PRINTED BY TAYLOR AND FRANCIS, RED LION COURT, FLEET STREET. WAR PREFACE. Tue First Part of the ‘Catalogue of British Hymenoptera,’ pre- pared by Mr. Frederick Smith, and published by order of the Trustees in the year 1855, contained an account of all the species of British Bees then known, with notes on their distribution and habits. Since that time the interest felt for the insects of this family has continued, and consequently many important additions to our knowledge of the species and their economy have been made, so that the issue of a second edition of this part in the form of a separate volume seems to be fully justified. ALBERT GUNTHER, Keeper of the Department of Zoology. British Museum, Dec. 1876. PS! Although since the publication of this volume fourteen years have elapsed, during five of which it has been out of print, the demand for copies continues so as to justify a reprint. No doubt, if the author’s life had been spared, he would have brought the contents of the volume to the level of the latest advance of our knowledge of the subject. As it is, it was considered preferable to leave Smith’s work without making any additions; entomologists may readily supplement it by consulting Mr. Edward Saunders’s papers published in the ‘ Transactions of the Entomological Society ’ for 1882 and 1884. ‘The present issue of the volume, therefore, is an exact reprint of that published in 1876, with the exception of a few misprints in the original, which were pointed out to me by Mr. W. F. Kirby, and which have been corrected. A. G, British Museum (N. H.), Feb. 4, 1891. INTRODUCTION. Tux total number of British species of Bees known at present is 211, which number only slightly exceeds that contained in the first edition of this work, some of the forms therein enumerated as distinct species having proved to have been founded on sexual cha- racters. Ten species are entirely new additions to this part of the British fauna, whilst two, formerly believed to be British, have been omitted (Sphecodes fuscipennis and Andrena kirbyi). Other errors have been corrected and the synonyms carefully revised. All the types of Kirby’s Monograph have been reexamined, and the species contained in the Stephensian, Curtisian, Linnean, and Banksian col- lections have been again referred to. Whenever practicable, the descriptions have been prepared from specimens in the finest possible condition ; and, in accordance with the former edition, French measurement has been used. When both sexes have been described as distinct species by an author in the same work, the specific name given to the male has in every instance been adopted. The letters B.M. indicate that the species is represented in the collection of the British Museum. FREDERICK SMITH. British Museum, Nov. 1876. see SYSTEMATIC INDEX. Fam. ANDRENID&. Subfam.

In August 1860 I took five specimens of this local insect; it frequented the flowers of the wild scabious (Scabiosa arvensis) in 7 Since edrena hattorfiana, on wanoi insect it is probably parasitic, as I have sincerenserved ther “or ny. It was first taken in this country, believe, by Dr. aeacn’.- wveyoushire, where it has since been found by Mr. Parfitt near Exeter, and by myseit.at Woollacombe sands, near Morthoe, North Devon, This is the largest species of Nomada found in this country. 9.

B.M. This speciesis parasitic on Andrena argentata, and appears inAugust; it was first discovered at Sandhurst, and has since been taken at Weybridge in some numbers, and very abundantly at Bournemouth. Dr. Nylander says it is found both in Denmark and Sweden. Thomson thinks it may be the alboguttata of Herrich-Schiiffer ; but if his description is correct, it certainly cannot be. I have never seen a continental specimen. 11. Nomada xanthosticta. N. atra, antennis subtus scutellique punctis ferrugineis ; abdomine rufo, segmentis secundo et tertio maculis duabus flavis.

BM. This is a rare species ; it appearsin July. What bee it is parasitic upon is not known; but I once took two or three females in Fern Wood, near Ilfracombe, within a few yards of a colony of Halictus minutus. It was first discovered by the Rev. Mr. Rudd, at Yarm, Yorkshire ; Mr. Bridgman has taken it near Norwich. 12. Nomada furva. NV. atra, scutello rufo-bimaculato, abdomine rufo-cincto. Mas abdomine flavo-maculato. Nomada furva, Panz.

This is the smallest species of the genus known; Fabricius appears to have thought himself justified in consequence in giving it a cha- racteristic name, at the same time quoting Panzer’s name, which has the priority and must be retained. This little bee is parasitic upon Halictus morio, and probably also upon H. minutus; Mr. G. Newport found numbers in the cells of one of the species of Colletes. 13. Nomada flavoguttata.

B.M. The male described is a highly coloured example; the spotting of the abdomen varies greatly ; and the scutellum is sometimes more or less ferruginous, and, in small specimens, occasionally black. The species is very local and rare; it was first discovered near Klackwater, Hants, where a few specimens were taken; it has sub- sequently been found more plentifully near Carlisle. It frequents the ragwort (Scnccio jacobea), and is found in July and August. wt 2. NoMADA. i12: 15.

In this species the tips of the posterior femora are produced above into a blunt spinose process; it is unique in the collection of the British Museum, and is supposed to have been captured in Deyon- shire at Kingsbridge. I have not seen it in any continental collec- tion. It is quite distinct from NV. rufa of Rossi. 16. Nomada fabriciana.

This species of Nomada is the parasite of Panurgus banksianus, and is always to be found with colonies of that insect during the months of June and July. Kirby suspected that his A. quadrinotata was the male of this species; but the insect was not found commonly at Barham. At Hampstead it has occurred in great abundance. It is local, but widely distributed ; it has been found at Bournemouth, Ventnor (Isle of Wight), Sidmouth, in all the home counties, and in Yorkshire. 17. Nomada germanica.

BM. This species is parasitic upon Andrena fulvescens, and sparingly found in the London district. At Hawley, near Blackwater, it was found in immense numbers, frequenting a large colony of the A. fulvescens ; it is also plentiful at Bournemouth, Although N. atrata has been taken at Arundel, and one or two at Kingsdown, near Deal, unaccompanied by other normal examples of V. germanica, I believe it is a rare and remarkable variety of the male of that species. It has also been taken at Red Hill, near Reigate. 18. Nomada solidaginis.

Length 23—4 lines.—Black ; the clypeus, sides of the face, the labrum, mandibles, and the scape in front yellow; the face has a silvery white pubescence ; the flagellum rufo-testaceous beneath 28 APIDE. Thorax—the collar, tubercles, a lunate spot beneath them, the tegule, and scutellum yellow ; the legs pale ferruginous, the ante- rior and posterior coxze yellow in front, the intermediate pair have usually a minute spot at the sides and another on the pectus in front of each ; the posterior femora black at their base, the anterior and posterior pairs usually rufo-testaceous, but sometimes black, the tibie and tarsi varied with yellow ; the wings subhyaline, their apical margins faintly clouded.

B.M. Var. 3. The band on the fourth segment interrupted. Var. y. The basal segment having two minute yellow dots. Var. 6. Margins of the segments of the abdomen rufo-piceous. This is the most variable species of the genus, both in size and coloration ; it is the parasite of Halictus leucozonius, and probably also of H. cylindricus. It is found in considerable numbers on wild thyme and on the ragwort (Senecio jacobea) in July and August, and sometimes also as late as September. The male seldom varies in its colouring, a red variety being a great rarity, whilst the female runs into endless variations of colour and size. 19. Nomada jacobee.

B.M. Var. 6. Abdomen having all the bands, except the apical one, inter- rupted. This is probably the Nomada interrupta of Panzer. This species is at times very plentiful in certain localities, but it is a local insect ; it usually appears in July, and is found in August and September. I once found it entering the burrows of Andrena fulvicrus, in August, at Sidmouth; but I suspect it is usually para- sitic upon species of Halictt. Kirby describes an insect which he took in spring on the flowers of the gooseberry ; unfortunately only a portion of his type remains. LN. jacobec he could not have found at the time he mentions; I believe his insect to be a male of N. succincta ; it is certainly a larger bee than WV. jacobew. Kirby’s A. flavopicta is undoubtedly the female of Panzer’s insect. This bee is frequently found on the ragwort ; but it also frequents the Scabzosa arvensis, on which flower I took it at Lundy Island. 20. Nomada lineola.

Thorax—the tubercles and tegulz, also sometimes two minute dots on the scutellum, yellow; beneath, as well as the cox and femora, covered with a hoary pubescence ; the femora, tibis, and tarsi ferruginous, the former black at their base beneath, and the posterior pair also black within; wings as in the other sex. Abdomen—the three basal segments having interrupted yellow fasciz, the three apical fascie uninterrupted, the seventh segment yellow; the fascia on the fourth segment attenuated in the middle ; the three basal segments have the lateral yellow stripes more or less pointed within; beneath, the segments have trans- verse broad yellow stripes. B.M. Var. 8. The apical margin of the basal segment of the abdomen fer- ruginous, and having two yellow spots. This insect appears in May, and is generally distributed. The female varies greatly both in coloration and size: the male seldom varies ; it closely resembles the same sex of J. alternata, but it has the legs variegated with yellow, and the tegule of the wings bright yellow. On examining Kirby's type specimens it becomes per- fectly obvious that his Apis capre and A. subcornuta ave only small varieties of NV. lincola; the names N. cornuta and N. subcornuta were ill chosen, as the horn on the lip is common to so many species. 21.

It was formerly very abundant about Highgate Archway, but is now scarce near London, a colony of Hucera having been destroyed and the ground built upon; it is found at Southgate, and very abundant below South- end. It has not been received from the north of England or from Ireland. 22. Nomada alternata.

Length 4-5 lines.—Black ; the anterior margin of the cly- KZ 132 APID. peus, the labrum, mandibles, and antenne ferruginous. Thorax— the collar on each side, the tubercles, and two spots on the scutellum yellow ; the tegule and legs ferruginous ; the coxe and femora towards their base black; the wings subhyaline, their apical mar- gins clouded, the nervures ferruginous. Abdomen—two minute spots on the basal segments, an interrupted fascia on the two fol- lowing, on the fourth an entire fascia, and on the fifth a large quadrate spot yellow ; there is usually a minute spot on each side of the quadrate one; beneath, the third and fourth segments have usually a yellow fascia, and the second sometimes two minute yellow dots. BM. Var. 2. The basal segment of the abdomen immaculate, and the spots on the scutellum reddish yellow. Male. Length 33-5 lines.—This sex very closely resembles the female, but has the scape in front, the anterior margin of the cly- peus, the labrum, and mandibles yellow; the face has also a silvery-white pubescence ; the tubercles yellow; the tegule ferru- ginous, sometimes dashed with yellow; the wings and legs as in the other sex; the fasci# on the abdomen are broader, the first three subinterrupted ; beneath, the second and three following seg- ments have broad yellow fasciz, the first usually interrupted, the apical segment yellow. B.M. Var. 3. The basal segment of the abdomen immaculate. Var. y. Two minute spots on the scutellum. This species is found throughout the United Kingdom, and one of the most abundant ; it appears early in the season, frequently in the first week in April. One peculiarity is connected with it: during a very fine autumn a few make their appearance. I have taken it on the 10th and 15th of September on Shirley Common; one or two of the spring species of Andrenidz also appear in such seasons. This Nomada is parasitic on Andrena nigro-enea and also on A. atri- ceps ; I have also observed it in the burrows of Zucera longicornis. Kirby does not appear to have found the species at Barham, or he would probably have united the sexes. It will be observed that continental authors adopt the name given by Kirby to the female; this is contrary to an almost general system adopted in other orders of insects. The male is described as the fifth species, the female as the tenth in the ‘ Monographia Apum Angliz.’ 23. Nomada succincta.

Thorax—the collar, tubercles, tegule, two spots on the scutellum, one on the postscutellum, and a dot on each side of the metathorax yellow ; the legs ferruginous ; the coxe, trochanters, and femora beneath at their base black, the posterior pair also more or less black within ; the wings fulvo-hyaline, their nervures pale fer- ruginous. Abdomen—each segment having a yellow fascia, the first usually interrupted, the two following attenuated in the middle. BM. Male.—Very closely resembling the female, but having the clypeus anteriorly, the sides of the face, the scape in front, the labrum, and mandibles yellow; the latter ferruginous at their tips; the scape black above, and the four or five basal joints of the flagellum black above; the head aad thorax have a thin hoary pubescence; the anterior coxze and the tibie in front, and a spot on each side of the breast in front, yellow ; an interrupted line on the collar, the tegule, and two spots on the scutellum yellow; wings subhyaline, the neryures pale ferruginous, the apical margins faintly clouded as in the other sex ; the abdomen as in the female. B.M. This species is abundant in all parts of the country, and appears in April. It is not subject to vary greatly, but the females sometimes have an uninterrupted yellow band on the basal segment of the abdo- men, and the two minute yellow spots on the metathorax are occa- sionally obsolete. An entire fascia on the basal segment of the abdomen is sometimes found in the males. Genus 3. EPEOLUS. Apis (pt.), Zinn. Syst. Nat. i. 953 (1766). Nomada (pt.), Fabr. Ent. Syst. ii. 545 (1793).

Head transverse, the ocelli placed in a curve on the vertex; the labrum transyerse-ovate, the anterior margin subemarginate, with a minute tooth in the centre of the emargination, the angles produced ; in the middle, two minute teeth placed in a line with the angles of the emargination. The labial palpi 4-jointed, about one fifth shorter than the labium ; the two basal joints elongate, the first joint one third longer than the second, the two apical joints minute, placed at the apex of the second joint; the paraglosse short and lanceolate. The mavillary palpi 1-jointed, the joint ovate and minute. The superior wings having one marginal and three submarginal cells, 134 APIDZ. the marginal cell elongate-ovate, slightly narrowed towards the apex; the first submarginal cell nearly as long as the two following, the second much narrowed towards the marginal, and receiving the first recurrent nervure a little beyond the middle; the second sub- marginal also much narrowed towards the marginal cell, and receiv - ing the second recurrent nervure a little beyond the middle. The Jegs have the calcaria and claws simple. Abdomen oblong-cordate. The genus Hpcolus is geographically widely distributed, being found in all the quarters of the globe. Only two species are known that are Asiatic; two or three have been found in Africa; and about six in South America. The metropolis of the genus will pro- bably prove to be North America; at least twelve are described from that country at present, and a greater number will shortly be added to the list by Mr. Cresson. In this country only a single species has been discovered, Hpeolus variecgatus. Itis parasitic upon Colletes daviesana, C. fodiens, and, I believe, also upon C. marginata : I took a number in company with that insect, all being of a smaller size than those found with the other two species of the genus. 1.

This sex only differs from the female in having the labrum usually and the scutellum always black ; the cox, trochanters, and base of the femora are usually black. B.M. This very prettily coloured bee is local, being only found in locali- ties where species of Colletes have established colonies; it is a summer insect, being frequently found on the ragwort (Senecio jacobea), and also on the mouse-ear hawkweed (Hieracium pilo- sellum), in July and August. It has not been taken in the imme- diate neighbourhood of London, but is common in tke lanes of Kent, Surrey, and Hampshire; it has also been taken at Barmouth in Wales, and is common in parts of Suffolk and Norfolk; it has not been received from Scotland or Ireland.

Abdomen conical, » truncate at the base. The genus Welecta contains, at present, a small number of species, not more than twenty being known, the majority being European ; one species comes from Algeria, and four from Chili; none have yet been found in North America. In this country we have two species, both being handsome insects, and both parasites on species of the genus Anthophora, from the cells of which they have been 136 APID&. frequently bred. The Melecte are frequently infested by the larvze of Meloé; on one occasion WM. armata was found close to burrows of Anthophora, so covered with these larve that the bee was com- pletely coated over with them and unable to take flight. It is quite probable that the larvee of the beetle are as often carried into the burrows by the parasite as by the working bee. 1. Melecta luctuosa.

B.M, This bee is parasitic on Anthophora retusa ; it is not usually found so early in the season as the Melecta armata. I have never found it with A. acervorum. It isnot uncommon on Hampstead Heath in © May, but is a local insect. Dr. Nylander has examined the Fabri- cian type in the Museum at Stockholm, and informs us that it is identical with this species. 5, ——— ae 4, MELECTA. 137 2. Melecta armata.

Abdomen—the base thinly clothed with cinereous pubescence, and having on each side a tuft of nearly white pubes- cence, a similar tuft on the second, and two minute white spots on each of the following segments placed laterally ; and sometimes the ‘fifth segment is also spotted. B.M. The female of this species is subject to great variation in the colour of its pubescence, and Newman gave specific names to some of these varieties. The sexes are not subject to great difference in size ; but occasionally, as in almost all species of parasitic Apidae, very small starved examples are taken; one of such only measuring four lines 138 APIDZ. is in my possession. The species is parasitic upon Anthophora acervorum ; Chrysis ignita has also been reared from the cells of that bee. I have never taken either of the species of Melecta on a flower. B.

Abdomen oblong, truncate at the base. The number of species at present known is twelve ; six are found in Europe, one in Siberia, two in India, one in North China, and two in the United States; others will doubtless be found in the latter country. ‘The British species are widely distributed, extend- ing northwards to Denmark, Sweden, and Finland ; they are para- sitic on different species of bees belonging to the genus Osmia. 1.

This is a very local insect; it is parasitic on Osmia fulviventris, and probably also on O. aurulenta; it is found occasionally in the flowers of the mallow (A/alva sylvestris). I have taken it at Kings- down, near Deal; at Weybridge; Birchwood, Kent; Blackwater, Hants ; Ilfracombe, North Devon, and at Sidmouth, South Devon. It has also been taken near Clifton, Bristol, at Norwich, and by Mr. Kirby at Barham. 2. Stelis pheoptera. S. atra, punctulatissima, albido subpubescens, alis fusco-hyalinis, ano rectangulo.

This species is very local, and parasitic on Osmia fulviventris ; it, like the previous insect, is found occasionally in the flowers of the mallow. It appears in June, and may be taken during July and August, but is much rarer than S. aterrima. It was formerly taken about Battersea, Hammersmith, and Fulham, but has not been met with for some years past; Mr. Parfitt has taken it near Exeter ; and Mr. Kirby found it at Barham. 140 APID, 3.

The abdo- men shining, closely punctured, but not so strongly as the head and thorax ; the basal segment has on each side an ovate yellow macula, and the three following an Suge ovate stripe, pointed within ; the apex rotundate. Male. Length 3 lines.—Closely resembling the female, but differing in having an ovate macula on the two basal segments of the abdo- men, the third has a narrow streak on each side, the fourth two spots on each side, and the fifth a single spot. This species was bred by Dr. Thwaites from the nest of Osmia leucomelana ; subsequently I took two specimens at Hawley, near Blackwater, ‘Hants, where the same species of Osmiais found ; I also took a single specimen at Sidmouth, in August 1872. It is very like S. minuta of St .-Fargeau, from which it differs principally in the form of the scutellum, the posterior margin being subangular and somewhat produced over the metathorax ; in S. minuta it is rounded, Dr. Sichel sent specimens of S, minuta for comparison ; the differences are slight, but appear to be specific. The species is very rare, not more than half a dozen specimens having been taken in this country. Genus 6. CELIOXYS. Apis (pt.), Lenn. Syst. Nat. i. 953 (1766). Anthophora (pt.), Fuér. Syst.

Head transverse, as wide as the thorax ; oceldi in a triangle on the vertex ; the eyes elongate-ovate, pubescent ; antenne filiform ; the labial palpi 4-jointed, the two basal joints elongate, the second a little longer than the first, the third and fourth minute and articu- lated near the apex of the second joint. Mavillary palpi short, 3- jointed, the basal joint shortest, the second thicker and the apical one ovate. The labrum elongate, the sides paraliel, its base produced at the Jateral angles. Thorax subglobose, the scutellum armed laterally at its base with a curved acute tooth ; the anterior wings with one elongate marginal cell rounded at its s apex, two submarginal 6. C@ELIOXYs. 141 cells, the second receiving both the recurrent nervures, the first near its base, the second near its apex. Abdomen conical, its base trun- cate and its apex acute; in the males the apex is obtuse and toothed. The claws simple in the females, and bifid at their apex in the males, which have the anterior coxz toothed. This genus is one of considerable extent; about sixty species are known, only six of them being found in Great Britain ; some species are widely spread throughout Northern Europe, being found in Russia, Sweden, and Siberia. Twelve species are known from Africa, having been found in Guinea, on the Gambia, in Angola, and at the Cape of Good Hope; about twenty are Asiatic; and thirteen are known from 8. America, and rather more than that number from N. America. It is singular that this genus has not been discovered in Australia, since the genus Megachile, upon which it is principally parasitic, is common in that country; some of the species are parasitic on species of Saropoda. These bees by no means confine their attacks to the nests of one species of Megachile: C. vectis is frequently parasitic on M. maritima, but it also attacks M. willughbiella ; C. simplex is at one time parasitic on WV. circumcincta, and at another on M. argen- tata. Great difficulty attends the discrimination of the males of the different species, whilst the differences in the form of the apical ventral plates of the abdomen of the females render their indentifi- cation comparatively easy. Much confusion has arisen in the synonyma of this genus, in consequence of different authors having been unable to distinguish the typical species described by Linnzus, each sex being accounted as distinct by that author. The types of Linnews being preserved in his cabinet in the collection of the Linnean Society, I hope by a careful examination of them to remove the difficulty. Foerster has thrown the genus into a chaos of con- fusion by his system of making species upon the slightest differ- ences. In all species of bees, but more particularly such as are parasitic on more than one species, great discrepancy in size and also in the development of parts must be always taken into con- sideration. The most variable species of the genus found in this country is C’. simplex, which I have found to vary in length from 33 lines to 63 lines; the smaller examples have the lower valve of the anal segment of the abdomen very narrow and acute at the apex, but a gradual approach to this is to be traced in a good series of ex- amples. C. vectis appears to be the most uniform in size and structure. All the British species of this genus emit, when captured, a very offensive odour. Probably they can do this voluntarily ; if so, it may preserve them from the attacks of birds, or from molestation when in the act of oviposition in the nests of the industrious bees upon which they are parasitic. 2.

Wength 43 lines.—Black; the head and thorax punctured as in the other sex, the abdomen rather more strongly and evenly so; the face with a dense white pubescence, which becomes slightly yellowish towards the vertex. Thorax as in the other sex, with the calcaria as in the female ; the apical segment produced at the apex into two stout bifurcate processes ; the teeth acute, the lower teeth projecting beyond the upper ones, also a stout blunt tooth at the basal lateral margins of the segment ; all the segments with a fascia of white pubescence on the dorsal and ventral plates. B.M. This is a very local species. C. elongata is frequently mistaken for it; but the different-coloured calcaria, which are pale in C. sim- plea, will at once separate them, as well as the anal valves, which in C. quadridentata are quite different in form from the long acute ones of C. simplex. The insect described is certainly the Linnean species ; both sexes have been carefully compared with his types in the Museum of the Linnean Society, the figures of the ventral plates given in this work being drawn from them. 2.

B.M. I concur with Dr. Gerstaecker in considering this species to be the Cvelongata of St.-Fargeau. Why he altogether passes unnoticed the Kirbyan synonyma it is difficult to imagine, since that author has given ample and correct figures of all parts of the species, and, in addition, I have shown that, having examined the typical speci- mens, Kirby’s A. conica is decidedly this species, and also that his A. inermis is only a mutilated specimen of the male, the meta- thorax being split transversely and pushed upwards, thereby con- 144 APID®. cealing the teeth that arm the scutellum. In his description of the female will be found, ‘“ Tibie spinulis atris.” This is a mistake, the spines of the typical specimen being rufo-testaceous, which he states to be characteristic of his var. 3.mznor. Dr. Gerstaecker has questioned whether this is Nylander’s species ; but I have no doubt, as I possess that species from the author. C. mandibularis, I believe, is only founded upon specimens that have the mandibles partly opened, a circumstance that has been overlooked, and the geniculated appearance of the mandibles has been mistaken for a specific characteristic. (See Pl. IX. fig. 2 h.) This is the commonest species of the genus, and has been bred from nests of Megachile ligniseca, M. willughbiella, and M. cireum- cincta. Some small specimens were taken on the sandhills near Deal, where M. argentata abounds; it is probable that it is also parasitic on that species. 3.

(See Pl. IX. figs. 2%, 2u, 2n.) B.M. A pair of this local species were taken in Hampshire some years ago; they were recently disclosed, and their pubescence of a rich umber colour, which soon fades to the colouring described. The insect is parasitic on Saropoda bimaculata ; it has been subsequently found in abundance entering its burrows and on the flowers of the bramble in Sandown Bay, Isle of Wight, in the month of July. The apical segment of the female is like that of C. rufescens ; but the apex of the ventral plate is sharply oblique on each side, forming an angular ~ 6. c@LIoxys. 145 point ; the species is also uniformly considerably smaller and the abdomen much less convex. 4.

BM, This species is referred by Dr. Gerstaecker to the Anthophora co- noidea of Llliger, who in describing the species very briefly from a male insect, gives it as var. y. minor of Kirby’s Apis conica; this variety, on examining Kirby’s type, is found to be a male of C. elongata. It may possibly be the C. conoidea of Klug, described in Germar’s ‘ Reise nach Dalmatien;’ but its identification with Illi- ger’s imperfectly described species is impossible. Curtis’s name is therefore retained, his beautiful figure at once distinguishing it from all other species of the genus. This insect is the largest species of the genus found in Great Britain ; it is local, but has been taken plentifully in Sandown Bay, Isle of Wight, on flowers of the bramble; it is parasitic on Megachile maritima. Other localities known are Shirley Common, Wimbledon Common, Lowestoft, and Morthoe, North Devon. 7. OSMIA. 147 Subfam. IIIT. DASYGASTRA. Genus 7. OSMIA. Apis (pt.), Zinn. Syst. Nat. i. 953 (1766).

If I were asked which genus of bees would afford the most abun- dant and interesting materials for an essay on the diversity of in- stinct, I should without hesitation point ont the genus Osmia. Mr. Kirby, in the ‘ Monographia Apnm Anglie,’ has quoted the history of Réaumur’s mason-bee, which, although closely allied to the bees included in this genus, differs generically ; but its history is parallel to that of some of the European Osmice. It is merely alluded to here in order to direct attention to the highly interesting history given by Réaumur of its economy. Species of the genus Osmia are appa- rently confined in their geographical range to temperate climates. About sixty species are known, forty being found in Europe, eight or ten in North Africa, the rest inhabiting the United States, Nova Scotia, and Hudson’s Bay. ,The most abundant species found in this country is Osmia rufa ; its economy is varied by circumstances. In hilly country or at the seaside it frequently forms its burrows in the sunny side of cliffs or in sandy banks; whilst in cultivated districts, particularly if the soil be clayey, it selects a decaying tree, usually preferring the stump of an old willow ; at another time it burrows in the mortar of old walls. It occasionally avails itself of holes adapted to its requirements, such as the lock of some outhouse-door or a cayity in L2 148 APID A. flint stones used in the rock-work of a garden ; for in both situations I have found them. Its nest was once discovered in the tube of a fife that had been left on a shelf in a garden-arbour. This remark- able example of insect-economy is preserved in the collection of insect-architecture at the British Museum. The bee had constructed fourteen cells, a fifteenth being left unfinished; the insect had entered the fife at the lower end and commenced the first cell a quarter of an inch below the mouth-hole. In France this species has been bred from snail-shells by M. Bellevoye; in the shells of Helix nemoralis and also of H. hortensis the cocoons were placed in succession singly ; but in the shells of H. pomatia they were found in succession placed side by side, from two up to six, according to the width of the whorl. The Osmic lay up in each cell that they construct a store of food consisting of a mixture of pollen and honey, upon which the larva feeds. When it is full-grown the larva spins a tough darkish brown cocoon, in which it remains a few weeks, before it changes to the pupa state ; the majority soon arrive at their perfect condition; many, however, pass the winter in the larva state. In attempting to account for so remarkable a circumstance all must be conjecture ; but it is not of unfrequent occurrence. Osmia leucomelana, according to present observation, always excayates its burrows in the pith of dead branches of the common bramble: with little labour the parent bee removes the pith, usually to the length of from five to six inches; at the end she deposits the requisite quantity of food, which she closes in with a substance resembling masticated leaves, evidently vegetable matter: five or six of these cells are usually constructed in one bramble stick. The bee does not remove the whole of the pith, but alternately widens and con- tracts the diameter of the burrow, each contraction marking the end of a cell. The bee deposits an egg on the food immediately before closing up the cell; it is oblong, white, and about the size and shape of a caraway-seed. The larva is hatched usually in about eight days; it feeds about ten or twelve, when it becomes full- grown; it then encloses itself by spinning a thin silken covering, in which it remains in an inactive state until the following spring, when it undergoes its transformations, and usually appears in the perfect condition in the month of June. Osmia fulviventris burrows in posts, rails, or decaying trees, sel- dom in any other situation: the same habit will be observed in O. enea; but it is not constant, for I have observed this bee more than once constructing its burrow in the mortar of walls and also in bard sandbanks. 0. aurulenta and O. bicolor are bees that commonly burrow in banks, both being very abundant in some localities, forming colonies; but although it is undoubtedly the natural habit of these species to construct tunnels in hard banks with great labour and untiring perseverance, still we find them at times exhibiting an amount of sagacity and a degree of knowledge that at once dispels the idea of their actions being the result of a mere blind instinct, impelling them in one undeviating course. A moment’s consideration will suffice to call to mind many tunnels 7. OSMIA. 149 and tubes ready formed which would appear to be admirably adapted to the purposes of the bee; for instance, the straws of a thatch and many reeds ; and what could be more admirably adapted to their requirements than the tubes of many shells? So thinks the bee! O. rufa, O. aurulenta, and O. bicolor all select the shells of Helix hortensis, H. nemoralis, or of H. pomatia. ‘The shells of these snails often lie hidden beneath grass, mosses, and plants; the bees finding them in such situations, dispense with their accustomed labour and take possession of the deserted shells. The number of cells varies according to the length and diameter of the whorl of the shell selected, the usua] number being four; but in some instances they construct five or six ; and when the bee takes possession of the shell of H. pomatia, as I have already mentioned, the number is considerably increased. When the bee has completed and provisioned the cells, the whole is carefully protected by closing up the entrance or mouth of the shell with small pellets of clay, sticks, and pebbles; these are firmly cemented together with some glutinous matter, and the bee has finished her task. We will now observe the intelligence of the bee under different circumstances: she has selected the adult shell of Helix aspera; the whorl of this species is greater in diameter than that of H. nemo- ralis or of H. hortensis—too wide, in fact, for a single cell. Our little architect, never at a loss, readily adapts it to her purpose by forming two cells side by side; and as she advances towards the entrance of the whorl it becomes too wide even for this contrivance. Here let us admire the ingenuity of the little creature ; she constructs a couple of cells transversely! And this is the little animal which has been so blindly slandered as being a mere machine. I will take this opportunity of correcting a very widely diffused error, which appears to have originated with Réaumur ; or, if his account of the development of Xylocopa be correct, it differs from that of every wood-boring bee in this country. He says, ‘“* When the larva assumes the pupa it is placed in its cell with its head down- wards,—a very wise precaution ; for thus it is prevented, when it has attained to its perfect state and is eager to emerge into day, from making its way upwards and disturbing the tenants of the super- incumbent cells, who being of later date, each than its neighbour be- low stairs, are not yet quite ready to go into public.” Mr. Kirby also quotes from a letter by the Rev. George Ashby, who, after describing the nest of Megachile centuncularis, says, “The lowest and first born passes out through the bottom of its own (lowest) cell, and so escapes without disturbing the rest, who are not yet ready to emi- grate.” But all such conclusions originate, in my opinion, in con- jecture. In the case of bees constructing their cells in the spiral tube of a snail’s shell, where is the possibility of escape? And I have been informed that species of Xylocopa, in India, very commonly make use of bamboo-sticks used in making fences in which to con- struct their cells, and that no outlet can be found except at the entrance to the tube. Bees that form tunnels in sandbanks never have more than one outlet to their nests. When Chelostoma flort- 150 APIDZ, somnis avails itself of the tube of a straw or reed, how is the insect to pass the first knot, whick would oppose its escape? True know- ledge is to be found in the careful investigation of nature. A bee is observed to alight on-an upright post; she commences the formation of her tunnel, not by excavating downwards, as she would in that case be incommoded with the dust and rubbish which she removes; no, she works upwards, and so avoids such inconveni- ence. When she has proceeded to the length required she proceeds in a horizontal direction to the outside of the post; and now her operations are continued downwards ; she constructs a cell near the bottom of the tube, a second and a third, and so on to the required number. The larve when full-fed have their heads turned up- wards; the bees which arrive at their perfect condition are the males; and it is these that are first anxious to escape ; they usually do so several days before the females. This is the history of every wood-boring bee that I have bred; and I have reared broods of nearly every species indigenous to this country. There is another species of this genus, whose habits are so different from the rest that our admiration of the ingenuity of these bees is greatly increased when we consider its curious details and retlect upon the degree of care and foresight exhibited by the provident parent; this is the Osmia parietina, a bee only as yet found in the northern parts of this country. This species selects the underside of a slate or stone lying on the ground and having a hollow space beneath ; to the underside of such stone the bee attaches little masses of pollen and honey ; on each she deposits an egg, from which a larva is hatched in a few days, which feeds upon the provision stored for it by its provident parent. A stone of this kind was found in 1849 at Glen Almond, Perthshire, on the Grampians, at an eleva- tion of 800 feet above the level of the sea, by Mr. J. Robertson, who, on turning up the stone, observed a mass of cocoons of some insect. Although not possessing much knowledge of entomology, still he knew them to be the production of some insect; he pre- sented the stone to the British Museum, and it was placed in my hands for observation. The size of the slab was 10 inches by 6, and the number of cocoons attached to it 230: when first dis- covered, about one third of them were empty ; this was in the month of November. In the beginning of the following March (1850) a few males made their appearance, and shortly afterwards a few females were developed ; they continued to come forth at intervals until the end of June; at this time there remained thirty-five unde- veloped cocoons. On opening one or two in 1851 they proved to contain living larva. These cocoons were again carefully closed and the whole left undisturbed until the month of April of the fol- lowing year (1852), when, on examination, they were found still to contain living larve. At the end of May these changed to pupa, which about the end of June became perfect insects, when both sexes made their appearance. This, then, was the result: a portion of eggs deposited in 1849 had been three years arriving at maturity; ov rather in all probability their development bad been retarded ; a a 7. OSMIA. 151 when discovered in 1849 one third of the cocoons were found to be empty ; in 1850 a few males and females appeared; in 1851 the same occurrence took place, and then the stone was presented to the British Museum and placed in my hand for observation ; in April 1852 all the rest of the cocoons produced bees or parasites, the latter proving to be a species of ruby-tailed fly, Chrysis bicolor, a species new to the British list. In the first instance all the de- posit was subjected to the same influences and had produced larve ; the same may be said of them when taken by Mr. Robertson to Edinburgh, and yet only a few of each sex were developed. The fol- lowing year produced the same result ; and the third year the rest appeared. What was the cause of this retarded development it is difficult to conceive. Osmia xanthomelana belengs to the division of mason-bees ; its nest is usually constructed at the roots of grass, but occasionally in a hollow chamber about an inch underground. The cells are pitcher-shaped, and constructed of mud mixed with small pebbles; outside they are very rough, but the inner surface is perfectly smooth, the whole reminding one of the texture of a swallow’s nest. The cells are each about 5 lines in length, rounded at the bottom, but flattened at the top and closed by a lid, which the bee con- structs after having provisioned the cell; the cells are placed close side by side and are more or less joined together; a nest when com- pleted usually contains five or six cells. This species appears in May or the beginning of June ; its brood undergoes its transformations and attains the perfect condition by the end of August or the beginning of the following month; in this state it passes the winter months ; but occasionally a few remain throvgh the winter in the larval con- dition. There are several parasites on the different species of Osmia be- sides the bee parasites of the genus Stelis: Chrysis ignita is a com- mon destroyer of the larvae of O. rufa, and C. fulqgia has been bred from the cocoons of the same bee; but its most destructive parasite is a chalcididous insect, WMonodontomerus dentipes ; large numbers of this insect have been obtained from their nests. Chrysis ignita has been reared from the cocoons of Osmia xanthomelana ; and it would no doubt attack the nest of any species of bee that it found adapted to its purpose; bee or wasp suits it equally well. I have obtained it in plenty from a nest of Vespa rufa, also from nests of Odynerus antilope ; their larvee appear to be almost omnivorous. Osmia papaveris (the Anthocopa of St.-Fargeau) is not included in this genus, there not being any reliable evidence of its having been © found in this country, Shuckard has included O. papaveris in his work ‘ British Bees,’ on the authority of specimens placed in the collection of British Aculeata in the British Museum. There are threé specimens of the female, and two males of Osmia adunca arranged with them as being those of O. papaveris: these are all without locality ; but they have small tickets bearing numbers that exactly correspond with others attached to species never found in this country. There can be little doubt of the specimens of the 152 APIDZE. two species of Osmia named, as well as others of O. cornuta also placed in the collection, having been introduced by mistake subse- quent to Dr. Leach’s death, who left his boxes of continental and British Aculeata mixed, to be separated and arranged by others. The habit of cutting sections of the petals of flowers for the purpose of lining their nests is not confined to the Osmia papaveris, which, from using for that purpose the petals of the scarlet poppy, has in consequence acquired the popular name of the poppy-bee. Megachile centuncularis I have seen cutting the petals of scarlet geraniums, and also Megachile argentata lining her nest with the bright yellow petals of Lotus corniculatus. Section I.

One of the most abundant bees found in England, forming occa- sionally large colonies. Osmia cornuta is given in old lists of British bees as being an indigenous species ; but no sufficient or reliable evi- dence of its being so exists. Specimens are placed in the British collection of bees in the British Museum, but they have no locality attached to them; the species is therefore omitted in this work. 2. Osmia enea.

B.M. This is one of the most abundant and widely distributed species of the genus. Its usual time of appearance is June. Its habit is varied: at one time it selects holes in walls; but I have most fre- quently bred it from old posts &c. The name adopted is that of the male. It will be seen that Linnzeus described both sexes on the same page; and the generally recognized rule of adopting the male appellation, in my opinion, should be rigidly adhered to; but in a few exceptional cases a departure from the general rule will be fully justified. 3.

BM. This species is not rare, but rather local. It usually appears in June, females being found as late as August. It is frequently found on thistle-heads, also on hawkweed; it burrows in wood. WStelis pheoptera may occasionally be taken about its burrows. It is widely distributed, specimens having been received from Scotland and from most parts between that locality and Cornwall. Mr. Vernon Wol- laston found it in Madeira. Section II. Body black. (Sp. £-11.) 4. Osmia xanthomelana.

B.M. This is a very local species. It appears about the end of April or the beginning of May. Mr. Kirby discovered it at Somersham, neat Ipswich. It has been found subsequently at Darenth Wood ; and near Liverpool Mr. George Waterhouse took it in abundance, finding its nests and breeding the sexes. He has published an in- teresting account of its economy in the second volume of the ‘ Zoolo- gist.’ Near Bristol it has been observed frequenting the ground-ivy (Glechoma hederacea) ; other localities known are Eastbourne and the neighbourhood of Exeter. ‘The male placed by Mr. Kirby in his col- lection as belonging to this species is that of Osmia fulviventris. 5.

BM. The insect described was named 0. fuciformis by Dr. Nylander, but was regarded by myself as a variety of O. wanthomelana in the first edition of this work. Dr. Gerstaecker has pointed out a character which appears to separate this from O. wanthomelana, namely the opaque space at the metathorax of one, and the shining space in the other. Dr. Gerstaecker, however, I believe, has applied these distinctive characters to the wrong insects. Kirby’s type of O. aan- thomeluna has the base of the metathorax shining; in my O. fuc?- formis it is opaque, and the species is smaller than the former insect. The basal joint of the posterior tarsi 1s covered within with jet-black hairs ; in the other species they are more or less rufous. I do not know the male. The character “ metatarso postico apicem versus sensim dilatato,” which Gerstaecker assigns to his O. fuciformis, is precisely that of the male of O, wanthomelana. Taken at Birch Wood, Kent. 6.

Abdomen subglobose, shining, and with fine shallow punctures ; the basal segment with thin, pale fulyous pukescence, on the rest of the segments it is 158 APID A. black ; the apical margin of the sixth segment entire, the seventh with a small notch in the middle. B.M This insect isnot found in the west of England. Mr. Curtis took it some years ago in the month of June at Ambleside, Westmoreland. In describing the species he has stated that the colour is obscure in certain lights. It might have had an eneous reflection, particularly if an old specimen was examined. I had many opportunities of ex- amining his bees; and they were certainly the same species as mine from Scotland. Mr. Curtis so named them himself; and I gave him both sexes. The colour of the abdomen of the female is black, occa- sionally reflecting an obscure neous tint. Dr. Gerstaecker thinks my O. parietina distinct from that described by Mr. Curtis. This is a mistake: the insects have been most carefully compared, and Curtis agreed with me in considering them identical. The only other localities known are Bridgend (Glamorganshire), Loch Rannoch (Perthshire), and the Grampian Hills. 7. Osmia pilicornis.

The female of this species has a close general resemblance to the same sex of O. parietina, from which it is distinguished by having fulyous pubescence on the two basal segments of the abdomen and black pubescence on the face ; its smaller size will separate it from O. xanthomelana ; and it has the legs with entirely black pubescence. This species was first discovered by Capt. Blomer, subsequently by Dr. Thwaites, on Durdham Downs, who proposed the specific name O. pilicornis, It has also been found in Leigh Woods, near Bristol, in some abundance, and also at Birch Wood. It appears about the end of May, but is a very local insect. 8. Osmia aurulenta. O. nigra, ferrugineo-rufo villosa, abdominis segmentis marginibus fulvis, ano in mare bidentato.

B.M. This is a very common species in the western and south-western counties, but has not been received from the north; it usually appears about the end of April, but has been taken in March. It has been observed to be most abundant in chalky districts, where it is common on the Letus corniculatus. Very fine and richly coloured specimens have been taken in North Wales, at Llanberis. In the neighbourhood of Bristol this bee very commonly constructs its cells in snail-shells. 9. Osmia bicolor.

It usually ap- pears in April, when it has been taken plentifully at Purfleet and in chalk-pits at Northfleet. Near Bristol it very commonly constructs its cells in snail-shells, from which I have freyuently bred it. The pubescence of the male soon fades to cinereous or nearly white. The description is that of a bred specimen. 10. Osmia leucomelana.

B.M. This is a rare or very local species which appears in June, I once found it at Charlton, near Blackheath. At Hawley, near Blackwater, Hants, | found it burrowing in dead bramble-sticks, from which both sexes were bred. It has also been taken at Weybridge early M 162 APID 2. in July, and in Leigh Woods, near Bristol, at the end of May. Mr. Kirby took it at Coddenham, near Needham Market, Suffolk, but only the female. In his Monograph he has described the apical spines of the tibie as being black; this is an oversight: his own typical specimen has them rufo-testaceous. This circumstance has, I believe, caused both Schenck and Thomson to mistake his species, who accurately describe the sexes of O. leucomelana under another name. 11. Osmia spinulosa.

It is not uncommon at Luccomb Chine, Isle of Wight, and has been taken at Croydon and Reigate ; it frequents the hawkweed, wild scabious, and the thistle. The pubescence is frequently almost entirely cinereous above. The specimens described are in fine condition. 8. HERIADES. 163 Genus 8. HERIADES. Apis (pt.), Linn. Syst. Nat. i, 954 (1766).

B.M. Heriades truncorum is a very rare species in this country, but less so on the continent: I have received it from Westphalia in some numbers. Mr. Kirby received it from his friend Mr. Trimmer, who took it near Brentford, where I have searched for it unsuccessfully. Mr. Ingall found it near Dulwich, taking three or four specimens. It must no doubt be looked for about old posts and rails in June. It is a species I never met with. Genus 9. CHELOSTOMA. Apis (pt.), Linn. Syst. Nat. i. 954 (1766). Hyleus (pt.), Fabr. Syst.

Head subquadrate, rather wider than the thorax ; ocelli in a tri- angle; antenne subclavate, short, a little longer than the head, slender and filiform in the male, with the intermediate joints den- ticulate beneath; labrum elongate, narrowed anteriorly, and trun- cate at the apex ; mandibles bidentate, ciliated on their inner mar- gin; the labial palpi 4-jointed, the basal joint one third the length of the second, the second joint attenuated at the apex, the third short and placed in a line with the second; the fourth clavate and arti- culated to the side and near the apexofthe third. Maxillary palpi 3-jointed, the joints short and subequal. Anterior wings with two submarginal cells, the second receiving both the recurrent nervures. Abdomen as long as the head and thorax, subclavate, and with a dense pollen-brush beneath; in the male the abdomen cylindrical, incurved, the apex armed with two blunt teeth ; beneath, the second segment produced into a large concave mucro, the fourth segment being densely pilose. This genus and Heriades are very closely allied: both have 3- jointed maxillary palpi, and 4-jointed labial ; but in Chelostoma three joints of the labial palpi are articulated in a line, the fourth being attached to the side of the third ; in Heriades only two are in a line, the third and fourth being minute and attached to the second; the neuration of the wings is the same in both genera. Both the British species burrow in decaying posts and rails; but, like many species of burrowing-bees, they occasionally make use of ready-formed burrows. Not unfrequently Chelostoma florisomne makes use of straws and reeds, their tubes being admirably adapted 9, CHELOSTOMA. 165 to the bees’ requirements: on one occasion | found numbers occu- pying the straws of a thatched outhouse. Chelostoma is subject to the attacks of several parasitic insects; Chrysis cyanea and C. ignita have both been bred from its nests, also Fwnus assectator, an insect frequently seen where the burrows of Chelostoma are found. Mr. Marsham, in the ‘ Transactions of the Linnean Society,’ volume iii., has given an account of Pimpla manifestator introducing its eggs into the nests of this bee; but it is not very clearly shown that the larva of Chelostoma was the object of its attack. I am inclined to suspect it was the larva either of Melandrya caraboides or that of Clytus arietis ; both these insects are commonly to be seen about the burrows of Chelostoma, inserting the apical segment of their ab- domen into them, the burrows forming a suitable situation for their eggs, and the larve being wood-eaters. Mr. Kirby records the fact of his friend Mr. Trimmer obtaining Jchneumon femorator from the nest of Chelostoma. The males of this genus usually pass the night in flowers, in which they curl up their bodies and take their repose; but at other times they pass the night in a position that would appear to be ill suited for repose. I have observed them attaching themselves to blades of grass by seizing hold with their mandibles and suspending them- selves in a horizontal position, with their hind legs stretched out in a line with their bodies. A number of males thus suspended were found on a dead branch of hawthorn; they were killed by chloro- form, and remained thus attached after death, so that the branch and bees could be exhibited at a meeting of the Entomological Society of London, Other species of Hymenoptera (for instance, some Polistidze) attach themselves in asimilar manner. Other insects curl their bodies round straws, twigs, or blades of grass: this is the habit of several species of Chrysidide, of StiJbum and Hedychrum, and of Elampus panzeri. 1.

This is a very common insect in this country, appearing early in June; itis found throughout Europe, and is one of the true carpenter bees. A closely allied species, C. nigricorne, which occurs in Den- mark, Sweden, and France, will probably be found in North Britain, and may be mixed with C. floriscmne in collections. The male of C. nigricorne has the antenne entirely black and the joints simple ; the apical segment deeply concave, its margin truncate, the lateral angles being subdentate or acute; the female wants the tubercle on the clypeus. This short description will serve to identify the species. 2. Chelostoma campanularum. C. atrum, glabriusculum ; maris ano inflexo, acute bidentato, ventris basi gibba.

Head nearly as wide as the thorax; ocelli in a triangle on the vertex ; antennee filiform, the scape subclavate, the basal joint of the flagellum subglobose ; clypeus triangular, truncate at the base, rounded anteriorly ( 2 ), truncate ( ¢ ) ; tongue elongate, nearly thrice the length of the mentum ; paraglossw very short; labial palpi 4- jointed, the first and second joints elongate, the second longest and tapering to a point, near its apex the third and fourth minute joints articulate, both being subclavate ; mavillary palpi 2-jointed, the basal joint short and cup-shaped. Thorax subglobose ; the scute/lwm trans- verse and lunate, produced over the metathorax, which is truncate ; anterior wings with one marginal cell, which is as long as the two submarginal ones united ; the second submarginal cell receiving the first recurrent neryure near its commencement, the second sometimes uniting with the apical nervure, and in some instances passing a little beyond it; the basal joint of the anterior and intermediate tarsi as long as the tibie; the claws bifid. Abdomen convex, in- curved, the base truncate; densely clothed with long hair beneath. Male much larger than the female, the legs more elongate, and the apex of ‘he abdomen armed with spines. 168 APIDE. This genus is remarkable in presenting the only instance among our native species of bees in which the male is considerably larger than the female; this peculiarity is at once understood, and the object of the structural difference apparent, when the habits of the insect are observed. ‘The female is usually attended by the male, and when on the wing, flying from flower to flower, is frequently seized by the male, and carried off out of sight into the air; hence the necessity for his superiority in size and strength is clearly apparent. In this country only a single species is found; but upwards of a hundred are described, about forty inhabiting Europe alone. Many species are found in Arabia and Syria; others are found in Algeria, the Gambia, Sierra Leone, the Cape of Good Hope, Natal, and Angola ; four or five are known from India; and others from Brazil and various parts of South America, Chili, Mexico, and the United States. Anthidium manizatum has never been observed constructing its own nidus; and probably it at all times makes use of some cavity in trees, posts, or other situation adapted to its requirements ; its nests are frequently found in the holes perforated in old willow-trees by the larvee of Aromia moschatus or Cossus liguiperda, and lined with a woolly down, which the bee collects from various plants, such as the hedge-nettle, Stachys germanica, and the wild lychnis, Agro- stemma coronaria ; from such plants the bee with its broad man- dibles scrapes off the downy covering of the leaves and stems, rolling it up into a little bundle which she carries off to her nidus. The cells are not arranged in the systematic order usually observable in bee architecture ; they are composed of a thin semitransparent mem- brane, each cell being closed with similar membrane after being stored with a suitable supply of pollen and honey, upon which an egg has been deposited ; in this manner cell after cell is constructed, until the cavity chosen is filled with a suitable number, when her labours are completed. Nests of a species of Anthidium from Natal are attached to the outside of twigs of bushes or plants, each cell being enveloped in a woolly covering and separate from each other. The Rey. Gilbert White, in his ‘ History of Selborne, with his usual tact, has described the habit of our British species thus :— ‘«‘ There is a sort of wild bee frequenting the garden campion for the sake of its tomentum, which probably it turns to some purpose in the business of nidification. It is very pleasant to see with what address it strips off the pubes, running from the top to the bottom of a branch, and shaving it bare with the dexterity of a hoop-shaver. When it has got a vast bundle, almost as large as itself, it flies away, holding it secure between its chin and fore legs.” 1. Anthidium manicatum.

Abdomen variable in its markings, having a lateral ovate 170 APIDE, spot on the four basal segments, a minute one on the fifth, and two central transverse marks on the fifth and sixth ; the sixth with a lateral stout bent acute tooth, the seventh has an obtuse one on each side and a minute slender one in the middle; the base with a thin cinereous pubescence, and at its extreme lateral mar- gins a tuft of silvery pubescence ; the following segments have a pale fulvous fringe. B.M. Var. 3. The seventh segment has sometimes two large transyerse spots, those on the sixth being obsolete. Var. y. The apical transverse spot obsolete. This species varies greatly in the presence or absence of the yellow spots and stripes on the abdomen and legs. Var. @ was in the col- lection of Mr. Desvignes, who obtained it from Scotland. It is of great rarity in this country, but very common on the continent. Dr. Sichel sent examples of the ten varieties described by Latreille in his Monograph of the genus in the Ann. du Mus. d’Hist. Nat. vol. Xili., several of which have not been found in Great Britain. The variety (3 of the female, so common in France, is rare in this country, and our common form of colouring rare on the continent. This bee usually appears at the end of June or beginning of July, and is abundant in all parts of the south of England, but appears to be much less so in the north. It is very partial to the flowers of the red archangel, Lamium purpureum, and sometimes swarms where that plant i is plentiful. ‘Genus 11. MEGACHILE. Apis (pt.), Linn. Syst. Nat. 955 (1766).

Meyachile is the most cosmopolitan of all the genera of bees. 11. MEGACHILE. Well The number of known species is about 300; they are numerous alike in the tropics and in northern latitudes. The type of the genus is perhaps the most widely distributed species of the Apidee, being found in Southern Europe, Russia, Denmark, Sweden, Finland, and Lapland, also in Canada and at Hudson’s Bay. Fifty species are known from India, China, and the various islands in the eastern archipelago, forty from Australia ; but no species has been received from New Zealand. Africa has furnished between forty and fifty species ; and others may be yet found in Madagascar, the Mauritius, and other adjacent islands. South America has at present yielded between fifty and sixty species; and about the same number have come from Mexico and the States of North America,— thus making the present known number of species, as already stated, about 300 ; and many are yet doubtless unknown to science. The habits of the British, and, indeed, of all the known European species appear to be uniform in one respect: they all excavate bur- rows, either in the ground or in wood ; and these they line either with the cuttings of leaves or of the petals of flowers. Some of the exotic species have a different habit. Megachile lanata, a common Indian insect, constructs tubes of agglutinated particles of sand; the same is also the habit of another Indian species, M/. prowima. Megachile centuncularis burrows usually in wood; frequently, however, it does so in the ground ; and I have seen it entering holes in the mortar of walls. These it lines with cuttings of the leaves of different trees and plants, making use of those of the rose, the laburnum, the lilac, and of various kinds of sallows ; but on two oc- casions I observed it cutting the petals of the scarlet geranium, pro- bably for the purpose of lining the cells. I am inclined to think so, because I frequently found the cells of Megachile argentata, which burrows in the ground, lined with the yellow petals of Lotus corni- culatus. The outer covering of the cells of this little bee is usually cuttings of rose-leaves ; and the circular pieces used for closing the cell I have found to be those of the thick leaves of the buckthorn. The plants it prefers frequenting appear to be Erhium vulgare and the hare’s-foot trefoil, Trifolium arvense. Ihave frequently observed Mutilla ephippium entering the burrows of this bee, but have not succeeded in rearing it from the nests. Megachile willughbiella is the most common of the British species. It is widely distributed, and very abundant in most parts of the country. In Kirby’s ‘ Monographia’ is givenan extract from Sir John Hill’s translation of Swammerdam’s ‘ Book of Nature.’ In a note, Sir John says that he saw thousands of the nests of this species in Lincolnshire in willow trees. In the British Museum is preserved a piece of a willow tree in which are numerous burrows of this bee ; some of them are exposed, and in one are no less than thirteen cells. In one case one common entrance leads to three burrows. ‘The flat end of the block is about 24 inches square ; and in this space are no less than ten burrows. Megachile maritima usually burrows in the ground. I have not observed it in any other situation. Its nests are found in the cliffs 172 APIDE. of Sandown Bay in great numbers ; but I have not found it burrow- ing in wood. This bee is frequently seen on the flowers of the mallow, Malva sylvestris ; and where that plant is not found it ap- pears to choose the common bramble. Megachile circumeincta is a ground-burrower, and sometimes forms colonies of considerable extent. M/. ligniseca is, as I believe, exclu- sively a wood-burrowing species, preferring trees that are more or less in a decaying state; the elm, oak, or ash appear equally to answer its purposes, Div. I.

Abdomen oblong-ovate, the margins of the segments deeply depressed ; at the base there is a little cinereous pubescence, towards the apex it is sparing and black; beneath densely clothed with fulvous pubescence, that on the two apical segments is black. BM. Male. Length 5-6 lines.—The face clothed with bright pale yellow pubescence ; at the insertion of the antenne it is of a deeper yellow, and on the vertex black; the antenne filiform, half the length of 174 APID®, the thorax, which has a yellowish brown pubescence on the disk, on the sides and beneath it is cinereous; the wings and legs as in the other sex; the anterior coxe unarmed. The abdomen oblong- ovate, the two basal segments have a thin pale pubescence, the margins depressed ; the intermediate ones have on each side a short pale fringe; the apex inflexed, the margin of the sixth segment emarginate, BM, This species appears to be rather local; it is found round London, but only occasionally. Mr. Kirby found its nests in old elm trees, its burrows being lined with the leaves of that tree. I have observed it most commonly at Richmond, Hampton Court, and Windsor. In some districts it is doubtless plentiful. Owliorys simplex was bred from its burrows at Dartford, Kent. 3. Megachile versicolor.

Length 47-53 lines.—Black ; the head and thorax closely and rather strongly punctured. The mandibles with four acute teeth ; the face with dense pale fulvous pubescence on each side ; the clypeus coarsely punctured. Thorax, the pubescence on the sides pale fulvous ; beneath and on the legs above it is more or less cinereous ; the three apical joints of the tarsi ferruginous; all the tarsi with rufo-fulvous pubescence beneath. Abdomen shining; on the apical margin of the segments laterally a narrow fringe of white pubescence ; beneath, the pubescence is rufo-fulvous on the second, third, and fourth segments, and black on the fifth and sixth. B.M. This species is most like M. centuncularis. All that I have seen (about a dozen examples) agree in the particular distinctions pointed out—the moreacute mandibles, and the bicoloured pubescence beneath the abdomen. The specimen from which the description is drawn is one in very fine condition ; others have the pubescence on the sides of the thorax more or less grey. I am not certain about the deter- mination of the male, but have a specimen that differs from the male of M. centuncularis in having the margin of the seventh seg- ment laterally dentate, and in the middle of the segment a prominent larger tooth. This may prove to be the true male. The female has been taken at Weybridge, Bournemouth, Bristol, and Carlisle. 4. Megachile pyrina.

The specimen in the British Museum is the only one I have seen ; but Dours includes the species in his ‘ Catalogue des Hyménoptéres de France.’ The British specimen is from Dr. Leach’s collection, and has a numbered ticket attached. On reference to his private manu- script catalogue the entry is found:—“ June: found settling on a footpath near our house ” at Spitchwick, Devonshire. 176 APIDA. 6. Megachile argentata.

Abdomen short and obtuse at the apex, towards which it is somewhat narrowed ; all the segments with narrow pale marginal fascie, the apical segment clothed with it and having its margin denticulate ; the margin of the seventh segment entire. This little bee is local, but in some situations abundant, particu- larly so on the sandhills at Deal, at Littlehampton, and in Whitc- sand Bay, at the Land’s End. It also occurs at Southend, Wey- bridge, and at Burnham, Somerset. Its flight is as rapid as that of Saropoda bimaculata, and it also makes a similar piping hum. It is found in June, July, and August, and often frequents Evhiwm vulgare, and is also partial to the hare’s-foot trefoil. The specimens described are in the finest condition, taken on their first appearance. They are frequently found entirely bleached to a hoary pubescence, and are usually found with the fulvous tinge more or less faded. This species is sometimes mistaken for the poppy- bee, Osmia papaveris, 11. MEGACHILE. WaT Diy. Il. Anterior tarsi of the males dilated. 7. Megachile circumcincta.

BM. This species appears in June; it is rather local, and, as far as has been ascertained, always constructs its burrow in the ground. Oc- casionally | have met with large colonies, especially in Surrey and Hampshire. This bee usually lines its burrows with cuttings of rose- leaves; St.-Fargeau says he observed it using those of Rhamnus frangula (the alder buckthorn): all the species vary in their choice in this respect.

Head transverse; ocelli in a triangle on the vertex ; antenne short and subclavate ; mandibles stout and tridentate ; Jabial palpi 4-jointed, the two basal joints elongate, the third and fourth minute, arti- culated near the apex of the second joint; the mawxillary palpi 6- jointed, the three basal joints about equal in length, the three apical ones minute, each gradually decreasing in length. Thorax ovate; the anterior wings with three submarginal cells, the second forming a truncated triangle, the second and third cells each receiving a re- current nervure a little beyond the middle. Abdomen subclavate, convex, with the two basal segments constricted. This genus of bees is widely distributed ; at present about forty species are known; six are European, four African, and sixteen Asiatic. Of New-World species fourteen are known; it has not as yet been found in Australia, but a closely allied genus, 7’haumatosoma, appears te take its placein West Australia. The genus Ceratina was formerly classed among the parasitic bees; St.-Fargeau considered them to be parasitic from the circumstance of their being destitute of the usual pollinigerous appendages. Spinola was the first to cor- rect this error in a memoir in the Annales du Muséum d’Hist. Nat. 1807, where a correct history of their economy is given. I have observed them making their tunnels in dead bramble-sticks. Two species are described as British; the second, C. cucurbitina, is be- lieved to have been found in South Devonshire many years ago ; it requires confirmation by subsequent capture to establish the species as really belonging to our fauna. 1.

Thorax, the mesothorax with a cen- tral impressed line and also a short one opposite each tegula; the wings fusco-hyaline and iridescent; the pubescence on the legs cinereous, but on the posterior tarsi beneath it is yellowish; the apical joints of the tarsi rufo-testaceous, the calcaria pale testaceous. Abdomen, the sixth segment with a central carina terminating in a sharp point at the apex ; beneath, the segments have a thin, long, pale pubescence. Var. 3. A minute pale spot on the clypeus. Male.—Usually about the size of the female, differing in having the elypeus and labrum white; the sixth segment of the abdomen as in the other sex, the seventh produced into an elevated mucro, which is deeply emarginate at the apex and rendered bidentate. B.M. This species was considered by myself and others to be identical with the Apis cerulea of Villars until Dr. Gerstaecker pointed out the error ; on referring to Villars’s ‘ Linnzei Entomologia,’ and comparing the description and figure with the British species, it is apparent that he describes a different species, which, I think, is identical with the Ceratina enca of Brulle. ‘eratina cyanea is a very local insect, but plentiful in certain lo- ealities. I have found it during June and July plentiful in the war- ren at Folkestone, frequenting the flowers of Echium vulgare; later in the season, in October, a quantity of perforated bramble-sticks were obtained from the same locality, and on examining them some weeks afterwards it was ascertained that they contained the perfect bee. By placing the sticks in a warm situation several came forth on Christmas day ; this clearly established the fact of the insect hibernating in the perfect condition. The species is not uncommon in the neighbourhood of Bristol, and has been taken sparingly at Charlton, Kent, at Birch and Darent Woods, at Weybridge and Budleigh-Salterton, South Devon. & 2.

Male. —Usually rather smaller than the female, and differing in having the clypeus entirely and a spot on the labrum white. B.M. The spots described as white are usually yellowish in cabinet specimens ; but white in fresh ones. I have considerable doubt of this being a British species. There is a single specimen, a male, in the Museum collection; it has a number attached; and in Dr. Leach’s MS. Catalogue the entry to the corresponding number is, “ Taken in Tothill Lane, Devonshire.” Ifthe entry really alludes to the Ceratina, no doubt future captures will prove the species to be indigenous. It is generally distributed on the Continent. Subfam. IV. SCOPULIPEDES, Latr. Genus 13. EUCERA. Apis (pt.), Linn. Syst. Nat. 1. 953 (1766). Eucera, Scop. Ann. Hist. Nat. iv. 8 (1869).

EUCERA. 183 Only one species of this genus is found in this country; but about twenty are described as inhabiting Europe; species have been found in Algeria; and one has been received from North China. St.-Fargeau mentions one from Cayenne. All the Brazilian species, the males of which have elongate antennz and closely resemble the genus Hucera, belong either to the genus Zetralonia or Melis- sodes, in both of which the anterior wings have three submarginal cells. Klug has described two species from Syria, and Spinola two from Egypt. Kirby describes four species belonging to his subdivision of long- horned bees ; his second species, which he names “ linguaria,” is a small faded form of Kucera longicornis; the third, “ pollinaris,” is a female belonging to the genus TZ'tralonia of Spinola, and is from the Cape of Good Hope; the fourth is a species of Melissocdes ; it is ina faded and bad condition, but is probably identical with Melissodes denticulata, described by myself in the Catalogue of Hyme- nopterous Insects, part 11. p. 311, and is from North America. Eucera longicornis appears usually in May, and prefers a stiff clayey soil in which to form its burrows ; they are sometimes found in large colo- nies, when numbers of males may be seen on the wing gyrating in all directions over the ground perforated with their burrows: occa- sionally they may be observed to come into contact, when two, three, or four will cling to each other, and get their long antenne _so intertwined that they have some difficulty in disengaging them- selves. Their burrows are usually about 6 inches in length: at the end of each an oval chamber is excavated; it is perfectly smooth within and coated or lined with a liquid secretion by the parent bee, which prevents the mixture of pollen and honey depo- sited in a semifluid state from being absorbed. Lach cell is the abode of a single larva, which passes the winter months in that con- dition ; about the month of April the change to the pupa state takes place ; and very shortly afterwards the perfect condition is attained. The pupa is enveloped in a thin transparent pellicle which encloses every limb. On arriving at the mature active state the bee by degrees frees itself from the shroud in which it was enclosed, and comes forth into the open air and sunshine. Immediately on emerging, it passes its antenne through the notch at the base of the first joint of the anterior tarsus, and thus divests those organs of the thin pellicle in which they were enclosed. The long antenne of the males of this and the two allied genera are doubtless adapted to some peculiar phase in the economy of these bees; and the remarkable hexagonal reticulation which covers their antenne is no doubt an adaptation which is connected with their peculiar function, but which we areas yet unable satisfactorily to appreciate. 1.

Male. Length 5-7 lines.—Black ; the labrum and clypeus yellow, the pubescence on the face yellowish white ; on the margin of the vertex, disk of the thorax, and two basal segments of the abdo- men it is fulvous; the antenne as long as the entire insect; the extreme apex of the abdomen fulvous; the wings and legs as in the other sex. BM. This species appears about the middle of May, and is generally distributed in this country, and widely so on the Continent, being found in France, Switzerland, Germany, Italy, Denmark, Sweden, Lapland, Russia, and Siberia. A colony of great extent was found about a mile beyond Southend, in a sloping bank at the foot of which, in the month of October, several years in succession, many specimens of Meloé rugosus were found; and although the beetle was never traced to the nidus of ELucera, it is very probable that it was parasitic upon it, no other bee except a species of An- drena having been observed burrowing in the same situation. Nomada seafasciata is the parasite of this species. | 14. saARoPopa. 185 Genus 14. SAROPODA. Apis (pt.), Panz. Faun. Germ. fase. 55. 17 (1800). Anthophora (pt.), Spin. Ins. Lig. i. 127 (1806).

Head transverse ; ocelli placed in a triangle on the vertex ; an- tenne filiform ; the labrum subquadrate, the anterior angles rounded ; mandibles bidentate, the teeth obtuse; tongue elongate, one third longer than the palpi; labial palpi 4-jointed, the first joint more than six times the length of the second, the two apical joints minute, the four joints consecutive; mawillary palpi 4-jointed, the basal joint short and robust and about one third of the length of the second, which is as long as the third and fourth joints united, the apical joint cylindrical. Thorax globose; the anterior wings with three submarginal cells, the second forming a truncated triangle and receiving the first recurrent nervure near the middle ; the third rounded at apical margin and receiving the second recurrent ner- vure at its extremity ; the claws of the tarsi bifid and rather large. Abdomen subovate, truncate at the base; the terminal segment with a smooth triangular plate which has rigid sete at its sides. The genus Saropoda contains at present a small number of species, . only nine being described: one is found in this country, one in Russia, four in Egypt, two in Africa, and one in Australia. From the latter countries additional species will probably come. This genus and Anthophora are very closely allied, and can only be separated by an examination of the tongue, the latter genus having 6-jointed maxillary palpi. Of all the busy bees that revel in the beauty of a summer’s day, Saropoda bimaculata must ever be an especial favourite ; it is only to be found when it is sunniest, brightest, and hottest—when sum- mer days are summer days indeed. Who has not heard its merry hum? Who has not seen it when for a moment it settles on a flower, or rests on some sunny bank, panting with delight ? the eyes splendid as opals; could their brilliancy be preserved, this bee would rival and challenge admiration with the most brilliant of its tribe. Itis a local species, but abounds in many localities. It flies with ineredi- ble swiftness, darting from flower to flower with the rapidity of lightning ; again settling it resumes its loud and cheerful note, merry and joyous as the cricket on the hearth. Saropoda bimaculata burrows in banks and sandy cliffs. Large colonies are found occasionally; at Sidmouth, in South Devon, and particularly at the top of the cliff at High Peak, a mile from the town, its numbers are incredible. It is found at intervals along the line of cliff all the way between this and Budleigh-Salterton, a distance of about eight miles; it is also extremely abundant in Sandown Bay, Isle of Wight, where the cliffs are riddled with its burrows; still it is a local insect, not found very near to the 186 APIDZ. metropolis. It formerly occurred at Coombe Wood, and is not un- common at Weybridge and at Blackwater, Hants. 1. Saropoda bimaculata.

This bee, usually appearing in July, is frequently found on the purple heath, and no doubt frequents other flowers ; but I have not frequently observed it doing so. Kirby’s A. rotwndata is this species in finer condition than his A. bimaculata. The descriptions of the 15, ANTHOPHORA. 187 sexes are those of the insect in perfect unbleached condition ; these bees, appearing only in hot bright sunny weather, soon fade and become more or less cinereous.

Head transverse, not quite as wide as the thorax; ocell: in an isosceles triangle on the vertex; antenne short, subclavate, the scape shorter than the second joint of the flagellum; the labrum subqua- drate, its anterior margin more or less rounded ; the clypeus convex and produced ; tongue elongate, one third longer than the palpi; labial palpi 4-jointed, the basal joint thrice the length of the second, the two apical joints minute, subclavate, and articulated near the apex of the second joint; paraglosse short and lanceolate ; maxillary palpi 6-jointed, the basal joint short, stout, and about half the length of the second joint, the rest filiform and decreasing in length. Thorax ovate; anterior wings with three submarginal cells, the second narrowed towards the marginal and receiving the first recurrent nervure in the middle; the third, which is rounded towards the apex of the wing, receives the second recurrent nervure at its apex; the posterior tibize and basal joint of the tarsi densely pubescent externally. Abdomen ovate, sometimes densely pubescent or with pubescent fascie. In some species the males have the intermediate legs elongated. Of the insects which are parasitic on A. acervorwm in the larva state, the first which claims notice is a species belonging to the Chalcidide, of the genus Melittobia of Westwood, with which the genus Anthophorabia of Newport is synonymous. The latter gen- tleman published a valuable and highly interesting memoir on this parasite in the ‘ Linnean Transactions,’ vol. xxi. p. 63. In the autumn of 1853 I had the good fortune of finding this inte- resting parasite in the cells of Anthophora. The female is a minute shining dark green insect, not more than half a line in length; the male is equally minute, but is of a testaceous yellow colour, having only rudimentary wings, and is not furnished with the usual com- pound eyes, but has in their place exceedingly minute simple eyes or ocelli, besides three true ocelli on the vertex of the head. This re- markable conformation was discovered by Mr. Newport, who has given ample details, the results of most elaborate physiological investigations, in the paper alluded to, Melittobia is here treated as the parasite of Anthophora, in accordance with the history of its habits as detailed by Mr. Newport; but when I discovered the larva it was feeding on that of Monodontomerus nitidus, a true parasite on the bee, which has been found in its cells feeding on the pupe. Having obtained a large supply of larve of the bee, and also of 188 APID®. Monodontomerus and Melittobia, ample means of observation were afforded, the result of which appeared to show that Monodontomerus is the true parasite of Anthophora, and Melittobia a parasite of Mono- dontomerus. Melittobia attacks indiscriminately the larve of both insects ; but in their natural situation I only found them feeding on Monodontomerus. Several cells were obtained containing larve of Melittobia ; but their victim was consumed; therefore it was not possible to determine satisfactorlly whether they had fed upon the Chalcididous insect or the bee. M. Audouin discovered Melittobia acasta in the nests of Osmia, Anthophora, and Odynerus: probably there are several species closely allied; for with insects so minute and belonging to a family in which a very general resemblance obtains, it requires a practised eye as well as a careful microscopic investigation before the specific differences can be detected. The mode of attack which these parasites practise appears to be made by several females obtaining entrance to the cell of the bee and attacking its larve, upon which they deposit their eggs, to the number of one hundred at least, which soon hatch. The young larve attach themselves to their victim, continuing to feed until full- grown, when they fall off and lie inactive at the bottom of the cell. By the time the whole brood is full-fed the larva of the bee is entirely consumed. The bees and the parasites appear in their perfect condition about the same time in the season, some haying passed the winter months in the larva state, others in their perfect condition. The genus Antkhophora has a world-wide distribution ; the number of species at present known is about one hundred and thirty, four only being found in this country. Dr. Dours, in his monograph of the genus published in 1869, enumerates one hundred and fifteen species, several from the islands of the Eastern archipelago and South America being unknown to him. The economy of the species varies considerably, some being true carpenter bees, others burrow- ers in the ground, in the mortar of walls or buildings, or in cliffs at the seaside. ‘They are subject to the attacks of numerous parasites, some belonging to their own order, others being coleopterous ; their nests are also frequently attacked by the general devastator, Morft- cula. This predaeeous and, indeed, omnivorous insect devours alike the store laid up by the bee for the sustenance of its brood, the larva, pupa, and also the perfect insect itself. Two bees are parasites upon the genus .4nthophora—Melecta luctuosa and M. armata—the former upon A. retusa, and the latter upon A. acervorum: the latter makes its appearance very early in the spring, as soon, infact, as the first wild flowers bloom; it may be sometimes observed early in March, attracted by the garden- crocus ; it continues to be found as late as July, and was captured in the Isle of Wight on the 15th of that month. The latter circumstance is explained by an investigation of a colony in the month of November, when a large portion of the brood will be found to have arrived at its perfect condition, the rest being still in the larva or the pupa state, the latter fast advancing to maturity; the — 15. ANTHOPHORA. 189 entire brood of the colony will pass the ensuing winter either as larvee or perfect insects ; none can withstand its rigour in the inter- mediate or pupa state. Those which remain larve until the return of spring advance to the perfect state very irregularly ; many will not become perfect until May, and a few probably not until June ; this will account for the species being found during so many months in one season. I have frequently had larve in an artificial condition (that is, in glass tubes or boxes) which have not changed until the second season, but am quite unable to account for such an apparent anomaly; how little, in fact,is at present known of the complete history of the Aculeate Hymenoptera! for, to use the words of Kirby, “So much knowledge, even with respect to a single genus, where the species are numerous, is not to be expected from one man.” But if each hymenopterologist would give faithful records of his obser- vations, the day will come when, by a combination of observations, an approach will be made towards a perfect knowledge of the his- tory, economy, and uses of each individual species.

B.M. Having changed the specific name of this species, I may state the reasons for so doing. In the first place, the authentic speci- men in the Linnzean Cabinet is undoubtedly the present species ; I have also ascertained that the next species, formerly considered the retusa of Linnzeus, is not found in Sweden, whereas the present insect is common. The two species may at once be separated by simply examining the calearia which arm the tibie; in A. retusa they are pale testaceous, in A. acervorum they are black. Mr. Kirby was not acquainted with the female of A. retusa; at least he con- sidered the Linnean typical specimen to be identical with A. acer- vorum; but on turning to the remarks on the Linnzean type in the ‘Monographia,’ we at once see the difference between it and the next species; Mr. Kirby says, “it is smaller, not quite so hairy, nor is its hair of so deep a black”—all characteristies of A. retusa, and not of A. acervorum. The synonymy of this and the following species is difficult to de- termine; the older authors were not apparently acquainted with both species. A. the difference in the two males is at once obyious, Mr. Kirby, with his acute perception of specific differences, at once detected this ; and although he was not so successful in separating the females (if he possessed both at the time of the publication of his monograph), yet in his collection he subsequently placed the true female with his A. haworthana. Dours has mixed the females ; for he says, the calcaria are sometimes black, sometimes testaceous. I have examined hundreds of the A. acervorwm, but never saw one with pale calearia. 1 have adopted such synonyma as I feel satisfied may be relied on. 2. Anthophora acervorum.

B.M. This bee is found in all parts of the United Kingdom. Extensive colonies are frequently met with; one of the largest I ever observed was in the chalk-pits at Northfleet; in the month of April so great were their numbers, that a dark flickering shadow was cast on the ground from the countless numbers assembled. ‘This is the “ wild bee” which Gilbert White observed in such numbers in the trenches of the Danish Camp, on Mount Carbon, near Lewes, which he de- scribes, in his‘ History of Selborne,’ as “dashing round the heads of intruders, with a sharp and hostile sound.” Anthophora acervorum is considered by some continental en- tomologists to be synonymous with A, pilipes, Fabr. I have taken great trouble in order to obtain the sexes of A. pilipes ; from France I have received a male very much like that of A. acervorum, but a female clothed with fulvo-cinereous pubescence ; the same have been sent from Westphalia and also from Copenhagen; in this country no light-coloured female has to my knowledge been taken. The parasite of this bee is Melecta armata, whose incursions are described by Shuckard as being very repugnant to it; he describes their attacking each other with fierce pugnacity. I have never wit- nessed any such combats, and imagine the circumstances must have risen from some temporary cause, and is not part of the natural economy of the insect. Two hermaphrodite specimens of this species have been captured: one was taken at Bristol, and is in the collection formed by the late Mr. Walcott of that city ; the second example was captured by myself in Apri] 1836, ina garden at Barnes. A description of this remark- able insect was published in the ‘ Entomological Magazine’; and two figures of itare given inthe third volume of the ‘ Zoologist,’ p. 890: in it the female character predominates; but one side of the face is male in colour, the antenne on that side being thirteen-jointed ; and the intermediate leg is male, the tarsi being elongated and fringed with long hair; the other legs are also male. 192 : APIDA.

B.M. This species appears about the end of June, and constructs its nest in banks, sandy cliffs, &e.; it frequents the deadnettle (Zamium purpureum), and is not uncommon in the vicinity of London. It in some respects resembles Saropoda bimaculata; its flight is rapid, and it makes a shrill piping sound similar to that of the latter insect. Dr. Nylander has examined the type of the Megilla quadrimaculata of Fabricius in the museum at Kiel, and has confirmed the suspicion of Kirby, expressed in his own interleaved copy of the ‘ Monographia,’ viz. that his Apzs vulpina was synonymous with that insect. 16.

Sexes three—males, females, and workers. The geographical distribution of Bombus is very extensive, its species numbering little short of one hundred, twenty being British. Although found both in the Old and New World, and in a few in- stances ranging into the tropics, Bombus only penetrates Africa as far as Oran ; it has not been found in Madagascar, Australia, or New Zealand. Wheresoever it occurs its parasite (Apathus) appears to ac- company it, although it is of rare occurrence in the tropics. The range of Bombus in the Old World is probably more extensive than that of any other Hymenopterous genus; it is found in Lapland, Siberia, Kamtschatka, North China, Syria, and Northern India ; and it has been found in Java, but that appears to be its southern limit, as not a single species has to my knowledge been found in the eastern archipelago. In the New World its geographical range extends to Greenland; Sir John Richardson found several within the arctic circle, at the Great Bear Lake; Captain Parry on his second voyage found two species at Boothia Felix. North America is rich in species of Bombi, and from Mexico some of the most beautiful species have been received. In South America we find it in Cayenne, and again on the Amazons at Para; further south it occurs on the Tapajos ; and crossing eastwards we find it again at Monte Video. The largest species known’ is found in Chili, 16. BomBUs. 194 Of the wild bees of this country the Bombi are certainly the most generally known; their size and sonorous hum necessarily attract every one’s attention. They are known under a variety of popular names: in Hampshire they are called dumbledors, in other counties bumble-bees or hummel-bees, and more generally in the present day humble-bees; in Scotland the brown moss-building species are called foggie-bees. ‘heir scientific name is simply an imitative one, and certainly very characteristic. No one in early spring can have failed to notice the loud hum of these insects as the females fly along hedgerows and banks in search of suitable spots in which to make their nests, or when after their hibernation during winter they seek the sweets of spring’s earliest flowers. Inthe month of May, when the horse-chestnut blooms, their hum among the flowers is heard from the break to the close of day. Great difficulty attends the discrimination of the species, and unless examples are in a state of good preservation it is only a waste of time to attempt to determine them; but no amount of exa- mination or comparison of specimens will at all times produce perfectly correct results. Of some species, such as the surface- builders (moss-builders as they are frequently incorrectly called), it is necessary to obtain nests and to breed the insects: the males are the most difficult to determine; but by an examination of the organs of generation they can be assigned to their respective species with undeviating correctness. During the last forty years I have endeavoured to obtain an exact knowledge of our native specyies,,and by obtaining nests and collecting innumerable varie- ties ‘inf which the sexes run, I hope to be able to remove some of the difficulties attendant on the study of these interesting insects. In some species the difference in the colouring of the males renders it impossible to assign them to their legitimate partners without the aid either of good descriptions or by obtaining them from the nests. An insuperable difficulty is met with when old long-exposed examples, having their original colouring entirely bleached and changed, are ex- amined; such may be deemed worthless and cast aside: but there is another difficulty, arising from the tendency to vary even in their original state of coloration. An instance of this kind is found in Bombus muscorum ; in this country it varies greatly, and ten species have been described from its varieties : examples from Denmark in- elude a black form, which is extremely rare in England, and has only been observed in small workers, but it occurs in all the sexes in the north of Europe. Similar differences occur in one or two other species ; B. subterraneus and B. soroénsis are examples of this : such differences led to no less than forty species being described out of less than half of the real number. The economy of the Bombi has been described in detail by numerous authors ; but the majority have contented themselves with reproducing that of J. P. Huber, who paid great attention to these bees, and whose observations are in most respects in accerdance with my own. However, I have never found the females hibernating in their old 02 196 APIDE. nests (I allude to the species that construct them underground) ; such may be the case in some instances or in other countries, but I have never succeeded in finding them thus domiciled. The situa- tions in which I have found them have been in the accumulation of rubbish, under clumps of furze, in the dry rotten wood of decaying trees, under moss in woods, and repeatedly under stacks of turf on commons ; in all such situations I have found them singly, never packed in clusters, as has been described. The females having passed the winter months in a state of tor- pidity are roused from their slumber by the warmth of the earliest spring days, and at once commence their life of unceasing labour. The burrowers underground are the first to appear and to seek for some cavity that may in some degree abridge their labour: a small one suits for the establishment of the colony ; but the enlargement of it as the nest increases in dimensions devolves upon the offspring. These bees are occasionally found with loads of earth attached to their legs, and I have seen them so overloaded as to be unable to take flight until they had freed themselves of part of their load. The parent bee, having found a suitable situation for her nest, collects quantities of pollen and honey, hoarding it up in a mass : having a sufficient supply she commences depositing eggs upon it; in a few days the larve hatch, and at once commence to feed on ‘the food on which they are cradled. At the side of the mass of food the parent bee also constructs receptacles called honey-pots, in which a coarse kind of liquid honey is stored: the use of this has been suggested to be for keeping the food of the larve moist; but in my opinion it is for the suste- nance of the working colony at such times as they are proves) by unfavourable weather from leaving the nest. When the larve are full-grown they spin a tough oval cv200n of silk, in which they rapidly undergo their transformation into the pupa state, and shortly afterwards acquire their perfect condition. The first bees developed are neuters, or workers. On emerging from the cocoons they are by no means in a mature state, fitted to take part in the labour of the community ; several days elapse before they acquire the gay livery they are dressed in when they quit the nest and commence their labours. Young females do not appear until the season is considerably advanced, and later on males make their appearance ; but the development of the various species differs considerably as to the time of the sexes being matured. My own observation in this respect leads me to the belief that B. pratorum first produces the males ; these I have found usually about the third week in May. It has been asserted that males of this genus having once quitted the nest never return to it. That they seldom do so may be strictly correct ; but I have seen the male of B. pratorum, B. hortorum, and also that of B. derhamellus enter their nests; and Mr. Kirby states, speaking of a male, “I have myself seen this insect entering the nidus of A. lapidaria.” The number of which the various communities consists varies very considerably ; but as a rule the burrowers underground have a popu- lation twice as numerous as the surface-builders. The numbers in 16. BomBUs. 197 the nests of the latter are greatly increased or diminished by the state of the weather: in fine dry seasons nests have double the number of inhabitants to what are found in them in wet unfa- vourable ones. A nest of B. sylvarum, found towards the end of August, had only three females, about half a dozen males, and a dozen workers, while several pupee were dead in their cocoons. This was after a wet summer and autumn ; the insects themselves, particularly the workers, were mere dwarf examples of the species. The average number of the population of B. muscorum, according to my observation, has been, in autumn when all the sexes are found, about 120; 25 of these were females, 36 males, the rest being workers. The division which is here named surface-builders contains those species usually called moss-builders or carder-bees, which are said to card or comb and cleanse the moss which they use in the construc- tion of their nests. Thus we find it recorded that “to these nests a moderately long arched passage is formed of the same material (moss) of sufficient size to permit the free passage of the bees to and fro.” The nest is described as having a “‘ vaulted covering, the inside of which is further strengthened by being plastered with a coating of wax.” Whatever may be the habits of these bees in other parts of the world, my own observations have failed to detect in any of the numerous nests of B. muscorum, B. venustus, B. elegans, or of B. sylvarum any plastering of wax inside the covering, neither have I observed any long arched passage leading to the nest. With regard to the materials used in the construction of nests, I have found usually an admixture of moss, but very frequently not a sprig of that material; bits of grass, usually the tender blades dried— in fact a smali bundle of hay has formed the covering, the blades on the inner surface being apparently more or less adhering, probably from the insects having bound them together with a gummy secretion or saliva. Several instances have come to my knowledge of the sagacity of these insects in making use of the nests of birds, and of their adapting them to their own re- quirements. One was recorded in the former edition of this work. Dr. William Bell observed the nest of a robin built in the porch of his cottage at Putney; some time afterwards he found that a humble-bee had taken possession of it, and had adapted it to its own purposes. Unfortunately the nest was destroyed before he had ascertained the name of the species; but, judging from the de- cription Dr. Bell gave of the bee, there can be little doubt of its being B. pratorum. Mr. Walcott, of Bristol, communicated a simi- lar account of finding the nest of a robin invaded by B. derhamel- lus, the eggs of the bird being covered with the accumulation of pollen and honey stored up by the bees. Mr. Walcott added to this account :—‘‘] have in two previous instances found broods of the same bee in birds’ nests.” Another correspondent gave me the following account of B. muscorwm:—*‘ This insect took possession of a wren’s nest at Holmbush, near Brighton; I had observed the bird building, and afterwards was astonished on finding that a bee 198 APIDE. had taken possession of the nest, and had, as I found, constructed its waxen cells amongst the eggs of the wren.” A very remarkable account of one of the brown bees was related to me by a lady, who observed it frequently flying into a stable through a latticed window: the bee was engaged in collecting a bundle of horsehair from a heap accumulated from currying the horses. Having made up a small parcel the bee flew off with it a short distance, and settled down with it among some grass. On examining the spot a nest constructed entirely of horsehair was discovered. This very interesting nest was unfortunately destroyed before the bee had quite completed its construction. An interesting feature in the history of the Bombi is the varied temperament of the different species, and the degrees of pugnacity with which some species will resent any attempt to invade their domiciles. Nests of the surface-builders may be taken almost with impunity, whilst such an outrage on the underground ones would be a dangerous undertaking. No species is more courageous than B. lapidarius, and B. virginalis is equally formidable. This relates to such attempts being made in the height of the season ; later, in the autumn, the bees lose their courage, and offer little if any re- sistance to attack on their habitations. - The Bombi have several parasites that invade their nests, and some of these must considerably reduce their numbers. The dipte- rous genus Volucella contains two or three species that feed upon their larve ; a species of the genus Conops is also said to do so, but I have never found them in the nests. The larve of Volucella some- times destroy the greater part of the brood ; the same species (V. bombylans) also feeds upon the larve of Vespide. The larve of Conops were found by Audouin in the intestines of B. lapidarius ; and Latreille states that Conops rufipes lives in the larva state in the abdomen of various species of Bombi, and that it there passes through its stages of transformation, and, on arriving at its perfect condition, it escapes between the segments of the abdomen. Ro- bineau-Desvoidy and also Léon Dufour have recorded similar obser- vations. MJutilla europea is parasitic in this country and through- out Europe on various species of Bombus; in England it has been found in nests of B. muscorum, B. lapidarius, and B. latreillellus. Hr. Drewsen, of Copenhagen, found it in the nest of B. scrimshi- ranus, obtaining from a single nest no less than seventy-six indivi- duals. Prof. Edward Brandt, of St. Petersburg, informed me that he had found Mvytilla in the nests of B. hortorum, B. lapidarius, and of B. muscorum. Although Mutilla is a parasite of Bombus, many species of that genus must infest nests of other genera of insects. About three hundred species of Mutillide are known, many of which inhabit countries where Bombus is not found. Numerous species of Mutilla are found in Australia, but Bombus is not found there, neither is it found in tropical Africa, where Mutilla is by no means uncommon. A few species of Coleoptera are common in nests of Bombi; they probably resort there for the purpose of feeding on the wax or the honey. Antherophayus nigricoriuis und pallens are frequently found 16. BomBUS. 199 in nests of Bombus muscorum, and Anobium pantceum I have ob- served in plenty in the same nests. Probably the greatest con- sumer of the wax is a species of Acarus ; these sometimes infest the vodies of the bees themselves in such numbers as to render them incapable of flight. The bee-parasites belonging to the genus Apathus are not uncommon in the nests of some species ; their para- sitism is treated upon in the observations on that genus. Section I. Swiface-builders. 1.

The pubescence of the entire insect nearly black. This is probably the most variable species of all the British Bomb: ; it is found in all parts of the kingdom, in Denmark and Germany, as well as other parts of the continent. It occasionally occurs nearly black in all the sexes. In England I have only seen workers of this variety. I have considered six of Mr. Kirby’s species to be varieties of B. muscorum, having repeatedly found them all in nests of this species. That the insect here described is the true Apis muscorum of Linneeus, is proved beyond doubt by an examination of the type specimen, which has the name attached to it in the handwriting of Linnzus ; it is in his cabinet, now in the possession of the Linnean Society. The parasite Mutilla europea was found in the nest of this Bombus last summer, by Miss Madeline Pasley, at Shedfield Grange, near Wickham, Hants; several nests were examined and the Mutilla was found ineach. This is the first time I have heard of this parasite being found in the nest of Bombus muscorwm. 2. Bombus agrorum. B, ater, hirsutus, thorace toto anoque ferrugineis. Bombus agrorum, Fabr. Syst.

In nests of Bombus muscorum I have found females of this species on one or two occasions; the species is much less common than B. muscorum. I included B. agrorum among the varieties of B. muscorum in the first edition of this work ; but finding the species plentifully last summer, I was induced to examine the generative organs of the males, and to compare them with those of B. muscorum, and feel satisfied that it is really a distinct species. 3.

Dr. Nylander having informed me that he had seen a specimen named by Fabricius Bombus senilis, and that in his opinion it was a faded example of the worker of B. muscorum, I have changed the name. It is certainly the Apis muscorum of Kirby, but not of Linneus. The name senilis is not characteristic of either the present species or of the Apis muscorum of Linneus, except of examples in a worn and faded condition. The specimen of 202 APID. B. senilis, named by Fabricius, in the Banksian collection is also a faded worker of Bombus muscorum. 4. Bombus elegans. B. hirsutus, ater, supra flavus, thorace fascia atra.

This species has hitherto been regarded as the Bombus fragrans of Pallas, which is a much larger insect and has dark brown wings. The bee has the same agreeable odour that suggested its name in the first instance ; but the descriptions of older authors are usually much too brief, and the size of a species is only occasionally given. This is a scarce species in the south of England, but has been occasionally taken at Hampstead, Shirley Common, Norwood, Lowe- stoft, Yarmouth, and on Durdham Downs, near Bristol ; in the north itis more common. I found its nest in Yorkshire, and on dis- turbing it the bees emitted a powerful aromatic odour ; the commu- nity, although it contained males and females, was small. 5. Bombus smithianus.

The male of Kirby’s A. donovanella is certainly that of B. derhamellus, as will be seen by an examination of his typical specimen. The species is generally distributed. I have frequently found its nests in hay- fields ; several occurred in a hay-field at Beaumaris, in Anglesey. The species iscommon. The bees make no defence when their nests are disturbed. 9.

The thorax with grey pubescence, with a black band beneath the wings. The worker I have not seen, but Schenck says it resembles the female ; he also observes that the male resembles a male Apathus. This is true; but the only male of that genus it resembles is that of A. rupestris, from which it is very distinct ; its elongate head and naked clypeus at once distinguish ‘¢ from that insect ; its antenne are longer and more slender. B. pomorumis the rarest species found in this country. I took three males in 1863, and my son a femalein the following year, near Deal. Panzer describes the basal segment of the abdomen as having white hair in the male, but in the figure it is coloured black. — 16. BomBts. 207 10. Bombus pratorum.

This is a very common species, particularly so in the north of England ; the male frequently making its appearance as early as the middle of May, it is usually the first Bombus of that sex that appears. The sexes are very variable in their colouring, so much so that the 208 APID. varieties have been described as constituting seven species; the normal colouring of the female is Kirby’s A. subinterrupta, and his A, burrellana that of the male. Ihave examined many nests of this species, which are frequently found in hay-fields, on mossy banks, and under furze bushes; they make little or no defence of their nests when they are disturbed. Apathus barbutellus is parasitic on this species. 11. Bombus cullumanus. B. hirsutus, ater, thorace antice abdomineque fascia flavis, ano fulvo.

I was formerly led to consider the male of this species to be a highly coloured variety of B. soroénsis ; but having captured speci- mens I have been enabled, by an exa‘nination of the sexual organs, to satisfy myself that they are distinct species. I have not any positive evidence of the female described being really that sex of the species ; but as it has been taken a’ the same time and place as the male, and as no other species ¢ Bombus is known to which this female could be assigned, I have no doubt as to the correctness of my con- clusions. The female most closely resembles that of B. pratorum, but can always be distinguished by the abdomen being shorter and broader, and by theblack band occupying one segment only. The male resembles that of B. pratorum ; but the general pubescence is shorter, ) 16. BomBUs. 209 the joints of the flagellum are subarcuate, the black band on the abdomen only occupies one segment, and the pubescence of the apical portion of the abdomen is bright ferruginous ; the yellow pubescence is of a paler and brighter colour. The species is un- doubtedly both local and rare. On one occasion I took four males and two females at Southend at the end of August; it must be observed that the male of B. pratorwm appears in May. The species has also been taken on the Brighton Downs and near Bristol. The worker is probably at present mixed with that of B. pratorum. 12. Bombus jonellus.

All the sexes were obtained from a nest found on the Grampians, Perthshire. This is a somewhat local species ; it has been taken at Coombe Wood, on Purley Downs, Shirley Common, and at Barmouth, North Wales. Mr. Kirby’s description is incomplete, so that it was difficult to ascertain to which species this male should be assigned ; but having myself seen his own interleaved copy of the ‘ Mono- graphia,’ I found that he had subsequently added, “ Facies ante an- P 210 APID 2. tennas palide villosus.” The type is afaded specimen. This species is readily distinguished by its short head from B. hortorwm, which it otherwise resembles. 13. Bombus nivalis.

Abdomen—the two basal segments with yellow pubescence: the third and fourth with black, and the apical ones with pale yellowish white ; beneath the pubescence is also yellowish white. B.M. This species must vary greatly in size: Dahlbom’s figure measures 12 lines ; Nylander gives the Lapland specimen at 16 ; and the largest T have seen from Shetland measures 9 lines. The colour of the pubes- cence must depend greatly on the exposure to which the insect has been subjected ; a bright yellow soon fades, Prof. Boheman sent a female from Sweden with the apex of the abdomen bright fulvous. All the sexes were obtained from a nest found near Lerwick, Shetland, in 1852, since which time no one has taken the species ; the nest con- tained about a dozen bees only, but fortunately all the sexes. In all probability the insect is not uncommon in Shetland, as the person who took the nest was not an entomologist, and did not know one bee from another. 16. BowsBts. 211 Section Il.

This is one of the most abundant of the British Bombz; it has its representatives in India, China, Japan, and Mexico. ‘The variety of the female haying a yellow collar is of very rare occurrence in England ; I have only seen a single example, which was taken near Sandwich, Kent. St.-Fargeau has described this variety as a distinct species, naming it B. lefebvret; I haye had an opportunity of ex- P2 212 APID A. amining his typical specimen through the kindness of Prof. Westwood, in whose possession are many of the types of Fargeau’s and also of Latreille’s bees. The species is common in Wales, Ireland, and Scotland; some of the finest examples have been obtained from the latter country. In Yorkshire this bee frequently constructs its nests in old stone-quarries ; but in the south I have usually found them in banks and at the roots of trees. The only instance in which I have observed the sexes of distinct species zm coitu has been a male of B, lapidarius copulating with a female of B. virginalis. 15. Bombus lucorum.

Var. 3. The four basal segments with yellow pubescence, with faint traces of dark bands. This is the Bombus ericetorum figured by Curtis. The typical specimen, a male, in the Linnean Cabinet is very like the variety 3. The typical specimen of Linné’s Apis terrestris, pre- served in the Linnean Cabinet, is the female of this species. In this country Bombus lucorum usually appears at an earlier period in the season, according to my observation, than Bombus virginalis. The latter is a rather larger insect ; its male is readily distinguished from that of B. lucorum by its always having the entire head clothed with black pubescence ; its maxillary palpi are different, and the second joint is longer in proportion tothe first joint. The nests of both species have been taken in autumn, when all the sexes of each species have been obtained. Ina nest of Bombus virginalis all the females had the apex of the abdomen tawny; but it is probable that when indi- viduals have been long exposed to weather, the tawny apex may become more or less bleached to white; I have found specimens of the female with the apex of the abdomen white. Ona female of Bombus lucorum being shown to the late Prof. Boheman, he named it B. terrestris of Linnzeus; whilst he pronounced the bee with the tawny apex of the abdomen to be a specie: nknown to him, and one not found in Sweden. In the type-collé ion of Kirby there is a female with a white anus, which, in his remarks on Bombus terrestris, he states to have been found by Mr. Trimmer in a nest of the bee with the tawny apex of the abdomen; this specimen is, in my opinion, an example of B. lucorum. It is not an unusual occurrence to find individuals of one species in a nest of another ; thus I have found B. sylvarwm in a nest of B. muscorum; such oc irrences can only be regarded as accidental. The yellow bands in B. lucorum are of a lemon-coloured yellow, whilst those of B. virginalis are deep orange-yellow. It should be mentioned that the male organs of B. lucorum and of B. virginalis have been compared ; and although the differences are only*slight, yet they are constant, and in my opinion quite justify their separation as distinct species. 214 APIDE. 16.

Its nests, as far as my experi- ence enables me to judge, are more populous than those of any other species (perhaps B. lapidarius excepted); in one nest I found 107 males, 56 females, and 180 workers; and some of the latter sex were probably on the wing when the nest was taken—late in the evening in the month of August. Apathus vestalis lives in company with this species. 17. Bombus hortorum. B. hirsutus, ater ; thorace antice, scutello abdominisque basi flavis, ano albo; capite elongato.

The specimen described by Fabricius, from Madeira, is larger than any European one that I have seen; but the series of examples from that island in the British Museum clearly shows that the insular specimens vary in size:like the European. 18.

BM. Var. 3. The black fascie on the abdomen subobsolete, the abdomen and thorax beneath subcinereous. The female and worker of this species most closely resemble those of B. subterraneus; but their pubescence is shorter, and the apical margin of the second segment has always a more or less distinct fringe of white pubescence ; the pubescence on the abdomen of B, subter- raneus is somewhat shaggy, which is not the case in the other species. The males are readily distinguished ; the distinctness of the two species is confirmed by the different form of the male orgaus. I have taken all the sexes from the nest, and found Apathus ves- talis living in the communities. The female described by Kirby is that of B. subterraneus; so also is var. /3; var. yis the female of B. latreillellus ; var. 6 is a worker of the same ; var. e is another female of B. subterraneus ; but there isa second var., e, which is a worker of B. latreillellus; in the Kirbyan type-collection are also four other workers of the same species. This insect is not common in the vicinity of London, but very abun- dant in many localities, particularly so at Folkestone, Dover, and Deal. Several nests were found at Lower Walmer, from which all the sexes were obtained. The nest was situated at the end of a tunnel between three and four feet in length, which ran up a bank, not being more than four or five inches beneath the surface. The nest itself was about a foot and a half from the surface. 20. Bombus subterraneus. B. hirsutus, ater, thorace antice flavescente ano griseo-fusco aut fusco-lutescente. Bombus subterraneus, Fabr.

The most highly coloured variety of the female resembles closely that of B. hortorum ; but the species is larger, the abdomen is not so angular at the apex, and the pubescence is shorter; the tongue is proportionally considerably shorter ; every gradation in colour, from the form described to the totally black one, is to be traced; and Kirby’s typical specimens prove the correctness of the synonymy given. The pubescence of the species is shorter and also coarser than in B. hortorum. The male is equally variable as the other sexes, its highly coloured form greatly resembling the male of B. hortorwm; but its pubescence is shorter, and the curled fringe of hair on the mandibles is ferruginous. These hairs are frequently discoloured by the nectar of flowers ; but when free from discoloration they are red; in B. hortorum the fringe is dark, almost black. The sexual organs of the black and coloured males are identical in form. 17. APATHUS. 219 This species is common in many localities, and usually all the varieties occur at the same spot; I have taken the black male in coitu with the yellow-banded female. This is one of the most protean species of the genus, and a familiar acquaintance with these insects is necessary to enable any one to separate all the sexes from the closely allied species. I have seen St.-Fargeau’s typical specimen of his B. soroénsis ; and it is certainly a female of B. subterraneus. Genus 17. APATHUS. Apis (pt.), Fabr. Ent. Syst. ii. 317 (1793). Bombus (pt.), Fabr. Syst. Prez. 342 (1804). Bremus (pt.), Jurine, Hym. 257 (1807). Apathus, Newm. Ent. Mag. ii. 404 (18534). Psithyrus, St.-Farg. Hym. ii. 424, nec Hiibner (1841). The generic characters are those of the genus Bombus, with the following distinguishing differences. The posterior tibie exteriorly convex, pilose, and not furnished with a corbicula for conveying pollen, only slightly widened towards the apex ; the basal joint of the posterior tarsi not toothed at its base above; the abdomen incurved more or less at the apex, convex, and subglabrous; the apical ventral segment with its lateral margins elevated. The pos- terior tibize of the male very convex, and only slightly attenuated at the base. The geographical distribution of the Apathi is presumably co- extensive with the Bombi; if this is the case, much remains to be discovered, since, at the present’time, no species has been brought from India or China, although several species of Bombus are known to inhabit those countries. A single species has been found in Brazil, two or three in Mexico, two in British Columbia, one in Vancouver’s Island, and seven in North America ; in Europe we are acquainted with five species, four of which are found in this country. St.-Fargeau established this genus under the name of Psithyrus, a name preoccupied in Lepidoptera; Newman’s name Apathus (signifying want of affection, from the circumstance of their leaving their offspring to be nurtured by the industrious Bombi) is exceed- ingly appropriate ; it has the priority and is consequently adopted. The species found in this country do not confine their parasitism to one species of Bombus ; or, if there is an exception to this, it is in the case of the Apathus rupestris, which hitherto has, I believe, only been observed in the nest of Bombus lapidarius. A. campestris has been found in the nest of B. hortorum and B. latreillellus ; A. bar- butellus frequents the nests of B. pratorum and of B. jonellus ; A, vestalis those of B. virginalis and of B. lucorum. These bees are the only parasitic ones that greatly resemble their hosts; and this close resemblance is probably requisite to enable them to enter the nests of the Bombi without molestation. The structure of these bees marks them out as the aristocracy of the 220 APIDE. humble-bees ; their legs are not furnished with baskets in which to convey the fruits of labour to the nests, as is the case in the laborious Bombi; their race consists of males and females ; workers they have none. The Rev. Mr. Kirby was the first entomologist who recorded his detection of the structural differences observable in the Apathi. His statement is* :—*‘ After my ‘ Synopsis ’ was printed I discovered, what had escaped me before, that four different species, one of which had a yellow, two a white, and one a red anus, were deprived of some of the characters of the Bombinatrices, having neither corbicula, nor pecten at the apex of the tibizw, nor auricle at the base of the plant of the posterior legs, at the same time exhibiting some pecu- liar to themselves.” Mr. Kirby does not appear to have suspected their parasitism ; in his remarks on Apathus vestalis he says :—“ The posterior tibiz of one specimen in my cabinet is covered from one end to the other with a thin coat of pale earth, mixed with particles of sand; they probably use this in constructing their nests or cells.” He further adds :—* It is remarkable that the females and neuters of these Apes should exhibit those characters which are peculiar to the males of the rest of the family.” The mention of neuters in the passage quoted is clearly an oversight, as no description of one is to be found in the ‘ Monographia,’ neither is one to be found in Kirby’s type-collection. Although these bees very closely resemble the working Bombz, they are much less pubescent, their abdomen being smooth and shining; they live in perfect harmony together, and issue from and enter the nests without let or hindrance. Shuckard says they have two broods in the year. Upon what data this statement is made does not appear; my own observations have not led me to adopt this opinion. Like the Bombi, the females hibernate during the winter months in a torpid state, and reappear in spring—usually, according to my experience, a little later than the Bombi, these being consequently the brood of the previous season. No males are developed until the middle of summer, their number increasing until the autumn, when they are frequently found in great numbers: at this time the great brood of females appear,which, after being ferti- lized, soon retire to winter quarters. The Apathi are principally found in the nests of such species of Bombz as construct their nests underground. Although one species (A. barbutellus) has only been found in the nests of B. pratorum and B. jonellus, it probably frequents other communities ; but it has not been observed to do so. Apathi have not been found in nests of B. venustus or of B. sylvarum to my knowledge ; it is therefore apparent that their presence cannot be necessary for carrying out any phase in the economy of the Bombz. * Mon.
