THE LIBRARY OF THE UNIVERSITY OF CALIFORNIA DAVIS GIFT OF W. HARRY LANGE Q-U*. A HANDBOOK OF BRITISH LEPIDOPTERA A HANDBOOK OF BRITISH LEPIDOPTERA BY EDWARD MEYRICK, B.A., F.Z.S., F.E.S. ASSISTANT MASTER AT MAIILBOROUGH COLLEGE ILonfcon MACMILLAN AND CO. AND NEW YORK 1895 PREFACE THIRTY -six years have elapsed since the publication of Stainton's Manual of British Butterflies and Moths, and no complete work on the same subject has appeared in the interval. Useful as the Manual has been, it affords no satisfactory information on structural distinctions except in the Tineina, where the author was relying on his own observations ; the nearly valueless characters assigned to the other groups being simply copied from other writers, and mainly from the pseudo-scientific work of Guene'e. As Darwin's Origin of Species, which effected a revolution in the principles of classification, was first published at the end of the same year, it is perhaps not very creditable to British Lepidopterists that so little pro- gress should have been made meanwhile in this direction. This work is designed to enable any student of British Lepidoptera to identify his specimens with accuracy, and also to acquire such general knowledge of their structure and affinities as ought to be possessed by every worker before proceeding to more special investigations. I hope however that, as an elementary guide to the classification of the Lrpidoptera, it may also prove serviceable to those valued correspondents in many lands who have given me so much assistance in other entomological labours. The structural characters are in every instance drawn up from my own observations. The system of classifica- tion, though now fully published for the first time, is not vi BRITISH LEPIDOPTERA based on the British species only, but is the outcome of my study of the Lepidoptera of the whole world. The specific descriptions are usually made from British ex- amples, but in cases where a species is rare in Britain and there is no reason to suppose that the British form differs from the Continental, I have not hesitated to avail myself of good series of the latter. Larval descriptions require to be made from living specimens, and it would have been impossible to hope to see most of the species within a limited time ; I have therefore drawn up these to the best of my judgment from a comparison of the most trustworthy published descriptions, though they are often amazingly contradictory. On disputed points I have simply stated my conclu- sions, based on the best available evidence, but without discussion. Published localities or statements which are discredited are omitted without comment ; such omissions may be assumed to be intentional. The general exposi- tion of principles in the Introduction must be accepted in place of the explanation of particular instances. I desire to gratefully acknowledge the assistance rendered by Miss M. Kiniber, E.E.S., in collecting and tabulating for me a vast number of records of geo- graphical distribution obtained from the various entomo- logical periodicals and published local lists, as well as others furnished to her by reliable private correspondents.

" INTRODUCTION THE object of the explanations given in. this portion of the present work is solely to make the subsequent portion intelli- gible, and no subject is discussed in greater detail than is necessaiy for that purpose. Hence no account is given of the internal organs belonging to the digestive, nervous, and mus- cular systems, which, so far as studied, have not yet been found to present characters available for use in classification. The Lepidoptera are amongst those insects in which the life of the organism, after leaving the egg, is marked by a series of well-defined changes in structure and habits. In the case of the Lepidoptera three separate stages (besides the egg) are constituted, each with its appropriate function ; (1) the larva (or caterpillar), whose function is growth ; (2) the pupa (or chrysalis), whose function is maturation ; and (3) the imago (or perfect insect), whose function is reproduction. Structure of Imago. All the details of structure hereafter mentioned can be observed with a simple lens of moderate power ; but a strong lens (such as a platyscopic or Coddington) will sometimes be found useful. In the examination of obscure details the proper management of the light is essential ; if the illumination of the object is satisfactory, the magnifying power of the lens is a secondary consideration. A Lepidopterous insect is regarded as normally composed of thirteen segments, of which one (really consisting of several segments fused together) forms the head, three the thorax, and the remaining nine the abdomen, though one or two terminal segments of the abdomen are often much modified and little recognisable ; four wings and six legs are usually present as paired appendages of the thorax, but in certain cases are not developed. INTRODUCTION The front part of the head is called the face, the upper part the crown ; sometimes there is a distinct raised transverse fillet between the antennae; the sides are mainly occupied by the large eyes, and the lower part by the mouth-organs ; the back, forming the junction with the thorax, is covered by a collar of scales. The organs attached to the head are all paired ; these are the eyes, ocelli, antennae, maxillae (combined to form the proboscis), mandibles, maxillary palpi, and labial palpi. Occasionally the chitinous substance of the head is enlarged to form a pro- tuberance, which is of the nature of an excrescence and not a true organ. The eyes are compound, being made up of a very large number of simple lenses, the whole having a more or less hemi- spherical surface, which is sometimes furnished with erect hairs, but usually glabrous. The ocelli are small simple lenses, placed on the crown close behind the eyes ; they are rarely conspicuous, often partially or quite hidden in scales, or entirely absent ; their function is not understood, but as they are so frequently obsolete, they can hardly be of much importance. They are often erroneously stated to be absent when only concealed ; and in general not much stress should be laid on them for purposes of classifi- cation. The antennae are sense-organs, composed of an indefinite number of joints, inserted above the eyes ; they vary much in length and structure. Often they are pectinated; i.e. the upper angle of each joint is developed into a slender chitinous process like the tooth of a comb ; if there are two rows of such pro- cesses, the antenna is bipectinated, if one, unipectinated. If not pectinated, they may be dentate, serrate, or filiform. Very frequently they are ciliated; i.e. furnished with one or two series of usually short fine hairs, closely and evenly arranged ; when the hairs are collected into fascicles or bundles, which usually happens when they are longer, the antennae are said to be fasciculate-ciliated. Occasionally they are pubescent ; i.e. clothed all over their surface with a short fine down. Some- times they are furnished with special structures, such as thicken- ings, notches, sinuations, or tufts of scales. The nature of the sense located in the antennae is not known ; but very generally the antennae of the male show an increase of development as compared with those of the female, and there can be little doubt that one of their functions is to enable the former to find the latter. INTRODUCTION The proboscis, or tongue, is an extensible tubular organ, fitted for sucking up the nectar of flowers, and usually spirally coiled when not in use ; it is composed of the maxillae, which are semitubular and closely appressed together at the edges, but separable at the will of the insect ; this arrangement enables the apparatus to be cleansed internally. Although it is usually the only means of taking food, it is in some species absent or so rudimentary as to be useless. The mandibles are biting jaws, working against one another sideways; they have only been observed in a functionally active condition in Eriocephala, being apparently aborted or rudimentary in all other imagos, though necessarily well developed in the larvae. The maxillary palpi are jointed organs rising from the base of the maxillae ; when fully developed they are six-jointed and usually more or less folded on themselves, but in the large majority of species they are reduced to mere rudiments, their functions being probably assumed by the labial palpi. In certain groups they occur in an intermediate three-jointed stage, somewhat resembling the labial palpi, but on a much smaller scale. The labial palpi are normally three -jointed organs, rising from the labium or lower lip, and projecting outside the maxillary palpi. The basal joint is generally small and incon- spicuous, but the other two in some groups vary greatly in size, form, and scaling. They may be straight or curved ; drooping, porrected, or ascending ; smooth, rough, or tufted ; obtuse or pointed. The palpi are usually regarded as organs of touch, but no explanation of their variety of form has been suggested ; they are independently movable, but in the case of the Lepidoptera it does not seem that their use is really understood. The thorax varies little except in scaling, and the presence or absence of dorsal crests. Covering the shoulders are two chitinous scaled flaps, termed the patagia. The abdomen is sometimes also furnished with dorsal crests. At its base are two lateral cavities, more or less developed, which appear to be the organs of some sense. The abdomen terminates in a tuft of scales covering the orifice, the anal tuft. Within the orifice are concealed the genital organs, which are capable of protrusion ; and also the ovipositor of the female, though this is in many cases permanently exposed. The genital organs of the male differ greatly in INTRODUCTION different species, and can often be used as a reliable point of distinction between closely -allied species; but they do not seem in general to afford trustworthy characters for wider classification, and are as yet insufficiently studied. Those most readily discernible are two lateral clasping organs, termed the prensors, and a curved upper process, termed the uncus ; these are variously shaped, and often furnished with spines or hooks ; they are often accompanied by an expansible tuft of fine hairs, known as the genital tuft, which is a scent-producing organ. The legs are made up of coxa, femur, tibia, and tarsus. The coxa, or basal joint, is short and varies little. The femur (plural femora) is sometimes hairy, or furnished with tufts. The anterior tibia is usually comparatively short, and furnished beneath with a median spine-like process, sometimes also with an apical hook ; the middle tibia is normally provided with a terminal pair of spurs, and the posterior tibia with median and terminal pairs of spurs; frequently the posterior tibia (more rarely the middle one) is furnished in the male with an expan- sible pencil of hairs contained in a longitudinal groove, serving as a scent-producing organ ; all the tibiae may be spinose or hairy. The tarsus is composed of five joints (the basal being- longest), and terminates in two claws ; it is often more or less spinose ; occasionally it may be partly or wholly aborted, when the leg is modified for other purposes than walking. The wings were perhaps originally tracheal gills, respiratory organs afterwards modified for purposes of locomotion. In form they vary from triangular to almost linear, but the triangular shape may be taken as typical. The junction of the wing with the thorax is the base ; of the two other angles the upper is the apex, the lower the tornus ; of the three sides the upper is the costa, the lower the dorsum, and the outer the termen. The termen and dorsum are edged with a fringe of short hairs, the cilia; when, however, the wings are very narrow, as in many of the Tineina, these cilia are greatly developed in compensation, being sometimes six times as broad as the wing itself. Generally from or near the base of the costa of the hindwing rises a stiff bristle or group of bristly hairs, termed the frenulum, of which the apex passes under a chitinous catch on the lower surface of the fore wing, termed the retinaculum, thus serving to lock the wings together ; the frenulum is commonly single and strong in the male, multiple and weak in the female ; the retinaculum in the female is com- INTRODUCTION monly represented by a group of stiff scales. When there is no frenulum, the costal area of the hindwing is generally dilated nasally, so as to rest more firmly against the forewing, and avoid dislocation. But in the Micropterygina (as recently discovered by Professor Comstock) a different system prevails ; a membranous or spine -like process called the jugum rises from the dorsum of the forewing near the base, and passes underneath the hindwing, which is thus held between the process and the overlapping portion of the forewing. The wings are traversed by a system of veins, tubular structures which serve at once as extensions of the tracheal system, and to form a stiff framework for the support of the wing. In the normal type of Lepirfoptera the forewings possess three free veins towards the dor- sum, termed la, Ib, and Ic ; a central cell out of which rise ten veins, numbered 2 to 11, the sides of the cell being known as the upper median, lower median, and transverse veins respectively ; and a free subcostal vein, numbered 12: whilst the hindwings differ from the forewings in having only six veins rising from the central cell, numbered 2 to 7, so that the free subcostal vein is numbered 8. In some forms a forked parting- vein traverses the middle of the cell longitudinally, and a second parting- vein traverses the upper portion, so as to form a secondary cell ; but these are more frequently absent or represented only by folds in the membrane. In a few forms there is a tendency to the production of several false veins, termed pseudoneuria, appearing as short branches from the subcostal vein of the hindwings to the costa ; these are thickenings of the membrane, and are commonly very irregular and variable, often uneven in thickness or incomplete. Some- times one of these near the base is better developed and more permanent in character ; it is then termed the praecostal spur. Modifications in the general arrangement of the veins may arise through any of the following processes, viz. : (1) obsolescence, when a vein loses its normal tubular structure, becoming attenuated and reduced in substance, until it appears a Assumed type of neuration of the Lepidoptera. INTRODUCTION mere fold of the membrane ; (2) stalking, when two veins are fused together for a portion of their length from their base, so as to appear to rise on a common stalk ; (3) coincidence, when two veins are fused together for the whole of their length, so that one appears entirely absent, an extreme form of stalking ; (4) anastomosis, when two veins rise separate, meet and are fused together for a certain distance, and then separate again ; (5) concurrence, when a vein rises separate, runs into another, and does not separate again, an extreme form of anastomosis ; (6) connection, when two veins are connected by a short trans- verse bar passing from one to the other, a special form of anastomosis, evolved from the ordinary form under the influ- ence of a tendency to lateral extension. Vein Ib in both wings is often furcate at the base. The type of veins in the Micropterygina differs from that described above in two essential particulars, viz. (1) there may be three additional veins in the forewings, rising out of vein 11 or 12 ; and (2) the veins of the hind wings are practically identical in number and structure with those of the forewings, being thus much more numerous than in the ordinary type. There is also often a system of cross-bars between the veins near the base of the wing. The structure of the veins can be best observed on the under -surf ace of the wing, where they are more prominent. The student should begin by completely denuding of scales a few wings of common species ; the wing should be cut off and laid on a moistened piece of glass, to which it will adhere ; the scales should then be removed, first from one surface and then from the other, with a fine moist camePs-hair brush, an operation requiring a little patience and delicacy of touch ; the veins will thus be rendered conspicuous. When, however, the student has familiarised himself with the general subject, it will not be found necessary in practice to resort to this process ; most details will be easily observed without denudation ; where this is not the case (as where the veins are closely crowded or otherwise obscured), the scales can be removed with the brush on the under-surface in the locality of the difficulty only, without cutting off the wing or otherwise damaging the speci- men, which remains in the collection available for all purposes as before ; with proper practice, even the smallest species are amenable to this treatment, which does not require more skill than the actual setting of the specimen. Some workers prefer to put a drop of benzine on the spot, which renders it tern- INTRODUCTION porarily transparent ; the effect is short-lived, as the benzine evaporates rapidly, and the cilia (if long) are liable to be damaged by this method. Pupa. The pupa is wholly encased in a chitinous integument, rendering the ordinary organs of locomotion useless ; but some pupae, which are subterranean or inhabit the hollow stems of plants, are capable of working themselves along by means of rings of spines on the margins of the abdominal segments. In the more ancestral forms of the Lepidoptera the chitinous envelopes of the antennae, legs, and other organs are more or less free and detached from the general integument, though incapable of movement; whilst in the more advanced forms the cases of these organs are fused with the general integu- ment. The only recorded instance of active organs in a Lepidopterous pupa is that of Micropteryx, in which the large mandibles and labial palpi are functionally active. The seg- ments of the abdomen may be either free (movable at their base) or fixed, the number of free segments differing in different groups and genera ; in the earliest forms the segments are all free, but the number of free segments tends continually to diminish ; in certain Papilionina and Tineina all are fixed. Usually the pupa is enclosed in some sort of cocoon, but this protection is sometimes dispensed with. In most cases it is concealed beneath the surface of the ground or amongst leaves and refuse ; in the case of mining species it is often within the mine ; less frequently it is entirely exposed, attached by the tail and sometimes by a median silken girdle, and is then usually protectively coloured. When dehiscence (the breaking-up of the pupal integument to allow of the escape of the imago) takes place, in the earlier forms the cases of the various organs remain intact, the organs being simply withdrawn from them; whilst in the more advanced forms the inner wall of these cases, being extremely slight, is practically destroyed, and the general integument is broken up irregularly. Larva. In the larva the thirteen segments are usually clearly de- fined ; they are referred to hereinafter by their numbers, 1-13, 1 being the head. This is furnished with simple eyes and strongly- developed mandibles ; antennae are usually rudimentary, but INTRODUCTION in Eriocephala developed. Usually there is a spinneret beneath the mouth, from which a fine silk is produced. Segments 2-4 bear each a pair of true jointed legs, corresponding to those of the imago, seldom absent. In addition to these there are also in the normal type of Lepidopterous larva ten prolegs, sucker- like extensions, whose extremities are furnished with series of minute hooks, situated in pairs on segments 7-10 and 13, but some or all of these may be rudimentary or absent. In the archaic Eriocephala there are prolegs on 5-12 ; and in one or two other instances there are rudimentary paired ventral pro- cesses on other segments than those on which prolegs normally appear, but so little developed that it can hardly be deter- mined whether they are really homologous with the true pro- legs or not. The surface of the body is furnished with numerous dots, spots, or tubercles (variously styled according to their character, which varies much in different species), of which some at least usually bear each a fine hair, or sometimes dense fascicles of hairs ; sometimes these tubercles are developed into spinous processes, branched with hairs. The spiracles, or orifices of the respiratory tubes, are placed in a row along the sides of the body, not far above the legs. The contractile dorsal vessel, which is the main circulatory organ, runs along the middle of the back, and is often visible through the skin. The whole growth of the insect takes place in the larval stage, the increase of bulk being frequently very rapid. During the process the larva casts its skin several times (usually from four to six), sometimes undergoing considerable changes of appearance and habit on these occasions. The markings of larvae usually take the form of longitudinal lines ; of these the one which runs up the middle of the back is termed the dorsal, that which includes the spiracles the spiracular line ; those which margin the spiracular are the supraspiracular and subspiracular respectively ; between the dorsal and spiracular are placed two others, the upper being the subdorsal, the lower the lateral. These are seldom all present; the dorsal and spiracular alone rest on a structural basis, the others being assumed by a useful convention. Ovum. The ovum, or egg, is small and more or less globular ; its surface is frequently sculptured, and assumes special char- acters in particular groups ; the colour usually undergoes marked changes during the development of the embryo. INTRODUCTION Variation. Probably variability is an original characteristic of all organisms ; but the laws of inheritance, and the favouring of a particular type by natural selection, have tended to pro- duce constancy. This constancy is, however, often imperfectly realised ; that is to say, all insects show more or less variation in some particulars. Thus there is always some variability in size and proportions ; often also in colour and markings. Varia- tions in structure are less common ; in certain groups there is variability in some details of neuration. Allied species may be expected to vary in the same way, but otherwise experience is the only guide, the same characters which are absolutely constant in one group being often highly variable in another. Varieties may be broadly classified as being of two kinds, viz. gradual and sudden ; the former being connected with the type-form by numerous slight intermediate gradations, the latter not so connected. The former kind represent the outcome of those subjective tendencies to variation which have not been eliminated by the working of natural selection, and may be termed normal ; whilst the latter are apparently due to some objective interference with the process of develop- ment, and are in that sense abnormal. The line between these two classes is not always easy to draw in practice, but the distinction is real. Gradual varieties attached to a particular locality or region are called local or geographical forms; those occurring at a particular time of year seasonal forms. Variation caused by the failure of colouring matter is termed albinism ; that due to an excessive prevalence of black pigment is melanism ; but the application of these terms to varieties which are merely lighter or darker than usual is erroneous. Specimens showing sudden variations in colour or marking are commonly termed aber- rations; in structure, monstrosities. The most common examples of monstrosities are produced by multiplication of parts, as when an insect possesses an additional leg or vein ; or by gynandro- morphism, the term used when an individual of one sex exhibits on one lateral half the organic characters of the other sex, more or less completely. Principles of Classification. It is now admitted that the resemblances of allied genera and species are to be explained by community of descent. 10 INTRODUCTION Hence a system of classification will be natural or artificial, according as it does or does not keep steadily in view this principle, with which all sound results must be consistent. When it has been decided that a number of genera possess so much mutual resemblance in structure that they may be regarded with probability as constituting a distinct branch of the genealogical tree of the Lepidoptera (and this is what is meant by family grouping), the question must arise, which of these genera are older than the others, and which are the latest developments. It may often be difficult and sometimes impossible to answer this, but in most cases an approximate result can be reached by a consideration of the following laws, viz. : — (1) No new organ can be produced except as a modification of some previously existing structure. (2) A lost organ cannot be regained. (3) A rudimentary organ is rarely redeveloped. To the first of these laws certain monstrosities offer an apparent (though not real) exception, but as there is no evidence to show that such monstrosities are ever reproduced under natural circumstances, they may be omitted from calculation. Certain other considerations may likewise be of assistance. A large genus, especially if also of very wide distribution, cannot be a very recent one, since it must have required a long period for the differentiation of numerous species, though it must be remembered that as the genus grows larger, the process may become more rapid, from the increased basis of production. On the other hand, a small genus may be of any age ; but one which is closely related to a large genus will almost always be later than it, and a small genus which is widely distributed must generally be an old one. In applying the above-mentioned laws in practice, it must be constantly borne in mind that, because two genera are now more closely allied together than to any other, it does not follow that either is descended from the other; it is very frequently the case that both are equally derived from a third genus now no longer existent ; in such a case they are said to be correlated. Further, when one genus is said to be derived from another, and the earlier genus is rich in species, it is not usually meant that the later genus springs from the more advanced forms of the earlier one, but much more commonly from a species standing very near the bottom of the list. INTRODUCTION 11 In determining the relative value to be assigned to different characters for the purposes of classification, those characters which are adaptive, i.e. liable to be affected by external agencies through the means of natural selection, are generally very un- trustworthy. Conversely, a character which seems of little physiological importance, and not easily modified by ordinary external influences, is commonly of especial value. Thus colour and outline, the hairs of larvae, and the genital organs of imagos are likely to be of slight importance in the definition of groups ; whilst neuration occupies a high position, except when directly influenced by an alteration in form of wing, which is seldom the case. A combination of several characters which are apparently not interdependent carries very great weight. It is sometimes said that genera (and families) are artificial creations. If by this is intended that they consist of a certain number of species having no other relation than the common possession of certain characters, the statement is not true of any sound system, and the systematist who makes it stands self-condemned ; but if it is only taken to mean that the precise limits of genera may often be differently conceived by different workers, it is to that extent quite true. If two small allied groups of species agree in all essential characters, and are capable of definition as a whole which can be distinguished from all other groups, yet are also constantly separable from one another by a single and perhaps slight character, the question whether they are to be reckoned as two genera or as sub-groups of a single genus must always remain one which may be answered differently by different workers. The same is true of families; and a consideration of the nature of a genealogical tree and the diversity in the length of its branches will show that it is unreasonable to expect all individual groups of any particular denomination to be of the same actual value. Some writers have urged that secondary sexual characters should never be used to define genera. No doubt there is a convenience in only using such characters as are common to both sexes, since the student who is trying to identify the insect may only possess examples of one sex; but there is absolutely no scientific justification for the restriction, which would make the classification of some groups of Lejndoptera quite impracticable ; when such structural characters are found in any instance to assist the definition of natural genera, there is no reason in nature why they should not be employed with perfect freedom. 12 INTRODUCTION Phytogeny. This term is used to express the scheme of descent of a group. From a consideration of the laws enunciated above, there can be no doubt that the Micropterygina are the ancestral group of the Lepidoptera, from which all others have descended ; this is sufficiently proved by the existence of the four or more additional veins in the hindwings of that group, for these veins, if not originally present, could not have been afterwards pro- duced. Of the two families of that group, the Micropterygidae, which possess an additional vein (or veins) in the forewings, and fully-developed six-jointed maxillary palpi, must be more primitive than the Hepialidae. Now if the neuration of the whole of the Lepidoptera is compared with that of all other insects, it will be found that in no instance is there any close resemblance, except in the case of the Micropterygidae ; but the neuration of these so closely approaches that of certain Trichoptera (caddis-flies) as to be practically identical. The conclusion is clear, that the Lepidoptera are descended from the Trichoptera, and that the Micropterygidae are the true connecting link. If the other marked structural characters of the Micropterygidae are taken into consideration, viz., the possession of the jugum, the large development of the maxillary palpi as compared with the labial, and the sometimes functionally active mandibles, they will be all found commonly in the Trichop- tera, affording additional confirmation. It may be added that in one exotic (New Zealand) species of Micropterygidae, vein Ib is basally trifurcate, a character frequent in the Trichoptera, but not yet discovered in any other Lepidopteron. In most Trichoptera the veins of the hindwings are much more numerous than those of the forewings, in the Micropterygina they are usually equal in number, in other Lepidoptera they are less numerous ; in the course of descent there has therefore been a greater progressive diminution in the number of veins of the hindwings as compared with those of the forewings, though these have also diminished. It is unnecessary for the purposes of this book to trace back the descent of the Lepidoptera further ; lout it may be worth while to point out that we may assume as the primitive type of Trichopterous neuration, a system of numerous longitudinal veins gradually diverging from the base, mostly furcate ter- minally, and connected by a series of irregularly placed cross- bars near base, and another series beyond middle.

A dominant family in temperate regions, especially in the northern hemisphere, the species being very numerous and often occurring in great plenty ; within the tropics, however, their place is largely taken by the Plusiadae. The structure is in most particulars remarkably uniform, the neu- ration and palpi being practically identical throughout thefamily. The markings are usually very similar, and the colouring dull and adapted to conceal insects which are accustomed to hide amongst dead leaves or refuse ; hence this group is not one of Neuration of Melanchra brassicae. 44 CARADRINHSTA the easiest or most attractive to study. The species are the most truly nocturnal of all the Lepidoptera; few are readily obtainable by day, but at night they are found in abundance at flowers or sugar. Imago with forewings usually elongate, body relatively stout, and densely scaled. It may be noted as an established conclusion that antennal pectinations, if not extending to the apex of the antennae, are in this family seldom sufficient to mark generic distinction. Ovum spherical, more or less distinctly ribbed and reticulated. Larva usually with few hairs (except in the earliest forms), often nocturnal, sometimes subterranean; often very poly- phagous. Pupa usually subterranean. The phylogeny of the leading genera is expressed in the accompanying diagram. PHYLOGENY OF CARADRINIDAE. Cucullia I.

Hindwings : 5 fully developed, 6 from angle, 7 from upper margin at f, 8 closely approximated to 7 beyond cell. Only a small group, nor is there any evidence that it has ever been much more extensive ; it is mainly restricted to the northern hemisphere. The images have mostly stout bodies and elongate -triangular fore wings, and have some superficial resemblance in form with the Carad,rinidae, with which how- ever there is absolutely no relationship. The similarity of the neuration of the hindwings to that of some Lasiocampina is probably reversional. Ovum spheroidal above, flattened beneath, surface finely reticulated and sometimes ribbed. Larva moderately stout, with all prolegs developed. Pupa in a rather slight cocoon usually amongst leaves. Occasionally in the forewings, by obsolescence of a small connecting portion of the vein, 9 appears to rise out of 10 and have no connection with 8 ; or possibly this may be its true original structure. The phylogeny of the genera, which are all nearly related together, is probably fairly indicated by the arrangement. TABULATION OF GENERA. 1. Eyes hairy . . . .4. POLYPLOCA. „ glabrous . . . . .2. 2.
