EDITOR'S PREFACE. \- 1 have already stated in my Preface to the 'Monograph of the I rylophidffl and Sphseriidae,' the entire collection- of Micro-Cok-optera In-longing to the late Rev. Andrew Matthhws passed into my possession at his decease> undi-r an arrangement, made Bhortly l)efore, that I should assist him in publication of the before-mentioned and present works, and in issuing this plement to the ' Trichopterygia Illustrata et Descripta,' I am pleased to have fulfilled my obligation to my much lamented friend. It is to be regretted that the Author did not live to revise these works as they were passing through the press, as I fear errors have escaped notice which he, no doubt, would have rectified. In preparing the manuscript of the present work for the press, I have only corrected any obvious errors that were detected, ehiefi}* in the references, otherwise the whole of the matter and system of arrangement is the Author'- own work. In the systematic and descriptive part of the work the Author has only included those species that he had an opportunity of examining himself, and for the most part contained in his own collection; others thai were only known to him by description will be found mentioned in the latter part of his Preface, with a translation of the original descriptions, or a short note of their leading characti rs. At the end of the Prefac 7), I have given a list, in chronological order, of some species that he had apparently overlooked, or had been described since be completed his manuscript. Mr. Matthews's collections, which now form part of my Museum, contain the types of all the Trichopterygia described by him, except twelve of tin Bpecies described in the present work, of which I have given a lisl at pagi LI, and i. colli ctions in which these may be found, for the information of anyone wishing to consult the types. Of the Plates, IX. to XIV. have been prepared for me from the original drawings made by Mr. Matthews with his well-known artistic skill and accuracy, the figures having been most carefully and satisfactorily transferred to zinc by Mr. J. Collin, of Newmarket, and I have to thank him for the trouble and pains he has taken to make them accurate copies of the originals. Plate XV. is a photo-lithographic reproduction of that published in Mr. Mattiikws's 'Essay on Hydroscapha,' and has been carefully prepared for me by Messrs. West, Newman, and Co., in order to complete the illustration of all the new genera discovered since the publication of the ' Trichopterygia Illustrata et Descripta ' in 1872. The Plates have unfortunately been numbered IX. to XV. consecutively, in continuation of those in the ' Monograph of the Corylophidse and Sphseriidse,' as it was at first intended to issue the two works as one volume. I must also express my thanks which are due to Mr. G. C. Champion, Mr. C. 0. Waterhouse, and Mr. George Lewis, for the assistance they have given me, and more especially to Mr. 0. E. Janson, who has been of invaluable service to me in verifying and obtaining references to the literature, reading proofs, preparing the Index, and other matters in connection with the printing and publication. PHILIP B. MASON. Burton-on-Tren] July, 1900. 1MJ EFACE. Thk publication of the ' Trichopterygia ttlustrata' in 1872 aroused among entomologists an interest in that previously neglected family which has proved so fertile in its results, that about one hundred fresh species, including seven new genera, have already been brought to light. In the preface to that work I expressed my belief that the Trichbptt rygida would eventually prove to be one of the most numerous families of Coleoptera, and subsequent events appear to have fully justified my anticipations. The collections sent from every recently explored part of the world contain on an average three-fourths of species new to science, and these in most cases exhibit very obvious distinctive characters. The genus Trichopteryx forms the principal if not the only exception, for its multitudinous '•ies often so closely resemble each other that, without the aid of a powerful microscope, or the presence of types of allied species for comparison, it is difficult to perceive in what way they differ from those already known. In the same preface I also endeavoured to explain my views on the altinities and systematic position of the Trickcpterygida, and a prolonged study of those insects, together with a more perfect knowledge of their anatomy, has tended to confirm my views with regard to their affinities, but slightly to modify them in respect of their systematic position. At that time, perceiving their close alliance to the Staphylinida, I proposed that in a systematic arrangement the Trickoptery- gida should be placed immediately before the Staphylinida ; but 1 am now inclined to think that that arrangement should be transposed, and that, instead of preceding the Staphylinida, the Trichopterygidai should follow next in succession to that extensive group ; by this change their alliance would lie maintained, while the transition into other Clavicorn families would be more naturally accomplished. The chief cause which has inclined me to maki this alteration consists in the formation of their anterior coxa?. In all the groups which have by general consent been hitherto placed before the Staphylinida, and in most genera of Staphylinida themselves, these limbs are long and free, or, as they are sometimes termed, prominent — i.e., unconfined by any coxal cavity ; but throughout th( TrichopU rygida the anterior coxne are placed in a cavity of the prosternum, which with very few exceptions is perfectly closed on both sides. This is an important anatomical character, and strongly indicative of affinity among groups in e\< re- section of the whole Order. B Within the last few years the importance of the skeleton of the under side in tnatic arrangrim nt lias been brought into a prominent position, chiefly through the exertions of Dr. Le Coiite and Dr. Horn. And, working upon their lines with the aid of more powerful instruments, I have discovered some few points in the skeleton of the Trichopterygida which I had previously overlooked. The most noticeable of these exists in the size and form of their mesosti rnal epimera. In the Trichcpterygida this portion of the skeleton is unusually large, and extends from the outer margin of the body to the intermediate coxal cavity, inclosing the whole of its outer side. This enlargement of the mesosterual epimera prevails with very little variation through all the genera of the family, and is in truth one of its most distinctive characters. It is clearly shown in the plates of the new genera — any one of these may be regarded as a fair type of its older allies. The part which I had supposed to be this epimeron, and which in size and shape closely resembles that part of the skeleton in all other Clavicorn families, proves to be in. inflexed apical angle of the episternum of the metasternum. The figure of the under side of Nanosella fungi in PI. xiii. A, is an apt illustration of all that I have endeavoured to explain in the foregoing sentences. I have placed Limulodes at the commencement of the Trichopterygida on account of the similarity of its outline to Hydroscapha, and have also separated it from the other genera as a distinct tribe, which may be characterized thus : •' II. ad, pronotum, and elytra together forming a compact cone, furnished at its apex with long setae." I have also good reason to believe that other species belonging to this Tribe will eventually be discovered. I must here add a few remarks on an important essay on this Family by Dr. C. Flaeh, of Vienna, published in the ' Verhandlungen der Kaiserlich-konig- licheu zoologisch-botanischen Gesellschaft in Wien," xxxix. 1889, pp. 481-532.* I am sorry that I cannot do this in a more satisfactory manner than by merely transcribing, or rather translating to the best of my ability, Dr. Flach's original descriptions. Some few, of which I have received types from Herr Reitter, will be found described by myself in the course of this work, and, so far as I can judge by those and by Dr. Flach's own characteristic figures of some others, I believe that most of his species will prove to be genuine : — Ptenidium ovulum. — Thorax widest at the base ; body egg-shaped ; basal fovese wanting; thorax with the elytra arched in one curve. Beetle of a fine chestnut brown, thorax finely margined ; body large, upper side impunctate, transverse line on the scutellum without medial impressions. Hab. near the Caspian Sea. Ptenidium Lederi. — Thorax with the basal and anterior fovea' small, but distinct ; body oblong, pitchy black ; thorax marked with a transverse depression at the base, surface very finely reticulate, very finely and sparingly punctured, thickly clothed with short hair; transverse line of the scutellum with a fovea on each side near the angles.

Zeit. vii. 1888, p. 103, Dr. Flach described the following species of / i ichoptt i i/.r : — Trichopteryx rufilabris. — T. lata, Mot -eh. exacte fere statura, lata, fere quadrata, oapite thoraa qui nigropiceis, elytris atrorubentibus. margine extrema, labro superiore, ore, antennis unicoloribus, pedibusque bete rufi oentibus; thorace toto et omni superficie transversim retieulatis, tuberculis modicis, ordinibus plus minusve arcuatis, transversis, baud dense obtectis, et minus dense fulvo-pilosis ; caput oculis minoribus, ocellis c.c.a. 20 visibihbus ; ctetera omnia T. lata similia ; thorace paulo ante angnlos posticos latissimo ; elytris latiore, flavo-marginato ; elytris latitudini aquilongis; corp. long. 0-92, lat. 0-5(3 mm. Patria. Talysch, Lenkoran. — Leder com. Reitter. This species might be taken for /'. lata, but can easily be distinguished by the con- spicuous reddish yellow colour of its mouth, pale yellow antennae, more shining surface, pecially by the eyes, which are only hall' as large, and by the dark red colour of the elytra. In the same paper (pp. 101, 102 1, this author described at length the following four species : — 1 'til i urn Sahlbergi. >'. Hopffgartmi. ,, Led>-ii. ,, Oertzi ni. But these have been already noticed in this Preface. In the Dents. Ent. Zeit. xxx. ]8S(i, p. 248, Dr. Flach described at length Ptilium CEdipus .' but I found, from types kindly sent by Heir Reitter, that this species is identical with one described by myself in the Ann. and Mag. Nat. Hist. 1889, p. 195, under the name of I'lilium <,l,c,i cation. Dr. Flach's mime must therefore be used in future for this species. L'Echange, Revuo Linncenne (Lyon), No. 50, Feb. 1889, p. 4. In this periodical Mr. Key very briefly notices many Trichopterygida, which he considers to be new species, but it is not possible to form any opinion of their validity from the short remarks appended to their names. All that I can do is to transcribe his remarks, and to leavt the identification of the species to those who may have an oppor- tunity of examining the original types. Ptenidium obsoletum.

Crotcb first discovered tbis extraordinary genus in Spain, and in 1878 he was fortunate enougb to meet with it again in California. Tbe American insect proved to belong to a species distinct from its European congener, and was described by Dr. Le Conte in 187-1 under tbe name of Hydroscapha nutans. Tbe European species, Hydroscapha Crotchii, was shortly after described by Dr. Sharp in tbe Em. Monthly Magazine. Specimens of both species were subsequently sent to me for dissection, and the result of my investigation convinced me that tbe genus was closely allied to the Trichopterygida. To the opinion which I then expressed as to the affinity of Hydroscapha to the Tricho- pterygidte I still in the main adhere, but, on account of the unilobed maxilla? of Hydroscapha, consider that it should be regarded as forming a distinct family. I do not at all agree with the idea, lately brought forward, that the specific name Gyrinoides, Aube, can be properly applied to II. Crotchii. With Limnebius, 15 Hydroscapha has no anatomical connection, and it would seem almost impossible that bo accurate and experienced an entou is Dr. Aube could have overlooked tin- conspicuous maxillary palpi of the insect lie was then describing; and, in ration of this conjecture, 1 have received from Dr. Sharp types of Limnebius Gyrinoides, taken at the .-aim- place and in company with h ipha, which their trui characters beyond the p of a doubt. In dried specimens, when the long abdomen of /. contracted, the resemblance between L. Gyrinoides and // I is so i lose that they might easily be mistaken for each other; but the most casual glance at the palpi and antennae is at once sufficient to distinguish them. And, again, if the term inoides be a ~ - i u' i : > 'I to //. Crotchii, by what name can the /.- be known? On every account, th< . it seems expedient to retain the uame Crotchii for the species described by I>r. Sharp. The elongate form and tin number of the corneous segments of the ahdomen in Hydroscapha indicate an affinity to the Staphylinida, and thus that genus presents a connecting link between the Staphylinida and the Trichopterygida, and such appears to be its proper place in any systematic arrangement.

Sonn entomologists have lately asserted thai in Ptinella both sexes may possess wings; I cannol of course contradict this assertion without examination of the pposed winged males, but, until convinced to the contrary by ocular demon- stration, I shall Btill adhere to my previously expressed opinion — thai ible wings are confined to the t'< males alone. Indeed, the law of what is called Nature strongly supports this id< a, for, as it is well known in the history of \nt - and their allies, the power of lli.^ht in the females is the main factor in the preservation and diffusion of the species. I have for many ojoyed unusual facilities for investigating the habits and anatomy of insects genus; more than two thousand specimens ha\' under my examination, and I have always found that the presence or absence of wings formed an unmistakable indication of the sex of the individual. I mean by "wings" not mere rudimentary apologies for those members, but fully developed serviceable wings, and 1 have many anatomical preparations which (dearly prove that winged specimens are always females : in some of these the ova are Been fully formed, and ready for extrusion. 1 may go i farther than thiB, and say that in specimens in which the wings, although presi nt, are more or less imperfect. trium is in a similar condition, hut in ry such case male organs are wholly absent. I am fully aware that in some undoubted males minute appendages may be discovered arising from that part of the mesothorax on which the wings articulate, bul these can by no stretch of imagination he regarded as wh Many Luten 3ting species have recently been added to this genus, and one I ago recorded by Col.

Like Homalota among the Staphylinida, Trichopteryx contains a vast numl of specie.-, which to the naked ey< . i spi cially of an inexperienci d obsi rver, pn no obvious difference ; although wheu examined under a powerful mici they are found to differ from each other abundantly in outlu en< rally in both these characters. Some may possibly he climatic or local forms, hut 1 believe the vasl majority are true .-pecies of science at lea8t, if not of nature. I say "of science," because wherever any reasonable doubl better to - . than Injudiciously to amalgamati divei I also that the form which may bi led a- the original type is ofl 1 in the same region and under similar conditione ural climatic or 1 variety, is Btrong evidence that tb< taUy distinct, and not th< 88 spring of evolutionary progress. Thus, for instance, the species which I have called T. minor, found by Mr. Champion in Guatemala, bears bo strong a resemblance to the European T. grandicollis that it might be considered a local form of that Bpecies, the difference between tbem consisting in the much smaller size of T. miliar, and in the Bhape and sculpture of its thorax; if, however, climatic or other influences had in this case led to metamorphosis, their effect would have produced similar results through the whole rait-: but, in contradiction to such a theory, 'J', grandicollis, agreeing in every respect with the European type, was also taken by Mr. Champion in the same region as '/'. minor; to separate the two, therefore, seems the only way to avoid confusion. Instances of a similar land have also occurred with other Bpecies of Trichopteryx, and notably in the case of '/'. atomaria, of which the original type form is found in almost every region together with allied species. The species of Trichopteryx are probably more numerous than those of any other genus of Coleoptera, and owing to their minute size the difficulty of distin- guishing them from each other is so great, that an incipient student feels often inclined to give them up in despair. And, since it is sometimes impossible to arrive at a satisfactory determination without actual comparison, collectors should always hear this fact in mind — they should collect plentifully whenever an opportunity occurs, and distribute authentic types with the utmost liberality. Owing to the multitude of species now contained in this genus, no synoptic tabulation would prove of any use. I have, therefore, in the following pages, given a separate and full list of every species which has hitherto been found in each principal division of the world ; and have added to every species a few of its leading diagnostic characters.

Found by Mr. Crotch in Cambridgeshire, aud by Mr. Morris near Lewes, in Sussex. This insect appears to he the true Ptilium affine of Erichson ; it agrees in size, colour, and sculpture with his description in the " Ins. Deutsch." I had formerly received \\ pes from two contim ntal sources labelled " P. affine," which were identical with the insect I found in Wicken Pen, and described as P. affim in my former work, the ' Trichopterygia LUustrata.' I have now separated this species under the name P. incognitum. It is much larger than the /'. affine of Dr. Erichson, nearly black, much more convex, and very diverse in sculpture. The discrepancy of size and form existing bei ween my own specimen and those subsequently taken in this country first drew my attention to the subject, and con- vinced me that they could not belong to the 9ame species. The change of nomenclature does not, however, affect any but my own speci- men; all the other Ptilia with parallel lines on the thorax which I have hitherto seen belong to Ptilium affine, Erichs.

D from other species in its large size, dark colour, very convex elytra narrowed at the shoulders, and peculiar sculpture.

Habitat, Europe. Found in England by myself in Wicken Fen, Cambridgeshire ; also in Holland by M. Xeervoort van de Poll. Thi- fine -pecies is one of the largi st of the present genus, and very distinct in appearance. It seems to lie very rare, since among all the continental collections which 1 have examined it is represi uted only in those of M. Reiche and M. Xeervoort van de poll, and in both was labelled " Pt. affine ; " under that name, therefore, I described the species in the ' Trichopterygia Dlustrata.' Since then several specimen- of the true P. affineoi Erichson have been taken in various part.- of this country by Mr. d. II. Crotch, and Mr. Morris of Lewes; the occurrence of these smaller, paler, and more pubescent insects induced me to compare them carefully with Erichson's description, with which I found that they entirely agreed. It consequently became necessary to distinguish our present species by another name, as I now have done. Ptilium planum. P. planum, Matthi ws, Trans. Am. I'.nt. Soc. \i. p. 1 1 I, Is--! ; Biol.

The above is an analysis of Mr. Casey's elaborate description in bis ' Es i on Now Genera and Species of California!! Coleoptera.' .1. attenuatum seems to be a distinct species, allied to A. granuhmm and .1. rotundicolie, from both of which it apparently differs in its more narrow and elongate form, more dense pubescence, and finer sculpture. II is at present represented by a single individual found by Mr. Casey in California. Gen. XX.— PTENIDIUM. Fifteen fresh species have been added to this genus. Of these, P. Lawsoni and /'. Ulkei belong to the variolose group of which P.punctatum is the type ; twelve are more or less allied to V. evanescens; and one, P. strangulatum, is of such an ex- ceedingly abnormal character that, if 1 did not strongly object to subdividing on insufficient grounds, I should feel inclined to form a separate genus for its reception.

Motschulsky from examples round in India, and figured by him in the same work (Tab. viii. fig. 1). His • I. scription, like all his other descriptions, is very unsatisfactory, but, ae far as it goes, agrees with the insect found in Japan by Mr. Lewis; his figure is much more iressive, and has convinced me that Mr. Lewis's insect is identical with Campto- diwm adustipenne.

N. fungi, the only species contained in this genus, has been so often accurately described, and is so clearly represented in PL XIII. A of this work, that it is need- less to say more than that it is bright yellow in colour and clothed with a short golden pubescenee. Among the Trichopterygidee collected in Central America by Mr. Champion, I was very much pleased to find an example of this most minute of all the Coleoptera, more especially as it enabled me to complete my previously imperfect description by adding an account of its antenna. In Dr. Le Co specimen these limbs had been broken off, but in Mr. Champion's the whole head had become detached from the thorax in the process of mounting the insect on card, and thus the antennae could be examined without any trouble.

North America. A single specimen found in the United States by Mr. G. E. Crotch : the precise locality not mentioned. The single example of this very distinct species was sent to me by my friend, Mr. Crotch, shortly before his death, but did not arrive until that lamented event : .ken place. His premature death proved to science a serious loss, and to his friends a perpetual zr'ef ; and to his cherished memory I now dedicate this second part of a work, to the former part of which he so largely contributed.
