Copyright 1938 by Alfred Kernen, Publisher, Stuttgart. * Printed by n. Laupp ji, Tubingen. V Foreword, (Partly from Notes left by Prof. Dr. Ad. Seitz, who died on 5th March 1938.) The publication of Main Volume III of our monumental work took place in the years 1909 to 1913 and the Editor in his remarks in the Preface of this Supplementary Volume mentioned, that in broad out¬ line, the arrangement of the original Volume would be followed and in general this accords with the principles of Hampson’s Catalogue of the Lepidoptera Pludaenae and other existing Catalogues. As, however, Hampson's masterly work appeared after ours, Warren, who edited our Main Volume III, did not have the advantage thereof and was unable to arrange his classifications and systematization etc accordingly. This would, of course, have been desirable, had it been possible. The Editor of this Supplementary Volume considered it of prime importance, for reasons of comparison and lucidity, to follow our original classification and not to re-arrange matters on the basis of Hampson's work. There are therefore certain discrepancies, as for instance, in the Acronictinae, Mominae and Bryophilinae, where our publication was “issued before Hampson's corresponding chapters were ready. Hampson classified the Acronictinae subfamilies after Amphipyra etc. On the other hand the Melicleptriinae and Heliotkidinae, which we have placed near the end of our Volume, would, on account of the spined tibiae, have had to be placed at the commencement near the Agrotinae. Neither the Editor nor the Publishers have overlooked the fact that during the last few years a per¬ ceptible evolution has taken place in descriptive Entomology. Greater importance is continually being attached to anatomical and microscopical details, as compared with the earlier method of macroscopical characteristics and the habits of the insects. A number of renowned scientists has come to the conclusion that the modern, more physiological examination of specimens calls for a more exact differentiation, based on structural charact¬ eristics. These are said to be of greater importance than the earlier more obvious and superficial features and it is held that they should be given first consideration. It can easily be realised that, from our standpoint, we are reluctant to introduce a rather one-sided system of basing ourselves almost exclusively on anatomical differences. We have to bear in mind that ours is a general work, that 95% of our readers are amateurs, en¬ thusiasts and collectors, whereas only 5% are scientists. Prof. Dr. Seitz has also repeatedly drawn attention to the fact, that in a work that is limited as to capacity, it is impossible to give too minute anatomical or extensive descriptions. In the Supplement of the Macrolepidoptera of the World, a little more latitude has been allowed in this regard and where space has permitted, the Editor has given rather more detail than in the past. Further we have felt that our illustrations are the best and most desired medium, not only for the purpose of denominating, but also for the arrangement of collections. Over 4000 illustrations were given in the Main Volume and we have now added a further 1600. The technique of the illustrator's art has made notable progress in the last 20 years. Very numerous new species have been discovered, especially in palae- arctic Asia and Africa. Many forms also, that were previously not available, have now been secured for illu¬ strative purposes. In the Preface of Volume HI it was mentioned, that some of the illustrations, especially of the rarer species, left much to be desired, as only poor illustrations in former works were available for repro¬ duction. In many cases these have now been replaced by better illustrations, as the difficulties of obtaining fresh types of the original insects have been overcome. As the Editor has explained in the subsequent short Preface, as a matter of principle, British specimens have been used as typical of British species. Little atten¬ tion was paid in the past to small divergences from continental specimens of the same moth. The task of the Macrolepidoptera was never intended to be a monographic differentiation of local races, but a brief account of the characteristic features of each species and its main subforms. The great majority of aberrations that are VI FOREWORD. denominated today, have for the last 100 years and even longer, been known and simply classified with the type species and this has been the case even in the best arranged private collections. No one ever thought of taking exception to such a system. It is mainly due to Tutt, that the new system of denominating all shades of variety, has been introduced. While this was well known when Volume III was being published, it had not yet become a general practice. Therefore many specimens were illustrated as the type, which today, in consequence of the publication of some highly specialised monograqth, would have a separate distinct designation. In this regard some criticisms have not been merited and further, some denominations have been made, that are quite unjustifiable. For instance the naming of faded specimens. Even with the utmost care and when a collection is kept in cabinets, that are seldom exposed to the light, it is a well known fact, that just with the N octuidae, the colour is liable to change, more or less, in the course of years. The grey-blue and slate coloura¬ tions are liable to alter to a yellowish brown hue, an occurrence, of which one has long been awrare, but which, when taking a broad view, should be considered quite natural and of no particular moment. Further, owing to the many expeditions of later years, certain species have been found in large numbers, whereas formerly but a single faded, worn or damaged specimen was known. In such cases these naturally had to serve the artist as the model for the first illustration of a type. The artist is often in an unenviable position, when, for instance, the owner of an unique specimen, would not part with it even temporarily, but in order to show his good will, tried in an amateur way to make a drawing or a water colour sketch. This was often very unlike the real thing and not in the least true to nature. May we ask our readers to bear in mind, that the exact reproduction of the N octuidae. is one of the most difficult tasks that exists and to crave their indulgence therefore, if every¬ thing in this Supplementary Volume is not up to perfection. It will be readily understandable, that had we give full consideration to all the recently published anatomical details, these would have proved an insurmountable obstacle to a rapid completion of the present Supplementary Volume. In any case, constant revision became necessary in an attempt to bring matters up to date and to keep in step with the many new publications dealing with examinations of the genitalia. The Volume was practically ready for final publication in 1935, when a second and yet a third Addenda had to be made in an attempt to include, as far as was possible, all the new material that had become available. The size, that this Volume would have assumed, can easily be imagined, had all the Genera been revised on the basis of recent anatomical examinations, in the same way as Dr. Corti has dealt with the Agrotis and Boursin the Athetisl Further revisions of this nature are indeed planned and already in preparation and the Editor has had to consider whether it would not have been better to wait with the completion of this Volume until these publications were available. The details they may reveal and which may help to complete our know¬ ledge, could then have been included here. At present also the most interesting parts of the palaearctic terri¬ tory, the regions where many a secret may yet be divulged — the entire centre of Asia and the greatest part of the Chinese territory — are just at the moment yielding such a wealth of new forms, as has never been known before. The systematic exploration and examination of the fauna of the numerous and diverse chains of mountains in the South and on the borders of Mongolia and the methodic collecting, that is now going on there, especially through the intrepid persistence and activity of Dr. Hoene, are giving the most astoni¬ shing results. It might therefore seem to many, quite incomprehensible, that this work should be completed just at a time, when in a relatively short period, its incompleteness and imperfections may become apparent. Nevertheless there must come a time for finality and the period, that had been set for the completion of the whole series of palaearctic Volumes, has already been far exceeded. Continual pressure has been brought to bear on the publishers to press forward with the final publication of this Volume. It may be remarked that the Editor himself is most reluctant and has only decided with a very heavy heart to desist from waiting a little longer in the hope of including some of the numerous, partly quite exceptionally interesting new disco¬ veries, which are now available, but which have not yet been comprehensively examined scientifically. All we can hope is, that this Supplementary Volume III will be found to be not merely an addition to the Main Volume, but in many ways, an improvement thereon. Some of the more recent publications and here Ave again especially mention Sir George Hampson's Catalogue, will then have in no mean measure con¬ tributed to this success and the help derived from them is here gratefully acknowledged.

In considering the palaearctic Noctuidae we are dealing with the same geographical territory as set out in Vol. 1 of the Supplement. Consequently the large increase in the number of palaearctic Noctuidae and especially the last groups of the same, the Hypeninae, is excluded as these have chiefly been found in Formosa from whence most of the new descriptions emanate. Formosa decidedly does not belong to the palaearctic group. Thanks to the excellent methods of capture and research Noctuidae show a rich addition of many genuine species, subspecies and local forms. Nearly throughout, a reasonable limit has been set in denominations of new aberrations and an excessive subdivision has only taken place in very few species. The generally more uniform colouration and the very similar type of markings do not encourage nomenclature. Consequently the new names are chiefly for genuine species and or subspecies and this is an agreeable result of the Work of the last years. The additional knowledge has been particularly rich in regard to north african discoveries which are consequent upon the intensive research of Oberthur, Rothschild and Titrati. We have here quite an astonishing wealth of forms. A considerable quantity of new information has been added from the Far East and Japan, and latterly especially also from Spain through the active collecting mainly by austrian collectors. The handling of the subject matter in Vol. Ill of the original work did in many respects not give complete satisfaction. The text was too brief and insufficient in regard to many of the descriptions. Frequently also the german translation of the original english text was unsatisfactory, or the translation did not express that which was intended. Further the colour designations in the two languages do not express identically the same because the english expression indicates a different shade than in the german translation. We mention for instance the word “purple”. As has been proved in the meanwhile many species and forms were not properly dealt with and others were quite omitted. Every effort will be made to remedy these deficiencies and omissions in the Supplement. What has just been said in regard to the text also applies but in a greater degree to the handling of the plates. One must admit that just in representing Noctuidae one meets with a large measure of difficulty both from the standpoint of the drawing as well the colouring. It is only in the rarest cases that it is possible to give a perfect representation such as would be possible by an expert draughtsman, like Citlot. In the main volume in general all the Noctuidae which occur also in England were illustrated from english specimens. In many cases this explains a certain divergence in the appearance in comparison to the usual continental forms. Thanks to the collaboration of many public institutes it has now often been possible to replace poor illustrations by new ones taken from original specimens. In this regard the unique and comprehensive collection of Pungeler in the Berlin Museum has rendered most valuable services. Pungeler had promised shortly before his death to give me every help in dealing with the Noctuidae. Unfortunately his premature death cancelled these hopes, but fortunately the documents and records which formed the basis of his collection and are a testimony to his unusual care and discernment are at my disposal. We also owe a debt of gratitude to the Museums in Munich, Dresden, Stuttgart and Tring, and further to many other well known collectors, especially Mr. Otto Bang- Supplementary Volume 3 1 o PREFACE. By Dr. M. Draudt. Haas, Fritz Wagner of Vienna and Mr. Dannehl who have so kindly placed very valuable type material at our disposal. In broad outline we have followed exactly the classification of the material according to the subdivision in Vol. Ill of the main Work. In general this followed the principles of Hampson, whose volumes of the Cat. Lep. Phal. however were not available at the time the Work Was published so that also in this respect complete perfection was not achieved. There will be little to criticise apart from the interposition of the Mominae, Acronyctinae and Bryophilinae which in any case are a strange conglomeration. However in the interest of an easy comparison we have followed the systematic arrangement of the main part of the Work, more especially as in most other Works on the subject this old order is still followed.

This north indian species described in Vol. XI, p. 5 and also illustrated on Plate 4 a maculatrix. has predominantly white spotted forewings in the type form. It occurs in W. China on the frontier of the pal- aearctic region in a partially yellow spotted form for which Strand has given the following denominations : - ab. antemedialis Strd. (= ab. i Hvips.) with upper half of the antemedian and median cell spots of forewings antemedia- coloured yellow. — ab. cellularis Strd. (= ab. 3 Hmps.) is similar but has the spots behind the upper angle of the c.c??i(?arJ*s' cell also yellow. — ab. angulan's Strcl. (= ab. 4 Hmps.). In this case also the spots behind the lower cell angle angularis. are yellow. All these forms occur on the Omei-shan and at Moupin. This species should be classified before E. lecfrix. lectrix.

P. coenobita Esp. This species advances to the north as far as the Baltic Provinces, in E. Prussia it is coenobiia. occasionally very frequent without however becoming a pest; it is common on Saghalin in the middle of July; towards the south it is found as far as N. Italy. — In ab. latefaseiata Bbl. the black markings in the discal area latejasciuia. become heavier forming a black discal band, whilst the basal and marginal areas continue to remain predom¬ inantly white. — ab. immaculata SJielj. is based on a $ found in Germany: it is without orbicular or reniform immuculata. stigmata which are apparently covered over by the transverse lines which are displaced. — In the Amur region this species occurs as a special subspecies: ussuriensis Warn. (= kotschubeyi Shelj.), it is much larger than the ussuriensis. european form, the black spots are somewhat diffuse and appear to stand on lighter ground. The white ground colour thereby becomes more prominent. This is a distinct form from Ussuri. 2. Genus: Moma Hbn. M. ludlfica L. The name type generally varies little and the species is therefore scarcely to be mistaken ludifica. for any other. — ab. dlffusipicta Strd. is distinguished by the more diffuse markings of the fore wings, hind wings diffusipicta. are quite suffused with black with the exception of the inner marginal area which retains the yellow. Probably the name is synonymous with — ab. lugens Gulot (1 a), established from a specimen caught at Dresden. This lugens. probably represents the melanic extreme of this form of aberration. The type is found besides in mid-Europe, southwards to E. France, also in the Bretagne; northwards it is found as far as Reval. M. champa Moore — v. ainu Wilem. differs by the more distinct posterior transverse line of forewings ainu. which forms an arc from the costa to beyond the middle of the wing and then proceeds obliquely to the inner margin; hindwings yellowish widely margined with blackish. Japan, Yesso, Kiushiu. 6. Genus : JMphtliera Tr. D. alpium Osb. In the form designata Trti. (la) from a specimen from Sestola, in the Apennines of designata. Modena, the black markings are absent in the discal area that usually traverse between the stigmata from costa to inner margin. — glauca Trti. from Camaldoli is clearly a further stage in evolution, here the basal and sub- glauca. marginal black markings are also absent; fringes are quite white, the green is restricted to 2 bands of spots, one median and the other antemarginal. In contrast to the designata form we have — fasciata Lenz (1 a) with fasciata. a coherent wide black middle band. It is described from Bavaria. The name type is found eastwards as far as Saghalin. In northern regions the larvae are found chiefly on birch, as for instance in Esthland. 7. Genus: Oolocasia Hbn. G. coryli L. A number of varieties have been described. — ab. avellanae Huene (1 a) is a uniform grey avellanae. form without any brown marking in basal area, this has often been observed and occurs from Esthland to S. Bavaria and the Tyrol. — nielanofica HaverJcpf. ( = weymeri Hold) (1 a) is a specimen that is uniform sooty melanotica. black over the body and wings, only the basal half of the wings being faintly darker. It is found in the industrial regions of the Rhine (Elberfeld and Barmen). — ab. mediortigra Vorbr.: concurrently with the typical form, medionigra. 6 OXYCESTA; EOGENA; SIMYRA. By Dr. M.

On the other hand however it has a black-brown marginal spot on fore wings; hindwings also are paler, fringes grey intersected with white. — ab. wautersi Dufrane is smaller by y3 rd: the pale grey area between the postmedian and the fringes is red-brown, the discal area is sharply outlined with pale brown. Described from 3 specimens from the neighbourhood of Antwerp. - betulae Lenz is an aberration of the larva not of the imago. They were found in upper Pomerania on birch and it is to be presumed that this form will be occasionally found elsewhere ; the larva is of violet-black colour having warts with white hairs and a white lateral row of spots; the lateral hair tufts on the 1st and on the 11th segments are black, the bristles on the 4th and 5th segments are rusty red. — The following local forms are established: — uniformis Trti. from Calabria with uniform brown ground colour in contrast to the uniform grey of avellanae or mus; only the outer edge of the reniform mark remains light. — umbrosissima Trti. is a much larger form from Sardinia; the dark outline of the brown basal area is more pronounced, forming a deep dark brown triangular discal band. It occurs in April in fairly high altitudes (Mte. Gennargentu) up to June. — subsp. ussuriensis Karel, differs distinctly from european forms by the anterior transverse line which is situated further from base, it has a narrower grey-black discal band which has no brownish yellow colour and there is a shadowy transverse band reaching to the reniform stigma; marginal area is paler than typical specimens, orbicular stigma with black spot, reniform stigma pale, hindwings and fringes unicoloured grey-brown. From Narva and Vladivostok in June. — ab. grisescens Karel. : occasionally among the same quite pale grey specimens occur with very fine transverse lines and reniform stigma without central dot and quite pale hindwings, which differ from the similar mus by the light basal area and the paler reniform stigma. C. suzukii Mats. (= sugitanii Mats, in tab.) (1 a) is very close to coryli. Frons, neck and palpi are black- brown, fore wings dark grey with dark black-brown transverse lines, the anterior one almost straight only somewhat bent below the costa, discal line undulate bending out considerably from inner border of reniform stigma. The narrow posterior line is almost parallel to the discal line, all 3 expand at the costa; subterminal area dusky, the undulate marginal outer border black-brown, edged with whitish posteriorly, similarly a fine marginal line; the black-brown fringes are intersected by white at the extremities of the veins; the costal margin is white to beyond the small indistinct orbicular and the whitish reniform stigmata. Hindwings dark grey. Expanse 28 mm. Described from a $ from Honsho (Kyoto). C. umbrosa Wilem. Forewings grey, the basal %rds dusted with brown, outer edge oblique; marginal area dusted with black-brown; the anterior irregular transverse line blackish, the posterior one undulate being bent round the end of cell; an undulate subterminal is indistinct, both stigmata circumscribed by black; hind¬ wings blackish brown. Wing expanse 34 mm. Smaller than mus which it resembles, the posterior transverse line being of different formation. Japan. 8. Genus: Oxycesta Hbn. 0. serratae Zerny (= geographica var. Zap. y Korb, chamaesyces Ghapm.) (1 a). Ground colour darker olive-brown than geographica and has more pointed transverse lines with deeper dentations and much darker grey hindwings especially in the whilst in the they have whitish patches at the inner margin and in the dentate postmedian. Considerably larger than chamaesyces, with wider wing contour and more varied pronounced markings and more distinctly checked fringes. The genitals of the 2 species are also different. It occurs in May and beginning of June in Aragon. The larvae feed together in June and July in open sunny spots on Euphorbia serrata. 9. Genus: JEogcna Gn. E. contaminei Ev. — ab. contaniinella Strd. from S. Russia has pale reddish hindwings, they are somewhat darker in marginal area but without brown colouration. 11. Genus: Simyra 0. S. moltrechti 0. B.-H. (1 b) apparently closely resembles bilttneri, the wing contour is somewhat shorter and wider, ground colour of forewings pale yellow, more whitish at base, sparsely and finely sprinkled with black. An outer transverse line is indicated by minute dots on the veins forming a wide arc around the end of cell. Hindwings grey traversed from base to margin by brownish longitudinal streaks. Wing expanse <$ 26, $ 24 mm. From Sutschansk (S. Ussuri), captured in August. S. autumna Ghret. is classified behind dentinosa, which it resembles. Apex of forewings somewhat more rounded than in other species. Red-grey, veins black or blackish with traces of 2 transverse lines, these extend very obliquely to dorsal half of the wing and end at the inner margin in y3 rd and %i'ds with 2 spots; in the ARSILONCHE; ACRONYCTA. By Dr. M. Drattdt. cell above the median nervure an interrupted red-brown streak; along the submedian a whitish longitudinal streak from base to beyond the first third of the wing; from the apex a white streak extends obliquely to the angle of the cell; there are white internerval streaks in the subterminal; fringes grey intersected with brown. Hindwings brown, base whitish, dark nervures and white fringes. Thorax pale grey, abdomen white. Wing expanse 33 mm. Gafsa (Tunis) in November. This species is unknown to me, according to the description it might be a Guculliane something like Metlaouia oberthuri. S. nervosa F. — ab. rubrobrunnea Bird, is a variety occurring probably everywhere in palaearctic rubro- territory having the white forewings more or less suffused with red-brown; also the hindwings are red-brown hl 1,11,11 "■ along the median and reddish-brown beyond the cell. — ab. atrata Belling has quite black forewings from base airata. to beyond the middle, from there to the apex paler ochreous, veins lighter outlined with grey towards the margin contrasting with the dark ground. Hindwings deep grey. Bred from larvae from near Berlin. — subsp. argentea Splr. from the Altai is somewhat larger on the average and a purer white especially on hindwings. — argentea. expressa B.-Haas are specimens with a slightly more bluish grey-white colouration with a sharper and purer white expressa. or whitish-yellow basal streak and a similar mark from the disco-celluar nervure to the margin. Hindwings are black with pure white fringes. From Karagai-Tau and the Juldus region. S. splendida Stgr. — ab. allbicilia Bird, has the hindwings suffused with brown but with a white margin splendida. and similar fringes. Turkestan, Siberia, Corea, Thibet. This form is represented by the illustration inVol. Ill, a/l>irilia- 2 e; we are illustrating the name type therefore in this volume (1 d). S. sincera Warr. is pure white on forewings, veins outlined in very pale grey on both sides, sprinkled sincera. finely with black on the inner marginal half of the wing, more sparsely sprinkled in the upper half; a distinct black spot at the lower end of cell. Hindwings and fringes pure white. Underside white, forewings faintly tinged with grey. Body white, head and prothorax faintly tinted grey. Shaft of antennae white, pectinations rusty brown. According to a single $ from Baigacum (Syr Daria), caught in June. 12. Genus: Arsilonclie Led. A. albovenosa Goeze. — The name: degener Hbn. can no longer be considered synonymous and should degener. be now utilised for the somewhat smaller autumn generation with very pronounced longitudinal streaks on forewings. — ab. neomelaina Traub is a melanic form. Head and dorsum black-brown. Forewings coffee- neomelaina. brown almost black, veins light grey, base of wings grey; hindwings grey-brown blackened towards the margin, abdomen black-brown. This may probably be described as a melanic form due to an industrial environment because a number of the form were bred from larvae which Were obtained in the neighbourhood of Neustadt a. d. Hardt and the contaminated creeks in the surroundings. — ab. tristis B.-Haas is a darker form of ab. centri- iristis. puncfa with the grey-brownish ground colour of S. nervosa but darker and more unicoloured; it differs from cenlri- the ab. murina Auriv. from Sweden and Finland in that the veins are not powdered with white. From S. Russia puncla. (Gov. Saratov). — subsp. tanaica Alph. is described as the more frequent form of centripuncta which is disting- ianaica. uishable by a dark brown longitudinal streak on the fore wings which commences at the base and extends in the direction of the black discoidal spot, not rarely this expands widely which gives the insect a most pronounced character. It occurs in the entire district around the Sea of Azov. — subsp. cretacea Wagn. (1 b) is a recently creincea. described form from Anatolia with chalky white ground colour with minute dark scales distributed over the surface and with sharp black marginal spots. The longitudinal streaks contrast sharply from the dark ground colour. HindAvings and underside are also a purer white without the yellowish tone of the name form. — albo¬ venosa is widely distributed in the East as far as Japan and Saghalin. A. saepestriata Alph. is omitted by Warren. It resembles albovenosa and especially the v. murina saepesiriata. of same but it differs by the monotonous grey-brown hindwings. In murina the white veins on fore wings stand out from the brown ground but in the present species on the other hand straight bronze-broAVn inter¬ nerval stripes appear on a white ground. Described from a single $ of 34 mm wing expanse from Urga in northern Mongolia. 14. Genus : Acronycta Tr. This genus requires to be brought up to date. At present we do not consider the separation of the Chamaepora Warr. as justified as it was based solely upon differences in the larvae and of the 60 known Acronyctae so far all in all only 12 of the larvae are known, so that it would be impossible at present to assert whether the remaining species belong to this or another genus. On the other hand instead of Chamaepora we must introduce the old genus Craniophora Snell, which can be well separated from Acronycta and differs by a complete row of abdominal tufts, Avliilst Acronycta only has a basal tuft; the thorax in the latter is quite free of tufts whilst Craniophora has a separated tuft on the ACRONYCTA.

Besides this, veins 6 and 7 always have short stalks on the hindwings in Acronycta which is not the case in Craniophora. Great objection was taken to the alphabetical ordination in Vol. Ill which took no account of the relationship of the species to one another. As an exception we therefore have to alter the order and have chosen a new sequence. For this reason we are enumerating all the names again. Type of the Genus: A„ leporina L. Sect. I. Thorax covered only with scales: (Hvboma L.) A. hemileuca Piing. (1 b). To the insufficient definition it should be added that this species, which is closest to strigosa, is larger and with much darker and more regular reddish-grey coloured forewings ; in one specimen the discal area is paler; ordination of markings agrees with strigosa, a pale spot at the inner angle. Hindwings pure white only somewhat darker dusted at the apex with interrupted dark marginal line. Underside similar to strigosa , hindwings whiter. Palpi more densely haired, body sleeker. The illustration in Vol. Ill is not recognisable. A. phaedra Hmps. (1 b) is also very close to strigosa but generally somewhat larger; forewings grey- white sprinkled with black, black basal streak expanding to cuneiform mark before the antemedian line and continuing beyond same; both upper stigmata yellowish- white with dark centres and circumscribed by black; the posterior transverse line is only double on the costa, bordered with white inwardly, the anal dart-shaped mark behind same very heavy and distinct, blackish dusting above and below same. Fringes black and white checked. White hindwings are tinged with brownish-grey, darker at margin and with black marginal spots. Described from the Ussuri district; Kasakewitsch and Sutshansk. A. phaedriola n. sp. (1 c). From the same locality as the former, Sutshansk, occurring in June and therefore with no 2nd generation. Mr. O. Bang-Haas has kindly sent me a species which is very close to phaedra but only half the size of same and which is immediately distinguishable by its very dark grey-brown hindwings with much more distinct and pronounced angular postmedian and very distinct cliscoidal lunule. Fore wings narrower, apex more truncate, reminding one in this respect of the group of small A. niveosparsa and omihsiensis. Forewings similarly more darkly and densely sprinkled, the entire marking is much more diffuse and suffused whilst otherwise closely resembling that of phaedra. The space between the double transverse lines and the markings in the stigmata are not white as in phaedra but of the same colour as the ground. The basal streak is quite absent here whilst in phaedra it extends to the discal area even if diffusely and it more or less unites with the anal dart-shaped mark. Described from 2 AS ex the collection of 0. B.-Haas. A. strigosa Schiff. A. chingana n. sp. (T c). A pretty species which is fairly close to strigosa but is very striking by the heavily developed tuft on the abdomen on the basal segment. Forewings grey-white in discal area and a darker dove grey especially in the basal half; in basal third of the submedian fold a lively ochreous and the same colour fills the stigmata and occurs beyond the postmedian; markings otherwise very similar to those of strigosa but the black longitudinal streak is absent in the discal area over the sub median nervure ; the post-median is simple and of the same shape as in psi etc. Hindwings of the <$ white with finely interrupted marginal line, very faint discal lunule and traces of a darker postmedian line ; in the $ which is darker grey and more heavily marked, the hindwings are somewhat darker grey-brown, a narrow whitish border before the marginal line. Described from a pair kindly supplied by Mr. 0. Bang-Haas. A type from Inn-Shan, $ from Lin si hien, Chingan Mountains in eastern Mongolia. A. jankowskii Obth. (1 c). The illustration in Vol. Ill leaves an incorrect impression of this small species, for the outstanding white spot at the end of the basal streak is especially characteristic. A. cubitata Warr. I have no specimen of this before me. Forewings pale grey mixed with darker and shaded more darkly behind the outer line. A thick dark middle line forming an angle within the reniform stigma so that same is obscured ; sub-basal line indicated by 2 streaks at costa, the double inner transverse line, elbowed inwards on the 2 folds and touches the thick black basal streak ; the pale grey round orbicular stigma has a dark centre and is circumscribed by black. The blackish reniform stigma is circumscribed by black. The outer transverse line is almost vertical between the subcostal and uppermedian nervures, then bends inwards at a right angle below the reniform stigma, it is white and heavily bordered outwardly with black; the indistinct submarginal line is indicated by black cuneiform marks. Fringes black and grey. Hindwings impure white with yellow-grey cell spot, outer line and marginal band. Wing expanse A 32, £ 34 mm. From Chabarowsk (Ussuri); Pompejefka (in the smaller Chingan). A. carbonaria Graes. (= brumosa Leech). A. suigensis Mats.

(1 d) is a very small species reminding one of certain Erastria species. Bore wings niveosparsa. dark brown, sprinkled with white and black, all transverse lines fairly suffused or obscured, only indicated by small spots; orbicular stigma white with grey-brown centre, outlined in black on both sides, indistinct reniform stigma dark grey with black and white markings, space between the two stigmata darkened ; marginal area white sprinkled with small black spots ; a white longish spot on costa anterior to orbicular stigma. Hindwings grey, veins darker, head white. Honsho (Kyoto), also mentioned by Draeseke as from Szechuan. A. omihsiensis Draes. (1 d) resembles niveosparsa in outline, but is V^t'd larger. Forewings whitish omihsiensis. grey, subbasal line only distinct at costa : both transverse lines whitish bordered with black on both sides, most distinct on folds; both transverse lines are conjoined in the submedian by a fine curved line; the large round orbicular stigma is whitish bordered with grey on basal side and with grey centre, the indistinct reniform stigma similarly; the whitish fringes are checked with black between the veins. Hindwings grey-brown with faint broad median band and pale yellowish fringes. Omihsien (Province Szechuan). A. subornata Leech. — - brunnea Hmps. forewings are browner and less grey. The illustration in Vol. III. brunnea. pi. 3 f is a very bad copy according to Leech and quite unrecognisable. The species closely resembles rumicis on forewings. Unfortunately we have not been able to obtain a suitable type for a better illustration. A. pruinosa Gum. A. consanguis Btlr. A. Jozana Mats. (1 d) somewhat resembles consanguinis and also phaedriola, differing from same by jozana. the more brownish ground colour. Forewings grey- white, marbled with black and brownish; 10 small black spots on costa ; the small round orbicular stigma has a suffused dark centre and is circumscribed with black, the large reniform stigma has dark grey centre and is circumscribed with brown-black; below the median nervure a long basal streak, both transverse lines double with whitish between, anal dart-shaped mark narrow. The illustration from Matsitmura shows both longitudinal streaks conjoined in discal area by black at submedian nervure as in strigosa. Hindwings pale brown-grey, darker at margin with extinct postmedian and white fringes. Hokkaido (Japan). June and August. A. albistigma Hmps. (1 d) is a very large species from Japan with forewings sprinkled with grey-brown albistigmcc. and brightly contrasting white orbicular stigma of somewhat oblique elliptical form; the grey reniform stigma is outlined with black at sides and marked with white spots, the double postmedian is filled with white between subcostal and upper median and lower median and submedian nervines, the undulate subterminal is white. Hindwings light brownish yellow, veins and marginal area brown with indistinct curved postmedian. A. rumicis L. — ab. marginata Lambill. corresponds to the virgata forms with dark marginal area. — marginata. meridionalis Dannehl (1 d) from the S. Tyrol are more brightly marked summer forms with ochreous tone on meridio- hindwings. — suhriana Gillm. closely resembles marginata, but basal area is also adumbrated, discal area on . the other hand remaining light. — polonica Pruffer is not grey-black, but uniform dark brown with black polonica. shading without the inner marginal white spot. Hindwings dark brown like the forewings with wider marginal band. The following is probably synonymous: — priifferi Mast, with darker upperside of forewings without prufferi. the inner marginal white spot. — subsp. oriens Strd. (1 d) from Japan and V/.

According to Oberthur the race from Tunis is said to be somewhat darker again than mid-european specimens with less brownish being purer grey with spots and markings on paler ground. As against what has just been said under oriens Obertiiur says that specimens from Ta-tsien-lu are still paler and more whitish; according to this matters are not very clear; unfortunately I have no specimens of this pale nature from W. China at my disposal. A. lutea Brem. & Grey — ab. aurantior Strd. has deeper orange yellow hindwings. — leucoptera Btlr. is aurantior. not a separate species according to Hampson, but only a form of lutea having more whitish hindwings with only faintly yellowish tone. Both forms occur in east Asia. A. catocaloida Graes. Sect. II. Thorax covered with hairs and with hair-like scales. (Triaena Him.). A. psi L. To facilitate distinction between the 3 species psi, tridens and cuspis that are so similar, I psi. quote here, what Petersen so pertinently says in his Fauna of Esthland: “These 3 species are very easy to differentiate according to their larvae, whilst sometimes this is difficult with the imago. According to Heine- Supplementary Volume 3 2 10 ACRONYCTA. By Dr. M. Dratidt. suffusa. batnana. iliensis. tridens. asignata. variegata. radoti. incretata. decyanea. obscurior. suffusa. caliginosa. belgica. rosea. leucocuspis. brunnior. jezoensis. subpurpu¬ rea. mann the ground colour is the only distinguishing characteristic. In tridens it is reddish grey, in psi bluish grey and in cuspis grey- white. However it is very difficult to decide according to a single specimen and especially tridens and psi are difficult to classify, cuspis has the most pronounced markings and always dark hindwings, whilst in tridens 3 they are pure white and in psi 3 white with darkened veins towards the margin : in psi $ they are faintly dusted with grey. Further as Treitschke has laid down, cuspis often has the orbicular stigma circumscribed by a closed black ringlet, whilst in the other species it is almost always open towards the base. The 3 species are easily distinguishable according to the formation of the valves”. Further in psi the dart-shaped mark above the anal angle is nearly always intersected by a small streak which in its course extends into the fringes, whilst in tridens these two merge forming more or less one streak ; the latter is almost always of narrower wing formation. — suffusa Tutt is a very dark aberration; in the type the marginal area is especially dark, analogous to the hivirga form and also the basal area is somewhat adumbrated. — subsp. batnana n. (1 e) shows very distinct differences when compared with large series of european psi. The general impression is darker, especially of hindwings; the outer transverse band is uniformly thick throughout its course, whilst in psi it becomes faint between lower and upper median nervures; basal and anal dart-shaped marks are double as thick as in name form, the anterior striga is distinctly double. Algeria; Batna (Types in the collection of Draudt), Sidi bel Abbes, Messer, Ain Fazza. May to September. — subsp. iliensis n. (1 e) specimens from central Asia are very large, both transverse lines are very distinctly double, especially the posterior one is distinctly more dentate and strikingly brown instead of being black, further it is not so sharply marked but more diffuse. Ili territory, Types in the Pungeler collection in the Berlin Museum. A. tridens Schiff. see psi in regard to the differences. Spuler names a form without the anal dart¬ shaped mark: - asignata from a specimen from Carlsruhe. — variegata Strd. (= ab. 1 Hmps.) from England lias forewings more admixed with white, hindwings of 3 are white, veins tinged with brown towards margin. - subsp. radoti Le Cerf from Morocco is a more uniform and darker grey without light patches, only the orbicular stigma is lighter and more rounded, both transverse lines contiguous, of uniform width and with blunt scarcely perceptible dentations; the wide and long clart-shaped marks intersect the lines, the postmedian one is not shaded outwardly with brown. Hindwings scarcely darker than type. We illustrate a good specimen of virga Tutt (If). A. incretata Hmps. (= increta Btlr. nec Morris, intermedia Warr.) (1 f) is a large species being very similar to the two previous and differing from same by the more unicoloured mauve-brown suffused forewing: the orbicular stigma is open at toji and obliquely elliptical. A black curved streak extends from same to reniform stigma; hindwings of 3 white, veins and margin brownish, of 2 dusted all over with brown and indistinct post- median. Japan, Corea, W. China. Specimens from Saghalin are much smaller than those from central Japan. The name given by Hampson must be upheld, as it was published in March 1909, whilst Warren’s name was not given until May of the same year. A. cuspis Hbn. — ab. decyanea Strd. (= ab. 1 Hmps.) forewings dusted with faint brownish without bluish tone. — obscurior Strd. (= ab. 2 Hmps.) has forewings almost completely dusted with black-brown. Transitions are named: — suffusa Spul. with smoky grey forewings and caliginosa Schultz with smoky brownish fore wings. Actually suffusa as well as decyanea are the same as caliginosa , which should have a preference in nomenclature, as it is the oldest name; there is no scientific value in such fine differences. Such specimens are occasionally met with throughout Germany and Austria. — Specimens from Belgium are generally somewhat darker grey, more suffused, submedian with distinct yellowish green longitudinal streaks through and behind the cell, prothorax very often not intersected with black longitudinally, although among suffusa forms specimens do occur with black prothorax streak. The form, which is paler than the genuine suff usa is characteristic and deserves a separate name from the mid-german specimens: belgica /. n. (1 f). — rosea Trti. named from a specimen from Sardinia has fore wings with a sort of rose-red sheen, the black dart-shaped marks are boldly marked, both stigmata conjoined by a thicker black streak. A. leucocuspis Btlr. (T f) should be removed from the cuspis forms and separated as a genuine species, differing by the small round white orbicular stigma. — brunnior Strd. (= ab. 1 Hmps.) according to a 3 with fore wings suffused with black-brown and hindwings dusted with brown. A. jezoensis Mats, somewhat resembles cuspis but differs from same by the completely white hindwings. Forewings light grey with black markings; basal streak below the median nervure wide with a small mark branching off upwards and 2 downwards; both stigmata obscured, orbicular stigma with dark border outwardly, reniform stigma with dark border towards base; postmedian lined with white inwardly, intersected by the anal dart-shaped mark ; outer margin somewhat darker grey, small black spot marking between the extremities of veins, fringes white and checked with white. Hindwings white with black spots along the margin. From Hokkaido and S. Saghalin in July and August. A. subpurpurea Mats, closely resembles incretata and differs by the deeper red-brown forewings and the much wider and longer basal streak; both transverse lines are obscured and only clearly visible above the median nervure; the pale grey submarginal edged outwardly with black is relatively close to the margin, marginal area behind same somewhat darker. Hindwings pale grey with dark cell spot, postmedian and wider marginal adumbration with light fringes. Described from 2 33 from Sapporo, Hokkaido, Japan. ACRONYCTA. By Dr. M. Draudt. 11 A, sapporesisis Mats, from the same locality also closely resembles cuspis, differs however from same by the completely silvery white hindwings of A ; fore wings pale grey with heavier black markings; basal dart- shaped mark forked at end and with white edge outwardly below median nervure; both stigmata white, reniform large, brownish in centre with black outline inwardly, both conjoined by a black streak; the posterior transverse line quite extinct only indicated by 2 black marks on costa; the white subterminal line widely bordered out¬ wardly by a black- brown band; the anal dart-shaped mark with white border on lower edge,- white fringes with dark checks. Hindwings of $ more inclined to grey-white with narrower dark postmedian and some marg¬ inal dusting. Expanse of wings A 37 mm, $ 41 mm. Sapporo in June and September. A. orietttalis Mann related to cuspis, somewhat smaller on an average; ground colour is more whitish and more coarsely dusted with black; markings very similar to species named but the anal dart-shaped mark much finer and thinner. Pontus, Bithynia and Lydia. — subsp. galvagnii Schaiv. (1 g) has ground colour of deeper grey-black shade with boldly pronounced dentate lines of deep black colour. Herzegovina (Mostar). A. hercules Fldr. (1 g). We are giving a better illustration, the hindwings in the figure on plate 2 k were too dark. A. taurica Stgr. (1 g) should be separated from cuspis. It is certainly a genuine species, reminding one more of a small aceris; it has quite white hindwings with faint shading only in subapical area. Veins finely dark in marginal area. Forewings without the black streak between orbicular and reniform stigmata, the anal dart¬ shaped mark is delicate and does not extend to margin. Occurs at Lebanon in Syria besides in Asia Minor (Taurus, Hadjin, Zeitun). A. aceris L. — - candelisequa is a more lead grey form, whilst infuscata Haw. is more suffused with olive- brownish. Petersen mentions in his Fauna of Esthland a completely sooty black specimen, which seems to go beyond infuscata. — * asignata Hirschlce from a single specimen from Enzersdorf near Vienna is quite without markings on upperside, hindwings also without curved line. — In elineata Dujrane the black subanal streak is missing, the customary markings are more delicate than in normal specimens, the wings finely sprinkled with black. Described from Belgium. — subsp. judaea Stgr. (1 g) we illustrate a fine specimen from Palestine ex the PiiNGELER Collection. — calceata Dannehl (1 g) differs little from same, it has perhaps slightly more blackish dusting in inner marginal area and a slight yellow-grey tinge behind the postmedian; hindwings also slightly whiter. From the central Apennines. A. major Brem. — anaedina Btlr. is not purely synonymous, but designates darker forms, especially on hindwings, from Hondo and W. China. — - anaedinella Strd. (= ab. 2 Hmps.) with extinct basal and postmedian markings. From central and W. China. Probably this name is synonymous with defigurata Warr. A. alni L. — ab. nigromaculata Gelin has a more or less widely blackened marginal area on hindwings and represents a variety that apparently occurs relatively frequently in W. France. — ab. eothina Dannelil (1 e) from Drautal and Klagenfurt is heavily suffused with rose. From series of these specimens it would appear that 5% of the dark rosy specimens have very heavy black marking and orbicular stigma is always missing. The rose colour however soon fades in the collection and turns to reddish yellow. A. auricoma F . — The somewhat smaller and paler Spring form is separated as — vernalis Frings; it is the commoner form that occurs from April to June, whilst the summer generation is only a partial brood in July and August. pepll Hhn. (1 h) is a dark, small and single brooded form from the North and the Alps. The larva of this latter form seems to have a constant variation from that of auricoma as the warts are white instead of being red. A. schwingenschiissi Zerny (1 h) is very close to auricoma and the arrangement of the markings is the same. The ground colour however is a pure iron-grey with faint violet tinge; transverse lines and stigmata distinct and deep black; the black longitudinal streak extends from the basal edge of reniform stigma to the margin, the black central dot is absent from the longish orbicular stigma. Hindwings pure white with veins darkened towards the margin. It is less coarsely scaled than the somewhat similar euphorbiae. It occurs in June in Aragon and Andalusia. A, pulverosa Hmps. (= pruinosa Leech nec Guen.) (1 h) is also like auricoma-, it is more besprinkled with brown, the antemedian transverse line is less distinct, the white orbicular stigma is obliquely quadrate and not round; the posterior transverse line is distinctly double, especially at costa. The marginal area is very dark on the dusky hindwings and an indistinct postmedian is present. — fuscosuffusa Strd. (= ab. 1 Hmps.) has forewings more heavily suffused with black-brown. Japan, N. China. — - subsp. sachalinensis Mats, has a more slender and smaller body; wings much paler, only a quadrate mark between the stigmata which is distinct and darker; a further paler spot between postmedian and reniform stigma, so that the inner part of the postmedian diffuses here; hindwings pale grey with dark discal spot and submarginal band.

According to Petersen these are the characteristics at least for the main type form; on the other hand it is very difficult to distinguish certain specimens of the variety suffusa from pepli, as pepli (at least as far as concerns specimens from northern localities) also has a very indistinct subterminal line; only the valves of the $ show considerable differences. — scotica occurs as an aberration also in N.

Specimens from Uralsk and Sarepta and Asia Minor (Konia) are extraordinarily pale, quite like a pale aceris and probably correspond to — albidior Wagn. described from the Udine. — ab. pulla Strd. described from Norway is suffused with black-brown on body and wings, only the area of the orbicular stigma remains white. A melanic form that probably also occurs elsewhere and which may be deemed a transition to nigra. — nigra Shaw. (= aethiopa Krul.) (1 i) is the extreme form of the above from Moscow and Wiatka. It is a form completely suffused with black with traces of light markings and an occasionally more prominent white postmedian line than is shown in the illustration, thorax black and abdomen dark. — ab. schlumbergeri Schultz is established from a pathologically varying specimen from Silesia. Markings are diffuse and subterminal line is closely approximated to margin, the area anterior to same being very wide and pale. Hindwings whitish with a faintly dentate dark antemarginal line immediately before margin. warpachowskii Krul. (1 h as albidior) has forewings more grey- white with delicate black, partially disrupted markings, the light patch behind the reniform stigma almost quite white; the discal area sometimes lighter than the rest of wing surface, only inner marginal area darker, the transverse lines more distinct on the pale ground. E. Russia; probably the form is identical with albidior and could then claim priority. A. tiena Piing. (1 i) is a large dark species, closely resembling dark specimens of megacephala, but apparently still more closely related to euphorbiae. Larger than the latter, forewings wider, darker and more brownish, underside suffused with black, only marginal area and costa pale brownish grey, markings of forewing indistinct similar to euphorbiae. Alexander Mountains, Hi territory, W. China (Moupin). A. euphorbiae Schiff. The type form, occurring northwards to the southern part of the Baltic Provinces, is always more smoky grey, the northern and alpine form — montivaga is more blue-grey ; the latter is generally somewhat larger . According to Hampson the much older name: obscura Strom, should be utilised for the latter form. — ab. parisiensis Gulot is a specimen darkly suffused with smoky black in which only the transverse lines retain a somewhat lighter shade and which is analogous with ab. melaleuca of leporina. — myricae Guen.

Very close to same are also very pale, more inclined to grey-blue specimens which form a constant local form in the Abruzzi mountains: — apennina /. n. they are delicately and yet distinctly marked. — korlana /. n. (1 i) is possibly a genuine species; it is small, slender, margin oblique, ground colour coarsely sprinkled with black; from Korla, type in the Pungeler Collection. A. abscondita Tr. (= euphorbiae H.-Schdff.) (1 k) is certainly a genuine species, smaller, somewhat darker, markings rather more diffuse, the elbowed line scarcely dentate. The species closely resembles certain myricae, but always has a wider and more truncate wing contour and more glossy scaling. The larva is constant and varies from euphorbiae by the absence of the red oblique band on the 2nd segment. It feeds on heather. N. Germany, Lapland, Russia. — ab. faseiata Hannemann based on a specimen from Berlin has a black discal band on forewings. — subsp. glaucoptera Petersen (1 k) from Esthland appears to be a constant form there; smaller, dark blue-grey with scarcely distinguishable stigmata, hindwings and abdomen blackish grey, strikingly darker than in german specimens of abscondita. A. leporina L. The expansion of the black markings varies in typical forms. In ab. bimacula Maass. ( 1 k) there are only 2 black spots, one above the other, in jilace of the reniform stigma, in ab. alba Gillm. wings are uniform white without markings. - bradyporina Tr. according to the researches of Gillmer is the english form that is dusted with black, with darker marginal area, and should be classified with semivirga. — leporella on the other hand is not sprinkled with black, but uniformly dusted with grey. — ab. melanocephala Mansbr. (1 k) is a bradyporina with heavier black markings and entirely black head and thorax; from Warrington in England. — subsp. leucogaea Stick, is similar to semivirga, but only the outer part of margin is grey; in this form the basal area is also grey, the discal area whiter, both transverse lines, especially the posterior one very sharply marked and continuous, dart-shaped marks retrogressive. Based on a bred specimen from Schwerin. - subsp. (et ab.) grisea Cochrane from England, as an aberration also from N. Germany and Denmark, is a bradyporina without dark marginal area, with bold markings, which can even closely resemble a pale psi, differs from same however by the absence of the orbicular stigma and the very delicate basal streak. — ab. melaleuca Culot (1 k) is an extremely melanic form, uniform dark grey-black, only the outlines of the two transverse lines remain light. From a specimen from Osnabriick. — The species is found as far south as Bilbao in Spain and N. Italy, eastwards in the form leporella as far as Saghalin. A. senica Ev. ( ? — literata Brem.). I have not obtained any fresh information in regard to these species including the ab. x-signata Stgr. that possibly belongs thereto. In appearance they remind one more of a Graptolitha ( Lithophane ) in the relationship of lavula and do not show any resemblance to any other A crony eta ; senica has in fact already been classified by its author to Xylina. A. omorii Mats, is compared by its author to literata Brem. I cannot see any resemblance from the illustration and would therefore more readily classify same near to strigosa. Forewings grey-blue with somewhat blackish markings: the short basal longitudinal streak is conjoined with the double antemedian, which bends in a sharp angle below the median nervure; the oval grey- white orbicular stigma has a black border on each side, the large grey reniform stigma is somewhat darkened in the centre ; the postmedian is only visible between the costa and median nervure; subterminal line somewhat curved outwards, dentate on lower and upper median nervures, a fine anal streak on the submedian fold extending to margin; anterior to margin traces of a light undulate line; fringes white with fine dark intermediary line. Hindwings glossy white with fine black-brown marginal line. Wing expanse 34 — 37 mm. Hokkaido and Honsho in the middle of June. 15. Genus : €raniophora Snell.

Tyrol, which seems to me to be effusior. close to troni is named effusior Dannehl (1 1) a type of which we can illustrate thanks to the author in the same way as the following two: it appears much brighter owing to an increase in the white which is admixed with roseo- rose and green hues transforming the black markings into light grey and grey olive. — ab. roseoradiata Dannelil radiata. ^ j) is a form in which the rose coloured interspersions form 3 rosy brown or violet longitudinal rays from base viburni. to margin; this is a rare form from the S. Tyrol. — viburili Dannehl (11) is the opposite extreme, uniformly mouse-grey with a very narrow darker transverse band ; the large whitish spot in the outer area scarcely lighter than ground colour. Fairly common among the summer form in S. Tyrol and apparently very similar to sundevalli. G. obscura Leech. 16. Genus: Tlialats® Wkr. This genus, which includes one african and several indo-australian forms, is closely related to Acronycta but differs chiefly by the presence of a small horny projection on the clypeus with raised edge. Only one species touches palaearctic territory: sine ns. Th. sifiens Wkr. The small grey-white species was classified in Vol. Ill under Acronycta, but actually belongs here. It reaches palaearctic territory in W. China and is described more fully in Vol. XI, p. 36 and well illustrated there on pi. 5 d. 2. Sub-family: Bryophilinae (for Metachrostinae). We are utilising the old name: Bryophila instead of Metachrostis, because Treitschke described it 2 years previously to when Hubner established his Metachrostis and Warren has meanwhile altered his classi¬ fication in the indo-australian part accordingly. 19. Genus: ilryoplilla Tr. pineti. B. pineti Stgr. (2 a) cannot be recognised by the illustration in Vol. III. This species reminds one most readily of the Geometridae Pachycn. hippocastanaria in colour and markings but it has wider wings. This very rare species was hitherto only known from a few specimens from Andalusia, Castile and according to Korb from boursini. a single specimen from Aragon (Teruel) but has lately been found in a special form : — boursini Gleu also in the Htes Alpes. In these the forewings are grey, dusted with black without stigmata and the yellowish spot at close of cell; transverse lines are only indicated by spots on costa; a median suffused shadow stripe is very distinct, the elbowed line is more distinct, whitish, bordered with black outwardly, subterminal line radially dentate on veins. Hindwings dusky grey. Captured in July. B. albonotata Stgr. belongs to the Genus Ghytonix (compare there). petraea. B. petraea Gum. (2 a) has meanwhile been frequently captured in Spain and Mauretania (Batna, Guelt es Stel, El Kantara, Maafa, Lambessa) in September. It is a very variable species: pale grey, almost without BRYOPHILA. By Dr. M. Drattdt. 1 5 markings, a bright grey with heavy black markings, some such a dark grey that the markings can scarcely be discerned; sometimes, as in the specimen illustrated, a black-brown broad discal band is created: — transversa /; nov. (2 a). — coiltristans Led. (2 a) is the eastern form which also is very variable; it occurs as well in forms with darkened red brown discal area — mediobrunnescens Strd. corresponding to provincialis C'ulot. Also with bold black longitudinal streak submedian from base to elbowed line and indistinctly beyond same like in striata of raptricula: — ramosana /. nov. (2 a). The species is always easily recognisable by the coppery reddish hue of hindwings. contristans is found in Kurdistan and Syria, besides in Greece and Asia Minor. — hoerhammeri Schaw. (2 a) recently described from Corsica makes a different impression. Somewhat larger, the grey-brown of forewings darker, less scaled with brown so that the white submarginal lines are suffused by white, only the small black dart-shaped marks and the white anal spot remaining; the two middle transverse bands bold, the area between being subdivided by a broad black transverse band; the basal dart-shaped mark is absent, the brownish scaled stigmata circumscribed by black. Hindwings darker outwardly, margin blackish almost to the middle. Corsica (Evisa). B. divisa Esp. (= pomula Blch., raptricula Hbn.) like most of the Bryophila is subject to the most astonishing variations. The name divisa denominates the more northern forms which are always darker, more black-brown. — oxybiensis Mill. (2 b) is the somewhat smaller and greyer southern form which occurs in the Provence, Spain, Sicily, Turkey as far as Turkestan. Specimens from Palestine and further east through Persia to Aksu and the Thian Shan are considerably more grey: — palaestinka Strd. (2 b) from Jerusalem is grey- white on forewings, finely striped with black on the veins. — deceptricula Hbn. denotes darker specimens with rich fuscous or fulvous admixture. Small specimens of this from S. France, Spain and Algiers are : — provincialis Culot ; here the basal area and inner margin of forewing are violet grey, the discal area of costa black-brown, the outer half of cell and beyond red-brown as far as the margin. Mauretania, June August. — persica Strd. (2 b) denotes quite similar specimens, which are larger and paler grey-white originating from Persia, the Urals, but also occurring in Hungary and Croatia as far as Irkutsk. It should be stated that Spanish oxybiensis very often have this yellow-red longitudinal streak from base to margin. Rothschild denominates unicoloured grey specimens as ab. unicolor (= grisea Dannehl ) (2 b). Specimens of oxybiensis approaching the type in regard to colouration are named nifitincta Rothsch. — ab. disfincta Rothsch. has a black basal %rd below the median fold. An extreme form of this is basimaculata Trti. (= illustris Dannehl) (2 c); this is a striata form on which the entire inner marginal area belowr the black longitudinal line is darkened with a dark oblique streak up to the apex. Very dark specimens are named ab. saturiator Rothsch. bryophiloides Rothsch. denotes small specimens with narrow wings which are grey-brown with almost extinct markings. — Of striata (2 b) we are able to illustrate a fine specimen ex the Pungeler Collection. — tibetica Strd. (— ab. 8 Hmps.) (2 b) from Lob-Nor are similar to striata but the two transverse lines of fore wings stand out strikingly prominently black. Titratt has created a number of new names for specimens from Cyrenaica: — marmorata Trti. a dark form with whitish admixture at base of inner margin behind the antemedian and subterminal lines at costa and inner margin. — sarrothry- poides Trti. (2 c) are ash-grey specimens with numerous black spots. alboscapulata Trti. is a basimaculata with dark costal area and a large whitish basal mark on costa. — dilutata Trti. is grey-white with large trapeziform red-brown costal mark admixed with whitish outwardly. — trisigiiata Trti. is similar but also with a red-brown basal innermarginal spot and dark marginal area. - degenerata Trti. as the former but without the dark margin and the spots more black-brown. — acceptricula Trti. is ash-grey with large red-brown costal spot that is trapeziform and with bold black anal streak. — - variegatula Trti. is similar to degenerata but the black-brown colour is more extensive, so that the white fades away. All these forms are from Bengasi, but also occur occasion¬ ally elsewhere. B. dolopis Hmps. (2 c) closely resembles a large raptricula and it may be that it should only be classified as a subspecies. Basal and anal j/pd of the postmedian area are light grey, the latter with a fine white crescent above the inner margin and behind the outer transverse line. Hindwings reddish brown. Certainly as variable as divisa. — paliidior /. n. (2 c) denominates specimens without the dark trapeziform mark on costa. — striata /. n. (2 c) the corresponding form with the black submedian longitudinal streak. This larger species has hitherto apparently only been found at Askabad and Kushk. B. raptriculoides Trti. (2 c). This species, that is described from Sardinia, closely resembles the divisa-raptricula ; it is larger and bigger, the wing contour being wider. Ground colour dark ash-grey with faint greenish tone; the large dark brown spot which encloses the orbicular stigma, is not diffuse but sharply outlined, glossy; the markings are delicate but sharp and distinct, a fine white crescent behind the postmedian line in anal area. Hindwings grey-brown not whitish, head and scapulae pale grey. — mediostrigata Trti. represents the form striata of divisa with a black longitudinal submedian streak, which intersects the white anal crescent. - marmorata Trti. (2 c) is much darker black-brown with large white basal spot, the white anal mark considerably more extensive and a white patch also at apex.

By Dr. M. Drattdt. B. palliola Bkh. (= fraudatricula Hbn.). The name given by Borkhausen has a precedence of 10 years and can therefore claim priority as has quite correctly been pointed out by Hampson. It occurs throughout Asia to the Amur and Ussuri (according to the Pungeler Collection) and is also found on Japan and Saghalin. B. simulatricula Guen. (2 d) is certainly a genuine species, as Pungeler among others was able to prove by breeding from the ova and it is not the same as palliola. It is somewhat smaller, narrower with more acute wings, more whitish and coarsely sprinkled with ashy grey, the markings thereby become more nebulous and less distinct. Especially specimens from Algiers often have a black longitudinal streak at inner margin of forewings, the region round the reniform stigma is sometimes whitish, ground colour variable, ashy grey to reddish yellow-brown. Hindwings quite pale whitish, dusted with grey with fine discoidal lunule and grey- brown postmedian, subterminal and marginal lines. From the Valais (Martigny), Spain, Italy and Mauretania from August to November. The larvae feed on Juniperus phoenicea. — f . zobeli Heinrich is larger than specimens from the Valais, not grey but whitish with blackish markings; ground colour of fore wings much darker, more blackish than normal light grey specimens. Hindwings are paler and have 2 narrow marginal bands. Described from Digne. B. pallida Beth. Baker (2 f) described as a local form of palliola but with Rothschild, I consider same to be a genuine species. Smaller than the species named, it is of much paler colouration with decidedly shorter and wider wings. Fore wings pale greenish grey, the black transverse lines and the spot in the middle of discal area as there, the black anal streak is absent; both stigmata are finely circumscribed by blackish, more distinct than in palliola, reniform stigma filled with pale grey. Hindwings very pale grey with distinct black postmeclian line and dark grey discal spot. Described from Egypt (Alexandria), also from Algiers, Tunis and Morocco. B„ albomaculata Rothsch. ( = albimacula Oberth.) (2d) is not allied to simulatricula. Head whitish, thorax grey and olive green, abdomen olive brown, grey at extremity. In typical specimens forewings are light grey, more or less dusted with yellowish or glossy olive bronze with a black, twice interrupted longitudinal streak over submedian nervure from base to margin; basal % rd admixed with white, the very large reniform stigma white, behind same a curved darker line which is bordered with white over the inner margin; marginal area heavily mixed with white with a dark spot in middle of margin. Hindwings grey-white, $ darker, greyer, the posterior transverse line wider with larger white spot below median nervure. Hindwings grey-brown. Algiers in August, September. A form found more often in W. Algeria: — grisescens Rothsch. is darker grey without the bronze yellow dusting, the reniform stigma is not always white. B. anaemica Hmps. is held by Rothschild to be an extreme form of albomaculata. Forewings white with brown hue, partly yellowish and sprinkled with black; a black basal streak to elbowed line, which like the inner line is very indistinct blackish; both upper stigmata are small brownish spots in faint whitish ringlets; behind the oblique subterminal line there are short black streaks above and below discoidal and median nervures. Hindwings faintly brownish with white fringes. Expanse of wings 26 mm. Batna. B. pannosa Wilem. Of this I have no specimen before me. Fore wings impure grey-brown, behind the middle with whitish costal spot, apex intersected by a whitish streak, whitish scales along costa ; 3 irregular darker transverse lines, each commencing with a small black costal spot, submarginal suffused. Hindwings darker grey-brown. Wing expanse 19 mm. Japan (Hondo). B, miltophaea limps. (2 d) is a highly variable species. Forewings with yellowish ground densely scaled with rosy-red, somewhat like Antitype argillaceago, interspersed with dark lead-grey scales or quite unicolourous dark lead-grey: — plumbina f. nov. (2 d) only with a few brick-red scales along the transverse lines, the dentate transverse lines indistinctly double; both upper stigmata with dark centres with feeble lighter ringlet and narrowly circumscribed by black, orbicular stigma elliptical, reniform stigma constricted, also a dark claviform stigma indicated; subterminal line faintly paler. Hindwings light yellowish brown, margin darker with white- yellow fringes. V/. Turkestan, Alexander Mountains. B. piingelen n. sp. (2 d) resembles the former species somewhat in form and size and is classified in the Pungeler Collection in the Berlin Museum under miltophaea, but I consider same a separate species. Fore wings are somewhat narrower and more elongated on the average, pale yellowish grey, coarsely sprinkled with blue- grey in the basal, discal and marginal areas, the 3 stigmata with darker grey centres and heavily circumscribed by black, the very large claviform stigma with darker centre and conjoined to the orbicular stigma; both transverse lines much less distinct than in miltophaea in comparison to the irregularly blue-grey ground colour. Hindwings much lighter whitish yellow-grey, slightly darker at margin with white fringes. Type from Aksu in the Draltdt Collection, further specimens in the Museums of Berlin and Munich being collected by Ruckbeil, also from Mustagata, Yarkend and E. Turkestan from Chamil Kami. B. vilis Hmps. (2 d) is a larger species, forewings with whitish ochreous ground colour densely sprinkled with black, discal area almost completely black, the indistinct transverse lines whitish and feebly dentate; orbicular stigma round finely lightly circumscribed, reniform stigma scarcely discernible; the light subterminal line very indistinct. Hindwings whitish, with faint brownish tinge, darker at margin with white fringes. The $ is more uniformly dusted and sprinkled with black. Merv (W. Turkestan). Pull. 4. VII. 1931. BRYOPHILA. By Dr. M. Dratjdt. 17 B. thamanaea limps. (2 d) belongs similarly with the preceding to the millophaea group. Forewings thamanaea. ochreous whitish, peppered with black especially in basal and discal areas, the brown inner transverse line edged basally with ochreous white, the elbowed line double; both upper stigmata large with black centres and pale edge finely outlined by black. Orbicular stigma round, reniform stigma 8-shaped, instead of a subter¬ minal line small blackish spots on the inner side. The whitish hindwings with brownish tinge and traces of a postmedian line and a discal spot. Persia, Shakuh. B. hampsoni sp. n. (2 e) is as large as miltophaea with still wider wings, quite milky white adumbrated hampsoni. to a grey-black in basal area and widely in disc, sparsely peppered with black scales in front and behind the shade. Transverse lines only indicated by colour contrast, the posterior line extends in a wide arch around the reniform stigma which has a somewhat dark grey-black centre and is edged with white. Subterminal line faintly dentate, indicated by somewhat denser blackish scaling, a larger spot at costa. Marginal area scarcely more densely peppered, small spots at margin. Hindwings thinly scaled somewhat darker in shade than ground colour of forewings with darker discal lunule and marginal nervures. North Alai (Ispayran), £ type in the Pungeler Collection ; Hampson had the type before him and assumed it belonged to a new Genus, but I prefer to classify same here. B. plumbeola St.gr. (Vol. 3, p. 20, pi. 4 c). — ab. syriensis Sir cl. (= ab. 1 Hmps.) has the postmedian syriensis. area of forewings with the exception of costal and marginal areas rather more yellowish. Syria. B. albiceps sp. n. (2 c) is a somewhat more slim, narrow winged species. Head and upperside of palpi albiceps. white. Forewings whitish densely dusted with grey-black with the sole exception of the transverse lines which remain white. Stigmata in median area therefore barely prominent; inner transverse line wide, elbowed line of usual shape in a wide arch around the reniform stigma, concave outwards on the submedian, projecting in a dentation along nervure 1 ; subterminal also whitish, fringes intersected by a dark line. Hindwings pure white. Type in the Collection of 0. B.-Haas. According to a $ from Garni, Peter the Great Mountains, captured in June. B. protecta sp. n. ( Bung . i. 1.) (2 e). Under this name there is a specimen in the Pungeler Collection 'protecta . that is somewhat like albiceps, grey-black peppered with white and with white transverse lines which are rather differently shaped and more sharply outlined by black. It also has brownish grey hindwings. Lagodechi. B. eucta Hmps. (2 e). Head and thorax whitish with darker admixture. Forewings ochreous-whitish eucta. peppered with brown-black with indistinct blackish transverse lines, the inner one vertical, slightly undulate, the posterior finely dentate of usual form, the discal area between same blackish, the stigmata therein with indist¬ inct pale edges; orbicular stigma round, reniform stigma elliptical; the indistinct pale subterminal line with black- brown inward edge. Hindwings white with brownish margin and white fringes. Persia (Urmiah); W. Turkestan (Askhabad). B. glaucula Stgr. (= fraudatricula Leech nec Hbn.) (Vol. 3, p. 20, pi. 4 c) (2 e). We are giving here glaucula. a good illustration of this rare species in the Berlin Museum from the Pungeler Collection. B. labecula Led. (Vol. 3, p. 20, pi. 4 c) (2 a). We are giving a further illustration from a perfect specimen, labecula. B. granitalis Btlr. (2 e) is omitted. It resembles a large algae in the markings, basal area pale grey; granitalis. the outer margin more oblique than in algae, more resembling raptricula ; middle area black admixed with chestnut brown, narrow at costa and inner margin, very wide in cell by the large arch around the reniform stig¬ ma; this as well as costa and inner margin pale grey subterminally and as far as margin; centre of margin reddish brown; above the submedian fold a heavy black angulated streak between the postmedian and anal angle. Hindwings grey-brown. The species is closely related also to glaucula, but is specifically different; the latter is darker and has no pale grey basal area. E.

According to 6 specimens in my collection from Haifa — rectilinea Warr. should also be classified here as an extreme pale grey form of ravula — ex- rectilinea. ceeding grisescens ; very variable, discal area occasionally faintly adumbrated, in one specimen the inner trans¬ verse line expanded forming a blackish antemedian band. In Portugal only a unicoloured dark, almost black form occurs: — ab. unicolor Spul. — ab. ravulana Strd. (= ab. 3 Hmps.) resembles vanclalusiae but has a rusty red antemedian area on forewings. Syria. — subsp. tatsienluica Obth. is a large race, the black inner transverse line on forewings more rounded, with 2 black longitudinal submedian streaks, a short one before the inner transverse line and a longer one from the postmedian to margin; stigmata as in ravula, similarly hindwings; ground colour of forewings dark grey, rufous admixed with whitish and black.

Hindwings white with grey discal lunule and 2 shadow bands before the margin. Portu¬ gal. Type in the collection of B.-Haas. Held by Pungeler to be an algae form, but same seems very strange when placed next to it. aerumna. B. aerumna Culot (2 f) resembles a small grey algae, forewings quite pale olive-grey, basal and dis¬ cal area adumbrated grey-black, the latter only at inner margin and along the edges of the two transverse bands adjoining same; stigmata with fine white edges, slightly darker; submarginal area paler, almost white, fringes red-brown. Hindwings paler grey than forewings, almost whitish with grey discal spot and arcuate often indistinct submarginal.

Besides occuring on Madeira and Tene- riffe it also occurs on the other small volcanic Islands. The larvae are found in April under stones, they are earthy grey with a few long black bristles and prepare a firm reddish cocoon in which they remain unchanged still in June. B. roederi Stfs.

They arc small amasina. and pale, of the same colour as perla with grey-brown basal, discal and marginal areas. B„ burgeffi sp. n. (2 g) is a small and pretty species, reminding one of muralis. Ground colour is a buryeffi. very pale greenish yellow; delicately and sparsely marbled with black in the somewhat chalky scaling; markings very finely outlined with black; an incomplete double subbasal, a double antemedian consisting of 3 large archs; the intermediate area somewhat more heavily peppered with black and situate therein the round dark orbicular stigma with black centre and the pale reniform stigma with concave inner edge towards the base. Between the two stigmata there is a circular paler and less speckled area which gives the impression of being a pale round stigma ; the edge of the claviform stigma is also indicated by a dark streak to the dentate double postmedian; the subterminal generally only outlined as the dark edge along the unspeckled marginal area; the white fringes have dark checks with black marginal streaks before the pale patches. Hindwings white, veins narrowly dark, with black marginal line and blackish disca! spot, a fine postmedian and antemarginal, the latter heavier towards anal angle, in one specimen expanding to a blackish band.

Head and prothorax delicate green with a few blackish spots and streaks, muscicolor. abdomen grey. Forewings delicate green with black and white markings; basal line does not extend to inner margin, both median transverse lines fine, distinct, velvety black with fine white edges facing one another; orbic¬ ular stigma small, sharply outlined, filled with delicate green with white ringlet ; reniform stigma large, coloured as the orbicular, both conjoined basally by a fine black and white streak, the large claviform stigma touches the orbicular; beyond the inner line 3 indistinct white spots: a large one at inner margin, a smaller one in the middle and again a larger one before the apex; marginal area beyond same a delicate green with a marg¬ inal line of black, inwardly white marginal lunules; fringes black, white and green. Hindwings dark, paler towards base with faintly indicated discal spot and black and white checked fringes. Wing expanse 30 mm. According to 1 <$ caught in July on the Kasyr Ssuk river. The type is unique and is placed in the Lenin¬ grad Museum. Filip jef deems same synonymous with Valeria sauberi Graes. B„ maeonis Led. (Vol. 3, p. 21, pi. 4 h) (2 h).

Similar specimens are to be found in the State centralis. Museums of Berlin and Munich. B. perla F . and perloides Guen. (Vol. 3, p. 21, pi. 4 g). These are a difficult problem. I am of the same perla. opinion as Spuler that perloides and perlina Stgr. are identical, whilst I consider pyrenaea Obth. to be a gen- verloides. uine species, chiefly because it is slightly larger on an average with sleeker and more pointed wings occurring next to the small perla forms flying in Spain. We have to enumerate the following forms of perla, besides the small perloides, which are sometimes suffused with reddish yellow and always have the same wing contour with truncate apex and occur in S. Tyrol as well as in Spain: — ab. dufranei n. n.

In Vol. 3 of this work, pages 23 onwards, W. Warren followed when dealing with this subfamily the classification of Sir G. F. Hampson in Vol. 4 of the Lepidoptera Phalaenae of the British Museum. He made however some drastic alterations grouping for instance Hampson’s Genera Euxoa and Feltia in a single Genus Euxoa and also the Genera Agrotis, Epipsilia and Lycophotia in a single Genus Rhyacia. In accordance with the present state in the study of the Agrotinae neither the first classification by Hampson, nor the second by Warren can be retained. This especially on account of the importance now attached to the structure of the male genital organs which was only partly taken into consideration by Hampson, but not at all by Warren. Therefore quite a new subdivision has become necessary. The subfamily of the Agrotinae doubtless belongs to the most difficult and complicated of all the Noctuides and a great deal of research work will still be ne¬ cessary to introduce perfect clarity into the sometimes very confused state of affairs. The following classification of the Agrotinae therefore is made without any claim to absolute correctitude or completeness and it is merely an endeavour to make a record as far as is possible of the present position of this family. Consideration has been given to the question of variations and races in those sjzecies where they actually and constantly occur and these are enumerated as “v.”. On the other hand on principle the author wishes to resist introducing a list of the innumerable denominations for aberrations. He is firmly convinced that only immeasurable confusion will be produced by this absolutely unnecessary denomination craze and that it is the duty of every serious entomologist to oppose same. This without in any way deprecating the importance of the interesting study of aberrations in relationship to possibilities of variation in any given species. Most of the Agrotinae vary very considerably among themselves, in many species the degree of variability is so great that among a series of hundr¬ eds of specimens there are scarcely two that can be said to be exactly identical. Only at the special wish of the editor the aberrations that have been newly denominated since the publication of the main Volume, have been enumerated, partly because this was initiated in the main Volume and partly to give our read¬ ers an opportunity of knowing what is intended by these denominations. The <$<$ genital organs, the structure of which is a most valuable help in differentiating the Genera rather than the species, have been examined by other authors and myself covering the greater majority of all the hitherto known palaearctic Agrotinae. In such cases where it has been impossible to make an exami¬ nation or where it cannot be decided with certainty that a particular species actually belongs in a relative Genus, I have placed a question mark behind the name of the Genus, thus E. (?) carthalina Christ. The antennae of the Agrotinae are very varied in formation. Their construction, whilst being impor¬ tant for a systematic classification, is not always proof of a close relationship of particular species or the reverse. Often in the same Genus, they differ exceedingly, as of course also occurs in other Genera of the Noctuides (compare for instance Valeria oleagina and jaspidea). For purely practical reasons and because this work is essentially a supplement, I have retained Warren’s, respectively Hampson’s subdivision into Sections. I must however lay stress on the fact that this subdividing into sections is often very difficult with the very great diversity in the antennae and it should not be accepted as absolutely final. The subfamily of the Agrotinae is mainly to be recognised by the presence of 3 charateristics, each of which is of equal importance. The first is the naked eyes, the second the absence or stuntedness of vein 5 of the hindwings, the third the jzresence of various spurs on the front, middle and hind tibiae, or on one EUXOA. By Dr. A. Corti. 2?, of these tibiae. In the Euxoa and Agrotis (Feltia) all the tibiae have spurs, the front ones very stout. Then follow those Genera in which the tibiae also all have spurs, but the front tibiae have much weaker spurs than is the case in Euxoa and Agrotis (Feltia). Then follow those having no spurs on the front tibiae, then those with spurs only on middle and hind tibiae and finally those with spurs only on the hind tibia. The formation of the frons is of great importance in the systematic subdivision of the Agrotinae. The cly- peus is either glossily smooth, or even and rough or with a protuberance that often varies considerably in its form in one and the same species having a crater-like or wart-like formation. This formation is sometimes absent as a rule (as for instance in ypsilon Bolt.) or more rarely (as for instance in exclamationis L.) Whenever it occurs it offers a valuable means of diagnosis together with the other characteristics. These clypeus pro¬ cesses are most strongly pronounced as a rule in the species of the Genera Cladocerotis, Euxoa, Agrotis ( Feltia ) and Dichagyris. In regard to the biology of the Agrotinae, same is without a doubt of great importance for a syste¬ matic classification of this subfamily. Through the nature of a comprehensive work such as we have under¬ taken this question can only be lightly touched upon. The ova of the Agrotinae are of very varying construc¬ tion. The most primitive oldest forms in my opinion deposit simple, irregularly shaped, unicoloured, more or less faintly ridged ova, either in batches next to or over one another. This chiefly concerns such spe¬ cies and Genera (Euxoa, Agrotis (Feltia) etc.) whose larvae are typical subterraneous larvae. The ova of the other species are globular, oval or gourd-shaped, heavily ridged, with spots or with coloured zones of all possible colour combinations, either in direct rows or adjoining areas. The larva can be divided into at least two large groups. The first group covers the typical sub¬ terraneous larvae, that pull their food into the earth, should no more be present below the surface. These are heavily formed caterpillars of grey to reddish or brown colour with relatively little marking, short bristles, which in the very young stages bear curious small clubs at the extremities. These larvae are in general very lazy, they do not spin threads or take up a posture of fear when disturbed. The second group concerns the superterrene (as a matter of fact generally concealed, either in the uppermost layers of the earth or under leaves etc., but not living typically in the earth) larvae. These are partly very brightly coloured and marked, they have no club-like processes on the bristles, very easily take up a posture of fear on being disturbed, easily spin threads and in general are very lively, forming a direct contrast to the larvae of the first group. Transitory forms of course occur. The pupae are generally coloured yellow to red-brown. Occasionally they are deep in the earth, occas¬ ionally nearer the surface, sometimes quite without and again with very tough cocoons. The number of cre¬ master spines varies considerably, as does the formation of the cremaster. 20. Genus: Euxoa Hb. This Genus is characterised by the stout spurs on the front tibiae (middle and hind tibiae also have spurs), by a bi-furcated clasper in the male sexual organ, having both prongs approximately of the same length and by a stout, crater or wart-like process on the clypeus. Now and then specimens occur in one and the same species without this projection. Type: E. decora Hb. Section I : Antennae of <§ pectinated to apex, pectinations long. E. rugifrons Mab. (= E. bledi Chret., E. urbana A. B.-H.) (Vol. 3, p. 24, pi. 5 c <$) (3 a). Algeria, Oran, rugifrons. Tunis. August to November. Early stages unknown. Section II: Antennae of pectinated almost to apex, pectinations long. E. subdistinguenda Corti (3 a $ type). A species that varies exceedingly both in colouration and mark- subdistin- ing. The types are very similar to the genuine distinguenda Led. but the antennae are more heavily pectin- guenda. atecl with wider pectinations. Orbicular stigma usually small, round with whitish centre. — v. mu hi sign a n. multisigna. (3 a d1 type) is to denote a grey to grey-brown form, orbicular and reniform stigmata almost extinct, no pale streak along costa and with distinct inner and outer transverse lines. It compares approximately as eruta Hb. does to tritici L. Perhaps this is a new species, related to the following mendeli Fdz. Spain, Albarracin in August- September. In spite of the extreme range of variation -of this fine species, a number of aberrations have already been named. — ab. diluta Scliaiv. with pale brown almost whitish brown forewings, markings diluta. extinct, pale costa, pale stigmata, black basal streak, black claviform stigma and the pre-marginal sagittate spots quite absent. — ab. obscura Schaw. is the name given to the counterpart in darkest brown with scarcely obscura. any markings. Albarracin, Spain. Ova whitish yellow, without ridges, in batches. Larvae almost uniform blue- grey, underside somewhat paler, lateral line and bands scarcely discernible. Head and scutellum dull buff, scutellum clumsy and divided. Larva similar to those of hastifera Donz. Pupa yellow-brown in a cocoon of earth, two diverging cremaster spines. 24 EUXOA. By Dr. A. Corti. mendeli. E. mendeli Fdz. (3 a <$ cotype). Similar to v. multisigna of the preceding species but much more vividly marked. Generally smaller, more unicoloured grey, no light streak along costa, inner and outer trans¬ verse lines as a rule distinct. Hindwings pure white to grey white. Specimens occur that are most distinctly deleta. marked and again others that are almost unicolourous. It varies therefore considerably. — The ab. deleta Fdz. with paler forewings and with extinct lines and stigmata is according to Boursin probably synonymous ■identata. with cos Hb., that is to say with a small specimen of this species. — - ab. identata Fdz. denotes specimens in the author’s collection without sagittate marks. Spain in September-October. Early stages unknown. capsensis. E. capsensis Ghret. (3 a). Similar to mendeli Fdz. but much more brightly marked and coloured, inner and outer transverse lines clear, a pale yellowish undulating subterminal line present.

Algeria in September-October. carthalina. E. (?) carfhalina Chr. (Vol. 3, p. 24) is probably no Euxoa but an Agrotis 0. (. Feltia Wkr.). The following species classified in Vol. 3 under Sections I and II, p. 24 — 26 do not belong to Euxoi but are to be classified under Agrotis O., (Feltia Wkr.): obesa B., scytha Alph., crassa Hb., dirempta Stgr., lasserrei Obth., boetica B., pierreti Bugn., matritensis Vasqu., fatidica Hb., sdbulosa Rbr., chretienni Dum., bifurca Stgr., segetum Schiff., robusta Ev . . characteristica Alph., trifurcula Stgr., tr if urea Ev., rata Ev., corticea Schiff., turatii Stdfs., anarmodia Stgr. and lanzarotensis Rbl.

Section III: Antennae of $ pectinated to 2/3rds of their length, pectinations shorter. E. temera Fib. In this species and its varieties I follow the researches of Boursin with the exception of villiersi Gn. despite the fact that everything is not clearly laid down yet and that all the variations are prob¬ ably simply colour and marking aberrations. The most likely is that temera-hubneri is a genuine varia- temera. tion. Underside of forewings in all forms with very distinct discoidal spot. — temera Hb. Fig. 393 (3 b) is considered by Boursin to be the type and this is the form with distinct inner and outer transverse lines, ruris. similarly coloured costa and almost absent claviform stigma. — v. run's Hbn. (3 b) has an indistinct clavi- form stigma, more faintly visible transverse lines, costal margin scarcely paler than ground colour. — v. (ab.) liubneri. hiibneri Brs. {= fictilis Hb. 710) (3 b type) has very distinct claviform stigma, paler costa and scarcely villiersi. indicated or absent transverse lines. — v .(ab.) villiersi Gn. (3 c) is the pale, sometimes almost unicoloured buff boursini. form with extinct claviform stigma, absent transverse lines and similarly coloured costa. - — v. boursini Schaw. $ dark brown to almost black-brown with reddish yellow, pale costal streak, $ dark vinous grey with pale costal streak and similar stigmata. A pale colour aberration from Corsica, which also occurs in Spain and the Apennines and probably everywhere else where temera occurs. All these forms do not belong to obelisca Hb. Mid and S. Europe, also according to Botjrsin, N. Africa, Asia Minor, Arndo. Breeding from the ova would perhaps produce clarity in regard to the above named forms, but only the early stages temera-hub¬ neri are known. Ova are deposited in batches, they are yellowish without ridges. Larvae when full fed are almost without markings, similar to hastifera Donz.

(3 c o type) is the north african race of hastifera. It is more brightly marked, the orange of the costa and the stigmata is much more vivid, the fore wings in comparison for instance with the austrian hastifera earbonis. are much more rufous instead of dark brown. Occurs also in Spain (Cuenca). — ab. (v.) carbonis Warr. (Vol. 3, p. 27, pi. 6 a) belongs here according to Kozhantschikov and not to obelisca Hb. These specimens originating from the Urals are said to represent the eastern subspecies of hastifera. The specimen illustrated in Vol. 3, pi. 6 a is a $ and the figure is too blackish, it should be more vinous. The has almost white hindwings. To the localities of distribution of hastifera in Vol. 3 we must add the Herzegowina. Ova very pale yellow, ridges faintly indicated. Larvae olive-grey with wide yellow-grey dorsal stripe; head and scutellum glossy. Pupa yellow-brown in a black earthern cocoon. bugeaudi. E. bugeaudi Obth. (3 c $ type). Generally smaller than obelisca Hb. but very similar otherwise to same. Can also be compared to hastifera-abdallah Obth. Varies considerably in colour and marking. Can be differ¬ entiated immediately from obelisca by the heavily pectinated antennae, from abdallah by the considerably less prominently pale yellow costal margin and also the orbicular and reniform stigmata. In abdallah the pale islyana. costal margin is always distinctly present, in bugeaudi much less and sometimes not all. — var. islyana Publ. 11. VII. 1931. EUXOA. By Dr. A.

Section IV : antennae of the $ with very heavy tuberculate or serrate fascicles of cilia. E. aquilina Schiff. (= fictilis Hbn. fig. 479) (3 g and Vol. 3, p. 32, pi. 6 k). Certainly a genuine species. The antennae differ considerably from those of tritici L. aquilina is generally much larger than tritici, paler and much more sharply marked. Stigmata stand out very prominently, hindwings of C paler, forewings cha¬ racterised by an occasionally very outstanding pale streak from claviform stigma obliquely downwards to¬ wards the outer transverse line and beyond same. Is often mistaken for distinguenda Led., although the £ of this species has quite differently shaped bipectinated antennae. It varies considerably. Germany, Switzer¬ land, Austria, Italy but probably still more widely distributed. Occurs in Asia Minor and Asia in a number of races that are difficult to distinguish.
