Doubt- less allied to the Hopniina on one side, and to the MELOLONTHIN”] on the other, the distinctive character of this Sub-Family is to be found in the mode of insertion of the two spurs of the hind tarsi, which are situated one on each side of the basal tarsal joint, sometimes near the outer angle of the dilated apical part, sometimes close to the tarsal joint, but never are the two found on one side of the tarsal joint as in the MmLoLoNTHIN# ; we have seen that in the SerRicin# there is only one spur, and as often none at all. Certain genera of the Ablaberzm are so closely allied to the Pachy- ~ podium, which I retain in the MrLonontuins, that but for that character they would have to be included among them, in spite of their having strongly dentate maxille. Another character of im- portance is the complete obliteration of the labrum, which part is always strongly developed in the MELOLONTHIN#. Trt SERICINI. Body elongate or very strongly ovate and convex; lateral margin of clypeus either nearly straight or very strongly constricted, anterior one always reflexed and either simple or tri-dentate ; eyes divided in front by the genal canthus, and having or not a posterior keel either connected with or disconnected from the genal canthus ; prothorax always sloping forward ; elytra elongated and then moderately con- vex, or strongly amphato-ovate and very convex, covering the propy- gidium ; pygidium wide, vertical in most cases, but sub-horizontal in Pleophylla ; anterior coxe almost sub-vertical, intermediate ones narrow and somewhat broadly separated, posterior always very broad, and wider along the sides than the metasternum ; femora and tibia very compressed, the hind tibie often broadly ampliated inwardly, and with two more or less obliterated, slanting, spinose, seldom entire ridges outwardly; hind spurs of the female not ampliated. Herr Brenske has divided this Tribe into Sericine and Trochaline, and has endeavoured to find for them characters which are not common to both. I regret to say that as far as the South African genera and species are concerned, I have been unable to find lines of demarcation between them. Brenske’s Sericin@ are doubtless, as a whole, of a more elongated form than his Trochaline,* which are as a rule, but not always, more spherical and shorter; but if we take * Cf. some species of Ablaberoides. 1904. ] Catalogue of the Coleoptera of South Africa. 3 such important characters as the shape of the clypeus and the pre- sence or absence of a posterior eye-keel, we find elongated species with a very strongly constricted clypeus and no posterior eye-keel (Arraphytarsa, Allokotarsa, &c.), and very short and convex species without constricted clypeus and with a posterior eye-keel (Dolero- serica). Some species of this genus have even the silky sheen of Serica, which is replaced by an opaline sheen in Trochalus. The number of antennal joints is either 9 or 10; that of the club is from 3 to 5 in the male (South African species) and of 3 in the female, except in Microtrachelus, where it is 4; this club is as long or longer than the pedicel in the male; the claws are cleft, the superior tooth being usually longer and more slender than the lower, which is often stouter in the male than in the female, often membranous or lobe-like, and in some genera, such as Hwuronycha, Allokotarsa, Allogistotarsa, these claws and also the tarsal joints are most abnormal. I have not met with this peculiarity in the short, spherical, or very convex species. Some of the genera are very closely allied, others offer good dis- tinctive characters in the male only, in which case the females are very much alike. An examination of the genital armature of the male is as necessary for the division of species as in the RuTELINE or MELOLONTHIN. The species known to me are generally met with in somewhat sandy spots, either at dusk or if the sky is overcast. Only a few species occur in the south-western part of the Cape Colony; they seem also to be rare in the eastern provinces of that part of South Africa, becoming more numerous, however, as Natal is reached, and are very abundant in the North-Eastern Transvaal, Rhodesia, and Ovampoland. Many of the species range from Natal to Mossamedes. Key to the Genera. A’. Hyes divided in front by the genal canthus, and having no posterior keel. 3 B?.

This species very closely resembles examples of Awtoserica ainectens, but it is easily distinguished owing to the tri-dentate tibize and other specific characters. DIAPHOROSERICA, n. gen. Plate XLVL., fig. 3. Very closely allied to Gryphonycha, the chief distinctive characters being the shape of the fore tarsi and claws of the male; the former are short, the second, third, and fourth joints are triangularly dilated, the fifth is much broader and longer, the claws are conspicuously diverging, each one is deeply cleft, the upper tooth of the left one being very slender, and the lower very broadly lobate, this lobe is conspicuously wider in the outer than in the inner claw; in the female the claws are deeply cleft, the lower tooth is, however, wider than the upper; antenne 9-jointed in both sexes, the 3-jointed club is nearly as long as the pedicel in the male. ‘The prothorax curves very strongly forwards, and the.mentum is not as densely hairy as in Gryphonycha. This genus differs from Neuroserica, Brensk., in both the anterior claws of the male being toothed and not widened, lobe-like, and in the club not being strongly elongated. DIAPHOROSERICA MASHONA, N. spec. Rufescent, with a fleshy tinge and a more or less strong opaline sheen; antenne testaceous; clypeus with a plain frontal suture, arcuately emarginate in front but with the margin reflexed and slightly aculeate in the centre, the outer angles are distinct, but not prominent, the surface is deeply punctured, the head less so; prothorax slightly narrowed laterally in front, sinuate behind and also along the base, sloping forwards, vaguely punctulate only along the base and sides; scutellum long, aciculate; elytra elongated, plainly striato-punctate with the intervals sub-tectiform, the punc- tures of the striz impinge on each side of the sub-tectiform intervals; anterior tibize bi-dentate.

This margin is either normal, i.c., it is continued as the edge of the outer anterior angles (T. ferrugineus) or disappears before reaching the very strongly reflexed anterior part (Z'’. modestus), or again is produced diagonally across the anterior part and reaches there the anterior margin either in the centre (Z’. damarus) or at a short distance from it (Z’. badius) ; whenever this upper lateral margin is diagonal, the lower margin of the clypeus becomes more visible, the anterior margin is always strongly reflexed, and either sharply or bluntly tri-dentate, or not even aculeate in the centre, and the median tooth is never prolonged — into a longitudinal keel dividing the not very hollowed anterior part into two as in the genus Ablaberoides, but many species have a longitudinal median keel, sometimes even very conspicuous, which, however, does not reach either the base of the median anterior tooth, or the sharp transverse carina which divides the clypeus from the. — frontal part; the latter bears in some species (7. chloris, T. vagus, &c.) a transverse groove sometimes more shallow in the female than in the male, equi-distant from the frontal keel and the base and running parallel to it; antenne 11-jointed, club 3-jointed, as long as or longer in the male than the pedicel; prothorax short, convex, ampliated laterally from the anterior to the basal angle; scutellum long, sharply acuminate; elytra sub-spherical, ovate or elongato- ovate, mostly striate in the dorsal part only; anterior tibize bi- or tri-dentate outwardly, the trochanters of the anterior pair broadly triangularly dilated, hind femora broad, posterior tibize broadly dilated, shorter than the femur, having one distinct and another partly obliterated transverse chevron-like ridges, inner margin stiffly bristly ; anterior tarsi somewhat short, posterior ones longer, hind spurs of the latter longer than the basal joint; claws symmetrically cleft underneath ; pygidium slightly convex, hind coxee very slanting and narrow at the base. 42 Transactions South African Philosophical Society. [vou. XIIl. The type of the genus, as restricted by Brenske, is 7. rotwndatus, Casteln., from Senegambia. Until all the numerous species included hitherto into this genus have been revised, it is impossible to say which belong to Trochalus, Ablaberoides, or other kindred genera,” or to obtain an idea of their distribution in Africa, to which continent they are restricted. In South Africa they are widely distributed, several of the species described by Fahreeus as from Natal, or what is now the Transvaal, have been recorded by me from Damaraland and from Ovampoland in the neighbourhood of the Cunene River, but only one species is recorded from the south- western part of the Cape Colony, 7. @rugineus, and it ranges from ? Cape Town and Mossel Bay to Natal and the Transvaal. Burmeister described six species from South Africa. Although I have not been able to compare, or to have my examples compared with the types, I have identified with tolerable certainty three of these species described again under another name by Fahreus, and which have therefore priority ; another species is probably the very type of the genus Ablaberoides of Blanchard; the fifth, having a 4-jointed antennal club, may prove to belong to the genus Micro- trochalus, in which case it would be a female and not a male as suggested by Burmeister; I have not been able to identify the sixth, which I suspect, however, to be identical with another species.

Trochaloserica, Brensk., loc. cit., p. 82. Mentum nearly similar to that of Trochalus, but usually wider at the base ; palpi identical, maxillee with three superposed teeth, the two lower ones bifid ; clypeus always more or less narrowly constricted laterally in front, as well as sinuate between the genal projection and the constricted part, the anterior margin is strongly reflexed, and in the majority of species its median part is very strongly dentate, in which case the tooth is continued as a longitudinal keel dividing the strongly depressed anterior part into two, or it is merely angular, in that case the anterior part is not hollowed, there is a clypeal keel which is seldom indistinct, and a frontal grooved suture, which, however, turns into a short keel in a few species; the eyes are almost completely closed (Ablaberoides) or the hind keel does not coalesce with the genal canthus, but is always developed (Zrochalo- serica) ; the antenne are 10-jointed with the club tri-jointed and very long in the male (Ablaberoides), or 9-jointed (Spherotrachelus) ; prothorax short, strongly transverse, fringed with long sete ; scu- tellum large ; elytra short, sub-parallel or ampliato-ovate, in which case they are more convex than when sub-parallel, punctate, striate or non-striate with the exception of the juxta-sutural stria which is always plainly visible; pygidium moderately convex; pro- and meso-sternum hairy; anterior tibiz bi- or tri-dentate, legs of T'ro- chalus but with the anterior trochanters not so strongly dilated. The characters assigned by Brenske to his genus Spherotrochalus agree very well with those of Ablaberoides, of which I have seen the type, except that the antenne are 10- instead of 9-jointed, and T’ro- chaloserica, also one of Brenske’s genera would seem to differ mainly in both eye-keels not being in contact. After careful examination I came to the conclusion that completely or incompletely closed eye- keels did not coincide with 10- or 9-jointed antennz, and that these characters can be made use of merely to group the species, not to divide them into genera. 1904. | Catalogue of the Coleoptera of South Africa. og The characters distinguishing this genus from Tvrochalus are the presence of a strong, hind ocular keel which either unites in a straight line with the genal canthus or is not quite connected with it, in which case it is slightly higher than the genal keel, and the presence of a transverse clypeal keel edging the usually deeply depressed anterior part of the clypeus the lateral margins of which are always continued as far as the sharp apical angle instead of being produced into a more or less sinuate keel above the margin of the anterior part. The uniformity in facies and the enormous variation in colour makes the study of the species a most difficult one, but the shape of the genital armature helps greatly in the identification ; these arma- tures are, however, so very complicated that it is difficult to give a good description of them, and I greatly regret that I could not have them figured; the presence or absence of an additional antennal joint helps also in grouping species which but for that character would be hardly distinguishable.

Black, shining, with the elytra either brown or chestnut-brown and a conspicuous iridescent sheen all over, more noticeable, however, on the elytra on account of their great convexity; in general appearance it differs from A. ditessumus in not being so square owing to the elytra being much more rounded laterally behind and also more convex on the dorsal part; the pedicel of the antennz is rufescent, and the club, which in the male is slightly longer than 1904. | Catalogue of the Coleoptera of South Africa. 63 the whole pedicel, is black; the clypeus is tri-dentate in front, but the angle of the lateral sinuation is rounded, the clypeal keel reaches the sides; the shape of the prothorax is the same as in A. ditis- sumus, but the punctuation of that part and also of the head is neither so deep nor so rugose; the sharply ogival scutellum is also sparingly punctured ; the elytra have only three, or at most four, plain striz, and the punctuation of the intervals, as well as of the sides, is deep, but not as much as in A, ditissemus, and the under side is alike, but the anterior tibiz are bi- instead of tri-dentate outwardly ; in the male the tubular part of the armature is notched in the centre and on each side, and the two forcipate processes are symmetrical, long, slender, and curve upwards at the tip.

The description of A. crassus applies in its entirety to the present species, which, is, however, constantly smaller, the colouration of the elytra seems to be also constant, they are dark bronze with a rufo-testaceous broad band extending over half the width of the elytra, and beginning at about the third dorsal stria; the anterior tibia are also tri-dentate outwardly. In spite of its great likeness to A. crassus, the difference in the shape of the genital armature is very great; the forcipate processes are symmetrical, very short, and bent downwards.

If the genital armatures, which are on the same plan, of the two species are compared, it is seen that the tubular part is much more deeply notched and twists inwardly on the left side in A. lactulus, the right process is sub-horizontal and does not therefore act as an operculum, the inner forcipate process is very short, and the apical part of the tubular part is flattened into two small processes.

Ovate, reddish-bronze, with the elytra often greener, and with an opaline sheen, antenne and palpi flavescent or rufescent, the club slightly longer than the pedicel in the male; the sharply tri-dentate clypeus is not as sinuate laterally as in 7’. emeritus, and the upper angle of the lateral constriction is very sharp; instead of a frontal suture there is a plainly raised line; the prothorax is of the same shape as that of 7. emeritus, but the punctures, although equally fine, are not set quite so close to each other, and the intervals in the median dorsal part are not sub-strigillate; the elytra are more elongato-ovate and appear therefore less convex in proportion, in nearly all my examples the four dorsal striz are distinct, and as often as not there are plain traces of a fifth and even a sixth; interior tibiz bi-dentate outwardly; this species is easily recognised from its congeners by the presence of a raised line instead of a grooved suture at the junction of the clypeus with the frontal part, but the shape of the genital armature distinguishes it also readily, the two claspers being strongly twisted, spatulate at the tip with the upper one nearly erect, and the other curving upwards underneath. Length 63-64 mm. ; width 32-44 mm. Fahreeus, in his description of the species, says that the anterior tibie are tri-dentate, and that with the exception of the sutural stria which is impressed behind, the strize are hardly visibly striate.

Testaceous-red, with a bright sub-metallic not iridescent sheen; antenne flavescent; as spherical as A. emeritus; the clypeus has sharp outer angles which are not, however, plainly reflexed, and the median part is not dentate, the constricted part is narrow, and the sides above it strongly sinuate, the frontal suture is replaced by a fine raised line, and in the only example of this species which I have seen there is in addition to the faint frontal suture a slightly im- pressed, transverse line equi-distant from the frontal suture and from the base; the prothorax is closely and the elytra sparingly and weakly punctulate, the dorsal strize, with the exception of the juxta-sutural one which is visible in the posterior part, are almost obliterated. The raised line of the frontal part and the non-tri-dentate clypeus will help in distinguishing this species from A. emeritus, and the non-tri-dentate clypeus from T’. fahrez, which has also a raised frontal line, but which is not so spherical.

The variable number of antennal club joints has led to a great generic division where specific distinctions, would, in my opinion, have achieved the same result. This great variation in the number of joints of the antennal club is a curious feature of the insects included in this Tribe; it varies in the male from 7 to 4, and from 6 to 8 in the female; the claws are slender and not deeply cleft underneath, but the basal part is often dilated and membranaceous. On the whole the Tribe is very homogeneous, but certain genera, such as Tulbaghia and Idecamenta, are closely allied to the Pachy- podous Melolonthine, and have probably the same habits. The females of Ablabera, Camenta, &c., are, however, met with as commonly as the males. The species of Ablaberint seem to be more restricted to the South African Fauna than the Sericint ; a few of them have been met with as far as Masailand, but I believe that none are found in Senegambia. The range of the species in South Africa is very limited, differing in that respect from the Serecini, but the habits of the two seem to be the same. 1904.] Catalogue of the Coleoptera of South Africa.

The species which I have been able to observe fly very low in the daytime, and are met with from August to April in the Western Pro- vinces of the Cape Colony. The genus might be divided into two sections (Parablabera, Ablabera), owing to the number of joints forming the antennal club, but it is sometimes difficult to decide if the last joint of the pedicel is a part of the club or not, owing to its being very often briefly laminate. This division is also very artificial, because A. gratula, for instance, with a 7-jointed club in the male has the same shape and colouring as the species belonging to the group in which the male has a 6-jointed antennal club. The first section is mostly restricted to the Cape Colony, but it has one representative in the Transvaal. One species of the genus is recorded from German East Africa. The character distinguishing this genus from Microcamenta, the claws of which are alike, is the absence of a median transverse ridge or clypeal suture in addition to the frontal one, and from Camenta, the shape of the claws which are not lobate or swollen underneath at the base.

As stated in the diagnosis of this genus, the species can be divided into two groups according to the shape of the clypeus which is incised laterally or not, but this character has not a great generic im- portance, occurring as it does in species closely allied in general form as well as in others the general facies or even size of which differ somewhat considerably. An attempt has been made by Herr Brenske to split the genus mainly according to the number of joints composing the club of the male, and occasionally also of the female. This character is so much more fictitious that the joints of the pedicel abutting on to the club are always compressed, aculeate and laminate with a tendency to form an additional joint, even in several cases the inner joint of the club is only one-quarter of the length of the one following, and this same joint varies in length according to species; this goes far to prove that a specific character is thus made to serve as a generic one. I attach much more importance to the disappearance of an antennal joint than to the increase or decrease in length of one of the club joints; but even the distinctive value of the presence or absence of one or more joints in the antenne is somewhat illusory when we find that in genera very closely allied to Camenta the male has a 10-jointed antenna and the female a 9-jointed one, and again in the male of a species belonging to a genus or sub-genus which but for this character could not be separated at all from Camenta, the antenne are 9-jointed. 92: Travsactions South African Philosophical Soctety.

Body without scales or squamose hairs,* in most cases densely hairy on the pectus and along the base of the prothorax; ligula fused with the mentum, both either broad or reduced to a mere stem-like process, maxille edentate, but with both lobes occasionally sharp, labial palpi inserted either laterally or on the outer face of the mentum, basal joint occasionally obliterated; antennae 8—10-jointed, number of club joints variable in both sexes, clypeus either slightly blunt in front with the angles rounded, parabolic or semicircular with the apical margin always strongly reflexed, vertical or slanting backwards in front; eyes always large, briefly divided by a short canthus, frontal part keeled laterally or not and having often a trans- verse prominence or keel along the vertex ; prothorax short, sloping in front; scutellum cordate ; elytra depressed on the dorsal part, seldom plainly costulate or striate and with a humeral callus, but no apical one; abdomen either moderately convex or strongly com- pressed laterally in the male; the segments free or deeply imbricated, the ultimate one provided with a broadly extensible membranaceous hinge; anterior coxe sub-vertical for at least one-third of their length, and conical at apex; hind femora swollen; hind tibiz broadly dilated ; episterna broad and separated by a sinuose line, often carinated in the upper part, from the epimera which are nearly equally broad. The non-soldered segments of the abdomen and the edentate or nearly edentate maxille are really the only characters distinguishing this Tribe from the Melolonthim. Many of the characters enume- rated above need, however, some explanation, in so far that the South African species and genera are concerned. The shape of the upper lobe (galea) of the maxille varies considerably: it is either hollow, compressed, arcuate or laminate, denticulate or serrulate, * Onocheta is an exception, it has squamose hairs on the intervals of the elytra. | li Hi mi ——————— SS 116 Transactions South African Philosophical Socrety. [vou. Xm. and even completely obliterated, it never has any teeth inwardly ; the inner lobe is always visible, which is not the case in the Serzcine or Melolonthim, and is either sharp or equal in length to the upper lobe, in which case it gives to the maxilla a tri-cornered appearance, and even when the galea is quite obliterated it is represented by a few more or less rigid seta. It is plain from the structure of the maxille, and also of the mandibles, that the males do not take much solid food, or in many cases any at all, unless they have suctorial habits. The maxillary palpi are either inserted laterally or on the outer part of the mentum which is never plainly separated from the labial or ligular part. It is, however, somewhat difficult to decide when the insertion is lateral or not, because the condyle, which is often very deep and wide, impinges often more on the edge of the outer face than on the lateral side, this insertion may then be said to be juxta-lateral, but it happens also that the basal labial joints are inserted on the narrowed outer face in such a way that they are either very close to each other or quite contiguous, this character coincides with an extremely narrowed mentum. The number of joints of these labial palpi is normally three, but in some cases (Clitopa, Pseustophylla) the basal one has disappeared or is so deeply buried in the condyle as to be invisible, or the second and third are fused together (Apevopsis), the condyle is very oblique, very broad, and with such a carinate outer edge as to often form a sharp angle at the junction of the mentum with the lhgular part; the labial palpi are long, especially the apical one ; the clypeus is strongly vertical and broad in the anterior part, the anterior margin is strongly reflexed, and the upper anterior part often concave or depressed ; the frontal part is either carinate laterally above the eyes, in which case this pecu- liarity coincides with the presence of a transverse keel or prominence on the vertex (Cyclomera, Paraclitopa, Periclitopa, Pseustophylla) or not; the labrum is usually very distinct, but is obliterated in two genera (Achelyna, Pleistophylla) ; the eyes are always large and very briefly divided in front by a short canthus, they show always less on the upper than on the under side, where they are sometimes so enormously enlarged that the mentum has been correspondingly narrowed (T'richinopus, Pseudachloa, &c.); the antenne are 8-10- jointed, in the male the joints of the club vary in number from 8 to 3, and in the females of the South African species known to me from 5 to 8, this club is always greatly developed in the male, being some- times more than three times the length of the pedicel the two last joints of which are generally compressed and acuminate or laminate, and the basal joint is in the shape of an elongated club, only in one 1904. ] Catalogue of the Coleoptera of South Africa. 117 genus is the third joint plainly longer than the fourth (Clitopa), the club itself is either laminate, parallel, or spatuliform in the male, and ovate or ovato-ovate in the female; pygidium either vertical, sloping slightly backwards, or strongly drawn forwards ; abdominal segments plainly not soldered together but in many species provided between the two ultimate segments with a distensible membrane, which would seem to imply that the other segments are only partially free ;* anterior tibia bi- or tri-dentate, and with or without an inner spur, hind ones triangularly dilated towards the apex, spurs long, sub-contiguous, either sharp in the male or compressed and broadly dilated in the female, tarsi moderately long, or long, occasionally ciliate. With the exception of Clitopa precalva, little is known of the habits of the South African species. In the case of the former, how- ever, they are those of certain Algerian species of Rhizotrogus, the females are wingless, the eyes considerably reduced, and they do not seem to leave the ground; the eyes are, however, not much inferior in size in the two females of Agostetha and Macrophylla which I have seen, nor are they without wings. I suspect that several species will, however, prove to have apterous females. This Tribe is represented in South Africa by forty-eight species representing twenty-four genera, which, with the exception of one (Clitopa), seems restricted to the South African area, but five kindred genera, including each one species, are recorded from Sansibar and British and German East Africa. I expect, however, that this number will be considerably increased. On the whole, the South African genera and species are fairly homogeneous, and merge insensibly into one another, in spite of the melolonthidous appear- ance of Aigostetha, Macrophylla, or Onocheta. Lacordaire founded for the reception of these genera a Sub-Tribe of Melolonthine, the Macrophyliides, thus separating them from his Sub-Tribe Pachy- podides, and associating them with Sparrmanna and Sebaris. He is evidently in error, because not only the species of these two genera have maxille very strongly dentate inwardly; but the abdominal segments are very plainly fused together, and not ‘‘non, soudés ensemble,’ as Lacordaire states, also because the maxille of Aigostetha, Macrophylla, &c., cannot be said to have a dentate external lobe. Sparrmanna and Sebaris belong to the Melolonthina, but form a distinct link with the South African Pachypodini, of which they have the livery, just as 4/gostetha, which, except for its livery, so closely resemble in general facies and shape of clypeus * This membrane is also found in the genus Schizonycha and allied forms of Melolonthine, in which the segments are quite fused. 118 Transactions South African Philosophical Society.

Owing to the obliteration of the labrum the genera Achelyna and Pleistophylla, are also connected with the Sericine, but are differentiated by the mode of insertion of the spurs of the hind tibize as well as by their Pachypodinous appearance.

This genus differs from Macrophylla merely in the number of the antennal joints forming the club, these being three instead of five, the club is in some species even longer and more curved than in Macrophylia, and the seventh joint is occasionally also laminate and long; the shape of the clypeus varies also in the species, some having an inner spur on the anterior tibia, others none; the facies also is not uniform, being sub-cylindrical in some and plainly depressed in others; these differences, however, and also some other minor ones cannot be regarded as generic.

Brenske’s genus Dvzaclaspus founded on a species, D. delagoensis, is in all respects identical with Cyclomera. I know only the males of the three species I include in this genus, but Klug has given the figure and description of what he believed to be the female of Cyclomera dispar. Like the females of the two species of Macrophylla known to me, it is more heavily built than the male, more convex, the femora are very short and thickened} the hind ones almost resembling a disk, the tibize are short, the hind ones even shorter than the femora, tolerably three-cornered, and nearly as broad as long at the apex, with the spurs strong, short, and bluntly pointed; the tarsal joints are very short, and the claw very small. The species included in this genus are densely but somewhat briefly hairy on the prothorax and scutellum, and have a very long pubescence on the pectus; the elytra are shagreened and clad with a very short, appressed pubescence.
