Westwood (First Hope Professor of Zoology at the University of Oxford), M.A., F.L.S., etc., etc., with many other distinctions and memberships of learned societies in all parts of the civilised world, which were the natural results, fully merited, of the enormous amount of valuable work in many branches of Zoology and other subjects, which he accomplished during a long and industrious life—to the memory of this great and faithful master of Natural Science, I feel it an honour to dedicate this volume of my monograph. Professor Westwood’s writings and drawings illustrative of every order of insects, in addition to his palzeographic and other works, are well known and highly valued throughout the world of Zoological and Archzological Science. They are so numerous that a list of them would fill a small volume ; and up to the period of his death he was as unwearied in giving to the world the results df his investigations, as he had been in the earlier and middle portions of his long and useful life. If he had produced only his great work ‘‘ An Introduction to the Modern Classification of Insects,” which was published in two closely-printed volumes in 1839-40, the entomological world would have been laid under a deep debt of gratitude to him; for the work was such a masterpiece of learning, as to constitute it a valuable encyclopedia in itself of the subjects of which it treats. We need another man, gifted with Westwood’s abilities and enthusiasm, to sup- plement his labours, by giving us two or three additional volumes, constructed on the same plan, in which should be in- corporated the wonderful results of the investigations in Entomology of the many workers among all nations during the 50 years that have passed away since Professor Westwood wrote the last line of his great treatise. Such a work must be undertaken sooner or later—the sooner the better. Even then, amongst so much that has been splendidly accomplished by others, his contributions quite down to the year of his death will be found to be so numerous) and so valuable, as to bring him into continual remembrance. His work will be his monument while Entomology is studied ; and no words of mine, or of others, are needed to enhance his fame. One of the rewards of those who strive to enrich the world with their talents, is that, while ‘their works do follow them,” they also remain with us and continually remind us of what it is possible for an earnest worker in any department of heaven-inspired labour to be to his day and generation, and to the generations that are to come. And now, with the highest sense of the honour, I remind myself that Professor Westwood was one of the earliest subscribers for a copy of this monograph; that he took great interest in its progress, as his letters to me evidence ; and that he willingly accepted my dedication of it to him. Therefore, whilst I regret that he was not spared to see its completion, I am glad of the privilege of dedicating this First Volume to his memory, with the earnest hope that the beautiful Science which he adorned and advanced by his gifted labours, may attract an ever-increasing number of equally gifted and devoted workers in the future of Zoologi- cal investigation. ROBERDL H. FP. RIPPON, January, 1900. (3) yy : Ht PREFACE. This Monograph is the result of the author’s desire to leave behind him some memorial of his life-long love for the marvellous and varied works with which our God has so abundantly stored and adorned this beautiful world. He was anxious to leave something which should be permanently useful to all those who cared to study at least one small part of those creations which the author (while he fully accepts and rejoices in the teachings of Evolution) nevertheless regards as the crystalised thoughts of our loving Creator. The author had no particular ambition in employing his pen and pencil, to attain to more than this; feeling as he does that it is impossible for anyone to propose to himself any worthier task than to try and make the world a little richer in some way, intellectually or spiritually, for his having been an inhabitant of it. He hoped that (whilst he was very poorly equipped with financial resources) by doing the whole work of this monograph with his own hands and brain, he would be able to make it pay its expenses, which he was aware could not be small. As a matter of fact, even under these conditious the work thus far has cost very much more than has been received for it, and the labour involved has been much greater than was expected, and these have been two of the many difficulties which have tended to delay the completion of it for so much longer a period than the author anticipated. For several years preceding the commencement of this undertaking the author had contemplated monograph- ing some special group of marine or land shells, or some particular family of butterflies or moths (for either of which he could find plenty of materials in his own collection as the nuclei of a more extensive survey), and publishing it himself at as small a price as possible. But as itis always so much easier to originate ideas than to carry them out, the author was continually reminded by unhappy experience that such an undertaking, with his limited resources, could not be entered upon with a light heart, even if it were to be attempted at all. However as the years passed, and he was unwilling to delay indefinitely, he decided to forego the larger idea which he had in his mind, and which some conchological friends were anxious he should enter upon, and by selecting some very small group of butterflies which had not been too exhaustively worked up, to endeavour to produce as complete an illustrative monograph of that group as he was able, limiting it to a definite and not excessive number of parts. The Ornithoptera seemed to afford just the subject for his purpose. They were not very numerous in species, they were very magnificent in character (next to the morphos, the most beautiful of butterflies), and no monogiaph of what was then called a genus existed. Several of the varieties had only been described without figures, or figures of both sexes did not exist; these descriptions and figures were scattered far and wide through the pages of Entomological literature, adorning such works as Cramer’s ‘‘ Papilio Exotica,” Felder’s ‘‘ Reise Novare,” Westwood’s “ Cabinet of Oriental Entomology,” Doubleday and Hewitson’s ‘‘ Genera,” Gray’s “ Catalogue of Lepidopterous Insects of the British Museum,” Boisduval’s ‘ Species Géneral,” ‘‘ The Voyage of the Astrolabe,” and the Transactions and Proceedings of Societies, British and Foreign. Many of the figures adorning these works were magnificent, and all the descriptions most useful and instructive—albeit the very long latin diagnoses of Felder were trying to the ordinary student. Buta great number of synonyms had unavoidably been created; slight new varieties were continually being described as species, and there was much confusion with regard to the sexes, so that some of the species did not always get their proper mates—a grave irregularity which it was most desirable should be remedied at the earliest possible moment. To the ordinary student in any department of zoology it is ever most diff- cult, if he have no big or costly library of his own, to obtain the information which he requires about his special subject of investigation: often much time and labour have to be expended, and the results are still unsatisfactory. Monographs have a very special raison d’étre. “They supply a very urgent need, if they are properly written ; and so it seemed to the author that he could wisely employ his time and energies in the preparation of an illustrated monograph which should, within the covers of one or two volumes, furnish to the student of the Ornithoptera a fairly exhaustive view of the subject up to the date of completion, with illustrations of each form so accurate that it should be easy to determine any species of the group with sufficient facility to render such a work welcome. In the year 1884 the author spoke of his proposal to his friend the late Philip Henry Gosse, F.R.S., and the well-known author of some delightful works on marine and land zoology, and whose paper ‘‘ On the Clasping-organs Ancillary to Generation in certain groups of the Lepidoptera,”’ published in the Trans. Linn. Soc. Lond., in April, 1883, included his investigations of this subject in 12 species of Ornithoptera.* The following extract from his letter contains Mr. Gosse’s reply : ‘Sandhurst, Torquay, 11/1/84. ‘« My dear Friend, : . : ; . ) : : ; - : : : 2 : tn og I rejoice with you in the acquisition of 2 Ornithopt.

In addition to his own masterly treatment of this subject Mr. Gosse quotes from De Haan's Bijdvagen tot de Kennis des Papilionidea, in the ‘ Verhandelingen over de natuurlijke geschiedenis der Nederlandsche overzeesche bezittingen (Trans. regarding the Nat. Hist. of the Dutch Over-the-Sea Possessions,”) giving references to P. Amphrysus, which are illustrated in that paper by 3 figs.; and also from Dr. Burmeister's Lepid. d. l. Rep. Arg., p. 21. It is almost needless to say the author availed himself of Mr. Gosse’s kindness. But nearly five years elapsed before he commenced the monograph, when there seemed a prospect of his relieving himself of the responsibility of being his own publisher, and devoting himself entirely to the production of the work. However, before the issue of the first part he found it would be wise to be his own publisher, and altogether to take every responsibility upon himself, Since then he has laboured unceasingly on this work, with many difficulties financial, of ill-health, and other obstacles, to contend with—ever full of hope and determination—assured that He who had helped His servant thus far, would give him in due time the joy of completing the work. It will be readily understood why he has had, and may have for a while longer, to make such demands on the patience of his subscribers, when it is understood that in addition to all the work needed in preparing the letter-press, and drawing the plates, the author colours with his own hands every copy of every plate that is published, and personally delivers or sends the parts to each subscriber when ready for them, But he trusts that whatever faults and shortcomings the work may exhibit, (and he is fully conscious of many of them) it will still be regarded by every lover of exotic entomology, as much better to have been done than to have been left undone—a conclusion which will render him grateful to God and man. At the commencement of this monograph, the miaterials which would enable us to decide upon the true rank of the Ornithoptera among the Papilionidz were unfortunately much more restricted than at the present time; and in the future we may confidently anticipate an accumulation of still more valuable and instructive examples of the group, which may modify or even completely alter our views on the subject; for there is no finality in entomology any more than there is in other departments of science. But even at an early period of this work, a close study of the different forms composing what was then called the Genus Ornithoptera convinced the Author that the position assigned to the so called genus among the Papilionide, by nearly all authors, was the correct, or nearly correct one ; that these insects, though in some respects it was difficult to say in what important characters they differed from the other Papilios, for several good reasons were allowed to take precedence of them, asa distinct genus ; that the number of good, substantial species was really very small—indeed, more restricted than even was at first suspected—despite the great number of names that had been given to them; and that, while the number of local forms and varities was already large, it was certain to become much larger, as new and especially insulated localities were explored. Now this is exactly what has been taking place. The subsequent great increase of materials has not modified these impressions, though it has greatly enlarged them, and given him a sense of the glory of the group, which may be compared with the feeling one experiences when thinking of the even greater advance in discovery and knowledge, in Ornithology for example, of the numerous species, and the astounding beauty and strangeness of form, of the Birds of Paradise. Indeed, as the author has ventured to suggest in another place, seeing that the most glorious of all the Ornithoptera, those of the genera Schoenbergia and A&theoptera, seem to inhabit geographical areas identical with or near the metropolis of these birds, and are as beautiful in their way as the Birds of Paradise, these species of Ornithoptera may well be called the BuTTERFLIES OF PARADISE. For reasons recorded in their own proper place in this work, it was found necessary at first to divide the genus Onithoptera into three sub-genera—later on to give these full generic rank, viz., ORNITHOPTERA (with its section Priamoptera), TRoGoNOPTERA, at that time consisting of only one species, and PoMPEOPTERA. At the same time there were two remarkable forms, one a ¢@ and the other a 2 (only one example of each) whose position in the group it was difficult to understand. These were De Haan’s ¢ Tithonus and Gray’s ? Victorie. These were obviously distinct as species from any of the Priamus group, whilst appearing to have a close affinity for it. The question then arose, is the ¢ Victore the mate of the & Tithonus, or do they each belong to distinct species? Ultimately the discovery of the gorgeous and remarkably formed ¢ of Victorig and many more ? 2 by Mr. Woodford in the Solomon Islands, and, a little later on, the description, by Mr. Salvin, of the allied form Regina, and the discovery of De Haan’s Tzthonus (both sexes) in the island of Waigieu, enabled us to more properly study their affinities with the group to which they belong, with the result that they fall into two distinct genera, one of which should immediately precede, and the other succeed, the genus ORNITHOPTERA (or the Priamus group, as it was called). The addition of the tailed Sch. Paradisea to the Ornithoptera supplied the genus for Tithonus. It is to be noted that all the members of the genus ORNITHOPTERA, in the $ sex, were distinguished by the presence on the anterior wing of a pupeform sericeous brand; this character is also found in AZrueopTerRA, while the form and colouration of the ¢ is quite distinct from those of the Priamus group, and the ¢ is also quite unlike any? of the genus OrnirHoprera. On the contrary both Paradisea and Tithonus $ ¢ possess no stigmatic brand, their abdominal marginal fringe is very long, dense, and white or light sienna tone, and their females are quite different in appearance from those of Victore and its congeners, and though somewhat like those of Ornithoptera, are yet abundantly distinct from them. Victorie therefore became the type of ASTHEOPTERA and Paradisea of the genus SCHOENBERGIA (or, as Pagenstecher suggested, but without characterising it, a subgenus). The genera Troconoprera and Pomproprera are, in the ¢, possessed of an abdominal marginal fold or pouch, concealing the androconia, and the ¢ ¢ of the red and black South and Central American Papilios, or as the Author proposes to call them ORNITHOPTERINA, are possessed of a similar character in the same position. In addition to these genera it was necessary to admit Drury’s Papilio Antimachus, and Hewitson’s P. Zalmoxts (both West African species) to the ranks of the Ornithoptera, to place them undoubtedly before ScHOENBERGIA, and to include them in the genus Drurya (created by Aurivillius in 1880) for the type 4 ntimachus. It was suggested to the author that White’s Ridleyanus, also a W. African species, should come into the group, but as he has shewn, this papilio is by no means related to the Ornithoptera. With regard to the Ornithopterina they will have to be separated into 2 genera at least, which when properly studied will reveal some remarkable analogies to both ORNITHOPTERA and PoMPEOPTERA. As we have therefore a number of genera included among the Ornithoptera, it appeared to be wise to regard them as worthy of being associated together as a tribe, the Papilionine tribe TROIDES, a generic name given to DSI (0) this group of butterflies in 1816 by Hubner, and adopted by Mr. Rothschild fin his very valuable and masterly ‘Review of the Papilionide of the Eastern Hemisphere, exclusive of Africa, (Novitates Zoologice, Vol. III., 1895) ”] as the generic name of the whole of the Ornithoptera without distinction, therewith introducing a trinomial and possibly quadrinomial nomenclature, which it is difficult to believe he will not, with his great knowledge, ultimately modify, as being cumbersome and inconvenient to the ordinary student. That the whole of the so-called species included in the author’s restricted genus Ornithoptera, or the old Priamus Group, may well be regarded as geographical forms of the type species Priamus, it will be wise to admit; and this most entomologists are agreed upon. ‘The superficial differences, 7.¢., those of pattern, are not too great, especially in the ¢ sex, and the external structural characters so far as they have been studied, do not appear to diverge in any important degree throughout the multitude of named forms, from the type species. It would appear that the whole of the Ornithoptera are in a very unstable condition, none of the forms appear to be as approximately permanent in pattern and colour as Vanessa atalanta, V. Urtice, Danas Archippus, or even the American Argynnidz. In both sexes it is almost impossible to find a specimen in which the markings are symmetrical on both wings, on either surface; and still more difficult to find two examples which in size and markings are absolutely alike ; while the intensity and quality of colour differ to a wonderful extent throughout the group. Of course all this instability is intended to enable different members of the group to adapt themselves to the varied conditions of their numerous island homes and continental environments, and to the changes which in the former at least are incessantly taking place—changes which, while they may not be apparent to us, yet are capable of slowly but profoundly modifying the morphological character of all animal and vegetable life. The nominal species which appear to afford the most stable specific characters are—tst, the type form Priamus, which is always large, very melanistic or fairly light in the ground colour of the ?, and with the anterior wing-cell immaculate; but an occasional example will be met with where the cell has a small light patch in it ; whilst occasionally the cell of other forms will possess only a rudimentary mark, or it may be altogether absent, notwithstanding that the rule is for the cell in all those other forms to exhibit a more or less light patch. and, Richmondia, from the Richmond River, Australia, which only differs from Cassandra in being the smallest of the genus Ornithoptera—its variations on the under surface of the ¢ being as numerous as are those of Cassandra, and identical in patterns: in other words that given a special variation of pattern in the larger species, the same pattern may be found in the smaller, a phenomenon that is very suggestive. So that Richmondia is simply a geographical name for Cassandra, only justified by the small size of all the specimens which inhabit the district of the Richmond River. It may be remarked, however, that some very small ¢ example of other species have been met with that are not larger than the average Richmondia, while on the other hand some abnormally large specimens of the 2 of Cassandra may be found in collections. 3rd, Cr@sus. The colour of the ¢ ¢ of this species is very permanent in its character—generally, however, betraying a tendency to become Jess red and more yellow and green in specimens that are bred. As everyone is aware the ? ¢ of the two forms Crasus and Lydius are very distinct—the latter being quite abnormal and acrzoid, and permanently so, so far as our knowledge of it goes. 4th, Uvvilliana is distinguished by the ¢ being apparently always blue, green blue, violet or lilac—though the size and markings—but more especially the scaling of the posterior wings present many diversities extending from the type form to the interesting geographical variety (C@lestis, Rothschild) from the Loutsiade Archipelago. In this latter the light mark in the anterior wing-cell of the ¢ is very fairly uniform in shape and size in all the examples that have been collected. The individuals of both sexes are also smaller than those from other localities, and the colour of the # is very blue. Now the ¢ % of Urvilliana vary to a considerable extent, in depth of colour, from a very light sienna brown to the darkest brown—the light markings present every degree of size, shape, and division that is found in other so-called species of the Priamus group (notably in Poseidon) and they are nearly always large-sized insects ; so that the differentiation from other species is always less in this sex than in the ¢—notably so in the case of the New Britain example of Aruana and Urvilliana. But while all these facts tend to unite the different forms of the genus Ornithoptera (as the author restricts the genus) into one good species, there are other peculiarities of the ¢ ¢ which render the evidence of that unity over- whelming. (a) The general pattern of all the ¢ ¢ throughout the group is really very uniform, especially on the anterior wing, and so is the colour. We have in Priamus, Cassandra, and Richmondia black and green wings (more or less golden green), with a varying extent of black or colour scaling common to all the species of the genus. The shape and size of the green subcostal band, and of the inner and outer marginal green band are always similar—so much so that a tyro, seeing only plain figures of the species is apt to suppose that they all belong to one species. In the three species quoted, the median vein of the anterior wing is not indicated by green atoms or scales; but from, and including Pegasus all the forms are more or less green scaled along this vein and its branches; in a few examples this green scaling becomes so extensive as to encroach largely over the dark area of the wing, and to suggest the possibility that some day examples with the upper wings entirely green may be discovered. In Cre@sus, this scaling is not present ; but it re-appears in Urvilliana, in some examples. On the posterior wings there is generally a discal row of suborbicular black spots, ranging in number from 5 to 1. In the three species named these are larger ; and never probably entirely absent; but in all the other species from Pegasus to Cresus they are generally not so large, or only rudimentary ; and in many examples are entirely absent. In Urvilliana they are sometimes small, varied in number, but generally large, and often fused into the dark scaling of the lower wing. In all the forms this scaling, which is densest at the base of the wings, is generally present, varying in the extent of its area, till it seems to attain its greatest development in some of the examples of Uvvilliana. On the underside of the hind wings of all the species this row of black spots is always present ; the spots are longer than above, more irregular in shape, and always either six or seven in number. Again, (7) on the lower wings of the ¢ ¢ we find in Priamus one, and sometimes more, small golden yellow submarginal inter- nervular spots: these may be between any of the veins, or in any part of the submarginal area ; they may be found, one, two, or more, in examples of most of the species, except Urvilliana; always very small, except in Cresus where they are larger, vary from 2 to 4 or 5. In Cresus and Lydius also there are always 3 or 4 larger silky golden yellow spots or marks in addition—the largest often occupying nearly the whole of the discoidal cell, and a great part of the costa. All these spots and marks correspond to similar more extensive marks on the undersurface, and transmit the light through the wing. When, however, the submarginal group only appears on the undersurface (as it generally does in full number of spots) without the corresponding marks above, the light is not transmitted. But these spots may probably be intended to serve a similar purpose to those semi-transparent spots of nude-membrane found in the genera Doleschallia and Kallima, and the larger ones in the wings of the Heterocerous genera Atiacus, Antherea, &c. These spots and marks are quite analogous to the golden yellow patches and spots on the secondary wings of the ¢ ¢ in the genus ScHOENBERGIA, where they have attained their maximum development ; they also appear as square submarginal spots, fairly large, in AZ THEOPTERA ; but in both genera they are sufficiently distinct from those of OrNITHOPTERA and of each other, to show that the forms of each genus are rightly specialized. Another characteristic of the species of the genus OrniTHopTera is this:—If the ¢ & of Priamus and allied species are examined obliquely against the light, the whole of the green area of the wings—especially the anterior wing—will be seen to be shot with opalescence, golden orange, yellow, and different shades of blue and violet, changing according to the obliquity of position from a pale dead salmon tint to the violet, till no trace of green remains, causing the insect to resemble successively both Cresus and Urvilliana ; and the fresher the specimens and the stronger the light, the more intense will these reflections be. On the contrary if Cresus be subjected to the same positions of light the reflections will be green, so that the insect will appear like a Poseidon or Aruana; Urvilliana only gives salmon or silvery, and slightly green reflections, but a var. exists (a perma- nent var.) Bornemanni, which is really as green as a Pegasus, or a deeper green than a fresh example of Pegasus; it has also the green scales along the median vein, and its reflections make it in a proper oblique position to resemble Cresus. It is found in New Britain, and appears to unite Avuana with Urvilliana, and really might be mistaken for anything rather than a var. of the species Urvilliana. The & of the species Schoenbergia Goliath has lately been discovered, and named Supremus by Réber, and Elizabethe-Regine by a Hungarian entomologist. It is a combination of the characters of Tithonus and Cresus! To those who would group together the forms of ScHoENBERGIA and AZ THEOPTERA it would have been less surprising if it had exhibited a combination of the colour and pattern marks of Tithonus and Victoria. Of the different named forms of the genera ScHoENBERGIA and AZtheoptera it is too early to decide upon the number of species which may ultimately be admitted ; probably many more, at least of Schoenbergia, will be discovered ; and probably ¢ ¢ with short tails and gradations of tail may turn up, and unite Tithonus with Paradisea—judging by the discovery of the ¢ of Paradisea, v. Meridionalis, which is also tailed (and a remarkable tail it is!) and in many ways so distinct from the type form as to justify a full specific rank being given to it. The most extraordinary forms may yet reward those who explore the archipelagoes and the interior of New Guinea. At present the three forms of ZEiheoptera bear, in both sexes, so close a resemblance to each other as to suggest that, while more varieties may be discovered in the Solomon Archipelago, they will only, as Regine and Regis are, be local differentiations from the type Victoria. It therefore remains for the author to indicate the few changes in the classification of the Sub-family Papilionine which are indirectly the result of the arrangement proposed on page (6). As the Papilionide are divided into the two Sub-families Prermv# and Papitionin@ it will be convenient to regard the 2nd sub-family as being composed of a number of tribes, of which Troides would be one. The ist of these should contain the genera Mesapia, Gray ; Calinaga, Moore; Styx, Statidinger; and perhaps Hypermnesira, Ménetries,—a group whose neuration 1s most like that of the Pierinz, in that it has only 3 branches to the median vein of the anterior wings. The second tribe would comprise the genera Doritis, Fabricius; Parnassius, Latreille; Eurycus, Boisduval ; Euryades, Felder; and Liihdorfia, Ersch,—in all of which, except in the first genus, however much they may differ in appearance, at a special period, subsequent to their union with the males, the females exhibit a peculiarly secreted waxy or corneous pouch on the anal segment of the abdomen, which appears to be the result of that union at the time of coition, and the purpose of which is yet involved in obscurity. Mr. Elwes, who has closely studied the Parnassit thinks that the last 4 of these genera should form a separate family, or perhaps he would mean sub-family,—a proposal worthy of considerable respect. It will at any rate be doing them justice to give them the rank of a tribe in the suggested arrangement. The 3rd tribe would include the genera Serecinus, Westwood; Thais, Fabricius; and Armandia, Blanchard. The 4th tribe would consist of the genera, Teinopalpus, Hope; and Leptociycus, Swainson. The sth tribe would be our Trorves, though it would seem that some other genera intermediate between Serecinus and Drurya are needed to more naturally link together the last 2 tribes. The foregoing are suggested, subject to modification, when we get to know more of these genera, and become possessed of the numerous allied species which probably yet remain to be discovered. At any rate the tribe TROIDES will have a secure position, though new forms and even new genera may in the future be discovered and included. (8) The proposed classification would therefore stand thus :— Famity PAPILIONIDZ:, LEAcu, 1819. Sub-Family II., PAPILIONINAZ, Swainson, 1840. Trine 1.

Ree of possibly 2, 3, or 4 genera ;—Papilio Crassus, Cram. ; Pap, Sesostris, Cram.; P. Mylotes, Bates ; Pap. Polydamus, inn. Referring back, in the foregoing table, to Tribe 4, the genus Teimopalpus is made to take its place next but one to the Acreoid Ornithoptera, the Ist genus of the Tribe Trorpns. Of this beautiful genus (only one species of which is at present known) Doubleday, in his diurnal Lepidoptera, remarks that ‘there is little in its structure beyond its long porrect palpi to separate it from Ornithoptera or Papilio, though some of its peculiarities indicate an approach to Thais, a genus in which the palpi are more developed than in any other of the Papilionidze, with the exception of Teinopalpus.” It may be added, however, that the whole form of the head in front of the eyes is more prolonged, being equal in length to the distance from the outer extremity of the eyes to the commencement of the pronotum; but it terminates as a point, z.¢., forms a cone covered with green hairs, the base of which may be considered to be either the front of the eyes or the commencement of the pronotum., The palpi are partly covered by this cone, but in both sexes they project beyond. In the Ornithoptera the palpi are quite concealed beneath the villose tuft which emerges only slightly beyond the eyes. The abdomen in both sexes is unlike that of Ornithoptera in character; the anal valves of the ¢ bear little or no resemblance to those of any of the Ornithoptera, and the red antenne are short and strongly clubbed, similar to the black antennz of the Acreeoid Ornithoptera ; the legs also are altogether shorter in proportion to the size of the insect than in the Ornithoptera. The antennz in their form and length, though not in colour, are most like those of Thais, and the same may be said of the form of the front of the head and palpi of Thais when viewed in company with Teinopalpus. But the body differs from Teinopalpus much more than it seems to differ from the AGArrstip# moths. There is a species of Papilio, P. Antenor from Madagascar, which is remarkable in possessing antennz that like those of Teinopalpus, are brick red, an unusual colour for Papilio, in which these organs are generally black; but they are long, and gradually thickened towards their apex, being like those of the true Ornithoptera, though they often are pointed straight forward, like those of many of the Nymphalide. There are several points of similarity with the Ornithoptera in P, Antenor, suggesting that if it is not ultimately admitted into their ranks, it would have to be placed very near them. The body or abdomen of Antenor is light coloured—an unusual character in the Papilios, but almost entirely the rule among the Ornithoptera, though becoming less stringent in Pompeoptera, and when they reach the Ornithopterina. The annulations of its light abdomen are well accentuated by the same delicate brick red as that of the antenne and of the villose tuft between and in front of the eyes. The anal valves are almost exactly like those of Ornithoptera in form and general structure; and the basal segment of the abdomen is black like the thorax, with the 2nd and 3rd annuli accentuated with black and brick red. In these respects, except in colour, the body quite resembles those of the Ornithoptera. There are many points of similarity between the legs of Antenor and the Ornithoptera ; but the 5th or terminal joint of the tarsus of the former is proportionally longer than in the Ornithoptera. Of course, although the wings and wing patterns seem very dissimilar from those of the Troides tribe, there are some points that are suggestive. Ultimately, it may be, Amtenor will have to be admitted into this tribe, as the type of a special genus ; but at present it will be difficult to say where it should be placed. The author has much pleasure in acknow- ledging his indebtedness to Dr. K. Jordan for first calling his attention to the structure of the ¢ valves of Auntenor, while at the same time expressing his opinion that there were no characters in the genus Drurya that would justify the author in admitting that genus among the Ornithoptera. Though this is contrary to the views of Statidinger, and other of the Continental entomologists, and he still hopes that he has made no mistake, yet the author has the deepest regard for any opinion expressed by Dr. Jordan on the Lepidotera, because of the immense knowledge, morphological and otherwise, which he possesses, with the advantages of being the curator of probably that most wonderful accumulation of entomological material in the world which has its home in the Hon. W. Rothschild’s Museum at Tring. But as every arrangement and conclusion in zoology can, at the best, be only provisional, the author fully anticipates that in the future, when the lepidoptera have been morphologically studied throughout all their families and genera, and their life history entirely unfolded, the whole of our different systems of ciassification will have to go to the wall, and give place to an arrangement that would surprise us all, if we were privileged to be living on earth at that time. Towards this advance in knowledge Dr. Jordan will, if he is spared for a few years, be sure to contribute more largely than perhaps any of us can at present foresee. As it may be thought by some, though no one has suggested it, that the measurements of the legs, wings and other parts of the species described in this work were useless and would be of no value, the author would here observe that though at present there is little prospect of such measurements being of great use, even if carried out ona really exten- sive plan, yet it would be unwise to assume that this will always be the case. The relative measurements of any of the parts of the lepidoptera are not really trivial or useless, though at present they may seem so; every fact is important ; and such measurements may in the future be the means of bringing us valuable knowledge, if systematically pursued by students of this order of insects. In studying the characters of the Coleoptera, for example many species are created and even genera formed almost entirely on a consideration of the relative lengths of the joints of the tarsi, or of the articles of the antennz. To return to the exterior form of the ¢ sexual apparatus, which in the Troides is generally very unlike that of the other Papilionidz, with some few exceptions, it may be briefly stated that the valves are attached to the overlapping edges of the 8th or terminal abdominal segment, and consist of a pair of broad plates of a generally ovoid or semi-ovate shape, and the outline of the whole segment usually is more or less trigonal when viewed from above. They are generally pointed at the end, more especially so in the genus Pompeoptera, where, in a state of rest the point of the (10) right valve sometimes slightly overlaps that of the left. These valves are united to the penultimate segment of the abdomen by fully working joints. It is possible that, while this portion of the abdomen may generally be curved down- ward for union with the ¢, it may be capable of moving in the upward direction also—especially as the ? % of some of the tribe are known to woo the ¢ ¢, as the author has shown in another place. These valves are convex externally, and concave internally: their purpose is to enclose the genitalia, &c. The valves are closed on the exterior with scales similar to that of the body ; their free edges have generally a fringe of hair-like scales, which in some species are denser than in others, and likewise longer: they serve to protect the genital cavity when the valves are closed, from dust or any injurious matter which might otherwise drift in—the fringed edges are in close contact when the valves are at rest; the edges are sometimes slightly grooved without, so that the fringed edges appear to be doubly efficient for their purpose, by protecting a small portion outside the valves as well as in guarding the opening of them. The valves of Aruana and Amphrysus are denesly fringed with these hair scales: Brookeana still more so. Of course as Philip H. Gosse has shewn, there are many variations of form, and structure found even among the Ornithoptera, to say nothing of the other Papilionines. He also suggested a better name for these organs than valves namely oudeos (a sheath or scabbard),. The larve of the tribe Trompes are large, heavy looking creatures, dark in colour generally; their segments are armed with a number of thick, obtuse, sometimes rather sharp, fleshy protuberances, varying probably from 3 to 6 on each segment; and each of the retractile nuchal tentacles is enclosed in an external sheath. In fEtheoptera the fleshy protuberances are somewhat different in colour and shape from those of Pompeoptera ; but more particulars on this subject will be given in the 2nd vol. of this work. Of larve that bear a close resemblance to those of Troipes Papilio diphilus, Esp,, and P. Hector, Linnzus, may be cited. Of the chrysalids it may suffice to say in this place that they appear to bear a very close resemblance to each other throughout the tribe, as the Pupa plate in the 2nd vol. will show. It may be interesting and instructive at this point to bring before our minds a brief description of what the zdeal pattern of the genus Ormithoptera would be; and this will help us to understand how naturally the different so-called species of this and other genera have been able to vary in pattern as they have, and what possibilities there may yet be in store for them, as their environments slowly but surely become modified. The ¢ anterior wings velvety black; a more or less broad subcostal band of green, extending from near the apical angle to near the base of the wings; a narrow band of green along the inner margin from the base to the posterior or anal angle, proceeding from thence up the posterior or hind margin nearly to the apex or anterior angle, but divided more or less in the upper half of its course by the veinlets; all these green marks are softened into the black by green atoms or scales; a brown discal pupiform stigma (entirely a ¢ character) ; the median vein and its branches absorbed in the velvety black of the wing. [Note: The median and other veins with a tendency to become green-scaled; and the green areas of the veins may (and sometimes do) encroach, until perhaps at some future time nearly or quite all the upper wing may become green; but the wing will never become all black. The green is dark originally, but becomes more golden; and forms may be found yet where the golden tone will be so great as almost to eliminate the green in some lights at least ; the green always shot with purple, opal, or fiery orange reflections, when viewed in the right position; the green may and does become intense golden orange or lilac, blue or violet, (or yellow). The pupzform stigma may either be very black, so as to be almost indistinguishable from the black (in which case it exhibits silvery reflections if viewed in the proper position) ora rich red brown, and very prominent. | The under surface of the anterior wing very dark brown; the discoidal cell with a blue-green spot or mark at the lower portion of the distal end, which is of no great extent ; a discal broad transverse band of blue-green, extending from the submedian nervure up the wing to between the 3rd and 4th subcostal nervules; this band is divided distinctly into separate parts by the veins and veinlets and their black borderings, and so divided at its outer third by black lunate marks between the veins as to separate the outer 4th and make them appear as if they were independent green spots: these are always more golden green than the rest of the band. ; [Note: This band may be so broken up as to become a double transverse row of green spots: it does especially soin the Australian Cassandra and Richmondia ; or the black spots may become very small, asin some Aruanas ; the green of the cell may become more extensive, and the entire area of the wing may possibly become quite green, or intensely golden green, or greenish-blue, or golden-yellow green ; but an orange, blue, or red underside is a sunlikely to appear as a blue rose or dahlia in the plant world.| Posterior wings green; a discal row or band of variously shaped black spots parallel with the outer margin 4 or 5 in number; a submarginal black band from the anal angle to the base of the costa; base of the wing above the precostal veins black; a scaling of black atoms from the base, which may spread over the whole wing. [Note: The green colour can vary from an olive golden-yellow to blue-green, blue, purple, violet, and fiery orange ; the black spots may be very large or very small, or obsolete, or rudimentary, or entirely absent, or vary from o to 5; small golden silky submarginal spots may also be present between the black marginal border and the black spots, in numbers varying from 1 to 4; the cell also, and the upper part of the disc, may have golden silky marks, generally of a fairly large size, as in Cresus. The colour reflections of such wings will, when the wing is golden orange, be green. } Under surface of posterior wings green, but golden-green or yellow towards or at the outer margin and the costal (11) margin ; a discal band or row of variously-shaped black spots 7 in number, including the black patch of the anal angle ; the margins all more or less broadly and irregularly black ; a row (between the discal spots and black margin) of golden silky spots in the yellow or yellow-green, and a large cuneiform golden mark or cone with its apex pointed towards the feet between ss subcostal and costal nervures ; the abdominal fold brown, or silvery grey ; the abdominal fringe hght urnt-sienna red. [Note: Even in the blue, violet, or orange forms of Cresus or Urvilliana, the underside will always be green, or a strong greenish-blue, and the green may become so golden as to be virtually yellow in the proper light. ‘The black spots and golden spots may vary from o to 7 each: may be very large, or very small ; the cell may become more or less black. In some ancient forms the row of black disc spots may have been united to the black margin, so as to con- stitute a broad black band occupying half the wing; or the whole wing may have been entirely green on this surface. | The thorax and abdomen vary little from the ideal pattern and colour, which is nearly that of Priamus. ¢. Anterior wings light brown; the discoidal cell immaculate; a broad band or system of discal light spots and marks, so arranged as to present the appearance of a double row of irregular-shaped spots or marks, whereof the 3 uppermost are the longest and largest, these occupy more or less of the whole middle of the disc; no marginal band ; white fringe lunules. [Note: This band may be broken up in every conceivable manner into large or small spots, varying in number from 2 or 3 to 14, 15, or (rarely) 16; even in the acreoid ? of Lydius they are only 17; their form and size may be an elongate-longitudinal. cuneiform, lunate, square, or rudimentary ; or the whole band may be absent, and the wing quite brown all over; the cell may have one white mark or patch occupying only a small portion, or the greater part of the cell, and it may be either sub-tetrahedral, oblique, or exceedingly irregular in shape; it may be divided into 2, 3, 4, or 5 parts; any one of these parts may be absent, or 2, 3 or 4 of them may be obliterated in one specimen, and the remaining divisions may be at any part of the ideal patch: the division may also be rudimentary, 7.e., composed of minute scales, or half-and-half. An Orwithoptera may yet be found with the upper wing nearly entirely white: but this is not very probable ; yet the cell of Lydius is almost entirely white.] Under surface of anterior wing: the white discal band broken up in the same manner as above, but the inner with marks or divisions are longer, larger, and more hastate; the cell immaculate; no marginal band. [Exactly the same may be said of the marks in their variation, including Lydius, as above, except that the cell mark is generally more irregularly shaped and rugged than on the upper surface.] Posterior wings, dark brown; a broad discal band of independent hastate light marks, each with a suborbicular black or brown spot, pupilled faintly with a smaller and blacker round spot; the portion of the light marks below the brown spot warm brown, the margin of the wing darker. (Note: This light band may be very much reduced, partly rudimentary, or obsolete; or extended so as to occupy nearly the whole wing; it may be also continuous except for the veins; the black spots may be deep black; very large or very small; and the marginal band black; the light band may be ochraceous below the orbicular spots, or orange, and the band vary from white and cream-colour to ochraceous. | Underside of posterior wings, subject to the same rules as above, and the pattern similar. [The colour of all light marks may vary from creamy-yellow to a rich orange-yelllow. | Thorax black with a green longitudinal mark ; abdomen ochraceous grey, orange beneath. [Note. No great amount of variation is found in the colour and markings of the body. Except in the case of Lydius, the discoidal cell is always entirely brown. The wings of all ? @ may be any depth of brown from light och- raceous brown, to a very deep melanism above and below.| At the end of this volume, in the article treating of the geographical distribution of the Ornithoptera, the author has endeavoured to convey some idea of the physical conditions of the countries where the species are found. These are naturally very brief andimperfect ; but it appeared to him that in all treatment of such a subject as the geographical distribution of any group of creatures, the more completely the physical and other features of the countries are under- stood, the more likely are many of the zoological problems of the animal world to be ultimately solved; while much light may possibly be thrown upon the subject of which this work treats, even as concerns its more simple points of enquiry. While the author has in their proper places acknowledged his indebtedness to all who have lent him examples of species for study or figuring in this work, he feels especially glad to again acknowledge the assistance he has received by the use of the many splendid examples contained in the wonderful collections of the Hon. Walter Rothschild and Mr. H. Grose-Smith—to which he has generally had access as freely as if they had been his own. The value of this privilege may be estimated, when it is stated that Mr. Grose-Smith’s collection is a singularly rich one, in Rhopalocera—that in the 1500 to 1800 drawers in which his lepidoptera are contained there are representatives of (12) almost all the Ornithoptera, and good series of many of them, almost every specimen being in the finest condition, Of Mr. Rothschild’s collection, in his Tring museum, it is safe to say that in no other part of the world is there such a vast collection of Lepidoptera, especially of the Eastern Papilionidz: that among the Ornithoptera is to be found nearly every known form—and often in such immense series, and representing so many localities, that it may be considered that in this museum alone the materials for any amount of research may be obtained. The Ornithoptera occupy several big cabinets ; and the Papilionide are contained in one large and high room, arranged in 36 big cabinets of 40 drawers each, or 1,440 drawers in all. But the remainder of the Rhopalocerous and Heterocerous Lepidoptera, which is then only a small section of the contents of the Tring Museum, may be numbered by hundreds of thousands of specimens, These and other collections are always receiving augmentation, and are rendered all the more useful by the almost regal library, treating of so many of the Zoological and Biological subjects for which the museum is famous. Finally, the author cannot refrain from expressing his deep admiration and joy in the contemplation of these and the multitudinous works of our holy and glorious God and Creator. The lovely things treated of in this work are but as the smallest portion of the great order to which they belong. A panoramic view of the butterfles and moths of this world would be one long vision of beauty in form, variety of pattern, and delicacy or splendor of colour, illustrated by tens of thousands of species ranging in size from a few millimetres in expanse, to ten or eleven or even more, inches ; their patterns simple in the extreme, or so intricate and complex as to bewilder the eye ; so varied and wonderful in colour as to include every imaginable tint from black or white to dazzling crimson, scarlet, blue, green, pearl, silver and gold; with markings sometimes resplendent with apparently pure gold, silver, copper, or aluminium, and the colour and flashing of all precious stones—prismatic, silky, velvety, diaphanous, quite transparent, intensely white, or intensely black, or ivory-like ; with colour reflections in the most unexpected places; with changes of colour according to position of so wonderful and startling a character as to be fairly amazing ; there are combinations of colour hardly dreamed of by the artist, yet so beautifully harmonised as to create astonishment in any sensitive mind; these most wonderful keys of colour, metallic texture, and brilliancy, are not confined to the larger forms, but are just as commonly met with amongst the most minute ; and with all this glory an extraordinary variation of structure of the legs, palpi, and antenne, and of imitation or mimicry in the shape of the body, characters, or pattern of wings, and simulation of the appearance of very distantly related species, as well as of other objects and other orders of insects! Some or other of these glorious things are to be found living in all climes and at all altitudes, from far within the Artic circle to the Equator, and from sea-level to 18,000 feet of mountain height! A truly royal Divine gift to the earth is this one order of animals alone! But the glory of it all is that we only begin to dream of the wealth of creative wonders and beauties as we contemplate these. ‘here are the Coleoptera, often with even greater glories than are to be found among the Lepidoptera, and a diversity of shape and general structure almost absolutely inexhaustable ; with varieties of life habits that are endless—some graceful in the extreme, others bizarre and almost monstrous in appearance, their horns, and armatures, and tusks, as strange in structure as those of deer, elks, rhinoceri, elephants, or any of the African horned vertebrates—these characters being generally confined, as in the vertebrates, to the male sex; some are covered with spikes, or look like thorns when at rest; others have long antennz with brush-like appendages; some resemble winged seeds, or the flat seeds of certain plants; or they are spherical, tortoise-shaped, hispid, cylindrical, and a multitude of shapes beside; their shining wing cases (elytrae) are often more gorgeous and brilliant than gems or metals—some of the Lamillicornes look as if sculptured in polished brass that is lighted by electric light—and many of the Phytophaga when alive are like spheres of sunlight, or dazzling dewdrops in the early morning—as the author has seen them in the tropics ; some are apparently small nuggets of gold, silver, copper, iron, or other metals (in the genus Chlamys), others are like gems—sapphires, rubies, emeralds ; some, when viewed with the eye appear to be encrusted with emeralds, and under the microscope their wing cases look in parts like mountains and valleys of precious stones, heighted in beauty by the art of the lapidary; some at night have points behind the eyes blazing with phosphorescent light ; others, as they fly, look like a waving mass of fire-flakes,— as the author has seen them among the dark, feathery palm trees on a moonlight night in New Granada; and yet others seem to emit fire from every joint of the armour encasing the under side of their bodies. Beetles are so subject to mimicry among themselves, and mimicry of other objects and orders of insects, that we continually meet with the strangest examples of this phenomenon. Some are so small as to be scarcely visible to the eye; others so large that a pair of them would require to be accommodated with a fairly good-sized box ; they are found in every land, and every position in and out of water: active in darkness and light—in manure, in flowers, in forests and on plains, under stones, in caves (and therefore blind), under the bark of trees, in the heart of timber, in ants’ nests (and then shaped like ants) ; mimicking spiders in form, and probably with some of their habits ; like long bits of stick among dead branches ; flying in the air in clouds, or so few in individuals as to always remain rare; so numerous in species that more than 120,000 must have been described, besides thousands of species yet to be named, and multitudes of new species coming every year from various countries. And so we may pass on from order to order of insect life, among the Orthoptera with their multitudinous strange forms of Hemipterous (or bug life), with species as gorgeous in colour and wonderful in shape as beetles; of locusts, often with huge upper gauzy and decorated wings, and splendidly coloured under wings, which in a state of rest are folded like the leaves of a fan, and concealed beneath the upper ones; or the many species of Mantis, with their hypocritical-looking attitude; or the walking-stick insects, some of them 24 inches long, and most like a lot of brown, or mossy, or lichenous twigs arranged in the form of an insect, and the other curious manifestations of the Phasmide, or phantom-like insects, or the still more remarkable leaf insects, of which there are many species. All through this great order we meet with wonder upon wonder! and so we do in every other order, whether as regards form, function, size, or colour. But should we depart from the insect world and review either the other Arthropods, or indeed any of the Invertebrate orders ranging from spiders through the almost endless armies of other creatures, down to the diaphanous Medusz of the ocean we shall experience the same overwhelming sense of the vast array of creatures often strange and beautiful in colour and decoration with which this earth is peopled. We should review the spider tribes, with species most tiny and species as (13) large as birds; ferocious in aspect, or gorgeous in colour and markings, some banded with pearl or silver ; or with delicate patterns traced on their bodies in gold, crimson, or scarlet on a green or a brown ground. There would be the Mollusca with their glorious shells—painted in all tints of colour—adorned with wonderful surface designs moulded in classic shapes, with many of them strangely spined, such as are some of the Muricide, Cardiums, Veneride, Chamas, or Spondyle ; the cylindric and pupzeform clawsilias and other genera, the lovely Bulimi and Helices, the rich Volutes, Cones, and Cyprias, the gorgeous Tvoche, Haliotide, and Telling, and the numerous Unios with their pearly or silvery interiors! Then descending lower still to the world of semi-invisible creatures, such as the Radiolaria, Polycsystina, Diatoms, and khizopods, to say nothing of others lower down still, so small, yet so complex and beautiful in their siliclous homes.and shells, or so simple in their organisation, till we seem to be entering within the portals of the infinitely little,—where species even of the Radiolaria, more astounding in form and complex sculpture than anything among the higher groups of creatures come to our notice in such multitudes of species that Haekel describes in one of the 48 huge vols. of the Challenger Report between 4,000 and 5,000 of them, not half of those known to exist—with the additional wonder that however complex the sculpturing and pattern of each species is, it is all executed within the space of a minute point that seems to have no dimension at all ! We may truly and reverently say that all God’s works are fearfully and wonderfully made! and we may add that God sends out all His creatures well and beautifully dressed, and also efficiently armed for the warfare of its life. This is exemplified through all the Vertebrate and Invertebrate creatures of this globe, from the fearful beauty of the Reptilia, and the graceful beauty of the countless species of Rodents and Birds, till we reach those magnificent members of the ereat Cat family—the tigers, leopards, and other big beasts of prey. No living mind can sum up all the Creator’s works which people and adorn the beautiful world in which we live. Ages of investigation are needed for such a task as this, and then perchance new creations would be in progress. Yes, and then? and then ?—there is infinity—space with its worlds and suns visible to the telescopic and photographic eyes, to be counted by millions without limit—system beyond system, universe beyond universe, above, below us, and in every direction of space, east, west, north, or south, stretching away on the pathways of infinitude for ever and for ever, without beginning or end! But is this all? No! a thousand times, no! For then even, we may be sure that while this is only the visible or material universe, there is an unseen—a spiritual universe, which is still more vast, more wonderful, more complex, and more glorious! Aye, and a boundless universe of Intelligence more won- derful and beautiful than all; while every being, every mind, every force, and every manifestation is subject for ever and ever to the ineffably holy, wise, lovely, and awful power and will of the Triune Love—the being whom we call God, who is the author of all, and who reigns over all. And here we must rest, with the joy in our adoring hearts expressed by those words of the Psalmist David: “Many, O Lord my God, are Thy wonderful works which Thou hast made, and Thy thoughts which are to us-ward ; they cannot be reckoned up in order unto Thee: if I would declare and speak of them, they are more than can be numbered.”* Yet ‘‘ We will speak of the glorious honour of Thy Majesty, and of Thy wondrous work.”+ And “ All Thy works shall praise Thee, O Lord; and Thy saints shall bless Thee.” { *Psalm xl., 5. {Psalm cxlv., 5. tPs. exlv., 10. David, or the Author of the 148th, 149th, and rgoth Psalms might well call upon everything in creation to praise the Lord! The sublime words of these ancient Israelitish Hymns come to us now as the fitting expression of a mind overwhelmed with the contemplation of the radiant glory of the King of Kings in the endless manifestations of His thoughts in Nature, History, and Providence!

Vol. I. ii. OBSERVATIONS ON SOME OF THE FOREGOING FIGURES. Fig. 1.—On comparison a considerable difference ob- tains in the outlines and character of the neuration of the different genera of the great family of Papilionide. In our Fig. of Ornithoptera, drawn from the ? as being the most useful for the purpose, attention may be called to the 3 accepted branches of the median vein on the anterior wing,—their direction being normal in the 2, while in the ¢, as shown in another place, they are considerably distorted or diverted in their course by passing through the disturbing medium of the stigma or sexual brand. This effect is necessarily produced on both surfaces, because the brand is impressed on the two membranes of the wing: and throughout the whole of the species or forms of the true genus ORNITHOPTERA among the 3 éthere is no exception to this rule. It willalso be ob- served that the wing outlines of the female ORNITHOPTERA differ from those of the males so considerably in every species that if we were only just made acquainted with them, and each sex had been taken in a different district orisland, we might have been disposed prima facie to regard them as members of two distinct genera. It may be observed that the males are always closely related in appearance and splendour, as if they were only local forms of one species, with the single exception of the Australian Richmondia, from the Richmond River: [even this species is as splendid as any of the others, but it is much smaller—appearing more like a dwarfed form of O. Cassandra;| and that the females also are generally much alike in dull colouring and mark- ing, as well as size and outline, with one exception (that of Lydius) though varying so infinitely in minute details, that they also might well be regarded as local variations of a single form, The two sexes of the PoMPEOPTERA, on the other hand, generally bear a close resemblance to each other both in outline and colouring, and even, with a few exceptions, in size,—the most notable being P. Dohertyt ; there is no disturbance of the veinlets of the # anterior wings, because the stigma is absent, and an abdominal marginal pouch, filled with Azdroconia, takes its place. By a natural gradation the South aud Central American red and black, and green and black Papilios (or as I pre- fer to consider them, OrnrrHopTertina, follow with a similar outline of upper, and sometimes a tailed posterior wing; but inno known case is the hind wing of ORNI- THOPTERA, TROGONOPTERA, Or POMPEOPTERA, thus pro- longed. In TroconopTErRA, like PoMPEOPTERA, the form and appearance of the sexes are very similar, and the 3 proves its close relationship to Pompeoptera by the abdominal fold or pouch, with its contents. The outline of the genus is not unlike that of Druryia, which we consider as the head of the group of the Ornithoptera, though the anterior wings of D. antimachusare more concave, we might say, almost falcate. DRuRyIA (including the West African O. Zalmoxis), appears to differ but little in the wing outline of the sexes, except in size; and being Acrzeoid in superficial appearance, recalls to our attention the Asiatic Papilios of the Disszmilis group. But the most remarkable of all Ornithoptera, not excepting even the A2THEOPTERA, is the genus ScHOENBERGIA. Here we have a tailed hind wing, almost suggestive of that of the genus Leptocircus (of Swainson), with a curious arrangement of the neuration to strengthen the modified parts, and a disproportion between the size and form of the anterior and posterior wings,—the body also being modelled on a modified plan. In an examination of the true Papilionidz we meet with several interesting resem- blances to the neuration of the s Schoenbergia. The females of the latter genus are outlined like those of OrNITHOPTERA, and the neuration is closely like that of the ¢ A=theoptera; the general appearance is something like that of OrwirHopTeRA, though darker and in an inde- finable way considerably distinct ; but it is very closely like the alleged ? of Sch. Tithonus,—while the general appear- ance of each, is unlike that of the species of Attheoptera. Lastly the males of A) THEOPTERA possess a stigma or sexual brand, the 3 median veinlets are very close together and low down on the wing—are modified in direction by pass- ing through the stigmatic surfaces—and the excised outline of the posterior wing is absolutely abnormal and curious; added to this the splendour of the insect is greater than that of any other known species or genus of Lepidoptera, not excepting even those of Morpho, Callithea, Agrias, or Urania. A review of other sections of the PAPILIONIN#, with respect to their outlines and neuration, including the genera TEINOPALPUS, SERICINUS, ARMANDIA, Tuars, Euryapes, Eurycus and Lueaporria would yield much interesting and instructive material for comparison with the Ornithoptera. In all these genera it may be noticed that the precostal nervure is bifid, though the size and shape differ much in each genus; while in the genera Doritis and HypermnestrA this is not the case—a fact which seems to ally the latter to the sub-family Prerina, though the median veins of the anterior wings are four- branched as in Ornithoptera and Papilio. Fig. 2—The Tegule or Paraptera are affixed at the base of the anterior wings on the upper side of the _meso- thorax, or second section of the thorax. In the Ornithop- tera they are large and usually covered with black hairs ; but in some Lepidoptera they are often of different colours from the rest of the Mesonotum, or with spots of two different colours as the case may be, as in the Heliconia, Danaine, some of the Papilionina, and the Arctiidz among the moths,—the American arctiide for example. In some genera they are obscure in outline, as in Par- nassius, some of the Geometride, and in other families; while they are very prominent and recognisable in the Arctiide, the big Bombyces, some of the Geometride, and many butterflies; but their most obtrusive develop- ment is met with among the Noctuidz, notably in the genus Plusia, where they raise the thorax into an absolute ridge near the head ; and, as Westwood points out, in the genus Cucullia ‘they are very large, and push forward the thorax, so as to forma sort of hood over the head.” I may, however, add that in the latter case this elevation is really the result of the large size of the patagia or tippets which are placed at the sides of the pronotum, and are more prominent than in any other genus which I can call to mind at the present moment. In the genus Xylina the paraptera are elongated, and give the sides of the thorax an elevated appearance, with the centre depressed. But perhaps the most lovely and interesting modification of this character is to be met with in the European Angle- shades moth, Phlogophora meticulosa, where the Paraptera fold gracefully down the sides of the mesonotum in the usual way, with a triangular elevated mass of hairy scales with two preater lateral prominences, and a smaller one below on the metanotum. The patagia cover nearly the whole of the pronotum above, have a small central promi- nence, and are ornamented with delicate curved lines to look as if there were 6 patagia instead of two. These wing covers if viewed from their under surface (see fiz. 17), appear to be very convex, and on the underside evidently possess a complex organism if we may judge by the multitudinous divisions of the thin membrane, and the cellular appearance under this membrane. It is evidently a highly organised scale, adhering to the base of the wing only by a very small portion of its surface ; is thick and somewhat corneus, probably with more than one thin membrane beneath, or even several lamine, and always clothed above with long hairs, which extend beyond the outline of the paraptera itself, often to a 5th or 4th of its length, The form of these organs is pretty constant in the Ornithoptera; but varies very much throughout the Lepidoptera; their office seems to be to cover the muscles and veins at the base of the wings, for decoration, and probably as a protection in some way to the breath- ing organs. The shape of this scale does not appear to differ materially in the two sexes. We are indebted for the different names applied to these organs to the following authors: Pterygodes, Latreille; Paraptera, MacLeay ; tegule, Kirby and Spence. Fig. 4.—There would seem to be some uncertainty in the way different authors regard the number of the seg- ments of the body orabdomen. In this fig. it will be seen that on the right side I reckon 7 segments, including the caudal or anal extremity. No. ‘‘6” and ‘‘6f.” in the fig. only represent one segment, as ‘‘6f” is only a prominent fold o that segment. On the left hand side of the figure a small section at the base of the meta-thorax is hypothetically numbered ‘‘1?” and so on with the others down to “8?” but a careful examination of the part with the microscope appears to make it a continuation of the meta-thorax, coming just below the scutellum; though it probably is only a folded portion of what on the right side I call the rst segment. In fig. 5, representing the ¢ abdomen, there are 8 annulations, including the anal segment: on the left hand side, they are numbered from ‘“‘r?” to ‘*g?”. Here, by a reference to figs. 8 and g, No. “1?” in each case appears to be a distinct segment; but it is by no means certain that they may not be a small portion of the meta- thorax. One thing is evident, the abdomen of the ¢ of ORNITHOPTERA consists apparently of one more segment than that of the 2. Figs. to and 11.—The shape of the parts of the face below the villose tuft of the head appears to differ some- what in the two sexes; but the labial palpi are similar in form, though very different in the relative length of the iil. joints from those of other genera, especially in that of Drurvyia, Papitio, and Srrecinus. The Palpi are very short, and are entirely, or nearly entirely concealed by the dense mass of hairs, which partially also conceals the spiritrompe when in a state of rest. Fig. 13.—The slender proboscis called by Latreille Spiritrompe, or Spirignatha, (the latter name corrected by Westwood to Speirignatha), Antilla by Kirby and Spence, Liagua by Fabricius ; and Haustellum by general authors is composed of two separate pieces, the analogues of the maxilla or lower jaws of other orders of insects. These two sub-cylindrical tubes vary greatly in length in the different genera of the order. The junction of the two is effected by a series of minute ducts (inoscula) or hooks which link them together, thereby forming an intermediate or central tube, through which the juices of flowers or carrion, and the moisture of way-side pools, or the dew on vegetation is conveyed to the mouth. It has been supposed that the lateral tubes are for the reception of air, but this cannot be established. At the base of these a pair of relatively minute palpi is to be found (Fig. xiv.), which in the Papilionidz are generally hidden beneath the hairy scales round the mouth. These spiral maxillz are defended by a pair of longer palpi clothed with scales, which are situated on the lower lip. This beautiful organ is intended for the extraction of the nectar from the bottoms of flowers; and, when at rest, is spirally folded up, and nearly hidden. Its greatest development in length is probably among the Sphinx or Hawk moths. The magnified section (Fig. 13, Ba.2) will give some idea of its structural beauty. Figs. 15a, 15b, 15c.—Are an endeavour to give the true shape of each section of the thorax as seen laterally. It may be mentioned that the Protheracic and Metathoracic sections are moveable, the mesothoracic being much the largest, and morerigid. It is possible to move the Pro- thorax as easily as the femur of the anterior leg—indeed in general appearance it is not unlike the femur, only rather broader. In each section the femur sinks into a groove when at rest, and inits normal position. The anterior wings are affixed at their base to the mesothorax, and beneath them in the space (B 2), is generally a mass of coccineus hairs, beneath which evidently are the spir- icles or openings of the organs of respiration, which as we know, ramify through the whole of the organisation on a dendritic plan. The posterior wings are also attached at their base to the metathoracic section (Fig. 15c). As in all insects each pair of legs is affixed to its respective sec- tion of the thorax ; the first and second pair being nearer together, and the third pair further removed. Fig. 16.—Represents the legs of the typical Ornithoptera. Very slight differences may occur between those of the dg and ?; somewhat greater obtain between those of diff- erent genera, as may be observed by reference to other plates in this work, especially in the character and relative lengths of the tarsi of the anterior legs. The ungues or tarsal claws are in Drury1a longer than in ORNITHOPTERA, or something like those of Papitio, though more like OrNITHOPTERA in the form of the base. But as a matter of fact the form of the ungues varies consider- *This segment of the thorax is usually the largest and most highly developed as well as complex of the three in all orders of the Insecta; but it attains its greatest size in the order of the Diptera, where it forms the principal part of the thorax. The reason for this can be readily understood when we consider that to the mesothorax are attached the 2nd pair of legs, and the pair of anterior wings. iv. ably throughout all the genera of the Papilioninz, and indeed throughout the whole order. The legs, consisting of the 5 chief divisions, are each united to the sternum of their respective Thoracic segment by the coxa, which articulates with the sternum, the form being variable in the different insects, and even among the various divisions of the lepidoptera. The tibia, which is generally equal to the length of the femur, is often, but not always, armed with a pair of spines or spurs, at its junction with the tar- sus. In the Ornithoptera these appendages are some- times absent from the anterior legs, which, however, always possess a thickened spine, or hollow cone midway affixed to its underside. All the divisions of the tarsus at their articulation possess a pair of spines slightly longer than the numerous spiny hairs that fringe the entire length of the tarsus, and more sparingly (in rows), of the tibia. The divisions of the leg may be reckoned as ten in number, including the ungues (see fig. 16, xxx, A—G). Fig. 17.—The antenne generally possess from 44 or 46 to 50 and 52 articulations, ranging from the scapus (or the 1st and most conspicuous joint, which is implanted in its torulus, a cavity of the head between the eyes, and close to the eye) to the more thickened apex. But in ORNITHOPTERA, as in the diurnal and many of the heter- ocerous lepidoptera these articulations are not flexible; though the antenne are always more or less curved, espe- cially outside of the Nymphalide. i erour 7 ACRAROID ORNITHOPTERA. iv*.
