In presenting volume iv of this work to my brother-lepidopterists, I do so with some misgivings, due to the fact that, whilst it has been passing through press, Messrs. Rothschild and Jordan have issued their large and excellent work, 4 Revision of the Lepidoplerous Family Sphingidae, and have, as it were, thus brought my own limited attempt into rather poor comparison with their own wider and more comprehensive work. ‘The scope and aim of the two books, however, though dealing more or less with the same subject, are so widely different, theirs being distinctly systematic and mine essentially biological, that one, perhaps, may he considered as more or less supplementary to the other. It has been a matter of great satis- faction to find that, in many instances, where my collaborators and I had found it absolutely necessary to make new and marked changes in the groupings of certain of the species, Messrs. Rothschild and Jordan have, quite independently, made the same changes, with the result that we found ourselves most unexpectedly in agree- ment with these authors on almost all points in which we had expected to encounter hostile criticism and opposition from the more conservative workers at this interesting superfamily. This, in itself, is satisfactory, and, if the British lepidopterist finds that the British species, which our immediate lepidopterological ancestors have lumped together under the generic names of Dezlephila, Choerocampa and Sphinx, have, in most cases, not only been placed in different genera, but, in some instances, in different tribes, and even (in the case of Daghuis nerit) in a different subfamily, we can only urge that we are sinning in good company, and that a critical review of the Sphingids of the world has proved, quite independently to Messrs. Rothschild and Jordan and to ourselves, that the few British species, included in these genera by Stainton, Newman, Barrett and Meyrick, are really scattered representatives of widely different groups having their central areas often in districts quite outside the limits of the Palearctic area. We feel quite satisfied, therefore, with our results in this direction. There is, however, one point of difference between these authors and ourselves which is most unsatisfactory. This is the difference in the results arrived at in our attempts to grapple with the question of generic nomenclature. Whilst they and we both claim to have been guided by the strict law of priority in this matter, we have arrived, in many cases, at totally different results, and, whilst we are agreed for example that gad/zz, should be, by the strict law of Vi. PREFACE. priority, called Celerzo gallit, populi—Amorpha popult, tiliae—Mimas tiliae, and so on, yet Messrs. Rothschild and Jordan term the species we call Hemaris fuciformis, Haemorrhagia fuciformis, the species that we call Sesza stellatarum, they know as Macroglossum stellatarum, and these differences are only typical of many others. These divergences arise from three causes: (1) The entirely different way in which we select the types of the various genera. (2) The subdivision of certain genera by one held to be inseparable by the others. (3) The rejection by these authors of Hubner’s Zenéamen, which they urge contains only ‘‘nomina nuda.” Their mode of selection of the type of a genus is easy if not scientific, for they consider the species placed in the first position in the genus by the author, the type, whether or not such species agrees with the diagnosis of the genus, or whether the species was or was not known to the author. There is much to be said for this mode of selection of a type, for the most ignorant lepidopterist can do it as satis- factorily as the most learned, it does away with the need of either knowledge or brains, and the type-fixer need not determine which species of the genus were really before the author when naming the genus, nor which species were afterwards added by him as possible members of his genus from descriptions or the examination of the figures of other authors, the species being unknown to him in nature. Neither does he need to trouble himself about the action of the original author’s successors, nor consider their work. By this amazing method ocel/ata becomes the type of Linné’s genus Sphinx, although Linné himself shows us that he obtained thename from Réaumur and intended it specially to apply to Zzgustvz, ‘The ‘*‘ Merton Rules” insist that the ‘“‘ type” of a genus must not disagree with the description of the genus, and shall be considered as that species on which the generic diagnosis was essentially or mainly basea, so far as is compatible with an acceptance of subsequent revisions, in their chronological order—which is the only true “law of priority.” This appears to us both sound logic and commonsense. It requires, of course, in most cases, knowledge and _ intelligence to settle these points, and it follows that the type can only be determined by those who know. It is true that the fixing of the type by this means is not automatic, it may lead to difference of opinion and, therefore, has drawbacks. Without wishing to defend the method adopted further, we will only add that, with the publication of the ‘Merton rules” we had hoped that the workers at the British Museum and our leading lepidopterists would have been guided by their principles and a large measure of uniformity attained. Vain hope! Every lepidopterist who has reached a certain standard of work, knows how to construct rules that shall lead to uniformity better than every other lepidopterist, and the result is that almost everyone has his own independent method. ‘To us the whole matter appears egotistical; at least the leading British workers could readily agree to an uniform code, but, evidently, whilst everyone cries aloud for an uniform nomen- clature, the criers take every possible precaution not to get it. Those differences that arise from a subdivision of genera, the natural outcome of a close study of the species involved, are of much less importance, for they are largely the- result of the PREFACE, Vii. personal predilections of the author, ¢.g., we maintain the /yles (euphorbiae) group as generically distinct from the Celerio (galliz) group, &c., but such differences are readily dealt with as they involve no real divergence of practice by the authors. The question of what have been termed generic ‘‘nomina nuda,” Ze., generic names without description, is on quite a different footing. Hibner, in 1796, figured populs, as Sphinx popult. In 1806, he published a scheme of classincation, known popularly as the Tentamen, one of the original copies of which is in our possession, and an exact verbatim copy of which is published in the Lxdom. Record, &e., xiv., pp. 167-168 (and which he afterwards worked out, with modifications, in his other works at length), in which, among others, he proposed Amorpha as the generic name of fopulz, Manduca as the generic name of afrofos, &c. To assert that Amorpha is a “nomen nudum” appears to us quite untenable since it was defined by its reference to fopuli (already figured by the same author) as the type. It appears to us to be a much more clearly defined generic term written simply—Amorpha populi—than does Linné’s Sphinx defined as—‘‘ Antenne medio crassiores s. utraque extremitate attenuate subprismatice. Alz deflexe—Ocella/a, populz, tiliae, nerit, convolvult, ligustrt, atropos, celerio, euphorbiae, tantalus, stella- tarum, culiciformis, filipendulae, phegea, statices,’ and many other hetero- generic species. Our authors say that ‘‘ Every name is a term for a definition.” If this be so, is the name Amorpha less satisfactorily defined by simply citing popul7 to it, than is Sphznx, described in such a way that atropos and statices are included in it? The fact 1s, the names of the older authors must be used with commonsense and in the light of our knowledge of the work of the authors; the work of Linné shows us that he looked upon /gustri as the typical Sphinx, we know that Hubner looked upon fopulz as the typical Amorpha and atropos as the typical Manduca. ‘This excursus will perhaps be held by some to form an excellent illustration of the rapid approach we appear to be making to an uniform code of nomenclature that shall be accepted by all lepidopterists ! To meet the criticism offered on our last volume, that we had ourselves in some cases used generic ‘“‘nomina nuda,” and that descriptions of these were advisable to save them from being sunk by those who disagreed with our action in using such, we took steps to have this matter rectified by describing them in the February no. of Zhe LEntomologist’s Record, 1903, pp. 42-43; whilst, as it had already become necessary to found and use new generic names in our progress through the present volume, these also were described in the March and April numbers of the same magazine (op. cit., pp. 75-76, pp. Ioo-101). About a week after the latest of these descriptions had appeared, the Revision of the Sphingidae was published, when we found that we had unknowingly and unfortunately forestalled some of the new generic names that Messrs. Rothschild and Jordan had therein created, ¢.g., Clarina, Tutt, Ent. Rec., xv., p. 76 (March 15th, 1903) forestalls Berutana, Roths. and Jordan, Revision, &¢., p.519, April 21st, 1903), etc. One or two others are in like case, and our names must in these instances stand. In that part of our book (from p. 297 to end) printed after the publication of the fevision, we have, of course, utilised Messrs. Rothschild and Jordan’s Viil. PREFACE. new genera wherever available. There is one point in particular, out of many others, in which the work of these authors far> surpasses our own, and that is in their mode of treatment of the variation of the species. Their own immense collection, the visits paid by Dr. Jordan to all the leading collections on the continent, the loan of types from out- lying countries, &c., have permitted them to attempt to deal with this phase of the subject on general biological grounds, and, in some cases, they have thus been enabled to discriminate between the “literary”? type and the “ biological” type, and, having determined the latter, so far as the material allowed, have arranged the various forms round it according to their assumed phylogenetic connection therewith. For ourselves, our material has been too small and our knowledge too limited to enable us to attempt anything so extensive. Nor must we forget to draw attention to _ their comprehensive scheme for separating the various forms, but their reasons for changing the well-known term “aberration” to “individual variety” and ‘‘variety” to ‘“‘subspecies” appear to us altogether unconvincing. To assume that, because ignorant and careless lepidopterists make an erroneous use of existing terminology, reason is shown for changing the terminology, appears to us unwarrantable. In our more ignorant days we misused the terms variety and aberration, over and over again, and main- tained this misuse throughout the whole of our work, The Aritish Noctuae and their Varieties, but to assume that a _ different terminology would have abolished our ignorance is at least open to question. Other points arise out of this view of our subject, one of which is that in which these authors gird at those who, like ourselves, have adopted the Superfamily, Family, Subfamily, Tribe, Genus and Species, as the various group names for classification. They claim that these are too numerous, that the Family and Superfamily should be united as the Family, and the Subfamily should be the second term of the series. It is humorous, however, to find them calling the Superfamily Sphizngides the Family Sphingzdae, then dividing their Family into Sections A (.Sfphingidae asemanophorae ) and B (Sphingidae semanophorae) and subdividing A and B in due course into subfamilies. The fact is that their method differs in no respect from ours; it is only a matter of terms, in which the classificatory categories compare as follows: Superfamily Family Family Section of Family Subfamily Subfamily Tribe Tribe Genus Genus Species Species Variety or local race Subspecies or Geographical variety Seasonal variety Generatory variety Aberration Individual variety The authors claim simplicity for their method (2nd column) over ours (1st column); we can only urge that if their method is the more simple it is less lucid. We are unfortunate in not even seeing its claim to simplicity; for ourselves, it looks much like putting a premium upon ignorance. Unfortunately, human PREFACE. ix. ignorance is rarely, if ever, convinced with anything that attempts to lead it by easy stages to a higher level, and we have little hope that the entomological collector will be raised to a more exact method of description by calling a ‘‘ variety” a ‘‘ subspecies,” an ‘ aberra- tion” an ‘individual variation,” a ‘‘superfamily” a “family,” and ae tamaily << Section A or BZ as the case may be. Nor do we see the reason for the alteration of the generally accepted tribal termination ‘‘idi” for ‘‘icz,” a change that makes neither for greater uniformity nor simplicity. With their sinking of the ‘ subgenus” we quite agree; if it is to be held, as they (and we) hold, that “the genus is the classificatory unit one category higher than the species and com- prising one definable group of species,” then a subgenus has no place ; in its present use by authors the subgenus replaces the genus, the genus the tribe, and so on, the result simply being an application of terms to groups differently called by almost all other biologists, and hence making for confusion. These are the main points which a careful study of Rothschild and Jordan’s magnificent work suggests to us are in need of explanation, showing how the differences between their work and ours have arisen. The wisdom of sinking a large number of well- differentiated, and what have hitherto been held as clearly distinct, species as varieties, is not for us to judge; we have insufficient knowledge to deal with the matter. It will be seen that the arrangement of our ‘‘ Catalogue,” at the ena of this volume, differs considerably from the order adopted in our work. During the progress of a work of this magnitude the author is always having, as it were, to consider fresh facts that modify his earlier judgments, formed on less material, and to make this change clear to his readers. In fact, he educates himself by his work and is really only fitted to commence the writing of his book Meine concludes data Tf one cared out this’ © mental attitude to its logical conclusion one suspects that no book would ever be written, for, as it is a plea for perfection, and nothing perfect from this standpoint can exist, it follows that each successive stage of work would only lead to the desire for a better. This is only put forward as a plea for lenient consideration of the many imperfections and illogicalities that will be self-evident to every serious student as he follows our work, and as a means of adding that the order of the Catalogue, so far as a linear order means anything, represents a some- what maturer view than the order of the book itself. To my collaborators, I desire to express my unqualified thanks —to Dr. T. A. Chapman, Messrs. A. W. Bacot, W. J. Kaye and L. B. Prout my very best thanks are due. The references to their work will show how greatly I am indebted to them, whilst the kind help of Messrs. G. C. Bignell, C. R. N. Burrows, J. C. Dollman, W. F. Kirby, A. Sich, and others, must not pass unacknowledged. I had hoped that the book would have been published some months since, but various contingencies, mainly relating to printing, have delayed the work till almost the end of the year before completion. Still, I trust now that it is completed, it will meet with the approval of all those serious students of lepidopterology who are generous enough to support my work. It has been continually urged, by Mr. Bateson and others, since xX. PREFACE. the publication of the rst volume, that an extensive ‘‘ general index ought to be printed in addition to the long “special” index provided with each volume, to make the contents more readily available to the generalising biologist. In response to our offer in the preface to volume ii to print such an index should any lepidopterist be willing to compile one, our friend the Reverend George Wheeler, M.A., kindly offered to do so and we have great pleasure in adding his excellent contribution to our work to this volume. We have no doubt the labour involved will be fully appreciated by those biologists who use the work seriously. Whilst we regret that our subscription Jist meets with no better support from the British lepidopterist, who appears often to be unwilling to extend his knowledge in the direction indicated in these volumes, we have to thank that ever-increasing number of supporters who purchase the work through the publishers and with- out whose active aid the publication of the work could hardly be seriously persisted in. At the same time we do most heartily thank those who do subscribe and thus enable us to produce a work which even the Continental lepidopterists recognise has a much wider scope than its title would indicate, and which it has already been suggested in the German magazines should be translated into that language for the use of German lepidopterists. One cannot believe that a work, essentially British in its conception and main outlines, can be of greater value _ to German lepidopterists than to those for whom it has been primarily written. We trust that all those who have the work will find as great pleasure in studying it as the author has had in writing it. The subscribers who have been added to our list since the publication of the last volume are :— Bayne, A. F. James, Russell E. Broome, E. G. Lambillion, L. J. Chamberlain, (Miss) M. Leicester Corporation, The Colthrup, C. W. Oberthiir, Charles, F.E.S. Dyar, Harrison G., Ph.D. Prest, E.E.B., M.A. Federley,: Marry Redmayne, Mrs. Gillmer, M. Wesley & Son (6 copies) The knowledge that no one man can bring to a successful issue so comprehensive a task as the completion of this work, leads us to state that, if any well-qualified lepidopterist with sufficient leisure feels inclined to prepare any one of the proposed future volumes, on the same lines as those published, we should be pleased to hear from him. It might be possible for us to collaborate and to take the responsibility of publication of such a volume (or volumes) and we would suggest that the Tortricids, the Noctuids, the Adelids, the ‘Tineids (27 sens. strict.), Pyralids, Crambids, and Geometrids are among the groups a thorough overhauling of which is highly desirable. PRESS NOTICES OF VOL. III. ‘* Nous venons de recevoir le troisitsme volume du grand ouvrage de J. W. Tutt, sur les Lépidoptéres Britanniques, A Natural History of the British Lepidoptera. Ve succés obtenu par l’apparition des deux premiers volumes a été tel que le troisiéme était attendu par tous les naturalistes sérieux avec une vive et légitime impatience. L’attente n’a pas été décue; comme ses deux devanciers, ce livre est d’une inappréciable valeur et d’un intérét scientifique immense au point de vue de l’étude des Lépidoptéres; i] est appelé 4 rendre de précieux services 4 tous ceux qui désirent pousser trés loin ]’étude biologique des papillons. C’est certainement l’ouvrage le plus complet qui a été écrit sur la matiére jusqu’a ce jour; il crée comme une nouvelle orientation. Ce livre prendra rang parmi les ceuvres des plus grands maitres de |l’entomologie. Cet ouvrage de 558 pages, d’un texte trés serré, est entiérement consacré 4 ]’étude de treize espéces de papillons nocturnes anglais (qui sont également de Belgique), c’est donc une moyenne de presque 43 pages de texte pour chaque espéce. : Tutt ne se contente pas de donner l’histoire naturelle compléte des espéces qu’il traite, mais i] y ajoute la description originale, la synonymie entiére du genre et de l’espéce, les localités d’Europe ot ces espéces ont été signalées. Outre ces renseignements, il donne encore, aprés chaque famille, un catalogue des espéces paléarctiques, ce qui fait de son livre une véritable bibliothéque entomologique. L’étude des variétés et aberrations est aussi parfaite qu’on peut l’espérer; l’auteur rencontre et décrit toutes celles qui ont été signalées tant en Angleterre que sur le continent. Il est intéressant de donner un petit apercu de la maniére dont l’ouvrage est composé. Aprés avoir traité de main de maitre tout ce qui se rapporte aux Familles, Tribus, Genres, etc., le savant auteur attaque l’espéce sous tous ses états, sous toutes ses formes—imago, dimorphisme sSexuel, gynandromorphisme, variation, ponte, ceuf, mceurs de la chenille, comparaison de la chenille, avec celles des espéces voisines, métamorphose. cocon, chrysalide, déhiscence de la chrysalide, parasites. plantes nourriciéres, mceurs et habitat du papillon, époques d’apparition. localités, distribution géographique, etc. Aprés ceci on peut se demander ce que les auteurs futurs pourront ajouter 4 |’histoire naturelle des Lépidoptéres. Rien, si ce n’est débrouiller le terrible probléme de l’origine des espéces et des variétés. Quelle somme de travail il a fallu pour écrire un tel livre, que d’auteurs il a fallu consulter, que de renseignements il a fallu demander aux naturalistes de tous les pays! Nous voudrions voir cet ouvrage dans les mains de tous les lépidoptéristes de notre pays; ce serait une récompense et un encouragement pour |’auteur de cet immense et utile travail. Puisse notre savant collégue étre 4 méme de faire paraitre sans retard son quatriéme volume qui est attendu avec autant d’impatience que les trois premiers, et puisse-t-il voir Vachévement et le couronnement de son ceuvre.’”’—L. J. L. LAMBILLION, Revue Jfensuelle de la Société entomologiqgue Namuroise. November, 1902. ‘Die dem vorliegenden 3 Bande vorhergehenden Volumina dieses bedeutsamen Werkes, welches—man kann wohl sagen—alles Aehnliche in den Schatten stellt, enthielten ausser dem sehr ausfiihrlichen allgemeinen Teil tiber den Ursprung der Schmetterlinge, Embryologie, Parthenogenesis, Variation, Schutzfarbung der Imago, Metamorphose, Morphologie, Phylogenie der Puppe etc., den Anfang des ersten Stammes (Stirps) des vom Autor aufgestellten und ausfuhrlich begrtindeten Systems, die Sphzngo-Micropterygiden. Der 1 Band (1899) behandelte die Superfamilien: Mzcropterygiden, Nepticuliden, Cochlididen und Anthrocertden. Den Anfang macht also eine Familie, welche bisher an den Schluss der ‘‘ Micro ’’-Schmetterlinge (es sei mir gestattet, den Ausdruck zu gebrauchen) gestellt wurde, eine weitere Kleinschmetter- lingsfamilie schliesst sich an und es folgen die unter der Bezeichnung Lzmacodiden und Zygaeniden gelaufigeren beiden. nach bisherigen Begriffen recht entfernt von einander stehenden Familien. In Band 2 (1900) erscheinen Psychziden und der Anfang der Lachnetden (=Lastocampiden). Zu ersteren werden einige Gattungen der 7zzezden und Ta/laeforiden. (Kleinschmetterlinge) gestellt, eine Neuerung, die im besonderen ebenso umwAlzend wirkt, wie das System im allgemeinen. Bei den Laszocampiden erscheintinmitten eine bisher zu den Vofodontiden gezahlte Gattung ‘NVadata), Band 3 bringt den Rest der Lachnerden, die Dinorphiten(=Endro- mididen), Bombyciden, Attactden, und den Anfang der Sphingid-n nebst einer Uebersicht der palaearctischen Lachnezden. — Als ein Factor zur Beurteilung der Griindlichkeit des Werkes mag gelten, dass in dem Bande von 558 Seiten nur 13 Arten Lepidopteren behandelt werden, wenn auch auf die allgemeine Systematik der Superfamilien Gruppen, Familien, Subfamilien, Tribus und Genera ein nicht unbedeutender Raum entfallt. Die Decentralisierung des Systems, so ausfitihrlich sie auch begriindet und klar durchdacht ist, wirkt fast etwas zu erschwerend auf das Ganze und méchte die Frage nicht unberechtigt erscheinen, ob hierzu eine dringende Notwendigkeit oder eine, dem Zwecke entsprechende Niitzlichkeit vorliegt. Die Revision der einzelnen Gruppen geschieht in des Sinnes weitester Bedeutung. Im besonderen beschaftigt sich die Systematik mit den in Grossbritannien heimischen Arten unter genauester Aufzahlung alles dessen, was uber die Biologie, Gynandromorphismus, Hybridismus, Verbreitung und Variation der Art tiberhaupt bekannt ist und spielt somit die Arbeit im Gebiete tuber, welche auch dem Sammler des Festlandes von ungemein grosser Bedeutung sind und welche dem Buch eine besondere Wichtigkeit verleihen, namentlich auch deswegen, weil eine ausserordentlich umfassende Litteraturcitation und Verzeichnisse aller bekannten paldarctischen Gattungen und Arten das Studium letzerer wesentlich erleichtern. Ebenso wie der Autor die generelle Systematik der héheren Einheiten mit einer ausgiebigen Zahl neuer Bezeichnungen, die sich im wesentlichen nur in der Endung unterscheiden, bereichert, wird auch eine gréssere Anzahl verschollener Genera wieder eingefiihrt und bei den einzelnen Arten eine, man méchte sagen, mehr als ausreichende Menge neuer Aberrationsnamen aufgestellt. Ueber den Wert solcher Namen ist schon viel gestritten worden. Eine gewisse Utilitat ist bei dem Prinzip, Spielarten zu benennen, nicht zu laugnen, wenn dies in massigen Grenzen geschieht. Bedenkt man aber, dass von den Individuen einer Art kaum eines dem andern véllig gleicht, und wollte man jede Farbenabinderung oder von dem Typus in sonst einer Weise gering abweichende Form benennen, so dirfte dies zu weit fiuhren und bei dem Sammler einen Grad der Mnemotechnik erheischen, der weit tber der Grenze des Geistes eines Durchschnittsmenschen liegt.

Dieselben bilden einen Teil der Lachneiden (Lasiocampiden) die Saturniiden, Endromididen und einen Teil der Sphingiden in der britischen Fauna. Diese Breite der Darstellung wird nur verstandlich wenn man sich vergegenwartigt, dass der Stoff eine Behandlung erfahrt, die weit iiber die Grenzen des Buchtitels hinausgeht. Die britische Fauna ist gleichsam nur das Skelet, welches diese encyklopddisch angelegte Riesenarbeit zu stiitzen hat. Und darin liegt auch ihre allgemeine Bedeutung. Der Resitz des Werkes, welches auch bibliographisch eine Musterleistung genannt werden muss, kann die Beniitzung einer Fachbibliothek, wenigstens fiir den Privatmann, fast entbehrlich machen.

In analoger Weise sind die Saturniiden und Sphingiden behandelt, deren allgemeine Systematik, vom historischen Standpunkte ausgehend, bei letzteren 40 Seiten beansprucht. Es liegt auf der Hand, dass eine solche Leistung nicht von einem Einzelnen bewaltigt werden kann und in der Tat hat das Werk auch eine grosse Zahl von Mitarbeitern gefunden unter welchen wir Namen wie Chapman, Bacot und Prout finden. Nach dem Gesagten besitzt das Werk eine weit tiber die Grenzen Englands hinausreichende Bedeutung, ja es muss namentlich fiir den literarisch arbeitenden Fachmann durch seinen encyklopadischen Charakter geradezu als unentbehrlich bezeichnet werden. . . . Wenn noch einige unwesentliche Ausstellungen—gewiss ohne Schmialerung des Gesamtwertes des Werkes—hier ausgesprochen sein diirfen, so ware es vor Allem der Wunsch nach Hervorhebung des hier Originellem und Neugebotenem, vor allem des hier zuerst Bekanntgemachten. Viele wertvolle Beobachtungen und Angaben sind als neu nicht sofort erkennbar, was bei Beniitzung des so breit angelegten Textes sehr winschenswert ware. — H. REBEL, Verhandlungen der k. k. zoologisch-botanischen Gesellschaft tn Ween. uly, 1903. J gree from a host of popular handbooks, there are two works on the Palzarctic Hawk Moths worthy of special notice. These are by Bartel, in Rthl, Grossschm., vol. ii., and by Tutt, British Lepidoptera, vol. ili. . . . Tutt’s work is the most intrinsic ever written on Palzarctic Lepidoptera. The third volume comprises only a portion of the SAhkizgidae; the remainder of the family will appear in the fourth. The work will be of the greatest help to the scientist who knows the matter well enough to be able to distinguish between what is scientific and what appears merely in a scientific garb. . . . There is nothing written any- where on European Lepidoptera coming up to it in thoroughness.—Rothschild and Jordan, A Revision of the Lepidopterous Family Sphingtdae. April, 1903. With remarkable and praiseworthy promptitude the successive volumes of this thoroughly scientific work are appearing to gladden the heart of the earnest worker in the most popular group of British insects, and we hardly know which to admire most, the zeal of the author in so rapidly producing the mass of information which is contained in each volume, or the thoroughness with which his work is done. Before dealing with the work more in detail, we must emphatically assert that, in our opinion, it is far and away the best account of our native lepidoptera that has ever been published; and, as much of the information relates to Scotland, both as regards distribution and variation, we cordially recommend the work to the notice of our northern entomologists. To the really scientific lepidopterist, indeed, Mr. Tutt’s volumes are quite indispensable. The present volume deals with the remainder of the 6th superfamily (Lachneides) of the Sphingo-Micropterygid strips, the 7th and 8th superfamilies (Dimorphides and Attacides), and a portion of the oth (Sphingides). The exhaustive nature of the work is shown by the fact that, in 540 closely printed pages, only 14 species are disposed of, that is, in addition to the accounts of the various genera and larger groups to which those species belong. The account of Lastocampa querctis occupies no fewer than 69 pages! The information there given is printed under the following heads:—Synonymy, original description, description of imago, sexual dimorphism, gynandromorphism, variation (39 pages), egg-laying, egg-parasites, description of ovum, comparisons of ova of different varieties, habits of larva (4} pages), description of larva, comparison of larve of different varieties, pupation, description of cocoon, description of pupa, comparison of pupa with that of Cosmotriche potatorta, dehiscence of pupa, foodplants, parasites, habits and habitat, time of appearance, localities, and distribution (3 pages of small type). What more could the most exacting seeker after information desire? The matter, too, is so well arranged that any particular fact, under any of the heads just quoted, can be found without much difficulty. The present volume is an improvement upon the two previous ones, inasmuch as the table of contents is more extended, but we would suggest a slight additional alteration which would, we think, be acceptable to all who use the work. If in the index, the figures indicating the page upon which the maz account of any particular genus or species commences were printed in Baliee type, it would save unnecessary page turning. Lastly the addition of a comprehensive index to this and the preceding volumes would be a boon, and we are glad to read PRESS NOTICES OF VOL. III. Xlil, in the preface that the author is willing to print one if carefully prepared by anyone who has the requisite time at his disposal.—P. H. Grimshaw, F.E.S., Zhe Annals of Scottish Natural History, January, 1903. “The third volume of Mr. J. W. Tutt’s British Lepidoptera is a really important book. It has been compiled on the same plan as the preceding volumes, though partly on account of the particular genera treated, but more from the catholic taste with which the author has brought together his materials, the present work is even more useful to the scientific entomologist than vols.iand ii. Jo the collector and systematist Mr. Tutt’s books are without doubt of high value. The analysis of specific and varietal characters is evidently made with extreme care, but, to the general naturalist, and especially to the student of evolution, the book has a direct and uncommon importance. Nothing of this kind has been attempted in any language hitherto. Mr. Tutt though modestly entitling his work A Natural History of British Lepidoptera, has gone much further afield than such a title would lead a reader to expect. For example, in treating Laszocampa guercus, we are provided not merely with a discussion of the British races, but an abstract is given of all that has been observed in the field or discovered by experi- mental breeding regarding the foreign forms and the laws which govern their heredity and variation. Again, in connection with the natural history of Satuznuza pavonia, Mr. Tutt introduces a full account of Standfuss’ important experiments in crossing the continental species. Many similar examples might be given illustrating the broad scope of the work. It may well be imagined that, in dealing thus liberally with species such as guercus, potatoria, pavonta, tiliae, populi and ocellata, all forms famous in the literature of variation and hybridisation, a very fine body of evidence has been amassed. Yo take the subject of gynandromorphism alone, it is scarcely too much to say that the raw material for a treatise is scattered through Mr. Tutt’s pages. The abstracting and condensation of the evidence, So far as it can be judged by one who is not a professed entomologist has been most carefully done, and the reader may feel confidence that, though the points are concisely put, exaggeration has been consistently avoided. Altogether, such a work is one to be thankful for, and there can be no doubt that such a publication will stimulate the younger generation of students to step from the narrow track of mere collecting, and to wander off into the more fertile fields of experiment and observation of living forms. Mr. Tutt tells us in his preface that if anyone will make a subject index, he will print it in the next volume. Cannot some keen young worker take him at his word? Meanwhile the student of evolution must not be daunted by the difficulty of putting his hand at once on the fact he is looking for, and the physiological chzffonzer, as Claude Bernard calls himself, may be assured that, if he will only rummage about a little, he will pick up some rare treasures in Mr. Tutt’s heap. To include everything that can by any possibility relate to, or interest the student of, the British fauna, is to err on the right side, though the connection with that fauna be rather remote. Now and again, however, we come on a few pages which are very doubtful in point. Space being so valuable, we feel that, for instance, the details regarding the structure and classification of the Attacides of the world need not have found a place here, not that the facts are unimportant, but no one is likely to look for them in a work on a fauna which contains one solitary species of the group. ‘The unprofessional reader wonders, too, who zses the solid pages of locality records in the case of species widely distributed. When these records detail the varieties of the districts their value is manifest, and they will form a solid basis for the observation of future changes in distribution. Did we not feel sure that, in this case, the author knows the requirements of his public, we might be disposed to question whether this was really the best use to which the labour and space could have been put. None of these remarks, however, detract from the statement that the new British Lepidoptera is a fine scholarly piece of work, for which not only the entomological specialist, but naturalists of all orders, will be thankful to Mr. Tutt for many a year.’”’—W. Bateson, M.A., F.R.S., Axztomologist’s Record, &c., December, 1902. “The third volume of this work has now appeared. It is of the same exhaustive character as those which have preceded it, as may be inferred from the fact that, in its 558 pages, only thirteen species are described, z.e., the remainder of the ‘ Lachuezdes’ (Lastocampa quercts, etc.) D. versicolora, S. pavonia, the three species of the old Smerinthid genus, and the two British ‘ Bee-Hawks,’ H. fuciformis and H. tityus (bombyliformis). As an example of the author’s exhaustive treatment, Z. guerctis may be cited. All lepidopterists know the vast amount of discussion that has taken place since the var. cad/wnae was introduced about 1847 as a distinct species. The immense amount of information since obtained as to the habits of this species in different regions of Europe and Asia is brought together and discussed in about 80 pages, in a manner which seems to leave scarcely anything more to be said. It would be an error, however, to suppose that the volume is limited to descriptions of thirteen species, their many varieties and recorded aberrations, their life-histories, habits and localities. These, indeed, are given in very great detail; but the relations of the species found in our islands to those found in the rest of world are always kept in view, and the result is that - a very large proportion of the 558 pages-is devoted to information and discussions of as much interest to Continental and American lepidopterists as to our own. In this connection I would draw attention to the frequent observations on the conjectured phylogeny of the species, and of the genera, families, etc., to which they belong, and on their proper places in a classification based on the observation of the insects in all their stages. A knowledge of these is, of course, essential for this purpose, seeing the different traces of their probable origin which they bear in these stages, and the diversity of the directions in which, in these several stages, owing to the entirely different lives they lead in them, they appear to have evolved. As regards phylogeny in general, the observation at p. 359 is deserving of being well weighed. The passage is too long to quote, but it comes to this, that what we call the ‘ lowest’ members of a stirps are as many generations from the common stock as the ‘highest’ are; we may construct a hypothetical ancestor, having all the generalised but none of the specialised characteristics of a group, the members of it having specialised in different directions so that no existing form can be supposed to be derived from any form now existing. Iam so thankful for the great labour which has been expended by the author and his coadjutors in obtaining and recording, with the necessary accuracy required, the detailed information contained in the work, that I do not like to suggest that, ifeven more labour could have been given, the value of the work might have been greater still. But when I find that such a common and widely distributed species as C. fotaforza has more than five closely printed pages devoted to dates and localities of capture in the British Isles, I cannot help thinking that a compressed and classified summary, which need not have occupied more than half a page, would have been preferable. There are other cases also in which it appears to me that compression and condensation would have been usefully employed. Even if XIV. PRESS NOTICES OF VOL. III. Mr. Tutt agrees in this opinion, his answer might be that of the accomplished letter-writer who accounted for the length of his communication by saying that he had not time to write short; if this be so, it is greatly to be regretted, and one is all the more glad that he has had, and will we hope for the succeeding volumes have, the valuable co-operation of such excellent and thoughtful observers as Dr. Chapman, Mr. Bacot, and Mr. Prout, whose aid he acknowledges so heartily.” —F. Merrifield, F.E.S., The Entomologist’s Monthly Magazine, November, 1902. “Tt is pleasant to be able to review such an eminently satisfactory book as isthe third volume of ‘ British Lepidoptera.’ Its predecessors were very welcome, but to a large number of entomologists the mass of material relating to the ‘Micros’ was probably unread, and thus a large portion of volumes i and ii, appeals only toa limited number. This third volume, therefore, should find more support, as the species treated of are all very well known to the great majority of callectors. The minutiz inevitably involved in such an undertaking are again manifest, and with what effect they have been utilised it is for each individual to judge for himself. It is strongly to be hoped that the necessary increased support will be forthcoming, and that many more numbers are in store for us. The superfamily Lachneides is continued, and the first species treated is Pachygastrza trzfolzz, which occupies exactly thirty pages. Following this comes the species that has doubtless caused more research and taken up more time than any hitherto already done, vzz., Lastocampa guercus. Preceding the description and all that follows concerning the life-history of the type and its numerous forms and varieties, is a summary of the experimental work in the hybridising of the different local races. Although nominally we have no chapter to commence vol. iii, this summary of hybridisation is a very good substitute, and has as much general interest as any such that has appeared in the previous volumes. By the time the * Times of Appearance,’ ‘ Habits,’ * Localities,’ etc., have all been worked through, eighty pages have been covered over this species alone, and it is doubtful if anything of any moment concerning this insect can have escaped Mr. Tutt’s attention. Passing onto Wacrothylacia rubcvand Cosmotriche potatoria, perhaps one of the most interesting collection of facts is to be found in the diver- sified character of the habits of the larvze of these two species. To the former as much as five and a half pages are alone given to this part of thescheme. Gastropacha tlic¢folia comes in its turn, with full descriptions of larva, cocoon, pupa, food-plants, parasites, and so on, and the collector will doubtless read with avidity the ‘ Habits and Habitat’ section. Under Dimorpha versicolora the question of its allies is freely discussed and the reader is referred back to vol. i., pp. 124-125, and vol. ii., p. 440, for further discussion. One cannot help wishing, however, that the author would point out where (when possible) the imaginal characters are in agreement with the biological ones in assigning, or helping to assign, a position toa subfamily. The larval and pupal habits under this species are again full of interest, and cannot fail to engage the atten- tion of both student and collector. At p. 265 the superfamily Attacides is brought under review. In the preface the author says heis entirely dissatisfied with his knowledge of the relationships of the various families of the Saturniides (Attacides) zZe7 se, of those of the Sphingides zvzZer se, and of these two superfamilies to each other. It, however, cannot be that he has not probed deep enough, for the thirty pages or so, before our only British Attacid (Saturnza pavonia) is treated, require the closest attention of the reader. The very thorough examination and diagnoses of the characters afforded by the larve of the Attacides will call for time and thought for full digestion. From p. 342 to the end of the volume the classification and position of the Sphingides are discussed, and the complete natural history of the British species of Amorphinz and Hemarinz recorded. Starting with Linnzeus, and working through Fabricius, Scopoli, Lamarck, Latreille, Hiibner, Laspeyres, Oken, Leach, Dalman, Ochsenheimer, Swainson, Boisduval, Stephens, Curtis, Duponchel, Duncan, and Westwood, a very complete review is given of the generic synonymy of the British Sphingids, and at the close a list of the types of the genera deduced is set forth, Another long diagnosis is given to the history of the superfamily, and starting with Réaumur, the works of Hiibner, Stephens, Grote and Robinson, Butler, Herrich-Schaffer, Meyrick, Poulton, and Dyar, are all brought under the focus in the order given. On pp. 365-366 is a scheme, drawn up by Bacot, for separation into genera, based on larval characters, and closely following is a family and subfamily division proposed by Chapman. Concerning the latter, one notes that the ' Sesiinze are only separated from the EKumorphine by the tufts to the abdomen, a character that certainly does not hold good throughout. Perhaps, in vol iv, some better character will be furnished when the true Macroglossids come to be reviewed. The high specialisations of larva, pupa and imago are fully discussed. The details concerning the pupa offer food for reflection, both as regards the proboscis-casing and the varying position of the glazed eye, which latter, if we are not mistaken, is brought forward for the first time. We have descrip- tions given of all the different hybrids produced in the Amorphinz, not the least interesting being the comparison between the hybrids produced by Amorpha populé and Smerinthus ocellata, and hybrids from Amorpha austauti and Smerinthus atlanticus. A very complete classification of the forms and aberrations of A/zmas f¢7/rae is to hand at p. 404, and the same long lists of localities are given, showing in many cases unsuspectcd curtailment or otherwise in the range of distribution. On reference, for instance, to Hemarzs fuctformis, it is noted as ‘exceedingly rare, if not entirely absent, in Scotland and Ireland.’ No one, after this, will deny that these extended lists serve a purpose other than that for the collector. In conclusion, there is only one matter we really regret, and that is that we have had to wait two years for the present instalment. It is pretty certain, however, that the book is all the more complete.— W. J. Kaye, F.E.S., Zhe Entomologist, December, 1902. “ After an interval of but little more than two years, we have again the pleasure of re- viewing another volume of Mr. Tutt’s enormously laborious and comprehensive woik on the British lepidoptera. ‘The size and the manner of execution are similar to the two preceding volumes; but it is entirely systematic, as no space could be spared for chapters on general subjects, and perhaps, as a consequence, vol. iii contains no illustrations. We are glad to see that Mr. Tutt has adopted a suggestion made by some of his critics, and has given a somewhat fuller table of contents, which will much facilitate the use of the book. eee Volume iii contains the continuation of what Mr, Tutt calls the ‘ Sphingo-Micropterygid Stirps,’ and includes the Lachnetdes, Dimorphides, Attacides, and part ot Sphingzdes, the entire volume being devoted to 13 species only, vzz., Pachygastria irifoliiz, Lastocampa quercus, Macrothvlacita rubi, Cosmotriche potatoria, Gastropacha tlictfolia, Eutricha querct- folia, Dimorpha verstcolora, Saturnia pavonta, Mimas tiliae, Smerinthus ocellata, Amorpha popult, Hemaris fuctformis and H. trtvus, Of course, every species will not require to be treated at the same length as Lastocampa guercus, which occupies (as a species) no less than 69 of Mr. Tutt’s closely-printed pages, but we tremble to think of the number of volumes PRESS NOTICES OF VOL. III. XV. and the number of years which will be required to deal with over 2000 species of British lepidoptera on the same scale. : Turning to more general matters, the abstracts given of different systems of classification of groups, often taken from old or scarce books, will be most useful to all students who have not access to the best entomological libraries. Mr. Tutt seems to aim at making his book a huge compendium and cyclopzedia of all that has been published on the species of which he treats; and it will be of great value to generalising entomologists, who will be able to sift from it a great amount of valuable infor- mation in furtherance of their special studies. A large amount of information is given respecting foreign species, especially those of continental Europe and North America; and also on parasites, and various other subjects incidentally connected with the main subject of the work. We are sorry to find that there is only a meagre list of new subscribers since the last volume; but, as the work is necessarily too costly for many entomologists, and must become increasingly so with the publication of each volume, we would wish to emphasize its great value as a book of reference for public Natural History or Entomological Libraries, especially at a distance from London or the University towns which alone possess full series of the books of which Mr. Tutt’s work is largely an abstract -not that we do not also fully recognize the large amount of material due to the original observations of Mr. Tutt and his coadjutors. which is published. here for the first time.—W. F. Kirby, F.L.S., The Annals and Magazine of Natural Historv. ** The 3rd volume of Tutt’s British Lepidoptera has appeared, and is fully up to the standard of the first two volumes. ‘The superfamily Lachnerdes is completed, the superfamilies Dzmorphides (Endromides), Attacides, and a part of the superfamily SpAzugides are finished. The references to literature, ancient and modern, seem to leave nothing more to be desired in this respect ; in fact, the amount of labour performed and research that has been made seems almost appalling, and we wonder whether the author has the strength and endurance to carry such an undertaking through to completion. This work may well be taken as a model by one who is less experienced, provided he does not follow it too closely and thus destroy his own originality of thought and plan. Under each superfamily is given a very complete history of the classifications of the different authors. These are carefully discussed, and when the author differsfrom others he does not hesitate to express his convictions. Many of our old familiar names have disappeared, and are to be found only among the tail-feathers of synonymy. ‘This is, however, strictly in accordance with the law of priority, and if any of us feel unreconciled to this, we may well ask ourselves whether we are to keep up with the trend of modern scientific thought or fall by the way. Under each species is given the synonymy and references to literature, so full and complete that we can hardly imagine anything of importance to have been overlooked. Then follows the original description in the language in which it was published, and this is followed by the author’s description of the imago. ‘There is then given a full account of sexual dimorphism and gynandromophism (more than 5 pages being devoted to gynandromorphous examples of Amorpha populr, L.). Variation is also taken up very fully with all the forms described and named, and this requires 7 pages for A. Jopulz alone. A complete account is given of the time, place, and manner in which the eggs are laid. followed by a full description of the egg, the larva in each stadium, and variations of the larva, pupation and cocoon, pupa, foodplants, parasites. habitats, time and place of appearance and distribution. While this work must prove indispensable to the entomologist who desires full information on the lepidoptera of the British Isles, it will be exceedingly valuable to students of the lepi- doptera in the United States and elsewhere, because of the exhaustive study of the literature of the genera, and higher groups, and the careful and conscientious manner in which the author applies the laws of nomenclature.’’—C. H. Frernarp, M.A., Ph.D., F.E.S., The Canadian Entomologist, January, 1903. “Two years after the publication of the second volume, the third volume of British Lepidoptera has been completed. It differs from its predecessors inasmuch as it is not divided into two parts, but deals throughout with the species continued from vol. ii. The first species dealt with is Pachygastria trifoltt, the last Hemarzs tetyus (bombyliformis). One has little doubt that, of all the species dealt with, Laszocampa qguercts will come in for the most notice, The history of this species occupies no less than 70 pages, much of it is in small type, and the whole composed of summarised detail dealing with facts, and without a word that could possibly be spared. Little that has ever been published on this interesting species can have escaped the search-net, and the full details of the variation will not only prove of the highest interest to all students and collectors of lepidoptera, but the critical onslaughts made on the misuse of the varietal names on the continent will necessitate a thorough study by continental lepidopterists. Short notes on Laszocampa var. callunae, often repeated ad nauseam with no fresh facts or details, and stating simply what has been published so often before, by recruits who are for ever finding out something quite new because of their ignorance of previously published matter or their inability to find it, must of necessity be fewer in number or more scientific in character now that the details (pp. 73-85) so industriously collected by the author can be so readily studied, for these pages do not represent the author’s opinion of the subject, but the opinions and facts of all lepidopterists who have handled the subspecies since 1849, when Palmer first described it. To many the account of Dimorpha versicolora will be especially welcome, consisting as it does of 35 pages (pp. 229-264) of solid matter relating to this interesting species, and embodied in which one finds descriptions of no less than ten striking gynandromorphs, a complete life-history based on the observations of Chapman, Bacot, Holland, Clarke, Gascoyne, Merrifield, Buckler, Bernard-Smith, Poulton, Jenvey, Bankes, Tugwell, etc., whilst more than a hundred other lepidopterists are quoted for details relating to localities, dates of appearance, habits, etc. As a matter of comparison, however, it may be noted that Gastropacha tlicifolia has been worked out in such detail as to require from pp. 186-199 to describe it and its habits in their various aspects, and practically every detail of our knowledge of the species in Britain is here embodied, as well as a complete life-history never before published. The less than a dozen lines of Newman on Hemaris tityus, with at least two glaring errors, become here some twelvesolid pages of detailed facts, checked with the authorities and vouched for by their names. These two species are those that occupy the least space; the other species are worked out in the same careful manner, but with more facts and details. To the biologist the extensive details relating to the hybridity, gynandromorphism and life- histories of the species treated, will prove a mine of information. The account of Swerinthus hybr. Aydrzdus (pp. 448-459) is of the greatest value as a summary of all the work published on this best known hybrid form ; but the details on pp. 391-395 will prove no doubt of still more interest. XVi. PRESS NOTICES OF VOL. III. The description and account of /zmas hybr. Zeonzae, a cross between Mzmas tiliae and Smerin- thus ocellata; of Calasymbolus hybr. znterfaunus, a cross between a fof the American Calasym- bolus astvlus and a @ of the European Smerinthus ocellata; of Smerinthus hybr. oberthirz, of S. hybr. frzxgsz, Amorpha hybr. metis, and A. hybr. zzversa, are full of interest, whilst on pp 291-204 are the details of numerous Attacid crossings, and on pp. 296-304 a full summary of the crossings of the allied European Saturnians ; there is no need to state that full accounts of the crossing ex- periments of Laszocampa guercus and its various races are also given. The details relating to gynandromorphs are most interesting. Scarcely a species that is here treated but has given some examples, and when one notes no fewer than 32 gynandromorphs of Laszocampa guercus described, 60 of Saturnia pavonta and 80 of Amorpha populz, besides smaller numbers of other species the biologist will recognise that he has here an ‘abundance of material on which to work. The British collector. will turn with the greatest satisfaction to Chapman’s comparison of the life-histories of Amorpha populi, Mimas trliae and Smerinthus ocellata, and the author’s grouping of the Amorphids should at least flatter the vanity of the City of London Entomological Society, which one knows he loves so well. The names of Messrs. Sich, Burrows, Kaye, Dadd, Bell, Nicholson, and Clark are all laid under contribution for new genera, arid no doubt other members’ names are only missing because they have been previously utilised. To the systematist there are four chapters that will require time, thought and digestion. Firstly the account of the family Lutrichidae (pp. 111-123). Secondly, the study of the position of Dzmorpha (Endromzs} (pp. 229-236). Thirdly, the classification of the Attacides, a detailed account of all the work done in this direction (pp. 265-290); and lastly the exhaustive chapter on the literature, synonymy and classification of the Sphingides (pp. 342-382). _ Much internal evidence shows that the author hopes to attract criticism on this part of his work, and his preface tends also to point in the same direction. As to this, the final conclusion of the author on the actual types of the genera he uses may be worth quoting . . . . It is of no use after this for the British collector to cavil at the change of names; here he has the whole literature of the subject at disposal so that he can form his own opinions, and the author himself provides the material on which such may challenge him if they disagree with his conclusions. ‘The Catalogue of the Palzarctic Lachneides’ (pp. 225-229), and the ‘Catalogue of the Palzarctic Dimorphides, Bombycides, Brahmzides and Attacides,’ will prove of the utmost use to workers both in the Palzarctic and Nearctic regions, although probably for matters of space the species of the latter district have been excluded. ‘The author asks for a full measure of support from all lepidopterists. He especially appeals to American lepidopterists to support the work, claiming that the volumes have a wider basis than their title would suggest, and pointing out that the basis of work is general, and, therefore, of as much importance to American as to European lepidopterists.’’?— Lhe Entomologist’s Record, October, 1902. “*Ein englisches Werk, das der Aufmerksamkeit auch der deutschen Naturforscher und besonders der Schmetterlingskundigen empfohlen zu werden verdient, ist ‘ J. W. Tutt’s Natural History of the British Lepidoptera.’ Dasselbe ist nach den Mitteilungen des Verfassers auf vier Bande berechnet, von denen die drei ersten bereits erschienen sind. Das Buch ist mehr, als sein Titel besagt ; es beschrankt sich nicht auf die britischen Schmetterlinge, sondern zieht alle mit ihnen verwandten Arten und Varietaiten, wo immer sie vorkommen mégen, tberhaupt alles, was mittelbar oder unmittelbar mit dem Thema im Zusammenhange steht, in den Bereich seiner Betrachtungen. Das Werk nimmt aber auch uberall Ricksicht auf allgemeine Fragen. So widmet der erste Band 112 (von seinen 560) Seiten eingehenden Erorterungen uber: 1. Ursprung, 2. Ki, 3. Embryologie, und 4. Parthenogenesis der Lepidoptera, 5. dusseren, und 6. inneren Bau der Schmetterlingslarve, 7 Variation der Imagines, & Schutzfarbung und Verteidigungsmittel der Larve, 9 Klassifikation der Schuppenfligler. Hierzu kommen im zweiten (584 Seiten starken) Bande 100 Seiten Betrachtungen uber: 1, Metamorphose der Lepidopteren und 2. zufdllige Erscheinungen dabei, 3. 4ussere Morphologie und 4. inneren Bau der Schmetterlingspuppe, 5. Abstammung der Lepidopteren (mit Stammbaum). Auch der dritte Band bringt iber biologische und andere Fragen (Hybridismus, Gynandromorphismus, Variation, Entwicklungszustande, Metamorphosen usw.) eine Menge Details, eine Anhaufung von Material, das anderswo grossenteils tiberhaupt nicht zu erhalten ist, und in einer so erschopfenden Vollstandigkeit, wie sie bisher noch in keinem der einschligigen Werke erreicht worden ist. Dieser Inhaltsreichtum gibt dem Schmetterlingsforscher stete Anregung, seinen Untersuchungsgegenstand von allen moglichen Gesichtspunkten aus zu studieren, sich unablissig eine vollstandige Erforschung der Insektenwelt angelegen sein zu lassen, die simtliche Entwicklungszustande des Schmetterlings umfasst, nicht nur uber dessen Bau, sondern auch uber seine Physiologie und Biologie, seine Wandelungen und Aenderungen, Habitus, Fundorte, Nahrungspflanzen, geographische Verteilung usw., die verwandtschaftlichen Beziehungen der Arten, die Varietaten usw. -Aufschluss gibt. Somit findet auch der Phaenologe tiber die Schmetterlingswelt in ihrer Abhangigkeit von klimatischen Einflissen tiber die Wohnbereiche der’ Arten usw. in Tutts grossem Werke eine Fille der Belehrung, Anregung und Auskinfte. Dem Phaenologen, wie dem eigentlichen Sammler erleichtert das Buch die Arbeit ausserordentlich; Jahre lang mussten sie studieren, forschen, sammeln—und dann hitten sie doch noch lange nicht die Menge der fir ihre Spezialarbeit in Betracht kommenden Angaben, Daten und zuverlissigen Informationen beisammen, die ihnen hier in Tutts Buche wie auf dem Prisentierteller dargeboten. zur sofortigen Verarbeitung fertig, entgegengebracht werden. *s handelt sich aber nicht blos um Zusammen- tragung einer Menge von Material aus allen nur erreichbaren (britischen und ausserbritischen) Quellen, um die mit ausserordentlicher Sachkenntnis und gereiftem, fachmannischem Urteil durchgefihrte Anordnung, Sichtung, Formung, Kondensation und Wirdigung des ungeheueren Stoffes ; sondern jeder Band des Werkes steuert auch zu dem wohlgeordneten und gesichteten Riesenvorrate des bisher bekannten Wissens, der friheren Beobachtungen noch reiche Spenden ganz neuen, noch nirgends gedruckten Materials teils aus des Verfassers eigenem Wissensschatze, teils aus der Feder seiner Freunde und Mitarbeiter bei. Bei einem litterarischen Unternehmen so umfassenden Charakters ist es ja unmdglich, dass die kolossale und vielseitige Arbeit von der Kraft eines einzelnen Menschen bewdltigt werde. So enorme Arbeit [utt auch geleistet hat, so bedurfte er selbstverstandlich doch der Mitarbeiter, und er fand sie unter den nambaftesten Fachmannern seines Vaterlandes. TIT. A. Chapman, A. W. Bacot, L. B. Prout, Kirby, Durrant, Lord Walsingham, W. H. B. Fletcher, Dr. Wood und andere mehr haben ihre Dienste dem ‘Luttschen Unternehmen geliehen; ausser diesen Gelehrten aber haben noch tiber 200 Entomiologen auf die eine oder andere Art bei einzelnen Fragen ihre Beobachtungen, Aufzeichnungen, Listen, Berichte, Auskinfte zur Verfigung gestellt. Dazu ist die gesamte vorhandene Literatur, soweit sie in Betracht kam und zugiinglich war, alles, was in Buchern, Abhandlungen, Fachblattern, PRESS NOTICES OF VOL, III. XVil. Magazinen, Vereinsberichten, Verhandlungen gelehrter Gesellschaften und Korporationen, Zeitungen usw. an einschlagigen Notizen und Erorterungen zu finden war, mit grosser Sorgfalt gesammelt worden. So sind nicht nur die britischen Quellen, sondern auch die auslandische Literatur (hauptsachlich die deutsche und amerikanische) herangezogen worden. Auch manche noch ungedruckte Arbeit konnte benutzt werden. Auf diese Weise ist denn ein Sammel-und Nachschlagewerk zu Stande gekommen, das besonders in seinem klassifikatorischen Teil eine wahre Fundgrube der Belehrung bildet. Was Vollstandigkeit betrifft (schreibt Merrifield), so steht Tutt’s Werk in der Fille der Detailangaben itber alle den Biologen, Systematiker, Sammler, kurz jeden Fachmann interessierenden Fragen geradezu einzig da. Dazu kommt, dass das Buch bis auf die Gegenwart fortgefihrt ist und die gesamte Literatur der zu dem Fach gehdérigen Gebiete benutz hat. Die Klarheit der Darstellung erh6ht noch den Wert und die wissenschaftliche Brauchbarkeit des Buches, das dem Forscher unschatzbare Dienste leistet als Ratgeber, der ihn kaum jemals-im Stiche lasst und als Auskunftsbuch, das ihm nicht leicht die Antwort auf eine Frage schuldig bleibt, das vielmehr tberall mit grossem Scharfsinn zusammengefasst die neuesten Ergebnisse der entomologischen Forschung darbietet und zwar ohne Weitschweifigkeit, in moglichst knapper, aber doch lesbarer Form. Dem Sammler geben die sorgfaltig ausgearbeiteten Listen wohl beglaubigte Auskunft, wo und wann er jede Art der in dem Buche behandelten Schmetterlinge finden kann. Auch iber die Jahreszeit, in welcher eine Schmetterlingsart erscheint ist ebenso, wie iiber ihre Wohnstatten, Fundorte und Nahrungspflanzen das gesamte Material in Tutts Werk zu finden. Ferner enthalt das Werk vollstandige Listen der Synonymen der einzelnen Arten und Gattungen, sowie der literarischen Hinweise, und diese Angaben sind zuverlassig, Tutt zeigt sich auch hier als ein Meister der Kompilation und knappen Zusammenfassung. Vonbesonderem Interesse und grossem Nutzen ist der Wiederabdruck der ersten Beschreibungen der einzelnen Arten. Doch sind auch neue Beschreibungen hinzuge- kommen, und alle Mitteilungen iiber Lebensverhdltnisse und Entwicklung sind nach modernen Gesichtspunkten ausgearbeitet. Ein weiteres Verdienst des Buches besteht in der Vollstandigkeit, mit welcher die fremden Ansichten angefthrt und gewiurdigt werden unter Hinweis auf die Gesichtspunkte, von denen der Verfasser dabei ausgeht. Hier tritt oft seine Selbstindigkeit und Originalitat recht deutlich hervor ; tberall bringt er in summarischer Form auch die neuesten und gewichtigsten Ansichten, vervollstandigt aber diese Zusammenstellung noch durch die Ergebnisse seiner eigenen Forschungen und kritischen Untersuchungen. Tutt griindet seine Klassifikation hauptsachlich auf die Lebensbeschreibungen der Schmetterlinge, und da er hierbei das Ganze der Entwicklung, samtliche Stufen und Eigentiimlichkeiten, die Gesamtheit der Erscheinungen, alle Seiten der Sache im Auge hat, so ist sein Werk nicht nur ein Denkmal kolossalen Fleisses, unermiidlicher Arbeit und Sorefalt, sondern es bedeutet auch einen wissenschaftlichen Fortschritt und hebt das Studuim seines Wissensgebietes auf eine weit hohere Grundlage, als die bisherige war. In der Beschreibung der einzelnen Spezies geht das Werk ju. a. auf folgende Gesichtspunkte ein: 1. verschiedene Benennungen, 2. Originalbesch- reibung der Art, 3. Imago, 4. sexeuller Dimorphismus, 5. Gynandromorphismus (Beschreibung aller bekannten Formen davon), Variationsformen, Abweichungen usw., 6. Vergleich mit verwandten Arten, 7. Eiblage und Ei, 8. Larve, 9. deren Habitus, 10. und Variation (Tabellen von sdmtlichen Variationsformen der betreffenden Art), Vergleichung der Larve mit den Larven verwandter Arten, 11. Kokon (Doppelkokons und zusammengesetzte Kokons), Verpuppungsart, 12. Farbenanderungen am Kokon, 13. Auskriechen aus der Puppenhulle und Habitus der Imago, 14. Ndahrpflanzen (vollstandige Verzeichnisse und Aufenthaltsorte), 15. verlingerte Dauer des Puppenzustandes, 16. Erscheinungszeit (phanologische Details), Puparium, 17. Fundorte (Listen fur die Bezirke Britanniens), 18. geographische Verteilung (Listen der Verteilungsbezirke der Arten nach den einzelnen Landern, in denen sie vorkommen). So gibt das Werk eine Uebersicht tiber die betreffenden Gruppen, Familien und Genera, tber ihre Kennzeichen, Lebensweise, Klassifikation und ihre Verteilung in der ganzen Welt, ttber die Namen der Arten. tiber die Stellen, wo sich Beschreibungen der Arten, Varietaten oder andere Mitteilungen uber sie finden, uber die ganze, auf die Art. Gattung usw. beziigliche Literatur. Der Preis des Bandes betragt 20 M@. In Anbetracht der aufgewendeten Arbeit und angesichts der Tatsache, dass dieses Werk dem Forscher eine Masse Zeit, Mithe und Umstande erspart, und dass diese Bande gleichsam eine ganze Bibliothek darstellen voll Belehrung und Informationen, die man sich sonst in der Praxis nur mit grossen Schwierigkeiten oder iiberhaupt nicht zu beschaffen vermag, erscheint der Preis nicht ibermassig hoch. Die britischen und amerikanischen Fachzeitschriften sind tiber das Tuttsche Werk des Lobes voll. Die Ermachtigung zur Verdeutschung des Werkes hat der Verfasser einem unserer Landsleute freundlicher Weise bereits iibertragen. Vielleicht finden sich Subskribenten auf eine deutsche Ausgabe des Werkes in hinreichender Anzahl. um einem unserer Verleger die Besorgnis zu nehmen, er konne sich mit der Herausgabe einer deutschen Uebersetzung ein zu grosses geschdftliches Risiko aufladen. Fachgenossen, welche sich fur die Angelegenheit interessieren, werden gebeten, sich mit Herrn O. Marpurg, Cothen (Anhalt), Schiitzenstrasse 10, in Verbindung, zu setzen.’’—M. GILLMER, /zsekten-Borse, March, 1903. ‘* British entomologists are to be congratulated on having obtained such a valuable handbook on their native lepidoptera, and we hope that the author will be able to complete the work on the same lines . . . But to lepidopterists in other countries the work is of great im- portance, particularly for the comparative study of the variation in structure and habits of the Same species in different regions. _It is only to be regretted that the price of the work may render impossible its being obtained by some private students.” —CHR. AUvRIVILLIUS, Hon. F.E.S., Entomologisk Tidskrift, April, 1903. PRIPISH LEPIDOPTERA. _ Superfamily IX: SPHINGIDES (concluded). Family : SPHINGIDA. Subfam.: SESIINA. This subfamily has already been dealt with somewhat at length in our consideration of the Sphingids (anéed, vol. 111). It has also been: characterised (loc. cit., pp. 366—367) and compared somewhat in detail (loc. cit., pp. 503 e¢ seg.) with the Hemarids, a subfamily closely united by lepidopterists to the Sesiids, and it must be confessed that there is considerable resemblance between the two groups in all their stages except the pupal. The Sesiid egg is small, laid upon the foodplant, and possibly specialised to resemble the buds amongst which it is often placed. The larva is very typically Sphingid, with well-developed caudal horn, a small head, and only very slightly retractile thorax; in its first stadium it has tubercles 1, ll, 11, 1v generalised in position, that which is usually considered v being, as in other Sphingids, distinctly prespiracular, a feature apparently fairly characteristic* of the superfamily ; each of these tubercles bears a single bifid hair; on the meso- and metathorax, however, i and ii are placed on a common base ; in the later stadia, there is a | growth of secondary bifid hairs. In these respects, Hemarid and Sesiid larve show striking resemblances. The pupz, however, are characteristically different, and ally the species closely with the Eumorphids. Chapman, who has examined the pupa of Sesza stellatarum, and seen those of some half-dozen other Sesiid species that agree with it in general characters, says: ‘It is not easy to say wherein the Sesiid pupa differs from that of the Eumorphid section, in which the pupe have the labrum dorsal and the front of the pupa occupied by a deep maxillary keel, whilst one is inclined to place the pupa of /Veshe/e with the Sesiids rather than with the Eumorphids. The chief difference is that the Sesiid pupa is usually very markedly compressed from back to front, whilst the Eumorphid pupa is more or less cylindrical, z.¢., of circular section. Another frequent character (wanting in the pupa of S. stellatarum) is a raised line or ridge across the anterior margin of the segment dorsally, passing close in front of the spiracle as it fades out * Bacot has recently found v united with iv on a common base on the Ist abdominal segment of the larva of Ayles euphorbiae in its first stadium, 2 BRITISH LEPIDOPTERA, anteriorly. The Sesiid pupa agrees with the Eumorphid, in that some species have the anal spike sharp and pointed, whilst others have it rounded or spoon-shaped at the end. ‘The pupal structure leaves little doubt that the Sesiids are a branch of the Eumorphids and are not directly related to the Hemarids. The pupz of many of the species have a tolerably firm structure, but that of S. stellatarum is more typical in shrivelling up if it dies, whilst, on dehiscence, it more usually twists and shrivels up than retains its natural outline. It has a very delicate skin, connected no doubt with the fact that it pupates above rather than under the ground, and, perhaps, more especially, that it does not hybernate as a pupa but passes a very short time in that stage.” Kaye remarks (zm Zit.) on the immensely varied characters shown by the Sesiid imaginal structures, ¢.g., the antenne (which range from fairly long and slender to somewhat short and thick, whilst sometimes they are moderately clubbed and in others scarcely so), and the tufted abdomen (which appears to be only of service as a character when considered in conjunction with other structures, and sometimes varies sexually). The hind tibiz he finds to be more bristly-scaled in the Sesiids than in the Eumorphids, and states that, frequently, quite a tuft of scales eccurs round the base of the spurs. These latter, too, appear never to be so free and conspicuous in the Sesiids as in the Eumorphids. He suggests that the greater number of the Sestinae fall into three natural tribes: 1. Wings not angulated; g and ¢ with anal and lateral tufts .. 56 v. oe ae -. SESTUMIS 2. Wings angulated. a. 6 and ? tufted a se a os CY Re 6. ¢ only tufted Sh 35 .. LOPHURIDE These tribes would not embrace all che genera hitherto included in the Sessz7vae. Undoubtedly further tribes will have to be erected for some of the more isolated genera. Tribe : SESIIDI. This tribe is well-characterised by the widely distributed and well-known Sesta stellatarum. Its structure has been already dealt with in our consideration of the subfamily. The imagines are remarkable for their swift flight, seeking flowers by day, into which they thrust their long maxillez whilst poised onthe wing. | Reference to Bates’ comparison with the true humming-birds (Vat. on River Amazons, pp. 182—183) may be made here. | The i imagines are well-scaled and usually have a markedly tufted abdomen. Kaye notes, however, that Enyo is decidedly nocturnal in its habits, but, in spite of being some- what aberrant, is still distinctly Sesiid. The tribe is widely distributed throughout the whole of the Old and New Worlds, but is particularly abundant in the Indian region, tropical Africa and tropical America. Genus: Srsta, Fabricius.

The heterotypical genus Sesza was erected by Fabricius in 1775 for section III of Linné’s comprehensive group Sphinx. It was diagnosed (Sys. Enz, p. 548) by Fabricius as follows: Palpi reflexi, lingua exserta, truncata. Antenne cylindricz, extrorsum crassiores— Tantalus, hylas, stellatarum, thysbe, fuciformis, apiformis, haemorr- hoidalis, culiciformis, tipuliformis. The extended description of the genus by Fabricius, and the fixing of its type by Cuvier in 1797 as sé¢e//atarum, have already been detailed at length (azéed, vol. ili., pp. 344345). Fabricius, himself, also chose the Sphingid section of Sesza to represent the genus in 1807 (see anted, p. 347). Meyrick describes (Handbook, p. 294) the genus under the name of JVacroglossa as follows: Tongue strongly developed. Antennze over $, gradually thickened to near apex, then pointed, apex slender, hooked. Abdomen broad, smooth, with broad truncate expansible anal tuft, last three segments with expansible lateral tufts. Tibie hairy. Wings wholly scaled. The genus Sesza is found throughout the greater part of the 4, BRITISH LEPIDOPTERA. Old World, and is particularly numerous in the Indian Region. The moths may be generally recognised by their strongly thickened antenne, hooked at the tip, the thickly scaled dark brown or blackish forewings, more or less coppery-red hindwings, and the undentated hind margins. The black anal tuft, too, is very conspicuous. Nearly all the species are very similar to Sesza stellatarum in size, colour, shape and general appearance. ‘Their mode of flight is too well known to need any detailed mentioning. Bartel gives ( Palacark. Gross-Schmett., i\., Pp. 213) the following table for the determination of the Palearctic species belonging to this genus : Wings scaled throughout. Forewings dark with blackish markings. 1. Hindwings sulphur-yellow, etc. .. Ae .. caudata, Brem. and Grey. 2.

Head, thorax and abdomen blackish- grey, the middle abdominal segments paler and with a pale yellowish lateral patch on either side of these segments; a black angular transverse mark behind the paler area; black and white lateral tufts to terminal segments of abdomen and black anal tuft. Anterior wings blackish-grey, sometimes with a slight ochreous tinge; an indistinct basal line, a black transverse line at some distance from base, black angulated line from costa to anal angle; a dark terminal shade, broader at apex and very narrow at anal angle; fringes of same colour as outer marginal area. Posterior wings coppery- or ochre-yellow, slightly darker at outer margin, covered with long grey scales at base ; a dark outer marginal line from apex to two-thirds towards anal angle; fringes paler, greyish-ochreous. SEXUAL DIMORPHISM.—JIn this species sexual dimorphism is reduced to a very trifling amount. The antenne in both sexes have about 52—56 joints, each carrying dorsal scales arranged in two obvious and tolerably regular rows, and with a third row close to the base and hidden (being formed of short scales) by the terminal row of the preceding segment.. The male has well-developed hairs in the ° ordinary pocket or slipper-toe arrangement of the Sphingids, the female a smooth under-surface with fine hairs. The anterior tibial spine is slightly variable, but arises in the female a little further from the base of the tibia than in the male, and is, therefore, very slightly Stellatarum, L. SESIA STELLATARUM, 5 shorter. The frenulum has been already referred to (avnfed, vol. iii.,’ p. 502). It is difficult to say that there is any sexual difference in wing colour or pattern, or in the lateral abdominal tufts. The 3 possesses, but extremely small, by the side of the 2nd abdominal segment, the fans so well developed in some Sphingids (Chapman). GYNANDROMORPHISM. — Only two gynandromorphous specimens appear to have been described. The sexual differences being so slight, great care should be taken in recording such. Those described are : a. Halved. Right side ¢, left side ¢. Right pair of wings ¢, left ¢ (smaller). Right antenna larger than the left. Right side of the body more ¢, more voluminous, left side ¢. On the abdomen traces of both sets of sexual organs present. Bred in 1896. In Hartmann coll. (Schultz, £2. Woch. fur Ent., ii., p. 395). 8. Preponderantly ¢. Right antenna ¢,lelt ¢, Allelse purely ¢. Bred along time since from a larva found near Ratibor by Hyckel. - In Hyckel coll. (Schultz, 722. Zetts. fur Ent., iii., p. 137). VaRIATION.—This species, in spite of its remarkably wide distribution, is not subject to a very great deal of variation. Bower records a specimen captured at Sandgate that measures only 30mm. from tip to tip of its forewings. Piochard de la Brulerie describes (Ann. Soc. Ent. Fr., 1863, p. 666) an albinistic aberration, the ground-colour of both pairs of wings being greyish-white, the hind tinged with yellow, and with the dark border almost typical. Mosley notes one with the hindwings very dark, and suffused with orange-brown. Oberthtr observes that the Askold examples have darker brown hindwings than those from Europe, and that the same form occurs in Japan. Strangely, Fletcher mentions that the specimens from North China and Japan are very typical. The Teneriffe examples are also said to have the hindwings somewhat deeper brown. Bartel says (Palaeark. Gross- Schmett., i., p. 217) that “aberrations have been observed in which there is a broad, velvety-black transverse band on the fore- wings. Other specimens vary considerably in the tint of the hind- wings. Thus Ochsenheimer refers (Die Schmett., iv., p. 175) to one in which the hindwings show no yellow at all, but are unicolorous black-brown ; also the one described by Herr Karl Uffeln, of Nietberg (/vis, vill., p. 170), agrees with the above specimen of Treitschke’s [ssc] in certain respects. It came from a normal autumnal larva and pupa, and the brown colour of the hind- wings extends to the whitish-mixed abdomen.” These alone are sufficient to show that there is some variation in European examples in the tint of the hindwings, and this is borne out by the specimens in the British Museum coll., where it is quite clear that local or aberrational variation exceeds manifold the geographical variation. This is exactly what might be expected with a species, individuals of which travel many miles, possibly hundreds of miles, and so must cross practically throughout their whole range within a few years. One of the most remarkable matters connected with this well-known species was its re-description by Cosmovici in Le * Caradja notes in his preface (/ris, viii., p. 2) that he wrote to Cosmovici repeatedly, asking if he could see his types or for further information, but never re- ceived a word in reply, and this, coupled with the fact that, although Cosmovici had not been able to name his Geometrids except sambucaria, he had been fortunate enough to discover two or three new Erebias, a new Theclid, and this new Jfacroglussa, in Roumania, leads one to suppose that the publication of this note is due to sheer ignorance, and is not to be taken seriously. 6 BRITISH “LEPIDOPTERA. Naturaliste, xiv., p. 280.* That it was not a specially dark aberra- tion that he named, appears clear from his note, “fort commun aux mois de Mai et de Juin.” His description reads : Macroglossa nigra (n. sp.).—Lépidoptére fort commun aux mois de mai et de juin, a vol fort rapide en plein jour et a l’ardeur du soleil. Ailes supérieures d’un noir corbeau, sans taches. Les inférieures d’un fauve roux, presque transparentes, avec la base un peu obscure et une bordure terminale fine, noire. Téte et thorax gris, fort poilus; abdomen de la couleur des supérieures. Les poils latéraux de la base de leur queue d’oiseau ont la méme coloration grise que le thorax. EccLayinc.—Of the egglaying of Sesza (Macroglossum ) stellatarum, Prideaux writes (Zt. Rec., xil., p. 268) that, from July roth-2zoth Ig00, this species was abundant on the South Devon coast where he repeatedly had the opportunity of watching it egglaying on Galum mollugo while hovering on the wing. The insect, he says, selects the top of a flowering spray as a rule, carefully examining it before depositing an egg. Rejected sprays, on being subsequently searched, were found to have been previously bespoken for the purpose; two eggs of this species were never laid on the same panicle of the plant although ova of Anticlea rubidata, and probably those of species of the genus JZe/anippe, were commonly found near those of S: stéllatarum. The green globular ege- of the latter tieqen large, is not a very conspicuous object amongst the masses of round buds of the Ga/zum, on which it is usually deposited; but it has been occasionally found laid on one of the upper whorls of leaves. The egg period, Prideaux notes, lasted only seven days. Harwood observes that the eggs are laid by the 9 on the flowers and flower-buds of Galium mollugo, that she does not alight during the process but keeps on the wing all the time, curling up her abdomen so as to place the egg on the underside of the flower or bud (Buckler’s Larvae, ii., p. 120). The eggs are laid singly, only one in the same place, on leaves and upper twigs of Szed/atae. A specimen was watched at Arcachon laying its eggs on leaves of Audia tinctorum precisely as noted by Harwood (Chapman). Laid at the junction of the pedicels of the flowerets of one of the lower lateral branches of the main spike of flowers of Galium verum,; each egg is laid on its long side, and its semitransparent green colour makes it very inconspicuous among the flowers and buds of the yellow bedstraw, and matching wonderfully well in size and appearance the young seed-capsules thereof, although it differs considerably in colour, being of a brighter and more pearly green (Bacot). Eggs laid from Novem- ber rst—5th, 1901, in confinement, at Scarborough (Head). Ransom observes that, waiting patiently by a patch of Galium verum in the hot sun, he watched a @? hovering over the flowers, neither alighting nor sucking the honey ; after a short time it selected a head, clasped the flowers with all its legs, turning at the same time its abdomen down and placing an egg on the side of one of the small unopened buds of the Ga/ium, the moth vibrated its wings very rapidly throughout the process, possibly for the purpose of supporting itself, as otherwise its weight might bear down the _ flower-head. The act of oviposition was observed on many occasions and he was thus enabled to verify his first impressions. ‘The ovum was nearly always placed on an unopened flower-bud, occasionally, however, on the under- side of a leaf (out of some 200 found, he obtained only a very small number laid onleaves). He further states that, when the flower opens, the SESIA STELLATARUM. 7 egg, if laid on a bud, is, of course, turned downwards, and the petals, though small, hide the egg; when the plant is in full bloom one might suppose that the egg had been deposited in the centre of the flower-head which, however, is not the case; if a plant be in bloom at the time of oviposition the egg is placed on the open flower ; the proboscis may be thrust into a flower during oviposition, but it is certainly the exception and not the rule. The moth appears to lay but one egg on a flower-head, but, on one occasion, he found five placed singly on a single flower-head, on another a cluster of three, and several times two, but his observation leads him to doubt their being laid by the same individual. He further notes that it is recorded that the abdomen is turned upwards when egglaying, but that he never saw any attempt whatever at an upward movement although he watched most carefully. Of five ova deposited on July rith, t901, one hatched on July 15th and four on July 16th, this giving, in this case, an oval period of only 4—5 days. Grote also notes mode of egglaying (Zool, p. 7153). Ovum.— Green in colour; almost a sphere in form; but it has a longer (micropylar) axis and a circular outline at right angles to this; the length is almost exactly 1mm. and the transverse diameter o-9gmm., some eggs are a little smalier than this, but the diameters have the same ratio; the micropyle was not made out; the surface sculpturing is in the form of a very shallow set of pits, the lines of the netting being little raised above the general surface ; the reticulation is of 5- and 6-sided pits of a diameter of o‘ozmm. (Chapman. Described November 14th, 1901, from eggs obtained by Head, of Scarborough).

Zkeretra, Kirby, ‘‘Cat..” p.,@Se stage The genus Lumorfha was founded by Hubner in 1806 ( Zenz., p. 1), and elgenor fixed as the type. Hubner places it in his tribe ii of the Sphingids, and notes: EumMorpH&—LZumorpha elpenor. He had already described and figured the species as Sphinx elpenor (Eur. Schmett., p. 61, and Larvae Lep., ii., Sph. ui, Lepaaeee figs. 2 a-6). Curtis, in 1824, fixed edpenor as the type of Dedlephila, Lasp.; we have declared edsenor the type of Zipenor, Oken; Stephens, in 1850, cited e/penor as the type of Ovews, Hb., and Westwood, in 1840, cited e/fenor as the type of JZefopsilus, Dunc., so that Deilephila, Elpenor, Oreus and Metopsilus all fall as synonyms of Lumorpha, Hb., all having e/penor as the specific type. There is a very close alliance between Zumorpha and Theretra, of which edpenor and porcellus are respectively the types. The eggs are very similar. There is, however, considerable difference in the larve in their first instar, so far as relates to the development of the caudal horn; in Z. forcellus it is merely a raised skin area, bearing tubercles i, whilst in the former it is a long dark crimson or purple bristly horn bearing i, as twin bristles, at the summit. The horn of 7. force//us has presumably been larger, and is now aborted to such an extent that, in size, it is less developed than in Dimorpha versicolora or even Lutricha quercifolia (Bacot). Chapman has already shown (avéed, pp. 58-59) that the pupa EUMORPHA ELPENOR. 61 of Theretra (porcellus) is rather more specialised than that of Eumorpha (elpenor). We further writes: “The pupa of Gurelca hyas is the only one (of the few known to me) that has any direct bearing on the curious development of spines in the pupe of LZ’. elpenor and 7. porcellus. This species has a facies very close to Sesva (Macroglossa) as an imago. The pupa, however, is much less so. It is cylindrical (not flattened) pale in colour (Eumorphid), pitted (wrinkling not advanced). The labrum is anterior, beginning to get dorsal. The pupa has, however, a peculiar ridge, just in the lines that the spines occupy in £. e/senor, which proceeds direct-to the spiracle, which it appears to enclose, but rather more as if it went round it in front than behind. The ridge is dark coloured and smooth (free from spines); in front of the anterior one (on 5th segment) the surface is transversely wrinkled in contrast to pitting elsewhere. It suggests a Darapfsa pupa that had advanced some way towards both Eumorpha (elpenor) and Sesia ( Macroglossa), with some special advance of its own.” In the imagines it may be well to notice that £. e/genor has the first joint of the palpus about 2 width of second, whilst Z. porcellus has it only about 4to4( (Chapman). Hampson diagnoses the genus (lid. Moths, i., p. 84) as: Antennz with the hook short and slight, the palpi moderately broad and quadrate at tip; apex of hindwing acute; the discocellulars oblique.

Posterior wings, outer half bright rosy-red, darker marginally, the basal half black ; cilia white. SEXUAL DIMORPHISM.—In this species the sexes are very similar. The antenne differ as is usual in Sphingids; they differ, how- ever, further, in the antenna of the @ being very decidedly more slender than that of the g; both are about 12mm. long, and consist of about 60 joints, but that of the g is about o'4omm. in diameter, where at a corresponding point that of the ? is about o°-30mm. The scaling is in three rows, the first of very short scales hidden below the last row of the preceding segment, the second is a little irregular, and the third or terminal row is more regular, and the visible portions of the scales of this row, as compared with those of the preceding row, are in length as about 3 to 2. ‘The anterior tibial spurs are larger and apparently of more complicated structure in the g. In both, the tibia is about 3°5mm. in length, and the spur is at about its middle, and so arises a little nearer the base in the 6 than in the @, vzz., in the 2 about 1:omm. fromyimemeadses in«the g o8mm.; its length is\ 15mm, im the 9) 2-2namaeeiame 3; the tibia extends beyond the spur about 1omm. in the ?, and o'6mm. inthe g. It is difficult to say that there is any difference in form of wing, colouring, or marking, between the g and @. There is, however, a somewhat different build, very obvious in living Specimens, less so in the cabinet. The 9 91s more Tobusi eae the abdomen diminishes to a sharp apical point in the last 2 or 3 (visible) segments, whilst that of the g tapers more regularly to a similar sharp apex. On the first tarsal joint of the second pair of legs there is in both sexes a close series of fine spines just opposite the larger of the tibial spines. This does not occur in Z. porcellus (Chapman). GYNANDROMORPHISM.—Only one gynandromorphous example of this species appears to have been described. This reads as follows: a. Halved, ~ Left sidé g, right side 9. ~The coloration or tae euee sides different. The left (¢) side strong rose-red; the right (¢) side on the forewing olive-green and dull red, hindwing albinistic towards the outer margin. Shape of the wings dissimilar, left longer and more slender. Left antenna male, right female. Shape of the abdomen female, though the anal point is developed ina crippled manner and glued together. Right wings 27mm., left 29mm. Bred at 3erlin.—In the Wiskvtt coll. (Wiskott, Fe stschrift, &c., pp. 108—109). TERATOLOGICAL EXAMPLE OF EUMORPHA ELPE Jan Laer notices (Ale. Konst en Letterbode, 1847, pt. 2) ee he captured an imago of £. elpenor with the left hindwing absent, but the forewing on the side where hindwing was lacking was larger than the other forewing, and showed also on its ‘ inner- -side” indications of the markings of the hindwings. VARIATION.—This species, distributed as it is over the greater part of Asia and Europe, appears to offer considerable variation, and the Indian and Japanese races have been_ respectively described as distinct species, 7vz., rivularis, Bdy. (=macromera, Butl. + /fraterna, Butl.) and /ew7szz, Butl. Besides these races EUMORPHA ELPENOR. 63 ‘there is considerable variation among the European examples, e.g., Bartel notes (Palaeark. Gross-Schmett., \1., p. 119) “that speci- mens vary greatly in size, examples smaller than Zheretra porcellus being by no means rare. An extremely interesting aberration was bred many years ago at Osnabrick from an ordinary coloured larva. This was at one time in Heydenreich’s collection, but is now in that of Wiskott. The rose colour of the forewing is entirely wanting, being replaced by an uniform chocolate-brown. The specimen figured and described by Esper (Schmett. Eur., pl. xlv., fig. 1, p. 33) may belong to a similar aberration. It was bred at Frankfort-on-the-Main, and has, besides a considerable alteration of colour and markings, also much shorter wings than normal Pee ClUpenor. This latter condition is perhaps attributable to crippling. The reddish, violet-tinged stripes of the forewings are, in this aberration, bluish-black, and the rest of the surface of the wing is red-brown, excepting the grey outer margin; the outer half of the hindwings corresponds in tint with the dark colour of the fore- wings. A further aberration is cited (/7zs, vil., p. 170) by Karl Uffeln of Rietberg. This is normal as far as to the fourth abdominal segment which, however, is black and gives the specimen a peculiar appearance. Two albinistic forms, closely resembling one another, were described (nt. Zeit. Guben, 1897, no. 9, p. 91) as follows: ‘The general impression is quite that of very bleached specimens of Eumorpha elpenor. In place of the deep green of the type, they have a light orange-yellow colour with scarcely perceptible trace of green, while in place of the ordinary dark rose colour they are pale yellowish-grey.’ On the forewings of an aberrant speci- men which is described by Schultz (//. Woch. fiir Ent., i., p. 702), the red transverse stripes and margin are much less intense in colour than in typical specimens. The normally red parts are silvery-violet, and stand out on the olive-green ground-colour much less prominently (lain lS wey A further aberration is mentioned (oc. cit., p. 706) in which the red of the hindwings is entirely wanting, being replaced by a dirty-white colour, and the right forewing is partially albinistic. Unfortunately the specimen is a complete cripple. Examples from the Amur region vary some- what amongst themselves, but agree almost entirely with European. The same applies also to specimens of £. e/penor from China. Specimens from Corea are less dark-coloured and more like the European than those from Japan.” Bartel adds that “specimens from southern and eastern Asia have received several names. Thus Butler has erected two separate species on different sexes * of the Indian specimens, but these cannot even be adduced as separate varieties, as transitions from one form to the other are present, and the two show no characteristic distinctions at all.” Herz describes a very small male from the banks of the river Wittim im montawest Siberia (/77s, XI., P. 250). Bishopp records an aberration, bred in 1870, which, instead of being of the usual olive-green and pink tints, is of an uniform grey, with just a little olive-green on the body; on June 23rd, the same lepidopterist * This is not so (see posted, p. 65), where it is stated that both sexes occur in each of the two forms. 64 BRITISH LEPIDOPTERA. records (Evt., vi., p. 485) another aberration, also bred at Ipswich, of an uniform olive-green colour, excepting the abdomen, which is tipped with bright pink. In 1871, Bond exhibited another Ipswich specimen in which the central portion of each forewing was perfectly hyaline and free from scales. It is figured and described (#77, vi., p. 81, fig.) as follows: “ The forewmes have a large central area, in which the membrane is without scales, the wing-rays only being furnished with scales, and these ochreous; the rest of the wing is smoky-brown. In the _hind- wings is a similar central area, but not so completely denuded of scales as that in the forewings; at the apical angle the wings are smoky-brown and partially of the same colour as the forewings, but the scales towards the ana] angle and nearer the centre of the wing are dull ochreous. The palpi, crown of the head and collar are dull olive-brown ; the thorax ochreous-brown, — tinged with rosy, the abdomen brown, the margins of the segments ochreous, and the tip rosy.” There is considerable minor variation in our British examples. In .many, the bright ochreous-green assumes a duller tint, and the red shades and areas on the fore- wings are of a dull purplish or violet, and much restricted in area at the centre and towards the base of the forewing, whilst the outer- margin of the hindwings is paler in colour (ab. pa/izda, n. ab.). In some examples, the outermargin of the hindwing is shaded with a tint approaching the ground-colour of the forewing to such an extent as to restrict the pinkish area to a transverse band just outside the middle of the wing (=ab. wrgafa, n. ab.), whilst in others, the outer marginal area of the hindwings is, on the other hand, some- times quite whitish. Some examples, otherwise well coloured, have no red markings at the centre of the forewings, except as a shade on the inner edge of the second oblique line, and, rarely, extreme forms have the forewings uniformly ochreous-green (= ab. wnzcolor, n. ab.). A greenish-ochreous tinge is occasionally carried over the apical area of the hindwings. On the other hand some examples have all the red markings of the fore- and hindwings brilliantly rosy-red, extending into a large patch towards the base of the forewings, and developed as an unusually broad outer marginal area on the hindwings (=ab. clara, n. ub.). Occasionally the white discal spot of the forewings is absent (= ab, odsolefa, n. ab.). The only described forms of this species are as follows: a. var. dewisit, Butl., ‘‘ Proc. Zool. Soc. Lond.,” 1875, p. 247 (1875) ; Kurby, ‘‘ Cat.,”’ p. 650 (1892) ; Bart., ‘‘ Pal. Gross-Schmett.,”’ ii., p. 121 (1900). Zdpenor, Leech, ‘Trans. Ent. Soc. Lond.,” 1898, p. 282 (1898).—/mago : Very like C. edpenor, but duller above, the rosy streaks on primaries less evident, primaries below with the golden discal patch not extending (except as a fine line) below lower radial. Expanse of wings 2 inches 10 lines, Japan. Larva: Very distinct from that of C. elpenor, brown or green. The brown larva differs principally in having the lower surface and lateral area of the last seven segments brown, with a defined, undate, sinuate internal edge, each sinuosity answering to the convex margin of its segment; the two eye-like spots are much smaller, and have pale brownish centres in both forms of the larva; the horn in the green form is longer but less curved than in the brown form. It feeds on fuchsia and balsam. [Without having seen the excellent figures of the transformations obtained by Mr. Lewis, I should not for a moment have thought this species distinct from C. e/fenor.] (Butler). 3remer and Grey (Schmetterlings-Fauna des LN. China's, p. 11) note this species amongst their list of Pekin lepidoptera, EUMORPFA ELPENOR, 65 ‘but without any remarks as to its abundance or time of appearance. Leech says (Proc. Zool. Soc. Lond., 1888, p. 584) :—‘ Except that some examples are more rosy than the type, the specimens from Oiwake, in Pryer’s collection, and others I took at Shimonoseki and Gensan in July, are not separable from C. elfenor. Localities: Oiwake (Pryer) ; Shimonoseki, Gensan (Leech) ; Kiukiang (Pratt); Hako- daté (Fletcher).” On July 8th, 1897, when we were at Gensan, I had a specimen of this species brought to me; it had been attracted to light on board. On September 13th, 1897, I found at Endermo (or Mororan), near Hakodaté, a larva, which soon pupated and I bred a fine imago therefrom. On May 8th, 1899, whilst at Chifu, I had another good specimen of this species brought to me, which seems a little darker than my Korean and Japanese examples (Fletcher). Hampson notes (Jud. Moths, p. 85) that ‘typical elpenor (= lewistz) from Europe, Japan and northwest India is smaller, with the pink on the hindwing and underside rather less developed ; whilst in the form fraterna from the Western Himalayas, the colour is rather duller and the pink on the underside more evenly disposed over the disk of both wings than in the eastern form, macromera.” 3. var. (an sp. dist.) 7:vularis, Bdv., ‘‘ Hist. Nat. Insectes,”i., p. 280 (1875).— Although the larva of this species, after Shervill’s drawing, is marbled with brown and whitish, we only doubtfully separate it from e/penor, of which it is probably only an Indian variety. At first sight it differs from e/feor in that all the rosy parts are of an obscure rosy-violet, the second oblique band of the forewings is terminated on the costal edge before the apical point, the stigmata more marked, the antennz are not rose-coloured, and, lastly, that the corselet is almost entirely olive, marked slightly with rose; otherwise, it has the same characters as e/penor. Simla, Darjeeling (reared by Mr. Shervill) ; severai in the B. M. collection (Boisduval). Butler’s two Indian Eumorphids—/raterna and macromera—are by some authors, ¢.g., Bartel, supposed to be merely the two sexes of the same Indian form, but this is not so, as both sexes occur in each of the two forms. As a matter of fact, fraterna, Btl., is identical with s7vularis, Bdv., and rivularis (=fraterna) may be looked upon as a dark-coloured variety or local race of E. e/penor, whilst macromera would seem to be merely a paler aberration of the Indian race, and approaches more nearly typical £. e/penor, with character- istics as given by Butler, both forms agreeing in having more elongated and pointed hindwings than £&. elpenor. But typical £. elpenor also occurs in India, for there is such a_ speci- men labelled “ Shillong” in the British Museum collection. There is, indeed, much to be said in favour of considering rivularis a distinct species, ¢.g., it 1s remarkable in its neuration, has nervures 6 and 7 of the hindwings more often than not stalked, and possibly has other marked characters (Kaye). On the other hand, other authors have considered the two forms as distinct varieties of E. elpenor, so that, for the use of students, we append Butler’s original descriptions : I. macromera, Butl., *‘ Proc. Zool. Soc. Lond.,’”’ 1875, p. 7.—Nearly allied to C. elpenor, but much larger; the primaries duller in colour, with the outer margin more broadly rosy lilacine; secondaries with more than half the wing rosy; body with the dorsal rosy line less defined; wings below with the costal ochraceous border duller, much narrower, only clearly represented towards base; transverse band converted into two narrow parallel lines. Expanse of wings 3 inches 4 lines, Silhet (Macgillivray), North India (Stevens). Type—B. M. coll. [Noted by Mr. Walker as a variety of C. elpenor. I am satisfied, however (from the fact that the E 66 BRITISH LEPIDOPTERA, more nearly allied Japanese species is now proved by breeding to be distinct), that it is a different species] (Butler).’ 2. fraterna, Butl., ‘‘ Proc. Zool. Soc. Lond.,” 1875, p. 247.— General aspect of C. macromera, but duller; primaries above golden- olivaceous, with the two oblique bands and border dull greyish-pink ; secondaries with basal half dull black, external half dull pink, fringe whitish ; body altogether duller ; wings below bright rese-red, costa ochreous, a central grey-brown transverse line ;_ basal half of primaries brown, clothed to first median branch with ochreous and pink hairs; body below rose-red, abdomen with lateral white dots. Expanse of wings 3 inches 2 lines. Simla (coll. F. Moore), N. India. EccLayinc.—Usually laid singly, or more rarely two or three together, on the underside of the leaves of Galium palustre, usually attached just where the leaves join the stem. Eggs found by searching at Potter Heigham, June 19th-2oth, 1896 (Bacot). Laid singly on the underside of the leaves of Galium palustre, Epilobium angustifolium, and more rarely on £. hirsutum; sometimes two eggs are found on one leaf, and once I found two in contact, but as a rule they are placed singly. Eggs found by searching, July 15th-16th, 1901, on which date, besides three smaller larve, one about three-quarters grown and another 3 inches in length were found, a sufficient illustration of the difficulty of fixing any par- ticular date for the time of egg-laying, even in a single year. The plants must be most carefully examined or the eggs may very easily be missed (Ransom). Eggs taken on wild balsam at Godalming on July &th, 1901, young larve being found on same date (Latter, 77 “i/#.). Enclosed @ ona bunch of Galium palustre, she oviposited in due course, the similarity of the eggs to the seed-pods of this plant is noticeable ; the egg-stage only lasted 7 days (Butler, zz “77.). In the Reading district the esgs appear usually to be laid two or three together on a leaf (Holland) ; laid singly at the end of June on the leaves of LZpilobium hirsutum and Czrcaea lutetiana, also, in London gardens, on the several varieties of fuchsia (Newman). OvuM.—1'5mm. in length, 1°3mm. in width, 1:2mm. in height; rather a short, rounded oval, colour green (less vivid than that of the Amorphid eggs) matching well the colour of the leaves of Galium palustre; the surface shiny ; the surface reticulation faintly but clearly marked (Bacot). Of a pale green colour, almost circular in outline, but still just a little longer than wide; the shell apparently smoo:h, but covered with a faint surface reticulation ; a distinct depression on the upper surface of egg; the micropyle is very indistinct and consists of a finely pitted depression at one end of the egg. When the embryo is fully formed, the eggshell is transparent and has an iridescent gloss (Zt. Rec., 1x. p. 237), 175mm. in length, 1°25mm. in width, oval, approaching circular in outline, somewhat flattened on upper surface; colour bright green, becoming yellow-green as development proceeds ; surface faintly reticulated, the reticulations much clearer towards the two ends, especially the micropylar, which is somewhat broader than its nadir. The micropylar depression is marked and the stellate centre is discernible (Tutt, July 9th, 1901. Eggs on Jmpatiens). The eggs are nearly spherical, but somewhat compressed, of a grass-green colour, a little lighter and somewhat larger (1°2mm.) than those of //yles euphordiae. During the development of the embryo the eggs first became yellowish-green and finally yellowish (Weismann). EUMORPHA ELPENOR 67 HaBITS OF LARVA.—The most remarkable larval habit seems to me to be the rapidity with which it reaches maturity—16 days from egg to the last stadium; it spends, however, a week or ten days in this stage, even then its whole larval period is less than a month (Bacot). Of this Garbowski observes that the larve are, in Galicia, especially fond of Ampelopsis guinguefolia, on which they are more easily and most rapidly reared, the first moult taking place on the 3rd day, and the going to earth occurring on the 18th day, after hatching. The young larve may be found by careful searching, wherever, by the sides of ditches and rivers, the food- plants show signs of being eaten; they appear to feed by day, and do not, when they get older, make any attempt to hide except when moulting, when they always appear to wander from the foodplant ; often the search ofa well-eaten plant has proved unsuccess- ful, when, two or three days later, a larva that could not possibly have been overlooked has been found on the very plant; they do sometimes, however, moult on the foodplant, and I have seen a cast skin adhering to a stalk of Galium palustre. One egg, found in 1901, hatched July 16th, the larva underwent its last moult on August 4th, was fullfed and spun its cocoon on August 14th, but did not change to pupa till August 21st. At the time of moulting the larva has all the appearance of dying, one that I observed care- fully was lying for a time on its side quite motionless, the skin turning a whitish colour, and a white line appearing along the sides; the skin broke behind the head, splitting round the latter, and enabling the larva to draw out its true legs; the larva then literally walked out of the old skin, which immediately shrivelled up (Ransom). The larve, when young, are well-hidden away in the tufts of the foodplant, but when large they often lie out exposed, and are readily seen; if you find one larva on a plant, you usually find another, sometimes two more, on the same plant (Holland). ‘The fullgrown larva rests on the twigs of Puchsza, stretched at its full length, and holding by the third pair of legs as well as by the ventral and anal claspers; the head is bent under, touching the twig, but the “Sphinx” attitude is not assumed ; viewed from the front the resemblance to a pig’s head is very striking, the head of the larva representing the flattened disk of the pig’s snout, and two ocellated spots on the 4th segment the pig’s eyes (Newman). It is well-known that the larva usually inhabits marshy places, and hence its foodplants grow by, or even in, the water. The larvae may be found, in such places, stretched at length on Galium palustre in the day, and also with a lantern feeding voraciously at night (Tutt)*. Albin remarks that there is ‘‘ something in this caterpillar very remarkable, vzz., its dexterity in swimming, for, commonly feeding in or near the water, if, at any time, it happens to fall in, it turns on its back, and swims with its head and tail turned together, till it gets hold of some part of the plant, by which it helps itself up again.” MHellins remarks that this proceeding is more like floating, unless there is a ‘‘movement to * These observations are not quite in consonance with the observations of Weismann (fosted, p. 74), who finds the younger larvze well up on the plants, the older low down upon or near the ground. 68 BRITISH LEPIDOPTERA. and fro of the head and tail.” MHarris also, in 1749, refers to the habit, and states that when a larva falls into the water it immediately rises to the top of the water, where it remains tili its struggles or the currents drive it to some plant, by means of which it can crawl out and save itself. He suggests that the swollen rst and 2nd abdominal segments contain-air that assists them to keep on the surface, and he noticed that one that had fallen into the water kept the thoracic segments above, the swollen segments being even with, the surface. Corbin notes that two larvae, carried several miles in a bottle of water by a boy, were taken out, soon recovered their normal vitality, fed up on fuchsia and pupated. Chaumette observes that the three anterior segments are extended or contracted, according as the larva is feeding, walking, or in a state of repose, and, when contracted, they are drawn into the 4th segment. The follow- ing details of the dates when larve have been observed may prove interesting: Larve are to be found from July-Sep- tember in the Linz district, 19 fullfed larve were captured in early September, 1896, at Buchenau (Himsl), two dozen larve found on Lpzilobtum in a wood at Braunfels, on August 13th, 1900 (Sich), August at Romsey (Buckell), larvae abundant from znd week in August to the end of September at Maidstone (Gandy), August 11th- 24th, 1856, larve at Cambridge (Farren), larve August 15th, 1856, spun up August 21st at Bisterne, near Ringwood (Sués., p. 20), larva. fullfed at Sherwood Forest on August 27th, 1856 (Pickard), fullgrown larva at Cuckfield on August 14th, 1857, pupated August roth (Merrifield), August 26th, 1857, larve at Ilfracombe (Mathew), August ath-17th, 1858, in Hammersmith Marshes (Gorham), September 26th, 1860 (ichneumoned), October, 1867 (ichneumoned), at Folkestone (T.

THE TERRIFYING ATTITUDE OF EUMORPHA ELPENOR. —Weismann deals at length (Studies tn the Theory of Descent, pp. 327 et seq.) with the formation of the ocellated spots in Eumorphid larve and their possible significance. He shows that the primary ocelli originate on the rst and znd abdominal segments by the detach- ment of a curved portion of the subdorsal line, this fragment becoming the “mirror,” and acquiring a dark encircling zone, “the ground area,’ the nucleus or ‘ pupil” being added subsequently. He points out that these spots make the larve more easy of detection than otherwise, and that they appear to possess a biological value as a means of terrifying their enemies. He observes that the ocellated Eumorphid larve remain quiet on being attacked, that they merely withdraw the head and thoracic segments into the swollen rst and znd abdominal segments, and that the large ocellated spots being situated on these swollen segments, the larva assumes an aspect which he shows by experiment (loc. cit., pp. 331-334) 1S most alarming to certain small birds. He concludes that the advantage of the protective coloration of such larve remains as strong as ever, and aids the concealment of the larve, that these markings are of service to the larva when attacked, and that they thus serve asa second means of defence, resorted to when the protective coloration has failed. Poulton observes (Zrans. Ent. Soc. London, 1886, p. 154) that it is specially to be noticed that the terrifying appearance due to these markings, would be effective only against an enemy approaching from the side or from above, but would produce very little, if any, effect upon an enemy advancing from the front. He points out as a fact that seems to have escaped the notice of Weismann, although it is really 70 BRITISH LEPIDOPTERA. described in his account of the larva of Z. porcellus as well as that ot LE. elpenor ( Studies in Theory of Descent, pp. 182, 187), that, when looked at from the front, a larva in this attitude exhibits another pair of ocellated marks, which appear as such in the defensive attitude only, upon the 3rd thoracic segment. ‘The “mirror” of this spot is formed by the posterior end of the white subdorsal, the ‘ ground-area ” by the black patch which encircles the former except anteriorly, but there is no trace of a nucleus as in the spots on the 1st and 2nd abdominal segments . . . and Poulton points out that, when the larva assumes the terrifying attitude and the head and thoracic segments are telescoped into the rst abdominal, the swollen anterior end of the body is abruptly truncated, and, when looked at from the front, appears as a flattish circular face marked by deep concentric furrows, which are the lines between the segments and between the annuli which are upon the latter. The result of these deep furrows, and of the shortening of the subdorsal is to render the latter, and its deep margins, inconspicuous, except in the posterior part of their length, where they become broadened, shortened, and rendered very prominent, as two eye- like marks, one on each side of the median line and towards the upper margin of the face-like extremity of the larva. Their position is, therefore, exactly that which, better than any other, produces the effect of eyes upon an enemy approaching from the front. Although the white ‘‘mirror” is not completely encircled by the ground-area, no impression of imperfection is produced and the effect of the furrows and contraction is such as not to suggest the continuity of the eyelike parts of the subdorsal and _ its margins with the rest of these markings on the anterior thoracic segments. These two eye-like marks differ from the others in that they only possess significance in the terrifying attitude, being quite unrecognisable as eyes in any other position. This must certainly add to the effect of the suddenly assumed protective attitude, when, in addition to the changed contour of the larva and the prominence given to the large eye-spots, with equal sudden- ness new terrifying marks seem, as it were, to spring into existence. Larva.—/irst instar (newly-hatched): The newly-hatched larva of £. elpenor has the head and body yellow-green in colour, the legs and prolegs paler and almost transparent; the caudal horn long in proportion to the length of the larva, black in colour, and Shghtly bifid at tip (£7nz¢. Fec., ix., p. 237).. Length on hatenme 4’5mm., pale green in colour, changing after a few hours to dark grey; segmental incisions appear as white rings, due to over- lapping of skin. Head rounded, pale green, with a few small scattered hairs thereon; slightly wider than prothorax, but not large for size of larva. Prothoracic scutellum large, but not distinct, more opaque in colour than the head. ‘Tubercles 1 and 11 on meso- and metathorax placed trapezoidally on separate sub- segments, ili 1s double on these segments, and only one subspiracular hair (v) is traceable; 1 and 11 on abdominal segments in the usual trapezoidal form, the anteriors (i) on the 8th abdominal segment being on the summit of caudal horn ; ili is a single-haired tubercle, iv is single-haired below spiracle ; each of the tubercles bears a single, very short, light-coloured seta, slightly knobbed at tip. The caudal EUMORPHA ELPENOR. 71 horn is dark purple-red, almost black, in colour, long (about one- third of length of larva), roughened, thickly covered with short spicules (a rather well-developed horn for a newly-emerged larva) ; no trace of shagreen-hairs or spicular skin-points except on the horn (July 3rd, 1896). About to undergo rst moult, length about 8mm.; colour pale shining green; the subdorsal lines, shagreen dots, and a very faint and narrow lateral line are visible through the old skin (July 9th, 1896). Second instar: Head bright green; rounded, but inclined to be tall, and somewhat square at top; division of lobes distinct; small compared with size of body; a few scattered hairs as in 1st instar. -Body bright green, but with a whitish tinge caused by the shagreen tubercles, each bearing one short hair, which put in an appearance at this stage; the prothorax and mesothorax small, the metathorax and 1st abdominal segment large, the incision between the latter very slightly marked; other incisions distinct (with exception of that between 7—8), owing to overlapping of skin; a dark mediodorsal line present, appears not to be a skin-marking, but the dorsal vessel; faint green spiracular, and stronger whitish, subdorsal lines present; the subdorsals start on either side of head, run back to the 8th abdominal, and then slope upwards to base of caudal horn; each thickens into a small lunule on the rst and 2nd abdominal segments, more strongly on the 1st; this is the first sign of the development of the marked ocellated spot of the mature larva. The caudal horn is stiff, shiny, straight, rather longer than the thickness of larva, reddish at base, black above; less rough than in 1st instar; the raised points being less like prickles and each bears one com- paratively long hair; the apex is forked, each branch bearing a rather long hair (the sete of tubercles 1); each shagreen tubercle bears a very short hair which appears to be knobbed (not forked) ; there appear to be 8 subsegments to each of the segments (July 19th, 1896; but from a different larva from that of which rst instar description was made). TZhird «instar: Length 19mm.- 25mm.; head very small for size of larva, surface dull, colour clear green, shape as in 2nd instar; body bright green; prothorax very little larger than head, mesothorax rather larger, metathorax large, though not so large as the rst and znd abdominal segments which are rather larger than the remaining abdominal segments. The head, prothorax and mesothorax, retractile; they were slightly so in 2nd instar. ‘The subdorsal lines faint on metathorax and ist and znd abdominal segments ; the anticipatory lunuiar markings of preceding instar rather higher, much stronger, of a bright cream- colour, bordered beneath with black (the black border is absent in one larva in this instar), the subdorsal band more distinctly marked on remaining abdominal segments than in previous instar, being bordered above by clear green, due to the whitish colour which spreads from the base of the shagreen-hairs, being less strong here than on the rest of the body. The lateral spiracular line has disappeared, but the oblique stripes are faintly marked, and are broad dashes like those of the larva of Sphinx ligustri, the 1st and 2nd and the lower part of the 7th are very faint, the upper part of the 7th joins the subdorsal line and is very strong; they seem to be formed as in the Amorphid larve by the massing of the shagreen G2 BRITISH LEPIDOPTERA. tubercles. The caudal horn is black, shorter than in preceding instar. Hairs very short, those on caudal horn longer than those on body; the shagreen tubercles on area of future ocellated spots are mere specks (July 12th, 1896). Sourth instar: 25mm. growing to 43mm. at end of instar ;.head, as in last instar, very small for size of larva. Body green in colour (but dark forms occur in this stadium). Head, prothorax and mesothorax now strongly retractile ; the metathorax and rst and 2nd abdominals much swollen. The dark mediodorsal line still present; the subdorsal broad, not so distinct as in previous instar, strong on 8th abdominal, and bordered with dark brown on the upper side; the oblique lines only faintly marked, although in some instances bordered with dark brown or black; the ocellated spots now strongly marked, the lunule large and bright, the upper half yellow, the lower half bright pink, surrounded by a narrow black line, on the under side this black border is enlarged into a velvety-black blotch, often with a small detached spot beneath, rather stronger on the tst than on the znd abdominal; the pink lower border of the ocellated spots in 4th instar becomes gradually surrounded by the yellow and is left as a pink lunule in the centre of the yellow one. One of the larve has strongly marked black blotches on each segment just above the subdorsal line, and a black blotch on the posterior mediodorsal portion of each segment; it is also faintly mottled with black all over the dorsal area. . The caudal horn still prominent in some larve, stiff, pointed, slightly curved, shiny, black, but with white tip (July 15th, 1896). 7th znsfar (the last): Bright green in colour, mottled with paler green specks (shagreen spots). Head rather tall, rounded in shape, very small, of a duller green tint than body, mottled with darker green on face. Pro- thoracic scutellum also darker green than rest of body. The markings on the body as in preceding instar, but rather stronger ; the spiracles dark; the subdorsal stripes on thoracic segments bordered both above and below with black (very strongly marked on anterior half of metathorax); the ocellated spots now very prominent, the central area dark greenish-brown, extending to lunule, bordered with yellow above and blue beneath, the black border very strong, especially the lower part of that on the 1st abdominal, almost equally so on both the upper and lower parts on that on the znd abdominal. [One sus- pects that the clearly-marked portion of the subdorsal line on the meta- thorax with its deep black borders is the commencement or remnant of another ocellated spot, and it suggests how this characteristic style of marking possibly originated.]| Caudal horn mounted on a pyramidal-shaped hump, the horn itself very small and insignificant (July roth, 1896) (Bacot). dlgrown larva: About 7omm. in length, stout from the rst to the 8th abdominal segment, being widest at the rst and znd abdominal segments. The thoracic segments taper rapidly to the head, which is small and round. The head, prothorax, and mesothorax can be retracted into the metathorax, which then becomes puffed. ‘There is a small, curved, rough caudal horn, 2mm. long, on the 8th abdominal segment. The skin generally smooth (Hellins), Newman also describes the fullfed larva (£77., 111., pp. 127—128). VARIATION OF LARVA.—Albin described the green and brown forms EUMORPHA ELPENOR. 73 in 1749, noting that the larve were taken on June 26th, were full- fed on July 7th, the imagines emerging on April 15th of the following year. Harris, in the Aurelian, notes the green and brown larve as belonging to different sexes, the green being ?, the brown ¢. Hellins says that, in colour, there are two main varieties: (1) This form has the ground-colour a sort of mouse-brown, buff at the folds, covered with a network of blackish freckles, except on the thoracic segments. These have a subdorsal line of dusky buff enclosed in a blackish border which, on the metathorax, swells out into a blacker blotch. The rst and 2nd abdominal segments have each, at the subdorsal level, a large blackish blotch enclosing in its upper half a lilac, kidney-shaped spot, the centre of which is olive in colour, and, at the commencement of each segment at the subdorsal level, the black freckles are more distinct and deep in tint. .The head and horn are dull black, and there is, on the 8th abdominal, a black V with its tip at the caudal horn. The spiracles are dusky buff, ringed with black. The belly is buffish, freckled with a smaller pattern than that on the back, the legs dusky. (2) The second form has the ground-colour dull green, paler at the folds, with traces of black-brown network of freckles, most distinct as a subdorsal patch on the front of each segment ; there is also a dorsal line of freckles. The subdorsal line on pieminoracie segments and the blotches on the ist and 2nd abdominal segments as in the other variety. The spiracles pale brownish, with dark rings; the ventral area dusky-green ; the caudal horn and the V-mark on the 8th abdominal segment black. Bacot observes that of six larve that hatched from Norfolk ova, all were green until the 3rd moult, and that one then obtained the dusky coloration that is usual with adult larve; in this larva the usual markings were present, but they were dark grey-brown, lighter than the general ground-colour; the black spots on each segment, just above the subdorsal lines, present, and, with these exceptions, all the other markings clearer and more distinct than in the mecamorm ) dhe remaiming five latve were green in the 4th instar, one being entirely green, three with black spots above the subdorsal band and below the stripes; the remaining one was without spots. In the black form the spiracles were white; fides ereen form black. Chaumette writes (Zool, 1x:, Pp. 3100) that the ground-colour varies from a fine apple-green to dark brown, variously variegated with small dusky lines; the dark individuals having much resemblance to the colour of the Spanish radish. The sides of the 4th and 5th segments are each ornamented with a iarge eye-like spot of a shining black colour (ocellus), on the upper half of which is a large reniform spot of a light greyish-olive colour, lighter towards the sides; also two dark oblong patches on either side of the 3rd segment, from which pro- ceed two dusky longitudinal lines towards the head; there are also faint traces of a dusky dorsal line; there is generally an interrupted longitudinal line on either side in a line with the ocelli; sometimes there are traces ot a dusky interrupted lateral line, and, often, especially in the darker individuals, there is a series of pale oblique stripes. In the dark specimens, the anterior segments are of a much lighter colour than in the others; the caudal 74 BRITISH LEPIDOPTERA. horn dark brown or black, tipped with white, with two short dark oblique stripes joining the base of it. Head, abdomen and prolegs varying according to the colour of the body, thoracic legs pale flesh colour; stigmata brownish-yellow bordered with black, but variable. James notes one nearly black larva at Deal, one brown and two green ones at Rickmansworth, one dark brown one at Broxbourne, and Russell records that larve taken on the banks of the Basingstoke canal from water-bedstraw were in various stages, some nearly fullfed, others very small; half of them were green in colour (the small ones) and half black. In confinement all the green ones in moulting changed to black and pupated when of that colour. Hammond describes (Ent., xili., p. 280) a form of the larva as: Light brown; on 5th and 6th segments a velvety-black ocellated spot, with a kidney-shaped whitish spot within the black; on the 6th, 7th, 8th, 9th and 1oth segments an oblique lateral stripe of lilac and white, similar to those in the larva of Sphinx ligustri, but shorter; horn very short. As to the cause of the dimorphism in the larve of this species, Weismann observes (Studies in the Theory of Descent, transl. pp. 296, 301) that the larve of £. elpenor, when young, rest on the leaves, but, when adult, rest by day among the dead branches and leaves of its foodplant, Zpdlobium hirsutum, and on the ground among the tangled leaves and branches if feeding on £. parvifolium. The change thus appears to be associated with a change in habit, and it is probable that this (and similarly coloured species with similar habits) first acquired the habit of concealing itself by day on the ground and among dead herbage, before the original green colour could have been changed into brown by natural selection. The adult larve are, therefore, sometimes brown and sometimes green, because the anciently-inherited green has not yet been completely replaced by the newly-acquired brown coloration, some individuals still retaining the old green colour. DEVELOPMENT OF LARVAL MARKINGS.—/i7rs¢ stadium: 4mm. in length, of a yellowish-white opalescent colour (directly after hatching), the large and somewhat curved caudal horn being black ; so transparent that (under a low magnifying power) the nervous, tracheal and alimentary systems could be beautifully seen. As soon as the larve began to feed they became green in consequence of the food appearing through the skin, but the latter also gradually acquired a dark green colour (pl. iv., fig. 17). All the specimens (20) were exactly alike and showed no trace of marking. Second stadium: The first ecdysis occurred after 5-6 days. Length of larve now 9mm.-romm., shining green, the horn becoming a little red at the base, while a fine white subdorsal line extended from the horn to the head (fig. 18). The head and legs green; the segmental divisions appear as fine light rings, the entire upper surface of the segments also crossed by fine transverse rings (as also was the case in ‘the ist stage). At the beginning of the present stage no trace of the eye-spots could be detected, but a few days after it was observed that the white subdorsal line was no longer straight on the 4th and 5th. segments, but had curved upwards into two small crescents. The latter soon stood out more strongly, owing to the filling up of their concavities with darker green. These are the first rudiments of the eye-spots (figs. 19 and 30). A very fine white 3 EUMORPHA ELPENOR. 75 - line now connected the spiracles (infra-spiracular line) and could be traced from the last segment to the head. This line takes no further part in the subsequent development of the markings, but disappears in the following stage. The blood-red colour of the base of the black caudal horn is retained till the 5th stage, and then also disappears. Before the second moult, which occurs after another period of 5-6 days, the larve, which were about 1°3cm. in length, had assumed their characteristic, tapering, slug-like form. It was not observed that the larva at this stage possessed the power of with- drawing the three foremost segments into the two succeeding ones, as is so frequently to be observed in the adults, neither were these two segments so strikingly enlarged as they are at a later period. Third stadium: After the second ecdysis the marking and colouring only undergo change with respect to the eye-spots. The concayities of the crescent-shaped portions of the subdorsal line become black, the remainder of this line at the same time losing much of its whiteness, and thus becoming less distinct, while the crescents assume the appearance of small eye-spots (fig. 20). During this stage the curved crescent-formed portions become pre- pared for complete separation from the remainder of the subdorsal line, and, just before the third moult, the eye-spots become sharply defined both in front and behind, whilst the black ground-colour curves upwards, and the white spots gradually become lenticular and commence to enlarge (fig. 21). ourth stadium: The third moult takes place after another interval of 5-6 days, the eye-spots then becoming very prominent. The white nucleus of the first spot is kidney-shaped, and that of the hind spot egg-shaped, whilst the black ground-colour extends as a slender border upwards along the sides of the spots, but does not completely surround them till towards the end of the present stage (fig. 21). The central portion of the white spots at the same time becomes of a peculiar violet- brown colour, inclining to yellow above, the peripheral region alone remaining pure white. Of the subdorsal line, only traces are now to be recognised, and these are retained, with almost unchanged in- tensity, sometimes into the last stage, remaining with the greatest persistence on the three front and on the penultimate segments, whilst on those containing the eye-spots, z¢., the 4th and 5th, not a trace remains. At the present stage, the peculiar mingling of colours becomes apparent over the whole of the upper surface, the green is no longer uniform, but a mixture of short and gently sinuous, dark green striations on a lighter ground, now appear. On the sides of the caterpillar, these stripes, which are at first indistinct but become more strongly pronounced in the next stage, are arranged obliquely on the spiracles, with the lower portions directed forwards. Fifth stadium: The 4th moult occurs 7-8 days after the 3rd, the larva being 4cm.-5cm. in length. Whilst all the specimens hitherto observed were, with one exception, light green, they now mostly changed their colour and became dark brown. In one case only did the brown colour appear in the previous (4th) stage. The striations previously mentioned appear as dull and interrupted dirty yellow streaks, the same dirty yellow colour showing itself continuously on the sides of the front four segments. Of the subdorsal line, only a distinct trace is now to be seen on the 11th 76 BRITISH LEPIDOPTERA. and on the front three segments, whilst on the 3rd segment the formation of another eye-spot commences to be plainly perceptible by a local deposition of black (fig. 23). This third spot does not, how- ever, become completely developed, either in this or in the last stage, but the subdorsal line remains continuous on the three front segments. Among other changes at this stage, there occurs a considerable shortening of the caudal horn, which, at the same time, loses its beautiful black and red colours and becomes brownish, The two large eye-spots have now nearly attained complete development. The kidney-shaped white spot has become entirely surrounded by black, and, on the brown, red, and yellow tints present in this spot during the last stage, a nearly black spot has been developed—the pupil of the eye* (fig. 33). In this 5th stage the larva attains a length of 6cm., after which the 5th moult takes place, the larva becoming ready for pupation in the 6th stage. No striking changes of colouring or marking occur after the present stage, but only certain unimportant alterations, which are, however, of the greatest theoretical interest. Sixth stadium+t: In this stage the eye-like appearance of the spots on the front segments becomes still more distinct than in the 5th stage; _at the same time these spots repeat themselves on all the other segments, from the 6th to the r1th, although certainly without pupils, and appearing only as diffused deep black spots, of the morphological significance of which, however, there cannot be the least doubt. They are situated in precisely the same positions on the 6-11 seg- ments as those on the 4th and 5th—near the front, and above and below the subdorsal line. A feeble indication of the latter can often be recognised (fig. 23). In all dark brown specimens the repeated spots can only be detected in a favourable light and after acquiring an intimate knowledge of the caterpillar, but, in light brown and green specimens, they appear very sharply defined. ‘There is one other new character never observed at an earlier period than the 6th stage— viz., the small dots which appear in pairs near the posterior edge of segments 5-11. ‘These dots cannot have been developed from the subdorsal line, as they are situated higher than the latter. Their colour varies according to the ground-colour of the caterpillar, but it is always lighter, being light green in green specimens, dull yellow in those that are light brown, and grey in the blackish-brown cater- pillars. ‘These ‘dorsal spots” are chiefly of interest because they are present in the larva of Zheretra porcellus, in which species they appear one stage earlier than in Lumorpha elpenor (Weismann, Studies in the Theory of Descent, transl. pp. 177 e¢ seq.). COMPARISON OF ADULT LARV& OF EUMORPHA ELPENOR AND THERETRA PORCELLUS.—|The larva of £. e/fenor is the younger, so that the larve are almost equal as regards size. Both larve are of the dusky form.] General coloration: The larva of &. elpenor is of a more inky hue than that of Z. forcelius, which * In order to establish a definite terminology for the different portions of the eye-spot, the pupil is designated the ‘‘ nucleus,’’ the light ground on which the pupil stands the ‘‘mirror,’? and the black ground which surrounds the mirror is termed the ‘* ground-area.”’ + We know of no other lepidopterist who has observed a 6th stadium in the larva of this species. The 5th stadium is by all considered to be the last. Weismann’s experience must have been quite unusual. EUMORPHA ELPENOR. 77 is only a greyish- or smoky-green when it is examined closely ; the general effect, however, is to give it an earthy look at a little distance; both have the darker tessellated shading, but in 7, porcellus there are no velvety-black subdorsal patches, nor is the dark shading round the ocellated spots so intensely black as in E. elpenor. Spiracles: The spiracles of 7. porcellus are pure white, those of £. elpenor have a dusky band across the centre. Ocellated spots: The ocellated spots are quite different; those of £. elpenor consist of a rounded lunule, or a bent and round-ended oblong of purple-tinted white, deepening at centre and back to greenish- sepia, the whole giving a blue effect, the spot being situated at the upper edge of a large, roughly circular, velvety-black spot. Those of Z. forcellus are less striking; the area of the black is greatly reduced by the central spot being broadened into a rounded trapezoid .of pearly-white, having, in its centre, a broad oval of dull pink that shades off centrally into a narrow oval of dull smoky-yellow. As ocellated spots, those of 7. Zorcellus are possibly the more correctly developed in plan and shading, but their dul- ness probably renders them less effective in their startling appearance than the more vivid ones of £&. elpenor. Structural differences : There seems little, if any, difference beyond the fact that there is a tolerably well-developed caudal horn in £. elgenor, which is absent in Z..porcellus, although, curiously, the white tip to the horn of the former finds its analogue in a white spot at the apex of the low elevation that replaces the horn in Z. foreellus. The larva of Z. porcellus tapers rather more towards the anal end, as though the 8th abdominal segment had dwindled slightly with the de- generation of the horn. In both species the abdominal subsegments appear to be 6 in number, the 1st being equal to the 3 or even 4 following ones in size. (This would make 8 subsegments to each segment were the rst counted as 3, as is possibly structurally the case.) Habit: Both larve have a similar slow but jerky method of moving and crawling. (Bacot. July 28th, rgor). Cocoon.— The larva spins a very slight cocoon among the rubbish below the foodplant (Ransom); the puparium is very loosely spun, composed of leaves and silk (Watkins) ; makes a slight cocoon under moss, grass or moss being interwoven with the silk (Lambillion) ; spins an open irregular but strong network of dirty-whitish silk on the surface of the soil, fastening in pieces of earth, dry leaves, &c. (Hellins). Perkins notes (£7. Wk. Int., 1859, p. 3) finding -puparia beneath pinks in a garden at Wotton-under-Edge, larve having been found on fuchsias in the same border the previous summer. Pupa.—This form is characteristically Eumorphid, fairly cylin- drical, z.e., not specially flattened; labrum anterior, a distinct keel to anterior 6mm. of maxilla, convexity of eye directed a few degrees ventrally of directly forward. Thickest part 4th and 5th abdominal segments, thinning forwards and with some little flattening in front about end of 1st legs and antenne (made more conspicuous by the maxillary keeling). The detailed dimensions of an apparently average specimen (f ) are :— 78 BRITISH LEPIDOPTERA. DISTANCE FROM TRANSVERSE | __-NTERO- BARNS SECU ES) oN ANTERIOR |DIAMETER AT bine ee EXTREMITY.

Further out and immediately in front of the eyes 1S a square prominence, ending in a rounded tubercle with one or two subsidiary ones (called eye-spines above); besides the maxillary keel, the rst tibiz present a prominent fulness in front. The antenne and rst legs terminate at about same level, the znd legs are separated from head by the rst ones touching about rmm. of the antenne. Wings and maxille terminate together at margin of 4th segment (ab- dominal). The 5th, 6th and 7th abdominal segments possess each a circle of spines, which is nearly complete on 7th, but wanting over ventral 4th of segment on 5th and 6th. ‘They are not referable to any subsegment (2.e., not obviously), they are quite to the front of the segment dorsally, are less so laterally when they le behind the spiracles and then again pass a little more forwards. In the movements of the pupa, they just touch the margin of the seg- ment in front, in extreme flexion of the pupa in any direction. Dorsally, they are smallest, but most numerous in several irregular rows, they are largest half-way from this to spiracles, whence there is no more than one row, but so irregularly placed as to quite admit of being described as isolated spines belonging to two or more rows. ‘They are black, conical, sharp-pointed, with a curve backwards. ‘They stand on the anterior slope of a ridge most marked where they are largest. The largest are perhaps ‘2mm. in length, by ‘15mm. wide at base. These spines, with the head tubercles, suggest a habit of leaving the puparium for emergence. The anterior spiracle is very obvious but has no lips or flanges of special structure, the others are narrow oval areas, with a central slit, which has raised margins and is a little wider at either end, the areas are surrounded by the ordinary wrinkling which takes, however, the form of fine concentric rings round them. When mounted as a transparent object, however, the anterior spiracle is seen to have a thickened anterior lip with many fine hairs, the posterior to be a_ flattened plate, closely EUMORPHA ELPENOR. 79 beset with minute spicules, the true spiracle is at some distance within this. The anal spine is very large and formidable, its base occupies the whole dorsal half of the 1oth abdominal segment, nearly 35mm. broad and over 1‘omm. thick, seen from above it is triangular, but not quite regularly; for the first 1°3mm. the sides approach each other slightly, then, curving in, proceed to a point; the length is 3°omm., really it is more, as when seen sideways, the dorsum is seen to be longitudinal for 2:°omm. and then to bend down at an angle of 120° or thereabouts for 2°5mm., whilst the venter is regularly curved; it ends in a very fine polished point, the extremity of which is, however, minutely bifid; beneath, it has a central ridge and two side hollows, and there is a deep grooved recess between its base and the anal eminences; it is black and covered with closely-set rather deep pits, the ridges between which preserve much of the character of wrinkling. The subsegmenta- tion is obscure, except on dorsum of the 2nd and 3rd abdominal segments, where there is a broader anterior subsegment, and 4 narrower subsegments behind it; traces of these may be seen on the other segments. Behind, and ventral to the spiracles in abdominal segments 5 and 6, may be seen, halfway between the spines and the posterior margin of the segment, the broader wrinkle, as of a wave flowing from the front backwards, since the level is lower behind it than in front, which marks off the intersegmental subsegment, which is not otherwise very obvious. ‘The scars of prolegs may be quite absent, or may be darker (more chitinised), projecting, smooth, and altering the lines of wrinkling. The normal arrangement seems to be a little extra dark pigment, with a slight elevation and hollow behind it, but no interference with the transverse lines of the wrinkling. The horn scar is equally variable. In one specimen, a little extra pigment is all that denotes it, in another it is a little raised polished circle of darker (more chitinised) colour, surrounded by a ring of minute pits, with the fine wrinkling radiating from it into the general surface, but actually domi- nating the lines on the whole dorsum of the segment. ‘There is also a very definite hollow behind the raised spot. The general sculpture or wrinkling is exceedingly difficult to describe in all these pupe. I am not sure that the attempt is not hopeless. It affords definite differences between many different species of these pupze, and yet description will hardly show anything that is not common to many of them. It is, perhaps, hardly mere sculpturing that the middle ventral line of abdominal segments 5 and 6 shows in most specimens as a longitudinal dark mark, which, in some specimens, has a depressed groove added. The prothorax appears to have a median suture which sometimes is and some- times is not functional on dehiscence; there is none in mesothorax. The head is tuberculated, rather than wrinkled, and there is almost a definite pattern within the circle of the glazed eye; the antennz have a central line and transverse impressions on either side (marking segments). The segments are separated by a fine double line, and there is indicated a line across each segment, the true wrinkling is extremely minute and secondary to these. The ridge of the maxille has a depressed line separating its two sides, and has various irregular wrinklings, on the whole transverse. The 80 BRITISH LEPIDOPTERA. legs are roughly tuberculated, perhaps, rather than wrinkled. The thorax is finely wrinkled in a “cerebral convolution” sort of pattern, without special features, except to be coarser at the wing- bases. The wings have coarse transverse wrinkling along the costa, finer and longitudinal at the hindmargin, varying in some specimens to nearly smooth ; the nervures are visible, more so at a ilttle distance as paler lines than on closer inspection. The abdominal wrinklings down to the 6th segment are of the cerebral convolution pattern, except that they are arranged to be practically transverse. On the 5th and 6th abdominals they are much coarser in front than behind the spinous ridge, with a somewhat intermediate condition on the 7th, on the 8th and gth the sculpture is largely pitting. The colour is terracotta, with a very varying amount of black. The thorax and wings, a dorsal line, and the subdorsal region are always dark, sometimes quite black. Individuals vary so that one would expect as rare varieties to see one pure terracotta. or pure black. On the thorax the sulci of the wrinklings are black, even when the ridges are pale; the same is the case with the wings and these often have black spots in rows down the nervures. On the abdomen the black especially affects the hair-spots, but is also more widely distributed. Viewed as a transparent object, the shell structure is very elaborate. The sulci in thorax and wings are marked as dark dendrites. At the wing-bases are a considerable group, on each side on meso- and metathorax, of fine hairs in minute circles or in chitinous points; these are less common dorsally. The hindwing, by the way, just falls short of the spiracle of the 3rd abdominal before being lost under forewing. The minute hair-points become more numerous on the abdominal segments and only fail on the absolute dorsal line. No definite arrange- ment of them is detected. Passing backwards, the hairs and hair- points become more numerous; when hairs are absent the hair- points are present as dark spots at the intersections of the dendritic lines of the sulci. On the final segments the pits are these same points enlarged into coin-like hollows, with either a minute hair or a hair- point in the centre. The spines on the abdominal ridges are seen to be a special development of these hair-points. Seen under the microscope, some of these are solid projeciions rising from the surface, not unlike, in colour and shape, the anal spine of the pupa. Some are then found with a deep pit under them, or rather behind them; then, in the neighbourhood of these, hair-points with hairs, but with the forward margin of the surrounding circle of chitin raised into a ridge with central point, clearly the same structure as the spine. In the course of examining the pupe, bits of fine scale became detached, and it is found that the pupa is covered by a fine scale, as in AZtmas tiliae (anted, vol. il., p. 412), most often observable on the thorax, where it is consolidated with the ridges, but passes across the valley of the wrinkling, but, when looked for, it is seen to cover the whole pupa, at least in some specimens. The anal scar is a longitudinal depression with a raised, rather broad, lip surrounding it, with parallel impressed lines, The lips pass round the posterior end of the depression and over- hang the cavity at the base of the anal spike. Anteriorly they rather fade out into the general surface. There is considerable EUMORPHA ELPENOR. 81 difference in their disposition, sometimes the lips with the central line as depression occupy a circular area, more often it is narrower, 7.é., elliptical, and sometimes, by the sides being nearly parallel, it is rather quadrangular. The small angular portions of the roth segment not occupied by the scar and spike are strongly pitted, but usually without special feature ; rarely, close to the posterior angle of the anal scar, there is an irregularity that may be the scar of the larval claspers. The male tubercles are full and rounded, occupy an exactly circular area, with the median crevice between them; this is a little wider posteriorly. Though in the middle of abdominal segment g, these male tubercles have the appearance of belonging to 10, as the posterior border of 9 1s wanting opposite them, ze¢., appears to bend up to them, and may more easily pass round them in front than behind. Precisely similarly the segmental divisions are wanting im the Same parts in the female pupa between 8, 9, and 10; 9 presents a few wrinkles, which pass back to the anal scar, and the margin of 8—g passes forwards to the posterior pore. This is very similar to the male pore, but on a much smaller scale; in front of this is, less marked but quite distinct, another longitudinal impression; the area on 8 occupied by these two pores and their accessories 1S a square with its diagonals longitudinal and _trans- verse, and from its lateral angles a line passes outwards and fades into the posterior margin of the segment (Chapman). PupaL Hapits.—The pupa of Z. e/penor is remarkable in that it is able to work its way out of its cocoon before emergence in the same way as does the pupa of Dimorpha versicolora. ‘This is effected by means of the spines already described (anted, p. 78) as existing along certain of the abdominal segments. Bacot notes that he had larva, in 1895, that pupated in a flower-pot filled with moss, and formed long and rather narrow cocoons by spinning the moss stems together with a small amount of silk. These cocoons were all vertical, or nearly so, and were from half-an-inch to an inch longer than the pupa, the top being usually left open; in the spring the pupze were observed to move up and down in their. cocoons, and one, in particular, used to push itself half-way out on sunny days, going down again in cold and dull weather, and it was halfway out of its cocoon when the moth was disclosed ; some moths, however, emerged from pupe that had their heads only protruding, while, in other instances, no movement on the part of the pupa had apparently been made before emergence. Ransom observes that, about a month before emerging, some pupz work their way Out of the cocoons and travel several inches away from the cocoon ; the movement is accomplished by means of strong spines on the abdominal segments; the abdomen is moved from side to side, and the spines, catching hold of any substance with which they come in contact, enable the pupa to progress. Russell notes that as early as May 14th, the pupe (which remained in the moss in which the larve had pupated) prepared for emergence. They raised themselves on end, and, in many instances, stood out of the moss practically upright, although about one-third otf the pupz eppeated ft0 make no movement at all. A note in the Zvz7. Wk. Int., vii., p. 109, states that a pupa worked itself out of its loose cocoon, and lay quite bare on the moss for 5 or 7 weeks before F 82 BRITISH LEPIDOPTERA. the emergence of the perfect insect. Bacot observes (z# Jit.) that he has immersed pupz of this species in water for periods of a few hours up to 23 days, and that they have all survived. FooppLants.—£pilobium angustifolium, Impatiens, Vitis, Convol- vulus (Linné), Galium palustre, Epilobium hirsutum (Buckler), Menyanthes trifoliata (Huene), Galium mollugo, Fuchsia, vine (Hellins), variegated holly, Fuchsia fulgens (Hodge), Galium verum (Riding), LEpilobium palustre (Lambillion), mpatiens nolt-me-tangere, Circaea lute- tiana (Crewe), Vitis vinifera (Calberla), Rubia tinctorum (Snellen), Lythrum salicaria (Krieghoft), Lpilobtum parviflorum (Weismann), Lythrum purpureum (Poulton), Czrcaea intermedia, Ampelopsis hederacea (Rossler), A. guinquefolia (Garbowski), /mpatiens parvifiora, Balsamina repens, Lonicera (teste Bartel), lettuce (Vaughan, £77, xxxiv., p. 100), apple (Thornewill). Bacot observes: ‘‘ The larve eat Fuchsia well in captivity; in nature (in the Lea valley) they appear to commence on Galium palustre, and after they have finished this they attack the Lf7/obium, on the top of a tall plant of which they are sometimes very conspicuous.” Ransom notes: “The larve eat Galium palustre and various species of Efpzlobium, but E. hirsutum much less frequently than the other species.” Russell writes: “The larve eat fuchsia greedily, but some I had did not fancy one plant that had reddish-coloured leaves.” At the meeting of the Ent. Soc. of London, November 19th, 1902, Mr. Goss stated that in August, 1898 and 1899, he collected a number of larve of Eumorpha elpenor feeding on Jmpatiens noli-me-tangere, that, when this was exhausted, he offered them L£7lobium hirsutum, Fuchsia, Galium mollugo, and G. aparine. ‘The larve refused to eat any of them, and many of the larve (nearly three dozen) died of starvation before a fresh supply of /mpatiens could be obtained. PARASITES. — Amblyteles proteus, Christ (Bignell), Amdlyteles JSusorius, Linn. (Brischke), /chneumon privenis (Harris). Hasirs.—The imago usually emerges in the morning about 9 a.m. (Hewett). Both sexes fly to flowers at dusk, flight not lasting long (Ruhl), and they may then be sometimes taken in large numbers. They affect the flowers of Saponaria, Lonicera, Echium, Petunia, &c., in Germany (Bartel), flowers of Syringa and Lonicera caprifolium in the Baltic provinces (Nolcken), but are attracted by many other flowers—Turk’s-cap lily at Armagh (Johnson), rhododen- dron, swarming in scores at one small bush at Dinas Mawddwy (Tetley), also abundant at the same plant at Lissan (Greer), garden- rocket (Ash), Galium (Sich), J/ris pseudacorus (Barrett), Cerasus lusttanica (Oldham), at violas at Bushey Heath (Barraud), at Aconitum napellus, abundant at St. Clerans (Lawless), white pinks and valerian at Sulby (Clarke), different varieties of garden /ris are particularly attractive at Clevedon (Mason), whilst honeysuckle is repeatedly noted from various localities. ‘The moth is also attracted by sugar. We shall never forget one dark evening in June, 1874, at Cuxton, when rain came on at dusk, directly after the sugar had been put on the trees; Noctuids swarmed, but the appearance of several splendid imagines of Lumorpha elpenor, drinking steadily at the sugar on quivering wing, proved the excitement of the evening. Comes freely to sugar at Sulby from about - June goth (Clarke), buzzing at the sugar at Barnwell Wold, also at Abbott’s Wood in EUMORPHA ELPENOR. 83 1892 (Porritt), at sugar at Gravesend (Button), in Wicken Fen (Musham), in the Wye Valley (Vaughan), at York (Wilson), at Llanrwst (Pearson), at Ranworth (Harmer), hovering at the sugar in south Devon (Prideaux), a fine g at sugar, July rst, 1897, at Benfleet, quite settled on it and not flying round (James), June 24th, 1899, and July rst, 1900, at Bude, at sugared J7ss, and on June 12th, 1900, at Wicken, at a sugared treetrunk (Kaye), Hervey notes 4 specimens at sugar at Glastonbury, June 22nd, 1875, three hovering at one tree, and taken by one sweep of the net; they arrived comparatively early in the evening, before the lamp was lighted to examine the sugar. Burrows observed one hovering at sugar, June roth, 1896, at Rainham; the light was kept steadily on the insect, whilst a larger box was fetched; it took no notice of the light, but went on drinking. ‘Trimoulet also records the insect at sugar in the Gironde dept. The imagines are also attracted to light—at the electric lights at Bern (Hiltbold), at Portschach (Wagner), most abundant on July g3rd-4th, 1898, from 9.15 p.m.—1iIo0.20 p.m., at Aigle, at the electric lights (Lowe), also at electric light at Eastbourne (Dewey), at Ipswich (Morléy), at Chester (Dobie), at light at Taunton (Farrant), at Paul (Daws), at Erith (Fenn), at Winchester (Shepheard-Walwyn), &c. Smith fees 2 9 captured-by a friend at Exeter, carried to Burton alive in a box in pocket, and states that, while waiting near Chelten- iaumed § settled on him (£z/., xxix., p. 124). Time of day and other details are altogether wanting. Hapitat.—The imagines visit gardens, roadsides, woodsides, &c., attracted no doubt by the flowers, and their larve are occasionally found in such localities, but fens, ditchsides, river- banks, streamsides, pondsides, and similar localities are their favourite haunts. The.larve are sometimes abundant on all the ditchsides between Sandwich and Deal (Tutt), ditchsides at Folke- stone (Byrne), on the banks of a pond at Oxton (Studd), along the banks of the Stour near Ashford and Wye (Theobald), on the banks of ditches and by the riverside near Sudbury (Ransom), along the banks of streams and ditches at Maidstone (Gandy), abundant in the water-meadows at Newbury (Hopson). Thornewill records finding a larva in a garden at Burton on apple; Perkins finds the species sometimes common in gardens at Wotton-under- Edge, and Calberla states that the larve are abundant in the vineyards of the Roman Campagna. TIMES OF APPEARANCE.—In the British Islands the species is single-brooded, occurring generally in late May and June (extending in late seasons into July), whilst the appearance of autumnal examples is very occasional. We have only noted the following records, zz., reared a second brood through August, 1859, at Lancaster (Taylor). Several larvze obtained in July at Oxford, pupated in due course, two pupe producing imagines on August 5th, 1868 (Matthews), Sep- tember 12th, 1878, an imago at Taunton (Parish), August 13th, 1879, at light, at Erith (Fenn), a second-brood 9 example emerged September 15th, 1900, at Sudbury, from a pupa that was in the pupal stage a very short time and which was of a very pale colour (Ransom). On the continent complete or partial double-broods are common. ‘Thus we find—end of May and commencement of 84 BRITISH LEPIDOPTERA.

In 1835, Stephens placed this species in his ‘ Abstract of the Indigenous Lepidoptera contained in the Verzeichniss Bekannter Schmetterlinge” (Illus.

Museum, pt. v), but the name is, by a printer’s error, misspelt PArynus. The genus has been diagnosed (zz J/i#t.) at length by Kaye as follows: Forewing triangular, pointed sharply at apex; exterior margin very slightly convex, not indented. Cell extending half the length of wing, nervures 7, 8 on a long stalk, 6 from upper angle. Cross-nervure very oblique and slightly curved ; nervure 5 slightly nearer 4 than 6; nervure 2 two-fifths from base; 10 greatly curved up after leaving base and returning to extreme angle at tornus. Hindwing rather short and broad, apex very bluntly pointed; exterior margin recurved and bluntly pointed at anal angle; cell scarcely extending more than one-third length of wing; subcostal spur emitted at less than half the length of cell; 6 and 7 from upper angle, 6 almost straight. Discocellular flattened, S-shaped, with both curves about equal; nervure 3 from close to 4, 2 from half the length of cell. Palpi blunt. Antenne with pectinations very weak, consisting only of a few hairs— Phryxus livornica. Weismann shows (Studies in Theory of Descent, p. 200) that fivornica and lineata (referred by Staudinger, Caz, 3rd ed., p. 103, to the same species) fall in separate groups when considered from the point of view of larval development. From this standpoint he differentiates them as having : Open ring-spots + appearing on the subdorsal line on all the segments from the 11th to the tst—déneata. Closed ring-spots situated on the subdorsal line -Z/vornica. Later, however, he shows (Joc. ci?., p. 358) that he considers the larva of dimeata to be an ancestral stage on the same line of descent as that of “vornica, the former being the more generalised, the latter the more specialised, member of the same genus. The pupa of LP. divornica differs from the other Phryxid pupe known to us in being much more like that of Aippotion than they are. It has a certain amount of antero-posterior flattening, whilst the other Phryxids are fairly round ; it also shows some S curve owing to ventral lengthen- ing of abdominal segment 4, the others being fairly straight; the maxillary keel is long and thin, extending round front of head, * This was the Accipitrina livernica of Petiver, 1702. The name, however, has no standing on Petiver’s authority, being antecedent to 1758, the earliest date accepted for binomial nomenclature. t Fernald’s description /fosted, p. 150) suggests that certain forms of this larva may reach or even surpass that of ¢¢7ernica in the development of its ring-spots, “-PHRVXUS LIVORNICA, 147 making the labrum dorsal; the anal spike is comparatively slender and short. All these are rather Hippotionid than Phryxid characters. As a character of its own it has the rough prespiracular area of 5, 6 and 7 much more extended than in any other Phryxid, or indeed any other Sphingid, pupa I know. The texture is Phryxid, but its sculpturing is more pitting than in other Phryxids, which one would hardly expect, since it appears to be in pupal development the most advanced of them (Chapman). The following is our own general diagnosis of the genus (as restricted to Zivornica and lineata): IMAGO: Head large, prominent, projecting; forewings long, pointed, with an oblique streak running from apex to close to base; nervures clearly marked by light scales; abdomen very tapering; front tibia with very strong spines and some weaker Ones. PupA: Labrum anterior; keel well-developed; sculpture largely pitting. LARVA: Of typical Phryxid outline, with a single row of open or closed ring-spots on the subdorsal line. It is a most restricted genus, with only two species, /vornica and dneafa, but these have an almost world-wide distribution, the former occurring almost throughout the whole of the Old World, including Australia, and the latter, a great part of the New World, including the Pacific Islands.

Er ist Tab. viii, fig. 4, abgebildet, und pag. 87 und 88 beschrieben (Esper LZuvop. Schmetterlinge, &c., i., Pp. 196). The description here referred to reads as follows: ‘On pl. vii, fig. 4, Sphinx .livornica, a separate species is addedimren comparison (with S. ce/erzo). In the Systema, we are referred to a figure of Petiver’s (Petiver,.Gaz., Lab: xii, fig: 9, oper. Tompiiyamate ‘Accipitrina livornica, perpelle striata. From Lisbon, caught flying about a candle in October, 1698. Its eyes, whilst alive, are like rubies. It frequents the jasmin flowers.’ The description, which we quote, is too defective to judge from. Nothing further is said than that it had been previously found at Leghorn. The figure which Petiver gives differs considerably from Rosel’s. It has not the same wing-contour, it is smaller, the body broader, adorned with series of white spots. Neither the curved lines nor the black spots are shown in Rosel’s fig. These were differences enough to excite doubts. Much more nearly in agreement with this figure, I found the moth which is figured, from an original example, at fig. 4 of the present plate. On comparison with this, Petiver’s Papilio will be less of a puzzle. We see in both the same traits of contour and markings. The original of this 4th figure on our plate is likewise from Italy. This species has never yet been found in Germany. One of my friends, Herr Pastor Lips, of Petersaurach, obtained it by exchange from an entomologist of Verona. It it peculiar to the warmer parts of Italy, and may thus also, to judge from the similiarity of climate, really occur in Portugal as Petiver says. In the accompanying plate it is, on certain grounds, only noted as a variety of celerzo,as which it is possible to regard it, but the difference is too considerable to give one grounds for asserting this. I think I shall lighten my readers’ labours if I present it for comparison with Rosel’s ce/evzo, and at the same time point out its similarity to Petiver’s figure. It does not admit of being dealt with as a variety, but deserves a separate name. I retain the first, the oldest name, which Petiver gave it, Sphinx livornica. I only regret that I am not able to add anything further of its natural history. I have already said all that I can about it. Its difference from Rosel’s ce/erio is considerable. The nervures running through the wings are here not black, but white. The whitish-coloured streak which runs through the wings longitudinally is in this, as in that, species, divided by a central black line. It is unicolorous, not so strongly curved, but straighter, broader and — more direct than in that species. The hindwings are only pale * Figured by Esper in 1779 (Schmett. Eur., pl. viii., fig. 4) as a var. of fH, celerio. Described in 1780 (doc. cit., p. 87) by which time Esper had come to the conclusion that it was a distinct species and named it Jdivornica. About 1800 (Zoc. cit., cont., pl. les figs. 3-7) he figured it again, in its early stages, after the figures in Fuessly’s Archiv, PHRYXUS LIVORNICA. 149 red, not divided by black nervures and spots. Along the body also there are not the connected white lines as in the former species. Here they consist rather of rings of alternately white and brown oblong squares. ‘The figure will enable further comparison” (Esper, Schmett. Eur., i., pp. 87-88). ImMaco.—7omm.-75mm. ‘Thorax olive-brown, with 4 white longitudinal lines, the outer passing from the front of head, through base of antennze to base of hindwings. Abdomen olive-brown, a white median longitudinal line, black and white banded. Anterior wings olive-brown, with moderately wide oblique creamy fascia crossing the forewings from apex to inner margin near base, becoming white at the inner margin; the outer marginal area (slightly purple-) greyish; the nervures raised, creamy-white, but ‘not pale-coloured within the subcostal and outer-marginal areas ; a small triangular white discoidal patch contains a minute black dot ; innermarginal edge white; fringes creamy, suffused with blackish at ends of nervures. Posterior wings pink, with black base and black submarginal band; outermarginal area pinky-grey, suffused with black scales; a white patch at base of pink median band ; fringes white. SEXUAL DIMORPHISM.—The @ appears to be distinctly larger than the g, a fact often, however, obscured, as it is much within the limits of individual variation in size. Besides the ordinary difference between the g and @ antenne in Sphinges, that of the male is maimestie longer, 13°5mm. and 12-5mm-. respectively. The. 1st tibia of the g seems slightly longer than that of the ?. The Ist tibial spurs are almost exactly equal in length in the two sexes, and there is little if any difference in the development of the comb. The g possesses a scent fan at the base of the abdomen, but it is so small and ill-developed that I have been unable to find it without macerating and mounting the specimens. It is a minute wisp of hairs, the longest about 2mm. in length, arising from the external anterior angle of the first ventral plate of the abdomen, its usual site when so restricted. The baton-like scales fringing the segments, so characteristic of all Sphingids, are here, as in other Phryxids, large and in several rows, or at least of varying sizes. VARIATION.—Oberthiir notes that the species varies much in shape and intensity of coloration. Lucas says (Lull. Soc. Ent. Fr., 1880, p. ]xviil) that the Tunisian specimens resemble those of southern Europe, except that the colour is richer, and the red of the hindwings clearer, otherwise they are quite comparable with Algerian examples. Bartel says (Fal. Gross-Schmett., \i., p. 100) that the light yellow colour which occupies the middle band varies much in intensity, the enclosed oblique dark band thus being sometimes narrower, at other times broader; it is sometimes dirty yellow- brown. The hindwings also vary much in colour and markings. Bartel further notes that a g from Serach (on the frontiers of North Persia and Turkestan) is very small, only 48mm. in expanse, and altogether of a paler colour than any other specimens examined. A very dark example (especially on the underside), from Sikkim, is in the Kricheldorff coll., Berlin; in this example, the costa of the forewings on the upperside is very broadly dark. In Australia, P. livornica occurs as a dwarf form (var. australasiae, n. var.), but 150 BRITISH LEPIDOPTERA. is undoubtedly this species, and not P. “neata, which occurs in the Hawaiian Islands. -Tne Western Australian examples have also more rounded wings. Kaye states (zm U¢t.) that the main variation of this species occurs in the width of the black submarginal band of the hindwing, and the width of the brownish band between this and the outer margin. ‘This is considerable, the Australian specimens having this brownish band quite broad at apex. ‘These latter also have the markings of the abdomen rather reduced, but, perhaps, not much so considering their smaller size. PHRYXUS LIVORNICA AND P. LINEAtTA.—Our Palearctic Phryxus livornica, Esp., has, by many authors, been considered as co-specific with the Nearctic P. Zéneata, Fab. (commonly known as daucus, Cram.). Not only are the imagines markedly different, but the larva of P. lineata is very different from that of P. “vornica, being the phyletically older (see Weismann, Studies in Theory of Descent, pp. 216-217), but, if one compares the larva and pupa of P. “émeata (Abbot and Smith, Nat. Hist. Ins. Georgia, pl. xxxix) with those ~of “2 v/ivg7azee (Hubner, SfAznges ii., Legit., B.c., figs. 1a—c), one is convinced, as both are apparently well drawn, that they belong to different species, and one cannot follow Staudinger (Cazalog, 3rd ed., p. 103) in considering “ivornica, Esp., a variety of d:neafa, Fab. Kirby states (L£nt., xxvil., p. 165) that Barrett (Zep. Brit, ii., p. 46) curiously notes P. /ineata as a variety of P. “ivornica, and then, in the next paragraph, treats the former as a distinct species under the name of daucus. Vhe original description of /ézeata reads as follows :— Sphinx alis virescentibus: fascia striisque albis; posticis nigris; fascia rubra. Habitat in America. Statura pracedentis. Caput virescens, stria laterali alba. Thorax virescens, striis tribus albis duplicatis. Abdomen cinereum, albo nigroque maculatum. Alze antivee integerrimee, virescentes, fascia media striisque sex fasciam secantibus abbreviates, albis. Margo posticus cinerascens. Ale posticze atree, fascia media lata rufa; subtus omnes cinerascentes, atomis viridibus (Fabricius, Syst. Lintomologiae, pp. 541-542). LARVA: The mature larva is about 3ins, long and quite variable. The most common form is of a yellowish-green colour with a row of prominent spots along each side, each spot consisting of two curved black lines en- closing a crimson patch above and a pale yellow line below, the whole being connected by a pale yellow stripe edged with black. In some instances these spots are disconnected, and the space between the black crescents is of an uniform cream- colour. ‘Lhe other form of the larva is black with a yellow line along the middle of the back, and a double series of yellow spots and dots along the side. Caudal horn yellowish-orange towards the extremity and rough (Fernald). Pupa: Light brown, the head-case compressed laterally and prominent; tongue-case not apparent (Clemens). FooDPLANTS: Apple, grape, plum, currant, gooseberry, buckwheat, turnip, water-melon, chickweed, Rumex obtusifolius, @nothera biennis, Portulaca oleracea (Fernald). DisTR1BUTION: North and Central America, West Indies, Pacific Islands. Oberthur and other authors note (zz litt.) that /zneata, Fab. (daucus, Cram.), from America, is a valid species. It always has six white stripes on the thorax, whilst the European @vornica, Esp., has always only four such white stripes. EGGLAYING.—No note on the egglaying of this species in nature appears to have been published. Eggs, laidin confinement, by 2 moths captured near Exeter, were light green, and glued to flowers of red valerian which had been placed for the sustenance of the moths. The egg stage lasted about three weeks and twelve young larve were obtained (Hellins, £.47.17,, vu., p. 102). A 92 captured at Bromsgrove on May 31st, 1870, laid 15 eggs (Enock). OvumM.—Apparently undescribed except as above. PHRVXUS LIVORNICA. 151 Hapits OF LARVA.—The larve of the summer brood usually emerge from the egg in June and feed up through that month and July, pupating from about the middle of July until August, but Bellier-de-la-Chavignerie notes that he found larve feeding on Rumex acetosella in June and July at Florac, at the same time that imagines were observed on the wing. The larve are more or less polyphagous, and Boisduval observes that they are often found in France by the sides of the roads and in fields, on plants that are not at all nearly allied, and that they are often recorded as feeding on the tender succulent shoots of various kinds of fuchsia, e.g., Gouley took one on fuchsia at the beginning of July, 1866, at Calvados, the example pupating and the imago emerging on October 3rd, whilst Lucas found some on fuchsia in the gardens of the Parisian suburbs, in 1856, &c. Godart records larve captured, in the latter year, on Galium verum, at St. Cloud, whilst Allard remarks that they are not rare on Euphorbiaceae at Biskra, where they are larger and brighter than those taken in mid-France. Rambur notes (Cat. Lép. Andal., p. 131) the larve as being almost polyphagous and sometimes so abundant in the plains of Malaga, along the fields, that one may collect some hundreds in a short time. . Chaumette records the larva on vine on June roth, 1846, on Les Mousquines, near Lausanne. In Sicily the larve are said to feed almost entirely on vine, and Milliere observes that those of the first brood are fullfed at the end of June, and, as the pupal stage lasts only about a fortnight, the imagines emerge about the middle of July. Very few larve have been recorded as taken in the British Islands. 137, plo xvil.. tig-3.(6-7c) (O22) eee “Kur. ep. Imd. Meth.,’” p: 33 (1829); Meig... *°ur.

The genus Ce/erio was described (Lehrb. Zool., i., p. 761) in 1815, by Oken, as follows : Halbbandierte, halbringleibige Schwarmer ; Fleckenraupen. Zarva_ with small, globular, not retractile head, body smooth, a caudal horn, coloured lateral spots. /upa on the earth among leaves. /mayo with interrupted rings on the sides of the abdomen ; tongue longer; forewings elongate, smooth-margined, inner margin hollowed ; antennz of almost uniform thickness, scaled beneath, apex thread- like—Celerio gallit, euphorbiae. The genus is, according to the showing of Weismann (larve) and Kaye (imagines), heterotypical, and we fixed the type of the genus (az/ed, vol. ill., p. 355) aS gallit. Kaye makes (7 Jitt.) gallit the centre of a small group of Phryxids, which he defines as follows : Head not prominent, nor markedly projecting; forewings not so long as in Phryxus, and less pointed; with oblique band from apex to near base giving off two or more short teeth or branches; spines on front tibia nearly all of uniform size—Celeriv gallii, euphorbiarum, zygophylli, ? opheltes. This he has now supplemented (zz /¢/.) by a more detailed diagnosis, which reads: Head not large, nor markedly prominent, but fairly pointed. Palpi bluntly pointed, ‘Thorax broadest at costal base of forewing. Abdomen not long, tapering rapidly from the 4th segment to tip. Forewing of medium length, the costa straight to beyond the origin of 7, then very slightly curved, and finally sharply curved to apex. Outer margin slightly curved from apex to nervure 5, then straight to termen. In the ? the margin is straighter. Inner margin curved very slightly inwards soon after leaving termen. Nervures 7, 8 stalked, 9 from two-thirds length of cell, Cross-nervure of cell evenly curved inwards. Nervure 2 from well before half length of cell. An oblique band from apex to near base giving off two or more short tooth-like marks. Hindwing with.costa evenly arched, apex very blunt; outer margin evenly curved to nervure 3, thence to nervure 10 considerably curved inward, forming a fairly sharp point at the extremity of nervure ; CELERIO GALLII. 169 from 10 to anal angle straight. Cross nervure between 7, 8 evenly curved, given off from less than half the length of cell; nervure 8 approximated to 7 just beyond the cell; 6 and 7 from upper angle; 5 almost equidistant from 4 and 6. Cross-nervure of cell forming a well defined S. Spines on front tibia nearly all of uniform medium size—Ce/erio (type galliz. Weismann, on larval characters, does not quite get the same grouping as that suggested by Kaye. He notes (Studies in Theory of Descent, p. 224) the larve of the species of this group as being in what he terms the 6th phyletic stage, in which the larva has— A single row of ring-spots replacing the subdorsal line. Although Zhaumas vespertilio and Hyles mauretanica fall into the same (7¢., the 6th) phyletic stage of larval development, we find (loc. cit., p. 358) that Weismann does not consider that they belong to the same genus as Ce/lerio galliz, but he isolates the latter as a terminal form on its own particular evolutionary line. He also considers zygophyllz (grouped with gall by Kaye) as a terminal form on another line of development. CELERIO GALLII, von Rottemburg.

Es ist dieses derjenige dem Sphinx elpenor so ahnliche Vogel, dessen der Hr. Hufnagel in der Anmerkung erwehnet, und dessen Beschreibung ich schon oben versprochen. Die Raupe desselben hat Rosel, tom. iii., tab. vi., figs. I, 2, 4 abgebildet. Er halt sie aber fur eine blosse Varietat der Wolfmilchraupe, und sagt, dass der daraus entstehende Vogel jenem vollkommen gleich, nur etwas dunkler sey. Allein so ahniich dieser Vogel dem Sphinx euphorbiae ist, so unterscheidet er sich dennoch bey genauerer Betrachtung deutlich von ihm. Die dunkel- olivengrune Farbe am obern Rande derer Oberfliigel, macht nicht wie bey jenem einige abgesetzte Flecke aus, sondern nimmt als ein breiter gezackter Streif den ganzen obern Rand ein, und gehet von der Einlenkung bis zur Flugelspitze. Das Rothe derer Unterfligel ist nicht so lebhaft, wie bey dem Sphinx elpenor. Die Unterseite aller vier Fligel ist allemal bey dem 5S. e/penor rosenroth, oder doch rothlich, bey diesem Vogel aber siehet man nichts vom Rothen, sondern die ganze Unterflache ist hier blass Olivengriin, oder vielmehr fahl, und die dunklen Flecke der Oberseite scheinen deutlich durch. Auch die Raupe ist sehr von der gemeinen Wolfmilchraupe ver- schieden, welches ein jeder aus der roselschen Abbildung wahrnehmen kann. Selbst an der Puppe zeigt sich eine Verschiedenheit, indem solche viel dunkelbrauner ist, als die Puppe des Sphingis esulae. Zu diesem allen kommt noch das verschiedene Futter derer Raupen. Die gemeine Wolfmilchraupe habe ich niemals, selbst durch Hunger dahin bringen konnen, dass sie von dem Gadlzio etwas gefressen, und die Raupe unseres jetzt beschriebenen Vogels, die sich bloss vom Gadlio nahret, habe ich niemals zum Genuss der Wolfmilch bringen konnen. Sonst leben die Raupen zu einerley Zeit, auch 170 BRITISH LEPIDOPTERA. kriechen die Vogel zu einerley Jahreszeit aus. Doch sind mir Ao. 1771, 2 Stuck von dem S. galdi vier Wochen nach ihrer Verwand- elung ausgeflogen, nemlich im Aug. da die Raupen sich erst im Julio verwandelt. Es ist dieser letzte Vogel und seine Raupe ziemlich selten, und ich habe in keinem Jahre mehr als ein, hochstens zwey Stuck davon gefunden, da’ hingegen die Wolfmilchraupe in hiesiger Gegend sehr haufig ist. Alle diese Umstande zusammen genommen, scheinen mir genugsamen Grund zu geben, diesen jetzt beschriebenen Vogel nicht fiir eine blosse Abanderung vom Sphinx euphorbiae, sondern fur eine besondre Art zu halten, und ich nenne ihn daher nach dem Futter der Raupe Sphinx gall (Rottemburg, Der Naturforscher, Vii., pp. 107-108). ImMaGo.—62'5mm.—gitmm. ‘Thorax deep olive-brown, with white lateral lines from front to end of thorax, edged above with blackish ; abdomen deep olive-brown banded alternately with black and white towards thorax and ringed with white towards anus, a median longitudinal dorsal row of white spots. Anterior wings deep olive-brown with a moderately wide oblique ochreous fascia from apex to inner margin near base, curved as it approaches inner margin, pointed towards apex, and extending somewhat wedge-shaped towards base, two irregular extensions on upper edge, one at end of discoidal cell, the other midway between this and apex; outer marginal area purple-greyish ; fine inner marginal line white; basal patch of white scales ; fringes unicolorous, dark ochreous-brown. Posterior wings with black base; central band creamy-pink, becoming quite red where it meets the white basal patch; black submarginal band (variable in width); outer marginal area pinkish-grey, speckled with dark scales ; fringes white. SEXUAL DIMORPHISM.—The @? tends to be the larger, but there is very little difference in the general build, the more slender aspect of the g is obscured in cabinet specimens by the contraction of the segments. The antenne are longer in the g. The anterior tibial spurs are 2°2mm. long in the g, only 1°7mm. inthe 2 ,and the comb is more than proportionally reduced, occupying barely a third of the length of the spur, whilst the spines of which it is composed are short and hairlike. In the ¢, the comb occupies fully half the length of the spur and the individual spines look flat and are very unlike ordinary hairs, they are more than twice the length of those in the spur (about o‘'z2mm. and o'rmm.,). The g possesses a scent fan consisting of a rather small wisp of hairs about 3-omm. in length, enclosed in a pocket at the side of the first and second abdominal segments (Chapman). GYNANDROMORPHISM.—The following is the only gynandromor- phous example of which we can find any record: a. Left g,right¢. Incomplete gynandromorph, but more?; right antenna and wings strikingly longer, but not different in cclour and markings; abdomen ¢. Bred. (Germar, J/eck. Archiv. ; Rudolphi, p. 54; Burm., p. 341; Hagen, S. £. Z., xxii., p. 271, Schultz, £02. Woch. fur Eni., 1., p. 351). VARIATION.—The species varies considerably in the depth of the ground colour, in the paleness of the outer marginal area, in the width of the oblique band, and in size. In some specimens the band is deep ochreous, others incline markedly to whitish-ochreous, ab. pad/zda, n. ab., whilst the two projecting teeth on the upper edge of the band vary CELERIO GALLII. 171 greatly in size, the lower, linear, discoidal one being sometimes almost obsolete, whilst the upper wedge-shaped one is sometimes well extended. The band frequently narrows at its base, towards the inner margin, the most remarkable aberration in this direction known to us being one that stops short just beyond the discoidal tooth, the position of its basal portion being occupied by the ground colour. ‘This incomplete- banded form we term ab. zzcompleta, n. ab. In the hindwings also the more or less marked redness of the median area is very noticeable, and whilst, in some instances, the black submarginal band is narrowed to a mere line=ab. s¢ric/a, n. ab., in others it extends outwards to the cilia=ab. /afa,n. ab. The variation in size is very remarkable, and, among our British-bred examples, we have specimens extending from 62°5mm. (the smallest g¢) to 91mm. (the largest 2). ‘Tugwell gives (7. WZ. M., xxv., p. 284) some interesting details as to the size of some of the examples captured wild in 1888. He observes that the measurements of a number of continental C. ga//iz average $s 3ins.—3tins., Qs 3ins—3dins. Of the British-caught examples measured, all the gs and 9s (except 2 g's) are 3ins. to 38ins. in expanse ; on the other hand scarcely any of the many bred gs and ? sreach 3ins., and only 2 2s exceed this measurement, the Liverpool collectors give 28ins. as the average for the bred 2s and 2tins. average for gs; the Deal-bred 2s averaged only 2Zins; the Essex-bred gs averaged 2gins. the 2s 2gins. These figures, Tugwell says, give an average of at least Zins. larger in the caught, over the bred examples, whilst the caught accord in every way with those reared from continental pupz. In answer to the suggestion that bred insects are often undersized, Tugwell states that many of his larva were absolutely fullfed when found. He further states that the largest examples bred from English larve taken in 1888 were as follows: Liverpool—largest ?, 3dins., largest g, 22ins.; Deal—largest 2, 3,,ins., largest g, 2eins.; Essex coast—largest 2 2gins., largest g, 2ins. The imagines caught in 1888 were much larger, St. Margaret’s—the largest ?, 3eims., the smallest, 3fins., the gs 33ins.; Kingsdown—?, 3zins. ; Aberdeen— ? , 3tins.; Plymouth— 9, 3,%ins.; Dartford—@ , 3ins.; Dublin— g, 2;5ins. Tugwell says that these caught examples agree in size with French ones, of which the 9s are 33ins., and gs 3dins. full. Adkin gives further details on this point (Proc. Sth. Lond. Lint. Soc., 1890, p. 75) which much modify Tugwell’s statements and con- . clusions, and he states that the only inference that can be fairly drawn from these figures is that the insects captured in Britain more nearly approach those of known continental origin than do those bred in this country. We have since tested this by measurement and find that pupze, obtained from the German dealers, give measurements varying from 65mm. (J ) to gomm. ( @ ), z.¢., almost exactly the extreme measurements of our own British-bred examples. It is true that the majority of the wild caught immigrants are larger, heavier insects than the British-bred progeny resulting from them, but one suspects that this is entirely due to the artificial conditions of their rearing. As to colour-variation, Tugwell records two examples of an aberration bred in January, 1889, from pupe resulting from larve ob- tained at Deal in September, 1888, in which the usual character- istic dark olive-green markings are replaced by dull grey, and the pale streak that runs from the inner margin to the tip of the 119/92 BRITISH LEPIDOPTERA. wing is obscured and dull in colour; the hindwings dull pale grey, lacking the usual rich rose shade at the anal angle; the body is also grey instead of olive-green (=ab. gvisea, n. ab.). The scales in these examples appeared to be wanting in the ordinary pigment, and the scales themselves suggested immaturity, the larger longer basal ones adhering to the abdomen. Other semidiaphanous examples appeared among the later-bred of Tugwell’s specimens, and these showed still more striking signs of failure in the scale-develop- ment. It is largely on the observations we made on the remarkable appearance of many specimens bred by Tugwell and others, in 1888, that we have founded much of our doubt in accepting strange- looking bred Phryxids with unusual facies, as hybrids (see anfea, pp. 44-54). Mina-Palumbo writes: “ Dr. O. Struve reared from larve obtained at Mondello a form differing from typical ga//z in the lack of the row of spots on the abdomen.” Herz says that the form from the Lena district does not differ from that found in Europe and Amurland, whilst Staudinger makes a similar remark of a 2 found at Saisan. Bartel notes (Pal. Gross-Schmett., \i., pp. 73-74) that ex- amples of C. gall from the Kentei mountains scarcely differ on. the upper side from European specimens, but, beneath, they are distinguished by a darker (blackish instead of dark grey) outer margin of the wings. He also adds that specimens from Labrador, where C. galli is the sole representative of the Sphingids, are smaller than those of Central Europe, and considerably darker in colour; and that they also have an entirely red median band, and narrower, grey-dusted, margin to the hind-wings ; on the underside a blackish marginal band is present on all the wings. He further notes that North American specimens agree almost exactly with the Labrador examples, and says that they are given in the catalogues under the name of C. chamaenerit, but he asserts that they differ too little from Palearctic specimens for one to be able to regard them as a distinct species, and he thinks that the two can only pass for somewhat different forms of one species, brought about by climatic influences. This American form is now known as zatermedia, Kirby, and almost all authors appear to be agreed that the American cxermedia, Kirby (= chamaeneri?, Harris), is merely a race of this species. Oberthur writes (in litt.): ‘I believe that chamaenerii is the same species as gallu. I have the North American form from Canada and Massachusetts.” Kirby considers (Caz. p. 665) the latter to be merely a variety and Staudinger adopts (Cat, p. 102) the same view with the remark ‘‘al. post. magis rubrotinctis.” ‘The insect has been described as follows: a. var. (an sp.) cmtermedia *, Kirby, ‘‘ Faun. Bor.-Amer.,”’ iv., p. 302 (1837) ; Kirby, ‘‘ Cat.,” p. 665 (1892) ; Staud., ‘* Cat.,” 3rd ed., p. 102 (1901). Chamaenerit, Harts, ‘‘Amer.

Expansion of the wings 23ins. Taken in North Americi. This species is inter- mediate between D. euphorbiae and D. galt’, which last it most resembles, but the anterior portion of the mesal stripe of the primary wings is pale rose-colour; the fringe of their inner margin, and of the posterior of the secondaries, is white; there is no series of white dots on the back of the abdomen, and the ventral segments are fringed at the apex with white hairs. This description was taken from an old specimen, apparently somewhat faded (Kirby). CELERIO GALLII, 173 white stripe along each side, which is edged with black on the upper side, along the thorax. The palpi are whitish beneath, and olive-brown above. The abdomen is olive-brown, with a row of small white spots along the middle; the Ist and 3rd segments are marked with black on the sides; the 2nd, 4th and following segments with white, some of them more or less suftused with pink. The underside of the thorax and the legs are of a dull yellowish-brown, and the abdomen is darker- brown, with white lines along the edge of the segments. The forewings are olive- brown, with a buff-coloured band extending from the hinder margin, near the base, to the apex of the wing; the lower edge of this band is slightly sinuous and the upper is irregularly indented; there is a black patch on the base of the wing and another at the end of the cell, and the terminal space and fringes are olive-grey. The hindwings are black, with a rose-red central band, which ends in a white spot on the hinder margin; the outer margin is narrowly edged with dull brown, which is sometimes stained with reddish; fringes white. Larva: The mature larva is from 23ins. to 3ins. long; the head is dull red, with a black stripe across the face ; the upper side of the body is deep olive-green and polished, with a pale yellowish line along the middle of the back, terminating at the base of the caudal horn, and there is a row of pale yellow spots on each side from the 3rd to the 12th segments inclusive ; these spots are placed on a wide blackish band, which crosses the forward part of each segment, and the sides of the body, below the spots, are thickly sprinkled with minute yellowish dots; the caudal horn is long, curved backwards, red, tipped with black, and with the surface rough; the spiracles are oval, yellow, and margined with black. The underside is pale pinkish-green, the true legs black, while the prolegs are pink, with a black spot on the outside of each. Transforma- tions subterranean. FOODPLANTS: This larva feeds on the leaves of grape, Gnothera biennis, Epilobtum angustifolium, LE. coloratum. HABITS: Flies about flowers in the twilight in June and July (Fernald), at wild plum bloom (Caz, fnt., XXxill., p. 99). DISTRIBUTION: Canada, Manitoba, Labrador, United States— New England, &c. (Fernald). We have preferred to give Fernald’s description of this insect, and Kirby’s original description merely as a footnote, as this author states that his description was made from an old and faded example. Eeciayinc.—In confinement, the moth lays its eggs singly, whilst hovering over bedstraw, willowherb, or fuchsia, holding, how- ever, the plant with its legs during the process, but with its wings vibrating all the time; a few seconds suffices for laying an egg, when it is immediately off to another sprig of its foodplant. The egglaying period for a single moth often extends to three or four weeks, the 2 appearing to develop eggs all the time, a total of Beer 10 Aco being reached for a single 9, if properly ited, but if the weather be hot, and the feeding not up to their requirements, they will not lay more than 4o or 50 eggs, and will die within a week. The eggs are laid from early June until about the middle of July, and hatch, under satisfactory conditions, in about a week. The early-laid eggs often result in larve and pupe that develop autumnal imagines (Head, zz J/tt.). Paget obtained eggs at Great Yarmouth, in August, 1834, from which larve hatched in due coumse (277, Mag, i, p. 435). May notes eggs laid in 1870 Pate Mine On Auest Toth (a7, v., p. 201). Jenner had eees laid on August 24th, 1370, at Lewes (2.47.17, vil., p. 213). Williams records that a worn @? laid about a dozen eggs at St. Margaret’s Bay, July, 1888, and that seven hatched before August 8th (L£77t., xxi., p. 230), whilst Austen notes that three eggs laid by a @ on July 29th, 1838, hatched August 8th, at Folkestone (J. c., A220): ; ' Ovum.—Length almost t‘'1mm., width just under rmm.

After hatching the shell is quite glassy and transparent.

Hapirs OF LARVA.—In the first instar the larve are most difficult to locate with the naked eye, even when on only a very small fragment of a spike of flowers of Galzum verum (Bacot). As they get older, they are not so difficult to find, but even then want closely searching for, and one sometimes, when turning over a plant, puts one’s hand on an individual that had not been previously noticed, and they keep close to the foodplant until they are nearly fullfed. Syme notes (Z£.M.M/,, i1., p. 6) that the larger larve generally are to be found in pairs, and that one being discovered a second is generally within a few yards, and he remarks that it appears strange that a larva, so large and so brightly coloured when fullted, should he difficult to see, especially as it feeds quite exposed, yet it is so, more especially on the sandhills than on the shingle at Deal, and they are more easily traced by the frass which catches the eye more readily than the larva itself; the frass should be followed in the direction of its freshness, as the larva rarely moves more than a yard or two until it wanders for pupation. At Deal, on the sandhills, Syme observes that, in 1857, the larvae were mostly found only on plants growing on loose sand without any covering of moss or herbage. In 1888, Tugwell notes ( Young JVat., ix., p. 237) that the larve were found at Deal, not only close to the sea, but also miles inland, by roadsides, as well as upon open ground, even basking on the footways; he states that the young larve were generally to be obtained on luxurious patches of the plant, but when nearly fullgrown they seemed to prefer more open places, where, by exposure, the plants get dwarfed and they can enjoy fully the direct rays of the sun; when quite full- grown they are very fond of extending themselves on the bare and warm sand, in fact, their polished backs get quite hot, a condition which they evidently enjoy. The larve, when not feeding or basking, hide away most effectually, sometimes partly burying themselves, * Some years ago a ¢ caught at sugar at Leipzig deposited 5 black eggs as it was being taken out of the net, the eggs producing pitch-black larvae, which remained very dark all their lives (Bartel ¢este Heyne). This record wants con- firmation ; it is most remarkable if a ¢ did lay black eggs; those that we have described were very typical green Sphingid eggs. CELERIO GALLII. 174 some being discovered almost covered with sand, which, in a few seconds more, would possibly have been quite hidden from view; 200 were taken, a large quantity of Galzum being daily consumed, for the larvz ate ravenously and fed up exceedingly rapidly. Arkle observes (7., Xx1., p. 257) that, in 1888, at Wallasey, the larva were most frequently found where the Galiuwm verum grew thin and short, especially on mounds and rising ground in the hollows between the sandhills, and as near as possible to the sea, that the larve were fond of feeding, exposed in the hottest sunshine, and that the frass was to be looked for among the thin short bedstraw and followed up until the larva was seen. Porritt, too, observes that, at Deal, on August 30th-31st, 1888, larve of all sizes from about #in. to full growth (some of them being big, grand spotted fellows) were mostly found on the poor, short, sparse patches of white and yellow bedstraw, only three or four being found on big patches, and these exposed on the upper stems of the plants at Deal. Buckler notes (Zarvae, &c., ii., p. 37) of some larve that he had between September 6th-26th, 1870, that they fed freely on the flowers, unripe seeds and leaves of Galium verum, and occasionally ate a little fuchsia, but that when large and fullfed they were restless and wandered about for a day or two before they settled down to spin their puparia, which they had all done by October 8th. Bacot says (zz itt.) that the adult larva does not exhibit any tendency to shorten its thoracic and enlarge its front abdominal segments in the manner of the larve of Eumorpha (elpenor) and Theretra (porcelliis), but that, if touched anywhere on the back or sides, it jerks its head fiercely backwards, striking the irritating object with its head or clasping it with its mouth and legs. These movements are made with surprising rapidity and _ vigour, and with quite sufficient violence to detach, if not to stun, any parasitic fly that might attempt to oviposit in it. On the other hand, Buckler’s remarks (Joc. cz.) suggest that there is some resemblance to the Eumorphine habit, for he says that, in form, they reminded him of the Cheerocampids, and that, although the thoracic segments are but slightly retractile, yet they are tapered off rapidly to the head, which is rounded and smaller than the prothorax, the rest of the body being tolerably cylindrical, &c. May observes that the larve almost invariably eat their cast-off skins. The years in which the species has been abundant in Britain have been 1859, 1870 and 1888. ‘The following are some of the records of larve captured. Newman observes that, in 1855, many larve were taken on Galiwm on the coast sandhills, and in gardens on fuchsias. From August zgth to end of September, 1856, about a couple of dozen of larve were found on the Deal sandhills (Syme), whilst Farren records them from August r1th- 24th, 1856, on the Gogmagog Hills, near Cambridge. At the end of September, 1857, larve again began to appear at Deal, and specimens continued to be found until the beginning of November, in 1858 three only could be found, and these in the early part of October, but, in 1859, by the second week of August, the greater portion of an extensive brood had evidently disappeared, and only some 4o or 50 larve were obtained during the remainder of August and the early part of September ; searching in August, 1860, and September, 1861, tailed to produce a larva, but three were taken at the end of August, 1862, and none again in 1863 and 1864 (Syme, Z£. M, MZ, ii., p. 5). 176 BRITISH LEPIDOPTERA. The same observer adds that, from his observation, the larve may appear from the beginning of August to the ena of October, and one can have no certainty in meeting with them even if one be in the right locality unless one is able to make a protracted residence in the spots where the species is expected to occur. In 1859, larve were taken at Ilfracombe on fuchsia (Mathew), at Shoreham on Galium verum (Rickman), at Eastbourne (Costick), at Carlisle (Armstrong), at Kilburn, in a garden, on fuchsia (Wormald), also on August 22nd, on fuchsia, at Bridgewater (Sanders), whilst: Harding records six from Hackney, in a garden, on fuchsia during the first week of August, six more fullfed on Galzum verum on August 12th, on the Deal sandhills, and four others between this date and September roth in the same locality. Six larve also were obtained in Victoria Park, “a day or so before August) 4th, 1850) (2. Ve 77 160). Rogers recorded 36 larvz, from near Dover on Galium verum, between August rst-11th, and at Waliasey, August zoth, 24th, 26th, are given as dates of capture, whilst at Charlton a fuilfed larva was found at the beginning of September (Potter), and Newman states (Zool., p. 6693) that an unusual number of larve had been taken during the autumn on the southeast coast on Ga/zwm, and others on fuchsia in London. In 1870, larve were found much more widely distributed, and Newman says that they were extraordinarily abundant, hundreds of larve being taken. They were reported as occurring freely in the neighbourhood of Gravesend (Button), a larva taken as early as July 29th, 1870, in a garden at Ply- mouth (Bignell), six larvae were found on August 28th, 1870, feeding on Galium verum on the Wallasey coast and several others later (Greasley), whilst Gregson notes that, to his knowledge, two individual coilectors took too, and 80 larve respectively, and others fewer numbers on the same stretch of coast. ‘The larve from which Buckler’s beautiful figures were made (Larvae, &c., pl. xxiv., figs. 1— 1g) were also captured here between September 6th-26th, 1870. A nearly fullfed larva was taken on Durdham Downs on September 5th (Greene), another on September 7th, at Newcastle-on-Tyne, which went down on the rith, whilst a small larva was found on the coast near South Shields about the middle of August (Hamilton), small larve found on September gth on the shores of the Solway Firth were still feeding on October 14th (Robinson), larve taken September 18th, 1870, at Lewes (Jenner), three larve were taken on G. verum on September roth, at Stanley-by-Perth (Marshall), and three larvze were found between Glassmount and Kinghorn Loch in September and a fourth on October 3rd, which was still feeding on the 8th (Syme), &c. There is a record of 18 larve being taken near Brighton in 1871 (Z£. JZ. M, viii., p. 112) by Edwards, but no further details are given. Eedle recorded three larve as being found in 1872, and Lawton records ( Yorks. List Lep., p. 18) a larva at Spurn in 1877. But 1888 was the great C. gall year. The earliest larvae appear to have been taken during the last week of August when Meek captured many examples on the shingle between Kings- down and St. Margaret’s Bay ; and Porritt obtained a dozen larve on August 30th and 31st on Galzum growing on the shingle near Deal and one in St. Margaret’s Bay, whilst, on the same days, Tugwell took 11, making a total of 23; these larve varied much in size, and the CELERIO GALLII. Lal largest went down by September 14th; on September 11th, a search of about two hours on the same ground produced more than a dozen larve some of which were still quite small (Tutt), and Tugwell between August 30th and the end of September took some 200 examples in the Deal district. Many also were captured in other parts of the country—larve common during the last week of August, 1888, on Galium verum, and the following week about a dozen others were taken, on the sandhills near Shoeburyness (Cooper), larva on August 31st, 1888, on the cliffs at Cromer (Tawell), at Shoeburyness, full- fed larve were taken well on into September (Sheldon), Jarve on September roth, 1888, at Reading, feeding on Clarkza in garden, not quite half-grown, were fullfed, however, by September 25th (Barnes) ; some larve were taken at Newmarket in September, 1888, almost in the town (Verrall), between September 4th-1g9th, 1888, on the sandhills at Wallasey, 35 larvz were collected, twenty of which were retained and duly pupated, these pupe kept in a warm kitchen, the first imago appearing October 29th, 1888, 16 others following between then and December gth, when three living pupe were left (Capper), in the latter part of September, seven larve were found at Lytham, and one at St. Anne’s-on-Sea on September 27th, 1888 (Baxter), 22 larve were cap- tured on Lpilobium angustifolium at Risley Moss, near Warrington, Sep- tember 22nd-26th, all the larve being taken in a bed of this plant some 50 yards long (Collins), September 8th-roth, 1888, 21 larve on the Wallasey and Crosby sandhills (Newstead), larve from September 8th- 15th, 1888, taken by the local collectors in very large numbers on the Wallasey sandhills (Arkle), two larvze feeding quite exposed in the bright sunshine on the sandhills at Hartlepool, September 23rd, 1888 (Gardner), over 30 larve were taken in August, 1888, round the coast of Morecambe Bay and Carnforth Marsh (Murray), and others in September, 1888, near Glasgow (Eggleton), two larve on September 13th, 1888, at Ramsgate (Buckmaster). One would possibly be well within the mark if one assumed that 600-1000 larve were ob- tained on the Deal, Essex and Cheshire coasts, of which possibly about one-third produced imagines. Cooper and Tugwell both failed to find a single larva in 1889 in the localities where the species was so abundant in 1888. Gregson’s notice of larve ( Young lVat., x., p. 213) at Wallasey was later corrected, the larve turning out to be those of Sesta stellatarum, whilst the record of its occurrence at ‘Deal (loc. civ, X., P. 231) is very vague and not based on personal observation, so that the evidence available points to the 1888 immigrants having quite failed to establish themselves. On October 13th, 1892, a single black larva was taken at Chiswick (Sich), five larvee were found in the autumn of 1894 on the Essex coast, but although several days were spent in seaching many miles of coast, no more larve were found (Harwood). In 1897, a single larva was taken at Starcross and spun up on August 13th (Benthall), whilst a larva was taken on September 14th at Wallasey, and three others on September 18th, 1897,at Waterloo(Moss). As to the appearance in abundance of the larve in 1888, the following notes are interesting : From imagines taken at St. Margaret’s Bay between July 24th and August 6th, 1888, Williams obtained ova that hatched before August 8th. ‘These larvz are said to have been comparatively small when Porritt and Tugwell obtained at Deal, on August 3o0th-31st, almost fullfed larva, suggesting that M 178 BRITISH LEPIDOPTERA, the moths were on flight and ovipositing some time before Williams and Oswald obtained their specimens (all @s except one). This view is strongly supported by Cooper’s statement (£77, xxi., p. 257) that, at Shoeburyness, during the last week of August, he found the larvze commonly, and that their traces hinted that they had been in great numbers, and that many had already pupated. Meek also records having taken 150 larve at Kingsdown before the end of August, and Greasley had fullfed larve on August 28th, and one would suppose that the bulk of the earliest eggs were laid all over those parts of Britain where the species occurred, by the middle of July. Such evidence as there is goes to support the suggestion that there is occasionally a flight of immigrant imagines into this country in Julyor August, that a comparatively few of these are captured in the ordinary way by collectors, that these immigrants find plenty of suitable spots in which to oviposit, that our summer is suitable to the growth of the early larve, but that our autumn is quite unsuitable both to larve and pupe, that the late autumnal larve are killed off, and that the pupz resulting from the earlier ones are unable to pass through our winter successtully in a state of nature. Want of sun would appear to be the greatest enemy to their con- tinued existence in this country, certainly the mere low temperature of our winter is insufficient to explain their failure to acclimate them- selves, if one considers fairly the winter temperature of some of their permanent localities in the Alps of Central Europe. That pupz go over for many years, and then, as a result of unexplained and unknown causes, produce imagines in great numbers at irregularly recurrent long distances of time, is not worthy of consideration by scientific men, and has no atom of evidence in its support. As bearing on the meteorological difficulties the larva have to meet here, Hele observes that some 150 larve _were obtained by himself and two friends at Aldeburgh in the autumn of 1888, and that, in the early part of October, when there were some frosty mornings, the mortality among them became great. Chappell notes (Young NVat., i1x., p. 238) that he found several dead larve at Blackpool in the autumn of 1888. Tugwell observes ( Young Vat, x., p. 44) that many of the apparently healthy larve that he obtained in 1888 died half-changed, and believes that the early cold of September paralysed them completely ; he suggests that our early cold and wet autumns kill off wild larva. Arkle records (£n¢., xxi., p. 257) some- what similar observations, and states that he came across many dead and dying larvee when searching at Wallasey. No doubt climatic conditions are among the chief factors in preventing this species from obtaining a permanent footing in these islands. As to rearing the larvee in confinement, Newstead notes that 21 were successfully reared in a strong box provided with a strong gauze covering and three parts filled with dry sand. They were supplied twice daily with fresh, “hard” food ; the box was so placed as to catch all the rays of the sun, but was always put under shelter at night and also in wet weather; the larvee seemed to revel in the hot sunshine, but became more or less torpid in wet cold weather and at the approach of night. Larva.—/irst instar (July 17th, rg01): Of medium thickness, evenly cylindrical, with no distinct trace of tapering at either ex- tremity, the anus blunt; lateral ridge well marked on_ thoracic, CELERIO GALLII. 179 poorly marked on abdominal, segments. Head of medium size, almost square in outline, but with rounded corners; colour pale delicate green, spotted or speckled with darker; a few scattered dark tapering hairs with dark bases; the antenne short and stout, the basal joint particularly so. Body delicate whitish-green, showing white at the junction of segments; subsegments fairly marked; scutellum large but not conspicuous, owing to its resemblance in colour to rest of body ; anal plates and plates at base of prolegs much more distinct owing to difference in colour; the caudal horn short, stumpy-looking, markedly distinct owing to its dusky colour contrasting with the tint of the body, conical, with a flattened top bear- ing two hairs (tubercles 1) at summit with hardly a trace of a notch between them (marking it off clearly from such a species as Hyloscus pinastri, with its distinctly forked horn); the horn is roughened, not thorny, but covered with fine pyramidal granulations, and has the appearance of being hard and chitinous, the hairs at summit knobbed ; the setz are very short stumpy black bristles with large black chitinous bases; on scutellum and anal plates the hairs are slightly longer than on the rest of the body, and tapering, on the dorsal and lateral areas of the body they end ina knob; a faintly translucent-looking dark mediodorsal line is present ;_ spiracles small, black-rimmed, those on 7th abdominal larger than those on abdominal segments 1—6, although not so large as those on the 8th; the prothoracic spiracle hardly so large as that on the 7th abdominal; a small white spot beneath the skin on meso- and meta- thorax marks the position of the aborted spiracle. On abdominal seg- ments, tubercle 1i is only very slightly exterior to tubercle i, and there are two subsegments between them ; on the meso- and metathorax they are still distinctly trapezoidal in position, but are situated much closer together on adjoining subsegments; tubercle ili is close above the spiracle on the abdominal segments, but on the meso- and metathorax it is of a double character, and, in some cases, bears two hairs placed very close together ; tubercles iv and v on abdominal segments are both below the spiracle, iv directly beneath on the middle of the central flange, and v very far forward on margin of segment on upper edge of flange ; on the meso- and metathorax only one of these subspiraculars is present (its position suggests that it is v), but there are two similar tubercles (? vi) bearing hairs on ventral margin just above the legs; on the prothorax the prespiracular is a double tubercle ; the skin-surface is smooth without spicules or secondary hairs; the 1st subsegment of abdominal segments is very large, probably com- posed of at least three conjoined, the following 5 subsegments are about equal, but less than half the size of the rst. Second instar (August 2nd, rgo1): The usual Sphingid change at 1st moult, zzz., multiplication of hairs (now of shagreen character), occurs; in form the larva tapers from the 8th abdominal forwards towards head ; the head trapezoidal, with rounded edges, slightly notched at crown; both the shagreen and head hairs are black, short, spike-like, with a small black chitinous base; the skin-surface also thickly dusted with minute, black, ?chitinous specks, fewer in number or absent on the coloured stripes ; caudal horn short and stumpy, of a dark purple colour ; body colours dark dull green dorsally with a paler mediodorsal stripe, subdorsal and infraspiracular bands of whitish or cream colour, 180 BRITISH LEPIDOPTERA. the subdorsal sloping upwards at head and caudal horn (as in Sesza stellatarum), brighter yellow patches on the subdorsal band are now visible, situated on the enlarged 1st subsegment of the meso- and meta- thorax, as well as on abdominal segments 1-8. This enlarged 1st subseg- ment is clearly in some (and probably in all) cases, composed of three subsegments, thus making up the normal number of 8 found in Sphingid larve. The primitive sete are still distinguishable owing to their larger size. Third instar (August 6th, 1901—described with hand-lens only): No.1. The larva somewhat of the shape of that of S. stellatarum ; neat and compact without being either long or stumpy ; the caudal horn small, but well-developed, dark purple (almost black) for the upper four-fifths of its length, covered with numerous thorny- looking hairs. The head more rounded than in last instar and covered with many fine dark bristles or short stout hairs. The scutellar _ plate is conspicuous, being coloured similarly to the head and unlike the body; the subdorsal bands do not reach it, the hairs on it are numerous, and agree with those on the head in colour and in the fact that there are no coloured shagreen-spots at their bases. The spiracles are white, edged with a purple-black chitinous rim, the larger size of those on the prothorax and 7th and 8th abdominals is still noticeable but not so marked as in earlier instars. The subsegments are really 8 (or even g if an obscure fold in the skin at the junction of the segments be counted) in number*; the first three are, however, poorly subdivided and form the large 1st sub- segment, giving really 5 (or 6) small and 1 large subsegment. ‘The shagreen-spots at bases of hairs are conspicuous, but on the enlarged 1st subsegment they have a tendency to weakness, especially on the dorsal area; they are also inconspicuous behind the caudal horn; these basal shagreen-spots are absent on the stripes, doubtless because the stripes were originally developed from the spreading of the coloration at the base of the hairs. There is a broad, well-developed, subdorsal, cream-coloured band which, near the horn, is bordered above by a darker margin; on the subdorsal band are a series of bright yellow spots, which occur where the band crosses the rst (enlarged) subsegment of each segment from the mesothorax to the 8th abdominal, inclusive; these spots are oval rather than round and slightly broader than the band on which they are situated; they are bordered above by a narrow dark line.. There is also a broad, well- marked, infraspiracular band of pale yellow or cream-colour with a tendency to develop a bright yellow spot just beneath each spiracle, the spot surrounds tubercle iv, the only primitive seta that is now distin- guishable (with a handlens) from the shagreen tubercles. ‘The true legs are pale green. The larva just described in 3rd instar is of a pale bright green tint, slightly darker on dorsal area, and with a bright yellow-green dorsal stripe; the head, scutellum and anus being of a paler and more pellucid green. [This is called No. 1 in the following notes. Two other forms are now described in the 3rd instar as Nos. 2 and 3.] No. 2 7m third instar-—The head dark dusky green, dark olive (almost black) at crown and round the mouth- * Each segment of the body, except the thoracic and posterior segments, has a very broad subdivision in front on the back, followed by six narrow ones, though, whilst the larva is very young, the two hinder folds are united into a broader one, the last wrinkle being smoothed out; these wrinkles or folds extend as low as the spiracles (Buchler). CELERIO GALLII. 181 parts and cheeks. The scutellum also dark olive, almost black. The ground-colour of the body dark dusky olive-green, slightly paler on lateral area; a pale green mediodorsal band looks almost white against the dusky skin; the shagreen-spots show up very markedly against the dark sround-colour and also appear almost white by contrast therewith. The true legs, anal plate, and plates at base of prolegs are dark olive-green, almost black. (This is the most conspicuously marked of the three forms of the larva under observation.) No. 3 7 third instar.—| This is a still further pro- gression from the pale green form (No. 1) than is No. z.] Head, scutellum, true legs, plates on prolegs and anus entirely black : the dorsal area without median stripe and shagreen-spots, though faint traces of latter are observable near the subdorsal bands, and a very faint mediodorsal band shows up just before moult. The colour of skin of so dark and dusky an olive tint as to be almost better described as black; the lateral and ventral areas, probably on account of the shagreen-spots being welldeveloped, look paler and greener, although the dark pigment under unspotted portion of skin is possibly not really less intense; the yellow sub- dorsal and infraspiracular bands are unaltered (as is also the case in No. z), but they show up more brilliantly by lovee! Lourth instar: No. 1. Coloration and pattern now the same as those of Nos. 2 and 3 in same stadium. ‘The ground-colour may be of a rather lighter shade of green and less dusky, whilst the bands and medio- dorsal line are a little better marked, but, in all other respects, it is identical; there is a slight orange tint on the yellow spots, but not so well marked as in No. 3. Nos. 2 and 3 in fourth stadium (August 8th, r901). The head, scutellum, and anal plate sooty-black, the body dark sooty-olive, almost black; both show a narrow, rather disconnected mediodorsal line (although completely absent in the last instar in No. 3). The subdorsal and infraspiracular stripes more or less broken into a chain of vivid yellow spots, more marked in the subdorsal than in the infraspiracular band ; the bright yellow oval spots that occurred in the subdorsal band (on ist subsegments) are now much enlarged, roughly oval in shape, and form the conspicuous feature of the larval coloration, the subdorsal band itself forming only a weak line connecting them. In No. 2 the subsegmental. (1st) spots are pure yellow, in No. 3 the central area of each spot is orange-red. The tendency for the infraspiracular band to enlarge into a series of spots beneath the spiracle is still noticeable, but it is not further developed as is the case in the subdorsal series, there being a tendency for the whole of this band to degenerate. ‘The coloured spots at the base of the shagreen-hairs form a very marked feature, existing as somewhat large pale yellow specks, but, although present on both the lateral and dorsal areas, they are absent on the dorsal area of the large 1st subsegment, the head, scutellum, 8th abdominal and anal segments; their presence on parts of the dorsum of larva No. 3 in this instar is noticeable in contrast with their entire absence in the preceding instar on these areas. Spiracles pure white, with a chitinous rim, their size more equal, although those on the 7th and 8th abdominal segments still remain some- what enlarged. The caudal horn better developed than before, thick at base, tapering to a point, thorny, shiny, dark-coloured for the upper three-fourths of its length, but pale at base. Jifth 182 BRITISH LEPIDOPTERA. instar (August 17th, i901): |All three larve are now alike, except that No. 3 has fewer shagreen spots; they are almost entirely wanting in this example on the enlarged (1st) subseg- ments, whilst in the others there is a well-marked fringe of spots bordering the enlarged ist subsegment.| Colour and markings now brilliant and striking ; rather stout, with medium-sized head (small when fullfed) ; body tapering considerably from the 7th abdominal; the anal segment long, but rather small, consisting chiefly of anal prolegs and flap; the caudal horn rather more developed than in last instar, bright coral-red in colour, raised ona low conical mound and curved backwards much as in larva of Sphinx figustri (in one bent backwards almost horizontally), shiny, chitinous, thorny, with twin-like hairs arising from tubercular bases at summit. Head much rounded, but with tendency to trapezoidal shape in frontal outline, partly retractile, appears fairly smooth to naked eye, has in reality a fine granular surface; colour deep salmon-pink; the base of antenna and labrum white, other mouthparts, tips of antenne, and broad band just above mouth black. The skin of the body is shiny black (like hlack satin), the scutellum and anal plates deep brick-red. The legs and prolegs black, the feet red. Neither infra- spiracular nor subdorsal bands present ; the subdorsal spots variable in shape on the different segments, on the meso- and metathorax they are rather small and elongated vertically, on the abdominal segments the spots become Jarger as they go backwards, getting longer, more elongated into oval outline, with the longer axis horizontal until that on the 8th abdominal segment becomes a broad, short, slanting slash at base of caudal horn, their colour pale shiny yellow ; these spots form the characteristic feature of the larva in this stadium. The coloured bases of the shagreen-hairs are large and form distinct yellow spots; they are, however, almost or entirely absent on the area of what was formerly the subdorsal band, and are also wanting on the latter two-thirds of the enlarged ist subsegment (in reality the znd and 3rd subsegments) ; these shagreen-spots become small and fade out on the ventral area. The spiracles large, white, slightly tinged with yellow at edges, the whole surrounded by a black rim. The hairs are minute, black, rather larger on head, front of scutellum and anal plate than elsewhere. The entire absence of the mediodorsal band and the red central shading to the dorsal spots (both marked characters in the preceding stadium) is very noticeable (Bacot). Smooth, elongate, attenuated anteriorly, of a fine olive-green colour, more or less speckled with yellowish-green ; an interrupted dorsal line of dull pink, and, on either side, one of bright green, meeting the dorsal one at the head ; the lower half of the body and abdomen pale yellowish-green ; a series of large pyriform patches of a yellow colour, bordered by black, with a brown-red spot in the middle of each ; these spots lie in the dorsal lines which meet on either side of the dorsal horn; those on the middle segments are the largest and brightest; a Jateral line of yellow, having on the segments a pinkish-red speck, on which are the stigmata; a pale yellow ventral line; legs yeliowish, true legs tipped with dark brown. Head slate-colour, with the mandibles black, labrum green, palpi yellow, tipped with brown, escutcheon fine green, with a slate-coloured oval patch on it; anus with a slate-coloured patch above ; caudal horn brown, tipped and granulated CELERIO GALLII. 183 with black; stigmata light orange, bordered with black (Chaumette, Zool., 1X., p. 3160). Newman describes the larva (£x+., v., p. 192), and Robinson gives some details of the larva in three instars (#.I/_JZ, Vil., p. 187). hee OF LARVA.—We have already detailed (anted, pp. 180- 181) Bacot’s description of three different forms of the larva in the 3rd instar, the individuals not being so unlike each other in the rst and 2nd, nor again in the 4th and sth, instars. Many authors have dealt with the variation, and Buckler gives (Larvae, &c., i, pl. xxiv., figs. 1—1g) some excellent figures of different forms thereof in his possession. He describes (Joc. cct., pp. 37-40) an example (one of six *), sent to him in September, 1870, and which he regards as the type, as follows: ‘This larva, on its arrival, was about three-quarters of an inch in length (in 37d zustar), of a rather bright, full, opaque green, the belly and legs a little paler than the back and sides, with dorsal, subdorsal and subspiracular stripes of pale ochreous- yellow. Upon the subdorsal stripe, on the front of each segment, appeared an indication of an oval spot of a little deeper yellow, with the faintest possible outline above of black; the horn at this time, but slightly curved, semitransparent, and of a reddish tint, tipped with crimson ; the hinder wrinkled portions of the segments dimly showing some whitish-green freckles. On moulting (into 4th instar) it changed into a deeper, brighter, and purer opaque green dress, in which the previous design was now deeper than that of the side, and the belly and legs a little paler still. On the subdorsal stripe, at the beginning of each segment, the oval spots were enlarged and tinged with bright orange, edged above and below with black; the end of the stripe, towards the horn, bore something of an elongate pear-shaped spot. A freckling of pale yellow specks distinctly appeared on the hinder portions of each segment, as well as on the sides ; the spiracles white, outlined with black; the head pale bluish-green, marked with black near the mouth; a pale bluish- green plate on the second segment; hinder extremities pale green, slightly tinged with pink; the horn pinkish-ochreous, tipped with deep crimson. When a length of an inch and a quarter or there- abouts is attained the final moult (into 5// zmstar) takes place, and a great change is at once apparent; the stripes have now totally disap- peared, and the head, the plate on the second segment, and the anal flap and prolegs, show purplish-red. In the individual whose changes I have been tracing, the ground-colour at first was opaque-black, relieved only by the pale yellow subdorsal spots, a few small freckles and the spiracles; but investigation with a lens disclosed an infinity of little puckers and wrinkles, reminding one of the texture of crape. By degrees these wrinkles were smoothed out * Buckler must have obtained more specimens afterwards for it is recorded (Zrans. Ent. Soc. London) that McLachlan exhibited at the meeting of the Ent. Soc. of London, held on November 7th, 1870, no fewer than 16 different forms of the larva figured by Buckler, and all found in 1870. Tugwell writes: ‘‘The larve vary immensely in colour and marking, and not only include the eight forms figured in Buckler’s Larvae, &c., ii., pl. xxiv., but also several others. In some, the usual pale yellow or creamy-white subdorsal spots were replaced by a bright rose-pink colour. Three larve were entirely black, without any markings; and two, halfgrown larvee, had the subdorsal markings much freckled with violet, making them extremely handsome.”’ 184 BRITISH LEPIDOPTERA. as the creature grew, and the final dress was assumed.” He then describes this same larva, when mature, as follows: ‘“ Length, when stretched out, two inches and seven-eighths. ‘The back and sides of deep bronzy olive-green, but below the spiracles and on the ventral surface the colour is a smoky deep purplish-pink ; although the boundary is clearly defined, yet a gleam of the one colour tinges almost imperceptibly the other, both above and below. -There is no subdorsal line, but, im its place, a newer fourteen somewhat roundish spots; four of those on the thoracic segments are small, the others large, the hinder one somewhat pear-shaped, pale golden-yellow in colour, and set in transverse ovals of deep black, which melt into the ground-colour ; the spiracles yellow, outlined with black, and surrounded by a cloud of darker olive than the ground-colour ; a few small yellow specks are sprinkled along the sides. One can well make out a thin dorsal stripe of deep ochreous-olive, wide at the beginning of each segment, looking as if it were show- ing dimly through the surface from a depth below. ‘The head is purplish-pink, the mouth black, with a streak of pale yellow above it, and yellow bases to the papillae, and just above them is a narrow circumferent band cf black. The plate on the second segment, the anal flap, and the prolegs are dark pinkish-red; the anterior legs black, the ventral prolegs purplish-pink, with an outward bar of black near their extremities; the horn is semi-translucent and blood- red; the whole surface of the skin, excepting on the thoracic seg- ments, is now brilliantly polished, and resplendent with the play of light at every movement.” ‘Taking the above as the type, his larve divided into two other main sections as to ground-colour— the pale olive and the black, and each of these (as well also as the dark olive type) furnished a further variation in points of detail. These worked out as follows: I. Neither a light nor a dark olive-green, but between them; the large yellow spots developed into pear shapes, the small end of each projecting forwards as a spot on the segment in advance. 2. Dark reddish-brown, with just a tinge of olive, and with the addition to the usual obscure dim dorsal line of a bright pale ochreous mark at the beginning of each segment, terminating at the end of the broad first subdivision, w hich appears like a black band ; the bright yellow subdorsal spots as before. The ground- colour of the back and sides a pale brownish ochreous-olive ; the subdorsal pale primrose-yellow spots and the spiracles environed with black ; the belly and prolegs rose-pink. 4. A deep jet black on the anterior segments, bluish-black on the others; the head, thoracic plate, and anal extremities of very dark purplish-red ; the subdorsal spots of a dirty and dingy yellowish-drab tint, with their centres more or less filled up with blackish-brown, in one or two instances wholly obliterated. Ground-colour entirely bluish-black, the deepest tinge of purplish-red on the head, the plate behind, and the anal flap, which, with the subdorsal spots, the spiracles, and an extensive irroration of small dots, are all of the purest pale golden- yellow, the black ground being left unbroken as a band across the back from one subdorsal spot to the other. Buckler then states that, in every instance, the skin, after the last moult, was black for a day or two, as previously mentioned ; but, at this time, one may judge of the colour the larva will eventually assume by the tint of the head, thoracic plate, and anal extremities ; these parts, if then quite black, indicate that the ground-colour will be black to the end of its career; but if they are of deep purplish- red, the larva will turn to a dark olive or brown; or should they CELERIO GALLII. 185 be of a bluish-green slightly tinged with pink, a pale olive larva will result. He further notes that, besides the forms described above from living larve, he cbserved amongst some figures lent him by Syme, one of a black variety, with the subdorsal spots of a dull crimson colour. He adds that Syme has had altogether about 200 larve, and says “head always red,” whilst Stainton, in his notes made from living larve, says ‘‘head pale greenish,” with the memorandum that Sepp’s figure came nearest to his specimens. Bartel (following Steinert) writes (Dze Palacark. Gross-Schmett., \., p. 72) as follows: “The larva varies much. Among the young larvae 3 principal forms are distinguishable: (1) A dark green form, with light dorsal, subdorsal, and spiracular lines, otherwise without markings. (2) Blue- black, with connected sulphur-yellow spots. (3) The third form is green, with the usual yellowish stripes, of which the middle one is, on each segment, a little mixed with orange- colour or red. The /ul/-grown larva is 80mm.—gomm. in length, and is subject to very manifold variations. ‘The colouring is mostly piece. (1) Green-yellow. (2) Dark green. (3) Blue-black. On this ground-colour there are either yellow or rose-coloured spots, which are commonly granulated with black. The larva is mostly lighter or darker green, with a yellowish lateral stripe and a whitish mediodorsal. On each segment stands a dark yellow light-margined spot. The horn is red, with the tip black. Spiracles yellowish, broadly bordered with black. Belly reddish-grey, head and thoracic legs blue-grey. Another common form is_ blackish olive-green, with yellow dorsal stripe, which, however, may often be wanting, and large, round, light or dark yellow spots, margined with black. The body is densely covered with black dots, and, beside the legs, is coloured dirty red or reddish-yellow. Not rarely also a glossy black-grey form of the larva is to be met with, which is densely covered on the sides with black dots. The dark forms of the larve have been incorrectly pointed out as stung. Newman, in describing the larva (£z¢., v., pp. 191-192), notes, among other interesting details, that the caudal horn differs in length in different specimens ; in some it is very short and stumpy, while in others it forms a regular and rather elegant curve, and every intermediate gradation of form occurs, whilst the colour of the larvz also is variable. He states that three specimens under examination have the ground-colour dull black, but the ground- colour is in some so light as to approach pale wainscot-brown. These three specimens also vary in other respects : I. Has a red head and horn; a narrow mediodorsal stripe of pale canary- yellow ; a lateral series of 10 rose-coloured spots on each side, 9 of which are nearly circular, and the 10th somewhat pear-shaped, the smaller extremity extending to the base of the caudal horn, and a narrow lateral stripe in the region of the spiracles almost white. The rose-coloured spots are connected by a series of smaller yellow spots, five of which intervene between each two of the former, thus forming a continuous series of spots, which commences on the 3rd segment and terminates at the base of the coral-red caudal horn. After moulting the dorsal stripe disappeared, _ 2. Hasareddish head and horn, no stripe on the back or sides, but a con- spicuous series of 10 yellow spots on each side. 3. Has a black head and horn; no trace of the dorsal or lateral stripes or of the circular paler spots. The three examples agree in having numerous white dots in the 186 BRITISH LEPIDOPTERA. neighbourhood of the spiracles, which are very light coloured; the 2nd segment (prothorax) has something like a dorsal plate, which is pitchy-red ; the ventral flap and claspers are of the same colour ; they all have a yellowish-white labrum, and the base of the antennal papillz is of the same colour. Collins notes some larve taken by him near Warrington, as black when captured, but says that they assumed a greenish hue, the black round the pale spots retaining its colour and giving the spots the appearance of having a black ring round them ( Young lVat., ix., p. 204). Syme asserts that, when fullfed, the male larve are paler than female larvae, and that isolation of a number of the paler larve resulted in male moths being produced therefrom. DEVELOPMENT OF LARVAL MARKINGS.—Bacot’s account (supra) is the first detailed description of the larval ontogeny that has been pub- lished. From this we learn that the appearance of the larva varies at each instar as follows: /zrst instar: Pale green, with dark mediodorsal line. Second instar: Dark dull green, a paler mediodorsal stripe, subdorsal and infraspiracular whitish bands, with brighter yellow patches on subdorsal, the precursors of the characteristic yellow spots that appear later. Z/zrd instar: Variable in colour, a pale medio- dorsal stripe, a strongly marked creamy subdorsal band with bright yellow oval spots on the enlarged 1st subsegments of each segment, also an infraspiracular line with a tendency to develop a bright yellow spot beneath each spiracle. Fourth instar: More uniform again, a narrow disconnected mediodorsal line, subdorsal line broken into a chain of yellow spots with orange-red centres; the infraspiracular band also broken. /2/th instar: Subdorsal, mediodorsal, and infraspiracular lines absent; the subdorsal line of spots strongly developed but without orange-red centres. Syme observes (/.4AZ.J/, i1., p. 7) that, when young, the larva of Celerto gallitis exceedingly like that of Sesza stella/arum, of the same size, being pale or dark green, with a white lateral stripe, but the caudal horn is not blue at the apex as in that species. ~The yellow spots, he says, sometimes do not appear till the last moult, but generally become apparent at the second ecdysis. May observes (£/om., v. pp. 201-202) that larve of a dull pale green colour emerged from eggs August 16th, 1870. S7rs¢ moult occurred August 23rd, the larve then becoming brighter green ; dorsal, subdorsal, and spiracular lines slightly indicated, being of a lighter colour; dorsal area darker green; horn blackish. Second moult occurred August 29th, the larve now grass-green, the dorsal area darker; a narrow yellowish-green dorsal line; subdorsal and spiracular lines pale yellow, edged with black on the upper sides; ten oval yellow spots, one on each segment, in the subdorsal line, between which and the legs the surface is profusely sprinkled with minute light-coloured specks. TZhzrd moult took place on Sep- tember 3rd; many specimens of a deep sea-green, some lighter and some darker; the dorsal area always darkest; dorsal line green- ish-yellow ; subdorsal and spiracular lines yellow ; the ten oval spots larger and of an orange colour; spiracles white; horn black, with the base dirty yellow; head grass-green; edge of mouth black; prolegs black; some specimens entirely black with the before- mentioned coloured markings; all have the whole surface sprinkled with more distinct minute pale-coloured specks, most numerous between the subdorsal line and legs. /ourth moult took place Septem- CELERIO GALLII. 187 ber 12th (Of the appearance in this, the 5th instar, May gives no account). The markings of the larva of this species appear to be developed in a precisely similar manner to those of Zhaumas vespertilio (vide, Weismann, Studies in Theory of Descent, pp. 210-211). He says that the adult larva, as in that species, shows no trace of a subdorsal line. A row of large black spots, each having an irregular, round, yellowish-white nucleus is situated on an _ olive - green, blackish-brown, brown, or dirty yellow ground. A figure of a larva by Hubner is z2'5cm. long, of a light green colour, with five longitud- inal lines—cne dorsal, two subdorsal, and two spiracular lines. The subdorsal is white, and bears, in the place of the ring-spots, small red dots, whilst the line itself is bordered with black where the red spots are situated. Hubner’s figure is possibly of the 37d stage, so that it is probable that, in the second stage, there is a subdorsal line either quite free from spots, or only showing such feeble rudi- ments* as areto be seen in the 2nd larval stage of 7. vespertilio. Of two larve in the 4/h sfage, found in the Upper Engadine, one (fig. 45) was 33cm. long, already of a dark, blackish-green ground- colour, with a broad greenish-white subdorsal line sharply defined throughout its entire length, and containing ring-spots of a sulphur- yellow, with an orange-red nucleus; the black ‘ ground-area” did not encroach upon the subdorsal line, but was confined to two faint crescents situated above and below the “mirror.” Only the two foremost ‘‘mirrors”’ (on the znd and 3rd segments) were without nuclei. The remaining peculiarities of coloration are shown in the figure. The shagreening is present on the sides and a portion of the under surface. A second example was 2‘8cm. long, essentially similar to the former, but was pitchy-black, with a very indistinct subdorsal line and a few ring-spots, the ‘* mirrors”’ of which were also sulphur-yellow, with an orange-red nucleus. The shagreening was quite as strong as in the first specimen, the dots being yeilow instead of white. It is specially to be observed, because of its important theoretical bearing, that, in this larva, the ring-spots were absent on the front three segments, and on the fourth only a faint indication of one could be perceived. In the larva figured, the ring-spots increase also in distinctness from the tail to the head. 5/A stage: The two specimens just mentioned, after moulting, acquired the well-known markings of the adult larva, already briefly described above. The 5th is the last stage. The larva is known to occur in several varieties, Rosel having figured © it in three forms—light green, olive-green and dirty yellow. Having had an opportunity of observing 25 adult specimens at one time, I am able to state that it is not in this instance di- or polymorphismf, but a case presenting a great deal of variability, with which we have to deal. There are not several sharply-defined types of coloration, but the extremes are connected by numerous intermediate forms ; the extreme forms, however, certainly preponderate : Among the 25 larve, all gradations of colour, from pitchy- black to light clay-yellow, occurred, and even to an almost whitish- * This is so. See summary (supra p. 186), where it is stated that the indications of the spots only are to be found in the 2nd instar. t+ Weismann appears here to use the term polymorphism in a restricted sense, and to exclude those cases where many marked types are joined by intermediate forms. 188 BRITISH LEPIDOPTERA. yellow; some were brownish-black, others of a beautiful chestnut - brown, others yellowish- brown, dark clay-yellow or brownish- red. Of 21 specimens, of which the ground-colours were noted, 9 were black, 9 clay-yellow and 3 brown, whilst each of the three again showed various minor modifications of colour. The other colours also varied somewhat. ‘Thus, the ‘‘ mirrors” were sometimes white, sometimes strong yellow, and, occasionally, they also contained a reddish nucleus. The variation in the shagreening was especially interesting, inasmuch as these appeared to have a striking connection with the general colouring of the larva. Black specimens seldom show such sparse shagreening as that represented in pl. v., fig. 46, but are generally thickly scattered with large shagreen-dots night up to the dorsal line (pl. vi., fig. 47), these strikingly resembling the adult larva of Hyles euphorbiae*. The light ochreous-yellow individuals, on the other hand, were sometimes entirely without shagreening (pl. vi., fig. 48), being smooth and much resembling the light ochreous- yellow ot yellowish-red larva of A. nécaea (pl. vi., fig. 51). I have never seen a larva of C. galliz which showed traces of the subdorsal line in the last stage}, nor have I ever met one which possessed a second row of ‘‘mirror”’ spots, so that retrogression or a sudden advance in development does not appear to occur. The adult larva of H. mauretanica, which likewise belongs to the gal/zz group, is very similar to that of H. ewphorbiae, but differs in the absence of the second row of ring-spots. For this reason it must be regarded as a retarded form at an older stage of phyletic development (Weismann, S/udies in the Theory of Descent, pp. 213-215). Cocoon.—The larve make for their puparium a rather coarse network of threads, which binds the sand beneath them with the Galium above into a slight cocoon; those I had, had all retired by October 8th (Buckler) ; the larve spun up on the surface of the sand on which the food was placed (Benthall) ; cocoons slight and spun on the surface of the earth of the breeding-cage (Barnes) ; three or four larvee (in confinement) pupated in the sand about an inch below the surface, the remainder spun slight cocoons on the surface, mixing with them portions of the food-plant, &c., and therein pupated (Newstead) ; the larvee spin the leaves of the foodplant together, just under the sur- face of the ground (Foster). Tugwell notes that several larve that he had in 1888 spun up just on the surface of the ground, but that the greater number had simply formed a loose cocoon amongst the stems of the foodplant, whilst six pupated from one to two inches beneath the soil, and had formed fairly compact cocoons of sik and grains of sand. Pupa.—After a somewhat prolonged examination of the pupa in comparison with that of Hyles euphorbiae, I find them to be extremely alike, and that they differ only by one or two very trifling details. {Whether a larger number of specimens than have been examined would show these differences to be merely varietal and not specific, or whether some more definite point of distinction would appear I cannot, of course, say.] The sculpturing of the surface of both consists of numbers of pits on the abdominal segments, these are alike in both, in size and depth, and in a tendancy to lose their posterior lips, and of the anterior lips to run together into a line of arches, * See also Buckler’s Larvae, &c., pl. xxiv., figs. 1c and 1f. In fact, the whole of Buckler’s figures on pl. xxiv illustrate this point excellently, + Buckler’s pl. xxiv., fig. Ic, gives some traces of this line, CELERIO GALLII. 189 The peculiar character of the sculpturing in front of the spiracle of abdominal segment 5 is usually repeated in C. ga//ii in 6 and even m 7. In C. gall there is often a definite little spine at the mandibular angle of cheek, and the anal spine is rough almost to the tip. C. galliz also has usually some antero-posterior flattening. It may be a smoother, but is often a rougher, pupa than that of HI. euphorbiae. All these characters vary very much so that a mixture of pupz is difficult to separate again. The only one, so far as my observation goes, that can be relied on, is the presence in C. gall of the same prespiracular sculpturing on abdominal seg- ment 6,as on 5. The colouring varies similarly, but the pupa of C. gallit has a ruddy tint, rarely seen in that of H. euphorbiae (Chapman). Length 1Zin., including the short, curved horn or anal spike, and moderately stout ; the head rounded and narrower than the thorax, the anal extremity a little tapered, but otherwise tolerably uniform in bulk ; the wing-cases were close to the body, and extended as far as the fourth abdominal segment; the last five segments were rather deeply cut and flexible, the sides of the incisions smooth, all the other surface granulous. Ground colour deep red, much suffused or sprinkled with black, especially on the wing-, antenna- and _ trunk- cases, also on the back of the thorax; this last had, however, a dorsal line, and the pieces of the thorax were outlined with the ground colour; the antenna-cases and the ends of the wing-cases were relieved by a fine marginal streak of flesh-colour ; the smooth sides of the abdominal incisions were deep and rather purplish-red ; the spiracles blackish-brown (Buckler, October 12th, 1870). FoOoDPLANTS.—Galium verum flowers, unripe seeds and leaves (Buckler), Galzum mollugo (Schmidt), Galzum saxatile, prefers scrubby plants (larve refused Galium palustre and G. aparine, and some Scotch larve refused G. mollugo) (Syme), Fuchsia (Sich), Clarkia (Barnes), Rubia tinctorum, Epilobium palustre, E. hirsutum (Berce), Lpilobium angustifolium (Collins), Galzum sylvaticum, Epilobium palustre, Impatiens noli-me-tangere, Asperula, Tithymalus, Escallonia (Bartel), Vites vinifera (Chaumette). Bartel says: “Lives on LE pilobium angustifolium in Labrador ; the larve living on 7Z7thymalus are mostly olive-green.” Constant, Peyerimhoff and Macker also note C. gall larve as feeding on Euphorbia (= Tithymalus). ParRasiTES.—Tvogus exaltatorius, Panz. (Bloomfield), Amblyteles proteus, Christ(Bloomfield). In the Lena district thelarve were inabund ~ ance but mostly stung (Herz). ‘Tugwell notes that not one of the many larve he obtained in 1888 was attacked by any parasite. In Zool., p. 6031, is an account of the destruction of ichneumon eggs on a larva, taken October, 1857, at Deal. The eggs were whitish in colour, attached to the skin, were destroyed by means of a darning-needle, when the larva pupated in due course and produced an imago in mid-January, 1858, after being forced from mid-December (Syme). Hasits.—The species owes its position in the British list to immigration. For many years no example will be taken, and then a sudden influx of imagines in July or August is followed by a great abundance of larve in August and September. ‘This periodical appearance is common to the more northern and western limits of its range. Thus, we find the species reported as very common at Prague in 1789 (Preyssler), as very abundant in 1856 190 BRITISH LEPIDOPTERA. at Nantes; Graeser notes the larve as very abundant at Behrenfeld in 1870; usually rare in Thuringia, but in some years the larve are abundant; in 1875 the larve were in thousands in the Dresden district ; usually rare at Leipzig, but found everywhere in great numbers in 1888, also generally rare in Crefeld, but common in 1888 ; at Waldeck, uncertain, generally rare, in some years more abundant, particularly so in 1888, in which year, indeed, the species was recorded as being in unusual numbers throughout the whole of Central Europe ; found at Kempten in 1894, although not noticed for 20 years previously ; in the “forties” it was commonesu New Pomerania and the Anclam districts, but has been found only most sparingly ever since. The years of abundance in Britain have been 1859, 1870, 1888, and, in these years, it was also abundant in most parts of Europe in the same latitude as the British Isles. Grentzenberg notes larve as very abundant one year at Dantzig, Moeschler that in Upper Lusatia in some years it is not rare ; Schmid that the larve are sometimes abundant at Ratisbon, Weiler that it is uncertain at Innsbruck, in some years common, Hering in some years common in Pomerania, Heinemann not rare in certain years in Brunswick, and Glitz that it is common in Hanover in certain years. It is difficult to account for this irregularity in the appearance of the species. Fairly abundant almost every year in certain warmer parts of the Alpine region of Europe, the species, without having been noticed to increase to any great extent in its usual haunts, appears, in the imaginal state and at irregular periods, to make inroads into territory from which it has been for many years absent, and strangely, as our “Times of Appearance” show, in different months of the year. The immigrating imagines lay eggs, larvae are found in abundance and pupez_ produced, but, owing to causes, probably climatic, of which we have little knowledge, the pupz fail to develop their imagines, and the following year few or no imagines occur. The moth flies usually in the early evening, and is to be found at dusk at a variety of flowers. Bartel says that, in Germany, the imagines are attracted by those flowers which are especially loved by the Sphingids, more particu- larly Petunia and Convolvulus arvensis, whilst, in Roumania, Petunza and Convolvulus tricolor are given as the favourites by Caradja. Newly-arrived immigrants in this country have been taken at verbenas at Brighton (Griffith), and at the flowers of the same plant at Worthing (Wyatt), at Breadsall (Stowell), at Plympton (Purdue), and at Clevedon (Brackenridge); at jessamine at dusk, at Holloway (Stoneman) ; at honeysuckle, at Great Yarmouth (Paget), at 8.40 p.m., at Breadsall (Stowell), also at Warrington (Greening), at Oundle (Whall), at Wisbech (Glenny), at Anne’s-on-Sea (Baxter), at Macclesfield (Goodall), at Darenth (Mercer), and at Halesowen, near Birmingham (Enock) ; at sweetwilliam flowers at Alford (Garfit), also at Carlisle (Goodfellow), and at Hayton, at 9.30 p.m. (Routledge) ; at petunias, at 6.30 p.m., in Gloucester (Hallett- Todd), also at Hopwood, near Birmingham (Landon), at Brighton (Taylor), at Beccles (Farr), at Leominster (Hutchinson), at Caerwood, (Sellon), at Weston-super-Mare (Aldridge), and at Alphington (D’Orville) ; at rhododendrons at Rugeley (Bonney), at LZchium vulgare at St. Margaret’s Bay (Williams), at larkspur at Dartford (Youens), at white campion at St. Anne’s-on-Sea (Baxter); at scarlet CELERIO GALLII. 191 geranium at St. Weonard’s (Bond), at Buckhurst Hill (Tudor), and at Branscote (Watkins) ; at phlox at Stonehouse (Nash), at red valerian about 9.15 p.m., at Leckhampton (Trye), at carnations at Hackney (Wright), and over Delphinium formosum at 9.15 p.m. at Harrogate (Thompson). Mitchell notes the capture at Wol- amen Of a “2 at 7.20 p.m., a gf at 3 p.m., a 2 ‘also at 8 p.m., and another 2 at 10.30 p.m., while flying over a flower- bed, consisting of phlox, geranium, Dveanthus, asters, Lilium and petunias. In 1843, at Sudbury, a specimen is recorded as having been caught by the tongue by a flower of Ginothera spinosa. Bang- Haas notes that it sometimes flies by day in Denmark in such years as it occurs there. Leech records it as hovering over flowers by the side of a mountain in the neighbourhood of Tsuruga, and, in Belgium, Lambillion says that it flies on sunny days over flowers like Sesta stellatarum, and Mengelbir notes the imago as revelling in the bright sunshine at St. Moritz. Doubleday captured one in the early morning, at Epping, hovering over flowers of Avgemone grandifiora ; and it was also noticed, at Oxton, flying at geraniums in the daytime (Studd), flying in the hot sunshine at Deal (Harding), flying in the hot sunshine about 2 p.m., and hovering round a woodland pool at Riving- ton, near Bolton (Calderbank), whilst a fine specimen was seen at 1 p.m. over petunias at Cambridge (Cumming), and another hovering over rest-harrow at 11 a.m., in bright sunshine, at St. Anne’s-on-Sea (Baxter). This species is not very frequently recorded at light. ‘Tetley, however, notes that imagines occurred at Taunton, in 1888, in some numbers, at electric light, nearly all being much damaged as they had got inside the large globes of the lamps; Farrant captured four thus (Ent., xxill., p. 100). Bloomfield heard of one taken at electric light at Hastings, in 1892; Burrows took one on a lamp at Snaresbrook station; Sheldon had one fly into his room at Kingsdown in 1888, as did Stainton at Lewisham, whilst Murray records one as flying into a forge at Lancaster. Examples have also been recorded as resting on an ash trunk in the Hawick district (Guthrie), on an apple-tree at Witham (Cansdale), on a poplar at Plymouth (Rowe), on a creeper at Birmingham (Landon), on the quay, at Hartlepool (Gardner), and in a- greenhouse at Plumstead (Barns). The female moths, as we have already noted, live for a long time in confinement, three to four weeks if well fed, and they continue to develop eggs all the time, laying from 300— 400 apiece, but if they are badly fed, or the weather is very hot, they lay from 40—50 eggs and die in about a week (Head). ForcING pupé.—In confinement very few British-reared pupz go over the winter satisfactorily, and produce their imagines the following summer, as is usual with Continental-reared examples. The following have been recorded—July 6th, 1856, another a few days later, and a third August 6th, 1856, from larve obtained August, 1855, at Deal; another bred July, 1860, from larva found August, 1859, at Deal (Harding); May 25th, 1857, from larva found September, 1856, at Brighton (Griffiths), five bred in 1860 from larve found in 1859, near Perth (White), four bred in 1860 from larvee obtained in the autumn of 1859, at Cockermouth (Robinson), July 8th, 1860, from larva obtained August 16th, 1859, at Rottingdean 192 BRITISH LEPIDOPTERA. (Image), July 9th, 1860, from larva found at Lytham in the autumn of 1859 (Gregson); August rst, 1860, from a pupa obtained from larve taken August 16th-2z9th, 1859, another pupa being then alive (Batho); July 18th, 1862, from larva found September ath, 1861, at South Shields (Eales), July 17th, 1871, from larve found September 18th, 1870, at Lewes (Jenner), two imagines in June, 1889, from larve taken at Ramsgate in September, 1888 (Buckmaster). Bloomfield notes (2.47. M7, xxv., p. 455) that Hele of Aldburgh had 20 pupe from 1888 larve, that these were kept in sand covered with moss in a cool room, and with no forcing whatever, and that of these, 13 ima- gines emerged in June and July, 1889. Peek, of Swefling, had 14 pupz kept in an aquarium on their original sand from the seashore covered with moss, and the only forcing was a tepid bath once a fortnight, or when they looked dry. These 14 pupe produced ro inoths in the following June and July, two other pupz being ichneumoned. Generally, however, the want of success by those who attempt to keep their pupz over the winter is so marked that most lepidopterists prefer to force them, subjecting the pupz, after they have rested. normally for 2 or 3 months, to such conditions of moisture and atmosphere that they are tempted to emerge prematurely during the winter months, although itis remarkable that some pupa resist this forcing treatment, whilst others respond most readily. Syme obtained imagines March 2th and 23rd, 1857, from 1856 pup, the latter being kept on damp moss exposed, from January 26th, to an average day temperature of 75° F. by placing in fender every day. Costick reared imagines January, 1860, from larve found in the autumn of 1859 at Eastbourne. Buckler was the first to record the rearing of forced examples irom the 1870 larve: | He began the forcing: processmronme pupe a few days after Christmas, the first moth emerged January 18th, the second on the roth, the third on the 22nd and the fourth on February gth, 1871 ; Capper also reared more thana dozen from New Brighton larve, the earliest emerging February 8th, 1871, the others somewhat later. From 1888 larvae, Elisha bred several imagines in March, 1889, the pupz being forced at a temperature of 60° F.-70° F., the specimens emerging from 14 to 16 days after being placed in this heat and no pupe lying over ; Corbett forced his pupz, obtained from larve September, 1888, the imagines emerging in November and December of the same year; Arkle forced 12 pupe from larve found on the Cheshire sandhills from January 1st, 1889, and bred five imagines between February roth and March 26th, the other pupze dying. Newstead states that larve, found on the Wallasey sandhills from September 8th-1oth, 1888, pupated from 15th- 22nd, 17 pupz being obtained, the pupz were kept in a room ata temperature of 45° F. to 50° F., and remained there until January 1st, 1889, when they were removed to a temperature of from 50° F. to 55° F., and were slightly sprinkled with water for the first time ; on the 23rd four pup# were placed in a ‘ Pine: stove™ ma temperature of 60° F. to 75° F. ; on February 26th one imago emerged, the three other pupz also disclosing imagines before March 2nd. The remaining pupz were then placed in the “ Pine stove” and similarly treated ; the first imago emerged on March 26th, the last on March 31st; one pupa, however, resisted the forcing, lived on for some weeks, and was then placed in “spirit” to be preserved as CELERIO GALLII, 193 a specimen. The conditions under which they were reared are summarised as follows: September 1&th-October 21st.—WLarve. Out- side all day, fully exposed to sun, but always taken in during rain and at night. Movember and December.—Pupe. Indoors; day temperature 50° F., might 45° F. Sanuary srst+22nd.—Day tem- perature 55° F., night 46° F. Once damped. ‘Fanuary 23rd to time of emergence.—Day temperature 75° F., night 60° F. Kept constantly damped. Tugwell was probably the most successful collector of the species in 1888. He forced all his pupa, and records ( Young Vat. x., p. 44) rearing 53 specimens between December gth, 1888, and January 22nd, 1889, later emergences bring- ing thetotalup to1ir (oc. cit., p. 145). His pupz were exposed to an average temperature of 70° F., and were mostly out by April, when some, still remaining in the pupal stage at that date, were placed in a cool greenhouse, but from every living pupa an imago had emerged by July. He observes that it is really remarkable that, whilst the greater number of pupz responded readily to the forcing treatment, others should resist it and emerge at the normal time of un- forced specimens. In 1897, Benthall bred an imago on Decem- ber 8th, 1897, from a larva obtained at Starcross on August 7th, 1897. Moss notes that, of four larve from the Wallasey and Waterloo coast, September 14th and 18th, 1897, one larva was preserved, the pupz from the other three were forced from October 2oth; from one of these, an imago, emerged on November 15th, one died on November 30th, and the last emerged December 1 9th, 1897. Hapirat.—In Britain, where the species is very uncertain in its appearance, sometimes not being seen for many years, and then occurring in hundreds in the larval stage in certain favoured localities, one finds that it prefers wind-swept sandhills to any other locality, and that those nearest the sea-coast in Kent, Essex, Cheshire, Devon, Durham, &c., are the most frequently chosen, although Cambridge is also a well-known locality. At Deal, one of these favoured spots, it not only frequents the sandhills, but the larve are to be found abundantly on every little patch of Galzuwm growing on the shingle between Deal and Dover, and within reach of the sea spray. These localities are very similar to those of the more northern continental dis- tricts favoured by occasional visits from immigrants from more southern climes, ¢.g., Snellen notes larva as abundant some years on Gadlium on the dunes of Holland; Paux states that the insect is accidental in the dept. du Nord, the larve being found (as with us) in August and September, at intervals of some years, yet always in the same localities, ¢.g., the low “roads” of Wattignies and the dunes of Dunkirk, and the same is true in Belgium, although, in New Pomerania, where it is also sporadic in its appearance, it is said not to be specially partial to the coast. Syme observes (Z.47.M,, ii., p. 6) that the insect is not only irregular, but very local—capricious, one would be apt to say. He states that, although search has been made for the larve all over the sandhills from Deal to Sand- wich, he has never found it, except from the 1st battery southwards as far as the large sandhills extend, and from the sea westwards for 200 or 300 yards; in 1857, and in this year only, the larve were taken on the shingle from Kingsdown to the vicinity of the rifle-butts to the south of that village, a little more than three- N 194 BRITISH LEPIDOPTERA. quarters of a mile. Tugwell notes that, in 1888, he found larve over a considerable area in the Deal district, and not at all confined to the sandhills and coast, but extending from St. Margaret’s Bay on the southwest to Pegwell Bay on the north, and extending from the sea-line to places five or six miles inland. In Essex, Cole found larve on the higher land bordering the shore of Osey Island, in the Blackwater estuary. Bartel says that, in Germany, the larve prefer sunny slopes and openings in woods, although, on the continent, its permanent home seems to be along the lower moun- tains of the central Alpine chains and the various branches origin- ating therein, ¢.g., Schutze notes the species as rare in the plains of Saxon Upper Lusatia, but common in the mountains, Bruand observes that, in the dept. Doubs, the species is more abundant in the mountains than in the lower districts, whilst Alphéraky states that it occurs in the mountains of the Kouldja district from 3000ft.—goooft. In France, Oberthur says the species is more or less eastern, becoming commoner in Germany, whilst Peyerimhoff notes it in Alsace as preferring warm sheltered spots in the high mountains. It appears to be almost absent from the Mediterranean district, the only record that we have, besides those from Sicily and southern Italy, being the capture of a fullgrown larva at Trieste on September, 6th, 1897, by Mathew. SUMMARISED HISTORY OF THE SPECIES AS BRITISH.—Harris is said, by Stephens, Curtis and others, to have first noticed this species as British in the Awre/zan in 1778, under the name of exuphorbiae, a larva having been found by him at Barnscray, near Crayford, on marshy ground, about the middle of August, but his description of the larva, which died soon after capture, and was not the one he figured, certainly suggests none of the characteristics of either euphorbiae or gallit, and one suspects that it was neither. Donovan is also said by Dale and others to record it as British, under the name of euphorbiae, in the Wat. Hist. of Brit. Insects, i1., pp. 51-52, published in 1794, from an imago taken at Bath, and four larve taken in Devon- shire by Curtis, but as Donovan says that the Bath specimen was in his own collection, and he figures ewphorbzae excellently, in all its stages, from French examples, it is unreasonable to suppose that the Bath insect was anything but what Donovan says it was, and the larve are certainly as likely to have been euphorbiae as gallu. Ylaworth says (Zrans. Ent. Soc. Lond., 1807, p. 9o)mumae he had a British specimen wnich he had mistaken for ewphordbiae, until Montague informed him in a letter to his friend, the Rev. W. Vaughan, that ‘he had taken the larve of both gad/zz and euphorbiae in Devonshire and bred them.” This specimen he figures (pl. iv) under the name of gaé/77, but it is an undoubted ezphorbzae, with, how- ever, certain abdominal spots resembling those of Phryxus lévornica. Stephens observes (J//ustrations, &c.) that he ‘saw a living speci- men about 1816, which was taken in the beginning of June on some palings in the City Road, and a second was detected near the same spot a year or two back.” Healso refers to the larva Harris took, and adds that ‘‘the species has several times occurred in the West of England, and has been taken near Penzance, in Cornwall, and at Kingsbridge, Devon, by Dr. Leach.” He figures (pl. xii., fig. 2) the true C. gall very well, and gives a good description thereof, ap- CELERIO GALLII. 195 parently the first reliable figure published in Britain. Dale notes ( Young Nat. supp. p. 58) that ‘“Tuther obtained a specimen in _London on June 27th, 1812, which is still in the ‘ Dale’ collection, Cole took one at Islington in 1825, and Garnons one at Colchester in 1830; whilst Lockey found one at Charmouth in 1831, and two were taken on August 6th at Norwich;” Doubleday also captured an example very early one morning in August, 1831, at Epping em. Mae... p. 285). Lhe year 1834 1s the first gall year of which we have any record ; four imagines were taken in August (2nd, 9th and 2oth), and five or six others seen at Great Yarmouth, whilst several larve were found later on Gadzum verum on the North and South denes (Paget, Lut. Mag., ii, pp. 434-435); Bass also records an example as captured in mid-September, 1834 (Joc. cit., il.. p. 529), and Dale states ( Young /Vat., supp. p. 58) that “ three others were recorded from Milton, near Peterborough, and one at Longhurst, Somerset. In July, 1835, an example was taken at Coundon (Bree, Ann. Mag. Nat. HAiist., 1x., p. 482), also one in the same month at Worcester, whilst a third was captured in the Isle of Wight, by Lees (Edmonds, Z¢. A/ag., ili1., p. 410); two more were taken in early September, 1835, at Cumwheaton, near Carlisle, by Heysham (Joc. ci¢., p. 409). No further record appears until September 15th, 1842, when a fine ¢ was captured at Whitefield, near Bury (Edleston, Zo0/., 1843). Humphreys and Westwood, in 1843, note the species as having been recorded from Devonshire, Corn- wall, Isle of Wight, London, Warwick, Worcester, Twizell, Cum- wheaton, Cumberland, and Cramond, near Edinburgh. One is recorded as having been taken in June, 1846, at Lewes (Weir), another near Faversham (Horsley), and. one on September rst, 1846, at Rainham in Kent (Longley). None were recorded then until July 22nd, 1854, when a specimen was taken near St. Margaret’s Bay (Thorne), and in 1855 a few larve were found in mid-August by Smith at Deal, whilst one other larva is recorded from Devonport on September 5th by Hayward. The later records, particularly those relating to the 1859, 1870 and 1888 immigrations, are dealt with in the paragraph on “Times of Appearance.” TIME OF APPEARANCE.— Usually in May and June, (more rarely in July) after hybernation as pupa; occasionally imagines are disclosed (without forcing) in August, September and October of the year in which pupation takes place, after a pupal period of only two to four weeks. Its appearance, however, is so irregular that one may often observe larvee and imagines at the same time (Bartel). As bearing out this statement, Ochsenheimer (Dee Schmett., iv., p. 177) notes that Treitschke found 3 larve on the Schotenweiderich on July 2nd, 1816; these pupated, and one produced an imago after I7 days only, whilst the others emerged (gf and @) after being exactly a year and 17 days in the pupal stage. Thurau notes (Berl. Ent. Zeits., liv., pp. 19-20) that a few C. gall pupe produce imagines the same year, that he has observed that larve pupating before July 15th emerge after some two weeks, the others not till the next year. In Britain immigrant imagines generally appear in July or August, usually at a long interval of years. These lay eggs from which larve are obtained in August and Sep- tember, the pupe being usually forced in the winter, or allowed 196 BRITISH LEPIDOPTERA. to remain under shelter till the following spring, and it is very rarely, if ever, that any pup live throughout the winter, in nature, in the British Isles, and produce imagines at the normal time in the succeeding year, although a few do so in confinement (antea, p. 191). The practical absence of records of specimens taken wild in 1836, 1860, 1871 and 1889, the years following those in which the species was abnormally abundant in Britain, is evidence of this. In its more southern haunts the species is, more or less, double-brooded, the imagines appearing in May-June, and in fewer numbers in August, but we suspect that the imagines that reach us belong rather to a late-eemerging early than to the later brood. Of British-reared examples, Head states that a few autumnal imagines usually emerge after a pupal period of from three to four weeks. As we vet further north the insect becomes apparently permanently single- brooded, appearing from late May to July, although, wherever immigrants appear, the more rapid-feeding progeny attempt to produce a partial second (or later if the immigrants themselves really belong to a second) brood. In Bukovina there are two broods (Hormuzaki) ; May, and again in July and August (July 7th-August 17th) in two generations, in Roumania (Caradja), May and June, and again in August, in Bohemia (Nickerl), May and June, and again in August and September, at Buda- pest and Eperies (/es¢e Bartel). The following southern records suggest a second brood, zz., July and August in Tuscany, September in Lom- bardy, commencement of September in Hermannstadt. Ofpartial double- broodedness we have the following—in Saxon Upper Lusatia in May and June, but every large brood produces also a few imagines in August (Schutze), some emerge in August at Munich only two weeks after pupa- tion (Kranz), May and June, and again in August and September, at Baden (Reutti), in May and August at Mombach (Bartel), in June and August-September in Alsace (Macker); whilst larve in May, imagines in August and October at Schwerin, August in Debreczen, end of July at Noworossiisk on the Black Sea, also suggest double broods, and we also have to consider such records as May and June at Sarepta; June in the Altai district, June and July in the Kouldja district from 300o0ft.—goooft., whilst, in the far east, June is noticed for Fujisan (Pryer), and Juiy at Tsuruga (Leech). May to July rare, is given for Eutin, May and June at Bremen, June and July at Crefeld and in the Netherlands, May to August at Elberfeld, May and June rare at Brunswick, &c., the whole of the latter German localities possibly being included in the immigration area of the species. Fritsch gives dates for Austro-Hungary from May 15th- July 19th, also possible second-brood emergences on August 27th and September 4th at Salzburg, and October rst at Vienna. Frey notes the species as occurring in the early summer throughout Switzerland, but Nageli took it at light at Zurich, on August 25th, 1895. Anderson observes that unforced pupz, obtained in 1889, from Switzerland, pro- duced imagines on July roth, 1890, and following days, whilst Colignon records one as late as October 8th, 1898, at Namur. The following list of captures in Britain excludes records of examples bred in confine- ment, which will be found /avéed, pp. 191-193) under the head of “ Forcing Pupz,” and also excludes the earliest dates, already mentioned under the head of ‘“‘Summarised history of the species as British” (anéed, p. 194) September 15th, 1842, at Whitefield, near Bury (Edleston), Sep- CELERIO GALLII. 197 tember rst, 1846, at Rainham (Longley), ?

Hutbnet’s original diagnosis reads ( Verz., p. 137) as follows: The forewings on the costa with cloudy spots; the body at the sides adorned with black and white cube-shaped spots—Ayles galiz, Schitt., H. opheltes, Cram., H. zygophylli, Ochs., H. hippophues, Esp., Hl. nicaea, Prun., AH. euphordiae, Schiff. Stephens, in his application of the Hutbnerian names to the British species (Lest of the Specimens of British Animats in the Collec- tion of the Brit. Museum, v., p. 28) notes euphorbiae and gallii as belonging to this genus, but it was not until the publication of vol. 11 of this work (azz/ed, i1., p. 355) that ewphorbiae was formally constituted the type. Kaye’s diagnosis (zx /it¢.) of the limited genus reads as follows: : Head closely set on shoulders, eyes not large (except in tropical races). Fore- tibize with spines weak and almost uniform size. Forewing with costa very slightly curved at base, straight to origin of nervure 7, then sharply curved to apex ; hind margin evenly curved to termen (in exotic races, slightly excised immediately below apex) inner margin slightly curved upwards for half length of wing. Nervure 5 from considerably nearer 4 than 6; 9 given off from about three-fourths length of cell. Hindwing short, apex bluntly pointed in ¢, almost rounded in ¢. Costa evenly and boldly curved to apex. Inner margin evenly curved to nervure 3, strongly excurved to nervure 10 and straight to anal angle. Nervure 8 curved almost evenly from base; 5 nearer 6 than 4; 6, 7 from upper angle; 3 from very close to 4. Disco- cellular variable from flat to strongly S-curved. Forewing with a more or less well- defined fascia; very broad at inner margin, with a dark discoidal blotch which nearly always lies within the tascia—//jles (type euphorbiae). We have, of course, only one species, ewphorbiae, in this genus, with a shadow of a claim to be considered British; this species appears to be no longer sedentary in the British Islands.

[In fiessdith: ed. p. do02, ““ilava” is changed to “pallida” and “ pur- purascente” to “rubra,” whilst Linné further adds: ‘ Ale superiores, basi angustate; puncto nigro, in medio disci, minimo; vitta longi- tudinalis ex tribus coadunata.

Anterior wings olive, with the median area and outer margin pale ochreous-grey, leaving the ground-colour to form a wedge-shaped fascia from apex to inner margin, a basal patch, a ~ discoidal patch and a small costal patch nearer apex, the three last-mentioned united by a narrow costal streak of ground-colour ; basal patch of white scales, an inner marginal basal black patch just below; inner margin edged with a fringe of white scales; fringes of outer margin unicolorous with outer area of wing. Posterior wings red, with a black basal patch and somewhat narrow black submarginal band; anal area white; fringes white. SEXUAL DIMORPHISM.—The @ is decidedly larger than the ¢. This appears to be so at any rate in any set of specimens supposed to be of the same origin, but the individual variations are so great that one cannot with confidence say more than that it appears to be so. The antenne appear to vary from r1mm. to 13mm. in the g, and from romm.—i12mm. in the ?s, but the average difference for specimens of equai size of each sex is nearer 1°5mm. than 1'omm. The 2 antenna looks very decidedly more slender basally than that of the ¢, and, therefore, more clubbed. ‘This seems to be partly actually the case, more a result of the hair-pockets of the ¢ antenna giving it a more uniform appearance than it really possesses. The ? is more robust and carries the greater width for four or five abdominal segments, whilst that of the g tapers almost from the base. The first tibial spur is longer in the ¢, 2°omm. to 16mm. inthe 2? ; the comb is better developed, but not more than in proportion to the larger spur. The abdominal fan is very small, arising from the usual position, vzz., an offset of the ventral abdominal plate immediately below the first (second?) abdominal spiracle, it arises from a minute area, about -3mm. long and ‘o7mm. wide, and is so small that one says at first view it contains perhaps two dozen hairs, actually it contains about 100, the hairs are yellow-brown and about zmm. long, the pocket-like fold containing it extends down through the following segment and is well-developed (Chapman). GYNANDROMORPHISM.—The only gynandromorph of which we can find any record is the following: a, Left side ¢, right side 9. Left wings smaller; the body perceptibly divided by a median line, the left side green, the right reddish; palpi and legs white ; the abdomen female (Germar, Ahr. Fn. Eur., fasc. 1, tab. xxvi; Rudolphi, P54) Surm.,p. 340; Hagen, S.2.Z., xxil., p. 271). VARIATION.—The variation of this species is highly interesting and suggestive. Not only is there an abundance of minor aberrational 204 BRITISH LEPIDOPTERA. development everywhere, but the facility with which it appears to respond to its widely differing environments has led to the formation of a great number of striking local races which differ greatly from each other, and represent probably incipient species. The so-called minor aberrational variations both in tint and markings are such that a sort of polymorphism is m existence in many localities, few examples being precisely similar. The ordinary red tinted aberration occurring almost everywhere with the type is known as ab. rudbescens, but in almost every locality forms occur which may be described as follows : With the lighter areas of the forewings of a pale ochreous-grey=euphorbiae Linn. With the lighter areas of the forewings of a pale ochreous-grey, but much suffused with black scales=ab. suffasa, n. ab. With the lighter areas of the forewings tinged with reddish=ab. rubescens, Garb. With the lighter areas of the forewings bright red=ab. (et var.) grentzenbergi, Staud. With the lighter areas of the forewings bright red, but much suffused with black scales=ab. ra fomelana, n. ab. Stichel ( Lusekten Borse, 1903, P. 13) gives the following summary of aberrations he has noticed (no. 1 coming from Austrian- Silesia, nos. 2—7 from Bohemia) : 1. Forewings and hindwings with uniform smoky ochre-yellow ground- colour, hindwings showing only a quite faint reddish tone. 2. The olive-coloured oblique band of forewings very narrow anteriorly, &c. 3. The distal costal-spot of forewings only quite faintly expressed. 4. This spot somewhat comma-shaped. 5. Ground-colour very dark, especially the distal part of forewings, numerous black scales observable between basal spot and oblique band on the inner margin. Hindwings dusted with blackish. 6. Forewings covered all over with blackish spots and strokes, especially strongly on costa and in distal area. 7. Black submarginal band of hindwings reduced to a narrow zigzag line, A large red-tinted Italian race is known as var. paralias, whilst a smaller and intensely red, race from Capri is known as var. grentzenbergt. A very dark aberrational form is known as ab. esw/ae, whilst one, in which the red parts of normal ewphorbiae become yellow, is known as ab. /afiéo/it. Bartel considers (Pal. Gross-Schmett., \1., p. 82) that this insect is one of the most variable of the Phryxid species, and reiterates the opinion that it may be still in the process of evolution, and that the various forms may not for centuries become changed into species with fixed and constant characters. ‘Treitschke observes (Die Schmett., X., p. 131) that examples smaller than Theretra porcellus and others far surpassing Phryxus livornica in size are not at all rare. Oberthiir notes that the Brittany examples are of small size and pale in colour, and that he has a specimen from Brest in which the normal rose-colour of the hindwings is, on one side, replaced by white. Bartel further adds that specimens from Sicily are larger and much darker than those from central Europe; the forewings dusted with blackish, the red of the hindwings much darker and the black band before the outermargin of the latter very broad. Examples from Greece are also, he says, characterised by their larger size, and sometimes reach a wing expanse of 87mm., thus surpassing those from all other parts of Europe. Galvagni notes a very dark example from the Statzer-Thal. By HYLES EUPHORBIA. 205 Treitschke (/oc. cz¢.) an aberration is described with exceedingly Jong antennz, which probably only relates to a crippled specimen. Bartel further notes that Heyne has also shown him a specimen in which the antenne are nearly double as long as normal. Ochsenheimer mentions (oc. cif., 1v., p. 181) a very interesting aberration whose ground colour on the forewings is much mixed with blackish atoms and has a stripe of like colour running obliquely from costa to the inner- margin, whilst the red central band of the hindwings is coloured dark brown in the outer half. This specimen, which was in Ochsenheimer’s collection, might form, Bartel considers, a transition tothe much disputed ab. esu/ae. A further aberration from the collection of Bornemann, of Magdeburg, is described (and figured) by Ribbe ( /77s, i1., p. 186, t. 4, f. 4) as follows: ‘‘ The specimen differs from typical D. euphorbiae princi- pally in the very dark coloured outer margin of the forewings. Their light ground colour appears only in a narrow waved band, running from the apex to the middle of the inner margin and internally somewhat shading off into the dark costal colour, otherwise the forewings are dark ; the black band of the hindwings extends as far as the outermargin ; the underside is correspondingly coloured and marked to the upper, and darker than in normal D. euphorbiae ; epaulettes internally white margined. ‘The example was bred at Magdeburg.” He further notes that there is also in the Museum ftr Naturkunde, Berlin, in the Maassen collection, a large specimen of DV. euphorbiae with the forewings much darkened, which may likewise be regarded as a transition to ab. esulae. Rey observes (Lerl. Ent. Zetts., liv., pp. 19-20) that examples bred in the autumn from pupz of the year are smaller and duller than usual, Himsl that an imago reared from a 19-day old pupa was paler than usual. Newman’s figures (£7/. Mag.,iii., pl. vi and ix), and those of Curtis (Brit. Ent., v., fo. 3), made from Devonshire examples, and supplied by Raddon, suggest that ab. rwbescens was a common form among those formerly reared in Britain. Curtis notes (loc. cit.) that ‘‘the male has less black in the underwing than the female, and an aberration of the former sex has occurred with the fascia of the inferior wings of a dark rose colour instead of black.” Stephens says (J///us., i1., p. 125) that “the colour of the wings varies much ; in some specimens the rosy tint is remarkably vivid and powerful, in others, it is somewhat obscure ; the marginal fascia on the posterior wings also varies; it is sometimes entire, at others deeply indented on each side, and occasionally very narrow or very broad.” Scheffler of Carlsruhe has fed larvee of HV. euphorbiae on oak, and Ernst Heyne, who saw the imagines resulting from this experiment, says that three of the specimens were very pale in colour, whilst one example was distinguished by its very dark colour. Borkhausen notes (P/ezn. Mag., i., p. 317) that specimens taken after the hard winter of 1789 were very pale, as were also those of Amorpha popult, and, as he bred only white-grey ylotcus pinastri that year from wild pupe, he thinks the cause was climatic. a. ab. helioscopiae, Selys-Longchamps, ‘‘ Ann.

It is normal except that the specimens are suffused with reddish, the pale portions of the forewings being cherry-red, the colour especially well-developed on the marginal band ; the outer margin of the central diagonal almost always without red, whilst the red of the hindwings and underside is usually more intense. The larva typical, except that the orange-red markings pass into a dark carmine red, This form is very abundant in a dry meadow on the banks of the Sukiel river between Bolechow and Bubnisczze, and is here almost the only one developed—some 90 per cent.—so that, in this restricted locality (and certainly in many others), it has become a variety, whilst in most localities this dark form of the larva only occurs singly. The larvee feed only on Euphorbia cyparissias and refuse other Euphorbia species, larvee from Lemberg dying on &. feplus. This renders Pallas’ remarks interesting : ‘« Aliquoties Majo in campestribus ad Volgam (et Namaram ?) circa Euph. pilosam et floribus volatu suspensa interdiu (in Galicia never by day) larva ad Jaicum passim in eadem et alia minore euphorbia Inderskiensium montium. Frequens etiam in Dauriae euphorbiis. In epilobio Sibiriae copiose 1770. pilobium angustifolium et palustre, idemque Galiwm verum depascitur Larva 1770. In Sibiriae Euphorbiis frequens larvaque saepe intra mensem edit sphingem (with us only one generation) ; quum alibi nunquam nisi post hiemem vel intra duos (never with me). . . . S. euphorbiae larva Evonymo nutrita, dedit Sphingem obsoletissimi coloris sine ullo rubore, griseam.’”? Such a specimen is in the Vienna Museum, and forms a transition to D. gal’i. Pallas did not know reddish forms, although he observed the species so often. Our ab. 7zwbescens has often been referred to the beautiful var. pavalias, Nick., and distributed as such. Even Frey calls the reddish specimens from the Jura paradzas instead of rudbescens, but these two forms are, however, not identical, and exhibit important differences at first glance, much more easily observed than described, e.g., var. favalias, is much larger; the dark portions of the forewings are more weakly developed; the large olive-brown spot under the middle of costa considerably larger and horizontally hexagonal; the pale portions suffused with red, whilst, for the particular characters of the hind- wings and underside, reference should be made to the author’s description. The charac- ter of the red is most important, being quite uniformly spread and including also the outer margin of the diagonal, the tint, too, is of a beautiful uniform rose-red [in rubescens it is cherry-red, of about the tint of ‘‘coccineus’’ (No. 58@ in Miller’s ‘¢Table of Colours,” 1860), whilst that of avalzas corresponds with that of ‘* ruber ” (No. 57a, l.c.),]and it appears as if the moth was artificially coloured with red dusting, and the marginal area is never darkened. In both forms the white lateral stripes on shoulder-covers and head are commonly suffused with reddish. The larva of var. paralias were collected on the shore of Lido, and are distinguished from those of the type and ab. xubescens by their dark colour. . . . . Specimens received from Staudinger as parvalias were really only normal south European examples of large HYLES EUPHORBIZ. 207 size, with no red in them*. It follows from Nickerl’s description that these were incorrectly named. . . . . The third red form of this species is grentzenbergi, described from the double-brooded Capri examples. We have one of Staudinger’s original specimens, which is rather small, very dark, the red colour and dark markings most highly developed, and not to be confounded with other aberrations, and most resembles the ab. figured in Berge’s Schmetterlingsbuch and tithymali, Bdy , from the Canaries, a form that is continuously-brooded, flies on the southern limits of the Palzarctic region, and has, doubtless, already become distinct. The ab. rubescens is widely distributed in Galicia—Lemberg, &c. It must not be supposed that all dark larvae produce ab. rubescens ; some very dark larvee from Okopy produced quite normal examples without exception (Garbowski).

Gross-Schmett.,” ti., p. 85 (1899).— Visiting the coast of Austrian-Italy in the summer of 1835, several larvae were found on Euphorbia paralias on the Island of Lydo, near Venice. These were characterised by their large size and darker marking, when compared with the allied larvee of euphorbiae. They were kept without food three days, and then only fed on half-dried plants, and so pupated rather earlier than might have possibly happened; the pupz were sent to Prague, where imagines emerged the following April. Had they been better fed they would possibly have been still larger, but yet were about one-fifth larger than normal euphorbiae. They are similar to the latter in form and colour, but the large rhomboid spot in middle of costa of forewings in exphorbiae, is, in these, from 2 to 4 times larger and forms a horizontal hexagon in outline. In the pale colour red preponderates and the olive-coloured markings are brighter. On the hindwings, where a pale red tint also prevails, the black transverse band runs parallel to outer margin, shading on the inner side into olive-colour, and is much more strongly waved and forms at the anal angle a sharp triangle of olive colour, edged with black, with the point directed backwards, which is also larger and more acutely angulated than in ewphorbiae. On the underside of the wings, red preponderates; the black spot of the forewings is considerably larger and the oblique simply-curved transverse band, passing from the costal margin of the hindwing backwards, which is often double in exphorbzae, is, in this variety, much more distinct, longer, S-shaped, curved from the front outwards, inwards and backwards. The olive-coloured spot at the anal angle is larger. ‘This variety may be provisionally regarded as a new species under the name of D. paralias until someone has compared the larva with that of the typical form of the species (Nickerl).

One wonders whether Garbowski’s criticism influenced Staudinger. 208 BRITISH LEPIDOPTERA. in this form. Bartel adds that it is only to be regarded as a large, light-coloured, sharply-marked form of /. euphorbiae, with a marked pale red tinge: He further points out that Staudinger’s brief diagnosis “becoming red” has given rise to constant confusion between this and var. gventzenbergiz. Galvagni notes (Verh. Z. Z. zool.-bot. Ges., lil., p. 378) that an example was bred at Vienna, July oth, from a larva taken at Pelagosa on June 7th. He also bred the same form from one found on Luphorbia cyparissias at Deutsch-Matrei (Tyrol), but the Pelagosa example differs from this one in having a darker wine-red marginal area of the forewings and deeper-coloured hindwings. The foodplant at Pelagosa may be £&. dendroides, or £. pinea, which also occurs there. At Lussin, Garbowski found it on E. wulfenit (cfr. Verhandlungen, 1898, S.-B., p. 96).

Most of the larve had been stung by Tachinids, but he obtained some 30 sound pupee. These pupze (excepting 9, which are hybernating), in July, but mostly in September, produced moths so different from the ordinary German and other European specimens as to well deserve a varietal name, and I name them in honour of their discoverer. In all of them the light (grey or white) parts (especially of the forewings and the thorax) are more or less bright red in colour. This is especially striking in the broad medial and terminal bands of the forewings, which are always red, even though in one specimen the usual grey colour is here only covered over strongly with red. To be sure, specimens of euphorbiae with a red tint occur also with us, but all my red German specimens are, nevertheless, distinguishable at once from var. grentzenbergi ; in particular, the central area always remains in them more or less grey (white grey) posteriorly, while in var. grentzenbergi it is red; the white lateral stripes on the prothorax and head also are often quite red in the Capri form; the light hairs at the end of the metathorax are always so. The white spots of the abdomen and the white margins of the segments become reddish in a few specimens only. On the other hand, the entire under surface, both of wings and body, is far redder than in even the reddest aberrations of euphorbiae from other localities. Whether the specimens from Capri are so red every year, or whether this is less the case in other years, still remains to be discovered (Staudinger).

In the Haute-Garonne, Caradja records having bred, from normal or dark larve, specimens as red as examples of var. grentzen- bergi from Capri, whilst, from very bright yellow larvz, he bred, in part, very large moths, which are almost normal in colour, but approach somewhat ab. faralzas. One suspects the Haute-Garonne examples to belong rather to ab. rudescens than var. grentzenbergi. Staudinger notes the latter (Cat, 3rd ed., p. 102) as “intensius rubescens.” g. var.

The larva is black and differs little from the dark form of the larva of ewphorbdiae. It has a red dorsal line which becomes yellowish on the segmental incisions. The yellow lateral line is broadened into a spot on the centre of each segment. The two yellow spots on each side of each segment are margined with deep black. On each side of the back are 4 rows of yellow dots. The caudal hom and the head are yellow-red in colour, the former posteriorly blackish. Venter black-grey.

In the summer of 1893, Herz captured some larve on the same plant, two of which produced a gf and 2, the former agreeing with the one bred by Christoph.

The head is larger, and the front portion of the thorax projects farther beyond the costa; the wings are slightly longer and narrower; the fascia of the forewings is much speckled, and there is very little pink in the hindwings; the black marginal band on the hindwings is much more extended, especially at the apex. @. var.

They are, throughout, more blue in tint, and the black of the marginal band of the hindwings is not sharply, but indistinctly black, dull, and, in a measure, grey-black. The ground- colour of the forewings is a dirty (grey) sand-yellow, in the ¢ somewhat tinged with violet (not red); the olive-green basal and middle (costal) spots, as also the broad outer band, are also somewhat weakly tinted with yellow, the latter, indeed, only stands out little from the somewhat lighter violet-grey outer margin.

Probably this pale unicolorous var. ceztralasiae occurs only in the low-lying sand-steppes, whilst the Central Asian ewphordiae from higher ground may come nearer the European form. The colour of var. centralasiae stands in a similar relation to euphorbiae as does D. bienerti, Staud., to D. hippophaes, Esp., and I now hold the former to be a local (steppe) form of hippophaes, for, although the Central Asian bzenerti never shows the small black dot at the end of the forewings which zppophaes always has, yet it shows transitions in colour from one into the other, and, particularly, the larvae of dzenertz, are almost entirely like those of hippophaes. DISTRIBUTION. —AsIA : Samarkand, Namangan (Staudinger), Pamir—Oche (Grum-Grshmailo). Bartel notes (Pal. Gross-Schmett., i1., p. 89) that this striking local form is much paler than the type, and is recorded from Turkestan: Samarkand, Namangan, Osch, and Fergana. It appears in May, and is said in its limited steppe localities to be somewhat common. Kaye observes that the only example in the British Museum collection, is smaller, and with the fore- and hindwings much more rounded than in typical A. euphorbiae. Both fore- and hindwings, too, are much greener. The discoidal blotch is much more rounded and distinct, and there is no mark beyond the blotch near the costa. The black marginal band of hindwings is quite even on the outer edge and well-curved, following the shape of wing, altnough this is, in all the forms of 4. euphorbiae, a much more variable character. It is difficult on a single example to enter into the question of the specific value of this insect. Pungeler (Ber/. iver, XiVvil., ~). 237), on account of the great difference in the preserved larvze which he possesses (from Askabad), is decidedly of opinion that it is a good species, especially as HZ. ewphorbrae also occurs in the same neighbourhood. Staudinger treats the following as a local race of H. euphorbiae. It appears to us to be, however, a distinct species, and we give the diagnosis simply for reference— HYLES ROBERTSI, Butl., ‘‘ Proc.

On the upper surface of the primaries this species most nearly resembles D. dahizz, of the secondaries D. hippophaes, of the body D. esulae, and on the undersurface D. lathyrus. The olive tint of the thorax and the markings on the primaries are greener than in any species with which I am acquainted. FOODPLANT: The larva of this was found on almost every plant of a species of Huphorbia, which is very common on the rocky hills here. The larvz are very beautiful and conspicuous, and are very different in colouring according to their different stages of growth. It is quite distinct from a common one obtained in Kashmir, which was found on a different species of Euphorbia, and was abundant at Goolmurg. LENGTH OF PUPAL STAGE: About half the cocoons produced: moths in about: three weeks after changing ; the remainder are still (December 31st, 1879) alive in the pupal state; curiously enough the first larva that changed is among the latter. LARVA: About 3” long when at rest. Anterior segments attenuated, not retractile; skin smooth and soft. General colour black, with white dots and spots; a subdorsal row of large white roundish spots, one on each segment, either yellow, orange or red ; a dorsal stripe varying in colour, but generally the same as the spiracular blotches ; it is, however, sometimes only partially represented, and sometimes absent ; when present, it is broadest at the interstices, where it sometimes differs in colour from the portions between ; feet, bead, back of head, and base of horn either yellow, orange or red, generally the same as the spiracular blotches and dorsal stripe; horn slightly rough, curved, rather longer than the segments, black, with the rear-base either orange, red or yellow (being the continuation of the dorsal stripe, broken by the horn, and is consequently absent in those which have no dorsal stripe); spiracles white and rather narrow ovals ; head globular; belly pale yellowish-green, extending up the interstices to above the spiracles. Kandahar, beginning of May, abundant, all sizes. WARIATION OF LARVA: At the end of May most of the larve found presented a different appearance; the black disappears more or less, and with it many of the small white spots. In some cases the black only remains as a ring round the larger white spots; the ground- colour, therefore, becomes yellowish-green or yellow, varying very considerably ; the horn becomes black at’ the apical half, with the basal half the same colour as the dorsal stripe. The larve are, therefore, exceedingly variable in colouring (the large white spots always remaining the same, however); some specimens are, consequently, so unlike one another as, at first, to appear different species ; every intermediate form, however, being found does away with the idea. HABITAT: The foodplant grows in the nullahs and on the slopes of the rocky hills, and is very common, but scattered ; and almost every plant that now (end of May) has any leaves left on it, has several larvze feeding on it. HABIT OF LARVA: This larva, like others of the same genus, emits a large amount of a green fluid from its mouth on being irritated in the least for the first time, not often doing it a second time. PupATION: This species does not change colour when seeking for a suitable place for its cocoon, which is at or near the surface of the ground, amongst rubbish (Butler quoting Roberts zz ltt). Staudinger makes ( Caz, 3rd ed., p. 102) peplidis, Chr., a synonym of roberisi, Butl., and diagnoses the latter as: ‘‘ Scapulis ubique ee: marginatis, al. ant. grisescentibus.” Hampson writes (/nd. Moths, Pp. 99) “that roberts: “differs from gall@ in the thorax, having two hte stripes, the tegule being fringed with white on the inner side also; the abdomen as in ewphorbiae, forewings as in gad/iz, the hind- wings with the band pinker. Some specimens have the segments of the abdomen fringed with blue scales, and the veins on the outer area of the forewings streaked with white. Kandahar, Simla. Exp. 82mm.” EGGLAYING.—The eggs may be laid singly or in small batches on the tops of the young shoots of the Lwphorbia, one batch found consisted of about a dozen eggs (Harrison). The parents do not seem to exercise much judgment in depositing their ova ; sometimes three or four young larve are to be seen upon a small plant not more than 3ins. high, and no other plant within rooyds. of them ; in many instances again, several small larve were noticed upon HYLES EUPHORBIA. 213 a diminutive plant, while large robust plants close at hand had none on them (Mathew). The eggs are laid at the top of the plants among the soft budding leaves (Melhuish), light green in colour and usually eight or nine near together (Johnson). ‘The eggs when laid, are covered with an adhesive gummy substance, by means of which the 2 fastens them to the small leaves of the spurge (Raddon). In confinement the eggs are laid at the base of the leaves of Euphorbia cyparissias, in small clusters, composed some- times of as many as seven, the single eggs being placed near together, but never touching, and seldom at the point, of the leaf, but generally near the end of a twis, where young shoots are in close proximity (Weismann). OvumM.—Bright pea-green in colour, semi-transparent in appear- ance; nearly spherical in outline; length t'1mm., width 1mm.; one end very slightly broader than the opposite; surface smooth, covered, however, by a small and faintly marked cellular pitting or faceting. [Eggs received from Dr. Chapman.] (Bacot). Green, very small in proportion to the size of the moth, smaller than those of AZzmas tiliae (Bartel). The eggs much resemble those of Lumorpha elpenor, being spheroidal in form, but rather smaller, and of a somewhat darker green. During the embryonic development the eggs become coloured, first yellow, then partly blackish, and, finally, completely black (Weismann). Hapits OF LARVA.—The newly-hatched larva does not eat the eggshell (Sich). When quite young, the larve are always found among the soft budding leaves at the top of the plant, working their way down, eating leaves, stalk, flowers, and seeds, all except the central stem, till they reach the ground when they run off in search of fresh food, leaving behind them a broad trail in the sand in which each foot’s tread may be distinctly traced. Stripped plants are a sign that the larve are gone but they will be found not far off ; if leaves be withered they will be underground, but, wherever there is a green-looking bed of Huphorbia, you are sure of a score or two. They prefer the seedvessels and young stalks as these contain most of that milky juice which is their great delight, and, if a twig be broken, they will fasten on the broken end and lick up the milk as it oozes out. The seedvessels they take between their front legs, and, raising themselves into the SfAzmx posture, gnaw away at one till it is demolished, just like a monkey with an apple, their feet close before their mouths; if interrupted when feeding they turn round with the greatest fury and spit out a quantity of green liquid of an acid and disagreeable smell, similar to that of the spurge-milk only worse. When a larva after rambling about finds a fresh plant to its taste it sets to work at once upon the bottom leaves, merely raising up its head from the ground, and devours all within its reach, before proceeding to climb the stem ; these bottom leaves are, of course, very inferior, but were the large larve, who are old enough to travel, to mount up to the top at once and eat all the tender shoots, all the little larve just out of their eggs would be starved. A larva never turns—it goes up or down according to circumstances, but only one way; they must swallow large quantities of sand, for, however sandy a leaf may be, if it be fresh they never reject it on that account. ‘Trails and frass are proof positive of the 214, BRITISH LEPIDOPTERA. recent visit of larvee even when the latter are not visible as they are soon covered with sand. They run over the sand with great ease in search of a fresh plant and are very active between 3 p.m. and 6 p.m. They are most abundant at St. Pol de Léon during the first week of September 400 being collected in three days. Curtis states (on the authority of Raddon) that the young larve are not easily discoverable, but that, when large, they are so conspicuous that their numbers are reduced by marine birds which feed upon them; they can also, at this stage, be traced by their frass and’ are sometimes to-be scen- nestinpeee the extremity of a culm of a small rush, and, at Braunton Burrows, used to be fullgrown about the middle of September. In the Channel Isles near St. Helier, the larvee were formerly collected in August (Batho), whilst at St. Poldu, Harrison reports that larvee were abundant at end of July (28th-z9th), 1897, and that pupation commenced by August 4th, whilst John found larvee in the Forest of Fontainebleau, August rst-4th, 1872, which, being sent to Buckler, pupated between August gth-18th. Chaumette observes (Zool., 1x., p. 3158) that the larve, known to Swiss children as ‘ Chenilles de Tithymali,” are usually more or less gregarious, that as many as 150-200 may be found in one spot, often fewer, but rarely solitary ; he further notes that, in feeding, they gnaw the lower leaves of the spurge from apex to base, and eat very rapidly. We have repeatedly found the larve in Switzerland, Dauphiny and Piedmont, and have also noticed this gregarious tendency, and, large and conspicuous as these larvyze are when looked for, it 1s easier to walk over them than see them at a casual glance. Their lazy habits are beyond belief, and their powers of eating extraordinary. The larva will stand on a stem of the foodplant, eat the leaves one by one, commencing at the top, as well as the stem itself, only stepping backward as the stem becomes shorter, and at once reach forward to the nearest leaf. Some in confine- ment did not move during the night, but were found in the same position as they had taken up the previous night. Between Evolena and Villar they were exceedingly abundant in early August, 1899, the smaller ones clinging to, the larger stretched across, the foodplant in the morning. sun, and again them je@ener similarity to their surroundings was noticeable, due, it would appear, entirely to the effect of light and shade on the hues of the larva, producing a general resemblance to the colour of the leaves and blossoms of the spurge on which they rested; there was no special part of the plant to which the larve bore a special resem- blance, and a larva, practically invisible in one position, often became quite conspicuous from another standpoint. Merrifield observes that, in the Vals-Platz, they are conspicuous enough, lying across their foodplant or sometimes on a grass bent arising out of it, and are very sluggish, except, occasionally, when crawling from one patch of their foodplant, nearly eaten down, to another. After commenting on the conspicuous spots of these larvee, the same observer details (yz. Rec., xii., p. 320) an experiment tending to prove their inedibility as far, at least, as fowls are concerned. Weismann, on the other hand (Studies in the Theory of Descent), states that a lizard that would not eat a larva of Celerio gallit, at once attacked and swallowed a large larva of Hyles euphorbiae. Mathew states that, in Malta, the larve are much attacked by cen- HVYLES EUPHORBIA. 915 tipedes and that carnivorous beetles prey on them at night. Buckler observes (Larvae, &c., 11., p. 31) how the appetites of some larve that he had from Fontainebleau seemed insatiable, each larva embraced the seaspurge with all its legs, ate voraciously, and, at length, when compelled to stop, it would go to sleep without change of position and with a partly-devoured leaf in its jaws, and then, after a few minutes’ repose, it would wake up, finish the leaf, and attack whatever came next—leaves or seedvessels—most vigorously, there was no walking about, the only movement was a step or two backward as the stem shortened beneath its jaws ; during eight days he was busy picturing them, and none sulked or shrank when the sun shone on them, or when, for closer inspection, they were taken in the hand, only, as each matured and ceased feeding, it grew active and lively, exhibiting its capacity of walking at a great pace for a day or two before settling down to its change. When handled, or irritated, the larve exude from the mouth a large quantity of dark green fluid that smells strongly of its food- plant, and often throw it for some distance by means of a sudden jerk of the thoracic segments. Harrison observes (L£ut. Rec., 1x., P2023) that, on, July z8th-2o0th, 1897, he took some 120 larve feeding on Euphorbia paralias on the coast of Brittany at Le Poldu; the larve were in all the various stadia and very abundant. ‘The young iImaceumtil im the ard imstar, rested on and ate the tops of the young shoots, eating through the stalks below the seeds, so that the sand all round the eaten plants was covered with the seed-heads, but, at the 3rd or 4th moult, the larve feed on the leaves at the base of the red stalks. The larve seemed always to occur in pairs, although the only batch of eggs found consisted of about a dozen. He further observes that the fluid exuded by the larva causes a very violent irritation if it gets into scratches or into the eyes. The larvee are sometimes found in great abundance and vary exceedingly in size at the same time in the same locality. Eaton observes that between April 27th and May 4th, 1894, near Biskra, he saw what he estimated to be between 1000 and 2000 larve of different ages, some in the blackish juvenile stage, others 3ins. long, and states that, standing still anywhere, where the foodplant grew, he could see 4—6 larve without stirring, but, in exceptionally favourable places, they were much more numerous, and, within the space of a quarter of an acre, some 500 were actually counted; a few bushes of Euphorbia guyontana, oc cupying each about a square yard of ground, had on them over 20 or 30 larve apiece. White observed them of all sizes and in great numbers at Capri in May, 1866. In Transcaucasia, according to Romanoff (Mém., 1., p. 70), the larve of A. euphorbiae appear in certain years in such great numbers that they cannot find enough food, and must perish through hunger. Thus, in 1879, on the tailway from Tiflis to Kodigori they appeared in such abundance as to astonish travellers in the district. Chapman notes (47+. Rec., ieep- zor) that, on the “lLandes,” he observed the stems of Euphorbia eaten in such a manner that he thought he had found a larva of H. euphorbiae where there was none, the bases of the leaves appearing as round coloured spots, an appearance that he con- siders the larve obviously mimic. He adds that, in Capri, the larve feed openly and abundantly on a shrubby Zuphorbia, where its aspect 216 BRITISH LEPIDOPTERA. seems to make it intentionally conspicuous as a warning to enemies. Mathew writes (zz Zt.) that the abundance of the larve from April to December, at Malta, suggests continuous-broodedness in that locality, imagines as early as April 14th, larve about a quarter grown on April 27th, and larve continuously on until December Ath, when some were quite small (possibly the larve of the April imagines), helps to bear out this view, but they are most abundant from July to October, and are sometimes so numerous that they devour nearly all their foodplant, and may be observed -wandering about looking for more; many of these, he thinks, must die of starvation. The larve collected produced imagines very quickly as a rule, but some examples of one lot, taken in the autumn of 1897, remained in the pupal state for more than 12 months. They began to emerge in June, 1898, two appearing on the 17th, and others during July, August, and September, whilst the ship was in various parts of the Mediterranean; the last, however, did not come out until after his return home, and emerged at Dovercourt on November 12th. The following table gives some interesting details : DATE, LOCALITY. REMARKS. Nov. 2, ’62} Gibraltar Took 7 fullgrown larve on Z. paralias on sandhills on the ‘‘neutral” ground.

D7 As showing the long period over which larve are to be found in France, we may note that Réaumur obtained fullgrown larve near Paris on July 15th, which pupated directly afterwards; he further observes that larvee also were extremely common between Bevis and Langés on the banks of the Loire in early September, very few pupated before Septem- ber zoth, and imagines did not emerge until the commencement of the following July. The larve are usually found in July and August on the west coast of France, and they used to be most abundant in July and August in Jersey before they were exterminated there. Chaumette, too, observes that, at Lausanne, larve occur from the middle of June to the end of October, whilst Bell reports that, in the neighbourhood of the Bilbao river, larve are very abundant in June and again in September. Jones observed larve from July 24th-27th, 1894, at Gerolstein in Rhenish Prussia, and Walker in June and October in the cork woods of the Gibraltar district, whilst Bachmetjew notes that they are common everywhere in the Sofia district in August and September. Eaton says that larve were exceedingly abundant from April 27th-May 4th, 1894, near Biskra, but from here no summer or autumnal records are available. We may add, as bearing on the continuous-brooded- ness of the species in the Mediterranean, that Fletcher found the larvee common on October 5th, tg01, at Lemnos, and a few fullfed ones at Volo as late as November 3rd, and that Mathew has found them commonly on both sides of the Sea of Marmora in October and November. Larva.—Sirst instar *: Largest 8°75mm. Head, legs, scutellum, anal plates, tubercles and hairs black ; the skin-surface dusky green. The larva tapers slightly from the 7th and 8th abdominal segments towards the head ; the subsegments appear to be 6 on the meso- and metathorax, and 8 on the abdominal segments, but the first three subsegments are obscure and appear as a large ist subsegment, followed by 5 smaller ones. The skin-surface granular, with no trace of spicules to be seen. Head dull black, the surface finely granulated with usual hairs. Scutellum and anal plates black and chitinous. True legs shiny black; small black chitinous plates at base of prolegs; caudal horn short, blunt, only tapering slightly, black, chitinous, thickly covered with small, rather broad- based thorns that are apparently analogous with the _ prickly- looking hairs that usually cover the horn in other species, the hairs at summit (1of 8th abdominal) black, and short in comparison with those of such species as Sphinx ligustrt and Amorpha populz, but much longer than the other body-hairs, blunt-ended, but not enlarged nor notched at tip, their bases quite a considerable distance apart owing to the blunt character of the horn. The tubercles are arranged as follows: i and ii are arranged trapezoidally on separate subsegments on the meso- and metathorax, and only a little more than half the distance apart of i and 11 on the abdominal segments, where they are set at corners of an oblong rather than * As to the number of moults, Sich notes (Zzt. Rec., xv., p. 68) of the dates of the moults of a larva he reared, and that hatched August 1oth, 1901, as follows : First moult, August 17th; second moult, August 26th (when it appeared to miss the third and reach the fourth phyletic stage); third (and last) moult, September 2nd. It ceased feeding on September 14th. 218 BRITISH LEPIDOPTERA. a trapezoid, and separated from one another by two subsegments (being placed on subsegments 2 and 5); on the meso- and metathorax ill iS a twin-haired oval tubercle, and there is a single-haired subspira- cular (? v) on the anterior margin of segment. The 1st abdominal differs from all other segments in that iv and v sometimes form a twin-haired, oval tubercle *, directly beneath the spiracle, whilst the spiracle and iii (directly above spiracle) appear to be further forward than on the > other segments, and are apparently situated on the 3rd subsegment. On the other abdominals 11 is directly above the spiracle apparently on sub- segment 4; Iv is directly beneath the spiracle, and larger than v which is quite close to the anterior margin, apparently on the rst subsegment, and slightly above the level of. iv, but they are both clearly situated on the lateral flange which is, however, only shghtly marked. Hairs very short and stumpy, but apparently blunt-ended and _ neither knobbed nor forked. The 8th abdominal spiracle is much the largest, the 7th abdominal comes next and that on the prothorax next, whilst those on abdominal segments 1—6 are not more than half the size of that on prothorax so that the disparity in size between those on the 7th and 8th and the other abdominal segments is very great. There is a pale narrow mediodorsal line. [Bacot. Described from larva received from Chapman, preserved in formalin.|] Second cnstar (still wanted). Zhzrd instar: Plump, full-bodied, but not squat; tapering gradually from 3rd abdominal segment to last thoracic, and thence more rapidly to head. ‘The head is small for a well-grown larva of this size, rounded and but slightly taller than wide. The horn is short, upright and pointed, carries two bristles at sum- mit, and has a thorny appearance, due to numerous smaller bristles, and their conical bases scattered upon it, the skin of horn is shiny and chitinous-looking, black for upper ‘two-thirds, yellow or orange at base. Thetrue legs are black. There are 8 subsegments to each segment, the first three of which form one large division which ap- pears to present both a structural and a colour character. The larval colours are very brilliant and sharply contrasted, consisting of vivid green-yellow with intense velvety black and white spots. The head is black and orange, the crown and face black, with a varying area of orange, which may be only a narrow streak or a broad band or belt, running horizontally round the sides of the head and across the face, just above the mouth. The body colours also vary in the proportion of green-yellow and black, in some larve the black area being much _ increased. There is a broad bright yellow mediodorsal band from head to base of horn, it commences again behing the horn and is continued to the anus; the ground-colour of the * Reference to larve of Zheretra porcellus and Sphinx ligustri in Ist stadium shows that in these iv and v are well separated on the Ist abdominal, both are on the lateral flange at or near the same level. Larve of Celerio galltt and its allies in this stadium are unfortunately not at hand for reference so that I cannot say whether this marked aberrational character of united iv and v in Ayes euphorbiae is ever found in them (Bacot). Chapman notes that the larva of 7. euphor biae examined by Bacot must have been aberrant, that he has examined two larva, in both of which the arrangement of iv and v onthe Ist abdominal is such that, although brought nearer together, iv and v still remain quite distinct and at some distance from each other. A subsequent ex- amination of 8 examples in Bacot and Chapman’s possession results in showing that tubercles iv and v on Ist abdominalare: (1) Left conjoined, right normal. (2 ) iter conjoined, right approximated. (3) Left normal, right conjoined. (4) Left conjoined, right conjoined. (5-8) Normal on both sides (vide, Lint, Rec., xv., April no.). HYLES EUPHORBIZ. 219 larva is then black to the lateral line, broken, however, by a series of yellow or green triangles of smaller or larger size, with one side vertical against the base of the segment, another side at right angles, running horizontally to the forward apex, which is just behind the enlarged subdivision consisting of the first 3 subsegments, the third side slopes obliquely backwards at an angle of about 45°. On the thoracic and on the 1st and znd abdominal segments the front apex is cut off, giving this yellow or green area an irregular shape. Situated on the enlarged 1st subdivision of the segments is a subdorsal series of brilliantly white rounded or oval spots; in some larve there is a second row of much smaller spots beneath and rather anterior to the spiracles, in other larve this is quite absent. The secondary body-hairs (analogous to the shagreen-hairs of other species) are minute, very short, black bristles with their bases not raised as mammillz, but, where they occur on a_ black skin area, other than on the 1st enlarged subsegment or in near proximity to the subdorsal white spots, they are surrounded by larger or smaller white specks. It is also curious to observe that, where the black encroaches on the yellow or green (paler) areas, it always does so at first as streaks and dots, at mid-distance between the hair-bases, as though there was some antagonism between the black pigment and the hair-base; it is this feature that produces the tessellated appearance so characteristic of the Eumorphid (Theretra porcellus and HLumorpha elpenor) \arve, and no doubt it is an anaiogous trend that, in Smerinthus and Sphinx, has produced mammillz and pale or brighter coloured areas at the base of the secondary hairs. Whether the primitive Sphingid larva had tessellations or pigmented mammille is doubtful, more probably the pigmented specks of the Phryxid and Sesiid larve represent the primary form. In any case, we may consider that the secondary (shagreen, mam- millary or pigmented) hairs are a phylogenetically old and important character of the Sphingid larva. The spiracles are white, and beneath them is a broad subspiracular stripe, yellow where it is raised and flange-like near the spiracle, but green at the anterior and posterior portions of the segments, whilst beneath is a band of black, speckled with white. The venter and prolegs are green, but the side plates of the prolegs are black. In some larve, and in the 4th skin of most, the black area is much increased, the black encroaching up the segmental incisions, cutting up the ventral area into yellowish or greenish spots surrounded with black, thus giving the pattern so often found in twig-resting larve of various families or superfamilies. ourth mstar : ‘The only change in larve that have assumed the 4th skin, is for the black and white to be increased at the expense of the yellow, the green having merged into yellow. The horn is thicker and rougher. The yellow on the head has deepened into vivid orange, and the medio- dorsal stripe is also orange where it crosses the scutellum. [Bacot. Larve received from Dr. Chapman, early July, 1902.] fifth (Adult) wstar: Very brilliantly and crudely coloured (strongly suggesting warning coloration). In the black ground-colour, and the large yellow shagreen-spots (and the more or less absence of these on the enlarged Ist subsegment), the larva bears a marked resemblance to that of Celerto gallit. Head, anal plates and prolegs red ; a subdorsal series ot large pale yellow spots from prothorax to the 8th abdominal, situated 220 BRITISH LEPIDOPTERA. on each of the enlarged subsegments; the series duplicated by a row of rather smaller spots immediately beneath it, and above the spiracles. The head rounded, inclining to be tall and with a slight suggestion of being trapezoidal, brilliantly red, with a smooth but not highly polished surface; a band of black just above the mouth, the upper portion of labrum and bases of antenne pale yellow, the tips of antennz, lower edge of labrum, and other mouth- parts black; the true legs also black. The body black (duller and less satiny than in C. gall) ; scutellum black; anal plates bright red ; caudal horn red, looking like a piece of red coral, rather upright and blunt tipped (? nibbled by other larve); a dark red mediodorsal band, rather broader where it crosses the scutellum than elsewhere; a broad, bright, rather deep yellow, lateral band, with a series of bright red spots on it just beneath the spiracles, these spots very faintly marked on ‘meso- and metathorax, but quite absent on prothorax. The ventral area with a broad mediodorsal band of pale dirty-looking yellow, broadening on the abdominal seg- ments and including the bases of the prolegs within its area, and ending at the anal claspers. The spiracles white with a black chitinous rim; the prothoracic and 7th and 8th abdominals slightly larger than the others. Scutellum bordered subdorsally by a short stripe of cream colour, a modification of the subdorsal spots present on the anterior subsegment of other segments from mesothorax to the 8th ab- dominal ; the upper spot on the 8th abdominal elongated upwards towards base of caudal horn. ‘The pigment-spots surrounding bases of shagreen-hairs are largely absent from the middle area of the enlarged subsegment that bears the subdorsal series of spots, being almost entirely restricted to a band on the anterior and posterior portions of the segment save for a few on the centre of the dorsum. The mediodorsal band is bordered with pale yellow behind the caudal horn. Hairs black and very small (Bacot. October 3oth, rg01. Larve sent by Fletcher from Malta). ? Third instar:* About -751n. in length; body yellow or yellowish-green in colour; the head small, almost of the same tint as body, with two dark spots on crown, analogous with the dark markings on either side of each body segment, and in which are the white spots that characterise this larva; a yellow-green mediodorsal line, bordered on either side with a fine black and white latticed reticulation, which forms, as it were, two lines edging the mediodorsal, and uniting the tops of the black marks in which the white spots are placed; the spiracular line has more of this reticulation, whilst directly below is a marked yellow subspiracular flange, broken by the segmental incisions ; below this again the black and white reticulation takes the form of two or three white spots, ringed with black at the base of each proleg; the prolegs themselves are green with a dark spot on the outside of each, whilst between each pair is a smoky quadrangular ventral spot, the spots being less distinct, though present, on those abdominal segments without prolegs; the true legs are black. The 8th abdominal segment, bearing the black caudal horn, is the darkest segment, but, whilst the 9th abdominal * These are more or less duplications for comparison with Bacot’s much more complete descriptions immediately preceding, HYLES EUPHORBIA. 221 segment carries a white spot on either side, the 1oth consists merely of the anal flap and prolegs. ? Fourth instar: | Larva moulted between 5 a.m. and 6 a.m. on August 12th, 1899.| ‘The head, thorax, anal plate, prolegs and caudal horn were entirely yellow directly after the iimoult- By 11 a.m., the tip of the caudal horn, the head, and the thoracic segments were considerably darkened, but the fuller dark colour was not obtained till about 6 p.m., 7¢., until some 12 hours had elapsed. The larva exactly ‘75in. long in its old skin, was ‘gin. directly after moulting, the head and caudal horn comparatively large; the skin wrinkled. Head bright yellow, with a black spot on either side of crown; the front edge of prothorax folded so that the white skin, laterally, is homologous with the white pair of spots on the succeeding segments (these two spots united on mesothorax), the prothorax otherwise entirely black; there is a bright -yellow mediodorsal line including the base of the caudal horn; the first subsegment of each segment is black and contains the two characteristic white spots; the remainder of the body-surface now covered with pale yellow and black reticulations (in the form of black rings that include the pale ground-colour), whilst the lateral area is yellower than the dorsal and subspiracular areas ; the subspiracular flange (still broken) is bright yellow, the reticulated area continued below the flange ventrally to the line of the prolegs, which are still yellow, and bear a dark plate externally ; the 9th and roth abdominal segments appear to have separate spots, whilst the strong anal prolegs are yellow with external black plates ; ventrally, the larva is greenish, with black spots between prolegs (also present on abdominal segments 7 and 8) very marked, whilst the characteristic reticulation of dorsum and sides is continued on the venter of the 1st and 2nd abdominals ; the white spots of the reticulation, directly below the flange on the thoracic segments, form a sort of secondary inferior flange above the black legs; the caudal horn still black, the tip blunter. The larva grows to 1’5ins. or 1°75ins. in this stadium. ? Fifth instar (newly-moulted) : [When the larve first enter this instar some three forms are observable; as they become fullfed, the propor- tion of the various colours changes and there are finally scarcely two specimens alike. At the commencement of this instar they are about r4ins. long but they feed up rapidly and quickly, and reach a length of from 3ins. to gins.| (1) Ground-colour green, the . spots on the crown of the head reduced ; the prothorax green, large in proportion to size of head, the black reduced to a lateral mark containing the white spots (united), as on the succeeding segments ; the true legs yellow with black hooks ; the segmental incisions green ; the reticulation fails in part, so that, laterally, a square spot of the ground-colour is left on each segment between the white spots and incision behind ; the dark colouring of the plates on the outside of the prolegs (anal included) is wanting; the caudal horn with a blunt tip. (2) Much more intensely coloured ; the head orange-yellow with a black edge separating it from the mouth; the black much increased on the front of each segment; the mediodorsal line deep orange- yellow as also is the caudal horn, except the tip; the whole of the segments closely reticulated ; the yellow lateral spots (described in the preceding larva) deep orange, but more or less included in the ground- colour; the lateral flange is deep yellow, but the true legs, prolegs, 999 BRITISH LEPIDOPTERA. anus and anal prolegs are orange-yellow; the plates on the outside of prolegs colourless ; the reticulation continued ventrally on the 1st abdominal segment. (3) Head red; the skin of the prothorax, medio- dorsal line, caudal horn, lateral flange, true legs, prolegs, anus, and anal prolegs deep red in colour ; the lateral spots on either side of each seg- ment (instead of being white or yellowish-white) deep yellow ; ground colour of dorsal area very yellow; the black reticulation and black anterior subsegments strongly developed ; the ground-colour of spiracular and subspiracular areas white ; the’ ventral- surface red, with a yellow spot in front of each of the dark ventral abdominal spots. /7/¢h instar (full-grown): 3ins.-4ins. in length. Much variation exists. The wrinkles in the skin (noticeable in newly-moulted larva in this instar) have disappeared, the larva is sleek, smooth, and shiny ; the head (which is large in proportion to size of body directly after moult) comparatively small, and there is a distinct snout-lke appearance about the head and thorax as in the so-called Chcerocampid Eumorphids. Under a lens the whole of the pale (white, yellow, or orange) spots appear to be set in the black ground-colour. ‘The head and segments are covered with very fine dark hairs (shagreen-hairs), the bases of which are very conspicuous in the pale spots just alluded to. The ocelli are placed very low down on the cheeks on the dark area that forms the upper boundary of the labrum. ‘The spiracles make a very fine wide double lip, have a very conspicuous lumen, and are placed transversely on the ist subsegment of the abdominals, above the lateral flange, at the posterior and inferior border of the lower (paler) of the two lateral spots on this subsegment. The anal segment, anal prolegs, and ventral prolegs are covered with short bristly hairs, and there are some short hairs of the same colour as the skin on the true legs. The black hooks of the legs and prolegs are sufficiently strong to tear the epidermis from one’s fingers (Tutt. Described from Evolena larvee August roth, 1899). Avother larva quite fullfed in fifth instar*: The head red rather than red-brown, shining, almost smooth, al- though sparingly sprinkled with minute pale yellowish hairs ; mouth- parts black, edged above the labrum with yellow, and fringed with longer pale hairs; two small black patches at bottom of cheeks look as if part of mouth; on edge of each patch are 5 red-brown ocelli in form of a concave curve (the 5th very low down at base of antenna), a 6th ocellus in normal central position; the antenne short, 2-jointed, pale, on a pale conical base, the upper part of which is movable with the antenna, the terminal hair probably homologous with another joint. The prothorax small, but forming a hood over head, broadly red centrally (commencement of the mediodorsal line), but with the ground-colour black, shiny, and having a yellow transverse patch at the front, on each side of the mediodorsal line; prothoracic spiracle formed of two closed creamy-white, closely appressed, lunular halves, with fine, slightiy raised, black external rim; an oblique, red, tumid, muscular flange on each of the thoracic segments, each connected with that on the succeeding segment; ventrally, the thorax is pale reddish, i; * This description was made quite independently of, and earlier than, the preceding. In such an interesting and variable species we have no hesitation in giving our readers as much material for comparison as is available. HYLES EUPHORBIA. 223 the true legs red, with a single strong black claw, a ring of black hairs at joints. The thoracic segments gradually increase in size, and this enlargement continues to the 3rd abdominal segment; then the seg- ments are pretty uniform to the 8th abdominal, which carries the caudal horn, the goth is contracted, the anal flap reddish, the anal prolegs arising from the central portion. A red mediodorsal line extends from head to anal flap, the caudal horn red with black tip, and moderately large in proportion to the size of the larva. The ground colour of the body is black, thickly covered with yellow spots arranged so as to run transversely in circles around each subsegment except the 1st; this 1st subsegment bears two very characteristic marks: (1) A pink oval patch increasing in size from the prothorax to the 8th abdominal and placed subdorsally, z.¢., on either side of the mediodorsal line and forming two longitudinal rows, 11 in number (although that on the prothorax is modified into a linear mark on the front edge of the segment). (2) A series of yellow spots irregularly oval in form (although some incline to quadrangular) extending from abdominal segment 1 to abdominal segment 4g, becoming on the latter segment a large longitudinal patch, and placed above and a little in front of the spiracle on each segment. The skin is sprinkled with minute short black shagreen-hairs, at least one in each small yellow spot, the spots being in reality hair-bases, whilst the united yellow spots are united hair-bases; _ there are, however, aS many hairs on the dark ground colour, with- out pale bases, as there are on the other parts of the body ; this structure suggests strongly that the rows of pink and yellow blotches on the 1st subsegments of the segments are formed by a coalesence of a number of these spots into a definite pattern. ‘There is a very definite supraspiracular black-brown seta (iii) on the black area, and another very similar one (iv) below the spiracle on the yellow lateral flange, and one finds, dorsally, strong hairs that may represent i and u, but they are difficult to trace and do not appear to be present on all the segments, nor to have quite the same position ; there appears to be no tubercle v, unless a_ prespiracular Seraeat the iront.of cach segment can possibly be it. ‘The subsegments on the prothorax are ill-defined ; those of the meso- and prothorax appear to consist of a wide rst subsegment and at least 4 narrower ones, but the rows of yellow spots suggest that there may be as many as on the abdominal segments; the abdominal segments, 1st to 8th, appear to have nine subsegments, of which the rst subsegment is small, 2nd large (half the segment), 3rd-9th* small; those of the 8th abdominal are modified by the presence of the caudal horn. The spiracles are creamy-white in colour, placed on the crease dividing the anterior subsegments ; each is oval in outline formed of two lunular-shaped pieces of membrane with the straight edges closely appressed, slightly de- pressed centrally, with a fine, slightly-raised black rim. The prothoracic spiracle is distinctly wider than the abdominal spiracles. A subspiracular, slightly tumid, flange runs from the prothorax to the 8th abdominal segment ; this is made conspicuous by the modification * The last subsegment is very doubtfully distinct from the 8th, it appears to be so more distinctly on some segments than others, 224. BRITISH LEPIDOPTERA. of the front part of the flange on each segment into an oblique red stripe extending across the 1st, 2nd and 3rd subsegments of each abdominal, and by being almost continuous on the thoracic segments; each of these stripes bears, on the abdominal segments, a yellow patch directly below the spiracle, and this carries a stumpy hair, the specialised appearance of which leads one to homologise it with a subspiracular tubercle (iv). The area between the flange and venter is of the same black colour as the dorsum, and with similar yellow spots ; and this characteristic mode of marking is carried almosi entirely-round the venter of abdominal segments 1 and 2. The remainder of the venter is reddish with a dark blackish-grey patch medially on each abdominal segment (either between, orin the position of being between, the prolegs). The prolegs are short and thick, reddish in colour, rather hollow cen- trally, with the outer edge forming a strong flange not very plentifully supplied with red-brown hooks; these are in pairs, alternately long and short, and 33 in number; the anal prolegs are fixed angularly against each other, and are, like the other prolegs, sparingly sprinkled with short blackish hairs. The true legs are also of a reddish colour, each with one strong black curved hook, the joints fringed with short blackish hairs (Tutt. Described from larve from La Grave, August 16th, 1896). We may here note that in Ayles euphorbiae the ovaries in the 9 larva are yellow, the testes of the g larva reddish (Bessels), whilst in the larva ot Sphinx lgustrt both ovaries and testes are white *. VARIATION OF LARVA.—We have already described certain forms of this exceedingly variable larva. At the commencement of the fifth instar, a large number of larve, obtained at Evolena in August, fell into three forms (anfed, p. 221). As they neared maturity much more individual variation was noticeable, and one could safely say that when quite fullfed scarcely any two larve were alike. The commonest form appeared to be that in which the head, mediodorsal line, caudal horn, lateral flange, anal segment, anal prolegs, prolegs and true legs were yellow; the anterior wide (rst + 2nd) subsegment black, carrying the two yellow lateral spots on either side; the six narrow subsegments spotted, but with a yellowish lateral blotch on each side, extending the width of the last five subsegments. A somewhat rare form has this lateral series of yellow or orange-yellow blotches obliterated (or almost so) by the spotting being continued all over the segments. Others again have the black of the rst + 2nd subsegment continued back on the succeeding subsegments with only a few pale dots on the last three subsegments of each segment. One or two have, on the other hand, the black of the rst + 2nd subsegment spotted so much laterally as to almost lose the usual annular, or black-banded, appearance. There is, in all these, great difference in the intensity of the tint of the yellow parts, some of the larvae having quite a deep orange medio- dorsal line, lateral flange, prolegs, etc. The red form, already described (anted, p. 222), appears to me one of the most handsome. A few of these Evolena larve that Chapman brought to England were to note that Rengger, in his Phystologische Untersuchungen uber die thierische Haushaltung der Insecten (1817), has made considerable use of Hyles euphordiae for his anatomical investigations. HYLES EUPHORBIA. 225 markedly aberrant, and more or less darkened to a degree that none exhibited when captured ; it was especially to be noticed that the great yellow blotch across the small subsegments was very small or wanting, in some the small yellow spots were few, in others they crossed the space the blotch usually occupies ; the white or yellow spots on the wide anterior subsegment were creamy or even red, the dorsal and lateral bands reddish, and, when the yellow spots of the small subsegments were wanting, the central hair of these seemed also to be absent or less regularly placed. In one specimen there was no lateral band, no blotch, the dorsal line very narrow and red, the white spots on the rst subsegment small and the dots of the other subsegments very few; in all the examples the black marks on the head were very definite, although these are often wanting in typical larvee in last stadium. Whether this variation was due to their being late specimens, or to starvation in captivity, or, what is more probable, from their not being exposed to the broiling sun which the larve seem to enjoy, is not very easily decided, but all became more or less dark as very few were at the time of capture. Merrifield observes (Zn¢. fec., xii, p. 320) that the larve from the Grisons vary greatly in colour and to a less degree in markings, and tend to gather into three groups: (1) The predominant colour reddish, very much the colour of red vulcanised india-rubber, the most common form. (2) With yellowish- green the prevalent colour. (3) The ground-colour mainly blackish. The conspicuous feature, in which all three agree, is the subdorsal row of large light-coloured spots, varying from white to yellow, usually cream-coloured; all the other markings, except, perhaps, the reddish colour of the dorsal line and head, &c., in most of them, go for nothing at a casual glance. Chaumette gives (Zoo/., 1x., Pp. 3159) the following description of the various forms of the larva found at Lausanne: (1) No triangular patches of yellow or brown along the sides ; the abdomen black, or black with an interrupted ventral line of carrot-colour. (2) The two lateral series of oval shining yellow patches joined, forming a series of large oblong patches ; this is spotted with much larger spots than the common form, whilst in the place of the lateral series of buff triangular patches there is a broad and continuous ferruginous longitudinal line, which is sometimes marked at the incisions by a small patch of red. (3) No triangular — patches of yellow or brown, &c.; not so thickly spotted with yellow along the sides as the others; dorsal line very slender, and, in some individuals, entirely missing, its position being left in black; the oval lateral yellow patches often tinged with pink, especially the lower ones, which are sometimes quite pink ; the head generally retaining the two black patches which the others only have when young ; the abdomen and prolegs generally quite black, and the thoracic legs generally tipped with black, and often entirely of that colour. Buckler thus writes (Larvae, &c., ii., pp. 33-35) of four larvee, which he also figured (Joc. cit., pl. xxiii), all in the last instar, although varying in size: ‘The ground-colour of the smallest was black; the next in size was blackish-green, with a multitude of small bright yellow dots, contrasted with larger spots of yellow tinged with a rosy hue in the centre,” whilst, for the rest, Buckler describes one fullgrown larva, and then mentions the variations of detail in the others, as each preserved its individual points of difference to the last, ‘The fullgrown larva P 226 BRITISH LEPIDOPTERA. measured from 3ins. to 32ins. in length, and was, in proportion, a trifle more slender than the larva of D. gall, though otherwise similar in form, being plump and cylindrical, tapering considerably from the 4th segment to the head, which is the smallest segment, and is rounded in outline, tapering a little also at the two hinder seg- ments, the 12th having a rough, blunt-tipped horn, curving a little backwards ; each segment from the 5th to the rz2th is sub- divided into seven rings by well-defined wrinkles, the front ring being equal in width to three or four of the others. ‘The skin was generally smooth and shining; the anal prolegs larger than the ventral prolegs and of a squarish form; the segments appeared more plump and swelling on the ventral than on the dorsal surface. As to colour, no two individuals were of the same type, the ground- colour of the skin only varying in intensity from a bronze-green to a deeper blackish-bronze. ‘The head was blood-red, the mouth and base of papillae pale yellow, the former margined above and below, and the latter surrounded, with black ; the dorsal stripe was blood- red in colour, widening on the second segment in a curve down either side, suggestive of a plate, but thence continuing of nearly uniform width to the anal flap, which was likewise red. The horn was of the same colour, but glistening, and with the tip black. In these larve the subdorsal region bore a row of very blunt wedge-shaped red marks, widest at the hinder part, and pointing forwards, and a row of large roundish or dumpy pear-shaped bright ochreous-yellow spots slightly tinged above with pink (on the 12th segment of a longer pear-shape, with the stem pointing to the horn) ; below these was another similar row, only paler and irregular in shape from a fold in the skin, these spots, on each broad front ring, being much surrounded with black; below these were a few small white dots, and then the whitish oval spiracle ; the narrower hinder rings of each segment—whether in the red wedges or on the ground-colour—bore transverse rows of thickly-set yellow dots ; the puffed region below the spiracles showed red interruptedly, but without any dots; beneath this was a patch of the dark ground colour sprinkled with white dots; the tips of the ventral and anal prolegs were blood-red ; the anterior legs were orange-ochreous tipped with black. Two striking aberrations occur: (1) The form which may be termed the red variety, from the great quantity of this colour which it possessed, and which had the first or broad ring of each segment of a black ground-colour, and the narrow rings of a bronzy-green ; the wedge shapes of red in the subdorsal region extended along each segment from their greatest breadth at the last ring to the blunt apex close to the broad front ring; the dots ot yellow above and _ whitish below, and the double series of large spots were as described above; all the rings were abruptly interrupted by the inflated and rather tortuous broad subspiracular region coloured red; below this, on each segment, came a pear- shaped patch of bronzy- green dotted with white ; all the rest of the belly and legs were red, but inclin- ing at the segmental divisions to deep ochreous or greenish-ochreous, as the above-mentioned red wedge marks also did at the same place. There were a few yellow dots at the segmental divisions in the subspiracular region; the black plate on the second segment HYLES EUPHORBI. 997 was margined with red; the red head and the dorsal stripe, &c., were as in the other varieties. (2) The black variety had no sub- dorsal wedge marks; the first ring in each segment had a black ground, the others a greenish-black ground, dotted and _ spotted with bright sulphur-yellow above and white below; very little of the spiracular region was inflated, it was coloured crimson-red and Geareous, the red; in the middie gently blendmg with the ochreous at each segmental division; the anterior edge of the second segment was yellow; a large round black spot on the top of each lobe of the crimson head. The anterior half of the anal prolegs was black, the rest crimson; the crimson ‘dorsal stripe quite narrow; the anal flap was black, margined with crimson. Buckler also describes a variety of this larva, brought home in spirits from Cairo, by Jenner-Fust, which he received in May, 1871, and figured. This had the broad ring of each segment be tie eround colour of the other rimgs .of the deepest blackish-olive ; the head, the plate on the second segment, fie aersal stripe, the legs; anal flap, and caudal horn were blood-red. The double series of large spots was creamy-whitish ; the upper rows of small dots pale yellow, the lower rows white; the subdorsal truncated-wedge shapes were of deep ochreous and largely developed ; the inflated subspiracular region, belly and ventral prolegs, of deep ochreous or buff colour, the latter tipped with red ; a pear-shaped blotch of dark olive dotted with white was situated below the subspiracular region on each segment ; ciemamvenion legs ted. Elarrsom notes (m7. FRec., 1%., p. 203) : “The changes in colour that many larve undergo in the final stadium are as follows—The red dorsal stripe turns yellow, then black ; the subdorsal and supraspiracular spots undergoing the same changes in turn. Then the caudal horn, head and legs, become blackened (without, however, turning yellow). In the very black forms, the supraspiracular spots almost cease to exist, and the subdorsal are only visible because of their brighter surface. About seventy larve underwent the above changes, and these must have been quite normal, and not due to disease, for the larve continued to eat most ravenously, and out of about eighty larva, which did not go down at once, only five were lost.” Réaumur notes (AZémoires, 1, pp. 289-291) that, when the larva is young or has just changed its skin, its colours are more delicate than at other periods, and immediately after a moult there is less black, whilst a delicate green tint, with some little yellow, prevails. Later, when the colours aterixed, it 1s blacker; it also has yellow where it will be red, and white where it will be yellow when the larva is more mature, the yellow becoming first tinged with red, and then red, and the white takes a yellow tint and then becomes yellow. There are larve that have only the little dots yellow, all the larger ones being red—either rose-coloured or of some deeper tint. When about to pupate the larve change colour, becoming dirty brown and having only some whitish spots. Weismann says (Studies in the Theory of Descent, pp. 206-207): “In the last stage the dorsal line is sometimes black and sometimes red, or, again, this colour interrupted with black, so that only small red spots mark its course. The head may be entirely red, or this colour mixed with black. On the underside 228 BRITISH LEPIDOPTERA. of the larva, red generally predominates, but, in some specimens, this is replaced by black. The ground-colour is also variable, being generally a shining brownish-black, but sometimes dull coal- black. The shagreen dots are sometimes white and sometimes yellow, and the ‘‘mirrors” of the ringspots are also often yellowish. In many specimens from Kaiserstuhl, the red was unusually vivid, and was not limited to the ordinary places, but occupied also the triangles on the posterior edges of the segments (fig. 44), which are green in the 3rd and 4th stages (fig. 42). ‘This form has also been figured by Hubner. In one individual (fig. 43) the under ringspots were wanting, whilst the upper ones possessed a beautiful | red nucleus, fading away anteriorly and showing the first step in the formation of a complete eyespot.” Caradja’s observation that, in Roumania, the summer larve are of light colour, but those which appear in autumn always extraordinarily dark, is interesting. In opposition to the usually accepted view, the same author makes the noteworthy observation that the lightest larva mostly produced darker, often red-tinted, moths, the darkest always light specimens only. Bartel notes (Pal. Gross-Schmett., 11., p. 80) that, “in Sicily, the larve of this species are of a brighter green colour than in Central Europe. The black colour which, in general, characterises the full- grown larve of the latter locality, disappears almost entirely. The large yellow spots on the sides are filled in with white, and the yellow line over the legs is unicolorous and entirely without admixture of red. In Spain and other localities of southern Europe (also in western Asia and in Algeria) almost entirely bright yellow coloured larvee occur ; the head of these is red, but they produce only the ordinary form of the moth. Larve from the eastern Pyrenees form in their markings a transition from the ordinary D. ewphorbiae larve to those of DY. mzcaea.” Lederer records larve from Amasia and Tokat as being exceptionally pale. Eaton observes that the adolescent larve, exceedingly abundant at Biskra, do not present any variation in colour, only that some have the dorsal line red, others yellow. Sich says that the larva) become somewhat duller when fullfed and at the time that they are wandering about for a place for pupation. DEVELOPMENT OF LARVAL MARKINGS.—/irs¢ instar: The young larvee (Studies in Theory of Descent, pl. v., fig. 37), immediately after hatching, measure 4mm.; they are at first rather light, but, in the course of half-an-hour, they are seen by the naked eye to become of a deep velvety-black ; later, on increasing in size, they again become paler, appearing of a greenish-black, and subsequently blackish-green. On further increasing in size (fig. 38) they are blackish-green, with the horn, head, legs, and a crescent-shaped chitinous plate on the back of the prothorax black. There are also, on the last segment, a double and two single black chitinous plates. Of the later marking of the caterpillar there is scarcely anything present. ‘The spiracles appear as white spots, and, on each segment, there are a number (usually 10) of small warts, each of which emits a single bristle. When the young larve have attained a length of 7mm. they are olive-green, and do not contrast so brilliantly with the green of the LZuphorbia leaves as_ before, neither do they as yet possess any markings. Second instar; The HYLES EUPHORBIZ. 229 first ecdysis occurs after five days, and with this there appears quite suddenly a very complicated pattern. The ground-colour is now a light yellowish-green (fig. 39), and, on each of the 12 seg- ments, near the front border, there is a pure white round spot in the middle of a large black transverse spot. These are designated as the white “mirrors” on black “ ground-areas,’ both together constituting ‘“‘ring-spots,” as distinguished from ‘“‘eye-spots” proper, in which a “nucleus,” the pupil of the eye, is also added. In many, but not in all, specimens, very distinct traces of a subdorsal line can be seen as a light whitish stripe connecting the white spots. The horn, the thoracic legs, prolegs, and some spots on the head are black. The larve remain unaltered till after 4 days, when, having a lenyth of 17mm., the second moult takes place, bringing with it changes quite as great as those which occurred with the first. Zhird instar: The larva now assumes the shagreened ap- pearance which it possesses in the adult stage. Small white warts are arranged in rows from the dorsal to the spiracular line, and again, underneath this line, on the abdominal legs. ‘These dots are not only of value as a character for differentiating Deilephilid from Choerocampid larvee, but they also play a part in the peculiar spot-marking, which will be shown later on. ‘The ground-colour of the larva is now light-green (fig. 40), replaced by black oa certain parts. From the black “ ground-area” of the ring-spots, two black triangies extend towards the posterior borders of the segments, but usually without reaching them. The ring-spots are not essentially changed, although it may be observed that, in most specimens, the shagreen dots under each ring-spot are somewhat larger and stand closer together than in other places. In the following stage they become fused into a second white “mirror,” so that two ring- spots stand one above the other, their black ground-areas meeting. The formation of the second ring-spot sometimes takes place in iiempresent stage (fig. 42). The subdorsal line has now com- pletely vanished, whilst the infraspiracular line appears as a broad stripe above the legs. The horn is yellow with a black point, and the black spots on the head have increased in size. /ourth instar: The third moult, which again occurs after 4 days, is not accompanied by such important changes.. The green ground-colour has now completely disappeared, and is replaced by a dull black. The larve are now, as also in the previous stage, extremely variable. Thus, for example, a triangular patch of the green ground-colour may be retained on the posterior edge of the segments (fig. 41), those specimens which possess this character generally having their mark- ings retarded in development, as shown by the absence of the second “mirror” of the ring-spots. In fig. 41, the shagreen-dots, from which this second mirror is subsequently formed, are distinctly larger than the others, and, on the 11th segment, two of them have already coalesced. ith instar: After another period of four days, the fourth moult takes place. The marking remains the same, but the colours become more vivid, the brick-red of the head, horn, dorsal line and legs changing into a fiery-red. The infraspiracular line, formerly green alternating with yellow, generally becomes resolved into a row of reddish-yellow spots. Ten days later the larva (8°5cm. in length) ceases to feed and prepares for pupation. In this last stage 930 BRITISH LEPIDOPTERA. also there is great variability of colour, but, although each particular character is Subject to fluctuation, the individuals of the same brood show but little variation among themselves.* . . . I cannot assert that a fifth moult occurs in the last 1o days, although I am very doubtful whether this is the case. It is certain, however, that some time before pupation, and whilst the larva is still feeding, the striking colours fade out, and become replaced chiefly by black. The onto- geny of this species is obviously but a very incomplete representation of its phyletic development. This is at once apparent from the large gap between the rst and and stages. It is not possible that a row of ring-spots can have arisen suddenly ; in all probability they have been developed from a subdorsai line which, in ewphorbzae, is now only in- dicated in the second stage by a faint line. ‘This conjecture is raised to a certainty when we call in the aid of the larve of the remaining Deilephilid species (Weismann, Studies in Theory of Descent, pp. 202— 207). Cocoon.—The cocoons are of a very firm texture, spun with strong and coarse silk threads attached to some leaves of spurge above, and with some sand interwoven, and, in each instance, firmly fastened to the side of the pot in which the larve have been placed, and sunk about 3in. below the surface of the sand, so as to be immovable, though the sand was loose. The interior of the cocoons beautifully smooth, with fine silken lining (Buckler). The larve make a hole about tin. deep, “roofing” and “ walling” it with silk, mixed with sand, bits of leaves, etc., but without making a distinct floor. They remain in the cocoons about a week before turning to pupe. In spite of the normal habit of the larva to make its cocoon partially underground, many individuals made up their cocoons on the surface among leaves (when earth was not available), the silk used being dark yellow in tint (Harrison). | When tullfed the larva enters the ground in which it makes a cocoon in which to pupate (Réaumur). Cocoons are sometimes found in nature in Malta, among rubbish on the ground, the larve spinning the materials tightly together (Mathew) ; larve pupate on the surface of the ground either free or in a loose cocoon (Bartel). The larvee pupate under moss, &c., placed in the breeding-cage, and choose the darkest places that can be found (Sich). Thirteen larvee formed loose cocoons in sand (Fry). .The larve pupate in the sand, forming a loose case of earth around them (Curtis). ‘The cocoons are found just below the surface of the ground (Johnson). Pupa.—The pupe of yles euphorbiae and Celerio gallit are extremely similar. As compared with our other British species, they agree with Zheretra porcellus and Eumorpha elpenor, in general outline and in the anterior position of the labrum, more than with any others. They are, however, less specialised than those of T.. porcellus, £. elpenor, &c., in so far that the latter has an appreciable keel to the maxilla, whilst in “7. euphorbiae the head extremity of the pupa is fairly rounded on all aspects, and, in fact, except that the *Upon this fact obviously depends the statement of that extremely accurate observer Roesel, that the larva of ewphorbiae is but very slightly variable (Znsekter- belustigungen, iii., p. 36). I formerly held the same opinion, till I convinced myself that this species is very constant in some localities but very variable in others. It appears that local influences make the larva variable (Weismann). HYLES EUPHORBI&. 931 labrum is definitely anterior, the maxilla has undergone no further development. Nor are there any rough ridges on the abdominal seg- ments as in the pupa of £. e/fenor. In its general outline, the pupa is an ordinary obtect pupa, slightly flattened from back to front, and carrying its full thickness right up to the prothorax, and, with slight diminution, to the 7th abdominal segment, the 6th and ath do, indeed, diminish appreciably, but the three following segments diminish in a rapid cone. There is hardly any curvature in the pupa, it might be called straight. The anterior extremity is nearer the venter than the dorsum, the rounding being chiefly dorsal and the anal spike is on the dorsal edge of the otherwise somewhat truncate extremity. The measurements of an individual selected at random are: ANTERO- POSTERIOR DIAMETER AT Fe ASUREMENES AE FROM HEAD TRANSVERSE rae (LABRUM) AT |DIAMETER AT Mid prothorax .. a a ae a 30mm. 8-omm. | 8omm, Front mesothorax ie li ae oh 55 gO ;, 100 ,, Hind margin mesothorax... ae ae Ilo ,, 10°0 ,, 100 ,, End of Ist leg aie ae ore oie 8 13°0 ” End of antenna A is oe I4O ,, Widest part 4th abdominal .. 56 she 20°0 ;, IIO ,, ONO 5g End of maxillz.. a ae BF 210 ,, Widest part 5th agonal tee ate 4 24°0 ,, 10°0 ,, 9°5 >.

The first spiracular opening is a narrow slit directed forwards. The posterior lip being comparatively wide and lying flat, passes forward over the anterior one; it is dark in colour. ‘The other spiracles are dark, an oval depression with the transverse opening axially surrounded by a fine raised lip. The prolegs are depressions, centrally smoother, with radial impressed lines. The cicatrix of horn on dorsum of 8th abdominal is slightly raised with the sculpturing radiating from it in fine ridges, just behind it is a depression, which looks like, and doubtless is, the result of the pressure of the base of the larval horn, when depressed backwards on the pupal skin, just before the pupal moult, not recovered from before the hardening of the pupal cuticle. A suture is visible down the prothorax, and a false one down the mesothorax, ze, there is a dorsal line or ridge so placed as to give a white line. The sides of the anal groove are full, but do not amount to bosses or tubercles, the anal spike is roughly wrinkled dorsally, ventrally it is longitudinally wrinkled for the basal, smooth for the terminal, half. At the wing-bases some speci- mens have small brown points raised above the general surface, generally in one or more groups of two each; sometimes similar points occur, symmetrically on the wings. Others are quite without them. There are no other special marks, tubercles, &c., even the * A large specimen may reach 50mm, when stretched out (Chapman). 939 BRITISH LEPIDOPTERA. labrum and angles of the epicranium are quite flat, just marked out and no more. The surface sculpturing is of labyrinthine wrinkling over the head, thorax and appendages, becoming, on the abdominal dorsum, an arrangement of pits. Over the head and pro- and mesothorax, the aspect is much that of cerebral convolutions, the summits being pale, the sulci dark: over the appendages the sulci are more nearly transverse, and fairly regular over the antenne. Poulton’s line is well-marked, but the neuration, which looks obvious at a rough glance, is marked only by a longitudinal arrangement of some of the sulci of the wrinkling. On the abdominal segments the pits tend to run together into sulci, and this is marked in certain transverse lines, apparently indicating sub-segmentation, but varying in clearness to a great degree in different specimens. ‘Two lines are usually seen in each segment, the first 2and the znd # from the anterior margin of the segment, sometimes presenting two distinct black lines; on the znd and 3rd abdominals the posterior element, instead of being only 4+ of the segment, or, being really 4 of the segment, has behind it a very definite similar element that might be intersegmental membrane fixed. The 7th abdominal segment has a broad rounded posterior margin, as if the 8th segment, being consider- ably smaller, had been well telescoped into it. The one structural point by which it is clearly separabie from the pupa of C. gad/a is the sculpturing of the prespiracular areas of the 5th and 6th abdominal seg- ments; on segment 5 this area is not punctured, but the ridges rise into a series of sharp edges, transverse to the segment, and, here, the ordinary rule of colouring is reversed, the sharp edges being dark and the rest of the area paler (everywhere else the ridges are rounded). On abdominal segment 6, the ordinary sculpture prevails; there is, per- haps, one little ridge close to the spiracle. Another point of difference with C. gal/iz is in colouring, but this is so much a matter of degree that one may doubt its holding good in all cases. The colour is a pale terra-cotta, varied with more or less black, which is sometimes confined to the sulci and pits, but sometimes invades the general surface, and a more or less ruddy tone, or a brown is sometimes evident on the abdominal surface. | Usually, the wings are palest, occasionally they are darkest, and similar variations prevent any general description as to the distribution of colour. ‘The character of the general wrinkling is much smoother in /. ewphorbiae, as if rubbed down and polished, the sulci being very narrow in comparison (see anted, pp. 188-189, ‘ Pupa of C. gall”). ‘To distinguish the two pupee (if together for comparison) it suffices to pass the finger over the mesothorax, when C. galdit gives a sensation of roughness in comparison with the polish of 4. euphorbiae (Chapman). Long and slender, very like that of a Sphingid (sezs. s¢ric¢.) in general outline, except for the maxillary protuberance. Head, wings and appendages of a dull ochreous-grey but with a slight greenish tinge ; the skin rugose; the abdominal segments transversely subdivided, brown, the 7th and following segments being darker as also is the smooth skin of the incisions between 4-5, 5-6 and 6-7 ; a dark medio- dorsal shade runs down the centre of abdominal segments ; on ventral surface of the 5th, 6th and 7th abdominals a narrow median longi- tudinal fissure, and traces of the position of the larval prolegs ; the > cremastral horn moderately long, black-tipped, and bluntly bifid.

The genital organs conspicuous on the 8th abdominal segment (Tutt. Described September 2rst, 1899). Poulton figures and describes (£x¢. Morph. Lep. Pupa, p. 205, pl. xx., figs. 22-23) the terminal abdominal segments of the pupa of this species. Fig. 22 represents the last three segments of a male pupa, seen from the right side, natural size. The rudimentary spiracle and the scar of the caudal horn are seen on the 8th abdominal segment. The horizontal furrow which divides the roth abdominal into a dorsal (rostral) and ventral (anal) part is unusually distinct. The division is rendered especially apparent because the dorsal part extends further anteriorly than the ventral, so that the oth abdominal is narrow in front of the former and becomes suddenly broader in front of the latter. Fig. 23 (x 26) shows the median ventral area of the 9th and adjacent parts of the 8th and roth abdominal segments, showing the g organ and the sculpture of the surface very distinctly. Thedg organ is somewhat asymmetrical. The two tubercles in front of it are probably an individual peculiarity. Buckler writes: “‘ The pupa is rgins. in length, Jin. in diameter, taper- ing a little from the thorax to the frontal extremity, where it is rather smooth ; the wing-cases pressed close to the body; the abdo- Minaleenines sin tolerable) nelief); the outline tapered a little near the anal tip, which ends in a broad, flattish, downwards- curved spike, pointed at its extremity.

The spiracles black.” COMPARISON OF PUP OF CELERIO GALLI] AND HYLES EUPHORBIE.— Taking the examples of C. gal/zz before me, which may or may not be typical, it is very difficult to find any definite distinction between the pupee of C. gallii and HY. euphorbiae. ‘The one definite point is that the peculiar sculpturing in front of the spiracles which, in the pupa of Z. euphorbiae, is practically confined to abdominal segment 5, in that of C. valli affects also abdominal segment 6 and quite appreciably segment 7. It is on a more definitely marked off separate area, and is slightly different in character, the ridges being rather closer and in more con- tinuous lines, and with a more abundant supply of paler colouring, z.e., more ruddy, less black. The general colouring of the pupa is darker 234 BRITISH LEPIDOPTERA. and redder (on the average). The front of A. euphorbtae is com- paratively smooth and rounded, with no tendency to spines or tubercles. The pupa of C. ga//iz may be about as smooth, but there are often distinct frontal spines (epiclypeal) beside the labrum, and _ fainter ones on the summit of the head. The summits of the wrinklings (cerebral convolutions) vary in height, or appear to do so, and the pupa feels rougher, apparently this is due to the wrinkles in the pupa of ZH. euphorbtae having flat tops and very narrow perpendicular-sided valleys between, whilst in that of C. gad/iz the valleys are wider and more open and the ridges consequently narrower. On the abdominal segments, pitting does not so soon or so completely replace wrinkling, so that, on the 4th abdominal segment, it 1s doubtful whether it would be easier to describe the sculpturing in terms of wrinkling or pitting. In the described specimen of A. euphorbiae the antenna reached further than the first leg. This is not always the case but sometimes the antenna reaches even further than in that specimen. Apparently the antenna tends to pass the leg more frequently and fully in C. gall than in A. euphorbiae. The anal spine varies as in Z&. euphorbiae, 1. some being very fine and sharp, in others short and blunt, some present distinct evidence of a bifid tip, but A. euphorbiae does so also. In size, the pupa of C. gadllii averages somewhat smaller. It is also possible that C. gaddz is a little more flattened dorsally and tapers a little more gradually behind, but, if so, the difference is very slight in either case, and individuals vary more than the average difference covers (Chapman). DuRATION OF PUPAL STAGE.—It seems almost impossible to accept Mazzola’s statement, referred to by Treitschke (Dze Schmett., X., Pp. 131) that he had an example that emerged after bempug years in the pupal stage, but our own records show that the pupal stage may be anything from 15 days to 15 months. Curtis states (on Raddon’s authority) that the pupal stage sometimes extends to a second year, and hints that the shifting of the sand on coast sandhills covers up pupe for a great length of time, that they lie hidden and alive, and that the moths do not emerge until brought to light and life by the influence of the elements!! Mathew’s tabulation (andéed, p. 216), also, is most interesting from this standpoint. Of four larve taken in Capri, in May, 1866, and that pupated at about the same time, one was only in the pupal stage about 3 weeks, the imago emerging in June, the others at long-distant intervals, the last not appearing until October (White) ; at Munich some emerge in late autumn of the year of pupation, others not till after a second winter or even later (Kranz) ; of six larve taken at Ingolstadt on August 2nd, 1892, four pupated August 6th-8th, and one imago emerged August zoth, having been only 12 days in the pupal stage (Strohmayer, Soc. £nt., vit.. p. 142). The pupal stage in Sicily, in the summer, usually lasts only three weeks (Bartel) ; in Upper Austria the pupal period varies, in 1897 an imago was bred from a pupa 19 days old, but sometimes the pupal stage goes over two winters (Hims}). In the Bilbao district, larve that pupate in August frequently produce imagines in October (Rossler). STRIDULATION OF PUPA.—Pupz moistened, and when _ placed in water heard to hiss, sound repeated several times, and resembled that of a snake (Weir, £7/., xiil., p. 218) HYLES EUPHORBIA. 2a Forcinc pup#&.—This pupa lends itself readily to the forcing process and imagines can thus be produced throughout the winter ; 20 pup placed in incubator with evaporating’ water, on January roth, 1884, and subjected to a temperature fluctuating between 27° C and 30°C all emerged between January 28th and February arst, 1884 (Weismann); three pupz placed in forcing-box October 21st, 1872, placed box at first on iron plate of a kitchen stove over boiler where the situation was warm through the greater part of the night and quite het by day, when the bottom of the box was elevated two inches above the hot plate by the aid of two strips of wood on which the box rested ; here they were damped with lukewarm water twice a day. On the 23rd of November a fine and perfect moth came from the earliest pupa, but after that my efforts were baffled ; the two remaining pupz continued lively but the moths would not appear. I moved the box to a place before my sitting-room fire, but without effect, and, at iast, I came to the conclusion that I ought not to have begun the forcing till the weather had become dry and frosty, and that then the heat would have had due effect, but as it was, the great humidity of the atmosphere had prevented this, and sufficient heat had not reached the pupz to develop the imago in them at once. After continuing my forcing till the end of December, I put the pupe aside to wait for summer, but before that time came they had died (Buckler). We have more than once placed pupz of this species on moss in flower-pots on a kitchen mantel-piece in January and moistened the moss slightly every day ; few of the pupz resist this treatment more than 5-6 weeks before giving up their imagines. Fooppiants.—Luphorbia, | Galium|* (Linné), Luphorbia cyparissias (John), Z. amygdaloides (A. H. Jones), Euphorbia peplus, E. portlandica (Buckler), £. paralias (Harrison), £. esula (Glitz), Zithymalus helioscopius, TZ. gerardiana, Fuchsia (Bartel), £. prscatoria (Long- staff), £. guyoniana (Eaton), £. dendroides, E. pinea (Galvagni), E. wulfenit (Garbowski), Euphorbia exigua, preferring slightly withered leaves (Sich), particularly fond of the milky juice of the Euphorbia (White), vine leaves (Berthelin, Bull. Soc. Fut. Fr. 1881, p. clvil), [oak (Scheffler) |. There is some suggestion of “ gastric educa- tion” in the species, ¢.g., Garbowski notes larve as eating Euphorbia cyparisstas but refusing £. peplus and other Euphorbiaceae. Robson — records ( Young JNat., il., p. 310) &. peplus being preferred to Z£. amygdalndes and E. esula. He adds (éeste Millar) that the larve will eat dandelion, on which, however, they do not thrive. Unterberger fed the larve on lettuce (///. Zeits. fiir Ent., ii1., p. 232). Laubenheimer has (Ler. Oberhess. Ges., vi., p. 82 [1857] ) a short note on the foodplant of this species which, he says, is rare at Giessen on account of the absence of its natural foodplant, although occasional larve have been met with on the species of Zuphorbia growing in the Botanical Gardens. He asserts that no other foodplants but species of Luphorbia are known, and Esper has expressly mentioned that he repeatedly tried to induce them to take substitutes, but failed; Laubenheimer thinks it, * Linné’s references (see avtea, p. 202) show that he had mixed up euphorbiae and gadilizt under the former name. Undoubtedly this foodplant ‘* Galzwm”’ resulted from referring De Geer’s species ( galliz) to euphorbiae. 236 BRITISH LEPIDOPTERA. therefore, worth recording that, on August 31st, 1856, he found eight nearly fullgrown larve on Polygonum aviculare near the Badenburg, and fed them up successfully upon this plant, which they seemed to prefer to the Luphorbia peplus that he also offered them. PaRASITES.—Wicrogaster nigriventris, Nees (Rodani). Bartel notes (Pal. Gross-Schmett., i\., p. 81) that the larve are frequently attacked by hymenopterous and dipterous parasites. The larve are also sometimes affected by 7ilarzae. : HYLES EUPHORBIZ AS A BRITISH INSECT.—Moses Harris, in the Aurelian, i 1778, introduced this species as British, on the strength of a larva taken on marshy ground at Barnscray, near Crayford in Kent. He figured the pupa and imago (/oc. cit, pl. 44) from Belisle, in France, with the larva of C. gall, presumably also from a foreign example, as the larva he obtained at Barnscray refused to eat and died a day or two after capture. His descrip- tion of the larva that he captured is certainly not thatmauss euphorbiae. Donovan gives (vit. Jns., ill., p. 51, pl. gi-g2) ex- cellent figures of the imago and larva of the species, and notes that these are not from British examples. He further observes that Drury had given a figure of the species among his rare insects, but as a native of a foreign country. Donovan himself bases the British authenticity of HY. euphorbtae on a damaged imago stated to have been taken at Bath, and four larve taken in Devonshire, in 1793, by Curtis: Haworth simply writes’ (Zep. 6777. p. 61): “Wales Devonia. Larva on Luphorbia,’ but in Trans. Ent. Soc. Lond., 1807, pl. iv, he figures a specimen of HY. euwphorbiae under the name of Sphinx gala. Curtis (rit. Lut., v., fo. 3), in 1823, and Stephens (Lllus., 1.,P. 125), in 1828, give details of Raddon’s captures in Devon, Raddon himself, in 1834, publishing (Lut. Mag., i1., pp. 535-536) the particulars of obtaining this species. He observes that, in the autumn of 1806, he visited north Devon, and, whilst at the village of Instow (opposite Appledore), the first larva was brought him by a fisherman. ‘This was forwarded to Fuesli, who considered it to be the larva of Sphinx koechlint (=livornica). Between 1806 and 1819 the larvee were very plentiful, and this was especially the case in 1814, when, after a day’s search in which only fullfed larve were taken, Raddon gathered an armful of spurge for food, placed it in water on his arrival home, and, in the morning, found the plants covered with not less than a hundred minute larve only a day or two old. Fuesli, Leach and others, to whom pupe were given, appear not to have been very successful in getting imagines from them. A collector named Cocks is noted by Raddon as getting a fullfed larva on October 3rd, 1834*, which changed at once to a pupa that was sent on to Raddon, ‘The species from this date apparently ceased to have any British habitat. Isolated records of possible immigrant or escaped imagines occur occasionally until 1872, when two imagines were exhibited at the meeting of the Entomological Society of London on September 17th, 1873, one a remarkable aberration, said to have been bred from near Harwich from “ This. was one of ‘the. C. gallit years (see anted,, Dp: . 195), and this particular larva may possibly have been referable to this species. HYLES EUPHORBIA, Oo larve taken with several others in June, 1872, by a man named Durand (2772, vil. p, 46, 1X., p. 263), but, besides the great im- probability of June larve being found in this country, other circum- stances led to disbelief in the British origin of these examples. In 1889 and 1890 St. John published (£77, xxiil., pp. 18, 319) a somewhat vague account of the capture of larve in Cornwall, supplemented, and certain inaccuracies corrected, later by Fry*, the captor, who observes (Joc. cit., XXV1., pp. 315-316) that he took, in August, 1889, 18 or 19 larve about two miles trom Newquay in Cornwall, and that of these 5 or 6 died, 13 formed cocoons, of which one was given to a schoolfellow, and 12 to St. John to rear, three of these were reported dead, nine were said to have emerged, of which one went to Hanbury’s collection, three to St. John’s collection, and five were at the time in Fry’s collection. With the exception of this record, there has been no real evidence of the species being sedentary in these islands for more than half a century, and with the exception of the larva found by Cocks in 1834, for above threequarters of a century. Hapirs.—The imagines appear to be strictly crepuscular in their flight, feeding on the wing from about 6.30 p.m. to 9.15 p.m., settling down before 10 p.m., clinging firmly to their resting-place, and usually remaining in the same position all night. The males poise themselves on the wing, sometimes inaking use of one or two legs to steady themselves whilst hovering at the flowers, although, usually, the legs hang straight down. When the tongue is inserted in a flower it is often bent at almost a right angle, being nearly straight for the first half of its length and then taking a sudden bend downwards to the flower, the thorax of the moth being nearly always above and over the top of the flower and nearly perpendicular to it. A moth will sometimes remain at the same flower for 2 or 3 minutes. Whilst hovering, the humming of the wings is distinctly audible, and if, at this time, a moth be observed in profile with the base of the nearer pair of wings on the same level as the eye of the spectator, the underside of the wings alone can be observed as though the wings, while vibrating, only passed through an arc_of 45° on either side of the per- pendicular. The females appear to fly but little compared with the males. ‘The imagines are noted as living in confinement from ro—14 days. ‘There seems to be no fixed time at which they emerge—wings of one expanded and dry by 8.15 p.m., another 10.30 DMs soo others) before) S) am, one before 6 am, (Sich). Their general habit, in nature, is to fly at dusk at flowers—at verbenas (Barrett), at Saponaria officinalis (Jager), prefer well-scented flowers especially Echzwm and Phlox (Bartel)—although Ruhl notes that they fly whilst it is still ight and continue to do so for some half-hour, until dusk, at Biedenkopf, from about July 7th-26th. That occasional wanderers should be taken in Britain is not at all surprising, for Mathew says (zz /it¢t.) that one was brought to him by a blue-jacket, * St. John’s statement ve these does not agree with that of Fry.

He states that the imagines are evi- dently on the move for a considerable time during the night for he has seen them flying to the electric light from soon after sunset until past midnight, whilst by day, in Malta, they may be seen occasionally resting on walls and posts, but most of them probably hide under stones in the stone-walls; very abundant at light at Aix-les-Bains, in July, 1896 (Agassiz), common at electric light at Davos-Platz, &c. (Sellon), at electric light at Berne, June 21st, 1893 (Huiltbold), also in August from 1893-1895 at Zurich (Nagel), at electric light, July 3rd- 4th, 1898, at Aigle, from 9.15 p.m.-I0.20 p.m. (larve occurring in all stages at same time in the district) (Lowe), also at Zermatt, from August 15th-19th, 1898 (Jones), Steinert says that 7. ewphorbiae (like y/lowcus pinastrit, Eumorpha elpenor and Theretra porcellus) sometimes comes to sugar (/7is, v., Pp. 397). Hasitar.—Much doubt still exists as to whether this species has ever been really indigenous in Britain. Raddon, as we have already noted, records (Zz. Mag., 1., pp. 535-536) that, from 1806-1819, he took many larve on the sandhills at Braunton and Appledore, which pupated in due course, and imagines from which are to be found in British cabinets, whilst Fry has stated: that, in August, 1889, he took 18 or 19 larve in.a little sandy bay at the foot of the cliff, about 2 miles away from Newquay, in Cornwall (£u¢., xxvi., pp. 315-316). More evidence is required as to the iarve reported as taken on the coast near Harwich in June, 1872 (£7, vil., p. 46; ix., p. 263). . The species has no other standing in the British fauna, except for odd examples taken here and there in different parts of the country, evident wanderers from the continent or escapes from confinement * (hundreds of imagines have been for three-quarters of a century annually reared trom pupz in Britain), and which have no real bearing on the scientific aspects of ‘‘habitat” or “ distribution.” Abroad, where the species sometimes swarms, its habitats are ex- ceedingly varied. From the sea-level on either side of the Medi- terranean coast, and the shores of the Atlantic as far north as Brittany, Holland and Denmark, the species spreads inland, being particularly abundant in warm valleys of the Pyrenees and the Alps of central Europe to a considerable elevation. It extends to the east well into Asia, occurring on the arid sandy steppes of the Ural district, Persia, and ‘Turkestan, whilst, in the Kouldja district, it is said to be abundant in gardens throughout the whole of the summer. Harrison says that, on the coast sandhills of Brittany (e.g., at Le Poldu’, it is exceedingly common, whilst Oberthtir notes that in La Manche, Ille-et-Vilaine, and Codtes-du-Nord the species is abundant in, but never found outside of, the maritime zone, abounding in some places on the sandhills quite close to the sea, but it also goes up the rivers, e.g., the banks of the Loire between Blois and Langés * See Lunt. Rec., xv., p. 67. We ourselves have frequently set free imagines of rare species, reared from foreign pupz for which we had no further use. Two living examples of 7/7. euphorbiae have come into our own hands; we have no doubt that these were ‘ escapes.” HYLES EUPHORBIA. 239 (Réaumur). In the Netherlands and Belgium it also extends inland along the rivers (Snellen). In the most southern parts of its range, é.¢., on the dunes to the west and south of Biskra, it is sometimes exceedingly abundant (Eaton), it also abounds on ‘the almost bare slopes of the rocky island of Capri (White), also along the shores of the Bilbao river in Spain (Bell). On the dry sloping banks of the alpine valleys branching out of the Rhine valley, the valleys of Dauphiny, Savoy, the Tyrol, the Caucasus, and the eastern Himalayas it is sometimes very common. Mathew found the larve abundantly on the seashore below the celebrated Bulair Lines, also in woods near the coast of the Sea of Marmora.. Walker notes that the species is quite common on the ‘‘neutral ground” at Gibraltar, and in all the cork woods of the district, whilst Mathew says it occurs also on the coast sandhills between Gibraltar and Algeciras. TIME OF APPEAKANCE.—The emergence of the imagines appears to be very irregular. Normally the moths emerge from pupz of the previous year in June and July in the more northern part of its range, and only occasionally in the autumn from pupz of the year, so that sometimes from the same batch (the larve reared under identical conditions) one or two examples will emerge about three weeks after attaining the pupal stage, the remainder coming out the following year at irregular periods from June to August. In the southern part of its range the species appears to be continuously-brooded, imagines appearing in March-April, June, August and October-Novem- ber, although irregularities in the various broods make it probable that one might obtain imagines (and larve) at any time between March and November in a state of nature, but, even in the warmest parts of its area, the two or three winter months—December to February— appear to be passed in the pupal state. Thus we have imagines in March, April and May at Malta, again in July, yet again in August, September and October, in April at Biskra, in April in the Sierra-de-Chiclana, in July at Albarracin, and possibly there is another emergence in many parts of Spain in September. The main emergences appear to be in June and September in the Bilbao river district (Bell), and in May and September at Gibraltar (Walker). The imagines also appear by the end of April in Turkestan, and in Asia Minor the species is everywhere common in May, ‘and again from the end of July to the middle of August. Along the Mediterranean littoral it is reported as occurring from April to November, but, in the more northern lowlands, there appears to be a main emergence in May-June, and a partial second-brood in July-August, with a long pupal period through the winter. The species is recorded as appearing from May to the middle of November, everywhere very commonly, in Rou- mania (Caradja), and imagines are bred in August from July larve at Gallipoli (Mathew), from May until the end September at Eperies (Husz), whilst at Budapest the appearances are given as mid-April, mid-May, and again mid-June to August (¢es/e Bartel) ; in Alsace from May to Sep- tember (Peyerimhoff), and in the Haute-Garonne almost everywhere in May-June and August-September (Caradja). The following records also suggest double- or partial double-broods—June and September (rare) at Eutin, June and September in the Crefeld district, May and July at Halle (often in very great abundance), May-June and August- 240 BRITISH LEPIDOPTERA. September at Leipzig, in Thuringia, and in Silesia, where it is common, May-June and rarely in autumn at Baden, June and Septem- ber at Wiesbaden, May-June and rarely in autumn in Switzerland, May and July at Fiinfkirchen, July and September, in Tuscany (one suspects also a spring brood), July to September near Florence, June and August in the Loire-Inférieure. It is remarkable that few of the Italian dates are given earlier than June and July—at the end of May, and again in July and August about Rome—but our knowledge of the Italian lepidoptera is most unsatisfactory, and the species may be generally double- or even continuously-brooded in the warmer parts. In the mountains at a moderate elevation the imagines do not emerge until July-August—July 1st-r5th in the Oéetzthal (von Gumppenberg), August 15th-r9th at Zermatt (Jones), July 28th, 1899, almost at summit of the Simplon Pass (Edwards)—here, too, the species is single-brooded as it is also in its more northern and western localities, the west coast of France, Belgium, Nether- lands, the north coast of Germany and the Baltic districts. Other dates given are—middle of May at Teheran, May at Brussa, and the Kouldja district, May and June in the Ural district, end of May at Sarepta, end of July at Noworossiisk on the Black Sea, July and August at Aix-les-Bains, mid-September in Trans- sylvania, in July at Bergun, Simplon, Macugnaga, valleys of the Upper Inn, Bucovina, and most mountain districts. We also have June, common, at Brunswick, May-June at Augsburg and Frankfort-on-Main, July-August at Ulm, August at Bremen. Fritsch gives dates from May troth-July 25th for Austro-Hungary, and only a few isolated autumnal ones. Réaumur notes it at the commencement of July on the banks of the Loire, whilst Harrison records it in June-July on the Brittany coast at Le Poldu, although three imagines emerged September, 1897, from August pupe of the year. Occasionally mountain races gives an odd autumnal example in confinement, ¢.g., imagines occur in the Val d’Herens in June-July, but Chapman reared one, from an Evolena larva, on September 23rd, 1899, after being only 18 days in the pupal stage. There are numberless records of these occasional autumnal emergences in confinement; thus Sich bred ima- gines from continental pupe from July 8th-21st, 1901, and from an egg laid by one of these he obtained another imago on October 7th of the same year. Records like May 16th, 1901, at Malta (Fletcher), early August (from summer pup) at Malta (de la Garde), only help to prove the continuous-broodedness of the species here. Of actual dates of emergence or capture, besides those already noted, we have few. These are July gth, 1860, at Alderney (Walker), May 5th-July 24th, 1890, from Newquay pup (St. John), June 21st, 1893, at light at Berne (Hiltbold), July 3rd-4th, 1898, at light, at Aigle, larve of all sizes occurring in the district at the same time (Lowe), August r5th-19th, 189%, at Zermatt (Jones), a large 2 July 28th, 1899, almost at summit of the Simplon Pass on the Italian side (Edwards), July 24th, 1900, in the Statzer-Thal (Galvagni).

(2) A fullfed larva at Formby on grass, August, 1850 (Gregson, Zvol., 2298). (3) At Taunton, a day or two before October 15th, 1857 (Rawlinson, &. W.

(6) Two imagines, one a remarkable aberration, exhibited by Higgins, September 17th, 1873, at the meeting of the Ent.

We have already suggested (anted, p. 140) that the Eumorphids in their wider relationships appear to fall into two sections, Phzlampel- mma and Eumorphina. It is quite evident that, unless we retain these names, these divisions are really of subfamily value, and, if we may extend the groupings suggested (anfed, vol. iii., pp. 365- 367), it is clear that the Huwmorphidae, in the widest sense, may include the Sesznae, Philampelinae, Eumorphinae, and possibly other groups, of which we, at present, are much too ignorant to formulate even a guess. At any rate, for the purposes of this work, we have now to consider the FPAzlampelina section, which would include the Darapsids, Nephelids, Philampelids, Pachyliids, Acosmerygids, Daphnids, &c. The Nephelids are apparently Eumorphid, but exhibit many very Sesiid characters, whilst the Darapsids are possibly more generalised than the Sesiids and Nephelids, and were given off from the main Eumorphid stem below either of these groups. The Darapsid genera, Darapsa and Gurelca, have unspecialised pupa, and yet are distinctly Eumorphine, so that the suggestion at once arises that the primitive Eumorphid had not only primitive larve (anted, vol. i1., p. 365), but may, without violence, be assumed to have had primitive pupe, so that the Eumorphids may be 244 BRITISH LEPIDOPTERA. looked upon as the main Sphingid stem, with Hemarids, Sesiids, and even the Sphingids and Amorphids as branches, that is, giving the Sphingids a monophyletic instead of diphy- letic grouping, although our further work shows that Bacot’s suggested grouping (anfed, vol. i1., pp. 365-366) has much in its support, and, unless one is prepared to grant a diphyletic origin to the oblique-striped larve— Vilia pe 188 (1856); Butl., ‘Trans.

The genus Daphnis is characterised ( Verzeichniss, p. 134) by Hubner as follows : Forewings a particularly beautiful green, with softly variegated markings — Daphnis megeacus, Ab. feacus, Cram.), D. hippothous, Cram., D. neriz, Linn. In 1835, Stephens, in the appendix to vol. iv of his //ustrations, Paes places 72727 im Daphnis ; im' 1837, Curtis figured merz (Bri. wa xiv tol. 626), and declared it to be the type of Hubner’s genus, and diagnosed it as tollows : Antennae inserted towards the base of the head and close to the eyes slightly attenuated at the base and apex, which latter is hooked, being terminated by a slender setaceous joint somewhat pectinated with scales, rather stout in the male, and transversely striated and fringed with hairs (fig. 1, ¢, portions of the under- side and apex); slender and simply clothed with scales externally in the ¢. Maxiliae not more than half the length of the animal, but very spiral (fig. 3). Labial palpi curved upwards, pressed close te the head and a little keeled (fig. 4), densely clothed with scales, rather long, slender, and triarticulate, basal joint curved and clavate, 2nd as long, more elliptical, 3rd very small and nearly globose (fig. 4a). Head trigonate ; eyes very large, hemispherical, and prominent ; ocelli, none. Zhorax not broader than the abdomen, which is conical. Wings deflexed in repose ; superior lanceolate, the posterior angle obtuse ; inferior small, ovate, the apex a little pointed, the anal angle slightly lobed. Zegs very strong, thighs short, tibiz densely clothed with scales, anterior with a large internal spine, intermediate with two strong unequal spurs, horny and acute at the apex, in the hinder there is a pair also a little above the apex, one spur in each being very long (fig. 8) ; tarsi 5-jointed, spinal beneath, hinder pair longer than the antennz, basal joint exceedingly long, claws and pulvilli small. Zarvae with 6 pectoral, 8 abdominal, and 2 anal feet, the tail short and incurved—Daphnis nerii (type of the genus). Curtis further notes (loc. cit.) that “ Daphnis nerii is closely allied to the true Sphinges, and whether it be right to make a genus of it may be questionable; there are, however, several exotic species “that will group well with it; the caterpillar has a different character 248 BRITISH LEPIDOPTERA. from Sphinx (pl. 195) the spiral maxillee are very much shorter, and the inferior wings are somewhat lobed, as in Dezlephila.” In 1840, Westwood followed Curtis in selecting (Generic Synopsis, p. 89) nerti as the type of Dafhnis and diagnosed it as: Wings entire, acute, posterior slightly lobed ; spiral tongue long ; antennze and labial palpi slender : caterpillar with the neck retractile—weriz, L. All our better informed authorities, Hubner, Stephens, Curtis, Westwood, Moore, &c., appear to have been agreed on the very isolated position of Daphnis nerit among the Palearctic Eumorphids, and even Staudinger in the 3rd ed. of his Catalog, p. 100, isolates it. trom) tiem. It is certainly far removed. from the Hip- potionids and Eumorphids (sews. strict.) with the species of which it has been united, even in the same genus, by such authors as Stainton, Meyrick, Barrett, Q&c. So clearly marked is this distinction, that one feels no-hesitation in removing it from the Chcerocampid, and placing it on the Philampelid, side of the Eumorphid phylum, but two great difficulties occur in dealing with the genus (as also with the tribe in which we place it): (1) Our entire ignorance of the larval ontogeny of typical species of Daphunis. (2) Our ignorance of the life-histories of the species supposed, on superficial imaginal characters, to be related to Daphnis nerit. Ot the detailed structure of the egg we know nothing. ‘The pictures of the adult larva show a very characteristic difference from the larvee of any of the groups described by Weismann (azfed, pp. 141-142), for the single pair of well-developed twin ocellated spots is placed on the side of the metathorax although developed from the subdorsal line, as is the case in the Eumorphids already considered, the rest of the subdorsal (on the abdominal segments) running as an unbroken line to the caudal horn. Thus, it exhibits three peculiarities: (1 and 2) Peculiarities in the position and character of the ocellated spot, and (3) A peculiarity in the maintenance of the subdorsal line, neither point being touched on by Weismann. ‘The pupa is characteristically Eumorphid, of the specialised type seen also in Hippotion celerio and Panacra vigil, whilst the imago, in its markings, is quite swz generis, and very unlike those best known to us and exemplified by the species of the genera Lumorpha, Theretra, Hippotion, Phryxus, Hyles and Celerto. In this respect it approaches much more closely to the Acosmerygids and Philampelids with which we trace a close alliance. Whether the larval and pupal characteristics of Daphnis nerd are common to other species that must be referred to the Daphnid line of development we do not know, except that the larva of D. Hypothous is figured as being very similar to that of JD. neriz, nor have we been able to obtain from the voluminous writings on the Sphingids any details that help us in our work. Whether, therefore, the characters noted are generic or tribal we cannot even hazard a guess, although we surmise that they will prove to be the latter, z.¢, we shall expectwie adult Daphnid larve to have metathoracic twin ocellated spots, and the pupe to be highly specialised with frontal or dorsal labrum. Chap- man writes (77 @/¢t.): The question as to whether Dafhnis belongs to the Lumorphina- or the Philampelina-branch of the Eumorphids (anted, p. 140) 1S apparently rather one of words and sentiments (the personal equation) than of facts. The larva is characterised DAPHNIS NERII. 249 by having the subdorsal line well developed, without trace of ever having been interfered with by modification into eye-spots, but eye- spots are well-developed on the metathoracic segment. This then would be a Philampelid larva with these eye-spots added. Since there is the tendency to break up the subdorsal line into eye-spots in all Sphingids we probably have one result of the tendency here, probably acting also in association with the origin of the Eumorphids. Daphnis would, in fact, seem to be a branch from the Eumorphid stem almost before it was definitely separated from the Philampelid, and whilst it was still possible to retain the greater part of the subdorsal line unchanged. This does not seem to have been possible in any Eumorphid in any stage in which the eye-spots were fully developed, whether on all or only on two segments, at any rate not in-any whole group, though one or two species have a somewhat contrary aspect. Imaginally, Daphnzs is of a totally different wing- pattern from any Eumorphid, but the pupa has a very great resemblance to that of //7ppotion celerio. At first glance they are almost identical, and they resemble one another in a good many points of detail. They do, however, differ in several items, so that it is necessary to conclude that the resemblances are due to convergence. Daphnis pupa, however, with its light colour and weak texture resem- bles those of Eumorphids in being obviously adapted to surface pupa- tion, whilst the pupa of the true Philampelid has a dark colour, and solid texture for subterranean pupation.

Roes., ieee po tt, to, Erisch, /7s5., 7.¢. 3. klabitat im Nero (inne; ys. lVar., xth.ed., p. 490). IMaGo.—gomm.—1iomm. Head and thorax deep olive-green, marked with pinkish-grey (or dull yellow tinged with pink); the abdomen green, marked with faint pinkish-grey oblique lines on either side of each segment dorso-laterally, segmental incisions in ~ upper part of abdomen whitish, a dark patch on either side of anus. Anterior wings dark green, marked with white (or yellowish), suffused with pink; the pale areas consist of a basal circle, treble oblique or angulated line towards base, an oblique median line curving at costa and continued towards anal angle, but stopping short about half-way across wing, a curved line parallel to last almost enclosing apical area and an oblique apical streak; the anal area fawn-grey, edged with pinkish-white, nervures whitish on outer half; fringes green. Posterior wings fawn-colour (or pinkish-grey) at base, a white waved line just outside middle, edged with darker, outer area dark green, anal area whitish; fringes white. - SEXUAL DIMORPHISM.—The @ is larger than the g, though the variations in size are so great as in many cases to mask this. The g has a more conical tapering abdomen, though in cabinet specimens the 2, when devoid of eggs, presents a very similar outline. There 250 BRITISH LEPIDOPTERA. seems to be no difference in colour, marking, or form of wing. The g antenna is the longer, as about 17mm. to 14mm., and is also thicker, as o°8mm to o'5mm. ‘The joints are about equal in number (76), and the scaling is similar to that of other Eumorphids, 77z., one row of very short and two of longer (one a little longer than the other) scales to each segment. The first tibia is longer in the 3S, as 6':omm to about 5‘5mm. ; the ¢ spur is about 3mm. in length, with the comb extending for about two-thirds of this lengtn, the spur is proportionally very broad (1°3mm.); the spur on the @ first tibia is a little shorter (2°5mm.), and the comb extends along about half its length. ‘The fan which the ¢g carries on the 1st abdominal segment (really the znd) arises just behind the spiracle, about the middle of the margin of the dorsal plate, and there passes to it a narrow process from the anterior margin of the ventral plate; this has, no doubt, something to do with the process of erecting and expanding it. It is really a small (for the size of the moth) wisp of hairs about 3°5mm. long. ‘The following spiracles are not in the dorsal plate, but really in the lateral membrane. The marginal batons are obviously modified scales, being distinctly striated, though having the fusiform pointed form they have in other species (Chapman). GYNANDROMORPHISM.—The following are the only gynandro- morphs that we have been able to trace :— a. Imperfect gynandromorph. Wings on both sides equally long; the forewings 47mm. long, left 26mm., right 25mm. broad; a decided difference in the hindwings. Markings and coloration of the wings somewhat different. Left g antenna not quite fully formed, right ¢ normal. Left frenulum perfectly @, the right one, half g¢ and half ¢ ; the little hook on the forewing for fastening the bristle is wanting. Abdomen less pointed than in normal specimens ; segmentation $, being 7-ringed, the last two segments divided by a complete incision, and coloured and marked as in the g¢. On the left side a developed ¢ anal clasp is present, but moved so out of place that it lies obliquely over on the right; the corresponding clasp on the right side is rudimentary (cf Speyer, Stet, ent. Zig., 1868, p. 238). B. Left é, right ¢. As regards sex a perfectly halved hermaphrodite. Right forewing 483mm. long, at the hind margin 263mm. broad, left 46mm. and 24mm. respectively. Coloration of the ¢ wings somewhat deeper. Right antenna ¢?, left g; frenulum and form of the segments likewise. Of the outer sexual organs only the large, somewhat projecting, left anal clasp is distinct ; on the ¢ side the clasp is wanting. Bred by Grentzenberg of Dantzig (cf. Speyer, Stett. ent. Zig., 1869, p. 237). Vesey) nandromorphous ee in Dr. Staudinger’s collection [Staudinger, in. litt. (Schultz, Lil. Woch. f. Ent., ii., p. 393). VARIA TION.— The species ani a certain amount of size variation [British examples are often of good size, ¢e.g., 4ins. 4lin. at eae (Kent), 49ins. at Chickerell (Richardson) |, and sometimes marked colour aberrations occur. Bartel notes (Pal. Gross-Schmett., ll., p. 135) that examples from the neighbourhood of Constantinople are distinguished by their large size and fineness, as also are suchas have fed chiefly on flowers of oleander ; he says that Mitzell, of Berlin, bred really wonderfully magnificent specimens by supplying the larvee with this kind of food and raising the temperature as much as possible. In rare aberrations the green ‘of the upperside becomes yellowish-brown. Unterberger, of Konigsberg, records (///. Zeits. fiir Ent, iil., p. 232) a colour aberration of a g which had the beautiful olive-green of normal examples replaced by olive-brown, becoming ochre-yellow on the underside of the hindwings. The specimens from the Hawaiian Islands are stated by Butler (Z.AZ,1Z, xiv., p. 47) to differ in no DAPHNIS NERII. 251 respect from the typical form. Lederer, however, notes that the Beyrout examples are smaller and duller coloured than those from Dalmatia; Oberthur observes that the Madagascar examples some- times vary in colour, the ground-colour of the wings becoming olive- brown instead of green. Kirby observes (Handbook, &c., iv., p. 40) that “the insect varies chiefly in the lighter or darker shade of the ground colour, and in the amount of reddish or yellowish colour in the band on the forewings.” The only described race appears to be the following : a. vat. ifernelutea,. Saalm., ‘“‘Lep. Madag.,” i., p. 123 (1884); Kirby, “«Cat.,”’ p. 672 (1892).—The specimens of var. imfernelutea, m., before me, from Nossi-Be’, are smaller than European specimens bred from __larve. Mabille also notes the difference- in size as a characteristic of Madagascar specimens ; but no author has recorded any other difference. The coloration of the upperside is paler (blasser), the green tends more towards grass- green, and the paler hindwings have a dingy, ochre-yellow colour above the anal angle before the border, where the green tint is brightest in European specimens, and this colour extends suffusedly towards the apex of the wing. On the underside, the form and position of the markings differ little from those of the upperside, but they exhibit considerable difference in colour, as there is not a trace of green. All the shades which this hue forms in European specimens are here graded from golden orange-yellow to grey-brown. The former colour is brightest before the apex and hinder angle and between nervures 5 and 7, before the marginal area, on the forewings, and on the hindwings in the discoidal cell and before the anal angle; the white in the markings is slightly varied with rosy. The palpi and abdomen are grey-yellow, and the thorax and antennze grey-brown. Among the very large number of European specimens which have been compared there was not one which showed even a trace of any tendency to pass into the orange-yellow of the undersurface. Ovum.—Light green, small (compared with the size of the imago), and agrees somewhat in size, form, and colour with the egg of Sphinx ligustri (Bartel). Ecc.Lavinc.—The egg is attached to a leaf of /Verium, on the underside, adhering to the midrib (Milliere). In central and northern Europe the immigrant females deposit their eggs on the leaves of the oleander-bushes grown in tubs, &c., usually several eggs are laid on one plant (Bartel). Winter notes a 2 captured at Aldeby, Beccles, October 26th, 1857, which laid a number of eggs (Lut. Wk. Wits 1O57, p- 42). Hapits OF LARVA.—In the Riviera the larve of the first brood of imagines (immigrants) live throughout July, and are fullfed from July 15th-30th, whilst the pupal stage lasts only some 16-18 days. The larve of the second brood are fullfed about the end of September, and the imagines emerge some three weeks later (Milliere). In more northern countries both broods are usually somewhat later, dependent on the season. Godart notes, in 1822, that the insect occurs occasionally in Paris, but is common at Genoa, Turin and Nice, whilst, in 1819, the larve were abundant in the dept. Marne- et-Loire. Dormoy writes (Ann. Soc. Ent. France, 1836, pp. 363 et seg.) that, in 1835, the larve occurred in abundance in parts of France where they had never been noticed before, that M. Blanc reported taking 6 larve at Pont St. Esprit in June, 1835, on common oleander, that M. Paris took some 60 larve in August, 1835, at Epernay, on cultivated double oleander, the larve of various sizes, but that all, except a dozen, became feeble and died just before pupation, no doubt owing to a spell of dull wet weather, that M. Paris further reported finding, in ? 1833, the eggs of D. mera on a Das BRITISH LEPIDOPTERA. branch of oleander, and some 52 larve at Montpellier, in 1835, where he had also taken 5 or 6 larve in August, 1834, which produced ima- gines at the end of September. Dormoy expresses the opinion that the 1835 larve resulted from immigrants of 1834, a very improbable suggestion. Nowicki, of Thorn, in West Prussia, records (Preuss. Pro- ving.-Blatt., XiV., pp. 309-311 ; XV., pp. 511-514) the capture of a larva, already past its 4th moult, on August 7th, 1835, as well as two smaller ones, several others having been killed, as well as moths, rather earlier in the year. He observes that the larve only: liked the younger oleander leaves, but took readily to Vinca minor. Siebold (loc. cit., XV.. pp. 103-105) also records larve and the successful breeding of imagines therefrom at Dantzig, and adds that, in 1828, he bred it at Berlin, that, in 1837, they were reported at Chartres (Lesage), and yet appeared to be absent in the south of France. In 1839, Decellier records (Lull. Soc. Ent. Fr., 1839, p. 1x) 17 larve taken at Paris, in mid-September, 1887, in the Faubourg St. Antoine, on cultivated oleanders, all had pupated by October 1st, except one which died. The green colour of the larve disappeared by degrees some days before the change to pupe and the larve became of a very deep brown tint. The larvae and pupe were kept in the shade under a melon-frame, and the 16 imagines appeared between October 7th and 2zoth. Lamek reports (Zool., p. 1514) the capture of twenty larve at the end of August, 1846, at Flottbeck, near Hamburg.- Moeschler notes that, in 1846, larve.were found in numbers on the oleanders in the “ Russian gardens ” at Jankendorf, near Niesky ; Kranz observes that, at Munich, the larve pupate about the middle of August, whilst, in other districts, the larve are still to be found in September. Stein notes (Iris, 1837, p. 104) the larve as being bred commonly every year from the oleanders in the gardens of Berlin, a statement that must be received with great caution. Chaumette records (Zool., 1x., p. 3159) a larva taken on October 27th, 1844, from the Campagne Villamont at Lausanne. In 1849, the larvee were again reported (Lull. Soc. Ent. Fr. 1849, p. lxxv) as being very abundant in the gardens of the Luxembourg (Pierret), and considerable numbers were also found at Abbeville (Fairmaire). In 1852, Paris again notes (/oc. cit., 1852, p. li) that the larve were in. great numbers and the oleanders much injured in the neighbourhood of Fourquex, whilst the same year (loc. cit., p. Ixxi) the larve reappeared at Epernay and -pupated successfully. . Im 1858 (/oc. ci, 1858) spe ccvies number of larve were found at Besancon from which a dozen pupe were obtained (Bruand). Kiunckel reported (loc. cit., 1867, p. 1x11) finding a larva at the end of August in the dept. of Aisne. In 1585, several were found in various parts of France, and, in 1886 (doc. cit., p. lv), several larvae were found at Amiens in September. Bartel notes (Pal. Gross-Schmett., ii, pp. 133-134): ‘‘ The larve attain fullgrowth in from 3-4 weeks, and soon betray their presence on the plants by the quantity they have eaten. .*. . 4) | Uiey are to be found from April to June, and again from August to October, mostly on Verium oleander, preferring the flowers; they grow with extraordinary rapidity, and are usually to be found in some numbers on any plant on which eggs have been laid. Shortly before pupating the larva runs about restlessly, and changes con- siderably in colour. In central Europe the larve frequently perish DAPHNIS NERII. 253 of a sickness the origin of which is probably due to the damp cold weather of the summer and autumn nights. The larve were taken in some numbers by Standfuss, at Breslau, in August, 1893, on Vinca major and V. minor, by Borcherding at Bremen, and by Romanoff in Transcaucasia.” Hering states that in hot summers the larve have been abundant enough in Stettm to do damage to the oleanders in gardens. Caradja notes that his gardener found Jarve in numbers on JVerium oleander at Rome, and he surmises that, as the larva will eat Vinca major and V. minor, the species may become common in central (and perhaps northern) Europe, even to the extent of occurring annually, as does Manduca atropos at the present time. Klooss gives (li. Woch. fiir Eut., 1., p. 483) the following interesting details of the larval habits: Four eggs and eight larve (hatched during the journey) from Malfi (Dal- matia), received July 27th, another egg hatched on the 28th, the other three eggs died. The larve were reared the first 10 days ina glass with a double covering of muslin kept constantly somewhat damp. ‘The food at first consisted of the tender terminal shoots of oleander and leaves of Vinca minor, carefully cleaned from dust; both plants being greedily eaten, the larva growing with extraordinary rapidity. From the roth day onwards they were placed under a wire-gauze covering at an average temperature of 22° C. and in moist air. Freshly-cut succulent food was given twice a day. They developed a tremendous appetite and fed up rapidly. On August 11th, one larva went under the moss, lying on a layer of sand for pupation, and, on the 16th, the last larva similarly disappeared ; the larve pupated in from 3-4 days. Swinton notes that the larve taken at Jerusalem—both green and brown forms—concealed themselves beneath the leaves of the double garden oleanders in a marvellous way, and so that they could only be discovered by their droppings. Those kept in confinement pupated at the commencement of July and the imagines emerged at the close of the day, between July 21st and 26th. Chaumette records the larve as very common at Saugor, in India, on March 3rd, 1865, on (Verium oleander and Tabernaemontana coronaria. Constant says that the larve are some- times common, and at other times apparently absent, in the Riviera, that, in 1900, they were fairly common from August to December, and that from the pup of these some imagines emerged in autumn, whilst others attempted to pass the winter and perished. He says that the larva is easily seen on (Verium oleander, that it sits right up on the branches, and, ‘eating Jike a rabbit,” denudes them conspicu- ously (2 lztt.), a remarkable observation apparently directly opposed to that of Swinton (supra). Costick records (Ent. Wk. Int, vii., p. 140) the capture of two larve of D. neriz near Eastbourne, one on October ooeaerouner on October moth, 1859. ° He states that they fed very well until November, when they became sluggish and ultimately died. He writes: ‘“‘ At first I was inclined to think the larve were those of 4. atropos, the larva of which is sometimes, though rarely, found of a brownish-olive, but, on closer inspection, I observed a difference in the anal horn, that the larve were of a lighter green, and that each had two large ocellated spots. They were found in a field of potatoes in which periwinkle grows, and upon which they fed very eagerly just before they died, and also upon the oleander 254 BRITISH LEPIDOPTERA. at times, but when found they were feeding upon potato.” The larva figured by Curtis (Ariz, Ent., fo. 626) was taken in 1832 at Teignmouth (Zn. Mag., i., p. 116). Larva.—The young larva is yellow with a very long black caudal horn (Boisduval). At the time of its frst moult, the larva is bluish- green, agreeing exactly with the tint of the leaves of the Werzum, on which it rests motionless during the day, and is thus difficult to detect. The subdorsal line is broad and yellowish, and extends from the 4th to the r2th segment inclusive. The head is small, concolorous, with three ocellated spots on either side. The legs are washed with carmine at their extremity. The caudal horn is haired through- out its length, and presents three colours—yellowish laterally, black above, with the extremity of the point of a clear white. The stigmata, which are whitish-yellow, are invisible to the naked eye. Below the subdorsal line, from segments 4 to 9, there is a series of whitish dots encircled by azure-blue. The two ocellated spots of the 4th segment, of a bright azure-blue, are already very conspicuous, and, when the larva is disturbed, they increase in brightness, and then acquire a sort of ‘‘fulguration” that disappears with the danger. [This peculiarity has not been observed in the adult larva.] The most striking feature of the young larva is the enormous development of the caudal horn on the rith segment; one might say that this is, in its length, in direct opposition to its smallness in the later larval stadia (Millitre). The larva in its early stages is yellowish with a strikingly long, finely, but roughly, granulated, black horn. On the sides are ocellated spots which it retains until pupation. Later, the larva becomes green or light rose-red, with a slight bluish tinge dorsally. The thoracic segments, the last, and sometimes also the 4th, are either yellowish, citron-yellow, or lght green. More rarely the whole body is, according to the age of the larva, orange, ochre-yellow, brown-yellow or bronzy-green. When /fudlgrown the larva measures from rz0omm. to 150mm. in length; a large, reniform, blue, ocellated spot with a blue-black margin is situated on the upper part of either side of the 3rd segment; it has a double white pupil, sometimes faintly surrounded by yellow, and occasionally has, instead of the double white pupil, only a bluish-white shade medially. From segments 4 to 11 is a white, light yellow, or full yellow, stripe, running along the sides of the dorsum, and in which appear white dots, surrounded with bluish, whilst above and below this stripe similar dots are scattered over the ground-colour. This stripe is bluish-margined beneath, and, in it, stand the black, yellow- margined spiracles. The true legs are brown-red, in the nearly full- grown larva bluish. Head of the ground-colour. The short and ill- developed caudal horn is thicker below, chiefly citron- or wax-yellow, exteriorly white, and black at the tip, at its base aculeate (Bartel). Elongated and attenuated anteriorly ; the three anterior segments retrac- tile (as in larvee of Eumorpha elpenor and Lippotion celerio). Head small and globular; caudal horn small, short and thick, and bent back- wards, of a pale carrot colour; two large round ocellated spots, . bright blue in tint, paler towards the centre, bordered by black, and then surrounded by green on the 3rd segment; the ground- colour is of a pale glaucous-green, inclining to dull yellow on the anterior and posterior segments ; a broad lateral white line, DAPHNIS NERII, a0 rather ill-defined and marked with round white spots, bordered by dull green, extends on either side from the 5th segment to the caudal horn; the anterior edge of these segments is also marked with several similar spots; the head and the thoracic legs pale green ; the membranous prolegs pale greyish-green tipped with brown ; stigmata narrow, black, bordered by white; abdomen dull greenish-yellow or greyish-green (Chaumette, Zoo/., ix., p. 3158). Green, with a prominent, whitish, bluish-bordered, longitudinal lateral band from the sixth segment to base of horn; the band traversed by white oval spots ;. above and below is a clustered series of white spots, and others bordering the segments over the back; a large purple-centred black-ringed blind ocellus on side of 4th seg- ment; spiracles small, black; horn yellow. Before changing, the larvee become pale brownish-red, with the black, lateral ocellus, a spot on second segment, and the head dull black, the white lateral clustered spots showing out prominently (Moore). A larva fast gth moult, was about 4ins. long, light green in colour (almost sea-green) dorsally, darker laterally, with a white lateral line beginning on the 5th segment, and terminating at the yellow horn. The small, somewhat cleft head, green; on each segment white spots above the white line; the thoracic segments yellowish-green, with a round spot, light blue centrally, darker blue at its margin. ‘The spiracles black, surrounded with a white ring (Nowicki). FIGURES OF LARVA OF DAPHNISNERII.—I. Roesel gives (/nsecten- Belustigung, vol. ii1., tab. xv) three figures of the larva: (1) The first (green) form is green in colour, shading on the rst abdominal segment into yellow, yellow predominating on the thoracic segments and on the 9th abdominal and horn; the head green. The yellowish-white subdorsal line starts [as all subdorsai (of Weismann) lines of Eumorphids do] from horn and passes forwards, broad and strongly marked to middle of 1st abdominal, 7., to end of green colouring, being slightly narrower on this segment. The abdominal segments show g or 10 subsegments, although fewer are indicated [8 or 9] on figures 2 and 3, but the figures are from different angles, and the subsegmenta- tion of larve varies at different parts of segment, and the subsegments seen vary according to how many are obscured at incisions, by attitude of larva. On metathorax are five subsegments and on the first two of these, in line with the subdorsal line, is a large blue eye-spot, partially divided, as if each subsegment had a separate one and these had begun to coalesce. (2) The second figure is of an orange- or brownish-yellow. The subdorsal line white, except that it is yellowish on part of the 7th and 8th abdominals, it proceeds forwards, nearly of the ground-colour from middle of 1st abdominal (yellowish not white), right to the head; head yellow. On the abdominal segments the dorsum is shaded with paler, a darker shade crosses the dorsum of first subsegment, and, from the margin of the light dorsal shade, occupies the next subsegment down to the subdorsal line—of each following subsegment it occupies less, till, on the last (or last but one also), it is absent. Its upper border thus forms an oblique line in reverse direction to that of Séhznx, but agreeing with that usual in Nephelids (and some Eumorphids), a similar dark shade occurs below the sub- dorsal line, extending to below the spiracular level, but interrupted by a yellow area round the spiracle (which is a dark spot). The 256 BRITISH LEPIDOPTERA. eye-spot as in larva 1, except that the rst member ot the eye- spot is the larger, in 1 it is, if anything, rather smaller, the subdorsal line is interrupted by it, the upper margin being about the middle of the spot. The line does not widen or alter, but looks as if it might go straight through unaffected, and had the spot superposed, hiding a portion of it. (3) The third figure is also brown or orange-yellow, but the dark shade of fig. 2 is here very much darker, nearly black, and occupies the whole area dorsal to the subdorsal line (and a little below it as in 2), it also somewhat invades the subdorsal line on the 8th abdominal. Eye-spots the same, two portions equal. The subdorsal line stops at the front of the 1st abdominal. There is a black dorsal plate on the rst thoracic segment. On all three larve are white (shagreen ?) dots along the subsegments, confined to the area that is dark in fig. 2, and invading the subdorsal line on abdominal segments 1, 2 and 3. In fig. 2, the dark shade with dots is shown as breaking through the subdorsal line in the middle of the 3rd abdominal. The eye-spots are blue with black border and central white pupil. II. Sepp gives (Wed. Jnsecten, vol. vi., pl. xxi) two figures (of the same larva?): (4—5) The first is a lateral, the other a more dorsal view, both are green, with a yellowish shade on the thorax, the 1st and 8th to roth abdominal segments distinctly darker green, just above the subdorsal line. The white dots are fewer than in Roesel’s figures; the eye-spots are round, divided by a central subsegmental line; they consist of a black circle, shading through blue into central white, with a yellow line outside. There are 7 subsegments shown in abdominal segments. The subdorsal line stops at anterior margin of the 2nd abdominal. A good deal of the drawing has been done by the colorist (of the hand-coloured plate) and one does not trust it all too much. (6) Sepp figures another (doc. ciz., pl. xxu*):; Abdominal segsments 2) sees emaems and 8, above the subdorsal line, blackish-green, thorax and _ tst abdominal greenish-yellow, 8 (below line) 9 and to yellow. A few shagreen-dots shown, and the subdorsal line, (not on 1 but) on the 2nd, 3rd, 4th, 5th, 6th, 7th abdominal segments, shows as consist- ing of shagreen-dots, closely placed on the subsegmental lines, on 8 it is a white stripe. Eye-spot with yellow outer line and central division, outer margin undivided. III. Dubois figures (Zép. Belg., 1., fig. 103?) the only larva he ever took. (7) This is green, with darker shading dorsally, widening to posterior border of segments. The subdorsal line extends to the front margin of 1st abdominal, which is coloured as the other abdominal segments, and shows an abrupt transition to the yellow thoracic segments, a bluish shading below line with a little yellow round spiracles; head green; horn yellow; yellow line on anal plate and 8th, gth and roth abdominal; segment otherwise green ; 9-10 subsegments; 3rd thoracic shown with 9 subseg- ments and eye-spot occupies 6 of these (2-7), it is figured as by Roesel but even more double; no white dots are represented ; head green. This strikes one as a very honest good figure, if not of good * Hoffmann (Rawpen Gross-Schmett., pl. viii., fig. 3a), seems to be obviously a copy (not bad) of Sepp’s pl. xxii. Barrett’s (Zep. Grit., i, pl. 53, fig. 1) is a copy of this copy. DAPHNIS NERII, DAS artistic finish. IV. Boisduval (Lc. Chenzlles, pl. iii., fig. 1): (8) A very diagrammatic figure, tolerably uniform smooth green, spiracles with a yellow line round each. Eye-spots very large, single; shagreen- spots shown; subdorsal line white, shown as seven oval (subseg- mental) marks on each segment. V. Horsfield and Moore (Ca¢. eis. cpl. x. ie. 3).- (9) Rather diagrammatic, head and prothorax green, meso- and metathorax yellow, venter and hinder part of body yellow, rest blue!!, with white subdorsal line bordered with yellow above, shagreen-dots diagrammatically indicated, eye-spot in line of subdorsal line. This division of the 1st thoracic into two is shown in several figures, no other shows so great a division of the 3rd into two portions as this. VI. Hubner (Zavrv. ep e Spiiiezes, ~\. Wi.,-fig., 1): (10) Head preen, thorax and ist abdominal yellow; body green, 8 subsegments shown, horn yellow ; white subdorsal line, uniform width, but with incisions of subsegmentation lined through it from horn to anterior border of znd abdominal when it stops abruptly; some lilac tinting on green ground-colour below the line; some yellow on prolegs and round spiracles, which are black; shagreen-dots shown, some also, in the line of the subdorsal line, on the rst abdominal. Eye-spots very dorsal, lower margin level with the lower margin of the subdorsal line ; also very double, each portion of about equal size. VARIATION OF LARVA.—We have already given notes (szpra) of the various forms of the larve figured. Swinton records that, at Jerusalem, two forms of the larva were to be obtained—green and brown ; Jones also obtained a larva of the brown form at Riva on July Bieenoce. | lreitschke and- Kollar note (Dze Schmetz., x., p. 123) that each of them had had a larva that was of a bronze colour, the front segments rose-red, a dark longitudinal stripe running to the anus; the anus and legs dull rose-colour. Cocoon.—The larva forms a long silken covering on the ground in which to pupate (Moore). Similarly to most of the larve of this group, this species does not enter the ground to pupate, but makes a sort of cocoon with the débris of leaves, which it unites with some strands of silk (Boisduval). The. larva pupates on the earth in a loose cocoon, mingled with particles of earth and dry leaves (Bartel). Larvee spun loose” cocoons under moss lying on a layer of sand in their breeding-cage (Klooss). Pupa.— A ‘large pupa, fully Jonger fra Manduca atropos but NOt quite so stout, 2:5 inches to 3 inches im length, this latter measurement would represent a large specimen moderately extended, °6251n. broad. Form much that of a Phryxid or Eumorphid pupa, the 5th, 6th, and 7th abdominal segments narrowing gradually, the 8th, 9th and roth rather abruptly. The colour is a very pale brown (khaki, terra-cotta or nankeen) with some black markings and a sprinkling of fine black dots. The most conspicuous black marks are round the spiracles (thoracic and on the 2nd, 3rd, 4th, 5th, 6th, 7th and 8th abdominal), forming a row of conspicuous black marks, fairly constant in size, the largest, on the 4th abdominal, being about 25mm. in diameter. The colour and markings aiewaveby similar to those of the pupa ot Azppotion celerw. A fine black line runs narrowly down the maxilla, affecting in front little more’ than the median suture, posteriorly the whole width of R 258 BRITISH LEPIDOPTERA, the maxillze where they are narrower. There is also a black dorsal line running down the thorax, and, in some specimens, existing more or less on the abdominal segments. The only other black marks that do not appear to belong to the scattered black points are a series of spots, placed subdorsally on the anterior margins of the 3rd thoracic and abdominal segments, varying in intensity in different specimens. The 8th abdominal spiracle is closed, but, otherwise, is as well marked, as to size, structure, and black marking, as the others. The general surface is finely pitted and the pits connected .by fine. depressed lines, the thorax is smoother and the appendage-cases fairly smooth, the wing-cases well marked by neuration and Poulton’s line. Laterally, abdominal segments 5, 6 and 7, where covered and exposed in pupal movements, present areas of a different structure, extending backwards to the spiracles, but narrowing to nothing anteriorly and posteriorly ; these surfaces are covered with short transverse ridges, with sharp edges and dark margins, and, where they fade into the general surface, they show by transition that these ridges are special developments of the pupal surfaces between the depressed lines connecting the pits, which arrange themselves transversely as they approach this special area. The anal armature is a short black conical point, 1°5mm. long, ending in a minute double spine. The anal depression is well-marked, the sexual lines less so, but quite distinct. Four pupz in the possession of M. Constant, one of which was alive (March, 1901) were all affected by two curious defects or malformations. One of these was that the proboscis did not reach the end of the wings: by -z51ni)) eave mea unoccupied gap; the other was that the anterior apex of the 2nd tibia, where it meets the rst tibia and the antenna, had its point similarly absent, leaving a bare gap or depression (Chapman). The pupa is 58mm. in length, its greatest girth, near the extremity of the wing-cases, being 44mm. It tapers towards both extremities, the head being rather small, but not possessing, as in the case of Theretra porcellus and Eumorpha elpenor, so pronounced a keel containing the maxilla. The anal spike is short, and not curved under towards the ventral surface; moreover, the ring of sharp points, found on three of the abdominal segments of the pupe ot the two moths just named, is absent from that of D. mera. The colour is a rich pale sienna-brown, lighter inside the junctions of the segments, slightly darker on the back. The segments have a few scattered small black spots on the back, and on the under- surface also. There is a black streak, in some places quite 1mm. wide, on the thorax along the middle line, but disconnected on the head, and a black spot appears on each side of the head. On the undersurface a black line, ‘5mm. wide, extends along the centre, from the base of the wing-cases to the anterior extremity. The antenne and leg-cases are olive-brown. The spiracles are set ina black spot (Lucas). The slender pupa is brownish-yellow dorsally, with the exception of the wing-cases, and finely dotted with black at the segmental incisions ; the spiracles stand in large black spots ; the cremaster is short with two fine terminal points slightly curved outwards (Bartel). The pupz are light brown at first but at the end of 5 or 6 days have become wholly black (Decellier). ForcinG pup&.—Klooss, who reared this species successfully, DAPHNIS NERII. 259 states (ll. Woch. fiir Ent., i., p. 483) that the cocoons were spun among moss lying on a layer ot sand, that the moss was damped moderately every three days, and that the eight pupe, which had accomplished their change between August r11th-16th, gave up their imagines on September 14th and the eight following days. Five Qs and 3 gs emerged, all well-developed, the wing expanse vary- ing between 1ocm. and t1o'7cm., although one specimen measures only gcm. FooppLants. — Lerium (Linné), Nertum odoratum, Cinchona (Moore), Vinca major, V. minor (Standfuss), [Rumex (Staudinger) is stated to be an error by Bartel], Verium oleander, preferring the flowers (Bartel), potato (Costick), Zabernaemontana coronaria (Chau- mette). In Paris almost always on the double-flowered (Veriwm odoratum (Boisduval), Apocynum venetum, Asclepias syriaca (Bouché). Hasits.—Very rarely obtained in Britain, and, even in the south of Europe, only occurs as an irregular immigrant in June-July in occasional seasons, the immigrants laying eggs in suitable places and producing a second brood in late September and October, the examples of which, in their turn, also appear to move considerable distances, and to supply us with most of our occasional British captures. Treitschke notes (ze Schmett., x., p. 128) that this migrant was entirely absent from Vienna for several years in succes- sion, but that, from 18209, it occurred every year, and, in the cold and rainy summer of 1833, the larvae were met with fairly frequently, but not till the end of September and on to the middle of October. Most of these resulted in failure, but Treitschke was pretty fortunate, rearing 11 moths from 15 larve, some of which were found when quite small. In favourable years he states that he succeeded in rearing nearly all. The years 1834-5, 1846 and 1885 were exceptionally favourable for the species along the Mediterranean littoral, and, during these periods, the insect was exceptionally abundant at Montpellier, Palermo, Cannes, Nice, Monte Carlo, &c., but it also spread much further north, being found in some numbers at Paris, and in Germany, in Upper Lusatia, the Rhine provinces, &c.* Dormoy, on the authority of Daube, whose observations were made at Mont- pellier, considers (Ann. Soc. Ent. Fr., 1836, p. 363) that the abundance of D. nerii in France, in 1835, was due to the continuance of strong winds from the south in 1834, that he saw imagines some 20 times come to the shore and alight on the first flowers that they encountered, in the latter year, but only when the south wind was driving them, and he suggests that the migrants came from Africa. In the other years, the August imagines were followed by larve in September, and such imagines as emerged from the pup obtained were produced in Novem- ber and December of the same year. In 1900 and 1902, again, the species was common on the Mediterranean littoral, but few of the many larve obtained produced imagines. Its natural habit, according to Bartel, is to fly to flowers, petunias being noted as the favourite. It is recorded by Winter as hovering over passion-flowers at Brighton (Zool., p. 3624), flying round honeysuckle at Stoke Flem- ing, just after dusk (Owen), but otherwise the examples in Britain * Hering and Cornelius give (Stett. Evt. Zeit., vili., pp. 131-140) some detailed notes on its occurrence in Germany (especially about Elberteld) in 1846. 260 | BRITISH LEPIDOPTERA. have been more frequently taken at light or at rest. Thus we have it recorded as: Flying into an open window to light at Brighton (Thorncroft and Tidy), also into a room at Glasgow (Wilson), a @ flew into a window at about 6.30 p.m. to light at Yalding (Reid), and at one of the electric lights at Eastbourne (Alford) ; also it is re- corded as resting on an oleander plant at St. Leonards (Smith), on a heliotrope plant in a garden at Aldeby (Winter), at rest on a scariet- runner plant at Tottenham (Pool), on the stalk of a lly bud at Brighton (Langley), in a garden at St. Leonards (Wood), also at Lewes (Hillman), in a garden at Hemel Hempstead (Piffard), in a garden near Birmingham (Enock), on a sheaf of corn at Barrhead (Grant), on the gatepost of a timber-yard at Hartlepool (Gardner), resting on a pine trunk at Niesky (Moeschler). TIME OF APPEARANCE.—Imagines are usually taken in temperate Europe (southern and central) in Jul y and September-October, the latter brood being the progeny of the former. In its permanent subtropical habitats in Africa and Asia the species appears to be continuously- brooded, and it is undoubtedly only an immigrant therefrom in the temperate zones of the Old World. The imagines of January- February produce fullfed larve in early March (March ard, 1305, at Saugor) in India, and these yield imagines again in April. These give another brood of imagines in June-July (July 2rst-26th at Jerusalem) which probably represents the earlier immigrants that reach Europe in June and July, earlier on later according to ‘the district whence they have come. Imagines were reared at the end of September, 1834, from larve found in mid-August in Montpellier (Paris), also 16 imagines emerged between October 7th and 2eth, £839, from September larvee, all of whiehpiad puUpatede betore, October iste at wimanise( Decelirer): In wes. Nowicki bred imagines in November from August larve at Thorn in West Prussia, and Siebold, bred one on November 6th from a September larva, taken at Dantzig the same year. In 1885, larvee were already ful lIfed in the Riviera from July r5th-3oth, from which imagines appeared in August (Milhere); in 1893, the larve were not fullfed at Breslau until early August (Standfuss), whilst in 1896, eggs, from Malfi in Dalmatia, were already hatching on July 27th-28th, and the imagines emerged from September 14th- 22nd. ‘These July imagines, then, give another brood of imagines in September, which, in due course, give the October and November larve and the January-February specimens, a brood that never reaches maturity in Europe unless forced *, and then generally emerges somewhat earlier, e¢.g., December znd, 1846, at Paris (Pierret) ; January 7th, 1887, at Cannes (Warburg), &c. According to Marchal, the larve in Mauritius are fullfed in February, April, June, September: and December, the imagines appearing in each case about 20 days later (Boisduval). Lederer says that the species always occurs in two generations: at Beyrout, the larvae * There is considerable evidence that late larve rarely reach the pupal stage in Europe, and that when they do they usually die unless forced, e.g¢., Morres found a fair number of larvae and pupz on the Riviera, the pupz were dug up in February and were dead, Constant obtained four late pupe (from a considerable number of larvae, which were common) in 1900, three were already dead in March. In 1902, Powell :eared many imagines in September and October at Hyéres, a few pupz went on into the winter but all had died by March, 1903. DAPHNIS NERII. 961 in spring and autumn somewhat commonly.

It was seven or eight feet from the ground on the north side of the tree.’ We cannot altogether understand Leech’s remarks above.» At the present time Pryer’s and Leech’s examples are all in the British Museum collection. Not only is the ground colour of the eastern (Japanese and Chinese) race characteristically different from all other forms represented, but the coppery tint in the dark ground colour of the wings, the dark, almost unicolorous, thorax and abdomen, the ill-developed markings and smaller size give this race a most marked facies. The palest of Pryer’s ex- amples in no way approaches the European form. We may point out that the ca/zgineus form exhibits, zz¢éer se, much aberrational variation ; thus we have: (1) Unicolorous grey, with two faint coppery-tinged transverse lines. (2) As in 1, but with white median discal spots. (3) Unicolorous grey, with slight coppery tinge, with the three typical lineole.

EccLayinc.—The eggs are laid singly on the needles of the pine in June and July (Roesel), but, although this may be so generally, sometimes little groups of from two to a dozen are laid together, the @ resting for oviposition and not performing the operation on the wing, the eggs being laid almost as soon as copulation is completed (Head, and Werneburg also notes that the eggs are laid irregularly in small groups of from to0-15 on the sides of the pine- needles, mostly at the top of the stems. Hartig records that the egg stage generally lasts from 10-14 days. Head forwarded us some eggs that had been deposited in confinement on July 6th, and these hatched July 18th-19th, tg0o1 ; Oldaker records ova that hatched July 13th, 1o0r, whilst Buckler received some’ from Heyne or Leipzig on July 26th, 1882, that hatched between July 29th and August 2nd. Ovum.—Rather over 2mm. in length and 1°75mm. in width. In outline an almost perfect oval, the micropylar end being slightly broader and rounder than the opposite end. ‘The surface is almost smooth, with a faint reticulation developing into a more marked, but still superficial, irregular polygonal network towards the micropylar end, the cells or areas becoming very distinctly defined the nearer one approaches the micropyle; they are also fairly well- developed at its nadir. On the upper-surface, towards the micropylar end, a sinall somewhat shallow depression of oval or circular outline. Colour bright green, distinctly brown towards the micropylar end (ap- parently the head of developing larva), this brown area being yellowish, HYLOICUS PINASTRI. 981 then buff before becoming brown ; tint yellowish-green towards its nadir. The contents also vive rise to longitudinal yellow bands, again evidently the embryo. The micropylar area itself is slightly de- pressed. There is considerable variation in size, some of the eggs having apparently not more than # the cubical contents of others. The eggs are evidently attached, those described having been separated from the surface on which they were laid (Tutt. Described July roth, rg01, from ova received from Mr. Head, and laid July 6th). The eggs are as large as those of Smerinthus populz, but not so round, the shape being roundish ovate; the surface smooth and glossy, and their colour, when received, of a light greenish- ochreous-yellow, or pale olive-yellow ; some were clouded within with brown, in some instances with quite dark brown at the end; the shell had a pearly lustre. Before hatching, the dark lobes of the-embryonic head were distinctly visible at one end (Buckler). Yellowish, shining, oval, of the size of millet seed (Roesel). The eggs are figured by Ratzeburg (Forst-Jnsecten, i1., pl. 11., fig. 32). HaBiTts OF LARVA.—The newly-hatched larva is quite unlike that of any young Sphingid larva that I have previously seen both in general appearance and behaviour. It is short, stout, active and restless in crawling, curves its body and has a writhing or wriggling manner that is quite foreign to the usual method of crawling adopted by young Sphingid larve; it appears also to be less stiff and more flaccid than other Sphingid larve (Bacot). The young larve, when first hatched, eat along the side of the needle-like leaves of /unus, but, after the second moult, they attack it from the end and bite it quite through, thus continuing to eat as they gradually step backwards and as the needle becomes shortened, until the leaf is consumed close up to the sheath at the twig or stem. Just before entering the earth, the larve cover their skins all over with some fluid discharged from their mouths (Poulton makes a similar ob- servation about the larva of Sesza stellatarum) [Buckler]; Thellusson observes (Zut. Rec., vil., p. 132): The first and last moults appear to be the most dangerous periods for the larve, otherwise they seem to be fairly easy to rear; feeding them on too green and succulent food, also, produces diarrhoea and the larve turn almost to water. - They feed exclusively on the pine, beginning on the top of the firs and eating downwards to the stalk, and, in confinement, they appear to eat by — night and day. The young larve are stated by Ratzeburg to spin silk for a holding surface, and he adds that the habit is continued even after the second moult; he also observes that, when quite young, they merely nibble the needles, but later eat them right off. Nickerl says that, in 1827, the larve appeared at Brandreis, in such numbers that, in certain firwoods, the trees were completely stripped, and that the pupz were so abundant in the autumn that they were used for feeding swine. Alderson notes (zz /#tt.) that the larve imitate excellently the needles and twigs of fir; he observes that, as the larvae commence eating from the top of a needle and continue downwards, the green colour of the young larve matches well the tint of the needles, whilst, as they become larger they match the twig, ze, the -bark whence the needles spring, so that, by the time they clear off the needles from a branch, they are difficult to see because they match the bark so closely. Bartel notes (Pal. Gross-Schmett., li. p. 49) 982 BRITISH LEPIDOPTERA. that the larva lives from June to October on conifers, to which it is often very injurious, it is usually found on the pine ( Pinus sylvestris, the black pine (P. dariczs), P. pinaster, P. strobus, and more rarely on Adzes alba, Picea excelsa and Larix decidua. Larve are sometimes found right on into November, and, at Wiesbaden, have even been found in December ; such late larvee must certainly spring, one suspects, from moths which did not emerge until late in the year, although possibly not belonging to a second generation. Ratzeburg says that, although Bechstein reckons the species among those more than usually injurious to forests, yet no recent observations have confirmed the statement, although it is probable that it sometimes deserves the epithet, for, in some years, and always in common with the larve of Dendrolimus pint, it is very abundant locally, e.g, in the Annaburg preserve in the years 1837 and 1838, when both species were in exceptional numbers. Chaumette says that, in Switzerland, the larva is found in August and September on Adzes excelsa and Pinus sylvestris. Larve are to be found in the Linz district from July to September some were taken at Pfeningberg on September 14th, 1896 (Himsl), chiefly in August and September in the Netherlands (Snellen), captured from August 8th-September i7th, in the Auvergne district (Sand). Larva.—/irst instar: Short, stout and active, body cylindrical with a well-marked lateral flange for so young a larva. Head and thoracic segments large; caudal horn very stout and fleshy- looking, with a very marked fork at the top, this fork is strongly- developed and the prongs much thicker and heavier than in any other Sphingid larva that I have examined; the horn and its bifurcations have a curious worm-like appearance owing to their smooth surface and slight irregularities of thickness and direction ; the surface of the horn shiny, chitinous-looking, somewhat irregularly granulated, but devoid of spicules or hairs except the sete arising from tubercles i at apex of fork. The colour of the body dirty-yellowish ; scutellar plate not very noticeable; true legs black ; prolegs with black chitinous plate on outer sides ; subsegments poorly marked, the abdominal segments subdivided into 8 subsegments; sete fine, but long compared with those of Celerio gall and Theretra porcellus, fairly stiff and tapering to a point, and rising from conical, somewhat inconspicuous chitinous brown tubercular bases; on the abdominal seg- ments, the sete i and ii are arranged trapezoidally, nearly as if at the four corners of a square and apparently with only one subsegment between; on the meso- and metathorax i and ii are on the same subsegment, and the same chitinous plate appears to carry both setz, although their bases are slightly apart, 1 appears to be placed outside, ii just within; 11 is a slightly larger seta, placed vertically above the spiracle; on the meso- and metathorax this is a two-haired tubercle, each seta with its own separate base on a common plate, the sete placed one above the other, and both rather higher than is ili on the abdominal segments; _ iv and v are situated on a lateral flange, iv almost directly beneath the spiracle, and v far forward on the anterior margin of the segment, and almost on a level with the spiracle; on the meso- and metathorax only one seta is present on the lateral flange, this is situated just in front of the centre of the segment and would appear HYLOICUS PINASTRI. 983 from its position to be iv, but, judging by analogy with other species, is probably v; on the prothorax the prespiracular seta (v) appears to be duplicated and both sete are situated on the same chitinous plate; the dorsal tubercles are, as usual, arranged in two transverse rows, one on the anterior, the other on the posterior, margin of the scutellar plate; vi is present beneath the lateral flange. The surface of the head rather granular; the pale areas thereon mottled or tesselated with dark colour [Bacot. July zoth, 1go1]. Before the first moult, the larva is yellowish-brown with a broad brownish dorsal stripe, light-margined on either side, and with a short black horn ; a yellowish stripe runs across the brown legs, whilst, at the sides of the dorsum, is a line of the same colour ; head margined with blackish-brown (Bartel, Pal. Gross-Schmett., 1., p. 48). First instar: The young larva (emerged from egg July 2o9th, 1882) was of a light greenish-ochreous, with the two lobes of the head broadly marked with dull black-brown; the anterior legs were black, the ventral prolegs were barred outside with dark brown just above the feet, the caudal horn, which was a iittle flattened and slightly bifurcate at the tip, was dull brownish-black ; a faint brownish dorsal line was just visible. After feeding for two or three days on Pinus, the body became greener and showed faintly paler green sub- dorsal lines and a faint yellowish spiracular line. On August 5th, some of the larve were laid up to moult, their skins shining green, with the front edge of the second segment pale cream colour, in striking contrast to their copper-coloured heads, marked with blackish on each lobe. Second instar: On August 6th one had accomplished its first moult; its head, which was very similar in shape to that of the larva of a Smerinthid, was now of a pale green, marked with a black streak down each lobe from the apex of the crown, the black streaks shortly afterwards were margined externally with yellow streaks, the upper lip outlined with black and the mouth black; the body was green, the back being of a deeper green than the sides, with subdorsal lines of whitish-green, and with a fine whitish-green lateral line followed by a stripe of the same deep green colour as the back, which blends a little below into a yellowish whitish-green spiracular stripe, that is abruptly contrasted beneath by the deep-green belly ; the black caudal horn on the twelfth segment was of the same shape as before; all the legs | as before. By August goth several of the larve had grown to be 14mm. long. TZhird instar: On August 12th several had moulted the second time; the green colour was full and bright, the pale yellow lines were of about equal stoutness, the spiracular line being just the least degree the stouter, the yellow stripes on each side of the head were bright, edging the black stripes; the caudal horn was reddish-brown and glossy, with the tip black, slightly bifurcate and flattened; the larve at this time no longer ate along the side of a needle-leaf, but attacked it from the end, biting it quite through, and thus continued to munch, gradually stepping backwards as they shortened the needle, till the needle was consumed close up to the sheath at the twig or stem. Fourth instar: Between August 16th and 18th several of the larve had moulted the third time. The spiracular line was now a little interrupted at the end of each segment; the head, the anterior legs and ventral 984 BRITISH LEPIDOPTERA. prolegs were now glossy, smooth and red, and the hinder half of the anal prolegs, anal flap and rough caudal horn were glossy, but with minute black points ; the caudal horn was now curved, and, viewed in profile, tapered to a rather fine point, but, viewed from above, was seen to be slightly forked at the blackish extremity ; the spiracles were red, finely outlined with black. fth instar: Between August 26th-z9th most of the larvze moulted for the fourth time, and, on the Jast day of August and September rst, I figured the most advanced, (pl. xxii, he. 21), which was’ then 21al%5 nessa length, its proportions were slender, the head somewhat bluntly conical, the segmental divisions were rather deep, as were also the subdividing wrinkles, eight in number on each segment beyond the thoracic segments, excepting the 12th, which bore the rough curved caudal horn; these deep wrinkles were blackish-brown and made the segments appear like a series of rings. The colouring and design of the larva were now -very beautiful, the skin soft and smooth, the head, plate of second segment, the anterior legs, ventral prolegs, the hinder parts of the anal prolegs, the anal flap and the caudal horn were all as glossy as if highly varnished, and were sprinkled with raised black dots; the broadish dorsal stripe became gradually thicker towards the middle of each _ seg- ment and then narrowed as gradually towards the end, the white or yellowish stripe by which it was bounded was consequently thicker at the beginning and at the end of each segment than in the middle; this was beautifully relieved by a stripe of the full and bright green ground-colour, followed by another or subdorsal white stripe, which also gradually widened to the middle of each segment, in which was set the orange-red spiracle, edged with black ; close beneath this was the slightly inflated pale yellowish Spiracular stripe, imterrupted at the end of each segmentseithe belly was wholly of the green ground-colour; the head was orange- reddish, more or less tinged with greenish, the deep yellow stripes at the side were bordered in front with rather dark red and behind with deep red, the latter bordering being broader below and shading above gradually into the ochreous-green colour of the back of the head. By September 3rd, this larva had grown to be 3in. alin. when stretched out, and the white stripes were becoming interrupted in the middle ; the front edge of the second segment (next the head) was of a dark-blue green, and a streak of shining reddish-black was situated in front above the base of each of the anterior legs. This larva went down for pupation on September 5th (Buckler), The fullgrown larva is smooth and elongated ;_ the anal horn slightly curved ; the head round; the ground-colour fine sage-green, wrinkled transversely with dark brown; a very broad pinkish-grey dorsal line, somewhat dilated towards the posterior part of each segment, bordered by an interrupted whitish line, on either side of which is another whitish, and rather interrupted, longitudinal line; also an interrupted, pale yellow, lateral line just below the stigmata, between which and the longitudinal whitish line above-mentioned, is another irregular and macular ill-defined line. Abdomen green, wrinkled with black, and a patch of dull pinkish-yellow in the middle of each segment; the stigmata orange-red, bordered by black. Head pale yellowish-brown, with two short and thick black dashes above, HYLOICUS PINASTRI. ; 285 and streaked on the sides with brown, more or less dark ; mandibles shining brown; caudal horn black and slightly granulated. Thoracic legs very pale straw-colour, and slightly tipped with brown. —Prolegs dull pinkish-yellow, with two grey patches on each. Escutcheon dark shining brown, traversed by the fine dorsal and longitudinal lines, which appear of a pale buff colour (Chaumette). Larva levis, glauca, linea laterali flava. Caput luteum.

Vat. xiith ed., pp. 802-803). There is a very detailed description of the larva from hatching to pupation (in 6 * instars) by Hartig in Liebich’s Alle. Forst-und Fag.-Fourn., vi., p. 177; the larva is also mentioned by Ratzeburg, /ors+/nsecten, i1., pp. 74 ef seg. VARIATION OF LARVA.—The adult stage of the larva of JZ. pinastri-is very variable, as shown by the figures in various works. The variations arise on the one hand from the struggle between the green ground-colour and the reddish-brown extending from above, and, on the other hand, from a more or less complete disappearance of the associated longitudinal lines. The latter are sometimes completely retained, this being the casein a caterpillar figured by Hubner (Larvae, Sphinges, i11., Legitimz C, 4), where both the subdor- sal and supraspiracular lines are continuous from segment 11 to seg- ment I, an instance which may, perhaps, be regarded as a reversion to the primary form. It has long been known that, in the larva of this species, the mixture of brown and fir-green, interspersed with conspicuous light yellowish and white spots, causes the adult larva to present a very perfect adaptation to its environment. Roesel says: ‘“ After eating, the larva remains motionless, and is then difficult to see because it is of the same colour as its food, since its brown dorsal line has almost the colour of the pine-twigs, and who is not familiar with the fact that, beneath the green needles, there is also much yellow to be found.” This adaptation to the needles and twigs obviously explains why this larva, in the adult condition, is so far removed from those of Sfhznx, with which the moths are so nearly related (Weismann). Thellusson states that the larve found at Woodbridge were most variable in colour, some bright green, others, in their last two stadia, varying from green to brown, whilst others again were quite purplish in hue. Ratzeburg notes that, before pupation, the larva shrinks much and often changes its colour most strikingly. DEVELOPMENT OF LARVAL MARKINGS.—/?rst mstar: The larve are 6mm. in length on emergence, of a light yellow colour; the head shining black with a yellow clypeus; the caudal horn, forked at tip, is at first yellowish, but soon becomes black, no particular mark- ing present, but a reddish stripe extends along the region of the dorsal vessel, and the course of the spiracles is marked by an orange-red line (Studies in Theory of Descent, pl. vi. fig. 53 A-B); aS soon as the young larva is filled with food it acquires a greenish streak. The first moult occurs after 4 days. Second instar: Immediately after the first moult there is still an absence of distinct markings, with the exception of a greenish-white spiracular line; in the course of * Buckler and Weismann both agree (see pp. 283-284 and 285-286) in giving the larva of this species only 5 instars, 286 BRITISH LEPIDOPTERA. some hours the original light green ground-colour becomes darker, and, at the same time, a sharp, greenish-white subdorsal line appears, together with a parallel supraspiracular line; the dorsal line is absent; the head is light green, with two narrow blackish-brown lines surrounding the clypeus; the horn and thoracic legs black; claspers reddish-green; length r2mm.-13mm. (fig. 54). The second moult takes place after another 4 days. Third instar: Neither colour nor marking is affected by the second moult; only the horn, now no longer forked *, becomes brownish with a black tip. The caterpillars are now, as before, admirably adapted to the pine-needles, on which they feed by day, and from which they can only be distinguished with difficulty. Fourth instar: The third inoult also brings no essential change, the ground-colour and marking remain the same, only the spiracles, which were formerly dull yellowish, are now of a vivid brick-red. The horn becomes yellowish-red at the base. /ifth instar: The marking is only completely changed in the fifth and last stage. A broad reddish-brown dorsal line replaces the subdorsal, more or less completely. The supraspiracular line also becomes broken up into numerous short Jengths, whilst the green ground-colour in some specimens becomes more or less replaced by a_ brownish shade extending from the back to the sides. Horn black, the upper part of the 1st segment with a corneous plate, similar to that of the Dezlephila larve. The entire change of the marking from the 4th to the 5th stage depends upon the fact that the young larvae resemble the needles of the pine, whilst the adults are adapted to the branches. The ontogeny of this species makes us acquainted with three different forms of marking: (1) Simple coloration without marking. (2) A marking composed of three pairs of parallel longitudinal lines. (3) A complicated marking, arising from the breaking up of the last and the addition of a darker dorsal line (Weismann). Cocoon.—The larve go some little distance below the surface of the earth and form an earthen cocoon in which to pupate. They prefer to go into the ground near the trunk of a tree to form their puparia (Bartel). The pupz are readily found at the roots of pines under the moss (Ratzeburg). The cocoons are made at the foot of trees of Pinus sylvestris, at a depth of about 3ins., in the Namur district (Lambillion). Pupa.—This pupa is not easily distinguishable, except by its size, from that of Sphinx ligustri, and, as a matter of fact, I had a pupa of S. Zgustr?, correctly named, which happened to be a and unreliable. Bacot notes having two adult larve, both showing the forked character of the horn, which was much more distinct, however, in the 4th instar. HYLOICUS PINASTRI. 287 myself that my first impression, that some mistake had occurred, was erroneous. The most definite difference is in the sculpturing of the abdominal segments—in /7Z. puvast7t wrinkling almost throughout, whilst, in S. “gustri, pitting is always present, and even predominates. This gives the pupa a less polished, rather dull, look, whilst on closer examination, the sculpturing is found to differ in a good many details. The lateral spines of the anal spike also are less well-developed and nearer the extremity. The first femur, which is hardly represented, and is occasionally absent, in S. /zgustri, is quite invisible in 4. penastri. The following measurements of the pupa appear to be the most important : DISTANCE WEASURENBNTS At i, (S| ure EXTREMITY TO Base of proboscis and anterior margin of prothorax .. o-6mm. 3°0mm. 4-omm.

The measurements do not demonstrate, however, the fact that the flattening is greatest dorsally, especially over the 3rd and 4th abdominal segments, and that there is ventral prominence at the same region, giving an appreciable trace of the S-curve, occurring in Sphingid (sews. restr.) pup. This flattening curvature, with the wrinkled sculpturing, shows that this pupa is more specially Sphingid than is that of Ee ligustrt. The extreme anterior of the pupa is the head, about + back from the base of maxillz to the prothorax. The eyes have the convexity about 30° from directly forwards. The middle (transverse) plane of the pupa would be very httle in front of the anterior border of the prothorax, which slopes forwards; if the maxilla-case (or -horn) were absent, the most forward point of the pupa would be little dorsal to the ventral surface. The sutures marking out the labrum can be made out, but the rest of the head is well wrinkled, but with no very definite features, except a trace of dorsal suture (the headpiece being ventral, this is rather incorrect, but it is in line with suture on prothorax) and the glazed eye, which has the 288 BRITISH LEPIDOPTERA. usual glazed line, with smoother piece (broader inside) on each side of it, with radiating wrinkles. The maxilla-case is nearly 5mm. long, with 4mm. free, but is very closely appressed to the pupa so that it is straight and no light is seen between it and the pupa. It has a deep median suture, the halves strongly wrinkled transversely and the wrinkles minutely subwrinkled. The rest of the maxille and the legs are very minutely wrinkled or rather with very flat tubercles, arranged as if they were the remains of nearly obsolete fine wrinklings. The antennz are divided into segments, each segment subdivided by one transverse and one or two obliquely longitudinal impressed lines. The prothorax has a longitudinal dorsal suture, and the well-marked wrinklings, though irregular, have some tendency to be arranged concentrically to the middle of each lateral half. The mesothorax has an indication of an obsolete mediodorsal suture. There is the suture-like smoothness at about the line of the inner edge of the patagia. ‘The sculpture inside these is transverse wrinkling, anastomosing and_ tending to have a central focus in the median line, not far from the posterior border of segment. The wing-bases are prominent with sculpture that is rather irregularly tubercular than wrinkled but with no definite tubercles or points. The wings are finely wrinkled, coarser, and with a transverse arrangement basally, finer, and with longi- tudinal lines more numerous, towards hind margin ; the nervures can be made out, but not with facility; Poulton’s line is obvious as a fine line, free from sculpture and with the margin beyond (about o-3mm. wide) with regular longitudinal lines; it is also visible on the slip of hindwing which, yielding to the rst abdominal spiracle (of znd segment), disappears opposite the znd. The maxille and wing-apices terminate very accurately at the margin of the 4th segment. The metathorax is narrow, has two small transverse ridges on each side of the middle line, and is elsewhere wrinkled in a fairly regular pattern. The abdominal segments are finely but boldly wrinkled. The 5th abdominal segment presents dorsally, along its anterior margin, in the hollows of the wrinkles, points that have some resemblance to pits. These become more definite on the 6th and 7th, and are pits, pure and simple, on the 8th, though wrinkling rather than pits still holds the posterior portion of that segment; 9 is entirely pitted. This transition from wrinkling to pitting, passing backwards along the segments, is more advanced ventrally, though even here wrinkling holds place towards the posterior margin even of the 7th segment. Subsegmentation is not well marked ; dorsally, a narrow anterior subsegment may be seen on the 2nd abdominal and following segments, but the intersegmental subsegment is in doubtful evidence even in the most favoured position for detecting it, 7zz, behind the 3rd and 4th spiracles. In one or two specimens, on the znd and 3rd abdominal segments, the dorsum is divided into four tolerably equal subsegments, and, on the 3rd segment, further subdivisions may sometimes be made out, as if into 5, the first and last being widest and the 4th perhaps even further subdivided. In some specimens no subsegmentation can be seen. The scars of prolegs vary a good deal, usually each is a slight depression with a small smooth area as its posterior margin towards which sculpturing radiates and dies out, In one specimen the whole HYLOICUS PINASTRI. 289 area was raised, with a definite sulcus round its anterior border. Few specimens are quite without, and one or two have, very markedly, a deep little pit at the outer margin of the propedal scar, this has nothing to do with the scar, as, in the specimens which show it best, it also occurs on segment 7. It probably represents the triple- haired tubercles that occur here in the larva. The scar of the larval horn may be merely a small smooth area, more usually it is a definite little rounded raised protuberance smoother than its surroundings and with a slight hollow behind it. The anal spike is 2‘omm. to 2°6mm. long, and about 1°5mm. in diameter at the base, not narrowing so rapidly towards the base as apically, but varying much in this as in other particulars. An odd specimen is found with the spike almost identical with that of S. /égustr¢ (which varies less), but most have the lateral points nearer the end and smaller, others have them nearly obsolete, one or two have them larger, or with several irregularly placed; the end is bifid, basally it is wrinkled coarsely, as coarseness goes in this pupa. Anterior to the spiracles and thence dorsally for a length of about 4:omm., there is, on the anterior margin of segments 5, 6 and 7, a quite smooth surface margined by rather sharp raised ridges, the posterior being the Sphingid prespiracular flange, and a third slight ridge can be barely seen, deep in the incision, when the segment is well bent to the other side. ‘The anal scar is a longitudinal impression about 1°4mm. in length, often narrow in front, wide behind, and, usually, with raised margins. The male tubercles are two raised smooth eminences with a depression between them and enclosed by a circular (or nearly so, it is usually a little wider transversely) groove. They occupy nearly the whole width, but rather encroach on the posterior, avoiding the anterior, margin of the gth segment. The incision in front, however, is smoothed out to about the same degree as that behind. In the female, these incisions are still more smoothed out, but nave little of the usual appearance of the posterior segments having been drawn forwards into the anterior. There is a round pore in the middle of the 8th segment, but with the appearance of really belonging to the 9th, and another half-way between this and the anterior margin of the segment, the latter being continued as a narrow slit to the anterior margin of the segment. In another specimen (one only) both these pores are united in a deep, wide impression, extending from the middle of the segment to its anterior border. In another, both are very distinct and separated ; the anterior one is in the middle of the segment, the other behind it, the slit extending to the anterior margin of the segment is a mere faint line and does not extend to the pore. In another, the two pores are conjoined, but distinct from the faint line extending to the anterior margin of the segment. ‘The first and third of these varieties are the more numerous. The microscopic aspect of the pupa shows the pits to be pale with shading radiating from the centre to the irregular margins. In showing the transition from pits to wrinkling, the 8th abdominal segment is most instructive. From the pits radiate, generally laterally, one, two, or more of the fine dendritic lines that mark the bottoms of the sulci between the wrinklings, and, when they are numerous, present a_ similar pattern to nerve cells with their dendritic branchings. MHairs are A 290 BRITISH LEPIDOPTERA. very difficult to find; several, very short and baton-shaped, exist in the narrow area between the two most forward ridges of the prespiracular flanges. As regards these flanges, the spiracles con- cerned appear to be pushed back by the flange, having the wrinkling behind it thickened as if pushed together and puckered up. The spiracles have special marginal’ fringes, the margin of the first (external false) appears to be smooth and without spicules. The labrum is well marked out, and has a lower margin with three convexities, and beside it are two separate chitinous patches that are very probably the mandibles (Chapman). Long and _ slender compared with the pupze of Amorphids, red-brown in colour, the dorsum rather darker, the skin somewhat rugose, the dorsal area wrinkled transversely. The head prominent, the maxille partly enclosed in a separate case almost ‘25in. long, closely appressed to venter; two maxillary filaments, however, are placed medio- ventraliy, and terminate at the apices of the wines aueume glazed-eye forms a small, somewhat rugose, lunular structure; the two pairs of legs are distinctly marked; the antenne reach two-thirds towards apex of wing, segmented, each segment with a tiny knob, the wings with raised nervures. The prothorax prominent, the mesothorax large, and swelling out at the wing- bases; the prothoracic spiracle at the junction of the pro- and mesothorax, and in contact with the antenna at its lower point, blackish in colour; the metathorax narrow. ‘The abdominal seg- ments increasing in size to 4, and then decreasing to anus ; movable incisions between 4-5, 5-6, 6-7, the incisions much _ better developed laterally than dorsally; the centre of the dorsum of 4, 5, 6 and 7 slightly depressed; abdominal spiracles narrow linear slips with moderately-prominent margins, and placed well forward on each segment; ventrally, abdominal segments 5 and 6 show scars of larval prolegs; sexual organs distinct ; the cremastral horn slender with bifid tip (Tutt. March 28th, 1897). 4omm. in length, cylindrical, with the tongue-case just like that of the pupa of Sphinx ligustri, but only 5mm. long. The abdomen tapers to the anal seg- ment. The rough anal spike longer and more slender than in S, ligustri, with two pairs of short spines in its sides, and a pair at the tip. The pupa-skin is granulated, and dark red-brown in colour (Hellins). PUPAL PERIOD.—Richenau, who has made observations on this species in the Mombach pine forests, states that there is there a complete second and a partial third brood, with correspondingly short pupal periods (Rossler), but one suspects that such appearances are rare, and that the ordinary pupal period extends from August- September to the following May-June. Schmid notes that the pupal stage sometimes extends over two winters, and Hellins mentions (Buckler’s Larvae, &c., ii., p. 113) a pupa which remained two winters * in this state. * Buckler notes (Larvae, &c., il., p. 27) that he reared these larvze in 1882, and that they pupated in September, 1882; Hellins states (uc. cit., p. 113) that he bred moths from these pupze from June 24th-30th, 1884, and one, which remained two winters in the pupal state on June 29th, 1885. This would make two and three years respectively ; possibly an error by Hellins as to the year in which the specimens emerged, HYLOICUS PINASTRI, 291 FoopPLaNts.—Pinus sylvestris (Lambillion), P. Jaricis, Abzes alba, Picea excelsa, Larix decidua (Bartel), Pinus strobus (Ochsenheimer), Abies picea, A. pectinata (Snellen), Pinus maritima (Trimoulet), P. pinaster (Godart), Pinus abies (Heinemann), Cedrus libani, Cedrus deodara (Waller). , PaRASITES.—Amblyteles proteus, Christ (Holmgren), J/chneumon pisorius, Linn. (Hartig). Hapirs.—The imagines have much the same habits as Sphinx ligustri, pairing readily in the evening and remaining 7” cof. all the next day, separating at dusk, when the @ almost directly commences oviposition (Head). The imagines are attracted to flowers in the evening, at dusk, preferring honeysuckle over arbours in villages near pine forests (Ratzeburg), at flowers, preferring Saponaria officinalis, flying from before dusk until completely dark, for about an hour, at Biedenkopf (Ruhl), at flowers of honeysuckle at Aldeburgh (Hele), at flowers of Sapfonaria at Modena (Fiori). It comes occasionally to light, ¢g., not common in June, 1892, but somewhat abundant from May 3rd, 1893, at electric light at Berne (Hiltbold), also at Aigle, at electric light, July 3rd- Ath, 1898, from 9.15-10.20 p.m. (Lowe), very abundant at electric light in July, 1896, at Aix-les-Bains (Agassiz). The species comes to sugar in Saxon Upper Lusatia (Schutze), and at Dresden (Steinert). In the daytime it is very sluggish, sits on the trunks of firtrees near Woodbridge, and will not fly even when moved off the trunk, but drops into a box held underneath (Thellusson), about 40 were taken in 1882, at Aldeburgh, being captured at rest on the trunks of Scotch firs, from about 4ft.-14ft. from the ground in every aspect, apparently without regard to wind or weather (Hele); occurs commonly on the pine trunks about Namur at a height of about 3ft. from the ground (Lambillion) ; is to be found at rest during the second week of June, Ig00, on the Sacro Monte, sitting on the pine-trunks at a short distance from the ground, but the specimens are very difficult to see, as, in colour, they assimilate marvellously with the rough lichen stained bark (Lowe). Treitschke mentions (Die Schmett., x., i, pp. 137-138) the pairing of a g of Smerinthus ocellata witha ? of this species, whilst Bartel notes (Pal. Gross-Schmett., \i., p. 50) the pairing ofa g A. pinastriwith a 2 Mimas tiliae. Hapitat.—Inhabits the pinewoods throughout Europe, Asia, and probably North America, occurring abundantly in many localities, and spreading for some distance up the mountains. In the Hartz mountains it reaches the moor districts, probably spreading there from the lower forest region (Hoffmann); but, although so widely distributed, it usually only occurs somewhat sparingly in most of the old pine forests of Europe, it is, however, not confined to these, being also found in young plantations, as well as in pine thickets that have long been isolated (Ratzeburg); at Arcachon it occurs in the pine-forest that has been planted on the Landes, the species of pine on which it occurs being Przus maritima, whilst, in Spain, it occurs throughout the old pine-forests of the Albarracin district to an elevation of at least 5oooft. (Chapman); it is common on the Sacro Monte, a park consisting chiefly of giant pines (Lowe). SUMMARISED HISTORY OF HYLOICUS PINASTRI AS A BRITISH INsEcT.—Donovan, as far back as 1800, refers to a “traditionary 292 BRITISH LEPIDOPTERA. report” of AH. pimastri being British, the locality whence the speci- mens came being vaguely given as “Scotland.” He further notes that, “as it is generally admitted on this authority to a place in the cabinets of English insects,’ he cannot refrain from giving it a place in his Watural History of British Insects. Waworth, in 1803, mentions that it occurs “in thé-month of June,” “ands taateetees to be found on the trunks of pines, “and is taken near London very rarely.” Stephens, in 1828, is more exact, and mentions “one specimen taken in June, near Colney Hatch wood, about 30 years ago, and a second in the neighbourhood of Esher.” This takes us back to the time of Haworth, and affords a clue as to the amount of his (Haworth’s) information about the species. Stephens, however, adds that, “at Rivelston Wood, near Edinburgh, one specimen was taken by Dr. Leach, and several by Mr. Wilson, of the College.” In 1842, Marshall states (£774, 1., p. 231) that he saw a living specimen in Cumberland in 1827 or 1828. At the February, 1860, meeting of the Entomological Society of London (Zo0l., p. 6940), Sealey exhibited a specimen which was stated to have been taken in a firwood near Romsey, in June, 1859, by a Mr. Morris, but the latter’s brother, who had added Swiss specimens to the collection, said that he remembered taking the example himself in his own garden (see Zz¢. Wh. Int., vil., p. 193). We next find records of single specimens said to have been taken 6 years previously, one by Miss Bicknell at Hinton St. George, and now in the Museum at Crewkerne* (Spiller, £77, vi., p. 103), and the other in(? ) Devonshire*, captured 11 years previously, by Miss Jones (Purdue, Zoc. czt., p. 127), the latter example reported to have been taken in September, 1861, a remarkable date for the species. Higgins exhibited, at the meeting of the Entomological Society of London, November 17th, 1873 (774. vil., p. 46), an example said to have been captured at Harwich in June, 1872, but, as it was shown at the same time as two A7/yles euphorbiae, also stated to have been bred from the same place, the record need not be considered, and then we learn that Waller took one at Waldringfield in August,1876 (Z.JZJ1Z,, XIV.,/p. 130), that Frere had one emerge on August (jthmmoge: from a pupa, found near Wickham Market (£7/., x., 210), that Long captured another at @uddenham, on June) 25ungeeage (Stainton, £.17.M/,, xiv., p. 67, 136), and Waller a third in August, 1877, also at Waldringfield (/oc. cit., xiv., p. 136), whilst Mrs. Carpenter obtained a larva at Leiston in 1880, and Bloomfield (Zep. Suffolk, p. 8) records two .for 1378, at Waldringfield (see 2.A7 75 xvi p. 93), whilst yet another was taken by Waller, on July 14th, 1879, at the same place (#.47.47, xvi., p. 93), and Bloomfield (Zep Suffolk, p. 8) notes another at Saxmundham in 1879. On July 2end, 1881, and July 23rd, 1882, Ager recorded two examples at Ipswich (Ent, xiv., p. 210; xXvi., p. 187), and Battiscombe gives a record for Herefordshire in September, 1881 (doc. ci?., xiv., p. 255), almost certainly a blunder. Previously to these records, Carrington had noted (Lntom., x., p. 6) that he had received letters stating that one had been “bred in the eastern counties” and that another had “ graced * Both these examples are reputed to have been taken by ladies in gardens. One suspects a want of care in keeping really British captures separate from Continental insects, since neither was recorded as British until several years after their reputed capture. HVLOICUS PINASTRI. 2938 a baker’s pump at Deal.” In 1882, Carrington further publishes (ew, XV. p. 210/;two letters received from cofrespondents whom he obviously suspected of introducing the species for sale purposes into the Suffolk district, but Cooper wrote a _ note (f£nt., xix., pp. 14-15) supporting the authenticity of the Suffolk Specimens, stating that Hele had taken imagines and larve at Aldeburgh in 1885, whilst Hele himself (Bloomfield’s Lepzdoptera of Suffolk,’ p. 8) says that he took one in July, 1881, and, in the following year, about 40, in July and August. In this year, Coverdale found larve in the same district and bred imagines, which are in our possession. Cooper’s note brought a letter from Edwards (Zy7¢, xix., p. 64), stating that a larva taken in the Island of Mull in September, 1860, near Achnaeroish, produced an imago on July 24th, 1861, a second larva being taken in the Same wood in September, 1861, but this died. Rendlesham obtained imagines, from which ova were obtained, in 1892 (Ext. Rec., iii., p. 226), and Walsingham exhibited larve, received from Rendlesham, at the meeting of the Ent. Soc. of London, held on October 5th, 1892 (ie, Pp» 245). - whellusson states (/oc. ciz., Vil., p. 131) that he first found the species in August, 1891, taking 14 specimens and leaving many worn ones on the trees at Woodbridge, but the context shows that this statement refers to the 1892 captures just men- tioned. He says that none were seen in 1892, an obvious error, but specimens were again captured in 1893, 1894, 1895, when many imagines, larve, and dug pupz were found. Thus three larve were found August and September, 1893 at Waldringfield, on August 25th, 27th, and September 6th, two imagines appearing in June, 1894 (Zuz., xxvii., p. 246), whilst, on June 23rd, 1895, two imagines were taken, and 15 others are reported as having been captured at later dates, whilst on August znd, 1895, some 100 larvee were feeding (/yvz., xxvill., pp. 232, 257), and the species seemed to have become firmly rooted in the county. But disil- lusionment came, and Cambridge (£7. fec., vil, p. 218) did a real service to science, as well as to all students of the distribution of Our native fauna; when he explained how a direct and apparently successful attempt had been made to acclimatise the species in Suffolk, and those of us who possess Suffolk caught and_ Suffolk bred examples no doubt owe our specimens indirectly to these introductions. Why those who introduced the species into Suffolk did not notify the same to the entomological magazines it is difficult to say, but we do not here propose to discuss the subject further. The only other records that we have observed are: In 1884, Watkins (a dealer) states that he took a specimen on May 26th, off the palings of West Wickham Wood (£.4/.J/, xx1., p. 34), whilst Godwin records a larva in the early part of September, 1887, near Wimbledon, which produced an imago on July 16th, 1888 (ei 23N., Pp. 159); 1 ro05, Gummer records an example taken at Salisbury by his sister (Z¢., xxviil., p. 312), and Abbott is recorded (£/., xxix., p. 70), as exhibiting, in 1896, Sussex examples, and remarking that in that county the species had been taken in numbers recently—an obvious error! Tarbat in June, 1897, found an imago in a breeding-cage, without knowing certainly whence he obtained the pupa (Z7+¢., xxx., p. 222), whilst Douglas (£77., xxxill., p. 250) notified 994, BRITISH LEPIDOPTERA. the capture of agon July 29th, 1900, on an oak trunk at Southwold (the last record of the species having been taken at large in Suffolk) ; an example was recorded in 1902, by Johns (£77. Rec., xiv., p. 248) as captured at Winchesteron June 30th. One suspects that these records are largely due to errors, incidental to and inseparable from the attempted study of a scientific subject by a large number of poorly equipped students. . A few may. be due to “escapes,” but theremismmmmens indirect evidence furnished, not only pointing to grave doubts as to whether the species ever was sedentary in our Islands, but also suggesting, from the gradual decadence of the progeny resulting from the Suffolk introductions, that there is no real natural tendency for the species to become acclimatised and take up a permanent residence here. TIME OF APPEARANCE.— Very little, if any, evidence that the species is double-brooded, beyond the statement of Reichenau that the species has two complete. and a third incomplete brood in the pine forests at Mombach (¢este Rossler), is to be found; Fritsch certainly gives May 4th-July 6th for Austro-Hungary, with a few dates in late July and in August, chiefly at Salzburg, that might, he thinks, possibly belong to a second brood, whilst May-June and again in August-September are given for Lom- bardy and May and September are given for Tuscany. But there is no doubt that, even where the species is undoubtedly single- brooded, emergences, are often spread over a long “timenmia Germany the species is recorded from May to August—in July at Schwerin, May-August at Eutin, June-July at Cassel and Kempten, in May-June at Brunswick, Alsace and Frankfort-on-Main, beginning of July in the Oberharz, May-August at Leipzig, Thuringia and Baden, and until September at Wiesbaden; May-July in Switzerland, ~ May-June in Hungary, but continuing into July at Funfkirchen, end of June and commencement of July in Roumania. Bartel notes June at Boulogne (certainly near enough to the British Islands), Caradja gives August in the Loire-Inférieure, &c., May 25th-August 28th at Biedenkopf (Ruhl), April 16th to the end of May, 1862, in Nassau (Rossler), emerges rarely in April, generally from May to July in Germany (Bartel), in July, at Aix-les-Bains (Agassiz), in June in the Kasan district (Eversmann), July 19th, 1880, at Gstein (Hor- muzaki), bred June 25th-June 30th, 1884, and June 2gth, 1885, from pupz, the ova which produced these having been obtained from Leipzig (Hellins), imagines June-August—June 12th, July 15th, 28th, August 5th at Nohant, August 15th at Planet (Sand), from mid-May to the middle of July in the Inn valleys, often common, captures were made on May aist-24th, 1896, near Riesenhof, June znd-3rd at Postlingberg, June 28th at Buchenau (Himsl), in the Netherlands, imagines are to be found continuously from June to August (Snellen), but in Belgium the imagines are usually taken in June and July (Lambillion), May 12th-June 16th, 1goo, common at Orta Novarese (Lowe), bred June 2nd, 1902, and following days at Dorking, from foreign ova (Oldaker), the earliest date at Woodbridge in those years in which the species was obtained in Suffolk, was on June 8th, the species continuing to emerge until the end of July or early August (Thellusson), July z9th, 1g00, at rest at Southwold (Douglas). The rest of the recorded dates for Britain may be gathered from the preceding paragraph. HYLOICUS PINASTRi. 295 LOCALITIES.—This species appears to have no real locus standi in the British fauna.

Books written by J. W. TUTT, F.E.S, [All orders for which should be sent direct to A. HOLDER, 41, WISTERIA RoapD, LEWISHAM, S.E.] Natural History of the British Lepidoptera. (A textbook for Students and Collectors.) 4 volumes. Price £1 each volume, net. Demy 8vo., thick, strongly bound in Cloth, . Volume I contains 560 pp. + vi pp. Volume II, 584 pp. + viii pp. Volume IIT, 558 pp. + xi. Volume IV, 535 pp. + xvii pp. This is one of the most important works ever offered to lepidopterists. The British fauna is merely taken as a groundwork for the thorough revision of each superfamily treated, and the work thus becomes of first importance to all lepidopterists in the world—systematists, biologists, synonymists, phenologists, &c. ‘‘ This important work puts all others of the kind into the shade. It deserves our full attention and recognition, and the opportunity for its study is not to be missed by any students of European Lepidoptera to whom it is no less valuable than the Briton” (Berl. Ent. Zeitschrift, Dec. 1902). The British Noctuz and their Varieties. Complete in 4 volumes. 28/- per set, net. Demy 8vo., strongly bound in Cloth, The four volumes comprise the most complete textbook ever issued on the Noctuides. The work contains critical notes on the synonymy, and gives the original type ‘description (or description of the original figure) of every British species, the type description of every known variety (European, African, Asiatic, or American) of these species, tabulated diagnoses and short descriptions, of the various phases of variation of the more polymorphic species; all the data known concerning the rare and reputed British species. Complete notes on the lines of development of the general variation observed in the various families and genera. The geographical range of the various species and their varieties, as well as special notes by lepidopterists who have paid particular attention to certain species. Each volume has an extended introduction. That to Vol. I deals with ‘‘ General variation and its cause ’’—with a detailed account of the action of natural selection in producing melanism, albinism, &c. That to Vol. II deals with “ The evolution and genetic sequence ol insect colours,’’ the most complete review of the subject published. That to Vol. III deals with ‘‘ Secondary Sexual Characters in Lepidoptera,”’ explain- ing, so far as is known, a consideration of the organs (and their functions) included in the term. That to Vol. IV deals with ‘‘ The classification of the Noctuz,’’ with a comparison of the Nearctic and Palzearctic Noctuides. The first subscription list comprised some 200 of our leading British lepidop- terists, and up to the present time some 500 complete sets of the work have been sold. The treatise is invaluable to all working collectors who want the latest infor- mation on this group, and contains large quantities of material collected from foreign magazines and the works of old British authors’ arranged in connection with each species, and not to be found in any other published work. Melanism and Melanochroism in British Lepidoptera. (Demy 8vo., bound in Cloth. Price 5/-). Deals exhaustively with all the views brought forward by scientists to account for the forms of melanism and melanochroism; contains full data respecting the distri- bution of melanic forms in Britain, and theories to account for their origin ; the special value of ‘‘ Natural selection,”’ ‘‘ environment,”’ ‘‘ heredity,”’ ‘‘ disease,”’ ‘‘ temperature,”’ &c., in particular cases. Lord Walsingham, in his Presidential address to the Fellows of the Entomological Society of London, says, ‘‘.An especially interesting line of enquiry as connected with the use and value of colour in insects is that which has been followed up in Mr. TutTt?’s series of papers on ‘‘ Melanism and Melanochroism.” British Butterflies. (Illustrated. Crown 8vo., Cloth, Gilt. Price 5/-). This book consists of 476 pages, contains 10 full-page illustrations, and 45 wood- cuts. There are figures of every British butterfly. Sometimes three or four figures of the same butterfly to illustrate the two sexes, underside and variation are given. The full-page illustrations and most of the wood-cuts have been drawn by the well-known entomological artist, Mr. W. A. Pearce. Each British butterfly is described under the following heads :—(1) Synonymy, (2) Imago. (3) Variations, with summarised diagnoses of all described forms, British and Continental. (4) Egg. (5) Larva. (6) Pupa. (7) Time of appearance. (8) Habitat and Distribution. Besides these, there are extended remarks on each of the Tribes, Subfamilies, Families, Divisions and Superfamilies. The descriptions of the ** Larvee”’ and ‘‘ Pupz”’ are mostly original. There are 282 aberrations and varieties diagnosed, of which 111 are described for the first time. The varieties and aberrations found in every part of the world are dealt with. At the end of each chapter is a brief summary giving the following information, in tabular form, for each species:—I. Date for finding (1) the ovum, (2) the larva, (3) the pupa, (4) the imago. II. The Method of Pupation. III. Food-plants. The preliminary chapters consist of a series on the structure of the Egg, Larva, Pupa, &c.; also others on practical work—Collecting, Pinning, Setting, Storing, Labelling, &c. Practical Hints for the Field Lepidopterist. Complete in two parts. Price 12/- (6/- each part) net. (INTERLEAVED FOR THE COLLECTOR’S OWN NOTES). This is one of the most useful, accurate, and important books ever offered to the field-lepidopterist, and will save him time, trouble and expense in prosecuting his work. In each part are some one thousand two hundred and fifty practical hints, telling the lepidopterist, how, when and where to work for the most desirable species. No lepidopterist can afford to be without a copy of this book. To the younger collector it offers a mass of information that he could not hope to accumulate by himself in very many years of field work. To all it must remain one of the most necessary books ever published for the use of field-lepidopterists. The contents are divided into the following chapters: (1) January, February, and early March ; (2) late March and April; (3) May; (4) June; (5) July; (6) August; (7) September; (8) October; (9) November and December. Each chapter of Part I opens with a general review of the field-work that can be done in the period indicated, and this is followed by a classified list of the “‘Hints’’ available for the period. In Part II each chapter also contains a preliminary summary of the work to be done during each month, but, as the method of work in the field was more particularly dealt with in Part I, these summaries in Part II deal more especially with the points raised by the various methods of Rearing larve in confinement, Sleeving, Breeding-cages, Food, and Feeding larve; Obtaining eggs in confinement from butterflies and moths ; Special treatment of pupz ; Keeping pupze through winter ; Special treatment of certain larve in order to obtain pupz; Sugaring ; Assembling ; Forcing, and a host of similar important topics to the entomologist. Quite new ground is broken and there is no repetition. The whole of the material thus grouped offers a great mass of exact, useful and reliable information, bearing on the work of the lepidopterist in the field, telling him exactly what to do and how to do it in the fewest possible words and in the least possible space. Such information could only be gathered by the individual worker as the result of many years’ cbservation and by reference to many books in which the facts are buried amongst a mass of other entomological detail. Lepidopterists, experienced and inexperienced, will find in this book much infor- mation that will suggest quite new lines of work in their collecting, and enable them to find, in close proximity to their homes, species which they had never suspected to be in their vicinity, and the saving of time and trouble will thus be enormous. : The book has been interleaved, so that collectors can add therein their own notes, dates, &c. Reference has been made easy, the notes for each month being classed under the superfamily heads to which they belong, e.g., those for June come under — Tineina (unclassified), Tineides, Adelides, Plutellides, Elachistides, Gracillariides, Argyresthiides, Coleophorides, Lithocolletides, Nepticulides, Tort- ricides, Pyraloides, Crambides, Pyralides, Drepanulides, Cymatophorides, Brephides, Geometrides, Pterophorides, Sesiides, Zeuzerides, Cochlidides, Psychides, Anthro- cerides, Lachneides, Sphingides, Deltoides, Lymantriides, Nycteolides, Notodontides, Noctuides, Arctiides and Papilionides. These also will give an idea of the range covered by the notes. ; The Migration and Dispersal of Insects, Demy 8vo; 132 pp. Price 5/- net. This book, the only one published on this interesting subject, is of first importance to all students of geographical distribution, and contains the following chapters: 1, General considerations. 2, Migration of Coccids and Aphides. 3, Orthoptera. 4, Odonata. 5, Lepidoptera. 6, Coleoptera. 7, Diptera. 8, Social insects— Hymenoptera, Termites. 9, Final considerations. The vast amount of literature overhauled for the facts, the great labour spent in the arrangement of so much hitherto scattered material, the summary of almost everything that is available that has been written on this interesting subject, have resulted in the collection, in a comparatively small space, of facts that are only otherwise to be found scattered through the periodicals and other publications of the last century, and from rare poe that can only be occasionally purchased at a high price or consulted in the ational library ; whilst a large number of hitherto unpublished facts, and the generalisations bearing on the subjects as afforded by the evidence at disposal, make the work of the highest value to all students of the subject treated.
