Tue state of society in which the works of Creation are duly investigated, is not its state of infancy or boyhood, but that of its maturity and confirmed manhood; for, in its earlier and ruder stages, the sciences in general are looked upon with indifference, and not seldom with contempt; but, in proportion as civilization advances, they acquire daily more and more importance. ‘The last, probably, that is raised to its proper rank in the public estimation, is the study which is distin- guished by the name of Natural History: hence it happens that the patronage and fostering care of princes and statesmen have been usually extended later to this branch of science than to any other; and a just sense of the value of it, in public men, seems an indication of a very advanced state of society, and a proof that the public mind is wholly liberated from all the trammels of prejudice. When the inspired wisdom of the most powerful and magnificent of the Hebrew monarchs was directed to this object, and he composed treatises, for the instruction of his people, both upon plants and animals, then the Israelitish nation had attained the acmé of its civilization and glory; and that celebrated Greeco-Macedonian prince and conqueror, whose highest privilege it was to have been the pupil of Aristotle, at the period when science in Greece had attained its zenith, is related to have given it in charge to his tutor to pay particular attention to the study of animals, and, in order to furnish him with materials, employed several thousand men, both in Europe and Asia,! in collecting them. But it is seldom that sovereigns, or their ministers, have extended their fostering patronage to the science in question, till their attention has been excited by the 1 Plin. Hist. Nat. 1, viii, c, 16. xX INTRODUCTION. celebrity, studies, and labours of some eminent individual amongst their subjects ; and they have thus been induced to cast an eye of favour upon them; their own thoughts and time are necessarily too much absorbed by politics, and the higher duties of their station, or office, to allow them much leisure to direct and em- ploy them elsewhere, unless some such stimulus awakens their attention to the subject, its merits, and claims to notice. It was by his ardent zeal in the cause he had embraced; and the mighty power of his intellect; and his indefatigable labours and studies; and his profound knowledge of his subject for the time; and the wide celebrity of his name, that the Aristotle of the North, the illustrious Linné, attracted to himself, and the science that he loved, the favourable regards, and the effectual aid of the higher powers ; in consequence of which, under their auspices, eminent naturalists were sent out to explore various and distant regions, for the purpose of discovering, studying in their native soil, and collecting, their natural productions. Thus it was that Kalm went out to North America; Tornstroem and Osbeck to China; Forskahl to Arabia; Thunberg to Japan; Sparrman to China and the Cape; Hasselquist to the Levant, Palestine, and Egypt ; and others to various other regions of the globe. In our own country, till within a few years, the collection of natural productions made no part of the official duty of those employed by government in exploring unknown, or little known, countries ; and if such collection was made in any expe- dition undertaken by authority, it was solely owing to the taste and inclination of some individual connected with it. It was thus that the late Rt. Hon. Sir Joseph Banks, led by the love of science alone, and his own native ardour in her cause, at first distinguished himself; a circumstance that became the stepping-stone which originally placed him upon the eminence in the scientific world which from that time he held, and which caused him, in the event, to be looked up to by those in power, and enrolled him in the list of his Majesty's Most Honorable Privy Councillors. Accompanying Capt. Cook, the most illustrious of our circumnavi- gators, in his first voyage, with the aid of his zealous and learned friend the late INTRODUCTION. XXI Dr. Solander, he made such collections, both in Zoology and Botany, as had never before rewarded the zeal and efforts of any single individual; and from regions which till then had remained unexplored, and of some of which the very existence was till then unknown, poured vast sums of her peculiar wealth into the general treasury of Natural Science. Sir Joseph employed the influence he had acquired with the Government in ’ promoting the interests of that science, and securing to it a portion of the same en- couragement which had been bestowed upon other branches of art and literature ; so that to examine and collect the natural productions of a country, began, at length, to be regarded as an important object, and to form part of the official duty contained in the instructions delivered to commanders of voyages and expeditions of discovery. And, certainly, merely to ascertain the geographical position and limits of any country, considered as the sole object of such expeditions, although to the Geo- grapher and Navigator confessedly of the first importance, yet considered per se, and independently of any knowledge of the inhabitants and productions of such country, it loses the largest portion of its interest. The advantages that may be derived from an intercourse with it, furnish one of the principal motives for ex- ploring it, and these may be ranged under two heads, accessions to science, and accessions to commerce: the former as useful in the enlargement of the human mind, in the improvement of the human intellect, and in adding to our stores of knowledge ; as the latter is in the enlargement of our property, and in adding to our stores of individual and national wealth. And the studies, Jabours, and obser- vations of the man of science often lead to knowledge highly useful in ascertaining how far the latter object may be promoted by intercourse with any given country. The Zoologist, the Botanist, and the Geologist, each in his peculiar department, may direct the attention of the man of commerce to those districts where such productions of the animal, vegetable, or mineral kingdoms abound, as may be made articles of profitable speculation. d XXil INTRODUCTION. Amongst the other objects of Natural History collected in Captain, now Sir John, Franklin’s last Expedition to the Polar Seas, the Insects form a very prin- cipal and interesting feature, not only on account of the number of individual species, which is considerable, but also on account of several new forms which they present to the scientific Entomologist; some of them connecting tribes before placed far asunder,? and filling up many vacant places in a scientific arrangement of these minute but not unimportant animals; others exhibiting an Asiatic aspect ;3 and the majority representing, as it were, known European types; and though vary- ing from them in characters of more or less importance, known European species; so that the American Entomologists, for want of comparing one with the other, appear often to have confounded them. Dr. Richardson, who was associated with Sir John Franklin in his first, as well as in his second, Journey, and to whom was intrusted the Natural History Depart- ment of the Expedition, the duties of which office he fulfilled with the same inde- fatigable zeal and singular skill, that his excellent commander evinced in the general conduct of it, having, at the recommendation of my worthy and learned friend, the Regius Professor of Botany at Glasgow, Sir W, J. Hooker, placed in my hands the above collection for arrangement and description, I must here premise a few obser- vations on the plan I intend to pursue for the accomplishment of those objects. I must first observe that the majority of the insects in question were necessarily collected during the brief summers of the Arctic regions, when it was requisite to use all possible dispatch in proceeding northwards while the season permitted : it was to be expected, therefore, that they must be hastily put together in boxes, or bottles of spirits, as they were collected, but it is wonderful, considering their number, that so little damage was sustained from this mode of packing them, none having received such injury as to render it difficult to describe them, except some of the Diptera, and the Libellulina, of which there seem to have been many, and which were so mutilated, most having lost their abdomen, that they could not be ascertained or described. 2 For instance Opisthius Richardsoni, Plate I, Fig. 9. 3 Carabus Vietinghovii, Plate I, Fig. 3. INTRODUCTION. XXIll Having in my cabinet a number of insects, including some new and singular forms, which were chiefly collected in Canada by Dr. Bigsby, and in Nova Scotia by Dr. Mac Culloch, I thought it would add considerably to the interest of the present Fauna, if, as far as relates to the insects, it were made coextensive with the British Territories in North America; I have, therefore, with the consent of Dr. Richardson, included them in my catalogue, which may thus be regarded as the first attempt at an outline, meager indeed and imperfect, of British American Entomology. I must also here observe, that several of the insects collected in the Expedition, were taken in the journey from New York to Cumberland-house, without its being noted on which side of the 49th parallel of Latitude, the southern limit of the Zoology of the British American Fur Countries, as fixed in Dr. Richardson’s Introduction,* they were taken; so that it was not in my power to distinguish the species taken in the British from those taken in the American territory. I thought it therefore best to include the whole. So many different methods of arrangement have been traced out, or adopted, by different Entomologists, no two having altogether pursued the same path, that when I first set to work upon these insects, after I had ascertained the genus to which each species belonged, and which of them appeared to be non-descript, it was a source to me of no little thought, doubt, and perplexity to determine upon whose footsteps I should tread in the arrangement of them in a series, especially with regard to the Coleoptera Order, or Beetles. ‘Two eminent Entomologists, my lamented friend M. Latreille, and Mr. W.S. Mac Leay, amongst others of less note, have taken great pains to form natural groups, but upon different principles, and both have rendered important services to the science ; but both also, in some degree, by the adoption of an hypothesis, have tied their hands and impeded their own progress. M.

Mr. Mac Leay, likewise, by assuming the number fie for the universal regulator of every group—whether primary, intermediate, or ultimate—of the whole animal kingdom, though in many cases it may prevail, has by no means made it clear that it is the keystone of the mighty arch of nature, or the clue by which her mazy labyrinth may be traced through ad/ its windings and recesses. Whoever considers the infinite ramifications of the Animal and Vegetable King- doms, the vast number of groups differing in rank and value, and rolling wheel within wheel, almost ad infinitum, of which each consists; may readily conceive that the formation of a numerical system, whether the number assumed as the regulator be two, three, four, five, or seven, is a labour of no very difficult accom- plishment; but to construct it so that the groups of each section, from the primary to the ultimate, shall be equal or nearly equal in value, which alone can prove that it is the system of the Creator,—hic labor, hoc opus est. Mr. Stephens, in his Systematical Catalogue of British Insects, containing, I believe, the last that has been published, has given a still different, and, upon the whole, an improved arrangement, in which he implicitly follows neither of his predecessors, and has taken great pains, as far as his means and limited subject permitted, though in some things he also appears to me mistaken, and who is not? to follow the light afforded him by nature. Sir J. F. W. Herschel’s observations on this subject merit particular attention. “The classifications by which science is advanced, however, are widely different from those which serve as bases for arti- ficial systems of nomenclature. ‘They cross and intersect one another, as it were, in every possible way, and have for their very aim to interweave all the objects of nature in a close and compact web of mutual relations and dependence.” 5 Disc. on the Study of Nat. Philosophy, Cab. Cycl. xiv, n. 134. INTRODUCTION. XXV When so manv eminent men form different conclusions from the same premises, we may rest assured that there is something in the subject of their lucubrations that admits of hesitation, and justifies variety of opinions; and this is clearly the case with respect to the arrangement of natural objects; for whether we consider the productions of our globe, in all their affinities, as best represented by a branch- ing tree, a net, or a sphere formed of an infinity of larger and smaller orbits, connected on every side, and placed ad infinitum wheel within wheel; if we set ourselves to arrange and describe upon paper the individuals composing any de- partment of the three kingdoms, we shall find that it is above us either to conceive or delineate it so as to maintain all its connections undisturbed and unbroken. We must do it in a series, which can only be a series of mutilations and disloca- tions. It will be like cutting off every branch and twig of the tree to place them end to end; like tearing up the net to place all the meshes one after the other; like blowing up the whole sphere, and unravelling, as it were, all its orbits great and small, to make a continuous thread of them. So that it is a hopeless case to attempt an arrangement according with nature in all its parts; vain man, with all his boasted powers of intellect, cannot conceive, much less utter and embody it. All that he can accomplish is to give some general idea of it, and to describe some fractions of it. He can also attend to the composition of his groups, and keep those together that are really related; but as to conterminous groups, he will often be at a loss which is nearest to the one in question, for from different parts of the same group, a variety of others will often branch off in different directions. In the following pages, therefore, profiting by the labours of my predecessors, I have sometimes followed one and sometimes another, according as they appeared to ine best to have interpreted nature, and sometimes, where it seemed expedient, I have entered new paths in my arrangement; it has been my endeavour principally to make my groups as near to nature as possible, but with regard to the series and concatenations of them, for the reasons above assigned, it was not possible to place them on paper as they are inscribed, by the Great AuTuor of nature in her pages. XXVI INTRODUCTION. The author cannot conclude this Introduction without returning his acknow- ledgments to those gentlemen, to whom it will appear from a perusal of the fol- lowing pages he is under great obligations for very considerable additions to his catalogue of the insects of the British Provinces in North America, namely to Dr. Bigsby, of Newark, and Capt. Sheppard, of her Majesty's Royal Regiment of Artillery, for those of Canada; and to Dr. Mac Culloch, and Capt. Hall, late of her Majesty’s 81st Regiment, for those of Nova Scotia. From Dr. ‘Thaddeus Harris, and Mr. Drake, he has received several specimens from the Province of Massachusets, which are likewise found in the British Provinces. INTRODUCTION. XXVIl The following Tabie exhibits the groups adopted in this work in the Orders Coleoptera and Hyme- noptera only, the author, on account of the small number of specimens collected, having made no additions to those already established in the other Orders. te III.

But though Entomologists have paid some attention to this circumstance, they appear to have gone little further, and have not made all the use that they might have done, with advantage to the science, of the sexual dis- tinctions observable in this part of these animals; for they have taken little or no notice of the variations in the clothing of the sole or underside of these dilated joints; speaking of it generally, except in the case of male Dytiscida, merely as a brush. Liatreille, indeed, in his last work,? mentions papillae as well as brushes, 1 Lat. Cours D’Ent. i, 18. These are the Annulosa of modern Zoologists. For my reasons for adopting Latreille’s term in preference, see my Bridgewater Treatise, ii, 17. ? Ihave not adopted, on the present occasion, the phraseology proposed in the Introduction to Entomology, (vol iv, p- 393) to distinguish the different subdivisions into which each section of an Order is resolvable, in descending to the families and genera, because I have not the means of applying it universally, or of making such a valuation of each as will indicate at once the denomination to which it is entitled. > I consider the Euptera as forming three subtribes—viz. Longicollia (Colliuris,) Brevicollia ( Cicindela) and Fissicollia ( Manticora. ) 4 Carnivora, Lat. > Crust. Arachn et Ins. i, 401. 2 NORTHERN ZOOLOGY. but seems not to have examined them very closely, and to have acquired no very precise idea of their nature. I shall, ‘therefore, under the present head, enlarge a little upon this subject. ) The Predaceous Beetles, considered with respect to this circumstance, are of three descriptions. 1. Those that exhibit no such distinction. 2. Those that have only the anterior tarsi or hands dilated. 3. ‘Those that have the two anterior pair so circumstanced. | . 1. This sexual character, though very general, is not universal in the 4dephaga. In the Cicindelidans the dilatation, though existing, is less conspicuous; in the Colliuridans the tarsi in both sexes are dilated, so that in them it is no sexual distinction ; and the same circumstance occurs in the Longicollia—Agra, Casnonia, &c. amongst Latreille’s Truncatipennes (Brachinide Mac Leay); in the Manti- coridans, and the Bipartiti Latr. (Scaritide Mac Leay) and likewise in some of the Truncatipennes, as Lebia, Dromia, and in some Carabidans, as Procerus, there is no dilatation in either sex; and amongst the Hydradephaga Mac Leay, the sexes of Haliplus seem very slightly distinguished in this respect. 2. The majority of the Geadephaga have only the anterior tarsus or hand of the male dilated, and may be distinguished, with regard to this circumstance, by the name of Dimani; some of the Truncatipennes have only the posterior side of the joints dilated, this is the case with Anthia, Galerita, &c. but, more' gene- rally, both sides of the three or four first joints are so circumstanced; in the Hydradephaga, only in Hydaticus and Acilius, this character is restricted to the hand. 3. Amongst the Geadephaga, Latreille’s Quadrimanti—Harpalus, Ophonus, Ste- nolophus, &c.—have the joints of the four anterior tarsi dilated, but amongst the Hydradephaga this character is to be found in the majority. The next circumstance, that calls for our attention, is the number of these dilated joints, for they vary in different tribes and genera. Thus the Peryphid@ have the first joint only of the hand dilated; the Bembidiade the first and the posterior side of the second; Patrobus, Pogonus, &c. the two first; but the most common, or what may be called the ¢ypical structure in this respect, is that in which the three first joints are dilated; this obtains in the Cicindelide, Calosoma, and the great majority of the Eutrecha, even in those that have the four anterior tarsi dilated; in the Hydradephaga the same number prevails ; in the Carabidans and Trechus, &c. four joints are dilated. The most important circumstance, however, connected with the present subject ’ DSI ADEPHAGA. 3 is the lining that covers the sole of these dilated tarsi, or the kind of foot-cushions with which they are furnished. ‘These are of three descriptions. 1. A dense brush of stiff hairs. This is to be found in the Cicindelidans, the Carabidans, and the Chleniadans; insects so furnished may be denominated Sarrothropoda. I have noticed no particular variations of this kind of foot- cushion; in the last mentioned tribe, however, the Chleniadans, the brushes are broader, the consequence of the greater dilatation of the joints, than in the other Sarrothropodous Geadephaga. 2. The next kind of foot-cushions are formed of little membranous vesicles or cysts, which are arranged in various ways in different tribes. In some, as Helluo costatus, the hand is furnished with a compound cushion, there being a brush on each side, and in the middle a line formed of short transverse rows of vesicles; in Anthia the dilated side of the joint only has a line of vesicles included between lateral brushes; in Brachinus and many others is a double oblique series of vesicles on each joint; in Agonum these vesicles are imbricated lying one upon another ; in some, as in Harpalus interpunctatus of this catalogue, these little organs are arranged without order, and cover the whole joint. In this respect this species differs from the other Harpali, in which the vesicles are arranged nearly as in Brachinus. The insects that have this kind of foot-cushion may from it be named Cystopoda. 3. The third description of foot-cushions is when they are formed of peduncu- lated cups or suckers, as in several of the Ffydradephaga, particularly Dytiscus, in whose hands may be seen two larger umbilicated cups with an infinity of minute ones, which I have elsewhere described.6 These may be named Pyzidiopoda. The great object of all these formations is to enable the male to fix himself firmly in coitu, which is probably done by producing a vacuum, for which at least the cysts and cups seem particularly fitted,’ and they may be rendered useful in tracing the affinities of the different groups of the Section, as will appear under another head. GeapePpHaGa. Numerous, and seemingly inextricable, difficulties stand in the way of a perfectly natural arrangement of this vast group, which includes the whole of the Terrestrial Predaceous Beetles, for the Systematic Entomologist feels quite at a loss, when he asks himself by which path shall I next proceed? Though 6 Introd. to Ent. iii, 693. 7 Ibid, 691. 4 NORTHERN ZOOLOGY. its typical Tribe, the Euptera offer no very material obstacle to the accomplish- ment of his purpose, a number of rival forms next present themselves, each preferring seemingly well founded claims to guide him towards a natural arrange- ment. Under the present head, perhaps, it may be useful to discuss this subject, a clear insight into which will prove, that it is not at all wonderful that Entomo- logists have adopted different methods of arrangement, and that each, is in some degree right. It may first be asked—what is that Typical Form, from which, led by nature, in an attempt to arrange the insects of the present Order, we must set off, as from a common centre or summit, round which all, as it were, revolve, and towards which all tend? This is a question, even in the present advanced state of the science, difficult to answer; for we have beetles before us of vast bulk and strength, elephants in the class of insects, but which are distinguished neither by the swiftness of their motion nor by the elegance and beauty of their forms; others we have, less clumsy indeed and gigantic, but remarkable for the perfection and symmetry of their general structure; the lightness and velocity of their motions both on the earth and in the air; and for the splendour and brilliance of their colours. Such, with only one or two exceptions, are the Euptera or Tiger Beetles. Amongst the higher animals, the Lion, chief of the Predaceous Quadrupeds, is usually accounted as the king of beasts; a similar reason will justify modern Entomologists for regarding the above tribe of beetles as the typical and most perfect form amongst insects, especially Coleoptera, instead of the Lamellicorn beetles, which Linné had elevated to that rank. Having selected a typical or central tribe, let us next consider its composition. As far as at present known, it is composed of three principal groups. One remark- able for its long cylindrical neck and slender body, and for having all the tarsi of both sexes dilated and furnished with a brush, the penultimate joint terminating in a single lobe, the type of which is Colliuris longicollis ; another with a short depressed neck, a stouter body, slender tarsi, with only the three first joints of the hand of the males slightly dilated, and covered underneath with a brush, and the penultimate joint not lobed, the type of which is Cicindela campestris; a third, removed to a vast distance from the preceding ones both in its aspect and many of its characters: in the former and its colour, which is a dismal black, resembling Latreilles Melasomes ; as to the latter, though the claw of its maxillz articulates with the lobe, and the mandibles are armed by long and threatening teeth as in Cicindela, yet having a neck or prothorax, like that which distinguishes the males in Anthia, bilobed behind; having the surface of the elytra plane with a 0g ADEPHAGA. 5 very large Epipleura; having no wings, and the hand of the male not being dilated nor furnished with a brush. The type of this sombre tribe is Manticora Gigas. From this statement it appears that in this ‘Tribe, as at present known, there is no circular arrangement, it may be rather said to form a semicircle, beginning with the Colliuridans, passing from them by the narrow Cicindelidans to the type, and thence proceeding by Megacephala and the dark-coloured Cicindelidans towards Manticora with which the semicircle terminates at its lower extremity. To com- plete the circle it will be necessary to cast an eye over the other branch of the Geadephaga, the Eutrecha, and endeavour to discover which, amongst its different tribes, will best supply us with the means of doing it. Our eye probably might first be caught by the gigantic Anthie, and immediately we should be struck by a considerable resemblance between these, especially the males, and Manticora, and by a closer examination be convinced that they approached each other in the line of affinities; having found a link that connects with one end of our semicircle, we should next look round for some slender long-necked form to place next the other, and we should soon discover a group, consisting of several genera, in the same tribe with Anthia, that exhibited a most remarkable resemblance to the Col- liuridans ; wpon inspecting these more nearly we should select Agra as almost the counterpart of Colliuris, comparing the head, the neck, the elytra, and especially the tarsi, we should find them all formed upon the same plan, except that in Colli- uris the penultimate joint of the latter has only one lobe, which in 4gra is bilobed, and feel a strong conviction, that this agreement in structure was not merely an analogical resemblance,’ but an indication of close affinity. If we next look for some middle form, which, like Cicindela campestris, may be regarded as nearly equidistant from the two extremes, perhaps no better known genus could be selected than Calleida of De Jean, which, in colour, is almost as brilliant as a Cicindela ; and, in form, may be regarded as nearly the mean of the semicircle of Truncipennia to which it belongs. This is the present aspect of the central group and of the tribe which appears most nearly connected with it; but to what alterations future discoveries may open a door I will not presume to conjecture. It would be rash to affirm that insects may not be found to complete a separate circle both of Euptera and Truncipennia, but the above arrangement seems to follow from our present knowledge of them. 8 Mr. W. S. Mae Leay (Annulos. Javan. 8) seems to regard these as only analogical characters, but the points of agreement are too numerous for any thing but affinity. The agreement of these two genera in having all the tarsi of both sexes dilated, and furnished with a brush, with the penultimate joints lobed, is alone a sufficient proof. a 6 NORTHERN ZOOLOGY. I shall next proceed to state the result of my investigation with regard to affinities observable between other tribes of the Euptera and the Eutrecha. Mr. W.S. Mac Leay, in his arrangement, places Elaphrus next to the Cicindelidans,? and ° its claims to affinity with them can scarcely be doubted; but when we turn our attention to one of the Elaphridans described in this catalogue, Opisthius Rich- ardsoni, we find that the tribe is also connected by athnity with the Subulipalpi of Latreille, as Bembidium, &c. a further confirmation of this may be derived from an inspection of Ocydromus flavipes (Bembidium Steph.) which though clearly one: of the tribe last mentioned, is as clearly related to Elaphrus. It is evident there- fore that, by the Elaphridans, the Cicindelidans are connected with the Subulipalpi, which I cannot agree with Mr. Mac Leay in regarding as belonging to the Harpa- lide ; the Acutipalpi (Trechus and affinities) Subulipalpi and Elaphride appear to me to form a distinct tribe, consisting of Eutrecha delighting in humid places and constituting an intermediate or transition group (or perhaps a minor section which might be named Hygradephaga) usually consisting of small insects between the Geadephaga, or terrestrial, and the Hydradephaga, or aquatic, Predaceous Beetles. Here then we have a second series connected with Cicindela. Mr. Mac Leay considers the Carabidans as near in affinity to the Cicindelidans, nor am I disposed to deny that they make an approach towards them; for the males of both are Sarrothropodous, the nearest approximation to Cicindela that these make, as far as I have had an opportunity of examining the family, is by.Carabus splendens Oliv.! but this is still at a great distance and many forms are wanted to fill up the interval. The Carabidans go off one way towards the Cystipodous Dimani by the Chloniadans and so proceed to the Quadrimani, from which we may enter the osculant group of Elaphridans, &c. by Stenolophus which connects my Harpalidans with Trechus, &c. Thus we have three distinct tribes that branch from the typical group, but we seem to find nothing amongst the Bipartiti of Latreille to tend towards them, unless we may suppose Oxygnathus De Jean, and some of the other Scaritidans, to be connected with it by their mandibles. A circumstance however has been related of the larva of Aristus bucephalus which indicates some affinity between it and that of Cicindela ; we are told it has the same habits and form,” but to look at the perfect insects, we see little resemblance, except an approach in the form of the thorax 9 Annulos. Javan. 8. 1 Thisinsect is synonymous with that mentioned in the Introd. to Ent. (iv, 506, note) under the name of C. levigatus. 2 N. DH. N. ix, 510. Article Ditomus. ADEPHAGA. 7 to that of Manticora. Intervening forms may hereafter be found, which may connect it with that genus, which itself, in some respects, has the aspect of one of the Bipartiti, or Scaritide Mac Leay. From the above statement I trust it will appear evident that almost all the dif- ferent tribes of Geadephaga immediately connect with the Typical Group, or branch from it, and that it is impossible to describe them in the order in which they are arranged by nature, and that, therefore, the different authors who have written upon them are all correct in their views, though they have taken different routes in departing from the central station. ‘Thus Latreille, De Jean, and Ste- phens, are right when they assume the Yruncipennia as an evident affinity ; and Mr. Mac Leay also in going off by Elaphrus and Carabus and returning by the Brachinide and Anthia. Under the present head I may further observe with regard to the sculpture of the elytra of the present sub-section, that, with the exception of Manticora and Omophron, at least as far as an extensive examination enables me to decide, they all, if viewed under a very powerful magnifier, appear to consist of a most minutely and beautifully reticulated substance, chagrined, as it were, with innu- merable granules. In some, as Harpalus carbonarius, the Bembidiadans, &c. this circumstance is more conspicuous than in others, and it gives these animals a silky appearance; though most visible in the elytra, it may commonly be discovered in the head and prothorax. In the Hydradephaga it is most visible in the Gyrini- dans. It is not however confined to the Predaceous Beetles, since it may be discovered in the Buprestidans and many other Coleopterous insects. I shall here also observe once for all, that in all the Eutrecha, or Ground Beetles, that have a notch in their Cubit, with the exception of those whose elytra are distinguished by elevated ridges, as Anthia, Brachinus, and some others, near the margin of the elytra, where they are striated or furrowed, on the eighth furrow from the suture, or in the interval between it and the ninth, is usually a series of from twelve to thirty or more ocellated impressions, or impressions with an elevation in their centre, placed at various intervals, and sometimes only at the base and apex of the elytrum; those that have no notch in the cubit have usually no appearance of this kind, but in Cicindela these impressions, but without the central elevation, may be traced. The typical number of furrows, in the Ground Beetles is nine, but in Omophron, Calosoma Sycophanta and some others there are Sifteen. 8 NORTHERN ZOOLOGY. Family CICINDELIDZE. Cicindelidans. I.

Length of the body 62 lines. Locality not stated. DESCRIPTION. This species not a little resembles C. hybrida, but the labrum is prominent in the middle, and more conspicuously unidendate; the colour of its upper surface is browner with less of a purple tint; the prothorax is rather more hairy; the lateral margin of the elytra is white, from which proceed five white branches; the two first forming a humeral crescent with the lower limb bending obliquely towards the base of the elytrum, the third becoming a broken or S-shaped band, the extremity of which nearly reaches the suture; and the two last, forming a crescent at the apex of . the elytrum, to produce which the whiteness of the margin is subinterrupted: the suture terminates in a minute point, and the apex of the elytra is serrulate. Underneath the body is green or golden- green, with the sides rather more thickly covered with snowy hairs than in the other species of the genus. N. B. In the male the S-shaped band is interrupted. ' The larva of this genus, as well as that of Aristus, lies in wait for its prey, suspended by its dorsal hooks, in a little burrow it has formed. Its body is depressed. Its head corneous with eight eyes, the two external or lower ones being very minute. The plates that cover the trunk are coriaceous. The abdomen is fleshy, armed on its back with a pair of suspension-hooks. It has no anal processes. In many respects it exhibits an analogy both with spiders and the larva of the ant-lion. Our present acquaintance with the species of this splendid genus is not so intimate as might be expected, since we have not yet attained to such a knowledge of them as will enable the Entomologist to distinguish with certainty the species from the mere variety. Count De Jean (Species Général des Coléoptéres, i, and Supplement to ii) has described 144 species of the genus as now restricted ; but whoever looks at his specific characters will perceive that, in general, they are taken from the white spots or bands of the elytra. These by no means, however, afford a certain and constant diagnostic. For instance, one individual confessedly of the same species, will have a white humeral crescent, an angular or broken discoidal band, with a terminal crescent, all extremely well defined. Another will exhibit the same characters, but become less distinct, and more faintly traced ; in a third the humeral and terminal crescents of the elytra will have each become two distinct spots ; which in a fourth will altogether disappear ; lastly in a fifth, to name no more variations, the discoidal band will be almost, as it were, unbent. So that, in some species, without the aid of other characters, these markings of the elytra will often be insufficient. CICINDELIDZ. 9 (2) 2. CICINDELA REPANDA. (De Jean.) Wavy Cicindela. Cicindela repanda. De J. Coléopt. i, 74? Length of the body 51—6 lines. Locality not stated. DESCRIPTION. Very like the preceding species, but the labrum is shorter and less prominent in the middle; the lateral margin of the elytra is not continuously white; the lower limb of the humeral crescent slopes towards the apex of the elytruam; the broken or S-shaped band terminates in a streak at the margin: all the markings also of the elytra are buff-coloured rather than white; and the minute mucro or point that terminates the suture, and the serrulations of the apex of the elytra, are less conspicuous. De Jean regards this species as synonymous with C. hirticollis, but, if I am correct in my refer- ence to him, of which I have little doubt, they are clearly distinct. (3) 3.* CicinDELA Proteus. Proteus Cicindela. C. (Proteus) labro unidentato medio subprominulo, supra fusco-cuprea, elytris punctis quatuor, fusciaque media fracta, albis. Proteus Cicindela, with the labrum unidentate, rather prominent in the middle; above brown-copper, elytra with four white dots and a mesal broken white band. Length of the body 53 lines. This species, of which several specimens were taken in the Expedition, appears to abound in North America. Dr. Bigsby met with it in Canada, and there was a specimen in the late Mr. Marsham’s collection probably from the United States. DESCRIPTION. Similar to C. repanda, but instead of the humeral and terminal crescents, in all the varieties, are four white dots, two at the base and two at the apex of the elytra; the middle broken or tortuous band resembles the figure 7 reversed, and does not terminate in a marginal streak.

DESCRIPTION. Very nearly related to C. obliqguata and regarded by Count De Jean as synonymous with it. They differ however in the following particulars. In C. vulgaris the upper surface of the body is nearly black, without any tint of bronzed-green. The humeral crescent of the elytra is slenderer, and its lower extremity does not approach so near the mesal band. In the females the intermediate joint of the labial palpi is black. In the males the underside of the body, with the exception of the anus, is of a fine blue instead of a golden-green. i CICINDELIDZ. ll (6) 6. CicINDELA PURPUREA. (Olivier.) Purple Cicindela.

Sheppard, F.1.s. of his Majesty’s Royal Regiment of Artillery. I have also received it from various other parts of North America. The green varieties of this species seem to be the American representatives of C. campestris so common in England and all Europe. As this species varies greatly, I shall take my description from Capt. Sheppard’s specimen, which may be regarded as the most perfect type of the species. DESCRIPTION. “ Body underneath with the trunk resplendent with green, gold, and copper,—abdomen, with the exception of the green anal segment, blue; above purple with the base and apex of the prothorax green; the suture of the elytra is also green, and adjoining to the lateral margin is a blue and green longitudinal stripe; at the base of the elytra is a humeral dot, a little before the middle near the margin a round spot, in the middle a bent band, below this another round spot, and at the apex a triangular one, all pale buff-coloured and distinctly marked. Variety. B. g. In this the spots and band of the elytra are the same in number and situation, but not so broadly traced asin A. The humeral dot is also larger than the marginal one between it and the band. ‘Taken in Canada by Dr. Bigsby. C. ¢. Lateral stripe of the elytra all green; spotted as in B, but the humeral spot is of the same size as the succeeding one. In Mr. Marsham’s collection. D. ¢. Elytra without the humeral and first marginal spots; the other spots as in variety B, except that the band does not approach the lateral margin. E. 3d. ¢. Elytra with a discoidal oblique and apical transverse streak. Taken in the expedition, and in New England, by Professor Peck. F. ¢. Elytra purple tinted with green, lateral stripe blue and green; discoidal band sinuated; no humeral or marginal spots: apical as in the type. Taken in Canada by Dr. Bigsby. G. ¢. Elytra entirely green, spotted like variety D. H. 3. ¢. Elytra green with a blue marginal stripe, spotted like variety E. Taken in the Expedition, and in New Jersey by Mr. Drake. The transition from the fully characterized type of the present species to those varieties with only ' two spots, and from them, by means of variety F, to those with green elytra, is so gradual as to convince any careful inspector of them, that all belong to one species: yet a person who had never examined the intermediate varieties would seemingly have good reason for considering them as forming, at least, three distinct ones.

This species, though apparently common in North America, is not noticed by Say, who perhaps mistook it for C. sylvatica Linn. of which it may be regarded as the American representative, and with which it agrees in its prominent upper lip, and the shallow impressions and markings of its elytra, as well as nearly in its general colour. But besides its smaller size, it differs from it mate- rially in having a white instead of a black upper lip with an obtuse longitudinal ridge and not an acute one, terminating in three almost obsolete short teeth instead of a single longer one; and likewise by the want of the silky lustre produced by granulations much more visible, which distin- guishes the elytra of C. sylvatica.

Prothorax short, channelled, widest anteriorly: with the angles rounded. Llytra obliquely truncated at the apex, and emarginate, so that internally they terminate in an acumen. Cubit emarginate. Tarsi with the penultimate joint entire. Claws single, not pectinated. The maxillary palpi of the genus here defined present an anomaly observed in no other known coleopterous genus, they appear to be furnished with a minute fifth joint retractile within the fourth. In one of these palpi, in the only specimen taken, this little accessory joint is not apparent, but in the other it is distinctly seen emerging from the fourth joint, or rather, as this last appears broken at the apex, it is uncovered. ‘There is only one supposition that can reconcile this case to the general rule, that no coleopterous maxillary palpus shall exceed four joints, namely—that this is an effort of nature, by a reproduction, to restore the mutilated organ so as to fulfil its functions. Did the insect belong to the Crustacea or Arachnida this would be a satisfactory explanation of the anomaly, but _I do not recollect any instance upon record of a genuine insect having reproduced a lost organ. I thought it possible that the palpi of other Predaceous beetles might contain a retractile joint,’ and this truncated apex seemed in some degree to favour the idea, but I did not succeed in my endea- vours to discover one. The above structure of the palpi, if not accidental, seems to give our little insect some affinity with the Subulipalpi of Latreille, but its general characters and aspect appear to demand a place for it somewhere between those Truncipennia whose claws are not pectinated, and those who have those organs so armed.

PLATE I, FIG. 2. Length of the body 33 lines. Only a single specimen taken. Mr. Drummond, in answer to my queries with respect to this, and some others of the more remarkable insects taken in the Expedition, observes, upon reading my description of this insect, that it agrees with one taken on the sandy shores of Lake Winnipeg in the spring of 1825, that it runs on the sands with great agility, and frequently flies when attempted to be taken. But this statement agrees so precisely with the motions of Bembidium impressum as described by Linné and Gyllenhal (see under that insect) that I suspect Mr. Drummond had his eye to it, rather than Sericoda. 16 NORTHERN ZOOLOGY. DESCRIPTION. Body underneath black, glossy; above the black has a brassy tint, with somewhat of the lustre of silk: head, between the eyes, marked with a short, anteriorly forked furrow: prothorax sub- trapezoidal, anteriorly subemarginate, sides oblique with the margin reflexed, transversely very minutely wrinkled, with a pair of anterior excavations in the disk, posteriorly also somewhat impressed on each side: elytra longer than the head and prothorax together, slightly furrowed with impunc- tured furrows, obsoletely clouded; there is a series of about five shallow impressions near the suture.

Several specimens of this insect were taken in the Journey from New York to Cumberland-house, and in Lat. 54°; Mr. Nuttall took it near the Missouri; and Mr. Say in great numbers near Engineer Cantonment, where they were found hybernating in the fissures of a stone-quarry; it was taken also in Canada by Dr. Bigsby. DESCRIPTION. This species is very closely allied to B. crepitans, common in England and all Europe, but the second and third, as well as the other joints of the antenna are red: the principal distinctiou, how- ever, is in the shape of the prothorax, which is shorter, anteriorly more dilated, and the posterior angles are more prominent: it is scarcely half the size of its compatriot B. fumans, and differs from that, and all other Brachini that I have examined, in having the thin white membrane that termi- nates the elytra, especially at their internal angle, much longer and more conspicuous; this mem- brane, which is a continuation of the hypoderma or lining of the elytra, is but just discoverable in B. crepitans ; the extreme base of these organs is testaceous: the underside of the abdomen is rufo-piceous. In other characters this insect agrees with the species last named. 7 As many species have blue elytra this name is not sufficiently distinctive.

Head punctured between the eyes with confluent but not minute punctures; anterior part of the front wrinkled on each side, but the nose and upper-lip are quite smooth; the seven terminal joints of the antenne are brown: the prothorax is nearly square with the sides rounded anteriorly and the posterior angles a little prominent; it is deeply channelled, transversely wrinkled in the disk, confluently but not minutely punctured on the sides; the disk also is black, but the sides exhibit shades of dark blue and green, at the margin they are of a most brilliant ruddy copper, some of the anterior punctures also appear as if gilded: the elytra are rough and as it were reticulated with longitudinal and transverse elevations, the former nearly arranged in lines which produce deep cavities; the disk is of a fine deep blue, the sides green and the lateral margin of the same ruddy copper as that of the prothorax. The body underneath is quite smooth in the disk, with some irregular elevations and depressions on the sides: the sides of the antepectus, or forebreast, are of a fine green; the intermediate segments have each a pair of impressions from which a hair emerges. This is most visible in the male. I at first regarded this splendid insect as a new species. I thought it, indeed, very near Carabus Vietinghovii, but as it did not altogether agree either with Dr. Fischer’s figure or description, and was found in another quarter of the globe, I regarded it as distinct; but having received from my friend Mr. Hope, a Russian specimen of that insect, I find no difference sufficient to constitute a species. In that specimen the marginal gilding of the prothorax and elytra is greener with scarcely any of the ruddy hue of copper which gives such brilliance to the American specimen. It has been observed that the plants on the other side of the rocky mountains are of an Asiatic type, and the present animal, and some others I shall hereafter notice, furnish a proof that several of the insects are similarly cireumstanced. The sculpture of the elytra of this species is precisely that of a Procerus, to which genus I at first referred it, but the tarsi of the male are dilated which is the character assigned to Carabus. ‘The only specimen taken was brought over in spirits, and affords a striking proof of the excellence as well as convenience of that mode of destroying and preserving beetles for D 18 NORTHERN ZOOLOGY. transportation. It has been in my custody more than tweive months since it was taken out of the spirits, and it has never been at all mouldy, nor has it ever suffered from the attack of Acari, &c. from which other insects preserved with it have not escaped, which leads me to conjecture that immersion in spirits, if for a sufficiently long period, renders an insect distasteful to the little devastators of our cabinets.

DESCRIPTION. Body black and glossy. Head oblong, impunctured, separated from the neck by a transverse slender curving ridge forming anteriorly a deep sinus; ridge, defending the base of the antenne, conspicuous; frontal impressions long, not deep; antenne not much longer than the prothorax : prothorax nearly square, black slightly bronzed; sides lightly punctured, lateral margin reflexed ; it is faintly channelled, depressed transversely at the base, with a punctured impression on each side : elytra bronzed, subdepressed with scarcely any sinus at the apex, lateral margin reflexed and cari- nated: each elytrum with thirteen or fourteen rows of impressed punctures ; a triple series of oblong discoidal elevations; interstices with numerous transverse linear impressions: abdomen underneath smooth with a few minute punctures on the sides. The insect here described agrees with Germar’s description of Knoch’s C. ligatus, but it is doubt- ful whether it be synonymous with C. carinatus of De Jean. In most respects, indeed, it accords precisely with his description, but the head is not slightly punctured, as he states his specimens to be. VII. Genus CALOSOMA. Fab. i. * Subgenus. CurysosticMa.

Archn. et Ins. i, 401,*) but it seems to have escaped this learned and acute Entomologist, that in these genera, though the form of the dilated joints of the hand of the males differs from that of his Simplicimani, yet that underneath, like them they are furnished, not with a brush like the last named genera, but with little membranous bags or cysts. * I have quoted this work under the title which M. Latreille himself affixed to those copies that were presented to his friends or sold separately—viz. Les Crustacés, Les Arachnides et Les Insectes, forming two volumes per se, and the 4th and Sth of Baron Cuvier’s 2nd edition of the Régne Animal. 24. NORTHERN ZOOLOGY. DESCRIPTION.

Several specimens taken in Lat. 54°. 2 Anchomenus differs from Agonum in scarcely any respect, except in having the posterior angles of the prothorax less rounded, and as it is closely connected with it by those species, which like Agonum picipes have a longer prothorax, I con- sider it merely as a subgenus. AGONID. 25 DESCRIPTION. Body black, glossy. Mouth and its organs rufous, except the upper-lip which is edged with that colour; antenne longer than the prothorax, piceous with the scape paler than the other joints : prothorax longer than in the following species, oblong-ovate, with the lateral margin piceous, and not dilated posteriorly as in the majority ; basilar impressions rather shallow, oblong: elytra oblong, rufo-piceous, slightly furrowed, furrows impunctured; five punctiform impressions between the second and third; the three anterior ones adjacent to the latter, and the two posterior to the former: legs dusky rufous. Variety B, With only four punctiform impressions, legs paler. C. With the second, third, and fourth joints of the antenne piceous, the rest ferrugi- nous: impressions of the elytra as in B. D.

Body black, glossy. Mandibles at the tip, mouth and scape of the antennz, piceous: prothorax nearly as long as wide; disk transversely wrinkled; lateral margin at the base much dilated, rather incrassated, and subangular ; posterior impressions large and distinctly punctured : elytra wider than the prothorax, subemarginate at the base; distinctly furrowed with very minute and inconspicuous punctures in the furrows; three punctiform impressions in the third furrow from the suture: legs piceous. This species is the American representative of A. versutum, which it much resembles. It is however larger, the transverse wrinkles of the disk of the prothorax, and the punctures in its posterior impressions, are more distinct; the furrows of the elytra are rather deeper with more convex inter- stices, and the three punctiform impressions are all adjacent to the third furrow, whereas in A. ver- sutum the anterior one alone is adjacent to that furrow, the two other adjoining the second.

Half-glossy Agonum, glossy, black underneath, head and prothorax greenish-bronzed ; elytra more obscure, black-bronzed, with five punctiform impressions. Length of the body 44 lines. Taken in Lat. 54°. j DESCRIPTION. Body smooth, glossy, black underneath. Head greenish-bronzed, very glossy, with frontal im- pressions lunular ; antenne longer than the prothorax: prothorax greenish-bronzed with a copper tint, very glossy, channelled, disk transversely and minutely wrinkled ; basilar impressions longitu- dinal, lateral margin, particularly at the base, reflexed: elytra black-bronzed, less glossy than the head and prothorax, lightly furrowed; furrows punctured ; in the insterstice between the second and third furrows are five punctiform impressions, two nearer the base and three nearer the apex of the elytrum, so that the interval between the second and third is greater than that between the others. Variety B. Second and third punctiform impressions not more distant than the others. In this specimen, on the left hand elytrum, there are only four impressions, and on the other five, but in neither are the second and third situated asin A. It may he a distinct species, but I can discover no other difference. wo SI AGONIDEE. (30) 6.* Aconum siImiLe. Similar Agonum. A.

Similar Agonum, glossy, underneath very black, above a little bronzed ; elytra with the sutural furrow deeper than the rest, marked with five punctiform impressions. Length of the body 33 lines. Locality not stated. DESCRIPTION. Body glossy, underneath very black, above black slightly bronzed. Antenne scarcely longer than the prothorax: prothorax rather longer than broad; basilar impressions roundish, impunctured: elytra more bronzed than the head and prothorax, lightly furrowed ; furrow adjoining the suture more depressed and deeper than the rest; in the space between the second and third furrows are five equidistant punctiform impressions, the two anterior adjoining the latter furrow, and the three posterior the former. This little species greatly resembles 4. seminitidum. It is however much smaller, less bronzed, the prothorax is longer in proportion, the sutural furrow is deeper, and the impressions are differently arranged. (31) 7.* AGonuM AFFINE. Kindred Agonum. A.

Length of the body 33 lines, Taken in Lat. 54°. DESCRIPTION. This species approaches very near to the preceding one, and its place is between that and A. ver- nalis, of which last it is the American representative. It differs from ? > > obtusangular sinus; prothorax transverse. Length of the body 5 lines. One specimen only taken. DESCRIPTION. This species has a good deal the aspect of Bradytus apricarius, but it is a larger insect and rather wider in proportion; and the bifid intermediate tooth of the lower lip proves that it is a true Curtonotus. Body piceous, above bronzed. Upper-lip, palpi, antennz, side-covers, and legs all rufous, nose at the anterior margin has an obtusangular sinus; frontal impressions punctiform con- nected by a slightly-drawn line or furrow: prothorax wider than long, the lateral margins forming a segment of a circle without any posterior constriction; at the base the prothorax is depressed, the basilar impressions are bisulcate, the inner furrow being the longest: furrows of the elytra punctured.

In other respects it resembles H. pleuriticus. G 49 NORTHERN ZOOLOGY. (59) 3. * Harpatus ocuropus. Ochre-legged Harpalus.

Upper-lip piceous; antenne, palpi, and legs reddish-tawny, the first longer than the prothorax; the nose terminates anteriorly in a reddish membrane or rhinarium: prothorax qua- drangular with all the angles rounded, rather longer than wide; dorsal channel anteriorly abbrevi- ated; lateral margin minutely punctured, much depressed, especially at the posterior angles; basilar impressions double, shallow, and minutely punctured : elytra very little glossed, more than twice the length of the prothorax, furrows impunctured with convex interstices, the lateral ones with some scattered very minute punctures ; the vesicles on the sole of the four anterior tarsi of the male are arranged as in the other Harpali. Both the specimens taken in the Expedition are males, or I should have supposed the unusual difference in their size was sexual, probably the small one was taken in a higher latitude.

This Section consists of the littoral or subaquatic ddephaga. It may be di- vided, with one anomaly, into three minor sections distinguished by their palpi, which may be denominated—1, Acutipalpia, 2, Subulipalpia, and 3, Filipalpia. Amongst these we seem to have a representative, in miniature, of many of the Geadephagous tribes and genera—Thus, e.g. Elaphrus represents Cicindela; Opis- thius or Bembidium, Calosoma; Notiophilus, in some sort, Carabus ; Catascopus and Pseudomorpha® the Truncipennia; Stenolophus the Harpalide ; Isopleurus the Cystopodous Dimana; and Lopha perhaps the Bipartita. Probably further inves- tigation may make it evident, that Argutor also belongs to this subtribe. ° Linn. Trans. xiv, 94, t. iii, f. i, and 98, t. iii, fi 3. 46 NORTHERN ZOOLOGY. Family STENOLOPHID.

Red-shanked Trechus, black, rather glossy; palpi at the apex, antenne at the base, and tibi, rufous; prothorax rather square, with a basilar furrow on each side; elytra with a single punctiform impression ; margins of the apex rufous, ; Length of the body 2% lines. Only a single specimen taken. 1 M. Latreille (Crust. Arachn. et Ins. i, 391) has placed this genus at a considerable distance from Zvrechus, though he appears aware of their aflinity; but Mr. Stephens has properly inserted it between Ophonus and the latter genus. He has, however, in his characters of Stenolophus omitted to notice its most striking distinction, that in the male insect the penultimate joint of the four anterior tarsi is cleft to the base into two narrow lobes. In Harpalus and Ophonus this joint is heart-shaped. The last joint of the palpi in the present genus, is conical though subtruncated and belongs to this tribe. 2 Mr. Stephens (Illustr. Mandib. i, 167) says that the four anterior tarsi in Trechus are dilated in the males, which would make them belong to the preceding stirps, but this is an oversight, for only the anterior pair or hands are dilated. See Sturm. Deutsch. Fn. v, t. cxlix—cli. f 3 The four first joints are dilated in the hands of the males in this genus. TRECHIDZ. 47 DESCRIPTION. This species upon a slight inspection might -be mistaken for an Argutor,* but it exhibits all the most important characters of the genus under which I have placed it. The body is black, some- what glossy. The tip of the palpi and scape of the antennez are rufous: the prothorax is rather wider than long, but nearly square; the short basilar furrows observable in Argutor distinguish this species from the succeeding ones: elytra lightly furrowed, furrows impunctured; in the usual situa- tion adjacent to the second furrow a little beyond the middle of the elytrum a very minute puncti- form impression is just discernible; the lateral margin and suture at the apex of the elytra are reddish: the tibie are rufous but the cubit is black at the tip; the tarsi are darker, the hand has four dilated joints as in the other species of the genus. (68) 2.* Trecuus ruFicrus. Red-legged Trechus. T. (ruficrus) niger; antennis scapo, pedibus, prothoracisque margine, rufis: elytris luridis : litura pone medium nigricanii. Red-legged Trechus, black; scape of the antennz, legs, and margin of the prothorax, rufous ; elytra lurid with a blackish blotch beyond the middle. Length of the body 24 lines. One specimen only taken. DESCRIPTION. Body black, glossy. Palpi piceous; scape of the antenne and mouth rufous: prothorax subob- cordate; channelled, channel not abbreviated, margin rufous especially the basilar; angles rounded ; basilar impressions single, round, and punctured: elytra lurid or dirty yellow with a large blackish cloud or blotch beyond the middle: legs dull rufous, thighs darker.

Yellow-legged Trechus, piceous, glossy; head underneath, mouth, antenne, prothorax, limb of the elytra, more or less rufous ; palpi and legs yellow. Length of the body 24 lines. Many taken in Lat. 54°. 4 I suspect that the genus here quoted, consisting also of minute species, and inbabiting moist places, (see above p. 30, note 5) belongs rather to the present subsection than to the Geadephaga ; Trechus tibialis seems to lead from Argutor to Trechus. 48 NORTHERN ZOOLOGY. DESCRIPTION. Body piceous, glossy. Head underneath, nose, mouth, and oral organs—except the palpi which are pale yellow—and antenne rufous; three first joints of the latter paler than the others: pro- thorax rufous, rather longer than wide, between square and obcordate ; basilar impressions single, very slight, punctured, and black: elytra rufous, with a broad black stripe adjoining the suture and parallel with it; furrows rather deep, impunctured: legs pale yellow. N.B. In the majority of specimens the black stripe of the elytra is very faint, and in some evanescent, and the impressions as well as the rest of the prothorax rufous. (70) 4. * Trecuus immunis. Lmpunctured Trechus. T. (immunis) piceus, nitidus ; ore, antennis, pedibusque, rufis; prothorace obscure rufo ; foveis posticis impressis, levibus.

Two specimens taken with the preceding species. DESCRIPTION. Similar to 7. flavipes but smaller, the nose is piceous, the thorax is more dusky; dorsal channel indistinct ; basilar impressions deeper and impunctured: elytra dark piceous with merely the bead of the lateral margin rufous; the furrows also are more lightly drawn: legs darker. (71) 5. * Trecuus simitis. Similar Trechus. T. (similis) niger, nitidus ; ore, antennis, prothoracis elytrorumque limbo, pedibusque, flavo-rufis ; prothorace postice punctulato. Similar Trechus, black, glossy; mouth, antenne, limb of the prothorax and elytra, and legs, reddish-yellow ; prothorax punctured at the base. Length of the body 33 lines. Two specimens taken in Lat. 54°. DESCRIPTION. Body black, glossy. Mouth reddish yellow; palpi yellow; -upper-lip and mandibles rufous, the latter black at the tip; antenne dusky-rufous, three first joints more yellow: prothorax between obcordate and square, with the whole of the base distinctly and grossly punctured ; basilar impres- sions shallow; limb of the prothorax is reddish-yellow, the disk is occupied by a large square black spot : the suture, lateral margin, and apex widely, and the inner base of the elytra, are reddish-yellow ; ISOPLEURID. 49 adjoining to the suture is a broad black stripe not reaching the apex; the furrows are rather deep and impunctured; and in the usual situation, a little beyond the middle, a punctiform impression is adjacent to the second furrow: the sides of the fore-breast, the anus, and the legs, are reddish- yellow. Variety B. Thorax without a black spot in the disk, body underneath piceous. This species, though very like 7. flavipes, is quite distinct from it; it is nearly related also to T. flavicollis of Sturm,° but it is much larger, the three first joints of the antenne, and not the scape only, are paler than the others; and the prothorax is transversely Hunctezed at the base, which in that species is impunctured.

Palpi mazillary, antepenultimate joint longer than the rest, pega ae penultimate shorter than the last joint, obconical ; last semi-ovate, aihtrancate? labial, penultimate joint pnees than the rest, subclavate; the last semilanceolate, subacute.® Labium deeply emarginate sometimes with a short intermediate denticle, or prominence. Tongue shorter than the paraglosse. Antenne three first joints glossy, the third very little longer than the subsequent ones. Bdoy \inear-oblong. Head subtriangular; frontal impressions punctiform. Prothorax subqua- drate, rather narrowest anteriorly; sides curving: base as wide as the elytra. Scutellum wider than long. Elytra with the sides parallel, very slightly sinuated at the apex. Hand of the males with three dilated joints. I know two species belonging to this genus, one taken by Mr. Drummond, in the late Expedi- tion, amongst the Rocky Mountains, and the other, which is in my own cabinet, I judge from the pin with which it is transfixed, to have been taken in the East Indies by Major General Hardwicke, and probably given by him to the late Mr. Marsham, at the sale of whose cabinet, though I have no memorandum of the fact, I suspect I purchased it. If this conjecture turns out correct, this is an instance of another Oriental form from the above mountains, and confirms a remark Mr. Sabine once made to me, that the natural productions, he spoke of the plants, on their western side appeared of an Asiatic type. It should be observed however that the Asiatic species differs from the American in having no prominence in the sinus of the labium, its maxillary palpi also are less acute, and the prothorax not so narrow before, or more approaching to a square, so that perhaps it may form a subgenus in the Isopleuridans. This genus seems to have some relationship to Amara. ° Deutsch. Fn. v, 87, 11, t. cli, f. c. ° The Trechidans and Isopleuridans cannot be included in one family because the former has four dilated joints in the hand of the male insect and the latter only three, I placed Stenolophus next to Harpalus, because the males of both agree in being quadrimanous, or having four dilated tarsi; yet I am rather inclined to think that Zsoplewrus and Trechus, as repre- senting the Dimanous Geadephaga, ought to be placed first. 7 Plate I, Fig. 6 a. 8 Ibid. 6.

Family PATROBIDE. Patrobidans. XXIV. Genus PATROBUS. Meg. I consider the Patrobidans as forming a family distinct from the Pogonidans, though both agree in having only two dilated joints in the hand of the males, be- cause the former have the last joint of the palpi more or less conical and acute ; and. in the other they are filiform and truncate. De Jean has formed his first division of his Feronians of these two families, the last of which, the Pogonidans, consists of the modern genera Pogonus, Cardiaderus, Blemus, Epaphius, and Aepus; 9 The following is a description of the Oriental species :— * Isoprrunus Mac Lrayi. Mac Leay’s Isopleurus. I. (Mac Leayi) niger, nitidus, supra eneus ; ore, palpis, antennis scapo, pedibusque, rufo-flavis ; elytris apice pallidis, latere externo brevissime pilosis, striatis : striis secundo, tertio, et septimo foveolis octo impressis- Mac Leay’s Isopleurus, black, glossy, above bronzed; mouth, palpi, scape of the antennz and legs reddish-yellow ; elytra pale at the tip ; at the lateral margin hairy with very short hairs ; lightly furrowed; second, third, and seventh furrows with eight punctiform impressions. ’ PATROBIDZ. 51 and the first, the Patrobidans, of Baripus and Patrobus.! Pogonus, &c. are not very distant from Trechus and Isopleurus; they belong as clearly to the Hygradephaga, and as clearly lead to the Patrobidwe, which though of greater size than most of the constituents of that subsection, maintain, as far as they are known, the same love of humid and littoral stations, and, though differing in their palpi and size, are nearly related to the Subulipalpia: the discovery of a very few intermediate links would connect Patrobus and Peryphus; and even now, if closely inspected and compared, they will be found to possess many characters in common. In the first place, in the tribe to which Peryphus belongs, in the males, the two first joints of the hand are dilated, the second indeed only on one side, and cystophorous, as in Patrobus: in the next, the head and eyes in both are very similar as to form and likewise sculpture, and the same may be said of the prothorax and elytra. DESCRIPTION. Antenne, the scape excepted, dusky-rufous, rather longer than the prothorax ; joints that suc- ceed the third thicker than the basal ones: prothorax wider than long, impunctured ;_ basilar impres- sions single, slight : elytra furrowed; furrows lightly drawn, impunctured ; on each of the following furrows, viz. the 2nd, 5th, and 7th, are eight punctiform impressions ; epipleura pale yellow.

Body glossy, underneath black, above black-bronzed with a slight greenish tint. Head triangular, with a thick convex neck ; frontal impressions long and deep; antenne longer than the prothorax, third joint of the length of the succeeding ones; scape and palpi rufous: prethorax obcordate con- vex, at the base depressed, constricted, and grossly punctured; dorsal channel as in Patrobus ; basilar impressions single, round, and deepish: elytra slightly furrowed with the furrows punctured ; the seventh from the suture nearly obliterated; apex nearly smooth, near which is an oblique pale spot: legs rufous with darker thighs, especially in the middle.

Length of the body 3 lines. A single specimen in Lat. 54°. DESCRIPTION. This so nearly resembles P. bimaculatus, that I first put it aside as an immature specimen, but further consideration induces me to consider it as distinct. It is wholly pale rufous, except the head the prothorax and the anus: the three first joints of the antenne and the base of the fourth are also rufous: the prothorax appears rather narrower in proportion, and less distinctiy punctured at the base; the spot at the apex of the elytra is larger; and the thighs are rather slenderer. 2 The Peryphide are distinguished from the Bembidiade, not only by the shape of the thorax, but by naane the apex and sides of the elytra smooth, or with obliterated furrows. v Or SN) PERYPHIDZ.

Scopuline Peryphus, black, glossy: head and prothorax bronzed with a slight tint of green; three first joints of the antenne, palpi, and legs rufous; elytra brown-bronzed with two punctiform impressions, and an oblique lurid spot near the apex. Length of the body 23 lines. Two specimens taken in Lat. 54°. DESCRIPTION. This species, though related to them, is distinct from the two preceding ones ; it approaches very near P. littoralis, probably synonymous with Carabus rupestris Fab., but the elytra have no ‘spot at the base, and in the usual situation, but adjacent to the third furrow, are two punctiform im- pressions, not to be discovered in that species. The body, head, and prothorax do not differ either in colour or sculpture from P. bimaculatus, but the palpi are considerably shorter, the three first joints of the antenne are rufous, the thighs are not darker than the rest of the leg: the elytra are of a dark mahogany-brown a little bronzed, with rather deeper furrows and punctures.

Length of the body 23 lines. Taken abundantly in Lat. 54°. and 65°. DESCRIPTION. This little species appears to be the American representative of P. littoralis, which in many respects it closely resembles. It is however a smaller insect, the body is invariably piceous or rufo- piceous, and the head and prothorax are of the same colour bronzed; the antenne are ferruginous with the scape paler: the prothorax is rather shorter. 54 NORTHERN ZOOLOGY.

Head and prothorax bronzed-green ; four first joints of the antenne rufous, the succeeding ones dusky; palpi rufous dusky at the tip; frontal impressions rather oblique: pro- thorax very meh constricted behind, so as to appear almost triangular, depressed at the base with a transverse series of punctures ; basilar impressions small: elytra piceous faintly bronzed, with a large roundish pale spot at the base, and another smaller, rather transverse one, beyond the middle; they are not furrowed, but have the usual number of rows of punctures which do not extend to the apex, and the lateral one is nearly obliterated: the legs are rufous. iv. * Subgenus EupRomus. Prothorax nearly square, with double basilar impressions. Elytra with only the disk punctured in rows. This subgenus differs from the other Peryphide in having a prothorax precisely resembling that of a Pecilus, of which genus it may be regarded as the analogue amongst the Subulipalpia.

XXVI. * Genus TACHYTA. Palpi with the last joint most minute, and with difficulty discoverable.3 Antenne subfiliform, submoniliform, with all the joints nearly equal in length. Body oblong, subdepressed. Prothorax narrower than the elytra, rather obcordate. Elytra obsoletely furrowed. This appears entitled to rank as a genus in a modern system, not only from having the last joint of the palpi much shorter and more minute than the other Peryphidans, but likewise from its moniliform antenna. It seems to approach to Tachys, but the prothorax is of a different shape coming near that of Bradytus and Curtonotus. It seems to be the analogue of Dromiustrunca- tellus and afhnities.

Black-foot Notaphus, black, glossy; above bronzed with a greenish tint; elytra with a basilar streak, two bands, the posterior undulated, and the tips, lurid. Length of the body 2 lines. Three specimens taken in Lat. 54°. DESCRIPTION. Body black, glossy ; above bronzed with a greenish tint ; the whole upper-surface under a pow- erful magnifier appears covered with innumerable granules, which are much more distinctly seen in this family than in the Peryphide. Scape of the antenna, which are longer than the prothorax, rufo-piceous ; frontal impressions parallel; the punctiform impression adjoining the eyes on their inner side has a central elevation: prothorax short with a deep dorsal channel; basilar impressions double with a little ridge between the external one and the margin : elytra furrowed, furrows punc- tured for about two-thirds of their length, the first and second reach the apex where they are con- fluent; the third and fourth stop a little short of the apex and are also confluent, as are the fifth and sixth, which are still shorter, and terminate in a little furrow common to both; the seventh and eighth reach the apex where they likewise unite; two punctiform impressions, in the usual situation, adjoin the third furrow; at the base of the elytrum, in the interstice between the fifth and sixth furrows, is a longitudinal lurid streak, then follows an abbreviated and articulate® band of the same colour, consisting of four streaks, those near the lateral margin being much the longest; in the interstices between the second and third furrows are two such little streaks; near the apex is like- wise another band both articulated and undulated, consisting of seven spots, the marginal one being rather the longest; the tips of the elytra are likewise lurid. N. nigripes is related to N. ustulatus, and appears to be its American representative; it differs from it in having black legs, and the lurid markings of the elytra are different: it comes nearest to Gyllenhal’s Variety C.6 + The Bembidiade are distinguished from the Peryphide by the elytra having the typical number of furrows, none being obliterated. 3 Introd. to Ent. iv. 297, c. 6 Insect.

(intermedius) niger, nitidus ; capite prothoraceque viridi-eneis ; elytris luridis eneo-nitidis ; maculis duabus, fasciaque inter- media, nigris ; antennis scapo, palpis, pedibusque, rufis. Intermediate Notaphus, black, glossy ; head and prothorax green-bronzed ; elytra lurid glossed with bronze, with two black spots, and a black intermediate band; scape of the antenne, palpi, and legs, rufous. Length of the body 12 lines. A single specimen taken in Lat. 54°. DESCRIPTION. Very nearly related to N. nigripes, but the head and prothorax are greener; antenne as long as the prothorax; the palpi are rufous with the penultimate joint rather dusky: elytra bronzed-lurid with a round black spot near the base, a larger near the apex, and an angular band of the same colour between them: the legs are dull rufous. ‘The sculpture of the elytra is nearly the same as in that species, but the fifth furrow by a turn outward almost intercepts the sixth and seventh, and then runs to the apex of the elytrum; the furrows themselves are black. (85) 3. * Norapuus varieGatus. Variegated Notaphus. N. (variegatus) niger, nitidus ; supra nigro-a@neus ; antennis scapo, pedibusque rufo-piceis ; elytris luridis nigro variegatis, striatis : striis abbreviatis ; trifoveolatis. Variegated Notaphus, black, glossy ; above black-bronzed; scape of the antenne and legs rufo-piceous ; elytra lurid, varie- gated with black ; furrowed, furrows abbreviated, trifoveolate. Length of the body 13 lines. DESCRIPTION. This also is related to N. nigripes, but is quite distinct. The head and prothorax are without any green tint; the antenne are not longer than the prothorax, the prothorax is proportionally not so wide before and narrower behind: elytra scarcely at all bronzed; lurid with a large blackish cloud or spot near the base, another near the apex, and an intermediate black angular band; the furrows of the elytra, especially the external ones, do not reach the apex, or at least are obliterated; they are punctured the whole of their apparent length; instead of two, there are three punctiform impressions: the legs are rufo-piceous.

In Canada. Dr. Bigsby. This little insect appears pretty generally dispersed. In England it has been rarely met with; the only known British specimen was in the late Mr. Marsham’s collection, and is now in Mr. Stephens’. The former gentleman, in his description, refers to Mr. Donovan’s cabinet. I have seen specimens taken by Mr. Wilkin in Flanders; and Oliver informs us, for there can be no doubt with respect to his synonym, though hitherto overlooked by Entomologists, that it is found on the banks of the Seine near Paris. It is found in Sweden, Major Gyllenhal informs us, on the sandy shores of lakes, where it is remarkable, in warm weather, for the promptitude and celerity of its motions both on the earth and in the air: and Mr. Drummond observes, I have no doubt with respect to this insect rather than Ser7- coda bembidioides,’ “ that it runs in the sand with great agility, and frequently flies when attempted to be taken.” Linné also observes of his Carabus velox, which the Entomologists of Sweden hold to be a variety of it, that it runs and flies with the most velocity of any coleopterous insect: a circumstance, which as well as its large eyes, proves its title, in common with Elaphrus, to claim some affinity with the Euptera, (Cicindela L.) 7 See above p. 15. 60 NORTHERN ZOOLOGY. DESCRIPTION, Body underneath green, bronzed, very glossy; above bronzed, gloss much obscured, occasioned by an infinity of most minute reticulations visible only under a good magnifier, which give it a granu- lated appearance ; frontal impressions and ocellated punctures as in Notaphus ; eyes very large and prominent ; palpi bronzed with the second joint obscurely rufous ; antennz longer than the prothorax, with the scape, and the base of the second and third joints, rufous: prothorax short, depressed both at the base and apex, the depressed part being wrinkled longitudinally ; dorsal channel and basilar impressions rather deep, in the latter are two little furrows: in the elytra, a little beyond the middle, in the interstice between the second and third furrows, are two quadrangular, oblong, slightly de- pressed spaces of a somewhat golden lustre, and marked at the anterior end with a punctiform impression ; immediately before, between, and after the depressed spaces, is a levigated and rather elevated one of the same shape; the furrows of the elytra are arranged nearly in the same way as those of Notaphus intermedius above described: the legs are rufous with the thighs bronzed at the apex. (ec) Fiviparria. Family ELAPHRIDAL. Elaphridans. XXIX. * Genus OPISTHIUS. Oral organs scarcely different from those of Elaphrus. Body depressed and flat. Head triangular, antennae much more slender and longer than those of Elaphrus, third joint rather longer than the fourth. Prothorax very short, transverse, scarcely wider than the head; anteriorly obsoletely obtusangular, posteriorly subrepand, depressed a little at base and apex; channelled, but without basilar impressions ; sides gibbous ; angles all obtuse. Scutedlum rather obtusangular. Elytra, alitrunk,8 and abdomen very much dilated, nearly twice the width of the prothorax, without furrows, with several rows of obsolete mammillated impressions. Legs rather longer and more slender than those of Elaphrus ; the hands of the male have the four first joints a little dilated and furnished underneath with a brush. This appears to be one of those transition genera which Mr. W. S. Mac Leay has denominated osculant, and to unite the Hygradephaga filipalpia with the subulipalpia, and more particularly Elaphrus with Bembidium. From the latter it borrows its general aspect, its short prothorax, its dilated elytra, alitrunk and abdomen; its oral organs, its head, and in some respects its elytra, and its legs are those of the former; its antenne resemble those of Cicindela; and the hand of the male has four dilated joints furnished with a brush as in the Carabide. The alitrunk is that part of the trunk which bears the wings and the four posterior legs. ELAPHRID. 61 (87) 1. * Opisrurus Ricuarpsoni. Richardson's Opisthius. O.

DESCRIPTION. Body with the gloss obscured; underneath black, somewhat hairy, above a little bronzed. An- tenne nearly half the length of the body, four first joints greenish-bronzed, the rest deep blue: front with a slight impression between the antenne and a few scattered short whitish hairs: protho- rax very short, more bronzed, transversely very minutely wrinkled: elytra with three rows of oblong greenish very slight impressions, each with a central oblong elevation, with another levigated one between each; adjoining the lateral margin is a fourth series of greenish-bronzed more numerous impressions without any central or intermediate elevations: thighs green-bronzed, tibie obscurely rufous, tarsi black, legs hairy.

Amer. Trans. ii, 80? PLATE I, FIG. 8. Length of the body 4 lines. A single specimen taken in the journey from New York to Cumberland-house. 62 NORTHERN ZOOLOGY. DESCRIPTION. Body glossy; underneath green-bronzed; above black slightly bronzed, covered with minute scattered, gilded punctures. Mandibles and palpi piceous; antennz black, with the three first joints dark blue; front with an elevation between the eyes, rather deeply impressed in the centre: pro- thorax longer than wide, uneven, with two large discoidal elevations separated by a dorsal channel, each with a central impression; a single basilar impression at the posterior angles tinted with blue: elytra with four irregular rows containing in all twenty-one slight circular impressions punctured, and tinted with blue, each, except the marginal ones surrounded by an elevated ring, and placed in a wider impression; between each of these impressions in the two first rows is an elevated and levi- gated space: thighs glossy-green, the posterior pair rufous at the base; tibiz and tarsi piceous. I am doubtful whether this species may not be Mr. Say’s . riparius, but it is not the real one, from which, and L. uliginosus, it is distinguished by being much less thickly dusted with green- gold glittering punctures, which gives it a blacker hue. The impression also in the elevated space between the eyes is much deeper. The blue-tinctured impressions of the elytra are also more distinct, and surrounded by a more elevated ring. It may be here observed that the peculiar sculpture which is so conspicuous in the elytra of Elaphrus may be first traced in those of Bembidium impressum which exhibits two gilded impres- sions; in Opisthius these impressions become more numerous, and assume a seriatim arrangement ; and in the genus first named they become more perfect and prominent—this affords a further proof of the affinity of the Bembidiadans and Elaphridans.

Intermediate Elaphrus, very minutely and thickly punctured; underneath green-bronzed, above black-bronzed ; tibie rufous; elytra with four rows of slight impressions with an eminence in the centre, and an elevated levigated discoidal space common to both elytra. Length of the body 4 lines. Taken by Dr. Bigsby in Canada. DESCRIPTION. This species resembles H. cupreus, but it is quite distinct. The body is more thickly and minutely punctured on the whole upper surface; underneath it is of a fine bronzed-green; above it is blacker and less brilliant: the head is greenish; the middle space between the eyes is less ele- vated than in that species, and wrinkled longitudinally without any impression: the impressions on the discoidal elevations of the prothorax are fainter: the elytra like the other species have a qua- druple series of impressions, but they are broader, more slight, without any elevated ring, are more minutely punctured, have a slight elevation in the centre, and are of the same colour with the rest of the elytrum; the marginal series is nearly obsolete ; just before the middle, adjoining the suture is a quadrangular elevation which unites with that of the other elytrum: the thighs are green, rufous at the base, tibie rufous, tarsi piceous. if >> ELAPHRID2. 63 (90) 3. * Evapurus opscurior.

Obscurer Elaphrus, above obscurely cupreous, head and prothorax thickly and minutely punctured ; elytra very slightly impressed, with four polished elevations. Length of the body 33 lines. A single specimen taken in Lat. 65°. DESCRIPTION. This species is more strongly marked than the majority of the Hlaphri. On the underside the head and trunk are copper with a slight tint of green; the abdomen of a dusky purplish cop- per: above it is copper-coloured; the head, with the exception of the upper-lip, is very thickly and confluently punctured, with a levigated but scarcely elevated space between the eyes; the four first joints of the antennz are cupreous: prothorax not wider than the head, confluently and thickly punctured ; discoidal elevations not conspicuous nor impressed; elytra not glossy, punctured with scattered punctures, marked by a quadruple series of very slight impressions, some nearly obsolete, most of them marked out by a very slight elevated ring and a circle of punctures, three levigated quadrangular spaces near the suture and arranged in a line parallel with it, and a fourth triangular one removed from it, near the apex; the disk of the elytra is faintly purple: legs bronzed.

Head with seven furrows between the eyes, the two lateral ones the deepest; nose anteriorly wrinkled longitudinally, behind with a pair of transverse punctiform impressions with a minute rather sharp elevation between them; antenne short, obscurately rufous at the base: prothorax punctured with the disk transversely smooth ; dorsal channel abbreviated; basilar impressions single, large: elytra punctured in rows, the interstice between the sutural and the second rows thrice the width of the other interstices: there are nine rows of punctures, the fourth, fifth, and six are also furrowed; the seventh, eighth, and ninth ter- minate in furrows, which run to the end of the elytrum, the two exterior ones becoming confluent : between the third and fourth rows in the anterior half of the elytrum is a deep punctiform impres- sion, and another very minute one with a central elevation is discoverable between the apex and the little furrow in which the fifth and sixth rows after they become confluent terminate: thighs a little bronzed. Family OMOPHRONIDZE. Omophronidans. This family, as far as at present known, consists only of a single genus, which appears separated by a very wide interval from the other insects of the present sec- tion, and makes a near approach to those Hydradephaga, or aquatie predaceous beetles that have no scutellum, as Haliplus and Hydroporus, with which, indeed, Clairville has associated it; and it agrees with them not only in having no appa- _rent scutellum, a character scarcely to be found, that I am aware, in any true Gea- dephagous genus ;° but its larva also, as appears from M. Desmaret’s description of it, though it wants the suctorious mandibles, exhibits a striking resemblance to that of Dytiscus. In fact, as far as our present knowledge leads us, its cognate forms are all in that tribe, none at present discovered among the terrestrial preda- ceous beetles coming near it. Future discoveries will probably help to fill up the hiatus between them; at present, however, it must be regarded as nearer to the Hydradephaga than the Geadephaga. I shall therefore consider it as occulant between them. 9 Mr. W. 8S. Mac Leay (Annulos. Javan. i, 23, 41, t. i, f. 4) has described an insect, which he places amongst his Har- palide, under the name of Anaulacus sericipennis, and whicb he regards as an anomaly, that has no apparent scutellum, which in this circumstance and in its shape seems to resemble Omophron, but as yet I have not had an opportunity of examining the insect. .

Length of the body 3} lines. Taken by Dr. Bigsby in Canada. DESCRIPTION. This species seems intermediate between O. limbatum and O. labiatum. From the former it differs in having a much fainter tint of green on the darker parts of the body; in its black protho- rax with silvery sides as well as margin. From the latter in having the lateral furrows as deep and distinctly punctured as those of the disk; and, instead of two reddish spots near the base of the elytra, having two angulato-undulated bands, one near the base and the other beyond the middle, and the tips, testaceous; all connected by the margin of the same colour. It seems to have escaped the describers of O. limbatum that the upper-lip and lateral margin of the prothorax and elytra are likewise silvery, though not so conspicuously as in O. labiatum and Sait. The sculpture of the elytra in this genus, as well as in Calosoma, differs from that of the other terrestrial predaceous beetles in having more than nine furrows, which appears to be the typical number in the section. iii.

[I have added a query to the synonym of Latreille, because, though his descrip- tion agrees with our insect, his figure does not, for it represents the elytra with eight black spots, which are not to be found in H. impressus. Mr. Stephens, in his description, does not mention that the punctures forming the rows on the elytra are black, which in a describer usually so accurate, renders his synonym somewhat doubtful. DESCRIPTION. Body reddish-yellow. Head punctured, dusky behind: prothorax yellow, depressed in the mid- dle posteriorly, with a transverse curved series of punctures in the depression; anteriorly there are five or six black dots arranged transversely ; at the base, between the central point and the margin on each side, an oblique little furrow but not easily discoverable, is impressed: elytra pale-yellow with a cinereous tint, nine rows of black punctures on each, those near the lateral margin being the faintest ; anteriorly, in the interstices of the rows, there are also a few black punctures; the apex of the elytra is oblique terminating in an acute point: the lamine that cover the posterior legs are punctured.

Body lurid-yellow, somewhat glossy, minutely and thickly punctured. Antenne dusky at the tip: prothorax with a minute black rhomboidal spot in the disk, which is marked with a punctiform impression; anteriorly it has a transverse series of punctures larger than those of the rest of its surface: elytra most numerously and minutely punctured; the suture, and four longitudinal stripes not reaching the apex, nor the first and third the base, all black; the fourth or outermost is distant from the margin and interrupted: the alitrunk and abdomen are black. In the female, which is less glossy, the external stripe is continuous, and only the second reaches the base; and in the male the prothorax is more conspicuously punctured, and the anterior series of punctures is wanting.

( Smooth Hydroporus, very smooth, black underneath, above lurid; prothorax transversely impressed behind: with two spots, elytra with six lines and three lateral spots, all black. ’ Length of the body 2 lines. One specimen only taken. DESCRIPTION. Vety like the preceding species but smaller; it differs principally in being perfectly smooth and without punctures, even when examined under a powerful magnifier. The head has two larger vertical lurid-yellow spots, and there is a triangle of the same colour between the eyes, which at its base is dilated and occupies the nose and mouth: the prothorax is lurid-yellow, with two oblong oblique dusky spots beyond the middle; towards the base is an obtusangular transverse impression, and on each side, at a little distance from the margin, is an oblong punctiform impression; in the elytra are six distinct narrow black stripes, none of which are confluent except at the apex; at the side, but at some distance from the lateral margin, are three black spots placed in a line, or a stripe wider than the others twice interrupted: the legs are testaccous with the posterior tibia black at the tip.

Length of the body 23 lines. Taken with the preceding species ? DESCRIPTION. I at first regarded this as the other sex of HZ. picatus, but upon inspecting their tarsi I found they were both males. ‘This species is smaller, more glossy, the parts that in that are dark ferru- ginous, in this are much paler; the punctures on the upper surface are less numerous and larger, especially those of the basilar half of the elytra, and the four furrows, particularly the three dorsal ones, are deeper and more distinct; the disk of the prothorax also is transversely levigated and impunctured. Both these insects come very near to H. picipes, but that species has not the discoidal impression in the prothorax; and its elytra are dark testaceous, striped with black. N. B. All the above species belong to Mr. Stephen’s second division of the family with the sides of the prothorax rounded. HALIPLIDA.—DYTISCID~. 69 XXXV. Genus LACCOPHILUS. Leach.

Body oval, black, above slightly bronzed, not glossy, covered above and below like the preceding species, as it were, with a web of net-work; but the reticulations are more minute. Upper-lip, palpi, and antennz ferruginous; a pair of oval, minute, obscure, red spots mark the vertex: protho- rax with the anterior transverse series of punctures double in the middle, the posterior one not easily discernible, discontinuous in the middle: there appear no rows of punctures on the elytra, but a few scattered ones may be discovered: the four anterior legs are piceous. This species approaches C. chalconatus, but it is longer, less glossy, the reticulations of the surface are more distinct, no rows of punctures are discoverable, as in that, on the elytra, which as well as the prothorax are all of one colour; and the posterior legs are black. It seems still nearer C. ater, but it is much smaller, less convex, and has no fenestrated spot on the elytra. (106) 7. CotymBetes assimiLis. Similar Colymbetes. C.

Length of the body 53 lines. Taken in Nova Scotia by Dr. Mac Culloch. DESCRIPTION. Body rather depressed, between oblong and obovate, smooth, rather glossy, black, covered above with an infinity of very minute reticulations. Head dirty-yellow ; vertex black, with a pair of con- fluent transverse reddish spots: prothorax dirty-yellow, rather dusky in the disk, transverse, punc- tures nearly obliterated : elytra of the same colour as the prothorax, but sprinkled with innumerable black dots, which however do not extend to the base and sides; a row of more distant and larger dots adjoins the suture : the fore-breast, the base and apex of the other ventral segments of the abdomen, are dirty-yellow; the legs are of the same colour, but the arms are shorter than usual and piceous; the dilated posterior coxe are sculptured with branching rugosities. This species represents C. notatus, which it is very like, but the elytra are wider towards the apex which gives the insect an obovate shape; the black dots of the elytra are more numerous, and minute; the prothorax is without spots : and the arms or fore-legs are shorter and of a different colour. ee een DYTISCIDZ. 73 (107) 8. * CoLYMBETES TRI-sERIATUS.

Length of the body 73 lines. A single specimen taken. I have a specimen also from New England, taken by Professor Peck. DESCRIPTION. Body elliptical, rather depressed, underneath black, and covered with an infinity of branching or confluent wrinkles, as if scratched by a pin or needle. Head black, anteriorly testaceous, between the eyes is a pair of transverse red spots; antenne and palpi testaceous, dusky at the tips: prothorax testaceous with an abbreviated, subbilobed, discoidal band; variously acuducted so as somewhat to resemble net-work: scutellum ferruginous, black at the base, very minutely and confluently punctured: elytra dusky, which colour, for they are really lurid or dirty-yellow, is produced by an infinity of transverse black lines or furrows, but which at the lateral margin lose their blackness; besides these there are three rows of punctures arranged longitudinally but not regularly, the first adjoining the suture, and the two others being discoidal; between the outer one and the margin, especially near the apex, are some scattered punctures; the epipleura, and sides of the fore-breast, are yellow: legs testaceous ; thighs and tibie punctured. This species is intermediate betwen C. striatus and C. dolabratus, with the former it agrees in the majority of its characters, particularly in the longitudinal rows of punctures, except that its sutural one is more perfect ; and with the latter in the prothoracic band, and the colour of the legs. The transverse furrows of the elytra are rather deeper than those of the first-mentioned species, and not so deep as those of the last. These insects, adding C. Suscus, may perhaps be regarded as forming a subgenus, whose common character is the peculiar sculpture of the elytra. y. Subgenus Hypaticus. Leach. (108) 1. * CotymBeres (Hydaticus) rucicoiuis.

DYTISCID. 5) DESCRIPTION. of Body reddish-yellow underneath, above olive-black. Head minutely but thinly punctured ; mouth, nose, and antenne yellow; there is a red angular spot on the vertex: prothorax obsoletely channelled, minutely and thinly punctured, with the limb widely yellow, but less so behind where the yellow sends two teeth into the black disk; an anterior and posterior transverse line of larger punctures are also visible: scutellum wholly black: elytra with two discoidal longitudinal rows of punctures; three others, in which the punctures are more distant and less conspicuous, are interposed, one between the suture and the first row, the next between the first and the second, and the third between the second and the lateral margin ; there are besides a few scattered and very minute punctures; at the apex these rows are all lost in a number of scattered punctures intermixed with punctiform impres- sions; the side of the elytra, the external half of their base, and an oblique gleam at the apex are all yellow, which colour though occupying a considerable breadth of the side, at the base and apex is a narrow strip:> the sutures of the breast and margins of the ventral segments of the abdomen are black or dusky ; scapulars rather thickly, deeply, and confluently punctured; lateral angles of the mesostethium wrinkled; posterior dilated; coxe thinly punctured, legs yellow; the lobes of the metasternum are acuminated as in D. circumflexus.4 ? The female differs from the male, in having the yellow parts redder, especially on the under-side of the body; the head and the prothorax are more thickly and distinctly punctured; the angular red signature of the vertex reaches the red spot between the eyes and the nose; the elytra are ploughed out into ten deep furrows, the external ones being the widest, there is also a very short one between the sixth and seventh at the base; these furrows approach the end of the elytrum, and most of them terminate in a series of punctiform impressions which nearly reach the tip; the eighth and ninth furrows are shorter than the rest, and included between the confluent ends of the seventh and tenth; the whole elytrum is thickly and visibly punctured; the scutellum is piceous: the mesostethium is black with a large anterior yellow spot; the sutures and the margin of the seg- ments are more widely and distinctly black than in the male. I at first regarded this as a variety of D. marginalis, and it is probably the species to which Linné refers as found in North America: but upon a close examination I am convinced that D. Ooligbukii, though the representative of that species, is not synonymous with it. The lobes of the ' metasternum which terminate in a long acumen like those of D. circumflexus sufficiently prove this; _the prothorax of the male is shorter and more distinctly punctured, and the elytra less so. The female has a little furrow between the sixth and seventh, not in D. marginalis ; the furrows are all parallel, and fall short of the apex one third of the length of the elytrum—other more minute differences are also observable. As this species was taken by the useful, worthy, and honest Esquimaux Ooligbuk, I trust I may be excused for giving to it his name. 3 If the elytra are rubbed hard, the black colour comes off and leaves the yellow. 4 Curtis, Brit.

Head smooth; nose, upper- lip, and palpi, reddish-yellow ; the latter with the last joint dusky; between the eyes is an obscure, roundish, red spot: prothorax smooth except an anterior transverse series of punctures which does not reach the sides; as in the preceding species it is surrounded by a broad reddish-yellow margin: sculpture of the elytra like that of D. Ooligbukii, &c. but not so grossly punctured at the apex; side reddish-yellow, the yellow stripe terminating in a fork or two branches, the upper one not consist- ing of dots as in D. marginalis, &c. but entire a toothed: a reddish-yellow arch marks the dilated posterior coxe, and the base of the abdomen is of the same colour; arms and thighs, pale chestnut, tibie and tarsi of the four posterior legs black: the lobes of the metasternum are remarkably obtuse. I have named this insect after a very eminent American Entomologist, Dr. 'T. W. Harris, who well merits such distinction. vi. * Subgenus Lrionotus. Elytra foeminea haud sulcata. Several species of Dytiscus being already known, distinguished from the typical group by the females having elytra without furrows, and as smooth as those of the male, as, for instance, D. conformis, circumcinctus, &c.° it is evident that they form a distinct group, and of that kind now denominated a subgenus. 5 See Gyll.

Head with a very few minute, scarcely discernible, punctures ; antenne chestnut; mandibles and palpi black; nose, upper- lip, margins of the prothorax, and side of the elytra, dusky yellow: prothorax distinctly channelled, surrounded within the margin with an irregular series of punctures, interrupted at all the angles, and in the middle anteriorly and posteriorly: elytra sculptured as in the two preceding species, except that there are several very obsolete rows of flat granules scarcely discernible between the suture and the first row of punctures; and there is no yellow oblique band or gleam near the apex: legs black, with the arms and intermediate thighs dusky or dusky lurid; the lobes of the metas- ternum very acute, more than usually diverging, incurved a little at the apex. % Head more visibly, though still very minutely, punctured: prothorax minutely punctured : elytra more coarsely punctured at the apex: legs dusky lurid, posterior tibie darker, tarsi black; scapulars, and parapleure grossly punctured; angle of the mesostethium wrinkled ; posterior coxe lightly, but not thickly, punctured; lobes of the metasternum very acute, not incurved at the apex. This species a good deal resembles D. L. conformis, but it is larger, the legs are darker, the elytra do not exhibit traces of three or four obsolete flat ridges, but in the interstices between the suture, and the first and second rows of punctures, are several rows of obsolete, very minute, flat granules or tubercles not easily discernible except under a strong magnifier: the lobes also of the metasternum diverge more than in the species alluded to. 78 NORTHERN ZOOLOGY. b.

Antenne obliquely subtruncated at the apex. Body depressed, obovate; scutellum covered; elytra with nine obliterated furrows; arms shorter than the body. The genus whose characters are here given, and the type of which is Gyrinus Americanus, occupies an intermediate station between Dineutus Mac Leay® and Gyrinus. rom the former it differs in having a ciliated upper-lip, truncated antenne, and arms shorter than the body; and pro- bably in other characters not noticed in Mr. Mac Leay’s brief description and definition of the genus. It is distinguished from Gyrinus by its broad, depressed body; by the different shape of the last joint of its palpi, and by having no apparent upper lobe to its maxille:? it has likewise no visible scutellum, and the elytra have only nine obliterated furrows, whereas in most Gyrini there are eleven. The tongue (or labium of most modern authors®) is much shorter in Gyrinus with a pair of deep impressions. The genus here laid down appears to be widely dispersed as I have specimens belonging to it from India as well as from America. (113) 1. * Cyerinus assiminis. Similar Cyclinus. C.

Head a little bronzed; nose transversely impressed, wrinkled ; frontal impressions large and deep: prothorax with a deep anterior transverse impression, reaching nearly from side to side, in the centre of which is also a deep punctiform impression, and behind it on each side two others, but wrinkled and more shallow ; on each side also is a large gibbosity or boss: elytra nearly oblong, with eleven rows of shining bronzed punc- tures; at their apex the punctures are scattered, the margins also are bronzed; epipleura black ; the tip of the elytra is very obtuse and almost truncated: legs rufous. This species is very near G. marinus, but it is much larger, and is sufficiently distinguished from it by the deep furrow or channel that runs quite across the prothorax, its more prominent bosses, and its impressions. In G. marinus, also the punctures at the tip of the elytra are not scattered, but mark out a crescent-shaped area, and the apex itself is not so obtuse. 80 NORTHERN ZOOLOGY. (115) 2. Gyrinus #NEus.

BRACHELYTRA. Cuy. Having described the insects included in my plan belonging to the first great Coleopterous group, or section, both terrestrial, intermediate, and aquatic, I must now turn my attention to the next, but which ought to be regarded as such, is a question not yet fully decided; since different Entomologists, and those of the first eminence, having quitted the Adephaga, or predaceous beetles, distinguished by the upper-lobe of their maxille being palpiform, have pursued different routes. M. Latreille places next to the aquatic Adephaga the Brachelytra of Cuvier, con- sisting of the great Linnean genus Staphylinus; while Mr. W. S. Mac Leay takes next the remainder of the aquatic beetles, as forming one great group, which he denominates Philhydrida.! This gentleman seems to wonder that so acute an Entomologist as M. Latreille should not perceive an affinity which almost all other investigators of insects have acknowledged:? the last mentioned author, however, in his most recent work, per- haps with a view to this objection, has assigned his reasons for this opinion, and they seem not devoid of weight. “The anatomy,” he observes, “ of these insects, differs essentially. ‘The alimentary canal of the Hydrophili, has considerable an- alogy by its length, surpassing four or five times that of the body, and by its texture, with that of the Lamellicorns (Scarabeus L.) and approaches that of the ddephaga only with regard to its biliary vessels. ‘They have neither the natatory vesicle, nor the excrementitial apparatus which characterizes the Dytiscide. In the ,females that apparatus is replaced by organs secreting the matter that forms her egg-cocoon. Finally, the male genital organs have the closest affinity with those of the preced- ing family :’’—viz. the Clavicornes including the Silphide, &c. M. L. Dufour also observes, that this structure of the male genital organs, justifies M. Latreille in placing his Palpicornes (Hydrophilus, &c.) where he does.* If we further compare the oral organs of Hydrophilus with those of Dytiscus, we shall find a striking difference. The mandibles are not precisely like those of any other genus, but in one respect they resemble those of many Lamellicorns; at the base, on the inner side, they are furnished with a large molary space or plate,° but not striated. They are evidently fitted for strong work; at the apex is a stout - 1 Annulos. Javan. 6. 2 Ibid, 32. 3 Latr. Crust. Arachn. et Ins. i, 519. * Ibid. note 1. > Linn. Trans. xiv, 105.

BRACHELYTRA. 83 somewhat conical tooth, rather obtuse with a lateral prominence; then follow three flat rather distant teeth emarginate at the apex, which appear to act as incisives, intermixing somewhat of a molary structure; and next succeeds the molary plate: now this is as dissimilar as possible to the toothless mandible of a Dytiscus.6 The maxillee are equally dissimilar,’ those of Hydrophilus approaching those of a Silpha, except that the spine on the lower lobe is truncated, and terminates in two ungui- form bristles. The lower-lip and the tongue also exhibit no resemblance.® The affinity, therefore, of Dytiscus and Hydrophilus, cannot be proved by those characters, which are usually and properly regarded as the most essential indica- tions of it; and recourse must be had to characters that have been judged less important, such as their being cohabitants of the same element, exhibiting a strik- ing resemblance in their general aspect and form, and in their external parts and organs: and here I must candidly own, that, with the exception of the antenne, and the hands of the male, the resemblance is most striking, and can scarcely be the effect of any thing, for analogy seldom extends to so many points of agreement, but a near approach to each other. It may be further argued, that some insects of the tribe make a nearer approach in their more essential characters than Hydrophilus itself—this appears to be the case with Spercheus, with respect to the palpiform or upper lobe of its maxille,9 Parnus in its mandibles,! &c. and future observers may make further discoveries. The above observations, however, prove that M. Latreille was not led by mere system to doubt the connection of the two groups in question. His greatest error, as it seems to me, was that of placing his Serricornes (Buprestis, Elater, &c.) be- fore his Clavicornes and Palpicornes, which clearly have no business there, since they separate tribes that ought not to be disunited. To me the last-named tribe, or Philhydride of Mr. Mac Leay, appears to bear the same relation to the Hydra- dephaga, that the former, or Necrophaga of the same author, do to the Geadephaga, but there seems to be an osculant group necessary to connect the latter, which ap- pears not wanted in the former. The group to which I allude is the Brachelytra, or Staphylinus of Linné: and these M. Latreille, though they connect at least in two points with the Geadephaga, and scarcely in any with the Hydradephaga, has placed after the latter: nor could he do otherwise in a linear arrangement, without breaking up the great and natural group of the ddephaga; unless indeed he had ®° Compare Curtis Brit.

M 2 84 NORTHERN ZOOLOGY. followed Mr. Mac Leay’s arrangement, which places the Brachelytra at the end of his circle of Chilopodimorpha: but as he does not connect it with the point from which he at first sets out, nor indeed with any of his Cicindelide, it seems to fall short of his system. Connected as it is, as I shall presently shew, with the Gea- dephaga and Necrophaga of Mac Leay, on each side by more than one link, even this would not lead to a natural arrangement. We see then, as in the former instance, that both these gentlemen, according to their different views, were correct, and followed nature; Mr. Mac Leay, in placing the Philhydrida next to the Hydradephaga, and M. Latreille,in placing the Bra- chelytra next to the Adephaga in general. I shall now assign the reasons which induce me to prefer M. Latreille’s arrangement. Scarcely any tribe of insects seems to be found in such various situations and in such different substances as the one in question. Some are found in dry and sandy spots; others in humid ones; some under stones; others in chalk ; some under bark; others in the wounds of trees where the sap exudes; some on the shore of the sea, or of estuaries under the sea-weed ; others under or in decaying vegetable substances ; some again in flowers; many in the various kinds of fungi; the ma- jority perhaps in cow-dung; and several, lastly, in dead flesh and the carcases of animals. But though their range is thus nearly universal, and the substances they frequent are so various, are we from hence to conclude that these substances are their appropriate food, or may we not rather infer that their principal object in fre- quenting most of them is to devour the larve of other insects that are bred there ? Olivier and Latreille appear both to have been of this opinion ;? and if we examine the insects themselves we shall find characters, in the majority of them, that indi- cate a predaceous character. ‘Their very aspect, at least that of many, excites the idea of a ferocious animal ; especially when they move with their threatening jaws expanded, and their abdomen turned over their back, like the scorpion when pre- paring to strike. ‘These jaws also, or mandibles, much resemble those of the Adephaga, and are of a laniary description, which could only be useful to predatory animals, to enable them to seize and lacerate their prey; they usually also cross each other at the tip like the tribe just named, especially the Cicindelide. The maxille too of the generality have the upper lobe palpiform and _biarticulate,* though not so slender as in the Adephaga. Their alimentary canal, as appears both from Ramdhor and L. Dufour,’ does not essentially differ from that of the "2 Oliv. Ins. iii, No. 42,3. Latr. N. D. D’H. N. xxxii, 116. 3 Grav. Micr.

BRACHELYTRA. 85 tribe just named. It must not, however, be forgotten, that predaceous animals will sometimes content themselves with vegetable diet, and vice versa herbivorous ones will sometimes attack animal matter. Cats will eat bread; I have seen, more than once, Harpalide devouring the seeds of umbelliferous plants; Silpha 4-punc- tata, Mr. Mac Leay informs us, ascends the oak for the purpose of devouring caterpillars: the same learned Entomologist remarks, with respect to carnivorous Coleoptera, “that as the aberrant insects of any group leave the living animal food, which forms the entire subsistence of the normal part of the same group ; they prey on dead animal matter, or, in preference to other vegetable matter, on fungi,’ to which it may be further added, in preference to fresh vegetable matter, on putrid or putrescent—thus Creophilus, an aberrant Brachelytrous genus ap- proaching Si/pha, lives on dead flesh, and others, as Oxyporus, on fungi. From all the circumstances and characters above detailed, it seems evident, that, with the exceptions just stated, the Brachelytra may generally be looked upon as predaceous, therefore I regard their affinity to the Geadephaga as more intimate than that of the Philhydrida to the Hydradephaga. There are two points by which the group in question may enter that of the terrestrial Adephaga: one is that which Mr. Mac Leay has indicated, and which has been adopted in Mr. Stephens’ Systematic Catalogue, by Lesteva Lat. (Antho- phagus Gravenh.) which appears connected with those that have truncated elytra, as Lebia, &c.; and the other is by the Stenide, which exhibit as much of a Cicin- delidan port and aspect as the other does of a Carabidan. These appear to approach towards Colliuris, not only by their narrow bodies and clavated antenne, but likewise in having truncated elytra. Led by these considerations, I shall now proceed in the first place to the descrip- tion of the Brachelytra upon my list, as coming next the terrestrial 4dephaga, from which I shall proceed to the Necrophaga, or Clavicornes of M. Latreille’s _ last work, and from them to the Philhydrida, or Palpicornes of the latter author, as the group that connects with the aquatic ones, which will still maintain Mr. Mac Leay’s circular distribution though inverted. I must here observe, that, after Linné and Fabricius, Mr. Stephens, in the work lately quoted, has made the Brachelytra his last coleopterous group, thinking perhaps that their abbreviated elytra connects them with Forficula, and their anal styles, which sometimes, as in Dianous Leach, become sete, with Blatta: at the > Annulos.

Head obovate, minutely and thickly punctured; mandibles, palpi, and what remains of its mutilated antennz, dark chestnut: prothorax an oblong square with all the angles rounded; punctured, but not very thickly, with scarcely any smooth longitudinal space: elytra longer than the prothorax, thickly punctured, of a dark chestnut: legs mahogany, cubit armed with a short wide tooth or prominence on the inner side at the base, the four first joints of the hand are dilated, indicating probably that the specimen is a male. This appears to be the representative of ZL. dentatum F, which it nearly resembles, but the elytra are considerably longer, the colour of the legs is darker, and the humerus, or anterior thigh, is propor- tionally smaller and has no tooth. 1 (121) 3.* LarHrosrum GravenHorstiul.

Gravenhorst describes Knoch’s specimen, which also came from North America, as having dark chestnut thorax, elytra and anus; in the specimen here described they are of the same colour with the legs.

As this tribe includes genera that lead towards Mitidula, Catheretes, &c. on one side, as Micropeplus and Proteinus; and towards Lebia, &c. as Lesteva, on the other, I have given it a name indicative of that circumstance. The reader will here recollect that having described those Brachelytra that lead to Stenus, of which last there were none taken in the Expedition, and so connect- ing with one branch of the Geadephaga, I now go to the insects nearest to Lesteva, of which likewise there were no specimens, which lead to another.

The insect here described approaches very near to Corticaria impressa of Mr. Marsham (Ips impressa Oliv.)? but it is sufficiently distinguished not only by its colour but chiefly by the very visibly denticulated sides of its prothorax. I may here observe that most authors, probably on the authority of Latreille, have rejected the synonym of Olivier; his figure, however, appears to me clearly to denote Mr. Marsham’s insect, which was I believe first described by Herbst,8 under the name of Latridius gibbosus, and has no relation to Cryptophagus serratus, of which the first mentioned learned author seems to regard it as a variety. Family CRYPYVOPHAGIDZA. Cryptophagidans. LIX. * Genus ATOMARIA. Kirb. Steph. DESCRIPTION. Body elliptical. Antenne anteocular with the intermediate joints rather slender; scape much incrassated, the three terminal joints often gradually increasing in size, subturbinate, except the last which is obturbinate and very acute ; these three joints form a short club or knob; head subtrian- gular; eyes small, round, and convex: prothorax transverse, convex, subquadrangular with curved unarmed sides: scutellum transverse: elytra taken together ovate, very convex: legs short, rather’ slender ; tibiz curved; tarsi five-jointed ? claw-joint long; claws simple. This genus, consisting of very minute insects, differs from Cryptophagus, in having the legs and the stalk of the antenne much more slender; the prothorax and elytra viewed separately are more convex, and the former has a transverse basilar impression not observable in the latter, and its sides are always unarmed. ‘The extreme minuteness of all the species has prevented me from obtaining any clear idea of the parts of the mouth, so that I can only give the above as the distinctive charac- ters of the genus. ; Both Latreille and Gyllenhal consider Cryptophagus as a pentamerous genus, but it appears from Mr. Curtis’s figure and description of C. Populi that one sex is heteromerous.? Whether this is the case with Atomaria I have not been able to ascertain; all those individuals, however, that I have examined appear to have pentamerous posterior tarsi. 7 Marsh. Ent.

CRYPTOPHAGID-©=.—DERMESTID®. 113 DESCRIPTION. In shape, sculpture, and pubescence this species resembles the preceding, but it is smaller, and the whole insect is entirely of one colour—dark ferruginous. N. B. The two species last described differ from the other Cryptophagi in having the thorax without serratures or denticles, and the scutellum obtusangular, and may perhaps form a subgenus. It should seem to result from a comparison of Necrobia with Cryptophagus that there is an affinity between them; the former, as restricted by Mr. Stephens,! is a necrophagous genus: WV. Quadra, of which I was the first discoverer and sent to the late Mr. Marsham with that Trivial name, I found upon the bones of dead animals very busily engaged in devouring what remained upon them. If this idea prove correct, it will furnish another instance of a collateral departure from the main stem of the system in a different direction from that to which its more evident affinities conduct us.

A. /cylindricus) nigro-piceus, subcylindricus, cinereo-subpubescens ; antennis medio tarsisque rufis. Cylindrical attagenus, subcylindrical, dark-piceous with cinereous down: antenne, in the middle, and tarsi, rufous. PLATE VII, FIG, 3. Length of the body 2 lines. Two specimens taken in the Rocky Mountains. DESCRIPTION. This little species has much the air of a Cryptophagus, but belongs to the present genus. The body is subcylindrical, dark-piceous, very minutely punctured, and covered, but not thickly, with decumbent cinereous hairs. The two first joints of the antenne are large, globular, and of the same colour with the rest of the body; the intermediate ones very minute and pale rufous; the three last are incrassated and form an oblong piceous knob, of which the terminal joint is as long as the two preceding ones, ovate and acute: the prothorax behind is very obsoletely trilobed with ‘the in- termediate lobe rounded: the tarsi are rufous. 1 Systemat.

This species, though particularly destructive to furs, is to be met with in other animal matters, and is very common in houses. De Geer describes its larva as having a very long body covered with a hard shining skin of a reddish-brown colour and hairy; as having six legs, and the posterior extremity terminated by a long remarkable tail, formed of rufous hairs as long as the body, and placed horizontally in the same line: He says their motion is gliding, but by snatches. DESCRIPTION. The American specimen, which is a male, is considerably larger than my British ones and blacker; but in other respects it precisely resembles them. ‘The species may generally be known by its black or dark-piceous colour, covered, especially underneath, with decumbent whitish or cinereous hairs. The stalk of the antenne, and the tarsi, are testaceous, and the last joint of the former, in the male, is longer than the two first and cylindrical : the prothorax at the three posterior angles has three white spots formed of hairs, and the elytra one in the middle near the suture.

Mandib. iii, 121, 1. Length of the body 43 lines. Taken in Nova Scotia by Capt. Hall; in Massachusets by Mr. Drake. Latreille observes that this insect is found in every quarter of the old world, and the specimens from which the following description is taken, furnish a proof that it is also a devourer of hams and bacon in the new. ‘These, however, could not have been its original food, since it must have existed before hams and bacon were invented: in fact, though often found in them, it feeds indiscriminately on all animal substances, whether putrescent or dried. DESCRIPTION. The American specimens differ in no respect from our English ones. ‘The body is black, covered more or less with decumbent cinereous hairs. It may always be known by the fusco-cine- reous base of the elytra with three black dots placed in a triangle. (164) 2. * DeRMESTES DISSECTOR. Dissector Dermestes. D.

Dissector Dermestes, black, pubescent ; antenne mahogany-colour, legs piceous, head and prothorax clouded with brown and cinerequs, elytra with cinereous only. Length of the body 33 lines. Taken by Dr. Bigsby in Canada. 116 NORTHERN ZOOLOGY. DESCRIPTION. This species appears to be the American representative of D. murinus, from which it differs principally in having the upper-side of the body less conspicuously mottled with whitish hairs, and with having brown ones intermixed with those of the head and prothorax: the antenna also and palpi are of a dull mahogany colour, which in the last species are black, and the knob of the former is considerably narrower ; underneath also the hairs on D. Dissector are not so densely planted as in D. murinus, and are finer, and of a purer white. Family BYRRHIDAE. Byrrhidans. LXIIJ. Genus BYRRHUS. Linn. precces pie (165) 1. * Byrruus picires.) Pitch-legged Byrrhus. B. ( picipes ) niger, pube obscurus, elytris vittis tribus obsoletis interruptis, fasciaque postica abbreviata, holosericeis atris ; pedibus piceis. Pitch-legged Byrrhus, black, gloss obscured by hairs, elytra with three obsolete interrupted stripes, and a posterior abbre- viated band, of a deep velvet-black ; legs piceous. Length of the body 3t lines. A single specimen taken in Lat. 54°. DESCRIPTION. Body black, covered with short decumbent hairs. Scutellum velvetty-black: elytra with a pair of deep black interrupted stripes terminating in a transverse abbreviated posterior band of the same colour: legs piceous. The insects of this genus are, most of them, so extremely alike in shape and sculpture, differing principally, like the Humble-bees,? in size and the colour of the pubescence that covers them, that it is difficult to say whether any individual is entitled to rank as a species, or ought only to be con- sidered as a variety. ‘That here described seems to claim a distinct name as well as most, since it not only differs from the subsequent one in the colour of its pubescence, but likewise in that of its | legs. I at first considered it as B. ater, but it does not agree with the general descriptions of that insect. 2 Kirb. Mon. Ap. Angi. i, 207. BYRRHID. 117 (166) 2.* Byrruus concotor. Concolorate Byrrhus. B. (concolor) niger, pube obscurus, prothorace distincte canaliculato ; elytris vittis tribus interruptis obsoletis holosericeis atris. Concolorate Byrrhus, black, gloss obscured by pubescence ; prothorax distinctly channelled: elytra with three obsolete interrupted velvetty deep black stripes. Length of the body 3 lines. Two specimens taken in Lat. 54°. DESCRIPTION. This nearly resembles B. picipes, but it is much smaller, the prothorax is more distinctly chan- nelled, the elytra have no black band, and the legs are black. We have a variety? of this species in Britain, rather larger and not quite so black, with the prothoracic channel less distinct, which Mr. Stephens seems to regard as a variety of B. pilula,3 but it is only three-fourths of the size of that species, rather wider in proportion to its length, and its pubescence is of a different colour. ‘The only thing in which they agree is in having three inter- rupted velvetty stripes on the elytra, but in B. pilula the first is more distant from the suture than in B. concolor. (167) 3. * Byrruus cycLopHorus. Circle-bearing Byrrhus. B. (cyclophorus ) ferrugineus, supra niger, pube obscurus, coleoptris circulo pallido subinterrupto inscriptis. Circle-bearing Byrrhus, ferruginous, above black, gloss obscured by pubescence ; coleoptra inscribed with a pale subinter- rupted circle. Length of the body 32 lines. One specimen only taken. DESCRIPTION. Body underneath and limbs dull ferruginous, above black with some cinereous hairs intermixed. Antenne piceous: elytra with two deep black subinterrupted stripes, and inscribed in the middle with traces of a circle formed of pale, or cinereous hairs, common to both. The circle is probably more distinct in recent specimens. 3 Steph. Cat. 98, 1029, i, 6, 118 NORTHERN ZOOLOGY. (168) 4. Byrruus varius. (Fabricius.) Varied Byrrhus. Byrrhus varius. Fab. Syst.

The European specimens have not the patch of golden hairs above the scutellum: in other respects they are precisely the same. Taking our departure from the Geadephaga, or terrestrial branch of the Preda- ceous, we have at length arrived at the confines of the Lamellicorn, Beetles; but before we proceed to the consideration of them, we must revert to the aquatic branch, and the tribes, connected with it, that tend also to the same point: and here, as our former route, if I may so speak, was by land; so now we must chiefly travel by water, since the Philhydrida of Mr. Mac Leay, which we are next to describe, are mostly inhabitants of that element: or at least abound in very humid situations: but our voyage will not be long, since only three specimens belonging to one genus of these tribes were collected in the Expedition.

HISTERIDZA. 2 121 DESCRIPTION. Body subelliptical, minutely punctured; underneath black somewhat hairy with very short incon- spicuous hairs, above lurid or dirty-yellow, glossy, more conspicuously punctured. Head black with a quadrangular yellow spot before each eye; nose gibbous, separated from the front by a transverse angular line; palpi and antenne dirty-yellow, the latter with a black knob: prothorax with a dark, discoidal, subquadrangular spot, which does not reach the anterior margin: elytra with a furrow adjoining the suture; shoulders with a dusky line: tibia and tarsi dusky rufous. Variety B. Larger, dusky rufous above, spots before the eyes larger and subtriangular: black spot on the prothorax wider but not so near the anterior margin; shoulders of the elytra without a dusky line. The American specimens have no black spots contiguous to the discoidal one on the prothorax, noticed by Major Gyllenhal and Mr. Stephens. Variety B. is very like Variety y. of Stephens (Var. c. Gyllenh.) Hydrophilus dermestoides of Forster and Marsham, but the front is spotted. Most modern Entomologists seem agreed in placing the Spheridiade next to the Philhydrida, and the genera that connect them are clearly Hydrobius and Cer- cyon. The insects of this last genus indeed are generally terrestrial, but one species is strictly aquatic—I allude to Cercyon aquaticum,> which Fabricius has described under the name of Hydrophilus hemorrhoidalis,6 and which was sent me as such by Gyllenhal so long ago as 1802. Afterwards in his Insecta Suecica, he denominates it Spheridium hemorrhoum.’ ‘This family, as well as the Byrrhide, has considerable affinity with the Misterid@, to which it approaches by Abreus; so that the aquatic branch which leads from the predaceous beetles here again seems to meet the terrestrial, and which by means of the Histeride proceed, as it were, together to the Lamellicorn tribes: Mister of Linneus, therefore, seems rather an osculant group, than a part and portion of the great section last mentioned. 5 Step. Lllustr. Mandib. ii, 188, 6. 6 Ent. Syst. i, 185, 16. 7 i,107,9. Mr. Stephens’ Cercyon hemorrhoum ( Illustr. Mandib. ii, 143, 23) must therefore be a different species. Mr Stephens, both in his Catalogue (64, 658, 32) and in the work just quoted (145, 32,) has referred to my MS. Catalogue, for a name he has adopted; but the name is incorrectly written. Instead of Spheridium convexium, in my Catalogue it stands, as it should, as the neuter of converior, S. convexius. 122 \ NORTHERN ZOOLOGY. Family HISTERIDZE. HMisteridans. This family, though not numerous, presents to the scrutinizing Entomologist many different forms, which appear to lead many different ways. M. Latreille has observed with respect to it, that though, in many respects, the Histers seem to approach the coprophagous Lamellicorns, yet that other considerations founded upon their anatomy indicate a station near the Silphide,® which he says is likewise the opinion of M. L. Dufour: accordingly there are several forms in the family that appear to tend that way: thus Onthophilus exhibits some of the peculiar characters of Micropeplus, one of the Nitidulide; Spherites, one of the last- named family,? but of a different general aspect, was long regarded as a Hister ; and in the typical form, or true Histers may be traced many characters which are also to be found in Necrophorus. But still I am of opinion that the Misterid@ are the steppingstone, as I have before observed, on the one side from the MNecro- phaga and on the other from the Philhydrida to the Lamellicorn tribes, but that they diverge into two branches, one leading to the coprophagous Lamellicorns, and the other to the lignivorous ones, or stag-beetles. Mr. Mac Leay, as I lately hinted, has associated the tribe we are considering, with the latter portion of the Lamellicorn beetles, forming a separate secondary group of them under the denomination of Rectocera, which he has further subdivided into two circles or columns, which, from the supposed nature of their food, he distin- guishes by the appellations Saprophagous and Thalerophagous, or devourers of putrescent and nonprutescent substances: the former consisting of the HMisteride, and the latter of the Lucanide. But is there really this distinction between them? The former group, besides dung, which is their more general pabulum, feed also upon animal matter, upon fungi, and upon decaying timber, and many upon the sap exuding from the wounds of trees ; the latter, in their feeding state, are gene- rally found in putrescent wood, and therefore are saprophagous; what they feed upon in their perfect state appears not to have been clearly ascertained, and their oral organs scarcely afford a certain indication of the nature of their food. If they are found to feed upon the exuding sap of trees, this is hardly sufficient to dis- tinguish them from the Histers, which very often do the same. It seems to me, therefore, that I best follow the guidance of nature, when I consider the Histeridce 8 Crust. Arachn. et Ins. i, 491. ¥ Gyll. Ins. Suec. i, 241, 31. Se ee ee ee HISTERID.&. 123 as forming an osculant group between the Lamellicornia, and the Necrophaga and Philhydrida, rather than as belonging to the former, and likewise when I regard the coprophagous Histers as connected with the coprophagous, and the lignivorous ones with the lignivorous, Lamellicorns: so that they appear to diverge towards the two extremities of that vast primary group; for that the Lucanide are most intimately connected not only with Trogosita and its cognate genera, but by means of Prionus and some new genera, with the great Capricorn group, I hope to make evident hereafter. I must observe here, however, that there is a certain group of the Misteride which appears to make a near approach to the Scolytide: the group I allude to has been formed into a genus, under the name of Tryponceus by Eschscholtz,} formed of three Bostrichi of Fabricius, viz. B. thoracicus, B. proboscideus, and B. pustulatus; which indicates that a road may be formed from the lignivorous HMisteride towards Scolytus, &c. LXV. Genus HISTER. Linn.

( Payhullii) ater, nitidus, cubitis tridentatis : dente exteriori fisso ; prothorace utrinque bistriato: stria exteriori abbreviata : elytris striis sex discoidalibus, nempe tribus exrternis distinetis integris, tribusque internis ex punctis conflatis, abbrevialis. Paykull’s Hister, black, glossy, cubits armed with three teeth, the outermost cleft: prothorax with a double furrow on each side, the exterior one abbreviated: elytra with six discoidal furrows, the three external ones entire and distinctly drawn, the three internal ones abbreviated and composed of punctures. Length of the body 3% lines. One specimen taken in the Journey from New York to Cumberland-house. DESCRIPTION. Body black, glossy. Head circumscribed by a rather deeply ploughed furrow; antenne piceous with 2 pale knob; mandibles longer than the head: prothorax rather wider behind, seemingly quite smooth, but under a strong magnifier it appears thickly covered with very minute lightly impressed punctures ; it is circumscribed on all sides, by a deepish furrow, between this furrow and the lateral margin is another abbreviated one jess impressed; elytra besides a distinct marginal furrow 1 Zoologischer Atlas Erster Heft. 10, 11. 124 NORTHERN ZOOLOGY. have three discoidal subpunctured ones running from the base to nearly the apex; between the ex- ternal discoidal furrow and the margin is a series of punctures near the apex, representing what is called the marginal furrow, and between the internal one and the suture are the traces of three others, the first just discernible, drawn, but interruptedly, from the base to the apex; the second consisting of three or four punctures near the apex, and the third parallel with the suture, con- sisting also of punctures, sometimes confluent, and extending from the apex not quite half the length of the elytrum; the surface of the elytra is covered with minute punctures very lightly impressed, so as not to be discoverable except under a good magnifier: the cubit or anterior tibia is armed with three teeth, the last of which appears cleft from its being furnished at the apex with two short truncated transparent bristles, the two other teeth have only one such bristle. This species, which belongs to Mr. Stephens’ family, A. a. 2,? differs in its sculpture, from any Hister at present known. Its aspect is that of HZ. unicolor, with which it likewise agrees in size, and many other characters, but it belongs to the section with the sides of the prothorax ¢wo- furrowed; whereas, in H. wnicolor, they have only one furrow; the elytra likewise of H. Payhullit are punctured, which in the species just mentioned are perfectly smooth, even when viewed under a powerful magnifier. (173) 2.* Hisrer Harrisu. Harris's Hister. H.

Body black, glossy, thickly punctured, the punctures on the upper-surface, being most conspi- cuous. Head circumscribed; antenne and palpi nearly of a mahogany colour; mandibles longer than the head; nose slightly impressed: prothorax with two furrows at the lateral margin, both nearly reaching the base, the inner one, as usual, when arrived at the anterior margin, with the corresponding one on the other side forming one furrow surrounding the prothorax on three sides; just above the scutellum is a punctiform impression: the elytra, including the submarginal one, have seven distinct furrows, the two next the suture being anteriorly abbreviated and very short, especially the first; from the base of the first, or external discoidal one, an obsolete furrow runs obliquely towards the submarginal one; the four discoidal entire furrows when arrived near the apex of the elytra are bent towards the suture: cubit piceous, armed with five teeth, the three outer ones obtuse. 2 Cat. 100.

The larger female was taken, I believe, in the province of Massachusets, by Mr. Drake. The species of this little interesting genus, remarkable for the great variety of processes resembling horns, that arm the head of the males, are as widely dispersed as those of any genus of beetles; they are to be found in every climate from the frigid to the torrid zone, nor do they increase in size as they recede from the former and enter the latter, for the most minute species are to be found in Southern India, where they abound, while the largest seem to inhabit temperate climates. DESCRIPTION. Body entirely black, except the hands or anterior tarsi, which are rufous: gloss obscured by hairs. Nose at the apex bent upwards, forming a vertical, triangular, acute tooth; on the vertex are two obsolete transverse ridges: the prothorax is rough with little granules, and anteriorly sends forth a longish wide horn truncated at the end and overhanging the head: the two angles of the apex are elevated, and the space between them is deflexed, and bidentate: the cubits are armed with four sharpish teeth. ? The female differs from the male merely in having the shield of the head more distinctly notched on each side, and the apex of the nose rounded and reflexed, but without any triangular horn or tooth; in having two distinct ridges on the vertex, and in having no prothoracie horn, which is re- placed by a transverse emarginate ridge in the middle. 126 — NORTHERN ZOOLOGY.

The following differences in their characters induce me however to consider them as distinct. Not to mention the difference of size, the female of O. datebrous has a distinct notch on each side of the head, of which there is no trace in O. scabricoilis, the ridges of the vertex of the latter are more elevated, the prothorax is larger in proportion and much rougher, with larger and more numerous granules, and the four teeth of the cubit, which in the former are long and acute, in the latter are shorter and obtuse. 8.

Body very minutely punctured, glossy, black, underneath a little bronzed, above luteous. Head black at the base, with the blackness bilobed; punctures of the nose confluent; antennz luteous; palpi black: prothorax, as well as the head, darker than the elytra; sides confluently punctured, a round blackish spot on each side near the lateral margin: scutellum black, a little bronzed, with a basilar luteous spot: elytra with three distant black-brown spots or dots, the first and last oblong, the middle one round; breast, and base of the abdomen, hairy with long hairs: legs black, a little bronzed ; cubit tridentate. 3 The Rutelide exhibit the vertical prosternum of the Dynastide, which is wanting in the Anoplognathide, I therefore consider them, with Latreille, as more immediately connected with the former family, and have placed them accordingly. 128 NORTHERN ZOOLOGY. 8B.

Mandibles very short, subtrigonal, curving, without teeth; molary space subtriangular, surface furrowed, the outer margin appearing denticulated from the ridges of the furrows being more elevated there, on the opposite side there appears to be a kind of channel. Mazille linear, incurved at the tip and terminating in four stout teeth. Labium oblong, forming one piece with the mentum; narrowed, subemarginate, and sloping inwards at the apex. Palpi mazillary, four-jointed, gradually incrassated: first joint very minute, second obconical ; third of the length of the second, thicker; fourth as long as the second and third together, rather oblong. labial, three-jointed, filiform: last joint as long as the two first together. Antenne nine-jointed: scape much incrassated at the apex; the pedicel less incrassated, spherical- oblong; the two following joints rather filiform; the fifth and sixth shorter and inclining to pateriform; and the three last elongated and forming a rather slender knob. Body oblong, subcylindrical. Head inserted, subtriangular, with the vertex of the triangle anterior, truncated; nose short, transverse, distinct, reflexed, separated from the postnasus on each side by a cleft; nostril-piece inflexed, transverse, and nearly vertical; postnasus distinct, depressed, curved; front convex; eyes subhemispherical ; canthus septiform: prothorax transverse, with an anterior sinus taken from its whole width to receive the head, posteriorly subrepand: scuteliwm an isosceles triangle: elytra linear: breast-bones not prominent: medipectus or midbreast elevated: legs thus located ;;; tarsi subsetaceous ; claws two, very short, incurved, each bifid or bipartite, with the lobes acute: podex only partly covered. This genus is very nearly related to Serica of Mr. W. S. Mac Leay. It differs, however, in the number of teeth that terminate the maxilla, having only four instead of six; in having both the lobes of the claws that arm the tarsi acute, whereas in that genus the inner one is truncated, and in having none of the silky bloom which the species of Serica usually exhibit. Mr. Mac Leay speaks of its antenne being ten-jointed, this, if correct, would furnish another striking distinction, but in S. brunnea, the type of the genus, under a very strong magnifier I can perceive only nine joints, and M. Latreille in this agrees with me.° 4 This tribe is distinguished by having no prominent prosternum or mesosternum. > Crust. Arachn. et Ins. i, 562.

Body between oblong and obovate, not hairy. Head inserted, subtriangular with the vertex of the triangle truncated; riinarium transverse, vertical, widely emarginate; nose transverse, distinct, anterior margin reflexed and subemarginate ; no distinct postnasus or afternose ; canthus septiform, cleaving :’ prothoraz transverse with an interior sinus of its whole width to receive the head: scutellum short, triangular, somewhat rounded at the vertex: podex and part of the penultimate dorsal segment of the abdomen uncovered: legs thus located **; cubit tridentate; tarsi filiform, slender: claws bipartite, the interior lobe the shortest and widest, and very obtuse; the exterior very slender and acute. This genus, at the first blush, seems to exhibit some affinity both with Chalepus and Apogonia ; with regard to the latter, this arises merely from its having few or no hairs, and from its rows or punc- tures in pairs observable in the elytra; but with the former it agrees in more particulars, for its mandibles are truncated at the apex and concavo-concave, as those of Chalepus are represented, and correctly, in Mr. Mac Leay’s figure ;* the antenne likewise are not very different, except that the scape in the latter insect is more dilated at the apex: but this exhibits a character which at once separates it, and widely, from D¢plotaxis, the prosternum sends up a vertical process behind the base of the arms, hairy at its summit, a character which is to be detected, but more or less conspi- cuously, in all the various genera and subgenera that form Mr. Mac Leay’s large family of Dynas- tide though it is less prominent in Megasoma, the most gigantic genus of them all. The maxilla, often so constant, in this family or rather tribe, vary without end, the mandibles are more constant, as is also the labium, but the vertical prosternum,” varying as to elevation and shape, is their constant diagnostic: so that it is evident that Chalepus is one of those intermediate forms which connect two tribes or circles; allowing this, and that the Rutelide also and Anoplognathide are intimately connected with the Dynastide,! we have another instance of unconnected ramifications, which lead by different routes to different tribes. It may be here not out of place to observe, that in the true Rutelide, there is the vertical prosternum of the Dynastid@, and the horizontal projecting mesos- ternum? of the Anoplognathide, which last have no elevation of the prosternum.

DIPLOTAXIDZ— MELOLONTHIDE. 131 I at first regarded this species as a variety of Melolontha mesta of Knoch, but upon comparing it with Germar’s description,’ it appears quite distinct ; for it is not at all bronzed, the nose is not rounded, and the four posterior tarsi, especially the intermediate pair, are longer than the tibie. It comes very near to Say’s M. meesta, (which is quite distinct from Knoch’s,) from which it is principally distinguished by its impunctured scutellum. DESCRIPTION. Body dark chestnut, more or less grossly punctured above and below. Head thickly punctured with a pair of impressions between the eyes; nose subemarginate ; antenne and palpi rufous: pro- thorax thickly punctured, slightly impressed at the four angles: scutellum impunctured: elytra rather paler than the head and prothorax, with nine rows of punctures, viz. a single one at the suture, four arranged in pairs in the disk, and four in the sides; the interstices between the rows are also irregularly punctured; the four posterior tarsi, especially the intermediate pair, are longer than the tibie.

Latreille, in his last work,®5 has united to this genus Amphimalla solstitialis, which on account of its having only nine joints in its antenna, he had, and I think with reason, considered as distinct ; for besides this character, the mandibles are of a very different shape, being shorter and smaller in proportion to the size of the animal, with the truncated portion narrower and concavo- convex; the maxille are armed with only four teeth, and are more incrassated at the base; the claws have only a minute tooth at the base, and the elytra are many-ridged, besides other minor differ- ences; I think, therefore, I am justified in still considering them as belonging to different genera. Rhizotrogus should be placed between Amphimalla and Melolontha, from which last it may always be distinguished by having only three leaves in the knob of its antenne. As Latreille’s character of the genus is insufficient, I have drawn up a new one. (180) 1. Ruizorrocus FERVENS. Fervid Rhizotrogus. Melolontha fervens. Gyll. Schén. Syn.iii, App. 74, 106 ferivida.

I had call.d it Stenia. 134 NORTHERN ZOOLOGY. This genus evidently belongs to the same family with Macrodactylus, from which it is distin- guished by having its maxilla armed only with two teeth, the last joint of its palpi of a different shape, and its labium approaching to a square form: whereas in the latter genus the maxille are more conspicuous and armed with three teeth, the last joint of the palpi is subovate, and the labium is oblong and channelled. The species of this genus, as far as at present known, appear to be confined to the more northern parts of the new world; I have seen none south of the province of Massachusets, from whence I have received specimens both from Dr. Harris and Mr. Drake. ‘Type of the genus Melolontha linearis Herbst.” (182) 1. * DicuELonycua Bacxu.

Dr. Harris sent me a specimen of D. virescens as the Melolontha linearis of Herbst and Schénherr, but it is not likely that so accurate and minute a describer as Major Gyllenhal, who usually lets no character escape him, should have overlooked the dorsal channel and lateral impres- sions of the prothorax of this species. Besides the colour and other characters do not agree.® (184) 3. * DICHELONYCHA TESTACEA. Testaceous Dichelonycha. D. (testacea) tota rufo-testacea ; elytris subvirescentibus, capite prothoraceque minutissime punctulatissimis. Testaceous Dichelonycha, entirely rufo-testaceous ; elytra with a slight tint of green; head and prothorax very minutely and thickly punctured. Length of the body 44 lines. Taken by Dr. Bigsby in Canada. DESCRIPTION. Very similar to Variety C of the preceding species; but the body, with the exception of the eyes which are black, is entirely of one colour, rufo-testaceous, the head, prothorax, and tarsi being rather darker than the rest; the eyes are larger and more prominent; the head and prothorax, especially the latter, are more thickly and minutely punctured ; and in this there is no dorsal chan- nel; its margins, especially the lateral, are more hairy, the elytra exhibit no humeral or apical green spot; and they are very slightly tinted with that colour. 8 Schon. ubi supr. 136 NORTHERN ZOOLOGY. c.

Body obovate, black, covered more or less with tawny longish hairs. Head quadrangular ; nose reflexed, emarginate ; antennz and palpi luteous, black at the tip: prothorax trapezoidal, nar- rowest anteriorly, sides rounded or subotusangular, posteriorly with an obsolete sinus near each angle: scutellum short, rounded at the apex: elytra without hairs, covered as it were with a bloom; luteous with a black margin and nine black spots—viz. one large one at the shoulders, seven in the disk arranged transversely 2, 3, 2, and one larger than the rest on the apical tumour; the humeral and apical spots are glossy : three tawny-yellow mealy spots, the intermediate one straight and longi- tudinal, and the lateral ones sinuated and oblique, mark the podex : the tibie and tarsi of the four anterior legs are deep ferruginous; cubit bidentate. x. ® Subgenus Tricuinus.

The insects that compose this little group, as far as at present known, are all North American; and are distiuguished from the legitimate Trichii (Legitimi K.) by having the last joint of the palpi more slender, and the elytra hairy without any of the bloom observable in these of 7. fasciatus, Bigsbii, &c.

Length of the body 44—5 lines. Taken in Lat. 65°.; in Nova Scotia by Capt. Hall; and in Massachusets by Dr. Harris. 138 NORTHERN ZOOLOGY. DESCRIPTION. Body obovate, black, covered more or less with long yellowish hairs. | Head punctured; nose reflexed, emarginate; stalk of the antennz testaceous, scape and knob black; palpi dusky: protho- rax punctured, less hairy in the disk, not channelled: elytra black, very short, depressed next the suture with an intermediate ridge; at the base is a large pale-yellow spot common to both elytra, from which run a pair of narrow, white, mealy bands, which nearly reach the external margin, and a white mealy stripe adjoining the suture also runs from the same spot to the apex of the elytrum: the podex is covered with long yellowish hairs, so thick on the sides as almost to conceal the oblong white mealy spot common to the subgenus: legs black. N. B. In the specimen taken in the Expedition, the white mealy stripe next the suture appears to have been rubbed off and is replaced by a continuation of the pale spot. There appear to be many species of this subgenus. That now described Dr. Harris thought might be a variety of 7. piger F, but it differs from that species not only in painting, but also in sculpture and cloathing ; for it has no channel on the prothorax, which is very conspicuous in the former insect ; the podex is covered with very long and dense hairs so as to conceal the lateral mealy spots, while in 7. piger the hairs are very short and the mealy spots very conspicuous. ‘The head and thorax of the latter are bronzed, the whole of the antenne testaceous, the elytra, podex, and legs® also, are testaceous, the former with a pair of abbreviated lateral bands, but no sutural stripe. So that 7. assimilis is clearly distinct. (188) 3. * Tricuius (Trichinus) rotunpicotus. Round-necked Trichinus. T. T.

Length of the body 54 lines, Taken in Nova Scotia by Capt. Hall. 9 Olivier’s Cetonia pigra (Ent. i, 6, 64, 78, t. vii, f. 54) is described as having the legs black-bronzed. If this is not an error it must be a distinct species. TRICHIADA. 139 DESCRIPTION. Body obovate, black; covered, particularly underneath, with longish pale hairs. Head very thickly punctured; nose reflexed, emarginate ; stalk of the antennz, excluding the scape, testaceous : prothorax suborbicular, with the segment of a circle taken out next the head; very thickly punctured, channelled, sprinkled with short yellowish hairs; at the side of each of the four angles is a mealy- white spot: the elytra next the lateral margin have two transverse mealy-white streaks or bands, which are continued towards the suture by a broader, naked, ferruginous, obscure band ; just below the scutellum, on each elytrum, is another mealy stripe, and parallel with the suture is an obscure, naked, ferruginous one: podex hairy with the ordinary mealy pale spots very conspicuous ; it is sculptured with transverse undulated lines: cubits robust with two stout teeth: a mealy spot marks the base of the posterior legs.

Trichinus, above green, underneath with pale hair: prothorax subtrapezoidal, channelled; elytra with two bands internally testaceous, externally, as well as a line before the scutellum, mealy-white. Length of the body 4e lines. A single specimen taken in Canada by Dr. Bigsby. DESCRIPTION. In the markings of its elytra this species agrees precisely with that last described, but the upper side of the body, especially the head and prothorax, is green; the latter is of a different shape and less thickly punctured; and the cubit and its teeth are less robust: the podex also is more hairy. These can scarcely, all of them, be mere sexual distinctions. It seems intermediate between 7. rotundicollis and T. viridulus. xi. * Subgenus Gymnopus. Kirb. Gymnodi. Kirb. Zool. Journ. iii, 157, *******. This is a very natural group of the genus Trichius, the species of which are common to Europe and North America. The type of it, 7’. Eremita, has long been known as a European insect. It was first noticed and figured by Résel, and re- ceived its present name from Scopoli.! The species that compose it are nearly naked, and without any mealy spots: the nose is truncated, and the cubit is tri- dentate. It appears to make a near approach to the South American Goliathi.

Length of the body 114 lines. Taken in Nova Scotia by Capt. Hall. DESCRIPTION. Near the preceding species, but perfectly distinct. Body nearly naked, somewhat glossy, of a dark pitch-colour. Nose and front between the eyes with a very deep and large impression, the bed of which is acuducted in circles with a minute puncture in the centre of each; the rest of the head is confluently punctured; above the bed of the antenne the front rises into a rather lofty levigated prominence: the prothorax is shaped like that of G. rugosus, but is rather less obtusangular, the channel is deeper, with its sides more elevated, and there are one or two slight impressions between it and the margin; the punctures on the disk are rather more numerous: the elytra are paler than the rest of the body and a little bronzed, the wrinkles of the surface are more vermiform than in the species just named, without any punctures, and the appearance of furrows is less distinct: the podex is distinctly punctured and scarcely acuducted ; and the cubit is sinuated rather than dentated, the three prominences being extremely obtuse. LUCANIDZ. 141 iu. RECTOCERA. Having finished the petalocerous or rather orthocerous Lamellicorn beetles, we must next proceed to those the stalk of whose antenne mostly forms an angle with the scape, so that these organs appear as if they were broken, which, as was before observed,? form one branch of Mr. Mac Leay’s Rectocerous beetles. These are not to be regarded, though they exhibit an analogical relation, respect being had to their food, as following the Trichiade in the line of affinity, but in order to link them to their apparently nearest relatives, we must retrace our steps to the Histeridee, where we shall find a tribe that are lignivorous, of a depressed form, and with more than usually protended mandibles, of which Hololepta mavillosa may be regarded as the type :4 it is towards these that the Lucanide appear to tend, at one extremity, though still many forms are wanted to fill the interval. Although I have not altered Mr. W. S. Mac Leay’s denomination of the tribe before us, it must be observed that, in some families belonging to it, as the Lam- primide, Passalide, &c. the antenne are not broken. ‘The family last mentioned, the Passalid@, is not only distinguished by the stalk of the antenne not forming an angle with the scape, as in the Lucanide ; but the form of the insects that com- pose it, is narrower, more cylindrical, and less depressed. From this family, as we shall see hereafter, a branch appears to diverge, by the Bostrichidans to the great Rhynchophorous tribe. Family LUCANIDZE. Lucanidans. LXXV. Genus PLATYCERUS. Lat. (192) 1.

Body dark piceous, rather glossy, thickly punctured. Nose very retuse, or rather with a large sinus; mandibles shorter than the head, acute, armed on their inner side with a stout tooth with the segment of a circle taken out of it; antenne pale chestnut: prothorax with the lateral margin obtusangular, subcrenate, and reflexed; disk longitudinally impunctured, and obsoletely channelled : scutellum channelled, impunctured : elytra furrowed : cubit serrulate and denticulate, two sharp teeth longer than the rest at the apex; tarsi chestnut. This is the smallest species of the stag-beetle tribe. As Schénherr has not placed it under Pla- tycerus, but under Lucanus, and as the insect here described is a true Platycerus, it should seem that he either did not know Z. piceus, or that I am mistaken in my reference. My specimen agrees exactly with the short description in the Systema Eleutheratorum, but I have no opportunity of consulting Weber. Family PASSALIDZE. Passalidans. LXXVI. Genus PASSALUS. (193) 1.

Body black or piceous, underneath sometimes rufo-piceous, impunctured, glossy. Head with a crooked horn between the eyes pointing towards the mouth, and a triangular elevation adjoining each eye on the inner side; labrum with a deep sinus; mandibles with three teeth at the extremity, and one in the middle of the upper side; knob of the antenne consisting of three hairy joints, the outer one thicker than the others and curved: prothorax channelled, impressed on each side near the base; under a powerful lens several scattered very minute punctures may be discovered on its surface; the ora, or undersides of the prothorax,° are likewise punctured, and soft with tawny hairs: elytra furrowed; furrows punctured: cubit many-toothed; intermediate tibia densely bearded, on the outside, with tawny hairs. The bent or nodding horn on the head of the species here described has generally been taken for a sexual character; but I am inclined to regard this as a mistaken notion. Specimens thus circum- ® See Introd. to Ent. iii, 368, i, 1, a. PASSALIDE—STERNOXA. 143 stanced, as far as I have been able to ascertain, have hitherto been found only in North America; while those with a tuberculated head are found in various parts of South America, in the East and West Indies: and I have one in my cabinet from New Holland. Eleven specimens of the former were collected in the Expedition, varying in size, and not a single one of the latter. As Linné describes his Lucanus interruptus, ‘* Vertice spina recumbente,” a character peculiar to the species here described, I have restored to it its proper name, which Fabricius in his last work, had assigned to the South American species with a tuberculated vertex : calling the North American one or true Passalus interruptus by the trivial name of P. cornutus. ‘These two species, which have been regarded as sexes, differ not only in the processes that arm the head, but also in the labrum, the sinus being deeper in one than in the other: the cubit in the Linnean P, interruptus has more teeth than in the Fabrician, and the intermediate tibia is much more thickly bearded. At the first blush, the most direct course next to pursue would be from the Rec- tocera by one route towards the Capricorn beetles, and perhaps by another in the direction of some of the Heteromera: but a different and numerous tribe of beetles demand our attention before we leave the Lamellicorns. Latreille has placed his Sternoxi, forming the tribe alluded to, and including the great Linnean genera Buprestis and Elater, at the head of his family of Serricornes, which with him succeeds that of the Brachelytra or Staphylinus L. and is followed by his Clavi- cornes, including most of the beetles that prey upon carrion :° but this, as has been observed above,’ separates tribes that ought not to be disunited; and I cannot help thinking, with Mr. W. S. Mac Leay, that their place ought to be much nearer the Lamellicorns. This learned Entomologist includes both in the same great section, under the title of Chilognathiformes or rather Chilognathimorpha,® but what precise place he assigns them, he has nowhere clearly stated. Many inter- mediate forms, however, as yet undiscovered, are wanted to connect the Sternova evidently with the Lamellicorns. As many of the Elateride, and I believe all the Buprestide are timber-devourers, I shall venture at present to regard them as entitled to a station somewhere between the lignivorous Lamellicorns and the Capricorns, with which last in their tarsi, the Buprestide particularly, exhibit con- siderable affinity. Regarding the groups from which they diverge, and those to which they direct their course, as not yet indicated I shall now describe the species of Sternoxa taken in the Expedition. ® Crust.

Latreille appears to consider the Fire-flies (Elater noctilucus and affinities) as the type of the genus Elater ;? Linné and Fabricius those with flabellated antenne, as E. gigas and flabellicornis: but as the latter, though large insects, have a very short pectoral mucro, it is probable that their power of leaping! is less than that of the others; therefore the name Elater does not equally well apply to them, and it will be better to distinguish them by M. Latreille’s name Hemirhipus, considering E. noctilucus, &c. as the true laters. There are several types of antennz in this family, all of which appear to run into each other—viz. flabellate, pectinate, serrate, submoniliform, filiform, and subse- taceous ; as there are likewise of tarsi, which perhaps afford a more certain charac- ter, combined with others, for the distinction of genera and subgenera. Thus the majority perhaps of the Elateridans have neither suckers, nor cushions of hairs, e.g. E. fascicularis, pectinicornis, Sputator, fasciatus, mesomelus, &c.: others again have a single sucker on the fourth joint, this is the case with three American un- described species in my cabinet: a third description, have a cushion edged with hairs on the second and third joints, E. obscurus, &c. Linn? Payk. E. ruficaudis Gyll.: another species, brought, I believe, from the West Indies by Admiral Plampin, has three transverse reniform suckers on the second, third, and fourth joints: in E. niger again the apex of the first, second, and third joints is furnished with a brush ; in £. ligneus, suturalis, and affinities, there are three large suckers on these joints: in E. flabellicornis there is a naked cushion or sucker on the four first joints, that on the fourth being the largest: and lastly, in EZ. noctilucus, fuscipes, fulgens, &c. the same joints are furnished with a brush. 9 Crust.

This is the American representative of C. mesomelas, from which it is sufficiently distinguished by its toothed antenne and longer prothorax. Body linear, black, hairy with pale decumbent hairs. Head punctured; antennz longer than the prothorax, filiform, with all the joints, except the scape, pedicel, and terminal one, terminating at their internal extremity in a prominent tooth, less conspicu- ous in the two lower ones; upper-lip, and nose which is reflexed and overhangs the mouth, yellow : prothorax channelled, punctured, quadrangular, with the anterior angles rounded, and the posterior diverging and terminating in a sharp tooth or prominence; sides rather wavy; limb yellow: scutel- lum subcordate: elytra minutely and thickly punctured, slightly furrowed, furrows thickly punctured; marked with a narrow yellow stripe which does not reach the apex; there is also a short yellow streak on the shoulders: base of the tibie, claw-joint of the tarsi, and claws, yellow. LXXVIII * Genus PEDETES. Kirb. Labrum transverse. Mandibles bidentate at the apex. Palpi maxillary, with the last joint securiform. Antenne filiform, not retractile within the prothorax.

Head inserted to the eyes; eyes large and hemispherical; nose anteriorly rounded or subtruncated, and reflexed, overhanging the mouth and base of the antenne ; rhinarium transverse, inflexed, concave: prothorax elongate, subquadrangular; anterior angles pro- minent, rounded; posterior scarcely diverging, prominent, dentiform: scutellum somewhat obcordate: elytra rounded at the apex; side-covers at first coulter-shaped, then linear : prosternal mucro long and rather slender. This genus, the type of which is LZ. obscurus L. and Payk. EL. ruficandis Gyll.? approaches very near to Campylus, from which it is principally distinguished by a more convex and longer pro- thorax, the posterior angles of which are scarcely divergent; but more particularly by the suckers at the apex of the second and third joints of the tarsi: the last of which are lobed. * That the Linnean E. obseurus is a long narrow insect, and therefore not the E. obscurus of Gyllenhal, is evident from his comparing it with Z. linearis.

I am doubtful whether this should not be considered as forming a distinct genus. The general form is very different.

Nose rounded, overhanging the mouth; rhinarium deep; eyes large, hemispherical: prothorax short, convex, narrowest before ; anterior angles not prominent, posterior elongated, dentiform, above with a sharp ridge: scutellum subquadrangular : elytra linear, attenuated at the apex: prosternal process long, suddenly attenuated at the apex: tarsi filiform, hairy, without suckers, cushion, or brush; claws distinctly pectinated. This genus, of which Eater fulvipes is the type, is distinguished from all the other Elateridans by having its claws finely pectinated, a character in which it agrees with Lebia and many others of the Truncipennia amongst the Geadephaga, ‘This striking distinction has been overlooked by Gyllenhal and all the other Entomologists who have described this insect. I had originally named this genus Ctenonyx, but Mr. Stephens having distinguished another by the name of Ctenonychus, probably related to Llater unguli-serris of Gyllenhal,? under the idea that the type of the genus is H. fulvipes Linn. I have adopted the name given by Mr. Dillwyn, to distinguish that insect, as forming a new genus: still some doubt rests upon the identity of their specimens with the American: as Mr, Stephens describes the eyes as small, whereas in my specimen they are large, but this may be a sexual character. * Schon.

DESCRIPTION. I should have given this as merely a variety of the last; but besides its blacker body, the punc- tures of the prothorax are not nearly so numerous, and there is no appearance of its being channelled : the breast is chestnut.

Head with two impres- sions between the eyes; nose subemarginate ; antenn shorter than the prothorax, serrated: prothorax longer than wide, channelled, posterior angles diverging, very acute, carinated: scutellum suboval, covered with white hairs: elytra rather wider than the prothorax, testaceous with a black discoidal blotch at the tip; slightly furrowed with punctures in the furrows ; interstices punctured : legs piceous. This species, which is a female, is related to Ct. cupreus, but is much wider in proportion to its length. LXXXI. Genus ELATER. Linn. xiii. * Subgenus Apruotisrus. K we may observe here that the genus Spondylis, though placed by Latreille amongst the Prionidans seems to furnish a link connecting the Platysoma, to which it surely belongs, with another family of Capricorns the Lamiadans; and particularly with a genus, or subgenus, belonging to it, the type of which is Lamia vermicularis of Donovan.6 2 De Geer iv, 351, 2, t. xix, fi 14. 3 T call it Gnathophorus. + Oliv.

Length of the body 103 lines. Frequently taken in Lat. 65°. 7 As neither De Jean nor Latreille have given characters of this genus I subjoin them. 168 NORTHERN ZOOLOGY. DESCRIPTION. This insect resembles M. sutor in so many particulars, that it is not without considerable hesi- tation I describe it as distinct. It exhibits however some characters that seem to indicate more than a casual variety, produced by difference of climate, &c. The antenne of the male of M. resutor are considerably shorter than those of the same sex of M. sutor; the lubrum and rhina- rium are shorter; the former is rufo-piceous; the first joint of the antenne, the five or six of the last joints are rufescent, as are the legs more or less, and the tooth that arms the intermediate tibia is more prominent. The antenne of the female are but little longer than the body, and not annu- lated with cinereous. This species is intermediate between M. sutor and M. sartor. * * Elytra without wrinkles.

Length of the body 1 inch and 13 line. Taken in Nova Scotia by Dr. Mac Culloch, in Canada by Dr. Bigsby, in Massachusets by Mr. Drake. DESCRIPTION. Body linear, elongate, black, covered with white or cinereous decumbent hairs, but so as to let the black appear in confused spots and reticulations. Labrum rather long, fringed anteriorly with fer- ruginous hairs; maxillary palpi long; rhinarium broad, rufous ; antenne testaceous with the redness obscured by decumbent cinereous hairs, but the scape and pedicel are black; the antenne of the female are something longer than the body; those of the male are twice its length: the spines of the prothorax are stout, covered thickly with white hairs, and dotted posteriorly with black; in the disk is a central oblong impression: scutellum thickly covered with white decumbent hairs, with a black longitudinal line: the ground colour of the elytra is testaceous which is more or less obscured and clouded by white decumbent hairs, besides there are several black dots and oblong spots pro- duced by erect hairs; at the base of the elytra, especially on the projecting shoulders, are numerous round elevated smooth little spaces, and their whole surface is covered with scattered minute punctures. N.B. In the male the black spots and dots of the elytra are fainter, and sometimes nearly obliterated. CERAMBYCID. 169 (223) 3. * Monocuamus MARMORATOR. Marbled Monochamus. M.

Anus of the female with a long exserted ovipositor. The type of this subgenus is Cerambyx fasciatus of De Geer.’ It comes near to Acanthocinus edilis, the female of which has an exserted ovipositor, but not so long, and the scape of the antenne is of a different shape; so that they would, if con- sidered as belonging to the same subgenus, form two divisions.

Length of the body 44 lines. A single specimen taken in the Journey from New York to Cumberland-house. 5 De Geer v, J14, ¢. xiv, fi 7. Z 170 NORTHERN ZOOLOGY. DESCRIPTION. This species is one of the most minute of the Capricorn tribes. Body linear, black but covered with a coat of whitish decumbent hairs, which appears more or less sprinkled with black dots. Head longitudinally channelled; antenne mutilated in the specimen, but those joints that remain are white at the base: prothorax short, armed on each side, towards the base with a short sharp spine, punc- tured with scattered punctures; elytra punctured especially towards the base, mottled and speckled with brown, with an oblique brown band a little beyond the middle, apex of the elytra rounded : podex and hypopygium, or last dorsal and ventral segments of the abdomen elongated, so as to defend the base of the ovipositor which is exserted, causing the insect to appear as if it had a tail; the hypopygium is emarginate: thighs much incrassatad at the apex.

(agreste) fuscum, subobscurum, punctulatissimum ; prothorace, trifoveato ; elytris lineis tribus elevatis apice confluentibus: corpore subtus albido villoso ; pectore longius. Country Callidium, brown, less obscure, very minutely and thickly punctured; prothorax with three impressions; elytra with three elevated lines confluent near the apex; body underneath coated with white hairs, those on the breast being longer than the rest. Length of the body 11 lines. Several specimens taken in the Expedition, and likewise in Nova Scotia by Dr. Mac Culloch and Capt. Hall. DESCRIPTION. I at first took this for a variety of C. rusticum, but on a closer inspection I found it differed in the sculpture as well as colour; and having received a specimen of that insect from Dr. Harris, in which its characters were all preserved, I am induced to describe C. agreste as a distinct species. It differs from C. rusticum in being smaller, of a darker brown, without a tint of red; and in having more gloss. The prothorax has three deep round impressions, while in the insect last named, the impressions are slight, and the two anterior ones oblong: the elevated lines of the elytra are more prominent and become visibly confluent towards the apex, where they form several reticulations: the underside of the body is much more thickly covered with hairs, which are hoary instead of yellowish, those on the breast being longer than those on the abdomen. In other respects these two insects resemble each other. CALLIDIADZE. Wl (226) 2. * Catiipium striatum. Striated Callidium. Callidium striatum. Fab. Ent. Syst. I, ii, 829,48; Syst.

DESCRIPTION. Body linear, black, hairy with whitish scattered hairs. Head thickly punctured; antennz shorter than the body, rather hairy, piceous, scape black: prothorax rufous, with a few scattered punctures, glossy, projecting on each side into an angle or short spine: elytra very thickly and confluently punctured: body underneath glossy, slightly punctured: anterior part of antepectus rufous: tarsi piceous, first joint of nearly equal length in all the legs. This species seems to be nearly related to C. sanguinicolle of Germar,? but it differs in having the thorax less punctured than the rest of the upper surface of the body, and armed with rudiments of spines, and the first joint of the posterior tarsus is not more elongated than the rest. 9 Coléopt.

Length of the body 7 lines. A single specimen taken with the preceding species. DESCRIPTION. This species in most respects is so like C. M. Proteus, that I had set it by as another variety ; but upon further consideration I am induced to give it as distinct, since it differs not only in colour but in the form and sculpture of the prothorax and other parts. The apex of the palpi is more dilated, so that it is strictly securiform; the front behind the antennz is elevated and gibbous, with few scattered punctures: the sides of the prothorax are more puffed out, and much more minutely and thinkly punctured, and there is a pair of impressions in the disk: the antenne also at the base are rufous: in other respects it does not differ from M. Proteus. (230) 6. CaLuipium (Merium) pimipiatum. Halved C. Merium. C. M. (dimidiatum) obscure rufum, supra nigrum ; elytris antice rufis ; prothorace granulato, postice canaliculato. Halved C.

Body not glossy; impunctured; hairy underneath; and except the forebreast, which is black, of a dull rufous. Head channelled between the eyes, behind them convex; antenne rufous, shorter than the body: prothorax somewhat coarctate at the base; minutely granulated; obsoletely chan- nelled, more conspicuously behind: elytra rufous anteriorly. This species comes very near to C. (Merium) Alni, but it is larger and has no white bands. = ne 174 NORTHERN ZOOLOGY. xxi. * Subgenus TretTropium. Kirb. Eyes four, connected by an elevated line.! Antenne robust, short: scape much incrassated, subcylindrical, remaining joints subclavated. Prothoraz constricted anteriorly and posteriorly. Thighs much incrassated, sometimes clubbed. The type of this subgenus is Callidium triste Fabr. for those with clavated thighs, and C. aulicum, for those in which they are incrassated nearly their whole length. These insects will be found to have four distinct eyes, separated by the substance of the head elevated into a ridge, which at first sight appears a continu- ation of the eye, but which evidently has no lenses implanted in it—they are also distinguished by their-robust and short antenne.

Several specimens taken in Lat. 65°. DESCRIPTION. At first sight this species seems the exact counterpart of Callidium triste, which it resembles in almost every respect ; but upon examination it will be found that the thighs of these two insects are of a very different shape, those of C. T. triste being much attenuated at the base, while those of C. T. cinnamopterum are not at all. In the latter also the sides of the fore-breast are red, and the elytra are considerably darker, very near the colour of cinnamon. The American specimens vary much in size, but all agree in the shape of the thighs. 1 Plate V, Fig. 8, a. CALLIDIAD. 175 XC. Genus CLYTUS. Fab. * Prothorax subglobose unarmed. a. Yellow-banded.

Length of the body 73 lines. One specimen taken in Lat. 54°. Taken also in Canada by Dr. Bigsby, and in Nova Scotia by Capt. Hall. 176 NORTHERN ZOOLOGY. DESCRIPTION. This species is extremely similar to the preceding, but its bands and spots are quite white without any tint of yellow: the prothorax has no posterior interrupted band, the anterior spot of the elytra is crescent or kidney-shaped, the thighs are dusky; and the eyes are black; but the most striking distinction is exhibited by the head, which is perfectly smooth and without punctures, but when the occiput is disengaged from the prothorax, as it is when the head is inclined forwards, the front will be found to be separated from it by a bilobed line, behind which the head is thickly and confluently punctured, (234) 3.

The body appears to be black, but that colour is, in most parts, nearly concealed by a thick and mostly long coat of brilliant golden hairs with a very slight tint of green, where the coat is thin the body appears minutely punc- tured. Head subelongated, the neck exserted, subtriangular ; nose with only a few scattered whitish hairs; antennz black, third, fourth, and fifth joints rather slenderer and longer than the succeeding ones: prothorax between globose and bell-shaped, constricted anteriorly, channelled, grossly punc- tured: substance of the elytra pale testaceous, towards the apex externally they are dusky; the golden down on them is shorter and decumbent ; apex diverging and obliquely truncated: under- side of the abdomen particularly brilliant from decumbent hairs: legs less hairy than the rest of the body.

(similis) linearis, nigra, punctulatissima, corpore subtus ex pube subargenteo; elytris apice rotundatis ; antennis scapo femori- busque rufis. Similar Leptura, linear, black, very minutely and thickly punctured, body underneath, rather silvery from down; elytra . rounded at the apex; scape of the antenne and thighs rufous. Length of the body 3} lines, A single specimen taken in Lat. 65°. DESCRIPTION. This may possibly be the other sex of the preceding species which it resembles in every respect, except that the antenne are rather longer, the scape or first joint, all but the base on the upper side, is rufous, as are likewise the thighs and four anterior tibia; the posterior thighs are however black at the apex. (250) 12. * Leprura Lonercornis. Long-horned Leptura. L. (longicornis) nigra, elongata; elytris grosse punctatis, vitta pedibusque basi, testaceis ; antennis mediocribus. Long-horned Leptura, black, elongated, stripe of the grossly punctured elytra, and base of the legs, testaceous ; antenn as long as the body. Length of the body 5 lines. A single specimen taken in Lat. 65°. DESCRIPTION. At first sight this species a good deal resembles L. semivittata and gulosa of the former section, but its eyes are entire, and its antenne much slenderer and of a different type, more nearly resemb- ling those of L. argentata and similis. Body black, minutely punctured, downy, especially under- neath, with silvery hairs.

Proteus Leptura, black, subpubescent, rather glossy ; eyes entire, inclining to a golden lustre ; antennz, elytra, and legs © varying in colour; prothorax channelled, posteriorly with a gibbosity on each side. Length of the body 31—5} lines. Taken abundantly in Lat. 54°. and 65°. DESCRIPTION. Body narrow, black, punctured, somewhat glossy, rather hairy, especially underneath, with decum- bent hairs, those on the elytra have somewhat of a golden lustre, the rest are silvery. | Nose more grossly punctured than the rest of the head; vertex convex; eyes subovate, pale with a slight golden lustre; antenne filiform, longer than the prothorax, obscurely rufous, with the four first joints black, fifth joint longer than the fourth: prothorax campanulate, anteriorly constricted, posterior angles a little diverging; thinly punctured; channelled, the channel running between two dorsal gibbosities: scutellum triangular: elytra rather widest at the base, and punctured there more grossly next the suture; diverging and truncated at the apex: tibie piceous or rufo-piceous; four posterior thighs rufous at the base. Variety B. In this variety only the base of the six last joints of the antennz is rufous; all the thighs are rufous at the base, and the tibia of a clearer red, but they are dusky at the apex; tarsi rufous at the base. Length of the body 32 lines. C. Elytra with a stripe at the base, tips and lateral margin rufous: antennz entirely black: legs as in variety B. Length of the body 43 lines. D. Elytra with a longitudinal rufous stripe dilated at the base and apex; bead of the lateral margin also rufous: antenna and legs nearly as in B, but the whole of the tarsi is obscurely rufous. Length of the body 3—4 lines. EK. Elytra rufous with the suture and a stripe near the margin abbreviated at both ends, dusky: antenne as in A; legs as in B. Length of the body 4—5 lines. F. Elytra rufous, with a dusky suture; antenne as in A; legs as in D. G. Like F, but elytra luteous; antenne all black. Length of the body 4 lines. H. Like F and G, but legs and antenne black. Length of the body 3? lines. This species is the American representative of Z. femorata of Paykull and Gyllenhal, which is not clearly synonymous with that of Fabricius and Olivier, it differs, without mentioning colour, in having much shorter antenne, and in being glossy. Mr. Marsham’s ZL. femorata has reniform eyes, and therefore belongs to another section, it may be that of Olivier. L. Proteus seems to vary ad infinitum in the colour of the elytra, antenne, and legs, but as all the varieties agree in every respect except colour and size, and the elytra advance so gradually from pale rufous to black, or vice versa, there can be little doubt of the identity of the different varieties.

(longiceps) nigra, punctulata, ex pube alba subincana ; capite elongato ; prothorace canaliculato ; elytris luridis litura antica, sutura, apiceque, nigris. Long-headed Leptura, black, minutely punctured, somewhat hoary from white down; head elongated; prothorax chan- nelled; elytra lurid with an anterior blotch, the suture, and apex black. Length of the body 4 lines. Several specimens taken in Lat. 54°. and 65°. DESCRIPTION. Like the preceding species but shorter in proportion with alonger head. . Body black, punctured, hoary with rather silvery down: head as long or longer than the prothorax ; eyes pale, subtriangular ; antennz with the second, third, and fourth joints slenderer than the rest: prothorax shaped as in L. Proteus, constricted before, depressed behind, but without diverging angles, channelled but with no gibbosity on each side the channel: elytra nearly linear, very thickly punctured, dirty-yellow, with a dusky lateral blotch extending from the base beyond the middle of the elytrum, suture and subtruncated apex black ; down yellowish. Having now described all the Capricorn beetles and other Longicornia of La- treille taken in the Expedition, and being arrived at a spot whence there is a direct path to his Eupoda, I shall again retrace my steps, and call back the reader’s atten- tion to the last family of Mr. W. S. Mac Leay’s Rectocera, the Passalide, from which, as was before observed,? we may get an approach, by the Scolytide, &c. to the great tribe of Rhynchophorous beetles, or those the anterior part of whose head terminates in a rostrum or snout. A most remarkable insect, taken by Edward Bennett, Esq. in Choco, in Colom- bia, and a specimen of which may also be seen in the collection of the British Museum, may be here noticed, as supplying the first stage in the route now indi- cated. Its general figure is that of a Passalus, only more convex and cylindrical: it has the same description of mandibles but rather straighter ; a similar upper-lip; the vertex is crowned with an incurved horn as in Passalus cornutus, &c.; the = See above, p. 163. 188 NORTHERN ZOOLOGY. furrows of the elytra are similar and crenated ; and between the claws, as in the thalerophagous Lamellicorn Beetles, and some of the saprophagous is a plantula or little spurious joint, but instead of a single pseudonychium or bristle, it is furnished with ¢wo on each side.* All these circumstances prove something more than an analogical relation between this genus and Passalus, and that they may be placed near to each other in the scale of affinities, with no very wide interval between them. Phrenapates differs from the last-mentioned genus, chiefly in its tongue, the lobe of its maxilla, in its antennz without a lamellated or pectinated knob ; in having all the tibiz armed with teeth, and in its heteromerous tarsi. —- Having thus, as it should seem, discovered a link that may be connected with the Passalide, by the intervention probably of some intermediate genus,‘ we are next to look for some group, leading towards the Rhynchophorous beetles, that will approach it on the other side. Fabricius placed Sinodendrum amongst the Bostri- 3 Introd. to Ent. iii, 385, 691. In the genuine Dynastide the Plantula is very conspicuous, but instead of Pseudonychia it terminates in a pencil of stiffish hairs. I shall here give the characters of the genus alluded to in the text. * Genus Purenapates. Kirb. Labrum transverse, submembranous, subemarginate, hairy, especially at the apex. Labium nearly square, above longitudinally lacunose; at the apex emarginate in the middle with a sinus on each side. Tongue horny, linear; dilated at the base, rounded at the apex, above convex. Mandibles protended, robust, three-sided, widest at the base and excavated, toothed at the apex, and internally. Mazille one-lobed ; lobe narrow, acute, fringed with hair on the inner side. Mazillary palpi four-jointed, filiform, the three first joints subclavated, the third shorter than the rest, last joint cylindrical. Labial palpi three-jointed, filiform, two first joints subclavated, the third straight internally. curving externally, the first joint longer than the rest. Mentum three-lobed, intermediate lobe much shorter than the lateral ones, truncated. Antenne robust, eleven-jointed, joints somewhat spherical, the three last larger than the rest, so as to form an oblong knob. Body subcylindrical, naked. Head transverse, scarcely narrower than the prothorax: eyes small, prominent, subhemis- pherical: trunk isthmiated: prothorax very slightly channelled, anteriorly and posteriorly subsinuated on each side; pros- ternum dilated at the base; at the apex recurved between the arms ; mesosternum an obtuse mucro ; metasternum a rounded lobe: legs, posterior pairs distant ; thighs subcompressed linear; tibise armed with spiny teeth, with a pair of moveable spurs and a pair of fixed teeth at the apex ; four anterior tarsi five-jointed, with the four first joints very short, the last elongated and clavate ; posterior four-jointed with the first joint rather long, the two next short, the claw-joint as in the other legs ; claws single incurved; between the claws is a spurious joint furnished at the end with two pairs of bristles : scutellum triangular ; elytra slightly furrowed, furrows crenate. There is a Sierra Leone insect taken by Afzelius, and described by Gyllenhal,* under the name of Passandra sexstriata, which comes near Phrenapates, but the labium, tongue, and antenne differ. P.

Two or three specimens taken by Edward Bennett, Esq. in Choco in Colombia. The mandibles in this species are incurved at the apex, and armed with three sharpish teeth, the intermediate one being the longest ; on the innerside are two short obtuse ones, of which the posterior one is the smallest. 1 Sinodendrum cylindricum appears an intermediate insect agreeing in many characters with Phrenapates. Its antenne exhibit the knob of those of the Lucanide. * Schon. Syn. iil, append. 146, 200, ¢. vi, fi 3. ANOBIDZ. 189 chide, to which Mr. W. S. Mace Leay acknowledges it exhibits an affinity worthy of further investigation,° it exhibits likewise characters that connect it with the Lamellicorns, and Phrenapates is similarly circumstanced. ‘There are several such characters that appear occasionally in all these tribes, thus lamellated antenne are found in Phloiotribus and Sinodendrum, as well as in the Lamellicorns; the spurious joint between the claws of the tarsi is found in Bostrichus, as well as in Phrenapates and the tribe just named; all the tibize are armed with spiny teeth in Sinodendrum, Phrenapates, and some Bostrichi; the head also is armed with a horn not only in the two first, but in some species, of the last of these genera. Giving due weight to all these circumstances, I think it may be fairly deduced from them, that the Passalide by Phrenapates and Sinodendrum lead off to the Bostrichide, which are generally acknowledged to lead in their turn to the Rhyncho- phorous beetles. Having cleared, as I hope, this point, I shall now proceed to the description of the insects of the two latter tribes, taken in the Expedition. iv. XyLotrypa. Kirb. Family ANOBIDA. Latreille has placed his Ptimiores, including the present family, at a great distance from the other Lignivorous beetles, to which I agree with Mr. Stephens in think- ing they properly belong; but I regard them as forming two families at least, Ptinide and Anobide. I hesitate, however, as to their place, for they seem to occasion a disruption of affinities, if placed between the Bostrichide and Scolytide; I am therefore disposed to consider them as out of the direct line, and forming a branch from the former of these families. As there are only two species in the collection belonging to this family, I shall describe them in this place. 5 Hor. Ent. 33. 190 NORTHERN ZOOLOGY. XCIV. Genus ANOBIUM. Fab. * Elytris striatis.

Excavated Anobium, reddish brown, paler underneath, pubescent, subcylindrical; back of the prothorax elevated with an excavation in the middle; armed on each side with a tooth. Length of the body 2 lines. A pair taken in Lat. 65°. DESCRIPTION. This species very closely resembles A. striatum, of which it may be regarded as the American representative. It differs principally in having a rather large excavation in the middle of the elevated back of the prothorax, the sides of which are armed with a triangular tooth or prominence.

Prothorax anteriorly sinuated on each side with the middle lobe rounded and projecting a little over the head; sides slenderly margined; posterior angles rounded. Punctures of the elytra seem almost, but very indistinctly, arranged in rows. I am not quite clear that this is Major Gyllenhal’s C. micans. The clava of the antennz is of the same colour with the stalk, and the punctures of the elytra appear almost but not evidently arranged in rows, which leads to some suspicion that it may be the C. hispidus of that author. It is however the Ptinus villosulus of Mr. Marsham: and I think the Anobium micans of Fabricius and Paykull. SCOLYTID. 191 Family SCOLYTID.! XCVI. Genus TOMICUS. Lat. (255) 1. Tomicus pint. (Say.)

Antenne with a large rather ovate, hairy, solid compressed knob; with an elongate, clubbed scape: subglobose-pedicel ; stalk with four or five indistinct joints.” Eyes bipartite, immersed, with the lobes connected by a series of lenses.® Front in one sex excavated into a concavity, in the other plane. ° I consider those Xylotrypa as forming this family which have capitate antenne; those in which they terminate in an elongated knob of three joints, as Bostrichus, &c. I denominate Bostrichide. 7 Plate VIII, Fig. 2, a. 8 Ibid. b. 192 NORTHERN ZOOLOGY. Prothorax short, subglobose, anteriorly elevated and rough with points. Elytra substriated, unarmed at the tip in both sexes. Geoftroy having long since separated two Xylophagous genera from Dermestes Linn. under the names of Bostrichus and Scolytus,® I follow Latreille in adopting his nomenclature in preference to that of Fabricius and Herbst; the first naming the Bostrichus of Geoflroy Apate, and his Scolytus, Hylesinus ; and the last distinguishing the latter genus by the uncouth appellation of Hkkoptogaster. I have here restricted the name of Apate to those Xylotrypa which agree in their characters with Apate limbata Fab. (Dermestes domesticus Linn.) which I regard as the type of the genus. It appears intermediate between Bostrichus Geoff. and Tomicus Latr. From the former it borrows its subglobose prothorax, rough anteriorly with sharp points or denticles, and from the latter its antenne terminating in a solid compressed knob.! It differs from both in its bipartite eyes connected only by a few lenses, and by the concave forehead of one sex. (256) 1. * ApaTe sivitrata. Two-striped Apate.

Head rough with minute elevations or granules; nose terminating in a transverse ridge ; antennz testaceous with a very large knob: prothorax sub- globose, reddish, rough behind with numerous transverse rugosities ; before with sharp points or denticles: elytra with several rows of punctures, and two luteous stripes which unite at the apex of the elytrum; or perhaps it might be better to say, luteous, with two piceous stripes, one of the disk and the other of the side, but not reaching the apex: anus and legs testaceous. In the other sex the front, or rather face, is hollowed out into a concavity ; the prothorax is black anteriorly, and less rough from rugosities and points.? 9 Geoff. Ins. i, 301, 309, comp. Linn.

Prothoraz anteriorly narrower, subconstricted, not armed with elevated points or denticles. Elytra inflexed at the base, covered with minute depressed hairs, resembling little scales. This subgenus agrees with a genuine Apate in its eyes, antennae, legs, &c. but the prothorax is of a different shape, never asperated with rugosities, points, or denticles, and like Cis, the body, particularly the elytra, is covered with scale-like hairs. This little group, if placed between Tomicus and Apate, seems rather to interrupt the series of Xyloptrypa with an elevated and asperated pro- thorax ; it may perhaps be best regarded as branching off from the latter in another direction ?

Red-winged Hylurgus, black, hairy, rather glossy ; prothorax with an obsolete ridge; elytra rufous, furrowed, furrows punctured, with the dorsal interstices rough. Length of the body 3 lines. Many specimens taken in the Journey from New York to Cumberland-house, and in Lat. 65°. DESCRIPTION. Body dusky, hairy, rather glossy, punctured. Head black, confluently punctured; vertex obso- letely channelled; antennz rufous: prothorax constricted anteriorly, and dusky-rufous; base with a double slight sinus, and dorsal ridge terminating in an impression at the angle between the sinuses : elytra rufous, furrowed ; furrows punctured; interstices of the furrows rough with minute elevations, especially at the base, which is inflexed: tibie and tarsi dull-rufous; the former denticulated on one side. N. B. In some specimens the elytra and anterior part of the prothorax are piceous or nearly black; in others the elytra are testaceous, and the prothorax piceous and paler anteriorly. From Hylurgus the transit to the Rhynchophorous beetles by the lignivorous genera Cossonus, &c. is very obvious, and has been admitted by Latreille and several modern Entomologists. In the present arrangement, indeed, I have reversed that of Latreille, because, for the reasons above stated, the passage is from one branch of the Rectocera of Mac Leay by the Xylophaga to the Rhynchophora, which keeps together the great body of lignivorous Coleoptera. lo Q lo 196 NORTHERN ZOOLOGY.

Brevirostres. Linn. Family CLEONID/E. Cleonidans. CII. Genus CLEONIS. Meg. In the Introduction to Entomology, willing to retain the ancient name Curcudlio, to indicate one of the modern genera into which the immense tribe of Rhynchophora is divisible, we had considered Linné’s Curculio nebulosus, belonging to the present genus, as the type of it, but viewing the matter more attentively, it strikes me that the only group entitled to be distinguished by that ancient name, is the Curculio of Pliny and the Romans, called by us the weevil, and by the French Calendre, which Clairville, latinizing the word, has made Cafendra.> The species above described as a Calandra belongs to a different group from Curculio grana- rius, Oryza, Zee, &c. distinguished by its superior size and its triangular and very distinct scutellum. I would therefore propose calling this and its congeners, Calandra, and the granivorous ones, above noticed, Curcutio. » In his plate it 1s written Calandra, which Fabricius has adopted. Clair. Ent.

Striped Cleonis, linear, hoary from pile; rostrum obsoletely ridged; prothorax and elytra with three blackish stripes. Length of the body 33—5 lines. Several specimens taken in the Expedition. DESCRIPTION. Body narrow, black, clothed with decumbent hoary pile. Head thickly covered with hairs, but on each side from the eye to the insertion of the antenne, the hairs are less dense, which gives the appearance of a blackish stripe; rostrum thick, shorter than the prothorax, obsoletely ridged, punc- tured: prothorax obsoletely ridged, punctured with rather large scattered punctures, often concealed by the hairs, with three blackish stripes, produced as in the head by the hairs being thinner: the elytra also have three similar stripes, and are punctured in rows: the abdomen underneath appears as if dotted with black from the same cause. Family PHYLLOBIDA. Phyllobidans. CIII. Genus MACROPS. Kirb. Body oblong, winged. Rostrum shorter than the prothorax, subcylindrical, somewhat arched, having a dorsal longitudinal ridge; bed of the scape of the antennz oblique reaching from near the apex of the nostrum to the middle of the eye; antennz apical, longer than the head, eleven-jointed ; scape as long as the remainder of the antenne, incrassated at the apex, reaching the eye; two next joints longer than the subsequent ones, obconical ; the following four very short, top-shaped; the four last forming a subovate knob; eyes lateral, subimmersed, long, forming, in some measure, an isosceles triangle with the base rounded, and the vertex downwards :° prothorax subglobose; ante- pectus emarginate, sides obsoletely lobed: scutellum very minute, triangular; coleoptera oblong : thighs unarmed ; tibia armed with a very minute incurved spine or spur; tarsi not dilated, penul- timate joint bipartite. At first sight the species of this little group would be set aside as belonging to Sttona Germer, with which they possess many characters in common; a closer inspection, however, will satisfactorily prove that they belong to different genera, In the genus just named, the rostrum is shorter, thicker, and channelled; the knob of the antenne consists only of three joints, the bed of the scape turns below the eye; the eye inself is round: the antepectus is not emarginate, or lobed; the tibiae have no incurved spine. I cannot find this genus in Schénherr. 6 Plate VIII, Fig. 4, a. 200 NORTHERN ZOOLOGY. (267) 1. * Macrops MACULICOLLIs. Spotted-necked Macrops. M.

We may leave the Gonatocerous group, or circle, by an insect which exhibiting all the other characters of Schénherr’s legion of Brachyrhynchi, belongs to the Orthocerous division of that author, or Rhynchophora with straight unbroken an- tenn, but there seem to be several links wanting between it and the Brachyceride.

Length of the body 2 lines. Taken in Canada by Dr. Bigsby. DESCRIPTION. This species is nearly the transcript of A. curculionoides, for which I at first mistook it, but a closer inspection convinced me it was distinct. They agree in being black, glossy, and naked; in having a red prothorax and elytra, the latter with several rows of punctures; in having the head and rostrum more or less punctured, with curved impressed lines on each side just above the eyes, in the disk of the front; the prothorax also in both is minutely punctured, and the cubit arched and internally serrulated. They differ, however, in several respects. In A. curculionoides the head is wider in proportion, the occiput black, levigated, with a central impression ; the curved lines of the front not distinctly punctured; the stalk of the antenne rufous; the prothorax at the base is streaked with transverse linear impressions; the scutellum is nearly black, and the interstices of the rows of punctures of the elytra are irregularly punctured. In A. similis the hinder part of the head which is punctured and wrinkled, and scutellum are rufous, a transverse impression divides the occiput from the front ; the curved lines are distinctly punctured; in the front between the eyes is a wide chan- nel; the antenne are piceous; the prothorax is not streaked at the base: and the elytra between the rows of punctures are levigated.

The whole of the body is very black, except the shoulders of the elytra, which are covered by a large oblong red spot, the anterior thighs are armed with a minute tooth: the disk of the coleoptera, or elytra taken together, towards the base is depressed; and the scutellum is obversely triangular, the vertex of the triangle pointing towards the head. CVIII. * Genus APOTOMUS. Kirb. Antenne inserted in the side of the rostrum near its base, eleven-jointed; short scape and pedicel nearly equal in length, incrassated; six following joints very minute, increasing gradually in width; the three last joints large, distinct, forming an oblong knob: rostrum about the length of the head: prothorax obsoletely lobed behind: scutellum punctiform: elytra fur- rowed, abbreviated: podex uncovered: four posterior legs distant; anterior tibie straight not serrulated. This genus, the type of which is Attelabus ovatus Fabr. and Oliv. seems intermediate between Attelabus and Rhynchites. It differs from the former principally in the articulation of the stalk of the antennz, the joints of which, in Apotomus, are comparatively much more minute and shorter ; in the anterior tibie which are shorter, straighter, and not serrulated; in its shorter head, and less dilated tarsi. From Rhynchites it differs in the shortness of its rostrum with the antenne inserted at the base instead of the middle, and having the breast of the male unarmed: from both it differs in the lobed prothorax; in the elytra being obliquely abbreviated internally both at the base and apex; in their furrowed surface; in its naked podex; and, which is a strong character, in having the four posterior legs distant from each other. In its lobed prothorax, it agrees with Rhinobatus, Rhynocyllus, Eurhinus, Illiger, &c.: it is worthy of observation, that in this latter genus and Centrinus, the four posterior legs are likewise distant; and that the males in Centrinus have an armed prothorax like Attelabus.

Taken in Canada by Dr. Bigsby. I have also received a specimen probably taken in New England by Professor Peck, from my friend the Rev. T. Brown, rector of Hemingston, Suffolk; and another from Massachusets from Dr. T. Harris, Jun. DESCRIPTION. Body obscure, bronzed. Head impressed posteriorly between the eyes; rhinarium, antenne, and an elevated space adjoining the eyes anteriorly, rufous; nose indistinctly punctured: prothorax very finely and concentrically scored, with some scattered indistinct punctures; posteriorly considerably elevated: elevation bifid; behind this elevation the prothorax is producted and emarginate: scutellum obtriangular: elytra tuberculated with several acute, compressed tubercles, the anterior ones cari- nated ; interstices with some scattered deep punctures: space between the four posterior legs punc- tured with large shallow punctures. X. PHYLLOPHAGA. Kirb. i. Cyciica. Latr. It appears to me that no very wide interval separates the Anthribide from the Cyclica of Latreille, the former tribe have lost the conical palpi, thus receding from one great character of the Rhynchophorous beetles ; their maxilla is also different and distinctly bilobed, approaching more nearly to that of the Cyclica—many forms however still intervene between them. On the above account, I have transposed Latreille’s two sections of Eupoda and Cyclica. 208 NORTHERN ZOOLOGY. Family CRYPTOCEPHALID/A. Cryptocephalidans. CXI. Genus CRYPTOCEPHALUS. Fab.

Nose with a bilobed reddish-yellow spot at the apex; front with a yellow curvilinear spot adjoining the eyes on their inner side; between the eyes behind is a pair of round impressions, and a longitudinal intermediate abbreviated channel; antenne mutilated in the specimen, but what remains oF them is reddish-yellow : prothorax levigated, but sprinkled with very minute and slight punctures, visible only under a powerful magnifier; behind with a slight sinus on each side: scutellum levigated and elevated posteriorly: elytra deeply punctured with the punctures arranged in rows, the sixth row from the suture is interrupted, and in the interstices on each side of it are some irregular punctures, the intermediate rows do not reach the apex; a luteous band, abbre- viated next the suture and growing gradually wider till it reaches the lateral margin, and an irregular spot at the apex of the same colour, distinguish the elytra. Fabricius describes his C. notatus in so Tae words that it admits of some doubt Ghether his insect is synonymous with Dr. Bigsby’s here characterized. The spots at the apex can scarcely be deno- minated puncta, but as he occasionally designates a large spot by this term, and both insects are from North America, for the present it may be allowed to stand under the above name. CRYPTOCEPHALID. 209 CXII. Genus EUMOLPUS. Klug. This genus may be further resolved into two subgenera distinguished by the absence or presence of a lateral prothoracic margin. ‘The former hairy, without much gloss, and approaching nearest to Cryptocephalus, and the latter naked, ex- tremely brilliant, and receding from that genus towards the Chrysomelide. The first I shall denominate d4dovus (Inglorious), the last Endoxus (Glorious). E. Vitis may be regarded as the type of the former, and E. ignitus of the latter subgenus. xxiii. * Subgenus Apoxus. Kirb. Labrum subtransverse, entire. Palpi (maxillary) with the two last joints much incrassated, the penultimate obconical, and last conical or subovate. Antenne with the pedicel as long as the third joint, the last joint apparently consisting of two joints. Body not glossy, hairy. Nose with a sinus taken out: prothorax very convex and almost hemis- pherical, with the sides producted and emarginate. In Endoxus the labrum is emarginate, the prothorax transverse, not so convex, sides margined and not producted; and the antenne have the pedicel, or second joint much shorter than the third, and the last joint wears less the appearance of articulation.

Both Geoffroy and Fabricius complain of the ravages committed by this little species upon the vine in Europe, and probably it is equally destructive to those of America. Family CHRYSOMELIDAE. Chrysomelidans. This family, even as it stands in Latreille’s last work, (Crustace’s, drachnides, et Insectes) will admit of further subdivision, assuming for characters, the antenne, palpi, eyes, and prosternum. If we take Chrysomela goettingensis for the type of the genuine Chrysomele, we may arrange under it all those of Latreille in which the punctures of the elytra are scattered or not arranged in rows. | CXIII.

The type and variety C taken in Canada by Dr. Bigsby. Variety B in Nova Scotia by Dr. Mac Culloch. DESCRIPTION. Body oblong, black-green, naked, glossy, convex, punctured with scattered punctures. Palpi, antenne, rhinarium, and legs rufous; labrum hairy: prothorax with the punctures at the sides more numerous than those on the disk: elytra pallid, with a longitudinal stripe at the suture with three diverging obsolete branches, and several irregular spots; one at the shoulders larger than the rest and as it were broken, or obtusangular, all of a dark green: the elytra are grossly punctured with scattered punctures, but next the suture the punctures are disposed in two rows, the sutural one ra ald CHRYSOMELIDZ. 211 extending from the base to near the apex, where it becomes confluent with the second, both diverg- ing towards the base and surrounding the upper branch of the sutural stripe; there is a fourth series of punctures at a little distance from the lateral margin, and the interstice between them is impunctured ; epipleura dark-green. N.B. The two lower branches of the above stripe are surrounded by a common series of punctures. Variety B. Smaller, green-bronzed, green spots of the elytra more numerous, epipleura pallid. C. Sutural stripe with only one branch, the two lower ones forming separate spots ; epipleura pallid. This varying species may be known from the succeeding ones by the green colour of its body ; all the varieties are distinguished by the obtusangular spot at the shoulders of the elytra: the varying number of green spots on these organs is produced by the separation of some of the irregular ones into distinct ones, and the lower branches of the sutural stripe doing the same. Variety C comes nearest to that figured by De Geer and Olivier. (281) 2. * CHRYSOMELA CONFINIS. Neighbouring Chrysomela. C. (confinis) eneo-viridis, punctata ; antennis, palpis, pedibusque ferrugineis ; elytris rufescentibus, margine laterali, vittaque flexuosa discoidali pallidis, lineis insuper flexuosis, maculisque irregularibus, eneo-vividibus, elevatisque. Neighbouring Chrysomela, bronzed-green, punctured ; antenne, palpi, and legs ferruginous ; elytra rufescent with the late- ral margin and a flexuose stripe of the disk pallid; sides with flexuose lines and irregular spots of bronzed-green and elevated. Length of the body 44 lines. A single specimen taken in Nova Scotia by Capt. Hall. DESCRIPTION. Nearly related to the preceding species. Body oblong, obscurely bronzed-green, grossly punc- tured. Palpi, antenna, legs, and rhinarium ferruginous: punctures of the prothorax scattered in masses, with the interstices very minutely punctured: scutellum bronzed: elytra reddish with a discoidal flexuose irregular pale stripe dilated at the base and towards the apex; there are also two flexuose dark-green discoidal stripes in the disk, the exterior one nearly reaching the base and the interior approaching nearer to the apex, between these towards the base is a single oblong green spot, and outside them are many irregular ones of the same colour; all these spots and stripes are convex and mostly circumscribed by punctures; there is a double series of punctures diverging towards the base; and an oblique abbreviated one between these and the scutellum, as in many Harpalide, &c.; the interstice between the double series is green at the base. There is a lateral series of punctures also as in C. Philadelphica. to & tw) 912 NORTHERN ZOOLOGY. (282) 3. * CurysoMeELA Bicspyana. Bigsby’s Chrysomela. C.

Bigsby’s Chrysomela, green, palpi, antenne, and legs rufous; anterior margin and sides of the prothorax, reddish ; elytra pale-red, with a sutural stripe, a humeral broken bilobed spot, and several dots black or dark-green. Length of the body 4 lines. A single female specimen taken in Canada by Dr. Bigsby. DESCRIPTION. Colour and sculpture of the body like those of the preceding species, from which C. Bigsbyana differs principally in having the sides and anterior margin of the prothorax reddish-yellow: the elytra are of the same colour, but the suture itself, especially at the base, a stripe parallel to it, a large humeral bilobed spot, the interior lobe of which is obtusangular or broken, and several irregular dots and spots on the elytra are black-green.

Body, head, antenne, and legs ferruginous. _Prothorax pale-yellow, with two posterior triangular ferruginous spots with a dot of the same colour between them; the punctures of the prothorax are more numerous and smaller than in C. Philadelphica, &c.; elytra yellowish-white; suture and a confluent stripe circumscribed with the double series of punctures, diverging towards the base of the elytra, ferruginous; surface covered with irregular greenish dots and short lines, as in the pre- ceding species, a row of punctures marks the exterior side of the elytra, the interstice between it and the margin is immaculate and impunctured, the rest of the elytrum being thickly covered with scattered minute punctures.

(clivicollis) violacea ; elytris rufis maculis tribus difformibus suturaque violaceis ; femoribus anticis bidentatis ; prothoracis disco valde elevato. © iill-necked Chrysomela, violaceous ; elytra red with three differently shaped spots, and the suture violaceous; anterior thighs bidentate ; disk of the prothorax very much elevated. Length of the body 44 lines. A single specimen taken in Canada by Dr. Bigsby. DESCRIPTION. Body between oblong and hemispherical, violet. Head punctured; labrum without punctures : prothorax elevated in the centre to an obtuse peak, from the summit of which descend several con- centric channels which run nearly to the margin, the interstices of which are punctured: scutellum violet with a green tint: elytra reddish, punctured, punctures scattered with some tendency to arrange into rows; three large dark violet spots distinguish the elytra, the first upon the shoulders subtri- angular with the vertex truncated, the second near the apex bilobed, the third at the base forming with that on the other elytrum a large cruciform spot; suture violet: anterior thighs armed with two stout teeth. This singular species in its form and the markings of its elytra seems to make some approach to the Coccinellide, but it exhibits all the characters of a genuine Chrysomela ; should more species be found agreeing with it in the remarkable peak of the prothorax and teeth of the fore thighs, it might be regarded as forming a subgenus. xxiv. * Subgenus PuyroprEcta.

A single specimen taken in the Expedition. 214 NORTHERN ZOOLOGY. Chrysomela 10-punctata B. (Linn. Syst. Nat. ii, 590, 32) is by many authors referred to as synonymous with C. rufipes De Geer, but it appears from the descrip- tion of that variety in the first edition of the Fauna Suecica (p. 1354) that it had black legs, and therefore belongs to C. nigripes De Geer. By Linné’s considering the black-legged species as his variety 8, it seems not improbable that « had red legs. DESCRIPTION. The American differs a little from the British specimens. In the first place it is scarcely half the size, not only the mouth but the space before and between the eyes is rufous, only the vertex and occiput being black: the black spot of the prothorax, instead of consisting of two distinct spots connected only at their base, is only divided at its apex into two lobes, and the spots of the elytra, though similarly arranged, are less distinct: they agree in having the body underneath, except the rufous anus, black; and the legs rufous. CXIV. * Genus PHAXDON. Meg. Labrum transverse, scarcely notched. Pailpi (maxillary) four-jointed ; first joint minute; second longer than the rest incrassated at the apex; third as large, or larger than the fourth, triangular; fourth rather conical, truncated. Antenne scape incrassated ; pedicel shorter than the following joints; third, fourth, and fifth longer and obconical ; five next triangular, larger than the antecedent ones and terminated by an ovate acute joint. Body oblong; eyes transverse, oblong; prothorax transverse; scutellum rounded at the apex; elytra rather soft, oblong, with punctures not arranged in rows. N. B. This genus is principally distinguished from Chrysomela by the last joint of the palpi being smaller than the preceding one and of a different shape.? 286 1. Poapon Aponipis.

Adonidis. CHRYSOMELID. 215 DESCRIPTION. Body black, punctured, sprinkled underneath with cinereous hairs. Vertex rufous with an occipital black spot: prothorax reddish-yellow, with a large discoidal black spot reaching from base to apex and constricted anteriorly; on each side also there is a round black dot: scutellum black, impunctured: elytra reddish-yellow, thickly punctured with scattered punctures; suture black except at the base; a black discoidal stripe or blotch reaching neither to the base nor the apex, anteriorly obliquely truncated and posteriorly acute, also distinguishes these organs. Variety B. With the discoidal stripe acute at each extremity and smaller. C. With the discoidal stripe evanescent. Mr. Stephens, in his Catalogue of British Insects, has placed this insect in his section of Chrys- omela with securiform palpi, and elytra with punctures in rows. He was probably led to this by Mr. Curtis’s figure, in which the palpi, for the reasons lately assigned, are securiform, and the punctures dispersed in rows, though Mr. Curtis describes the elytra as ‘somewhat irregularly punctured.” In the American specimens, and Panzer’s figure, there is not the least appearance of rows.

Ent. v, 93, 673, 6, t. i, f. 6. Length of the body 33 lines. Taken in Canada by Dr. Bigsby. DESCRIPTION. Very near related to Galleruca quadrimaculata . Body long, glossy, reddish-yellow: posterior part of the head black, a cross impressed between the eyes; antennz dusky with the four first joints rufescent : prothorax impunctured, transversely subimpressed behind, sides margined: elytra very minutely and lightly punctured with punctures just visible under a good lens; at the base of each elytrum nearest the suture is a roundish black spot, and another large oblong one extends from above the middle towards the apex: posterior thighs a little incrassated ; tarsi dusky especially at the apex; medipectus and postpectus black. This species forms a link between the Halticide and Gallerucide : it is clearly the Altica qua- drimaculata of Olivier, and may be regarded as the American representative of Galleruca quadri- maculata I. from which it differs principally in the colour of its antenne and its incrassated posterior thighs.

Linn. xxvi. * Subgenus Anopuitis. Kirb. Body without spines; third joint of the antenne not much longer than the second: scape un- armed. In the genuine Hispe, of wHich H. atra may be regarded as the type, the structure of the antenne is very different from that both of the other spinose ones, and of those that are without spines; the four first joints terminating externally in a spine, that of the scape being longer than the rest and not being a prolongation of the external angle. In H. erinacea, and several other American species, the third joint is very long, in Anoplitis it is scarcely longer than the second, as in Hispa atra, but the four first joints are without the spine. We have therefore here types of three subdivisions, viz. Hispa proper, Anoplitis, and Lobacantha, as I would denominate H. eri- nacea and affinities, from the lobes crowned with spines which project from the elytra. (308) 1. Hispa (Anoplitis) picovor.

Length of the body 2 lines. A single specimen taken in Lat. 65°. 239 NORTHERN ZOOLOGY. DESCRIPTION. Body black. Mouth and its organs and antenne reddish ; prothorax flesh-coloured with two large subquadrangular black spots, separated by a narrow flesh-coloured stripe, which occupy almost all the disk: elytra flesh-coloured, taken together with eleven roundish rather large black spots, three of which are common to both elytra, viz. 3, 4, 3, 1, the common spot at the apex is transverse: legs black with the base of the thighs and tibia, tarsi, sides of the abdomen, and anus testaceous. This species seems to come near C. borealis of Thunberg, but it differs in colour and the number and disposition of the spots. XU. HETEROMERA. Geoff. Lat. I have deferred the description of the Heteromera till now, because one of that subdivision, Meloe, appears evidently to be one of the links that connect the Coleop- tera with the Orthoptera; yet, as was long since observed, the predaceous genus Manticora seems to present some signs of a leading off towards, to the first tribe of the Heteromera the Melasoma of Latreille. i.

Body dull-black, oblong, naked. Head minutely punctured ; antenne shorter than the prothorax : prothorax widest in the middle, subquadrangular with the sides rounded, minutely but not very thickly punctured, with some slight impressions in the disk: scutellum short, wide, rounded at the apex: elytra with six elevated granulated lines alternately more pronounced, besides the suture and marginal one separating the epipleura, which meet just above the apex: epipleura granulated: pos- terior legs much longer than the four anterior. Mr. Say says of his P. rotunda, that it was the first of that genus found on the New Continent ; that above described furnishes therefore a valuable addition to the American insect Fauna. Africa appears to be the metropolis of the genus, though several species have been found in Russian Tartary. Family TENEBRIONIDAE. Tenebrionidans. CXXIV. Genus UPIS. Fab. (317) 1. Upts ceramBorpEs.

Head nearly round, depressed, porrected; eyes lateral, kidney-shaped; nose circumscribed by the segment of a circle ; antennz a little shorter than the prothorax, joints obconical, four last lentile-shaped: prothorax a little wider than the head, oblong with rounded sides: scutellum rounded at the apex: elytra taken together wider than the prothorax, a little dilated beyond the middle, and then sloping to the apex, which is acute; very unequal with numerous irregular deep impressions and rugosities, variously separated by a number of elevated lines or obtuse ridges running confusedly in various directions : legs long; thighs incras- sated ; tibize and tarsi slender. This insect is stated by Fabricius to inhabit a particular kind of Boletus (B. fomentarius L.) : Gyllenhal says that it inhabits perennial fungi growing upon trees, particularly of the genus Betula. It has not yet been discovered in Britain; but if attention be directed to these fungi it may very likely at length make its appearance in the list of British insects. 2H 234 NORTHERN ZOOLOGY. CXXV.

Taken in Nova Scotia by Capt. Hall. DESCRIPTION. Body linear-oblong, pollinose. Head brown-black, subtriangular; labrum ciliated with yellow hairs; antenne black-piceous, last joint smaller than the two antecedent ones, which are bigger than the rest: prothorax brown-black, obcordate with a larger anterior sinus for the head; surface flat, uneven behind from five obtuse ridges, the lateral ones abbreviated, and before from several rounded tubercles: scutellum minute: elytra embrowned with a yellowish tint from lutose scales, anteriorly BOLITOPHAGIDE—HELOPID ©. 37 with three obtuse ridges; the interior one very short; the intermediate one discoidal, abbreviated at each end; and the exterior one reaching from the base to the apical tubercles, of which there are two much elevated, the interior one being the largest and highest; in the interstices there are four rows of deep impressions: the sides of the antepectus are verrucose: the abdomen is black-brown with lutose sides; the disk is longitudinally, densely, and thickly wrinkled, and the sides are verrucose : legs black-brown. This species differs from the preceding one in the form of the thorax and the clava of the antenne, and ought perhaps-to form a subgenus. iii. STENELYTRA. Family HELOPIDZE. Helopidans. CXXVIII.

Canada Meracantha, black-bronzed, naked, glossy, punctured ; elytra furrowed, furrows punctured ; interstices minutely punctured. Length of the body 6 lines. Taken in Canada by Dr. Bigsby. DESCRIPTION. Body black-bronzed, naked, glossy, punctured: on the upper side of the body the colour is more metallic. Head and prothorax confluently punctured, two last joints of the antenne pale from hairs: elytra slightly furrowed, the sutural and the marginal furrows meeting at the apex and including the rest; furrows punctured; interstices very minutely and thinly punctured: sides of the abdomen longitudinally wrinkled: tooth of the shoulder short and wide, placed a little above the middle.

One-coloured Cantharis, all black, hoary from pile; prothorax channelled: antenne with the two first joints very long. Length of the body 7 lines. Taken in Canada by Dr. Bigsby. DESCRIPTION. Body black, hoary from numerous decumbent white hairs: antenna subsetaceous, a little longer than the prothorax; two first joints very long, the first curved and nearly twice the length of the second; and the second as long as the three following ones together: prothorax rather bell-shaped, channelled: wings embrowned. This species seems to come near to the Lytta immaculata of Say,‘ but the relative lengths of the joints of the antenne differ, the palpi of our insect are black, and it is much smaller. CXXXIV. Genus MELOE. Linn. This genus appears to be one of the stepping stones to the Orthoptera, which is proved not only by its galeate maxille, but, by its elytra lapping over each other, and its vertical and often inflexed head, in this respect resembling the Blattina. 4 Journ.

Nearly related to Meloe violacea, but very much smaller. Body violet-coloured. Head with scattered but not large punctures; front between the antenne transversely and obtusely elevated ; antenne irregular: prothorax not much narrower than the head, anteriorly rounded, posteriorly narrower and emarginate, towards the base with a deepish impression, with several scattered but not large punctures, and two little transverse oblique crescents formed of punctures: elytra wrinkled : outer claws and spurs rufo-piceous, inner claws paler.

A single specimen taken in Lat. 65°. DESCRIPTION. Extremely similar to the preceding species, but the body is all black with no tint of violet, except the base of the antenne below the band and the tibie and tarsi: the head and prothorax are more thickly punctured, and the claws and spurs are ferruginous. XI. MALACODERMA. Lat. The Malacoderma of Latreille by the soft substance of their elytra, and their reticulations in some species of Lycus, seem to make an approach to the Orthoptera. ‘They appear to branch off from the Elateridans by Campylus to Cebrio, and there- fore we must now be regarded as retracing our steps to take a fresh route from that family in a new direction towards the Orthoptera.

Pit-necked Dasytes, black-blue, somewhat hairy: head and prothorax punctured ; the latter with two anterior impressions. Length of the body 23 lines. A single specimen taken in the Journey from New York to Cumberland-house. DESCRIPTION. Body somewhat hairy, underneath black and glossy; above with a blue tint. Head glossy, punctured with largish scattered punctures; front with two impressions: prothorax nearly square, with the sides a little curved, punctured at the head, with a pair of transverse anterior impressions ; sides and base margined, margin reflexed: elytra less glossy than the rest of the body, minutely, but not conspicuously, punctured. This species answers in almost every respect to Major Gyllenhal’s description of Dasytes ceru- leus, but as he does not notice the impressions in the prothorax, which so minute a describer would scarcely have overlooked, I apprehend it as a distinct species. What we have in England under the name of D. ceruleus is the Lagria viridis of Rossi, a fine green insect, first taken I believe on the Sussex coast by Sir W. T. Hooker. It differs from D. ceruleus not only in its colour, but also by having the prothorax much more thickly punctured. Family CLERIDZA. Cleridans. CXXXVI. Genus NECROBIA. Oliv. (332) 1. Necropia viovacea.

Punctures on the head and prothorax nearly confluent and larger than those of the underside of the body; antennz black, last joint sub- quadrangular: sides of the prothorax obtusangular: scutellum black : longer punctures of the anterior half of the elytra arranged in rows with the interstices minutely punctured, the rows then disappear, and the whole of the apex is indiscriminately and minutely punctured: legs black with a tint of brown. On the continent this insect has been universally confounded with the Clerus violaceus of Mr. Marsham, which Mr. Stephens considers as a distinct genus and as synonymous with Corynetes violaceus of Paykull: but as the latter has evidently in his description of the palpi had in view those of Necrobia, and assigns the habitat of that genus to his Corynetes, it scems clear that it is synonymous with Olivier’s genus. The latter author has evidently confounded the two as well as Latreille. Thinking those found in carrion synonymous with those creeping about the windows of our houses early in the year, he took his figure from one of the latter, as is evident from his sketch of the palpi and antennez which are not those of Necrobia, but belong to Corynetes. Linné him- self appears to have confounded these two insects; for his short description belongs rather to Corynetes violaceus than to Necrobia violacea; the character, thorax villosus, belonging more to the former than to the latter, the prothorax of which is much less hairy; but the terms in which he describes its habitat in the Systema Natura, cadaveribus inhians, indicates the latter. I believe I was the first who pointed out the difference between the two to the late Mr. Marsham, and the trivial name he adopted, Clerus Quadra, was suggested by me. There seems to be some tendency in this genus to Cryptophagus, &c. CXXXVII. Genus THANASIMUS. Lat. (333) 1. * THANASIMUS ABDOMINALIS. Abdominal Thanasimus. T.

In Canada by Dr. Bigsby. DESCRIPTION. Body oblong, pubescent, brown-black. Nose and mouth elongated: prothorax nearly semicir- cular, disk elevated ; a rose-coloured arched streak dilated and yellower anteriorly adjoins the elevated part on each side: elytra obsoletely carinated, most numerously and minutely punctured. Linné gives this as a native of Finland and Russia, on the authority of Uddmann, but it has not since been found there. Perhaps Uddmann might have mistaken American specimens for European. The Lampyride seem to lead towards the Blattina, 1 have therefore placed them last in the series of insects with soft elytra, as connected with the Orthoptera in a different point from Medoe. Mr. Stephens has placed the Brachelytra next to the Dermaptera, and not without some appearance of reason, but their connection with Necrophorus and consequently with the Necrophaga,° is so much more striking that I do not see how they can be displaced without violating nature. 5 See above, p. 82—86. aK i) or S NORTHERN ZOOLOGY.

I at first regarded this insect as a variety of Cimbex Vitelline, but the colour of the antenne and legs differs; and what Linné meant by the words dabio caret, is not clear—but as the upper lip is very conspicuous, though entirely black, it cannot be supposed to agree in that respect; unless we interpret his words as meaning that it had not a white lip like C. Amerina, the next species, which seems not very probable. St. Fargeau, in his Monograph on the Saw-flies ( Tenthredinete,) has a Cimbex Vitelline, but his description does not agree with that of Linne. (353) 2. Tricutosoma Lucorum. (Leach.)

Head something wider than the trunk, subtriangular: antenne piceous with the scape black ; wings cast in all the specimens; scale vertical between the trunk and abdo- men, sloping to a thin edge upwards, where it is very slightly emarginate: abdomen oblong, subey- lindrical, minutely punctured with the punctures piliforous; hairs decumbent with those of the margin of the segments and the anus, longer; margin of both abdominal and ventral segments membranous, membrane reddish; base of the three intermediate segments not punctured. This species a good deal resembles the Formica herculanea of Linne (F. ligniperda Latr.) but it is proportionably more narrow, and entirely black save the legs and upper portion of the antenne. I at first took it for a variety of F. pubescens of Latreille,! but in his description of that species, he makes no mention of the punctures of the abdomen, nor of the rufescent membranous margin of the abdominal segments, circumstances also which distinguish it from /. pennsylvanica of De Geer, and which, from the figure of that author, is evidently a much smaller insect.?

Head and trunk thickly clothed with long woolly down of a grayish colour; face with three yellow spots placed in a transverse line behind the antenne, the two lateral ones subtriangular, the intermediate one subquadrangular, with a reddish cloud on its disk ; the nose below the antennz is yellow, inclining to red round the margin; it has also three black dots placed in a triangle in the disk, the two lower ones being very minute; the vertex of the nose is also black ; the mandibles are yellow with black tips; on the outside the orbit of the eyes is reddish-yellow : the trunk is black underneath; above the posterior upper margin of the collar, the tegule which cover the base of the wings, and a triangular spot underneath them, are yellow; on the metathorax and scutellum are six yellow spots placed in a double series, the upper and lower pairs being subtriangular, and the intermediate pair crescent-shaped: the thighs are black at the base, but their apex, and the rest of the leg, and a small triangular spot on the inner side of the four posterior trochanters, are yellow; the wings are yellowish red with red nervures: the abdomen, except at the base, is less hairy than the rest of the body; it is yellow with all the segments, black at the base; though the blackness in the terminal ones is chiefly concealed by the antecedent segments; in all in the middle it projects into a triangle; the four intermediate ones have also each a round-headed small black spot, the connection of which with the blackness of the base is inter- rupted in the second segment; on the under side of the abdomen the base of the segments is black, and the intermediate ones have each a pair of rather crescent-shaped black spots not connected with the blackness of the base. From this minute description, it will be seen that the American specimen which is very small, differs in several respects from the European wasps of the common species, especially the spots on the vertex, and the six, instead of four spots, on the scutellum and metathorax: but as it exhibits nearly all the other characters ascribed by Linne to his V. vulgaris, I have judged it best, as there was only a single specimen, to consider it as forming a variety rather than a species. I imagine Aristotle’s two species of wasp, one of which forms its nest in the oaks of the mountains, and the other underground, are the Vespa crabro and vulgaris of Linne; Pliny mentions his Vespe and Crabrones, the former as building their nest on high, and the latter as selecting caverns and sub- terraneous cavities; whence it seems probable that the last is the real V. vulgaris. He mentions in the same chapter Vespe which are called Jchneumones, which carry spiders into their nest, from which circumstance it seems probable that these belonged to the modern genus Pompilus or the Spider- wasp.

This little insect is so extremely like Halictus levis,” that at first I regarded it merely as a variety of that species, but upon a closer inspection they appear to me distinct. In H. crassicornis the antenne are proportionally more robust, but the principal difference lies in the sculpture of the thorax. In H. levis that part is visibly punctured with scattered punctures, but in the insect I am describing, under a common lens, the punctures are scarcely discernible, but under a higher power, besides a slight channel drawn longitudinally, innumerable very minute punctures appear. In the former also the stigma of the upper wings is piceous, while in the latter it is testaceous. In other respects they are perfectly similar. CLIX. Genus ANDRENA. Fab. (371) 1. * ANDRENA IMPUNCTA.

Their labrum is obtusangular; their mandibles obliquely truncated; their posterior tibie and plante are with- out any apparatus for carrying and kneading the pollen ; their abdomen is inflexed and the last ventral segment projects on each side so as to form an angle; all characters not to be found in the other Bombi, no writer seems to have noticed this tribe, unless Klug’s Péilopus be synonymous with it, which I have not the means of ascertaining, if not already named I would call the genus by Jurine’s name Bremus.

We are now arrived at the second great subdivision of the class Insecta, those that take their food by suction, which may be regarded as forming a series of Orders parallel with those of the first.? Under this view I shall, with Dr. Leach and Mr. Stephens, consider the Hemip- tera of Linné as restricted by Latreille, as really forming two Orders, analogous to the two first Orders of the Mandibulata, the Coleoptera, and the Orthoptera, call- ing, with them, the first of them by the old appellation Hemiptera, and the second Homoptera.

Very near P. oleracea, and probably its American representative. Body black, a little bronzed ; grossly and thickly punctured, the punctures on the upper surface the deepest. Head subtrape- zoidal; promuscis pale in the middle; antenne longer than the head: prothorax wider than long, with the lateral angles obtuse; signed with a sanguine cross, the arms of which extend from angle to angle; lateral margin, as well as that of the hemelytra and abdomen, white: scutellum longer than the thorax, obtuse with a subtriangular sanguine spot on each side near the apex : penultimate ventral segment of the abdomen margined with white : membrane white. The specimens collected in the Expedition differ from the description of Fabricius in having the margin of the abdomen and that of the elytra white instead of sanguineous; but as the sexes of P. oleracea differ in the colour of their spots, this may be a sexual distinction. I received a speci- men from Dr. Mac Culloch which agreed with the Fabrician description. In one specimen the markings and spots of the elytra and scutellum are very pale. 2 See Introd. to Ent. iv, 421—25. DINED 276 NORTHERN ZOOLOGY. (384) 2. * PENTATOMA VARIEGATA. Variegated Pentatoma.

Ridged Corixa, with the body underneath, head, and legs pale-yellow ; the hind-head posteriorly in the middle transversely, and the vertex longitudinally, obtusangular ; prothorax ridged, brownish-black, transversely streaked with yellow- ish; elytra brownish-black sprinkled with yellowish. Length of the body 4 lines. Two specimens taken with the preceding species. DESCRIPTION. This species appears to come very near to Geoffroy’s Corise,’ which is evidently not C. striata ; and also to C. stagnalis of Dr. Leach ;8 but as neither of these authors mention the ridge of the thorax, which is conspicuous, it appears to be distinct. Body yellow underneath, embrowned at the insertion of the legs. Head yellow; front broad and flat ; labrum transversely tricarinate ; occiput obtusangular ; vertex with an obsolete longitudinal ridge issuing from the angle of the occiput : prothorax with a longitudinal intermediate ridge, transversely streaked with yellow and brownish- black: hemelytra sprinkled, and towards the base almost streaked, with black and yellow. In other respects this species resembles C. striata. (398) 3. * Corrxa pLanirrons. Flat-fronted Corixa. C.

Flat-fronted Corixa, underneath black, with the sides spotted with pale-yellow; occiput obtusangular in the middle; front blunt ; prothorax carinated, brownish-black, transversely streaked with pale yellow ; hemelytra brownish-black sprinkled with yellow. Length of the body 4 lines. Two specimens taken with the preceding. p p g DESCRIPTION. This species differs from the preceding in having the under side of the body black, with two pale spots on each side of the breast, and the anal half of the abdomen pale-yellow. ‘The head is yellow, the vertex is ridged longitudinally and separated from the front by a transverse curvilinear ridge; and from which the anterior part of the face is inflexed, plane or slightly concave ; in other respects this species exhibits exactly the same characters with C. carinata. They may perhaps be sexual varieties. 7 Ins. i, 478, 1, t. ix, f. 7. 8 Linn. Trans. xii, 16. NOTONECTIDA:—CERCOPID. 285 Family NOTONECTIDE. Notonectidans. CLXXIV. Genus NOTONECTA. Linn.

Expansion of the wings 33 inches. Taken in Canada by Dr. Bigsby. DESCRIPTION. Body yellow. Head above black, below tufted with yellow: trunk and abdomen striped with black and yellow: wings yellow; primaries with five abbreviated black subangular bands; the two inner ones being common to both wings, the innermost of these bands is marginal and its lower attenuated extremity converges with that of the penultimate band, reckoning from the tip; the anterior margin of the primary wings is edged with black, with yellow scales intermixed, and two longitudinal yellow streaks between the middle and the apex; the posterior margin has a broad black stripe with an articular? yellow band; in the secondary wings the discoidal basilar area is dis- tinguished by a black streak at the apex; the posterior margin has a broad black band with a double transverse series of crescents, each series consisting of four spots, the internal series being bluish, and the external yellow; there is besides an orange spot at the anal angle, and another at the external margin; this margin is indented, with the concavities fringed with yellow; the angle between the fourth and fifth indentures projects into a short tail; the underside of the wings is yellow, but paler than the upperside; there are also the five black bands: the posterior margin of the primary wings has an interior ash-coloured band and exterior yellow one, included between three narrow black ones: the underside of the secondary wings is not very different from the upper, except that the posterior margin is not nearly so black; and at the anal angle there is a spurious ocellus consisting of a black semicircle, a blue crescent, a black, and lastly an orange transverse spot. The legs of this species are black, as are also the nervures of both wings. Fabricius says that this species is thrice the size of P. Machaon, but the specimens I received, of which there were several, were of the same size. In Mouftet’s figure, referred to by Ray, which appears to belong to the insect here described, the expansion of the wings is eight inches, but his imagination has evidently been employed in drawing that figure, which is represented with falcated primary wings. Probably it was drawn from a mutilated specimen. He has made the blue spots of the secondary wings circular, looked at in certain lights they appear so. Probably those in the warmer parts of America may be larger than the northern ones. 9 Introd. to Ent. iv, 297, 39, c. to GO NI COLIADZ. Family COLIADZE. Coliadans. CLXXVII. Genus COLIAS. Fab.

DESCRIPTION. 3 Antenne rose-coloured with the club somewhat embrowned : primary wings above saffron-coloured with a broad, deep-brown margin, a little indented internally with the nervures, especially those next the apex, and the fringe, pale yellow; a black oblong spot marks the disk nearer the anterior than the posterior margin; anterior margin paler than the rest of the wing; underneath this wing is paler, the black discoidal submarginal spot has a minute white pupil, and there is a series of about six black spots increasing in size as they approach the interior margin parallel to the posterior one ; the three first of these little spots are very indistinct: the secondary wing is also saffron-coloured and has usually a spot of a deeper colour in the disk ; the margin is also deep-brown, the brown colour terminating in a point short of the anal angle; parallel with the abdomen both wings are embrowned; beneath this wing is of the same colour with the primary, and has a series of indistinct black spots parallel with the margin; in the middle of this side of the wing is a sesquialterous compound eyelet,! the exterior circle or atmosphere? of which is composed of rusty brown scattered scales, which to form the iris are more condensed, while the pupil is formed of silvery ones. Variety B. With the dark brown marginal band of the primary wings rather narrower, and the lesser eyelet of the under side of the secondary one without a silvery pupil. C.

The American specimens of C. Hdusa seem to vary from the English as described by Mr. Stephens, in having the black discoidal spot on the underside of the primary wings ocellated, and from that described by Latreille,? in having the series of marginal spots on the underside of the secondaries blind. In the two varieties of the male above described, the passage to a simple eyelet on that wing from the sesquialterous one, is by the disappearance of the silvery pupil in B. CLXXVIII. Genus PONTIA.

Palpi brown on the upper and pale on the under side; an- tenne internally rufous, externally white, but each joint is black at the tip; knob black, tipped with pale: wings subdentated, brown-black, silky: primaries with an oblique subangular mesal orange band, incurved at the lower extremity; between this band and the apex are several white spots and dots; in the posterior margin of these wings is a sinus, and the fringe is alternately black and white, so as to form white crescents; underneath, at the base, the costa is alternately barred with blue-gray and black; the transverse band is more red, at the costa it is tipped with white, and at the anal angle with pale-yellow; between it and the base are two red streaks, the inner one branching from the band; beneath these is an indistinct eyelet with a black pupil and gray iris; above the band near the costa is an irregular angular eyelet, or two blue lines confluent at each extremity and including a black islet, then follow the white spots of the upper side but less distinct and near the apex three imperfect eyelets: the secondaries have a marginal broad orange band which almost unites with the band of the primaries, it is marked with four black dots between the nervures and at the anal angle is a double eyelet, with a black iris and blue pupil; fringe alter- nately black and white; under side clouded, marbled and spotted with bluish, gray, black and white in the middle, at the costa ia a triangular white spot, dusted with black in the centre, near the pos- terior margin is a band of indistinct cordiform or reniform eyelets with a black iris and bluish pupil, between these and the margin is another band of imperfect eyelets in which the iris is gray and the pupil light brown: at the edge of the wing is a macular band of black crescents. This beautiful though common butterfly, to judge from the shape of its wings, seems rather to belong to the genus, or perhaps subgenus, Cynthia; at any rate it forms a connecting link between it and Vanessa.

(Pechius) fusca, alis supra fascia communi articulata angulata ; secundariis subtus macula magna didyma, luteo-pallidis. Peck’s Hesperia, brown, wings above with an angular band common to both; secondaries underneath with a large, didy- mous, irregular spot ; both of pale yellow. PLATE IV, FIG. 2, 3. Expansion of the wings 1 inch and } a line. Taken with the preceding, and also by Professor Peck. DESCRIPTION. Body brown, paler on the under side. Antenne rufous above, below the joints have a patch of white scales; knob fusiform, hooked: wings above tawny-brown, with an articulate angular band, common to both wings, of pale yellow: primaries striped and streaked with the same colour near the base, and in the costal area: underneath the wings are paler; the primaries have nearly the same marks as above but more conspicuous: on the secondaries the angular band is surmounted by another irregular spot, so as to form two contiguous spots, or rather one large irregular didymous one. This species does not appear to belong to either Thymele or Pamphila of Fabricius, as their characters are detailed by Mr. Stephens in his excellent Ld/ustrations of British Entomology. In both of these the palpi are thickly cloathed with hair and the terminal joint is obtuse; but in H. Pechius the palpi may be described as thickly cloathed with elongated divergent scales, with the terminal joint emerging, naked, and acute. 4 Haustellat. i, 97, 99. ZYGENIDEZ—SPHINGIDE. 301 II.

Body ash-coloured: thorax with a large trapezoidal brown spot dilated next the abdomen: pn- maries angulated, ash-coloured, with a transverse series of brown submarginal crescents in a paler band, between which and the posterior margin is another obsolete paler one; above the crescents is a straight whitish band, and a linear angular forked one under the internal sinuses of which the wings are clouded with dark brown; underneath the above markings of the wing are very indistinct : the secondaries are rose-colour, paler at the costal and posterior margins; underneath they are dusky- cinereous, with a whitish band coinciding with that of the primaries, a transverse series -of crescents and a dentated brownish band, all rather indistinct : but the most conspicuous character of the second- aries is a large eyelet situated at the anal angle, consisting of 2 black pupil, nearly but not quite surrounded by a blue iris, and situated in a black triangular spot or atmosphere, which extends to the anal angle, and is surmounted by some blue scales: the abdomen above is dusky ash-coloured. This insect appears to be the American representative of S. ocellatus, from which however it differs considerably. It comes very near to S. geminatus (Say Am. Ent. i, t. xii,) but in that the eyelet has two blue pupils. CXC. Genus DEILEPHILA. Ochs. (423) 1. * DEILEPHILA INTERMEDIA. Intermediate Deilephila. D.

The silvery rectangular spot in the primary wings of this insect, when they are brought near to each other, forms a quadrangular area very much resembling a picture in a silver frame. > NOCTUID. 307 (430) 2.

Body, legs, and antennz, fawn-coloured, as are likewise the paler parts of the wings: primaries clouded and streaked with dark, and reddish-brown; the disk of these wings is occupied by a large cloud of this colour inscribed with two, sometimes silvery, and sometimes golden, briiliant metallic spots, tending to form an obtuse angle with each other: the upper one, or that nearest the base of the wing being acuminated towards that part, rounded towards the apex, and sending forth two branches towards the costal area; the lower spot is subtriangular or V-shaped, with the point towards the base of the wings: the two together form, in some sort, a semicolon reversed : between the lower or ovate spot and the costa, is a rather indistinct circlet of gold or silver, and two streaks of the same lustre may be traced lower down between it and the inner margin of the wing; the disk near the apex is bronzed; from the brown cloud mentioned above runs a wavy brown streak to the exter- nal apical angle, the apex itself is terminated by a band formed by indistinct black crescents; and above the streak is a transverse band formed by two faint lines of dark indistinct crescents including a pale band: secondary wings darker at the apex. N.B. In the Nova Seon specimens the discoidal spots are silvery, while in that from Canada their lustre is golden. The synonymy of this species seems very doubtful: the metallic signature can scarcely be said to represent either a mark of interrogation, or a greek Jota reversed: they most resemble a semicolon.

Linné under this species refers to one noticed by Ray ;’ but Ray describes the wings as “ punctis nigris creberrimis picté,”’ words which evidently refer to B. medius ; Mr. Samouelle, perhaps induced by this reference, has figured the latter insect® as B. major. ‘The reference in Syst. Nat. also to Geoffroy’ appears to be incorrect, for Linné describes the wing of this species not as basi fusca as Geoffroy does; but in these words “ ale dimidium longitudinaliter fuscum.” Geoffroy, as well as Reaumur,! who is also quoted by more authors for this species, probably had the B. minior in their eye, the wings of which Linné describes as “ antice versus basin obsolete fuscescentes.”? 7 Hist.

The references to groups, whose characters are given in the text, are in sMALL CAPITALS. Those to the species described are given so fully, in the table of contents prefixed to the volume, that it is unnecessary to repeat them. Synonymes and groups or species incidentally noticed are in Italics. they imply that the species is described under that name in the wark. Where Roman characters are used to indicate any Trivial name, N.B. In the text of this volume an asterisk (*) prefixed to a genus or species, signifies that it is non-descript : an obelus (+) prefixed to a word, that it is a subgenus.
