CURCULIONIDES.— Part I. By HENRI JEKEL, MEMBER OF THE ENTOMOLOGICAL SOCIETY OF FRANCE, ETC, LONDON: JOHN VAN VOORST, PATERNOSTER ROW. PREFACE. I am indebted to Mons. H. Jekel for the descriptions of Curculionidse in the following pages, which form a continuation of the ‘ Insecta Saundersiana.’ My original plan has been slightly departed from, by allowing the Author to introduce the charac¬ ters of a few species not in my collection, chiefly with a view of bringing nearly allied species together : these are clearly designated in the text by an asterisk prefixed. * W. WILSON SAUNDERS. East Hill , Wandsworth, Jan. 30 th, 1855. INSECTA SAUNDERSIANA. COLEOPTERA. Fam. CUECULIONIDES. PART I. Div. BRUCHID^, Sell. The Bruchidae, in respect to the various peculiar characters which distinguish them from the true Curculionidae and other aberrant groups of Rhynchophora, as well as from their habits and food, require to be ele¬ vated to a parallel rant with that division ; for few other groups in the Coleoptera have such constant and important characteristics. They are ex¬ tremely numerous in species ; and if, in addition to the 300 species (at least) already described, we take into consideration the 150 new species in my cabinet, and a still larger number which I have seen in many collec¬ tions, as well as all those in the numerous museums unknown to me, we may, without exaggeration, conjecture that their number exceeds 1000, without including the large number not yet detected. They indeed form one of the most natural groups in the Order Coleoptera, and they require, from their great number, to be still further subdivided, especially in the genus Bruchus, as restricted by Schonherr. A rather natural group of species, having the body very thick and the pygidium perpendicular ( Br . Pescaprce , Coryphee , &c.), is certainly wrongly placed amidst the ordinary flattened species, having the pygidium oblique, and should, on the other hand, be placed next to the Pachymeri, to which they should link the true INSECTA SAUNDERSIANA. Bruclii. I have already prepared materials for dividing them more natu¬ rally than by the presence or absence of a spine upon the thighs ; and I hope I have found sufficient characters in the structure of the thighs and tibiae, which, as far as I have observed (combined with a peculiar shape of the body, thorax, and antennas), are of real importance, both scientifically and naturally. Nevertheless, as my investigation is not completely terminated, I will not here propose for the above-mentioned forms new generic names, although there would be no difficulty in characterising them : but I in¬ sist, in my descriptions, upon certain characters which will help the reader to recognise to what new generic form the species pertain. I therefore trust the extension of some of the following descriptions will be pardoned. Genus BRUCHUS, j or. diet. Sch. (Grex 1). Stirps I.

Nearly allied to Br. Lebasii, but differing, as far as T can judge from a single specimen, in having the thorax broader, more convex, the poste¬ rior angles less acute, its punctures less deep and rugose,1 wanting the two 1 I must here observe that Schonherr’s description of Br. Lebasii (v 25) does not agree completely with the nature of the punctures of the COLEOPTEKA. 3 basal impressions ; the elytra broader, more rounded ; and the entire body black (except the antennae and legs), and proportionally wider. Head oblong-quadrate, inflected, convex, rather densely punctate ; front between the eyes longitudinally ridged ; black, with a slight gray pile. Eyes transverse, semi-lunar, lateral, leaving the front almost as wide as the vertex and the rostrum at its base ; pitchy. Rostrum short, evi¬ dently narrowed and rounded towards the apex, slightly impressed at the middle of the base ; deeply punctate-rugose ; black, subglabrous ; apical parts of the mouth ferruginous : maxillary palpi elongate, rather thick, pitchy black. Antennae rather short and thick, a little longer than the thorax, enlarged towards the tip ; 1st joint ovate-cylindric, rather long; 2nd and 3rd together shorter than the 1st, equal, subglobose ; 4th to 10th transverse, gradually wider and more triangular within ; terminal longer, shortly ovate ; ferruginous, subglabrous. Thorax subconic, nearly as long as the width at the base ; apex sub- truncate, or scarcely produced in the middle ; sides nearly straight, or very little rounded, obliquely widened towards the posterior angles, which are acute ; base obliquely quadri-sinuate, produced in the middle which is bilo- bate ; convex ; rather densely and deeply punctate-subrugose, more strongly at the sides ; black, with the sides widely but not densely covered with an ashy gray pile. Scutellum rather large, subquadrate, divided longitudinally into two parts, each of them rounded at the apex, forming a moderate emargination; densely clothed with a long thick whitish pile. Elytra shortly ovate, twice the length of the thorax ; base as wide as the latter, sinuate, rather emarginate in the middle for the reception of the produced part of the thorax, subangular at the side, where the shoulders thorax : many specimens from Lebas have not exactly the thorax “ crebre punctatus,” but certainly “ crebre punctato-rugosus, praesertim postice, ” when viewed through a strong magnifier ; other specimens, from Caraccas, having the thorax shaped like that of Br. Batesii , wanting also the basal impression appearing in Lebasii, I consider as a third species, differently coloured, and distinct from both. I have in my collection about a dozen new species, from different parts of Columbia, collected by several natural¬ ists at different times, all of them of the same division, and closely allied to each other, but, when carefully observed, very distinct, as is also the case with our European species. 4 INSEOTA SAUNDERSIANA. are callose ; sides rather widened towards the middle, then nearly to the apex nearly straight, scarcely narrowed ; afterwards roundly angustate towards the apex, which is semicircular in each elytron ; sutural angle rounded ; rather convex ; punctate-striate, punctures more distant and deeper at the base, gradually closer and smaller towards the apex ; inter¬ stices transversely rugulose, more regular and approximate towards the apex ; black ; having a large fascia interrupted near the suture, rising from under the base behind the shoulders, ending at the middle of the elytra, where it is somewhat rounded, also obsoletely extended near the base in its middle, and formed of yellowish gray pile. Pygidium subovate, obtusely pointed at the apex, oblique, convex, more than half the length of the elytra, longer than the thorax ; punctate- rugose, covered with a rather dense yellowish gray pile. Body beneath punctulate, covered with a light silvery gray pile. Legs punctulate : anterior small, slender, flavescent-ferruginous : thighs clavate, with a small tooth inside before the apex : tihice enlarged towards the tip, w'hich is truncate and terminated by the four ordinary short spines ; they are shorter than the thighs : tarsi longer than the tibiae, with the first joint of nearly half the entire length of the tarsus ; all the tarsi have their terminal joint with the claw blackish. Obs. — This species is named in honour of the dauntless traveller, whose researches in Natural History have enriched science with many in¬ teresting novelties. Manipulus ii.

Pescaprce, Sch., of which I was formerly inclined to consider it a variety ; but from being only half the size, its elytra less impressed along the suture, more rounded at the apex, and having a white oblique band, I think it sufficiently distinct. Its size is exactly that of Br. Bixce, Sch., which it resembles also in shape. Body shortly oval, very thick, truncate at the apex, with the pygidium perpendicular. Head between the eyes conic, acutely elevated in the middle ; black, punctulate. Eyes large, obliquely approaching towards the rostrum. Ros¬ trum (with the mandibles somewhat exserted) a little longer than the head, pitchy black, finely punctulate, subglabrous. Mouth beneath rufous, with the maxillary palpi pitchy. Antennae half the length of the body, reaching beyond the base of the thorax ; 1st to 3rd joints rufous ; the 1st long, thick, curved ; 2nd short, thin, obconic ; 3rd twice as long as the 2nd, not more than half the length of the 1st, subconic ; the remainder pitchy brown, to- mentose, gradually more serrated inside to the 9th; the 10th and 11th a little less transverse. Thorax subconic, shorter than the width of the base, three times nar¬ rower at the apex ; sides nearly straight, or slightly rounded ; posterior angles acute ; base oblique, sinuate, produced in the middle, which is lo- bated ; above rather convex, with two longitudinal convex elevations, sepa¬ rated from each other by a deep and narrow channel from the base to the apex ; at each side of these elevations is a canaliform longitudinal impres¬ sion, deeper at the base, evanescent towards the apex ; covered with a brown-grayish pile, except on the elevations, which are subglabrous and distinctly transversely rugose ; the rugosities of the remaining parts are less distinct, and hidden by the pile. Scutellum subtriangular, pitchy, covered with a light brown pile. Elytra when united subquadrate, somewhat longer than wide, a little narrower at the apex, which is obtusely rounded ; base emarginate in the middle for the reception of the produced part of the thorax, then slightly obliquely produced towards the sides, where they are as wide as the thorax ; somewhat obliquely dilated at the shoulders, which are rounded, rather callose ; thence the sides slightly decrease in width towards the apex ; slightly depressed along the suture ; punctate-substriate, the punc¬ tures remote ; interstices plane, except the 2nd, which is convex, especially near the base, and an elongate callosity, being the continuation of the shoulder, crossing rather obliquely the 6th and 7th interstices, evanescent 6 INSECT A SAUNDEESIANA. towards the third part of the length ; both this callosity and the basal part of the 2nd interstice denudate, transversely rugose ; remainder of the elytra indistinctly rugulose ; covered with a grayish brown pile, having a white band rising from the shoulder, where it is narrow, obliquely directed to¬ wards the suture, where it meets with the corresponding band at the mid¬ dle of the length of the elytra, being there widened and more distinct, forming a large central irregular spot ; with here and there, especially near the apex, some whitish maculae, very small, punctiform, scarcely distinct. Pygidium oblong-subconic, perpendicular, finely and densely punc¬ tate, covered with a dense yellowish white pile. Body beneath : — Pectus finely punctate, with a slight dark brown pile ; posterior margin having a large white band. Pectoral lamince black, shining, glabrous, having deep distant punctures ; posterior margin raised in a thin pad. Abdomen pitchy, finely and densely punctate, covered with a thin, short, brown-grayish pile. Legs having their thighs pitchy, with the knees, tibise and tarsi ru¬ fous; the posterior darker. Four anterior rather thin and short: thighs scarcely clavate, edentate : tibice subcylindvic, slightly curvate, truncate at the apex. Posterior long, rather thick: thighs long, extended beyond the apex of the abdomen, subclavate, edentate : tibice nearly as long as the thighs, thin at the base, where they are somewhat bent, then evidently wi¬ dened towards the apex ; nearly flat beneath, convex and subtelragonal on the upper side, with four longitudinal ridges, two lateral, one sublateral outside, one subcentral, each of them terminated at the apex by a spine, the internal long, the others very short. Obs. — Though no indication is given of the habitat of this species, analogy leads me to believe it to be a South American, and probably a Brazilian insect. I have only seen two specimens.

This beautiful species is about the size of Br. Pisi , L., but somewhat shorter, though of the same width, and consequently proportionally broader. Head oblong-subquadrate, convex between the eyes, transversely im¬ pressed behind them, where it forms a sort of neck, somewhat shorter than the fore part (or front) ; deeply punctate, a little more densely on the neck (or vertex) ; there is in the middle of the base of the forehead, near the transversal impression, a small subtriangular polished impunctate patch, somewhat elevated, obsoletely continued amidst the punctures towards the rostrum. Eyes large, sublimate, convex, obliquely approaching towards the apex of the crown, which is thus conically narrowed towards the ros¬ trum. Rostrum about the length of the head (neck included), narrower than its posterior part; apex subtruncate ; black, shining, coarsely punc- tato -rugose, except the apical margin, which is very finely and densely punctulate ; base slightly impressed in the middle ; sides above the eyes having some whitish pile. Labrum transverse, rounded at the apex; black, shining, polished, with a transverse line of small punctures. Mandibles rather thick and convex, extended sideways, where they are rounded ; pointed at the apex ; coarsely punctato-rugose. Palpi black, subcylindric ; terminal joint the longest, that of the maxillary pair very long. Mouth underneath fulvous at the apex. Antennce thick, reaching the base of the thorax (length § lin. — 1T^ millim.); black, dark leaden-tomentose, with the three or four basal joints reddish beneath, the 1st lighter and shining ; 1st joint ovate-subconic; 2nd subcylindric, longer than wide; the rest slender ; 3rd and 4th nearly equal, somewhat longer and wider than the 2nd, cylindric-subconic ; 5th to 9th of equal length, but all wide, trans¬ verse, angularly dilated inside, 8th and 9th the widest ; 10th shorter and narrower than the two preceding joints, less angular within ; terminal joint shortly ovate, narrower, obliquely truncate on the outside, with the apex acute. Thorax subconic, semicircularly produced at the apex, which is three times narrower than the base ; sides oblique, nearly straight, scarcely rounded in the middle ; about as long as the width of the base; posterior augles acute ; base subtransversely and straightly cut from the angles to somewhat more than half the distance to the middle, where it is abruptly obliquely produced, then widely cut in a straight line with a very slight INSECTA SAUNDERSIANA. appearance of emargination in the middle above the scutellum ; convex, especially in the middle near the apex ; with coarse and deep punctures somewhat distant, and between them minute punctures and rugosities here and there denudate and shining ; densely covered with a white pile of a fine texture, with the middle black, having a thick short black velvet pile, here and there wanting, leaving the aforesaid shining patches ; this black spot is nearly in the form of a lozenge truncate at its apical angle ; it em¬ braces almost the whole of the upper part of the apex, its sides are nearly as oblique as the sides of the thorax, running very near them as far as the middle of the length, where they form an angle, then run obliquely inwards, and meet together subangularly above the middle of the base. Scutellum transverse, nearly of a reversed cordate form, densely clothed with a white pile. Elytra broad, together nearly as wide as long, more than twice the length of the thorax, and being at least of the same width at the base, which is closely applied to it, being emarginate in the middle for the re¬ ception of its produced part and the scutellum, thence straightly truncate from the middle of each to the side ; shoulders callose ; sides somewhat widened to two-thirds of the length, thence rather abruptly rounded to¬ wards the apex, which is semicircular in each elytron, with the sutural angle obtusely rounded ; very slightly convex ; narrowly punctate-striate ; punctures deep at the base, then slightly impressed ; interstices wide, ra¬ ther coarsely rugose, especially at the base, here and there denudate, shin¬ ing ; black ; suture in the middle widely covered with a white pile of a fine texture, forming together a large subcentral subhexagonal spot, which sends from its angles six narrow branches, of which two are sutural ; one posterior, sublinear, reaching the apex, the other (or anterior) wider, bifur¬ cate behind the scutellum (which it incloses) to the base ; the. four remaining branches (two on each elytron) subtransverse ; one above the middle, quite transverse, slender, not reaching the margin ; the second much behind the middle, subobliquely directed downwards to the margin, which it reaches; this central spot with its branches nearly resembles a six-branched cross, of which the two sutural ones being divided by the suture give four upon each elytron, the spot being also divided by the suture, there is a half cross upon each ; the branches have between them three large marginal black spots ; the first basal, large, obliquely widened towards and near the suture beneath the scutellum ; the second much smaller, joining the first at the margin, reaching only the middle of the COLEOPTERA. 9 elytron between the fourth and fifth striae, where it is narrowly rounded ; the third apical, as large as the basal one, but extending nearer to the su¬ ture, at the first stria, where it is obtusely rounded ; these three black spots are covered with a dull, black, short and thick velvet pile, here and there wanting, especially on the basal one at the shoulder. Pygulium ob3ique, somewhat longer than wide, convex posteriorly ; densely covered with a white pile ; having a small longitudinally ovate black spot at each side of the margin, a little beneath the base and the apex of elytra. Body beneath punctulate, densely covered with a white pile. Pectoral lamina glabrous, shining, deeply punctulate, the margin only being clothed with white hairs. Legs finely punctulate, black, slightly covered with a long, thin, ob¬ liquely arranged pile, of a silvery gray hue, showing here and there the ground. Anterior thighs and tibia rather thin and short, subcylindric, nearly of the same length, with their tarsi somewhat shorter. Intermediate legs having the same proportions, but their parts are a little more elongated. Posterior legs nearly the length of the body (If lin.), thick: thighs reaching the base of the terminal abdominal segment, clavate, widely subtruncate at the apex, deeply canaliculate inside for receiving part of the tibiae, edentate : tibia evidently shorter, angularly dilated towards the apex, where they are subtruncate; somewhat flat beneath, rounded on the upper side, which is obtusely ridged near the apex ; interior margin and middle of the upper side acutely angular, sharply ridged, each terminated at the apex by a long spine; external angle having also a very short and thin spine : tarsi longer than the tibiae, about the length of the thighs: 1st joint more than half the total length, curved : claws denticulate at the base. Obs. — I have only seen one specimen of this handsome species. I suppose it to be a South American. I am happy in naming it after the learned entomologist whose liberality has endowed the science with several important works, and as a proof of my sincere attachment. o 10 INSECTA SAUNDERSIANA.

Thorax subconic, shorter than the width of its base ; apex subtruncate, nearly half the width of the base ; sides rather abruptly roundly dilated before the middle, then straight, slightly widened towards the base, which is obliquely sinuate, produced in the middle, widely but slightly emarginate above the scutellum ; rather convex; coarsely punctate, punctures rugi- form ; black, clothed with an ashy-gray pile ; middle of the base above the scutellum having a short duplicated line of whitish pubescence. Scutellum subtransverse, semicircular, black. Elytra obtusely ovate, nearly twice and a half the length of the tho¬ rax, and somewhat broader at the base than it ; base obliquely truncate within for the reception of the produced part of the thorax and the scutel¬ lum, then straight, somewhat obliquely produced towards the sides ; shoulders OOLEOPTERA. 11 subcallose, exactly situated behind the angles of the thorax, between the 6th and 8th striae; sides a little obliquely extended behind the shoulders, then straight to beyond the middle, afterwards roundly narrowed towards the apex ; this is also rounded, but less so towards the sutural angle, which is obtuse; slightly convex; narrowly and rather deeply striate-punctate; punctures slightly impressed, approximate; interstices rugulose; black, covered with an ashy gray pile, here and there yellowish. Pygidium subconic, perpendicular, convex, punctate-rugulose ; black, with a slight ashy gray pile. Body beneath : — Pectus densely punctate-rugulose, black, shining, covered with a grayish pile, yellowish on the lateral and posterior margins.

All the claws much incurved, uni- dentate near the base. Obs. — I have seen one specimen only of this small species, which, from the thorax being somewhat rounded at the sides, might be placed in Schonherr’s Stirps II.; but if we consider that he introduced in his Stirps I. such species as lucifugus , &e., having the thorax much shorter and more rounded, “ nullo modo conico,’’ recalling completely the form of the European species of Stirps II., Manip. I. Cent. II., et Manip. II., we re¬ gard this species as belonging to the first Stirps, where it finds its true allies, in general shape, in Br. Galegae , varius , imbricornis, &t\, &c.

This species very much resembles the Br. obtectus, Say, ( pallidipes , Sch.), but it differs in being larger and proportionally more elongate ; the eyes are much larger, more approximate, making the front narrower; the thorax less elongate and convex, more conic ; the scutellum smaller, less quadrate and impressed ; the elytra more elongate, less abruptly dilated behind the shoulders, more narrowed posteriorly, with the apex more rounded, the striae subequally distant ; the pygidium more elongate, longer than the thorax, oblique-subhorizontal, scarcely bent at the apex, &c., &c., independently of a different colour of the ground and pile. * Schonherr placed in this Stirps species having the thorax nearly conic ( Br . humeralis, pallidipes , &c.) and not at all subtrapeziform : hence I regard these three species (< dominicanus , obtectus and palealus) as belong¬ ing properly to the first Stirps. COLEOPTEKA. 13 Head short behind the eyes, substrangular, forming a sort of neck ; there is a longitudinal ridge between the eyes, joined behind to a trans¬ verse subangular one placed behind these organs ; punctate, covered with a fulvous or flavous pile ; black, pitchy or dark rufous. Eyes large, black, coarsely reticulated, more than semicircular, transverse, deeply and angu¬ larly einarginate anteriorly, obliquely approximating towards the rostrum. Rostrum rather small, half as long as the head and narrower than its hinder part, subquadrate, or a little narrowed towards the apex, which is truncate; punctate and clothed like the head, impressed at the middle of the base; rufous. Mandibles rising from the sides of the rostrum close to the eyes, widening it so as to make it as broad as the head behind ; some¬ what exserted at the apex ; dark rufous. Labrum transverse, linear, rufous, glossy. Antennae testaceous, reaching beyond the base of the thorax ; joints 5 — 10 subtriangular, gradually wider and acutely subserrate on the inside of their apex, the 9th and 10th however not broader than long, 11th subovate, acute. Thorax much shorter than broad, subconic ; apex truncate, wider than the neck, nearly half the width of the base ; sides somewhat rounded, but increasing in width to the posterior angles, which are acute ; base trans¬ versely truncate from the angles to the third of the breadth, then obliquely produced behind, then widely truncate to the middle ; the wide median lobe having three impressions as in Br. obtectus (and many others), but shallower; moderately convex, scattered with rather deep and distant punc¬ tures ; each side above the base transversely impressed, also a small fovea (which does not exist on Br. obtectus) on each side of the middle of the disc is perceivable ; coloured and clothed like the head. Scutellum small, subquadrate, with the posterior angles rounded, the apex scarcely emarginate, the middle longitudinally but obsoletely im¬ pressed. Elytra subovate, together sinuately emarginate at the base ; shoulders callose, a little within the sides and the thoracic angles ; sides roundly but moderately dilated from the base to the fourth part of their length, where is their greatest breadth, then straight to two-thirds of their length, afterwards roundly obliquely narrowed towards the apex, which is semicircularly rounded ; sutural single obsolete ; slightly convex, subdeplanate longitudi¬ nally, thinly striate-subpunctate ; 1st stria close to the suture, 6th to 9th shortened anteriorly behind the shoulder, 10th (or marginal) following ex¬ actly the inflected margin, which is widely roundly dilated behind the 14 INSECTA SAUNDERSIANA. base; interstices flat, finely punctulate, showing, when the insect is fresh, rows of distant very small denudate dots ; coloured and clothed like the head and thorax. Pygidium oblong-semielliptic, longer than the thorax, oblique-sub¬ horizontal, punctate, pitchy, covered with a short dense yellowish pile. Body beneath more or less rufescent, here and there spotted with blackish. Pectus rather distantly, abdomen finely and densely, punctate; covered with a thin silky whitish gray or whitish yellow pile ; sides of the rings having a white punctiform spot. Legs: — Four anterior slender, first pair the shortest; pale rufous or testaceous: intermediate thighs flat and concave underneath. Posterior legs nearly as long as the whole body: thighs thick, clavate, having inside near the apex a rather long acute spine or tooth, to which are added two very minute crenulations. Tibice bent at the base, then straight, rather dilated towards the tip, which is subtruncate and has four spines, one inside, one in the middle, and two outside close to each other ; these two latter very minute. Obs. — This species varies in the coloration of the ground and pile : there are specimens of a very light rufous colour ; others much darker, marked with pitchy patches. Some of them are clothed with a yellowish fulvous pile, others with grayish or ashy, and there are specimens which perfectly link these extreme varieties.

This widely distributed species, of which I have seen a number of specimens, varies very little in coloration and size ; the North-American specimens are, however, somewhat smaller There might be added to Fahraeus’s description many unnoticed characters, of which I think it suf¬ ficient to point out the following : — Head having between the eyes a longitudinal ridge, and another trans¬ verse behind them, to which the former is joined, as in Br. dominicanus, above described, but the latter is not angularly connected to the former, as in that species. Thorax having its basal lobe widely truncate and emarginate in the middle, with three longitudinal impressions, one in the middle elongate* thin, canaliform, the two others on each side of this lobe shorter and wider. The sides of the base are subtruncate, with an obsolete impression above them not far from the angles. Lateral sides shortly emarginate above the angles. Scutellum emarginate at the apex, longitudinally impressed. Elytra with the strife approximating in pairs, covered with a grayish or ashy fulvous pile, which, sublinearly condensed and interrupted, leaves between these interruptions fuscous spots, forming a sort of tessellation* often obsolete. Pygidium generally black or pitchy, sometimes rufous ; covered with a pile lighter than on the other upper parts, condensed in a longitudinal whitish line along the middle. Posterior thighs armed beneath near the apex with an acute tooth, to which are added behind two crenulations or minute teeth. Ohs. — This species is not better placed here by Schonherr than his humeralis (which he had formerly placed in the Stirps I.), its thorax being nearly conic, its general shape also pertaining to the Stirps I.

This species extremely resembles Z?r. obtectus, Say, and dominicanus , Deyr., above described ; but it is still smaller than the former and more elongate in all its parts, but shorter in the elytra and longer in the thorax than the latter; it is also scarcely half its size.1 In the Latin diagnosis of each of three species, I have endeavoured to point out their differential characters; and I think it more serviceable to add the following compara¬ tive particulars concerning this species than to give a minute description which would not attain the proposed aim of distinguishing the three spe¬ cies from each other: — Head , eyes, front and rostrum as in Br. obtectus , but the frontal ridge is less indicated, and the posterior transverse one is reduced to an obsolete impression. Antennae entirely rufous, as in Br. dominicanus. Thorax longer and narrower than in obtectus , evidently longer than broad, less convex longitudinally (scarcely more than in dominicanus ), the sides less rounded ; the posterior impression near the angle is evidently circular. Scutellum much larger than in dominicanus, but somewhat smaller (proportionally) than in obtectus, which it resembles in form, being however proportionally shorter, less emarginate at the apex, and also less impressed longitudinally. Its size is that of Br. granarius , but it is much narrower. COLEOPTERA. 17 Elytra scarcely more elongate than in obtectus , but narrowed beyond the middle and circularly rounded at the apex as in dominicanus ; the su¬ tural angle is very obtusely, but evidently, rounded ; the striae are sub¬ approximate, in pairs, as in the former. They are covered with a yellowish fulvous pile, not tessellated. Pygidium as in obtectus , less strongly rugulose, more oblique, but not subhorizontal as in dominicanus , which has it much longer and not bent at the apex. Pectus a little darker than the remaining parts of the insect, which are rufous as in dominicanus , of which the pectus is also rufous. Legs entirely rufous, as in the latter, with no appearance of the dark colouring of the posterior thighs observable in obtectus. Obs. — Br. centralism Sch. (t. v. p. 1, pag. 92), nearly approaches this species, but from the description it is a distinct species : I know about a dozen species analogous to these, one of which I regard as a variety of centralis.

Nearly allied to Br. umbrinus ( Pachym .), Kl., Sch., but differs in having the scutellum subquadrate, the elytra not callose near the apex, and the posterior thighs not crenulate beneath before the apical spines. About the width of Br. Pisi, but much shorter. Head oblong -subquadrate, transversely impressed behind the eyes, where it forms a sort of neck nearly as long as the forehead, which has in the middle a high ridge extending from the transverse impression to the base of the rostrum, where it is obsolete ; upper part of the vertex convex, densely punctate, covered with a dense longitudinally arranged ferruginous- brown pile ; part between the eyes (front) coarsely and distantly punctate, with a slighter pile of the same colour, placed transversely. Eyes large, crescent-shaped, obliquely approaching towards the rostrum in front, coarsely reticulate, pitchy.

This species, widely distributed in the South-American continent, varies much in size and colour. Gyllenhal and Sehonherr having had specimens without antennas, and having omitted several particularities, I think it useful to add the following characters : — Antennae moderate sized, reaching the base of the thorax: basal and apical joints more or less light ferruginous; generally black or dark fuscous from the 5th to the 10th, but sometimes the 7th to 10th only are black ; in some of those individuals where the dark colour is more extended, the ter¬ minal joint is also fuscous, but always lighter. Thorax longitudinally elevated in the middle; this elevation divided by a thin longitudinal channel ; each side of the base having a tubercle separated from the central elevation by a deep impression. Elytra having at their base, exactly behind the thoracieal tubercle, a short callosity, and their shoulders are also callose : these form a transverse basal row of four tubercles (two on each elytron) ; they have also a minute callosity a little above the apex. Pygidium ovate-subtrigonal, subperpendicular, rather convex, with a small tubercle in the middle of each lateral margin. 22 INSEC TA SAUNDERSIANA. Pachymerus plagicqrnis, JeJcel.

Obs. — This genus, of which I only know one species, participates, in its characters, with Pachymerus and Caryoborus. Its general elongate form and the structure of the posterior thighs and tibiae place it near the latter, but its moderate sized and finely (proportionally) reticulated eyes and its short antennae, having the 5 — 10 joints much wider than long, se¬ parate it from them ; it also differs in having the elytra flattened and the thorax nearly rhombical, or obliquely and subangularly produced from the posterior angles to the middle of the base, and obliquely narrowed towards the apex; the elytra are also consequently deeply emarginate. All these characters, of the eyes, antennae, thorax and elytra, approach towards Pa - chymerus, but the elongation of the elytra, the tibiae long, linear, incurvate, having at the inner side of the apex no true spine, and also the form of the thighs as in Caryoborus , distinguish it from them, as well as from the Bruchi , properly so called. The scutellum is also proportionally much smaller than in any other group of the Bruchidce.

This division, though much more nearly connected than the preceding with the true Curculionidae, in the general shape of the body and the cha¬ racters of the rostrum and parts of the mouth, possesses, nevertheless, a number of characters so different and essential, that they ought to be raised to an equal rank with that division, and to form a special family. The old authors had indeed distinguished them, like the latter, from the typical group of this Schonherrian family. Although perhaps less numerous in species than the Bruchidae, they are rather extensive, and, like them, pro¬ portionally to their number, very few have been described. About 200 38 INSECTA SAUNDERSIANA. have been described, distributed by Sehonherr in nearly 30 genera: they, like the Cerambycidae and Prionidae, vary so much in generic forms, each containing but few species, that, subdivisions being once introduced, it is difficult to determine where to stay; therefore I have been compelled to establish a proportionally great number of genera for insects which could not enter into the groups already formed, as in the actual state of the science I could neither unnaturally join them to those groups nor describe them doubtingly as species of Anthribus. If we consider that more than 300 new species exist in the different collections with which I am ac¬ quainted, without reckoning the 200 undescribed in my own cabinet, there are probably not fewer than 1000 species in the whole of the entomological collections, whence the number of genera established will scarcely seem to be exaggerated. Though not satisfied with the artificial system of Sehonherr, founded principally upon the form of the antennal groove and eyes, I provisionally group the genera and species according to this classification, intending to discuss the natural position of the new genera under their respective descriptions. Genus PTYCHODERES, Sch. Sehonherr placed in the 2nd Stirps of his genus Phlceotragus three American species having no other resemblance to his type Phi. Heros , F., and his other African species, than the form of the antennal groove, since in all their remaining characters they differ much more from them than from the Ptychoderi , from which, in a natural (as well as a geographical) distribution, they should not be so far removed. On the contrary, I find that none of the genera of Anthribidse with which I am acquainted have so many affinities with the Ptychoderi as these American species. Never¬ theless, my opinion is that the Phlceotragi themselves would be better placed near this genus, if we give to the shape of the antennal groove a secondary value. Indeed, if we consider this character, we find that in the Ptychoderi themselves, as well as in other genera of this family, it varies from the most strongly indicated and deep prolongation beneath to the shallowest and most obsolete impression. The more I have studied this character the more I find it impossible to regard it as of primary value in a natural arrangement of the group. I have indeed prepared a new distribution, which, not being yet entirely terminated, I propose to publish in the ‘ Fabricia Entomologica,’ and which, moreover, would not find its place COLEOPTERA. 39 here. The following observations are, however, necessary in the present work : — Phlceotragus, Sch. AFRICAN SPECIES. Caput breve, latum, transversum, subconicum, pone oculos parum exsertum, basi latum, fronte la- tiore. Rostrum proportionaliter latius et brevius, medio longitudinaliter anguste impressum et carinatum, inter antennas supra haud aut nul- lo modo, infra lateraliter magis, ampliatum. Antennce utroque sexu crassae. Elytra convexa, medio disci lon¬ gitudinaliter non depressa. Pedes crassiusculi : dente ungui- culi singuli intra basin inserto, subparallelo, sublibero. AMERICAN SPECIES. Caput latitudine longius, pone oculos valde exsertum ibique sub- quadratum, angustnm el subtubu- latum, fronte angustiore.

Antennce utroque sexu tenues. Elytra minus convexa, dorso longitudinaliter impresso - depla- nata. Pedes tenuiusculi: dente ungui- culi singuli infra basin inserto, basi connexo, evidenter divergente. Thus, by removing these American species and approximating them towards the Ptychoderi , and joining to the latter other similar insects of the same Continent, we find the following differences, which divide them into three genera: — I. Rostrum lateribus ab oculo ad scrobem antennarum carinatum et canaliculatum ; scrobe plus minusve elongata, infra oblique ducta, interdum interrupta. A. Rostrum longiusculum, basi latiusculum, latitudine basali non duplo longius, lateribus versus apicem paullo ampliatum ; medio disci tricarinato, carinis approximate, quorum late- ralibus media subparallelis, aut versus oculos paullo diver- gentibus ; basi lateribus inter oculum et scrobem antennarum tricarinata, carinis obliquis, duabus superioribus ad marginem 40 INSECTA SAUNDERSIANA. superam scrobis directis et approximatis, ibique saspe con- junctis, quarurn infera continuationem superam scrobis marginat, tertiaque magis distante, infera, prolongationi scrobis parallela ; demum carinis basi rostri supra lateribusque simul novem ; scrobe obliqua, elongata, basi subcirculari, cavernosa, dein sublineari, infra usque prope basin rostri ducta, raro subinterrupta. Pedes breviusculi : femoribus posticis apicem segmenti tertii abdominis non attingentibus. — Ptychoderes , Sch. B.

Pedes longiusculi : femoribus posticis medium segmenti quarti abdominis superantibus. — Hypselotropis , Jekel. II. Rostrum lateribus ab oculo ad scrobem antennarum subteres, nullo modo carinatum, interdum subimpressum, aut rugulosum aut sub- lseve ; scrobe subcirculari, brevi, infra raro per impressionem inter- ruptam laevem oblique continuata. — Tribotropis , Jekel. Thus the genus Phlceotragus remains quite homogeneous, and the formerly misplaced American species are arranged near the Ptychoderi of Schonherr, and become types of two new genera. As may have been ob¬ served in the preceding characters, there is in these species a more or less distinct continuation of the groove beneath, and by them we are naturally led to the Phlceotragi and other elongate genera, in which the groove is only circular or ovate, without any appearance of continuation beneath. COLEOPTEEA. 41 1. Genus PTYCHODERES, Sch. As above stated, this genus is here regarded as restricted by Schonherr, and forms one of the most homogeneous genera in the family. The resem¬ blance of the species is so great that they not only have the same sculpture, but their coloration is also disposed in the same manner. To the charac¬ ters given by Schonherr I have to add the following : — Dorsal ridges of the rostrum always more elevated and distinct in the male than in the female : the median continued in front between the eyes, where, close to and on each side of it, there is another very short and thinner, and also less distinct in the female : this often joins the lateral one of the disc of the rostrum at its anterior extremity, at the place where it runs obliquely towards the eye. Rostrum a little dilated at the apex, longer in the most developed males, but always shorter in the females than in the less developed males. Antennae of the males gradually more elon¬ gated, according to the development in size of the specimens : generally, in the largest, they are nearly as long as the body, sometimes longer, and they gradually decrease in length with the proportional diminution of size of the specimens. Taking Pt. elongatus as the type of this curious varia¬ tion, of the numerous specimens I have seen, hardly one example smaller than another has occurred with a more elongate antenna. Males, two or three times smaller than the largest specimens, have the antennse reaching at least the base of the elytra ; whilst those of the females (which compara¬ tively vary very slightly in size, and reach at least the intermediate size of the males) hardly reach the posterior carina of the thorax. The clava, though it seems in the males to become gradually narrower proportionally as the body increases in size and the antennae become more elongate, in¬ creases only in a decided manner in its first joint, which corresponds with the gradual elongation of the joints of the funiculus, the two terminal joints proportionally increasing very slightly. In the females the clava is broader than in the smallest males (proportionally), and consequently less elongate, having, especially, its terminal joint much shorter, more conic and subpyriform. The thorax affects a similar outline in all the species with a depression on the upper side ; its posterior carina also varies very little : its coloration beneath is like that of the abdomen and pectus, more or less whitish tomentose, with a sublateral narrow blackish band, always G 42 INSECTA SAUNDEKSIANA. darker than any other part of the body, and composed of a fine thick velvet¬ like tomentosity. The upper part of the sides is clothed with more or less fuscescent tomentosity, coloured like that of the sides of the elytra. Finally, the depressed part of the disc is clothed, like the depressed part of the elytra, with a more or less whitish, yellowish, fulvescent, ferruginous or greenish tomentosity, adorned with fuscescent spots or lined®, the most important of which are two apical and two basal ones. The elytra are, in all the species, more or less regularly or densely punctate-substriate, with their interstices flat ( Pt . depressus only having the appearance of alternate interstices subelevated behind), more or less transversely rugulose ante¬ riorly. I have found it impossible to use these characters for the distinc¬ tion of the species, since not only they have nearly the same degree of weight in all the species, but also, with a few exceptions, they vary as much between specimens of the same species as between the species them¬ selves : their common lighter band varies, as has been said of the thorax , not only according to the species, but often in the different specimens, from being more or less rubbed or fresh. This band is generally distinctly cir¬ cumscribed at its sides, deeply emarginate at the middle and above the apex: these emarginations have been produced by the darker ground¬ colour of the sides extending inwards, and they are always darker than the sides themselves, for these are always more or less mixed with the same colour as the band, whilst the emarginations are nearly unicolor, forming large more or less triangular maculae (the median), or more or less rounded and irregular spots (ante-apical) : each of them is rarely transformed (as in Pt. virgatus ) into two connected oblong lineolae ; in this case the band is hardly distinguished from the lateral colour (Pt. virgatus and mixtus) : finally, in one species, the colour is subequally distributed over the whole of the elytra, the sides being scarcely darker than the disc, and this has the ordinary dark maculae circumscribed all round by the general colour (Pt. viridanus ). From these variations I might point out several differences for the distinction of the species, but the most important characters I have found are the proportions of length and posterior attenuation of the elytra, their depression on the disc, their lateral convexity and inflection, their longitudinal outline or profile, their posterior declivity, and, finally, the presence or absence of the ante-apical callosities or tubercles, their form, &c. The body beneath increases or decreases in thickness according to the upper convexity or flatness of the thorax and elytra: its coloration uniformly agrees with that of the thorax beneath. The pectus and abdo- COLEOPTERA. 43 men are more or less punctate, but I cannot use this character, as it is as variable as the sculpture of the elytra. The abdomen is very often denuded in the middle, and it offers at the base of the sides of the segments more or less apparent maculae, which are constant in very few species. The legs are rather short and not slender ; the intermediate thighs do not extend beyond the base of the posterior, and the latter never extend beyond the apex of the third segment of the abdomen, only reaching in the majority to its middle. The tibiae are very slightly or but scarcely longer than the thighs, especially the posterior; they are a little dilated at the apex: the tarsi are nearly of the same length; their first joint is only one-third of the total length, and is never more than thrice, and very often not more than twice, as long as its apical breadth, especially in the anterior legs, which are densely clothed with the same pubescence as the body beneath, and annulated with black or fuscous. All these characters, independently of those given above, are sufficient to distinguish this genus from the allied elongated American forms. After much difficulty, I have adopted the following distribution of the species : — I.

As may be seen, from the characters here above detailed, the first two divisions contain the most depressed species, and the three others the most convex, scarcely depressed in the elytra (except Pt. antiquus , in which the depression approaches that of Pt. elongatus and its allies, but with the ante-apical callosity nearly obsolete) ; and the last species, Pt. virgatus , one of the least depressed, without callosities, leads again to the Pt. depres- sus in the structure of the antennae in the male.

This species is the most widely and deeply depressed in the elytra of of any of the insects in this genus. It is, in proportion to its length, the broadest of the depressed species. The rostrum is the most robust amongst them, and the shortest, in proportion to its development in the male as well as in the female. The thorax is the broadest and shortest, proportionally more so than in Pt. nebulosus , and it is impressed like the latter and Pt. elon- gatus. The elytra are broader in proportion to their length than in all the depressed species, except perhaps in large males of Pt. nebulosus , and hardly more elongate than in Pt. viridanus : they are much more deeply depressed on the disc than in the largest males of Pt. elongatus , in which the depression is at its greatest extent, more roundly and obliquely flattened to the ante-apical callosity, which is slightly conical, short, and does not attain to the perpendicular level of the apex, which is subobliquely cut off behind it: their sides, from the widening of the depression, are subperpen- dicularly inflected and subcompressed to the margin, which is more roundly dilated beneath the base than in Pt. elongatus. The marginal stria is also more clearly indicated, — as much so, at least, as in Pt. tricostifrons (which has the margin as roundly dilated beneath the base, but the sides are ob¬ liquely inflected). The borders of the discoidal depression are more ele¬ vated than in any other species, subcarinate, and placed between the fourth and fifth striae. The alternate interstices, the innermost posteriorly, the median (which forms the cariniform limit of the depression) and the exter¬ nal one almost entirely are a little elevated, narrowly convex, and poste¬ riorly marked with short fuscous hairs, more evident in the male, — a character which I have found in this species only. The general colour is that of Pt. elongatus , but the whitish common band of the elytra is much wider, agreeing with the breadth of the de¬ pression ; its sides are much less sinuate, or rather they are very slightly emarginate in the middle and above the apex ; the median emargination is very shallow, extending only between the fourth and third striae, having a depth of hardly more than one interstice, and the posterior is obsoletely indicated, so that the ordinary large maculae formed by them are reduced to intra-lateral lineolae. 46 INSECTA SAUNDERSLANA. Obs. — The tetragonal form of the joints of the antennae in the male is the only point of connection between this species and Pt. viridanus , Sch.; its general shape and coloration, and especially the extreme depression of the disc, place it much better with Pt. elongatus and its allies.

This species, the most common in our collections, seems to be widely distributed in the South-American continent, extending from the most COLEOPTERA. 47 southern parts of Brazil to Para (and Cayenne?) It is the largest species, reaching to 12£ lines in length, including the head and rostrum, but one of the narrowest in proportion to its length, and the most elongate in its various organs. When looked at from the side it is the flattest in the body and elytra, and (except Pt. depressus, Jekel) it maybe regarded as the most widely and strongly depressed on the disc. Head elongate behind the eyes, evidently longer than wide, scarcely convex lengthwise, the most depressed of the genus. Rostrum very long in both sexes, being in the male a third and in the female a fourth longer than the basal breadth, slightly narrower than the head. Antennce varying in length, according to the size of the specimens of the male, with the in¬ termediate development between the two extremes above described ; those of the female, as far as I have observed, scarcely vary. Thorax (like that of Pt. obsoletus , Jekel) the most elongate of the genus, in the male one-sixth and in the female one-eighth longer than broad, as widely and deeply depressed on the disc as in Pt. depressus , and less thickly rounded at the sides and beneath than in many of the species; the sides slightly strangulate at the apex, slightly and roundly dilated to the posterior carina, thence obliquely narrowed to the base ; posterior carina widely interrupted in the middle (in proportion), concavely curved at each side of that interruption, thence rather obliquely directed upwards to the sides, where it is semicircularly rounded, afterwards subsinuately directed towards the apex, where it is lost in the two obsolete transverse wrinkles beneath the apex, the uppermost of which is obsoletely continued (like a margination) upwards and downwards. Scutellum more or less transverse, generally at least twice as wide as long, sometimes only one-half wider, but in this last case it is one of the most transverse in the genus. Elytra broadly depressed on the disc, but less deeply than in Pt. de¬ pressus , the depression reaching the fourth stria ; base of each very obtusely rounded, conjointly emarginate in the middle, widely rounded at the sides, where the shoulders are oblique and slightly callose ; its margination forms a sort of fold, wider in the middle. The sides are, in the most developed males, evidently most narrowed towards the apex (as in Pt. nebulosus , 01., and Pt. depressus , Jekel) of any of the species, and those of the small males and of the females are as much narrowed as in the males of the other species. They are certainly the most elongate in the genus, being nearly twice and a half as long as broad in the middle : they are also less convex 48 INSECTA SAUNDERSIANA. on the disc longitudinally, being straightly horizontal from the base to four-fifths of their length, then very slightly declining to the callosity (hardly 35°), the declivity being evidently less than in any other species of the genus: this is one of the most important of its distinctions from the allied Pt. Columbianus , tricostifrons and nebulosus. The ante-apical cal¬ losity is broad at the base, conic, acute, extended horizontally beyond in large males, or at least to the perpendicular level of the apex, which is perpendicularly, subemarginately and very shortly cut under that callosity: this is best observed when the insect is seen from the side. The basal ex¬ tension of the callosities, conically porrected behind, gives to the elytra the appearance of being emarginate between them, when seen from above. Body beneath the flattest and least thick of the genus: obsolete ma¬ cular denudations are often observable at the base of the three posterior segments of the abdomen, which is generally widely denuded along its middle. Legs : — thighs very short proportionally to those of the species in the second group : intermediate not attaining to the base of the posterior ; the latter reaching only the third part of the third abdominal segment.

Typ. in Mus. Dorn. Chevrolat). Patria : Cayenna. — Dom. Olivier, Mus. Chevrolat — Dupont, Mus. Jekel. According to a typical specimen from the Oliverian collection, in the possession of my obliging friend M. Chevrolat, the insect above described is the true nebulosus of that author, although the description certainly agrees not only with this, but with the preceding and the three following species, as well as with some others. But Olivier’s figures, and especially that of the male, better represent this specie^ than any other, in the shortness of the body, combined with the narrowness of the elytra, although the elonga¬ tion of the subapical callosities is exaggerated. From the narrowness of the elytra posteriorly, especially in the large males, it much more nearly resembles Pt. elongatus than the two following species, but it is proportionally much shorter, more so than Pt. Columbianus , not so much so as Pt. tricostifrons. The depression of its elytra is shallower than in the former and the latter, but somewhat less than in Pt. Colum¬ bianus. The coloration of its body beneath is of a greener white, the common band of the elytra is darker (light fulvous, subferruginous, rarely whitish), its borders less indicated on the lateral ground, which is of a lighter fuscescent tomentosity, and more mixed with the fulvescent colour of the band, the emarginations of this being only darker and hardly mixed. Head shorter than in the above-mentioned species {Pt. tricostifrons excepted), transverse ; front at least as convex as in Pt. Columbianus , con¬ sequently evidently more so than in Pt. elongatus. Eyes as convex as in Pt. tricostifrons. Rostrum as robust as in that species. H 50 INSECT A SAUNDERSIANA. Thorax as much broadened as in the last-mentioned species, but more widely and shallowly depressed, exactly as in the two others, differing from these only by being proportionally shorter. Elytra less deeply emarginate at the base than in Pt. elongatus , and not subrotundate at the middle of each, but subtruncate from the scutellum to the angles of the thorax, thence hardly deviating from that line to the shoulders, which are obtusely rounded ; sides in the large males more narrowed towards the apex than those of the largest size in Pt. Columbianus and tricostifrons , but some¬ what less than in Pt. elongatus , though perhaps more so if we consider that they are proportionally much shorter, being only twice as long as at their median breadth. Their depression is less than in Pt. Columbianus , but their straightness, seen from the side or in profile, is nearly the same, with this difference, that they are in both sexes shorter, but their posterior declivity is more oblique. From their shortness, their lateral thickness, as well as that of the body beneath, is more evident, especially if we calculate the proportion between the perpendicular height of the insect and their length ; they are nevertheless, as well as the body, not so thick as in Pt. tricostifrons. I have seen a number of specimens of this species. Ptychoderes Columbianus, Jekel.

Very closely allied to Pt. elongatus, but it constantly differs as follows : — Body proportionally thicker when seen from the side, more parallel and less depressed in the elytra, which are evidently less straightly horizontal longitudinally, and with the posterior declevity to the callosity greater, being more than 40 degrees, more thickly, convexly and obliquely inflected at the sides. The general distribution of the tomentosity is exactly the same, but the colours are somewhat different: on the body beneath it is of a subsericeous (not cretaceous) white, exactly the colour of raw silk ; on the common band of the thorax and elytra, of a slightly rosy white ; on the sides, of a very light fuscous, or rather of a brownish hue, more mixed with the rosy colour of the dorsal band : this has its ordinary maculae a little more dusky than the colour of the sides (especially the two maculae filling the emarginations of the band), but always with a lighter aspect than in the pale specimens of Pt. elongatus. This is nevertheless of slight importance, as the real differences consist in the lateral outline, the thickness of the body and elytra, as well as in the posterior convexity of the latter. Head evidently shorter in proportion, more convex in front. Eyes less elongate, more convex and extended outwards, extending more in front towards the rostrum. Rostrum somewhat shorter and narrower in both sexes in proportion to the size of the head. Antennce in both sexes thinner, especially in the male, in which they seem to be more elongate, as 52 INSECTA SAUNDERSIANA. amongst the numerous specimens of Pt. elongatus which I have observed, no specimen possessed antennae as long as the body, while in this species they are longer. I have seen males one-tliird smaller, having these organs as long as in the large specimens. Is this species invariable in this character? Those of the females are rather longer, approaching in length nearly to the posterior carina. Thorax in both sexes shorter (the breadth in the male T80, in the female T90 of the length, also broader in proportion to the elytra, which are rather broader, less conic and more rounded at the sides, more convexly and thickly inflected at the sides, scarcely less impressed on the disc. The posterior carina is less curved at each side, and more narrowly interrupted in the middle. Scutellum proportionally longer and narrower, or (but a little broader than long) shortly ovate-subquadrate. Elytra evidently less rounded at the base of each, subtruncate, or, con¬ jointly slightly emarginate in the middle, their basal margin equal, depressed ; they are proportionally narrower at the shoulders, which are more rounded and not so much widened in proportion to the thorax and their width in the middle: the sides slightly narrowed towards the apex, which is more obtusely rounded ; less horizontal lengthwise or slightly convex from the base to four-fifths of the length, more inflected posteriorly to the callosity, which is less elongate (though also conic), and scarcely extended beyond the perpendicular level of the apex : this is, as in the preceding species, perpendicularly, subemarginately and shortly cut under the callosity. Seen from above, they are in the males less angularly emarginate (apparently) between the callosities, and in the females they seem hardly emarginate ; while in the females and minute males of the preceding they are evidently emarginate, although less so than in the large males. Abdomen scarcely denuded in the middle, showing also the denuded maculae at the base of the three posterior segments, as in the preceding. I have seen a number of specimens of this species.

Head immersed to the eyes in the thorax, transverse, a little obliquely and straightly (subconically) narrowed towards the rostrum, nearly flat, clothed with a dense light fulvous or straw-coloured pile ; convex, black, shining, transversely and finely strigose underneath. Eyes oblong, trans¬ versely very narrow, entire, lateral, not encroaching upon the head, slightly convex, brown. Rostrum more than twice as long as the head, elongate, narrow, not broader at its base than the forehead ; sides to two- thirds of the length straightly parallel, then rather abruptly obliquely and somewhat roundly dilated to the apex, with the inferior dilatation {Pterygium) under the insertion of the antennae, evidently more extended laterally than the upper one ; apex slightly emarginate ; upper part obso- letely canaliculate anteriorly, densely clothed like the head; the apical hairs reach over the tip and partly cover the labrum and mandibles ; inflected sides nearly flat, but not separated from the upper side by any lateral ridge or angle, denudate and rugose, as well as the lower part, OOLEOPTERAi 97 which has a deep longitudinal channel. Antennal groove apical, its base sublinear, longitudinal or parallel to the rostrum, short and shallow, its terminal part widely evanescent, obliquely impressed behind the pterygium. Thorax oblong, base subtruncate, very obtusely produced in the middle, sides slightly dilated from the base to the middle, then roundly obliquely narrowed to the apex, which is at least one-half narrower than the base ; apex truncate-subemarginate above, very obliquely trun¬ cated at the sides, subsemicircularly emarginate beneath ; upper part longitudinally convex, or rather subgibbous in the middle, and ob¬ liquely attenuated from thence in a nearly straight line with the head and rostrum, so as to describe, with the horizontal line of the elytra and posterior part of the thorax, an angle of about 45® ; the under part is straight, horizontal, like the posterior upper part and the elytra, so that it is diminished to more than half the thickness at the apex ; disc depressed along the middle, with a median ridge obsolete at the base and tip, and a dorsal elevation on each side of the depression, convex, rugose ; sides finely, under part evidently, rugose; clothed with a fulvescent grayish pile, more condensed at the sides, and especially in a lateral line on the disc, forming a lateral margin, and attaining inwards to the dorsal elevation, which is denudate as well as the median ridge. Posterior carina as described in the generic characters. Scutellum scarcely transverse, ovate-subquadrate, densely clothed with fulvous pile. Elytra oblong-subquadrate ; base conjointly sinuately subemarginate’ obliquely dilated from the angles of the thorax to the shoulders, which are rounded and callose ; sides exactly straight near to the apical declivity and tubercles, where they are abruptly narrowed or very obtusely rounded ; transversely convex ; inflected margin sinuate, slightly roundly dilated behind the base, emarginate near the middle ; longitudinally and obliquely elevated behind the base, then nearly straight, scarcely convex to five-sixths of their length, then very slightly attenuated to the ante-apical tubercles, but subperpendicularly truncated behind them ; punctate-striate, the punctures approximating, rather deep and large, especially near the base; interstices convex, rather narrow, obsoletely and finely rugulose, intra- sutural and 2nd elevated at the base, forming on each elytron with the shoulder three basal elevations between which the remaining areas are 0 98 INSECTA SAUNDERSIANA. impressed ; the elevation of the second interstice is continued longi¬ tudinally in a more evident convexity than the other interstices: elytra depressed along the suture to two-thirds of the length ; the ante-apical tubercles are three in number on each elytron, the median being the most elongate, acute, but not attaining to the perpendicular level of the apex, which is not quite, though nearly, perpendicularly truncated : they are slightly scattered with thin fulvous grizzly pile, showing the pitchy ground¬ colour : they have a basal light fulvous lineola inside the shoulder, and their apex is entirely clothed with a very dense fulvous-ochraceous pile, reaching above over the tubercles, where it is transversely truncated, — a character which gives them some resemblance to several species of Anthribus , properly so-called. Pygidium broad, transverse, subsemicircular, nearly flat, subperpendi¬ cular, densely clothed like the apex of the elytra. Body beneath pitchy, scattered with pile like the elytra, having the two apical rings of the abdomen densely clothed like the elytra and pygidium. Legs pitchy, scattered with pile like the body beneath.

Patria : Guinea lusitanica ; D. Bocande ; D. Deyrolle. This species very closely resembles Deut. nebulosus , Irnhoff, Sch., but M. Deyrolle having received a number of specimens of this as well as of the former, and constant differences existing between them, without any intermediate links, I consider the species distinct. Body , although varying very much in size, generally smaller, more convex and narrowed, never entirely tomentous on the thorax and elytra, but adorned with more or less connected spots, leaving large denuded patches; the tomentosily thicker than in Deut. nebulosus , and yellowish or grayish fulvous. Antenna proportionally thinner, with the second joint in the males not bisinuate, as in Deut. nebulosus , but nearly straight, not so broad, and not gradually widened towards the apex ; indeed subequal in width from the base nearly to the apex, and much more abruptly and shortly (subtriangu- larly) clavate. Rostrum evidently shorter in both sexes. Thorax narrower, less widely depressed on the disc, more strangulated and subtubular at the apex, which is less deeply emarginate in the middle ; posterior ridge, although sinuated, much less distant from the base at its sides, and scarcely interrupted in its middle. Elytra proportionally more convex, elongate and parallel ; shoulders more angular and callose ; strise having their punctures more distant and deeper, and the interstices with more distant and coarser rugosities, &c. Obs. — M. Deyrolle first proposed for this species the name of Decata- phanes pictus. It is, however, a Deutero crates, the Decataphanes of M. Imhoff being a very different genus : it is also more convenient tu apply to it a new specific term. 100 INSEC'TA SAUNDERSIANA. Genus STENOCERUS, Schbnherr. This genus has been established by Schbnherr for certain American species : the type is the Anthribus fulvitarsis of Germar. To these he has joined a species from Java, Sten. collaris, Chevr., very different in its generic character, and another from New Guinea, Anthr. Garnotii, Guer., which he had not seen, also equally distinct from that natural American genus. These two species excluded, the genus remains one of the most homo¬ geneous of the family, and, like the Ptychoderi , contains species so closely allied in shape, sculpture and general distribution of colours, that, without great care and the sight of many specimens of some of them, differences can scarcely be detected between them : their markings and sculpture being so similar, I have tried to separate them according to the relative proportions of the body, thorax, elytra, &c., with careful scales of these pro¬ portions and comparative descriptions, being the only way I found possible for their determination. Hoping that the result of my observations on their specific differences may not be useless, I introduce them here, especially as I know all the Schonherrian species, the type of S. collaris being in the collection of my obliging friend M. Chevrolat, and S. Garnotii existing in the museum of M. Guerin, — both being, as before observed, types of distinct generic forms. Stirps I.

This species is certainly the shortest of the genus, having in breadth f^ths of its length (head and rostrum excepted). It is with Sten. brunnescens the most convex ; the darkest tomentose ; its ground clothing being of a fine black velvet-like hue. Head shorter and more convex than in Sten. fulvitarsis , slightly extended behind the eyes, transversely and shallowly impressed between their hinder edge. Eyes less elongate, longitudinally convex, extended laterally, less advanced on the forehead, which is shorter and broader. Rostrum also shorter and broader than in the female of Sten. fulvitarsis , nearly one-fifth shorter than the thorax (mandibles excluded), and not longer than the head at the place of and including the eyes, more than a COLEOPTERA, 105 half broader at the apex than at the base, subcircularly narrowed at the middle of the side ; the median longitudinal ridge is rather wide and high ; the lateral ones on the disc are nearer to the sides than to the median, strongly indicated in their basal half, especially at the middle, joining the inner margin of the eye, where they are obsolete and running obsoletely, but evidently, at the same distance from the side to the apex, a character more strongly indicated than in any other species. Antennae rather thicker than in Sten. fulvitarsis, but their two basal joints are more thickened, and the first is rather thicker and longer than the second. Thorax hardly as wide as the elytra, less conic than in Sten. fulvitarsis, its breadth in front being scarcely more than half of the posterior width ; the sides not so deeplp bisinuate, but the posterior lobe is narrowly sub- acutely rounded, and the anterior is subangular ; the disc is hardly impressed anteriorly, and shallowly depressed posteriorly ; the tomentosity is of a fine velvet-like blackish hue, having a figure nearly resembling the half of an elongate hexagon, formed of a fulvous- ochraceous tomentosity. Elytra much shorter than in Sten. fulvitarsis and all the other species, more convex, less depressed anteriorly, with the suture and alternate inter¬ stices evidently elevated; clothed with a fine velvet-like blackish pile; the disc has a large common patch of a fine fulvous-ochraceous hue, occupying all the basal part, except the shoulders,- each side strongly obliquely emar- ginate, narrowest between the 3rd and 4th striae, nearly at the middle of the length of the elytra, then abruptly transversely dilated, reaching the sides of the disc, and slightly truncated behind the dilatation at two-thirds of the length of the elytra upon the declivity ; this large patch nearly re¬ sembles the outline of a tortoise walking, or a Cassidce. The suture and alternate interstices are tessellated with black holosericeous maculae, rather distant, but more numerous and extended on the disc than in Sten. fulvitarsis. Body beneath and legs finely punctate, black, slightly clothed with black tomentosity, partly shining and scattered over with extremely fine and short grayish pile, hardly changing the uniformity of the black ground; tarsi with the two first joints (and the third partly) densely clothed with a fine fulvous pile. All the other characters are as in Sten. fulvitarsis. 106 INSECTA SAUNDERSIANA. Stenocerus longulus, Jekel.

Patria : Brasilia, Dorn. Dupont. This species is rather smaller than the largest specimens of Sten.ful- vitarsis , but it is much narrower, being the most elongate and parallel of the genus. The thorax is less shortened, less dilated at the sides pos¬ teriorly, the central longitudinal elevation more indicated, and descending nearer to the base ; it has three fuscous spots placed in a transverse row above the middle, and the elytra are much more elongate and convex and subparallel, independently of the different colour. Head subperpendicular when at rest, longer than wide, a little shorter behind the eyes than between them, convex (in Sten. fulvitarsis it is nearly flat), subimpunctate, with a short thin longitudinal canal on the middle of the vertex, leaving an interruption between it and the rostral ridge which runs behind the forehead, covered with a light fulvous pubescence, condensed in a yellowish hue round the eyes and in the posterior canal. Eyes generally brown, sometimes pitchy, ovate, subtruncate anteriorly, placed longitudinally subobliquely, narrowing the forehead towards the rostrum, slightly convex. Rostrum nearly one-half longer than the head, and much narrower at the base, proportionally shorter and narrower than in Sten. fulvitarsis , with the sides straight from the base to nearly one-fourth of the length, then obliquely dilated, and still more abruptly so towards the apex, where it is one-half wider and nearly as broad as the head at its base ; apex sinuately truncate, with its sides shortly obliquely truncated ; flat, especially near the tip, where it is shallowly impressed, having a raised glossy longitudinal ridge along the middle, somewhat . widened and depressed at the apex, and two other short thin and lower ridges, one at each side of the median ridge, nearer to it than to the sides, COLEOPTERA. 107 running from a little above the eyes to the middle ; black or pitchy, dull, finely punctulate, except the tip of the median ridge, which is more coarsely and distantly punctate and shining ; base clothed like the head, the remainder glabrous. Antennie proportionally thicker in both sexes; 2nd joint oblong-conic, evidently longer than the first. Thorax less convex, anteriorly, less deeply sinuate at the sides ; pos¬ terior carina less roundly produced downwards in the middle, less emargi- nate near — and less rounded at — its sides, which are subangular, less roundly dilated above its supposed posterior lateral angle, leaving there the thorax evidently narrower than the elytra, and, as these are much nar¬ rower than in 8 ten. fulvitarsis, certainly much more angustate than in that species; the carina is also more slightly emarginate at the* sides, and less widely produced laterally, and, instead of having this second lobe suban¬ gular and raised at two-thirds of the length, it is obliquely rounded, slightly elevated, terminating nearer to the apex: the median elevation of the middle is narrowly continued to the base, the basal central depression being divided by it: the pile is much lighter, yellowish fulvous, and the spots, instead of being fuscous, are brown, and there is above the middle of the disc a transverse row of three spots, the middle one only per¬ ceivable in Sten. fulvitarsis: these three spots are sometimes obsoletely indicated as well as the two ordinary apical and the intra-lateral line of each side. There is, moreover, behind the intra-lateral fuscous line, some¬ what above the middle of the side, a punctiform yellow spot wanting in that species, but observable in many of the following. Scutellum subquadrate, clothed with light fulvous pile. Elytra subparallel (the most parallel and elongate of the genus), very slightly narrowed behind, much less widened at the base, and much more elongate than in Sten. fulvitarsis, less widely impressed on the disc, with the lateral depression less obliquely directed inwards, shallower, the oblique elevation running from the shoulder separating it from the median impression, less indicated and oblique. The ground-clothing is brownish, the suture and alternate interstices convex, irregularly clothed with yellow pile, condensed on each side of the base within the shoulders into a large macula or patch, and behind the middle into an interrupted subfulvescent transverse fascia, nebulously circumscribed ; the suture and interstices tessellated with rather distant fuscous blackish spots, more indi¬ cated on the middle of each elytron, so as to appear as a clouded blackish patch. 108 INSECTA SAUNDERSIANA. Body beneath having its pile of a light ashy brown, more or less mixed with yellowish. Legs proportionally more slender, having their ground pile much lighter ; not only the tarsi, but also the tibiae nearly entirely (base excepted) and the thighs partly clothed with a yellowish fulvous pile, rarer, and of a less fine texture on the tarsi than in Sten. fulvitarsis.

This species is extremely allied in coloration and general outline to Sten. long ulus, Jekel; it, nevertheless, differs in having the constant fol¬ lowing differences: — The size is always smaller, and it is proportionally shorter : the ros¬ trum and head are shorter from the hinder edge of the eye to the apex, being together shorter than the thorax ; this is evidently less trans¬ verse and proportionally longer: the elytra are shorter, not only absolutely, when compared with those of that species, but also in proportion to the thorax and their own breadth, &c. : 'the second joint of the antennae is not evidently longer than the first, and is only ovate-conic ; their funiculus is also thinner. The insect has, moreover, an indescribable different aspect joined to the above-mentioned differences. COLEOPTERA. 109 * Stenocerus Mexican us, Jekel.

This species, closely allied to Sten. migratorius in coloration and size, is proportionally more robust and convex, and less elongate. Having seen a large number of both species, I have found the following constant differences : — The present species is proportionally still broader and shorter, espe¬ cially in the elytra ; these are more depressed in the middle, but less so at the sides ; the oblique elevation running from the shoulder is more abruptly and obliquely directed inwards ; they are more evidently narrowed towards the apex, more so than in any other species in this group, and they are thicker and more obliquely slanting posteriorly : the thorax is more convex, narrowed and elongated proportionally, indeed less conic, although as deeply bisinuate at the sides ; the anterior lobe is more angular and less ob¬ lique ; its median elevation is obsolete from a little behind the middle to the base, so that the basal depression is entire and deeper : the rostrum is less flattened at the apex and more elongate, &c.

Patria : Carthagena, Columbise, Dom. Dupont (Lebas). This species also resembles Sten. migratorius and Sten. Amazonce ; in its proportions and size it is more allied to the former, but is generally smaller. The thorax is nearly as conic, its second (anterior) lateral lobe is as oblique as in Sten. migratorius , but it is more convex, though less so than in Sten. Amazonce ; its posterior depression is smaller, shallower than in both, and the anterior median elevation is nearly obsolete, or, rather, each side of this longitudinal impression is so obsolete that the anterior convexity is scarcely divided into three longitudinal elevations, as in those species ; the fuscous spots are placed in the same manner, but inde¬ pendently of the two lateral punctiform spots (one on each side above the middle) there are two others on the disc, altogether forming a transverse row of four spots ; there are also two others on each side of the disc above the base, and a duplicate fuscous one between these: the elytra are less shortened, widened and convex than in Sten. Amazonce, nearly as narrow posteriorly, but more so than in Sten. migratorius and Sten. mexicanus : above all, they are, with those of Sten. brunnescens , less depressed along the suture and at the sides, and consequently the most apparently and most 112 INSECTA SAUNDERSIANA. regularly convex, not only of any of the species of this group, but also of the whole genus ; their fulvous mixture (as well as that of the thorax) is lighter than in the three preceding species, and the large nebulous dark patch formed with the blackish tessellations at the middle of the elytra is much better indicated and circumscribed than in the preceding, the flaves- centpile of the alternate interstices being nearly wanting in that part: the tarsi have their first joint only densely covered with a yellow pile, and the second and third are nearly denudate; the terminal is slightly scattered over with thin short yellowish hairs, showing the ground. It varies also in being sometimes not more than one-half the ordinary size. * Stenocerus brunnescens, Jekel.

Patria: Carthagena, Columbiae, Dom. Dupont (D. Lebas?): Mus. Jekel. This interesting species is one of the most distinct of the second group. Its elytra are as parallel as, though much shorter than, those of Sten. longulus , and were it not for its habitat I would have placed it immediately after that species. Nevertheless, by the slight depression of the elytra at the suture and sides, especially posteriorly, where these organs are regularly convex, it has a somewhat natural connection with Sten. tessellatus. The only specimen I know is nearly as broad as Sten. longulus , but much shorter, the parallelism of its elytra is still more evident, but extends only to two-thirds of the length, and afterwards the sides are more abruptly roundly narrowed towards the apex than in any of the other spe¬ cies. The posterior declivity of these organs is more perpendicular than in its allies : the thorax, nearly shaped as in Sten. longulus , is less trans¬ verse, or rather, more elongate, since it is not narrower in proportion to the COLEOPTERA. 113 elytra; it is very slightly emarginato-sinuate by the prolongation of the posterior carina at the sides, the anterior lobe of which is very slightly ob¬ lique, subangular ; the apex is proportionally less narrowed than in all the other species, except, perhaps, Slen. testudo , with which it has another point of resemblance, — the obtuse narrowing and the regular convexity of the hinder part of the elytra. The general colour of the body is lighter than in any other species of the genus, being brown or dark rufous ; the ground-clothing is of a light brownish chocolate hue, darker beneath. The thorax is rather densely mixed with whitish yellowish. The elytra have the ordinary basal patches and the posterior fasciform nebulosity formed of whitish pile ; and the tessellations of the suture and alternate interstices, which are slightly convex, are of a darker brown alternated with obsolete whitish dots, only observable on the suture. The body beneath and legs are mixed with a minute distant white pile, and the first joint of the tarsi only is densely clothed with light fulvous hairs ; the other joints have a pale pile slightly scattered over them. * Stenocerus frontalis, Sch ., Gen. et Sp.

This species is extremely close to Sten . varipes of Schonherr; it is larger ; its males are larger and broader proportionally than the females of that species : the rostrum is less deeply emarginate in the middle of the apex : the thorax is proportionally more elongate and less angular at the Q 114 INSECTA SAUNDERSIANA. sides of the posterior carina ; the elytra more rounded at the base, more convex, broader proportionally, and more abruptly and obtusely rounded to the apex. All these characters, if they were not evidently such in the male, compared with the female of Sten. varipes , would be sexual (that is feminine) in the same species ; they however exist in these proportions in each sex of both : I, therefore, think the present insect to be specifically distinct.

This species is as nearly allied to Sten. varipes , Sch., and Sten. verti¬ cals , Jekel, as the species of the second group between them ; it is half the size of Sten. varipes , and is the most minute of the genus : the thorax is longer in proportion to the elytra, its two longitudinal canaliform impres¬ sions are shallower, the lateral angle of the posterior carina is more angu¬ lar, and the sides, yet straighter, are more obliquely narrowed to the apex : the elytra are, in proportion 4o the thorax, shorter, they are less flattened along the suture, evidently more narrowed towards the apex ; their light tessellations are whitish, their disc is more mixed with white : the body beneath and legs have their light mixture whiter, and the first joint of the tarsi is of a milk-white hue : the rostrum is also less widened to the apex than in these two species. Of this Lilliputian Stenocerus I have seen only one male specimen. Its antenna are much longer than in all the males of the other species* COLEOPTERA. 115 reaching much beyond the base of the elytra, and their second joint is pro¬ portionally shorter, not regularly obconic, but abruptly globular at the apex, very slender at the anterior part, whereas it ought to be more elon¬ gate and less inflated at the tip, according to the elongation and slender¬ ness of all the other joints. There is a tendency to that inflation in the two preceding species, but in a much slighter degree, combined with greater elongation, as in the other species. Stenocerus nigrotessellatus, Blanchard, (d’Orbigny, Voy. dans l’Amer. Merid. 1837—43, p. 200, No. 636, tab. xvi. fig. 2). A very fine and large species, extremely allied to Sten, testudo , in its coloration, but larger (size of Sten. fulvitarsis ), proportionally more elongate in the thorax and elytra, the former having the anterior lobe of its sides more acutely produced above, the latter are less depressed along the suture and at the sides : the thorax is likewise adorned with a semi¬ circular ochreous line, and the ochreous dorsal patch of the elytra is of a finer and orange hue, on which the black tessellations are much more numerous on each row, and consequently more nearly approached each other. Its place is between Sten. fulvitarsis and Sten. testudo , in the first section, of which it has the proportions of thorax and elytra in a lower degree, and it links this section to the second.

This large and fine species is about the size of the largest specimens of Slen. fulvitarsis ; it is very close in outline, convexity and depression of the elytra to Sien. longulus , but proportionally broader. Its thorax is the least conical of any species known by me, the posterior lobe of its sides is regularly semicircularly, the anterior is widely and very obtusely rounded : the elytra are abbreviated as in Sten. brunnescem , and hardly more angustate posteriorly : the colour of the tomentosity of the middle of the thorax and the ordinary common patch of the disc of the elytra, is of a fine dense ochreous hue ou the latter, but nebulous, pale and rare on the former ; the black macula filling the lateral emargination of the dorsal patch is of a fine blackish and very dense, widely extended laterally : the first joint of the tarsi is densely, the second less fulvous-spongiose ; its place is at the beginning of the second section, before Sten. longulus , in consideration of its large size, though nearer to Sten. brunnescens , in the shape of the elytra ; by its thorax much less conically narrowed ante¬ riorly, it is easily distinguished from all the other species. There are four insects described by M. Blanchard, in Gay’s Hist. Natur. de Chile, under the generic appellation of Stenocerus , none of which are allied to this highly homogeneous genus. One, Sten. minutus , Blchd., loc. cit. Zool. v. p. 298, No. 2, is a minute insect of the size and shape of Tropideres undulatus , with which, in the form of the antennae and rostrum, and in its eyes small, round, semiglobose, lateral, not extending on the forehead, which is broader than the base of the rostrum ; it must be arranged close to Enedreytes, Sch. The second, Sten. asperatus, Blclid., loc. cit. Zool. v. p. 298, No. 1, close to the preceding in the character of its antennae, rostrum and eyes, but nearly double the size, and having the elytra tuberculated. It resembles Tropideres sepicola , which, like Trop. undulatus , has no other resemblance with the remaining European Tropideres , in which the “ eyes are large, flattish, nearly entirely placed on the forehead, which is much narrowed by them, especially towards the rostrum,’’ than the minuteness of the size. The last two species, Sten. signatipes, Blchd. (Zool. v. p. 299, No. 4) and Sten. tuberculosus, Blchd. (Zool. v. p. 299, No. 3, pi. 22, fig. 2) should naturally be placed near Ischnocerus , of which they have the rostrum and moderate sized lateral eyes, but they are generically distinguished by their having the antennas shorter and much thicker in both sexes, those of the male reaching only a little beyond the middle of the elytra in the most COLEOPTERA. 117 developed specimens, for, as I have observed, these organs would vary, as in the male Ptychoderes , according to the degree of development of the individuals. Both species have a common character, uniting them more closely together ; the lateral spiniform tubercles of the base and the apex of the elytra. Genus GYMNOGNATHUS, Sch.

This species closely resembles the Crat. thoracicus (Chevr.), Sch., of the same country, and also the Crat. lunatus, Fabr., of the United States but it is larger than the former, and proportionally much broader in all the parts of the body than both.1 * Its general coloration is that of the latter, having the same tessellations and the black ante-median spot of the elytra; but the head, rostrum and sides of the thorax are destitute of the lighter tomentum observed on that species and on the former. Head and rostrum rather wide, as in Crat. lunatus, much wider than in Crat. thoracicus ,3 only moderate punctate-ruguiose, uniformly light 1 The Crat. thoracicus is said by Schonherr to be of the size of Crat. lunatus , but this is only true in small specimens, which reach to the size of the largest ones of that North American species, but many others are one-third larger. The present species reaches to a still larger size. a The head and rostrum of Crat. thoracicus are much narrower and longer than in Crat. lunatus , though the elongation of the whole body be but little more indicated. 128 INSECTA SAUNDERSIANA. brown pilose. Eyes not so large as in the latter, more rounded, but larger and more prominent than in the former. Antenna having their funiculus more slender than in Crat. thoracicus, having the same proportions of thickness as in Crat. lunatus ; rufous, with the two anterior joints of the club darker, and the third or ultimate light fulvous tomentous. Thorax subconic, proportionally broader and shorter than in these species, being evidently a fourth shorter than the basal width ; apex widely rounded ; sides obliquely ampliate to the base, a little rounded behind the middle ; base sinuous, with the posterior carina still more sinuate, applying to the elytra, when at rest ; its posterior angles are very acutely produced backwards, enclosing those of the elytra, whence it is directed forwards along the sides to the middle, where it subabruptly ceases. Disc pulvinate, depressed behind and also along the middle, with a thin deep sulcation, dividing the gibbosity (the top of which is placed above the middle) into two parts: ground-clothing light brown, mixed with small flavescent dots and some fuscous or blackish spots; sojne of these large, especially two behind the apex, not more distant from each other than from the side, and the others basal, one in the middle, smaller than the others, sometimes obsolete, and one on each side, about midway between the middle and the side; there is also a whitish longitudinal line extending from the middle of the apex, reaching at least the third of the length, and there diverging abruptly and subtransversely, each branch by a slight obliquity, running down to the middle of the length about midway between the middle and the side. Scutellum rather small, subsemicircular, or rather shortly transversely ovate, whitish piled. Elytra shortly ovate, subparallel ; base of each very obtusely rounded, not broader than the thorax ; shoulders within, but close to, the posterior angles of the latter ; sides scarcely dilated from the base to the two-fifths, thence also very slightly narrowed to four-fifths, afterwards conjointly subsemicircularly rounded to the apex, where they are shortly and slightly emarginate, when seen backwards ; the ordinary subbasal tubercle obsolete, regularly punctate-striate, with the alternate interstices convex, the inner¬ most stronger; a slight deplanation along the suture; densely covered with a light brown pile, nearly uniform on the flat interstices, tessellated with alternate flavous or whitish and dark fuscous dots or short lines on the con¬ vex ones ; the innermost convex interstice (between the 2nd and 3rd striae) adorned a little above the middle with a fuscous spot, larger than the COLEOPTERA. 129 others, nebulously extended outwards to the next alternate convex inter¬ stice, to which spot there is connected above, a whitish or flavous lineola, also larger than the others, but limited in breadth to that interstice. In some specimens these maculae are hardly larger and more distinct than the other tessellations. Pygidium rather short, only subsemicircnlar, subperpendicular, uni¬ formly covered with light brown pile. Body beneath of a lighter hue, nearly fulvous. Thorax and pectus with rather strong, deep and distant; abdomen with slight, small approxi¬ mate, punctures. Legs light fuscous, clothed like the body beneath ; thighs behind the middle and near the apex ; tibice at the base, above the middle and near the apex, annulate, with light fuscous pile : these annulations are some¬ times obsolete.

Its ordinary size is that of Crat. lunatus , but it attains sometimes that of a moderate sized Anthr. albinus, and is often reduced to that of Tropid. sepicola : there are 130 INSECTA SAUNDERS1ANA. varieties of which the ground is ferruginous or rufous ; others are pitchy black. Schonherr having had incomplete specimens, and having also omitted various particularities, I think it necessary to add the following: — Antenna slender, reaching to the base of the thorax ; funiculus 8-jointed, pale rufous or testaceous. Club large, somewhat shorter than the funiculus, 3-articulate; joints separate; 1st triangular, dark fuscous or pitchy ; 2nd shorter, transverse, subconic, light fuscous ; terminal the longest, shortly ovate-acute, pale yellow or whitish. Thorax nearly subconic, wider than long; base bisinuate, with the middle and the angles acutely produced ; posterior carina following the outline of the base, and running very close to it, applied to the elytra when the insect is at rest ; sides roundly angustate to the apex, which is roundly produced in the middle, and nearly twice as narrow as the base ; convex, subgibbous in the middle, transversely impressed behind the apex above the gibbosity, covered with fuscous pile, upon which there is a rather thick light fulvous pile, subflavous and more dense round the apex ; adorned with three basal fuscous spots, one central linear, the others at each side of this, broad at the base ; subconically elongate ; to these are subjoined three others placed above them in the middle, sublinear ; they form together three interrupted lines more nearly approaching above ; between the two spots in the middle is a subcentral pale yellow point ; an apical whitish line having on each side a pale fuscous macula, and an oblique line also whitish or yellowish, placed above each of the lateral lines in the middle, are also observable. Elytra widely and very obtusely rounded at the base ; convex, with a slight depression along the suture ; having a subbasal callosity upon which the 1st stria is duplicated, and the 2nd and 3rd obliquely driven outwards; covered with a fulvous yellowish pile; tessellated with fuscous and pale yellow or whitish pubescence, alternately placed upon the alternate inter¬ stices and the suture : of these markings two elongate fuscous ma culae or lineolae, between the 2nd and 3rd and the 4tli and 5th striae, and the fus¬ cous part of the basal callosity are more conspicuous and placed in a square. When the elytra are rubbed, the tessellation is very obsolete, the ground-colour becomes grayish, and leaves the subbasal callosities and the place of the central fuscous lines denuded, forming four black spots.

Eyes large, subcircular, but narrowly and angularly emar- ginated by the lateral ridge of the rostrum ; subconvex; two-thirds of their transverse diameter are superior, so as to reduce the breadth of the front to only one-third ; finely and regularly reticulated, rufous, reflecting a shining fiery lustre. Rostrum extremely short, broad; apex sinuated, subtruncate ; sides roundly dilated towards the eyes, which are emarginated by their acute ridge; flat, punctate-rugose; colour and pile similar to those of the head, with the sides denuded, impressed above the eyes.

Thorax transverse, nearly one-third shorter than the width of its base ; apex truncate, narrower by one-third ; sides roundly dilated towards the middle, thence slightly emarginated before the posterior angles, which are produced laterally, but obtuse ; base slightly sinuated, appearing to be margined by the posterior ridge, which is very close to it, and is angulated at the side, nearly confounded with the true angle, but separated, thence forming the margins of the sides for two-thirds, where it finishes, leaving the apical third without the carina ; upper side most convex transversely, especially on the anterior part, which is subpulvinate ; there is a little im¬ pression above the middle of the base; punctate-rugose, black, covered with a grayish fulvous pile, here and there yellowish or subochreous, condensed at the middle and base in several lighter punctiform spots, leaving also some indistinct denuded places, of which two short thin oblique lines at each side of the basd are the best indicated and circumscribed. Scutellum transversely subovate-quadrate, clothed with a yellowish fulvous pile. Elytra oblong-subparallel, nearly thrice as long as the thorax, together half the width of their length ; base very obtusely rounded, marginated, basal margin somewhat continued behind the shoulders, which are obso- letely callose and placed within the thoracical angles ; sides parallel from the base to three-fourths of the length, then roundly narrowed towards the apex, which on each elytron is slightly emarginate, with the sutural angle acute, subspiniform ; most convex transversely; there is behind the base a transversely subrhombical elevation, of which the sides, and particularly the angles, are evanescent, the supposed basal angle being cut away by the base of the elytra and the scutellum ; the supposed posterior angle also cut away at the suture by a transverse impression, placed at one-third of the length ; they are from that impression to the apex longitudinally regu¬ larly convex, without any other transversal or longitudinal impression ; they also have no callosity above the apex, and are remotely punctate- striate, the innermost stria duplicated at the base upon the gibbosity, its ex¬ ternal brauch ejected obliquely outwards, ejecting in the same manner the other striae ; suture and alternate interstices slightly convex, the remainder COLEOPTERA. 133 flatter, all obsoletely punctulate ; black, covered with a fulvescent-brown pile and two large whitish markings ; 1st, on each elytron a subrectangular triangle, indistinctly circumscribed, having its longest (or basal) side longi¬ tudinally placed outwards from the base at the shoulder (which it partly covers) to the middle, following obliquely inwards the undulation of the shoulder and the 6th stria from the base to the middle of its length where it reaches the 5lh, which it follows towards its posterior angle; from this it runs obliquely upwards to the suture at the gibbosity over the impression, where it meets the corresponding marking, forming there its geometrical apical angle; the figure then varies from the above form, for the last side is very irregular, being first transverse, cutting with the cor¬ responding mark the gibbosity above the impression, to which it is parallel, clothed with a thin fuscous pile, then after this transverse emargi- nation it is angularly widened towards the base very near the scutellum? encircling the supposed anterior side of the gibbosity ; this is covered on its basal half with the brownish pile of the ground, which forms there a truncate triangle ; 2nd, a common fascia, wide, very obliquely and sinuately directed anteriorly from the margin at two-thirds of the length upwards to the 2nd stria somewhat behind the middle, then transversely cut to the suture, being clothed with a fuscous pile here and there condensed in spots, posteriorly confounded with the brown colour of the apex: we might suppose indeed this large common patch to be an irregular triangle, of which the apical angle is cut away at the suture, and the lateral directed and lost beneath the margin: Pygidium semiovate, densely clothed with a fulvous long and thick pile; middle longitudinally and narrowly impressed. Body beneath densely and finely punctulate, covered with a yellowish gray pile, thicker and lighter on the sides of the pectus, rarer, thinner and subfulvous under the thorax. Thorax beneath obliquely shortened from the sides to the middle ; apex nearly regularly circularly eraarginate, with a rather broad margin deeply impressed ; base also emarginate, but at a distance from the sides ; longitudinally convex, with an impression near the base, at first transverse from beneath the coxae to a certain distance from the side, but gradually more removed from the base (this being oblique by its emargination), it is there angulated, and afterwards obliquely directed to the posterior angle.

I am indebted to Mons. H. Jekel for the descrip¬ tions of Gurculionides in the following pages, which form a continuation of the ‘ Insecta Saundersiana.’ My original plan has been slightly departed from, by allowing the Author to introduce the characters of a few species not in my collection, chiefly with a view of bringing nearly allied species together : these are clearly designated in the text by an asterisk prefixed. W. WILSON SAUNDERS. Hill Field , Reigate. March, 1860. INSECTA SAUNDERSIANA COLEOPTERA. Fam. CURCULIONIDES. PART II. Div. ATTELABID^E. I think it convenient to unite here, under one and the same head, the following small divisions of Schonherr : — Attelabides, Rhino- macerides, Apionides, Tanaonides, Oxycorynides and Antliarhinides. These divisions are not important enough in their differential cha¬ racters, and some of them are really too limited in their number of species, to be raised to an equal rank with the two groups pre¬ viously reviewed. On the contrary, when united, they have such a number of characters in common, and they are so naturally bound together in their general constitution, that they perfectly answer the ideas of natural connexion indicated by the former authors who treated of them. Should they be deemed worthy of being kept separate, they should not, at least, be removed so far from one another, as Schonherr has done it for some of them, in introducing between them the Brenthidae, a group so strikingly different that an eminent entomologist* has of * Ludwig Imhoff, c Versuch einer Einfuhrung in das Studium der Koleoptern,’ Basel, 1856 ; a very interesting work containing a great number of entirely new views regarding the classification, many of which will probably throw a great light on the subject, though in some instances, the given characters intended to limit certain groups are rather the exception than the rule. Y 156 INSECTA SAUNDEKSIANA. late tried to prove their want of resemblance to the other Rhynchopliori, by transferring them to his ‘ Coleoptera Baculicornia,’ between his Cucujidag and Parandridse. Imhoff has also proposed in the above-quoted work (ii. p. 209, section Attelabides) the reunion of most of these small groups, but I rather differ in opinion regarding the composition of this “ Section,” as well as of his other sections of Paeodognathica and Baculicornia corresponding to Schonherr’s Curculionides. 1st. I regard the Camarotides as requiring to be transferred to the vicinity of Prionomerus, Ctenomerus, Pristimerus, and many other short-nosed Mecorbyncbi (!) of Schonherr, whose anterior femora are extremely ampliate and denticulate inside, genera that are so different from the majority of Erirhinides, Sch. The antennae of Camarotus are really geniculate, their scapus is hardly shorter than in the above-cited genera, and the groove of its rostrum is elongate, oblique, can aliform ; the armature of its anterior femora still more increases this presumption. It might very likely be possible, in joining to these all the Schonberrian Curculionidae Gona- toceri whose pygidium is exposed, to form a large special subdivision, divided into as many groups as should be necessary for their natural distribution.* Then, we might see Magdalinus and Lagmosaccus, &c. ; Nerthops and Pristimerus, See.; Phytobius, Cceliodes, Ceutoihyuchus, and their aberrant genera ; Lamirus, Coryssomerus, Dorasomus, &c. ; Germar’s Pcecilmas or Zygopides, many Cholides, Baridides and Cionides, &c., exhibiting a vast and natural assemblage of genera so very different from — and really equal in rank and value to — the remaining Mecorhynchi of Schonherr (Calandridse and Cossonidae of course included). 2nd. Ulocerus, I regard, with Irahoff, as properly belonging to the Brenthidae, by having similar sexual differences in the rostrum, the same station of antennae, as well as a similar constitution of the two basal rings of the abdomen, &c.; but Episus cannot be removed from Bracliyceridae, although wanting a channel in the antennal groove of * V. Jekel, Bull. Soc. Entom. France, 1855, p. xxvi. Gerslaecker, Bericht, &c., fur 1855 (1857), p. 75. COLEOPTERA. 157 the rostrum. This genus very much agrees with Microcerus, in the construction and station of its non-geniculate antennae ; it also shows no sexual difference in the shape of the rostrum. The two anterior rings of the abdomen are constructed just as in that group, as well as in many of the Curculionideous epigean species, and, indeed, Schonherr was right in uniting them in his former work (Curculionid. Dispos. Method, pp. 8 and 78). 3rd. I rather admit of the Antliarhinides being better placed amongst the Attelabidae than with Erirhinides, as Imhoff (loc. cit. ii. pp. 210 and 217) proposes. At least, they bear a greater resemblance to some Baridides, viz., Nanus, &c. ; and by their exposed pygidium and their distant anterior coxae they rather remind one of the Apostasimerides. 4th. Oxyrhynchus evidently belongs to the Rhynchophorides or Calandrides ; the non-geniculation of the antennae being a secondary character compared to their insertion and the highly peculiar con¬ stitution of their club. Indeed, Fabricius had seen well. The Calan- dridae are so distinct from the other Curculionides, that they claim an equal rank in classification. 5th. Ithycerus is constituted so much like the Gonatoceri Bra- chyrhynchi, that I think its natural place should be there, although its antennae are non-geniculate and the antennal groove of its rostrum obliterate. 6th. Rhamphus undoubtedly is a modification of Orchestes. 7th. Tachygonus certainly is a Ceutorhynchus-like form, and has nothing to do with Rhamphus. After those eliminations, the Orthoceri of Schonherr, until now so very heterogenous, might be reduced to four well-marked types, each of them having a value equal to that of the old genus Curculio of Linnaeus, although much less numerous in species ; these should be : — 1. Brenthidae, connecting the Rhynchophori of Latreille (Curcu¬ lionides, Sch ., Paeodognathica, 7mA.) to the other Baculicornia of Imhoff (Colydii, Cryptophagides, Cucujides, Rbysodides, Parandridae and Hypocephalides, loc. cit. ii. pp. 159 — 170). Indeed, they bear a very slight likeness to the other Curculionidae. 2. Bruchidae, linking the Curculionidae to the Chrysomelidae. 158 INSECTA SAUNDERSIANA. 3. Anthribidae, a type so thoroughly distinct from the Bruchidae, that I wonder at their having been united by some authors* ** 4. Attelabidae, as I have here above proposed their modification : these really are the most connected with the Curculionidae. The remaining Rhynchophori of Latreille (Curculionides, Sch.) show only three more large types : — 5. Curculionidae, containing all the Schonherrian Gonatoceri, except 6. Rhynchophoridae, or Calandridae, and 7. Cossonidae. These really are the only constitutive types round which the rare and slight aberrations might easily gravitate, and in adding to these the Bostrichidae, as already proposed, and the Mycteridae and Rhinosi- midae, leading again to the Attelabidae (and so conveniently linking the Malacodermous Heteromera), we might perhaps be led to a classification of this important section of Coleoptera nearer to the natural one, if we ever chance to meet with it.

Elytra proportionally broader and shorter, more deeply punctate-striate, with the interstices evidently convex ; their lateral punctures under the base are fewer, larger and foveiform. Thorax beneath transversely finely, anterior coxce more strongly, strigose. Pectus deeply punctate-rugose. Abdo¬ men and pygidium more strongly punctate than in Cygneus. Apoderus Nietnerii, Jekel.

General shape and construction of both sexes as in Apod, cygneus ; much larger (especially the $ ; the single $ I have seen I regard as a small specimen) • the head is more convex ; the strigosities of the neck in the $ are fewer and stronger ; the thorax is more robust and less elon¬ gate ; the elytra more deeply punctate-striate, &c. The colour is also dif¬ ferent. The 2 bears a more striking resemblance to Apod, montanus in size, general coloration, proportion and puncturing of the elytra, but the head is more conic, elongate, much less convex ; its neck is more robust ; the thorax is less deeply emarginate at the apex, more regularly conic, the sides being straight, and its apical and basal strangulations are slighter ; the transverse strigosities underneath (as well as on the coxae) are also shallower ; the pectus is not so deeply punctate-rugose, though much more so than in Apod, cygneus . Named after Mr. Nietner, a resident in Ceylon (a zealous cor¬ respondent to our best friend and honorable president of the Entomolo¬ gical Society of Stettin), who has detected this and many other interesting species, and who has begun describing the insects of that island in his valuable entomological papers. * Apoderus collaris, Jekel.

In this subgenus I include all the species belonging to the Stirps I. of Schonherr, except Apod, scutellaris , the type of my subgenus Centrocorynus. It contains several typical forms, the principal characters of which may be briefly exposed as follows : — I. Apod, tranquebaricus , Westermanni and melanopterus are the extremes of an Asiatic group where the head is more or less oblong-subconic; the thorax conic in both sexes, or very slightly rounded in some females, obliquely strigose, canalicu¬ late, pulvinate anteriorly, with the apical margin rather deeply emarginate. The elytra are deeply punctate or foveate, their interstices are transversely rugulose or crenulate. The pos¬ terior femora are much extended behind the apex of the body. ( Strigapoderus , Jekel).

Very similar to Apod, gemmatus and gemmosus , hut quite differently coloured and tuberculate. Rostrum short, flavousor ochraceous-fulvous ; apex truncate-sinuate, with the middle narrowly — rather deeply — angularly emarginate; the two elevated ridges between the antennee prominent, black. Labrum black in the middle. Mandibulce fuscous. Antennae uniformly ochreous-fulvous. Head shortly ovate-subconical ; forehead strongly punctate, separated behind the eyes by a transverse impression ; vertex smooth, with two large approximate vittse on the middle, and another lateral, black. Thorax moderately rounded at the sides, slightly straightened to the basal striga, which is much elevated, evidently duplicate, not very broad, very slightly arcuate; slightly con¬ vex, rather attenuate anteriorly, strongly obliquely rugose-plicate, with a transverse ante-basal tubercle on each side of the middle channel, which is obsolete posteriorly; all the upper part and part of the sides underneath black, with only three ochreous subpellucid spots on the basal striga. Scutellum rather large, transverse, black, deeply punctate, with the apex smooth subbilobate-impressed. Elytra straightened at the anterior third ; dorsal part punctate-subcrenulate, especially posteriorly, the crenulations separating the punctures subtuberculiform ; sides deeply foveate ; interstices elevated, anteriorly partly — posteriorly and laterally entirely — subcostate ; humeri widely truncated, shortly spiniform ; two black tubercles on each, one at the anterior fourth, at the end of the anterior elevation of the third interstice, middling, shortly conic, the other very little behind the middle, very large, rather COLEOPTERA. 185 high, but obtuse, embracing the three innermost interstices; margin to behind the middle, irregularly — especially posteriorly — widened inside, a posterior band a little behind it, and the apex widely, black. Pygidium strongly punctate-rugose, ochreous-fulvous or flavous. Pectus strongly rugose, with the sides widely black. Abdomen coarsely punc¬ tate, uniformly ochreous- fulvous or flavous. Legs ochraceous-flavous ; femora strongly punctate at their apical third, with a subannular black macula above the apex, larger on the posterior, very small on the anterior.

Patria : Natal. D. Stevens. Mus. Bowring, Saunders et Jekel. Allied to Apod, spinosus and horridus. Rostrum transverse, very short, broad, contiguous to the head, truncate at the apex, hardly raised above the insertion of the antennae, the space between them relatively very large, punctate-subgranulate. Antennae rufous, club ample. Head broad, subconical, subplanate, subeven on the forehead with the rostrum ; an obsolete channel, two narrow supra-lateral and two broad infra-lateral lines black. Thorax rather flattened and unequal ; sides rounded ; posterior striga very broad, right, subangularly elevated on each side of the base; interruptedly canaliculate, the channel deeper and blackish posteriorly ; two dorsal coneolorous tubercles, large, conically mammi¬ form ; sides underneath with two black lines more or less circumscribed, one infra-lateral, the other close to the anterior coxae ; more slightly and finely punctate-granulate than the head. Scutellum flatlish, subinerm, or rather showing each side posteriorly a very small subtuberiform con- colorous elevation. Elytra obliquely impressed near the suture behind 186 INSECTA SAUNDERS1ANA. the scutellum and between the dorsal spines ; straightened above — some¬ what widened behind — the middle of the sides ; each obtusely rounded at the apex; shoulders subangularly directed, but with the angle rounded ; obsolete striae very sinuate, punctate subgranulose, more evidently punc¬ tate at the base; each elytron having six spines, concolor at their base, then black to the apex, of which two — one lateral under the shoulder, the other basal, on the circumscutellar emargination, not far from the suture — are shorter (^—T3g) ; the four others longer mill.) : one latero-dorsal at the fourth, another suturo-dorsal at the middle, a third latero-dorsal at the two-thirds, the fourth suturo-dorsal at the posterior fourth, of the length. Pygidium and body beneath subgranato-punc- tate ; pectus partly infuscate at the sides. Belongs, together with the four preceding species, to my Group V. Genus ATTELABUS, L. (pars), Sch. (pars). (= Attelabus, pr. diet., Sch.) This subgenus of Schonherr is very numerous* and heterogenous ; and that acute author’s subdivisions, reposing only upon the armature of the femora, are now insufficient to group the species under the several natural types they present to the investigator. I beg to propose an analytical table of the types now in my hands, completing it with secondary characters hearing on their natural similitudes and differences. Sect. I. Attelabus, strict, sens.

As such are recorded speci¬ mens collected by the late Edward Doubleday, showing the following important differences: — Generally smaller, shorter and flatter than Attel. analis ; the red-coloured parts of the body are of a subsangui- neous hue (light castaneo-rufous in Attel. analis) ; the interstices of the elytra are thinly transversely strigose (a character omitted by Kirby, who may have seen them smooth), and, in consequence, less glossy than the thorax, whilst they are really as smooth and glossy as that organ is in Attel. analis.

This variable species, well known to all entomologists, has long been regarded as the unique European species of the type it represents, and specimens from the most extreme parts of that continent, from north to south and east to west, had not been deemed worth being separated. But of late, two species have been created, — Maculipes (Villa), Kiister, and Atricornis, Mulsant. But the comparative distinctions given by their respective authors (their descriptions having not a single par¬ ticularity that could not be applied to some of the varieties of Cur- culionoides) bearing principally on differences in coloration, and on sup¬ posed proportions of width, length, size and depth of punctuation, which are just to be observed partly or entirely in various specimens of this rather polymorphous species, and their having said nothing touching the sexes, I may reasonably regard the three following at least as good species as any of those, intending to study the whole of these pretended * Attel. verrucifer. — Valde attenuatus, virescenti-cuprescens, pilis albescentibus tectus ; rostro apice valde ampliato, punctato ; capite subquadrato-cylindrico, convexo, punctato; tliorace an-tice abrupte — dein versus basin emarginatim — ampliato, basi tenue marginata apice- que late marginato oblique truncatis, dorso medio tuberculis quatuor compositis cum canalicula interjacente nonnullisque lateralibus parvis instructo; scutello medio impresso utrinque elevato; elytris subtriangu- laribus, singulo prope scutellum tuberculo composito, duabus prope suturam (uno prope medium, altero postico, mediocribus) multisque minimis disci instructo humeris late obliquae lateraliter extensis cari- natis ; femoribus muticis, tibiis infra dentibus distantibus armatis.

The differences of this species do not reside in the black coloration of the margins of the thorax and elytra — characters to be found in many specimens of the Curculionoides as well as on Alricornis, Muls., but in the shape of thorax, elytra and legs. The red coloration of the disk of the thorax hardly invades the sides underneath, is limited to the level of the margin of the elytra, and, in consequence, is hardly perceivable when the insect is viewed from beneath, a character that I have not observed in the numberless specimens I have seen of Curculionoides , in which that red coloration, more or less sinuately, approaches nearer to the coxae. The anterior flattened part of the margin of the elytra is smooth ; the legs and anterior tibiae are thinner and more elongate, especially in the $ . Attelabus hispanicus, Jekel.

This species has the thorax and elytra of a lighter rufous colour than in the lightest specimens of Curculionoides , but it is not on these differences nor on the coloration of the margins of thorax and elytra that the establishment of the species stands. The thorax is flatter, more subconically quadrate, its sides being much less rounded, according to the sexes, being in the female straighter than in the male of that species; the scutellum is more elongate, more evidently narrowed to the posterior angles ; the elytra more attenuate posteriorly, covering much more of the pygidium, at least its anterior half, and their punctuation, either serial or interstitial, is much slighter than in any specimen of that species. *Attelabus suturalis, Jekel.

The thorax is much less convex, transversely as well as lengthwise, indeed almost flat; the sides are conically, very slightly roundly ampliate towards the base ; the impression on each side of the disk is not a fovea, but a real oblique impression. The scutellum is less convex posteriorly, perhaps also less acute at the middle of its truncature. The elytra are more flatly descending to the apex ; their striae are thinner, with their punctures smaller, much more approximate, consequently much more numerous. The legs are more slender, especially the anterior femora, and the denticulations of these are much smaller. Attelabus (Hybolabus) cribricollis, Jekel.

Note. — The great number of striae in this species (as in Attel. exaratus) may be regarded as caused by a deep modification of the inter¬ stices, which are longitudinally canaliculate and punctate along their middle and costulate on each side ; these canaliculations — indeed very similar to the normal striae — are shallower and their punctures are some¬ what smaller; thence the normal number of striae (9-10) seems to be doubled.

Rostrum much shorter than the head, angularly inerassate to the apex; angularly convex, with two elevated lines diverging from the antennae to the apex ; punctate ; two unequal longitudinal strigae diverging towards the forehead, with a thick elevation between these ; forehead rather broad, impressed behind ; head longer than broad, unequally strigose-punctate lengthwise anteriorly, having a deep canali- culiforra fovea posteriorly, where it is slightly punctate, convex and smooth. Thorax with two large ante-basal mammiferous approximate tubercles and another smaller on each side of the middle ; these four tubercles glossy ; besides these, two anterior, ovate, smaller, much less glossy, strigose, are perceivable. Each elytron bears three rows of tubercles, the innermost composed of four, the median of three, the external of two. Anterior tibice of the male longer and more slender than in the female, more arcuate, the interior spine of their apex is shorter and broader, the exterior is more elongate and incurvate. Genus EUSCELUS, Germ., Sch. This subgenus of Schonherr is now rather numerous: I have seen nearly fifty species. They may be distributed in the following types : — I. Antennae breves, capite cum vostro breviores, crassae; articulis 5-8 transversim rotundatis, clava oblongo-ovata, obtuse acuta. Sculellum elevatum, transversim subquadratum. Elytra elongata, postice callosa, apice retusa, punctato-striata, emar- ginatuva scutellari obtuse transversim quadrata.

Antennae parum crassae, sat elongatae, capite cum rostro lon- giores, articulis 5-8 aut longioribus aut non brevioribus quam latis ; clava evidentius 4-articulata,* aut oblonga aut elongata. * I say on purpose “ evidentius 4-articulata,” because I am con¬ vinced that in Euscelus (even in Attelabus ?) the clava is 4-articulate : COLEOPTERA. ‘213 & 'cuteltum breviter subtriangulare, apice obtusum, parum ele~ vatum. Elytra parum elongata, postice lion callosa, rotuu- dato-declivia, seriatim punctata, punctis ssepe obsoletis aut nullis; emarginatura scutellari subtviangulari.

Typus: Eusc. armatus, Manh., Sch. Congen. : Eusc. spinifex , Oliv. ; Eusc. fornicatus , Oliv., &c. the ultimate joint small, conic, entirely jointed at its base into the penultimate, and immediately decreasing in width, very seldom shows any appearance of articulation, being concealed under the thick pu¬ bescence. This observation is certainly applicable to many other CurculionidcBy showing an apparently 3-jointed club. * Attelabus dentipes , Gyll. in Sch. (I. i. 207, No. 22) must be dif¬ ferent from the Fabrician species, for the latter says of his insect (in Diagn.): “Elytris . . . . basi uni-spinosis ; ” (in Descr.) “Elytra dente baseos valido elevato .... Caput et thorax punctata.’’ The group of these West-Indian species is to be completely revised, there existing in the collections species connecting and linking the two above recorded. 214 INSECTA SAUNDERS1ANA.

Statura formaque generalis Eusc. hamati , Sell., plus duplo major, pro ratione latior. Rostrum much shorter than the head, narrow at the base, subtri- angularly ampliate to the apex, little convex, almost smooth, with a canaliculate elevation between the antennae continuing on the fore¬ head. Head oblong, somewhat ampliate to the base, transversely impressed posteriorly, with the occiput more convex than the vertex ; obsoletely strigose-punctulate, smooth on the occiput. Eyes large, flat, approximate on the forehead, which is very narrow. Antennae rather COLEOPTERA. 215 elongate and slender, as well as their club. Thorax abruptly (S') more obliquely ( £ ) ampliate anteriorly, hardly broader than long, little con¬ vex, almost smooth, with very slight strigosities above the base ; anterior striga rather deep, little arcuate ; the median deeper, more arcuate, recurved downwards at the sides. Elytra little convex, smooth; a sutu¬ ral and a marginal striga, punctate, are the only important impressions. The basal pellucid flavous macula is very large and convex, and is im¬ pressed on the elytra nearly all round its circumference (base, of course, excepted), occupying about two-thirds of the width, and almost the basal third of the length. Thorax underneath having an oblique longitudinal striga not far from the coxae, and strong foveiform punc¬ tures at the base. Pygidium and pectus slightly punctate ; abdomen obsoletely punctulate. Euscelus carneolus, Erichson. The too short description of Erichson* agreeing with several species known to me, I must, in this perplexity, regard the various specimens of a species inhabiting Para, the Amazons and Cayenne, as representing that Erichsonian species, and I have to add that it varies as follows : — Var. a. (Maxim, color.) Sanguineo-rufus ; ore, antennis , oculis , linea medio capitis et thoracis , scutello medio , macula humerali apiceque elytrorum , punctis duobus pygidii apiceque femorum anguste nigris. * Very likely such are not the Erichsonian descriptions that my friend, Mr. A. White (Ann. Nat. Hist. ii. 356, Nov. 1858), would lead the actual and future authors to take model upou. Of course, the fame of Erichson, one of the most transcendant of our modern entomologists, has nothing to suffer from this my humble reply. Now, a word touching my micrometrical admeasurements: I cannot regard them with Mr. White (loc. cit.), as individual in their proportions; let these be taken upon the smallest, middling or largest specimens, they always have the same proportional results, and save us from eternal sentences like these: “ Elytra .... thorace dimidio, duplo, triplo . . . . latiora .... longiora . . . .” &c., and are far more exact. 216 INSECTA SAUNDERSIANA.

Ground-colour of a sanguineous hue, markings of the elytra more reddish or sanguineous. Rostrum more slender and elongate, according to the sex. Antennce black or blackish, more elongate and slender. Head not canaliculate. Thorax even, only showing a very slight appearance of a fovea on each side of the disk. Elytra more elongate, showing two costiform inter¬ stices; their ground black-colour has a bluish or violaceous hue, with the base evidently rufous; the suture to the apex rufescent ; the apex itself does not bear a real limited spot or macula, but is only, like the suture, indeterminately — indeed marginate — rufous. Besides, there is a lateral thin rufous line, beginning somewhat above the middle and finishing at the two-thirds. Rostrum punctate; head and thorax smooth ; pygidium and abdomen slightly punctulate ; pectus strongly punctate. Scutellum transverse, shortly subtriangular, with the apex rounded, shorter than in Eusc. amplectens. Elytra foveate-reticulate, with no interruption of the foveas on the rufous maculae and fascia, except the passage of the two costae. Genus TRACHELOLABUS, Jekel.

Body beneath and pygidium finely punctulate. Pilosity scarce on the upper part of the body and legs, denser underneath and on the posterior part of the elytra. Named after my obliging friend, Mr. Adam White, whose entomo¬ logical reputation is universal. Genus EUOPS, Sch . The scutellum in this genus is not subtriangular, as Schonherr states, but subquadrate, as indicated on Guerin’s plate (Icon. Begn. Anim. tab. 36, fig. 4 : Attelabus falcatus ), except that its size is ex¬ aggerated, for that organ is — relatively to the other groups of Attelabidce — rather small. The rostrum is abruptly deflexed, perpendicularly to the head, very much straightened at the base, triangularly ampliate to the apex, short. To this genus, formerly containing one single species, I propose to add some others extremely allied to the Schonherrian type, but, nevertheless, differing in a few instances ; and the only parts of that 220 1NSECTA SAUNDERSIANA. author’s description* that do not agree with all the species are the head, thorax and legs.

About the size of Euops Bowringii , Jekel : the rostrum is not so flat, the thorax is not obliquely, but transversely strigose; the elytra a little more conic, their shoulders more angulose, but also a little rounded, their punctures are smaller, more numerous, leaving the interstices broader, almost smooth ; they are transversely impressed behind the scu- tellum. This organ is of a rich metallic golden or emerald hue. The shoulders, pygidium, abdomen and legs are often more metallic than the other parts of the body, except the rostrum and scutellum, which are the most richly coloured. In some specimens a metallic macula is ob¬ servable on the vertex, close to the junction of the eyes. This admirable myrmidon must be a most dazzling and glittering little thing when alive. Genus RHYNCHITES, Ilerbst. This genus, as limited by Schonherr, has now become extremely numerous, and one may reasonably suppose the number of its species in the various collections as reaching over 150. The few new species I have here to register do not permit me to enter into a proposition of classification, that I would base upon the constitution of the head, ros¬ trum and eyes, shape of the scutellum, station of the pygidium, structure of the tarsi, claws, &c. 224 INSECTA SAUNDERSIANA.

Very much allied to Rhynch. betuleti, F., and, like it, is variable in size, hut is generally smaller. The rostrum is less elongate and arcuate, with the forehead and head not so strongly punctate ; the thorax is less convex, according to the sex, not really canaliculate; its punctures are much slighter; the scutellum has its posterior elevated part much more transverse, lineiform, not impressed ; the elytra, more deeply and widely impressed, behind the scutellum, have their punctures much smaller, in substriatiform rows, with the interstices wider. The former of those characters approach it nearer to Rhynch. Populi , L., but the size is larger, and, from the minuteness of the punctures of the elytra and the more widened interstices, these organs are much smoother; the impression of the forehead is much shallower and shorter, &c. Can much less be mistaken with Rhynch. fulgulus, Falderm. ( Rhynch . Faldermanni, Sch.) and Rhynch. rugosus, Gebler. Species also belonging to this highly distinct group, in which the males have the thorax spinose on each side, and which, in a further and COLEOPTERA. 225 natural distribution of this numerous and heterogeneous genus, will retain the appellation of Rhynchites , pr. diet., regardless of the variations of length of the rostrum, too secondary a character — com¬ pared with their numerous affinities— for their separation, as Schonherr artificially did it.

This species has a peculiar construction of the head and rostrum taken together, compared with the other species of Rhynchites. The head is rather elongate, subconically angustate from the base to the ros¬ trum, as in Rhynch. rugosus , and much like the other species of the group of Auratus (or spinose $) ; but the rostrum, instead of being narrower than the head, is almost even with the anterior part of that organ in width and thickness, seeming to be its mere continuation, and the eyes being very flat much increase that appearance. The rostrum is subangular at the sides, flat above, with a basal carina, more or less distinct. The forehead is impressed, and, like the rostrum and the 226 INSECTA SAUNDERSIANA. vertex, closely rugulose-punctate. The occiput is transversely thinly strigulose. The strigosities of the thorax are sinuately transverse on the disk, subcircular at the sides, concentrically disposed round, the ante-basal lateral impression ; the median canalicula is also impressed at the base. The elytra are somewhat narrowed posteriorly, their shoul¬ ders are roundly angulate, subcallose; they have a deep round depres¬ sion behind the scutellum ; their rows of punctures are placed two by two, from the alternate interstices being larger, elevate ; those punctures are divided in lacunae of unequal depth and length, by unequally distant elevate coarse rugosities crossing them. Pygidium, abdomen and legs closely — pectus and anterior coxae more strongly — strigose-punctate. Legs thick, short; tarsi incrassate, ultimate joint thickly clavate, claws relatively robust.

By the elongation of its rostrum this species should be ranged in Schonherr’s artificial Stirps I., but by all its other characters it COLEOPTERA. evidently belongs to a natural group, the type of which is our European species Rhynch. pubescens.* Rostrum more than half narrower than the forehead, and more than twice than the head itself, widely smooth along its middle. Head rather coarsely and remotely punctate on the fore¬ head and the anterior part of the vertex, smoother and very thinly transversely strigose on the occiput. Thorax truncate at the apex, with a shallow transverse impression behind it (obsolete in the male) ; punc¬ tures slight on the disk, more distant and stronger at the sides ; base slightly sinuate and rounded at the middle, thinly marginate. Scu- tellum small, apparently subquadrate, somewhat longer than broad, narrowed posteriorly, with the angles obtuse, canaliculate lengthwise, the canaliculation deeper at the apex, forming a kind of indentation. Elytra subtruncate and more than a half larger than the thorax at the base ; shoulders raised, roundly angular ; sides somewhat straightened behind the shoulders, then roundly ampliate behind the middle; widely rounded to the apex ; each elytron obtusely angulose at the apex of the suture; elongate, little convex above, deeply transversely impressed behind the scutellum ; 18 — 20 rows of slight punctures, of which the sutural and marginal are striate. Pilosity of the body almost every¬ where perpendicular to the derm, except at the apex of the elytra and body beneath, where it is rather inclined. Genus BELUS, Sch. This Australian genus, as understood by Schonherr, is now nu¬ merous in species, and its distinctive characters from Rhinotia , Kirby, * Body suboblong, slightly punctate, shining, bearing a long thin pubescent villosity.

As I intend to develope a project of classification of this group in ‘ Fauna Curculionidum Australis,’ the manuscript of which is going on, I will only here, before describing some new species in Mr. Saunders’ collection, observe that Mr. Perroud’s “Belus afiinis” (‘Melanges Entomolgiques,’ ii. p. 30, 1853) is a mere variety of Belus melanoce- phalus , Sch., long ago known in the collections of Europe, which variety is indicated by Germar in his ‘ Fauna Novae Adelaidae ’ (‘ Linnaea Entomologica,’ iii. 1848). Had Mr. Perroud known that old species (to which, if he knew it, he should have, at least, compared his pretended new species), or consulted Germar’s work, he would have avoided uselessly intricating the synonymy of this genus, and presenting as new observations so long ago made by that celebrated author in answer to Imhoff’s suggestions (Sing. Gen. Curculi.) on the sexual differences. Very happily for Mr. Perroud, his Belus bispinosus is distinct from Bel . hemislictus and Bel. scalaris of Germar. Belus amplicollis, Jelcel.

Thorax shaped as in Bel. semipunc¬ tatus , still less produced in the middle of the apex, a little broader, consequently still more conically ampliate near the base, which cha¬ racter, combined with the narrowness of the elytra, increases its pro¬ portional width. Elytra strongly depressed along the suture, but the elevated longitudinal limit of that depression is broadly convex, showing no appearance of the subcostiform line so well marked in Bel. semipunctatus , and still observable in Bel. hemistictus ; the base of the suture close to the scutellum is a little callose, but less than in Bel. bispinosus , also less elevated than the scutellum.

More allied to Bel. hemistictus, Germ, than to Bel. semipunctatus, F., by having the elytra still less impressed along the suture, with no appearance of an elevated line limiting that depression, and the thorax still narrower, less conical, and more slightly canaliculate along the middle ; the latero-dorsal lines almost parallel to the median, very little diverging to the base. Elytra narrower, more parallel, more regularly convex ; their sutural and dorsal lines are much narrower and composed of much smaller and more numerous maculae. Bel. bispinosus , Pen*., with the elytra also tuberculate at the suture close to the scutellum, is very distinct, by having these organs much broader and shorter, less parallel, not so strongly punctate-rugose, the thorax more finely and closely granulate, the canaliculation shallower and no latero-dorsal whitish line, the abdomen wanting of the median whitish line existing in our species, &c. Rostrum punctate-rugose at the base, glossy and finely punctulate to the apex. Forehead broader than the rostrum, subquadrate ; transverse impression behind the eyes narrow and shal¬ low. Thorax rather convex, subcylindrico-conic ; canalicula narrow and shallow, with the dorsal impression of each side (filled with a whitish line) almost parallel to it, as above recorded, and very shallow.

Femora of the other legs bearing a small oblique spine. Posterior femora reaching to the base of the third ring of the abdomen * * This last character is important, as an accessory to the distinction of the various types: in the filiform species, with the apex of the elytra singly rounded or obtusely acute and the femora always edentate, the posterior femora are hardly as long as the basal ring of the abdomen ( Bel. jiliformis , Germ., Bel.filum , Jekel, &c.), even in a new species of Richmond River extremely short, only reaching to the two-thirds of that ring ; in the appendiculate species (Sp. 1 — 3, Sch ., as types) and in those where the elytra are conjointly more or less acutely rounded at the apex (Bel. melanocephalus , Hope, Sch., Bel. sparsus , Germ., &c.) they generally extend to the base — very seldom above the middle — of the second ring; in Rhinotia they reach to the two-thirds of the second ring; in the groups where the elytra are less elongate and evidently wider posteriorly, and with Belus- like antennae (Bel. fumigatus , Germ., Bel. irroratus , Jekel, Rhin. pectoralis , Er., Rhin. Dermestiventris , Boisd., &c.), they are at least as long as the two basal rings; finally, in Pachyra , Hope, far more distant from Belus than Rhinotia , all the legs are equally long, their femora and tibiae long, slender, and the abdomen being very short relatively to the group, the posterior femora reach above the middle of its length. 334 INSECTA SAUNDERSIANA.

Add, “ M. Chevrolat verbally hints at this species being the Br. Mimosa of Fabr. Possibly that acute entomologist has been led to this supposition by comparing it to an Olivierian specimen in his collection. But the species of Olivier is very different from Fabricius’s in size and shape (at least; M. Chevrolat’s specimen and Olivier’s figure, for the description being chalked out of Fabricius — except the comparison of size to the Br. Pisi — is not to be accounted for), and still more so is Fabricius’ species from mine, as may be seen from his description and also from the more extended one of GyJlenhal in Sch. There remains only to settle my insular species with the continental one of Olivier (which is to be erased from Schonherr’s synonymy). Although I am acquainted with specimens from the South American Peninsula that I, until now, regarded as the Olivierian species (strictly speaking, an undescvibed one), it might be the two are similar. Nevertheless, I must warn M. Chevrolat of the great analogy of a number of closely allied species in the New World (V. Huj. Op. p. 17), which require a monographic revision. As regards the true Br. Mimosa , F., it is to Br. obtectus , Say (= Br. pallidipes , Sch.) that it should rather be compared, but I deem it distinct.

This last name should be preferable, as being not restrictive as the other, although the Amazons be the largest stream of the world. According to Dr. Gerstacker it is the true Sten. robuslus of Dejean Catal. ; a very possible thing (though the meaning of that name be less applicable to this species than to Sten. testudo , Jekel), for, although M. Dupont repeatedly boasted of his free and continual access to the late Dejean’s cabinet, and of his whole collection being 'perfectly named upon that entomologist’s types, every one knows how much he has induced Dr. Burmeister to misapplication of specific names ; therefore, I always very little trusted his determinations. Except the above-recorded, all the other species that have been described by various authors as belonging to that genus are of quite different generic forms, viz. : — 1st.

(Voy. la Bonite) are two very closely allied species, bearing a certain outward likeness to Stenocerus , but should be ranged close to Dendropemon , Sch., by their having the rostrum broad, as much as the head flat, sub- quadratiform, or rather somewhat shorter than long, hardly narrowed at the base, thin in depth, subcarinifonn and somewhat rounded at the sides to the apex, which is slightly emarginate (indeed very much alike to that of Platyrhinus lalirostris , F.), with the insertion of the antennae infra-lateral, at about the middle of its length, in a groove rather deep, elongate, infra-lateral, transversely directed underneath ; the eyes are supra-lateral, rather large and convex, obliquely and sub- angularly biting in the forehead at the base of the rostrum. The antennae are very short and thin, not reaching to the middle of the thorax in all the female specimens I have seen, and scarcely longer in the single male with entire antennae I could inspect; the first joint is oblong, clavate, not visible from above ; second subglobose ; the remainder of the funiculus very slender, successively shorter ; the club short, three-jointed ; first and second joints transversely triangular, much pointed inside; third rounded, flat. The remaining characters suf¬ ficiently developed in Guerin’s and Desmaret’s plates. ( Hylopemon , Jekel). ADDENDA ET CORRIGENDA. 239 2nd. Stenocerus collaris, Sch., is very distinct from the preceding species, and is a modification of the multifarious Asiatic genus Litocerus , in which the males have such long and thin antennse, and are — in proportion to their short-horned females — generally so rare, that for one of the females Schouherr has created his genus Acorynus. Now very numerous in species since the precious captures of Messrs. Bowring, Nietner and Wallace, it requires a complete revision, and any attempt to the raising up of isolated genera out of this group might prove unstable. 3rd. As regards the four species of Woodlark described by R. P. Montrouzier (Essai, &c., Lyons, 1857, pp. 40 and 41), one ( Macroph - thalmus ) very likely is a Litocerus-like female, and the three others may range close to Garnotii , &c. 4th. Stenocerus minutus and Sten. asperatus, Blch. Hist. Nat. de Chile (Conf. Huj. Op. Observ. p. 116), may provisionally be arranged with Tropicleres , to which they belong with more right than Asper , Sch., which, with Platyrhinus aculeatus, Fabr., Platyr. spiculosus, Sell., and many other undescribed American species, form a highly natural group. M. Chevrolat has already proposed a generic name for Anthr. aculeatus , Fabr., which may be regarded as the type of this new form, very distinct from Platyr. latirostris , viz., Slrabus , Chevr. in litt., a very acceptable name. 5th. Stenocerus tuberculosus and Sten. signatipes , Blch. loc. cit. (Conf. Huj. Op. pp. 116 and 117), exhibit a natural and special form, for which I propose the name of Hylotribus.

Curcul. x.) was different from Olivier’s, and identical with one, called by Klug “ Cas- taneusf in Mus. Berol. litt. I had very long ago identified Labram’s figures with specimens in my collection that I deemed really distinct from the castaneous varieties of “ Camelus , Oliv.” (which, by-the-bye, very much varies in the coloration, some specimens being pale yel¬ lowish rufescent, like some of our “ Coryli ’’) ; a separation, which, empowered by Erichson’s assertion, may as well be settled here with the following diagnostic : — Apoderus (Trachelophoeus) castaneus, Klug.

Elytra relatively narrower, smoother on their disk, with the rows of punctures more obsolete, almost null ; basal striae obsolete, especially across the basal tubercle, which is much higher, and posteriorly limited by a deeper semicircular depression. Sides of the pectus much more slightly punctulate. Finally, the antennae are shorter in both sexes ; and in the male their joints are very slightly ampliate inside the apex, when compared to Apod, camelus , $ .

(Madag.), undoubtedly is a short-necked female (like Apod, rufus , F.) of Trachelophorus , by the emarginate and nodose apex of its thorax, &c.

This species at least equals in size the largest Grecian specimens of Rhyn. Hungaricus ; is more convex and attenuate both sides, with the elytra more elongate and fornicate ; the rostrum somewhat longer and much more arcuate according to the sex, &c. Head elongate-sub¬ quadrate, somewhat broader at the base, transversely impressed behind the eyes, anteriorly rather strongly — posteriorly very slightly — punctate. Eyes small, globose, lateral, exserted, hardly biting into the forehead, which is almost as wide as the head itself. Thorax subconic, a little rounded at the sides above the base, flattened on the disk, attenuate and deflexed to the apex. Elytra conjointly subangularly emarginate at the base, obliquely rounded to the shoulders, where they are a half broader than the thorax, slightly ampliate to the middle ; apex of each rounded, almost entirely covering the pygidium, when the abdomen is not contracted ; striae of the disk shallow and narrow, the sutural and mar¬ ginal deeper, the two intra-marginal (lateral) ones evidently punctate. Pygidium and body beneath slightly punctulate. Anterior coxce rather elongate, conic. Claws short, incurved, free and subangulose at the base, divergent. Body covered with a bright silky fulvous pubescence, verj thin underneath, thicker above, especially on the thorax. ■ I N D E X TO PARTS I. & II.
