occurred in Derbyshire. 2. marginata Fab. — Atherix Doii, Brit.

Belzebul from Anthrax, nd given it the generic name of Stygia (since superseded by Lo~ \atia), the family now contains four genera, two of which are Bri- sh. It is probable that the sombre aspect of some of the exotic pecies may have induced authors to apply the name of Anthrax to lis genus ; and the association being carried further, has led to the eccentric use of such names as Abaddon^ Belzebub, Cerberus, Hot- tentotta, Lar, Lucifer, Tantalus, &c. for some foreign species. The Anthraces fly in the sunshine, they delight in dry sandy districts, and subsist upon the juices of flowers, which accounts pro- bably for their wanting mandibles. The origin as well as the form of the parts composing the mouth, not being so accurately exhi- bited as could be wished by Meigen and other authors, I have en- deavoured, as far as possible, to investigate the subject for the in- formation of the student. Meigen has described 58 European species ; but as they delight in a warm climate, we cannot ever hope to increase our genus much beyond its present number, and even those that have been met with in Britain are far from common. * Submarginal nervure united at its origin, to the transverse one of the discoidal cell. 1.

On fine bright mornings in the early part of spring, the ento- mologist is delighted at seeing the two larger varieties of these beautiful flies hovering over sunny banks covered with prim- roses and violets, from which they extract the honey contained in the nectaries, whilst on the wing : they also frequent woods and plantations, where the sun has access, before the trees are clothed with their summer verdure. As the species are not numerous I shall give the characters of those which have been recorded as British. I appear to have two that are undescribed, one of which I supposed was the B. 7iitidulus Fab., but I am now convinced it is not, and Nos. 3, 4, and 8 are admitted on the authority of the Syste- matic Catalogue. 1. major Linn. — Curt.

In the Author s and other Cabinets. Phthiria is one of the Bombylidae, from the type of which family it is distinguished by the neuration of the wings, the narrowness of the abdomen, and the shortness of the basal joint of the antennae. They seem also to differ in their habits, for I have never seen the Phthirise hovering over flowers like the large and beautiful Bombylii. It is probably 20 years since I took two females of P. puli- caria on the coast of Suffolk, one of which I presented to my friend Dr. Leach, who placed it in the British Museum. Be- fore that time it was unknown in this countr^f ; and it is re- markable that it should not have been detected since, until I visited Suffolk last June, when I found a sufficient number to supply all my friends, and had the good fortune to detect the male, which 1 had never before seen. The sexes are so very dissimilar, that unless they were taken together, any one would consider them as different insects. P. ]mlicaria was recorded in my Guide under a new name, for Mikan, who describes only the female in his "Monogra- phia Bombyliorum Bohemias," takes no notice of the yellow line bordering the sides of the thorax, which is very conspi- cuous, especially in rubbed specimens; neither does Meigen, in his essential character. I found both sexes of the Phthiria sucking the florets of Hieracmm pilosellce and Hypochceris radicata (pi. 385.) on the Denes at Covehithe, Suffolk, and I observed a few also, probably sheltering themselves from the wind, in the flowers of the Yellow Horn Poppy (pi. 66.) and the plant figured. In the neighbourhood of Montpellier I saw 2 or 3 in the flowers of a Thistle, but could not capture one. It seems to be rare upon the continent, for when I sent to Germany for specimens to dissect, I only obtained a female; and Mikan says, he once took it the beginning of summer in the flowers o^ Chrysanthe- mum Leucajithemiim (pi. 162), in the vicinity of Prague. The handsome Plant represented, with a specimen of the male insect, is Convolvulus Soldanella (Sea Bindweed). /J-^ '"^'^'^'^ ''a'UU^n.^SQ-: //Si/ 153. DASYPOGON BREVIROSTRIS. Order Diptera. Fam.

Dasypogon is a handsome genus embracing 44 described European species ; it is closely allied to Asilus, and probably connects that genus with Laphria : it is easily distinguished from either by the nervures of the wings, those of Asilus having 2 discoidal cells, and Laphria having a pedicel to the sub- marginal cell, the structure of the antennae is also very dif- ferent to those of the latter genus. Hitherto there has been but one species recorded as British, we therefore consider ourselves fortunate in addino- this second o to our catalogue, and in Mr. Walker's cabinet at Arno's Grove we lately saw another with clouded wings. 1.

Specimens of this fine insect have been taken I believe near Bristol, in sandy situations in June and Jul^^, and are in the cabinets of the British Museum and Mr. Stephens. 2. D. brevirostris. The male of this insect, which is remarkable for the length of its posterior feet as exhibited in the figui'es annexed, I first took at Darent Wood, Kent, the end of June : about the same period Mr. Dale and the Rev. L. Jenyns met with it in plenty on Newmarket Heath, in a place commonly called the Devil's Dyke, and the middle of August I found several pair settling upon the plants that grow in profusion in the North-Foreland meadow, Dover. Its habits are very similar to those of Asilus, and a female that I saw resting upon paling early in the morn- ing exceedingly resembled the smaller species of that genus : at a more advanced period of the day, they became like their congeners very wild and active. They are evidently attached to chalky districts, where the plant figured, Chlora perfoliata (Perforated Yellow- wort), is also abundant. ■^i/-./y d^:€«il&,^„^„ 7/.v: '/: /rfK c^ - f % o^o 94.

It is singular we should possess only I species of this fine genus, of which there are 32 described by Meigen in his work upon European Diptera ; there are indeed two specimens in the cabinet of the British Museum which may be distinct from Laphria nigra, as they are somewhat different, but it is very doubtful. It has been before observed that the family AsilidcB em- braces the genus Asilus of Linnaeus, with which Laphria gilva (the type) was associated : it will however be evident on com- parison with plate 46 that their structure is very different : we need here only notice the form of the antennae and lip, and the articulate palpi. Laphria nigra appears to be partial to nut-trees, upon the leaves of which I took a male in a very hot day in the month of June 1821, in DarentWood, Kent, since which 1 have not met with it. In the neighbourhood of London it occasionally appears, and has been captured by Mr. Stephens at Darent, and at Coombe Wood by Mr. Westwood the middle of June : it is, however, by no means a common insect, and has never before been figured. Sison Amomum (Bastard Stone Parsley) is figured in the plate. 46 C%i^/^J-CuAit<' jUlri 'iU / JSti 46. ASILUS GERMANICUS. Order Diptera. Pam. Asilidse Lat., Leach.

The vast stores of ISTatural History, especially insects that have been received from all parts of the globe since the days of tlie immortal Linnseus, have increased our subjects to so great an extent, that the Genera of that illustrious man now form (as in the present instance) natural families composed of groups which modern authors have found it necessary and convenient to con- stitute into Genera, thereby rendering the investigation, so far as relates to species, much more easy and intelligible. Meigen describes 56 European Asilij about 11 of them are British, amongst which are, A. crabroniformis L. ; Jhrcipatus L. ; cestivus Schr. ; opaciis Glirth. ; germanicus L. ; albipes Meig. ; &c. The Asilus of the Eomans (Mr. W. S. MacLeay observes in the Linnean Transactions) was the (Estrus of the Greeks and the Hcematopota of the present system, a fly exceedingly annoying to horses, whereas our Asili prey upon other insects, especially the Diptera ; they prefer resting upon the ground, particularly in sandy situations; and the larvse feed upon the roots of plants under ground, where they change to pupse covered with spines. One of the most beautiful of our species is A. crabroniformis, (figured by Donovan, v. 5. pi. 180.) which is not uncommon about heaths and commons from June to September : the rarest species at present known is A. germanicus (a male of which is figured) : two specimens are preserved in the British Museum, sent from Bristol by Mr. Millard. It has also been observed in Devonshire. The plant given in the plate is Fumaria claviculata (Climbing Fumitory) . ^ 3? 661. HYBOS PILIPES. Order Diptera. Fam. Hybotidse.

As the genus Hybos and its allies seem to be related to the Tachydromidae, Empidae, and Asilidfe, I have thought it better to adopt Meigen's view of the subject and consider them as a distinct family. Meigen says the two basal joints of the an- tennae are united ; I could not discover a suture ; if there be one, the antennae ought to be described as 5-jointed.

Having no doubt that Harris's Empis clavipes is intended for our insect we should have adopted his name, had not Fabriciiis described an Empis davipes with which we are unacquainted, and therefore cannot ascertam whether it be a true Empis or an Hilara. As no figure has hitherto appeared of the female, we have preferred giving that sex, with a fore leo- of the male. Although it has not been uncommon in the neighbourhood of London the last two years, we know of no cabinet in which it was to be found, until we gave it to our friends Mr. Dale and Mr. Stephens.

I was much amused at the end of the same month by another species (probably H. globulipes) which was flying in multitudes over a pond at Hampstead, close to the surface : upon a closer view I saw the males frequently alight upon drowned gnats (Culices), holding with their dilated fore feet and whirling about the water with them ; probably extracting nutrition from them at the time.

In the Author's and other Cabinets. MoNS. J. Macquart has added several new genera to the Tachydromidae, and he has restricted the typical genus, which now contains only 6 British species. The principal distinction of this group is the incrassated anterior thighs, which in the remainder, named by him Platypalpus, are more slender than the middle pair : I find that they are serrated beneath in the Tachydromiae, and the tibiae spined on the inside, which he has overlooked: the intermediate tibiae are simple: the trans- verse nervures also in Tachydromia are straight, whereas they are oblique in the other group; the palpi and antennae are likewise different; but the latter vary very much also in Pla- typalpus. These insects, like the Empidae, seize and live upon other Diptera, for I have myself several times detected them feeding upon small flies. The Tachydromiae run with great swiftness, with their wings lying on their backs; and being prettily marked, they have the appearance of some of the small Cimicidae (Gen. 1100. Phytoceris, &c.). I shall translate the specific characters from Meigen. 1. T. arrogans Linn. — Curt. Brit. Ent. pi. ^T?. 9- — cimi- coides Fab. Found near London ; b.

In the Cabinets of Mr. Haliday and the Author. Through the zeal and kindness of my friend Mr. Haliday I am enabled to figure a new species of Drapetis, which he has discovered since the publication of my Guide. D. aterrima Hal. — Curt. Brit. Ent. pi. 397. Mr. Haliday says, " It is distinguished from D. exilis by the abdomen being entirely deep glossy black in the living in- sects of both sexes" : he adds, " The sea-coast seems the pe- culiar habitat of mine; I seldom have seen it a hundred yards from high-water mark. It was taken at Holy wood." Neither of Meigen's species have yet been discovered in our islands, but as it is very probable they soon may be, I shall give his descriptions. 1. Dr. exilis Mfg. — Meig. v. 3. p. 91. tab. 23. Jg. 25—28. " Head black, nearly orbicular. Eyes a little separated in both sexes. Hypostoma very narrow. Three ocelli on the vertex. Antennae black, approximate at the base, then bent upwards towards the side, shorter than the head with a long naked terminal bristle (25). Proboscis somewhat prominent with incumbent palpi, whose figure is not easily determined from their minuteness. Thorax shining black above, without any transverse suture. Abdomen in male entirely shining black, rather long nearly cylindric, of seven segments : in female more oval, acuminate, reddish yellow above, with black bands at the hind margin of the segments, entirely reddish yellow beneath. Thighs a little incrassated, black; tibiae brown unarmed, feet yellow. Poisers black ; wings hyaline, incumbent and parallel in repose, with microscopic hairs, rounded in front. The genus is easily distinguished by the neuration. After death the abdomen of the female becomes nearly all black from contraction, only a little of the yellow remaining visible. These flies run with extraordinary agility, so that they are hard to catch. In Aug. and Sept. common on palings. Megerle sent the same out of Austria. Male ^, female | line long." Meigen in a subsequent volume gives the following specific description of D. exilis. " Black shining ; tibiae and tarsi yellow; segments of abdomen equal", v. 6. p. 344. 2. Dr. nigra Meig. Siipp. v. 6. p. S^i. " Black, shining ; an- terior tibiae and tarsi entirely yellow, fourth segment of the abdomen the largest." " The fourth segment of the abdomen embraces more than half of its entire length. In my specimen the poisers are not visible. One male from Winthem. Fully half a line long." Mr. Haliday says, " From the correction of the characters of Dr. exilis, Meigen seems to have found the yellow colour of the abdomen a delusive character, perhaps the effect of disease. I should add that, according to my observations, all the insects of this family have three-jointed antennse. The difference therefore between this and the preceding family is, that in the Empidae the 2nd joint is the smallest, and the palpi reflected ; in Tachydromiae the ] st joint is the shortest, the palpi incumbent." The Plant is Galium palustre? (White Water Bed-straw). //9 3 ~n^^ no. HENOPS MARGINATUS. Order Diptera. Fam. Acroceridae Leach. Inflata Lat. Type of the Genus Musca gibbosa Linn.

Specimens are sometimes much less than the size repre- sented by the crossed lines in the plate. In the Author's and other Cabinets. Within the large cavity of the mouth may be seen a mem- branous flat substance surrounded by an interrupted coriaceous circle, with an appendage arising near the middle : this may probably answer to the lip in other Diptera, but without living specimens it appears to be impossible to arrive at the truth ; and the want of such an opportunity has prevented me from investii^ating the trophi of this genus so well as I could wish, which I the more regret, because Fabricius, who has given an account of those organs, appears not to have been satisfied ; and I confess that in my specimen, which appeared to be quite perfect, I was not able to detect the parts that he has described. Meigen, for reasons similar to my own, has not given figures of the mouth. The different opinions respecting its affinities render a knowledge of the trophi very desirable, and ab- solutely necessary to decide this point. Latreille and Leach placed the family to which Henops belongs between the Bom- bylidce and Syrphidce ; Meigen, between his TachydromicB and Stratiomydie. I feel persuaded that Latreille's locality is the more natural, for even Meigen includes the genus Cyrtus with his Injiatce ; and the structure of the proboscis of that genus, no less than the nervures of the wings, render it im- possible, we conceive, to remove it from the Bombylid/c ; whilst the structure of the antennae and the inflated abdomen show that there is nothing but the wings in Hetioi^s analogous to the habit of the Stratiomyda. Our genus is distinguished from Ac7'0cera, to which it is closely allied, by its subclavate antennae, which are inserted below the union of the eyes, by its almost nerveless wings and large squamulae. The only 2 species in British cabinets are, 1. Henops gibbosus Lmn. — Meig. Syst. Besch. tab. 24.y^ 1 5. — Taken in May and June on Wimbledon Common, and in Coombe Wood. 2. Henops marginatus Meig., which has several times oc- curred in the New Forest. My specimens I purchased of Mr. Joseph Standish, who beat them out of old white thorn bushes that were covered with lichen, the end of June and beginning of July. They were so sluggish in the net that they laid with their wings closed, which made it difficult to detect them; and the least pressure destroyed the rotundity of their bodies, which are very thin, and with the large wings and scales appear to be well adapted to enable the insect to float like a bal- loon in the air, subject to the influence of any current that may prevail. The plant is Chtysosplenium oppositifoliu7n (Opposite-leaved Sengreen). J'l f ^ b /o/ q9U:1^ c/t^^ .=.^cw Oct -/ 18U v^ 42. PACHYGASTER LEACHII. Order Diptera. Fam. Stratiomydae Lat., Leach.

Pachygaster ater is the only insect of this Genus hitherto de- scribed ; it is figured by Panzer, is somewhat larger than our insect, and is at once distinguished by its wings, which are brown nearlv half way from the base. P. Leachii appears to be very rare, the only specimens discovered, being a male in the Cabinet of the British Museum, taken it is beheved by Dr. Leach in Devonshire, a female (the one figured) taken by myself in the autumn, I think in the same county ; which is rendered the more probable, because, if it had been a species inhabiting the neigh- bourhood of London, it must have been met with before ; for there can be little doubt that insects so very similar in form have nearly the same habitats. P. ater is by no means a rare insect ; it may be found during the month of July in hedges and trees at Darent, Birch, and Coombe Woods. Meigen in 1804 first published this Genus under the name of Fachygaster in his celebrated work in 4to, KlassiJiJmzmb ttnd Besch'eihbng , &c., t. 1. p. 146: in the following year Fabricius^s Systema Antliatorum was published, where the Genus is called Vap2w, which Latreille has adopted ; but as it is clear that Meigen has a claim to priority, I have retained his name in preference, which I am the more inclined to do, because in liis last invaluable work the Genus is again presented to us under the name of Pachygaster. It is a little unfortunate that Germar has applied that name to a Genus of the Curculionidie ; but as that was only pubhshed in 1817, it must of course be discarded. The plant figured is Fiola odorata var. alba (Sweet Yiolet). «^>><^.- ^ CJ:^;u/tJLj mfl C^i. 305. SARGUS REAUMURI. Order Diptera. Fam. Stratiomydae Lat. Type of the Genus, Musca polita Linn.

The flies contained in this pretty genus are distinguished from their congeners by the elegance of iheir form, as well as by the brilliancy of their colours. The areolet in the centre of the wing is much smaller than in Pachygaster (pi. 42 ), which has also a subglobose abdomen ; and the antennae of our in- sects are very different to those of Nemotelus, to which it is closely related. The following are British species of Sargus : and it is re- markable that Panzer has not illustrated one of them ; and many of the figures referred to below are so bad that it is not easy to determine to which insects they belong. Most of these flies are common ; they are fond of the sunshine, and are seen resting upon the leaves of plants on the borders of woods, in hedges and gardens. 1. S. cuprarius Linn. F.

In the Author's Cabinet. PsARUs and Eumerus are related to Paragus, but the former has a protuberance in front of the head from which the an- tennae arise, and the latter has serrated posterior thighs and very short antennae, and our pretty little group is readily di- stinguished by the shape of the abdomen, the 2nd and 3rd segments appearing as if a thread had been drawn tight round them at their attachment. The following have been recorded as British species. 1. bicolor Fab."^ — Coquehert Icon. tab. '2.6. f. 9. " Abdomen rufous ; base and apex greenish-black ; tip of scutellum white : 3 lines long."

In the Author's and other Cabinets. This little genus is readily distinguished from all other Syr- phidge by the long narrow clavate abdomen. Meigen gives a figure of the head of a male with the eyes contiguous, but I have never seen that sex, which is remarkable, and it proves the rarity of the males, whilst the females are by no means uncommon. Whether all the species described by Meigen be distinct I am unable to determine ; the essential differences are slight, and there seems to be intermediate varieties; even the speci- men figured does not agree very well with that part of his de- scription relating to the dusky transverse nervures ; yet it can- not be the B. sadellata, which I first took it for, because Meigen only mentions yellow abdominal bands on the 4th and 5th segments. The following are recorded as British, but I possess only 3 of them. 1. elongata Fab.— Curt. Brit. En-f. pi. 7S7 ? ?

Male shining greenish-black, punctured, face metallic green, with scattered white hairs : antennae testaceous : eyes casta- neous-brown : thorax with 2 narrow grey stripes down the back : abdomen bright ochreous, with 3 white lunules on each side of the three first segments, all of which are brownish at the base, 3rd and 4th slightly eneous : nervures piceous : legs brownish, anterior the darkest, base of tibiae and of 4 anterior tarsi ochreous, hinder tibiee with whitish pubescence. In the Cabinets of Mr. Dale and Mr. Rudd. This pretty genus of Syrphidse is distinguished by spiny hinder thighs, by the scutel, which has a thin and sharp edge, somewhat denticulated, and the apical transverse nervure is lobed and sinuated very differently to congenerous groups. Meigen has divided Eumerus into two sections, depending on the pubescence of the eyes ; but as there are some species slightly pubescent, and age probably making a considerable difference in this respect in others, 1 fear it is not much to be relied upon ; it is a point, however, which I cannot decide, having very few species : four of the following are admitted on the authority of the " Systematic Catalogue," where they are marked as inhabitants of the metropolitan district. * Eyes hairy. 1. ornatus Meig. 3. 205. ^.

In the Author's and other Cabinets. 718 Meigen's 1st division of Milesia comprises some beautiful species which have not at present been discovered in Great Britain ; they are distinguished by being only slightly hairy, the face is not produced, and the posterior thighs have a tooth beneath : it seems to me that they might be with more pro- priety included in the genus Spilomyia : of his 2nd subsection, with the posterior thighs unarmed, five species are described in his Syst. Bescli., our typical species being the only one found in this country. His 3rd division contains the group Criorhina, which is separated from the rest by a depressed, ge- nerally broad and woolly abdomen. Milesia speciosa is readily distinguished from its native con- geners by the conical forehead. It is now many years since this fine and rare insect was discovered in the New Forest by Mr. D. Bydder, but I took several near Brockenhurst the be- ginning of June 1824, and in a subsequent year the end of May : they fly round the trunks of trees on which they set- tle, as well as upon the slapers from which timber has been felled, and they seem to delight in the thickest parts of the forest, where partial shadows are thrown by the sun from the surrounding foliage. The females are much rarer than the males, of which sex we have given a figure ; and they differ only in the eyes being separated from each other, and in the apex of the abdomen being attenuated and more acute. The continental species resort to the catkins of the willows and the blossoms of the sloe and hawthorn ; they are therefore vernal species, which may be the reason of my not meeting with any in my rambles through France, which have gene- rally been in July and August. Having taken a pair of our insect off the Wood Spurge, Eicphorhia amygdaloides, which was full in blossom at the time, it is added to the plate. 6(jg '■-./■,/vd'.-&^^. 669. PIPIZA BIGUTTATA.

The very prominent horn in front of the head, as well as the remarkably long rostrum which this insect inserts into flowers whilst on the wing, are sufficient characters to mark the genus Rhingia, of which there are but two European species known, and both of them are inhabitants of this country. 1.

Less common than the other species ; it is attached to the same situations ; and has been observed from June to Septem- ber in the neighbourhood of London and in the counties of Devon and Westmoreland. The species figured {R. campestris) has been universally considered in this country as the Conops rostrata of Linnaeus ; but upon consulting his description we perfectly coincide with Meigen, to whom we are indebted for this correction, that the insect figured by Panzer answers best to the definition in the Systema NaturcB. Lychnis dioica, var. diurna (Red Campion), figured in the plate, is a plant to the flowers of which our genus is particu- larly attached. /S3 cfe/.v^c/ifi^^t.^ C^:^.- /6'dC^ 753. SYRPHUS LUCORUM.

Syrphus being an extensive Fahrician group, containing the most heterogeneous types, it is necessary, in accordance with the objects of this work, to illustrate the genus, otherwise as that portion of it which is now indicated by the title of Syr- phus is closely allied to Scaeva (pi. 509), and the typical species of Fabricius being synonymous with Volucella (pi. 452), it might have been very well passed over. The princi- pal distinctions between Syrphus and Scasva are to be found in the form of the head, and the greater length of the palpi. The following list comprises those species most worthy of no- tice, the remainder will be found in the Guide.

In the Author's Cabinet. Syuphus of Meigen is so large a group that it would be very desirable to divide it if good generic characters could be found; but I am not prepared to say that Scseva differs from Syrphus in structure, although the species may be distinguished by their transparent and immaculate wings, and their ornamented and very depressed abdomens ; the clypeus also seems to be less tuberculated and projecting than in the Syrphi. Restricted as the Genus now is, it contains 28 species in- habiting this country, for a list of which I must refer to the Guide. The rare Insect figured may be only a singular variety of S. selenitica wanting the yellow spots on the abdomen : it was taken, I think, in the neighbourhood of London. Two of the species {S. Pyrastri Linn., and S. selenitica Meig., which is probablyonly a variety of the former,) sometimes appear in myriads on the sea-coast, all flying in one direction, and not even avoiding objects that lie in their course. A Lady informed me that on Thursday the 30th of July 1818, which was a very hot day, they quite covered the fishermen's boats at sea off Broadstairs : the next day was cloudy with several slight showers, when scarcely any were to be seen. Saturday and Sunday were warm days, when a few were ob- served flying about, and on the Monday they had entirely disappeared. They were equally abundant at Ramsgate and at the Nore. The larvae of these flies feed on Aphides, and are, I believe, of great value in clearing the Hop-grounds of that destructive insect: they are so admirably described by Rusticus in the Entomological Magazine that I cannot refrain from giving his account of them. " Besides the Lady-bird and its grub, there are two other terrible enemies to the poor Aphis; one of which is a green ungainly-looking grub, without legs, which lies flat on the surface of the leaf, and stretches out its neck, just like a leech, till it touches one of them; directly he feels one he seizes it in his teeth, and holds it up, wriggling in the air till he has sucked all the goodness out of it, and left it a mere empty skin." Equally interesting accounts will be found in the 1st vol. of Kirby and Spence's Introduction to Entomology, p. 257. and vol. 2. p. 275. I may add that I found the larvae of S. Pyrastri in some abundance in the middle of July 1829, on the Sea-cabbages (pi. 352.) growing under Dover Cliffs. The flies appear from June to the middle of October, hovering over flowers in gardens and hedges. I have observed them on paling in the morning at the end of Sep- tember, and the beginning of October I have found the females resting, and the males at the same time on the wing, but much less numerous than the other sex. The Plant is Fragaria sterilis (Barren Strawberry). ^0/ C:./:/yiJ': t,«/>^„ C^.- i 6^ 401. TROPIDIA RUFOMACULATA. Order Diptera. Fam. Syrphidae. Type of the Genus, Eristalis milesiformis Fall.

In the Author's and other Cabinets. Tropidia so nearly resembles Xylota, that I do not think it is natural to place them so far apart as Meigen has done ; in- deed the X. bifasciata of that author has so much the appear- ance of a Tropidia, that I once included it in that genus. The best distinguishing character perhaps is the triangular tooth on the underside of the posterior thighs in Tropidia, which is wanting in Xylota. In their habits also, the T. rufomaculata and X. bifasciata are very similar, for they are frequently taken together ; such was the case at Whittlesea Mere, where on flowers in the ditches Mr. Dale and myself found both of them in abun- dance on the 18th of July; and in an excursion along the banks of the river at Wareham, the middle of last June, amongst other interesting insects, we found the T. rufomacu- lata on umbelliferous flowers. I find that Meigen had only one specimen of T. milesiformis (a male) to draw his description from, it is therefore very possible that my insect may be synonymous with his ; but as he does not notice the following characters, I feel justified in retaining the name I first used in the * Guide.' The third joint of the antennae is rhomboidal with the angles rounded ; our insect has a whitish grey spot near the base of each wing; in the centre of the 4th abdominal segment the males have an ochreous spot ; the legs are black, the basal portion of the 4 anterior tibiae is ochreous, and their tarsi have the penulti- mate joint black. I may further observe, that none of my males are so small as Meigen's ; the female is smaller than the male, and has the base only of the 3rd abdominal segment orange, the wings are nearly transparent, and the 4 anterior tibiae have only black rings towards the apex. Scandix Pecten Veneris (Shepherd's Needle or Venus's Comb) is represented in the Plate. ^ 1 gs (Ji^.^cJ(S:.^-J^^... /, /ci^cf 98. AlERODON CLAVIPES. Order Diptera. Fam. Syrphidse Lat.^ Leach.

Merodon may be distinguished from the extensive genus Syrphus by the regular form of the profile and the sinuated nerve in the wings ; from Tropidia Meig., which it most re- sembles, both in its dentated thighs and the lobed cell of the wings, it is separated principally by the form of the 3rd joint of the antennae ; the clypeus is more produced in that genus, and the species are not so woolly as in Merodon : the same differences, as well as the simple legs of the Helophili, at once separate it from that genus ; and the plumose antennae of Eri- stalis render it difficult to confound it with them. The genus Merodon must be far from common in this country, since we have only discovered one species at present out of 27 described by Meigen; and only 2 specimens of that, both of which are males, taken by Dr. Leach in Spitchwick park, Devon. Never having seen the other sex, I have been compelled to transcribe Meigen's description of it. The few indigenous Liliaceous plants we have in this country may be the cause of our not having at present detected any more speci- mens, for it is well known that our genus is attached to the Narcissi, from which cause one has received its specific name ; and Reaumur {v. 4. p. 572.) has given figures of the larvae, &c. of a species that feeds upon the roots of those plants. It would therefore be worth while to examine meadows where the Narcissi grow spontaneously, when they are in flower ; for if one of the flies were found in the neighbourhood, there would be good reason to suppose they were bred there : and in November the bulbs ought to be examined for the larvae, which in all probability are easily reared ; and additional in- formation respecting the oeconomy of a genus whose habits are so peculiar, would be highly interesting to the Entomologist, and probably beneficial to the Florist. The specimen of Narcissus, Pscudo narcissus (Common daf- fodil), I received from Professor Henslow, who gathered it the beginning of April near Cambridge ; Mr. Dale also showed me numerous specimens soon after, growing at Glanville's Wootton, that were evidently wild. ^2g C^.Af c/: (g^«^ r/^^, /, -m. 1- 1^1^ 429.

These insects are fond of flowers, especially the Thistle, Dan- delion, and Sunflower, on which they are frequently seen, and so much resemble bees in form and colour, that at a little di- stance one may be easily mistaken for the other; indeed I have had some difficulty to convince persons totally ignorant of Entomology, that the Eristales were not bees : and it is further worthy of observation that, when resting, the E. tenax, and probably the whole genus, heave their bodies up and down as bees do, as if they were panting.

The larvae inhabit the nests of Humble-bees, devouring their larvae and pupae, and in the Introduction to Entomology we find the following interesting observations on the subject. " Some sin- gular larvae, with a radiated anus (Pl.xix. f. 1 1 ), live in the nests of humble-bees, and are the offspring of a particular genus of Hies, many of the species of which strikingly resemble those bees in shape, clothing and colour. Thus has the Author of na- ture provided that they may enter these nests and deposit their eggs undiscovered. Did these intruders venture themselves amongst the humble-bees in a less kindred form, their lives would probably pay the forfeit of their presumption. Mr. Sheppard once found one of these larvae in the nest of Apis Raiella, K. but we could not ascertain what the fly was. Per- haps it might be V. homhylans Meig. which resembles those humble-bees that have a red anus." I may add that Mr. J. Cocks of Hish Bickington Devon showed me a similar larva (wanting the anal rays) that he detected in the cells of a wasp's nest Sept. 25th, 1822. It assisted itself in walking with the head, and could turn itself with great facility when laid upon its back. The Plant is Anchusa sempervirens (Evergreen Alkanet).

From the want of male specimens of the other species, I am incapable of ascertaining whether the remarkable structure of the anterior tarsi of M. regius be a specific or generic charac- ter : the hairs on the 2nd joint are glandular at the apex, and the 3rd and 4th joints are terminated by a fleshy substance, which is well adapted to its habits of life, and lead us there- fore rather to consider it as an organization pecidiar to itself. 1.

There is no genus of insects whose habits are more formidable, or whose economy is more extraordinary, than the (Estridce. It has been on a former occasion remarked, that our GEstri were unknown to the ancients, and that the " flying plague " mentioned by Virgil was a Tahanus (Plate 78), an insect as remarkable for the perfect organization of its instrumenta ci- haria.^ as (Estrus is forJ;he absence of those organs. Although the seeds of inquiry were first sown by Malpighi, Vallisneri, Reaumur, and De Geer, Linneeus and cotemporary writers were but imperfectly acquainted with this family ; and it was to the ingenious and masterly investigations of our own countryman Mr. Bracy Clark that we are put in complete pos- session of the habits and economy of the different species, and enabled to examine them scientifically. The European (Es- trida have been sepai'ated by Dr. Leach into 2 genera, in which he has been followed by the most learned Dipterist of the day. The genus QLstrus is distinguished from Gastero- philus by the economy of its larvae and the nerves of the wings, and comprises 4 British insects. 1. CEstrus Ovis Linn. — Clark's Essay, tab. 2.f. 16. to 20. — Do7i. Brit. his. v. 16. pi. 550. 2. Bovis Linn. — Clark, tab, 2.J\ 1. to 10. 3. Ericetorum Leach. 4. pictus Meig. — Nob. The larvae of CE. Ovis live in the frontal cavities of the sheep, change to chrysalides about June, and in August the male flies are found not unfrequently sticking to pales and walls in the neighbourhood of sheep pastures. The larvae of 6E. Bovis, called Warbles, Wormals, &c., live under the hides of oxen and cows, change to chrysalides about the end of June or later, and the fly appears the middle of August. CE. Ericetorum is considered as a variety only of (E. Bovis upon the Continent. We cannot but congratulate our readers on being able to present them with another species of this singular family, es- pecially as it is a fine and handsome insect of great rarity and has never before been figured : as a British insect it is unique, a single specimen having been taken by Mr. Samouelle in the New Forest at Burley Heath, 12th of June, 1823. Of its habits we know nothing ; but it is not improbable that it is attached to the deer, and lives in the larva state probably in the frontal cavities of the head of that animal. The plant is Valeriana dentata (Oval-fruited Corn Salad). t U6 Oui-.-ly '^.f. 20.? New Forest and Belfast. 2. obsoleta Tall. — flava Fah. 3. pallida Tall. Holywood, Mr. Haliday. 4. flava Linn.

In the Cabinets of the British Museum, Mr. Mathews, and the Author. The first specimen I saw of this insect was taken by Mr. Ma- thews early in June, upon Scahiosa succisa, in a chalk-pit near Sittingbourn, Kent. At the end of the same month I took two males and several females upon the plant figured, at the back of the Isle of Wight. The females were generally upon the calyx; which leads me to believe that the curious ovipositor which so strongly marks that sex in Tephritis, is for deposit- ing the eggs between the scales : their horny substance, de- pressed and wedge-shaped form, seem peculiarly adapted to such an operation. As they were very wild, I could never ap- proach near enough to them in fine weather to ascertain the fact; the proof must therefore be left for some more fortunate observer. Although only four species have been recorded as natives of Britain, the following list, arranged according to Meigen, will show how rich we are in this beautiful genus : the four with * I do not possess.

Meigen having engaged to describe the European Diptera, and having already published three volumes of his excellent work, I have always been desirous rather to follow than to anticipate that celebrated entomologist in his arduous under- taking; I should not therefore have published this genus at present, had I not considered it an example of Latreille's genus Scatophaga, and had proceeded too far under that impression to stop its publication, when Mr. Samouelle pointed out to me a specimen sent to Meigen by Dr. Leach, which was returned to the British Museum with the names I have adopted. The specimen sent was the contrary sex to mine, and is exceedingly injured, as many of the insects in the Museum are, by the bot- toms of the drawers having been unfortunately made of cedar, from which a resinous substance is constantly distilling, some- times making its appearance inside, at others outside the drawers : this inconvenience I am happy to learn will soon be remedied, and I should not here have made this digression did I not hope it might guard others from the like misfortune. But to return : of the identity of the genus, which I believe is unpublished, there is no question ; and there appear to be good reasons for dividing it from Scatophaga; for besides differences in the trophi and antennae, the tibiae being only woolly without any bristles, and the basal joint of the posterior tarsus, which is not longer than the 2nd, rather compressed, and a little bent, at once distinguish it from that genus. Of the species I cannot be so certain, the resm having destroyed the colour, and altered the appearance ; but from a memoran- dum in Dr. Leach's hand- writing, stating that the specimens were taken at Swansea and Yarmouth, it is evident H. ustulata is a sea-coast insect ; and my friend J. C. Dale, Esq. took his specimens at Christ Church, Hants : and about the end of August 1821, during some tremendous gales, I found several upon the extensive and exposed sand-hills stretching along the coast to the south of Calais. There appear to be three other species of Helcomyza inhabiting Britain, one only of which was named by Meigen at the same time as the species under consi- deration. Glaucium lutenm (Yellow-horned Poppy), which was in flower at the time, is figured with the insect. 62, 621. LUCINA FASCIATA. Order Diptera. Fam. MuscidtE. Type of the Genus, Lucina fasciata Meig.

In the Cabinets of Mr. Haliday, the Author, 8iC. I AM induced to illustrate this genus and give a figure of the male of this rare insect, in consequence of Meigen having seen the female only, which sex is represented in his plate ; and Macquart's figures are so bad that they are utterly useless. In some respects Lucina resembles Cordylura (pi. 4-85), the abdomen of the male being incurved and horny ; nevertheless I have little doubt that it is more nearly allied to theTetanocerae and to Actora (Helcomyza, pi. 66), close to which Meigen has placed it. Lucina Jasciata is the only species known of the genus, and had only been found at Marseille until it was discovered by my friend Mr. Haliday on the sands at Portmarnock near Dublin, where he took both sexes in June and transmitted me a very fine series. It may be observed that the seta of the antennae is not naked as stated by Meigen and Macquart, and the abdomen appears to be 7-jointed in consequence of a transverse suture near the base. The shortness of the basal joint in the hinder tibias, the inclination of the third and fourth longitudinal nervures at the apex of the wing, the remarkable horny ball terminating the male abdomen and the truncated tube of the female, are cha- racters that distinguish Lucina from neighbouring groups. The Plant is Stellar ia nemorum (Broad-leaved Stitch wort), communicated by J. Walton, Esq., from Knaresborough. /^ \ I 'J6^:-^Qfi$.,-«i.cj:^, /./ssg Av^j; 725. PLATYCEPHALA PLANIFRONS.

Planifrons Fab. — Curt. Guide, Gen. 1323. 1. In the Author s and other Cabinets. There are so many striking characters which separate this group from all others, notwithstanding a general similarity of appearance, that it may be as well to enumerate them. The head is broader than the rest of the body, the crown is hollow, and the forehead projects, forming a shield-like mar- gin ; the abdomen is narrow and shining; the legs are not at all bristly ; the hinder thighs are thickened and their tibiae very much bowed at the base to receive the keel of the thighs; the second joint of the antennae is large, the upper portion lapping over the third joint which has a somewhat transparent dot on the side, which does not seem to have been noticed by Meigen, and the seta is Inarticulate. I could not discover either maxillary appendages or a tongue. Some of the above characters will distinguish Platycephala from Trigonometopus (Pi. 689) and Tetanocera, as well as from Eurina, which is confounded with it in many collections. Two species of Platycephala have been found in England. 1. planifrons, Fab. — Curt. Brit. Ent. pi. 725. — culmorum Fall.

Macquart has separated Trigonometopus from Tetanocera in consequence of consider- able difference in the relative proportions of the joints of the antennae, the 2nd joint being equal to, or greater in length than the 3rd in the latter genus, and shorter than the 3rd in the former. There is still so great a variety of character in the genus Te- tanocera, that most probably Desvoidy's groups will be event- ually adopted. Some species have the 2nd joint of the antennae much shorter than others, sometimes the seta is plumose, at others naked, and the transverse nervure is straight or waved in different species : such characters might certainly be well employed in the formation of sections, which are of great value in the study of Natural History, as they lead to a close examination and philosophical inquiry into the structure and affinities of allied species ; but all the advantages thus obtained are too frequently more than counterbalanced by the anxiety to give names to trifling groups, which were never destined by Nature to hold the rank of Genera. The interesting insect before us was not known to be a na- tive of this country until Mr. Dale met with three specimens in the neighbourhood of Glanville's Wootton; they were taken off some rushes growing in a gravel pit the end of May, and from them he has liberally supplied my cabinet. The Plant is Aira (Deschampsia Beauv.) caspitosa, Turfy Hair-grass. J^jo / :-'A ^.v.^^^ '_ 'i^. /■yz/\€,i^'ui^ 6^^^ /6'SS 1^ /f 3 3 545. HELOMYZA RUFA. Order Diptera. Fam. Muscidae.

In the Author's and other Cabinets. The names of some specimens transmitted to M. Meigen by Dr. Leach having been transposed and illegibly written, led to an error when Actorawas published in this Work, which was then given as Helcomyza ustidata (fol. 66)^ and Meigen's vols, containing those genera not having been at that time published, 1 had no means of detecting the mistake. Helomyza is characterized by the bristly costa to the wings ; and the peculiar manner in which the intermediate tibiae are armed with bristles will be found valuable in distinjTuishing: them. They are partial to damp situations, but not uncommonly enter houses. The following British species may be thus arranged. A.

In the Author's and other Cabinets. There are several characters which distinguish Heteroneiira from Agromyza and congenerous groups, as the slender linear abdomen, the large second joint of the antennae, the situation of the seta and the neuration of the wings. They are said to affect grassy situations : the species are rare in Germany, and one only has been detected in France. The only one which is known to inhabit this country is the species figured ; and having taken the first specimen in Scotland in July 18^5, I named it at that time Scotica; but Meigen having since de- scribed it, my name must fall. On the 5th of July, 1836, after a most awful thunder-storm at Ingleton in Yorkshire, I took a female Heteroneura on the inside of the window of the inn.

I BELIEVE that hitherto nothing has been recorded of the 09co- nomy of these insects; it is therefore with great pleasure that I can give a short account of the species figured : for this infor- mation as well as for specimens of the fly I am indebted to my friend the Honourable C. A. Harris, who informed me that in examining the receptacles of the Pi/rethrum inodorum he dis- covered small maggots and pupae in the centre of a considera- ble number of them, and that eventually one little fly was pro- duced from them. I afterwards had the pleasure of investiga- ting the subject with him, and a great portion of the flowers we gathered in a field near Heron Court contained larvae or pupae, seldom more than one in each ; they produced flies from the besinning; to the end of October, Another minute species, which I think is the P. nigra of Meigen (v. 6. p. 191. n. 7.)? was sent to me by a lady, who found the pupae on the underside of the leaves of the Colum- bine (pi. 392.) the 7th of November, and they hatched the fol- lowing May.

Ornithomyia is one of the groups formed from Linnaeus's genus Hippobosca, but from that and Haemobora our genus is distinguislied by the claws, the more developed antennse, and the nervures extending to the mferlor margin of the wings, and from the other genera by its ample and rounded organs of flight. The Ornithomyiee inhabit birds, living amongst the feathers. I have only found them on the Rook, but the Honourable C. Harris observed a very small species on a Buzzard, I think, which was shot near Heron Court; Mr. Cocks detected a species (O. viridis?) on the Moor Buzzard, and Mr. Frankum showed me some specimens of O. viridula ? which were found on a Hawk ; I suspect, however, that birds of prey are not the natural resort of the Ornithomyiae, but that when a quarry is killed by a Hawk, these parasites probably leave the dead bird to prey upon the living one. The following are British species ; they all incline more or less to green when alive, and it is probable the eyes and ner- vures of the wings fade also in old specimens. 1. aviculariaZ//?iw. — Leach in JVern.

Having upon a former occasion made some remarks upon the Order Omaloptera and taken a view of the structure, which at that time could not be fully illustrated in consequence of the rarity of the species then investigated, we shall here avail our- selves of the opportunity of explaining the figures that we have now the pleasure of laying before our readers, by giving a detailed explanation of them. The antennae (fig. 3 & 3*) are very singular in their con- formation, and may be called auriculate; the process or style inserted in the globose base has not been before noticed ; and in the genus Melophagus it is still more extraordinary, being 4-cleft and arising out of an aperture in the globose portion of the antenna, which is hollow. Fig. 4. shows a great portion of the underside of the head, forming what I have called the mentum ; it conceals and pro- tects the trophi when at rest, at which time the ovate base, fig. 2 h, rests within the spot with a row of bristles immedi- ately above the figure 4 ; the bristles at the anterior angles are peculiar; the maxillae (d) are similar to those of the neigh- bouring genera. Fig. 2. exhibits the trophi, takeh out, with the part attached to the head, which from its elasticity and length enable the insect to exsert them the whole length of the lip beyond the mentum ; at the base arise 2 curved bristles, probably to regu- late the direction of the tongue, &c. when in action. Fig. 1. g, c, b. are the trophi detached, better to show their form. The wings from their disproportionate width cannot, we conceive, enable the insect to fly, but may be useful in assist- ing it, when accident has thrown it upon its back, to recover its natural position. It must be confessed, that the poor House- Swallow, whose nest and feathers are infested with this parasite, which (by comparison) is a monster in size as well as in form, is by no means to be envied ; and the exhaustion occasioned by supply- ing nutrition must be very considerable where these insects abound in an individual, as is often the case.

Li the Author's and other Cabinets. The curious antennae of Melophagus Ovinus have been already alluded to in folio 122, and we wish now further to call the attention of the student to their remarkable structure, as they appear hitherto to have escaped observation, and they are scarcely analogous to any other antennae unless it be to those of the LihellulidcE. The antennae are of a leathery substance, somewhat globose covered with short hair, being hollow part of the way down, at the bottom of the cavity is attached a thin process, cleft at the apex and probably moveable ; but from its minuteness it is difficult to ascertain whether it can be ex- serted and withdrawn at the will of the animal. The trophi exhibited at fig. 2. are particularly long and very much bent ; although this insect is one of the few that is apterous in both sexes, the thorax is slightly produced where those organs are attached in the neighbouring genera. Our insect is one of the many that attack sheep, and is found I believe all the year round, our friend Mr. Carpenter having sent us some as early as March. In the 1st volume of the Introduction to Entomology we find the following passage relating to our subject. " But of all our cattle, none are more valuable and important to us than our JlocJiS ; to them we look not only for a principal part of our food, but also for clothing and even light. Thick as is their coat of wool, it does not shield them from the attack of all-subduing insects : on the contrary it affords a comfortable shelter to one of their enemies of this class, regarded by Linne as a species of Hippobosca, but properly separated from that genus by Latreille under the name of Melophagus. This is commonly called the sheep- louse, and is so tenacious of life that we are told by Ray it will exist hi a fleece twelve months after it is shorn, and its excrements are said to give a green tinge to the wool very difficult to be discharged." The plant figured, Hydrocotyle vulgaris (called Pennyrot, Sheep-killing Penny grass. Water Pennywort, White-rot, &c.) is supposed by some to cause the rot in sheep. 2// C%/.- /y c/S^^Uuf C^f/f: /. iSiJ^ 277. NYCTERIBIA LATREILLII. Order Omaloptera. Fam. Nycteribidae Leach.

Head resting upon the back of the thorax, to the anterior margin of which it is attached at the point, a. Jig. 7, it is very small convex and subovate (2). Eyes and Ocelli none? Thorax undivided, suborbi' cular, with a groove down the middle to receive the head. Wings none, but there is a narrow appendage ciliated with short strong bristles, on each side at the base of the middle pair of legs (9). Ab- domen conic-depressed, composed of 6 ciliated joints in the male, the last joint hollow beneath, producing a style in the centre and termi- nated by 2 incurved pilose lamince. Legs compressed, attached to the sides of the thorax, the anterior pair inserted rather above. Coxae short (8 a). Thighs broad ovate (b). Tibiae short, obovate, and pilose, with robust bristles on the inside (c). Tarsi long, 5-jointed, basal joint curved, as long as the tibice, 3 following obtrigonate, bth very much dilated at the apex (d). Claws bent recurved or dilated at the base. Pulvilli slender (8, afore leg). Fig. 2 represents the head, in profile, the underside resting upon the back, in repose ; the processes called maxillce and the trophi are in their natural position. Fig. 7 is the thorax, with a small portion of the abdomen, the spot at, a, being the point of attachment of the head, and the insertions of the coxce are marked by b, c and d, and at 9 are the ciliated appen- dages, which may cover spiracles for breathing, organs for hearing, or they may be the analogue of rudimentary wings.

I HAVE been unable to ascertain so much as I could wish con- cerning these extraordinary insects, from the minuteness ot the specimens which my friend Mr. Jenyns kindly submitted to my inspection. Having been led to draw conclusions rather at variance with the ideas of Colonel Montague and Dr. Leach, I shall proceed to state them. The former gentleman, whose interesting Paper in the Linnean Transactions well deserves to be perused, supposed that the Nycteribia must turn on its back to apply the mouth to the skin of the bat ; but the head appears to me to be so articulated that it can, I suspect, porrect it, or even bend it down, and the rostrum can most likely be raised to a considerable angle from the head. I will not how- ever insist further upon this point, never having seen the ani- mal alive, and especially as there is an analogous instance in the true Cimex, and probably in all the others with long la- biums. I have observed that the C. lectularius does not (and I believe cannot) insert its rostrum into the object it stands upon, for it erects its trophi above the head so as to form a right angle with the back. Dr. Leach was no doubt mistaken in considering the coxa to be the first joint of the femora, as well as in taking the basal joint of the tarsi for a second joint of the tibiae; these errors how- ever I do not notice because I take any pleasure in lessening the merit of others, but only to guard the student against mis- construction. The only two species of Nycteribiae known in Britain are 1. N. Hermanni Leach, Enc. Brit. Siipp. — biarticulatum i/(?r?w. — Leach, Zool. Mis. 3. 55. tab. 144. mas. f em. Siwdfoot. — Vespertilionis Mont. Linn. Trans, v. ll.p. H. It inhabits the greater and lesser Horse-shoe Bats. It is larger than the following species; and 1 am inclined to think, from the size of Latreille's N. Vespertilionis, and the form of the thorax in the Linnasan P. Vespertilionis, that they belong to this species. 2. N. Latreillii Leach. — Curtis Brit. Ent. pi. 277. Inhabits Vespertilio murinus (the Common Bat). The fol- lowing memorandum was transmitted with the insects by the Rev. L. Jenyns : " I cannot speak with certainty as to the spe- cies of Bat to which these parasites were attached, since they were found in a vessel of spirits containing several different kinds of Vespertilionidse ; 1 can only say that the Bats were all received from Northamptonshire." The plant is Conyza squarrosa (Great Flea-bane). SYSTEMATIC INDEX. Order 13. DIPTERA. Vol. VIII. Plate. Fam. CULICID.E. 662. Culex guttatus . . 663. Anopheles bifurcatus Fam. TIPULIDtE. 664.
