And therefore I believe never any man yet did, never any man shall, so long as the world endures, by his utmost industry, attain to the knowledge of all the species of Nature.’—Joun Ray. Oxford: AT THE CLARENDON PRESS. M.DCCC. LXXIV. MCZ LIBRARY HARVARD UNIVERSITY CAMBRIDGE. MA USA ADVERTISEMENT. Tue donation made to the University of Oxford by the late Rey. F. W. Hops, of his entire Collections and Library of Natural History, and the subsequent acquisition of the Burchell, Wells, and other Collections, including also my own, have enriched the Univer- sity Museum with a large number of new and rare species of Insects, from which it has been considered advisable that a selection should be made for illustration in a manner worthy both of the donor and the University. In making this selection I have considered that it would be most beneficial to illus- trate certain Groups or Families rather than isolated Species. With this view the Groups of Goliathidee and Cremastocheilidee have been selected ; a complete Monograph of the latter being given, with figures of upwards of one hundred Species. Of the singular Family Paussidze upwards of fifty Species are figured for the first time, together with many other curious Coleoptera. Many remarkable Groups and Species belonging to the Orders Hymenoptera, Orthoptera, Neuroptera, Hemiptera, and Lepidoptera, as well as several singular Apterous Groups, are also given. The Plates are engraved and coloured from drawings and dissections prepared by myself. I have considered it due to the memory of Mr. Hors to reprint the late Dr. Prrt- crews Biographical Notice of him, together with a concise account of the Collections presented by him to the University of Oxford, and a list of his published Works and Memoirs.

PETTIGREW, Eso., F.R.S., F.S.A,, PHIL. DOCT. GOTTING, V.P. AND TREAS. OF THE BRITISH ARCHHOLOGICAL ASSOCIATION, From the Address delivered at the Annual General Meeting of the Association, May 13, 18638. I now arrive at a name in the obituary of the year at which we must all repine, the Rev. Freperick Winiiam Hors, M.A., D.C.L., F.R.S., etc., one distinguished in private life by his most amiable and benevolent character, and who in public will ever be regarded as a distinguished contributor to natural science, and the founder of a much-needed Profes- sorship in the University of Oxford. I look back to a period of thirty years’ communion and friendship with pride and satisfaction, and the regret I feel at his loss is commen- surate with the gratification and information I derived from his society. The Rev. Mr. Hope was born on the 3rd of January, 1797, in Upper Seymour Street, Portman Square. He was the second son of John Thomas Hope and of Ellen Hester Mary, only child of Sir Thomas Edwardes, Bart., of Ealing, Middlesex, and Netley, Shrop- shire. Mr. Hope received a portion of his earlier education from an old and respected friend of mine, the Rev. Mr. Delafosse, of Richmond ; after which he was entered at Christ Church, Oxford, where he graduated as B.A. in 1820, and took the degree of M.A. in 1823. His health was always delicate, but his activity was great; for his mental energy was sufficient to carry him through any object which called for his attention. He selected the Church as his vocation, and was ordained to a curacy at Frodesley, Shropshire, one of the livings in the gift of his family. The pursuit of natural history was, it may be said, a passion in which he indulged from the earliest period of his useful life. Under c Xviil OBITUARY NOTICE OF THE Dr. Kidd, at Oxford, he studied geology and other branches of science with great ardour ; but the chief department of natural science to which his attention was directed was Entomology, in which branch, I may be permitted, without fear of contradiction, to say, he was the most highly qualified of his day. I state this upon no less an authority than that of the late Rev. W. Kirby, F.R.S., who gave to me personally this character of my friend. I could state many circumstances in proof of this assertion, but I will content myself with recording one which occurred to me at a time when I was paying much atten- tion to the processes of embalming adopted by the ancient Egyptians. In the examination of one of the mummies—that of which I have given a representation and particular descrip- tion in my work on this subject, published in 1884—I met with a quantity of débris that had simply the appearance of so much dirt mixed up with minute fragments of wings, legs, and other most diminutive parts of insects. I placed this mass before him in the presence, I recollect, also of our distinguished associate and vice-president, Sir J. Gardner Wilkinson, F.R.S.; and Mr. Hope immediately, without being apprized whence it had been obtained, pronounced the mass to be composed of insects whose natural food was animal matter, which he deduced from the apparent structure of the mandibles, and the forma- tion of the limbs. It was, in fact, the remains of insects which had been feeding upon the ancient Egyptian during his embalmment, and whose labours, together with their existence, had been brought to an end by the heat and medicaments employed in the conservation of the form of a human mummy. What Baron Cuvier and Professor Owen have been able to accomplish in the building up of a mammal, or a bird, or other animal from a single bone, Mr. Hope could do with a portion of wing, or limb or wing-case of an insect. I always derived much assistance from his vast entomological knowledge, on the occasion alluded to as well as in other objects of pursuit ; and in examining some heads brought for me from Egypt by Sir Gardner Wilkinson, we found contained within the skull of one, a number of insects in various stages of their existence, that had most probably first drawn their vitality within the head, where the ova had been, during the process of embalming, deposited, and the whole being afterwards bandaged up and all exit closed, there they were born, passed the short period of their life, exhibited themselves in different states of their progress, and became ultimately embalmed within the skull, which formed for them the cradle of their birth and the tomb for their dead remains. Mr. Hope was able to mark all the distin- guishing appearances of these insects; and as although the genera to which they belonged was known, yet not the precise species, we agreed to name them, from the peculiarity of their situation and circumstances, Necrobia mumiarum and Dermestes pollinctus. The present Professor of Zoology at Oxford, J. O. Westwood, Esq., made a drawing of these in their natural and magnified forms, their larva, ova, etc., which I now lay before you, and which I had engraved in the work before alluded to, and I offer it as an evidence of Mr. Hope’s intimate acquaintance with entomology. It is not remarkable that Mr. Hope should have been early admitted into the fellow- ship of the Linnzean Society and many other societies abroad established for the promotion REV. FREDERICK WILLIAM HOPE. xix of natural history. These connexions led him to a very extensive correspondence with eminent professors and other distinguished persons ; and being happily endowed with ample means to indulge in any pursuit of which he might make choice, he readily obtained from, I may say, almost every part of the world, specimens which led him to form a cabinet which was the envy of many, and the delight of all. I well recollect this rich collection as depo- sited in Seymour Street, and witnessed with wonder the variety and splendour of this department of animated nature. In this museum were to be found assembled and associ- ated naturalists not only of this but of many foreign countries, and conversazioni held of the most interesting character. This rich museum is now, by the liberality of Mr. Hope, deposited at Oxford. It was given to the University in 1849; and upon occasion of laying of the first stone of the New University Museum, in 1855, Mr. Hope was justly distinguished by having conferred upon him the honorary degree of D.C.L. ‘To this collection he may be said to have continued to make additions up to the time of his decease, although the latter years of his life were passed under sufferings of ill health of a very severe description. But his mind was of too vast a character to limit his researches to one department : he made collections in all the branches of natural history, and he purchased large and entire collections, among which may be mentioned Mr. Hubbard’s, of Orkney birds ; Professor Bell’s, of reptiles and crustacea; Mr. Westwood’s, of insects, books, and drawings ; and Mr. Wollaston’s, of the insects of Madeira. These vast accessions have all been added to his munificent gift to the University of Oxford, rendering the entire collection unrivalled, if we except those in the national collections of London, Berlin, and Paris. Mr. Hope was acutely sensible that, however valuable and desirable such collections must be to the students of his Alma Mater, yet that their value and importance would be very ereatly diminished unless a professorship should be established specially devoted to their considera- tion. Hitherto there existed no chair for the teaching of zoology. With his collections, therefore, he endowed a professorship of £4001 per annum, by which his name will be handed down to posterity as a great benefactor to his university and his country. The nomination of the professor was left to Mr. Hope during his life, and as the first occupant of the chair he nominated Mr. J. O. Westwood, a name well known to all naturalists, and one, also, with which archzeologists are in no little degree acquainted. Mr. Hope also appointed Mr. Westwood the Curator of the Museum. Mr. Hope was a good scholar, and his Latin compositions were elegant. That his tastes * [‘ For this purpose Mr. Hope endowed the Professorship of Zoology with the capital sum of £10,000 New 3 per Cent. Annuities. Mr. Hope died in the early part of 1862, and shortly afterwards his widow, in fulfilment of his intentions, transferred to the University a second sum of £10,000 in the same Stock, and assigned one-third of the dividends to the Professor in augmentation of his stipend. Mrs. Hope assigned another third part of the dividends as a stipend for the Keeper of the Hope Collection of Engraved Portraits, and directed the remainder to be applied in equal portions in keeping up and increasing the two Hope Collections. In December, 1864, Mrs. Hope gave a further sum of £1666 13s. 4d., in the same Stock, to augment the stipend of the Keeper of the Engravings, for the purpose of enabling him to employ an Assistant, and to meet expenses incidental to his duties. —Latract from the Oxford University Calendar. | Cc 2 XX OBITUARY NOTICE OF THE should lead him to indulge to a certain degree beyond the range of natural objects is not surprising; and in collecting the portraits of distinguished naturalists, he was led also to those who had eminently cultivated other branches of science, the arts, and literature, and in the course of time led him to the formation of a most remarkable collection of engraved portraits and topography, consisting of more than 200,000 specimens. The portraits have been estimated to be not fewer than 140,000, and the topographical engravings nearly 70,000, whilst the engravings in natural history are between 20,000 and 30,000 in number. The portraits are arranged, according to the subjects for which the individuals were peculiarly distinguished, in Solander cases, the larger in portfolios and guard books. These have all been given to the University of Oxford, and are open to the inspection of the public, for which he anxiously stipulated. He has been no less liberal in regard to his vast collection of drawings in natural history and topography, and to these are attached his books, forming a very extensive library of works in all branches of natural history, which serve to elucidate his museum. I recollect that when in London, I have seen him at his daily occupation, devoting himself to a case of insects, for they required attention at least once a year to be preserved from destruction—so fragile is their nature. He had a case, he used to tell me, for every day in the year; and latterly, in the arrangement of his engraved portraits, etc.,’ he was happy in having as his assistant his amiable and enlightened partner, whose unde- viating attention to his pursuits and constant care of his health under great infirmity were the admiration of all who had the happiness to enjoy their society and friendship. Of the Entomological Society of London Mr. Hope was a founder, and he published various papers in the Transactions of that Society ; also in the Proceedings of the Linnean Society; and a distinct work, in three volumes 8vo, on the Classification of Coleopterous Insects. Highly gratifying as it would be to me to dwell upon these researches, I must yet forbear, as they do not come under the denomination of those to which our attention is particularly directed. I cannot, however, withhold the mention of a work which is only in MS. at present [as it is still in 1874], but which I trust may some day be put before the public, as interesting to all classes and to all readers—his Entomologia Sacra—in which the character of, and the antiquities connected with, all species of insects referred to in Holy Writ are most precisely and learnedly discoursed of. Mr. Hope was most liberal in his communications to other naturalists, and it would be difficult to form any estimate of the aid given by him to many authors in the production of their works!. Looking over some of his MSS.—many of which are fragmentary, but of considerable value, left to the University, and I may venture to hope to form the nuclei of future essays—I found one, in rough notes, of contributions rendered to the late amiable 4 [In proof of this statement it may be mentioned that Mr. Hope’s name appears in almost every page of Graven- horst’s work in 3 volumes, ‘Ichneumonologia Europea, 1829, as a contributor of British Species of Ichneumonide, which he had collected to a very large extent. In like manner his name appears as a very extensive contributor of exotic species of Curculionidae to Schonherr’s Work on that Group, in 14 volumes ; and also in M. Gory’s great works on the Cetoniide and Buprestide.—J. O. W.] REV. FREDERICK WILLIAM HOPE. Xxi Mr. Kirby, for his admirable Bridgewater Essay. Many have readily acknowledged the services Mr. Hope had rendered to them. Mr. Yarrell takes special notice of the assistance he had received in his works on British Birds and Fishes ; Mr. Stephens on Lnglish Insects ; Dr. Royle in his work on the Himalayas ; in the remarks on the Entomo-geography of India, and others at home and abroad. He was a Fellow of the Royal Society, of the Linnean, took a warm part in the establishment of the Zoological Society [1826], and was elected President of the Entomological Society [1835]. Many foreign academies and societies en- rolled his name in their lists, and we have had the honour of his name from the commence- ment of our labours. I look back with pride at having introduced him into our Association ; and for a short time he was a member of our Council. Had his health permitted of a con- tinued residence in England, we should doubtless have benefited much from his exertions. We had, however, the great satisfaction of seeing him at our Congress at Shrewsbury, and he was present on occasion of our visit to Uriconium. I had the pleasure of passing a week with him, after that Congress, at the seat of his brother, Mr. Hope-Edwardes, at Netley in Shropshire; and it is with much gratification we find that gentleman’s name in the list of our Associates. The state of his health rendered a residence abroad absolutely necessary to him ; but he followed up with unabated assiduity his attention to natural history. Nice, the climate of which appeared to be congenial to his frame, offered him abundant opportunities of col- lecting fish and crustacea to add to his collections. At Naples, in 1851, he printed a Catalogue dei Crostacei Italiani e di molti altri del Mediterraneo, which is highly im- portant in regard to the identification of species and the establishment of their habitats. Many of these are for the first time recorded and named. He also published in Italian Descrizione di aleune Specie d’ Insetti Fossil’, in a memoir presented to the Academy degli Aspiranti Naturalisti in 1847. Mr. Hope’s zeal sustained him to the last; but nature was exhausted, and on the 15th of April, 1862, at the age of sixty-five years, he expired. To a naturally weak system, I fear his subsequent ill state of health to have been much produced by his energetic tem- perament, his eagerness in the pursuit of knowledge, and particularly in his researches in Holland, where he was attacked with ague in a virulent form. From that time I sensibly observed his failure: he also, in making collections at Nice, met with an accident, fell into the water, and barely escaped with life. All told now heavily upon him, yet his desire to improve and add to his collections was constant; and, when unable any longer to move about, he was to be found examining catalogues and sending commissions to sales, to render complete those vast accumulations which will serve to hand down his name to posterity with honour and approbation.

Col., p. 69), which is probably nearly allied to Delinius ; but it is described as resembling a large Stomis, but broader, with more oval elytra, and with triangular-formed palpi and filiform antenne.

From a sketch which I made of the type specimen of G. albosignatus of Boheman in the Stockholm Museum, I am able to state its identity with Dr. Kirk’s insect, the frontal horns in the former specimen having been broken off by a gun-shot, the specimen having been fired at whilst flying. I am indebted to Dr. Kirk for the following note on the locality of his specimen now in the British Museum. ‘The Goliath was found under exceptional circumstances in an out of the way place not likely to be visited by white men for some time again. It was in exploring Kebrabassa, in which trip, except Dr. Livingstone and myself, every man on the expedition was done up and turned; and he says that this was the worst journey he ever had in his life. The season was November, just before the rains had set in, although the first showers had fallen. The beast was crawling on the rocky ground among the few inches of parched grass-stalks which remained. Thus I did not find it in its native habitat. I think it ought certainly to be found along the slopes near where the Mission was. There the climate is nearer to what it was where I got the insect than anywhere else: high hills of schist rock barely wooded, damp at one season and dry at another. The vegetation is nearly the same, but Kebrabassa has some features slightly distinct.’ The head of the male, seen laterally, is represented in fig. 2a, the maxilla of the same sex at fig. 24, shewing the unarmed mando and the obtusely bidentate galea, and the broad mentum, deeply notched in the porrected middle of the anterior margin, at fig. 2c. The specimen figured is contained in the Collection of the late J. Aspinal Turner, Esq., of Manchester. Srecrrs 2—GOLIATHUS HIGGINII. Westw. Prats JI, Fie. 7.

One of the maxille of the female is repre- sented in fig. 7, shewing the acute apical spine of the mando, and the two deflexed teeth of the galea; and the mentum in fig. 7a. The latter is contracted at the base, and has the fore margin slightly produced in the middle and not at all incised in the centre. This peculiarity may possibly indicate other peculiar character- isties in the male, which may render it necessary to separate it subgenerically from Goliathus proper, when it shall be discovered.

It has the fore tibie armed externally with three acute teeth, and each of the four posterior tibiz is armed with a spine a little beyond the middle. The maxilla is terminated by an acute galea, strongly setose above, and the mando by a very sharp spine. (Fig. 6 a.) Genus novum—ASTHENORHELLA. Westw. Mas.

They have a stria on each side of the suture, and another (anteriorly abbreviated) at the end of the inner red patch. Between the two red patches, which are very convex, glossy, and almost impunctate, there arise four plain strie, between which and the lateral margins are several very irregular rows of punctures. Beneath, the body is black, glossy, and slightly punctured ; the cox of the fore legs are clothed with fulvous hairs, the hind coxe are striolate- vermiculate ; the three basal segments of the abdomen have a transverse fascia of luteous scales, interrupted in the middle; the hind femora are obliquely striolated.

The dissections accompanying the figure of this species are taken from the unique specimen of the male in the Hopeian Collection. The mandibles (fig. 3.2) have the upper edge of the basal portion and the outer edge of the horny knife-like external part setose. The maxille (fig. 34) have the upper edge of the flat square mando and the galea densely clothed with long hairs; the mentum (fig. 3c) is obconical, notched on each side below the anterior rounded angles, for the reception of the palpi; the anterior margin is widely but not very deeply emarginate. The markings on the upper surface of the body are produced by squamosity, and are not at all clearly defined. The legs are long and slender, the fore tibiw have two sharp teeth at the extremity, and a third much shorter between the base and the middle; the middle tibie are rather short and much curved, and the hind tibie are long and straight; the tarsi are long and slender.

This group, by means of such genera as Uloptera and Macroma, is related to the more typical Cetoniide, through such genera as Diplognathus and Anoplocheilus, with which indeed Mr. MacLeay united the more aberrant Cremastocheilides (in his memoir on the South African Cetoniide) ; whilst the more typical Cremas- tocheilides were formed into a separate group, Cryptodinus, with Cryptodus as the leading genus. This last- named genus however, as I proved by careful analysis in a memoir published in the fourth volume of the Transactions of the Entomological Society of London (1845-1847), belongs to the Dynastidi, and is in no wise related to the Cremastocheilides except in the obscure colours and flattened form of the species. In the Berlin Museum another Dynastideous genus is also arranged with these inseets—Cryptodontes Dej. Burm. (Lepto- gnathus Westw.)—the anatomical details of which I have also elucidated in the same memoir. But very little is known of the habits of the insects of this family. Dr. Schaum found one specimen of Cremastocheilus canaliculatus in the nest of a large black species of ants on the Catskill Mountains; and Professor Haldeman, in Pennslyvania, found several specimens of two species in ants’ nests. Herr Guienzius found Cwnochilus setosus in ants’ nests, the individuals being covered with the ants, which seemed to suck from them a gummy exudation. He also discovered Scaptobius aciculatus in ants’ nests, in company with Paussus cucullatus ; also specimens of Lissogenius were found by him in similar situations. Orper—COLEOPTERA.

XXXIX, Handb. iii. 1842, p.625 ; Lacordaire, Gen. d. Coleopt. Atlas pl. XX XIX, fig. 2. This singular genus, founded upon a single species, U. planata, from Cayenne, seems to hold a situation between the Cetoniides and Cremastocheilides. In the ‘ Handbuch der Entomologie’ it is placed between the Diplognathides and Cremastocheilides. It has the antenne 10-jointed, with a 3-jointed club. The eyes are partially incised; the maxille have the mando terminated in an acute point, whilst the galea is small and bidentated. Respecting the palpi, Burmeister observes :— ‘Palpis maxillaribus’ (see my plate VIII, fig. 2), ‘ secwriformibus, inter omnia Melitophila hoc genus potis- simum notatur.’ The mentum is dilated at the sides, which are strongly ciliated; the labial palpi are minute, with the last joint acute; the mesosternum is produced into a dilated flattened process, truncated in front. The abdomen on the ventral surface is 6-jomted ; the legs short, with the fore tibiae obtusely tridentate on the outer edge. Species unicA—ULOPTERA PLANATA. Burmeister, 1. e.

Caput parvum supra planum. Antenne 10-articulate, clava 3-phylla. Mandibule parvee bipartite extus cornes apice producto acuto, parte interna breviori membranacea rotundata, basi in dentem magnum molarem dilatata. Maxill (fig. 1) parve cornee, mandone in dentem parvum producto, galea parva, cornea apice oblique truncato, vix bidentato. Palpi maxillares parvi, vix ultra apicem maxillarum extensi, articulo ultimo ovali. Mentum lateribus basi dilatato-angulatis setosis ; medio disci impresso et circulariter striolato. Palpi labiales minuti, articulo ultimo ovali (fig. 14). Prothorax brevis latitudine longitudinem excedente, lateribus rotundatis, margine postico ante scutellum emarginato; seutellum elongatum, postice attenuatum. Elytra thorace latiora, regione suturali depressa, medio disci longitudinaliter sinuato-elevato tuberculisque elevatis instructo. Prosternum in cornu deflexum truncatum ante pedes anticos productum (fig. 1d lateraliter et le subtus visum). Mesosternum inter pedes intermedios paullo porrectum, latum deplanatum, lateribus parum angulatis (fig. 1/subtus, 1g lateraliter visum). Abdomen subtus convexum. Pedes breves; tibiis anticis triquetris, margine externo obtuse tridentatis (fig. 1 ¢ lateraliter visis). This genus is closely allied to Uloptera, but is at once distinguished by the minute size of its maxillary palpi, on which organs, as stated above, Burmeister lays the greatest stress in the characters of his genus. The prosternal process is also quite distinct, being described in Uloptera as ‘planum, latiusculum.’ This character in Phymatopteryx evinces a strong relationship to many of the Cremastocheilides, whilst the irregularly raised disc of the elytra especially recalls to mind the Genera Ptychophorus and Rhagopteryx. The African habitat of the type of this genus further removes it from Uloptera. Sprcres unrca (2)—PHYMATOPTERYX SCULPTILIS. West. Puate VIII, Fie. 1.

Dr. Schaum (in a letter to me of October 28, 1848) says: ‘I have lately obtained two specimens of Macroma Abyssinica, and seen about a dozen more in the Senkenberg Museum, in Frankfurt, taken by Ruppel. I have Famitry—CETONIID 4. Sus-Famity—CREMASTOCHEILIDES. 9 compared them very carefully with my specimen of Macr. confusa, Hope (scutellaris, Gor. et Perch.), from Senegal, and do not find any difference. Macroma Abyssinica must therefore be sunk. I have no doubt, by comparing Mr. Hope’s specimen of confusa with that of Adyssinica in the British Museum, you will come to the same conclusion.’ The specimens from Abyssinia, to which I applied the MS. name MW. Adbyssinica, are smaller than all the others from South Africa, Natal, and Zulu, being only 7} lines long. I can, however, discover no other specific distinction. Sprecres 3 (5)—MACROMA COGNATA.

No figure has hitherto been published of this pretty species. The basal joint of the antenna is rather dilated. The apex of the clypeus is emarginate, having a trans- verse elevated line close to the apex. The maxilla (fig. 3 a) in both sexes has the inner lobe armed with three teeth, of which the upper one is the largest, and the inner one scarcely prominent. The mentum (alike in both sexes) is emarginate on each side opposite the insertion of the labial palpi (fig. 34), and the anterior tibia of the male (fig. 3 c) is narrower and less strongly toothed than that of the female (fig. 3 @).

The smaller and narrower size of the insect, and especially the form of the yellow spot on the pygidium (fig. 54), and the rich chestnut coloured stripe on each elytron, well distinguish this species from its immediate allies. The mentum is light chestnut coloured; it is much angulated in the middle ; the apical portion (fig. 5a, head seen in front, concealing the basal portion of the mentum) being broadly cordate, the front margin being but slightly emarginate. The middle of the thorax, in front of the scutellum, is but slightly impressed. Species 6 (8)—MACROMA EMARGINICOLLIS. Puate VI, Fie. 11.

Lam. Melit. p. 60 ; Boheman, Ins. Caffr. pars ii. p. 45. This species is at once distinguished by the deeply emarginated hind margin of the prothorax. The man- dibles have the outer blade considerably elongated (fig. 11 a). The maxille have the upper lobe forming a very acute sickle-shaped tooth, and the lower lobe is acutely bidentate with several spinulose sete on the inner margin (fig. 114). The mentum is oblong, with the apical half oblique and the apex nearly truncate (fig. lle, 11d, the same seen sideways). The mesosternum is broad, rather rounded in front, obtuse (fig. 11/), and but slightly porrected (11 e, seen sideways). The anterior tarsi are 5-jointed, but the basal joint is con- cealed above by the produced extremity of the tibia. The punctures on the dise of the elytra form transverse curved lines, and they are very crowded together at the sides, the apex being marked with oblique striole. The pygidium is black, longitudinally carinated down the middle with two oval convex yellow spots, striolated at the sides, the striole in the middle being transversely curved. The abdomen beneath is black and glossy ; it is convex, the second and third segments with a very slight longitudinal impression in the middle. The metasternum is marked with a large nearly cireular spot of yellow on each side (visible from above), and the third and fourth segments have a yellow spot on each side also seen from above. The terminal pair of spiracles of the abdomen are conically elevated. The specimen figured in the plate was kindly forwarded to me by M. Boheman from Stockholm, where I have also since examined other individuals. Species 7 (9)—MACROMA LUTESCENS. Puate VII, Fie. 2.

The clypeus is convex, very slightly angulated, and elevated in the middle of the fore margin. The maxille (fig. 6a) have the galea very acute and curved, and the basal lobe is produced at its apex into an acute spine, with another nearly as large in the middle of the inner edge; the mentum (fig. 64) is oblong, rounded at the anterior angles, and but very slightly emarginate in front. The yellow colour of the clypeus extends in a triangle nearly to the back of the head, which is nearly smooth. The yellow margin of the prothorax is angu- lated near the hinder angles; the dise is sparingly impressed with very fine punctures, as are also the elytra, where they scarcely form longitudinal lines. The black lateral margin of the elytra extends from the shoulders to rather beyond the middle, where it suddenly terminates, the yellow then extending to the margin. The black apex of the elytra is separated from the yellow portion by a strong elevated arched ridge, beyond which the apex is closely covered with delicate transverse striole, with which also the tricarinated pygidium is also covered. The black suture of the elytra is but little depressed at the base, and is slightly raised at the extremity. With the exception of the exposed sides of the metasternum and posterior cox, the under side of the body is black. In the large size of the tooth in the middle of the inner margin of the basal portion of the maxillz (mando), this species is distinguished from the majority of the genus, but agrees with Faldermann’s I. mirabilis. The very slight emargination of the mentum is also a peculiar character. The fulvous colour of the dise of the elytra occasionally assumes a rich more chestnut tint. C2 12 Orper—COLEOPTERA.

The posterior margin of the pronotum is nearly straight, being only very slightly produced over the base of the scutellum. I have given my reason for adopting Dr. Schaum’s name for this species in preference to Mr. Hope’s in my observations on M. nigripennis, Schaum, next described. The British Museum possesses a series of this species from various localities, viz. from Siam, Burmah, Cambogia, Dacca and China, all having a yellow scutellum—the Chinese specimens having two yellow spots on the back of the head, whilst others from Siam, India, and Burmah have the scutellum either entirely black or yellow at the base.

The specimen represented in the accompanying figure (pl. VI, fig. 7) is from Laas, Camboja, in the Collection of Count Mniszech. It is 7 lines long and 4 broad across the shoulders of the elytra. The underside of the head is pitchy. The anterior cox are pale yellow. The mentum is strongly angulated in the middle; the anterior part broadly ovate (fig. 7 a, the underside of the front of the head seen in front, concealing the base of the mentum). The front of the mesosternum is fulvous in the middle. The third and fourth segments of the abdomen are san- euineous at the sides and in the middle beneath. The whole of the abdomen is glossy and very delicately transversely striated, as are also the 4 broad black hind femora. The basal segments of the abdomen have an oblong impression in the unique male specimen which I have examined. The yellow sides of the metasternum are impunctate and very glossy. The scutellum is impunctate except at the base. The apex of the elytra is finely transversely striated, this part being separated from the dise by a sharp curved depression. The pygidium is black, with a strong central carina and two conical tubercles. The name of I, nigripennis was applied by Dr. Schaum and Mr. Hope to two different insects, the deserip- tions of which were published in the same year—1841. In such cases I think it is preferable to adopt that given by a monographer rather than that of a describer of isolated species, and therefore I retain Dr. Schaum’s name in preference to Mr. Hope’s, although the description given by the latter was read at the Entomological Society of London on the Ist of July, 1839.

My figure and the following notes are made from M. Gory’s typical specimens communicated by the late Dr. Schaum. The head beneath, with the maxilla and palpi, are dark luteous, the mentum yellow; the hind part of the head is dark brown; the coxe of the fore legs yellow; the deflexed anterior angles of the pronotum have a black border ; the front of the mesosternum is flat, perpendicular, and fulvous; the posterior angles of the epimera are deflexed and yellow coloured ; the third and fourth segments of the abdomen are dark blood red ; the second and fifth have a small ferruginous patch in the middle of each. The male has the three basal segments of the abdomen marked with an oval longitudinal impression. The pygidium is black, with a raised tricuspidate space, having a sharp longitudinal central carina. There is a variety of this species in the British Museum, collected in India by Colonel Whithill, nearly 9 lines long, black, with the lateral margins of the pronotum yellow, with a black spot ; the head and anterior cox yellow; the exposed part of the posterior coxie pale yellow; the abdomen black, with a red central vitta, and the middle segments with a blood-red spot on each side. Species 13 (15)—MACROMA MACULICOLLIS. PuatE VI, Fie. 10.

Westw. MS; Schaum, Verz. Lam. Melit. p. 60. The antennz are chestnut, with the club fulvous. The under side of the head is black; the mentum is yellow, strongly angulated in the middle, the anterior portion being obliquely truncate and broadly ovate in form. The disc of the pronotum is nearly smooth, but the sides are rather thickly punctate; the anterior and posterior margins are narrowly black, and on each side of the middle is a black longitudinal mark, the anterior half narrow, but forming a lozenge-shaped spot united behind to a large nearly rounded spot: there is also a small round spot in front of the middle of each side. The dise of the elytra is sparingly punctate, but the sides more thickly, the punctures being more transverse. The apex of each elytron is finely transversely punctate- striate, being separated from the dise by a sharply defined curved impression. The terminal hook of the max- ille is very acute, slender, and arched, the teeth of the inner lobe being short and robust. The mesosternum forms a nearly globose tubercle slightly advanced between the base of the middle legs. The abdomen in the male has the basal segments longitudinally impressed. 14 OrpeEr—COLEOPTERA. Sectlon—PENTAMERA. A specimen from Pachbon, Siam, collected by M. Mouhot, in the Museum of W. W. Saunders, Esq., F.R.S., agrees entirely with my type specimens from Upper India. Another specimen in the same Museum, collected also by M. Mouhot at Laas, differs only in having the dise of the pronotum entirely black, with the yellow lateral margin much narrowed behind the small black spot which is united to the dark dise of the pronotum.

Late ovata, glaberrima, nigra, clypeo rotundato margine antico parum reflexo, capite et pronoto sanguineis, hoe maculis 9 parvis rotundis nigris, pronoti basi elytrisque in medio basi depressis, humeris elevatis, sutura pone medium elevata, parte apicali elytrorum transverse striolata et e disco spatio elevato 4-dentato in singulo sepa- rata, pygidio tricarinato. Long. corp. lin. 114; lat. humer. elytr. lin. 63. Habitat ; Siam (Mouhot). In Mus. W. W. Saunders. Sumatra (Mohnike). This very striking species is at once distinguished by its great width. It is convex, but with the base of the pronotum and the scutellar region of the elytra considerably depressed in the centre. The head is convex, very delicately granulose ; the clypeus rounded in front, with the fore margin slightly elevated ; there is a slight round impression on each side near the base of the antenne, and a fine impressed line extends backwards from the same point. The upper side of the head is blood red, but beneath and at the sides behind the eyes it is black ; the antenne have the club chestnut coloured; the pronotum is very glossy, nearly impunctate on the dise, with the sides finely but sparingly punctured. The hind margin is considerably produced over the base of the scutellum. On the dise are nine small black round spots, four on each side, forming an oblique lozenge, and one in the centre behind the middle. The elytra are very glossy, the dise nearly impunctate, the shoulders Famity—CETONUD A. Sup-Famity—CREMASTOCHEILIDES. 15 are very broad and raised, the suture near the scutellum is depressed, but beyond the middle it is elevated into aridge. The terminal part of each elytron is thickly covered with very fine transverse striole, this part being separated from the dise by a curious ridge, which is scalloped into four teeth. The pygidium is tricarinated, the central carina arising at the base and not reaching the extremity, the two lateral ones arising towards the middle, and forming two terminal teeth. The body beneath is black and glossy, and in the only specimen which I have seen the basal segments are convex. The prothorax is subtriangular, with the posterior angles rounded; the breadth of this part equals the length from the front of the clypeus to the base of the scutel- lum. The breadth of the shoulders of the elytra equals their entire length, including that of the scutellum. The maxille (fig. 1@) have the apical lobe strong and sickle-shaped ; the inner lobe has the terminal tooth slightly bifid, and there is also a slender spine or spine-like bristle in the middle of the inner edge of this part of the maxille. The mentum is oblong (fig. 14), widest at the place of insertion of the palpi, the anterior part obliquely truncate, and the apex subemarginate. Species 17 (19).—MACROMA TRIGUTTULATA. Mohnike.

I consider the reasons given by Schaum for the rejection of Mr. Kirby’s generic name insufficient. The Lepidopterous name Cymatophora is sufficiently distinct from Mr. Kirby’s, and it occurs in a different order of insects. The rejection of a generic name in one order or class, because it is already employed in another, would, in the present state of science, involve the change of hundreds of names well known and generally adopted. The species of this genus are of small size, with the middle of the dise of each elytron raised, forming a polished costa, between which and the suture are several fine strixv. The elytra are also generally marked with small white silky spots. The species appear to be confined to Africa. Specres 1 (21)—CYMOPHORUS HILARIS. Pratt VIII, Fre. 10.

This pretty species is distinguished not only by its orange-coloured elytra, with a broad irregular black sutural mark, but also by the hind part of the prothorax not being narrowed at the shoulders. The clypeus has the sides, and especially the front margin, elevated ; the head and pronotum are finely punctured ; the sides of the elytra strongly punctured; the humeral and discoidal impressions of the latter are striolated; the disc glossy and finely but distantly punctured. The body beneath is shining; the sides of the metasternum strigosely punctured ; the abdomen blood red and glossy, with an oval central impression extending over the second, third, and basal half of the fourth segments. The maxillie have the galea acute and slightly curved, and the mando armed with two nearly equal acute teeth. The mentum is oblong, nearly straight along the fore edge, behind which it is obliquely truncated, so that the anterior part, seen laterally, is outwardly angulated. The anterior tibis in the female are slightly notched below the apex (fig. 10) rather than bidentate. The anterior process of the metasternum is thickened between the middle feet, and porrected towards the hind part of the prosternum. Species 2 (22)—CYMOPHORUS FLUCTIGER. Piatt VIII, Fie. 6.

This handsome species is at once known by the large pearly spots on the elytra, of which the anterior is the largest; the posterior lateral ones are sometimes connected with the two at the extremity of the suture, and the pygidium is marked with two small similar spots. The maxille (fig. 5) have a strong slightly curved acutely tipped galea, and two teeth at the extremity of the mando; the mentum is oblong, very setose on its outer surface, and angulated between the base of the labial palpi (fig. 5 4, seen from beneath ; 5c, seen laterally). The anterior tibia are entire in the male, in which sex the base of the abdomen beneath has a strong impres- sion. The prosternum forms a strong deflexed spine ; the metasternum is broad and porrected between the middle legs, but not forming a porrected point with the mesosternum, being squared off when seen laterally. The middle and hind femora have a thick row of grey hairs on the under margin; the body beneath is glossy- black, with grey hairs scattered about, a large patch on each side of the metasternum, the exposed part of the epimera, as well as a small patch on each of the metasternal epimerw, formed of thick grey pile; the sides of the abdominal segments are marked with fine curved lines, forming semioval punctures chiefly arranged in double rows.

The type of this genus agrees with Cymophorus in the form of its maxille and mentum, but the large size of the prothorax, and the peculiar style of sculpturing of the rugose elytra, distinguish it from all the species of that genus.

The head is simple, slightly convex, with the fore margin nearly straight and elevated. The disc is thickly punctured. The under side of the body is variegated with whitish scales. The pygidium is slightly carinated down the centre with two patches of luteous scales. The scutellum and base of the elytra are rugose with very short curved striole, mostly oblique and irregular; the dise of the elytra being densely covered with irregular punctures, and without the strongly raised curved costa observed in all the species of Cymophorus. The prothorax is nearly equal in breadth with the elytra, the hind part of the lateral margins being nearly parallel, the anterior portion becoming narrower towards the head; the sculpturing of this part of the body is peculiar. The analysis of the genus, which I made at the request: of my friend Burmeister in 1842 (see Handb. d. Ent. iii. p. 649), is described in the generic character given above. The Hopeian specimen still remains unique. Grenus—PRAONA. Westw. Gen. Nov. Corpus supra velutinum. Caput mediocre clypeo integro, tenue marginato. Antenne articulo basali haud dilatato.

The original type of this species, formerly in Gory’s Collection, still, I believe, continues unique ; the parts of the mouth have been dissected away, so that both Burmeister (Handb. d. Ent. iii. p. 658) and myself are unable absolutely to determine its affinity to the type of the Genus, H. fu/igineus. The anterior margin of the clypeus is very slightly angulated in the middle. The sides of the pronotum are deflexed and longitudinally striated. The prosternal spine before the anterior coxw is so deflexed as to be scarcely visible (« ganz niedrig’, mit borstiger spitze.’ Burm.) The metasternal process between the middle feet is not porrected, but advanced to a point, received within the notched extremity of the mesosternum (fig. 7a). The lateral margins of the elytra are transversely rugulose, and the four basal segments of the abdomen are longitudinally impressed down the centre. The hind legs are wanting in the type specimen.

This robust, dull black insect has the head very broad (fig. 82, seen beneath; 84, seen sideways), with the fore margin slightly reflexed. The basal joint of the antenne is very large and triangular, the second joint being inserted near the middle of its under surface. The mandibles (fig. 8 ¢) are very broad, the inner basal angle being much produced internally. The maxille have the two lobes produced into very sharp and slender teeth (fig. 8d). The mentum is very broad, strongly angulated below the middle (as seen in fig. 84). The labium has two setose lobes applied to the inner surface of the base of the mentum, and the labial palpi arise far apart, near the lateral margins of the mentum (fig. 8c). The prosternum is armed with a short slightly deflexed spine in front of the anterior coxe (fig. 84), and the mesosternal process is very short, flat, and acuminated behind, meeting the advanced point of the centre of the front of the mesosternum (fig. 8/). The body beneath is black and glossy ; the sides of the metasternum marked with small oblique striole; the abdomen beneath is convex; the pygidium convex, with a very slight central, oblong, scarcely raised tubercle; the segments finely but distantly punctured.

The remarkable and unique insect, which forms the type of this genus in its robust form and teeth of the maxillx, approaches Oplostomus, from which the armature of the head and prothorax, the shape of the mentum, and the tridentate anterior tibiae at once remove it; in several of the latter characters it approaches Cyclidius.

This is a shorter and more compact species than the European ones. The antenne are very short and 12- jointed (fig. 10a); the second recurrent vein of the fore wings forms a continuous line with the vein between the second and third submarginal cell; the mandibles are marked with a large white spot in front; the breadth of the thorax at the base of the fore wings is nearly equal to one-third of the length of the thorax and abdomen, and the length of the fore wings is equal to that of the thorax and three-fourths of the abdomen. The vein between the two marginal cells is received by the front of the second submarginal cell a short distance before its extremity, and the vein between the second and third submarginal cells is continuous with the second recurrent vein.

The subapical joint of the abdomen has a white fascia, interrupted in the middle, and the apical joint is white. The vein between the two marginal cells is obliqne, so that it extends into the third submarginal cell on its fore edge, whilst its hind edge receives the second recur- rent vein at one-third of its length from its base. The second submarginal cell is shorter than in Y. orientalis, so that the vein which closes its apex is nearer the base of the wing than the oblique vein between the two marginal cells and the second recurrent vein. * X. rufipes.

The unique male of this species in our Collection is closely allied to the male of Sirex spectrum, which forms a second section in the genus in Dr. Klug’s monograph, intermediate between the genuine Sirices and Tremex, differing from each in the number of joints in its maxillary and labial palpi. Its general characters agree, how- ever, so entirely with those of Sirex (except in the greatly elongated ovipositor), that it does not appear desirable to separate it subgenerically from the rest. The head is convex and sloping, with a central and two lateral impressions in the hinder part. The thorax is coarsely granulated, the collar quadrate and transversely grooved, the lateral margins denticulated. The abdominal segments have the basal portion of each depressed, leaving the sides and hinder margins somewhat raised ; the terminal segment is obconical, slightly serrated at the sides, and terminated in a small point. The wings are hyaline, and almost colourless; the large second submarginal cell is pedunculated at its base (as it is also in S. spectrum); the vein forming the hind margin of the long basal subcostal cell does not emit a small branch near its extremity. The legs are black, with the femora entirely red, the hinder pair being more pitchy on the upper part. Grenus—TREMEX (Jurine) XYLOTERUS. Hartig!. TREMEX PANDORA. Puate XXI, Fic. 9.

Head and prothorax zeneous black ; head convex, with small but deep punctures; collar rugose, with small conical tubercles; on the mesothorax these tubercles are fine. The metathorax is brownish black, smooth, the hind part with a luteous band divided by a brown central longitudinal line; the abdominal segments are rich purple, chalybeous on the hind margin, very slightly punctured except the terminal joints, which are rugose ; the basal segments have a luteous spot on each side, extending nearly the whole length of each joint. The four fore legs are luteous, the tip of the first and the remaining joints of the tarsi pitchy brown; the two hind legs are black, compressed, the femora fulvous, the basal joint of the tarsus broad. The wings are rich brown, with the veins darker brown, strongly glossed with pinkish purple; the body beneath is black, with the thoracic portions eneous. The antenne are as long as the head and anterior half of the metathorax: they are 20-jointed, and the first jot is pitchy, the second and third steel-green, polished, the fourth and following dark purplish-black, and compressed. The length of the fore wing equals that from the front of the head to the middle of the fifth seement of the abdomen. This insect is nearly related to several other species of the genus from the Eastern Islands, of which the following are the characters :— TREMEX INSIGNIS. Smith, Proc. Linn.

Batesianus (inhabiting also the same locality on the Amazon River) that it may possibly ultimately prove to be a variety thereof; the colour, however, of the body, and especially of the wings and stigma, seem to indicate it as specifically distinct. The face has two curved raised lines extending from the lower edge of the eyes towards the middle of the face, where they are united by a slender transverse carina, behind which are two rows of tubercles. The thorax is black, with a slender central slightly raised, and polished longitudinal line. The basal segment of the abdomen has a fine row of short striole at the base, the remainder being strongly punctured with a central raised line; the third, fourth, and fifth segments are marked on each side with a small whitish spot. The legs are thick and black, the two posterior femora red, the hind tibiz externally serrated. The fore wings have a broad fascia before, and another beyond the middle, the base being hyaline with two small oblong dark dots; the veins in the central hyaline part of the wing are colourless, and the stigma is fulvous.

The legs are robust and pitchy black, the extremity of the tibie and the tarsi being more pitehy. The wings are hyaline, the fore wings with an abbre- viated fascia before the middle of the wing, terminating in an oval spot in the middle of the dise; and beyond the middle of the wing is a broad brown fascia.

Head subglobose, vertex swollen or convex ; eyes lateral, large, ovate ; ocelli prominent, placed in a triangle between the eyes; antenn# setaceous, composed of 23-26 joints, the scape short, curved, slightly thickened towards the apex; the first joint of the flagellum half the length of the scape, the second as long as the scape, third and four following joints as lone as the first, the remaining joints are each in succession shorter than the preceding. Thorax as wide as the head, oblong, the sides parallel; the prothorax narrowed anteriorly into a short neck; the mesothorax slightly elevated in front; the scutellum elevated; the metathorax with a deep incision in the middle; the anterior wings with one or two marginal and four submarginal cells, the marginal cell, or cells, elongated, with a short appendix at the apex ; the first submarginal cell small, the second oblong, widest at the apex, the third subquadrate, the fourth extending to the apex of the wing: the second and third cells each receive a recurrent vein a little within their base; legs slender, not compressed; the four hind tibie bispinose at their apex; ungues with a strong broad tooth at the base; abdomen cylindrical, about twice the length of the head and thorax; the ovipositor short, and slightly exserted. This genus is evidently identical with Brachyxiphus of Philippi (Stettiner Entom. Zeit. 32 Jahre. 1871, p- 285, pl. III), although there are several characters given by that author which differ from those which I have observed. The maxillary palpi are described as 6-jointed, the first four joints of equal length, and the last shorter. They are, however, figured as only 5-jointed, with the first to the fourth of equal length, and the fifth shorter and oval (see his fig. 14). The labial palpi are described as 4-jointed, the third joint the shortest and the last egg-shaped (see his fig. 1c). Of the sexes he observes—‘ Mannchen habe ich nicht gesehen.’ His figures of his two species evidently, however, represent both sexes, figure 1 being a female, and figure 2 a male. He also notices the difference in the number of marginal (radial) cells in the individuals constituting his two species, described as follows :— 1. Brachyxiphus grandis Ph. (fig. 1), niger, abdominis seementis 3-8 aurantiacis; antennis 26-articulatis ; alis nigricantibus cellulis radialibus duabus. Long. corp. 104 lin.; exp. alar. 19 lin. Hab. Valdivia. 2.

Hab. Valdivia. From this deseription, and the accompanying figures, it would appear that the specimen represented in his fig. 2, having all the appearance of a male, has only one radial (or marginal) cell; whilst his fig. 1, represented with a short ovipositor, as a female, has two radial cells: thus differing from the specimens represented in my plates, in which the male has two radial cells and the female only one. In this uncertainty, I hesitate in uniting the male insect, from Chili, represented in my plate XXIII, fig. 1, having two radial cells, with Philippr’s female, fig. 1, from Valdivia, which has also two radial cells, although agreeing with it in colours.

We are indebted to Mr. Smith for a note on the habits of this species, In a nest of Polistes Lanio Fabr., from St. Salvador, in the British Museum, he found a specimen of the Trigonalys with its head protruding out of one of the cells. The parasite was not enveloped in any pellicle, nor had the cell been closed in any way ; the wings were crumpled up at the sides of the body, as is usual in Hymenopterous insects which have not expanded them, proving very satisfactorily that it had never quitted the cell, and that Trigonalys is the parasite of Polistes. ‘The discovery,’ Mr. Smith adds, ‘is one of much interest, proving the relationship of the insect to be amongst the Pupivora, to which family it had been previously assigned by Mr. Westwood.’ (Proc.

This Genus comprises a considerable number of interesting insects, in which not only various peculiarities of structure exist, but considerable variation occurs in some of their characters on which it has been usual, amongst Hymenopterous insects, to establish genera. Thus the penultimate joint of the tarsi is obliquely dilated in a remarkable manner, with the terminal joint set on close to the base of the preceding; in the hind legs the tarsi vary in the number of their joints in the opposite sexes, and this character (having been supposed to be a sectional instead of a sexual one) has led to the establishment of a separate genus, Megischus, for the females of some of the species. The veins also in the discoidal part of the wing are more or less obsolete in some of the smaller species, and this circumstance led Mr, F. Smith to propose the formation of another genus, Feenatopus, in the Journal of Proceedings of the Linnean Society (Suppl. Zool. 1860, p. 58), to which also the MS. name of Stenophasmus was applied by the same gentleman in the British Museum Collection. Tf it should be thought advisable to establish genera or subgenera in this group on account of the more or less obsolete character of these veins, a greater number of groups must be proposed, as each modification would require separation.

In the figure of the male of this insect (fig. 8) the peduncle of the abdomen is represented too long: rela- tively to the abdomen by the length of one line. The head has three small transverse tubercles between the front of the eyes; the mandibles (fig. 8a, seen from above) are, when seen laterally, obliquely truncate at the tips; the maxille are minute, with two membranaceous lobes. The maxillary palpi are very long and pen- dulous, with the three terminal joints very long (fig. 84); the labium is somewhat heart-shaped (fig. 8c) and finely setose, with the front margin straight, and with a lobe on each side at the base, arising from an obconical mentum. The labial palpi are rather robust and four-jointed. The difference in the number of joints of the 128 Orper—HYMENOPTERA. hind tarsi in the opposite sexes (fig. 8d, male; fig. 8¢, female), is noticed in the specific character given above. The tarsal ungues have a small tooth at the base, and there is a small heart-shaped pulvillus between them, This is, I believe, the first species of this curious group, described as an inhabitant of the continent of Africa, thus proving, in conjunction with the Australian insect represented in fig. 2, that the genus is dis- tributed over all the four quarters of the globe, species from Europe, Asia, and America having previously been described. 8.

Syy.: Sibyllina. Westw. Trans. Ent. Soc. Lond. 1868, part iv. December, p. 329. This curious genus was considered (doubtingly) by the late Mr. Haliday (one of the most profound Hymenopterologists) as one of the Sphegidw, with smooth legs, near Pelopzeus, as appears by a note attached to a specimen of the type in the Collection of the British Museum}, On exhibiting a specimen of this insect at a meeting of the Entomological Society, I expressed an opinion of its relations embodied in the following passage, subsequently published in the Transactions of the Society :— ‘Genus novum Aculeatorum, quoad affinitates animum excrucians, sed ad familiam Vespidarum ut mihi videtur magis approximans. Corpus elongatum, Belonogastri (Vespidarum) vel Pelopzi (Sphegidarum) habitu, etiam Formicarum nonnullarum antennis elongatis, non dissimile.’ Mr. F. Smith, on the same occasion, also considered that ‘it had more characters in accordance with those of the ants than with any other family.’ (Proc. Ent. Soc. Nov. 16, 1868.) Mr. Cresson, who first described this genus, placed it undoubtingly amongst the multitudinous genera of Ichneumonidze (which caused me to overlook it), remarking, ‘I am at present unable to define the true position of this remarkable genus. It seems to form a connecting link between the [chneumones genuini and the Adseiti ; from the former it differs by the paucity of the antennal joints, and from the latter, by the anterior wings having a faint indication of a second recurrent nervure. Its structure places it, beyond doubt, in the family Ichneumonide, whilst its general appearance, together with the arrangement of the wing-veins, seems to place it among the Adsciti, where I will allow it to remain, for the present.’ Subsequently, Mr. Smith (without being aware that the insect had been thus commented upon by Ir. Cresson), in a paper communicated to the Entomological Society on the 4th Jan. 1869 (Trans. 1868, Proc. li.) discussed the affinities of this genus at length with great acumen, contending, ‘1st, That all wasps have ‘* Antenne foem. not geniculate; hind wings incised at end of the pobrachial vein; fore wings with a third discal areole. See also form of thorax. I think a Sphegid, with smooth legs, near Pelopeus.’ (Haliday MS. in Brit. Mus.) Famity—EVANIID. 131 the wings folded, whilst they are flat in Rhopalosoma. 2nd, Rhopalosoma has only two submarginal cells, whilst every known wasp has either three or four. 3rd, Every true wasp has three discoidal cells in the fore wings, whilst Rhopalosoma has only one. 4th, The prothorax [collar] in all Vespidw extends backwards to the tegulie, which is not the case in Rhopalosoma. 5th, Lunate eyes (which Rhopalosoma possesses) are found in Mutilla, Scolia, Sapyga, Pemphredon, and Philanthus amongst the Aculeata, and in the Ichneumonideous genera Pimpla, Campoplex, Anomalon, Ophion, and some others. 6th, The tarsal ungues (toothed in Rhopalo- soma) are simple in the social Vespide, although dentate in the solitary wasps.’ On the other hand, Mr. Smith regarded the insect as belonging to the Ichneumonides. ‘7th, Because, amongst the minute [Adscitous] groups, species exist having only 12-jointed antennw (Ephidrus), and others having 13-jointed antenne (Trioxys).’ 8th, Mr. Smith states ‘that in Rhopalosoma a distinct second joint in the trochanters is quite as visible as in the Ichneumonideous genus Metopius. 9th, The antennex of every known species of wasp are geniculate, which is not the case in Rhopalosoma. 10th, The prothorax of Rhopalosoma is of the same structure as in Ophion and Anomalon. 11th, The ocelli are large and prominent in Rhopalosoma, as in the two last-named genera ; in the Vespide they are much smaller, and usually more sunken than prominent. 12th, The broadly dilated tarsi in Rhopalosoma do not occur in Vespidie, but are peculiarly characteristic of Anomalon, 13th, The basal seg- ment of the abdomen of Rhopalosoma is narrowed into a petiole, as in Ophion and Anomalon. 14th, The sting of Rhopalosoma agrees with that of Ophion and Anomalon, as well as Belonogaster and Vespa.’ Although thus pointing out the relationship of the genus with Ophion and Anomalon, Mr. Smith admitted its want of ‘strong affinity with any other known insect.’ To these objections I have to reply as follows :— . Some of the most aberrant wasp genera, and the remainder of the Aculeata, have flat wings. ore . Rhopalosoma has three submarginal cells. In all the genuine Ichneumons, the first submarginal and the anterior discoidal cells are thrown together. Even in those Adsciti which have three distinct sub- marginal cells, the first (and only) recurrent vein enters the first submarginal cell, and not the second, as in Rhopalosoma. 3. Rhopalosoma has three discoidal cells, the lower outer one having its extremity partially closed by a transverse nearly obsolete vein. 4, The collar of Rhopalosoma extends back laterally to the tegule, although not seen dorsally at the sides of the thorax. 5. The eyes of Rhopalosoma are not lunate, but oval, with a small emargination in the middle of the inner margin. 6. The ungues in Rhopalosoma are furnished beneath with two obtuse spines. 7. No species of Adscitous Ichneumon, nor indeed any other terebrant Hymenopterous insect, is known possessing 13-jointed antenn in the males and 12-jointed in the females. This is one of the leading characters of the Aculeata. 8. I cannot discover a second joint in the trochanters of Rhopalosoma. Its existence is one of the leading characters of the terebrant Hymenoptera. In certain positions, a faint appearance of an articulation near the base of the femora may be observed. In the Ichneumons the two joints of the trochanters are distinct, and nearly equal in size in many species. 9. The long, straight, filiform structure of the antenne of Rhopalosoma is unquestionably a strong character against its belonging to the Vespidi. 10. The front of the thorax of Rhopalosoma is similarly formed to that of Ophion. 11. The ocelli of Rhopalosoma agree with those of Ophion. 12. I know no Ichneumonideous nor indeed any other Hymenopterous insect with feet like those of the female - Rhopalosoma, whereas they are simple in the male. 13. The pedunculated basal segment of the abdomen of Rhopalosoma occurs in many groups of Aculeata, as well as in many of the Terebrantia. 14. The sting of Rhopalosoma is a genuine aculeus, with a broad sheath. 15. The lobed base of the hind wing, and the 6-jointed maxillary palpi, which latter character occurs in no genuine Ichneumon, must not be overlooked in determining the relations of the genus. From the preceding discussion it will doubtless be considered that, whilst in several important respects the insect before us agrees with some of the Ichneumonide, it is, in others equally important, allied to the Aculeata, forming by itself a most exceptional and isolated section. $2 132 Orprer—HYMENOPTERA.

Mr. Walker considers that ‘ this genus belongs to the Torymide, and is most nearly allied to Megastigmus, but it has also a tendency to the structure of the Leucospidw, and shews the transition between these two families ’"—a position I am not inclined to adopt, failing to observe any relationship with Leucospis. The mandibles are strong and armed with three teeth, as in pl. XXV, fig. 10a, the inner part representing the fourth tooth being broader and obtuse. The British Museum specimen has the terminal joints of the antenne broken off, the second joint of the antenne very small, and the third minute and annular, the fourth and following much longer than the second, and setose.

It agrees with the Chaleidites in the structure of the wing veins, and may be considered as the type of a new family of that tribe.’ Except in having the abdomen compressed and the scutellum slightly bidentate (characters found in many other Chalcidide), I can perceive no relationship with the Cynipide.

The type C. cornigera, Westw. (Op. cit. and Stephen’s Illustr. Brit. Ent. Mand. pl. XLV, fig. 1; Epimacrus rufus, Walker, Ent. Mag. i. p. 149), was taken by Mr. R. Lewis on trunks of trees in St. James’s Park, London, in the Spring of 1882. iL also took it on palings on Wandsworth Common in July, 1835. Mr. Stephens took it near Ripley, and Mr. Doubleday near Epping. The males vary in their size as well as in the amount of development of the frontal horns. Sus-Fammy—PERILAMPIDES. Grnus—PHILOMIDES.

XX VI, fig. 14). The mandibles are acute and sickle-shaped, with a tooth on the inner margin towards the middle. The maxillz are terminated by an elongated lobe armed with strong bristles on its outer edge (fig. 1¢); the maxillary palpi are very short and apparently 4-jointed, the basal joint very short, the second the largest, angulated in the middle of the inner margin and bristly ; the two terminal joints minute. The labium is ovate, with two short 2-jointed palpi, strongly setose (fig. 1 d@). The tarsal ungues are denticulated on their inner edge (fig. 1 e). The specimen of this species now in the Museum of the Jardin des Plantes, Paris (Coll. Sichel), has the club of the antenne more slender, and the yellow lateral spots of the scutellum are united by a pale band across its base. PHILOMIDES PAPHIUS.

The head and collar of this very beautiful insect are green, finely punctured; the mesonotum is green, with a large coppery-purple spot in front, and a larger one between the parapsides, the sides of which are tinged with the same coppery-purple, which is also the colour of the large scutellum, which is marked with two oval green spots. The abdomen is chalybeous, very glossy, and varied with green and coppery-red and orange, of which colours are two large spots on the fifth and sixth segments of the abdomen; the sixth segment has a large spiracle near each of the anterior lateral angles. The antenne (fig. 6a) have the basal joint long, the second moderately long and slender, the third and following gradually becoming shorter and somewhat broader, the last (eleventh joint) being the shortest and truncate at the tip, the apex being furnished with a small spur or spine on its under side. The hind femora are large and clavate, armed on the under side with eleven teeth, of which the middle ones are the largest. The curved tibie are received into a groove on the under side of the thighs, the inner edge of which groove is furnished with a row of eight small tubercles (fig. 6 4). Sprcires 2—POLYCHROMA REGALIS.

The twenty-eighth Plate of this work is devoted to a series of remarkable insects belonging to the family Chalcididw, closely allied to the Eurytomides, but in general distinguished by the great, and often abnormal development of the hinder parts of the thorax, and often also by the strongly pectinated antenne of the males. The typical genus is Eucharis of Fabricius, but several others have been separated, including Thoracantha Latr., Stilbula Spinola, Schizaspidia Westw., and Gallaria Brullé; (Psilogaster Blanchard is identical with Stilbula). The generic distribution of the group is, however, at present unsettled, and can only be established upon a more careful investigation of the characters of the species than has hitherto been given to them; thus, in the typical species Zucharis adscendens, a native of Europe, and also introduced into the British list, I have been unable, after repeated dissections, to discover any normally formed maxillz or labium, the mouth bemg apparently closed by membrane ; the mandibles of this species are represented in pl. XXVIII, figs. 15¢2, 1563. Inthe insect figured under the name of Schizaspidia rudis (fig. 5), the mandibles are armed with strong teeth (fig. 5 4), and the maxill and labium, with their palpi (figs. 5c, 5), are well developed. The antenne vary in nearly every species, as may be observed on inspecting the twenty-eighth plate, in which I have added figures of the antenne of several species not represented; thus, fig. 15 ¢ represents the antenne of the male, and 15d, that of the female, of the type, Hucharis adscendens. Fig. 18 represents the 12-jointed antenna of the male of Hucharis Volusus (Entomologist, pl. P, fig. 1c); the intermediate joints being bifurcate, with the inner branch shorter than the outer. Fig. 14a represents the antenna, apparently 9-joimted, of the male, and 14c, that of the female, apparently 11-joited, of Hucharis Zalates (ibid. fig. 4.a, and fig. 44), in both of which the last apparent joint (or more probably only that of the male) is made up of the three ordinary terminal joints closely soldered together.

The mandibles of this species are very sickle-shaped (fig. 5 4), with two strong teeth on the inner edge, of which the second is truncated. The maxille (fig. 5c) are terminated by a long narrow membranous blade, which unite and form a tubular defence for the labium. The maxillary palpi are long, slender, 4-jointed, the last joint slightly clavate. The mentum (fig. 57) is slender and tubular, as is the labium, the labial palpi 2-jointed, the second joint slightly clavate. The front of the thorax is vertical and concave, forming a saucer- shaped space for the reception of the head. Fig. 5 ¢ represents the insect seen sideways, with the limbs removed.

Famity—PROCTOTRUPID (Steph.), OXYURA (Latr.) Sus-Famity—BETHYLLIDES (Haliday), GONATOPIDES, pars (Westw.) The three plates, XXIX, XXX, and XXXI, are devoted to the illustration of a very rare and curious group of Hymenoptera whose relations with other families are very peculiar. In many respects they approach nearly to the typical Aculeata, especially to the Mutillide, in the apterous condition of the females, certain of which closely resemble the females of Methoca; whilst others resemble some of the smaller Fossores allied to Psen, &e. Their 13-jointed antenne in both sexes, however, at once distinguish them and remove them to the great aberrant section of the Hymenoptera. Here they are related, on the one hand, to those genera of Proctotrupide, in which the fore wings have most of the apical veins in an undeveloped condition, although their situation is indicated by certain narrow markings on the wings destitute of the fine set with which the other parts of the wings are clothed. Some of the species, especially those of the Genus Mesitius, are closely allied to the Chrysidide (which have also 13-jointed antenne in both sexes, and partially obsolete veins in the fore wings); but Chrysis has only 5-jointed maxillary palpi, and the ovipositor is differently constructed. The Genus Bethylus Latr. (Omalus Jur.) has been restricted to the flat-headed species, which have the hind basal cell of the fore wings shorter than the front one, and which have 12-jointed antenne ; whereas in the species before us those organs are uniformly 18-jointed in both sexes. It is possible that some of the smaller continental species of Epyris may have been described by Dr. Klug in his Monograph on Bethylus, in which seven species of the genus are described, in Weber and Mohr’s Archiv. (vol. ii. p. 187—). In his generic characters, however, he describes and figures the maxillary palpi as 6-jointed, and the labial as 4-jointed; and he states that his species agree in their general characters with Ziphia villosa (S. Piez. 235), and Bethylus villosus (S. Piez. 236). The late lamented A. H. Haliday was engaged upon a Memoir on the European Species of the Group, whilst I was occupied, in conjunction with him, chiefly upon the extra species. My illustrations are therefore confined to the extra-European species (with the exception of our British species, including Pristocera depressa), and the species of Mesitius. It is to be hoped that his valuable materials will not be lost to science. The species are for the most part of small size, although the size of many of them considerably exceeds that of the great mass of the Proctotrupide, some of which indeed are the most minute of insects. Genus—CALYOZA. (Westw. Trans. Ent. Soc. Lond. vol. ii. p. 56.) Corpus elongatum subdepressum; caput magnum subeonvexum, oculi ante medium capitis lateraliter positi: ocelli postici; antenne in utroque sexu 13-articulate, articulis secundo et tertio minutis, 4-12 in mare ramum longum emittentibus, in foemina (fig. 2@) simplicibus cylindricis; mandibule elongate; in mare apice lato oblique truncato (fig. 12) dente magno apicali, alterisque tribus parvis obtusis, in fcemina (figs. 24, 2¢, e latere visa) magis irregulariter dentatis, dente interno obtuso subtus setis rigidis armato, dente medio apicali magno, trigono, alteris externis parvis obtusis; maxille (fig. 14, mas) parve, apice lobis tribus planis membranaceis ciliatis; palpi maxillares modice elongati 6-articulati, articulis 1 et 2 brevibus, reliquis 4 longioribus fere equalibus at sensim tenuioribus ; mentum (fig. 1c, mas; 2d, feemina) subobovatum ; palpis labialibus brevibus 3-articulatis ; collare magnum subtrigonum antice rotundatum ; metathorax longitudinaliter suleatum et trans- verse striolatum; ale antic tantum cellulis duabus basalibus, stigmate magno, cellulaque unica marginali incompleta instruct, ungues tarsorum acuti basi lati denteque medio armati (fig. 2 e). This genus was proposed by me for a male insect preserved in gum anime in the Collection of Mr. Strong, of Long Acre, London. Its characters were consequently not satisfactorily examined. I have recently obtained a male insect from Port Natal, collected by Herr Gueinzius, which I have no hesitation in giving as identical with the Copal individual, and the British Museum Collection possesses a female which I am equally convinced is the other sex of the same species.

Mr. Haliday also kindly sent me a pair (but I am not acquainted with their locality). The Comte de Castelnau took it near Paris, and I have received it from the neighbourhood of Berlin, taken by Dr. Burmeister, from Stuttgart, taken by Van Roser, and near Brussels, from M. Wesmael, the latter under the name of Omalus fuscicornis Jurine, but that insect, as appears clearly from the figure of the fore wings, belongs to the flat- headed Genus Bethylus. The species was first described by Mr. Haliday, who mistook it for my F#. niger, which name he corrected subsequently to L. subcyaneus. I am obliged to alter the latter name from the fact that it is incorrect, the specimen described by Haliday having been washed over with gum water mixed with corrosive sublimate, which gave it an unnatural bloom. I have therefore applied to it the name of its lamented and most talented deseriber. Srecres 5—EPYRIS LATHROBIOIDES. Pratt XXIX, Fic. 7.

XX, figs. 1-3, and details (nec Ceraphron formicarius, Panz. Faun. Germ. fase. 97, tab. XVI. nee Omalus formicarius, Jurine, Hymenopt. Pp: 301). Having received specimens of this interesting little insect from M. Victor Audouin himself, I am able to point out its real generic position, and also to state its want of identity with the insect to which it was referred by its discoverer and others. In his plate he incorrectly represents the antennz as fourteen-jointed, but in his text he describes them correctly as thirteen-jointed, but as ‘coudées,’ which is not the case. In the spring of 1838, M. V. Audouin observed numbers of specimens running about very quickly on the young shoots of vines in the ‘Maconnais,’ which were already infested with the young larve of the destructive Zortrix (or Pyralis) Vitana, which were often seized and killed by the winged Goniozus. He subsequently, in the month of July, discovered the history of the parasite, having found a larva of the Zortriw covered with eight small apodal larve of a deli- eate green colour, and of the size of a large pin’s head; each of these little parasites had its head immersed between the segments of the body of the larva. M. Audouin has given very careful details of the structure and economy of these little parasite larve, which at the end of six days had completely changed both their form and colour ; the whole of the anterior part of their bodies had penetrated into the body of their victim, which had become much contracted, whilst they had assumed an oblong form and become brightish yellow in colour. In two days more they had become darker coloured with whitish spots, with a brown blotch at the extremity of their bodies. On the 2nd of August, all these larve, having quitted the shrivelled body of the caterpillar of the Tortria, commenced spinning a small cocoon of dirty-white silk, in the interior of which they were trans- formed to pupe. In a fortnight’s time the parasitic insects appeared in their perfect state. The cocoons are generally fixed to the leaves, being attached to each other by a brown layer of silk.

The characters of this genus, founded only on female specimens, were first detailed in my monograph of the group published in the second volume of the Transactions of the Entomological Society, with figures of the generic details!. Up to the present time no description of the male characters of the group has been published, but I am now able, by the researches of Mr. Haliday in Italy, and Sir S. 8. Saunders in Albania and Corfu, to complete the diagnosis of the genus. Corpus elongatum gracile leve, maris alatum, femina apterum; caput magnum subquadratum supra convexum, foemine oculis parvis, ocellis obsoletis ; antenne breviuscule in utroque sexu 18-articulate (fig. 13 a, 1 Tn the text of this memoir, vol. ii. p. 1-6, the antennz were inadvertently described as ‘ ro-articulate,’ instead of 13-jointed as they are in reality, and as shewn in my figures, pl. XV, fig. 10 a, representing both antenne of Sel. znter- media, and fig. 11 6, the antenna of Sel. contracta. Zz 170 Orprr—H YMENOPTERA. mas) in fcemina breviores et paullo crassiores, articulo primo longo, secundo tertio majori, hoc et reliquis parvis, ultimo ovali; mandibule parve apice obtuse 4-dentate (fig. 134, mas); maxille parve, apice lobis duobus ciliatis instruct ; palpi maxillares breves 5-articulati, articulis apicalibus tenuioribus (fig. 13 c); mentum anguste ovale ; palpi labiales 3-articulati; collare magnum trigonum vel semi-ovatum ; mesothorax segmentis coalitis scutelliformis; metathorax oblongus, in feemina basi paullo angustior; abdomen elongatum cylindricum apice in fceemina paullo attenuatum; pedes breves crassi; ale maris satis magne, antice cellulis duabus basalibus minutis tantum instructe, stigmate vix indicato, postice aveni. The thirteen-jointed antennz in both sexes indicates at once the relationship of Scleroderma to the pre- ceding genera, which is further shewn by the similarity of the females to that of Pristocera depressa (pl, XXX, fig. 4), whilst the five-jointed maxillary palpi, and the minute basal cells of the wings, at once distinguish it. There is a great similarity between the females and those of the Genus Methoca, but the latter have the normal number (twelve) of joints in the antenne of the typical aculeate Hymenoptera. There is a considerable number of species of this genus, as may be seen by my monograph above cited, and by the work of Nees ab Esenbeck, who has introduced several into his Genus Omalus. Mr. Thwaites has sent me a species from Ceylon, the female of which has wings. Mr. Haliday took three or four specimens of both sexes of a Scleroderma in a chamber in which Attagenus Pellio abounded in the mattresses stuffed with husks of Indian corn. He also once observed a swarm of little ant-like insects (which proved to be Scleroderme) between the sheets of a bed made upon a sofa in a house at Lucca, and he suggested the probability that the sofa was stuffed with hair or wool infested by the Attagenus Pellio. The Scleroderma bicolor of Smith, collected in Makassar by Mr. Wallace, is a species of this genus, but the Sel. modesta, Smith, brought from ‘ Mysol,’ by Mr. Wallace, belongs to the following Genus Apenesia. Sc/. contracta, Westw., Trans. Ent. Soe. vol. ii. p. 169, from Carolina, in the Royal Museum of Berlin, is most probably the female of Pristocera atra, or an allied species, SCLERODERMA SIDNEYANA.

The misshaped 4-jointed maxillary palpi, strong legs, and 18-jointed antenne distinguish the females of this genus from the wingless females of the allied genera, as well as from the similar aculeated genera.

The large size of the scales at the base of the wings, the minute size of the oral organs, the cornuted head and neck, and the obsolete character of the veins beyond the middle of the fore wings, give this singular insect a relationship to some of the Diapriides; whilst, in other respects, it seems to approach the Cynipide. The post costal vein of the fore wings at its apex does not touch the costa, but is deflexed into a branch running into the dise obliquely. 172 Orper—HYMENOPTERA., Species untca—LOBOSCELIDIA RUFESCENS.

XXX. fig. 3), but much larger, though with the spines much smaller; the tegmina and wings extend to the extremity of the second dorsal segment of the abdomen. The two anterior discoidal spines of the prothorax are smaller than the four posterior ones forming the posterior row, which are much more numerous and still smaller in /7. Grayii. The mesothorax has the square central dorsal part armed with three marginal spines on each side, three pairs of distant spines on its dise, and only two approximatory spines in the place of the posterior coronet of spines in ZH. Grayii; the teg- mina are comparatively larger, and extend to the extremity of the second abdominal segment. The sides of the body and the femora are much less strongly spined than in H. Grayii, but the tibial spines are very robust. The exposed portion of the dorsal piece of the ovipositor (fig. 1a, y) is elongate-lanceolate, narrow, gradu- ally pointed to the tip, where it is slightly furcate, and is half as long again as the terminal dorsal segment (*). Fig. 1a represents the four terminal segments of the body of the female lying on its back, with the parts of the ovipositor raised and separated, and fig. 1 4 the ventral surface of the ovipositor, the lettering of the different parts being the same in both figures; the * representing the ninth or terminal segment of the abdomen. a represents the large boat-shaped piece arising at the base of the seventh segment, and shutting in the other parts when at rest; 4, a pair of curved horny blades, each arising from a broad basal piece, ¢; d, two shorter horny bifid plates, which unite with 4 to form a concave bed for the reception of the larger eggs; e, the under lining of the basal part of the last segment ; f, a pair of straight horny conical appendages, at the base of each of which is seen a minute conical style; y, the under side of the upper portion of the sheath of the ovipositor, and + the entrance of the anus. I had named the specimen of this species, figured in plate XXXII, in memory of the late Rev. F. W. Hope, the munificent founder of the Chair of Zoology in the University of Oxford, to whom these curious insects were especial objects of interest, having never seen the original type of H. di/atata, the Hopeian specimen being in spirits and discoloured. The Saundersian Collection, however, now added to the Hopeian Museum by the liberality of Mrs. Hope, contains a dried specimen, and has enabled me to identify the species. 174 OrpErR—ORTHOPTERA. ; HETEROPTERYX CASTELNAUDII.

VIII, 1839, and ib. 4th Ser. vol. viii, 1868, p. 5), that the black butterfly with red and yellow spots, figured by him under the name of P. Duponchelii, was a female, and that a smaller and still darker coloured individual was the male, I was led to describe the female insect, here figured by me, as a distinct species in the Trans. Ent. Soe. London, as above referred to, with the suggestion that it might however ultimately be discovered that M. Lucas had mistaken the sex of his first specimen, and that it might be in reality the male of the insect now before us. I was led chiefly to this opinion by the analogy between the two insects and the two sexes of the Australian Hurycus Cressida, the males of which are black, with red and white markings, and the females semitransparent and more or less brown, with darker brown marks. Moreover the female of Huryades Corethrus (a species closely allied to the female insect here figured) possesses anal lobes similar to those of Par- nassius and Eurycus, as stated by Mr. E. Doubleday from information which I had communicated to him (Gen. Diurn. Lep. i. p. 21); and in certain females of the species here figured these anal lobes are greatly developed, and nearly as long as the whole abdomen: whereas in Mr. Druce’s specimen of the female here figured these lobes are either not yet fully developed, or have been broken off near the base. The correctness of my suppo- sition as to the mistakes of M. Lucas, and the sexual relationship between this female insect and the male P. Duponchelii of Lucas, has been fully determined by Dr. Burmeister (who, from his residence in Buenos Ayres, the locality of both Cz. Corethrus and Duponchelii, has had full opportunities of settling the question) in the Stettiner Entomolog. Zeit. 31 Jahrg. (1870), p. 414, as well as by M. A. Guénée in his ‘ Notice sur divers Lépidoptéres du Musée de Genéve,’ where the females of both these species are figured. Famity—N YMPHALIDA. 181 Famity—N YMPHALID. Grenus—CHARAXES.

The upper side of the fore wings is of a rich dark brown colour, the basal portion, especially along the costa, being of a rich dark chestnut, varied by a blackish patch at the extremity of the discoidal cell, which is thereby separated from two other rich chestnut spots placed obliquely, and two others, at a greater distance, placed transversely. From nearly the middle of the inner margin arises a broad buff-coloured fascia with sinuated edges, which soon breaks into oval detached spots of smaller size, extending nearly to the apex, the last spot of this series being small, subcostal, and placed nearer to the discoidal cell of the wing, the spots between the branches of the median vein are each composed as it were of two conjoined spots: near the apical margin is a row of small, nearly rounded, fulvous spots. The hind wings are dark brown, the middle occupied by a broad buff-coloured fascia with nearly regular edges ; the margin is broadly fulvous-red, with a very slender black marginal line. The two tails of each hind wing are rather long and slender. On the under side the ground colour of the wings is pale buff or straw coloured, marked with numerous rich fulvous-red patches. The discoidal cell in the fore wings is traversed by four of the latter, the third of which is very sinuous, followed by a short fulvous-red bar from the subcostal vein; the wing between the dis- coidal cell and the middle of the inner margin is of a purplish tinge, with several dark brown irregular trans- verse marks; half way between the middle of the wing and the apical margin is a row of slender fulvous- brown lunules, followed by a row of large oval-shaped fulvous-red spots, darkest next the margin, from which they are separated by reversed pale fleshy lunules; next the anal angle is a large compound black spot, with several patches of pale blue scales on its outer side. The hind wings have a nearly straight black line running across them near the middle, followed by a pale whitish-buff space; the space between the base of the wings and this line being marked by several irregular fulvous-red fascize, the outermost being the widest, and joining the black line, which is angulated close to the anal margin. The broad pale fascia is followed by a row of conjoined fulvous-red lunules, beyond which the wing is varied with alternate lunate bars of greenish buff, ful- vous-red, black, pinkish-grey, and fulvous; the anal angle having two blue-black dots edged above with white lunules. The body above is dark chestnut, with four white dots on the crown of the head; the palpi and under side of the chest are varied with white. Species 2—CHARAXES ANTICLEA 92. (Charaxes Cymo, Hope MS.)

The insect here represented was kindly sent to me from the Royal Dublin Society of Natural History for illustration in this work by Mr. W. F. Kirby (the indefatigable author of a most useful ‘Synonymic Catalogue of Diurnal Lepidoptera ’), by whom it was considered to be the female of J. Westermanni, of which specimens had been received with it from Cape Coast, Africa. It will be observed, however, that, in addition to other charac- ters, the middle of the hind wings wants the undulated markings of the male. ‘It differs strikingly from the male in the upper side. It is brown above, the base darker, the whole of the centre of the hind wings filled with a broad orange band (much duller than in the male) which extends to the adjacent portion of the fore wings, curving inwards across the cell, where it becomes much more obscure. The orange band of the hind wings seems to have been edged with lilac-blue, and there are traces of detached bright blue scales in the cell of the fore wings. There is a row of five black spots towards the edge of the orange on the hind wings (visible on the under side in the male also), and continued, in the female, on the fore wings, although the only conspicuous spot is one near the hinder angle of the fore wings. Beneath, the female chiefly differs in wanting nearly all the dark markings, and in the orange markings being more suffused and not sharply defined as in the male.’ Famity—HESPERIIDA. 183 Famity—HESPERUD.

The fore wings are chalybeous black, with seven spots of white: one close to the base on the hind margin ; three between the base and middle, of unequal size; two large ones near the middle, one of which is at the extremity of the discoidal cell, and one in the space between the first and second branches of the median vein. These are followed by a smaller one in the space between the second and third branches of the median vein ; and there is an oval 4-partite spot between the cell and the apex of the wing. The hind wings have a very narrow white transverse streak close to the base, the middle of the wing being occupied by a large white bar divided by the median and postcostal veins, and their branches (which are broadly black) into five portions, the broader outer margin of these wings being more strongly chalybeate than the base. The head and body are black, the head with a large white frontal spot, and two small ones between the eyes. The tippets of the collar or prothorax are clothed with scarlet hairs, the tegule or wing scales, together with a pair of dots in front of them, and a second pair behind them, at the sides of the disc, as well as the narrow hind margin of the scutellum, white: the latter is followed by a curved band of scarlet, the extremity of the abdomen being of the same colour: the four middle segments of the abdomen are luteous, with a narrow dark longitudinal line down the centre. The palpi are broadly truneate, being porrected but slightly in front of the head; the terminal joint is very minute; the antennz have a tuft of curved hairs at the base, and their tips form a long reflexed club.

Hewitson, Esq., for allowing me the opportunity of figuring his unique specimen of this pretty undescribed species in illustration of the closely allied one from Zambesi in the Oxford Museum. It is somewhat larger than the latter, and wants the chalybeous gloss of the wings, which are black, the fore ones marked with nine spots of white of various sizes, namely, one at the base, on the inner margin, three of unequal size forming a triangle between the base and the middle of the wing, of which the outer one is the largest. These are followed by three near the centre of the wing, placed transversely, the one at the extremity of the discoidal cell and that between the first and second branches of the median vein being the largest, and the third, nearest the hinder angle of the wing, being small. Between the middle spots and the apex of the wing are two other white spots, of which the anterior is narrow, transverse, and tripartite. The hind wings have a small transverse line at the base, the centre of the wing being occupied by a broad pale buff bar, which is divided by the median and posteostal veins and their branches, which are broadly black, into five portions. The head is black, with two small white dots at the base of the antenne, the upper orbits of the eyes, and a small spot on the crown of the head of the same colour. The thorax is black, the patagia of the collar, the wing scales, and a dot on each side behind the wing scales of orange red; there is a slender white line across the front of the mesonotum (interrupted in the middle), and the hind margin of the sides of the scutellum is white. The abdomen is orange-red, the basal segment and a triangular spot in the middle of each of the four intermediate segments being black. INSECT MONSTROSITIES. Pirate XXXYV. This plate is devoted to a class of Insect Monstrosities of very rare occurrence, to which hitherto but little attention has been directed, and which are unnoticed in any of the general Introductions to the Science. The individuals in question belong to the group which has been termed gynandromorphous!, the specimens par- taking of the characters of both sexes, being, generally, bilateral ; the sexual characters (being for the most part the secondary ones) of one sex being exhibited by one side of the body and its organs, and the peculiarities of the opposite sex being seen on the other half of the insect. But, in the specimens before us, the body of the insect appears to be unisexual, and the sexual divarication is confined entirely to the secondary sexual characters exhibited by one or more of the wings only. The peculiar import of this strange modification, in a physiological point of view, is very difficult to be understood ; and from the great rarity of the individuals, and their small size, we can hardly hope to obtain specimens sufficient for the necessary examination of the internal characters of the primary sexual organs. The specimens hitherto observed belong, for the most part, to the Diurnal Lepidoptera, in which the sexual variation in the markings and coloration of the wings quickly catches the eye. Doubtless, however, they are more numerous than has hitherto been supposed; but they are, of course, liable to be overlooked in the vast multitude of species of all orders, where the external sexual distinctions are not conspicuously distinct. In some instances these modifications of the markings have been suggested to be mere chance variations in the shape or colour of unisexual individuals; but as they are not unfrequently accom- panied by sexual variations in structural characters (such as the shape or size of the wings), it is impossible to doubt that they exhibit a strange commingling of sexual distinctions. 1 This name was proposed by M. Lacordaire to supersede that of Hermaphrodites, which is more strictly applicable to those animals in which the generative organs of both sexes are normally included in the same individual, but which, nevertheless, require the presence of a second individual to effect the joint impregnation of the two individuals.

In my Arcana Entomologica, vol. 11. pl. LXXX (September, 1844), I published figures of two new Indian species of Papilio under the names of Castor and Pollux. P. Pollux (pl. LXXX, fig. 1) has the wings above nearly black, with very minute whitish incisures and a large white spot near the outer angle of the hind wings divided into four parts by the veins. I have had a number of males of this species. The other species, P. Castor, is larger, with dark brown wings, the fore wings having the white incisures gradually enlarged in size to the inner angle, and a row of nine submarginal whitish spots; whilst the hind wings have a submarginal row of seven arrow-headed markings and a broad row of spots between them and the middle of the wing. These broad spots are cream coloured and very decided in the male in the Oxford Museum, which is altogether darker than the females, which have these broad spots suffused with greenish brown scales, and of larger size, especially on the under side, where they extend into the discoidal cell, separated by the veins, The hind wings of the male are of the same shape as in the female, whereas in P. Pollux, male, they are more elongated, the third branch of the median vein terminating in a lobe more produced than the rest. By all subsequent writers these two species have been erroneously considered as sexes of one and the same species. In the Wiener Entom. Monatschr., as quoted above, Mr. George Semper of Altona, adopting the same opinion, has published figures of a remarkable specimen of P. Pol/ux (under the name of P. Castor), of which he has been so good as to send me a photograph, of which both the left wings are of the ordinary female character, as are also the anterior half of the fore- and inner (or anal) half of the hind-wings on the right side; whilst more than the inner half of the fore- and the outer or costal half of the hind-wing on the same right side are irregularly much darker and lighter, partaking of the characters of the darker male and lighter female. Sus-F aminy—PIERIDES. PIERIS PYRRHA. Prats XXXYV, Fic. 1. This is a very interesting example of the class of monsters above described, involving also the theory of ‘Mimicry’ which has lately been upheld to a considerable degree by the supporters of the Darwinian theory of Evolution. The family Pierides is typically well represented by our common garden white butterflies, white and yellow being the general colours of the great mass of the species, the fore wings generally also being tipped with black. In this particular species, the male, on the upper surface of its wings (as seen on the left side of figure 1), follows the normal character of the sub-family; but the female has the wings varied with orange, yellow, and black, and is, in fact, an excellent ‘mimic’ of some of the Heliconiide. Some traces of this colora- tion indeed are seen on the under side of the hind wings of the male, and are faintly visible through the wings when looked at from above. ‘The species is common in Brazil. In the individual represented in figure 1, from Mr. Hewitson’s collection, the two wings on the left side, and the fore wing on the right side, as well as the body, are entirely masculine; whilst the hind wing on the right side is, with the exception of a broad space along the costal margin, female. This space is, in the part towards the body, white, as in the male; whilst the outer half of the space is singularly confused with patches of white (male), orange, and black (female) scales. nv lee] 186 Orper—LEPIDOPTERA. EUCHLOE CARDAMINES. Pirate XXXV, Fias. 3, 4. The English orange-tipped butterfly, from the marked difference in the two sexes, and the common occur- rence of the species in lanes and pastures in the spring, is more frequently noticed, in a monstrous condition, than the ordinary white Pierides. A specimen, of which the wings on the left side are masculine, and those on the right side, wanting all trace of the orange markings, female, is represented in my ‘ Butterflies of Great Britain,’ pl. I, fig. 31. The insect here figured in plate XXXV, figs. 3, 4, from the Collection of Dr. Boisduval, is a male, but has the orange tip of the fore wings broken up, especially in the right wing, by white patches. The white portion of this right fore wing is, however, almost confined to the space between the third branch of the median vein and the lower disco-cellular vein on the upper side of the wings; and it is interesting to observe, that in this space the broader black apical margin of the female is seen, whereas the under side of this wing’is entirely masculine. In the apical portion of the left fore wing there seems to have occurred quite a contest between the male and female characteristic markings on the upper side, whereas on the underside the female marking is only seen in the space between the second and third branches of the median vein. Plate XXXV, fig. 8, represents the right fore wing of a specimen of the same species in the Collection of Mr. Edwin Brown, of Burton-on-Trent. This specimen is entirely female, except that the middle portion of the costal region of the right fore wing is marked with several irregular orange dashes above the large black discoidal spot both on the upper and under sides. The abdomen of this specimen appears, however, so far as may be judged by its dried and shrunk condition, to be masculine. Plate XXXV, fig. 9, also represents the right fore wing of a specimen of the same species observed by Mr. Geldart, to whom I am indebted for a sketch of it. The general appearance is that of a female, but on the upper side of the fore wing, on the right side, there is a small oblong dash of male orange scales in the space between the third branch of the median vein and the lower disco-cellular vein, immediately beyond the black discoidal spot. This dash shews through the white scales on the under side of the wing, but not a single orange scale is discernible on that side even by a strong magnifying glass. There are also two adjacent minute orange dots visible just above the lower disco-cellular vein. Another specimen of this insect is described by M. Boisduval as a variety of the female having an orange spot on the under side of the fore wings. In a short memoir in the Annales Soc. Ent. France for 1853 (2nd Ser. tom. x, p. 325, pl. IV, fig. 3), M. Bellier de la Chavignerie divides the so-called hermaphrodite insects into two series—Ist, those in which ‘Pun des sexes’ is ‘dans une plus grande proportion que l’autre’ (of which he had published an instance in Liparis dispar, described and figured by himself in the same Annales for 1849, p. 178, pl. VI, fig. 2, in which a large part of the right fore wing is coloured as in the female, whilst the whole of the remainder of this insect is masculine) ; and, 2ndly, those in which the two sexes are equally divided in the individual, which comprise by far the greater number of cases of these monstrosities, and of which, in 1835, M. Alexandre Lefebvre gave a list of 47 of such Lepidopterous monsters: to which M. Bellier added another instance in the volume of the Annales for 1852, being a specimen of Euchloe cardamines, of which the left side was entirely female. M. J. Fallou has published (Annales Soe, Ent. France, 5th Ser. 1871, p. 369, pl. V, figs. 7 and 8) the description and figures of an aber- ration of 2. cardamines, of which the body was female (containing eggs), and the hind wings entirely and the fore wings for the most part were female, whilst on the upper side the right fore wing was marked by several narrow orange streaks on the extremity of the costa and apex of the wing, whilst the left fore wing had a small triangular dash of light orange near the inner angle. On the upper side the fore wings may be said to be cut into three nearly equal longitudinal parts, the costal and inner third being female, whilst the central part is masculine, with the orange colour extending into the cell, the apical margin in this part is marked with three triangular patches of green scales. It was taken near Beaumont-sur-Oise. 1 This specimen is in the Collection of Mr. Henry Doubleday. A similar specimen is figured by M. Bellier in the Annales of the French Entomological Society, 2nd Ser. tom. x, pl. IV (1853). Fammnpy—PAPILIONID. Sus-Famity—PIERIDES. 187 ANUEO C HARI S) Vel PsP E: Pratt XXXV, Fies. 11, 12. In the Hopeian Collection is preserved the monstrous specimen of this pretty species from Sierra Leone here figured. The ordinary male character of the specimen is shewn on the left side of figure 11, exhibiting a large red spot on the broad apical margin of the fore wing, the dise of which is entirely white, and the white hind wings with black marginal spots, to which two small somewhat oval ones are attached, extending into the dise of the wing. The ordinary character of the upper side of the female is shewn in figure 12, shewing the large broad apical spot, and an oblong one on the inner margin of the fore wings (which are dilated below the middle of the apical margin), and the hind wings marked with a dark subcentral fascia as well as the marginal spots. In the specimen before us the left side of the insect is entirely male, and the wings on the right side are female in form, and the hind one is also female in markings; but the fore wing has the broad apical dark margin marked with an irregular series of red spots, thus partaking of the character of the male. GONOPTERYX RHAMNI. Prats XXXV, Fie. 2. The ordinary character of this very common butterfly is the entirely sulphur-yellow colour of the wings of the male, and the greenish-white colour of those of the female. I have seen several monsters of this species in which one or more of the wings exhibit a combination of the colours of the two sexes. In the specimen here figured (fig. 2) from the Collection of Herr Staudinger, of Dresden, the fore wing on the right side is female, with the anterior and posterior margins masculine, and with two orange dots on the dise beyond the cell; the right hind wing is entirely masculine ; the left fore wing has the anterior half mascu- line, with two spots at the end of the discoidal cell, and a spot on the apical margin as in the female; the posterior half is female, with a bipartite orange spot on the dise beyond the cell; the left hind wing has the costal half female, and the inner half male, with a pale spot near the anal angle. Plate XXXV, fig. 10, exhibits the right fore wing of a specimen of the same species in the Collection of Mr. F. Bond, which has the two wings on the left side, and the hind wing on the right side feminine ; but this right hand fore wing is confusedly divided (for the most part longitudinally) between the male and female colours. The specimen was taken near London, Mr. F. Bond possesses another specimen which is entirely masculine except the costal region of the fore wing on the left side, which is female, with a small narrow yellow dash in the middle of the costal edge. Mr. F. Bond has also recently obtained from the Collection of Mr. Edmunds, of Worcester, two specimens with irregular markings of the two sexes, but with the peculiarity that the markings are exactly similar on the two sides, the under surface of the wings, moreover, shewing the same markings as on the upper surface. In one of these specimens the basal half of all the wings is masculine, with slender white dashes on the chief veins, whilst the apical half is feminine, the body being also female. In the other specimen the fore wings have an oval spot of the female colour near the apex, an elongated dash between the second and third branches of the median vein, and the inner margin with a broad border of the female colour. In the hind wings the discoidal cell is of the female colour, from which three broad stripes of the same colour extend to the outer margin of the wing, each occupying the alternate space between the longitudinal veins of the hind wing beyond the cell. From the regularity of the markings of these two specimens, and their identity on the two sides, one is almost tempted to fancy the male colour may have been discharged in the pale parts by art. The Royal Museum of Berlin also possesses two interesting specimens of the same species. In one the left fore wing is masculine, and the two hind wings are feminine, except that the left-hand hind wing has a central narrow stripe of male colour running from the base of the wing, over the ordinary discoidal orange spot, and extending to the outer margin of the wing; the right fore wing is female, except that the costa for two-thirds of its length from the base, a narrow longitudinal streak running through the discoidal cell from the base to below the apex of the wing, and a dash parallel with the inner margin, are masculine. The other Berlin specimen has the right fore wing and the anterior half of the left fore wing female, the 2B2 188 OrpER—LEPIDOPTERA. posterior half of the left fore wing being masculine: the right hind wing is female, with a large yellow patch near the outer angle, and the left hind wing is female, with a yellow stripe extending from the discoidal spot to the outer margin, the outer angle of the wing, and two irregular spots between the angle and the anal edge of the masculine colour. Famiry—NYMPHALID 2. SIDERONE TSIDORE Pirate XXXV, Fics. 6, 7. Mr. Hewitson possesses a curious specimen of this Brazilian species here figured. The ordinary character of the male is shewn on the left side of figure 6, and the corresponding side (that is, the right side) of the under surface shewn in fig. 7. The wings of the female are pale buff, slightly darker at the base, with a broad black apical spot in the fore wings. In this sex the outer angle of the hind wing is more prominent than in the male, the inner margin of the hind wing being shorter than in the male. In Mr. Hewitson’s specimen the two wings on the left side and the hind wing on the right side are masculine (except that the latter has a female coloured spot in the middle of the costal region, which is more conspicuous on the under side of the hind wing). The right fore wing, however, presents on its upper surface a complete mélange of the colours of the two sexes: the base, however, being masculine; whereas the under surface of this wing offers no distinction from the ordi- nary under side of the male. Famity—SATYRIDA. HIPPARCHIA SEMELE. PuatE XXXV, Fie. 13. In Mr. F. Bond’s fine Collection is preserved a specimen of this common British species, which in size and general appearance, as well as in the structure of the fore legs, is a male insect, but of which the left fore wing does not exhibit the peculiar male rugose portion of the dise to its full extent!, whilst the apical portion is marked as in the female. Mr. F. Bond also possesses a male specimen of this species, with the apical half of all the wings marked as in the female. Famity—MORPHID. In Mr. Hewitson’s Collection is preserved a specimen of Morpho Sulkowshyi Koll. (11. Ganymede, Westw. Gen. D. Lep.), in which the fore and hind wing on the right side, and the fore wing on the left side, are mas- culine. The left hind wing, however, on the upper surface has two-thirds of the basal portion blue, but not quite so brilliant as the right fore wing; the apical one-third of the wing (as far as and including the ocelli, as seen through the wing) is pale brown, with two narrow subapical bands not at all lunulate; the anal patch is as in the male, but much more diffused with brown; the black and red markings as in the male. On the under surface the left fore wing is throughout more strongly marked with darker brown, and the ocelli are rather larger than in the opposite hind wing. 1 Tn this species the greater portion of the dise of the wing is covered with ordinary shaped oval scales, which are affixed to the wing in little cups placed transversely in rows at equal distances apart ; but in the rugose portions of the fore wings, characteristic of the male, the membrane of the wing is covered quite irregularly with a vast number of the small cups, the characteristic male scales or plumules (as they are termed by microscopists) occurring in these parts in vast numbers. These plumules are either of a very elongated oval form, or are almost linear, with the surface, however striated, and the apex terminating in a small tuft of very fine bristles. These scales are implanted in the cups by a minute bul- bous base, from which extends a short extremely slender cylindrical portion. Although, however, occurring in such vast numbers, these scales are not observed when the insect is at rest, or dried in a cabinet, the roughness which is observed in those parts of the wings being produced by usual oval scales implanted amongst them, sticking out as if thrust upwards by the dense mass of male plumules beneath. Fammty—BOMBYCIDZ. 189 Famity—LYCANID. POLYOMMATUS ADONIS. Prats XXXV, Fie. 5. In Mr. F. Bond’s Collection is a specimen of this pretty insect which, on the under side, has entirely the appearance of a female individual: on the upper surface, also, the two wings on the right side, and the hind wing on the left side, are female; but the fore wing is dashed, especially on the anterior half of the wing, with longitudinal stripes of the brilliant blue colour of the male. LEPIDOPTERA HETEROCERA. Famity—BOMBYCID. LASIOCAMPA QUERCUS. Prats XXXV, Fic. 14. The specimen here figured is contained in the Collection of Herr Staudinger, of Dresden, and exhibits a curious mixture of both sexes, the fore wing on the right side alone being unisexual and of the enlarged female size and colour; the anterior half of the fore wing, on the left side, is also coloured as in the female; but this wing is small in size, as in the male, and the hind half is curiously mottled with the darker and lighter colours of the two sexes; the red brown not so dark as in ordinary males; the left hind wing has the costal one-third of the pale female colour, the inner two-thirds being of the richer colour of the male, with two large pale oval discoidal spots; the hind wing, on the right side, has the outer two-thirds of the wing coloured as in light- coloured males, with four pale submarginal spots ; the inner one-third is of the pale colour of the female, but with a red-brown spot opposite the extremity of the body. The antennz are shorter and not so much pectinated as in the male; the thorax and base of the abdomen are broad as in the females, but the abdomen is small, conical, and shorter than in the male. Mr. F. Bond also exhibited at the February meeting of the Entomological Society of London, 1868, another specimen of Lasiocampa quereus, with the wings irregularly coloured, with the antenn also apparently irregu- larly sexual. M. Guénée has also described and figured a specimen of the same species in a memoir, recently published, upon certain Lepidoptera in the Museum of Geneva (pl. annex. fig. 8, with details), which exhibits a curious mixture of sexual characters. The two wings on the right side, the hind wing on the left side (except a narrow pale streak extending from the middle of the disc to the outer margin), and the inner half of the fore wing on the left side, are apparently those of the male; but the anterior or costal half of the left fore wing is enlarged and pale coloured, as in the female. The body is thick, as in the female; the antennw are intermediate in structure between those of the two sexes; and the abdomen was found to contain imperfectly developed eggs— the outer organs of generation being also imperfect. ORDER—NEUROPTERA. Fammy—LIBELLULID&. CALEPTERYX VIRGO. PuatTE XXXV, Fie. 15. Mr. McLachlan has kindly allowed me to figure from his collection a French specimen of this common insect partaking of the markings of the two sexes. The body is green, with the wings very slightly greenish- hyaline; the anterior on the right side only slightly and irregularly marked along the middle of the inner por- tion with brown spots; whilst the anterior wing on the left side bears a very large dark blue oval patch as in the ordinary males. The two hind wings are unicolorous. The extremity of the abdomen has been much injured by having a wire passed up the body, the eighth or terminal segment alone exhibiting small black horny conical points. ORDER-HEMIPTERA.

Denny placed in my hands for examination a parasitic insect, found upon the beaver, which seemed at first sight half-way between a flattened flea and a diminutive cockroach, and which appeared to me to belong to none of the recognized Orders of hexapod Annulosa. I read a description of this insect with figures, under the name of Platypsyllus castorinus, before the Ashmolean Society of Oxford, during Michaelmas Term, November 9, 1868; but, as that Society is very dilatory in pub- lishing its Proceedings, I sent a short notice of the characters of the insect for publication in ‘The Entomo- logist’s Monthly Magazine,’ which appeared on the Ist of October, 1869, vol. vi, p. 118. By a singular coincidence, Herr Ritsema of Leyden published a notice of the same insect on the 15th of September, 1869, in the ‘ Petites Nouvelles Entomologiques,’ under the almost identical name of Platypsyllus castoris, regarding it as a flattened flea, and consequently as belonging to the family Pulicide—an opinion which the structure of the mouth proves to be untenable. Subsequently, Dr. J. Leconte, having carefully examined my specimen, came to the conclusion that it was a Coleopterous insect (‘ Nature,’ June 27, 1872), considering the trilobed structure of the mentum to resemble that of Leptinus, the lateral processes in which, however, are only narrow spines projecting over the gular plate; the antennz resembling those of Gyrinus and Parnus, other parts exhibiting an ‘ unmistakable affinity’ with the Staphylinide, Silphide, Corylophide, and especially the genus Limulodes of Matthews in the family Trichopterygide, with large and dilated sterna. The same gentleman has since obtained other specimens of the insect, and has sent a memoir on it to the Zoological Society of London, published in the Proceedings of that Society for 1872. The abnormal economy of the insect, its remarkable structure, the apparent want of mandibles (which I have failed to discover, although I have dissected several specimens subsequently received in spirits through the kindness of Herr Ritsema), our ignorance of its transformations, and the possibility that the creature may be Homomorphous in the larva and pupa states, induced me and still induce me to hesitate in regarding it as belonging to any of the recognized orders of insects. I therefore here provisionally retain for it the original ordinal name which I proposed in ‘ The Entomologist’s Monthly Magazine.’ Corpus ovale, valde depressum, coriaceum, setigerum; os (mandibulis?) mazxillis, labio palpisque quatuor instructum ; antennz laterales, postice reflexe, tri-articulate, articulo ultimo (ut in Pulice) annulato ; prothorax magnus, scutiformis, margine postico sinuato ; mesothoracis scutellum triangulare ; al antic coriacew, plane, venis carentes, breves, coalite, basin abdominis attingentes ; sutura recta; ale postice obsolete; sterna omnia maxima, plana; pedes cursorii (saltatorii?), tibiis calearatis, tarsis quinque-articulatis, bi-unguiculatis ; meta- morphoses ignote; victus parasiticus in Castorem, more Pulicis.

This family is composed of two genera only—CAMPODEA, Westw. Trans. Ent. Soe. vol. ii. p. 231; and TAPYX, Haliday, Trans. Linn. Soe. vol. xxiv. p. 441. The former is at once distinguished by having the body terminated by two long slender multiarticulated filiform appendages resembling a pair of anal antenne. The species of which it is composed are small and elongated like narrow Staphylini, but of a white or pale colour. 20% 196 OrpDER—THYSANURA. ‘ They reside in the earth, and may occasionally be seen whilst digging in garden ground. They have recently received considerable attention from the fanciful theory which has been applied to them by Sir John Lubbock, that they constitute the primary type of form from which the whole of the class of insects has been evolved. Genus—IAPYX. (Haliday, Trans. Linn. Soc. xxiv, p. 442.) This Genus comprises species of larger size than the Campodew, which bear a striking resemblance to im- mature Forficule, the body being terminated by two exarticulate horny, forceps-like appendages.

They were sent to me by Giglioli as a new species of Nycteribia, but a slight examination con- vineed me they had no affinity with that genus beyond their apterous condition and bat-parasitism ; whilst a more careful investigation of them, and of a closely allied species captured upon another species of Molossus bats in the West Indies, shewed that they possessed a haustellum very similar in form to that of the genuine Hemi- ptera-Heteroptera. From the rows of strong flat spines with which they are armed, I proposed the generic name of Polyetenes, which Sig, Giglioli adopted in his short description of this and some other parasitic insects pub- lished in the ‘ Journal of Microscopical Science,’ with small and quite unsatisfactory figures.

Fig. B* represents the head seen from beneath, shewing the lunate clypeus (?) the double curved row of spines in front of the proboscis, the two antenni, and the two trabecul, the lower row of spines of which is bent inwards towards the proboscis; the three-jointed proboscis, shewing an oval portion at the base, which seems to repre- sent the labrum and two of the elongated internal sete. Also the transverse row of spines along the posterior margin of the head, with two strong: spines at the outer angle. Fig. A, one of the thick fore legs, in which the tarsal joints appear soldered together, probably owing to the dilatation of the outer covering by the growth of the inclosed limb. Fig. B exhibits the tarsus of one of the fore lees, and fig. C the extremity of the tarsus of the other fore leg: in both figures are to be seen, within the terminal joint, the ungues of an inclosed tarsus, shewing that the specimen was about to cast its skin1, and con- sequently proving that the species undergoes the metamorphosis dimidiata, with either a complete or semicom- plete pupa. Fig. D represents one of the four posterior tarsi, shewing the pulvillus as well as the ungues of a different form to those of the fore leg, one being simple and slightly bent, whilst the other is very deeply notched. Fig. E represents the extremity of the same tarsus, shewing the ungues and pulvillus of the inclosed limb. Fig. F shews one of the spines of the lateral margin of the clypeus, with the cup-like tubercle in which it is inserted. Fig. G, the cup of one of the flattened spines (fig. H) of the anterior margin of the trabecula. Plate XXXIX, fig. A, represents the other sex, having a larger body and a curved horny appendage at its extremity beneath. Plate XL, fig. A, represents the under side of the head and prothorax, with the fore legs (the apical half of the tibie and tarsi cut off). In this figure the transverse row of comb-like spines (29 in number on the pos- terior margin of the head), and the similar row with 49 spines, are represented, having been rendered visible by the treatment with Canada balsam in which the specimen was immersed. The delicate transverse striature of the clypeus, the partial withdrawal of one of the set of the mouth from the proboscis at *, as well as that of three of the sets from the longitudinal opening of the proboscis towards its apex, and the two strong pairs of muscles for the movement of the fore leg, are shewn. In this sex (as seen also in pl. XX XVIII, fig. 4) the lower row of spines of the trabeculz is not developed into a comb as in the opposite sex. Fig. D shews the anterior tibia and tarsus, the triarticulation of the latter being more distinctly shewn than in the other specimen. Fig. E, one of the four posterior tarsi, shewing the lobed base extending to the tip of the first joint. Fig. C, three of the spines of the upper margin of the trabecula. Fig. B, the extremity of the body seen beneath, shewing a transverse oval lobe with two setose pupilla and the strong curved horny appendage (ovipositor ?). * The question here naturally arises whether, upon the next shedding of the skin, indicated by the already perfect state of the distal extremities of the inclosed limbs, the dorsal scales resembling elytra would be further developed either into elytra or hemelytra ? CLASS ARACHNIDA ORDER-—ADELARTHROSOMATA’ Westw. Famity—CYPHOPHTHALMID. This family, hitherto composed of a single genus, Cyphophthalmus, founded upon a single species, C. duri- cornis, inhabiting the caves of Carniola, was proposed by Herr Joseph in the Berlin Entomologische Zeitung, vol. xii, p. 241 and p. 269, pl. i. It is nearly allied to Phalangium. A second species of the group was forwarded to me by Herr Snellen van Vollenhoven, from the Royal Museum of Leyden, as a native of Sumatra, and as a species of Trogulus. As it differs in several respects from the type of the family, I have formed it into the Grinus—STYLOCELLUS, (Prats XXXVII, Fies. 7, 7 a, corpus infra visum ; fig. 7}, idem e latere.) Cephalothorax dorso integro, absque impressione semicirculari dorsali; lateribus in cornua duo brevia por- recta, apice ocelligero; chelicere palpis breviores, articulo basali dimidium articuli cheliferi longitudine «quanti ; chele simplices nec serrate: spiracula ad basin abdominis rotundata nec lunata; pedes 8, fere zquales, tibiis biarticulatis, tarsis biarticulatis, articulo basali brevi, secundo multo longiori crassiori subtus fisso, ungue unico terminali instructo (fig. 7); pedes antici modice elongati absque spina ad angulum internum articuli basalis ; abdomen ovale convexum e segmentis septem coalitis, formatum.

I have seen a closely-allied species of a ferruginous colour from Java in the collection of the British Museum. * Forty years ago I proposed this term for those Trachearian Arachnida which have the ‘abdomen annulated, although occasionally in an indistinct manner,’ the other orders of Arachnida being named by Dr. Leach—1. Dimeroso- mata (spiders) ; 2. Polymerosomata (scorpions) ; 3. Monomerosomata (mites) ; and 4. Podosomata (Pyconogonum and Nymphon). The term Arthrogastra has recently been applied to my Adelarthrosomata, to which, notwithstanding their different mode of respiration, the scorpions have been unsatisfactorily added. Famity—TROGULIDA. 201 Famity—CRY PTOSTEMMID.. The Genus Cryptostemma of Guérin-Méneville is formed of a single species received by M. Guérin from the late Herr Westermann as a native of Guinea. It is nearly allied to Phalangium and Trogulus, but the eyes are wanting and the chelicere are porrected and pediform ; the cephalothorax is square, with the anterior margin porrected in form of a clypeus; the abdo- men is as wide as the cephalothorax, and twice its length, being oblong, with the posterior angles rounded. The legs are very unequal in length, the second pair being the longest, with 4- or 5-jointed tarsi (Guérin-Mén. Rey. Zool. 1838, p. 11; Dict. Pittor. d’Hist. Nat. pl. DXXXIX, fig. 7; Walckenaer, Apt. i. p. 131, pl. XLVI (not XX XIX), fig. 4). An allied form was captured by Mr. H. W. Bates in his Amazon researches, which constitutes a distinct genus, which I have named Grnus—CRYPTOCELLUS.

It is with great pleasure that I am here enabled to introduce this interesting Genus into the British Fauna, a new species having been captured in Dorsetshire by the Rev. Pickard Cambridge, who has kindly placed it in the Hopeian Collection, and allowed me to describe and figure it in this work. The Genus is composed, for the most part, of European species, the type being the Phalangium tricarinatum 2D 202 Orper—ADELARTHROSOMATA. of Linneus (dearus nepiformis Scopoli Ent. Carniol. fig. mala). A number of European species are described and figured in ‘ Die Arachniden’ by Hahn and Koch, namely, Trogulus nepiformis, Latr. (tricarinatum, Linn., carinatum, Fab.)

The palpi in this species have the three terminal joints more equal in size than in the large typical species of the genus, the third being but little longer than the second, and nearly equal in size to the fourth (fig. 64) ; the tarsi are irregular in the number and size of their joints; those of the first feet being four-jointed (fig. 6c) ; those of the second feet are three-jointed: the first joint very short, the second about twice as long as wide, and the third long and broad ; whilst the tarsi of the third and fourth legs are four-jointed like the first pair, but the second joint is nearly as long as the fourth, and the third is as small as the basal joint. The junction of the cephalothorax and abdomen, and the segmentation of the latter, are very indistinct owing to the squamosity with which they are covered, and which appears to be caused by minute elevated tubercles emitting broad sete, which in some specimens appear to become matted together, giving them a less rugose appearance than the others.

Page 121. Genus Derecyrta. Having received from Mr. Reed, the Curator of the Museum at Santiago, Chili, since my descriptions of the species of this genus were printed, both sexes of the Chilian insect described by Philippi under the name of Brachyxiphus grandis, I am now able to state that the specimen he gave as a female is, as I supposed, a male, and that its female, hitherto undescribed, agrees with it in having two marginal cells in the fore wings. The female measures 1 inch in length and 22% lines in the expanse of the fore wings, it has six instead of five of the abdominal segments entirely orange red, and the wings are not so darkly stained with brown as in the male, being of a richer and paler uniform golden brown colour. Having cleared up these sexual differences, it will become necessary to adopt the name Derecyrta grandis in leu of D. bicolor, notwithstanding the impropriety of Philippi’s name, the species not being larger than that described by me. Br. flavipes will form a fourth species in the genus. Page 158. pyris Halidaii. The reference to Plate XVI, Fig. 6, should follow the Synonym, Haliday, Ent. Mag. ly, p. 433. Page 165.
