By J. M. Brack. [Read April 10, 1913.] PLATE: I. Pectinella, gen. novum. Flores unisexuales, solitarii, basi vaginante foliorum inclusi; flos masculus nudus; anthere 2, quadriloculares, leviter cohzrentes, ped- unculo communi inserte, polline filamentoso; flos femineus sxpius bracteolis membranaceis plus minus connatis absconditus; carpella gemina, non _pedi- cellata sed pedunculo communi inserta, in stylum attenuata, stigmatibus 3 capillaribus; carpellum fructi- ferum subdrupaceum, mesocarpio carnoso, endocarpio corneo, in lobos 4 truncatos rigidos productum, itaque perianthium quadrilobatum simulans; embryo mox intra fructum apice ramuli persistentem germinans et per basin fissam styli procedens, demumque pericarpio emacerato quadripartito et pectiniformi cinctus ad fundum maris descendens et ibi radicans. Folia alterno-disticha, caules nonnulli repentes, ad nodos radicantes. Herbze sub- marine. This genus differs from any other in Potamogetonacee in the structure of the anthers, the hard 4-lobed framework of the fruiting carpel, and the peculiar mode of reproduction. Pectinella antarctica. Herba submersa, floribus dloicis, foliis apice lunatis, anthera a basi valvis 3 dehiscente, connectivo in acumina gemina producto, uno carpello sepe abortivo. This plant has already received nine different names : — Amphibolis zosterifolia, Agardh; Caulinia antarctica, R. Br. ; Cymodocea antarctica, Endl.; Cymodocea zosterifolia, F. v. M.; Graumuellera antarctica, Reichb.; Kernera antarctica, Schult.; Posidoma antarctica, Spreng.; Ruppia antarctica, Labill.; Thalassia antarctica, F. v. M. This multiplicity of names is chiefly due to the flowers remaining unknown for so long. It grows in salt water along the coasts of Victoria, South Australia, and Western Australia, and was first recorded by Labillardiére, the botanist of the expedition sent by Louis B 2 XVI. in 1791 to search for La Pérouse. His specimens, obtained near Cape Leeuwin, W.A., were in leaf only, and judging by analogy, he named and figured them as /uppia antarctica in his Nove Hollandie Plantarum Specimen, ii., p. 116, tab. 264, published in 1806. Charles Gaudichaud, botanist to Freycinet’s voyage of discovery, 1817-1820, collected the same plant at Shark Bay, W.A., and this time male flowers were found and described (Voyage autour du Monde: Botanique, p. 430, tab. 40, fig. 2). No further investigations seem to have been made with regard to this plant for many years, until Mr. J. G. O. Tepper, a Fellow of this Society, acting on the suggestion of Baron von Mueller, collected specimens at Ardrossan, and gave the result of his researches in two papers read before the Royal Society in 1880, the first being entitled “Some Observations on the Propagation of Cymodocea antarctica, Endl.” (Trans. Roy. Soc., S.A., iv., 1-4 and 47-49, plates 1 and 5). Mr. Tepper does not appear to have found the male or young female flowers, but the conclusion at which he arrived is, I think, justified by the facts. It was “that the plant does not at all develop a fruit proper, nor does the seed ever become dissociated from _ its plant, but that the fertilized ovum at once germinates and develops into a new plant, which at maturity is detached, and begins an independent cycle of existence.” The object of the present paper is to supplement the observations made by Mr. Tepper over thirty years ago. Mr. Tepper forwarded his paper and specimens to Pro- fessor P. Ascherson, of Berlin, who replied that in the “fruits” he could find “nothing of the organs of a pistillate blossom, seeds,” etc., and he considered the process to be purely one of vegetative reproduction (Trans. Roy. Soc., 8.A., v., 37). In the same letter Ascherson states that he had seen one specimen of the female flower submitted by Baron von Mueller. This must have been a very young flower, and the fact that the 4-lobed comb is the final stage of the female flower was over- looked. The theory of vegetative reproduction seems to have been accepted by botanists ever since 1880. P. Ascherson, speaking of Cymodocea antarctica in Engler and Prantl’s Natirliche Pflanzenfamilien, 11., 1, 195-6 (1889), summarizes the supposed process as follows:—‘‘An ordinary foliage leaf {at the summit of a leafy shoot] is succeeded by a scale-leaf or ‘comb-leaf,’ whose median plane is transverse to that of the foliage-leaf. To this scale-leaf are added other leaves in nor- mal distichous succession. By destruction of its softer parts the strongly developed mechanical tissue of the new comblike, incised scale-leaf is set free; beneath its insertion the end 3 of the shoot divides, anchors itself firmly by means of the comb- leaf, takes root and grows into a new plant.”’ A. Kerner, in his Natural History of Plants, 11., 807 (English ed. 1895) says: -—‘“Towards the close of the winter the end of the stem above the leaves is seen to become peculiarly modified. Its internodes become much contracted, and at the lowest node is developed a scale-leaf with 4 lobes, which sur- rounds the leaves developed from the upper nodes, like a cup. Buds arise in the axils of one or two of these leaves, while the leaves themselves die and decay. The parenchyma of the 4-lobed, cup-shaped scale-leaf also decays, and only its stiff veins remain, so that instead of the cup there are now only comb-like scales. After this alteration has taken place, the tissue of the stem below the pectinate scales breaks across, and the whole shoot-apex, separated from the lower part of the stem, which has long been in a leafless condition, is carried away by the currents of the water.” The views expressed by these eminent authorities will require considerable modification when it is realized that the new plant springs, not from any reduced leaf or scale-leaf, but from the female flower itself. At the beginning of this year Mr. H. H. D. Griffith called my attention to this plant, which grows beyond low-water mark at Henley Beach, and is often cast up on the shore. He suc- ceeded in finding several male flowers and also the female flower in such various stages of growth as enabled us to trace its gradual development up to the “comb.” The flowers are dicecious, and both male and female grow at the end of rather short branches, sheltered by the broad sheaths of the two upper- most leaves. The males have no other protection, and consist of two 4-celled anthers on a common peduncle. Each anther opens from below in 3 valves and emits the threadlike pollen- cells, which float about in the water until they find the slender stigmas of the female flower. This consists of twin carpels on a common peduncle, one carpel often abortive. Like the males, they are at first sheltered in the leaf-sheath, but they have also in most cases a row of membranous bracteoles, often united in the shape of a cup which completely encloses the flower. As soon as fertilization has taken place the long stigmas break off, and without any period of rest the embryo begins to grow and the fruit to form. Four small truncate lobes, which have appeared about the middle of the carpel, increase rapidly in size and spread outwards, assuming the appearance of a perianth. Fleshy on the outside, they soon develop a horny inner framework, whose short, tubular part forms the inner- most layer of the pericarp and protects the growing embryo. Nourished by the albumen stored about its base, the embryo B2 = soon reaches the summit of the fruit. In the meantime the base of the style has split into two parts, and through the aperture the plumule emerges into the water. The soft tissue of the pericarp decays, probably by a sort of maceration in the sea water, and there remains only a 4-lobed comb, each lobe cut into 10-20 subulate teeth, and the hardened tube gripping the base of the embryonic plant. The comb breaks away from the end of the branch and sinks to the bottom, where the teeth of the lobes catch in the fibres of Posidonia australis, or in other material lying on the sea-floor, and so anchor the new plant while it roots and grows. There are still several points which require clearing up, such as the history of the ovule in the very young carpel, which has not yet been seen. At the fall of the stigmas, the embryo already occupies nearly the whole of the ovary, and the integuments of the ovule seem to have been absorbed, per- haps in the store of albumen. Or it may be that the pollen finds great difficulty in reaching the stigmas, and that in order to ensure reproduction of the species, the ovary develops a bud in place of an ovule, as is said to occur sometimes in Crinwm and Amaryllis. Against this hypothesis are the facts that the growth in the ovary resembles an embryo, that the anthers are fertile, and that no fruits of a different and more normal character have been found. Nor do we yet know what period elapses between the emergence of the embryo from the fruit and the fall of the comb, but probably flowering takes place from September to January, and the young plants are firmly rooted before the beginning of winter. It is also probable that there are two forms of P. antarctica. One, very numerous at Henley Beach, and which may be considered the type, has shorter leaves (sheath, 8-10 mm. long; blade, 12-35 mm. long), and a much rarer variety, found at the same place, has longer leaves (sheath, 15-20 mm. ; blade, 40-70 mm.). No male flowers or young females of the type were found, January being apparently too late for them, but both were gathered on the long-leaved variety, which flowers later, and the development of the carpel, apart from the fact that the membranous bracts are fewer, although rarely quite obsolete, is exactly the same as in the short-leaved form. There are certain analogies between the fruiting of Pectinella and that of two genera of a distant family, the Rhizophoracee. In Rhizophora (the tropical mangrove) there is likewise no seed in the ordinary sense of the term, as the embryo germinates in the fruit while the latter is still growing on the tree, and without a period of rest; in Brugwiera the similarity is increased by the fruit itself falling to the ground along with the growing embryo.

By H. J. Carter, B.A., F.E.S., Corresponding Member. [Read April 10, 1913.] In 1892-3 Mr. Blackburn published his revision of this group, and rendered a notable service to our knowledge of this numerous and little-known sub-family, by giving an elaborate tabulation thereof. Since that date Mr. Blackburn has himself described several species, Herr Gebien has described seven, and the author now proposes to add twenty- two more. Further, a good deal of information has been available to the author, especially in access to the Macleay types and a visit to the Hope Museum at Oxford in 1907, so that it is now possible to correct’ some of the unavoidable inaccuracies made in the revision referred to above, while it is hoped that future workers will find some assistance in the present notes and tables towards a more complete accuracy. Mr. Blackburn’s table is sometimes obscured by the use of characters inconsistent with his descriptions, ¢.g., C. acon- spicuus is placed amongst species “with ocular sulcus,” whereas in the description he says “sulcis ocularibus nullis.”” Again with C. longiusculus his table says “interstices convex and impunctulate,” whereas in the description he says “‘inter- stitiis rotundo-elevatis sparsim subtilissime elevatis” (sic); the last word being presumably a misprint for “punctatis.”’ In the tabulation given below, the author has differed materially from Mr. Blackburn’s system—(1) In attempting what is hoped will prove a simpler scheme for identification of species: (2) in paying less regard to the “ocular sulcus” as a character that is clearly defined in but few species: (3) in paying more consideration to colour—especially of the pro- notum; with one or two specified exceptions in the species having a black pronotum that character is constant, and therefore forms a convenient character for division in a large genus; where, however, the “ocular sulcus” is well defined it has been also utilized: (4) the ratio of length to breadth is a generally constant character, and serves admirably for tabulation ; some hundreds of measurements have been made to prove this, and the author would suggest the term “rational index” to denote this ratio. Mr. Blackburn’s corroboration of Blessig’s separation of Amarygmus from Chalcopterus is amply confirmed by the 7 author’s dissection of a large number of specimens, which show that in all cases examined the species recognized by Blackburn as Amarygmus have bifid mandibles, while in Chalcopterus the apex of the mandibles is evenly truncate. The statement that ‘‘there are few specimens in which the mandibles are so hidden that there is the least difficulty in discerning their form” is only true in the larger species, or in the smaller ones if the mandibles happen to be widely extended. Otherwise it is generally necessary to dissect the head, or at least to extend the mandibles, after relaxing the specimen. The author’s determination of species has been greatly facilitated by the valuable help given by the late Rev. Canon Blackburn in the loan and gift of co-types, the determination of others, as also by that learned entomologist’s valuable memoirs on the subject. An immense number of specimens have been examined, including the valuable col- lections in the following museums :—Macleay and Australian Museums, Sydney; National Museum, Melbourne; the South Australian Museum, Adelaide; Queensland Museum, Bris- bane; the Musée d’ Histoire Naturelle, Brussels; the four first of which contain many types or co-types named by Blackburn himself. The author would take this opportunity to thank for the courtesy the late Mr. G. Masters, Mr. Rain- Dewees, Mr: J. A: Kershaw, Mr. A. M. Lea, F.E.S., Dr. Hamlyn-Harris, D.Sc., for their help, and especially Mr. Lea and Mr. C. French, the former for the loan of his fine collection and the gift of many duplicates and the latter for the gift of many new and rare species, as also Mr. H. Griffith, of Adelaide, Mr. A. Giles, F.E.S., of Perth, and Dr. E. W. Ferguson, of Sydney, for much assistance. Lastly, I am indebted to the courtesy of Mr. C. O. Waterhouse for com- paring specimens sent to the British Museum with types and for his valuable notes thereon. Since writing the above, I have had the very valuable co-operation of Mr. K. G. Blair, of the British Museum, who has been able to examine and compare the respective types of Fabricius, Hope, Pascoe, and Blackburn, and who has been good enough to send me copious notes on the species examined. Further, and more valuable still, the authorities of the British Museum have permitted Mr. Blair to send me a large number of specimens, including many that have been compared with these types, so that it is now possible to clear almost the whole group from the clouds of uncertainty. My very cordial thanks are due for the courtesy of the British Museum authorities, and especially to Mr. Blair for this timely assistance and for his permission to use his notes. 8 CHALCOPTERUS, NoTES ON DESCRIBED SPECIES OF. C. puncticollis, Hope... Specimens from South Perth were compared with type by Commander J. J. Walker, R.N., M.A., who writes that they are identical. Below is given a description taken from a specimen compared with the type. C. opacicollis, Macl. In the Australian Museum are the Gayndah types, though, as was the unfortunate custom with Sir W. Macleay, they are not specially marked as types. Under the label C’. opacicollis, Macl., are two specimens which are two different species. Denoting these by A and B respec- tively, A has the prothorax purple and blue (the former pre- dominant), the elytra variegated, suture golden, then purple, green, and again golden-metallic at the sides, the seriate punctures are larger than in B, with the intervals distinctly punctate, and tarsal vestiture black. In B the prothorax is metallic-black, the elytra blue, with purple at the suture and golden-green at the sides, the seriate punctures smaller than in A and subelongate, the intervals scarcely perceptibly punctate, while the tarsal vestiture is red. A is the species considered by Blackburn as ('. opacicollis. It is one of the commonest species in South Queensland and Northern New South Wales, and is probably C. vinosus, Pasc., and C. resplendens, Boisd. B is the species described by Blackburn as C. hunterensis. From Macleay’s description the words “Thorax brassy-black, opaque, and minutely punctate,” “Hytra . . . of a purplish colour, becoming green to- wards the sides . . . . . eight rows of small, closely- placed, subelongate punctures” clearly point to B as the type described, since the seriate punctures in A are not at all elongate, and the thorax is not at all black. C’. grandis, Macl. In Blackburn’s table, this is placed under the group with “tarsal vestiture black.’ The type specimen has the tarsal vestiture yellow. C'. obsoletus, Macl.=C. fastuosus, Germ. There are some slight colour distinctions, and the Queensland specimen is rather larger than specimens (identified as C. fastwosus by Blackburn) from South Australia. Confluens, Blkb., is the same species, the distinction drawn by its author is, I think, only individual variety. C’. rufipes, Macl. The type specimen has the pronotum distinctly dark-blue (described as having “thorax black’). It is of a much darker shade than that of the elytra. The tarsi are black above, clothed with reddish hair. Specimens from Cunnamulla, given me by Mr. Lea, are identical. A specimen compared with type of nigritarsis, Pasc., proves its synonymy with that species. 9g C. picipes, Macl. There are two specimens under the label, but evidently the same species. The elytra are green, with larger seriate punctures than in (’. rufipes, the tarsi are piceous above, clothed below with pale-red or yellow hair. I have specimens taken near Brisbane by myself, others from Narromine (N.S.W.) taken by Mr. Sloane, that correspond exactly with Macleay’s type, and also with the description of C. jucundus, Blkb. I cannot agree with Mr. Skuse’s opinion given in the note by Blackburn (Proc. Linn. Soc., New South Wales, 1893, p. 87) as to the identity of C. picipes, Macl., and C. rufipes, Macl. The prothorax varies ain colour from blue-black to green. Of a specimen of picipes, Macl., sent to Mr. Blair he writes: “Type (of jucundus, Blkb.) is larger and stouter, but agrees with this specimen in puncturation and in more nitid surface than in ‘nigritarsis.’ ” C. imperialis, Blkb. The tarsi are nigro-setose, with a few reddish hairs interspersed. Mr. Blackburn placed it amongst those with flavo-setose tarsi in his tabulation. My specimens are from Marmor, Queensland, given me by Mr. H. Brown. C. variabilis, Bless., and C. sulcipennis, Hope, were omitted by Gebien in the new catalogue of Junk (Berlin). The former is a very common species in New South Wales, Victoria, and Tasmania. The latter is identical with C. suturalis, Pasc. (vide infra). C. setosus, Blkb., is not very appropriately named, since the setz are extremely fine, especially on the upper-surface. In the co-type lent me by Mr. Blackburn, the setz could be ‘seen only on the epipleure, in other specimens they are visible (with a lens) on the elytra. It is a large, very robust ‘species, brightly metallic-green, with large punctures of a much darker colour—generally blue—but I have one speci- ‘men in which these punctures are purple. C. nobilis, Blkb., of which I have seen a co-type in the Melbourne Museum, is much more evidently setose, though the fact is not mentioned in the description. There is also a mistake as to locality in the case of setosus. This is given as Victoria in the descrip- tion. All the specimens I have seen (and they are many) have come from Cairns or other parts of North Queensland ; Mr. Blackburn’s co-type was labelled Thursday Island. (C. nobilis, Blkb., has much larger punctures in the elytral series, and much finer (scarcely evident) punctures on the pronotum ; otherwise the two species are very similar. C. perlongus, Blkb. In description the elytra are said to be “sat seriatim punctulatis, interstitiis planis.” Ol 7. C. hunterensis, Blkb.=C. opacicollis, Macl. 8. C. blackburn, Geb. =C. interioris, Blkb. 9.

C. rugosus, Germ.=C’. puncticollis, Hope. 20. (2) C. cresus, Blkb.=C. mercurius, Blkb. The last named in each case has the priority, though in the case of Boisduval’s species, columbinus and resplendens, their determination is too doubtful to allow their names to ‘stand. C. cupreus, Fab., was wrongly determined by Blackburn. . The species determined by Blackburn as ecupreus I have described as CV. maximus. C. cupricollis, Hope. Mr. Blair has examined the type from Melville Island, and writes: “Cupricollis, Hope=semi- ticus, Pasc=smaragdulus, Fab. Cwpricolle type is unique in the peculiar purplish-bloom almost concealing the green on the elytra and still more marked on the thorax.” (It is a common species in Northern Australia, of which I have seen a large number, which are either green or coppery, as in Pascoe’s description of semiticus. A specimen labelled vigilans by Blackburn in the South Australian Museum is of the latter colour, and cannot be distinguished from semiztzcus, iPasce.—H. J.-C.) C. cupripenmis, Hope. It is satisfactory to set at rest ‘this much-disputed name. Mr. Blair writes: “Cupripennis, Hope=froggatti, Blkb. The two types agree much more nearly with each other than they do with specimens sent.” “This determination also agrees with (1) my own notes taken at the Hope Museum, (2) note by Champion quoted by Black- ‘burn (Proc. Linn. Soc., N.S.W., 1893, p. 70), (3) notes sent ‘me by Commander J. J. Walker. Germar was evidently mis- ‘taken in his determination, and Blackburn was misled by ‘this. I believe C. semiseriatus, Blkb., to be doubtfully dis- tinct from this, though distinguished in Blackburn’s table by ‘the “ocular sulcus.” I have a specimen determined by Black- ‘burn which has a small “sulcus,” but the specimen sent by ‘Mr. Blair compared with type is identical with the C. cupri- -pennis, Hope, sent. C’. laticollis, Blkb. I cannot consider this more than a ‘geographical variety of C. colossus, Blkb. I have specimens ‘from Queensland which differ exactly as the author states; the prothorax in colossus is often very transverse. 12 With regard to the species described by Gebien, there is nothing in his description to distinguish (. blackburm, Geb., from C. interioris, Blkb.; nor is there any doubt in my mind as to the identity of C. bicolor, Geb., with C. viridicollis, W. 8S. Macl., an unusually vividly-coloured and distinct insect. Gebien describes the thorax as “steel-blue,’ while Macleay’s type, which I have examined, has the thorax a dark rich-green, of a kind that is to be little distinguished from some shades of blue. C’. tenuicorms, Geb., must be very near C. longulus, Blkb., and obscurus, Blkb. (which may be only a variety of longulus), but its apparently impunctate elytral interstices and some differences in the antennz would appear to dis- tinguish these; while Jongulus can only be distinguished from longipennis, Hope (see below), by its slightly differently shaped prothorax and the stronger interstitial punctures of elytra. C. rugosus, Germ.=C. puncticollis, Hope. Germar seems to have considered rugosus as synonymous with sulci pennis, Hope, but Mr. Blair tells me that the last is identical with sutwralis, Pasc., a species whose interstices of elytra are almost impunctate. The size of rwgosus, “magnitudine precedentis” (the disputed cupripennis, Germ.), and the words “‘crebre transversim rugulosa’”’ as applied to the elytra point to puncticollis, Hope, rather than to sulevpennis. C’. longipennis, Hope, was wrongly identified by Black- burn. Mr. Blair writes: ‘“Longipennis agrees with symilis in all the differences mentioned [by Blackburn in his descrip- tion of the latter.—n.J3.c.]. He was no doubt led astray by Hope’s leaving ‘Adelaide’ as the suggested locality for long- penne in spite of ‘S.R.’ on his own label.” I therefore pro- pose the name cyaniventris for the Adelaide species described by Blackburn as longipennis (Proc. Linn. Soc., 1892, p. 456). The specimen sent me, as compared with type of symilis, Blkb., and longipennis, Hope, has a black pronotum, as stated by Hope, the same being vari-coloured metallic in cyaniventris, a fact not noted by Blackburn in his description of semalis when giving its distinctions from the Adelaide species. C. meyricki, Blkb., is apparently only distinguished from C’. iridiventris, Blkb., by the presence of a “sat augusto”’ ocular sulcus in the description, the same said to be “‘fovei- form” in the table. My specimen of C. meyricki was com- pared with a specimen from the Elder Expedition in the South Australian Museum labelled by Blackburn. The ocular sulcus is scarcely defined, and is unsatisfactory as a dis- tinguishing character in this case. ° 13 C. arthuri, Blkb., seems to me only a variety of C. intermedius, Blkb., if my specimens are correctly identified. I have ©. arthuri taken in Brisbane and compared with co- types in Mr. Lea’s collection. These exactly correspond with specimens of C’. intermedius, Blkb., sent by Mr. Blair, com- pared with type. C. vinosus, Pasc., is the species identified for me by Blackburn as probably C. resplendens, Bois., but on what evidence I do not know. C. suturalis, Pasc.=C. sulcipennis, Hope, fide Blair, who has compared the types. C. cresus, Blkb. Mr. Blair notes the slight difference in the width between the eyes of cresus and mercurius, to- gether with some colour difference, but he concludes: “Should be inclined to doubt specific distinction of crwsus and mer- curius, but have only unique type of each.” C. sumius, Blkb. I cannot consider this otherwise than a variety of the widely-distributed C. affinis, Bless. Like all common species the varieties are very puzzling, and I have often seen specimens of affinis that correspond to the descrip- tion of sumius. This is confirmed by the specimen which Mr. Blair sends as compared with type of simius, which I have no hesitation in calling (’. affinis, Bless. The following are the descriptions of the new species : — CHALCOPTERUS CUPRIVENTRIS, Nn. Sp. Elongate ovate, head and pronotum bronze-green (the former sometimes more obscure), elytra purple (sometimes with coppery reflections), with the suture and punctures green, prosternum black, rest of the under-side metallic-green or copper, coxz and base of femora reddish, legs black, tarsal vestiture yellow. Head closely punctate, eyes distant the length of basal joint of antennz and bordered by a fine sulcus, antennze with joint three equal to fourth and fifth combined, seventh to tenth successively longer and thicker than the pre- ceding, -eleventh more elongate but narrower than tenth. Prothorax truncate at apex, slightly sinuate at base, twice as wide at base as at apex, sides arcuately converging to apex, anterior angles widely obtuse, posterior (seen from above) acute, irregularly but distantly punctate with indications of a smooth medial line. Scutellum triangular, greenish, smooth. EHlytra convex, subparallel, wider than prothorax, striate punctate, punctures on middle series small, larger on lateral series, rather closely set (about four punctures to the width of an interval), intervals flat on disc, very slightly convex towards sides, minutely but evidently 14 punctate; metasternwm channelled and punctate, depressed near base; abdomen rugosely punctate. Dimensions— 15-18 x 75-9 mm. Hab.—Queensland: Townsville (F. Dodd). Seven specimens examined, sent by Mr. H. Griffith, of Adelaide ; alsoin Brussels Museum. The combination of large size, uniform coloration of elytra, flavo-setose tarsi and metallic pronotum and underside makes this species easy to determine. Itis, perhaps, nearest C. leai, Blkb., and C. velu- tinus, W. S. Macl.; but C. leai (of which I have seen co- types) is differently coloured with much coarser sculpture of elytra, while velutinus (of which I know the type) has the under-side black eyes more approximate inter alia. In general form it is near C. longulus, Blkb., C. leat, Blkb., and C. brevipes, Blkb. The striz are not deep, but evident when viewed sideways, and give an elongate appearance to the punctures, which are placed and are of the same average size as in C. widicolor, Bless., though finer in the middle series. The metallic colour of the punctures is not constant, though strongly marked in four of the specimens. Norte. C. cupreus, Fab. The above species is very near cuprews, Fab., and is the insect sent by Mr. Blair as the nearest he could find to the Fabrician type. Mr. Blair writes on the sub- ject of cupreus:—‘‘Type remains unique. Compared with enclosed it is somewhat smaller (15 x 74 mm.), and I should say a little less elongate, though as the elytra are rather widely open it is difficult to judge. The pronotum is less convex, punctured about as strongly, though more sparingly, the punctures becoming smaller and sparser anteriorly; in colour it has a tarnished appearance, broadly blue round the margins shading into purple, and greenish on the disc, this is probably largely due to age, it is semi-opaque as in specimen ; the elytra are a little more nitid, shining coppery and brassy, and blackish towards the apex; they are seriately punctate, with inter- stices quite flat with fewer and finer sharper punctures, the punctures of the series are about as large, rather sharper and a little wider apart, with the series not at all impressed, the two outer series disappear a little below the level of the pin. The under-side is black, about as nitid, but with no metallic colour; tarsal vestiture fulvous, the distance between the eyes a little greater; ocular sulci are present below the eyes, but not well developed, and they do not extend between the eyes.” While some specimens of the species I took for cupreus, Fab., have the under-side obscure, or black, there is still a strong presumption that either C. cupreus is a rare 15 and unique specimen, or that it is one of the later described species. It is possible that the author has misled some col- lectors in the confusion of cwpriventris with cupreus. CHALCOPTERUS PUNCTICOLLIS, Hope. Slightly obovate, head, underside, legs, and tarsal cloth- ing black, pronotum dark metallic-green (in old specimens black), sometimes with slight purple reflections, elytra vari- coloured, chiefly cyaneous, the sutural region more or less golden or purple, sides and epipleure purple. Head closely and strongly punctate, eyes scarcely sul- cate, separated by a space equal to the length of the basal joint of antenna, antenne with joint three nearly as long as fourth and fifth combined, sixth to tenth subequal in length but successively wider, eleventh acuminate. Pronotwm much wider at base than at apex, sides arcuate, the lateral carina seen from above throughout, anterior angles produced, posterior obtuse, disc rather strongly, not closely punctate, with a fine levigate central line. Hlytra wider than prothorax at base, very little convex, widest behind middle, striate punctate, each elytron with eight striz continuous from base to apex (besides a short scutellary stria), more deeply impressed at sides and apex, the punctures therein large, round, and close (larger and much closer than in C. iridicolor, Bless.), intervals convex, closely and strongly punctate. Abdomen and sides of metasternum strongly punctate, the prosternum coarsely, their episterna more finely punctate; hind tarsi with basal joint nearly as long as the rest combined, claws red. Dimensions—11-16 x 6-82 mm. Hab.—Western Australia: Perth. A common species, found in most collections, differing from CU. purpureus, Germ., by its greater size, arcuate thorax, darker colour, and stronger punctuation of its upper-surface, while swtwralis, Pasc., has a shining-black prothorax, and the intervals of elytra almost impunctate. CHALCOPTERUS MAXIMUS, 0. Sp. Widely ovate, head and pronotum metallic—sometimes coppery—elytra purple and green intermixed, the suture, lines of punctures, and epipleure greenish, sides golden-green, under-side, legs, antenne, and tarsal clothing black. Head closely, rather finely punctate, eyes without definite sulcus, space between them as wide as the basal antennal joint; antenne very stout, rather short, scarcely enlarged apically, joint three shorter than fourth and _ fifth combined, sixth widest of all, shorter then the succeeding, seventh to tenth subequal, eleventh nearly as long as 16 and narrower than tenth. Prothorax 44 x 9 mm., twice as wide at base as at apex, nearly straight in front, bisinuate at base, sides little narrowed on basal half, abruptly and sub- sinuately narrowed to the widely obtuse anterior angles, pos- terior angles (seen from above) subrectangular, lateral mar- gins evident throughout from above, disc closely, not strongly, punctate, the median line more or less visible. Scuwtellum transverse triangular, metallic. Hlytra 19 x 114 mm., of same width as prothorax at base, very convex; the highest point of curve (seen from the side) in front of middle, widest behind middle; seriate-punctate, the punctures in series close and small near suture (of the same size as in C’. iridicolor, Bless.), larger towards the sides and clearly defined to the apex; intervals quite flat everywhere, closely and rather strongly punctate (stronger than in C. iridicolor, Bless.). Abdomen finely striolate, flanks of sternum with some larger punctures, prosternum carinate; posterior tarsi with joints one and four of equal length. Dimensions—19-23 x 10-134 mm. Hab.—North Queensland: Endeavour River. This is the species considered erroneously as C’. cupreus, Fab., by Blackburn, and is the largest Chalcopterus known to me. The general colour and form of C’. maximus is nearest C. cupripenms, Hope (=froggatti, Blkb.), especially in its wide, somewhat explanate prothorax, and its mingled colours, with greenish suture. The coppery pronotum is sometimes obscured by age or alcohol, and appears black. In my two fresher specimens the greenish line of punctures is in marked con- trast with the more coppery intervals. Types in the author’s collection. CHALCOPTERUS CSAR, 0. sp. Convex, elongate-ovate, head and prothorax metallic- green and purple, elytra with brilliantly variegated colours arranged in vittz in the following order: the suture golden, then stripes of purple, blue, golden-green, purple, green, lastly the extreme border narrowly golden; the prosternum also slightly metallic (in one specimen brightly so). Abdomen, legs, antennz. nitid black, tarsal vestiture black, with some fine reddish hairs on apical-joint. Head. deeply, closely punctate, distance between eyes greater than the basal joint of the antenne, without clearly- defined ocular sulcus, antennz much longer and less enlarged at apex in male than in female, third joint longer than first and second combined, and fully as long as the fourth and fifth combined, fourth shorter than fifth, eighth to tenth evidently shorter than the preceding, joint eleven longer and more acuminate. in male, shorter and more obtuse in female. 1G Prothorax widest at base, base twice the width of apex (7 and 3°55 mm. respectively), apex truncate, base sublobate, sides arcutely converging from base to apex, anterior angles obtuse, posterior (seen from above) acute, (from the sides) obtuse, lateral carina not, or very little, evident from above; dise distinctly but not coarsely punctate (as in CU. superbus, Blkb.), punctures deep and fairly close. Scutellum triangular, metallic and nitid, impunctate. LHlytra seriate- punctate, each with eight rows, besides the scutellary and lateral rows, of small, deep, evenly-placed punctures, at inter- vals of the diameter of one of them; the intervals quite flat, closely punctate with punctures not much smaller than those in the series, both seriate and interstitical punctures larger and more clearly differentiated than those in (. affinis, Bless. Abdomen closely punctate, finely strigose on basal segments, metasternum suleate behind, carinate in front, prosternum coarsely punctate, posterior tarsi with basal joint as long as the rest combined. JDimensions—Male, 20 x 10°5 mm.; female, 21 x 11°5 mm. Hab.—Western Australia: Sandstone (C. J. Clayton) ; North-Western Australia (C. French). Four specimens are under examination. This is perhaps the most beautiful of all the species of this genus, as well as one of the largest. It is readily separated from its allies by the combination of large size, coloured thorax, head, and prosternum, elytra splendidly variegated in vittz, intervals flat and strongly punctate, the elytral punctures small in pro- portion to the dimensions. It is perhaps nearest to C. rugosi- pennms, Macl., in general appearance, but differs widely in the size of the punctures. The outline of the elytra, seen from the side, is an even, gentle curve, with the highest point near the middle. The male is more convex, with the sides more parallel, the female being slightly widened behind the middle. Types in the author’s collection. CHALCOPTERUS GILESI, n. sp. EKlongate-ovate, elytra subcylindric and parallel, head and prothorax dull- black, under-side and legs nitid-black, apical- joints of antenne pitchy- -brown, tarsal vestiture red; elytra splendidly variegated in longitudinal vittz in the following order: suture narrowly purple, intervals one and two blue, third and fourth green or golden, shading off to purple, then green, purple, with extreme sides and epipleure golden or green. Head distinctly, closely punctate, less closely on forehead than on episterna, eyes separated by a space greater than the length of the antennal basal joint, without definite ocular 18 sulcus: antenne slightly enlarged towards apex, joint three about equal to first and second combined and less than fourth and fifth combined, fourth to seventh equal, eighth to eleventh very little shorter than preceding, eleventh ovate- acuminate. Prothorax 3°55 x 55 mm., moderately convex, and little narrowed anteriorly, truncate at apex, sublobate at base, sides (seen from above) with posterior two-thirds nearly straight, with the lateral carina evident, seen from the sides. evenly, but not widely, rounded, all angles widely obtuse, under a lens seen to be finely, not closely nor deeply, punctate. Elytra nearly twice as long as wide, subparallel and convex, deeply striate-punctate, the intervals strongly convex, seriate punctures large, round, deeply impressed, separated evenly by a distance of the diameter of one, becoming larger and less hidden in the striz towards the sides, and smaller to- wards the base, both striz and punctures deeply impressed to the apex. (The seriate punctures very much as in C. plutus, Blkb.)—intervals almost levigate and nitid. Abdo- men strongly strigose, femora and metasternum strongly punctate, prosternum very tumid and carinate in the middle, posterior tarsi with basal joint not as long as the rest combined. Dimensions—15-17 x 6°5-7°5 mm. Hab.—North-Western Australia: Condon (H.. Giles). A very handsome species, of which several specimens, three of which are now before me, were sent by that very capable naturalist, Mr. Henry Giles, of the Zoological Gar- dens, Perth, and taken by him at Condon. A specimen sent to the Rev. T. Blackburn was returned with the label “unknown to me.” It is very near (. costatus, Blkb., in shape and general appearance (of which I have seen a co- type), but differs in its more variegated and vittate arrange- ment of colours, and in the considerably smaller punctures. of the elytral series. Also near (. puncticollis, Hope, so far as the convexity of intervals and the depth of striz are con- cerned; but Hope’s species is much less brilliantly coloured, with the interstitial punctures very strong. C. giles: is not very near C. zonatus, Blkb., though standing next to it in my tabulation. CHALCOPTERUS DODDI, 0. sp. Ovate, convex; head, prothorax, under-side, legs, and basal joints of antennz nitid-black, apical-joints of antennz: piceous; elytra green at the suture and base of punctures, otherwise nitid-coppery (with a tinge of green), epipleure green and purple, tarsal clothing red. Head closely punctate, eyes separated by a space scarcely equal to the basal joint of antennz, without ocular sulcus, an-- tenne manifestly enlarged towards apex, joint three about. 19 equal to first and second combined, less than fourth and fifth combined, fourth to eleventh subequal in length, seventh to tenth increasingly wider. Prothorax 35 x 6 mm., truncate at apex, sublobate at base, sides (seen from above) evenly, arcuately converging from base to apex, (seen from the side) more strongly transverse and rounded behind the middle, apical part of lateral carina only evident from above; disc distinctly irregularly punctate (less closely than in C. catenulatus, Blkb.), a levigate central line near base only, all angles widely obtuse (seen from above the posterior angles subrectangular). Scutellum triangular, metallic, and nitid. Elytra regularly ovate, longitudinally more convex than C. catenulatus, Blkb., sides not at all parallel, seriate-punctate, series with large subfoveate punctures, irregular in size, ‘shape, and spacing, becoming smaller at base and near suture, larger at apex and sides (extreme lateral row very small), the intervals flat on centre, irregularly subconvex at sides and apex, finely but distinctly punctate. Abdomen with apical segment punctate, other segments closely strigose, metasternum depressed and widely sulcate behind, finely rugose in front, prosternum carinate, posterior tarsi with basal joint less than the rest combined. Dimensions—17 x 85 mm. Hab.—North Queensland: Kuranda (F. P. Dodd). A single specimen received some years ago from Mr. Dodd is superficially most like C. catenulatus, Blkb. It differs in having its prothorax quite black (in C. catenulatus it is coppery), in having no ocular sulcus, in its elytra differently coloured with all the punctures smaller and more irregular (especially towards the sides and apex, where many elongate punctures prevail). The intervals near apex are transversely ridged, and the interstitial punctures are very fine. This ‘species is more coarsely punctured in the series than any other known to me except CU. catenulatus, Blkb. Type in the author’s collection. CHALCOPTERUS ANGUSTICOLLIS, n. sp. Very elongate and narrow, widened rather strongly be- hind the middle, head, prothorax, under-side, legs, and basa] half of antenne nitid-black, apical-half of antenne opaque and setose, elytra with alternate, irregular stripes of coppery- purple, blue or green, extreme sides (in one example the suture also) slightly golden, colours not definitely in vitte, tarsi nigro-setose. Head finely and closely punctate, eyes unusually widely separated, by space greater than the length of basal joint of antenne, ocular sulcus not clearly defined. Antenne thick, 20 slightly enlarged at apex, joint three as long as first and second combined, shorter than fourth and fifth combined, fourth and sixth equal, seventh to eleventh setose and shorter than preceding. Prothorax 3 x 4:5 mm., width at apex equal to length, truncate at apex slightly sinuate at base, sides (from above) almost straightly converging from base to apex, (seen sideways) lightly arcuate, all angles obtuse, clearly, regularly punctate without any indication of central line, a very light foveate impression at apex in the middle. Scutellum black, triangular, and impunctate. JHlytra elongate-obovate, moderately convex, sides widening behind the middle, seriate-punctate, with lines of different-sized punctures rather widely separated, and less strongly impressed and smaller at base and apex, larger and deeper on sides; intervals flat on centre, subconvex at sides, closely and evi- dently punctate. Abdomen closely, finely punctate, scarcely at all strigose, metasternum with larger punctures, close at the flanks, sparse at the centre; prosternum carinate, basal joint of hind tarsi as long as the rest combined. Dimen- sions—15 x 7 mm. Hab.—North Queensland. - Two specimens sent by Mr. C. French, labelled North Queensland, are peculiar in the narrow, elongate form of the prothorax, the base of which is one and a half times the width of the apex, and the elongate-obovate elytra. The seriate punctures are very irregular in size and distance apart, but in general are larger and more distant than those in C. variabilis, Bless.; the interstitial are slightly finer and less close than the corresponding punctures in varzabilis. Both sexes are present. The eyes are at least as widely, or more widely, separated than in (. howitti, Pasc. It is near C. per- longus, Blkb., in dimensions and colour (of which I have a co-type, kindly given me by Mr. Blackburn), but it is easily distinguished from Blackburn’s species by its coarser seriate and interstitial punctures, and the wider space between the eyes. Types in the author’s collection. CHALCOPTERUS ELONGATUS, n. Sp. Elongate-ovate, cylindric; head and prothorax opaque- black, antenne, abdomen, and legs nitid-black, sternum slightly metallic, elytra varicoloured, the suture purple, disc blue and green, then widely purple, with extreme sides and epipleure green or golden, the colours more or less merged, not in distinct vitte; tarsal vestiture black. Head, eyes separated by a distance equal to the length of basal joint of antennz, ocular sulcus not defined, antennz having joint three greater than first and second combined, 21 less than fourth and fifth combined, fourth to eighth sub- equal, remaining joints wanting. Prothorar 4 x 2°5 mm. narrow and truncate at apex, slightly sinuous at base, sides (seen from above) almost straightly converging from base to apex, (from side-view) moderately and evenly arcuate, all angles obtuse (seen from above, posterior angles appear rectangular); distinctly, evenly, punctate, with evident levigate central line. Scutellum black, triangular, im- punctate. Hlytra elongate and cylindric, slightly enlarged behind the middle; seriate-punctate, with punctures of even size and distance apart; intervals quite flat and strongly punctate (both seriate and interstitial punctures very much as in C. variabilis, Bless., but the former more even in size and more close, the latter a little finer). Abdomen finely and regularly punctate, the flanks more strongly so, meta- sternum sparsely punctate at the sides only, prosternum with a small carina, posterior tarsi with basal joint shorter than the rest combined. Dimenstons—13-14 x 6°5 mm. Hab.—Queensland. Three specimens (with mutilated antennz) were given me by Mr. A. M. Lea. The species evidently differs from C. cylindricus, Blkb., by its black tarsal clothing and the - finer seriate punctures of the elytra (which in cylindricus re- semble the intermediate rows of C. punctipennis, Macl.). The colours are not exceptionally brilliant, as is the case in C. cylindricus, which, moreover, is slightly narrower than the above, with the prothorax a different shape. It differs from C. perlongus, Blkb., in its duller black, shorter, and more rounded prothorax, shorter and more convex (longitudinally) elytra, with the interstitial punctures stronger. Types in the author’s collection. CHALCOPTERUS PRISMATICUS, Nn. sp. EHlongate-ovate, parallel, head, pronotum, and under- side very nitid-black, elytra splendidly versicolorous in vitte, 1.e., suture purple, then one interstice blue, next two inter- stices gold or greenish, then purple, gold, or green, with shoulders, sides, and epipleure blue. Head densely punctate, without levigate intervals, the punctures round, deep, and neither rugose nor confluent ; eyes widely separated (more widely than in C. affinis, Bless.), with- out ocular sulcus; antenne long, joint three longer than first and second combined, and nearly, or quite, as long as fourth and fifth combined, fourth to eleventh of nearly equal length, evidently widened towards apex. Prothorax3 x 5 mm., very convex, apex truncate, base slightly lobate in the middle, sides rather widely and evenly rounded and arcuately converging 29 ‘to apex, all angles really obtuse, though seen from above the posterior angles apparently rectangular; distinctly punctate, the punctures smaller and less dense than on head, without defined levigate portion or any vestige of middle line. Elytra moderately convex (less so than in C’. cylindricus, Blkb.), its outline (seen from the side) rather straight, slightly wider than and four times as long as the prothorax ; strongly striate- punctate, the intervals costiform, punctures in striz large, - close, and regular, slightly increasing in size from the suture ‘outwards, the intervals between the punctures less than the ‘diameter of one, their size larger than in C. punctipennis, -Macl., intervals minutely but distinctly punctate. Abdomen finely rugose and punctate, sternum punctate only, prosternum -carinate, legs very nitid and finely punctate, tarsi thickly rufo-setose, hind tarsi with basal joint nearly as long as the rest combined. Dimensions—14 x 7 mm. Hab.—North-West Queensland: Camooweal. Two specimens, both apparently female, sent to Dr. E. W. Ferguson, and generously presented to the author, add an exceptionally beautiful species to the genus. It is easily ‘distinguished by its combination of deeply-striated elytra, brilliant colours, nitid surface, wide eye interval, and rufo- ‘setose tarsi. Wider and less convex than C’. cylindricus, its -colour separates it at once from (’. costatus, Blkb., near which it stands in my table. Type in the author’s collection. CHALCOPTERUS IRIDESCENS, Nn. sp. Elongate, subparallel, convex; mouth purple and blue, ‘front and vertex coppery-purple, pronotum bright burnished- copper, elytra variegated, the suture bright-gold, then a nar- row strip of bright-purple (these colours forming an elongate patch, not in vittz nor continuous to apex), shoulders bronze, the rest of elytra a brilliant iridescent-blue, changing to green or gold, according to the light reflected ; under-side brilliantly nitid and variegated, the central portions blue or green with ‘purple reflections, epimera and prosternum purple. Legs deep purple-blue. Tarsi with yellow clothing. Head closely and evidently punctate, eyes distant, ‘slightly less than the length of the basal joint of antenna, antenne widening to apex, joint three shorter than fourth and fifth combined, sixth to tenth gradually longer and wider, eleventh longest cylindrical. Pronotum truncate in front, sinuate behind, base less than twice as wide as apex, ‘sides arcuately converging to apex, all angles obtuse and rounded, disc impunctate and mirror-like. Scutellum ‘triangular and depressed. JHlytra wider than prothorax, «convex transversely and more than usually so longitudinally, 23 with apex somewhat acuminate; seriate-punctate (punctures sometimes connected by very fine striz), the punctures in strie small, evenly and distantly placed (smaller than in C. tridicolor, Bless., or C. variabilis, Bless.), the series evanescent towards apex, intervals flat and sparsely dotted with very minute punctures (only visible under a lens). Abdomen minutely punctate, metasternum obliquely striolate. Dimen- sions—14 x 7 mm. Hab.—South Australia: Nullarbor Plains (Eucla district). A single specimen, kindly given me by Mr. C. French, is the most brilliantly-coloured Chalcopterus known to me. The colours are so elusive that it is difficult to describe them accurately. The under-side is as brilliant as the upper- surface. In size, form, and colour it is nearest C. meyrickz, Blkb. (of which I have seen a co-type in the South Australian Museum), but it differs in the following particulars from C. meyricki: (1) Colours more brilliant and varied; (2) eyes less widely separated; (3) seriate-punctures much smaller, more distant, intervals distinctly though minutely punctate ; (4) tarsi with yellow clothing. Type in the author’s collection. CHALCOPTERUS LATIFRONS, 0. Sp. Hlongate-ovate, subparallel, depressed; head, pronotum, under-side, and legs black, moderately nitid, elytra variegated, suture and sides green, the greater part of disc purple, or green suffused with purple. Tarsal clothing black. Head densely punctate, space between eyes wider than the length of the basal joint of antenna (wider than in C. howittu, Pasc.), antenne stout and gradually thickened out- wards, third about as long as fourth and fifth combined, four apical-joints subequal and shorter than the preceding joints. Prothoraz twice as wide as long, slightly sinuate at apex and base, sides evenly but arcuately converging to apex, disc closely punctate and very finely rugose, smooth medial line evident for the greater part, anterior angles a little produced, widely obtuse, posterior angles (seen from above) acute. Elytra of the same width as prothorax at base, sides parallel for the greater part, depressed ; seriate-punctate; the punc- tures in series moderately large and closely set (as large as in C. variabilis, Bless., but much closer), intervals very coarsely and densely punctate, and slightly rugose. Abdomen nitid, closely striolate and punctate, metasternum coarsely punctate and obliquely-strigose. Damensions—16 x 8 mm. Hab.—Western Australia: Shark Bay and Murchison River. | Four specimens, from Mr. C. French, are not very near any of those described that combine black pronotum, obscure 24 elytral colours with black tarsal clothing. In form near C. lea, Blkb., and C. obscurus, Blkb. The punctures of the intervals are coarser and deeper than those in C. variabilis, Bless., and are unusually strong. The eyes are exceptionally widely separated, while the outline, seen sideways, shows less convexity than in any other species known to me. Type in the author’s collection. CHALCOPTERUS CYANEUS, ND. sp. Shortly oval, moderately convex, head, legs, and under- side black, pronotum dark-blue, very nitid, elytra nitid-blue, shoulders and sides with metallic reflections, antennz piceous, tarsal clothing yellow. Head finely punctate, eyes widely separated (as in C. howittu, Pasc.), antennz with basal joints slender, apical- joints much thickened, third as long as fourth and fifth com- bined, sixth to eleventh successively longer, eighth to eleventh much thicker than preceding. /Prothorax apex truncate, base slightly sinuate, sides well rounded and converging to apex, all angles obtuse and rounded, twice as wide at base as at apex, closely and finely punctate, with faint indication of a smooth medial line in front. Hlytra wider than prothorax at base, oval, convex, humeri rather prominent; seriate- punctate, intervals quite flat; the seriate punctures deep, round, and rather close (four to the space of an interval), intervals finely but distinctly punctate; under-side very finely striolate. Dimensions—11 x 54 mm. Hab.—North-Western Australia. A single specimen in my collection from a forgotten source. Amongst the species which combine blue pronotum and elytra, with yellow clothing to the tarsi, it is nearest to C. pulcher, Blkb., and C. hartmeyert, Geb. From both it differs in its much more nitid colour and stronger punctuation of pronotum and elytra, besides being smaller. The form is like C. palmerstoni, Blkb., or C. amethystinus, Fab.; the punctures of elytra are arranged somewhat as in CU’. purpureus, Germ. Type in the author’s collection. CHALCOPTERUS SERICATUS, N. sp. Ovate convex, head, pronotum, under-side, and legs black, elytra rose-purple, with sides and epipleure green or blue, tarsal clothing red. Head scarcely, or very finely, punctate, eyes with small sulcus on inner margin, and separated by a distance equal to the length of first joint of antennz, antenne with joint three nearly as long as fourth and fifth combined, sixth to eleventh subequal in length, but successively slightly widen- ing. Prothorax considerably (not twice) wider at base than 25 apex, the former bisinuate, the latter arcuate, sides widely rounded (seen from the sides), all angles obtuse, disc finely punctate, with a smooth medial line and a fovea on each side near the middle of disc. Scwtellum black, minutely punctate. Elytra very convex (as in C. affinis, Bless.), finely striate- punctate, the seriate punctures close together, distinctly larger than in (. affinis, and lying in shallow striz, clearly defined throughout except near base, intervals everywhere quite flat and impunctate, and very finely transversely rugose, giving a silky opaque appearance. Abdomen finely striolate. Dimensions—12-13 x 6-6} mm. Hab.—North Queensland: Coen district (H. Hacker) ; Endeavour River (G. Masters). Two specimens examined—one given me by Mr. Hacker some years ago, the other was amongst some duplicates of the late Mr. Masters—are evidently undescribed. Amongst the species which combine black pronotum, with red- or yellow-clad tarsi only mundus, Blkb., acutangulus, Blkb., and minor, Blkb., could possibly be confused with it; but the first two of these have their elytral intervals more or less punctate, while in minor they are almost smooth, while none of them are striate.

[Read September 11, 1913.] The subfamily Cryptorhynchides contains a larger number of Australian weevils than any other. In the heavily-timbered parts of Australia, and especially in Queens- land, they occur in amazing numbers; but as most of the species are strictly nocturnal in habits, are mostly of dingy colours, and frequently of small size, they are usually passed over by collectors, unless specially looked for. Till recently there were but few species of the subfamily in the Museum, but that institution having acquired the major portion of the late Rev. T. Blackburn’s collection, in which were many species of the subfamily, and having myself taken many species on a recent trip to Queensland, I have been enabled to describe many new genera and species of the subfamily. During the period when the descriptions were being drawn up some specimens from private collections were also examined, so that, although the types of all the new species remain in the Museum, many of the locality records are based on other than Museum specimens. In addition to the species recorded or described here, there are many others in the collection, but as there was nothing fresh to add regarding these, either as to peculiarities of the specimens or as to fresh localities, it was not considered advisable to record them. MELANTERIUS HYBRIDUS, N. sp. 3. Reddish-castaneous, prothorax and under-surface frequently more or less infuscate. Rather densely clothed with scales varying from whitish to pale-ochreous; under- surface and legs with white scales. Eyes separated almost the width of base of rostrum. Rostrum long and thin; with distinct punctures in feeble rows behind antenne, smaller and more crowded in front of same. Scape thin, fully as long as funicle, inserted one-third from apex of rostrum; first joint of funicle as long as second and third combined. Prothorax feebly transverse; with dense, partially-concealed punctures. Hlytra oblong-cordate, base moderately trisinuate; with rows of rather large, partially-concealed punctures, in moderate strie; interstices 183 mostly wider than punctures, the lateral ones, commencing: with the fifth, more or less distinctly ridged along middle.. Basal segment of abdomen with intercoxal process concave. Femora stout, strongly dentate. Length, 4-5 mm. ¥ Q. Differs in the rostrum having smaller and sparser- punctures, with antenne inserted not quite so close to apex ; intercoxal process of abdomen lhghtly convex; and four front tibiz with spur commencing at summit of apical slope, instead - of at apex itself (as in the male). Hfab.—South Australia: Quorn (Blackburn’s collection) ;. Per taincoln (A. \M. Lea)... Type, 1. 1355. In appearance rather close to Diethusa blackburn, and. the curious apex of the four front tibie of the female much the same, but the under-surface without the curious median line of clothing. Abraded specimens somewhat resemble: similar ones of M@. floridus, and the female tibie are much as figured for those of that species,” but that species has the third interstice carinated. In the present species the fifth is the first to be ridged along middle, and its ridge can only be traced where the surface has been abraded. Although the clothing is somewhat variegated, it is not distinctly spotted. The species might be referred with almost equal propriety to Diethusa or to Melanterius. MELANTERIUS BICALCARATUS, 0. sp. a 3. Dark reddish-brown, in places almost black; antennz- and tarsi paler. Rather sparsely clothed with small pale sete; under-surface and legs with more numerous, stouter, and paler setz. Hyes widely separated. Rostrum long and thin, slightly dilated in front of antenne; with clearly defined but not large punctures, becoming sublinear in arrangement behind. antennz, and not concealed at base. Scape thin, inserted one-third from apex of rostrum and the length of funicle; two basal joints of funicle subequal in length. Prothorar moderately transverse; punctures dense, moderately large, and clearly defined. A#lytra oblong-cordate; with rows of rather large, oblong punctures, becoming small posteriorly ; interstices wider than seriate punctures, the first three ridged posteriorly, but not on basal half, the others with the ridges gradually extended until they are almost continuous through-- out, with fairly numerous punctures becoming seriate in arrangement on most of them. Basal segment of abdomen flattened in middle. Femora stout, moderately dentate; hind tibiz widely notched near apex, the notch supplied with long- sete, four front ones bicalcarate at apex. Length, 6-64 mm. (1) Ann. & Mag. Nat. Hist., vol. xvi. (4 ser.), pl. i., fig. 19. 184 fab.—South Australia: Oodnadatta (Blackburn’s col- lection). Type, I. 1356. The four front tibie are bicalcarate at apex, the spurs are small and touch, but are quite distinct from some direc- tions. Many other species appear at first to have two spurs, but the supposititious second one is usually a fascicle. Others also have the apex really bicalcarate, but the spurs, although not widely separated, are not touching, one marking the apex of the slight subapical sinus, and usually supporting a fascicle, and the other overhanging the apex. Two specimens, apparently females of this species differ in having the eyes closer together (a most unusual feminine character), and the first joint of funicle distinctly longer than the second; hind tibize not notched near apex, the four front ones each with a single spur, rostrum longer, thinner, more shining, with smaller and sparser punctures and antenne inserted almost in middle, and basal segment of abdomen dis- tinctly convex. MELANTERIUS BISERIATUS, HN. sp. Colour and clothing much as in preceding species. Eyes widely separated. Rostrum long and thin; with distinct punctures about base, elsewhere sparse and minute. Scape thin, inserted about three-sevenths from apex of rostrum, somewhat shorter than funicle; first joint of funicle slightly longer than second. Prothorax with punctures much as on preceding species. Hlytra cordate, base not trisinuate, sides rather lightly rounded, with rows of fairly large, sub- oblong punctures, becoming small posteriorly; interstices wide, each with two rows of distinct punctures, ridged along middle, but the ridges very feeble or absent at base. Under- surface with moderately dense punctures, but in a single row on parts of metasternal episterna; each of third and fourth abdominal segments with a single row across middle, basal segment rather strongly convex. Femora stout, moderately dentate. Length, 44-45 mm. Hab.—South Australia: Oodnadatta (Blackburn’s col- lection). Type, I. 1357. The sutural interstice is unusually wide, as nowhere is it narrower than the second, and posteriorly it is wider; it has a median ridge only on the posterior declivity, and even there it is irregular and ill-defined; its punctures are somewhat ~ irregular, although subseriate in arrangement. On all the others the punctures are in two almost regular series. In my table would be associated with interstitialis, incomptus, and tristis, from all of which its larger size and very different elytral punctures will readily distinguish it. The (three) typical specimens are probably all females. 185 MELANTERIUS CARDIOPTERUS, N.. sp. Dark-brown, almost black; rostrum, antenne, and tarsi paler. Upper-surface with minute indistinct sete, under- surface with sparse but more distinct ones, the legs moderately clothed. Eyes widely separated. Rostrum moderately long and lightly curved; with clearly-defined punctures, becoming rather coarse and linear in arrangement behind antenne ; with a distinct median carina. Scape rather thin, inserted two-fifths from apex of rostrum, and the length of funicle; first jomt of funicle longer than second. Prothorax moderately transverse, with fairly large, clearly-defined punctures. SHlytra cordate, shoulders and sides rather strongly rounded, with series of large punctures, becoming small posteriorly ; interstices acutely ridged, except towards. base, but the sutural one only on posterior declivity, the sutural one also with but one row of punctures; the others each with two feeble rows. Basal segment of abdomen flat in middle. Femora moderately stout, strongly dentate. Length, 3-35 mm. Hab.—South Australia: Tumby (Blackburn’s collection) . five, 2. 1558. In general appearance close to legitiumus, but femora without a granule in emargination, prothorax with larger punctures, and elytra with smaller and less clearly-defined ones in the striz. In some respects it is close to parvidens, but that species has smaller femoral teeth, smaller punctures on metasternum and basal segment of abdomen, denser and smaller prothoracic punctures, and somewhat different elytra. The second and third interstices are carinated on the posterior half of the elytra, but the carina on each, instead of being in the middle, as in most species, is placed on the outer side ; this is also the case with the carine of some of the other interstices but less conspicuously so; but several other species have the outer ones similarly carinated. Compositus has the second and third interstices similar, but the sutural punctures are smaller and sparser, and disappear before the middle, and the suture itself is carinated for a greater length; the punctures on the other interstices are much smaller and sparser, and the prothoracic ones are smaller. A specimen from Sea Lake in Victoria (J. C. Goudie) probably belongs to this species, but differs in being larger and with the body parts quite black. MELANTERIUS BARIDIOIDES, Nn. sp. Black, shining; antennze and tarsi reddish. Upper- surface almost glabrous; under-surface and legs sparsely setose. 186 Hyes separated shghtly less than width of base of ‘rostrum. Rostrum long and thin; with not very dense “punctures, but becoming linear in arrangement behind -antenne. Scape inserted slightly nearer apex than base of rostrum, much shorter than funicle; first joint of funicle ‘shghtly longer than second. Prothorar with rather dense, ‘and not very large, but clearly-defined punctures. Hlytra -subcordate, base lightiy trisinuate, sides gently rounded; with rows of not very large, and somewhat distant punctures, becoming smailer and closer together posteriorly ; interstices -almost flat on basal half, acutely ridged posteriorly, each -with two rows of punctures. Basal segment of abdomen -evenly convex. Four hind femora strongly and acutely -dentate, the others edentate. Length, 34 mm. Hab.—North Queensland (Blackburn’s collection) ; Cairns (Hi. Allen); Type, I. 1309: At a glance appears to belong to the Baridudes. In my ‘table of the genus would be associated with porosus, but from ‘that species, and from all others of genus, distinguished by ‘the curious femoral dentition. The typical specimens are probably both females. MELANTERIUS STENOCNEMIS, Nl. Sp. Black, elytra obscurely diluted with red, antenne and ‘tarsi red. Elytra with stout, sulphur-yellow sete or scales ‘condensed into distinct spots; under-surface and legs with rather sparse, whitish sete. LHyes close together. Rostrum moderately long and thin; punctures distinct, becoming larger towards base, but scarcely seriate in arrangement. Scape inserted about one-third from apex of rostrum, not much shorter than funicle; first joint -of funicle slightly longer than second. Prothorax with dense, . clearly-defined, and rather small punctures. Elytra cordate, sides rather strongly rounded; with rows of large punctures, ‘interstices acutely ridged, the first’ only on posterior declivity, the others almost to base, each with a row of small punctures on each side of the ridge, but becoming feeble posteriorly. Abdomen with basal segment depressed in middle, with rather dense punctures; second with dense punctures but apical portion impunctate; third and fourth with minute punctures. Femora stout, strongly dentate, the four hind ones each with a granule in emargination; tibie thin, four front ones with hook cleft at apex, hind ones with hook dentate near base. Length, 44 mm. Hab.—Queensland: Cairns district (F. P. Dodd). Type, RUSSO. 187 A very distinct species, allied to aratus, and with very similar abdomen, but somewhat larger, legs longer, elytral interstices more acutely carinated, and clothing of elytra in more numerous spots, etc. The teeth of the four hind femora are large and obliquely truncate at apex, on the others they are much smaller and acute. MELANTERIUS NIVEODISPERSUS, 0. sp. Dark reddish-brown, in parts (especially the under- surface) almost black; antennz reddish. Moderately densely clothed with light-brown or pale-ochreous scales, variegated with white. Head with dense, partially-concealed punctures. Eyes rather large, separated less than width of rostrum at base. Rostrum rather long and thin, almost parallel-sided; with. rather dense but not very large punctures, partially concealed only at base, and on sides near base; with a feeble median ridge. Scape inserted about two-fifths from apex of rostrum, shorter than funicle; first joint of funicle longer than second. Prothorax rather small and convex, sices strongly rounded, apex half the width of base; with dense, partially-concealed. punctures. Hlytra subcordate, much wider than prothorax,. sides almost parallel to beyond the middle: with rows of large, partially-concealed punctures, alternate imsterstices con-- spicuously ridged along middle, from near base to near apex. Basal segment of abdomen convex in middle. Femora stout, moderately dentate; terminal hook of tibie small. Length, 5 mm. ; Hab.—Western Australia: Cue (H. W. Brown). Type,. T. 1541. Allied to Horidus and costipennis, but alternate inter- stices much more conspicuously elevated ; and clothing, to the naked eye, more greyish. In outlines it is slightly closer to the former than to the latter. On the elytra the white scales are fairly numerous on the basal third and towards the apex, but on the rest of the upper-surface they are sparse and scat- tered singly. On the under-surface and legs they are mostly whitish, but on the sides of the former they are somewhat darker. The type is probably a female. MELANTERIUS SOLITUS, Lea. At the time of description of this species I had but a single specimen to examine. The species, however, is abundant on. species of acacia in South Australia (Port Lincoln, Blanche-- town, Moonta, Kangaroo Island). 188 Specimens in good condition have each elytral interstice marked by a distinct row of whitish sete on each side, the rows quite evenly divided by the median ridges. On slight abrasion, however, the rows become indistinct. The scales in the pro- thoracic punctures do not rise to the general level. The elytra are usually somewhat paler than the pro- thorax. The median carina of the prothorax is usually dis- tinct, but more or less encroached upon by punctures. Of a pair taken in cop, the male has a distinct carina, but. the female is without a trace of one. ‘The difference, however, is not sexual, as it is absent from some males and present on some females. The male has the metasternum and basal segment of abdo- men widely and conjointly concave; in the female the meta- sternum is feebly depressed, but the basal segment of abdomen is convex. The female also has a somewhat longer and thinner rostrum than the male, and with smaller and sparser punc- tures. Her antennz also are inserted less close to the apex. The size ranges from 34-43 mm. MELANTERIUS FLORIDUS, Pase. The curious spine or tooth on each of the four front tibiz of this species, as figured by Pascoe, is sexually variable, being confined to the female. In the male each tibia 1s terminated by an apical tooth of smaller size and starting from the middle of the tibia, instead of from its upper apex. MELANTERIUS SEMIPORCATUS, Er. In my table of the species of Melanterius (Proc. Linn. Soc., N.S.W., 1899, p. 207) this species is placed with those having the femoral emargination normal. As a matter of fact, in the emargination (especially of the front pair) there is often a small supplementary tooth or granule, but (when present) it is always smaller than the similar one of bidentatus (a species which differs in many other respects, however). The large femoral teeth are usually more or less triangular, but on many specimens they are truncated (on the hind femora often con- spicuously so). MELANTERIUS COMPACTUS, Lea. The types of this species have the elytra but little or not at all paler than the prothorax, but on a specimen from Port Esperance and two from Callington and Murray Bridge) the elytra are distinctly paler. The sexes differ in the four front tibie as do the sexes of floridus, except that in the females the apical spurs diverge at a oreater angle. (2) Now first recorded from South Australia. 189 MELANTERIUS TRISTIS, Lea. Two specimens from Hergott Springs certainly appear to belong to but one species, but in my table of the genus the female would be placed with compactus and castaneus, as its second and third elytral interstices are not triangularly raised posteriorly ; while the male would be placed with tristzs. The species is much narrower than compactus or castaneus, and possibly is not ¢7zstis, as the elytral punctures are sparser and smaller, and the interstices are less conspicuously or not at all carinated. It seems best at present, however, to regard the specimens as aberrant ones of ¢trvstis. MELANTERIUS APICALIS, Lea. A male from Cairns differs from the type in having the spur at the apex of each of the middle tibie notched, so that from some directions it appears as two short spurs; the spurs on the hind tibiz are also feebly notched, but on the front pair they are simple. DIETHUSA SUTURALIS, N. sp. d. Reddish-castaneous; head, prothorax, and elytra sometimes infuscate. Moderately clothed with reddish or ochreous scales, more or less feebly variegated; under-surface mostly with whitish scales, but with a line of whitish sete. Rostrum rather long, thin, and almost parallel-sided ; behind antenne with punctures in lines, and leaving a feeble median carina. Scape thin, about the length of funicle, inserted one-third from apex of rostrum: first joint of funicle slightly longer than second and third combined. Prothorac lightly transverse; with dense punctures. Llytra subcordate, base moderately trisinuate;: with large, partially-concealed punctures ; interstices wide, the first acutely carinated through- out, third and fifth moderately ridged on posterior half, the lateral ones almost throughout. Jfetasternum and basal seg- ment of abdomen with a sulcus commencing almost at base of former, and continued almost to apex of latter, and containing the line of sete; apical segment with a shallow impression. Femora stout, strongly dentate. Length, 4-44 mm. Hab.—South Australia (Blackburn’s collection). Type, 1330. Structurally very close to blackburni, but with clothing of upper-surface very different. On the lower-surface the peculiar median clothing also extends to a greater length. In this respect, and also in its acutely bicarinated suture, it agrees with metasternalis, but that species is of more compact form, and with prettily-variegated clothing, its second abdominal 190 segment is somewhat larger, and its metasternal fovea con- siderably larger. DIETHUSA FUNEREA, 0D. sp. Almost black; antenne, tarsi, and tip of rostrum reddish. Densely clothed with sooty scales: most of under-surface and legs with white or whitish scales. Rostrum moderately long, thin, and parallel-sided; basal half with coarse, but more or less concealed punctures; apical half with smaller, but clearly-defined ones. Scape not very thin, inserted almost. in middle of rostrum, much shorter than funicle; basal joint of funicle slightly longer than second. Prothorax lightly transverse, with dense punctures. Hlytra subcordate, base rather strongly trisinuate, with rows of rather small punctures, in narrow striz, the striz distinct, but the punctures almost concealed ; interstices wide, with dense con- cealed punctures, nowhere ridged. Basal segment of abdomen rather strongly convex, apical with a feeble impression. Femora stout, hind pair strongly, middle ones moderately,. front ones lightly dentate; four front tibiz each with apical hook small. Length, 4 mm. Hab. — South Australia: Poonindie (Blackburn’s col- lection). Type, I. 1331. In the rostrum, whose apex when at rest is received into: a slightly concave mesosternal receptacle, instead of passing beyond same, this species agrees with Psydestis and Melan- teriosoma, but the second abdominal segment, although much shorter than the first, is not unusually short, and the eyes are moderately faceted. Too many genera have already been pro- posed at the expense of J/elanterzus, so it seems better to treat the present species as an aberrant member of Diethusa rather than to propose a new genus for its reception. A second speci- men differs from the type in having the elytra (although their clothing is still sooty) and legs reddish. The two evidently belong to but one sex, but I am doubtful as to what that sex 1s. DIETHUSA SILACEA, N. sp. 3d. Reddish-castaneous. Densely clothed with ochreous: scales variegated with golden; becoming whitish on under- surface and legs. Rostrum rather long and thin, very feebly diminishing in width from base to apex; with dense punctures, becoming coarser and linear in arrangement behind antenne, and with a feeble median carina. Scape inserted very slightly nearer apex than base of rostrum, shorter than funicle; first joint. of funicle as long as second and third combined; club rather 191 large. Prothorar moderately transverse, with dense punc- tures. JHlytra subcordate, subhumeral incurvature rather ‘slight; with rows of rather large but partially-concealed ‘punctures, in rather narrow striz; interstices wide, nowhere ridged. Basal segment of abdomen obliquely flattened in middle, apical with a wide shallow depression. Femora stout, strongly dentate. Length, 5 mm. Hab.—Western Australia (Blackburn’s collection). Type, I. 1332. The largest of the genus as yet described. It seems probable that I previously confused females of this species with a male of porphyrea.(5) The three specimens now before me, that I described as such, have the third, fifth, and seventh interstices of elytra not conspicuously ridged, as in the male of that species, but scarcely different to the others, so that it is only on looking at them from in front that they can be noticed to be at all elevated above the others, and they are certainly not ridged. These females differ from the type of the present species in having the rostrum longer, and de- -cidedly thinner and narrowed from insertion of antenne (these distinctly nearer base than apex), with smaller and sparser ‘punctures, and abdomen with basal segment evenly convex. ‘Their golden (on one specimen golden-red) scales form spots amongst the ochreous ones. The type is certainly not porphyrea, however, as it is a male (the rostrum and abdomen are conclusive of this), and it has the elytral interstices very different to those of that species. Its claws are also unusually ‘small and close together, so that, from most directions, each tarsus appears to be terminated by a single claw. DIETHUSA INERMIS, n. sp. 3. Black, antenne, legs, and tip of rostrum reddish. Densely clothed with more or less ochreous scales, varied with ‘spots of stramineous; under-surface and legs mostly with whitish scales. Rostrum moderately long, almost parallel-sided to insertion of antenne, thence somewhat narrowed to apex’; basal half with coarse, partially-concealed punctures, and a narrow median carina; apical half with dense, clearly-defined punctures. Scape inserted about two-fifths from apex of rostrum, somewhat shorter than funicle; first joint of funicle ‘shghtly longer than second. Prothorax moderately trans- verse ; with dense punctures. Hlytra subcordate, base strongly trisinuate, basal half parallel-sided; with rows of oblong (3) Proc. Linn. Soc., N.S.W., 1899, p. 252. 192 punctures, in narrow, deep striz, the striz distinct, but punc- tures almost concealed ; interstices wide, nowhere ridged, with dense and rather coarse but normally quite concealed punc- tures. Basal segment of abdomen obliquely flattened in middle; apical with a wide impression. Femora stout, edentate. Length, 24-3 mm. Q. Differs in having the rostrum longer, more decidedly narrowed in front of antennz (these inserted not so close to apex) with less clothing, smaller and sparser punctures, and about half of it red; basal segment of abdomen evenly convex, and apical not impressed. Hab.—South Australia (Blackburn’s collection and Macleay Museum); Murray Bridge (A. M. Lea). Tyne, [. 1333. This species and tenwirostris and sulfurea are without femoral teeth, and on that account should perhaps be referred to a new genus, but the dentition certainly varies in Diethusa from feeble to strong, and some have the front femora edentate. Moreover, this species in general appearance is extremely close to some of Diethusa, and three specimens of it were previously referred to by me as belonging to coneimna, and they certainly look as if they belonged to that species, but the entire absence of femoral dentition is distinctive. On some specimens the majority of the scales are almost brick-red in colour, with the pale spots strongly contrasted; on others most of the scales are of a dingy-ochreous, with the spots but feebly contrasted. On. the prothorax there are no distinct spots, although the clothing in places varies somewhat in colour. DIETHUSA PALLIDICOLLIS, n. sp. Reddish-castaneous. Densely clothed with white or whitish scales, but on most of elytra more or less ochreous or golden. Head with dense, concealed punctures. Rostrum rather long, moderately wide from base to antenne (which are in- serted at basal two-fifths), but then narrow and thin to apex; towards base with partially-concealed punctures, separated by narrow ridges, elsewhere with minute punctures. Scape about half the length of funicle and club combined. Prothoraz strongly transverse, evenly convex; with dense punctures. Elytra briefly cordate, distinctly wider than prothorax ; with rows of fairly large more or less concealed punctures in dis- tinct strie; interstices wide, with dense concealed punctures. Under-surface with dense concealed punctures. Basal segment of abdomen convex, as long as three following combined, fifth shallowly impressed at apex. Femora stout, strongly dentate. Length, 32-4 mm. 193 /1ab.—Western Australia: Cue (H. W. Brown). Type, I. 1544. In some respects, notably of the rostrum, close to silacea and inequalis, but clothing of prothorax conspicuously dif- ferent to that on most of the elytra. On the prothorax, under- surface, and legs the scales are mostly white, but in places they are more or less feebly stained with ochreous. On the apical half of elytra the scales are more or less pale-ochreous, becoming paler at the tip, but on the basal half they are but little different in colour to the derm on which they rest; the shades of colour, however, gradually run into one another. On the scutellum they are of a snowy-whiteness. The (four) typical specimens are apparently all females. DIETHUSA NODIPENNIS, 0. sp. Reddish-castaneous ; in parts stained with black. Densely clothed with stramineous, or light-ochreous, scales, in places somewhat darker. /lead with concealed punctures. Rostrum moderately long, parallel-sided between base and antenne (which are inserted in almost exact middle), and then strongly narrowed to apex; basal half with partially-concealed punctures and a median carina, elsewhere with small punctures. Scape slightly more than half the length of funicle and club com- bined. Prothorax small, moderately transverse, rather strongly and somewhat unevenly convex ; punctures concealed. Elytra briefly subcordate, much wider than prothorax; with rows of almost concealed punctures, in distinct striz, the latter often deflected by tubercles; interstices with numerous tubercles of various sizes. Under-surface with dense, con- cealed punctures. Basal segment of abdomen convex, as long as three following combined. Femora stout, edentate. Length, 32 mm. | Hab.—Western Australia: Beverley (F. H. du Boulay). Type, I. 1545. The multituberculate elytra and edentate femora render this one of the most distinct species of the allied genera. Its nearest ally is probably the Queensland sulfurea. In size, and to a certain extent in clothing, it resembles Neolybeba remota, but the rostrum, elytra, femora, etc., are very dif- ferent ; the tip of the rostrum and most of the sternal sutures are black. The tubercles are nearly all on the odd interstices, including the sutural one; the largest are on the third and fifth ; on the basal half there are but few, but those of rather large size, but on the apical half they are numerous. The strie, especially the second to fifth, are frequently deflected H 194 by them. The larger ones are usually crowned with scales that are darker than the surrounding ones. The type is probably a female. DieTsusa acuTicosta, Lea. The female of this species has the four front tibiz as in the female of blackburm. A specimen from Port Lincoln exhibits the curious apical dentition quite conspicuously. On the type female the tibiz were clogged with gum, and so the dentition was overlooked. DIETHUSA BLACKBURNI, Lea. The type of this species is clothed with almost uniformly white scales, the feebly-spotted appearance of the elytra being due to somewhat irregular disposition of the scales rather than to shades of colour. It is a female; the male differs in having each of the four front tibiz with the apical tooth in the normal position. The rostrum is shorter, with larger and denser punctures, condensed into strong but partially- concealed rows behind antennz, and the antennz are inserted somewhat nearer its apex. The basal segment of its abdomen is slightly concave (instead of distinctly convex) and has a curious line of stramineous clothing along its middle and con- tinued on to metasternum. DIETHUSA FAMELICA, Lea. The types of this species were described as having the abdomen with “the three median segments so depressed that their lengths can only be seen from the sides’ ; this, however, was due to the apex of the abdomen, in each, being somewhat protruded. On specimens with the abdomen in its normal position the length of the second segment is easily seen, but the third and fourth are depressed below its level and the level of the fifth; and as they are extremely short if the tip of the abdomen is at all free from the elytra (as it fre- quently is) they are almost concealed. The clothing is dense and variable. A specimen from Blackburn’s collection has the scales on the upper-surface dark-brown, but with an appearance as of numerous short whitish stripes (along the striz) on the elytra, and the pro- thorax with a median line and white patches on the sides. Other specimens (from Murray Bridge) have most of the scales pale, but with numerous sooty or dark-brown spots (not symmetrically disposed) on the prothorax and elytra. No two, of the fourteen specimens (including one from Birchip in Victoria) before me, agree in their markings. ee oe 195 NEOMELANTERIUS INTERRUPTUS, HN. Sp. Black, antennz and tarsi red. Clothed with rather long straggling white sete, denser on metasternum, basal segment of abdomen, and legs than elsewhere. Head with dense round punctures. Eyes close together, a narrow impression behind each. Rostrum the length of pro- thorax, almost straight ; basal fourth with three strong caring, separating strong rows of punctures, elsewhere with small punctures. Scape thin, inserted one-third from apex of ros- trum, the length of funicle; first joint of funicle stouter than second, but scarcely longer. Prothorax almost as long as wide ; with dense and rather large, more or less confluent punctures ; with a narrow and continuous median carina. LF/ytra cordate, sides rather strongly rounded, with rows of rather large, some- what distant punctures, becoming small posteriorly; inter- stices more or less acutely carinated. Abdomen with dense and rather coarse punctures on the apical, and the two basal seg- ments; first short and strongly convex, apical with subreni- form impression. /emora moderately stout and rather strongly dentate. Length, 5 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, WEESo! . The elytral omlycme is practically identical with that of carinicollis, but that of the prothorax is very different. The prothoracic punctures are readily seen, but here and there two or three are more or less confluent, in consequence of which there appears to be a few short irreoular carine, but these are very different to the long carine of carinicollis, conspicuous from base to apex, and with the punctures (except at the sides) not in evidence. It also differs from that species in being nar- rower, deep-black, and with somewhat different clothing. The second, fourth, sixth, and eighth interstices are each distinctly carinated near the base, but the carina is then interrupted for a short distance, so that large punctures eupees to be in double rows there. NEoLYBaBA, Blackb.@ This genus is extremely close to Diethusa, and probably should be merged in it. Jt is known only from a single (and _ probably a female) specimen, now in the South Australian Museum. Its eyes are unusually coarsely faceted, more so than in any species of Diethusa known to me, and the second abdominal segment is also larger than in most species of that genus. Its four front tibiz are bicalcarate at apex (a variable feature in both Diethusa and Melanterius), the smaller spur being partially concealed by clothing. (4) Trans. Roy. Soc., S..Aust., 1892, p. 193. H2 196 NEoOLYB£BA REMOTA, Blackb. Among the allies of J/e/anterwus this species is readily identifiable by the fifth interstice on each elytron being sup- plied with a distinct preapical callus. Many of the scales on the upper-surface have, in some lights, a beautiful golden lustre, a fact not mentioned in the original description, but of extremely rare occurrence in the Uryptorhynchides. AONYCHUS STRIATUS, Lea, var. Two specimens from the Northern Territory evidently represent a variety of this species. They differ from the types in having the darker scales absent from the prothorax, except for a feeble spot on each side of the base; on the elytra also they occupy considerably less space than the whitish ones, and form somewhat angular markings about the suture and sides. MECHISTOCERUS MARMOREUS, 0. sp. d. Black, antenne and tarsi red. Densely clothed with scales closely applhed to derm; and with stouter suberect ones. Head with dense and rather coarse punctures. Ocular fovea elongate, rather suddenly enlarged in front. Rostrum long and thin; basal third with coarse partially-concealed punctures, leaving three feeble ridges, elsewhere shining, and with small, clearly-defined punctures. Antenne thin; scape inserted one-third from apex of rostrum, first joint of funicle stouter, but no longer than second. Prothorax lightly trans- verse, sides strongly rounded; with a feeble median carina ; with large and usually distinct punctures. Hlytra elongate- subcordate, about one-third wider than prothorax; with rows of large, but more or less concealed punctures. J/etasternwm distinctly shorter than the following segment; with fairly numerous punctures, including a distinct row on each epis- ternum ; narrowly impressed along middle, but the impression deep and dilated at both ends. Abdomen with sparse punc- tures, some as large as on metasternum, but most of them smaller; basal segment feebly depressed in middle. /emora lightly dentate, the hind ones just passing apex of elytra. Length, 53-75 mm. Or Differs in having the rostrum thinner in front of antenne, much less of the base with coarse punctures, and without median ridges; antennz inserted not so close to apex of rostrum; and basal segment of abdomen gently convex. Hab.—Queensland: Mount Tambourine (A. M. Lea). Type, I. 1459. In my table of the genus would the associated with masters: and dispar; from the farmer it differs in being considerably 197 smaller and narrower, legs shorter, and clothing somewhat different. Its abdominal clothing is very different to that of dispar, and there are many other differences. In its compara- tively short metasternum it agrees with compositus, but the shoulders are wider, abdominal clothing much sparser, punc- tures different, etc. On the elytra the scales are mostly fawn- coloured or of a dingy-brown, largely mottled with irregular sooty patches, and with sparser, pale, irregular spots. Hach interstice has a feeble row of stout suberect scales (usually arising from a feeble granule), and each seriate puncture has a similar scale. On the prothorax the scales are nearly all moderately long, mostly sooty, but with fawn-coloured ones scattered about, and forming three feeble lines. On the under- surface the clothing is pale and sparser and thinner than else- where. On the legs the clothing is of a somewhat brick-red colour and very dense. Five specimens from New South Wales (Dorrigo, Llla- warra, and Otford) are extremely close in general appearance, but differ in having the prothorax more densely clothed, and with less evident punctures; the under-surface with stouter scales, frequently sooty, and the rostrum long and thinner, with the scape inserted not quite so close to apex. They appear to be all females, and probably represent a new species, but I am averse to naming them without knowing the male. MECHISTOCERUS CYLINDRICUS, Nn. sp. Red. Densely clothed. fHlead with coarse concealed punctures. Rostrum (for the genus) rather short; basal third with coarse concealed punctures and three feeble ridges, elsewhere shining and with small, clearly-defined punctures. Scape inserted two-fifths from apex to rostrum; second joint of funicle longer and thinner than first. Prothorax rather strongly transverse, sides strongly rounded, apex about two-thirds the width of base ; median carina feeble; with crowded, partially-concealed punctures. Hlytra narrow and cylindrical, not much wider than widest part of prothorax; with rows of large, almost concealed punctures. Under-surface with dense more or less concealed punctures, including on the metasternal episterna. Metasternum as long as the following segment, rather lightly impressed along middle. Abdomen with first segment some- what flattened in middle, not much longer than second, second slightly longer than third and fourth combined, each of these almost as long as fifth. Legs comparatively short; femora rather strongly dentate, hind ones just extending to apical segment. Length, 6 mm. 198 Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1460. A small, cylindrical species, allied to vulneratus, but smaller and with very different clothing. On the elytra, under-surface, and legs the scales are dense, moderately stout, and almost uniformly pale-stramineous. On the elytra each serlate puncture contains a scale, but it is traceable with diffi- culty, and the interstices are entirely without larger scales amongst the others. On the prothorax the scales are stouter, longer, not quite so dense, and feebly variegated. On the head and base of rostrum they are much as on the elytra, except that they are a trifle darker. The rostrum is no longer than the prothorax. The type is probably a male. MECHISTOCERUS METASTERNALIS, N. sp. Black, antenne and tarsi red. Densely clothed with brick-red scales, in places variegated with sooty-red ones. Head with coarse more or less concealed punctures. Ocular fovea deep and narrow, but dilated in front. Rostrum long and thin, basal fourth with concealed punctures and three ridges, sides to antennz with rather small clearly-defined punctures, elsewhere with minute ones. Scape inserted two- fifths from apex or rostrum; first joint of funicle slightly longer than second. Prothorax moderately transverse, sides rather lightly rounded; with a rather feeble median carina; with crowded partially-concealed punctures. Hlytra sub- cordate, base trisinuate and about one-third wider than prothorax, basal half parallel-sided ; with rows of very large, deep punctures, becoming smaller posteriorly. d/etasternum short; with a wide, deep, and irregular median excavation, each side of which is bounded posteriorly by a raised, shining, densely punctate space; elsewhere with large or very large punctures. Abdomen with basal segment flat in middle, with some moderately large punctures, and some very large ones on each side near coxe ; second segment sloping downwards to apex, with two or three irregular rows of fairly large punctures. Legs rather long; hind femora strongly, the others moderately, dentate; hind ones passing elytra for a short distance. Length, 55-75 mm. Hab.—Queensland: Cairns district (A. M. Lea); Kuranda (G. E. Bryant). Type, I. 1461. Readily distinguished from all previously described species by the metasternum. In build the species resembles duplicatus, cancellatus, and punctiventris. The brick-red scales clothe most of the upper-surface. On the elytra they appear to be feebly fasciate in arrangement, partly owing to the large punctures, and partly to small patches of sooty lee scales; on each interstice there is a row of stouter scales. On the prothorax the scales are suberect, and but few of them are sooty. On the under-surface the scales are sparse and confined to the punctures. The legs are densely clothed. The very large elytral punctures are open behind but somewhat cavernous in front; they vary from almost quadrate to twice as long as wide. The four typical specimens are probably all males. MECHISTOCERUS BASALIS, ll. sp. d. Of a sooty-black, antenne and tarsi red. Rather sparsely clothed, but with a conspicuous short line of pale scales on each side of scutellum. Head with rather coarse, crowded punctures. Ocular fovea long, narrow, and deep. Rostrum long and thin; basal third with rows of large punctures, leaving three median ridges, elsewhere shining and with minute punctures. Scape inserted one-third from apex to rostrum; two basal joints of funicle subequal in length, but the first stouter than the second. Prothorax feebly transverse, basal two-thirds almost parallel-sided, median carina short and feeble; with moderately large but not crowded punctures. Hlytra with base trisinuate and about one-third wider than prothorax ; with rows of large, deep punctures, rapidly becoming smaller posteriorly. Metasternum rather short, with a deep and rather wide median impression dilated posteriorly; with very large punctures or fovee; episterna narrowly impressed throughout. Abdomen with basal segment rather flat in middle; with a few large punctures, and with a row of very large subconnected ones on each side near coxz; second seg- ment with a few fairly large punctures at base and across middle. Legs long; hind femora strongly, middle moderately, front feebly dentate, hind ones distinctly passing apex of elytra. Length, 6 mm. @. Differs in being larger (75 mm.), rostrum longer and thinner, basal punctures and ridges less pronounced, antennz inserted not quite so close to apex of rostrum, basal segment of abdomen more convex and legs somewhat shorter. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1462. The elytral punctures and clothing render this species very distinct. The conspicuous lines of scales are on the third interstice, and about half the length of the prothorax; on the rest of the elytra the clothing is very sparse, and consists of minute sooty scales and some long sooty ones, with a few pale scales congested in places. On the prothorax the scales are stramineous and sooty, and set in punctures. On the under-surface the scales are sparse and thin. The legs are 200 moderately densely clothed, mostly with sooty-brown scales. The very large elytral punctures are often subconical in shape, each narrowed to and open at apex, and cavernous at base, about the base many of them are twice as large as the scutel- lum. The interstices, except on the sides, are not separately convex. On the side-pieces of the mesosternum the punctures are large and distinct, but on the side-pieces of the meta- sternum they are not traceable, being replaced by the narrow and continuous impression. MICROBEROSIRIS. This genus was founded upon a single specimen witl remarkable characters, but the type was somewhat damaged, and, owing to its minute size, it was difficult to manipulate it to see all parts clearly. Its femora, described as without grooves, are really grooved, although these are indistinct from some directions; the funicle is longer than the scape, and its basal joint is as long as the four following ones combined. The rostrum is thin, moderately long in the male, and decidedly long in the female. MICROBEROSIRIS EXILIS, Lea. The type of this species was described as having dense and uniform white scales, but it really has vague remnants of darker markings on the suture, and an angular spot on each elytron about the summit of the posterior declivity. Recently numerous specimens, evidently belonging to the species, were beaten from foliage at Murray Bridge, and these indicate that the species is a variable one, ranging from a form, whose clothing is as on the type, to others with much darker and more extended markings; on many specimens there are two spots on each elytron, and the sutural marking is angularly dilated near the apex; on one specimen the outer - spots are irregularly joined together, so that the elytra appear to be irregularly trivirgate. Many of the specimens have two irregular prothoracic stripes, usually interrupted so as to appear like four angular spots. On the prothorax also some darker scales are scattered singly, giving the surface a speckled appearance. The size ranges from 14 to 12 mm. MICROBEROSIRIS ALBUS, N. sp. 3. Black, in places obscurely diluted with red. Densely clothed with white scales, except on greater portion of rostrum. Rostrum long, thin, and moderately curved; with minute punctures. Prothoraz almost as long as wide, sides lightly rounded, base bisinuate; with dense, concealed punctures. 201 Elytra elliptic-cordate, not much but distinctly wider than prothorax, each separately rounded at base; with rows of rather large partially-concealed punctures in light strie. Pectoral canal terminated at abdomen. JLegs rather short; hind femora not extending to apical segment. Length, 14-12 mm. Q. Differs in having the rostrum slightly longer and thinner and with only the extreme base clothed. Hab.—South Australia (Macleay Museum); Adelaide (H. H. Griffith); Gawler, beaten from foliage (A. M. Lea). Dypet. 17st. A narrow, minute, elliptic species. The clothing is of an almost snowy whiteness, but sometimes with a faint-bluish tinge, and there are no traces of darker markings on any of the twenty-six specimens before me. Parts of the antenne are quite black, and no part is of a distinct red; the apical fourth, or half, of the rostrum is usually of a more or less distinct red. Its tip, when at rest in the canal, appears almost to touch the abdomen, and the tip of the canal does extend to it. AXIONICUS INSIGNIS, Pasc., var. INTERIORIS, n. var. There are six specimens, three of each sex, in the Museum collection that were taken in the Victoria Desert by Mr. Helms during the Elder Expedition, marked as having beep obtained under bark of Kurrajong, and identified, without comment, by the late Rev. T. Blackburn, as Axzionicus msignis. They differ, however, from normal specimens of that species in being decidedly narrower, with somewhat longer legs and with the conspicuous white markings of the normal form either entirely absent, or replaced by stramineous scales and somewhat differently disposed. Thus on all of them the prothorax is without the conspicuous apical patch of the normal form, the postmedian fascia of the elytra is less sharply defined and, although traceable, its presence appears to be marked by sparsity of scales before and after it, rather than to any special character of the scales themselves, as the snowy whiteness of the scales composing the fascia of the normal form. The size varies from 14 to 21 mm. PERISSOPS OCHREONOTATUS, Nl. Sp. ¢. Black, in places sometimes obscurely diluted with red, antennz (club excepted) and tarsi red. With numerous spots of ochreous scales; with minute green scales scattered about. Under-surface and legs with whitish and ochreous scales. 202 Head with small punctures; with a feeble medio-basal line; with a deep fovea extending from eye to eye. Eyes large, facets moderately large. Rostrum rather wide; with an impunctate line along middle, elsewhere with numerous but rather small punctures, concealed on sides of basal half. Scape inserted two-fifths from apex to rostrum, somewhat shorter than funicle. Prothorax moderately transverse ; with small punctures, but with some large ones at the sides in front ; basal half (or two-thirds) with small granules, usually depressed and transverse. Hlytra with outlines almost con- tinuous with those of prothorax, strongly convex; with rows of small punctures, becoming large on sides; with transverse granules or narrow short ridges on three first interstices, and at bases of some of the others. Femora stout, each with a ridge terminating in a distinct tooth; tibie compressed, lightly curved. Length, 6-84 mm. Q. Differs in being less convex, rostrum longer, thinner, with smaller and sparser punctures, and without a smooth median line; scape inserted not quite so close to apex of rostrum, and basal segment of abdomen evenly convex instead of with the intercoxal process shallowly depressed. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1457. A strongly convex, narrowly elliptic species. The rather coarsely faceted eyes, large ocular fovea, and peculiar cephalic clothing are as in semicalvus, with which it would be asso- ciated in my table, but the two species are otherwise very different. The head is bald except for three ochreous spots: one behind each eye and one in middle. On the prothorax there is a stripe (sometimes broken up) on each side, several spots on the flanks, an elongate spot in middle of apex and one on each side of middle. On the elytra the spots are numerous but of irregular size and irregularly distributed. On the under-surface there are fairly numerous spots, in- cluding three on the second abdominal segment. The minute green scales cause the upper-surface to appear opalescent in certain lights. There are some dingy-brown or sooty scales scattered about, but they are very indistinct. On the hind parts of the elytra there are usually feeble rows of whitish scales, but these appear to be very easily abraded, as they are frequently absent, or greatly reduced in numbers. The third interstice at the base is distinctly raised, somewhat curved, and with numerous short transverse ridges. Numerous specimens were obtained at Malanda by beating branches of newly-felled trees. A specimen from Comboyne (New South . Wales) appears to belong to the species, but is too much abraded for certainty. 203 PERISSOPS PARVUS, 0. sp. Of a dingy-red, antennz almost flavous. Densely clothed with soft ochreous or muddy-brown scales, somewhat variegated on upper-surface; under-surface and legs with mostly whitish scales. Head wide; punctures and ocular fovea concealed. LHyes rather small, distant, and coarsely faceted. Rostrum short, wide, and feebly curved; with coarse punctures behind antenne, smooth and almost impunctate in front of same. Scape inserted in middle of rostrum, distinctly shorter than funicle. Prothorax moderately transverse, sides rather strongly rounded, apex more than half the width of base; punctures more or less concealed. Hlytra elongate-subcordate, sides very feebly rounded, and at base but little wider than prothorax; with rows of rather large, but more or less con- cealed, punctures. Mesosternal receptacle moderately wide, with rather thin lightly-elevated walls, not much stouter at base than elsewhere. Abdomen with basal segment rather strongly convex, its apex very feebly incurved to middle. Femora stout, moderately dentate, tibie somewhat com- pressed. Length, 32 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1458. The coarsely faceted and widely separated eyes are at variance with most species of the genus, and the suture be- tween the two basal segments of abdomen is almost straight. But it appears better to refer the species to Perissops rather than to a new genus. It is the smallest species as yet referred to it. On the prothorax there are some sooty scales scattered about, and compacted into two feeble median spots, and two still more feeble apical ones. On the elytra there are a few sooty scales scattered about, and each interstice usually has a row of semi-erect whitish scales. The head is densely clothed. TYRTZOSUS FLAVONOTATUS, Nn. sp. 3. Black, elytra, and rostrum sometimes diluted with red, antenne and tarsi more or less reddish. Rather sparsely (denser and paler on legs than elsewhere) clothed with pale setz or elongate scales, but elytra with numerous small spots of small, wide, flavous scales; a very conspicuous spot on each side of prothorax in front. Head with dense punctures; with a rather feeble median carina, distinctly impressed behind each eye. Eyes rather close together. Rostrum with dense and rather coarse punctures behind antennz, in front of same with smaller and sparser, but more clearly defined, ones. Prothorax with 204 strongly rounded sides; with dense round punctures, larger on sides and smaller about apex than elsewhere, nowhere confluent; median carina strong. Llytra cordate; with rows of large punctures in wide striz, becoming smaller posteriorly, interstices much narrower than striz, each with an irrecular row of small punctures. Jfetasternwm with a conspicuous oblique ridge on each side between coxze; punctures of episterna rather strong but not continuous. Abdomen with a single row of punctures across middle of each of the third and fourth segments; basal segment feebly depressed in middle. Legs stout; femora strongly dentate; hind tibie strongly dilated to apex. Length, 6-74 mm. Q. Differs in being stouter, rostrum somewhat longer and thinner, with smaller punctures, less numerous towards base, antennz inserted not quite so close to apex of rostrum, legs slightly shorter and basal segment of abdomen gently convex. Hab.—Queensland: Cairns district (EK. Allen, F. P. Dodd El) welacker,) A Mi Weal) lvoe ie TaOle An abundant species, close to microthoraz, but elytra more sparsely clothed and cephalic carina more feeble. On microthorax the scales are so dense that the interspaces be- tween the elytral coste are almost entirely covered, and on each elytron there is a conspicuous oblique stripe of pale scales, of which there is no indication whatever on the present species. On that species also the spot on each side of the prothorax is very faintly indicated, and would probably not be noticed unless specially looked for; on the present species, even with badly abraded specimens, the spots are usually very distinct. TYRTZOSUS MAJORINUS, 0. Sp. So. Jet-black, antenne and tarsi reddish. Prothorax with long stramineous sete, nearly all directed towards median carina, each side in front with a conspicuous spot of pale scales. Elytra with sparse, fawn-coloured scales scat- tered about, but with a spot of similar scales behind almost every large puncture, with somewhat larger spots of whitish scales irregularly scattered. Clothing of under-surface vary- ing from white to black. Head with rather dense punctures; with a short distinct medio-frontal carina; with a wide depression behind each eye; these closer together than is usual. Rostrum moderately long; basal half with dense and coarse punctures, somewhat linear in arrangement, apical half with much smaller, but clearly-defined, ones. Prothorax with strongly rounded sides; with large punctures, having a tendency to become 205 longitudinally confluent ; median carina strong. H/ytra slightly wider than in the preceding species, the punctures more dis- tant and shallower, and the striz wider and shallower. Meta- sternum with a strong oblique ridge on each side between coxe, and a distinct subconical tubercle between each ridge and medio-basal impression; punctures of episterna strong but not continuous. Abdomen with a distinct row of punctures across each of the third and fourth segments; first gently concave in middle, second suddenly but not strongly depressed below level of first. Legs stout; femora strongly dentate; hind tibie rather strongly dilated to apex. Length, 84-95 mm. @. Differs from the male, as does the female of the pre- ceding species. Hab.—Queensland: Cairns district (E. Allen, F. P. Pad, A Mo Lea). Type, 1: 1302: The outer walls of the punctures, along the median half of the prothorax, are more or less tilted, so that, from certain directions, the derm there appears to be covered with numer- ous slightly-waved carime. At a glance specimens of this species appear to be simply large ones of the preceding species, but there are seventeen of it before me and forty-eight of the former, and the differences noted are constant. TyRTHZOSUS NIGROMACULATUS, n. sp. 3. Reddish-castaneous, in places more or less deeply stained or spotted with black. Clothed with stramineous ‘scales, some on the prothorax and under-surface almost setose in character, but mostly fairly stout; elytra with wide, depressed scales, more or less congested into feeble spots in the strie. Legs with numerous thin whitish sete. Head with rather dense punctures, becoming coarser in front; a distinct impression behind each eye; these fairly ‘close together in front. Rostrum moderately long, basal half with coarse dense punctures, becoming smaller and more sharply defined in front. Prothorax with strongly rounded ‘sides; with large round punctures, nowhere confluent ; median carina very feeble and scarcely traceable to apex. Slytra with punctures, strie, and interstices much as in flavonotatus. Metasternum with a rather strong oblique ridge on each side between coxe, and with a rather small tubercle between each ridge and medio-basal impression; punctures of episterna not continuous. 4Abdomen with an irregular (semi-double) row of punctures across each of the third and fourth segments, basal segment gently concave. Legs stout; femora strongly ‘dentate; hind tibie strongly dilated to apex. Length, ‘6-8 mm. 206 @. Differs from the male much as in the two preceding species. Hab.—Queensland: Kuranda (G. E. Bryant, H. H. D. Grifith from F. P. Dodd); Cairns (HE. Allen, A. M. Lea). Type, 1. 1303. A rather pretty species, allied to the two preceding ones, but without latero-apical spots of pale scales on prothorax. It is also allied to microthoraz, but is narrower, prothorax considerably larger in proportion, and clothing very different. There are usually at least four distinct dark spots on the elytra (or six counting the shoulders), and these spots are rendered more distinct by their entire absence of clothing; the suture is frequently dark; the prothorax is usually darker than the elytra, but its depth of colour is uniform on the individual; the base and apex of femora and of abdomen are usually darker than the adjacent parts. On some specimens the head appears to have traces of a feeble medio-frontal carina. TYRTZOSUS SUBOPACUS, 0. sp. dg. Of a dingy piceous-brown or black, somewhat diluted with red in places, antennz and tarsi paler. Pro- thorax with fairly stout stramineous setz, on each side in front a feeble spot of stouter and paler scales. Elytra with fairly numerous fawn-coloured scales scattered about, and condensed into numerous small spots, with a few sooty scales in parts. Under-surface with irregularly distributed scales, varying from white to sooty. Legs rather densely clothed, mostly with whitish sete. Head with coarse dense punctures in front; with or with- out a feeble median carina; a distinct depression behind each eye; these moderately close together in front. Rostrum moderately long; basal half with dense coarse punctures, somewhat linear in arrangement, apical half with smaller, but more clearly defined, ones. Club rather elongate. Prothorax with sides strongly and evenly rounded on basal three- fourths, but apex suddenly narrowed; with large round punctures, nowhere confluent; with a strongly raised, narrow, median carina. Hlytra elongate-cordate, not much, but suddenly, wider than prothorax; with rows of large deep punctures in shallow striz, becoming smaller posteriorly ; third and fifth interstices distinctly, the second and seventh less noticeably raised above their fellows, and with transverse squamiferous granules. Metasternum with a strong oblique ridge on each side between coxz, with a very feeble tubercle between each ridge and medio-basal impression; episterna each with a continuous row of strong punctures. Abdomen with basal segment flat and polished in middle, and suddenly 207 and strongly elevated above second; third and fourth each with a single row of punctures across middle. Legs stout; femora strongly dentate; all tibie rather thin, lightly curved, and somewhat narrowed to apex. Length, 54-64 mm. Q. Differs from the male in being somewhat stouter, the rostrum somewhat thinner, longer, shining, and with smaller and sparser punctures, especially towards the base; antennz inserted not quite so close to apex of rostrum; basal segment of abdomen rather strongly convex, not polished, and but feebly elevated above second. Hab.—Queensland: Cairns district (A. M. Lea); Munanda (BH: H. D>» Grifith: from F.:P.:Dodd). .Type, I. 1304. In general appearance fairly close to several species of the genus, but abdomen of the male highly distinctive. The spots of pale scales on the elytra are not confined to the strie, but are frequently continued across several interstices, giving the surface a transversely fasciate appearance. The latero- apical spots on the prothorax are rather feeble, and each is composed of about six scales. The elytra appear to have four dark spots, but these are due more to absence of pale scales than to any other reason. There is a distinct depression behind each eye, narrow and rather deep towards the sides, and dilating towards the middle, so that the whole front of the head is somewhat depressed; this appearance, however, is somewhat obscured by the clothing. Some of the large, subbasal, elytral punctures are supplied with a small granule at the middle of each side. TYRTZOSUS ALTERNATUS, Nn. Sp. Piceous-brown, in places obscurely diluted with red; antenne reddish. Moderately densely clothed with stramineous scales, on the prothorax each scale arising from a puncture; on the elytra somewhat irregularly distributed, and in parts mixed with sooty scales. Head with dense and coarse punctures; a rather narrow depression behind each eye. . Rostrum moderately long, sides regularly incurved to middle; with dense and _ coarse punctures, becoming crowded and irregular towards base, but more or less linear in arrangement; an impunctate median line from near base to near apex. Prothorax with strongly rounded sides; with dense, round, and rather large non- confluent punctures; with a distinct and narrow median carina. Llytra subcordate, base distinctly wider than pro- thorax, basal haif almost parallel-sided; with rows of large .. and somewhat angular punctures, becoming more rounded 208 on sides and smaller posteriorly; interstices as wide as, or wider, than seriate punctures, feebly wrinkled, with small granules, the alternate ones lightly but distinctly elevated, and carinated along middle. J/etasternwm obtusely ridged on each side between coxz; episterna each with a continuous row of punctures. Abdomen with first segment rather short, flat in middle; second not much longer than third, third and fourth rather larger than usual, and each with two distinct rows of punctures across middle. Legs stout; femora strongly grooved and feebly dentate; four front tibiz feebly, the others moderately, dilated at apex. Length, 6 mm. Hab.—Queensland: Mount Tambourine (A. M. Lea). Type, I. 1305. In size and general appearance strikingly close to polluz, but with the third and fifth interstices elevated above the adjacent ones. The teeth of the four front femora are very small and acute, but on the hind pair they are very feeble. TYRTHOSUS PUNCTIROSTRIS, N. Sp. Black, elytra in places diluted with red; antenne and tarsi reddish. Moderately clothed with scales and setz, mostly ashen or ochreous, but in places sooty. Head with large but comparatively shallow punctures in front, becoming smaller posteriorly. Eyes separated almcst the width of rostrum at base; a feeble depression behind each. Rostrum comparatively short and stout, slightly dilated to apex; with dense and coarse punctures of almost even size throughout. Antenne rather short; club large. Prothoraz strongly transverse, sides feebly increasing in width from base to apical third, and then suddenly narrowed; with dense, large, non-confluent punctures; median carina very feeble, and traceable only about middle. /Llytra elongate-cordate, each separately rounded at base, and without subhumeral incision; with rows of large punctures, in rather shallow strie, and becoming smaller posteriorly; interstices much narrower than striz, and each with a row of small punctures. Metasternum with very obtuse ridges cn each side between coxz; episterna each with an interrupted row of sparse punctures. Abdomen with first segment rather short and feebly depressed along middle, third and fourth each with two rows of setiferous punctures. Legs stout; femora rather lightly dentate; hind tibize feebly dilated to apex. Length, 5 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, i306. With an unusually stout and coarsely-punctured rostrum, much as in crassirostris (the punctures are quite as coarse 209 between antenne as at the base), but readily distinguished from that species by the dentate femora. The colour and markings are somewhat suggestive of nigromaculatus, but the rostrum is very different. The type is almost certainly a male, but appears to be somewhat abraded. TYRTZOSUS FOVEIPENNIS, Nl. Sp. g. Jet-black, in parts sometimes diluted with red; antennz and tarsi reddish. Not very densely clothed with scales, more or less ochreous on upper-surface, and paler on under-surface and legs. Head with dense punctures, becoming fairly large in front; a distinct medio-frontal carina; a depression behind each eye, nowhere deep, becoming very shallow towards, and meeting at, carina. Eyes separated the width of rostrum at its extreme base. Rostrum rather long, noticeably dilated in front of antennz, base notched on each side; basal half with dense and coarse punctures, somewhat linear in arrangement, and leaving a narrow median carina, elsewhere with smaller and sharply-defined punctures, sparser between antennz than elsewhere. Prothorax almost as long as wide, sides strongly rounded; with dense, large, round, non-confluent punctures ; median carina strong. /lytra elongate, not much wider than prothorax, each separately rounded at base and without humeral notches, sides feebly rounded (almost parallel) to beyond the middle; with rows of large, deep punctures or fovez on basal half; interstices much narrower than seriate punctures or fovez, each with a row of distinct punctures. Metasternum with a moderate ridge on each side between coxe; episterna each with an interrupted row of large punctures. Addomen with first segment rather small and depressed in middle, third and fourth each with two rows of setiferous punctures across middle. Legs stout; femora rather lightly dentate; hind tibiz moderately dilated to apex. Length, 9-11 mm. Differs in having rostrum slightly longer and thinner, with smaller and sparser punctures, and abdomen with basal segment moderately convex. Hab.—Queensland: Cairns district (A. M. Lea). Type, He L3OT A large elongated species, at first sight apparently be- longing to Mechistocerus, but with very different mesosternal receptacle. On the prothorax the scales form three very feeble longitudinal stripes, and an irregular transverse one (all very indistinct on slight abrasion). On the elytra they are usually condensed into small spots or feeble transverse fascie. The punctures are very large on the basal half (or two-thirds) of 210 ‘the elytra, where each is separated from its fellows by a trans- verse ridge that is almost level with the interstices; so that there the elytra do not appear to be striated, but posteriorly ‘the punctures become much smaller and the striation more evident. The rows of punctures on the interstices cause these, from some directions, to appear as narrow, slightly undulating ridges. TYRTMHOSUS BIVULNERATUS, N. Sp. Black, parts of elytra and of legs obscurely diluted with red, antenne and tarsi reddish. Moderately clothed with reddish-ochreous setz, on the prothorax forming three feeble longitudinal stripes, and on the elytra many compacted into feeble spots. Head with dense and fairly coarse punctures; a curious impression behind each eye. Eyes separated the width of rostrum at extreme base. Rostrum rather long and thin, a distinct notch on each side of base; basal half with fairly coarse punctures, subseriately arranged, elsewhere with smaller but more sharply-defined ones, but almost impunctate along middle. Prothorax moderately transverse, sides strongly rounded, base strongly bisinuate and more than thrice the width of apex; with dense, large, round punctures, in places more or less confluent; with a very strong median carina. Hlytra not much wider than prothorax, sides feebly rounded to beyond the middle, with a very distinct sub- humeral notch on each side of base; punctures and interstices peculiar. J/etasternum with a rather feeble ridge on each side between cox; episterna each with an interrupted row of punctures. Abdomen with first segment scarcely once and one-half the length of second, its apex lightly incurved to middle; third and fourth with comparatively dense setiferous punctures, as on rest of abdomen. Legs stout; femora rather strongly grooved and edentate; all tibiz distinctly dilated to apex, the four hind ones conspicuously bidentate on outer apex. Length, 9 mm. Hab.—Queensland: Mount Tambourine (A. M. Lea). ‘Type, I. 1308. The clothing on the elytra is feebly variegated, but the sete are scarcely stouter than those on the prothorax. The depression behind each eye is deep and sharply defined; it is narrowest at the inner portion of the eye, and dilates out- wardly (instead of inwardly as in other species); in its middle there 1s a narrow shining costa. With the head set out but attached to the body it is more or less concealed. The pro- ‘thoracic punctures, although many are round and isolated, exhibit a tendency to become more or less confluent, especially along the middle, so that, when viewed obliquely, there 211 appear to be numerous feeble ridges extending parallel with the median carina. The elytra at first appear to have very wide striz and narrow interstices, but this is not the case, as the striz are really very narrow (this is very noticeable pos- teriorly) and supplied with irregular punctures; these are rather large on the basal half, and each appears to be supplied with granules that really belong to the interstices. The inter- stices are much wider than the strie, and each, except the suture, is more or less distinctly ridged along the middle, and with a conspicuous row of punctures on each side of the ridge. The dentition of the four hind tibie is suggestive of Psepholacipus. TYRTHOSUS BIFOVEICEPS, Nl. sp. Black; antenne and tarsi reddish. Head with coarse and somewhat irregular punctures in front; a rather deep and somewhat pyriform impression behind each eye. Eyes separated the width of rostrum at extreme base. Rostrum rather long and thin, notched on each side of base; basal half with rather coarse punctures, subseriately arranged, and leaving a median carina, which is distinct only at extreme base, apical half with small punctures, but absent along middle. Prothorax and elytra with outlines much as in preceding species; metasternum, abdomen, and femora much the same. All tibize dilated to apex, the four hind ones not bidentate at outer apex. Length, 9 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, be. £309) The types of this and the preceding species are uniques; their shape and general appearance are much the same, and the sculpture of the present species might be regarded as. simply an exaggeration of that of the preceding; but the four hind tibiz are so different, :nter se, that I have not hesitated to describe them as distinct. The depression behind each eye is much as in the preceding species, but is rather less sharply defined; the one behind the right eye is somewhat obscured by an oblique (but not shining) ridge, but the other is simple. The type is certainly somewhat abraded, but the clothing that is left consists of more or less ochreous sete#, and was apparently very similar to that of the preceding species. The prothoracic punctures are rather larger than in that species, and with a less tendency to become confluent. The elytra about the basal half appear to have striz much wider than the interstices, owing to the punctures there (although large) not being sharply defined, but on the apical half of the elytra the striation is deep, narrow, and sharply defined, the inter- stices much wider than the striz, and, except the suture, each 212 ridged along middle. The type of the present species is probably a male, as the basal segment of its abdomen is dis- tinctly depressed in the middle; in the type of the preceding species it 1s gently convex. TYRTOSUS SQUAMICEPS, Nn. sp. Of a dingy reddish-brown, antennez and tarsi paler, elytra in parts stained with black. Moderately clothed with fawn- coloured or pale-ochreous scales, on the prothorax forming three feeble longitudinal stripes (the interspaces mostly with sooty scales) and on the elytra usually compacted into many feeble spots, on the head (except between eyes) denser than elsewhere. Head with dense punctures, normally concealed by clothing. Eyes separated the width of rostrum at extreme base. Rostrum not very long and rather wide, sides lightly incurved to middle, with rather coarse and dense punctures about base, but small elsewhere. Prothoraxz almost twice as wide as long, sides strongly rounded, apex about half the width of base; punctures not very large, shallow, and more or less concealed; without median carina. SHlytra very little wider than prothorax, subhumeral notches distinct, sides lightly rounded; striation deep and narrow, with more or less concealed punctures; interstices flattened, about twice the width of striz, and with more or less concealed punctures and granules. Mesosternal receptacle shorter and less elevated than usual. Metasternum scarcely ridged on each side be- tween coxe; episterna each with a somewhat irregular row of punctures. Abdomen with first segment slightly flattened in middle, apex lightly incurved to middle; third and fourth each with a row of strong punctures across middle. Legs moderately stout; femora feebly grooved and feebly dentate ; tibie rather thin, all slightly narrowed to apex. Length, 34-4 mm. Q. Differs in having the rostrum somewhat thinner, sides less noticeably incurved to middle and with sparser punctures, and abdomen with basal segment moderately convex. Hab.—North Queensland (Blackburn’s collection) ; Cairns district (A. M. Lea). Type, I. 1310. In general appearance close to castor, but with femoral teeth much smaller and elytra without two distinct white spots. Each elytron appears to have a large dark medio-lateral space, due partly to being there stained with black, and partly to its clothing being sparse and mostly sooty. The depression behind each eye is extremely feeble, and might fairly be regarded as absent. 213 TYRTZOSUS CONCINNUS, DN. sp. Velvety-black, in places obscurely diluted with red; antennz and tarsi reddish. With rather dense, fawn-coloured scales, on the prothorax forming three distinct longitudinal lines, and on the elytra closely compacted into numerous small spots; prothorax between the stripes and elytral interstices with longer and usually paler scales. Head and legs densely, the under-surface rather sparsely, clothed. Head with dense but more or less concealed punctures. Eyes widely separated, no depression behind them. Rostrum moderately long, sides distinctly increasing in width towards, but notched at, base; basal third with rather coarse and somewhat crowded punctures, elsewhere with sparse and more or less minute punctures, but absent from middle. Prothorax strongly transverse; median carina absent. JLlytra_ sub- cordate, not much wider than prothorax, with rows of large, deep punctures, becoming much smaller posteriorly; inter- stices on basal half much narrower than striz, but becoming wider and flatter till on the posterior declivity they become distinctly wider than the strie. Mesosternal receptacle and abdomen as in preceding species. Metasternum not ridged ‘on each side between coxe ; episterna each with an interrupted row of punctures. Legs moderately long; femora rather feebly grooved and lightly dentate; tibie all somewhat nar- rowed to apex. Length, 53 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, te, ded. A rather pretty little species; at first appearing like a large specimen of the preceding one; but clothing denser (notably on the legs), elytral interstices narrower, and antennal insertion not quite the same. The clothing if at all constant (it is evidently in perfect condition on the type) should render the species every distinct. To the naked eye the prothorax appears to have a dark spot on each side of the base, the derm there being glabrous; on the elytra the fawn-coloured scales form numerous small spots, and one larger one on the middle of each; each of the larger ones is rendered more conspicuous by a small spot of sooty scales before and one after it; there is also a similar sooty spot common to the second and third interstices at about one-fifth from the apex. The prothoracic punctures are so placed that each appears to be bounded behind by a transverse or semi- circular granule, these being very conspicuous from in front. TYRTHZOSUS BREVIROSTRIS, Nn. sp. 3. Black, sometimes obscurely diluted with red; antenne and tarsi reddish. Rather densely clothed with stout 214 fawn-coloured and sooty scales, the sooty ones very sparse om under-surface. Head with coarse more or less concealed punctures. Hyes widely separated, a narrow normally-concealed depression behind each. Rostrum rather short, wide, and almost straight; with dense and coarse punctures, but on basal third concealed. Prothorax almost as long as wide, sides strongly rounded; with dense, round, deep, non-confluent punctures ; median carina scarcely, or not at all, traceable. SHlytra parallel-sided to near apex, not much wider than prothorax, subhumeral notches almost absent; with rows of large, deep punctures; interstices in places wider, in places narrower, than punctures, with sparse granules, but surface more or less concealed by clothing. Mesosternal receptacle larger and more elevated than usual. Metasternum with a conspicuous. ridge on each side between coxe; episterna each with a con- tinuous row of punctures. Abdomen with basal segment not as long as second and third combined, depressed in middle, apex lightly incurved to middle; third and fourth each with two rows of squamiferous punctures. Legs stout; femora strongly dentate; hind tibiz lightly dilated to apex. Length, 4-43 mm. Q. Differs in having the rostrum slightly thinner, shining, and with concealed punctures only at extreme base, the punctures elsewhere small but clearly defined; antennz inserted just perceptibly nearer base than apex of rostrum (instead of in the exact middle), and basal segment of abdomen moderately convex. Hab.—Queensland: Cairns district (F. P. Dodd and A. M. Lea); Little Mulgrave River (H. Hacker). Type, Pears. The mesosternal receptacle is unusually stout, and the rostrum unusually short for the genus. It is a subcylindrical species, with clothing so dense as to greatly obscure the derm of the elytra. The sooty scales are distributed in small patches on the upper-surface, causing this, to the naked eye, to appear speckled; the interstices each have a row of stout scales, but as these are similar in colour to the surrounding ones they are but little evident; each elytral puncture is also supplied with a scale. The junction of the fourth and fifth interstices on the posterior declivity is marked by a small spot, con- spicuous to the naked eye, of pale scales, encircled by dark ones, and is alike on all six specimens under examination. The punctures of the under-surface are larger and denser than usual. 215 TyRT#OSUS APICICOLLIS, n. sp. Reddish-brown, in parts obscurely stained with darker brown. Moderately clothed with fawn-coloured scales. Head with numerous, but not crowded, punctures of moderate size; a rather narrow depression behind each eye. Eyes separated the width of extreme base of rostrum. Rostrum moderately long, thin, and parallel-sided, notched on each side of base; basal half with coarse crowded punctures, apical half with much smaller, but sharply defined, ones. Prothorax moderately transverse; with dense, large, round, non-confluent punctures; median carina very feeble, and not traceable to base or apex; near apex deeply trans- versely impressed across middle. lytra about one-fourth wider than prothorax, sides parallel to beyond the middle, subhumeral sinus scarcely traceable; with rows of large, but partially concealed, punctures; interstices much wider than punctures, each with a partially concealed median row of granules. Metasternum without a conspicuous ridge on each side between coxz; punctures of episterna interrupted. Abdomen rather large, first segment not as long as second and third combined, second much shorter than third and fourth combined; these each with two irregular rows of squamiferous punctures across middle. Legs comparatively thin; femora feebly dentate; tibiz not dilated to apex. ‘Length, 5 mm. Hab.—Australia (Blackburn’s collection). Type, I. 1313. The apex of the prothorax is conspicuously elevated in front, owing to the deep subapical impression. The clothing on the upper-surface on the type is not variegated, but, as it is not uniformly distributed, the surface appears somewhat speckled. The head and exposed parts of the body have a _bluish iridescence, but it is very faint and could easily be ‘overlooked. TYRTHOSUS MODICUS, Nn. sp. Piceous-brown, in parts obscurely diluted with red; antenne and tarsi of a dingy-red. Prothorax with a dingy scale in each puncture, not, or scarcely, rising to general level, but with a feeble median line of longer and paler scales, and remnants of a line on each side. LElytra with rather dense -and somewhat ochreous scales, with irregular spots or patches of sooty ones. Under-surface and legs with pale scales, sparser on abdomen than elsewhere. Head with dense and rather coarse punctures. Eyes separated the width of extreme base of rostrum, a narrow depression behind each. Rostrum not very long, fairly stout, almost parallel-sided; basal half with coarse partially- concealed punctures, apical half with smaller (but not very 216 small) sharply-defined ones. Prothorax moderately trans- verse, sides strongly rounded; with dense, large, round, non- confluent punctures; median carina not very strong, but trace- able from base to apex. Elytra about one-third wider than prothorax, sides parallel to near apex, subhumeral sinus scarcely traceable; with rows of large, deep punctures, becom- ing smaller posteriorly. Jetasternum without an elevated ridge on each side between coxze; punctures of episterna interrupted. Abdomen with second segment almost as long as third and fourth combined; these each with one row of punctures across middle. Legs not very stout; femora rather strongly grooved and feebly dentate, hind tibie slightly dilated at apex. Length, 4% mm. Hab.—Queensland: Mount Tambourine (A. M. Lea). Type; is 1314. On the elytra there appear to be several irregular dark patches, due partly to patches of sooty scales, and partly to absence of paler ones. The scales more or less obscure the sculpture, but the interstices are mostly wider than the seriate punctures, and each appears to be supplied with a median row of granules. A second specimen from Mount Tambourine differs in being smaller (44 mm.), the scales on the elytra mostly sooty, the ochreous ones being distributed in irregular transverse spots or fasciz, and a row of small granules on each interstice is seen where the derm has been abraded. The punctures on its head are somewhat smaller than on the type; its abdomen is flattened in the middle of the first segment, and on the type that segment is uniformly convex, but this difference is probably sexual. TYRTHOSUS FOVEIVENTRIS, 0. sp. Black or blackish, antennz and tarsi reddish. Densely clothed with sooty scales, interspersed with white ones. Head with dense but more or less concealed punctures. Eyes separated almost the exact width of extreme base of rostrum, a narrow but partially-concealed impression behind each. Rostrum moderately long; basal third with coarse, partially-concealed punctures, elsewhere with rather small but clearly-defined ones. Prothorax small, about as long as wide, sides strongly rounded; with large round punctures, very close together, but nowhere confluent; median carina rather feeble but traceable from base to apex. Hlytra about one- third wider than prothorax, base lightly trisinuate, sides parallel to beyond the middle; punctures and interstices partially concealed. Metasternum with the dividing lines between the median and lateral portions very distinct, but not marked by elevated ridges; punctures of episterna 217 interrupted. Abdomen with basal segment depressed along middle, second about once and one-third the length of third or fourth, these each with two rows of squamiferous punctures across middle; apical segment with a large shallow fovea. Legs moderately stout; femora rather strongly grooved, the front ones moderately, the others lightly, dentate; hind tibie moderately dilated at apex, the front ones lightly, the middle ones not at all. Length, 64-7 mm. Hab.—New South Wales: Blue Mountains (Blackburn’s collection); Victoria (H. W. Davey). Type, I. 1315. In general appearance close to pollux, but prothoracic carina shorter and less distinct; elytra more roughly sculp- tured and with narrower interstices, and metasternal episterna with punctures not continuous. Also close to eimerascens, but interstices not carinated towards base, and the space there flattened and irregularly punctate and squamose; this will also distinguish it from pardalis. The white scales are irregularly distributed in small spots on the elytra, causing these to appear speckled; on the prothorax there are three vague lines of pale scales (individually longer than those on elytra), but most of the scales are sooty and do not rise above their containing punctures. On the under-surface, and on the under-parts of the legs, the scales are mostly grey or of a dingy-white. The elytral punctures are fairly large, and appear to be more or less angular or quadrate, but the cloth- ing is so distributed that few can be seen clearly; the inter- stices are usually wider than the punctures, and, where inten- tionally abraded, are seen to be covered with short transverse ridges or granules, so that the whole elytra have a peculiarly rough appearance; although their punctures (in comparison with those of many others of the genus) are not particularly large. The (three) specimens under examination appear to be all males. TYRTZOSUS BASIVENTRIS, N. sp. ~ ¢. Piceous; elytra red, in places deeply and irregu- larly stained with black; antenne and tarsi reddish. Elytra with somewhat ochreous scales congested into feeble spots; prothorax feebly clothed. Legs with thin, whitish scales or sete. Head with rather small and sparse punctures; inter- ocular fovea rather large. Eyes separated the width of extreme base of rostrum; a deep angular impression behind each. Rostrum moderately long, distinctly notched on each side of base; basal third with coarse crowded punctures, else- where with small but usually clearly-defined ones. Prothoraz strongly transverse, sides strongly rounded: with dense, large, round, non-confluent punctures; median carina very feeble, 218 but traceable throughout. Slytra with base strongly trisinuate, closely applied to and scarcely wider than pro- thorax; sides almost parallel to beyond the middle; with rows of rather large and somewhat distant punctures, in dis- tinct striz; interstices much wider than seriate punctures, ridged along middle, with a mo.e or less obscure row of punctures on each side of each ridge. MAfetasternum very feebly ridged on each side between coxze; punctures of episterna interrupted. Abdomen with basal segment dis- tinctly produced in middle of apex, so that there its length is almost equal to that of the three following combined, narrowly depressed along middle, each side of depression marked by a row of sparse but very distinct scales, becoming: rather numerous at apex; second segment along middle very little longer than third or fourth, each of these with a con- spicuous row of punctures across middle. Legs rather thin; femora moderately grooved and lightly dentate; hind tibie: very feebly dilated at apex. Length, 4 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, WATSTG: Readily distinguished from all previously deseribed species by the abdomen of the male. At a glance the type is extremely like some of the small variegated species of Melanterius, and in fact, without examination of the meso- sternal receptacle, it is quite impossible to decide as to whether many species belong to T'yrtcosus or to Melanterwws. The derm, where not concealed by scales, appears to have a bluish iridescence, this being specially noticeable on the abdomen and on the dark parts of the elytra. The elytra are rather pretty owing to the spotting of the ochreous scales on the red derm and the many blue-black patches. On the prothorax the scales seldom rise to the general level. The depression behind each eye appears to be in the form of a triangle from certain directions. Two, near the base three, of the lateral interstices: are highly polished, but this is a fairly common feature in the genus, and the amount of polish is probably due, to a certain extent, to rubbing by the femora. Two specimens (from Kuranda) appear to be females, they differ from the type in being smaller (3 mm.), with the basal segment of abdomen gently convex in middle, without longitudinal rows of scales, and the apex very feebly produced, so that, along middle, its length is only about equal to that of the third and fourth combined, and the second is con- spicuously longer than the third or fourth. The rostrum is: thinner, with smaller and sparser punctures, and the elytra are conspicuously wider than the prothorax, with the base less: noticeably trisinuate. 219 TYRTHOSUS TRILINEALBUS, D. sp. Black, with a slight bluish gloss. With rather sparse and irregularly distributed sooty scales; but prothorax with three conspicuous lines of white scales; a short oblique line of white ‘scales on each elytron close to scutellum, and similar scales on suture on the posterior declivity. Legs with whitish and sooty setz. Head with small partially-concealed punctures. Eyes with rather smaller facets than usual, separated less than width of rostrum at base. Rostrum not very long, sides distinctly in- curved to middle ; with rather small clearly-defined punctures, becoming larger and partially concealed about base. Antenne inserted almost in exact middle of rostrum ; club rather large. Prothoraz rather strongly transverse, apex more than half the width of base ; with moderately large, round, deep, sharply-cut punctures, becoming very small and sparse at apex: without median carina. Hlytra cordate, each separately rounded at base, and without subhumeral incurvature, sides evenly rounded ; with rows of rather narrow, suboblong punctures, in narrow, shallow strize; interstices flat, wider than striz, the second widest of all. Metasternum about two-thirds the length of the following segment ; without an elevated ridge on each side between coxz; punctures of episterna almost con- tinuous. Abdomen with first segment slightly longer than second and third combined, gently convex in middle, second subequal to third and fourth combined ; each of these with a row of punctures across middle. Legs moderately long ; femoral teeth acute but rather small; all tibiz parallel-sided, except at ends, and not dilated at apex. Length, 3 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, ad. 13h7. Referred to Tyrtwosus with hesitation on account of the base of the elytra and rather finely faceted eyes. At first ‘sight it appears to belong to Gymnoporopterus, but the meta- sternum is rather long, with conspicuous episterna. The meso- sternal receptacle has rather thinner walls and the basal por- tion smaller than usual, but the emargination is rather widely U-shaped ; from some directions it appears to be open, but as its wall at the base is directed slightly forwards, it must be regarded as cavernous. The tarsi and antennz are almost as black as the other parts. The type, judged by the abdomen, appears to be a female. TYRTZOSUS ABERRANS, DN. sp. Black, antennz and tarsi of a rather dingy-red. Moder- ately clothed with sooty scales, with many feeble spots of ‘stramineous or whitish ones. Legs and under-surface with whitish sete. 220 Head with crowded, somewhat indistinct punctures. Eyes rather larger and with somewhat smaller facets than usual ; separated about half the width of base of rostrum. Rostrum rather short and wide; basal third with coarse partially- concealed punctures, elsewhere with smaller but clearly-defined ones. Antenne rather short; scape inserted somewhat nearer base than apex of rostrum, and scarcely half the length of funicle and club combined. Prothorax rather strongly trans- verse, basal half almost parallel-sided, punctures much as on preceding species; median carina absent. /lytra parallel-sided to near apex, base rather lightly trisinuate, and not much wider than prothorax; with rows of suboblong punctures in rather feeble striz; interstices feebly separately convex, distinctly wider than seriate punctures. dfetasternum with a rather feeble ridge on each side between cox; punctures of episterna feeble, but apparently not interrupted. Abdomen with first segment feebly depressed in middle, apex very feebly incurved to middle, as long as second and third combined; second slightly longer than third and fourth combined; each of these with a very feeble row of punctures across middle. Legs stout; femora rather strongly dentate; tibize not dilated at apex, somewhat angular near outer base, but not dentate. Length, 2} mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, i. 1318. Another minute aberrant species of the genus, but not sufficiently so to be regarded as generically distinct. The meso- sternal receptacle, hcwever, is normal. The clothing to a cer- tain extent obscures the punctures and interstices of the elytra, but where visible the interstices do not appear to be in any way roughly sculptured. As the Australian species of this genus have now been almost doubled since my first table of the species, and the genus is a rather difficult one, a second and enlarged table is here given. A character which at first would appear to be of con- siderable use in subdividing it is the median prothoracic carina; in many species it is strong and continuous, and in others entirely absent ; but as there are several species in which it is so feeble that it might be regarded as absent, and others in which it varies to a certain extent individually, it has not been used.

Some of the other interstices have this peculiar appear- ance, but it is more conspicuous on the ones mentioned. i. The sides of the segments are usually densely, or at least irregularly, punctured. q. On densely squamose species, such as laterarius, this ‘character is not at once apparent, but on looking at the elytra from behind, the rows of larger scales are quite distinct. DD. This character is not always to be relied upon, but it is a very useful feature, and notes are given on the species in which it is known to vary. The episternum shortly before its front triangular extension is narrowed and punctures are absent from the narrowest portion. In the other species, although the punctures are frequently denser at the ends, at least one row is traceable at the narrow part. E. On bifasciatus the punctures are in irregular semi-double rows for the greater portion of these segments, but on the median fifth they sometimes appear to be in single rows. G. The punctures on the basal half of the elytra are always large, but on melanterioides they are quite unusually so. _ _H. This is more conspicuous on the male than on the female; it has nothing to do with the acute ridge between the coxe, the apex of which from some directions may appear to be tuberculate. ‘On foveipennis a vague remnant of it is traceable. JJ. On the majority of species of the genus there is a strong oblique ridge on each side of the metasternum between the coxe. It was not found advisable, however, to use the character as a main feature of the table, as the gradations between acutely elevated and absent are numerous. When the metasternum is examined from the side, there is a line whence the surface appears to slope down to the margin on one side, and on the other to the middle, and this line may appear to be somewhat like a ridge, but the ridges referred to in the table are distinct and rather narrow elevations above the surface. 225 TYRTAOSELLUS, 0. g. Head fairly large, partially concealed from above. Eyes large, widely separated, coarsely faceted. Rostrum more or less parallel-sided, moderately long and curved. Antenne rather thin, inserted nearer apex than base of rostrum; scape the length of funicle; funicle with first joint stouter and longer than second, second longer than third; club ovate. Prothoraz as long as wide, or feebly transverse, sides rounded, base bisinuate. Scwtellum distinct. EHlytra narrow, but dis- tinctly wider than prothorax, usually parallel-sided to beyond the middle. Pectoral canal deep, terminated between four front coxz. Mesosternal receptacle widely U-shaped, cavern- ous. Metasternum rather long, but shorter than following segment; episterna distinct. Abdomen rather long, two basal segments large, suture between them straight; three apical segments depressed below the others; third and fourth con- joined slightly longer than second or fifth. Legs long and thin; femora feebly grooved, dentate or not, posterior ex- tending, or almost extending, to apex of elytra; tibiz thin, feebly diminishing in width to apex. Elongate, strongly convex, squamose, fasciculate or not. In my table of genera allied to Crytorhynchus ©) would be placed in I. Of the genera placed there in appearance they are nearest to Pezichus, but the hind femora do not pass the elytra (in coxalis and nigrofasciatus they extend to the apex, in attenuatus and alternatus almost to the apex). The rostrum although fairly long in the females is shorter than in Pezichus. The species are all very small in comparison with those of that genus. In the table referred to, under w, two genera are placed as having edentate femora, and four as having dentate femora. I believe the four species referred to the present genus are truly congeneric, despite the facts that two have dentate, and two edentate, femora. The species with edentate femora differ from those referred to & in the table, Quweenslandica (now Orochlesis) and Sclero- poides, in the narrower and more convex body, longer legs and much narrower tibie; from those referred to kk the straight suture between the two basal segments of abdomen associates them with T'yrtwosus. The only valid distinguish- ing feature that I can find between these species and Tyrteosus lies in the tibiz. In these species the tibie are long, thin, and gradually decrease in width from near the base to the apex, or at any rate the hind pair so decrease. In Tyrteosus the tibie are either of even width throughout, or they dilate in width to the apex, the hind pair usually (5) Proc. Linn. Soc. N.S. Wales 1907, pp. 401-403. I 226 being conspicuously wider at apex than elsewhere. This dif- ference appears very slight to found a genus upon; neyer- theless the four species are so obviously closely related, and. in facies and clothing certainly different, to Tyrtcosus, that it does not appear to be desirable to refer them to that genus. The second abdominal segment slopes down at an angle of 45°; in most species of 7'yrtwosus the descent is more gradual ;. the species of that genus usually also have decidedly shorter legs.

TYRTHOSELLUS ATTENUATUS, 0. sp. Blackish, in parts obscurely diluted with red; antenne and tarsi reddish. Rather densely clothed with dingy-greyish scales, somewhat variegated with paler and darker ones; with numerous stout, semi-upright ones interspersed.

Type, {. 1479. The elytral attenuation commences nearer to the base than in other species of the genus. Parts of the elytra appear to be obscurely diluted with red, especially where the scales are paler than elsewhere. The type (whose sex is doubtful) is unique, but its shape should be distinctive. The clothing may not be constant; on each elytron there appears to be a vague triangle of sooty-brown scales extending from the side (from near the base to beyond the middle) to the third interstice slightly beyond the middle, behind this triangle the scales are paler than elsewhere, so that a wide sutural space on the posterior declivity is clothed with scales that appear almost white to the naked eye. SOPHRONOCIS, n. g. Head rather large. Eyes moderately large, coarsely faceted. Rostrum short, wide, and almost straight. Antennz moderately stout, inserted about middle of rostrum; scape distinctly shorter than funicle; two basal joints of funicle elongate, the others very short; club ovate.

Pectoral canal deep and wide, terminated just behind front coxz. Mesosternal receptacle rather strongly raised, emargination semicircular ; cavernous. Metasternum about the length of the following segment; episterna distinct. Abdomen with first segment as long as second and third combined, its apex lightly incurved to middle, second as long as third and fourth combined. Legs rather long and thin; femora neither grooved nor dentate, hind pair not extending to apex of abdomen; tibie lightly compressed. Close to Tyrteosus, but suture between first and second segments of abdomen not quite straight, and the femora edentate. In the table of genera allied to Cryptorhynchus ‘6 would be associated with Scleropoides, from which it differs in the much shorter rostrum and scape, and non-grooved femora. SOPHRONOCIS ALBONOTATUS, Nn. Sp. Black, in places feebly diluted with red; antenne and tarsi red. Moderately clothed with black suberect scales, variegated with small spots of whitish ones. Head with dense punctures, of moderate size between eyes, smaller elsewhere; ocular fovea fairly large. Rostrum (6) Proc. Linn. Soc. N.S.

Hlytra almost thrice the length of prothorax and about one-fourth wider, base trisinuate, median sinus more pronounced than the others; with rows of large, partially-concealed punctures; interstices narrower than punctures, except posteriorly. Under-surface with somewhat irregularly distributed punctures, larger on basal segment of abdomen than elsewhere. Length, 3 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, Petats. On the type, whose sex is doubtful, there are eight whitish spots on the prothorax: four across middle, three near apex, and an elongated medio-basal one. On each elytron there is a small median and two subapical spots, but a few white scales are scattered singly elsewhere. On the under- surface the scales are sparse and mostly whitish. There are three feeble whitish spots on the head. LEUCOTHYREOCIS, n. g. Head fairly large, but almost concealed from above. Kyes rather small, widely separated, coarsely faceted. Rostrum of moderate length and width, distinctly curved. Antenne moderately thin; scape inserted nearer apex than base of rostrum and shorter than funicle; two basal joints of funicle elongate; club ovate. Prothorax lightly transverse, base bisinuate, sides rounded, apex produced. Scutellum dis- tinct. Hlytra strongly convex, narrowly cordate, each separately rounded at base. Pectoral canal deep and wide, terminated between middle coxze. Mesosternal receptacle scarcely elevated above coxz, base rather large, emargination widely transverse; cavernous. Metasternum long; episterna distinct. Abdomen large, sutures straight, first segment as long as second and third combined, second as long as third and fourth combined. Legs rather short; femora strongly grooved and edentate; tibize almost straight. | Rather close to Tyriewosus, but femora edentate and strongly grooved.

It also resembles some of the densely-clothed species of Ampagia, but the abdomen and femora are normal. The metasternum and basal segment of abdomen at first appear to be of the same length, but in the exact middle the metasternum is a trifle shorter. LEUCOTHYREOCIS CONVEXUS, 0. sp. d. Of a dingy reddish-brown, parts of under-surface almost black. Densely clothed with light-brown or fawn- coloured scales, variegated in places with paler and darker ones, but on scutellum conspicuously white. With numerous stout, erect scales interspersed. Head with dense, concealed punctures. Rostrum almost the length of prothorax, sides gently incurved to middle; basal two-thirds with coarse partially-concealed punctures, elsewhere with smaller, clearly-defined ones.

Type, T1538: On the prothorax the erect scales are more numerous across the middle and at apex than elsewhere, but they do not form fascicles. On each elytron, however, there is a dis- tinct black fascicle on the third interstice about the middle. On two specimens there are fairly distinct and rather numerous pale spots on the elytra, but on another almost all the depressed scales, on the upper-surface, are more or less of a dingy-grey. Gyeaus. (8) The original diagnosis of this genus simply pointed out two characters of the abdomen in which it differed from Tyrteosus. As at least two species occur in Queensland, some additional particulars may be given. (8) Pascoe, Ann. Mus. Civ. Gen. 1885, p. 273. 231 Forehead somewhat sinuous. Eyes rather coarsely faceted. Elytra much wider than prothorax, base trisinuate. -Mesosternal receptacle somewhat depressed in front, walls rather thin and U-shaped; cavernous. Metasternum some- what shorter than the following segment; episterna wide. Legs moderately long; femora obtusely dentate. Body winged. GYGHUS PRODIGUS, Pasc.(9) I am indebted to Dr. Gestro for a Fly River co-type of this species. It, and four specimens from the Coen River (North Queensland), all have the rostrum black, whereas the type was described as having it castaneous, but this may have been due to immaturity or to individual variation. The sulcus at its apical sides is simply a feeble continuation of the scrobe. The second joint of the funicle is distinctly longer than the first. On the prothorax there is a feeble median carina, which at the base appears as a scutellar lobe, and at the apex as a fasciculated crest. On each side of the suture, near the base, there are some small, shining granules, varying in number from three to six. GYGHUS SQUAMIVENTRIS, 0. sp. 36. Black; antennze and tarsi more or less reddish. Densely clothed with rusty-brown or light-brown scales, more or less conspicuously variegated with greyish or stramineous ones; elytra in places with sooty scales. With numerous stout, suberect scales scattered about, and on swellings con- densed into fascicles. Abdomen with sooty scales, except at base and sides. Head with concealed punctures; forehead lightly sinuous. Rostrum long and rather thin, sides lightly incurved to middle; apical third with dense and not very small punctures, elsewhere punctures concealed, but with a distinct median carina. Scape inserted about two-fifths from apex of rostrum, the length of funicle; first joint of funicle slightly shorter than second; club elongate, sutures oblique. Pro- thorax moderately transverse, sides strongly rounded; with a short median carina; with feeble swellings, supporting four distinct fascicles across middle, and two at apex; with large, dense, concealed punctures. Scutellwm moderately large. Elytra about once and one-half as wide as long, distinctly wider than prothorax; with rows of large, partially-concealed punctures; suture with numerous shining granules on basal half and with a distinct fascicle crowning the posterior declivity ; third interstice with a distinct fascicle near middle, ihc ply BS: 232 and a larger one, mixed with granules, near base; fifth with two rather small fascicles. Jemora rather lightly dentate. Length, 94-11 mm. @. Differs in having the rostrum distinctly thinner, punctures concealed only on basal third, elsewhere polished, and with minute punctures. Scape inserted slightly nearer the middle of rostrum, and abdomen a trifle more convex. Hab.—Queensland: Cairns (E. Allen, J. A. Anderson, F. P. Dodd, H. Hacker, and A. M. Lea). Type, I. 1540. Readily distinguished from prodigus by the prothorax being bifasciculate in front instead of crested. The upper- surface is much like that of many species of Desmidophorus. The fascicles and the paler scales give the upper-surface a somewhat mottled appearance. The patch of sooty scales on the abdomen covers most of its surface. On the flanks of prothorax there is a vague, sooty stripe, obliquely continued on to each shoulder; and near apex of elytra there is a narrow, transverse stripe of similar scales. On old or dirty specimens, however, the clothing of the upper-surface appears to be of a more or less uniform muddy-brown. The sinuation of the forehead is traceable, although partially masked by scales. CRYPTORHYNCHUS APICIPENNIS, ll. sp. Black; antenne and parts of tarsi reddish. Apex of prothorax and posterior declivity of elytra with dense stramineous scales, fasciculate in places; rest of upper-surface glabrous, or sparsely and indistinctly clothed. Under- surface with sparse, sooty scales, and a few stramineous spots. Legs rather sparsely clothed. Head with dense punctures and an obtuse median ridge. Rostrum rather long; with crowded and rather coarse punctures, becoming smaller in front; with a rather feeble median ridge. Prothorax moderately transverse, sides strongly rounded; with a continuous median carina, narrow at each end, and thickened in middle; with numerous large granules, each with a frontal puncture. Scutellwm round, very distinct, and within a depression. JElytra elongate- cordate, about one-third wider than prothorax; with semi- double rows of very large punctures or fover, becoming small posteriorly; with a few irregularly distributed granules. Legs long; femora rather lightly dentate. Length, 10 mm. Hab.—Victoria (Blackburn’s collection from C. French). wlype, . lo21. The sculpture is unusually coarse, on part of the elytra being suggestive of that of Melanterius semiporcatus, and this, with the curious clothing, render the species very distinct. 233 The patch on the elytra is widest near its summit, then nar- rowed to about halfway to the apex, and then almost parallel- sided to the apex itself. The mesosternal receptacle is pecu- liar, it slopes gently upwards from base to apex, with the walls in front abruptly vertical to near the bottom, but there each is directed forwards, like a short wedge. But it is probable that these wedge-like processes are concealed by the front coxz, on specimens with the prosternum closely applied to the mesosternum. Very faint approaches to a similar structure may be seen in pretzfrons and verus. BoTHYNACRUM OCHREONOTATUM, Lea, var. A female, from Cairns, evidently belongs to this species, but differs from the type female in having no white post- median patch on the elytra, the same being replaced by con- spicuous ochreous spots, similar to the others on the upper- surface. PEZICHUS DECIPIENS, 0. sp. o. Black, antennze and tarsi more or less reddish. Moderately, but somewhat irregularly, clothed with rusty- brown scales, in places compacted into feeble fascicles; elytra with several small, transverse spots of white scales. Head small; with dense and rather shallow punctures ; a narrow impression behind each eye, and with a feeble medio- frontal ridge. Rostrum long, thin, and rather lightly curved, sides slightly dilated to base; apex with small and rather dense punctures, becoming larger towards and rather coarse at base. Antenne thin; scape inserted about one-fourth from apex of rostrum, about as long as funicle and club com- bined; second joint of funicle slightly longer than first. Prothoraz slightly longer than wide, sides strongly rounded ; with large round granules, or small tubercles; with a very conspicuous carina, on apical three-fourths. Scutellum round and distinct. Hlytra much wider than prothorax, parallel- sided.to beyond the middle; with rows of large and rather distant punctures, becoming very small posteriorly; third and fifth interstices somewhat elevated, except posteriorly. Apical segment of abdomen widely excavated and notched at tip. Legs long; femora moderately dentate, hind pair passing tip of elytra. Length, 12-134 mm. Q. Differs in having the apical segment of abdomen evenly rounded at apex, and not excavated in middle. Hab.—Queensland: Cairns district (F. P. Dodd and mM. ea). Type,,1. 1539. There are five specimens of this species before me, and as three have the apical segment of abdomen with a large 234 _ impression, and the tip notched, they are evidently males, as the other two, evidently females, have the apical segment different. It appears to be very close to bsnotatus, but in that species the sexual differences of the rostrum, antenne, and legs are very marked. In the present species the only distinct ones are in the abdomen. The rostrum is perhaps a trifle shorter in the male than in the female, but its punctures, and the insertion of antenne, are practically identical. The female may be distinguished from the female of binotatus by the prothorax being covered all over with large granules or small tubercles. On bznotatus the prothorax is entirely without granules for a considerable space along each side of middle. This species also has the third interstice gently and regularly elevated from near the base to beyond the middle. On that species the third is elevated into a small but distinct tubercle near the base, then depressed, and about the middle gently undulated, or elevated into feeble tubercles. On the pro- thorax there is a small, elongated (but easily abraded) fascicle on each side of middle; in the middle itself there is an obscure whitish spot. On the elytra there are rather numerous small fascicles on the third and fifth interstices, and sometimes on others. The narrow white spots are on the third about middle, on the fifth near it, on the seventh beyond middle, and three or four on the ninth; but they are sometimes obscured, and are easily abraded. EPISODIOCIS INCONSTANS, Nh. Sp. 3g. Blackish, antenne and tarsi reddish. Moderately ‘clothed with rusty-brown or ochreous-brown scales, obscurely variegated with sooty ones; a few stout whitish scales on apical portion of elytra. Head with dense partially-concealed punctures. Rostrum rather long, thin, and parallel-sided; with dense punctures, moderately large and distinct in front of antenne, larger and partially concealed behind same. Scape inserted about two- fifths from apex of rostrum. Prothorax rather small, moderately transverse, sides strongly rounded, apex more than half the width of middle; with very dense partially-concealed punctures. Hlytra much wider than prothorax, base lightly trisinuate, sides parallel to slightly beyond the middle; with rows of large, more or less oblong punctures, in places partly ‘concealed, and becoming smaller posteriorly; interstices with dense punctures; third with a small subfasciculate tubercle near base, and another in middle, fifth with two in similar positions, and another fairly close to apex. Under-surface with dense, partially-concealed punctures. With a wide shallow depression, common to metasternum and to basal 235 segment of abdomen. Vemora stout, strongly dentate, hind pair not extending to tip of abdomen. Length, 5-6 mm. Q. Differs in having the rostrum longer and thinner, punctures concealed only about base; scape inserted somewhat nearer the middle of rostrum, and basal segment of abdomen somewhat convex in middle. Hab.—New South Wales: [llawarra (H. J. Carter and H. W. Brown); Wollongong (A. M. Lea); Queensland: Mount Tambourine and Cairns (Lea). Type, I. 1546. Rather close to mzcroderes, but smaller, less densely clothed, and with more acute femoral teeth. The elytral tubercles are rather small, but being clothed with darker scales than on the surrounding parts they are fairly distinct. On the type male there is a small spot of white scales on the third interstice of each elytron beyond the second tubercle, but four other specimens are without such spots. The speci- men from Cairns (a female) has sooty scales forming several obscure transverse fasciez on elytra, the subbasal and median tubercles on the fifth interstice are very feeble, and there is no subapical one. PROTOPALUS HIRTICORNIS, Nn. sp. d. Black. Moderately clothed with ochreous and stramineous scales and sete; elytra with long blackish hairs on suture and close to same about middle; third interstice with a conspicuous pale fascicle near summit of posterior declivity; antennze with numerous long, blackish hairs, on one side of five apical joints of funicle, and of basal joint of club. Head strongly convex; with sparse, normally-concealed punctures, a very feeble median ridge between eyes. Rostrum long, inflated about base and again at apex; with coarse, irregular, partially-concealed punctures, but in front with smaller and clearly-defined ones, and with a narrow, impressed line. Antenne long and thin, inserted almost at tip of rostrum; scape passing eyes a short distance, almost as long as funicle and club combined; funicle with two basal joints very long, distinctly longer than the five apical joints and club combined, first about once and one-half the length of second; club with oblique sutures. Prothorax strongly convex, subconical, lightly transverse, with large round granules or small tubercles, regularly disposed, with a strong but not continuous median carina. LHlytra strongly convex, about one-fourth wider than prothorax, widest across shoulders, thence with oblique sides to near apex; with rows of large, round punctures, becoming small posteriorly ; suture distinctly raised in middle and with numerous short 236 transverse ridges, elsewhere with sparser and more feeble ones. Mesosternal receptacle slightly cavernous, walls thin. Legs long and thin; front coxz with a small tubercle; femora lightly dentate, hind ones passing apex of elytra. Length, 114-15$ mm. @. Differs in being more robust, the elytra less wedge- shaped. Rostrum shorter, with smaller punctures, sparser clothing, and without an impressed line at apex. Antenne much shorter, scape not passing eyes, first joint of funicle shghtly shorter than second, the five apical joints and base of club without special hairs. Basal segment of abdomen more convex. Legs much shorter, and hind femora just passing apex of elytra. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1464. In general appearance much like schonherri variety antennarius, but mesosternal receptacle slightly cavernous and shoulders narrower. The antennz of the male are very similar, but on schonherri, and on its variety, the long hairs are confined to the funicle, but on this species there are some on the basal joint of club as well (on some small ones, how- ever, the long hairs are very sparse on the club). The whitish spot on the sutural ridge is also not present on this species. Cristatus has wider elytra, without pale fascicles, and antennz very different. TJectws is smaller, with rostrum of female (the only sex at present known) much shorter, and clothing very different. The antennz shoulders and clothing are very different to those of dromedarius. All the specimens (sixteen) under examination were taken at night at Malanda on an old stump. CRATOMEROCIS, 0. g. Head rather small. Eyes rather large, facets rather coarse. Rostrum long, thin, and curved. Antenne thin; scape about the length of funicle; two basal joints of funicle elongate; club elliptic ovate. Prothorax transverse, base bisinuate. Scutellum small. Hlytra subcordate, base trisinuate. Pectoral canal deep, terminated between middle coxe. Mesosternal receptacle U-shaped; slightly cavernous. Metasternum rather short; episterna distinct. Abdomen wide, intercoxal process wide, all sutures free, two basal segments large. Legs rather long; femora stout, dentate; tibize compressed, hind pair strongly faleate; tarsi thin, third joint moderately wide and deeply bilobed. Convex, squamose, fasciculate, winged. Close to Onidistus, but the hind tibiz conspicuously faleate and forehead not quadrisinuate. The receptacle is slightly ‘cavernous, in which it agrees with O. araneus and 237 subfornicatus, but in O. nodipennis it is decidedly open. From Paleticus it is distinguished by the hind tibie and free abdominal sutures. The only known species is very con- Spicuous on account of its spots of flavous scales. The hind femora are ridged on the lower-surface, the ridge itself being angulated in two places, somewhat lhghtly at the basal third, and strongly at the apical third; in consequence the hind femora from some directions appear conspicuously bidentate, from others, however, they appear to be unidentate only. CRATOMEROCIS FLAVONOTATUS, Nh. Sp. Black; antennz (club excepted) and tarsi reddish. Densely clothed with dark chocolate-brown or blackish scales, closely applied to derm, but interspersed with stout suberect ones, in places compacted into feeble fascicles. Prothorax with a fairly large, round, medio-basal spot of flavous scales, each side near apex (but invisible from above) with a smaller spot, each elytron with two small spots: one on the third interstice, the other on the eighth. Head with dense, concealed punctures. Rostrum slightly longer than prothorax, parallel-sided except at base; basal portion with punctures in rows separated by distinct ridges, elsewhere with sparse and minute punctures. Scape inserted about two-fifths from apex of rostrum. Prothorax moderately transverse, sides strongly rounded, apex about half the width of base; with normally-concealed punctures. Llytra about one-third wider than prothorax, not twice as long as wide, base strongly trisinuate, sides feebly rounded to beyond the middle, thence rapidly diminishing in width to apex, which is obtusely notched; with rows of large, partially-concealed ‘punctures; third and fifth interstices each with two feeble elevations, supporting fascicles; a few small granules (some- ‘times concealed) on suture. Hind femora with a very strong ‘tooth, and a dentiform process between tooth and base, the other femora acutely, but not very strongly, dentate. Length, 5-6 mm. Hab.—Queensland: Kuranda (G. E. Bryant, F. P. Dodd, and H. H. D. Griffith); Mossman River (Macleay Minseum)., Pype, 1. 1497. A very distinct species. With the head in position it appears to have the punctures entirely concealed by scales, but when removed from the body the base is seen to be covered with dense, clearly-defined punctures on a space defined from the densely-clothed part by an evenly-curved (not quadri- ‘sinuate) line. The sexes are not very sharply defined. The male has a slightly stouter rostrum than the female, with the 238 basal punctures more advanced towards the middle, and the antennz inserted a trifle closer to the apex of rostrum. RH#ABOCNEMOCIS, n.g. ead of moderate size and evenly convex. LEyes large, coarsely faceted. Rostrum long, thin, and curved. Antenne: thin ; scape inserted rather close to apex of rostrum, and con- siderably passing same; two basal joints of funicle moderately long; club elongate-elliptic, sutures oblique. Prothoraz trans-- verse, sides rounded, base almost truncate. Scutellum distinct. Elytra much wider than prothorax, sides parallel to beyond the: middle. Pectoral canal narrow, deep, terminated between middle coxz. Mesosternal receptacle U-shaped, walls thin ;. shghtly cavernous. Metasternum slightly shorter than the fol- lowing segment. Abdomen large, suture between two basal segments indistinct in middle, third and fourth comparatively large, their combined length distinctly more than that of second or fifth. Legs long; femora stout, strongly dentate, hind pair- passing apex of elytra; tibis compressed, faleate; tarsi thin,. first and fourth joints elongate. Squamose, fasciculate,. winged. Some of the characters, especially of the under-surface, — appear to denote an approach to Pezichus, but the legs are very different. and the elytra are without the small fascicles of whitish scales just beyond the middle that are almost in- variably present in the allies of Protopalus. It appears to be- allied to Onidustus, and may be placed after Cratomerocis, from which it differs in its unidentate hind femora, abdominal: sutures, and base of head. RH#BOCNEMOCIS POSTERUS, N. Sp. ¢. Black; rostrum, antennz, and tarsi more or less red-- dish. Rather densely clothed with brownish scales, variegated . in places with paler and darker ones; with fairly numerous,. suberect scales interspersed. Head with punctures concealed. Eyes separated less than - width at base of rostrum. Rostrum slightly longer than pro- thorax, somewhat dilated towards but notched on each side of base ; basal third with rather coarse, concealed punctures, else- where with sparse and small ones. Scape inserted about one-- fifth from apex of rostrum. Prothorax moderately transverse, sides strongly rounded, apex more than half the width of middle ; punctures dense, but normally concealed. Hlytra sub-. cordate, base distinctly trisinuate ; with rows of rather large, - (10) There are several spots of whitish scales on the elytra, but. not elevated into fascicles. 239 partially-concealed punctures; third interstice feebly elevated in parts. Under-surface with fairly large, partially-concealed punctures. Length, 5 mm. Q. Differs in having the rostrum rather more curved. punctures concealed only near extreme base; antenne some- ‘what shorter, and not inserted so close to apex, and legs some- what shorter. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1496. The posterior declivity is rather conspicuously variegated with spots or stripes of black and almost flavous scales; on one specimen the balance of the scales there are of a whitish-grey, on the other they are brownish. On other parts of the elytra — there are a few feeble greyish spots. On the prothorax the ‘clothing is almost uniformly pale-brownish, but along the middle it forms a median line, apparently concealing a very feeble carina. On the sterna the scales are more or less ochreous. The teeth of the hind femora are very large, more ‘than thrice the size of the others. PSEUDONIDISTUS CALVICEPS, N. sp. Black ; antennze and tarsi reddish, rostrum and parts of the legs diluted with red. Upper-surface densely clothed with rusty-brown or muddy-brown scales, interspersed with stout erect ones, that in places are compacted into fascicles. Head densely clothed in front, but elsewhere bald and shining ; trisinuate, median sinus widest, the others immedi- ately behind eyes. Rostrum moderately long, basal third -carinated along middle, and with coarse concealed punctures, elsewhere shining and with minute punctures. Antennz thin, inserted about one-third from apex of rostrum. Prothoraz ‘moderately transverse, with four obtuse tubercles crowned by fascicles across middle ; with large, irregularly distributed, and normally-concealed punctures. L/lytra briefly subcordate, at base no wider than prothorax, but sides from base obliquely dilated, then parallel, and then arcuate to apex; with irregular rows of very large partially-concealed punctures, becoming smaller posteriorly; each shoulder and third and fifth interstices with obtuse, fascicle crowned tubercles. Meta- sternum with a curved row of large punctures on each side. Basal segment of abdomen also with a curved row on each side, its suture with second marked in the middle by a con- ‘spicuous fovea. Femora clavate, strongly and acutely dentate; tibie thin and compressed. Length, 45 mm. Hab.—Queensland: Mount Tambourine (A. M. Lea) ; New South Wales: Tweed River (H. J. Carter). Type, I. 1522. 240 In size and genera! appearance very close to cordatus, but forehead with median sinus wider and shallower, no punctures at base of second abdominal segment, and elytra with a tubercle on each shoulder. The abominal fovea is much as on cordatus, although it was not mentioned in the description of that species. The under-surface of both specimens is almost glabrous, but this may be due to abrasion. The rostrum of the specimen from the Tweed River is slightly longer than that of the type. PALETONIDISTUS FOVEICOLLIS, Nn. Sp. Black; antenne (club somewhat darker) and tarsi red. Sparsely and unevenly clothed, but legs densely clothed. Head with forehead obscurely quadrisinuate, but with a distinct median carina. Rostrum moderately long, evenly curved, sides slightly dilated at middle (where antennz are inserted); on basal fourth with irregular rows of coarse, partially-concealed punctures, elsewhere shining and with small and rather sparse ones. Scape slightly shorter than funicle; two basal joints of funicle subequal in length, but first stouter than second; club elliptic-ovate. Prothorax lightly transverse, sides rather strongly rounded, apex more than half the width of base, near base in middle with a deep and moderately large fovea. LElytra distinctly but not much wider at base than prothorax, widest at about middle; with irregular rows of rather small, squamiferous punctures, not in strie except at sides; with a large tubercle on third interstice near base, and a much smaller one in middle, a large one on second interstice about summit of posterior declivity, and a smaller one before middle ; base on each side of scutellar region with a small shining tubercle. J/esosternal receptacle rather strongly elevated and sloping downwards to base and apex. Metasternum with a row of large punctures behind each middle coxa. Abdomen with first segment slightly longer than second and third combined, its suture with second deep at sides, and distinct across middle, each side near base with a few large punctures; apical segment rather densely punctured. Legs long; femora rather strongly dentate, hind ones just passing apex of elytra. Length, 84 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1463. Differs from trisinwatus in its sparse punctures, conspicuous. medio-basal fovea of prothorax, number and disposition of tubercles, mesosternal receptacle more conspicuously elevated, distinct suture between two basal segments of abdomen, hind femora passing elytra, etc. J/lidgea, to which at first glance it appears to belong, has coarsely-faceted eyes, edentate femora, 241 etc. To the naked eye the upper-surface has a dingy-greyish appearance. On the elytra the posterior declivity has denser and paler scales than elsewhere, but the tubercles are crowned with sooty scales. On the prothorax there are six fascicles, of which the outer median ones are smaller and paler than the others. There are no distinct punctures on the prothorax, although most of its derm is exposed. The four large elytral tubercles are of even size, the smaller ones between them are crowned with scales, rendering them fairly conspicuous; there are also a few tubercular swellings on the sides. POROPTERUS CONSTRICTIFRONS, 0. sp. Black ; antennz, tibial hooks, and claws more or less red. Irregularly clothed with muddy-brown and ashen scales, a few almost black; each elytral puncture with one wide scale. Head with minute punctures and very finely shagreened ; ocular fovea small but clearly defined. Rostrum rather long and thin, slightly dilated to apex, with numerous and usually clearly-defined punctures. Antenne inserted about two-fifths from apex cf rostrum, second joint of funicle distinctly longer than first. Prothorax about as long as wide, sides strongly rounded, apex produced but not bilobed; with four rather large round tubercles across middle, the outer ones smaller and nearer the apex than the inner ones, towards base with some smaller subobsolete ones; subapical constriction very deep and continuous across summit. Llytra elongate-ovate, widest at about basal third; with rows of large punctures becoming smaller posteriorly; third interstice with two fairly large tubercles, one at about basal fourth, the other crowning the posterior declivity, which is rather long; with several feeble tubercular swellings elsewhere; with some shining squamiferous granules on and near suture and on tubercles. Mesosternal receptacle U-shaped, walls thin but rather stouter at base than elsewhere. Abdomen with straight, deep sutures to three middle segments. Legs long and thin; posterior femora passing apex of elytra; third tarsal joint wide and deeply bilobed. Length, 11 mm. Hab.— North Queensland (Blackburn’s collection). Type, I. 1296, in South Australian Museum. The subapical constriction is deep and continued from side to side, causing the prothorax to appear as if a wire had been bound across it when soft. This character will readily distinguish it from rhyticephalus. In many species of the genus the constriction is deep at the sides, but not continuous across the summit. The type appears to be somewhat abraded, and is probably a female. 242 POROPTERUS PARVIDENS, Nl. Sp. ¢o. Black; antenne tibial hooks and claws more or less red. Rather sparsely clothed with large ashen-grey scales, usually becoming much darker on tubercles; under-surface and legs with ashen scales irregularly mixed with sooty ones, the legs with stout sooty setz as well; apical half of head and rostrum to antennez rather densely clothed. Head with minute punctures, and very finely shagreened ; ocular fovea rather large but partly concealed. Rostrum moderately long, sides very feebly incurved to middle, obsoletely carinated along middle to antennez, apical third with fairly dense but rather shallow punctures. Antenne inserted about two-fifths from apex of rostrum; scape rather short; first joint of funicle stouter, but slightly shorter than second. Prothorax slightly longer than wide; with two large median tubercles; subapical constriction interrupted in middle, deep and irregular on sides; elsewhere deeply and irregularly grooved. Scutellum small. Hlytra suddenly, but not much, wider than prothorax, subparallel-sided to near apex; with large distant punctures, larger on sides than elsewhere; with four large tubercles—two at basal fourth and two crowning the posterior declivity; between these four smaller tubercles placed transversely, the inner ones much larger than the outer ones, but considerably smaller than the four large ones; shoulders tuberculiform. J/esosternal receptacle rather large and elevated at base, emargination with thin widely-U-shaped walls, sloping down to front coxe. Abdomen with basal segment as long as three following com- bined, these with straight sutures, those of the third and fourth deep. Legs long and thin; femora subclavate, very feebly dentate, posterior passing elytra; third tarsal joint rather wide and deeply bilobed. Length, 83-9 mm. Q. Differs in having somewhat shorter legs (but the hind femora pass the elytra), rostrum longer, thinner, clothed only near base and with smaller but more clearly-defined punctures, and antennz inserted not quite so close to apex of rostrum. Hab.—Queensland: Kuranda (G. E. Bryant): Cairns (H. W. Cox and A. M. Lea). Type, I. 1297, in South Aus- tralian Museum. In some respects an aberrant species and approaching Illidgea, but head not as in that genus, eyes larger and with smaller facets, abdomen with second segment distinctly longer than third, etc. It is a narrow, deep species, with large tubercles, some of which are sometimes obscurely diluted with red. The teeth of the four hind femora are so small that they could be readily overlooked: those of the others are 243 larger, but still small and more or less concealed by the- clothing. PoROPTERUS ORNATICOLLIS, n. Sp. Black; antennze and tarsi more or less red. Sparsely and irregularly clothed with scales varying from ashen to sooty, tubercles with black fascicles, but on prothorax varied with ochreous and whitish scales; legs rather densely clothed ; a small patch of pale scales near each eye. Head with fairly large but sparse and shallow punctures. Eyes with coarser facets than usual. Rostrum moderately long, somewhat dilated to apex; with numerous clearly- defined punctures. Antenne rather thin; scape inserted two-. fifths from apex to rostrum; second joint of funicle slightly longer than first. Prothoraz longer than wide, sides strongly rounded; apex produced and slightly concave, with a con- spicuous fringe about the concave portion; subapical con- striction deep and abruptly terminated at fringe; with a median carina, feeble near apex, but appearing at base as a scutellar lobe; with four fasciculated tubercles across middle, and two slightly behind the median ones; with large, round, irregularly-distributed punctures. Hlytra narrow and deep, not much wider than widest part of prothorax; sides with large and usually somewhat angular, distant punctures or- fovez, along middle and on posterior declivity much smaller ; third interstice with three distinct but rather small tubercles, the first at about basal fifth, the third near summit of pos-. terior declivity, the second halfway between the others; fifth. with three somewhat’ smaller tubercles, each placed slightly behind its fellow on the third; some small shining squami- ferous tubercles on suture and on tubercles. dM/esosternal receptacle shorter, but otherwise as in preceding species. Abdomen with first and fifth segments each about as long as the others combined, suture between first and second deep: at sides, but distinct across middle, the other sutures deep and straight. Legs long and thin; posterior femora passing apex of elytra; third tarsal joint wide and deeply bilobed. Length, 74-8 mm. fHlab.—Victoria: Bau Bau (Blackburn’s collection) ;- Queensland: Little Mulgrave River (H. Hacker). Type, I. 1298, in South Australian Museum. On the prothorax there is a distinct irregular patch of pale scales, commencing at the median fascicles and continued along the carina to the base; there are also two small medio- apical whitish fascicles, feebly indicated from behind, but very distinct from in front. Many of the elytral punctures: have a transverse impression from each side. I cannot satisfy - 244 myself as to whether one specimen has a minute scutellum or not, but the other is certainly without one. Both specimens appear to be feminine. POROPTERUS CONVEXUS, 0. sp. Black; antenne of a dingy-red. Sparsely clothed with thin scales varying from muddy-brown to sooty; but legs, especially the tibiz, rather densely clothed. Head with fairly large but sparse and shallow punctures in front, towards base with numerous small punctures and finely shagreened. Ocular fovea rather large and transverse. HKyes coarsely faceted. Rostrum moderately long, sides slightly swollen between base and antenne, and feebly dilated in front of same to apex ; with dense, clearly-defined punctures, coarser behind than in front of antenne, but with an impunctate space along middle between same. Antenne inserted about two- fifths from apex of rostrum; scape rather short; first jomt of funicle stouter but scarcely, if at all, longer than second. Pro- thorax slightly longer than wide, sides rounded in middle, apex feebly produced and rounded; subapical constriction deep, regular and continuous; with four very obtuse tubercles across middle; carina represented only by a feeble scutellar lobe; sides with very few punctures, but with a deep groove at base. Scutellum minute. Hlytra narrow, strongly convex, much deeper than wide; non-tuberculate; sides obscurely striated and with comparatively sma]] and distant punctures, elsewhere with very small punctures, but in places transversely impressed. Mesosternal r eceptacle with basal portion rather large and con- ‘vex, emargination semicircular. Abdomen with first segment as long as three following combined, and somewhat longer than fifth, its suture with second distinct at sides, but deeper and wider across middle, second somewhat shorter than third and fourth combined. Legs long and thin; hind femora passing apex of elytra; third tarsal joint moderately wide and deeply bilobed. Length, 85 mm. Tab.—Queensland: Cairns district (A. M. Lea). Type, 1. 1299, in South Australian Museum. A narrow, deep species, with non-tuberculate elytra; its -coarsely- faceted eyes are rather aberrant for the genus. Of the described species it is perhaps nearest to Jongipes, but that ‘species has wider and differently sculptured elytra and finely faceted eyes. The elytra when viewed from the side appear to be strongly rounded from the base to the basal fourth, and ‘then to sweep round evenly to the apex, so that it is difficult to decide as to where the posterior declivity commences. The ‘type is probably a male. 245 POROPTERUS RUBETER, Er. Var. A. Two specimens from Victoria (Victorian Alps, Blackburn’s collection ; and Bright, H. W. Davey) differ from Tasmanian specimens of this species in being smaller (53-64 mm.), and with a large and conspicuous pale triangle on each elytron ; the triangle commences on each shoulder, extends to the second interstice near the middle, and then has a rounded outline to the side. On the rest of the upper-surface, however, the clothing is less variegated and more uniformly distributed than on Tasmanian specimens, and the fasciculate tubercles on the elytra are less conspicuous. OPHRYTHYREOCIS, 0. g. Head small, forehead somewhat sinuous. Eyes small, pro- minent, distant, coarsely faceted. Rostrum moderately long and not very thin, lightly curved. Antenne moderately long, scape inserted about one-third from apex of rostrum; two basal joints of funicle elongate; club ovate. Prothoraz transverse, sides rounded, apex produced. Scutellum round and conspicuously elevated. Llytra at base not much wider than prothorax, and about twice as long. Pectoral canal deep and wide, terminated between or near middle coxe. Meso- sternal receptacle of variable shape, cavernous. Metasternum short ; episterna indistinct. Abdomen with two basal segments large, third and fourth usually depressed below level of second and fifth. ZLegs short; femora indistinctly grooved and very feebly dentate; tarsi with third joint rather wide and deeply bilobed. This genus is proposed for three weevils having the general appearance as of minute members of the lithodermus group of Poropterus, but distinguished from Poropterus by the femora. But the genus is distinct on account of the conspicuously ele- vated scutellum, a character almost unique in the Australian Cryptorhynchides. The scutellum also is not clothed with scales, but has a greyish, waxy-looking coating. With them, but as somewhat aberrant on account of its longer legs, has been associated Poropterus valgus, which has a similar scutellum. Its front femora are certainly neither grooved nor dentate, nor are the four hind ones distinctly grooved, but as on a close examination very feeble grooves are traceable, and extremely small teeth) may be seen amongst the scales, it appears desir- able to transfer it from Poropterus, in which it would certainly not have been placed had I previously observed the femoral teeth. (11) The teeth cre visible with difficulty and from one direc- tion only. 246 Legs long, front tibiz twisted at apex... valgus Legs short, front tibize not twisted.

Densely clothed with rusty-brown scales, interspersed with numerous stout, sub— erect ones, in places forming fascicles. Head partly bald, and with the forehead lightly sinuous.. Hyes latero-frontal, small and very. prominent. Rostrum. rather -wide, sides lightly incurved to middle; behind antennz with numerous erect scales, evidently concealing coarse punctures, in front with dense punctures. Prothorax decidedly transverse, moderately convex, apex about half the: width of base; with dense, partially-concealed punctures. Elytra subcordate, sides rather strongly rounded, base trun-- cate; with rows of large, partially-concealed punctures. Third and fourth segments of abdomen distinctly depressed. below second and fifth. Femora stout, lightly but (from some: directions) distinctly dentate. Length, 3 mm. AHab.—Queensland: Mount Tambourine, sieved from rotting leaves (A. M. hea). Dype, 1. 1517. On the prothorax six very feeble fascicles may be traced. On the elytra there are very feeble ones on the second and fourth interstices. Some of the erect scales, both isolated and in the fascicles, are sooty. So far as it is possible to judge, on account of the clothing, the punctures in the elytral rows are- quite as large near apex as elsewhere. The type is almost certainly a male. OPHRYTHYREOCIS VALGUS, Lea. A specimen from Victoria (Blackburn’s collection) possibly belongs to this species: if it is, it is a female, and differs from the type in being smaller (3% mm.), with somewhat less pro- minent eyes and front tibie not distorted at apex. The rostrum- is thinner, with smaller but not concealed punctures, and clothed only at base. The scutellum is as conspicuously elevated as is that of the type, but the clothing or exudation- on it is of a redder tone. PSEUDOPOROPTERUS IRRASUS, 0. Sp. Black; antenne and tarsi reddish. Clothed with dingy” scales; w oh rather thin suberect ones scattered about. 247 Head with very large punctures, partially concealed to- wards base. Rostrum stout, slightly dilated in front of antennz, parallel-sided behind same; with four rows of very large punctures, becoming smaller and irregular in front. Scape moderately stout, inserted two-fifths from apex of rostrum, shorter than funicle. Prothorax moderately trans- verse, sides strongly rounded, base truncate and more than twice the width of apex, with very large, deep punctures, crowded together; with a somewhat sinuous median carina. Elytra not much wider than prothorax, shoulders very feebly produced, sides rounded, posterior declivity strongly rounded; with rows of very large, but in places partially- concealed punctures; interstices each with a row of small, shining granules. Abdomen with very large punctures on two basal segments, fifth with crowded smaller ones, third and fourth conspicuously depressed below level of others. Femora moderately long, strongly grooved, edentate, hind pair extending to tip of elytra. Length, 33-5 mm. Hab.—Queensland: Bluff (A. M. Lea). Type, I. 1889. In appearance fairly close to Acalles dorie 22) but wider, with larger punctures and different clothing. On the upper- surface there are numerous rather dingy light-brown scales scattered about in some spots (some paler than others), but quite regularly clothing the suture; and there are numerous, but very indistinct, sooty-brown scales. On slight abrasion, however, the spotted appearance is lost. On the under- surface and legs the scales are mostly pale and rather thin, much like the suberect ones on the upper-surface. In a direct line the elytra are about once and one-half the length of pro- thorax, but along the curve they are fully twice as long. There are a few indistinct granules on the prothorax, mostly on the flanks. Five specimens in the British Museum (from the Ade- laide River) appear to represent a variety. They differ in having the pale-brown scales on the upper-surface almost confined to the apical half of the suture, elsewhere the scales are of a more or less sooty-brown, but with rather distinct whitish spots scattered about; of these there are from one to three on the second interstice, one or two on the third, and one on the fifth. One of them has the clothing on the apical portion of the suture whitish, and only three punctures (but those unusually large) on the second abdominal segment. EKURYCIS, n. g. Head wide, partially-concealed from above, base evenly convex. Eyes small, widely separated, coarsely faceted. (12) To be referred to Pseudoporopterus. 248 Rostrum wide, feebly curved; scrobes narrow and deep in front, but wide and shallow behind. Antenne moderately thin, inserted nearer apex than base of rostrum; scape shorter than funicle; two basal joints of funicle elongate; club elliptic-ovate. Prothorax strongly transverse, sides strongly rounded, apex produced. Scutellum absent. LHlytra scarcely longer than wide, sides strongly rounded, base with produced tubercles. Pectoral canal deep and wide, terminated just behind front cox. Mesosternal receptacle rather large, elevated in front, emargination strongly transverse, cavernous. Metasternum very short; episterna narrow. Abdomen rather large, first segment almost twice the length of second, its suture with ‘that segment distinct only at sides, third and fourth very short. Legs short and stout; femora edentate, shallowly grooved; tarsi lhnear, spongiose on lower surface. Briefly ovate, tuberculate, densely squamose, apterous. The tarsi might fairly be regarded as linear, as the third joint is almost the exact width of the second, and this would associate the genus with Scolyphrus, Agenopus, and a section” of Poropterus and of Euryporopterus. From Scolyphrus it is distinguished by the very different base of elytra; from Poropterus by the grooved femora, and from Huryporopterus by the convex base of head. The generic diagnosis of Agenopus is simply a brief comparison with Poropterus and Mormosintes, but the description of A. agricola indicates a very different looking species to the present one. EURYCIS MULTINODOSUS, 0. sp. Black; antenneze of a dingy-red. Densely clothed with muddy-brown scales, in places appearing as fascicles owing to numerous small tubercles. Head with dense punctures. Rostrum scarcely as long as prothorax, but little more than twice as long as greatest width, sides distinctly incurved to middle; with four rows of large, round punctures, becoming smaller and crowded at apex. Prothorax almost twice as wide as long, sides strongly rounded, apex about one-fourth the width of middle; with some small tubercular swellings, and with crowded, partially- concealed punctures. Hlytra not one-fourth longer than wide, sides nowhere parallel, and widest at about basal fourth; with irregular rows of large, more or less concealed punctures; interstices with numerous small tubercles. Under-surface with large, round, deep punctures. Length, 64-74 mm. Hab.—Australia (old collection). Type, I. 1516. The specimens were simply labelled 27/1/79 and 19/5/79, but are probably from South Australia. On one of them the scales are not at all variegated, but on the other there are 249 remnants of a transverse fascia at summit of posterior declivity. On the prothorax thirteen small tubercles (some of which are very feeble) may be counted; of these there are two near each margin, and eight are roughly arranged in the forms of two crosses, the basal piece of each of these being on the base halfway between the middle (where the thirteenth one is placed) and the side. On the elytra the tubercles are numerous, the most distinct ones are six at the base pro- jecting forwards; across the summit of the posterior declivity there is a row of six fairly large ones, elsewhere but few are conspicuous. PALETICUS LUTULENTUS, Nn. sp. 6. Black; antenne and tarsi reddish. Densely clothed with muddy-brown scales, in places variegated with black ones. With numerous stout and usually rather pale scales scattered about, and in places compacted into feeble fascicles. Head with concealed punctures. Ocular fovea rather wide. Rostrum long, sides lightly incurved to middle; basal half with concealed punctures, elsewhere shining and with small, clearly-defined ones. Scape inserted two-fifths from apex of rostrum, and slightly shorter than funicle; second joint of funicle longer than first. Prothorax moderately transverse, sides rounded and narrowed from base to apex, apex half the width of base; punctures concealed. Scutellwm minute. Hlytra much wider than prothorax, base strongly trisinuate, sides almost parallel to beyond the middle; with rows of large, round, and rather distant punctures, becoming small posteriorly; third interstice with a distinct tubercle at basal third, and another about middle; each shoulder tuberculate; with some small sutural granules. Abdomen with a deep curved impression on each side of base, ter- minating near middle in a fovea. Legs long; femora stout, strongly and acutely dentate, hind ones passing apex of elytra. Length, 8-9 mm. Q. Differs in having the rostrum longer and thinner, especially in front of antenne, coarse punctures less advanced towards middle; scape inserted slightly nearer the middle of rostrum, and two basal segments of abdomen gently convex instead of flat. Hab.—Queensland: Cairns district (E. Allen and A. M. Lea). Type, I. 1523. The suture between the two basal segments of abdomen is deep at the sides and distinct, although not deeply im- pressed, across the middle, but the segments are certainly not soldered together as in other species of the genus. In some respects it is allied to frontalis and cordipennis. There are four very feeble fascicles across the middle of the prothorax, 250 but at the apex the scales could not be regarded as forming fascicles. On the elytra they feebly crown the tubercles. On the upper-surface there are irregular patches of small sooty scales, having the appearance at the edges of the patches of being overlaid by the muddy-brown ones. PALETICUS INFLATUS, nN. sp. dg. Black; antenne and tarsi more or less reddish. Head with concealed punctures. Ocular fovea rather small. Rostrum about the length of prothorax, not very thin, almost parallel-sided ; basal three-fifths with coarse concealed punctures, elsewhere shining and with rather small clearly- defined ones. Scape inserted two-fifths from apex of rostrum,. the length of five following joints combined ; second joint of funicle longer than first. Prothorax moderately transverse,, sides gently rounded, apex more than half the width of base. Elytra short, subcordate; base, except for a slight median: sinus, truncate, and scarcely wider than prothorax, but sides dilated and strongly rounded; with rows of rather large punc- tures, becoming smaller posteriorly, the first not continuous to base; third and fifth interstices distinctly wider than the others, and feebly elevated ; with a few feeble sutural granules. Basal segment of abdomen concave along middle, with a deep curved impression on each side of base. Legs as in preceding species. Length, 7 mm. Q. Differs in having the rostrum somewhat longer and thinner, coarse punctures less advanced towards middle, scape inserted slightly nearer middle of rostrum, elytra narrower to- wards apex, and basal segment of abdomen convex across middle. Hab.—Queensland: Cairns district (A. M. Lea) ; Mount Bellenden-Ker (Solari Bros.). Type, I. 1524. The generic position of this species is somewhat doubtful,. as the shoulders do not clasp the prothorax, still it does not. appear advisable to propose a new genus on this character alone. The conspicuously dentate and non-grooved femora. distinguish it from Platyporopterus. The clothing is not alike on the two typical specimens. On the male there are minute scales varying from grey to sooty, lightly scattered about, but becoming dense on apical portion of elytra and on the legs;. it also has stout, sooty, suberect scales, not forming fascicles, but fairly numerous on prothorax, and on the elytra forming’ lines, more noticeable on the odd than on the even interstices.. The female was probably more densely clothed, but has evi- dently been considerably abraded, as there are irregular patches: of rather dense scales on the upper-surface; the dark, stout scales of the male are also replaced by muddy-brown ones. The female also has the third and fifth interstices feebly tuberculate- 251 -at the basal third; in the male the swellings there are scarcely traceable. The elytra, in addition to having strongly rounded sides, slope upwards from the base, so that when viewed from the sides they appear to be conspicuously elevated above the prothorax. In consequence of the median impression the basal segment of the male abdomen appears to be bilobed. EURYPOROPTERUS CRYPTODERMUS, Nn. Sp. ~ 3. Black; antenne and tarsi red. Densely clothed with muddy-brown scales; interspersed with numerous stout, sub- -erect ones, in places compacted into fascicles. Head with very dense, concealed punctures. Rostrum rather long and thin, sides lightly incurved to middle; with dense punctures throughout, but more or less concealed behind antenne. Antennz thin ; scape inserted about one-third from apex of rostrum. /rothorax strongly transverse, base strongly bisinuate, sides strongly rounded, surface uneven; with four feeble fascicles across middle and two at apex; with rather large, irregular, concealed punctures; and with a thin, con- cealed median carina. Scutellum not traceable. Llytra short, base strongly trisinuate, with shoulders strongly produced, sides gently rounded to beyond the middle ; with rows of large, rounded, more or less concealed punctures; third and fifth interstices each with a distinct fascicle at summit of posterior declivity, some feeble ones elsewhere. Punctures of under- surface concealed. Two basal segments of abdomen large, first as long as three following combined; a deep groove on each -side of base, flattened or feebly depressed in middle. Legs rather short; femora feebly grooved, edentate, hind pair scarcely extending to apical segment. Length, 6-7 mm. Q. Differs in having the rostrum somewhat thinner, shining, with less of the base concealed, antenne inserted not quite as close to apex of rostrum, and basal segment of abdo- men gently convex. Hab.—South Australia: Adelaide (J. G. O. Tepper and Blackburn’s collection); Victoria: Bostock. Type, I. 1779. Of the species previously referred to the genus the fascicles would associate it with annulipes and tenwifasciatus; from the latter it is readily distinguished by the edentate femora, but the antenne are quite as thin as in that species: from the former it is distinguished by the very different base of elytra. ‘The clothing is so dense that the prothoracic punctures are entirely concealed, and even many of the large elytral ones. On the under-surface the sutures between the metasternum and its episterna are concealed. From some directions the second joint of funicle appears to be distinctly longer than the first, but the two are really of almost exactly the same length. 252 OMYDAUS PARVICEPS, D. sp. Black; antennz and claws of a very dingy-red. Moder- ately clothed with scales, mostly more or less ochreous on upper-surface, mostly paler (usually whitish) on under-surface and legs. Head small, with dense and coarse punctures. Rostrum long, thin, and moderately curved; basal half with coarse, partially-concealed punctures, elsewhere shining and with small but clearly defined ones. Scape inserted about one-third from apex of rostrum; second joint of funicle longer than first. Prothorax scarcely wider than long, sides rather strongly rounded, apex about half the width of middle; with dense, round punctures, larger about middle than on sides; with a narrow median carina. Hlytra somewhat flattened, distinctly wider than prothorax, base strongly trisinuate, sides feebly diminishing in width to beyond the middle ; with rows of large, rough, suboblong punctures; interstices with crowded punc- tures. Under-surface with dense punctures. Femora strongly and distinctly dentate; tibiz compressed, punctures in rows separated by ridges, front pair strongly dentate in middle of lower-surface, and each with a small subapical tooth in addi- tion to the terminal hook. Length, 7-8 mm. Hab.—Queensland: Kuranda (F. P. Dodd and G. E. Bryant). Type, I. 1527. Allied to subfasciculatus, but decidedly narrower, front tibize distinctly arched on outer margin, and submedian tooth of lower edge more conspicuous; eyes larger and with finer facets ; punctures very different, etc. The rostrum is decidedly longer and thinner than in any previously described species, although very similar to that of the following one. On the upper-surface there are a few sooty scales, but they so closely ° resemble the derm on which they rest that they can be seen with difficulty. There is a small but conspicuous spot of ochreous-red, or ochreous, scales on the flank of each elytron, half-way between the middle and hind coxe. On the legs there are numerous rather long setose scales. The base of the head has numerous fine slightly-curved impressions, with small squamiferous punctures set at regular intervals, but they are normally concealed by the prothorax. The typical speci- mens (four) all have the basal segment of abdomen somewhat. concave, so they are presumably males. OMYDAUS TIBIALIS, 0. sp. Black ; antennz and tarsi of a dingy-red. Rather sparsely clothed with ochreous-red scales, of a brighter colour on upper- than under-surface. 253 Head rather small: with dense and coarse punctures. Rostrum rather long and thin, lightly curved; basal two-fifths with coarse punctures and feeble ridges, elsewhere shining and with small punctures. Scape inserted one-third from apex of rostrum ; second joint of funicle longer than first. Prothoraz and elytra with sculpture as described in preceding species. Under-surface with dense and rather coarse punctures. Basal segment of abdomen gently convex. femora strongly dentate ; tibie strongly compressed, each with a thin outer flange, ex- tending almost its entire length; with rows of punctures, separated by ridges. Length, 74 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, T. 1528. Readily distinguished from all previously described species by the wide and strongly compressed tibie. In general appear- ance it is like the preceding species, but the front tibie are without a median tooth. On the elytra the ochreous-red scales are more noticeable about the summit of the posterior declivity than elsewhere on the upper-surface; before and after same there are a few sooty scales, but they are indistinct, owing to their close resemblance to the derm. On the flank of each elytron there is a small conspicuous spot as on the preceding, and on several other, species. The type is probably a female. OMYDAUS SCULPTILIS, Nn. sp. Black; antennze and tarsi obscurely diluted with red. Irregularly clothed with scales, varying from almost white to rusty-brown. Head with some small, clearly-defined punctures; a deep narrow impression behind each eye. Rostrum moderately long, lightly curved, sides gently dilated towards base; about base opaque and with not very large punctures, elsewhere shining and with small ones. Scape inserted about two-fifths from apex of rostrum, very little shorter than funicle; two basal joints of the latter subequal in length. Prothoraz distinctly transverse, sides strongly rounded, and near apex deeply and narrowly impressed; with some large irregular punctures on sides and some smaller ones about apex; across median two-thirds with two deep and very conspicuous curved impressions, the median one interrupted in middle, the other not interrupted. lytra distinctly wider than prothorax, scarcely twice as wide as long, base trisinuate, sides sub- parallel to beyond the middle; with rows of large, distant punctures, becoming smaller towards sides and almost absent posteriorly. Under-surface with small and sparse punctures. Metasternum with a curved impression across middle. Abdomen with a strongly-curved impression towards base of 254 first segment, second distinctly longer than third, but not as long as third and fourth combined. Legs rather long; front femora distinctly dentate, the others edentate; front tibiz with a strong median tooth, and a small subapical one, ‘in addition to the terminal hook. Length, 114 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I ney As). The type of this very fine, but somewhat aberrant, species ‘is evidently in perfect condition, and its head has not been -detached so that the base could be examined. Most of the derm is nude, but on the prothorax there is a moderately -distinct line of pale scales towards each side, and a few scat- tered about on the sides and apex. On the elytra the suture (except about base) is distinctly clothed with rusty scales, and a few are irregularly scattered about elsewhere, but the paler ‘scales form feeble irregular spots, mostly about the middle. ‘The legs are moderately densely clothed. All the tibie are ‘finely serrated along their lower edges, but the serrations are obscured by scales; the median tooth of the front pair, how- ‘ever, is very strong. The elytra are not at all striated, except at the sides, although the punctures are seriate in arrange- ment. The prothoracic sculpture is very different to that of any other species of the genus. DECILAUS CURVIPES, 0. sp. Black; antennz and tarsi of a dingy-red. Moderately densely clothed with stout greyish or stramineous scales, inter- spersed with brown and sooty ones; denser on legs (where ‘they are interspersed with stout seta) than elsewhere. Head with dense, normally - concealed punctures. ‘Rostrum stout, moderately curved; behind antennze with several partially-concealed grooves. Antenne inserted about one-third from apex of rostrum; scape about the length of five following joints; club subcontinuous with funicle. Pro- thorax rather lightly transverse; sides strongly rounded, apex about half the width of base; with dense, large, round ‘punctures; with a short and feeble median carina. ELlytra -oblong-ovate, base not as wide as middle of prothorax; with rows of large, and generally somewhat transverse or angular, punctures. Mesosternal receptacle elevated from base to apex, emargination widely transverse. Two basal segments of abdomen with dense and coarse punctures, three apical seg- ments considerably below level of the others. Legs short and ‘stout; front tibiz strongly curved downwards in middle, with a subapical tooth, in addition to the strong apical hook ; ‘third tarsal joint rather deeply bilobed, but scarcely wider ‘than second. Length, 6-8 mm. 255 Hab.—South Australia: Ardrossan (J. G. O. Tepper). Dype, I. 1322. The apex of each of the front tibie is supplied with a curious red process, appearing like a rounded plate on its: upper-surface, and forming the apical hook on its lower- surface. The tibie are somewhat as in apicatus, but in that species the incurvature is confined to the upper-surface; in the present species the whole tibia is bent downwards at its middle. The apex of the rostrum is coarsely punctured, but the punctures are usually concealed. There are nine speci- mens under examination, two labelled Ardrossan, but the others without locality labels. They were apparently all taken many years ago, and all are more or less dingy; but this dingy appearance may be natural. The surface is every- where covered with a dingy-greyish or muddy-brown crust, possibly of a mealy nature, upon which chloroform has no apparent action. The darker scales are usually, but not always, thinner than the paler ones. DECILAUS HUMERALIS, Nn. sp. Black; antennz claws and tibial hooks of a dingy-red. Moderately clothed with fawn-coloured scales; much denser on tibiz than elsewhere. Head and rostrum apparently much as in preceding species; but club stouter and abruptly wider than preceding joints. Prothorax as long as wide, sides strongly rounded, base truncate; with dense, coarse punctures, in places feebly confluent; with a narrow, continuous median carina. LHlytra oblong-ovate, shoulders distinctly produced and clasping sides of prothorax; with rows of large, deep, and often angular punctures. Two basal segments of abdomen large, with very coarse punctures, especially on the second; three apical seg- ments conspicuously depressed below the others; apical one with dense punctures and a subapical fovea. Legs short and stout.. Length, 84 mm. Hab.—Australia (old collection). Type, I. 1323. The type is covered with the same muddy-looking indumentum as are the specimens of the preceding species ; the scales may normally be paler than as described, as where- they were covered up (at the base of the head) they are of a rather pale stramineous. The front tibie are armed much as in the preceding species, but they are not bent inwards. It differs also in its larger elytral punctures and conspicuous prothoracic carina. The type was probably from South. Australia. 256 DECILAUS ORDINARIUS, N. Sp. Dark-brown or black; antennz and tarsi of a dingy-red. Densely clothed with stout stramineous or muddy-grey scales, sometimes sooty; but uniformly pale on under-surface of body and of legs. Head with dense but comparatively small punctures. Rostrum moderately long and rather thin, sides lightly in- curved to middle, base considerably wider than apex, and with coarse crowded punctures, elsewhere with smaller but sharply-defined ones. Antenne thin, inserted slightly nearer base than apex of rostrum; scape scarcely as long as four following joints combined; first joint of funicle almost as long as three following combined, second as long as third and fourth combined. Prothorax strongly transverse, sides strongly rounded, apex less than half the width of base; with dense, round, deep, and fairly large, but partially-concealed punctures. Hlytra oblong-cordate, shoulders feebly rounded and scarcely wider than prothorax; with rows of fairly large punctures in distinct striz; interstices much wider than - seriate punctures, themselves with dense but more or less con- cealed punctures. Mesosternal receptacle like half of an elevated ring. Abdomen with large, round, deep punctures on all segments, but largest of all on second, no segments depressed. femora stout, rather strongly grooved, lightly dentate. Length, 53-6 mm. Hab.—Northern Territory (Blackburn’s collection) ; Queensland: Bloomfield River (C. French). Type, I. 1324. An ovate ordinary-looking species, but with dentate femora. From the Tasmanian coryssopus (also so armed) it differs in its much larger punctures, of both prothorax and abdomen, and very different clothing. The scales are sparser and larger on the prothorax than on the elytra. The first joint of the funicle is unusually long. DECILAUS BIFURCATUS, HN. Sp. ¢. Black; antennz and tarsi red. Moderately densely clothed with stout and feebly variegated, but more or less dingy-brown scales, denser on legs than elsewhere. Head with crowded partially-concealed punctures. Rostrum stout, sides lightly incurved to middle; with moderately large punctures. Scape inserted two-fifths from apex of rostrum, the length of four basal joints of funicle; the two basal ones of these subequal in length. Prothorax almost as long as wide, sides strongly rounded; with dense, round, partially-concealed punctures, of rather small size (for genus); with a very feeble median carina. SHlytra rather 257 short, base trisinuate; with rows of large punctures in light strie; interstices on basal half the width of, or narrower than, seriate punctures, but becoming wider posteriorly. Mesosternal receptacle distinctly raised; emargination widely transverse. Abdomen with small but rather dense partially- concealed punctures; first segment obliquely sulcate on each side of base, and with a feeble tubercle on each side of middle. Femora stout, strongly grooved, and feebly dentate; hind tibie with apical hook bifid; third tarsal joint wide and deeply bilobed. Length, 6-7 mm. @. Differs in having the rostrum somewhat longer and thinner, with smaller punctures, abdomen non-tuberculate and hind tibiz with apical hook simple. Hab.—Victoria: Alps, Mount Hotham, Fern Tree Gully (Blackburn’s collection). Type, I. 1325. In general appearance fairly close to tcbialis, and with very similar hind tibiz, but clothing of under-surface of male very different. The clothing there is somewhat paler than that of the upper-surface, but is otherwise very little different. The teeth are fairly distinct on the front femora, but scarcely traceable on the others. DECILAUS OOSOMUS, N. sp. Black ; antenne and tarsi of a rather bright-red. Clothing not very dense. Head with crowded, partially-concealed punctures. Ros- trum moderately stout, sides lightly incurved to middle; with coarse punctures, irregularly grooved behind antenne. Antenne as described in preceding species. Prothorax rather strongly transverse, sides strongly rounded, base truncate; with dense, large, round, deep punctures, becoming much smaller at apex. //ytra short, sides strongly rounded, extreme base no wider than base of prothorax; with rows of large, round, deep punctures, in very feeble strie; interstices nar- rower than striz, even posteriorly. Mesosternal receptacle strongly elevated, like half of aring. Abdomen with irregular punctures. Femora stout, moderately grooved. Length, 33-45 mm. ffab.—South Australia: Port Lincoln (Blackburn’s col- lection). Type, I. 1326. A short species, with large punctures and conspicuously- rounded elytra. In general appearance it is something like moluris, but the elytral punctures are much larger and less oblong, etc. The prothoracic punctures are about the size of those of cuniculosus, but the elytral ones are much larger and differently shaped. The abdomen has large punctures on the first segment about the base and at its suture with the second, J 258 the second has also a few large ones; elsewhere the punctures are much smaller, dense on the fifth, and sparse on the third and fourth. The three typical specimens are apparently all somewhat abraded. On the prothorax the scales are rather elongate, and each is set in a puncture, some of them are sooty, but the majority are fawn-coloured; on the elytra the scales in the punctures are decidedly smaller, but otherwise similar to those on the prothorax; but on the interstices such scales as are left are more or less circular, and vary from almost white to sooty. On the under-surface the scales are usually longer and paler, and on the legs and head denser, than elsewhere. DECILAUS MIRABILIS, Nn. sp. Deep shining-black, tip of prothorax and tibize diluted with red ; antenne, tarsi, and apical segment of abdomen paler. Almost entirely glabrous. é Head with a few large punctures in front. Rostrum stout, sides lightly incurved to middle, with a strong median carina and two smaller sublateral ones, all three continued almost to apex ; with a row of strong punctures between each two carine. Antenne rather thin, inserted about one-third from apex of rostrum ; scape about the length of five following joints; club rather large. Prothorax strongly transverse, sides strongly rounded; with large, round punctures. SHlytra subcordate, base truncate, sides strongly rounded and widest at about basal third ; with rows of large punctures, in moderate strize , inter- stices wider than strie, with fine punctures and minute wrinkles. Mesosternal receptacle like portion of an elevated ring. Abdomen with two basal segments no longer than third and fourth, fifth almost as long as four basal ones combined, with a rather large but shallow median fovea. Femora rather long, strongly grooved; front tibie lightly dilated from base to apex, the others narrowest at apex and subangularly dilated near base. Length, 14 mm. Hab.—Queensland: Mount Tambourine, in rotting leaves (A. M. Lea). Type, I. 1327. A minute black species, with unusually coarse sculpture. It may be necessary later on to refer it to a new genus. Under a Coddington lens the apical segment appears to be half the total length of the abdomen ; the first and second are unusually short, irregularly concave, and on the type the suture between them cannot be traced, so that the abdomen appears to consist of but four segments only. DECILAUS TRIVIRGATUS, Nn. sp. Of a dingy-castaneous, under-surface darker, elytra more or less deeply stained with black on suture and sides. Sparsely 259 clothed with stramineous sete, but in addition with fairly numerous long straggling hairs. Head with coarse punctures in front. Eyes separated about two-thirds the width of rostrum at base, smaller, and with coarser facets than usual. Rostrum stout, sides incurved to middle ; with rows of large punctures, in coarse series behind antenne, smaller and more crowded in front of same. Scape inserted about one-third from apex of rostrum, about the length of funicle; club large. Prothorax strongly transverse, sides strongly rounded ; with dense, coarse punctures. Flytra briefly subcordate, sides strongly rounded, and widest at about basal third; with rows of large punctures, in moderate striz ; interstices wider than strie. Mesosternal receptacle like the third of an elevated ring. Abdomen with coarse punctures on the first and second and fifth segments, the others depressed and impunctate. /emora stout and lightly grooved. Length, 14-14 mm. Hab.—Queensland: Mount Tambourine, in rotting leaves Gee fea)... Type, 1.21328. A dumpy little species, clothed with long straggling hairs, as in the Western Australian hispidus, but otherwise very different. The bald portion of the head is normally almost entirely concealed. The elytra are sometimes of a rather bright-red, with the suture and dark sides (the dark lateral part sometimes extends to the fifth interstice), causing them to appear trivirgate, but usually the two colours are not sharply contrasted. DECILAUS CALVICEPS, Nl. sp. Reddish castaneous, in parts more or less deeply stained with black. Moderately densely but somewhat irregularly clothed. Head with dense, partially-concealed punctures on a depressed space in front, elsewhere conspicuously bald. Eyes separated less than width of rostrum at base. Rostrum rather short and wide; with rather minute punctures, except about base, where they are more or less concealed; with a feeble median carina; notched on each side of base. Antennz thin; scape inserted one-third from apex of rostrum and the length of funicle; club large. Prothorax moderately transverse, sides strongly rounded; with a row of four tubercular swell- ings across middle; with a strong carina terminated before base and apex; with coarse more or less concealed punctures. Elytra subcordate, sides strongly rounded and widest across basal third; with rows of partially-concealed punctures in distinct strie. Mesosternal receptacle strongly elevated, emargination transverse. Abdomen with dense, concealed punctures, third and fourth segments somewhat depressed. J2 260 Femora stout, strongly grooved, and lightly dentate, front pair swollen in middle on one side; tibie thin. Length, 2 mm. Hab.—Queensland: Cairns district, in rotting leaves at Malanda (A. M. Lea). Type, I. 1329. A small, wide, and somewhat angular species, referred to the genus with hesitation; the prothoracic tubercles being a decidedly aberrant feature. The clothing varies from pale stramineous to ochreous, and is denser and paler on the meta- sternum and basal segments of abdomen than elsewhere. On the elytra a large space on each side (the derm there deeply stained with black) is conspicuously glabrous, the punctures there are very distinct, but the striation is irregular; the whole being somewhat reminiscent of Zenoporopterus mirus. Each shoulder is also glabrous. From some directions the femora appear to be thin, although they are really rather largely dilated in the middle. DECILAUS APICATUS, Lea. A specimen from Port Lincoln is probably a large and partly abraded female of this species. It differs from the types in being much larger (74 mm.) with the tibial hooks much smaller and blunt (probably worn down); its rostrum is not quite so stout, is slightly less curved, and with punctures nowhere concealed. The clothing is much sparser than on the types (probably due to abrasion), and the individual scales are somewhat narrower. DECILAUS TIBIALIS, Lea. A male from Bell (Queensland) differs from the type in being smaller (5 mm.), and with the paler scales more numer- ous about base and apex of elytra. Three females, from the Blue Mountains, have the elytra very similarly clothed. CARDIOPTEROCIS, ND. g. Head fairly large and evenly convex. Eyes rather small, widely separated, coarsely faceted. Rostrum of moderate length, rather wide, moderately curved. Antenne rather stout; scape inserted nearer apex than base of rostrum, and shorter than funicle; two basal joints of funicle rather long, the others very short; club ovate. Prothorax lightly trans- verse, sides strongly rounded, base almost truncate, apex pro- duced. Scutellum small. Elytra elongate-cordate. Pectoral canal deep and wide, terminated between middle coxz. Meso- sternal receptacle level with coxz, walls thin and widely U-shaped; open. Metasternum short; episterna represented 261 only posteriorly. Abdomen large, first segment as long as second and third combined, its apex lightly incurved to middle, second longer than third and fourth combined. Legs of moderate length; femora edentate, lightly ‘grooved; tibie almost straight; tarsi rather thin, but third joint deeply bilobed. This genus should be placed near Decilaus, and the typical species in size and shape is almost exactly like D. acerosus, although differing considerably in sculpture of under-surface and in clothing. The mesosternal receptacle is U-shaped, and at a glance appears similar to that of several species in which it has been described as slightly cavernous, but as the wall at its extreme base is very slight and quite vertical it has been regarded as open. ‘Treating it as such the genus, in an (at present M.S.) table of genera allied to Poropterus, would be associated with Poropterinus, whose prothorax and elytra are very different. Treating it as slightly cavernous, it would (in the table referred to) be asso- ciated with Hxithioides, whose mesosternal receptacle is con- spicuously raised and vaulted, and whose scutellum and meta- sternal episterna are absent. The sides of the elytra are pro- jected inwards, so as to cut off the front portion of the metasternal episterna, these in consequence appear tear- shaped, or like the upper portion of a note of exclamation (!) reversed. CARDIOPTEROCIS VARIEGATUS, 0. sp. Dark-brown, in places black; antenne and tarsi red. Densely clothed with variegated scales, and with numerous stout, suberect ones, scattered about. Head with dense concealed punctures. Rostrum almost the length of prothorax, parallel-sided; with dense punctures concealed towards base, towards apex smaller, denser, and clearly defined. Scape inserted not much nearer apex than base of rostrum. Prothorax regularly convex; with dense, concealed punctures. /lytra rather more than twice the length of prothorax, and at base but little wider, sides rather strongly and evenly rounded, and widest at about middle ; with rows of more or less concealed punctures. Under-surface with dense, concealed punctures. Length, 3 mm. Hab.—Queensland: Townsville (A. M. Lea). Type, I. 1526. The majority of scales on the upper-surface are of a dingy light-brown or fawn colour. On the prothorax there is a large sooty spot, of irregular shape, on each side of the base, and extending to the middle. On the basal half of the elytra the scales are mostly sooty, but there are none about the base itself ; on the apical half there are a few small sooty spots. On the 262 third interstice near base, and again for a short distance beyond middle, the clothing is almost white. On the under- surface the clothing is of a greyish-white. On the legs it is mostly greyish-white, but distinctly variegated with sooty. On the head it is mostly sooty, but on the rostrum whitish. The erect scales are usually, but not always, of similar colours to the depressed ones, amongst which they are placed. Occasion- ally a few are close together, but they do not form distinct fascicles. At a glance the four hind tibie appear to be angu- larly dentate at the outer base, but this is probably entirely due to their clothing. The type is probably a male. ROPTOPERUS CALVICEPS, Nn. Sp. gd. Blackish, in parts more or less obscurely diluted with red; antenne and tarsi red. Densely clothed with muddy-brown scales, with larger, greyish ones scattered about, and condensed into numerous fascicles on upper-surface. Head with most of surface bald and highly polished, a rather small space in front densely clothed. Rostrum wide at base, sides distinctly incurved to middle; basal half with coarse concealed punctures, apical half shining, and with minute ones. Scape short, inserted slightly nearer base than apex of rostrum. Prothoraz slightly longer than wide, sides moderately rounded; punctures normally concealed. Llytra elongate, base moderately trisinuate, shoulders less advanced than base near suture, sides moderately rounded; with rows of large partially-concealed punctures; with tubercular swell- ings supporting fascicles; of these there are four (including a small basal one) on the third interstice, three (including a small subbasal one) on the fifth, and two or three on the seventh. Under-surface with dense partially-concealed punctures. Basal segment of abdomen widely and shallowly depressed. Length, 52 mm. Hab.—Australia or Tasmania (Blackburn’s collection). Type, I. 1450. A narrow species somewhat suggestive of the New Zealand genus Phrynixus. On each elytron there are five fascicles larger than the others, and all fairly close together; each group commences with an antemedian one on the fifth inter- stice, and ends with one on the third at summit of posterior declivity. The type bears a green paper disc, signifying (if the specimen was sent by Mr. French) that it was from Tasmania. ROPTOPERUS SCUTELLARIS, 0. sp. Black; abdomen and rostrum of a dingy-red, antenne and tarsi paler. Densely clothed with soft scales, mostly 263 fawn-coloured, and with numerous fascicles on upper-surface. Head with most of surface densely clothed, with a narrow bald space. Rostrum wide at base, parallel-sided in front of antennze; basal third with coarse concealed punctures and a feeble median carina, elsewhere shining and with minute punctures. Scape short, inserted much nearer base than apex of rostrum. Prothorax moderately transverse, sides strongly rounded; punctures normally concealed; with eight con- spicuous fascicles in two transverse series. Scutellwm round and distinct. LHlytra ovate-cordate, base strongly trisinuate, sides strongly rounded; with rows of large partially-concealed punctures, in rather narrow striz; third, fifth, and seventh interstices with rather loosely-compacted fascicles. Abdomen with basal segment rather strongly convex, intercoxal process with a curved row of large punctures; elsewhere almost or quite impunctate. Length, 44 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1451. In general appearance something like terre-regine, but with a distinct scutellum, a character which readily dis- tinguishes it from all others of the genus. The subapical tooth of each tibia is more distinct than usual. On each elytron there is a subtriangular medio-lateral space, on which the scales (including the fascicles) are paler than elsewhere. The abdomen of the type (which is probably a female) is almost entirely glabrous, but this may be due to abrasion. The prothoracic fascicles are unusually distinct. The extreme base of the elytra when viewed from in front is seen to have a polished undulating ridge in six lobes. In basalis the lobes are four in number, but that species differs also in having a sutural fascicle, and in being without a scutellum. EXITHIUS EPHIPPIATUS, N. sp. Black; antenne and tarsi reddish. Densely clothed with large soft scales, mostly fawn-coloured, but feebly variegated with sooty ones; each elytron with a very conspicuous patch of white scales, not quite touching the side or suture. Head evenly convex; with coarse concealed punctures. Rostrum moderately thin; tip with coarse punctures, else- where concealed. Scape inserted one-third from apex of rostrum, and the length of funicle. Prothoraz distinctly transverse, sides strongly rounded, apex about half the width of base; with dense partially-concealed punctures. Scutellum small but distinct. Hlytra with shoulders rounded, sides parallel to beyond the middle; with rows of large partially- concealed punctures. Mesosternal receptacle strongly elevated. Metasternal episterna rather wide posteriorly. 264 Femora with minute teeth, scarcely traceable through clothing. Length, 44 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1455. With a conspicuous patch of white scales on the side of each elytron as in Scleropoides trianguliferus and Hyperio- soma falcatum, the patch halfway between apex of prothorax and apex of elytra. As the basal segment of its abdomen is quite flat in the middle, and the rostrum is densely clothed almost to its tip, the type is almost certainly a male. EXITHIUS OBSCURUS, N. sp. 3. Black; antenne reddish. Densely clothed with ferruginous scales, feebly variegated with somewhat paler and sooty ones. Prothorax with six very feeble fascicles. elytra with numerous more distinct ones. Head rather strongly convex, forehead feebly trisinuate ; with dense punctures, partially concealed between eyes. Rostrum rather long, sides almost parallel, lightly notched on each side of base; with dense punctures, coarse and partially concealed on basal half, smaller and clearly defined in front. Scape inserted about three-sevenths from apex of rostrum. Prothorar moderately transverse, sides strongly rounded, apex half the width of middle; with dense partially- concealed punctures; with a very feeble median carina or impunctate line. Hlytra rather robust, sides almost parallel to beyond the middle, base moderately trisinuate; with rows of large partially-concealed punctures; second to seventh interstices with feeble tubercular swellings, supporting rather feeble fascicles. J/esosternal receptacle moderately, but not suddenly, elevated in front. Metasternal - episterna of moderate width. Memora stout, strongly dentate; tibie bisinuate on lower-surface. Length, 53-6 mm. Q. Differs in having the rostrum smoother, with sparser and smaller punctures and less of the base clothed; the basal segment of abdomen also is gently convex instead of flat in middle. Hab.—Victorian Alps (Blackburn’s collection); Tas- mania: Huon River, in tussocks (A. M. Lea). Type, I. 1456. At first glance somewhat resembling musculus, but with- out the conspicuously produced shoulders of that species; simulator has more parallel-sided elytra and mesosternal receptacle suddenly elevated. EXITHIUS OBLIQUUS, N. sp. Blackish-brown; legs, rostrum, and antennz reddish. Densely clothed with large, soft, fawn-coloured scales, feebly 265 variegated with paler and darker ones. Prothorax with six fascicles, elytra with many small and a few large ones. Head moderately convex; punctures normally concealed. Rostrum moderately long, sides incurved to middle, very feebly notched on each side of base; basal third with coarse partially-concealed punctures, elsewhere with smaller but clearly-defined ones. Scape inserted almost in middle of rostrum, scarcely half the length of funicle and club com- bined. Prothorax strongly transverse, sides strongly rcunded, apex less than half the width of middle; punctures normally concealed. Elytra with sides lightly dilated to beyond the middle, and then rather strongly narrowed to apex, base trisinuate; with rows of large almost-concealed punctures; third interstice with an elongated tubercle near base, the second with a somewhat smaller one at summit of posterior declivity, elsewhere with small rounded tubercles. Meso- sternal receptacle suddenly elevated in front. Metasternal episterna rather narrow. Basal segment of abdomen moderately convex, its suture with second almost straight. Femora rather stout, feebly dentate. Length, 33 mm. Hab.—Victoria (Blackburn’s collection). Type, I. 1457. At a glance something like conjwnctus, but fascicles dif- ferently disposed, and the two at summit of posterior declivity distinctly separated; the mesosternal receptacle is also more suddenly elevated, and its base is decidedly larger. On the prothorax there is a feeble dark oblique stripe on each side of the base. On the elytra there is a feeble pale oblique patch from each shoulder to near the suture. Some of the fascicles are composed of black scales. The third interstice has an elongated fascicle, supported by a tubercle, near the base, its apex feebly connected with a smaller one on the second; the second has a fairly large fascicle at summit of the declivity, appearing to mark the end of an oblique row of smaller fascicles that extend to the seventh interstice; and on the posterior half of the elytra there are many other small fascicles. | EXITHIUS TROPIDOPTERUS, n. sp. Black; antenne and tarsi of a rather bright-red. Densely clothed with scales mostly of a dingy-brown or sooty. Prothorax with six feeble fascicles, elytra with more. Head with dense punctures, concealed in front; forehead trisinuate. Rostrum rather wide, sides distinctly incurved to middle; with fairly large and rather dense punctures, clearly defined except at base, where they are coarser and partially concealed; with a feeble, impunctate median line. Scape inserted slightly closer to base than to apex of rostrum, the length of three following joints combined. Prothoraz rather 266 strongly transverse, basal two-thirds almost parallel-sided ; punctures normally concealed; with a feeble median carina. Elytra with sides feebly and irregularly dilated to apical third, then strongly and irregularly narrowed to apex, base trisinuate; with irregular rows of large partially-concealed punctures; suture with a conjoint tubercle halfway down posterior declivity; each elytron produced at apex, and each with a strong and rather wide curved ridge, commencing at the second interstice at about the middle and terminated at the side, where it is suddenly narrowed. Mesosternal receptacle strongly elevated. Metasternal episterna narrow, but frontal triangle large and distinct. Basal segment of abdomen moderately convex, its suture with second rather feeble and curved in middle, but deep at sides. Memora stout, very feebly dentate. Length, 4-41 mm. Hab.—Victorian Alps (Blackburn’s collection). Type, I. 1458. The femoral dentition is extremely feeble and is quite concealed from most directions. The elytra are much as in cartosus, but the prothorax is very different. The conspicuous slightly curved ridges at the summit of the posterior declivity should prevent it from being confused with any other species. One of the types (they are probably both females) is rather badly abraded, but the other is evidently in good condition. The latter has the clothing of the under-surface moderately variegated, on the elytra its posterior declivity is mostly clothed with sooty scales; on its prothorax there is a some- what dingy patch of pale scales across the middle and feebly connected with the middle of the base. EXITHIUS AUCHMERESTHES, Nl. Sp. Black; antenne and tarsi reddish. Densely clothed with scales varying from a dingy-fawn or brown to sooty- Prothorax with six fascicles, elytra with more. Head with normally-concealed punctures; forehead tri- sinuate. Rostrum moderately stout, sides lightly incurved to middle; with dense and coarse punctures, partially concealed about base. Scape inserted in middle of rostrum, the length of three following joints combined. Prothorax moderately transverse, sides moderately rounded; punctures normally concealed. Hlytra rather elongate, sides feebly rounded, base trisinuate, shoulders prominent; with rows of large partially- concealed punctures; each with three rather large fasciculated tubercles in line with suture, fifth and seventh interstices with some smaller ones; suture with a few granules near base. Mesosternal receptacle strongly elevated. Metasternal episterna very narrow. JTemora stout, edentate. Length, 4 mm. 267 Hab.—Victorian Alps (Blackburn’s collection). Type, {. 1459. In appearance fairly close to the typical form of con- spiciendus, but femora edentate. Much the build of obliquus, but femora and clothing different. The three conspicuous tubercles on each elytron in line with the suture are probably all on the third interstice, but the type being unique it has not been abraded to make certain of this. As the basal segment of its abdomen is distinctly depressed in the middle it is probably a male. ATHYREOCIS, 0. g. Head comparatively large, convex, partly concealed from above. Hyes feebly produced in front, widely separated, coarsely faceted. Rostrum rather short and wide, sides lightly but distinctly incurved to middle. Scape inserted nearer base than apex of rostrum, much shorter than funicle ; funicle with two basal joints elongate; club briefly ovate. Prothoraz lightly transverse, sides rounded, apex produced. Scutellum apparently absent. SHlytra closely applied to and but little wider than prothorax, base trisinuate. Pectoral canal deep and wide, terminated between middle coxe. Meso- sternal receptacle feebly raised, emargination widely trans- verse, cavernous. Metasternum very short; episterna narrow in middle but traceable throughout, or indistinct. Abdomen large; two basal segments large, the suture between them curved, second shorter than first, but longer than third and fourth combined. JLegs rather long and thin; femora not at all or very feebly grooved, feebly or not at all dentate; tibize scarcely compressed, the front ones feebly bisinuate on lower- surface. Allied to Hazithius, but scutellum absent, head evenly convex, and abdominal sutures distinct. The clothing is very dense, and scattered amongst the adpressed scales are numer- ous stiff erect ones, in places compacted into feeble fascicles. The hind femora when placed in a line with the abdomen extend to or just pass the tip of the elytra, except on albonotatus; on one specimen of tarsalis they all appear to be very feebly dentate, but this appearance may simply be due to feeble clusters of scales; on the four hind femora of tibialis, however, teeth are certainly present. I was at first inclined to regard the five species here described as belonging to two genera, but as the only generic features in which they differ are the metasternal episterna and the femora, and the points of difference are only noticeable with difficulty, it was considered advisable to treat them as belonging to but one genus. In all the species there are dense round punctures on 268 the head and prothorax, but these are normally quite con- cealed; there are also rather dense punctures on the under- surface, some of which can be traced before abrasion. Metasternal episterna not traceable throughout. Claw-joint with stout erect scales ... tarsalis Claw-joint at most finely setose ... echinatus Metasternal episterna traceable through- out. Four hind femora dentate... ... ... tibialis Femora edentate. Elytra with whitish scales ie posterior declivity . tigi albonotatus Elytra without such scales cee nigronotatus ATHYREOCIS TARSALIS, n. sp. Black; antennz and tarsi reddish. Very densely clothed with muddy-brown scales (muddy-grey on under-surface), interspersed with numerous erect, stout ones, frequently sooty, and in places compacted into fascicles. Rostrum lightly curved, scarcely as long as prothorax; basal third with coarse concealed punctures, elsewhere shining and with small but clearly-defined ones. Prothorax somewhat uneven. “lytra about twice as long as wide, almost parallel- sided to middle; with rows of large punctures normally almost, or quite, concealed. Metasternal episterna not trace- able throughout. Hind femora extending to tip of elytra. Length, 34-34 mm. os Hab.—Queensland: Cairns district (A. M. Lea); Kuranda (G. E. Bryant). Type, I. 1511. There are two distinct fascicles on the third interstice of each elytron: one at basal third, the other beyond the middle ; on the prothorax there are four feeble ones across the middle. Each of the three typical specimens, when viewed from behind, appears to have a small dark spot on each side of the base of the prothorax; from directly above the spots are less distinct, and from in front they are invisible. The erect scales are very conspicuous on the legs, and a few are present even on the claw joint of each tarsus. ATHYREOCIS ECHINATUS, N. sp. Reddish-brown; antennz and tarsi somewhat paler. Densely clothed with muddy-brown scales, thickly interspersed with stout erect (and mostly sooty) ones, in places compacted into fascicles. Rostrum moderately curved, about as long as prothorax, basal fourth with concealed punctures, elsewhere highly polished and with small clearly-defined ones. Prothorax 269 almost evenly convex. lytra feebly dilated from base to beyond the middle, and then rounded to apex; with rows of large, normally almost, or quite, concealed punctures. Metasternal episterna not traceable throughout. Femora — edentate, hind pair just passing tip of elytra. Length, “34 mm. : Hab.—Queensland: Cairns district (A. M. Lea.) Type, Pe 1512. The derm of the type, which is probably a female, is as described, but it is probable that it is sometimes black. The clothing is much as on the preceding species, but the claw joint is entirely without stout scales, although there are a few on some of the other tarsal joints. On the prothorax there are four feeble fascicles across the middle, and two at apex. On the elytra there is an elongated loose fascicle on the third interstice, at about the basal third, and a feeble one beyond the middle; from some directions the two appear to be feebly connected. ATHYREOCIS TIBIALIS, n. sp. 3. Of a dingy dark-brown, sometimes almost black; antenne and tarsi red. Densely clothed with muddy-grey scales, feebly variegated on elytra; interspersed with stout, erect scales, in places compacted into fascicles. Rostrum lightly curved, scarcely as long as prothorax; basal third with coarse concealed punctures, elsewhere shining and with dense and comparatively coarse ones except along the middle. Prothorax evenly convex. Jlytra elongate- subcordate, sides feebly rounded; with rows of rather large _ punctures in striz, only the strie normally visible. Meta- sternal episterna traceable throughout. Femora feebly dentate, hind pair not quite extending to apex of elytra; middle tibie angularly dilated at the external middle. Length, 24-22 mm. @. Differs in having the rostrum slightly longer, with smaller punctures, and middle tibie not angularly dilated and dentate at the external middle. Hab.—Queensland: Mount Tambourine (A. M. Lea). Pype, I. 1513. In general appearance close to the following species, but four hind femora dentate as well as grooved. The teeth are certainly small, but they are quite distinct from some direc- tions. The front femora are also dentate, but the teeth are extremely minute, invisible from most directions and normally concealed by clothing. On the elytra there are remnants of two very feeble pale fasciz, one across basal third and one at summit of posterior declivity. They appear fairly distinct on account of the feeble dark fascicles on the third interstice ; 270 these are situated at the basal fourth and about the middle. On the prothorax the erect scales are rather numerous, but they are not compacted into fascicles, or at least not into distinct ones. Most of the erect scales are more or less sooty, but on the legs they are mostly whitish. The middle tibiz of the male are peculiar, but their outlines are somewhat obscured by the clothing, although in certain lights very distinct. ATHYREOCIS ALBONOTATUS, Nn. sp. Black, in parts diluted with red; antenne and tarsi reddish. Densely clothed with somewhat variegated scales, thickly interspersed with stout erect ones, mostly sooty on upper-surface,-mostly whitish on legs. Head and rostrum much as in preceding species; pro- thorax and elytra much the same. Metasternal episterna narrow in middle but traceable throughout. Femora edentate, hind pair not quite extending to tip of elytra. Length, 21-25 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1514. In general appearance close to Achopera parva, but meta- sternum distinctly shorter than the following segment. On the type the clothing is evidently in perfect condition, and is mostly of a pale muddy-brown or fawn-colour (paler on the under-surface). On the prothorax there is a feeble sooty spot on each side of the base, on the elytra there are several feeble sooty spots, and some distinct white ones, the latter are near the suture on the basal third, and irregularly crown the pos- terior declivity, where they form a somewhat V-shaped pattern on each elytron. On two other specimens the sooty and white markings are traceable, but are much less distinct ; the summit of the posterior declivity being crowned with feeble spots, not forming V’s. The stout scales, although numerous, nowhere form distinct fascicles. The grooves on the femora are seen with difficulty, and on the front pair are extremely faint. ATHYREOCIS NIGRONOTATUS, N. Sp. 3. Blackish-brown; antenne and tarsi reddish. Densely clothed with somewhat muddy-brown scales thickly interspersed with stout erect and usually sooty ones, in places condensed into fascicles. Under-surface with paler scales than on upper-surface. Rostrum rather lightly curved, scarcely the length of prothorax, basal third with concealed punctures; elsewhere shining, and, except for a narrow line along middle, with 271 dense and rather coarse ones. JProthoraz rather lightly convex. Llytra feebly dilated to beyond the middle, and then distinctly narrowed to apex; with rows of moderately large ‘punctures in deep striz, the punctures normally almost con- cealed, but the striz moderately distinct. Metasternal episterna narrow in middle, but traceable throughout. Femora edentate, feebly grooved, especially the front pair, hind ones almost extending to apex of elytra. Length, 21-22 mm. Differs in having the rostrum slightly longer and thinner, less of the base clothed, and elsewhere more polished and with smaller and sparser punctures. Hab.—Queensland: Mount Tambourine (A. M. Lea). Bye: 1515. On the prothorax there is a rather large obscure sooty patch on each side of the base. On the third interstice of each elytron there are two rather distinct fascicles: a fairly elongate one at basal third, and a smaller one beyond the middle; from the hind margin of the subbasal fascicle to the shoulder there is an indistinct stripe of pale scales. On the prothorax the stout scales on one specimen form very feeble fascicles across the middle, but on three others no fascicles can be traced there. One specimen has the entire derm of a rather pale-red, but this may be due to immaturity; it has also traces of a second oblique fascia beyond the middle. TRIPTOCIS, n. g. Head of moderate size, base shining and impunctate. Eyes rather small, widely separated, coarsely faceted. Rostrum moderately long and not very thin, lightly curved. Antenne moderately thin, scape inserted nearer apex than base of rostrum, and the length of funicle, two basal joints of funicle moderately long, the others very short, club subovate. Pro- thorax transverse, sides rounded, base truncate. Scutellum absent. Hlytra widest near base, thence decreasing to apex, base truncate. Pectoral canal deep and wide, terminated between middle coxe. Mesosternal receptacle strongly and suddenly elevated, base strongly keeled, emargination strongly transverse; cavernous. Metasternum very short; episterna very thin. Abdomen large, first segment as long as three fol- lowing combined, its apex almost straight, second as long as third and fourth combined. Legs moderately long; femora grooved and dentate ; tibiz compressed and moderately curved ; tarsi thin. | The polished forehead and very short metasternum indi- cate that this genus is allied to Poropterus. The metasternal episterna are extremely narrow, with the inner suture of each 272 very feebly impressed, and the hind tip disappearing under the elytra, so that in an (at present manuscript) table of the allies of Poropterus, it would be associated with Gymnoporopterus, to which in fact it appears to be close, but from which it differs in its dentate femora and more rounded eyes, with decidedly coarser facets. TRIPTOCIS PUNCTICOLLIS, Nn. sp. Black, in places feebly diluted with red; sides of elytra with a bluish gloss; antennz and tarsi red. Prothorax with a few whitish scales on sides, elsewhere almost glabrous; elytra with greyish scales in sutural region. Legs moderately densely, the under-surface more sparsely, clothed. Head with dense and coarse punctures in front, elsewhere polished and without distinct punctures. Rostrum about as long as front femora, sides very feebly increasing in width to apex; near base with coarse punctures, elsewhere with much smaller but distinct ones; with a narrow median line on basal two-thirds. Prothorar moderately transverse, apex more than half the width of middle; with dense and rather coarse, clearly-defined punctures. /lytra strongly convex, subcordate, sides oblique from base to basal fourth, thence rapidly decreasing in width to apex; each with three rows of fairly large punctures in distinct strie towards suture; elsewhere with smaller and more distant punctures, in very feeble striz. Under-surface with rather coarse punctures. Legs coarsely punctured ; front femora feebly grooved and feebly dentate, the others more distinctly grooved and moderately dentate. Length, 21 mm. Hab.—Queensland: Mount Tambourine, from rotting leaves (A. M. Lea). Type, I. 1519. The major portion of the side of each elytron appears to be normally glabrous and highly polished, with a distinct steely-blue gloss; the sutural portion is moderately clothed for a space extending to about three interstices from the suture itself, and is of a dingy-red, with distinct rows of punctures. ANCHITHYRUS RETICULATUS, Lea. The type of this species is a small male. I have recently _ taken nine specimens in the Cairns district ranging in length from 32 to 44 mm. Although generally black, the derm is sometimes of a dark reddish-brown. The male has the rostrum with sides distinctly incurved to middle, and antennz inserted almost in exact middle; its basal half has coarse but more or less concealed punctures. The female has rostrum longer, some- what thinner, with coarse punctures only near base, elsewhere shining, and with rather small but clearly-defined punctures ; the sides at the basal third are almost parallel, but thence 273 feebly dilate to apex; the antennz are inserted distinctly nearer base than apex. IMALIODES LONGIPES, 0. sp. 3. Black, in parts diluted with red. Densely clothed with ashen-grey scales, in places thickly interspersed with stout suberect ones. Head with dense concealed punctures. Eyes rather finely faceted. Rostrum moderately long, not very stout, somewhat dilated in front, apical third with dense punctures, concealed elsewhere. Antenne rather thin; scape inserted one-third from apex of rostrum, as long as funicle; two basal joints of funicle subequal in length. Prothorar about as long as wide, sides evenly rounded, apex not much narrower than base; with dense and rather shallow, concealed punctures. Sewtellum absent. Hlytra ovate, strongly convex, each separately rounded or almost truncate at base, base no wider than pro- thorax, but sides strongly rounded; with rows of very large punctures, becoming smaller posteriorly; non-tuberculate. “Third and fourth segments of abdomen level with second and fifth. Legs long; femora moderately stout, edentate, scarcely grooved, hind pair distinctly passing elytra. Length, 54-6 mm. Q. Differs in having the rostrum somewhat longer, punc- tures concealed only at base, elsewhere shining and with numerous rather small, clearly-defined punctures; scape inserted not quite so close to apex of rostrum; and basal seg- ment of abdomen feebly convex in middle instead of flat. Hab.—Queensland: Mount Tambourine (H. J. Carter and A. M. Lea); New South Wales: Tweed River (H. W. Brown). Type, I. 1547. The edentate femora associate this species with frater, from which it is distinguished by the non-fasciate elytra. The legs are much longer than those of ovipennis, and the hind femora distinctly pass the elytra. In the elytra and long legs this and the following species resemble Anchithyrus, but the eyes are finely faceted. From some directions the first joint of funicle appears to be a trifle shorter than the second, but it really is of exactly the same length. IMALIODES BINODOSUS, 0. sp. 2. Blackish; antennz and tarsi obscurely reddish, Densely clothed with muddy-brown scales, somewhat paler on under- than upper-surface. With numerous stout scales inter- spersed. : Head with concealed punctures. Eyes rather large and with fine facets. Rostrum moderately long, rather wide at 274 base, narrowed to antennz, and then parallel-sided to apex; about base subopaque and with coarse punctures, elsewhere shining and with minute ones. Scape inserted about two-fifths from base of rostrum, distinctly shorter than funicle; first joint of funicle slightly longer than second. Prothorax lightly transverse, sides gently rounded; with very dense, concealed punctures. Scutellum minute. EHlytra subovate ; base almost truncate, but feebly notched at scutellum, and with shoulders very feebly produced; sides somewhat dilated to beyond the middle; with rows of large, deep punctures, becoming smaller posteriorly ; third interstice with a tubercular swelling at basal third. Third and fourth segments of abdomen level with second and fifth. Legs rather long; femora not grooved, scarcely visibly dentate, hind pair passing tip of elytra. Length, 5 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1548. In some respects close to edentatus, but with considerably longer legs. In these resembling ovipennis, but differing from that species (as also from the preceding one) in the bitubercu- late elytra and presence of a scutellum. The femoral teeth are very minute, and scarcely visible through the clothing. IMALIODES LATIPENNIS, n. sp. Black; antennze and tarsi red. Densely clothed with rusty-brown scales; thickly interspersed with stout suberect ones. Under-surface with somewhat paler, and even denser, clothing than on upper-surface. Head with concealed punctures. Eyes rather small and with coarse facets. Rostrum short and thick, with an obtuse median ridge; punctures concealed except at apex, where they are numerous. Scape short and stout, inserted one-third from base of rostrum, the length of two following joints combined ; of these the first is shorter than the second. Prothoraz moderately transverse, sides strongly rounded, apex about half the width of base; punctures concealed. Scutellum absent. Elytra scarcely longer than wide, strongly convex, base lightly trisinuate, shoulders very feebly produced, sides strongly rounded; with rows of very large punctures; non- tuberculate. Mesosternal receptacle more strongly elevated than usual. Third and fourth segments of abdomen depressed below others. Legs short; femora stout, distinctly grooved, edentate, terminated before apex of abdomen. Length, 44 mm. | Hab.—Queensland: Mount Tambourine, from rotting leaves (A. M. Lea). Type, I. 1549. 275 A very short, compact species, allied to swhfasciatus, but smaller, scape shorter and inserted nearer base than apex of rostrum; edentatus is about the same length, and has similar clothing on the upper-surface, but its antenne are inserted at a slightly different position, and its elytra are much narrower. The clothing on the under-surface is unusually dense, and on the type (which is probably a male) is matted together by dirt or by an exudate; but across the second segment a closely-set mass of pale scales, like a transverse fascia, is very conspicuous, on the first segment also a similar mass of scales, but incurved at the middle, can be traced. Probably, however, the clothing is sexually variable. Emypica. (13) Dr. Gestro sent a specimen as Hmydica platynota, Pasc., labelled as having been taken by Beccari at Ansus, in New Guinea (the original collector and locality). It might, there- fore, fairly be regarded as a co-type. The specimen has a small but distinct fasciculate tubercle, at about the apical fourth, on the fifth interstice of each elytron. The sides of its pro- thorax and elytra are margined with closely-set scales pro- jected outwards, so that the margins appear to be more acute than they really are. The whole of its upper-surface is clothed with muddy-grey scales. The original figure (pl. ii., fig. 1) is a very poor one, and gives a misleading idea of the species. In catalogues the genus should be placed near Imalithus, whose only known species is also greatly depressed. The genus referred to here as an Australian species is now to be described. EMYDICA BREVISETOSA, 0. sp. 6. Reddish-brown; antenne and tarsi red. Rather densely clothed with white or whitish scales, variegated in places (and especially on elytra) with pale-brown ones. Fifth interstice on each elytron with a narrow fascicle at the apical third. Margins with a closely set fringe of stout, slightly variegated, brownish scales. Upper-surface with short, up- right, and rather dense sete. Front tibiz and tarsi fringed beneath with long and almost golden setz. Head with dense concealed punctures. Rostrum almost as long as prothorax, lightly curved, moderately wide at base but narrowed to antennz, thence almost parallel-sided; with very dense and rather coarse punctures concealed on basal half. Prothorax very flat, about once and one-half as wide as long, sides gently rounded, apex trilobed, median lobe about one-third the width of base; with rather small punctures. Scutellwm small but distinct. Hlytra flattened, slightly wider than prothorax, almost parallel-sided to near (13) Pascoe, Ann. Mus. Civ. Gen., 1885, p. O55. 276 apex; with eight rows of distinct punctures between suture and each side; interstices about twice the width of punctures. Under-surface with more or less concealed punctures. /emora conspicuously grooved and edentate. Length, 6 mm. @. Differs in having the rostrum longer and thinner, punctures concealed only about basal fourth, and elsewhere very small, although usually clearly defined. Antenne in- serted nearer base than apex of rostrum, instead of in exact middle. Abdomen more convex, and front legs with normal clothing. : Hab.—Queensland: Cairns district (F. P. Dodd); Cook- town (H. W. Brown). Type, I. 1520. With outlines much as in platynota, but with larger, sparser, and less depressed scales, and in addition with numer- ous short erect sete; these are very distinct from the sides, but almost invisible from above. The lateral fringes of the prothorax and elytra are also more conspicuous, and the fringes on the front tibiz of the male are shorter and more compact. The scales on the under-surface are closely applied to the derm, and have the usual laminated appearance, but on the upper-surface they all have a curiously rough, sub- granular appearance. The legs have feeble brownish rings or blotches. PLATYTENES. (14) This genus is remarkably distinct on account of the large finely-faceted eyes, thin rostrum, very short scape (which is inserted almost at base of rostrum), and large scutellum; but in particular by the metasternal episterna. These, instead of running level with the sides of the elytra, as in all other (at least Australian) genera of the subfamily, semicircularly encroach upon them from near the base to almost level with the hind coxe. In the original description Pascoe referred it to the Cryptorhynchides vrais, but stated that it was 1m- possible ‘‘to approximate it to any known genus.’’ Subse- quently, in recording it from New Guinea, he placed it next to Perissops. I think, however, that on account of its thin rostrum and comparatively long metasternum, with large episterna, it is perhaps better regarded as being one of the (not very close) allies of Chetectetorus. PLATYTENES VARIUS, Pasc.(5) This curious weevil can now be recorded as Australian, as a specimen was in the collection of the late Rev. T. Black- burn, labelled as having been sent by Mr. French from (14) Pascoe, Journ. Linn. Soc., x., 1869, p. 466. (15) ZL. c., p. 467, pl. xviii., fig. 1; Ann. Mus. Civ. Gen., 1885, pe Zod: 277 North Queensland. It is widely distributed in the Malay Archipelago and New Guinea. Pascoe described the typical specimens as variable, and the three specimens before me (from Queensland, the Fly River,“ and Aru) are all some- what different in clothing; but they agree in having four small dark fascicles (placed as it were each at the corner of a small square) at the apex of the prothorax; and a distinct patch of whitish scales at the apex of the elytra, and another on each side near the middle. The original figure is somewhat misleading, as the insect is made to appear rather strongly convex, instead of which it is unusually flat, and in fact feebly concave along the middle; the figure (1b) of the under- surface, however, is more satisfactory: BRACHYCIS, 0. g. Head rather small, concealed from above. Eyes moderately large, finely faceted. Rostrum long and thin, feebly curved. Antennz thin; scape inserted about middle of rostrum, the length of funicle; two basal joints of funicle elongate, the others transverse; club elongate-elliptic, sutures oblique. VProthorax strongly transverse. Scutellwm distinct. Elytra scarcely longer than wide, base closely applied to pro- thorax and no wider than same. Pectoral canal deep, ter- minated between middle coxze. Mesosternum composed of four pieces on each side between cox and elytra; receptacle depressed on each side, but middle raised, cavernous, and with U-shaped walls. Metasternum almost as long as the following segment; episterna wide. Abdomen with two basal segments large, first almost as long as second to fourth com- bined. Legs rather short; femora stout, strongly dentate; tibis compressed. Squamose, tuberculate, winged. An extraordinary genus of doubtful affinities, but the rather long metasternum, with wide episterna, and long and but feebly curved rostrum seem to associate it with the allies of Chetectetorus, perhaps near Huthyrrhinus, although the elytra are not mucronate. In the table of genera allied to Chetectetorus 27) it would be associated with Pseudometyrus, with which, however, it has but little in common. The cloth- ing normally partially conceals the side pieces of the meso- sternum, but on two of the specimens before me their sutures are distinct; starting from the coxa the first appears to be irregularly four-sided, but its front curves round the coxa till it meets the receptacle, the second is a triangle, the third is irregularly four-sided, but at first appears to be a triangle with its apex cut off at the metasternum; the fourth is also four-sided, but is wider than long. by) (16) From Dr. Gestro. (17) Proc. Linn. Soc., N.S.W., 1909, pp. 594-595. 278 BRACHYCIS THORACICUS, N. Sp. Blackish; antennz and tarsi obscurely reddish. Densely clothed with very paie-brown or fawn-coloured scales, becom- ing darker on posterior half of elytra, and on a large oval median space on prothorax. Scales of under-surface of body and of legs mostly whitish. Head with punctures normally concealed. Rostrum slightly longer than prothorax, sides dilated about base, but almost parallel elsewhere; sides about base with coarse partially-concealed punctures, in middle of base feebly ridged ; elsewhere with small but clearly-defined punctures. Pro- thorax twice as wide as long, middle with a wide depression, bounded in front by a conspicuous semicircular ridge, between each side of the ridge and the margins strongly bisinuate ; with very dense and small normally-concealed punctures. Hlytra not much wider than long, base the width of base of prothorax, and somewhat sinuous, parallel-sided to about the middle, and then widely rounded; with rows of rather small partially-concealed punctures; suture rather strongly elevated and granulate in middle, third interstice with two elongated tubercles, one about basal third, the other submedian, fourth with a feeble swelling midway between the two on third, fifth with a rather strong one at about basal third; elsewhere with a few slight swellings, posterior declivity long and abrupt. Under-surface with dense punctures. Length, 6-8 mm. Hab.—Australia (Blackburn’s collection); Queensland : Darling Downs (C. French) ; Mount Tambourine (R. Illidge). Type, I. 1480. From above the prothorax appears to have a wide median lobe overhanging the head, with a smaller lobe on each side between it and the margin. From in front the apical sides appear to be cut away with three obtuse tubercles bounding the hind portion of each excavation. In Mr. H. Hacker’s private collection (now in the Berlin Museum) there was a specimen of this species with subopaque and finely-carinated rostrum; it is probably a male, in which case the three typical specimens are probably females. Commander J. J. Walker had a specimen from Mittagong (New South Wales) much smaller and darker than the types. ODOSYLLIS SCUTELLARIS, Nn. sp. Black; antennz and tarsi more or less reddish. Densely clothed with ochreous-brown scales, variegated with small obscure spots of sooty and of whitish ones. Head with coarse punctures and a few shining granules. Rostrum moderately long, sides distinctly inflated towards, 279 but notched at base; basal half with coarse crowded punctures, apical half with sparser and much smaller ones. Scape inserted about two-fifths from apex of rostrum; two basal joints of funicle moderately long and subequal. Pro- thorax strongly transverse, apex about one-third the width of base; with dense concealed punctures; with numerous small granules, each with a setiferous puncture in front. Scutellum conspicuously elevated, each side densely clothed. Elytra not much wider than prothorax, sides almost parallel to beyond the middle, and then strongly narrowed to apex, which is conjointly mucronate; with rows of moderately large punctures in distinct strie; interstices with numerous small, shining granules, mostly in rows, but irregular on basal half of the third, and somewhat crowded on a raised space near base. ,Under-surface with dense punctures. Legs moderately long; hind femora lightly, middle moderately, front strongly dentate. Length, 12 mm. Hab.—Queensland: Cairns district (F. P. Dodd). Type, T. 1525. The acutely-elevated scutellum readily distinguishes from erucigera, the only previously described Australian species. The figure of zngens 8) will give a good general idea of this species, except that the legs of the figure are rather longer. That species also is described as having an elevated scutellum, but its clothing is very different and its under-surface is densely granulate. It is perhaps also close to the briefly- described gemmata, but that species is said to be larger (15 mm.) and with the elytral punctures almost obsolete. Most of the elytral tubercles are obscurely diluted with red. The scales are larger on the abdomen and sides of sterna than elsewhere, but they are almost as large on the pronotum. On the prothorax there are five small pale spots equi-distant across the middle; on the elytra the pale spots are very feeble and few in number; but the sooty ones are more numerous, the more distinct ones being at the summit of the posterior declivity, on the fourth interstice at base, and on the third near apex. The sex of the type is doubtful; the punctures of the rostrum appear to be of a masculine nature, but the front tibie have but a few short sete on the apical half, very different to the conspicuous fringes of the males of other species. ISAX PLANIPENNIS, Lea. A female from Dorrigo, in Dr. Ferguson’s collection, differs from the types in having numerous black setose scales (18) Ann. Mus. Civ. Gen., 1885, pl. ii., fig. 8. 280 scattered amongst the paler ones on the prothorax. On two specimens from Mount Tambourine the prothoracic clothing is similar, but each elytron has two distinct spots of reddish- ochreous scales, one on the shoulder and one on the fourth interstice near apex ; similar scales clothe the sides of the meta- sternum, and are fairly numerous on the sides of the abdomen. On several other specimens remnants of similarly-coloured patches are present, and their absence is probably due either to abrasion or to staining. PHLHOGLYMMA MIXTA, Lea. Two specimens from Quorn appear to represent a variety of this species; they differ from the types in being smaller (5-54 mm.), with the fascicles and patches of dark scales less sharply defined. One was labelled ‘‘Huorogis?’’ by the late Rev. T. Blackburn, and it certainly has tibie angularly dentate at the outer base; the only character given by Pascoe in separ- ating Hworopis from Acalles. But whilst the species certainly belongs to Phleoglymna, almost certainly it does not belong to Hworopis, the described sculpture of 1’. castanea seeming to denote that it really is, as stated, allied to Acalles; whilst Phleoglymna belongs to the widely separated Chetectetorus group. EPHYRCUS MINOR, N. sp. Reddish-brown, in parts almost or quite black; antennz (club infuscate) and tarsi reddish. Densely clothed with scales, varying from mostly pale to mostly sooty. With some stout, suberect ones scattered about. Head with dense, concealed punctures. Rostrum not very thin; shining and with minute punctures, concealed only close to base. Scape inserted about one-third from base of rostrum, scarcely half the length of funicle and club combined; club large. Prothorax lightly transverse, base truncate and less than twice the width of apex ; with dense, concealed punctures. Hlytra not much wider than prothorax, and more than twice as long, sides parallel to beyond the middle; with rows of large, almost-concealed punctures; second interstice with a feeble fascicle near middle, and third with one near base, very feeble ones elsewhere. Under-surface with rather numerous, partially-concealed punctures. Length, 13-2 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, Sl). Close to parvus, but even smaller than that species and with very feeble fascicles. |The four typical specimens are apparently of one sex. On the prothorax most of the scales are pale, but on one specimen they are mostly dark, but with a conspicuous patch of pale ones on each hind angle. There 281 are four very feeble fascicles of dark scales across middle and two at apex. On the elytra most of the scales are greyish, but with obscure sooty spots, and a vague, sooty, median fascia, sometimes broken up into spots. The stout scales are fre- quently of a snowy whiteness, but the majority are sooty. On the head, except in front, the scales are mostly sooty. ACHOPERA BIFASCIATA, DN. Sp. ~*~ ¢. Reddish- brown, in parts somewhat obscured ; antenne and tarsi red. Densely clothed with greyish scales, variegated with paler and darker ones; with some stout sub- erect scales scattered about, but not forming fascicles. Head with dense, round, concealed punctures. Rostrum rather short and wide; punctures concealed throughout. Scape inserted slightly nearer base than apex of rostrum. Prothorar lightly transverse, feebly convex; with dense, round, concealed punctures. Llytra about one-fourth wider than prothorax, parallel-sided to near apex; with rows of large, almost, or quite, concealed punctures; striation distinct through clothing. Under-surface with dense concealed punc- tures. Basal segment of abdomen widely and feebly concave in middle. Length, 3-34 mm. Q. Differs in having rostrum slightly longer, apical half with sparser clothing, so that some of the punctures are visible ; scape inserted distinctly nearer the base of rostrum, and basal segment of abdomen gently convex throughout. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1534. In general appearance fairly close to maculata, but smaller, and elytra bifasciate. On the type male the scales on the under-surface and legs are almost white, but each femur has a more or less distinct sooty patch. On the upper-surface most of the scales are of a light slaty-grey. On the elytra there are two distinct and somewhat curved, or oblique, pale fasciz : one across basal third, rendered more distinct by some sooty spots about it; and one across summit of posterior declivity. On each side the former terminates on the shoulder and the latter at the middle. The prothorax has a medio-basal obscure spot, and about the middle a few small pale ones. On the female the scales are less distinctly variegated, most of them being of a darker slaty-grey than on the male, and the fasciz are ill-defined, although traceable. ACHOPERA PARVA, Nl. Sp. Reddish - brown; antenne and tarsi paler. Densely clothed with greyish scales, variegated with patches of darker ones; with stout suberect scales scattered about. 282 Head with concealed punctures. Eyes rather small. Ros- trum moderately long, feebly curved, very feebly dilated from base to apex; basal half with concealed sculpture, elsewhere shining and with minute punctures. Scape inserted about one-third from base of rostrum. Prothorax about as long as wide, moderately convex, sides somewhat rounded; with dense, round, concealed punctures. Elytra about one-third wider than prothorax, sides almost parallel to beyond the middle; with rows of large, almost, or quite, concealed punc- tures. Metasternum distinctly longer than the following seg- ment; the latter flat in middle. Claw-joint unusually long. Length, 2 mm. Hab.-——Queensland: Cairns district (A. M. Lea). Type, I. 1535. In the table of genera allied to Chetectetorus'9) would be associated with Menzos, from which it is at once distinguished by the edentate femora. The prothorax is less depressed than is usual in Achopera, but as that appears to be the only dis- crepancy it was referred to that genus. It is the smallest of the genus, and, except for some minute species of HL phrycus, the smallest of all the Australian members of the Chetecte- torus group. The sex of the type is doubtful, the rostrum and insertion of antennz appear to denote that it is a female, but the basal segment of abdomen is quite flat in the middle. The antennze are almost flavous. On the upper-surface there are two small sooty spots at the base of the prothorax, several at base of elytra, a series across summit of posterior declivity, and a few below same; but they are all rather ill-defined. On the legs also there are some obscure sooty patches. ACHOPERA ISABELLINA, N. Sp. Dark reddish-brown, in parts almost black; antennz and tarsi reddish. Densely clothed with more or less greyish or light-brown scales. With moderately stout, subdepressed scales, more or less regularly distributed, and forming a regular row on each elytral interstice. Head rather convex; with very dense concealed punctures. Rostrum comparatively long, and rather thin, moderately curved, parallel-sided except for a slight increase in width near base; basal third with concealed sculpture, elsewhere somewhat shining, and with dense clearly-defined but rather small punctures. Scape inserted slightly nearer base than apex of rostrum, half the length of funicle and club combined. Prothoraz rather lightly transverse, some- what convex, sides strongly rounded, base strongly bisinuate ; (19) Proc. Linn. Soc., N.S.W., 1909, pp. 594-595. 283 with dense, round, concealed punctures. Hlytra about one- third wider than prothorax, base trisinuate, parallel-sided to beyond the middle, with rows of large concealed punctures ; but striation traceable through clothing. Under-surface with dense concealed punctures. Basal segment of abdomen flat in middle. Length, 6 mm. Hab.—North Queensland (Blackburn’s collection). Type, I. 1536. The largest of the genus. The tarsi are moderately densely setose on the upper-surface, the setz extending to the claw joint, the third is wide and deeply bilobed, but these characters are not sufficiently important to exclude it from Achopera. The scales are of an almost uniform colour throughout; although on each shoulder there is a large patch where they are somewhat paler than elsewhere. Except on antenne, tarsi, and parts of the rostrum they everywhere conceal the derm. But on the prothorax they are larger than elsewhere, and give it a plated appearance; each also is slightly depressed at its middle. On the abdomen also the scales have a somewhat plated appearance, although they are smaller and more overlapping than on the prothorax. The sex of the type is doubtful. ACHOPERA SABULOSA, Lea. A male from Port Lincoln differs from the types in having the large scales on the prothorax and elytra somewhat wider; but I can find no other differences. DERETIOSUS ZOPHERUS, N. sp. Dark reddish-brown, in parts almost black; antenne reddish. Very densely clothed with muddy-brown scales. With numerous stout suberect scales interspersed, and in places compacted into fascicles. Head with punctures entirely concealed. Rostrum rather long, moderately curved, sides lightly incurved to middle; punctures concealed behind antenne, but crowded in front. Antenne thin, inserted about one-third from apex of rostrum. Prothoraz moderately transverse, surface somewhat uneven; with crowded concealed punctures. Hlytra parallel- sided to beyond the middle; with rows of large, round, almost-concealed punctures; third interstice with an elongated granulated tubercle near base, and a slight swelling beyond the middle. Punctures of wnder-surface concealed. Femora strongly triangularly dentate; tibie bisinuate on lower-surface. Length, 5 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, OST: 284 On the prothorax there are four loose fascicles across the middle and two at apex. On the elytra there are several feeble fascicles, but the third interstice on each elytron of the type has been partly abraded; probably, however, the elongated tubercle near the base supported a conspicuous fascicle, and the slight swelling beyond the middle may have supported another. The clothing is very different to that of any of the previously described Australian species of the genus; and the species, in fact, quite strongly resembles Chetectetorus egenus, whose femora and mesosternum, how- ever, are very different. AGATHICIS, n. g. Hyes very finely faceted. Rostrum straight, not very long. Scape short, inserted nearer base than apex or rostrum ; club ovate, free. Prothorax feebly transverse. Other characters as in Chetectetorus. (2) In the table of genera allied to Chetectetorus 2) would be associated with Hphrycinus, with which it has little in common. ‘The species described below appears at first like a large rough Chetectetorus, and is undoubtedly close to that genus, but the facets of the eyes are unusually small. AGATHICIS DISTINCTUS, N. sp. 3. Blackish; antennz and tarsi of a dingy-red. Very densely clothed with greyish or pale greyish-brown scales, closely applied to derm; some stouter ones scattered about. Elytra with two long and very conspicuous fascicles about the middle, and some smaller ones elsewhere, as also on prothorax. Head with dense concealed punctures.

Scutellum small, but round and distinct. Hlytra very little wider than prothorax, base trisinuate, sides parallel to near apex ; with rows of large partially-concealed punctures; inter- stices, especially the third and fifth, somewhat irregular on account of small tubercular swellings supporting fascicles.

Weiske); Cairns district (A. M. Lea). Type, I. 1481. The large fascicles are on the middle of the third inter- stice of each elytron. The scales composing them are wide and thin, so that from certain directions they appear to be almost hair-like; there are other but much smaller fascicles on the posterior declivity and about the base; the extreme apex has four feeble fascicles, so that it appears to be tri- sinuate. On the prothorax there is a distinct fascicle on each side of apex, and some feeble ones across middle. There is sometimes a feeble sooty ring on each tibia. There are at least five impressions on the pronotum: a medio-basal isolated one of rather small size, a larger one on each side of middle, and a less distinct one in front of each of same; but these sometimes subconfluent; but there are also sometimes smaller depressions on the margins. The specimens from the Cairns district (seven) were taken, in company with some small bees, feeding at a resinous substance, exuding from a kauri pine {Agathis robusta) near Nelson. MENIOS. In the table of genera allied to Cheicctetorus (22) this genus was placed with those (C. C.) having the metasternum longer than the first abdominal segment; and this is certainly the case with the typical species, wternatus; but in nebulosus and albifasciatus it is a trifle shorter. MENIOS SINUATUS, Nn. sp.- 3. Reddish-brown, in parts somewhat paler. Very densely clothed with pale fawn-coloured scales, conspicuously variegated with snowy and sooty spots; with numerous stout suberect scales scattered about, and in places compacted into fascicles.

Type, Tele 82. The metasternum is just perceptibly shorter than the fol- lowing segment, and this associates the species with nebulosus and albifasciatus. The clothing on the type is evidently in perfect condition. On the head there are three white spots, and on the prothorax eight (but of the latter two on each side are not visible from above). On the elytra the white scales form an irregular fascia (wide at the suture) across summit of posterior declivity, and a few spots, mixed with sooty ones, on the middle of each side. The stout scales form very feeble fascicles on the prothorax. On each elytron they form a dis- tinct fascicle, supported by a tubercle, on the second inter- stice about the middle, and two on the third: one near base, the other beyond the middle. The three are almost in a line, and apparently on the third, but that interstice is narrowed, and curves around the fascicles on the second. This char- acter alone will readily distinguish the species from all pre- viously described ones. The third interstice is also dilated at: its two fascicles, but the sinuation of the striz adjacent to same is not quite so pronounced. The femoral dentition is also distinctive. METYRCULUS MEDIOFASCIATUS, N. sp. 3. Black; antenne and tarsi red. Densely clothed with brown and sooty scales. /Tead with dense concealed punctures. Rostrum moder- ately long, distinctly curved, almost parallel-sided: with dense punctures, concealed behind antennze and somewhat obscured in front. Scape inserted one-third from apex of rostrum, almost the length of funicle. Prothorax moderately transverse; with dense, round, concealed punctures. LZlytra oblong-cordate, about one-fourth wider than prothorax, base moderately trisinuate; with rows of large almost-concealed punctures; third and fifth imterstices slightly raised. Mesosternal receptacle moderately long, with a _ distinct median keel. Femora distinctly grooved. Length, 53-7 mm. 287 Q. Differs in having the rostrum somewhat longer, sides more distinctly incurved to middle, punctures much smaller and concealed only at basal third, scape inserted not quite as close to apex of rostrum, and abdomen more convex. Hab.—New South Wales: Galston (D. Dumbrell) ; Queensland: Mount Tambourine (A. M. Lea). Type, I. 1530. Differs from the generic description in having the scape almost as long as the funicle, and inserted distinctly nearer apex than base of rostrum; but, as the other features agree, it does not appear desirable to refer it to a new genus. The scales on the prothorax and under-surface are large, and individually distinct. On the prothorax the sooty ones are in the majority. On the elytra they clothe most of the surface, the paler ones form a distinct but not sharply-defined fascia before the middle, commencing narrowly at the suture, and gradually, and then rapidly dilated, till it covers more than half of each side, but towards the sides it is sometimes broken up; on the apical portion of the elytra also the paler scales are rather numerous. On the under-surface and legs there are but few sooty scales. On the elytra there are numerous stout sub- erect scales, more numerous on the odd than on the even inter- stices, but they do not form distinct fascicles. The third and fifth interstices have their derm but little elevated, but owing to their clothing they appear to be rather distinctly elevated. Looking up the elytra from behind the stout scales appear almost like rows of opaque granules. METYRCULUS MEDIOMACULATUS, N. Sp. 3. Black, in parts diluted with red; antennez and tarsi red. Densely clothed with scales, larger and more clearly defined, individually, on abdomen than elsewhere ; each elytron with a distinct pale spot just before the middle. Upper-surface with numerous stout and more or less erect scales scattered about. Head with dense concealed punctures. Rostrum of mod- erate length, almost parallel-sided; apical half with crowded and fairly large punctures, basal half with larger but con- cealed ones. Scape distinctly shorter than funicle, inserted about two-fifths from apex of rostrum. Prothorax moderately transverse ; with dense partially-concealed punctures. EHlytra not much wider than prothorax, base evenly trisinuate, sides parallel to near apex; with rows of large partially-concealed punctures; third and fourth interstices lightly elevated, but the third conspicuously so near base. Mesosternal receptacle rather short and not keeled. Femora rather lightly grooved. Length, 44-6 mm. 288 Q. Differs in having the rostrum somewhat longer and thinner, with much smaller (but still distinct) punctures, con- cealed only about base; scape inserted in middle of rostrum, and abdomen more convex. Hab.—Queensland; Cooktown (Blackburn’s collection) ; Endeavour and Bloomfield Rivers (C. French); Kuranda (H. Hacker); Cairns (E. Allen). Type, I. 1531. With two elytral spots as in b:maculatus, but third inter- stice conspicuously elevated near base. On the upper-surface the scales are mostly of a slaty or sooty-brown, but on one specimen they are mostly of a light-brown. Some of the erect scales are ochreous, but they are usually sooty; on the elytra they are more numerous on the third and fifth interstices than elsewhere. The distinct spot on each elytron is of irregular shape, and on the third and fourth interstices; the scales composing it are usually whitish, margined with ochreous. On the under-surface and legs the scales are usually of a dingy- grey, but sometimes of a slaty-grey. METYRCULUS CINERASCENS, N. Sp. Q. Dark reddish-brown; rostrum black, except at apex. Densely clothed with greyish scales. Head with punctures entirely concealed. Rostrum moderately long, sides distinctly incurved to middle; with numerous small punctures, rather sparse about middle, but becoming denser and larger towards base. Scape inserted almost in exact middle of rostrum, distinctly shorter than funicle. Prothoraz moderately transverse, rather convex; with dense concealed punctures. Hlytra not much wider than prothorax, base rather lightly trisinuate, sides almost parallel to beyond the middle; with rows of large partially-concealed punctures; third interstice with an obtuse swelling near base. Mesosternal receptacle with thin U-shaped walls; almost open. /emora indistinctly grooved. Length, 4 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, T. 1532. The mesosternal receptacle is longer and more typically U-shaped than in bimaculatus, but as, when viewed from in front, its upper margin is seen to slightly overhang the base, it could not strictly be regarded as open. In build and general appearance it is something like Tychreus reversus, but that species has conspicuously dentate femora. The rostrum is of a shining-black, except at the tip; but the general surface, where visible, is of a rather dingy reddish-brown ; the claw joints and tibial hooks are paler, but the antenne are almost black, although diluted with red in parts. The scales are all more or less greyish, but towards the base of the 289 elytra they have a slightly sooty appearance, and towards the apex they are whitish. There are a few stout suberect scales scattered about. The type is without clothing on the rostrum, but probably the male is clothed on at least the basal half. METYRCULUS SINUATUS, N. sp. ¢. Ofa dingy brownish-red, some parts paler. Densely clothed with scales mostly of a light slaty-brown or grey, variegated with paler and darker ones; with numerous stout suberect scales scattered about, and in places condensed into fascicles. Head with dense concealed punctures. Rostrum rather wide and short, sides diminishing in width to middle; with dense punctures concealed on basal half. Scape inserted in middle of rostrum, distinctly shorter than funicle. Pro- thorax moderately transverse, subconical; punctures quite concealed by clothing. WZlytra rather short and convex, about one-third wider than prothorax, base feebly sinuous, sides parallel to beyond the middle; with rows of large almost- concealed punctures, but striation distinctly traceable; with feeble swellings beyond the middle supporting fascicles, but third interstice with a conspicuous one near base. Meso- sternal receptacle with basal portion rather short, and not distinctly keeled. Femora feebly grooved and very indis- tinctly dentate. Length, 23-3 mm. @. Differs in having rostrum slightly longer, with smaller punctures, concealed only on basal third; scape in- serted slightly nearer base than apex of rostrum and abdomen more convex. Hab.—New South Wales: National Park (Taylor Bros. and A. M. Lea); Jenolan (J. C. Wiburd and A. M. Lea). ype, £1533. The femoral teeth are extremely minute, and are so con- cealed by scales that it is only from certain directions that they can be seen at all. In fact from some specimens they appear to be absent. The scales are mostly of a rather light brownish-grey, verging to almost white on parts of the legs and under-surface; on the elytra there is sometimes a sooty © spot on each side about the middle; across the summit of the posterior declivity there is a more or less distinct fascia of pale scales, on one specimen almost of a snowy whiteness, but usually rather dingy. On the prothorax the suberect scales are more numerous on the apical than on the basal half, but they do not form distinct fascicles. On each elytron there are four fascicles, a distinct one crowning the tubercle on third interstice near base, and three smaller (sometimes very feeble) ones, close together about the middle: one on the second K 290 interstice, one level with it on the fifth, and the other on the third, slightly beyond the others; the latter one is sometimes entirely composed of whitish scales, and sometimes of sooty and whitish ones, and the strie at its sides are deflected out of straight lines by the slight swelling on which it is supported. A specimen from Wollongong differs in being very small (24 mm.) and with the elytral scales mostly sooty, but with the pale fascia distinct. Another, of the same size, from Cairns, has the scales on the upper-surface of an uniform pale slaty-grey, with a sooty spot on each side. On all the speci- mens, however, the postmedian sinuation of the second and third striz is distinct. MENIOMORPHA INCONSTANS, Lea. Some specimens, from the Northern Territory, have whitish scales occupying most of the upper-surface. On one specimen the dark scales occupy a subquadrate medio-basal patch on the prothorax, a patch on each elytron at the base between scutellum and shoulder, and an irregular postmedian band, the band irregularly dilated on suture both in front and behind. Queensland specimens usually have the white’ occupying much less of the surface—usually a strongly curved mark on each side of elytra at the base, the two meeting at the scutellum, and an irregular patch on each side of apex. On the prothorax the only white markings are remnants (at base and apex) of a median line. TYCHREUS. In the diagnosis of this genus,(25) based largely on the typical species (camelus), the eyes were described as finely faceted, the rostrum thin, and the mesosternal receptacle almost open; and these characters apply to most species of the genus. But some of the smaller ones have the eyes moderately or rather coarsely faceted, and with the rostrum of the males rather wide. In three species also (sellatus, imcanus, and nigronotatus) the receptacle, although its emargination is U-shaped, has the base considerably wider than the sides, although not to such an extent as is usual in Pseuwdometyrus and J etyrus. (24) TYCHREUS REVERSUS, Lea. The facets of the eyes of this species, although hardly coarse, are still larger than in most species of the genus. A small (3 mm.) male from Cairns has a conspicuous dark fascia (23) Proc. Linn. Soc., N.S.W., 1909, p. 617. (24) This to a certain extent is sexual; asin 7. sellatus, the base is wider in the male than female. 291 at the basal third of its elytra, but at the sides the fascia is directed forwards, and almost extends to the base. Two other males have but feeble remnants of the dark, subquadrate, pro- thoracic patch. TYCHREUS SELLATUS, Pasc. On the typical form of this species the clothing is mostly of a dingy-whitish colour, with a large ovate dark spot, common to prothorax and elytra. Var. A. On Mount Tambourine a form occurs whose scales are mostly pale ochreous-brown, and without a distinct ovate patch on the upper-surface, but generally there is a small dark spot of scales on the second interstice at the basal.third. TYCHREUS LANIFER, 0. sp. 3. Blackish, in places obscurely diluted with red, scape and funicle of a rather dingy-red. Densely clothed with soft, white, woolly-looking scales, in places compacted into depressed fascicles; a transverse patch near base of elytra, another at summit of posterior declivity, and some feeble spots on sides of a sooty-brown ; femora, and sometimes the tibiz, with obscure rings of sooty-brown. Under-surface moderately densely clothed. Hyes large and finely faceted. Rostrum moderately stout, sides lightly incurved to middle; with coarse punctures, con- cealed except on apical third. Scape as long as funicle. 1n- serted one-third from apex of rostrum. /Prothorax lightly transverse, sides strongly rounded, base strongly bisinuate, disc uneven; with dense, normally-concealed punctures. Hlytra wider than prothorax, base strongly trisinuate, parallel-sided to beyond the middle; with series of large, more or less con- cealed, punctures; interstices with numerous feeble swellings, supporting feeble fascicles. Wesosternal receptacle U-shaped, but base fairly large. Femora stout, strongly dentate. Length, 543-6 mm. Q. Differs in having the rostrum thinner, sides less noticeably incurved, and clothed only on basal fourth. Scape inserted slightly more distant from apex of rostrum, and base of mesosternal receptacle decidedly smaller. Hab. — North Queensland (Blackburn’s collection) ; Cairns (A. M. Lea). Type, I. 1452. In build close to sellatus, and I was at first inclined to regard it as a variety of that species, but besides the different clothing it has the rostrum decidedly shorter and wider in both sexes. At first glance it appears to be an elongated form of Chimades lanosus, with much shorter clothing than usual. The prothorax has four fascicles, supported by feeble tubercular swellings across middle, two behind same, and one in middle of base. K2 292 TYCHREUS LONGICORNIS, n. sp. Blackish ; antennz of a rather pale-red, but club darker. Densely clothed with rather large, soft, fawn-coloured scales, closely applied to derm; interspersed with short, stout, semi- erect, paler scales ; but on prothorax the interspersed scales are darker, or at. least no paler than the others. Prothorax with two distinct fascicles in middle, and a smaller one near each side; elytra with an elongated fascicle on third interstice and some feeble ones elsewhere. Eyes rather large, facets of medium size. Rostrum rather long, moderately curved, sides decreasing in width from base to antenne, thence parailel-sided to apex; basal third with sculpture concealed, elsewhere shining and with minute punc- tures. Antenne thin; scape inserted in middle of rostrum, the length of funicle; club elongate-elliptic. Prothoraz strongly transverse, sides strongly rounded and somewhat flattened, except in front, apex less than half the width of base; punctures normally concealed. Hlytra rather short, not much wider than prothorax; with rows of large partially- concealed punctures; with many small, irregularly-disposed swellings and an interrupted ridge on third interstice from near base to near middle. Mesosternal receptacle U-shaped, walls thin and lightly elevated. Front femora strongly dentate, the others moderately so; middle tibize somewhat angular near outer base. Length, 6 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, IT. 1453. Nearer to camelus than to any other described species, but the large elytral fascicles not quite in the same position, the mesosternal receptacle somewhat different, elytra almost conjointly rounded at apex, and facets of eyes larger. The antenne and rostrum are longer than usual. On the elytra there is a curved row of feeble tubercles on the posterior declivity, an oblique row from the fascicle on third interstice to each shoulder, and a few elsewhere. The type is probably a female. TYCHREUS DISCICOLLIS, n. sp. Blackish, in parts diluted with red; antenne and tarsi paler. Densely clothed with scales, mostly fawn-coloured and with more or less conspicuous fascicles. Eyes rather prominent, with facets of medium size. Rostrum moderately long, feebly curved, sides decreasing in width to antenne, thence parallel-sided to apex; basal two- fifths with dense concealed punctures, elsewhere shining and with small but distinct ones. Scape inserted slightly nearer apex than base of rostrum, slightly longer than funicle; funicle with first joint stouter and distinctly longer than 293 ‘second; club elliptic, almost as long as funicle. Prothoraz strongly transverse, base almost truncate, sides somewhat flat- tened and strongly rounded, apex scarcely half the width of base; punctures normally concealed. Elytra rather short, distinctly but not much wider than prothorax; with rows of large partially-concealed punctures; subtuberculate beneath fascicles. J/esosternal receptacle briefly U-shaped, very feebly elevated. /emora moderately dentate. Length, 33 mm. Hab.—Queensland: Mount Tambourine (A. M. Lea). ‘Type, I. 1454. A pretty little species, at first glance appearing close to dilaticollis, but fascicles near suture different, the subbasal one being much larger and longer, the submedian one larger and the third one (of dilaticollis) absent; there are other differences also. Along the middle of the prothorax the cloth- ing is much darker than on the sides; on it there are six fascicles: two distinct ones in middle, two loose ones at apex, and a loose one on each side. On the elytra there is a narrow transverse dark line about one-fourth from apex, and some feeble spots on the sides. The second interstice has a dis- tinct fascicle at summit of posterior declivity, and the third has an elongated and very conspicuous one towards the base; there are also some stout erect scales scattered about, notably at the apex. On the under-surface the clothing is almost uniformly stramineous. TYCHREUS INCANUS, N. sp. d. Of a dingy reddish-brown; antenne and tarsi paler. Densely clothed with soft muddy-grey scales, in places feebly variegated, and with some stout scales interspersed; with some moderately distinct fascicles. Under-surface with cloth- ing almost white. Byes rather prominent, with rather coarse facets. Rostrum moderately wide, sides distinctly incurved to middle; basal two-fifths with punctures concealed; elsewhere shining and with fairly large clearly-defined punctures. Scape in- serted about two-fifths from apex of rostrum, the length of funicle. Prothoraz strongly transverse, sides strongly rounded, base almost truncate and fully twice the width of apex; punctures dense but normally concealed. Llytra short, searcely wider than prothorax, parallel-sided to beyond the middle, base not trisinuate; with rows of large, rough, almost- concealed punctures; surface uneven in places, and sub- tuberculate beneath fascicles. IMfesosternal receptacle widely U-shaped, walls thin and strongly elevated. Femora moderately dentate. Length, 34 mm. @. Differs in having the rostrum thinner, with smaller 294 and sparser punctures, but concealed only close to base, and scape inserted nearer the middle of rostrum. Hab.—Queensland: Cairns district (A. M. Lea). Type, I; 1455. The coarse facets to the eyes would exclude this species from Tychreus, and place it in Acrotychreus, according to the table given in Proc. Linn. Soc., N.S.W.,(5) but its legs are very different to those of that genus. Its mesosternal receptacle also has the base wider than in most species of Tychreus. In build it is much like fumosus, but with coarsely- faceted eyes, rostrum shorter, the scales differently coloured, and fascicles differently disposed. On the male the clothing of the upper-surface is scarcely variegated, but on the female there is a distinct and fairly large medio-basal dark patch on the prothorax, and a strongly curved line on each elytron, commencing at the fascia on the third interstice, and touching the side at the basal third. On the prothorax there are two feeble median fascicles, and remnants of others at the sides and apex. On the elytra there are rather numerous very feeble fascicles, but a distinct and moderately long one on the third interstice near base. TYCHREUS LATIFRONS, Nn. sp. Of a dingy reddish-brown. Densely clothed with soft scales, mostly fawn-coloured, or somewhat ochreous; with stout scales scattered about, and in places condensed into fascicles. Hyes rather coarsely faceted. Rostrum rather stout, sides distinctly incurved to middle, apex as wide as base; extreme base with concealed sculpture, elsewhere shining and with rather small clearly-defined punctures. Scape inserted in middle of rostrum, distinctly shorter than funicle; club rather briefly ovate. Prothorax moderately transverse, sides moderately rounded, base bisinuate and not twice the width of apex; punctures normally concealed. Hlyétra rather short, basal half parallel-sided; with rows of large partially- concealed punctures; subtuberculate beneath fascicles. Meso- sternal receptacle rather strongly elevated at base, and rapidly sloping to apices; walls thin and widely U-shaped. Front femora lightly, middle moderately, hind strongly dentate. Length, 3 mm. ‘ Hab.—Queensland: Cairns district (A. M. Lea). Type, [. 1456. The facets of the eyes are rather coarser than in most, species of the genus, although not as coarse as in incanus. In general appearance it is something like a small specimen (25) For 1909, pp. 594-595. 295 “of reversus, but with feeble fascicles at summit of posterior declivity, rostrum distinctly shorter and wider, and inflated at apex; fwmosus is- wider, with different clothing and rostrum. In many species of the genus the rostrum is slightly ‘dilated from the antenne to the apex, but the apex is not as wide as the base; but in this species it is quite as wide. On each elytron the sides are rather largely variegated with black scales, and the same are continued in two feeble zones to the suture, and with the fascicles in same (one on the third inter- sstice mear base, one on the second near middle, and two smaller ones on the third) also black. On the third, at summit of posterior declivity, there is a fascicle of whitish scales. On the prothorax there is a subquadrate, medio-basal patch of dark scales. EKURYMETOPOCIS, n. g. Head rather flat, entirely concealed from above. Eyes widely separated, coarsely faceted. Rostrum feebly curved, base wide, but decreasing in width to beyond the middle. Scape inserted somewhat nearer apex than base, shorter than funicle; two basal joints of funicle elongate; club elongate- ovate. Prothorax oblong. Scutellum minute. Llytra dis- tinctly wider than prothorax at base. Pectoral canal deep and wide, terminated just beyond front coxze. Mesosternal receptacle somewhat raised, emargination widely transverse; cavernous. Metasternum elongate, not much shorter than the following segment. Abdomen rather long, sutures straight, intercoxal process narrow, first segment almost as long as the three following combined, second the length of fifth, and slightly longer than third and fourth combined. Legs moderately long; femora shallowly grooved. The dilated front of the prothorax of the typical species is somewhat suggestive of Hxithius cariosus, but is essentially different, as in that species the extreme apex is very narrow, whereas in this species the whole apex is produced and bilobed. But the long metasternum indicates that the genus is widely separated from Haithwus and it really belongs to the Chetectetorus group, and provisionally may be placed near T'ychreus. The whole of the derm, except of the apex of the rostrum, is densely clothed with large soft scales, giving it a somewhat laminated appearance, and quite concealing the metasternal episterna. No femoral teeth are visible, but about the middle of each femur a feeble swelling may be noticed, probably denoting that a minute tooth is there covered up by scales. When the head is viewed directly from above only the upper edges of the eyes are visible. Wings are probably present, but I have not made certain of same. 296 KURYMETOPOCIS BILOBUS, N. sp. Densely clothed with somewhat variegated scales, mixed with stouter ones, condensed in places into fascicles. Head evidently with dense but entirely-concealed punc- tures; with a distinct inter-ocular fovea. Rostrum on apical half with small but clearly-defined punctures, elsewhere con- cealed. Prothoraz slightly longer than wide, basal two-thirds parallel-sided, apex somewhat dilated and distinctly bilobed, derm concealed. Hlytra about twice the length of prothorax, and base about one-fourth wider, sides somewhat uneven ; with rows of large punctures, traceable through clothing; with a very conspicuous tubercle crowned with stout scales on third interstice near base; third, fifth, and seventh with small fas- cicles or tubercles on basal half. Length, 6} mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, I. 1476. The tarsi, antenne, apical half of rostrum, and under- parts of head more or less reddish, but the rest of the insect is so densely clothed that the derm is concealed, and the type being unique and in beautiful condition it has not been partially abraded. It was beaten from a newly-felled tree at Malanda. On the prothorax most of the scales are of a dingy- brown, the sides and apex are fringed with stouter ones, and there are two fascicles on the disc. On the basal half of the elytra (except for a large scutellar fawn-coloured patch) the scales are similarly coloured, but on the apical half they are whitish-grey; on the under-surface, legs, head, and base of rostrum the scales are mostly of a greyish-brown, mixed with stouter and darker ones. From the sides the apex of the pro- thorax appears as a wide flat ridge, overhanging the head. THEREBIOSOMA VARIEGATUM, Nn. sp. 3. Black; antenne of.a dingy-red. Densely clothed with stout variegated scales. Head with dense normally-concealed punctures. Rostrum moderately stout, slightly decreasing in width from base to antenne, thence parallel-sided to apex; basal two-fifths with coarse partially-concealed punctures, elsewhere with smaller but cleary-defined ones, an impunctate line along middle between antennez. Antenne rather stout; scape inserted slightly nearer apex than base of rostrum, about half the length of funicle and club combined; first joint of funicle about as long as second and third combined, second about as long as third and fourth combined. Prothorax moderately transverse, sides strongly rounded, base strongly bisinuate and more than twice the width of apex; with dense normally- concealed punctures and with a feeble median carina. EKlytra 297 very little wider than prothorax, parallel-sided to apical third, base strongly trisinuate ; with rows of large partially-concealed punctures; interstices with dense normally-concealed ones. Under-surface with rather dense punctures. Basal segment of abdomen obliquely flattened in middle. Legs stout; femora rather lightly dentate; each tibia with a strong apical hook and a moderately strong subapical tooth. Length, 6-85 mm. Q. Differs in having the rostrum somewhat longer and thinner, antennz inserted slightly nearer base than apex of rostrum, and basal segment of abdomen convex in middle. Hab.—Queensland: Cairns district (A. M. Lea); Kur- anda (G. E. Bryant). Type, I. 1465. Differs from rhinarioides in being larger, very differently clothed, mesosternal receptacle longer, and femora dentate. In general appearance it is remarkably close to Veozeneudes dives, but the mesosternal receptacle is U-shaped, strongly concave, although not cavernous, with very thin walls, middle tibiz not bidentate externally, etc. The second joint of funicle is also very different. The femoral teeth are rather small and parti- ally concealed by clothing. The majority of the scales are of a more or less ochreous colour, but on some specimens hardly more than stramineous. On the prothorax there is always a small sooty spot on each side of the base, and often four feeble ones across middle and two at apex. On the elytra the sooty scales are in large irregular patches or zones, and occupy from one-third to a little more than half of the surface; they are usually absent, or almost so, from the posterior declivity, and most numerous about the middle and near the base. On some specimens the pale scales adjoining the larger dark elytral patches are almost white. On the legs the clothing is almost entirely ochreous. On the metasternum it is largely sooty, and on the abdomen almost entirely so. On the upper-surface the scales are not closely applied to the derm, but project from same at a slight angle. The sexual differences are but slightly pronounced, as the clothing and punctures of the rostrum are practically identical in both sexes. The female is usually, but not always, somewhat larger than the male. There are three specimens of the species in the British Museum labelled as from Albany (in Western Australia), but the locality is certainly wrong. Var. A. Three specimens from Marmor (Queensland: H. W. Brown) differ from the type in having sooty scales absent from the under-surface, almost absent from the prothorax, and on each elytron confined to a large submedian spot, and to a smaller subbasal one; but the latter on some specimens is very feeble. The scales on the upper-surface also are distinctly shorter and more closely applied to the derm. 298 CAaTOCALEPHE, Blackb. (26). The late Rev. T. Blackburn referred this genus to the Aterpides with considerable hesitation, and certainly it seems: out of place there. In many respects the only known species appears as if it should be referred to the Psepholax group of the Cryptorhynchides, and to the vicinity of Therebus and. Pseudotherebus. Its front coxe, however, are almost touch- ing, and this would appear to exclude it from the subfamily altogether. But there is a distinct channel in front of the- front cox, although it is not acutely margined, neither is the: channel acutely margined in Psepholax or in Hybomorphus; the intercoxal process of its mesosternum is also unsually small. for any member of the Psepholax group. The sides of the rostrum, the antenne, and the legs are somewhat as in. Zeneudes. In Zeneudes and Oreda each wal! of the pectoral canal is supplied at its apex with a tooth-like projection, much as in C’. minans, but it is placed at a slight distance from the- ocular lobe itself. On the whole, I think it should be regarded as an aberrant genus of the Cryptorhynchides, and in cata-- logues should be placed near Therebus. CATOCALEPHE MINANS, Blackb. The types of this species are in the South Australian. Museum. The male has the rostrum curiously dilated to its: apex, and the lower edge of the apex (just behind the man- dibles) is supplied with an obtuse tubercle on each side; these- are very distinct when the rostrum is viewed from the sides. From some directions the mandibles, when clenched, cause: the apex of the rostrum to appear spade-shaped, much as in many species of Cossonus. In the female the rostrum is less. dilated to its apex, and there are no tubercles on the lower side; the teeth at the apex of the pectoral canal are also smaller. | AMPAGIA HYSTRICOSA, N. sp. Dark reddish-brown; antennz and tarsi paler. Rather densely clothed with dingy greyish-brown scales, but variegated on elytra; with numerous stiff erect scales scat-- tered about. Head with concealed punctures. Rostrum wide, sides: distinctly incurved to middle; with dense punctures, dis-- tinct at apex but elsewhere concealed. Antenne stout, in- serted in middle of rostrum; scape scarcely half the length: of funicle and club combined. Prothorax subconical; punc-- tures concealed.

Soc., S.A., 1895, p. 220. 299 in light but traceable striz. Basal segment of abdomen with dense punctures; and with a large subtriangular space marked off by a ridge on each side, the two ridges meeting at the middle of the apex. /emora stout, strongly grooved, hind pair wide and angularly dilated. Length, 14-13 mm. Hab.—Queensland: Bundaberg (A. M. Lea). Type, I. 1888. A minute, strongly convex, elliptic species; readily dis- tinguished from all others of the genus by the stiff erect scales thickly scattered about on the upper-surface, rostrum, and legs. Pascoe, it is true, described erznacea as having ‘‘squamis nigris opacis validis erectis’’; but six specimens of that species before me from King George Sound (the type locality) are not so clothed, the larger scales being all more or less de- cumbent, certainly nowhere projecting at right angles to the derm. On the elytra there is a feeble spot of dark scales in the scutellar region, and a more distinct one, or fascicle, on the suture about the middle; from the latter a vague, dusky, oblique stripe extends forward halfway towards each side, and there are some whitish scales accentuating the dark ones. The three typical specimens are apparently all males. ALATIDOTASIA RUBRIVENTRIS, Lea. Three specimens, recently taken at Cairns, probably belong to this species, but they differ from the types in having the under-surface as dark as the upper. The rostrum is shorter, and antenne stouter, but these may be sexual characters; if so, these are males, and the types are females. ALATIDOTASIA ELLIPTIOCA, 0. sp. Black, shining; antenne and claws somewhat reddish. Under-surface and legs with a few white scales, a narrow stripe of white scales on each side near apex of elytra. Head with distinct punctures in front; a distinct impres- sion between eyes. Rostrum rather short, sides distinctly incurved to middle, widest near base, but base itself notched on each side; about base with distinct punctures, elsewhere almost or quite impunctate. Scape stout, inserted slightly nearer apex than base of rostrum, about half the length of funicle and club combined. Prothoraz ‘strongly transverse ; with not very dense and small punctures, becoming somewhat larger on sides. Elytra elongate-cordate, closely applied to and outlines continuous with those of prothorax; with very narrow striz, containing minute and distant punctures, but a few fairly large ones at base and sides; interstices not separately convex. Abdomen with first segment depressed 300 near base, almost as long as three following combined, witl: a few distinct punctures; third and fourth each with a dis- tinct row across middle; fifth with dense ones. Legs long and rather thin; femora distinctly grooved and lightly dentate ; claws minute. Length, 24 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, T. 1542. In general appearance extremely close to rubriventris, but rostrum stouter, head impressed between eyes, and all the elytral strie distinct. The emargination of the mesosternal receptacle is also more transverse, and the punctures at sides of prothorax are more distinct. In some lights an extremely fine row of punctures can be traced on each elytral interstice, but from most directions they are quite invisible. ALATIDOTASIA MACROPS, N. sp. Shining dark reddish-castaneous, some parts darker; antenne paler. Under-surface and legs with sparse white scales; a small spot of white scales on each side of elytra near apex. Head with moderately dense punctures. Hyes large and almost touching in middle. Rostrum moderately stout, sides distinctly incurved to middle, widest near, but notched on each side of base; with rows of rather large punctures, becom-- ing smaller in front. Scape stout, inserted nearer base than apex of rostrum, not half the length of funicle and club com- bined. Prothorax moderately transverse; with fairly large but not very dense punctures. LHlytra elongate-cordate, some- what wider than, but outlines subcontinuous with those of prothorax; with rows of not very large punctures, in deep striz; interstices wider than striz, each with a row of very small punctures. Abdomen with first segment scarcely longer than second, second almost as long as third and fourth com- bined; first and second with dense and coarse punctures, fifth with smaller ones, third and fourth each with one row across middle. /Femora rather stout, widely grooved, edentate, front pair dilated towards, but suddenly narrowed near base; tibiz narrow, angular at base; claw joint very thin, claws minute. Length, 3 mm. Hab.—Queensland: Cairns district (A. M. Lea). Type, T. 1543. A somewhat aberrant species, as the femora are edentate, and the large eyes, almost meeting in front, give a very different appearance to the head from that of rwbriventris or the preceding species. In general appearance it is like some of the small shining species of Welanterius. The elytral strize are narrower than the interstices, and are very sharply defined. 301 DESCRIPTIONS OF AUSTRALIAN CURCULIONIDA, WITH NOTES ON PREVIOUSLY DESCRIBED SPECIES. Part XI. By ArtHur M. Lea, F.E.S. [Read September 11, 1913.] I am greatly indebted to Mr. Gilbert J. Arrow, of the British Museum, for the opportunity of examining some co- types of Mr. Pascoe’s Curculionide, these enabling me to identify with certainty several genera and species which could not be identified from the descriptions alone, some of these being not alone insufficient but actually misleading. The species sent were : — Acacallis personuta. Acalles expletus. Byrsia cerata. Diethusa fervida. Emde cstuans. E. porphyrea. EF. sanvosa. Melanterwus fugitivus. Onidistus odiosus. Paleticus wmvidus. Poropterus python. Tentegia favosa. Some notes have also been prepared on other specimens which Mr. Arrow was kind enough to compare with their types. All the species here noted or described belong to the sub- family Cryptorhynchides. ACAGALLIS. Mr. Pascoe described the apex of the pectoral canal in this genus as open, but in the co-type of A. personata before me it is certainly cavernous, and this is a very important feature in the subfamily Cryptorhynchides. He also described the base of the prothorax as truncate, but it is distinctly, although rather lightly, trisinuate. The rostrum of the female (the sex of the co-type) is almost perfectly straight, but that of the male is lightly curved. I can find nothing warranting its generic separation from Orocihlesis. 302 ACACALLIS PERSONATA, Pasc. (now Orochlesis ). (Queenslandica munda, Lea.) Deceived by the above-noted discrepancies, I redescribed this species under the name of Queenslandica munda. Mr. Pascoe said “the pattern at the base (of the elytra?) has a resemblance to the face of some animal.” I cannot see any such resemblance, however, either on the co-type or on four other specimens. ACALLES EXPLETUS, Pasc. (now Decilaus.) (Decilaus squamipenns, Lea.) The co-type of this species sent for examination certainly belongs to Decilaus and to the species subsequently described by me as D. squamipennis. The type was possibly somewhat abraded, as Pascoe described the elytra as sulcate-punctate ; this is the case, but the punctures are normally so concealed by clothing that they appear to be very small, and many are quite concealed. Nor did Mr. Pascoe mention the dentition of the front femora. BYRSIA. The co-type of B. cerata sent bears a name-label in Mr. Pascoe’s own writing. The genus was referred to the Cryptor- hynchides with doubt, Mr. Pascoe thinking it possibly be- longed to the Hrirhinides; it might, in fact, very well be referred to that subfamily, but as.some of its characters denote an approach to Diethusa, it may, perhaps, be allowed to remain in the Cryptorhynchides. The pectoral canal is represented by a rather deep and squamose, but not acutely margined, groove in front of the front coxe; these are lightly but distinctly separated, but the canal between them is not sufficiently wide to allow the rostrum to pass below them. The mesosternum is longer than usual, with the middle coxz at its hind*margin, so that they are rather more distant from the front pair than is usual, and they are rather more widely separated than that pair. The mesosternum between them is not in the form of a special receptacle, but slopes up till it joins in with the metasternum. The suture between the two basal segments of abdomen is certainly not obsolete in the middle (as described), but pos- sibly on the type the clothing was matted together there. The eyes are coarsely faceted. ByRSIA CERATA, Pasc. The co-type is a male, its under-surface is densely clothed with silvery scales, the two basal segments of its abdomen are conjointly concave, with the depression traceable on to the metasternum. The basal third of the rostrum is squamose, 303 elsewhere shining and with distinct punctures, having a tendency to become confluent posteriorly. The locality given by Mr. Pascoe was simply Queensland ; but a male in my collection (from the Macleay Museum) is labelled as from Rockhampton. A female (also from Rock- hampton) in the British Museum differs from the male in being slightly stouter, rostrum thinner and clothed only at extreme base, and basal segments of abdomen gently convex. DIETHUSA. Two co-types of D. fervida were sent, and one bears a name-label in Mr. Pascoe’s writing. I cannot see that any of the tibie are bicalcarate at apex, the supposed inner spurs are simply tufts of hairs in the usual positions. Probably on the type these tufts were cemented together, and so appeared as mucros. There are certainly, however, several species of Diethusa and Melanterius, whose front tibie are bicalcarate at apex. Other characters relied upon to distinguish the genus from Lybeha and Enide were the subulation of the rostrum and abdominal sutures, but these are of specific importance only.“ Previously I united Hnide and Lybeba, and now propose that these be merged in Dethusa, that name having priority of pagination. (2) DIETHUSA FERVIDA, Pasc. (Lybepa acuticosta, Lea.) One of the co-types is labelled South Australia, the other Gawler. They are evidently sexes: in the male the antennz are inserted nearer the apex of the rostrum than in the female, and the rostrum itself is wider and less subulate in front of same, although distinctly narrowed to the apex. Mr. Pascoe described the general colour as black, and the rostrum as brownish-ferruginous or ferruginous; the co-types have the rostrum blackish, with the apical fifth in the male and the apical fourth in the female reddish. I have redescribed the male of the species under the name of Lybeba acuticosta, but the form described as the female of L. acuticosta was wrongly referred to that species, and really belongs to D. metasternalis. ENIDE @STUANS, Pasc. (now Diethusa). Four co-types sent, one bearing a name-label in Mr. Pascoe’s writing. They agree with the species I redescribed as such.

(3) Proc;tann, See:, N.S: W., 1899) p. 253. 304 ENIDE PORPHYREA, Pasc. (now Diethusa). Two co-types sent, one bearing a name label in Mr. Pascoe’s writing. They agree with the species I redescribed as such. (4) ENIDE SANIOSA, Pasc. (now Diethusa subfasciata, Pasc., var. ). A somewhat abraded specimen sent as a co-type of ZL. samosa. J cannot regard it as more than a slight variety of the common, widely distributed and variable swbfasciata. MELANTERIUS FUGITIVUS, Pasce. The co-type cf this species sent for examination is cer- tainly different to any species previously seen by me. It is a fairly large species, its upper-surface densely but not quite uniformly clothed with somewhat golden scales; the under- surface with paler and thinner scales, not quite as dense as on the upper-surface, but certainly not “‘sparse’’ (as described). The combined length of the third and fourth abdominal segments is just perceptibly more than that of the second, but distinctly more than that of the fifth. The femoral dentition is strong. The punctures of the meta- sternal episterna are moderately dense at base and apex, but in a single series along the middle. In my table of the genus ©) it would be associated with wnisertatus, which is a much smaller species, with very different clothing, etc. ONIDISTUS opIOSUS, Pasc. The specimen sent as a co-type of this species bears a label ‘“K. G. 8.,’’ on which are some marks that probably were intended for(?). It is simply a small specimen of araneus, and the locality—King George Sound—is certainly incorrect. O. araneus is a common species in the coastal scrubs of Northern New South Wales and of Southern Queensland. PALETICUS INVIDUS, Pasc. (now Luryporopterus). (Euryporopterus angularis, Lea.) A co-type of P. invidus was sent with another specimen, both labelled as from Queensland and as from Pascoe’s col- lection. The description is somewhat misleading, as the third, fifth, and seventh interstices of elytra are described as elevated, especially posteriorly; whereas the elytra are with- out interstices in the accepted sense, the elevations mentioned being really due to fascicles or clusters of scales; the position COMENG s,s 202. (5) D. c., p. 206. 305 of the seventh interstice is occupied by a strong epipleural fold. The species belongs to Luryporopterus, and was subse- quently described by me as #. angularis. POROPTERUS PYTHON, Pasc. (P. listroderes, Lea). The co-type of P. python sent belongs to the species I subsequently described as P. listroderes. Mr. Pascoe’s description is rather faulty, and before seeing the co-type I was under the impression that the species was not really a Poropterus. TENTEGIA FAVOSA, Pasc. A specimen sent as a co-type of this species, from Mr. Pascoe’s collection, is labelled Australia; the type was stated to be from Western Australia. But as the specimen now before me has the front and hind femora moderately, and the middle pair rather strongly dentate, and in the original description the femora are noted as edentate, it is probable that the specimen really belongs to a species closely resembling, but not, favosa, although associated with the type by Mr. Pascoe. ‘“) There are two species in my collection resembling the supposi- titious co-type; anolpa with prothoracic punctures identical and elytral granules very similar, but with shoulders clasping the prothorax and femora edentate; and quadri- seriata also with similar punctures on the prothorax, but that segment carinated. PERISSOPS ILIAcUS, Pasc. (now Critomerus). (Critomcrus emblematicus, Lea.) Mr. Pascoe said the type of Perissops was the Enteles ocellatus of Redtenbacher; and in naming the genus he referred two additional species to it—mucidus (a common weevil in the coastal forests of Northern New South Wales and of Southern Queensland) and dliacus (from Gilolo, Aru, etc.). As a generic feature he described the front femora as “obsolete dentata, vel dente parvo instructa.” Whilst of «iacus he wrote “femoribus, presertim anticis, dente acuto instructis.”’ Dr. Gestro sent me four Yule Island specimens as P. thaca, ©) but their front femora are bidentate; as they were not from any of the type localities, and belong to the species I named Critomerus emblematicus, I sent two of them to Mr. (5a) Since this was written Mr. Arrow las informed me that the specimen sent is really not favosa, although extremely close to it in general appearance. (6)In Ann. Mus. Civ. Gen., 1885, p. 269, the species was recorded as from Yule Island, and given a feminine termination. 306 Arrow for his opinion, pointing out that their front femora. were quite conspicuously bidentate.) In reply he wrote: “T have carefully compared your specimens with Pascoe’s type of Perissops thacus, and am satisfied that they belong to that species. Pascoe’s collection contains five specimens, varying a good deal in pattern, and the one he has marked ‘type’ (from Gilolo) has the prothorax almost entirely white, but I think there is no doubt all are the same.” Although the species: emblematicus must now be regarded as synonymous with aliacus, the generic name Critomerus must be retained, as the conspicuously bidentate femora are strongly at variance with: all the (now numerous) known species of Perissops. MECHISTOCERUS. Berosiris. Dr. Gestro sent me three specimens as co-types of B.. calidris, but as they were from Yule Island, and that locality was not mentioned under the original description I thought it desirable to have them compared with the type, and sent them to Mr. Arrow with a note as follows: “I would specially draw your attention to the walls of the pectoral canal, almost attached to the hind margin of the front coxe you vill notice ridges margining the canal (a feature that denotes the species: is a Mechistocerus). These ridges are, however, easily over- looked, if the specimen is pinned in the ordinary way. If B. calidris (type) has these processes, possibly others of that genus have, in which case possibly the name should be treated as synonymous with M/echistocerus. The genus Berosiris was- originally described in the Journal of the Linnean Society, ® and five species were then named. As _ icticollis was: figured (9) and the first named, apparently it should be regarded as the type; and I would therefore be glad to know if its. pectoral canal is as in the specimens sent, especially as to the processes just behind the front coxe.’’ In reply Mr. Arrow wrote: “TI have examined the type of Berosiris calidris, and although your specimens cannot be regarded as co-types, I think they are probably the same. Pascoe had specimens from Yule Island, but left them unnamed and separated widely from B. calidris. The form of the pectoral canal is exactly the same in all species of Berosiris- (including B. picticollis) as in your specimens, and Mr. Mar- shall tells me that Berosiris and Mechistocerus have long been: (7) The second tooth is midway between the first and the base of” the femur; in several species of the genus there is a small supple-- mentary tooth in the femoral emargination. (8) Zool., xii., 1873, p. 43. COLE! ies Tear 307 regarded as synonymous, and he believes were announced to be ‘so by Faust.) From two specimens of J/. compositus (Lea) received from you, I think it most likely that that is a synonym of B. calidris.” BEROSIRIS CALIDRIS, Pasc. (now Mechistocerus). Mechistocerus compositus, Lea. M. compositus, Faust (?). This is a very variable species, and is common in many parts of Northern Queensland and New Guinea. I redescribed it under the name of composttus in 1907.00 Subse- quently “2) the late Herr J. Faust also named a species com- positus, and quite probably his species is the same as calidris; the description is but little more than a comparison with M. nigrostriatus. DystRopicus. (13) (Berosiris, Lea, in error. )(4) I received from Dr. Gestro seven specimens as co-types of Dystropicus squalidus, and as coming from the type locality (Yule Island). They agree fairly well with the generic and ‘specific descriptions, but differ in the rostrum being decidedly long, certainly not ‘‘modice elongatum’’ and the second joint of the funicle at most twice the length of the first, certainly not ‘‘triplo.”’ These discrepancies, however, are but on a par with others in Pascoe’s descriptions, and I believe the specimens to be correctly named. Deceived by these and other inaccuracies I redescribed the genus as the Berosiris of Pascoe. Dystropicus was re- ferred to another section (Sophrorhimine) of the subfamily, to the one (Cryptorhynchine) in which he placed Berosiris. DYSTROPICUS SQUALIDUS, Pasc. (15) Berosiris miztus, Lea. The types of B. mixtus agree with the co-types above noted of D. squalidus. BEROSIRIS TANYRHYNCHUS, Lea (now Dystropicus). This species must. now be transferred to Dystropicus. (10) Stett. Ent. Zeit., liii., p. 46. I have not seen the reference, ‘however. (11) Proc. Linn. Soc., N.S.W., p. 409. (12) Stett. Ent. Zeit., 1898, p. 143. (13) Pascoe, Ann. Mus. Civ. Gen., 1885, p. 252. (14) Proc.

Densely clothed with stout sooty scales, variegated with whitish spots. Eyes very coarsely faceted and widely separated. Rostrum long, thin, and moderately curved, basal half with a median carina; basal third with coarse concealed punctures, elsewhere with smaller clearly-defined ones. Scape thin, somewhat shorter than funicle, inserted two-fifths from apex of rostrum; first joint of funicle slightly longer than second. Prothorary moderately transverse; with dense, normally almost-concealed punctures; with a feeble remnant of a median hne. #lytra rather long, decidedly wider than pro- thorax, parallel-sided to near apex; with rows of rather large but normally almost (or quite) concealed punctures, in dis- tinct striz; alternate interstices strongly elevated. Under- surface with dense and rather coarse punctures; but a single row in middle of each of the metasternal episterna. Basal segment of abdomen flattened in middle; apical with a trans- verse impression. Four hind femora each with a small but acute tooth, the others with a still more minute one. Length, 53-64 mm. Q. Differs in having the rostrum with smaller pune- == tures and antennz inserted not quite so close to apex. Hab.—Queensland: Dalby (Mrs. F. H. Hobler). The individual scales are wide, and give the surface a somewhat plated appearance; on the under-surface they vary from mostly white to mostly sooty. This and the two following species (and there are at least two other undescribed species of the same group) might have been referred to a new genus rather than to Melanterius; and two of them in fact have the tip of the rostrum not continued beyond the mesosternum, and this, in my table of the genera allied to IWelanterius,26 would appear to denote that (as the: eyes are coarsely faceted) they belonged to Psydestis, or to a new genus; but in one of them the rostrum does pass the mesosternum, and the species are so obviously allied (in fact at first they appear to belong to but one species) that it would be absurd to generically separate them. They are less compact than the species of Diethusa, and the second abdominal seg- ment is rather large. In many species of Diethusa some of the alternate interstices of the elytra are elevated, but usually the elevation is of the nature of a ridge or carina, and is shining. In these species the elevation consists of the whole: (16) Proc. Linn. Soc., N.S.W., 1899, p. 200. 309 width of the interstice. The clothing is denser than on other species of I/clanterius. The punctures of the under-surface are practically the same on all three species. On the present species the sutural interstice is strongly elevated from the middle to the apex, the third is similarly elevated from before the middle to the apex, the fifth is. elevated for a less distance, and the elevated part suddenly terminates some distance from the apex; the seventh is also elevated for part of its length. On the basal third the inter-. stices are all much alike. The tooth on each of the front femora is so minute that it is quite invisible from most direc-. tions; on the others it is also small, but being equilaterally triangular is moderately distinct. The mesosternal receptacle is so strongly concave as to leave the middle coxe exposed, but the front margins curve round the coxz, and from the: sides appear as short processes behind them. On nemorhinus the interstices are only moderately elevated, and the elevated parts are confined to the posterior declivity, instead of commencing seme distance before same. The tooth on each hind femur is very strong and acute, on the others it is quite distinct, although smaller. The meso- sternal receptacle is much shallower and much smaller than in lamellatus, and curves less around the middle coxe. Its rostrum is longer and straighter than in lamellatus and leu-- copheus. On leucopheus the elevated parts of the interstices com- mence much as on /amellatus, but are somewhat less strongly elevated, although more so than on nemorhinus, and the- sutural interstice, although elevated above the second, is not as strong posteriorly as is the third, whereas on lamellatus it is quite as strong. The tooth on each front femur is small but distinct, on the middle pair it is acute and fairly large, on the hind pair large and acute (larger than on nemorhinus ). The mesosternal receptacle is intermediate between that of lamellatus and nemorhinus. MELANTERIUS NEMORHINUS, D1. sp. Celour and clothing much as in preceding species. Rostrum long, thin, and almost straight, with clearly-. defined punctures, becoming linear in arrangement towards, and concealed about, base. Scape as long as funicle, inserted two-fifths from apex of rostrum; first joint of funicle dis- tinctly longer than second. Prothorax without trace of a median carina. Hlytra not much wider than prothorax, but. sides and punctures much as in preceding species. Length, 44-5 mm. fHfab.—Queensland: Dalby (Mrs. F. H. Hobler). 310 MELANTERIUS LEUCOPHAUS, N. sp. Colour and clothing much as in the preceding species, but scales of under-surface and legs almost uniformly whitish. Hyes, rostrum, and antenne much as in that species. Prothorax without trace of a median carina. FHlytra much the same, but alternate interstices less conspicuously elevated and seriate punctures somewhat larger. Length, 5 mm. Hab.—New South Wales: Blue Mountains (E. W. Ferguson). There is an allied species from Rockhampton in the Ham- burg Museum, but its alternate interstices are more strongly elevated, abdominal clothing much denser, and hind femora edentate, instead of with a very strong tooth as in the present species. MELANTERIUS LATICORNIS, Nn. sp. Black; rostrum, antenne, and legs of a dingy-ted. Upper-surface almost glabrous; under-surface and legs rather sparsely setose, the sete stouter on metasternum and denser on legs than elsewhere. Hyes widely separated on upper-surface, almost touching on under. Rostrum moderately long and not very thin, sub- gibbous at base; punctures crowded in front of antenne, but’ in linear arrangement behind same. Antenne rather stout; scape inserted one-third from apex of rostrum and the length of funicle; first joint of funicle longer than second, the others regularly increasing in width, club subcontinuous with funicle. Prothoraz almost as long as wide; with dense and rather large and deep, clearly-defined punctures. Zlytra rather long, sides very feebly rounded, base rather lightly trisinuate ; with rows of large suboblong punctures, becoming small pos- teriorly ; interstices rather acutely ridged posteriorly, the lateral ones towards the base as well, but the sutural one nowhere ridged, each with a feeble row of rather small punc- tures. MZetasternum with dense and rather coarse punctures ; episterna unusually narrow. Basal segment of abdomen gently concave in middle; punctures sparser than on metasternum, but quite as large. Femora moderately stout, rather lightly dentate. Length, 34-34 mm. Hab.—Tasmania: Hobart (A. M. Lea); New South Wales (Macleay Museum): Blue Mountains (E. W. Fer- — guson). The funicle is really seven-jointed, but the joints so increase in width, and are so close together that a compound power is necessary to enable their number to be counted. The rostrum is fairly long, but stouter and more rounded than usual ; from the side its base appears to be separated from the head by a feeble notch. Seen from below the scrobes appear 311 to be deep and to meet in the middle at the exact base of the- rostrum, on its lower-surface. The prothoracic punctures are all sharply defined, and no two are really confluent ; but as the Emterspaces between some of them are in very feeble ridges, they have the appearance of being feebly confluent. In anten- nalis, also with stout antennz (and with which it would be: associated in my table), the club is distinctly separated from the funicle, instead of being apparently continuous with it. It differs also in many other respects, but notably in width, size. of punctures, and base of rostrum. The eyes almost meet on the lower-surface, as in .Veomelanterius, but as the rostrum is. not of great length, it appears better to refer the species to Melanterius. The (three) typical specimens are probably all. males. MELANTERIUS MINOR, DN. Sp. Blackish-brown; rostrum, antenne, and legs somewhat paler. Elytra with minute white sete, forming a feeble row on each side of each interstice; under-surface and legs with fairly numerous whitish sete. Eyes separated less than width of base of rostrum. Ros-. trum rather long and thin: with dense punctures, becoming linear in arrangement Behind antenne, and with a narrow median carina. Scape inserted about two-fifths from apex of rostrum and almost the length of funicle; first joint of funicle- longer than second. Prothorax almost as long as wide, apex not much narrower than base; with dense, moderately large, clearly - defined punctures. SHlytra oblong - cordate, sides- parallel on basal half; with rows of suboblong punctures in rather narrow strie; interstices wider than strie, with feeble ridges, becoming acute posteriorly, each with a feeble row of— punctures on each side, sutural interstice with a single irregular~ row of punctures and feebly ridged only on posterior declivity. Basal segment of aeeuers flat in middle. /emora moderately ~ dentate. Length, 2? mm. Hab.—New South Wales: Sydney (A. J. Coates). In some respects close to antennalis, but smaller, narrower, and with the second elytral interstice non-carinate on the basal half. In shape it is something like the preceding, but that species is larger, with very different punctures, rostrum, and eyes. It is the smallest of the genus, except castaneus, which. is much more robust and otherwise different. MELANTERIUS CONFUSUS, nN. sp. Blackish-brown ; antenne and tarsi of a dingy-red. Upper- surface almost glabrous: under-surface with rather sparse: whitish sete, becoming denser on apical segment and on legs. 312 Eyes rather close together; a deep fovea between them. Rostrum moderately long, with clearly-defined punctures in front, becoming linear in arrangement, and leaving three feeble carina behind antennze. Scape inserted about two- fifths from apex of rostrum, somewhat shorter than funicle; ‘basal joint of funicle longer than second. Prothorax with moderately dense and clearly-defined but rather small punc- tures. Hlytra cordate, shoulders and sides rather strongly rounded, base not trisinuate; with rows of moderately large wrinkled punctures, in deep striz; interstices ridged along middle, except about base, the sutural one only posteriorly, ‘with dense rugose punctures. M/etasternwm with sparser punc- ‘tures than usual. Basal segment of abdomen rather lighily depressed in middle. Yemora stout, rather strongly dentate. Length, 45 mm. Hab.—Queensland: Cairns (E. Allen). In many respects close to persimilis, but all the interstices ‘with dense and confused punctures not (except those in the ‘striz) in series. In my table the punctures would also dis- tinguish it from cordipennis, which, moreover, is a consider- ably paler species. The second abdominal segment is rather ‘shorter than is usual in the genus, being distinctly shorter ‘than the two following combined. MELANTERIUS ELLIPTICUS, Nn. sp. @. Blackish-brown; antennze and tarsi paler. Elytra with very minute sete, prothorax with a seta in each punc- ‘ture ; legs with rather dense white sete, the under-surface more sparsely’ clothed. Eyes widely separated. Rostrum rather long and thin; with rather dense punctures in front, becoming linear in arrangement behind antenne, but leaving an impunctate median line from same to base. Scape thin, inserted one-third from apex of rostrum and the length of funicle; first joint of funicle distinctly longer than second. Prothorax not much -wider than long, sides obliquely decreasing in width to apex; with dense clearly-defined punctures of moderate size, becom- ing small about apex. Hlytra closely applied to, and base no wider than prothorax, sides rather strongly rounded; with rows of large oblong punctures, becoming smaller posteriorly ; ‘interstices acutely ridged on apical half, the lateral ones almost to base, with sparse and minute punctures. Basal segment of abdomen flat in middle; third and fourth each with a single row of setiferous punctures across middle. Femora stout, strongly dentate; four front tibiz each with ‘hook starting near summit of apical slope. Length, 44 mm. Hab.—Queensland: Cairns (E. Allen). 313 An elliptic species with the outlines of prothorax and elytra continuous. The prothorax is narrower than in semi-. porosus, its punctures rather denser, and conspicuously dif- ferent in size at base and apex, and elytral interstices more: convex. In general appearance close to rufimanus, but punc- tures of second abdominal segment distinctly larger, and third and fourth each with a conspicuous row; the teeth of the front femora also are no larger (if as large) as those of the middle pair, whereas on that species they are distinctly larger. In this, as in many other species of the genus, the seriate: punctures on the elytra, although rather large, are not sharply defined, and appear more as dilated portions of the striz rather than as isolated punctures. MELANTERIUS MEDIOCRIS, Ni. sp. Blackish-brown ; antennz and claw joint of a dingy-red. Elytra with a row of minute sete on each side of each inter-- stice; under-surface and legs with distinct white sete. Eyes close together. Rostrum rather long and thin; with dense punctures, becoming linear in arrangement behind antenne. Scape inserted about three-sevenths from apex of rostrum, distinctly shorter than funicle; first jot of funicle longer than second. Prothorax moderately transverse, sides strongly rounded; punctures much as on preceding species. Elytra cordate, shoulders and sides strongly rounded; with series of large somewhat distant punctures, becoming smaller posteriorly ; interstices acutely carinated, but not to extreme: base, the sutural one only posteriorly, the next three rather feebly on basal third; each with a somewhat irregular row of small punctures on each side of each ridge. Metasternum and basal segment of abdomen, and part of second segment, with dense and rather coarse punctures; basal segment gently convex in middle. /emora stout, strongly dentate, and each with a granule in emargination. Length, 5 mm. Hab.—Queensland: Cairns (E. Allen). In general appearance somewhat close to strabonis, but larger, second interstice not quite the same and femoral denti- tion less strong. Also close to confusus, but suture and denti- tion different. Also like large specimens of p-rsimilis, but the interstices differently granulate; in that species the inter- stices have, on their outer sides, a granule placed at about the middle of the side of each of the large seriate punctures or fovee, but there are no granules on the inner sides of the interstices. On the present species there are granules on both sides. On the preceding species there are a few granules on the outer sides of the interstices, but their places are usually marked by slight median extensions of the fovee. The elytra, 314 although closely applied to the prothorax, are decidedly wider near the base, so that the outlines are not continuous with ‘those of the prothorax as in the preceding species. The type appears to be a female. Another specimen, evidently also a female, may represent a variety; it differs in having the femora less strongly dentate and without a granule in the ‘emargination. MELANTERIUS MZESTUS, 0. sp. o. Black; rostrum, antennz, legs, and tip of pro- ‘thorax and of elytra reddish. Elytra with a row of small but distinct setz on each side of each interstice; prothorax, under-surface, and legs moderately clothed. Eyes separated almost the width of rostrum at base. Rostrum long and thin, punctures linear in arrangement behind antenne, and leaving a median carina. Scape thin, inserted one-third from apex of rostrum, the length of funicle; first joint of funicle as long as second and third combined.. Prothorax rather strongly transverse; with dense and rather small punctures. Llytra elongate-cordate, base trisinuate, sides moderately rounded; with rather distant punctures, in deep narrow striz; interstices ridged along middle, the first ‘only on posterior declivity, the second to fourth from near middle, the others almost to base, with dense punctures almost as large as those on prothorax but less regular. Basal segment of abdomen somewhat flattened in middle. Femora rather stout, moderately dentate. Length, 34-32 mm. Q. Differs in having the body parts not quite black, the rostrum thinner and slightly longer, with smaller and sparser punctures, less linear in arrangement, and antennz inserted nearer middle; basal segment of abdomen evenly convex, and tibial hooks stronger. Hab.—Queensland: Cunnamulla (H. Hardcastle). In general appearance extremely close to acacie, but second and third interstices of elytra not at all carinate on basal third, punctures of under-surface larger, and the scales in same smaller, rostrum thinner in both sexes, and spur of four front tibie of female commencing halfway down the apical slope, instead of at summit of same. In my table would be associated with imterstetialis, incomptus, and tristis; from wncomptus distinguished by tts considerably narrower form, from the others by its distinctly narrower and longer rostrum, and thinner antenne. The female has a moderately distinct smooth median line on the prothorax, but on the male it is scarcely traceable. Another male from Cunnamulla differs from the type in having the clothing of the prothorax and under-surface distinctly longer, that of the former distinctly rising above the S35 general level, which it does not do on the type. But as I can find no other distinctions it appears desirable to regard it as a variety rather than as a distinct species. MELANTERIUS IMITATOR, 0. sp. ¢. Black; tip of prothorax, antenne, and legs red. Elytra with a fairly distinct row of setz on each side of each interstice; prothoracic clothing not rising to general level, under-surface and legs moderately clothed. Eyes moderately separated. Rostrum long and thin; with dense punctures, becoming coarser towards base, but scarcely linear in arrangement. Scape inserted three-sevenths from apex of rostrum, decidedly shorter than funicle; first joint of funicle as long as second and third combined. Pro- thorax rather strongly transverse; with dense clearly-defined punctures of moderate size. Hlytra oblong-cordate, sides rather feebly rounded, base lightly trisinuate; with rows of rather large distant punctures; interstices acutely ridged, the first only on posterior declivity, the second not on basal sixth, the others almost to extreme base, but the fourth and sixth less acutely than the adjacent ones; each with two somewhat irregular rows of somewhat coarse punctures, becoming smaller and more reguiar posteriorly. Abdomen with rather dense punctures, rather sparser and larger on intercoxal process (which is depressed) than elsewhere. /emora stout, hind ones. moderately, the others lightly dentate. Length, 3 mm. Hab.—South Australia (H. Hacker). In my table would be associated with vulgivagus, to which species, in fact, 1t bears a rather close resemblance; but it is distinguished therefrom by the much less conspicuous denti- tion; the front femora from most directions appear to be edentate, and the tooth even when visible is seen to be ex- tremely small. The eyes are decidedly closer together than in acacie, or in sohtus, to which latter species the elytral clothing might suggest affinity. MELANTERIUS FASCICULATUS, N. sp. Almost or quite black: antennz and tarsi of a dingy- red. Upper-surface with minute setz, under-surface and legs with distinct whitish setz, the four hind trochanters each with a conspicuous fascicle of long golden sete. | Eyes moderately separated. Rostrum moderately long and thin; with rather coarse punctures, becoming linear in arrangement behind antenne, but not leaving distinct carine. Scape inserted about one-third from apex of rostrum, almost the length of funicle; first joint of funicle distinctly longer than second. Prothorax moderately transverse, sides strongly 316 rounded; punctures dense, clearly defined, and not very large. JLlytra elongate-cordate, sides moderately rounded ; with rows of large suboblong punctures, becoming smaller ‘posteriorly ; interstices acutely ridged for most “of their lengths, but the first only on posterior declivity, with a row of distinct punctures on each side of each ridge. Under- surface with dense and coarse punctures; basal segment of abdomen depressed in middle of base, apical segment with a wide, shallow impression. Jemora stout, strongly dentate. Length, 4 mm. Hab.—Queensland: Townsville (H. H. D. Griffith from BE: Doda): A black species of medium size but readily distinguished by the conspicuous fascicles on the trochanters; these, how- ever, may be sexual, as both the specimens before me appear ‘to be males. The front trochanters have each one strong seta, and a similar seta is on each side of the subapical abdominal impression. MELANTERIUS LEGITIMUS, Lea. Two specimens from Mount Wellington 7) probably belong to this species, but differ from the type in having the basal two-thirds of the rostrum tricarinate. On the type the punctures are more or less in rows, but, except for the median carina, the spaces separating the rows are not distinctly -carinated. MELANTERIUS CONGRUUS, Lea. This species has the second abdominal segment fairly large im comparison with most species of Diethusa, and the femora feebly grooved, and so was referred to M/clanterius, despite the ‘density of its clothing. The type is a male, and its front tibie are rather strongly curved, the apical spur is of normal appear- ance, but behind it the apex of the tibia has two ridges (con- verging to the spur), between which the tarsus is placed. The hind tibie are bisinuate, but the apical sinus is short, so that from some directions it appears almost like a notch, the apical spur is stouter and larger than usual, and has a small supple- mentary tcoth or granule on one of its faces. From some direc- ‘tions the basal segment of abdomen appears to have a large depression, of such a shape that its middle runs out narrowly to the apex of the segment. A second male agrees in size and | in all structural details with the type, but the base of its elytra has indistinct spots of brownish scales, and about the middle there are some faint whitish spots. A small (24 mm.) male from Sydney has the front tibie rather more strongly curved, with a stronger spur, the hind - (17) Now first recorded for Tasmania. 317 tibie have also stronger spurs and the apical notch is more pronounced. But the abdominal depression is shallower, and does not run out to a point. The clothing is much as on the type. Another male (8 mm.) has a conspicuous but irregular patch of dark scales at the base of the elytra, and some obscure spots about the middle. A female (the only one known to me) associated with it has identical markings, but differs in having the rostrum somewhat longer and thinner, with punctures of moderate size only at the extreme base (where they are partly concealed), antenne inserted nearer base than apex of rostrum, front and hind tibiz normal, and basal segment of abdomen rather strongly convex. MELANTERIUS MACULATUS, Lea. A specimen from Tasmania differs from the normal form in having the derm of the prothorax and elytra entirely black, instead of a rather dark-brown. MELANTERIUS CONSPICIENDUS, Lea. A specimen from Brisbane is evidently a female of this species. It differs from the type, evidently a male, in being slightly smaller; rostrum longer and thinner, with less evident rows of punctures; antennz inserted not quite so close to apex of rostrum; and basal segment of abdomen convex, instead of depressed, in middle. MELANTERIUS AMPLIPENNIS, Lea (now Dicthusa). The type of this species is a female; it differs from the female of Methusa amplicornis in being smaller and with a considerably longer rostrum. A male of the species has recently been taken at Gosford, and it is undoubtedly extremely close to the male of D. amplicornis, but differs in being much smaller (34 mm. only), with the two apical joints of funicle and the club rather narrower (but still much larger than usual), the legs shorter and stouter, the hind tibie more strongly bisinuate, with the apical sinus decidedly shorter. and deeper, appearing much like a notch; the middle tibie are also dis- tinctly bisinuate instead of arched. The second abdominal segment, however, is slightly shorter than the third, and its sides clasp the sides of that segment exactly as in the male of D. amplicorns. The two species are certainly congeneric, but the differ- ences in the legs of the males and rostra of the females convince me that they are not conspecific, despite the same peculiar antenne and abdomen. As the main distinction between 318 Melanterius and Diethusa lies in the second abdominal seg-- ment, and that segment cannot be used for the two species now under consideration ; and as the clothing is so dense that the: derm is partly hidden, it appears desirable to regard them. both as belonging to Diethusa. DIETHUSA. This genus is unsatisfactorily close to Melanterius. Never- theless, as each is now known to contain many species ( Diethusa 24, Melanterius 45 ; numbers that will probably he more than: doubled), most of which are easily referable to one or the other, it appears desirable to maintain them. The principal features: relied upon to distinguish them are the grooving of the femora and the size of the second abdominal segment. Owing to the clothing, however, it is often difficult to decide as to whether a femur is grooved or not. The size of the second segment, however, is readily seen, but this is a character that sometimes. must be treated in an arbitrary manner, and in two species at least (Diethusa amplicornis and Melanterius amplipennis) is sexually very different. On the whole, however, it appears. desirable to refer all the wide, densely-clothed species with the second segment short to Diethusa. In all the species that have been referred to that genus the clothing is dense, and in the majority of species now standing under Melanterius it is much. less dense, sometimes almost absent, at anyrate on the pro- notum, where each puncture contains but one scale; that usually is depressed below the general level. There are, how- ever, three exceptions to this, w1z., floridus, congrwus, and amplipennis, all of which are commented upon. The peculiar armature of the four front tibiz of some species of Diethusa is not a generic feature; in the females of some species the spur, or tooth, commences at the extreme upper end of the dilated apex of the tibiz, and slightly diverges from the oblique apex; in others it commences half-way down, but in the majority it is terminal, as in the males. DIETHUSA APICALIS, Wi. Sp. Reddish-castaneous; prothorax in parts somewhat infus- cate. Densely clothed with stiff scales, varying from stramineous to ochreous, but uniformly pale on under-surface ;. elytra with a few feeble sooty spots. Rostrum long, thin, and almost parallel-sided; with an impunctate median line from base to apex, with punctures in rows behind antenne. Scape inserted in middle of rostrum, distinctly shorter than funicle; first joint of funicle slightly shorter than second. Prothorax rather lightly transverse ; 319 ‘with dense punctures. JHlytra subcordate, base strongly tri- sinuate; with rows of suboblong punctures, in narrow, deep strie; interstices rather wide, nowhere ridged. Basal seg- ment of abdomen obliquely flattened in middle; apical segment with a wide, shallow impression. Femora rather stout, hind ones moderately, the others very feebly, dentate; front tibie bicalearate at apex, hind pair with apical hook dentate. Length, 34 mm. Hab.—Victoria (National Museum). The clothing is denser and less decumbent than in other species of the genus. The front tibiz are moderately curved at apex, and the apex itself is bicalcarate; the spurs are of uneven size, but start from a common base. The spur of the hind tibie has a distinct triangular tooth, that from some directions appears to be almost as large as the spur itself. ‘The teeth of the four front femora are invisible from most ‘directions. The type is probably a male. DIETHUSA SULFUREA, N. sp. Reddish-castaneous. Densely clothed with sulphur- ‘coloured scales, in places with a golden-lustre: paler (but scarcely white) on under-surface and legs. Rostrum not very long, parallel-sided to insertion of antenne, thence narrowed to apex; with dense punctures concealed near base. Scape stout, inserted two-fifths from apex of rostrum, distinctly shorter than funicle; first joint of funicle as long as second and third combined, third to seventh transverse. Prothorax moderately transverse, punc- tures normally quite concealed. Llytra subcordate, base moderately trisinuate; with rows of partially-concealed punctures, in narrow striz; interstices irregular, but no- where ridged. Basal segment of abdomen gently concave in middle; apical with a wide impression. Jemora moderately stout, edentate; tibize with apical spurs minute. Length, 34 mm. Hab.—Queensland: Cunnamulla (H. Hardcastle). Readily distinguished from others of the genus by the inequalities of the elytra and the sulphur-coloured clothing. ‘The elytra are nowhere supplied with distinct tubercles, but have numerous slight swellings, giving the surface an uneven appearance; the second interstice is rather suddenly dilated about the base, the third is narrowest at the base, and widest close to same. The punctures in the strie are probably of fairly large size, although appearing rather small; but. the species being a very distinct one, and the type unique, the derm has not been abraded to expose their full size. 320 LYBZBA AMPLICORNIS, Lea (now Diethusa). The types of this species are males. Two females from the Victorian Alps appear to belong to the species. They differ from the types in being slightly larger, rostrum thinner and fully the length of prothorax, with smaller and less crowded punctures, antenne inserted rather more distant from apex of rostrum, two apical joints of funicle and the club distinctly narrower (although of larger size than usual), four front tibie each more dilated at apex, with a narrow tooth or spine commencing at the upper apex and slightly diverging from the oblique line of apex (much as in the females of J. floridus and D. blackburni); second segment of abdomen at its greatest length in middle, where the length is about once and one-half that of the third segment, and with each side less conspicuously embracing the side of the third. LYBZBA SQUAMIVARIA, Lea (now Diethusa). When describing this species I was mistaken as to the sexes; the specimens noted as probably being males are really females; in addition to the differences of the front tibie the males differ from the females in having the rostrum slightly shorter, with the antennz inserted rather closer to the apex, and the metasternum and basal segment of abdomen with a wide shallow depression common to both. NEOMELANTERIUS SUBTUBERCULATUS ) Lea. The type of this species is a male; a female (from Com- boyne in New South Wales) differs in having the rostrum considerably longer (when at rest the tip is actually upon the base of the abdomen instead of near it), the apical half shin- ing, with smaller and less crowded punctures, and basal half more feebly carinated. The antenne, instead of being in- serted at about one-third from apex of rostrum, are inserted almost in the exact middle. A female, from the Cairns district, apparently. belongs to the species, but has the elytra castaneous, and their punc- tures larger and more clearly defined than on the type, or than on the Comboyne female. MECHISTOCERUS SIMILIS, 0. sp. d. Black; antenne and tarsi red. Densely clothed. Head with coarse partially-concealed punctures. Ocular fovea subtriangular. Rostrum long and thin; basal third with concealed punctures and three narrow ridges, elsewhere shining and with minute punctures. Scape inserted one-third from apex of rostrum; second joint of funicle distinctly 321 longer than first. Prothorax moderately transverse, sides strongly rounded; with a narrow median carina; with fairly large punctures, but each almost concealed by its contained scale. Hlytra rather short, subcordate, base trisinuate and about one-fourth wider than prothorax; with rows of large partially-concealed punctures; with rather numerous granules about base, and a few elsewhere. Metasternum rather short; with a deep and rather wide median impression dilated at both ends; near middle with a few large punctures, then with more numerous but smaller ones; each episterna with a conspicuous row. Abdomen with basal segment flat in middle ; with sparse and distinct, but comparatively small, punctures ; apical segment with dense punctures. Legs long; femora acutely dentate, hind pair distinctly passing apex of elytra. Length, 7-74 mm. Q. Differs in being larger (9-10 mm.), rostrum longer, thinner, without basal ridges, and with smaller and sparser basal punctures; antennze inserted distinctly nearer the middle of rostrum, basal segment of abdomen evenly convex and hind femora just passing apex of elytra. Hab.—Queensland: Cairns (C. French) ; Little Mulgrave River (H. Hacker and H. H. D. Griffith) ; Kuranda (Hacker). Four of the specimens under examination have the basal segment of abdomen flattened; these I believe to be males; five others have that segment convex, and are presumably females. Jf the sexes are as presumed, than the species is readily distinguished from denticulatus by the very different front legs; in any case the clothing of the prothorax should be distinctive. In my table of the genus would be associated with mastersi, which is a wider species, with denser and other- wise different clothing, and front femora less conspicuously dentate. From dispar, to which at first it appears to be closer, it differs in the very different clothing and punctures of prothorax; the insertion of antennz also is different, and the femoral dentition is weaker. On the elytra the clothing is mostly of a pale-brown, variegated with irregularly dis- tributed sooty spots, and with some paler ones, the latter more or less congested into two feeble fasciz, one at apical third, and the other (sometimes appearing as a feeble V) at basal third. Each interstice has a feeble row of stout scales, and there is a similar scale in each seriate puncture. On the prothorax the scales are large and individually distinct (except at apex, where they are small and crowded), many are sooty, but there is a distinct line of pale scales along middle, and some irregular lines on sides. On the under-surface the scales are rather sparse, mostly thin and pale, but with some sooty ones on the abdomen. The legs are very densely clothed. L 322 MECHISTOCERUS LANGUIDUS, Lea. The type of this species was probably somewhat abraded, as a female now before me (from Cairns) evidently is in per- fect condition and has the peculiar scales (much as on the elytra, except that they are slightly larger) denser on the sides and front of prothorax than elsewhere; but amongst them may be noticed sete similar to those on the type. The female differs from the male in having the rostrum longer, thinner, paler, and more evenly curved, and only the basal third squamose; the scape inserted somewhat nearer the middle of rostrum; the front legs shorter, and their tibie without a conspicuous fringe. MECHISTOCERUS DENTICULATUS, Pasc. _ Of the male of this species Pascoe stated “‘tibiis anticis denticulis in series duas ordinatis.’? Three males (two from the vicinity of Cairns) of the species before me each have the teeth on the front tibiz so arranged that when a tibia is viewed directly from above a conspicuous fringe of teeth is visible on each side; but in addition there are a few teeth forming an irregular third row. These specimens also have three feeble pale longitudinal stripes on the prothorax. Var. MINOR, n. var. Four males (also from Cairns) differ from the normal form in being much smaller (33-6 mm.) and with the fringes of teeth reduced in size, so that when a front tibia is viewed from above only one row of teeth is visible at a time, and they have no remnants of a third row. These specimens also are entirely devoid of longitudinal markings on the prothorax. MECHISTOCERUS CANCELLATUS, Lea (?%). There are two specimens before me (from Cairns and Kuranda) which, with some doubt, I refer to this species. They differ from the types in having the basal segment of abdomen gently concave, and with large punctures at base only, elsewhere and the second segment with small punctures, usually concealed by the sete they bear. The punctures on the metasternum are also smaller. They are probably males, and the types are probably females. They have the abdominal punctures much as in punctiventris, but all the femora are. strongly dentate. PERISSOPS MEDIONOTATUS, N. sp. d. Black; antenne of a dingy-red. Moderately clothed with more or less ochreous scales, closely applied to derm, and in places condensed into feeble spots. Head strongly convex, with a feeble median line, ocular 323 fovea deep but not very large. Eyes finely faceted. Rostrum rather wide, notched on each side of base; with dense punc- tures, not very large in front of antennz, coarser and rugose behind same, and leaving three feeble ridges. Scape inserted two-fifths from apex of rostrum, not much shorter than funicle. Prothorazx moderately transverse, subconical; with numerous small punctures, the sides with large unevenly dis- tributed ones. JZlytra strongly convex, outlines continuous with those of prothorax; with rows of rather small punctures in feeble striz, sutural interstice wide, strongly elevated to middle, with dense transverse granules to beyond the middle, sparser ones for a shorter distance on second, and a few on third. Femora stout, strongly dentate; tibie compressed, lightly curved, the front ones feebly bisinuate on lower- surface. Length, 84-12 mm. Q. Differs in being wider and much less convex, especially in middle of elytra, rostrum thinner, shining, with much smaller and sparser punctures, and without subbasal ridges; antennz inserted not quite so close to apex of rostrum; basal segment of abdomen gently convex, instead of feebly concave in middle, and bisinuation of front tibize less pronounced. Hab.—Queensland: Mackay (C. French). Close to mucidus, but with more uniform clothing be- tween the spots, these being less distinct, except that on each elytron there is a conspicuous pale submedian spot at a posi- tion where (on mucidus) the spotting is less noticeable. The head has three spots, but the parts between them are also moderately clothed. The abdomen is moderately clothed, but the scales are denser in parts, so that it appears to be feebly trivirgate. On the prothorax there are some sooty scales scat- tered about. The derm is really of a deep-black, but the clothing causes it to appear a dingy-brown. The fifth, ninth, and tenth striz are fairly deep near the base of the elytra, but do not extend to the base itself. PERISSOPS TARSALIS, 0. sp. dg. Black. Densely clothed in parts. Head densely and rather coarsely punctured; ocular fovea indistinct. Eyes large and finely faceted. Rostrum rather long, thin, and moderately curved; basal two-thirds with dense and coarse punctures, and a eee eS median carina, elsewhere smooth and with minute punctures. Prothorax moderately transverse, subconical; with small and rather dense punctures, and with fairly large ones, becoming almost regular on the sides. Hlytra strongly convex, outlines subcon- tinuous with those of prothorax; with rows of large deep L2 324 punctures, obscured where the clothing is very dense; suture with a few feeble granules. Basal segment of abdomen feebly depressed in middle. Front legs much longer than the others ; all femora strongly dentate; tibia compressed, somewhat curved, the middle ones angular near outer base. Length, 105 mm. Hab.—Queensland: Rockhampton (R. Ilhdge). The type is dirty, evidently much abraded, and without antenne (except for one scape), but the long front legs with curiously clothed front tarsi render it very distinct, although these characters are probably confined to the male. In my table, on account of the middle tibiz, it would be associated with intricatus and intricatior, but it has little in common with those species. On each elytron there is a very con- spicuous spot of short scales, densely compacted together, from the second interstice to the fifth, slightly beyond the middle, and another near the base from the third to the shoulder. On the prothorax there is a smaller spot on each side of the middle towards apex; these spots are separated on the type, but possibly are normally connected. On the rest of the upper-surface the clothing appears to have been mostly ochreous or whitish. The front tarsi have a very conspicuous fringe of long hairs on each side, the hairs being considerably longer than the joints are wide. Possibly on specimens in good condition the spots noted are eye-like in character and variegated, but on the type they have a muddy appearance. PERISSOPS PISCICORPUS, N. sp. Of a dingy-red, in parts obscurely stained with black. Densely clothed with soft, pale, fawn-coloured scales; on the elytra somewhat variegated. Head with punctures normally concealed; inter-ocular fovea narrow. Eyes with rather coarse facets. Rostrum wide and feebly curved, basal third with sculpture concealed, then with rather dense and coarse punctures to antenne, in front of same shining and with small but clearly-defined punctures. Scape inserted in middle of rostrum, distinctly shorter than funicle. Prothorax moderately transverse, apex more than half the width of base; punctures normally more or less con- cealed; with a feeble median carina. Hlytra moderately convex, distinctly, but not much, wider than prothorax, parallel-sided to beyond the middle; with rows of large partially-concealed punctures, becoming small posteriorly ; with some small more or less concealed granules. Under- surface with dense partially-concealed punctures. - Basal segment of abdomen feebly convex, its apex feebly incurved 325 to middle. Femora stout, moderately dentate; tibie gently compressed, somewhat angular near outer base. Length, 8 mm. Hab.—Queensland: Cairns (E. Allen). The density of the clothing is unusual in the genus. In general appearance close to some of the densely-clothed specimens of granulatus, but without supplementary teeth in the femoral emargination and middle tibie angular near ex- ternal base, as in albonotatus, imtricatus, and intricatior, although with little else in common with those species. On each elytron of the type there is a small angular spot of sooty scales beyond the middle, and a few much smaller ones else- where; in places also there are feeble irregular spots or stripes of whitish scales. Many of the scales, especially on the abdomen, have a peculiar rounded appearance. The clothing on the head is dense and uniform. PERISSOPS GRANICOLLIS, Nn. sp. 3. Black, in places obscurely diluted with red; antenne and tarsi reddish. Densely clothed with more or less ochreous scales, interspersed with a few white ones; each elytron with a large, subtriangular, medio-lateral patch of sooty scales. Head with moderately dense partially-concealed punc- tures; a narrow impression behind each eye. Eyes large and rather close together. Rostrum about the length of prothorax and rather thin, moderately curved, almost parallel-sided ; with numerous rather small but clearly-defined punctures, becoming larger and concealed on sides about base. Scape inserted about two-fifths from apex of rostrum, slightly shorter than funicle. Prothorax moderately transverse, sides strongly rounded, base bisinuate and almost twice the width of apex; with numerous shining granules, more conspicuous on sides than elsewhere; with a short but distinct median carina; punctures concealed. Llytra cordate, distinctly wider than prothorax, sides parallel to about the middle; with rows of large more or less concealed punctures. Mesosternal re- ceptacle rather short, walls rather thin and widely U-shaped. Basal segment of abdomen almost as long as three following combined, rather flat in middle, its suture with second straight. Legs rather long; femora strongly dentate, hind pair extending to tip of elytra; tibie thin. Length, 54-64 mm. Q. Differs in having the rostrum distinctly longer and thinner, with smaller and sparser punctures; scape inserted almcst in middle of rostrum, and basal segment of abdomen convex in middle. fHlab.— Queensland: Cooktown (H. W. Brown). 326 This species might have been, with almost equal pro- priety, referred to Tyrtewosus. But, as it is obviously very close to Perissops robiginosus, it has been referred to the genus of the latter. From that species it differs in its smaller size, decidedly thinner tibie, and different mesosternal receptacle. In robzginosus (although not mentioned in the original description) the base of the receptacle has a small tubercle on each side, so that it appears to be bilobed (this appearance, however, is sometimes obscured by scales), and the front portion rises rather abruptly. In the present species the receptacle has a shorter and evenly-rounded or truncate base, and is decidedly less elevated. If the species was re- garded as a T'yrtcosus it would be, in my second table of that genus, associated with pardalis, from which it is abundantly distinct by the medio-lateral dark triangles; these are some- times composed entirely of dark scales, but on some specimens a few ochreous ones are on them. The elytral interstices appear, in places, like rows of granules through the clothing, and a few granules are really present; but the interstices themselves are transversely impressed in numerous places, so that, on abrasion, they appear like ridges many times interrupted. PERISSOPS GRANULATUS, Lea. This species is fairly common on fig-trees in the coastal districts of New South Wales and Queensland. The types were partly abraded; on fresh specimens the clothing, mostly ashen or subochreous, is in parts so dense as to entirely conceal the derm; but usually there is an irregular dark fascia just beyond the middle of the elytra. The prothoracic granules on fresh specimens are indistinct from behind, but distinct from in front. In general appearance some specimens are very close to robiginosus, but that species is without supple- mentary teeth or granules in the femoral emarginations. PERISSOPS MULTIMACULATUS, Lea. Three specimens, from the Coen district of North Queens- land, appear to represent a variety of this species. They differ from the types in having the derm darker (almost or quite black) and the elytra slightly less convex. The female (the female of the typical form is as yet undescribed) differs from the male in having the rostrum longer, thinner, with much smaller punctures, and with the antennz inserted rather more distant from the apex. PERISSOPS ALBONOTATUS, Lea. The type of this species is evidently much abraded, and a specimen (from the Tweed River) now before me is evidently he 327 in perfect condition. - On its upper-surface the pale markings consist of a medio-apical stripe on prothorax, a latero-basal mark, something like an h or k on the right side (and, of course, reversed on the left), and many spots on the elytra (on the type it was stated that there were about fifteen on each elytron, but on the present one there are at least thirty on each), a few of which extend across several interstices, and one on each side near apex is rather elongate. The spaces between the spots are clothed with minute scales, usually more or less brown or sooty. The third interstice is distinctly elevated near the base and has there numerous transverse ridges; similar but less distinct ridges are on the suture and even less distinct ones on some of the other interstices. Genus OrocHLESIS, Pascoe. (18) Queenslandica, Lea.(9) There is before me a Yule Island specimen (taken by d’Albertis) and sent by Dr. Gestro as O. annularis,(2 Pasc., although it differs slightly from the original description. Of the conspicuous apical spot Pascoe says ‘‘saturate vinosa, albido-marginata’’ and ‘“‘the spot is free from scales, and has, although opaque, a somewhat velvety appearance.’’ On the Yule Island specimen the spot is but feebly margined, and the spot itself is really composed of blackish scales, so closely compacted that it is only from certain directions, and in cer- tain lights, that they can be seen to be scales. If Dr. Gestro’s Specimen is correctly named, as it appears to be, the original figures (plate viu., figures 2 and 2a) are not very happy ones. They, in fact, led me to believe that the genus was one of the allies of Psepholax, although certainly Pascoe noted it as allied to Perissops. The genus, however, is undoubtedly synonymous with Queenslandica, and the latter name must therefore fall. _ OROCHLESIS POSTICALIS, Lea (Quweenslandica). This species is extremely close to annularis, but differs from the description in having the subapical spot not at all margined by white scales; it is quite possibly synonymous, but the figures given of annularis would give a very mis- leading idea of it.

(20) O. annularis must be regarded as the typical species of its genus, as it was the first one described, and the only one figured by Pascoe. 328 OROCHLESIS MUNDA, Lea (Queenslandica). The clothing of this species is somewhat variable; on the elytra there is usually a large V-shaped patch, where the scales are paler than elsewhere and bounded behind by sooty scales. The V commences on each shoulder and terminates on the suture slightly beyond the middle; it may be some- times sharply defined and thin, or the whole of the scales enclosed by it may be pale. There are usually a few small granules on the suture near the base, but they are sometimes concealed by the scales. OROCHLESIS DELTA, Nl. sp. Black; antenne and tarsi reddish. Densely clothed with light-brown or fawn-coloured scales, elytra with a velvety, subapical, triangular patch of blackish scales. Under-surface with mostly whitish scales. Head with dense concealed punctures. Rostrum rather stout, decreasing in width from base to antenne, and then parallel-sided; basal third with coarse concealed punctures, elsewhere with small crowded ones, except on a short and feeble median line. Antenne stout, inserted about two-fifths from apex of rostrum. Prothorax strongly transverse, sides strongly rounded, apex less than half the width of base: with dense punctures, each covered by a scale. JLiytra closely applied to and scarcely wider than prothorax, parallel-sided to near apex, which is widely rounded; with rows of large punctures, in light striz, the striz fairly distinct, but pune- tures almost entirely concealed; with a few granules on suture © near base. Under-surface with fairly large punctures, a single row across each of third and fourth segments of abdomen; and a single row on each metasternal episterna. /emora moderately long, strongly grooved, and edentate. Length, 54 mm. Hab.—Queensland: Cape York (H. Elgner). Allied to posticalis, but readily distinguished by the sub- apical spot, which is almost in the shape of an equilateral triangle. On the prothorax the scales are of large size, much larger than those on elytra, and a few of them are white: but on the metasternum and two basal segments of abdomen they are almost as large. The tip of the scape and the joints of the funicle are supplied with long straggling hairs. The type is probably a male. EVANIOCIS, 0. g. Head fairly large. Eyes moderately large, coarsely faceted. Rostrum not very long and rather wide, feebly curved. Antenne rather stout, inserted about middle of Sr = ee 329 rostrum; scape rather short; funicle with two basal joints elongate, the others strongly transverse and close together ; club elongate-elliptic, subcontinuous with funicle, joints indis- tinct. Prothorax transverse, sides rounded, apex produced. Scutellum distinct. Llytra closely applied to and very little wider than prothorax, base feebly trisinuate. Pectoral canal deep and wide, terminated just behind front coxe. Meso- sternal receptacle rather strongly raised, emargination semi- circular, cavernous. Metasternum slightly shorter than the following segment; episterna rather large. Abdomen with first segment as long as second and third combined, its apex lightly incurved to middle, second slightly longer than third and fourth combined. JLegs rather short; femora dentate and feebly grooved; tibize straight, feebly dentate near outer base. The genus is of somewhat doubtful position, but for the present may be placed near J'epperva, from which it differs in its coarsely faceted eyes and elytra not separately rounded at base. Its antennze and tibiz, however, are somewhat similar. In some respects it seems close to Phlwoglymma, from which it differs in the antenne, eyes, and mesosternal receptacle. In the table of genera allied to Cryptor- hynchus 1) would be associated with Hyperiosoma and Sympediosoma, whose antennz and tibiz are very different. Rostrum lightly but distinctly curved... ellipticus Wostrum almost straight .... ... ........ albicans EVANIOCIS ELLIPTICUS, n. sp. Very dark-brown; antenne and tarsi somewhat paler. Densely clothed with somewhat fawn-coloured scales, but in places becoming sooty. Head rather strongly convex, punctures concealed. Rostrum scarcely as long as prothorax, lightly but distinctly curved, sides lightly incurved to middle; with dense punctures partially-concealed on apical half, almost entirely so on basal half. Scape inserted in middle of rostrum. Prothorax moderately transverse, subconical, base bisinuate and twice the width of apex; with dense normally-concealed punctures. Hlytra oblong-cordate, about twice as long as wide; with rows of large partially-concealed punctures becoming smaller posteriorly; third interstice slightly elevated and thickened near base. Under-surface with dense normally-concealed punctures. /emora rather lightly dentate, hind pair not extending to apical segment. Length, 54 mm. Hab.—Queensland: Cairns (E. Allen). (21) Proc. Linn. Soc., N.S.W., 1907, pp. 401-403. 330 On the prothorax the scales have a somewhat sooty appearance on four spots across the middle, and on two at base and two at apex, but the four latter are very feeble. On the elytra the sooty scales occupy most of the basal two-thirds, and form two small spots on the posterior declivity. The head is mostly clothed with sooty scales. On the under-surface the clothing is dense; there are a few white scales on the sterna, but sooty ones are absent. Nearly all the pale scales (except on the legs) are quite circular, this being especially noticeable on the under-surface. From certain directions the small tooth, near the outer base of each tibia, is fairly distinct, but it is more or less concealed by the clothing. EVANIOCIS ALBICANS, Nn. sp. Blackish-brown; antenne and tarsi of a dingy-red. Densely clothed with white scales; with a few sooty ones scat- tered about on head and prothorax; but head with a large, irregular, sooty blotch. Head with dense concealed punctures. Rostrum almost perfectly straight, slightly dilated near base, elsewhere parallel-sided; basal third with coarse concealed punctures, elsewhere shining and with minute punctures. Scape inserted slightly nearer base than apex of rostrum. Prothorax sub- conical, very little wider than long; with dense normally- concealed punctures of uniform size. Hlytra with outlines and sculpture as in preceding species. Under-surface with dense normally-concealed punctures. Femora very feebly dentate. Length, 64 mm. Hab.—Queensland: Kuranda (G. E. Bryant). The outlines are much as in the preceding species, but the clothing is very different, the four hind tibie are more distinctly dentate near the outer base, and the rostrum is almost quite straight. The dentition of the four hind femora is very feeble, and could easily be overlooked, whilst of the front pair it is so very small and obscured by clothing that it almost reaches the vanishing point. TYRTZOSUS TRIANGULIFERUS, Nl. Sp. 3. Of a dingy piceous-brown or black, in places more. or less distinctly diluted with red; antennz and tarsi reddish. Prothorax with scales varying from ashen to ochreous, and usually somewhat lineate in arrangement. Elytra with rather dense ashen-grey scales, but absent from a large subtriangular space on each side, the interstices with more or less regular rows of ochreous scales, but none on dark lateral spaces. 331 Head with front concave and coarsely punctured. Eyes moderately close together. Rostrum moderately long; basal half with very coarse punctures, and with a very feeble ridge, apical half with sharply-defined punctures. Prothorax almost twice as wide as long, sides rounded and feebly increasing in width to near apex, and then suddenly and strongly narrowed so that the apex is only half the width of the base; with large round punctures crowded together but usually nowhere confluent; with a strongly elevated, narrow, median carina. Elytra oblong-cordate, no wider than widest part of pro- thorax; with rows of large deep punctures in feeble striz, and becoming smaller posteriorly; third, fifth, and seventh interstices distinctly raised, and, as some of the others, with partially - concealed squamiferous granules. Metasternwm with a moderate and interrupted ridge on each side between coxe; episterna each with a continuous row of strong punc- tures. Abdomen with first segment feebly concave, and some- what shorter than usual; third and fourth each with a semi- double row of punctures across middle. Legs moderately stout; femora strongly dentate; all tibiz somewhat thin, lightly curved, and not dilated to apex. Length, 4-64 mm. Q. Differs in having the rostrum longer, thinner, more shining, and with smaller and sparser punctures, prothorax less dilated in front, with its widest portion nearer base than apex and less than width of elytra; and basal segment of abdomen moderately convex. Hab.—Queensland: Cairns (E. Allen); Little Mulgrave River (H. Hacker and H. H. D. Griffith from Horace W. Brown) ; New South Wales: Comboyne (W. H. Muldoon). A rather distinct species on account of the prothorax of the male. The side of each elytron has a subtriangular dark patch, largely, but not entirely, due to absence of ashen scales ; the few scales present on it are all sooty, the patch usually extends to the fifth interstice, but sometimes to the second, it commences on the shoulder, and terminates level with the fourth abdominal segment, or thereabouts. On some speci- mens there appear to be four longitudinal stripes on the pro- thorax, and one transverse one, but the linear arrangement is more or less broken up. The depression behind each eye is unusually deep, and the two are dilated till they meet in front, causing the whole front of the head to appear concave, with a quadrisinuate forehead, as in many of the allies of Poropterus. In subopacus it is somewhat similar but less pronounced. The elytral punctures, although large, are partially concealed by the clothing, but on the sides their full extent is usually distinct. 332 TYRTZOSUS SQUAMIVARIUS, Nn. sp. Sooty-black, in parts obscurely diluted with red; antenne and tarsi reddish. Irregularly clothed with scales varying from white to sooty. Head depressed, and with coarse punctures and a median carina in front. ostrwm moderately long, with coarse punc- tures on basal half, apical half with much smaller but more sharply-defined ones, sparser between antennz than elsewhere. Prothorax with sides strongly rounded; with rather large, round, deep, non-confluent punctures, becoming smaller to- wards apex; with a strong, narrow, continuous median carina. LHlytra oblong-cordate, shoulders distinctly wider than prothorax; with rows of large and somewhat distant punctures, in rather feeble strie; alternate interstices dis- tinctly elevated, and with partially-concealed granules. Meta- sternum on each side between coxze with an oblique ridge, very feeble in front, but strong posteriorly; episterna each with a continuous row of strong punctures. Abdomen with a single row of punctures across each of the third and fourth segments. Legs stout; femora strongly dentate; all tibie thin and not dilated to apex. Length, 64-64 mm. Hab.—New South Wales: Illawarra (H. W. Cox); Tweed River (H. W. Brown). The sooty scales are fairly numerous, but indistinct on account of their close resemblance to the derm. On each of the two specimens under examination there is a thin and more or less oblique stripe of snowy scales, starting from near the shoulder, and terminated at the third interstice. On the prothorax there are three feeble longitudinal stripes of whitish (sometimes ochreous) scales, and one transverse stripe. On the elytra (especially about the shoulders and apex) many of the scales are more or less reddish-ochreous. On the under- surface the whitish and ochreous scales are mostly confined to the middle parts. The legs are clothed with numerous whitish setae. The depression on the head is quite as large as on the preceding species, but is not so sharply defined posteriorly. As the basal segment of the abdomen is gently convex on each, the types are probably females. TYRT#OSUS PULCHER, Nn. sp. 3. Jet-black, front of prothorax diluted with red; antenne and tarsi reddish. Clothing irregular in distribution and variously coloured. Head with rather small and sparse punctures. Eyes larger and rather closer together than usual, a narrow im- pression behind each. Rostrum moderately long, basal 333 portion with moderately large and rather dense punctures, small elsewhere. Club rather long. Prothorax decidedly transverse, sides moderately rounded, base strongly bisinuate ; with moderately dense but comparatively small punctures, becoming very small at apex; median carina entirely absent. Elytra not much wider than prothorax, almost parallel-sided to near apex; with rows of large deep punctures, becoming smaller posteriorly, in feeble striz near base, but striae more distinct posteriorly; alternate interstices elevated, the third very strongly so, and with transverse granules on basal fourth. Metasternum rather feebly ridged on each side between coxe, episterna each with a continuous row of punctures. Abdomen with basal segment flattened in middle, third and fourth with rather dense setiferous punctures, not in rows. Legs stout; femora rather strongly dentate; tibiae compressed, somewhat curved, rather narrowed to apex, punctures very small and not in conspicuous strie. Length, 6 mm. Q. Differs in having rostrum somewhat longer and thinner (especially towards apex), shining, with smaller and sparser punctures; antennez inserted not quite so close to apex of rostrum, and basal segment of abdomen moderately convex. Hab.—Queensland: Coen River (H. Hacker). At first sight apparently belonging to Perissops, but the eyes are coarsely faceted and abdominal sutures straight. This and several other species of the genus with alternate inter- stices conspicuously elevated look as if they might belong to Celosternus, but their femora are unidentate. The metallic clothing is alynost unique in the Australian members of the subfamily. On the prothorax the clothing varies from thin sete to fairly stout scales, and in colour from white to sooty, the pale scales (some of which have a purplish lustre) are more or less condensed into three feeble longitudinal stripes, on each side in front there is a small spot of white scales with a golden lustre. On the elytra there are two very irregular fascie of pale scales, a feeble one at basal third, irregularly traceable on to shoulders, and a wider one at summit of posterior declivity; the pale scales from some directions appear to be almost stramineous in colour, but they vary from almost every point of view from red, to purple, and green, and golden-green. From some directions also some of the interstices have a greenish lustre, this being due to minute scales that, individually, are almost too small to be seen under a lens. The under-surface and legs are clothed with whitish sete. The prothoracic punctures (where not obscured by clothing) look as if each had been punched in. 304 TyRT#OSUS MIXTUS, 0. sp. 3. Dark reddish-brown, in places black or blackish ; antenne and tarsi reddish. Rather densely clothed with somewhat fawn-coloured scales, almost uniform on under- surface and legs, but variegated with white and sooty on upper-surface; elytral interstices with feeble rows of stout scales. Head with dense and rather coarse punctures. Eyes widely separated, a narrow depression behind each. Rostrum rather short, wide, and feebly curved; with coarse’and dense punctures partially concealed towards base. Antennz rather short, inserted almost at exact middle of rostrum. Prothoraz slightly wider than long, sides strongly rounded; with dense, moderately large, round, deep, non-confluent punctures; median carina absent. Hlytra not much wider than pro- thorax, long and parallel-sided to near apex, without sub- humeral notches; with rows of fairly large, deep, oblong punctures, becoming small posteriorly and somewhat rounded on sides, interstices much wider than punctures, and each with a more or less concealed row of granules. Metasternum with a rather feeble ridge on each side between coxz; episterna each with a continuous row of punctures, but becoming double posteriorly. Abdomen with first segment not much longer than second, depressed in middle, its apex rather strongly incurved to middle; third and fourth with dense squamiferous punctures. Legs stout; femora strongly and acutely dentate ; all tibize bisinuate on lower-surface, and not dilated to apex. Length, 54 mm. Q. Differs in having the rostrum slightly longer and thinner, with scales only at extreme base, elsewhere shining and with small but clearly-defined punctures, and basal seg- ment of abdomen moderately convex. Hab.—Queensland: Mount Tambourine (H. J. Carter). Close to brewrostris, but with two conspicuous rows of squamiferous punctures on the hind portion of the meta- sternal episterna, and elytra with whitish scales in parts, and without the preapical callus on each marked, although there is a whitish spot immediately behind it on the male, but not on the female. The sooty scales are distributed in irregular spots and patches; on the elytra there is a vague whitish fascia at the basal third, and remnants of another at summit of the posterior declivity. Some specimens, from the Tweed River and Bundaberg, indicate that this species is somewhat variable in size and markings. They are all smaller (4-4§ mm.) than the types, and have the dark scales on the upper-surface forming four or more spots on the prothorax, and three irregular mottlings 339 on the elytra: one at the base, one near the apex, and one (looking like a fascia irregularly broken up) across the middle. The subbasal white spot on each elytron may be very con- spicuous and extending across five interstices, or very feeble (on one specimen absent). On several specimens there are distinct white spots intermingled with the subapical dark ones. TyRTHOSUS MACROPS, Nn. sp. 3d. Deep-black; antenne and tarsi reddish. Densely clothed with sooty, variegated with snowy-white, scales. Head with dense normally-concealed punctures. LHyes larger and closer together than usual. Rostrum rather long and thin, but sides dilated about base; basal third with coarse and dense punctures, elsewhere with fairly dense but much smaller and clearly-defined ones. Antennz inserted distinctly nearer to base than to apex of rostrum; scape about half the length of funicle and club combined. Prothoraz almost twice as wide as long, sides strongly rounded, apex more than half the width of base; with dense, round, non- confluent punctures; without median carina. Elytra sub- cordate, base trisinuate, and very little wider than prothorax, sides strongly rounded. Jfetasternwm with a feeble ridge on each side between coxe; punctures of episterna not inter- rupted. Abdomen with dense squamiferous punctures on third and fourth segments, forming two rows on each across middle, first segment as long as third and fourth combined, flat in middle and its apex perfectly straight. Legs stout; femora strongly and acutely dentate; tibize lightly narrowed to apex. Length, 3-4} mm. Q. Differs in having rostrum longer, thinner, and with smaller punctures, and basal segment of abdomen gently convex. Hab.—Queensland: Coen River (H. Hacker); Cairns (E. Allen). At first sight apparently belonging to Neodecilaus, but the eyes are coarsely faceted, and femora strongly dentate. The mesosternal receptacle at first appears different to that of others of the genus, but this is due more to its clothing - than to much real difference in shape. The insertion of antennz is also at variance with others; the clothing is denser and the individual scales larger than usual. The white scales are distributed sparsely on the upper-surface, but are con- densed to form three (or one) longitudinal line on the pro- thorax, and a short stripe on the fourth interstice posteriorly ; they almost uniformly clothe the under-surface, and are fairly dense on the under parts of the legs. Before abrasion the interstices appear to be much wider than the seriate punctures, 336 these usually being traceable only by their contained scales, but on abrasion they are seen (except on the posterior declivity) to be large, and almost, in places quite, as wide as the interstices; these also are seen to have feeble granules that are normally quite concealed. TYRTZOSUS BIFASCIATUS, Nn. Sp. d. Black, in places sometimes obscurely diluted with red; antenne and tarsi reddish. Upper-surface with dingy- brown or sooty scales, seldom rising to general level. Elytra with a distinct but irregular fascia of soft white scales at basal third, remnants of another at summit of posterior declivity, and with two apical spots. Under-surface and legs with more or less whitish scales and sete. Head with coarse crowded punctures in front, becoming smaller posteriorly. Eyes separated the width of base of rostrum, a partially-concealed depression behind each. Rostrum rather short and stout, feebly dilated to apex; with coarse crowded punctures quite as large at apex as at base. Club rather larger than usual. /Prothorax strongly trans- verse; sides of basal three-fourths rather lightly rounded, then suddenly narrowed, apex less than half the width of base; with dense, and rather large, round, deep, non- confluent punctures; median carina rather feeble and irregular but traceable throughout. Zlytra elongate-cordate, not much wider than prothorax, basal half parallel-sided, subhumeral incurvature very feeble; with rows of large punc- tures, each of which is separated by a depressed transverse ridge on basal two-thirds, posteriorly with smaller punctures and deeper striz; interstices about the width of punctures, each with a more or less irregular row of distinct punctures, and with many feeble transverse impressions. Metasternuwm with a strong ridge on each side between coxe; punctures of episterna interrupted. Abdomen with first segment feebly depressed in middle, apex widely and feebly produced in middle, where the length is slightly more than that of third and fourth combined, second along middle very little longer than third or fourth, each of these with an irregular double row of punctures across middle. Legs stout; femora rather strongly dentate; hind tibize moderately dilated at apex. Length, 53-6 mm. Q. Differs in having the abdomen with basal segment uniformly convex, its apex not produced, and second segment distinctly longer than third or fourth. Hab.—Queensland: Cairns (HK. Allen). The head and rostrum is much as in crassirostris, but that species has edentate femora. One specimen has a vague white 337 median line on the prothorax, and on the same specimen the scutellum is densely clothed with white scales, but on the others it is more or less glabrous. On many species of the genus the scutellum is rather densely squamose, but as its clothing is particularly lable to abrasion it is usually better left out of consideration. The rostrum of the female is quite as coarsely sculptured as in the male. TYRTZOSUS SIMULATOR, Lea. The locality of the type of this species was somewhat doubtful. There are now, however, two specimens before me, sent by Mr. C. French as from Queensland and another sent by Dr. Turner as from Brisbane. The elytral interstices at first appear to be double, this being due to each having a row of large punctures along its middle. TYRTZOSUS CINERASCENS, Lea. This species was described as having the punctures of the metasternal episterna not quite continuous; on the types, in fact, and on several recently-acquired specimens, just behind the triangular projection on each episternum, there is a short impunctate and usually shining space. But in two specimens from Sydney, and on two from Hobart, this space is supplied with punctures. TYRTHOSUS ICHTHYOSOMUS, Lea. Some specimens from Cape York differ from the types in being smaller (5 mm. only) and with the punctures on each metasternal episternum forming a single row, irregular only on the triangular inner projection. The third and fourth abdominal segments also have each an almost regular single row of punctures across the middle, but on the sides they become irregular. Many specimens have the prothoracic carina quite con- cealed or extremely feeble; on others it is represented by a short, shining, median space. TYRTHOSUS VETUSTUS, Pasc. A common Queensland species, varying in length from 43 to 85 mm. The punctures of the metasternal episterna are usually interrupted, but are sometimes continuous throughout. TYRT#OSUS PARDALIS, Pasce. From Dr. Gestro I received a specimen, evidently a co- type, from Somerset (the original locality) labelled as pardalis and agreeing with the description except in being slightly smaller. In my table of the genus, pardalis is placed with 338 the species whose third and fourth abdominal segments have each two or more rows of punctures (on the co-type these segments have each a single row of punctures across middle) ; and punctures on metasternal episterna not continuous throughout (on the co-type they are continuous). Never- theless the species which I described as pardalis (22) appears to agree with the co-type in all other essential features, and, as noted under some of the preceding species, the interruption, or otherwise, of the punctures on the episterna appears sub- ject to variation, and I previously attached too much import- ance to it. TYRT#OSUS IMITATOR, Lea, var. NORFOLCENSIS, nN. var. A specimen, from Norfolk Island, differs from the type in having the punctures on the elytral interstices considerably smaller, the elytral scales distinctly narrower, the tibiz more dilated at apex, and the femora still more feebly dentate. TYRTZOSELLUS ALTERNATUS, Nn. Sp. Blackish, in parts obscurely diluted with red; antenne, tibiz, and tarsi reddish. Moderately densely clothed with adpressed scales, interspersed with stout suberect ones. Head with dense partially - concealed punctures. Rostrum moderately stout, sides feebly incurved to middle; basal half with coarse more or less concealed punctures, else- where with smaller but clearly-defined ones. Antenne in- serted about two-fifths from apex of rostrum. Prothorazr moderately transverse, sides moderately rounded, apex more than half the width of middle; with dense round punctures; with a feeble median carina. SHlytra oblong-cordate, parallel- sided to beyond the middle; with rows of large partially- concealed punctures, becoming smaller posteriorly; third and fifth interstices hghtly but distinctly elevated, the seventh less noticeably so. Under-surface with fairly dense and large punctures; quite as large on third and fourth segments of abdomen as elsewhere, but much denser and smaller on apical segment. Memora edentate, hind pair extending almost to apex of elytra. Length, 3 mm. Hab.—New South Wales: Tweed River (W. W. Froggatt). Readily distinguished from other species by the elevation of the alternate interstices. On the type (probably a male) the depressed scales are mostly of a dingy greyish-brown or obscure-fawn, but in some lights on the elytra they appear to have a distinct purplish gloss, especially on a large medio- basal space; from other directions, however, this gloss is not (22) Proc: Linn. Soc., N.S.W., 1902, p. 417. 339 evident. The elytra also appear to have a few obscure lines or patches of somewhat sooty scales, but this may be due to partial abrasion. On the prothorax there are three obscure lines of pale scales. The under-surface is sparsely clothed. BoTHYNACRUM OCHREONOTATUM, Nn. Sp. So. Black; antennz and tarsi reddish. Rather sparsely clothed with thin whitish scales. Prothorax with five con- spicuous ochreous spots of scales: a medio-basal one, two medio-lateral ones, and two at apex; elytra with numerous ochreous spots, but mostly on the third, fifth, and seventh interstices. In addition with a conspicuous, postmedian, sutural patch of white scales. Head with moderately dense punctures. Rostrum fully the length of prothorax, with a distinct median carina; with dense punctures more or less concealed behind antennez. Antenne thin, inserted near tip of rostrum. Prothorax lightly transverse, apex about half the width of middle; with a narrow continuous median carina; with large punctures, causing the surface to appear subgranulate. Elytra con- spicuously wider than prothorax, parallel-sided to about the middle; with rows of very large punctures, becoming small posteriorly; interstices obscurely punctate and granulate. Under-surface with rather dense punctures, larger on meta- sternum and two basal segments of abdomen than elsewhere ; apical segment with a large round fovea. Legs long and thin; femora rather lightly dentate; tibie gently curved. Length, 5-6 mm. Q. Differs in being somewhat wider, rostrum thinner, non-carinate; with fairly large partially-concealed punctures only on basal third, elsewhere shining and almost impunctate ; antennz somewhat shorter and inserted less close to apex; and apical segment of abdomen non-foveate. Hab.—New South Wales: Sydney (H. J. Carter); Kiama (E. W. Ferguson) ; Tweed River (H. W. Brown). As the hind femora do not pass the elytra, although they extend almost to the tip, this species would be associated (25) with Tryt@osus; but as in other respects it agrees better with Bothynacrum, and notably in the large abdominal fovea of the male it has been referred to the latter genus. From storeoides it differs in its darker colour, conspicuous ochreous spots, thinner femora with smaller teeth, and punctures of abdomen. To the naked eye the patch of white scales on the suture appears like an irregular V, as on the second interstice it is produced in front of the part on the first; it is margined (23) In a table of the genera applied to Oryptorhynchus in Proc. Linn. Soc., N.S.W., 1907, pp. 401-403. 340 posteriorly with a few ochreous scales. The prothoracic punc- tures are somewhat obscured by scales, but are usually longer than wide, here and there a few of them appear to be longi- tudinally confluent. PEZICHUS PARALLELIROSTRIS, Nl. Sp. Black; antenne and tarsi red. Moderately densely clothed with sooty and ochreous or pale-brown scales; denser and paler on legs than elsewhere; a conspicuous ochreous spot on third interstice at summit of posterior declivity. Head with rather dense punctures, each containing a scale, scales and punctures larger in front than towards base. Rostrum rather long, thin, and parallel-sided; behind antennz with irregular rows of partially-concealed punctures, and with a feeble median carina; in front shining and with small but clearly-defined punctures. Antennz thin, inserted one-fourth from apex of rostrum; scape slightly longer than funicle; club elongate. Prothorax about as long as wide, sides strongly rounded; with dense partially-concealed punc- tures; with a narrow continuous median carina. Scutellum elevated and distinct. Hlytra oblong-cordate, much wider than prothorax; with rows of large, irregularly oblong punc- tures, becoming smaller posteriorly; interstices with a few granules, the third with a conspicuous elongated fascicle near base, and a longer one about middle. Legs long; femora rather strongly dentate, hind pair distinctly passing apex of elytra. Length, 7-74 mm. Hab.—Queensland: Kuranda (H. H. D. Griffith). Rather close to gracilis, but larger and stouter, legs somewhat shorter and stouter, scutellum more distinct and fascicles less so. On the prothorax the carina is traceable throughout and the median fascicle is very feeble (practically absent). On gracilis the carina is very feeble at base and apex, and the median fascicle is conspicuous. The elytral fascicles, which are supported by feeble tubercular swellings, are also composed of shorter scales than on gracilis; their scales are mostly sooty, but the conspicuous ochreous spot on each elytron is part of the larger fascicle. On the basal half of the elytra the interstices are no wider than the punctures, and often distinctly narrower; on the apical half they are usually much wider and each is supplied with a row of stout pale scales. The two typical specimens belong to but one sex; but that sex is doubtful. NEOMYSTOCIS VIRIDIS, Nn. sp. Dull reddish-brown, some parts paler. Densely clothed with moss-green scales; with a few sooty and paler ones. 341 Head with small, dense, concealed punctures. Rostrum moderately long and rather thin, sides lightly incurved to middle; apical two-thirds shining and with minute punctures, elsewhere with larger but more or less concealed ones. Antenne moderately thin; scape inserted in middle of rostrum, slightly shorter than funicle; second joint of funicle slightly longer than first. Prothorax moderately transverse, basal two-thirds with gently rounded sides, apex more than half the width of middle; with four feeble swellings across middle, and a feeble ridge on each side of apex; with a very conspicuous median carina; punctures normally concealed ; with a small nude space near the middle of each side. Scutel- lum distinct. lytra distinctly wider than prothorax, parallel-sided to slightly beyond the middle; with irregular rows of large punctures; third interstice with two large round tubercles: one near base, the other median; fourth with a small tubercle before the middle, and a large one near apex; each shoulder tuberculiform, and a fairly large tubercle be- tween it and the subbasal one on third interstice; elsewhere with a few small swellings. Basal segment of abdomen slightly longer than second, its apex distinctly incurved to middle; second distinctly longer than third and fourth combined. Legs rather long; femora acutely dentate; tibis compressed. Length, 12 mm. Hab.—New South Wales: Tweed River (H. W. Brown). With the conspicuously green scales of fresh specimens of squamiventris, but with shorter legs, larger elytral tubercles, more conspicuous prothoracic carina, and abdominal segments different. The outlines of its upper-surface are suggestive of affinity with Zsazx gallinago, and Pseudometyrus antares, of the Chetectetorus group. On the elytra there are some pale elongate scales scattered about, and they con- spicuously crown the small median tubercle on the fourth interstice. The large tubercles on the third, and the median ones on the prothorax, are crowned with sooty scales. The type, whose sex is doubtful, is evidently in perfect condition, but probably (as with other normally green species of the sub- family) specimens that have been in alcohol or are old and greasy will have the scales more or less greyish. The three large tubercles on each elytron are almost in a line. Genus Hyparinus, Pascoe. (24) There is before me a specimen, taken by d’Albertis in New Guinea and sent by Dr. Gestro as Hyparinus dispar, and I believe correctly so. The specimen measures 10 mm., and (24) Ann. Mus. Civ. Gen., 1885, p. 275. 342 so, according to the description, is presumably a female. There are several species of the same genus in Australia, and some additional particulars to those contained in the original generic and specific diagnoses may be acceptable. Pascoe described the three intermediate segments of abdomen as equal, but the second is just a trifle longer than third or fourth, and in several other (Australian) species is distinctly longer. He described the prothorax as longitudinally sulcate, but this is scarcely correct; the prothorax is flattened and sparsely squamose along middle, and in the exact middle the derm is glabrous, but there is no actual groove or sulcus. The head is conspicuously quadri-impressed in front, with con- spicuous coste separating the impressions. The elytra have a row of small shining granules on each side of the suture; they have fairly large punctures, subseriately arranged, but not in strie. The basal segment of abdomen has a con- spicuous notch in the middle of its apex. The hind femora, when placed in the same line as the abdomen, have their teeth level with the tip of the elytra, so that their apices considerably pass it.(5) The genus is allied to Pezichus and Neomystocis, from the former distinguished by the finely- faceted eyes, and from the latter by the cavernous meso- sternal receptacle. All the species are winged. HYPARINUS DISPAR, Pasc. (26) A specimen from Kuranda (from Mr. Griffith, who has another from the Mulgrave River) agrees perfectly with the above noted specimen. It is now first recorded as Australian. HYPARINUS TENUIROSTRIS, Nn. Sp. ¢. Black; antenne and tarsi red. Rather densely clothed with muddy-brown or sooty scales; with longer scales rather thickly scattered about, especially on the legs. Pro- thorax with several feeble fascicles; elytra with fascicles on tubercles. Head with forehead strongly quadrisinuate. Kyes very large. Rostrum very long and thin; basal fifth with coarse partially-concealed punctures, then with small but distinct ones to insertion of antenne, in front of same shining and with sparse and minute punctures. Antenne thin; scape inserted two-fifths from base of rostrum, almost the length of four following joints combined; funicle with second joint almost twice the length of first, the others regularly decreas- ing in length, but none transverse. Prothorar rather lightly (25) In the figure the femora are drawn as if they would not, or scarcely, pass the tip. (26) Ann. Mus. Civ. Gen., 1885, p. 276, pl. 11., fig. 3. 343 transverse, sides strongly rounded, apex about half the width of base; with very dense normally-concealed punctures. Elytra subcordate, base strongly trisinuate, shoulders thickened; with rows of large partially-concealed punctures ; with a few sutural granules; each with five distinct tubercles and some smaller ones. Basal segment of abdomen as long as second and third combined, its apex evenly incurved to middle; second almost as long as third and fourth combined. Legs long; femora stout, strongly and acutely dentate, hind ones passing apex of elytra for a considerable distance; tibize very thin, the hind ones shallowly emarginate near apex, the apex itself with two golden fascicles, the apical hook long, strongly curved and with its apex again curved. Length, 10-11 mm. Q. Differs in having the antenne inserted rather nearer base of rostrum, the rostrum itself more sparsely clothed about base, basal segment of abdomen gently convex, and legs some- what shorter, with stouter tibiz, the hind pair of which have apical spur as on the others and with one fascicle only. Hab.—New South Wales: Dorrigo (H. J. Carter and E. W. Ferguson). In general appearance remarkably close to dispar, but with second segment of abdomen distinctly longer than third and its suture with the first curved in middle instead of straight. The elytral tubercles are placed as on brevipes. On the type male the prosternum has numerous whitish scales margining the pectoral canal; its hind tibie are also curiously armed. 7 DYSOPIRHINUS QUADRINOTATUS, Nn. sp. Black; antenne and claw joint of a dingy-red. Moderately clothed with ochreous or brownish scales, in places becoming sooty. Elytra with four conspicuous pale spots: two before and two beyond the middle; a conspicuous triangle of pale scales on each side of mesosternum. Head with a feeble median ridge; with a narrow im- pression behind each eye. Rostrum about as long as pro- thorax, evenly curved, sides incurved to middle, but feebly dilated at antennz; on basal third punctures concealed, but elsewhere clearly defined and rather dense. Scape inserted about one-third from apex of rostrum; second joint of funicle longer than first. Prothorax subconical, about as long as wide; with numerous large, round, depressed granules or small tubercles, absent from a fairly large medio-apical space ; with a conspicuous median carina. Elytra_ elongate- subcordate, each separately rounded at base, not much but distinctly wider than prothorax, sides decreasing in width 344 from shoulders to apex; with rows of large deep punctures; interstices evenly rounded on sides, but not about suture; suture with some small granules. Under-surface with sparse punctures. Legs rather long and thin; femora lightly dentate, hind pair scarcely extending to tip of elytra. Length, 17-18 mm. Hab.—Queensland: Kuranda (H. W. Brown). Readily distinguished from grandis by the spots on elytra and metasternum. From the New Guinea albosparsus it differs in being more densely clothed, elytra more narrowed pos- teriorly, and with only four spots; these are on the fourth interstices, but also partly on the third, and are at almost equal distances, both longitudinally and transversely. The hind femora when placed in a line with the elytra appear to just extend to the tip of same. In grandis in the males they distinctly pass the apex, in the females they usually just pass it, but im some small ones they terminate before the apex. The types (two) are evidently of but one sex, probably female. PROTOPALUS SCHONHERRI, Waterh. Mr. H. W. Brown has taken two pairs of this species in the Cairns district, with the shoulders of both sexes much more prominent than in the typical form (quite as prominent as in dromedarius). The elytra are also rather more robust. PALETONIDISTUS TRISINUATUS, Lea. The forehead of the type of this species was, quite cor- rectly, described as trisinuate; but six specimens, from Dor- rigo, recently sent for examination by Dr. Ferguson, all have the forehead distinctly quadrisinuate. On the type the head has a median carina that does not extend to the forehead, con- sequently the median sinus is not interrupted; but on the Dorrigo specimens the carina is continuous to the forehead, thus splitting up the median sinus into two. The tibie are strongly bisinuate on their lower-surface, this being due to an almost angular projection at the middle of each. On speci- mens in good condition the disc of the prothorax appears to be impunctate, but after the scales have been abraded punc- tures. become visible. The mesosternal receptacle was incor- rectly described as longer than wide, as it is really moderately transverse, although, at a glance, it appears to be slightly longer than wide; its median ridge is scarcely traceable on specimens in good condition. The female differs from the male in being somewhat wider, with less.of the rostrum coarsely sculptured, and the sinuation of the tibize more pronounced. 345 HEXYMUS ALATUS, n. sp. ¢. Black; antenne and tarsi of a rather bright-red. Closely covered with small dingy-brown scales ; with numerous stout suberect scales, mostly ochreous or pale-brown, but some- times sooty, interspersed. Head with very dense concealed punctures. Rostrum long and rather thin, slightly decreasing in width from base to antenne, and then parallel-sided to apex; on basal two-fifths with coarse concealed punctures and a narrow median ridge, elsewhere shining and with small punctures. Antennz thin, inserted about two-fifths from apex of rostrum; second joint of funicle almost twice the length of first. Prothorax rather widely transverse, basal two-thirds almost parallel-sided, apex about half the width of base; with a distinct but obtuse median ridge. Seutellum fairly large. Hlytra oblong-cordate, distinctly wider than prothorax, base strongly trisinuate, sides gently rounded; with rows of rather large, angular, partially- concealed punctures; third interstice with a feeble elevation at basal third and a more distinct one at middle, fifth with a small one at basal third. Il’ings present. Under-surface with dense and mostly-concealed punctures, a few of large size at base of metasternum and of abdomen. Metasternum not much shorter than the following segment. Legs long; femora stout, strongly and acutely dentate, hind ones passing tip of elytra; tibie thin, somewhat curved at base. Length, 71-8 mm. Q. Differs in having the rostrum somewhat thinner, punctures concealed only about basal fourth, antenne inserted in middle of rostrum, emargination of mesosternal receptacle longer, and abdomen more convex. Hab.—Queensland: Cairns (E. Allen and E. W. Fer- guson). This species should, I think, be treated as an aberrant Hexymus, the winged body and consequently longer metaster- num are certainly at variance with all the other species of the genus, but it agrees with all the other characters noted in the revision of the genus.'2”) The stout scales are irregularly dis- tributed, and are more numerous on the elevated parts than elsewhere, but they do not form fascicles, except perhaps on the third interstice. Qn one specimen there are several small sooty spots on the elytra, but on the others the sooty scales are usually scattered singly. On abrasion the prothorax is seen to be densely covered with small punctures, and with sparser and moderately large deeply-impressed ones ; the latter appear as small ones through the clothing, but the former are normally concealed. (27) Proc. Linn. Soc., N.S.W., 1898, p. 203. 346 NOTOCALVICEPS PUNCTIPENNIS, Lea. A specimen from Cairns differs from the description of the type of this species in being slightly larger (10 mm.), and with two small whitish spots slightly before the middle of the elytra (as in rarus) instead of near the apex (as on the type). In the generic description the eyes were noted as finely faceted ; this is incorrect. The facets are of moderate size or rather coarse. DIAPHOROCIS, n. g. flead rather small but distinct from above; forehead quadrisinuate. Hyes rather small, coarsely faceted, widely separated. Rostrum long, thin, and curved. Antenne rather thin; scape inserted much closer to base than to apex of rostrum, not half the length of funicle ; funicle with two basal joints elongate, none of the others transverse ; club subovate. Prothorax transverse, sides rounded, base truncate. Scutel/um absent. H#lytra not much wider than prothorax, subparallel- sided to near apex. Pectoral canal deep and narrow, termin- ated between middle coxe. #Mesosternal receptacle scarcely raised, rather widely U-shaped, base slightly stouter than sides, emargination feebly transverse; cavernous. Meta- sternum along middle about half the length of the following segment; episterna very narrow. Abdomen rather large, sutures straight and distinct, first segment almost as long as three following combined, second almost as long as two follow- ing combined. Legs not very long; femora stout, acutely dentate ; tibia compressed ; tarsi rather long and thin. Some- what depressed, squamose, fasciculate, coarsely punctate. In many respects close to Methidrysis (the forehead, rostrum, and antenne are practically identical), but without a scutellum and very differently sculptured. NVotocalviceps, to which, perhaps, it is closer, has also a scutellum and has meta- sternal episterna distinct throughout. In an (at present M.S.) table of the genera allied to Poropterus, it would be associated with Terporopus, which has larger eyes, insertion of scape more distant from the base, elytra narrower and deeper, abdo- men considerably narrower, and femora thinner, with the hind pair passing apex of elytra. In general appearance the species described below resembles some species of Omydaus and of Poropterus, but from the former the quadrisinuate forehead is at once distinctive, and from the latter the strongly dentate femora. DIAPHOROCIS VARIEGATUS, N. sp. Black; antennez and tarsi of a rather bright-red. Some- what irregularly clothed with scales, varying from snowy- white, through ochreous, to black; and from small and closely applied to the derm to stout and suberect. 347 Head with forehead conspicuously quadrisinuate, in front of same punctures concealed; ocular fovea narrow. Rostrum strongly curved, each side behind antennz dilated towards but notched at base; behind antenne with coarse concealed punc- tures, separated by narrow, distinct ridges; in front of same highly polished and sparsely and minutely punctured. Pro- thorax not much wider than long, apex more than half the width of middle; with rather coarse irregular punctures ; with an irregular median carina, somewhat dilated in middle. Elytra at base not much wider than widest part of prothorax, but distinctly wider than its base, base strongly trisinuate ; with rows of large round punctures, becoming smaller pos- teriorly : interstices decidedly narrower than punctures. Two basal segments of abdomen with large sparse punctures, apical segment with smaller and denser ones. Length, 5-6 mm. Hab.—Queensland: Toowoomba (Horace W. Brown) ; Rockhampton (H. W. Cox). On the prothorax most of the scales are stout, more or less brownish or ochreous, and in places compacted into feeble fascicles, but there are usually a few snowy scales on the disc and sides. On each elytron there is a very conspicuous snowy transverse spot, irregularly extending from the third interstice to the fifth, slightly before the middle, there is also a distinct ochreous fascicle on the third near base; elsewhere there are numerous feeble ochreous or sooty fascicles. On the under- surface the scales are very irregularly distributed, much of the surface being naked. The legs are usually conspicuously ringed. POROPTERUS. This genus is abundantly represented in Australia, and contains forms that at first appear to belong to several distinct genera. In formerly?) dealing with the genus i considered that all species having the femora either dentate or grooved should be excluded from it. But several species were then allowed to remain in the genus, or were referred to it, whose femora are really dentate, although the teeth, being very small and usually concealed by the clothing (and frequently also by dried mud), they were overlooked till quite recently. The species referred to belong to the eritvosus group, and appear to form a natural cluster characterized by the wide flat pro- thorax, multi-tuberculate elytra with projecting shoulders, absence of scutellum, and by the deep abdominal sutures. The described species of the group are : — P. exitiosus, Pasc. ‘This is the typical species of the group; its femora at first appear to be edentate, but on close (28) Proc. Linn. Soc., N.S.W., 1897, p. 455. 348 examination a small tooth on each may be seen, the tooth being | the median culmination of a short narrow ridge. In the original description the femora are not mentioned, and the species was stated to have a scutellum. Probably Mr. Pascoe was deceived by some clothing or dirt in the scutellar region. P. python, Pasc. (l:istroderes, Lea). On the type of listroderes all the femora have a short ridge that would pro- bably be overlooked unless specially looked for, but the ridges do not culminate in teeth. P. bisignatus, Pasc. ‘ I have been unable to find ridges or teeth on any specimen of this species, although it is evidently allied to exitrosus. P. fovecpennis, Pasc. In this species the femora are not dentate, but they are very conspicuously grooved. I had pur- posed proposing a new genus for it on this account, but as in most of its characters 1t appears to be a member of the exitiosus group, have refrained from doing so. P. variabilis, Lea. The femora are much as on ezifiosus, but the’ teeth and ridges are still more feeble, and on the front pair are sometimes altogether wanting. P. humeralis, Lea. Extremely feeble ridges and feeble teeth are traceable on the four hind femora of this species, but on the front pair the teeth appear to be absent, although a slight swelling on each may be noticed at the position of the tooth. Two new species of the group may also be noted. P. platyderes, n. sp. The four hind femora each have a subtriangular ridge on tooth that is very distinct from some directions, and only partially concealed by the clothing from the sides; but on the front pair the teeth are less evident. At a glance the species appears to belong to python. P. latipennis, n. sp. Feeble ridges are traceable on the femora, but nowhere become angular or dentate. POROPTERUS POSTICALIS, nN. sp Black; antenne and tarsi more or less red.(29) Rather sparsely (more densely on tubercles and legs than elsewhere) clothed with muddy-brown and ashen scales. Head with sparse shallow punctures, except at extreme base, where they are smaller and rather dense. Eyes rather coarsely faceted. Rostrum moderately long, parallel-sided, and with irregular rows of coarse punctures behind antenne; in front of same somewhat wider, and with denser and smaller punctures. Antenne inserted one-third from apex of (29) The colours of the derm and appendages are practically identical in this and all the following species. 349 rostrum; first joint of funicle slightly stouter and slightly shorter than second. Prothorax slightly longer than wide, sides strongly rounded; apex produced and concave, with a ridge bounding the concave portion; subapical constriction deep, irregular, and suddenly terminated at ridge; with four rather feeble tubercles placed transversely at middle; with large, round, irregularly - distributed punctures; median carina absent except at extreme base, where it appears as a scutellar lobe. Scutellum indistinct or absent. JHlytra narrow, much deeper than wide, scarcely wider than pro- thorax; sides with large deep punctures on fovez, in places connected so as to appear like zig-zag grooves; along middle and on posterior declivity with much smaller punctures; pos- terior declivity somewhat flattened, almost half the total length of elytra, each side of its summit crowned with a large round tubercle; third interstice at about basal fifth with a rather small round tubercle, a still smaller one close behind it, elsewhere with feeble tubercular swellings; suture and tubercles with small, shining, squamiferous granules. d/eso- sternal receptacle rather large at the base, walls of emargina- tion thin and widely U-shaped. Legs long and thin; third tarsal joint rather wide and deeply bilobed. Length, 6 mm. Hab.—New South Wales: Sydney (A. M. Lea). The type is probably a male, and is minus its abdomen and hind legs, but it is so distinct that it has been described. It is a narrow deep species, allied to parvidens and ornati- collis, from both of which it may be distinguished by the large tubercles overhanging the posterior declivity, the declivity itself being unusually long and abrupt; not rounded as in those species. Seen from the sides the elytra appear to have a posterior slope for about half their total length, then an undulated median space, and then a shorter and somewhat concave basal slope. The eyes are quite as coarsely faceted as in ornaticollis. As the middle femora extend to the apex of elytra, the hind pair are certain to pass the same. POROPTERUS STENOGASTER, Nl. sp. Densely clothed with more or less muddy-brown, setose scales or sete, becoming fasciculate on tubercles; rostrum in front of antenne, and parts of under-surface, glabrous. Head with coarse but partially-concealed sculpture. Eyes coarsely faceted. Rostrum moderately long, somewhat suddenly inflated in front of antenne; with dense punctures, clearly defined on apical third, larger but partially concealed elsewhere. Antennz inserted one-third from apex of rostrum, first joint of funicle stouter and slightly longer than second. Prothorax slightly longer than wide, sides rounded in middle, 350 apex lightly produced; subapical constriction irregular and terminated before summit; with four fasciculate tubercles across middle; carina partially concealed, but appearing at base as a scutellar lobe; with large, round, irregularly distributed, and often concealed, punctures. Hlytra narrow and deep, nowhere wider than widest part of prothorax; sides with large deep punctures or foveze, frequently more or less irregularly conjoined, elsewhere with large punctures but much smaller than on sides; third interstice with an elongate tubercle at basal fifth, a smaller one at basal two-fifths, a large one (somewhat curved outwards) crowning the posterior declivity, an elongated one at apex, and a small one near apex; fifth interstice with two small tubercles; suture tuber- culate halfway down posterior declivity, and on basal half with small shining granules. Mesosternal receptacle with basal portion rather large; emargination semicircular. Abdomen long and parallel-sided almost to apex, first and fifth segments each as long as three median ones combined ; second as long as third and fourth combined, with a strong median ridge or elongated tubercle; apical segment convex along middle, with dense clearly-defined punctures. Legs long and thin; front femora feebly, the others rather strongly, grooved, hind pair terminated considerably before apex of abdomen; third tarsal joint moderately wide and deeply bilobed. Length, 6 mm. Hab.—Australia (A. Bovie). A narrow deep species, with coarsely faceted eyes and curious abdomen. It is allied to parvidens, ornaticollis, and posticalis, from all of which it may be distinguished by the sutural tubercle, shorter femora, and long abdomen. The femora appear to be all feebly grooved, but when viewed from certain directions the grooves on the four hind ones are very distinct. The forehead appears to be trisinuate, with a wide sinuous impression before it, but the sculpture is more or less concealed by the clothing. The type is probably a male. POROPTERUS MAGNUS, Nl. Sp. 3. Moderately densely clothed with ochreous or reddish-brown scales, becoming dense fascicles on tubercles; legs densely clothed. Head without normally visible punctures. Ocular fovea large. Rostrum moderately long and rather stout, sides feebly inflated between base and antennz, and then dilated to apex; with numerous punctures but more or less concealed behind antenne. Antenne inserted one-third from apex of rostrum; two basal joints of funicle subequal in length. Prothorax about as long as wide, apex bituberculate; with 351 four tubercles across middle, the median ones much larger than the outer ones, and semi-double; subapical constriction deep and irregular, at median carina suddenly deflected back- wards to tubercle; elsewhere with deep and more or less curved grooyes; median carina very distinct, somewhat de- pressed at apical third. Scwtellwm absent. Elytra elongate- ovate; with rows of large deep punctures, larger on sides than elsewhere; second interstice with an elongated fascicular crest, near base, about middle, and at summit of posterior declivity supported by distinct tubercles; fourth interstice with two moderately large and two small fasciculate tubercles, a few feeble ones elsewhere. J/esosternal receptacle fairly large and strongly raised; emargination widely transverse. Abdomen with dense more or less concealed punctures; first segment not as long as three following combined and scarcely longer than fifth; second, third, and fourth of almost even lengths, their sutures deep. Legs long and thin; hind femora just passing apex of elytra; third tarsal joint slightly nar- rower than second and not deeply bilobed. Length, 153-20 mm. @. Differs in being somewhat stouter, in having the rostrum considerably longer and somewhat thinner, with its sides not inflated near base, antennz inserted less close to apex of rostrum, and legs a trifle shorter. Hab.—Queensland: Cairns district (Macleay Museum, EH. Allen, F. P. Dodd, and H. Hacker). 0 A large species, close to carinicollis but with median pro- thoracic carina not overhanging the scutellar region, the tarsi with denser clothing and truly lnear SY) and without a conspicuous lateral tubercle near shoulder when viewed from above. Rubus has more numerous tubercles, is without elongated fascicles on the posterior declivity, and has small conical apical tubercles. Jntermedius and idolus have con- joined tubercles at summit of posterior declivity, different tarsi, etc. The scales composing the fascicles are usually, but not always, darker than the adjacent ones. As with many others of the genus, the whole of the derm, on the spaces between the scales, is closely covered with minute black scales (invisible except on a close examination), giving the surface a somewhat shagreened appearance. One large specimen differs from the others in having the individual scales much shorter, so that the tubercles and (30) Specimens are in the Australian Museum (K. 12581 of that aa and in Mr. C. French's collection from the Endeavour iver. (31) 14 would thus be a Mormosintes, if the linear tarsi were to be regarded as of generic importance. 352 ridges appear distinctly as such, rather than as supports for fascicles, and the punctures and grooves are much more con- spicuous, although really not larger. The prothoracic carina is not transversely impressed at the apical third, and the minute dermal scales are also greyish, so that the derm be- tween the larger scales does not appear to be everywhere jet-black. POROPTERUS BASIPENNIS, Nl. sp. Densely clothed with small ashen - grey (almost stramineous) scales, closely applied to derm; with numerous stout, but similarly coloured, scales, scattered about and be- coming fascicles on tubercles, but the fascicles usually with a dark centre; legs, head, and rostrum (almost to tip) densely squamose. Head somewhat depressed, punctures normally concealed. Rostrum rather long, parallel-sided from base to antenne, and then slightly dilated to apex; punctures normally con- cealed except at apex. Antennz inserted one-third from apex ‘of rostrum; second joint of funicle almost twice the length of first. Prothorax longer than wide, sides rounded in middle, apex produced and bifasciculate; with two feeble median tubercles supporting distinct fascicles; subapical constriction deep on sides, but shallow across middle; sides near base, deeply grooved. Scutellum absent. SHlytra long, narrow, and deep; sides widest just beyond the middle, and strongly arcuate near apex; with rows of large round punctures, larger and more distinct on the sides than elsewhere ; shoulders produced; third interstice conspicuously produced at base, fasciculate at basal fourth, and about the middle; fifth inter- stice with a feeble fascicle about the middle. and another posteriorly; suture conspicuously fasciculate halfway down the posterior declivity, and apex bifasciculate. Mesosternal receptacle raised, basal portion large, emargination semi- circular. Abdomen with numerous punctures; basal segment as long as three following combined, intercoxal process con- spicuously triangular, suture incurved to middle of apex, second decidedly longer than third and fourth combined, and much longer than fifth. Zegs long and thin; hind femora not extending to apex of abdomen; third tarsal joint moderately wide and deeply bilobed. Length, 11 mm. Hab.—Queensland: Mount Bellenden-Ker (A. Solari from — Podenzana). A narrow species with peculiar clothing and otherwise very distinct from all previously described species. The fascicle on the suture is at the same position as on stenogaster, but the two species have little else in common. The clothing is so dense that no prothoracic punctures are visible, nor is a 353 median carina traceable. On the type, which is almost cer- tainly a male, two of the prothoracic, and five of the elytral, fascicles are conspicuously dark in the middle. In favourable lights the derm appears to be covered with similar minute black scales to those of the preceding species. POROPTERUS PLATYDERES, Nn. sp. 3. Densely, but in places sparsely, clothed with stout ochreous or light-brown scales, usually closely applied to derm, becoming fasciculate, and usually darker on tubercles; legs, head, and rostrum to antenne densely clothed. Head somewhat depressed. Rostrum rather short and stout, very feebly curved, parallel-sided to between antenne, and slightly dilated in front of same; with numerous small but clearly-defined punctures in front, elsewhere larger but more or less concealed. Antenne rather thin, inserted one- fourth from apex of rostrum; second joint of funicle twice the length of first. Prothorax wide and almost flat, basal half almost parallel-sided, thence strongly narrowed to apex, which is conspicuously produced and bifasciculate; median carina absent ; subapical constriction feeble. Scutellwm absent. Elytra wide, closely applied to prothorax; with rows of large punctures, more regular but not larger on sides than along middle; base with six tubercles, of which the largest are humeral, third interstice with three fairly large tubercles, one just before and one just after middle, the other just below summit of posterior declivity, fourth interstice with a sub- basal tubercle, at first appearing to be on the third, seventh interstice almost ridged from beyond the middle to near apex ; apex obtusely bituberculate, several feeble tubercles elsewhere ; about suture with some shining granules. MMJesosternal recep- tacle large, emargination strongly transverse. Abdomen with numerous more or less concealed punctures; basal segment as long as three following combined; a deep curved groove near base ; second segment slightly shorter than fifth, and distinctly shorter than third and fourth combined; sutures deep and straight. Legs moderately long; femora rather stout, each with a feeble subapical ridge, culminating in a small but dis- tinct tooth, posterior almost extending to apex of elytra; third tarsal joint wide and deeply bilobed. Length, 9-11 mm. Q. Differs in having the rostrum longer, thinner, more noticeably dilated to apex, clothed only about extreme base and with smaller but more clearly-defined punctures ; antennze inserted not quite so close to apex of rostrum, and legs slightly shorter. Hab.—New South Wales: Blue Mountains (HE. W. Fer- guson). M 354 A wide flat species, in general appearance strikingly like python, but apex of elytra tuberculate, tubercles on posterior declivity nearer the summit, each shoulder with the outer tubercle the larger instead of the smaller, and the femora somewhat different. The scales very densely clothe the sides of the prothorax ; on the elytra a pale irregular stripe of scales appears to extend from the shoulder to the apex, with an inner dilation near the middle, but this appearance is mainly due to. the comparative sparseness of scales along the middle. POROPTERUS LATIPENNIS, N. Sp. More or less densely (in places almost glabrous) clothed with scales varying from ashen-grey to sooty, but mostly of a rather light-brown; tubercles usually with dark fascicles ; legs densely clothed and feebly ringed. Head wide; punctures normally concealed. Ocular fovea. shallow. Rostrum short, stout, and feebly curved, dilated in front of antennz ; apex with dense and clearly-defined punc- tures. Antenne rather stout, inserted about one-third from apex of rostrum ; second joint of funicle distinctly longer than first. Prothorax wide and lightly convex, sides strongly rounded, apically strongly narrowed and produced, apex bifas- ciculate ; median carina absent; subapical constriction feeble. Scutellum absent. Hlytra wide, subcordate; shoulders pro- duced and tuberculiform ; with rows of large, deep punctures, becoming smaller posteriorly ; each elytron with two fascicles. at summit of posterior declivity, one on the second, the other on the third interstice; third with two other fasciculated tubercles, one about middle, the other at basal fourth; fifth interstice with two feeble fascicles; apex feebly bifasciculate, several feeble fascicles elsewhere. dJfesosternal receptacle large, medio-basal portion triangular owing to a large exca- vation on each side, apical portion wide ; emargination shallow. Abdomen with deep sutures; first segment almost as long as three following combined, its apex incurved to middle, near base with a strong curved groove; second shorter than third and fourth combined. Legs rather short; femora stout, hind pair extending to tip of elytra; third tarsal joint not very wide. Length, 9 mm. Hab.—Queensland: Little Mulgrave River (H. Hacker). At a glance apparently close to the following species, but really belonging to the ezitiosws group. The rostrum of the type is clothed along the sides to the antenne, but not along the middle, but this may be due to abrasion. Owing to the shape of the receptacle the pectoral canal appears to terminate between the front legs. From some directions the forehead appears to be trisinuate, but only the median sinus is at all distinct. 355 PoROPTERUS TRIFOVEIVENTRIS, Nn. Sp. Clothed with sooty-brown scales, dense and fasciculate on tubercles, and usually sparse elsewhere; with a short oblique stripe of pale scales, from the third to the seventh interstices, at the apical third of elytra; legs densely clothed with sooty- brown scales, with feeble paler rings; head and rostrum to antenne densely clothed. Head \arge; forehead lightly sinuate ; punctures normally concealed. Rostrum rather short, stout, and lightly curved; sides distinctly inflated between base and antenne, and again dilated to apex. Antennz rather stout, inserted one-third from apex of rostrum; second joint of funicle distinctly longer than first. Prothorazr about as long as wide, somewhat flat- tened, sides strongly rounded; across middle with a double series of four very feeble tubercles, supporting fascicles, the median ones of these continued as feeble crests to apex; with rather large, irregularly-distributed punctures ; subapical con- striction deep and irregular on sides, but not continued across summit. Scutellwm absent. SHlytra elongate-ovate; with large punctures becoming smaller posteriorly; second inter- stice with an interrupted fascicular crest, commencing at sum- mit of posterior declivity, and continued to apex; third with an elongated fascicle near base, another about middle, and a whitish one at summit of posterior declivity; fifth with a fascicle near base; shoulders tuberculate, elsewhere with feeble fascicles. Mesosternal receptacle as in preceding species. Abdomen with first segment almost as long as three following combined, near base with two large partially-conjoined fovee, at apex with another fovea common to it and the second seg- ment, suture between these segments deep at the sides, but interrupted on each side of the fovea; second almost as long as third and fourth combined. Legs rather short and stout ; hind femora not extending to apex of abdomen; tarsi rather narrow. Length, 84 mm. Hab.—Queensland: Cairns (H. Hacker). An aberrant member of the /ithodermus group. The apical fovea of the first abdominal segment, although common to the two basal segments, is round instead of sulcate, as in rubeter and sulciventris; the two subbasal fovee might be regarded as an interrupted groove. In addition to the pale scales, already noted on the elytra, there are a few clusters of similar scales scattered about; there are also some reddish- ochreous ones at the sides, where the prothorax and elytra touch. The punctures along the suture are unusually large and distant, so that, counting from the base, the fifth is at the summit of the posterior declivity. The femora each have a short submedian ridge, but the ridges are not angular or M2 356 dentate; to a certain extent they cause the femora to appear to be feebly grooved. The third tarsal joint is longer than wide, and less deeply bilobed than usual; but, as it is slightly wider than the second, the tarsi cannot be regarded as linear. The type appears to be a male. POROPTERUS CRASSIPES, Nn. sp. Densely clothed (but in places almost or quite glabrous) with sooty scales, variegated with more or less concealed whitish ones. Head with coarse but more or less concealed punctures. Eyes small and coarsely faceted. Rostrum stout and rather short, sides incurved to middle; with rows of large irregular punctures, becoming much smaller, denser, and not seriate in arrangement in front. Antenne inserted about two-fifths from apex of rostrum; scape unusually short and stout; first joint of funicle stouter and a trifle longer than second. Prothorax almost as long as wide, lightly convex, sides strongly rounded and strongly narrowed to apex, which is produced ; with a very obtuse median carina; with four feeble longitudinal fascicu- late crests ; with numerous large punctures. Scutellwm absent. Elytra rather long, base scarcely wider than base of prothorax, then gently rounded and near apex arcuate; with rows of large punctures, becoming smaller (but still large) posteriorly ; third and fifth interstices fasciculate near base, and at summit of posterior declivity, many small fascicles elsewhere. /eso- sternal receptacle much as in two preceding species. Abdomen with deep sutures ; first segment almost as long as three follow- ing combined, near base with a strong curved impression and deeply impressed in middle of apex; second about as long as third and fourth combined, with two notches just behind apical fovea of the first; two basal segments with large punctures, the others with dense and much smaller ones. Jegqs. short ; femora unusually stout, conspicuously grooved, hind pair scarcely extending to apical segment; tarsi with third joint not much wider than second. Length, 5 mm. Hab.—Victorian Alps (H. J. Carter). Close to sulciventris, but smaller and narrower, with some- what different clothing and elytral punctures considerably smaller and less angular, etc. The grooving of the femora is an aberrant feature in the genus, but they are also grooved in sulciventris, and the two species have the deep abdominal sulcus of ruwbeter (a member of the ezitiosus group). There is a conspicuous but irregular line of whitish scales crowning the posterior declivity, a few at the extreme base of elytra, two or three together on each side of the middle of the prothorax, similar spots close to each eye, and conspicuously variegating the legs. 357 PoROPTERUS MULTICOLOR, Ni. sp. Densely clothed with scales, mostly reddish-ochreous, but varying (usually in small patches) to stramineous and sooty; apical two-thirds of rostrum glabrous. | Head with punctures more or less concealed. Rostrum rather long and thin, sides distinctly inflated near base, then incurved to antennz and then feebly dilated to apex; with numerous rather small but clearly-defined punctures on apical half, more or less concealed elsewhere. Antenne inserted slightly nearer apex than base of rostrum; first joint of funicle stouter and slightly longer than second. Prothoraz about as long as wide, sides strongly rounded; subapical con- striction shallow; with dense large punctures. Scutellum absent. Hlytra elongate, base slightly less than widest part of prothorax, sides very feebly rounded; with regular rows of large and somewhat distant punctures, larger and closer together on sides than elsewhere; with many small depressed black fascicles, more numerous on the third and fifth inter- stices than elsewhere, but absent from suture. Mesosternal receptacle scarcely raised, base fairly large, emargination semi-circular. Abdomen densely punctate, with deep sutures ; basal segment slightly longer than three following combined, second as long as third and fourth combined. Legs rather short; femora moderately grooved, the hind pair just passing tip of elytra; front tibiz distinctly bent inwards; third tarsal joint rather wide and deeply bilobed. Length, 7-74 mm. Hab.—New South Wales: Blue Mountains and Ourim- bah (E. W. Ferguson). (2) A member of the difficult lithodermus group, but with femora rather distinctly grooved. The clothing in some respects is like that of wndulatus, but the elytra are differently sculptured, the fascicles are fewer in number and differently disposed, prothoracic carina less conspicuous and tibie dif- ferent; cavernosus is smaller, with different outlines, pro- thorax with denser clothing, etc.; bituberculatus and lis- sorhinus have shining tubercles at base of elytra. The absence of fascicles or dense clothing from the suture on the posterior declivity readily distinguishes it from other members of the group. On the prothorax a median carina appears to be traceable from base to apex, but it is entirely covered by scales. The punctures are also more or less obscured by scales. On the upper-surface the dark scales are mostly condensed into fascicles. In certain lights many of the scales appear almost scarlet. The thin sete at tips of tibis are more or less golden. (52) IT have also seen a specimen, in Mr. Cox’s collection, from Illawarra. 358 POROPTERUS MOLLIS, Nn. sp. Very densely clothed with large soft scales, varying from ashen-grey to sooty, the latter mostly composing fascicles ; apical fourth of rostrum glabrous. Head with normally-concealed punctures. Rostrum moderately long, sides incurved to middle; with dense and coarse punctures, concealed except near apex. Antennz in- serted about one-third from apex of rostrum; first joint of funicle much longer than second. /Prothoraz slightly longer than wide, sides strongly rounded, subapical constriction shallow but continuous; apex with two fascicles, across middle four more, but the median ones semi-double; with dense normally-concealed punctures; with a feeble median remnant of a median carina. Scutellum small. JHlytra elongate or elliptic-ovate; with many fascicles, mostly blackish, more numerous on third and fifth interstices than elsewhere, some- times appearing as more or less elongated crests, a distinct fascicle on suture beyond the middle; with large punctures more or less concealed, even on sides. Mesosternal receptacle feebly raised; emargination strongly transverse. Abdomen with numerous but more or less concealed punctures; first segment slightly longer than three following combined, its apex lightly incurved to middle; third and fourth strongly depressed below level of second and fifth, their combined length distinctly shorter than that of either of those segments. Legs rather short; hind femora not extending to apical seg- ment; third tarsal joint rather wide and deeply bilobed. Length, 9 mm. Hab.—Tasmania: Hobart (A. M. Lea). A narrow densely-squamose species of the antiquus group. In some respects it is close to alboscutellaris, but is narrower and with a fascicle on the suture just before hind declivity; the latter character readily distinguishes it from all other members of the group. Many members of the lithodermus group have such a fascicle, but those species are all exscutel- late. The type is probably a male. POROPTERUS SIMSONI, new name. I have to propose this name for the species I described as P. nodosus, Dr. Ferguson having kindly drawn my atten- tion to the fact that that name had been previously used for a New Guinea species of the genus, originally referred to Mormosintes. 9) The type of the species is a male. The female differs in having less of the rostrum squamose, and the antenne inserted rather more distant from the apex. (33) Pascoe, Ann. Mus. Civ. Gen., 1885, p. 265. 309 Mr. Davey has taken the species in South-West Victoria, ‘5+) and his specimens are evidently in better condi- tion than the type “5) (which by the glossy condition of the granules and tubercles shows evidences of abrasion); their tubercles and even many of the granules being clothed with scales. A male that he sent from Ararat is considerably smaller (10 mm. only), and with the apical tubercles more distinct and subconical. POROPTERUS CONIFER, Boh. A Dorrigo specimen of this species has the two large subapical tubercles of elytra not diverging, but with their tips touching (probably due to an accident). Its prothorax has the median carina more pronounced, the four tubercles across the middie are larger than on the typical form, but smaller than on the variety prodigus. On the elytra the second and third tubercles, on the third interstice, are decidedly smaller than on both forms. At a glance it approaches some of the forms of ellipticus. OPHRYTHYREOCIS FERRUGINEUS, Ni. sp. Black; antennz and tarsi red. Densely clothed with rusty-brown scales, variegated with sooty ones, and with numerous stout suberect ones scattered about. Head with dense concealed punctures. Eyes latero- frontal and small, but not very prominent. Rostrum rather wide, almost parallel-sided; with coarse concealed punctures almost to apex, which is densely punctured. Prothoraz rather lightly transverse, sides strongly rounded, apex about half the width of middle; with dense more or less concealed punc- tures. Hlytra subcordate, sides distinctly rounded; with rows of large partially-concealed punctures, becoming smaller pos- teriorly. Third and fourth segments of abdomen very short, and distinctly depressed below level of second and fifth. Femora stout, very feebly dentate. Length, 34 mm. Hab.—Victoria: Gippsland (E. W. Ferguson). On the prothorax all the scales are rather stout and sub- erect, although shorter than the erect ones on elytra. There are eight spots (two fairly large ones at base, four across middle, and two very feeble ones at apex) where sooty scales are condensed so as to appear like fascicles, although they are not longer than the surrounding rusty-coloured ones. On the elytra there is a rather large spot of sooty erect scales on each side of base, and numerous smaller ones (mostly on the (54) It 1s now first recorded from the mainland. (35) Kindly sent to me for re-examination by Mr. Simson. 360 even interstices) giving an appearance as of numerous feeble fascicles. The legs are also feebly ringed with sooty scales. The type appears to be a male. OPHRYTHYREOCIS MICROPS, Nn. Sp. Blackish; antenne and tarsi red. Rather densely clothed with ‘muddy-brown or muddy-grey scales, with some stout suberect ones scattered about, and in places forming feeble fascicles. Head rather convex, and with concealed punctures in front; forehead somewhat sinuous and bald where normally concealed. Eyes latero-frontal, small, and prominent. Rostrum moderately long, somewhat dilated in front of antennz (which are situated at the apical two-fifths), with a short, shining, impunctate median line, elsewhere with dense and rather coarse punctures, concealed only about extreme base. Prothorax moderately transverse, apex more than half the width of middle; punctures dense but concealed. Hlytra briefly subcordate, base truncate, sides strongly rounded; with rows of moderately large partially-concealed punctures ; interstices feebly subtuberculate beneath fascicles. Third and fourth segments of abdomen level with fifth, and but slightly depressed below second. /Jemora stout, grooves and teeth extremely feeble. Length, 24 mm. Hab.—Australia (A. Bovie). The erect scales are less numerous than on the other known species, and the fascicles are extremely feeble; of the latter six may be traced on the prothorax, and several across the base and middle of elytra. The type is almost certainly a female. BHODONTOCIS, n. g. Head of moderate size, partially concealed. from above. Eyes rather small, widely separated, coarsely faceted. Rostrum rather long and thin, moderately curved. Antenne thin; scape inserted slightly nearer apex than base of rostrum; two basal joints of funicle elongate; club ovate. Prothorax transverse, sides rounded, apex produced. Scutel- lum small. EHlytra with sides rounded to beyond the middle, sides thence arcuate to apex, base trisinuate. Pectoral canal deep and wide, terminated between middle coxe. Mesosternal receptacle rather widely U-shaped, feebly raised; cavernous. Metasternum about half the length of the following segment ; episterna narrow but traceable throughout. Abdomen with two basal segments large, the suture between them incurved to middle, third and fourth combined about the length of second and fifth, and not depressed below them. Legs rather long; femora not grooved; tibie lightly bisinuate. 361 At first the species described below appears to belong to Brachyporo pterus,$) from which (and also from Poropterus) it is distinguished by its metasternal episterna. At a glance it appears close to P. montanus, but the shoulders are very different. The femora are very minutely dentate, and the teeth are concealed by clothing, but even when this has been abraded they are seen with difficulty; but regarding them as dentate the genus would be associated (37) with Anlaws which has strongly dentate femora, and is otherwise very different. Regarding them as edentate, it would be associated with Orthoporopterus, to which it is not at all close. In general it is much like a Nechyrus, but the eyes and mesosternal receptacle distinguish it from that genus. BZODONTOCIS MEGAPHOLUS, N. sp. Black; antennze and tarsi obscurely reddish. Densely clothed with large, soft, muddy-brown or muddy-grey scales ; with stout suberect ones, condensed into fascicles on upper- surface and thickly distributed on legs. Head with dense normally-concealed punctures. Rostrum as long as prothorax, sides very feebly incurved to middle; with dense and rather small but clearly-defined punctures, smaller and sparser in middle than elsewhere. Prothoraz moderately transverse, sides strongly rounded, apex more than half the width of middle; with a short distinct median carina; with feeble swellings supporting feeble fascicles; with normally-concealed punctures. Hlytra not twice as long as wide, shoulders somewhat produced, apex obtusely notched ; with rows of very large partially-concealed punctures, third and fifth interstices with feeble tubercular swellings. Under- surface with rather small but usually distinct punctures. Length, 61-65 mm. Hab.—New South Wales: Dorrigo (H. W. Cox). On one specimen the metasternal episterna are quite dis- tinct, but on another, owing to a slight displacement of the clothing, they are indistinct. The suture between the two basal segments of abdomen is quite distinct across the middle, although not deeply impressed there. The hind femora, when placed in a line with the sides of the elytra, just pass their tips, but unless so placed appear to be shorter. As the cloth- ing of the rostrum is confined to the extreme base, it 1s prob- able that both the typical specimens are females. On the sides of the prothorax the scales are larger than elsewhere. (36) Near which it should be placed in catalogues. (37)In a (at present unpublished) table of the allies of Poropterus. 362 On the abdomen the clothing is very sparse and mostly sooty. There is a distinct tubercle on the third interstice about the middle, marking the summit of the posterior declivity, but elsewhere the tubercles are ill-defined. AMORPHOCIS, n. g. Head of moderate size, partially concealed from above; forehead evenly convex. Kyes rather small, widely separated, coarsely faceted. Rostrum wide, lightly curved. Antenne thin; scape inserted nearer apex than base of rostrum; two basal joints of funicle elongate; club ovate. Prothoraz trans- verse, base truncate, sides strongly narrowed to apex; ocular lobes acute. Scutellum absent. Hlytra truncate at base, widest at basal third, thence strongly narrowed to apex. Pectoral canal deep and wide, terminated close to front coxe. Mesosternal receptacle suddenly and strongly elevated, emar- gination feebly curved, hind margin with a perpendicular median ridge; cavernous. Metasternum about two-thirds the length of the following segment; episterna not traceable. Abdomen fairly large, sutures straight, first segment as long as three following combined, these equal inter se, fifth moderately long. Legs moderately long; femora strongly grooved, tibiz compressed; tarsi wide, third joint deeply bilobed. | In some respects close to Zenoporopterus, near which, perhaps, it should be placed, but mesosternal receptacle elevated, much as in the allies of 7dotasia, second segment of abdomen no longer than third, and metasternal episterna concealed. The typical species has curiously sculptured elytra. Its femora, when viewed from in front, appear to be dentate, but when viewed from behind the front ridge of each is seen to be nowhere dentate, but, at the usual position of a femoral tooth, each has a small fascicle of scales. The four hind tibie are also peculiarly clothed. AMORPHOCIS MIRUS, 0. sp. Black; upper -surface rather sparsely and irregularly clothed with greyish scales. Abdomen, metasternum, and parts of mesosternum very densely clothed; legs moderately clothed in places, densely in others. Head with dense more or less concealed punctures ; ocular fovea fairly large, and less frontal than is usual. Rostrum about twice and one-half as long as greatest width, sides dis- tinctly incurved to middle, deeply notched on each side of base ; basal three-fourths with rows of large punctures, separated by feeble ridges; apex with smaller and crowded punctures. 363 Scape about as long as funicle. Prothorax moderately trans- verse, subconical, apex about one-third the width of base ; with rather dense but irregular punctures; with a conspicuous median carina, continued to apex but not to base; with four small tubercles across middle, but the lateral one very feeble, and two small ones on each side of apex. Flytra subcordate, not twice as long as greatest width, sides strongly dilated from base to basal third, and then narrowed to apex ; with irregular rows of fairly large punctures; before middle with an irregu- larly transverse (or oblique) row of feeble tubercles, beyond same (except the suture) glabrous and with a few small tubercles. Punctures of wnder-surface concealed. Femora with dense punctures, the tibiz with distinct ridges. Length, 5 mm. Hab.—New South Wales: Blue Mountains (EK. W. Fer- guson). The antenne and tarsi are almost as black as the other parts. At the base of each of the four hind tibiz there is a conspicuous ridge of stout scales that, becoming suddenly ter- minated, causes the tibia itself to appear angularly dentate at its outer base, but the derm is but feebly dilated there. The clothing of the side pieces of the mesosternum cause these to appear like three triangles, of which the median one is darker than the others. The elytra appear to be divided into two parts, the basal and smaller portion partly clothed (near the base part of it is irregularly glabrous) and the apical portion glabrous, but this portion extends irregularly along the sides to the base. The tubercles are small but distinct on the hinder parts, and confined to the third, fifth, and seventh interstices, elsewhere they are less distinct (small granules only), but not confined to those interstices. PSEUDOPOROPTERUS. Several additional species of this genus having been dis- covered, the original diagnosis needs amendment as follows : — Eyes with facets of variable size. Scape shorter than funicle, its insertion variable. Abdomen with second segment exca- vated or not, its suture with first usually indistinct across middle. Legs short or moderately long, hind femora extend- ing to or just passing apex of elytra. PSEUDOPOROPTERUS SULCIFRONS, n. sp. 3. Black; antennze and tarsi almost black. Densely clothed with scales of varying shades of brown; with some stout ones scattered about. Head with a conspicuous median groove extending almost to base; punctures concealed. Rostrum stout, rather lightly 364 curved, with dense and coarse punctures, distinct in front but partially concealed behind antenne. Antennz rather stout, inserted about two-fifths from apex of rostrum; scape about half the length of funicle and club combined. Prothorax slightly longer than wide, base very feebly bisinuate, sides feebly dilated to beyond the middle, and then strongly nar- rowed ; apical portion flattened, semicircular, depressed below, and scarcely half the width of middle; with numerous distinct granules; a vague depression along middle; punctures large, but more or less concealed. Hlytra very little wider than pro- thorax and not twice as long; with rows of large more or less concealed punctures, each containing a large scale; interstices more or less uneven, each with a row of distinct granules, nearly all of which have a wide scale. Two basal segments of abdomen with large deep punctures, the fifth with denser and smaller ones, third and fourth strongly depressed below level of others, first depressed in middle. Femora moderately long, ridged, edentate, rather widely grooved, hind pair extending almost to tip of elytra. Length, 11-13 mm. @. Differs in having the rostrum thinner, less curved, with punctures distinct almost to base; scape inserted in middle of rostrum; and basal segment of abdomen flat in middle. Hab.—Queensland: Cooktown (H. W. Brown). The scales are of three shades of brown: very pale-brown or fawn, covering about half of the surface; chocolate-brown, covering almost as much; and velvety spots of sooty-brown. Of the latter there are eight on prothorax, in two transverse series, the lateral ones rather small and indistinct ; the antero- discal ones larger and angular, the others elongate, narrow in front, dilated to and touching base. On each elytron there are three velvety spots on the third interstice (including an elongate one on the posterior declivity) and two postmedian ones on the fifth; the space between these is sometimes clothed with almost white scales. There are also some feeble velvety spots elsewhere, but on some specimens all, or most, of the elytral spots are indistinct. On the prothorax, however, the four discal ones are very distinct. The cephalic punctures are quite concealed, but on abrasion there are seen to be dense and rather small ones, and sparser and much larger ones. What appears to be the sutural interstice on each elytron is narrow, and partly conjoined to the second, with granules only on its basal half (but not about the base itself); the third is also irregular in parts, and it is difficult to decide as to whether an elevation at the base, with crowded granules, should be regarded as belonging to it, or to the second; each shoulder is slightly produced, and has a few granules. Many 365 of the lateral granules, both on prothorax and elytra, are opaque, and with a small shining centre. PLATYPOROPTERUS FETUS, N. Sp. Sparsely clothed with very fine reddish scales and with rather long and stout reddish ones, rather dense on apical por- tion of prothorax, and forming feeble fascicles on elytra.. Head, rostrum, legs, and apical segments of abdomen moder- ately densely clothed. Head and rostrum indistinctly punctate, but punctures evidently large. Rostrum stout, curved ; apical portion shining and distinctly punctate. Scape inserted two-thirds from apex of rostrum, the length of five following joints combined ; of these the second is slightly longer than the first. Prothorax subquadrate, flat, walls abruptly vertical, widest slightly in front of middle, sides straight to base, rounded to apex, base strongly bisinuate; lower flanks with a few moderately large punctures, disc impunctate. Hlytra twice the width of pro- thorax, widest across shoulders, which are slightly produced laterally, feebly decreasing in width to apical third, thence suddenly arcuate to apex, apex feebly rounded and half the width of prothorax ; suture near base with a few small shining granules; base near suture with a few large punctures, becoming small towards sides ; flanks strongly inwardly oblique and with three feeble rows of punctures. Posterior femora not extending to apex of abdomen. Length, 84 mm. Hab.—New South Wales (Macleay Museum). Very distinct on account of the subquadrate prothorax and wide elytra; these latter if truncated at apical third would be much wider than long. They are proportionately wider than the prothorax than in any other Australian species of the subfamily. ELZAGNA NODIPENNIS, Nh. sp. Black; antenne and tarsi obscurely reddish. Densely clothed with sooty scales, in parts with dingy whitish ones. - Head with concealed punctures. Rostrum rather short and stout, sides narrowed at antenne, in front of same with dense and coarse punctures, concealed elsewhere. Antenne stout ; scape inserted two-fifths from apex of rostrum, not half the length of funicle and club combined. Prothoraz almost as long as wide, sides strongly rounded, apex scarcely half the width of base; with dense, large, round punctures. Llytra scarcely twice the length of prothorax and the same width at base, sides feebly diminishing in width from base; with rows of large partially-concealed punctures; with numerous small rounded tubercles, more numerous on the third and 366 fifth interstices than on the others. Under-surface with con- cealed punctures. Abdomen with second, third, and fourth segments of almost even size. Legs rather long; hind femora extending to tip of abdomen. Length, 5 mm. fab.—Victoria: Birchip (J. C. Goudie, his No. 198). Readily distinguished from others of the genus by the numerous small tubercles; of these there are nine or ten on the third interstice of each elytron, and seven or eight on the fifth. The upper-surface is clothed with small sooty scales, closely applied to the derm, and giving the same a minutely granulated appearance. In places the scales are concealed by a greyish exudation, and on the prothorax there is a small pale spot on each side of the middle. On the basal flanks of elytra, sterna, basal segment of abdomen, and legs the scales are mostly of a dingy-white, with feeble stains of brown in places. In each prothoracie puncture there is a dark seta. ELZAGNA SQUAMIBUNDA, Pasc. Several specimens of this species differ from the normal form in being more or less largely mottled with brown. One specimen, from Carnarvon, has the upper-surface almost entirely dark, except for vague remnants of pale markings on the prothorax, and for three conspicuous spots on the elytra, one on each side at the basal third, and one on the posterior declivity. Its head, rostrum, and hind femora are also mottled with brown. Another specimen, from Tar- coola, has, on the prothorax, four dark rounded spots at the base, and two angular ones at the apex. Each of its elytra has a subquadrate one on the shoulder, and an angular one commencing at the middle, and terminated halfway down the posterior declivity; the suture from the base to the summit of the posterior declivity is of a paler brown, and the knees, base of rostrum, and two spots on head are also of a pale- brown. I have also seen a mottled specimen in the British Museum collection, from Hermannsburg (Central Australia), and another in Mr. Froggatt’s collection, from Hay. BRACHYPOROPTERUS MONTANUS, Ni. Sp. $6. Black; antenne and tarsi reddish. Densely clothed with rather large scales of various shades of brown, and in places compacted into fascicles. i Head with dense concealed punctures. Rostrum rather long and thin, sides lightly incurved to middle, apical third with dense and rather coarse punctures, elsewhere with coarser but concealed ones. Antenne rather thin; scape inserted one-third from apex of rostrum, almost the length of funicle. 367 Prothorax lightly tranverse, sides strongly rounded; with rather numerous more or less concealed punctures, but derm nude in small patches; with four fascicles across middle and two smaller ones at apex. Elytra at base very little wider than prothorax, but sides slightly dilated to about the middle, base strongly trisinuate; with rows of large partially- concealed punctures, becoming smaller posteriorly; third interstice with an elongated semi-double fascicle on basal fourth, a small one about middle, and a moderately large one crowning the posterior declivity; fifth with five fascicles, including one on shoulder and one halfway down the posterior declivity; some small ones elsewhere, including two at apex; a few small granules on basal portion of suture. Under- surface with fairly large but more or less concealed punctures. Basal segment of abdomen depressed along middle. Length, 6-7 mm. ©. Differs in having the rostrum slightly longer and thinner; punctures smaller and concealed only about base; antennz inserted not quite as close to apex of rostrum; and basal segment of abdomen convex in middle. Hab.—New South Wales: Blue Mountains (H. W. Brown and E. W. Ferguson). In general appearance nearer to.apicigriseus than to ver- miculatus, but larger, prothoracic sculpture, fascicles, and side pieces of metasternum different, rostrum and antennze somewhat longer and thinner, etc. In some respects it is much like some species of Hzithius, but the metasternal episternum on each side is represented by a triangular front piece only; each of these is clothed with paler scales than the surrounding ones, and so appears as a small spot. The facets of the eyes are rather coarse. The majority of the scales are of a muddy-brown or rusty-brown colour. On a rather wide median space on the posterior declivity they are paler than elsewhere, and on each side for a rather large but ill-defined subtriangular space they are rather darker than elsewhere, sometimes almost sooty. The fascicles are supported by tuber- cular swellings, but on the scales being abraded some of the swellings are seen to be very slight. OUROPOROPTERUS SQUAMIVENTRIS, Nl. Sp. 3. Black; antennz and tarsi reddish. Densely clothed with light-brown or fawn-coloured scales; with stout suberect scales interspersed, and in places compacted into fascicles. Abdomen with a large patch of sooty scales. Head wide; punctures concealed; a shallow depression ‘between eyes. Rostrum rather long and not very thin, sides rather strongly dilated to base and less strongly to apex; 368 basal two-fifths with concealed sculpture, elsewhere with dense and clearly-defined although rather small punctures. Scape inserted just perceptibly nearer base than apex of rostrum, about half the length of funicle and club combined; first joint of funicle slightly shorter than second. Prothoraxz slightly longer than wide, base rather strongly bisinuate, apex rather narrow and with a conspicuous median fascicle; with four feeble swellings, supporting fascicles, across middle; punctures concealed. Hlytra closely applied to and at base but little wider than prothorax, but distinctly dilated to beyond middle, and then arcuate to apex; with irregular rows of large more or less concealed punctures; third interstice with two large obtuse tubercles: one at basal fourth, the other beyond the middle; second and fifth each with a feeble submedian tubercle, some feeble ones elsewhere, but apices produced as two subconical fasciculated tubercles. Legs long; femora lightly but acutely dentate. Length, 74-8 mm. Q. Differs in being larger (84-9 mm.), rostrum thinner, clothed only about basal fourth, elsewhere shining (it is sub- opaque in the male) and with minute punctures; the antennez are inserted a trifle nearer to the base of rostrum, and the abdomen is slightly more convex. Hab.—Queensland: Brisbane (R. Illdge); Darling Downs (C. French); New South Wales: Tweed River, Bulli, and Gosford (H. W. Brown). Differs from diwrus in being smaller, in the apex of pro- thorax produced singly 8) instead of bifurcate, apices of elytra more acutely produced, and first joint of funicle slightly shorter than second instead of distinctly longer. The sooty patch on the abdomen covers most of the three apical seg- ments, but at the base of the second one it is encroached upon by three conspicuous triangles of paler scales. On the pro- thorax and elytra there are sometimes some small spots of sooty scales. From the sides the elytra appear to slope rapidly upwards to about the basal third, and then to more gradually slope downwards to the apex. The seventh inter- stice, for portion of its length, appears almost like an obtuse carina on some specimens. POROPTERELLUS ABDOMINALIS, 0. sp. Black; antenne and tarsi of a rather bright-red; tibiz — and apical margins of elytra reddish. Clothed with muddy- brown or grey scales. : Head bald and without punctures, except for a few rather large ones between eyes. Rostrum short and wide, sides (38) On one female the apical fascicle of the prothorax is divided down the middle, so as to appear like two narrow, almost conjoined, ones. 369 lightly incurved to middle; with fairly numerous punctures, small about apex, becoming larger to base. Scape stout, in- serted almost in middle of rostrum, about half the length of funicle and club combined. Prothorax feebly transverse, disc somewhat flattened; with large punctures, distinct on flanks, partially concealed towards same; a rather large, sub- quadrate, medio-basal space with smaller punctures than else- where; apical half with a feeble median carina. FHlytra not much longer than wide, about once and one-half the length of prothorax, sides strongly rounded; with rows of very large partially-concealed punctures; basal half with some rather large granules. Metasternum irregularly excavated in middle. Two basal segments of abdomen with large punctures, and with a very large one common to both in middle; fifth with a few rather large punctures. J/emora stout, rather strongly but obtusely dentate; hind pair extending almost to apex of abdomen. Length, 4 mm. Hab.—Queensland: Little Mulgrave River (H. Hacker). In general appearance the upper-surface is not much like that of intercoxalis, but the remarkable sculpture of the abdomen is almost identical. It differs also from that species in its shorter legs and scape, and stronger femoral teeth. The clothing on the type is probably somewhat abraded, and appears to be mixed with mud. Fascicles may be present on fresh specimens, as on the type there appear to be remnants of same. There is a rather large medio-basal space on the prothorax that is shining and without clothing, and is prob- ably normal. The bald, smooth portion of the head has a vague, bluish gloss. The sutural portion of the elytra is slightly advanced on to the prothorax, so that the base of the latter appears to be evenly curved instead of bisinuate. PACHYPOROPTERUS HUMERALIS, Nn. sp. ¢. Black; antenne and tarsi reddish. Densely clothed with light-brown scales, variegated with patches of darker ones; with numerous stout suberect scales scattered about, and in places compacted into fascicles. Head with dense partially-concealed punctures; forehead conspicuously quadrisinuate, median carina distinct. Eyes moderately large, with rather small facets. Rostrum rather Jong and thin, sides feebly incurved in middle; with dense punctures, rather small at apex, becoming larger towards and more or less concealed on basal two-fifths; with a narrow median carina. Antenne rather thin; scape inserted one- third from apex of rostrum, the length of funicle; second joint of funicle once and one-half the length of first. Pro- thorax moderately transverse, sides strongly rounded, base 370 strongly bisinuate, with four feeble fascicles across middle; with a feeble concealed median carina; punctures concealed. Scutellum small, transverse. LElytra subovate, base strongly trisinuate, sides dilated to beyond the middle; with rows of large partially-concealed punctures; sides vertical for a space of four interstices; with a small but distinct post-humeral tubercle, with a very obtuse swelling on basal fourth of third interstice, and a shorter one on fourth before the middle; with a few conspicuous granules on suture near base. Meso- sternal receptacle with thin U-shaped walls. Basal segment of abdomen shallowly depressed in middle. Legs rather long; hind femora extending almost to tip of abdomen. Length, 8-84 mm. Q. Differs in having the rostrum somewhat thinner, with smaller and sparser punctures, concealed only close to base, antennz inserted two-fifths from apex of rostrum, and basal segment of abdomen convex. Hab.—Tasmania: Frankford, Waratah, Wilmot. Differs from satyrus in its much smaller size, presence of a scutellum, more conspicuously quadrisinuate forehead, and U-shaped mesosternal receptacle. In general appearance it is fairly close to Heaymus australis, but the femora are edentate. On the prothorax a vague patch of dark scales is usually traceable on each side of the base, on the elytra there may usually be traced an irregular postmedian fascia of dark scales, and another between it and apex. On one specimen, however, the fascicles are broken up into small vague spots. The tibiz are usually very obscurely banded with light- and dark-brown scales. PALETICUS CONVEXICOLLIS, n. sp. Black; antenne and tarsi reddish. Rather densely clothed with scales of a light-brown (sometimes almost golden- brown) colour; interspersed with stout and in places suberect ones, in places forming fascicles. Head with concealed punctures; with a feeble median carina. Rostrum moderately long, sides incurved to middle ; basal third with rather coarse partially-concealed punctures, elsewhere shining and with small but clearly-defined ones. Scape inserted slightly nearer apex than base of rostrum, about the length of five following joints combined. Prothorax moderately transverse, rather convex, sides strongly rounded, apex scarcely half the width of base; punctures concealed. Elytra at base not much wider than prothorax, but dilated to beyond the middle, and then sides arcuate to apex; with irregular rows of large, distant, partially-concealed punctures, becoming small posteriorly ; interstices with feeble tubercular 371 elevations, mostly on the even ones. Basal segment of abdomen with a deep oblique impression on each side near base. Legs rather long; femora stout, strongly and acutely dentate, hind ones not extending to apex of abdomen. Length, 10 mm. Hab.—New South Wales: Bulladelah (H. J. Carter). Nearer to apicipennis than to any other described species, but with fascicles on the second and fourth interstices as on others. The stout scales are rather dense on the legs. On the prothorax there are four fascicles across middle, and two at apex. On each elytron there are three on the second inter- stice, two on the fourth, two or three on the sixth, and a few feeble ones elsewhere. I have not detached the head of the type, but towards the base (which is concealed by the pro- thorax) it evidently has a somewhat sinuous impression. It has no sutural granules, but this is probably not a constant feature. PALETICUS BASALIS, N. sp. Black; antenne and tarsi red. Densely clothed with light-brown or greyish-brown scales, variegated on the legs and sometimes elsewhere, with still paler scales; with stout scales scattered about, and in places condensed into fascicles. Head in front with concealed punctures and a very feeble median ridge, basal (concealed) portion glabrous, and with a feebly quadrisinuated outline. Rostrum long, sides some- what narrowed at middle; basal half with coarse more or less concealed punctures, elsewhere shining, and with small dis- tinct ones. Scape inserted slightly nearer apex than base of rostrum, almost the length of funicle; second joint of funicle distinctly longer than first. Prothorax with basal two-thirds gently rounded, apex more than half the width of middle; punctures concealed. E£lytra short, subcordate, base strongly trisinuate, sides obliquely dilated from base, then parallel to about middle, and then narrowed to apex; basal half with irregular rows of very large punctures, becoming small pos- teriorly ; third interstice with a rather large obtuse tubercle at basal third, and a smaller one about middle; fourth with an obtuse elongated swelling about middle; fifth with a small one about middle; sixth with one at basal third, and an obtuse one on shoulder, with rather large shining granules on basal third, or basal half, of suture. Basal segment of abdomen with a deep fovea on each side near base. Legs long; femora stout, strongly and acutely dentate, hind ones passing apex of elytra. Length, 54-6; mm. Hab.—New South Wales: Dorrigo (H. J. Carter and EH. W. Ferguson). Allied to cordipennis, but smaller, with sparser tubercles and different clothing. The clothing is much as on frontalis, 372 but that species has very different elytra. There are five specimens before me, three of which, evidently males, differ from the others in having the rostrum with the coarse punc- tures more advanced towards the middle of the rostrum, and the antenne inserted somewhat nearer the apex, the basal seg- ments of abdomen also are somewhat less depressed; but the differences are not very conspicuous. There are six feeble fascicles on the prothorax in the usual positions; on the elytra they crown each tubercle; many of the stouter scales are paler than the others and scattered at random, but they are more numerous on the suture and sides of elytra and on the legs than elsewhere. All the scales, however, appear to be easily abraded, as is the case with most species of the genus. The tubercles about the basal third of elytra are always distinct, but the others are sometimes very obtuse, and appear to be little more than parts of a conjoint swelling. PALETICUS SUBEREUS, Pasc. A specimen from Dorrigo differs from the normal form in having most of the scales sooty, instead of a rusty-brown. In addition it has a few flavous scales scattered about, and con- densed into six small spots on the prothorax. PALETICUS CORDIPENNIS, Pasc. In the original description of this species the scutellum was not mentioned. But in a redescription and table ©9) it was mentioned as being distinct. It is certainly present on two specimens now before me, but in the majority of specimens it is either very minute and below the level of the elytra or alto- gether absent. The subhumeral tubercle also varies, being very distinct on some specimens and feeble on others. On each side of the suture near the base there are usually some highly polished granules, varying in number from one to five, and seldom alike on both sides. A specimen from Dorrigo is unusually large (10 mm.), with a feeble tubercle on the third interstice on the posterior declivity, a rather conspicuous elongated one on the fifth about the summit of the declivity, and two small ones about the middle of the seventh. It has one shining granule on the right of the suture and two on the left. PALETICUS SUBPARALLELUS, Lea. A specimen from the Endeavour River evidently belongs to this species, but differs considerably from the type in its (39) Proc. Linn. Soc., N.S.W., 1898, pp. 211 and 216. 373 clothing. Its prothorax is densely clothed with spathulate reddish-brown scales, with three transverse, slightly-waved fascize of chocolate-brown scales; the first of these is compara- tively close to the base, and does not quite extend to the suture ; the second is almost exactly median, and the third rather close to the second ; the disc is supplied with a few white scales, but these become more numerous towards base and sides, on the posterior declivity they become linear in arrangement; each side of apex is marked by a small but distinct spot of white scales. The under-surface and legs are supplied with whitish scales, the femora, especially the hind ones, being distinctly ringed. The specimen is very beautiful, a most unusual occur- rence in the genus. OMYDAUS ROSTRALIS, nN. sp. Black; antenne and tarsi of a dingy-red. Moderately and somewhat irregularly clothed with scales, varying from almost white, through ochreous, to sooty. Legs and parts of under-surface densely clothed. Head with coarse partially-concealed punctures. Rostrum moderately long, strongly curved, sides distinctly dilated towards but triangularly notched at base; on basal third with coarse punctures, elsewhere shining and with small clearly- defined ones. Antenne stouter than usual; scape inserted not much closer to apex than to base of rostrum, and distinctly shorter than funicle; first joint of funicle slightly longer than second. /Prothorax flat, distinctly transverse, sides feebly rounded to near apex, which is suddenly and strongly narrowed and subtubular; with moderately large punctures, more crowded on sides than disc. Elytra flattened, not much wider than prothorax, base strongly trisinuate, subparallel-sided to beyond the middle; with rows of very large deep punctures, becoming smaller posteriorly. Under-surface with coarse, but in places more or less concealed punctures. Basal segment of abdomen widely concave. Femora stout, widely grooved, front pair moderately, the others feebly, dentate; tibie feebly com- pressed, especially the front pair; with rows of punctures separated by ridges, each with a small subapical tooth in addi- tion to the terminal hook. Length, 65 mm. Hab.—Queensland: Bloomfield River (C. French). In general appearance fairly close to oblongopunctatus, but femora with wider and deeper grooves, rostrum con- spicuously notched on each side of base, body flatter and punc- tures smaller. Swbfasciculatus, which is also a depressed species, is wider, with different punctures, alternate interstices of elytra elevated, etc. Contractus, whose rostrum is very similar at the base, is not quite so depressed, prothorax more 374 noticeably decreasing in width to base, and with distinct im- pressions. The type is almost certainly a male. Its rostrum is rather wider and more strongly curved, and the antenne stouter, than usual. On the upper-surface the sooty scales are perhaps in the majority, but owing to their colour they are but little conspicuous. On the under-surface the scales are dense and almost setose in character, on a space occupied by the four front coxe and the intercoxal parts of the meso- and metasternum. The prothorax is not carinated along middle, but from some directions a feeble median line can be traced. The punctures on the basal two-thirds of elytra are usually truncated at the base and rounded at the apex, so that they have a subconical appearance; towards the sides, however, they are more rounded. The front femora each have a moderately distinct tooth in the usual position, but in addi- tion, between this one and the base, there is a swelling in the form of a very obtuse tooth. OMYDAUS LONGUS, 0. sp. Black; antennz and claw joints obscurely reddish. Head coarsely punctured. Rostrum stout, moderately long, strongly curved, somewhat gibbous near base; with coarse punctures throughout. Antenne rather stout; scape inserted two-fifths from apex of rostrum, distinctly shorter than funicle; first joint of funicle slightly longer than second. Prothorazx flat, distinctly longer than wide, base strongly bisinuate, hind angles overhanging base of elytra, sides feebly increasing in width from base to near apex, which is suddenly and strongly narrowed; surface uneven and with coarse irregular punctures; with a narrow median carina. Elytra narrow, very little wider than prothorax, sides irregularly parallel, base strongly trisinuate, apex widely rounded, with large irregular punctures and irregular interstices. Under- surface with more or less concealed punctures. Basal segment of abdomen widely depressed, second very little longer than third. Femora stout, hind pair not extending to apex of abdomen. Length, 9 mm. Hab.—New South Wales: Byron Bay (C. Watson) ; Dorrigo (H. J. Carter). A narrow roughly-sculptured species with coarse punc- tures on rostrum even to the apex; it also slightly decreases in width from the antenne to base, a most unusual character in the subfamily. On the elytra the punctures are concealed, except on the sides, where they are large and round, but on abrasion the others are seen to be very large, suboblong, and in irregular double series, with the alternate interstices irregu- larly elevated or subtuberculate. The femora are neither a7d distinctly grooved nor dentate, but from certain directions very feeble ridges are visible along one side of each, and near the subapical notch each ridge is very feebly inflated, or rather suddenly terminated, so as to cause an appearance as of very feeble dentition. These characters, combined with the short second abdominal segment, seem to indicate that the species should be referred to Omydaus rather than to Pseuw- domydaus. In appearance it is like a very large Ps. tenuis, but that species has the second abdominal segment much larger. Of the species of Omydaus it is closest to «mpressi- collis, but that species is wider, with different clothing and with moderately distinct femoral teeth and grooves. There are two specimens before me, and both are very dirty, but the abdomen and rostrum are apparently alike in both. On one of them the clothing was evidently rather dense and mostly more or less ochreous, with spots and fascicles of paler scales, more noticeable on posterior declivity than elsewhere; on its elytra there are two oblique fasciz of sooty scales near the summit of the posterior declivity. Its front tibie are straight on the lower edge from near the base to the subapical tooth. The other specimen, in addition to being very dirty, is evidently greatly abraded, but the oblique patches of sooty scales are distinct. Its front tibie are trisinuate between the base and the subapical tooth, the basal sinus is feeble, the next is slightly more distinct and bounded at each end by a feeble tooth, but the next one is much more distinct. The difference in the tibiz is possibly sexual. OMYDAUS NIGROFASCICULATUS, Ni. sp. 6. Black; antenne and tarsi but feebly diluted with red. Irregularly clothed with rusty-brown and sooty scales. Head with a median carina and irregular punctures, fore- head quadrisinuate. Rostrum moderately long, distinctly curved, sides dilated towards but deeply notched at base; basal half with coarse punctures, elsewhere shining and with small clearly-defined ones. Scape inserted about two-fifths from apex of rostrum, somewhat shorter than funicle, two basal joints of funicle subequal in length. Prothorax about as long as wide, base strongly bisinuate, sides strongly rounded; surface very uneven, and with coarse crowded punc- tures; with a feeble median carina on apical half. Elytra not much wider than prothorax, base strongly trisinuate, sides gently rounded; with rows of large deep punctures, becoming small posteriorly; third interstice somewhat raised near base. Basal segment of abdomen gently concave, with large punc- tures. Femora stout, strongly dentate; tibie with distinct ridges, front pair obtusely dentate about middle, and with a 376 more distinct tooth near apex, apical hook rather long. Length, 84-9 mm. Q. Differs in having the rostrum slightly thinner, basal segment of abdomen gently convex, and median tooth of front tibiz more obtuse. Hab.—Queensland: Kuranda (H. W. Brown). From the same locality as parviceps, but prothorax, elytra, tibiz, etc., different. In general appearance is close to fuliginosus, but the elytral sculpture and clothing very different. From swbfasciculatus, to which it is perhaps closer, it differs in the curiously curved clothing of the third inter- stice; the front tibize are also somewhat different. The sooty scales are rather sparsely distributed on the upper-surface, but they form a conspicuous fascicle on each elytron on the second interstice at summit of the posterior declivity. On each elytron also the rusty scales form a conspicuous and slightly but distinctly curved line mostly on the third inter- stice, but commencing at the base of the second row of punc- tures and ending on the second interstice behind the sooty fascicle. On the prothorax also some of the scales appear to be in feeble lines. On both prothorax and elytra there are a few feeble spots of scales that are ochreous or almost stramineous in colour. The concealed base of the head is - nude and densely covered with small punctures. About the apex of the prothorax there is a rather wide shallow impres- sion, appearing double on account of the median carina. The elytral punctures are very large, and each is so impressed that it appears to slope down from apex to base, and the latter to be cavernous, the space between each is shorter than the punctures themselves, so that from some directions these appear to be separated by rows of obtuse granules. PSEUDOMYDAUS TENUIS, Lea. A specimen from Illawarra differs from the type in being smaller (4? mm.) and with the oblique subapical fascia com- posed of reddish instead of whitish scales. Its hind legs are drawn forwards so that portions (normally concealed) of the coxee are exposed, and seen to be densely clothed with ochreous scales. ANOPLOCIS, 0. g. | Head small but not concealed from above; forehead quadrisinuate. Eyes rather small, coarsely faceted, widely separated. Rostrum rather long and thin. Antenne rather stout; scape shorter than funicle, inserted about middle of rostrum; two basal joints of funicle moderately long; club subovate, sutures oblique. Prothorax about as long as wide, sides rounded, base strongly bisinuate. Scwtellwm indistinct 317 or absent. Flytra not much wider than prothorax, base tri- sinuate. Pectoral canal rather wide and deep, terminated between middle coxz. Mesosternal receptacle U-shaped, walls thin; open. Metasternum much shorter than the following segment; episterna very narrow. Abdomen large, sutures deep and straight, first segment as long as three following combined, second distinctly, but not by much, longer than third or fourth. JZegs rather short and stout; femora edentate, shallowly grooved; tibize dilated near apex; tarsi thin but rather short, third joint not much wider than second. Somewhat depressed, coarsely sculptured, and squamose. In general appearance the species described below is strik- ingly like an Omydaus, near which it should be placed; but the open mesosternal receptacle, edentate femora, and sinuous forehead forbid its being placed in that genus. The type being unique it has not been examined to see if wings are present. ANOPLOCIS FERRUGINEUS, N. Sp. Black ; antenne and tarsi of a dingy-red. Rather densely clothed. Head with coarse concealed punctures in front; forehead apparently trisinuate, but really quadrisinuate, with a feeble median carina. Rostrum as long as prothorax, moderately curved, sides feebly dilated from antennz to near base, but base notched on each side; basal half with coarse concealed punctures and a feeble median ridge; front half with small punctures. LProthorax lightly convex; coarsely and somewhat irregularly punctured; with a thin, continuous, median carina. Lilytra about twice as long as prothorax, irregularly subcordate, widest at about basal fifth ; with semi-double rows of very large punctures, becoming smaller and more regular on the sides and posteriorly. Length, 6 mm. Hab.—New South Wales: Comboyne (W. H. Muldoon). The type (as with so many specimens of the allied genera) has its clothing somewhat obscured by mud; but the majority of the scales are of a bright brick-red, with numerous paler ones scattered about, and the latter forming some spots about summit of posterior declivity (apparently the remnants of a transverse fascia) and on the sides towards base. Probably on specimens in perfect condition both the red and the pale scales form feeble fascicles, at least on the elytra. The base of the prothorax has the incurved parts highly polished, and fit- ting into each of these is a highly-polished elevated space at the base of the third interstice on each elytron. But it is probable that these polished spaces are normally concealed, as the type has its prothorax and elytra slightly separated. The punctures of the under-surface are mostly concealed, but on 378 the basal segment of the abdomen there are some large round ones ; the apical segment is shallowly bifoveate and apparently densely punctured. The type is probably a male, and to the naked eye appears to be of a rusty-red colour. DECILAUS INCONSTANS, 0. sp. 3. Black; legs (and sometimes the elytra) obscurely diluted with red; antennz and tarsi of a rather bright-red. Densely clothed with stout sooty scales, but more or less con- spicuously variegated with paler ones. Head with crowded partially-concealed punctures. Ros- trum short, stout, base wide, and distinctly notched on each side ; with large punctures in irregular series behind antenne, crowded in front of same. Scape short and stout, inserted almost in exact middle of rostrum, scarcely longer than two following joints combined ; these subequal in length, but the first wider than the second. Prothorax moderately transverse, sides strongly rounded ; with dense, round, partially-concealed punctures; with a short, feeble, median carina. LHlytra with sides moderately rounded, base trisinuate and distinctly (although not by much) wider than prothorax; with rows of rather large punctures. Jfesosternal receptacle elevated and almost truncate in front. Abdomen with dense and fairly large but more or less concealed punctures. Legs stout ; femora feebly grooved; tarsi rather narrow, but third joint deeply bilobed. Length, 43-5 mm. Q. Differs in having the rostrum slightly longer and thinner, scape inserted near base of rostrum, and abdomen with basal segment flat instead of gently concave. The prothorax is also slightly longer in proportion. HTab.—Victoria: Geelong (H. W. Davey); South Aus- tralia: Edithburgh and Port Lincoln (H. H. D. Griffith). Allied to perditus, and the rostrum similarly notched at base, but prothoracic scales nearly all thinner and not con- fined to their containing punctures; abdomen of male more concave, and of female less convex. The punctures are also different. The scales on the elytra are mostly sooty, but are sometimes largely mixed with dingy-brown ones, and usually with a few pale (almost white) ones. On the prothorax the scales are larger than on the elytra, and the sooty ones are less. predominant. On one specimen some of the pale prothoracic scales are white and others are almost carmine, especially at the base. On this specimen also the majority of the scales on the under-surface and legs are of a rather bright brick-red, but on most of the specimens the scales there are of a more or less pale-brown. The prothoracic punctures at first appear to be of rather small size for arg the genus, but on abrasion they are seen to be fairly large. The large elytral punctures are in rows but not in strie; they are considerably larger on the male than on the female. The interstices on abrasion are seen to be longitudin- ally strigose, and with numerous fairly large punctures, often forming a ring around one of the seriate ones; but their finer sculpture is normally quite concealed. They are usually nar- rower than the punctures in the male, but considerably wider in the female. DECILAUS VARIEGATUS, n. sp. d. Black; antenne and tarsi of a rather bright-red. Densely clothed with large soft scales, mostly fawn-coloured, but variegated with irregular patches of white and sooty ones. Head with crowded concealed punctures. Rostrum rather stout, sides regularly incurved to middle; punctures concealed except at extreme tip. Scape inserted almost in middle of rostrum, the length of three basal joints of funicle; of these the first joint is slightly longer than the second. Prothorax moderately transverse, sides strongly rounded; with dense, round, deep punctures, each normally concealed by its con- taimed scale. lytra briefly cordate, sides rather strongly rounded ; with rows of large, partially-concealed punctures, in moderate strie. Mesosternal receptacle strongly elevated like half of a ring. Abdomen with dense but normally-concealed punctures. Femora stout, lightly grooved and dentate. Length, 44-54 mm. Q. Differs in having the rostrum longer, thinner, and with punctures clearly defined owing to absence of clothing (except at extreme base); scape inserted slightly nearer the base of rostrum; and basal segment of abdomen convex, instead of flat, in middle. Hab.—South Australia: Henley Beach and Myponga (H. H. D. Griffith). The size and shape are exactly as in mixtus, but that species has unarmed femora and very different prothoracic clothing. Ovatus has the shape very similar, but the clothing is different ; on its prothorax few, if any, of the scales being directed forwards, and on the elytra there are stouter seriate scales amongst the ordinary ones. The femoral teeth are very sharp but small, and liable to be overlooked. The clothing gives the species a peculiarly soft appearance, so that it is the prettiest of all the beach-frequenting species. On the pro- thorax (where they are all directed forwards) and two basal segments of abdomen the scales are considerably larger than elsewhere. On the elytra the snowy scales are sometimes scat- tered singly amongst the others, or in small spots about the punctures, but on the basal half they usually form very 380 irregular patches, sometimes extending across two or three interstices. On the prothorax they usually form a very irregular line on each side. The sooty scales are less numerous than the snowy ones on the elytra, and are more compacted ~ into spots; but on the prothorax they usually occupy most of the disc, except for an irregular line of fawn-coloured ones along the middle. On the under-surface, legs, and head the clothing is less conspicuously variegated than elsewhere. The rostrum is clothed throughout in the male, but only at the sides of the base in the female. The elytral punctures are large, but are so obscured by the clothing that they appear to be much narrower than the interstices, whereas, except pos- teriorly, they are quite as wide, or wider. DECILAUS HYSTRICOSUS, n. sp. 3d. Of a dark reddish-brown; antennz and legs paler. Densely clothed with rather dingy fawn-coloured or muddy- brown scales, in places feebly variegated; with numerous stiff erect sete scattered about. Head wide; punctures concealed. Rostrum short and wide; punctures concealed behind antennz, but distinct in front of same. Scape stout, inserted almost in middle of rostrum, the length of two following joints combined; first joint of funicle dilated to apex, the length of three following combined. Prothorax lightly transverse, sides subparallel on basal half, thence coarctate to apex; with dense normally- concealed punctures. Hlytra very little wider than prothorax, base lightly trisinuate, sides feebly rounded to beyond the middle, thence rapidly diminishing in width to apex; with rows of large concealed punctures, in light strie. J/esosternal receptacle like half of an elevated ring. Abdomen with dense . but more or less concealed punctures. Femora stout, moder- ately grooved and lightly dentate; third tarsal joint wide and deeply bilobed. Length, 3 mm. Q. Differs in having the rostrum with smaller punctures and clothing terminated before antennz, scape somewhat thin- ner, and the basal segment of abdomen more convex. Hab.—New South Wales: Narara (HE. W. Ferguson). In general appearance close to noctivagus, but slightly less robust, with more numerous erect setz scattered about, and rostrum without clothing beyond insertion of antennz in male. All the femora are dentate, but the teeth are minute and in- visible from most directions. On the types there are four vague sooty lines on the prothorax, the setz (which are stouter and less erect than on the elytra) being almost confined to them. On the elytra there is a feeble, pale (on one specimen almost white) oblique stripe from near each shoulder to near 381 the suture, just before the middle, so that the two together look like a wide feeble V; there are also even more vague remnants of other fasciz. The sete (which are very con- spicuous from the sides) are usually of the colour of the scales amongst which they are set. On the legs stiff (and mostly pale) sete are thickly scattered amongst the scales. The basal joint of the funicle is long, but not thin. The third interstice on each elytron appears to have two feeble swellings, on each of which the erect setee form a feeble fascicle. DECILAUS BRYOPHILUS, N. sp. 3. Black; rostrum and legs diluted with red, antenne and tarsi paler. Densely clothed with brick-red scales, variegated with patches of paler and sooty ones; mesosternal receptacle, metasternum, and two basal segments of abdomen with rather dense, thin, golden setz. Head with a semicircular space in front densely clothed, but bald elsewhere. Rostrum rather wide, ridged along middie, notched on each side of base; with dense punctures more or less concealed behind antenne. Antennz thin; scape inserted one-third from apex of rostrum, slightly shorter than funicle; club rather large. Prothorax moderately transverse, sides strongly rounded, apex more than half the width of base; with dense partially-concealed punctures. Hlytra sub- cordate, base truncate, closely applied to and no wider than prothorax; sides strongly rounded, widest at about basal third, thence strongly diminishing in width; with rows of large partially-concealed punctures in moderate striz. Jeso- sternal receptacle rather strongly raised, emargination trans- verse. Abdomen with dense and fairly large but partially- concealed punctures, and forming one regular row across each of the third and fourth segments, basal segment with a shallow depression common to it and to metasternum. Femora stout, especially the hind pair, and strongly grooved; third tarsal joint wide and deeply bilobed. Length, 24-24 mm. Q. Differs in having the rostrum longer, with sparser clothing and smaller punctures; clothing of under-surface normal, basal segment of abdomen convex, and prothorax less transverse. Hab.—Tasmania: Hobart and Mount Wellington, in moss (H. H. D. Griffith and A. M. Lea). A small prettily-variegated species, with unusually wide hind femora. The prothoracic scales are longer than on the elytra and but feebly variegated, on the elytra there are several small irregular patches of snowy scales, and the suture (except on the basal third, where it is glabrous) has two con- spicuous rows of similar scales; there are also small sooty 382 patches scattered about. On the head there is a pale spot between the eyes; the clothing of the legs is but feebly variegated. The base of the head (concealed when set out but still attached to the body) is quite bald. On both speci- mens parts of the three lateral interstices of each elytron are glabrous; but this is probably due to rubbing by the femora. DECILAUS PARVONIGER, 0. sp. Deep shining-black; head, rostrum, legs, and front of prothorax more or less obscurely diluted with red; antenne and tarsi paler. Sparsely clothed on abdomen, legs, and between eyes, elsewhere almost or quite glabrous. Head with some coarse punctures in front, elsewhere shining and with minute punctures. Eyes separated about half the width of base of rostrum. Rostrum short and stout, sides distinctly incurved to middle; basal half with rows of punctures separated by ridges, apical half with crowded punc- tures. Scape inserted nearer base than apex of rostrum, much shorter than funicle; club large. Prothorax strongly trans- verse, sides strongly rounded, apex more than half the width of base; base, sides, and apex with fairly large punctures, smooth and impunctate across middle. Hlytra briefly sub- cordate, base truncate, sides strongly rounded and widest at about basal third; with rows of not very large punctures, -in distinct strie; interstices wider than strie. Mesosternal re- ceptacle wide and truncate. Abdomen irregular; with rather large punctures. Memora rather long and strongly grooved, front pair somewhat inflated near base; tibie angular, but not inflated at base. Length, 14 mm. Hab.—New South Wales: Wollongong, in rotting leaves (A. M. Wea). A curious minute black species, in size like mzrabilis, but with very different sculpture. The mesosternal receptacle is decidedly aberrant. The sides of the elytra are rather curi- ously curved between the middle and apex of each. The first segment of the abdomen is large, concave in middle, and with the intercoxal process wide; the second is short, with its apex almost vertical; the others are short and depressed, the fifth not as long as the third and fourth combined. DECILAUS NIGRONOTATUS, N. Sp. Of a dingy reddish-brown; elytra with blackish spots; antenne of a rather bright-red, but club black. Clothed with stramineous sete or thin scales, forming three lines on pro- thorax, and a spot on each side of scutellar region, but rather sparse elsewhere. 383 Head with rather dense but more or less concealed punc- tures; base bald and shining. Rostrum rather long and stout, sides lightly incurved to middle; behind antenne with rather strong punctures in four distinct rows, the two median rows separated by a shining space that dilates considerably in front of antennz. Scape inserted about one-third from apex of rostrum, slightly shorter than funicle; club large. Pro- thorax strongly transverse, sides strongly rounded, apex more than half the width of base; with dense partially-concealed punctures. Hlytra subcordate, base truncate, sides strongly rounded and widest across basal third; with rows of large but ill-defined punctures, in moderate striz; interstices wider than striz, finely wrinkled, and punctured. Mesosternal re- ceptacle like the third of a strongly elevated ring. Abdomen with rather coarse punctures on first, second, and fifth seg- ments. Femora stout, moderately grooved, and edentate; tibie angular at outer base. Length, 13-2 mm. Hab.—Tasmania: Mount Wellington, fairly common in moss (H. H. D. Griffith and A. M. Lea). A small, elliptic, opaque species; much the shape of the preceding one, but somewhat larger and very differently clothed; club conspicuously black, etc. Each elytron has a large dark spot on the side, three spots on the third inter- stice (but the hind one sometimes missing), and one on the fifth ; the latter is sometimes connected from each end with the lateral spot, so as to enclose a rounded reddish space, but it sometimes appears simply as the inner end of the lateral spot. With the head set out its polished base is entirely con- cealed. The third and fourth segments of abdomen at first appear to be impunctate, but from behind a row of fairly large punctures can be traced across each. DECILAUS NIGRICLAVUS, N. sp. Of a dingy-red, club black; prothorax and elytra with dark spots. Sparsely clothed with stramineous sete or thin scales. Head with partially-concealed punctures in front; base bald. Eyes separated about three-fourths the width of rostrum at base. Rostrum moderately long and stout, sides incurved to middle; with four rows of strong punctures behind antenne, but more crowded and smaller in front. Antenne much as in preceding species. Prothorarx strongly transverse, sides strongly rounded; densely and coarsely punctured; with a distinct median carina. Hlytra sculptured as in preceding species. Jfesosternal receptacle like half of a strongly-elevated ring. Abdomen with coarse punctures, but forming a row across each of the third and fourth 384 segments; basal segment feebly depressed in middle. Pemora stout, moderately grooved, and lightly dentate; tibize sub- angular at outer base. Length, 1? mm. Hab.—Tasmania: Mount Wellington, in rotting leaves (A. M. Lea). In general appearance very close to the preceding species, with which I had it confused, but femora distinctly, although not strongly, dentate. On each elytron of the type there is an obscure spot on the side, one on the fifth interstice, and another on the third, the three seeming to form a feeble oblique fascia; there are also vague remnants of two others on the third interstice, and of others on the sides of the pro- thorax. But probably the markings are more or less variable. Its clothing is not condensed into lines on the prothorax, nor into spots at the base of the elytra, but this may be due to partial abrasion. DECILAUS STRIATUS, N. sp. 3. Black; legs (and sometimes head and rostrum) of a dingy reddish-brown; antenne and tarsi paler. Clothed with long but rather sparse, stout, yellowish seta or elongated scales. Head with coarse punctures in front, elsewhere shining and with minute punctures. Eyes separated about two-thirds the width of rostrum at base. Rostrum stout, moderately long; apex shining and minutely punctate, elsewhere with coarse punctures in four series. Scape inserted about two- fifths from apex of rostrum, somewhat shorter than funicle; club large. Prothorax moderately transverse, sides strongly rounded ; with dense clearly-defined punctures. /Llytra sub- cordate, sides strongly rounded and widest across basal third ; deeply striated, punctures in striz conspicuous on sides, but not sharply-defined elsewhere; interstices wider than striz, with numerous small punctures. J/esosternal receptacle like the third of a strongly-elevated ring. Metasternum with a thickened impunctate space on each side. Abdomen large, with rather dense and large punctures; basal segment with a wide shallow impression, common to it and to metasternum. Femora stout, rather strongly grooved, and edentate. Length, 2-21 mm. @. Differs in having the rostrum thinner and with smaller punctures, and basal segment of abdomen gently convex. Hab.—Tasmania: Mount Wellington, fairly common in moss (H. H. D. Griffith and A. M. Lea); Waratah (Lea). Allied to the two preceding species, but black and more elongate, and a greater portion of the head bald, so that 385 even with the head retracted some of the bald portion is visible. Each of the metasternal episterna appears to be thickened at its suture with the metasternum, so that a fairly conspicuous impunctate ridge appears, between which and the elytron is a fairly distinct row of punctures; as the ridge is without a triangular frontal projection it probably belongs to the metasternum itself. The tips of the prothorax and of the elytra are sometimes diluted with red. On the pro- thorax there are usually three feeble lines of sete; on the elytra the clothing is mostly compacted into fairly numerous but feeble fascicles. DECILAUS SUTURALIS, 0. sp. Black; antennz and tarsi reddish. Prothorax with sooty varied with greyish and stramineous scales, nearly all elevated above the derm; elytra with dense sooty scales, closely applied to derm, but feebly variegated with pale ones, and with some stiff suberect white and sooty scales scattered about. Under- surface with stiff white or whitish scales; legs with clothing mostly sooty, head in front and basal half of rostrum with stout pale scales. Head with coarse partially-concealed punctures; basal part bald. Eyes separated the width of rostrum at base. Rostrum stout, rather short, with dense and coarse punctures, partially concealed but seriate in arrangement behind antennz, and with a narrow median carina. Scape inserted one-third from apex of rostrum, almost the length of funicle; club large. Prothorax moderately transverse, sides strongly rounded, apex about two-thirds the width of base; with dense, deep, and fairly large punctures. Llytra rather long, sub- cordate, sides strongly rounded and widest at basal fourth; with rows of large partially-concealed punctures, in distinct strie. Iesosternal receptacle strongly elevated and rather lightly curved. Abdomen with dense partially-concealed punctures, third and fourth segments somewhat depressed. Femora stout, strongly grooved, edentate. Length, 2 mm. Hab.—Tasmania: Mount Wellington (type in H. H. D. Griffitth’s collection). The size and colour similar to the preceding species, but clothing very different. The ridge at the side of the meta- sternum is thinner, but being clothed with pale scales is rather more conspicuous. The elytral margins, except in middle, are somewhat thickened and feebly shining. The type appears to have a vague remnant of a median prothoracic carina. As the basal segment of its abdomen is flattened in the middle it is probably a male. The seriate punctures are very distinct N 386 on the sides of the elytra, owing to the scales being sparser there than elsewhere; the basal half of the suture is shining. - DECILAUS ALBONOTATUS, 0. sp. Bright reddish-castaneous; club black. Moderately densely clothed with ochreous scales, variegated with white and sooty. Head rather wide, with concealed punctures on a small semicircular space in front; elsewhere bald and minutely punctate. Eyes separated almost the width of rostrum at base. Rostrum moderately long and rather wide, sides dis- tinctly incurved to middle, with a narrow median carina; with dense punctures, becoming concealed towards base. Scape inserted about two-fifths from apex of rostrum, about the length of the five following joints; club large. Prothorax about as long as wide, sides rather strongly rounded, apex more than half the width of base; with dense more or less concealed punctures. Hlytra subcordate, sides strongly rounded and widest at basal third, with rows of large partially-concealed punctures, in light striz; interstices wider than strie; margins shining, and on shoulders thickened. Mesosternal receptacle moderately elevated in front; apex semicircular. Abdomen with moderately dense punctures. Femora stout, rather strongly grooved, and edentate. Length, 2mm. Hab.—Tasmania: Waratah, in moss (A. M. Lea). The clothing is very different to that of the preceding species, but somewhat similar to that of bryophilus, whose metasternum, however, is very different. The ridge on each side of the metasternum is more distinct than on either of the preceding species; it appears to be narrow and parallel-sided, but with a feeble median curve, between it and the elytron is a partially-concealed row of punctures. The elytral margins are lightly thickened and polished, especially at the base, where the shining portion is about the width of the meta- sternal ridge. On the elytra the scales are nearly all closely applied to the derm; the white ones clothe the shoulders and form a feeble oblique stripe on each side, from near the shoulder to the suture just beyond the middle, and form a few feeble spots posteriorly. Close behind the stripe there are a few sooty scales; but the disposition of the white and sooty scales differs on the right and left elytra. On the prothorax the scales are longer and stouter, the white ones form a dis- tinct spot on each side, and a few spots on the lower sides. There are a few white scales between the eyes. On the legs and under-surface the scales are subsetose and uniform in colour. The head is conspicuously bald, except for a rather 387 small frontal space. As the basal segment of its abdomen is moderately convex the type is probably a female. DECILAUS LATERALIS, 0. sp. Of a dingy reddish-brown, in parts almost black ; legs and elytral margins dull-red, antenne paler. Rather densely clothed. Head with dense punctures, concealed only on a small medio-frontal space. Eyes separated the width of rostrum at base. Rostrum rather short and wide, sides lightly incurved to middle; with coarse and dense punctures, partially con- cealed towards base. Antenne much as in suturalis. Pro- thorax moderately transverse, sides strongly rounded, apex more than half the width of base; with crowded partially- concealed punctures. JHlytra subcordate, sides strongly rounded and widest near base, margins shining, near apex strongly thickened, and near base very strongly thickened ; with rows of partially-concealed punctures. MJesosternal recep- tacle like one-third of a moderately elevated ring. Abdomen with dense more or less concealed punctures. Femora stout, strongly grooved, and edentate. Length, 2 mm. Hab.—Tasmania: Mount Wellington (type in H. H. D. Griffith’s collection). Allied to the three preceding species, but with the curious metasternal ridges and polished sides of elytra reaching the maximum. Hach ridge slightly dilates from its hind to its front end, but the latter is not triangularly produced inwards ; it is gently curved, with the convex side near the elytra (in the preceding species the reverse is the case), and it is rather densely clothed. The margins of the elytra are conspicuously polished and thickened, especially at the base, where they appear to be curved backwards so as to be quite distinct when viewed from above. ‘The clothing of the under-surface is peculiar, but probably varies sexually ; the type is almost cer- tainly a male. On the elytra the scales are closely applied to the derm and are ochreous, variegated with white, and with stout suberect ones scattered about; on the prothorax the scales are also ochreous and white, but the latter form three fairly distinct lines. On the under-surface the clothing mostly consists of elongate silvery setz, which are denser and more conspicuous on the metasternum and two basal segments of abdomen than elsewhere. The punctures on the bald portion of the head are very distinct, although not very large. DECILAUS LONGIROSTRIS, 0. sp. Of a dingy-red, in places blackish; antennz of a rather pale-red. Densely clothed with rounded scales, varying from N2 388 a very pale-fawn colour to sooty; with numerous stout scales scattered about, and in places compacted into fascicles. Head with numerous and mostly-concealed punctures; with a feeble medio-basal ridge. Rostrum long and thin, sides lightly incurved to middle; with rather dense and not very small punctures, more or less concealed on basal third. Antenne thin ; scape inserted two-fifths from apex of rostrum, the length of funicle; second joint of funicle distinctly longer than first. Prothorax moderately transverse, sides strongly rounded, base bisinuate and more than twice the width of pro- thorax ; with a very feeble median ridge. Hlytra rather short, sides dilated to beyond the middle, base trisinuate, median sinus small, the others large, shoulders clasping prothorax ; with rows of large round punctures, becoming smaller pos- teriorly ; interstices not separately convex, with feeble swell- ings supporting fascicles. Legs rather short; femora stout, moderately dentate. Length, 9 mm. Hab.—New South Wales: Ebor (R. J. Tillyard). In general appearance strikingly close to the variety A of Poropterus rubeter, but rostrum much longer and thinner, abdomen not sulcate, and femora dentate. The long rostrum (it is distinctly longer than the prothorax) seems as much out of place in Decidlaus as in Poropterus, but it has been referred to the former on account of its femoral armature. The outlines of the upper-surface are much as in D. auricomus and D. bifurcatus. 'The dark parts of the derm are a rather wide median space on the prothorax; and on the elytra a rather wide medio-basal space, narrowed at the basal third, and then dilated so as to extend to about six interstices from the suture. The rostrum is black, but diluted with red in front. The type is evidently in perfect condition, but it is probable that the derm on other specimens will be almost or entirely black. As the basal segment of its abdomen is gently convex in the middle, it is probably a female. On the upper-surface the darker parts are mostly clothed with dark scales, and the paler parts with pale scales, so that these parts are quite distinct to the naked eye. Many of the paler scales on the elytra have a faintly opalescent gloss. On the prothorax the stout scales are numerous about the apex, and form four feeble fascicles across middle. On the elytra they form feeble fascicles on the third and fifth interstices, and are numerous at the apex, and on the seventh interstice, and on the apical third of suture. On the abdomen and legs the pale and dark - brown scales appear to be mixed together in small spots. The prothorax has not been abraded, but portions of its derm are normally visible, and are without punctures. 389 DECILAUS AURICOMUS, Lea. Var. victoriensis. Mr. H. W. Davey has taken sexes of a species from the Western District of Victoria that appear to represent another variety of awricomus. In colour the male agrees with the variety zmsularzs, but it differs from that variety and from the typical form in having the prothoracic punctures considerably larger. Its female differs from its male in having the golden clothing of the under-surface replaced by stout (stouter on abdomen than on the metasternum), depressed, white scales; the two basal segments of abdomen convex and the rostrum thinner, with smaller but more clearly-defined punctures, and clothed only at extreme base and in the sub- lateral sulci. Var. (2) tasmaniensis. A specimen from Hobart probably represents another variety. Its colour and the clothing of its upper-surface are much as in the variety imsularis. It appears to be a female, as its rostrum is as in the above-noted female, but it differs decidedly from both sexes of that variety in the clothing of two basal segments of abdomen; the scales there are thin, elongate, and decumbent; on the metasternum they are still thinner, although far from being hair-like, as in the males. DECILAUS CUNICULOSUS, Lea. Mr. Davey has taken sexes of this species in the Western District of Victoria. The female differs from the male (type) in having the rostrum slightly longer and thinner, with smaller and sparser but more clearly-defined punctures, the legs slightly shorter, and basal segment of abdomen less concave. DECILAUS PERDITUS, Pasc. In this species the rostrum is triangularly notched on each side of the base, but the notches are normally more or less concealed by clothing. On examination from the under- surface, however, they are very distinct. Several other species (litoralis, ovatus, and sobrinus) have similar but less distinct notches. Mr. Pascoe recorded the species from Western Aus- tralia and Victoria; it also occurs in Tasmania (Ulverstone) and South Australia (Henley Beach and Edithburgh). Eight specimens, taken at roots of beach-growing plants near Sydney, are entirely without white scales, the brownish ones nowhere condensed into spots or fasciz, and (except on prothorax) nowhere distinct. A specimen from Ocean Grove (Victoria) possibly belongs to the species, but its mesosternal receptacle is almost V-shaped and almost open, its hind margin being no thicker than the sides; in fact, not as thick as the apices. This is possibly an 390 abnormality, or due to an accident, but on the specimen it has every appearance of being natural. RoOPTOPERUS FULIGINEUS, Ni. Sp. 3. Black; antenne and tarsi red. Densely clothed with scales, usually of a muddy-brown colour, but sometimes sooty ; on elytra, and sometimes on prothorax, variegated with spots of paler scales. Under-surface usually with paler scales than on upper-surface. Femora and tibize more or less distinctly ringed. Upper-surface with numerous fascicles. Head densely clothed in front; forehead bald and shining. Rostrum feebly curved, rather wide at base, sides lightly in- curved to middle ; behind antennze with coarse concealed punc- tures, and a feeble median carina; in front of same shining, and with minute punctures. Scape short, inserted slightly nearer base than apex of rostrum. Prothorax almost as long as wide, sides moderately rounded; with rather large and round, but usually concealed, punctures. Llytra strongly tri- sinuate at base, sides moderately rounded, and widest just before middle ; with large partially-concealed punctures ; inter- stices with feeble tubercular swellings, supporting fascicles ; of these there are three on the third interstice, four on the fifth, three on the seventh, and a few feeble ones elsewhere. Under- surface with large partially-concealed punctures; basal seg- ment of abdomen widely depressed in middle, the second flat. Length, 34-4 mm. Q. Differs in having less of the rostrum clothed and the two basal segments of abdomen convex. Hab.—Tasmania: Epping Forest, Mount Wellington (H. H. D. Griffith); Ulverstone, Stanley (including summit of “Nut”’); Waratah (A. M. Lea). Close to tasmaniensis, but with more of the head bald and with a distinct pale spot on the middle of each elytron, and one on each side; that species also has two fascicles crowning the posterior declivity considerably larger than any others, and usually paler. On the present species the fascicles there are no larger than several of the others. The rostrum and under-surface are sometimes quite as black as the other parts, but are usually obscurely diluted with red. On the prothorax there are ten fascicles; two very feeble ones at apex and eight loose ones in two transverse series, the four median ones are sometimes paler than the lateral ones. On the elytra the fascicles are more conspicuous and are frequently composed of sooty scales. In addition to the fascicles there are many erect scales scattered about. The under-surface is densely clothed, and in addition each of the large punctures contains a stout 391 seta. The extreme base of the head has some scale-filled punc- tures, but these are concealed until the head has been detached from the body. RortoPERUS BASALIS, n. sp. ¢. Black; antennze and tarsi red. Densely clothed with muddy-brown scales; with numerous fascicles on upper- surface. Head with derm concealed, except on a narrow, bald, basal space. Rostrum lightly curved, rather stout, sides lightly incurved to middle; with concealed sculpture, except on apical two-fifths, which are shining and with small but distinct punctures. Scape short, inserted slightly nearer base than apex of rostrum. Prothorax moderately transverse, base strongly bisinuate, sides moderately rounded; punctures normally concealed; with ten very feeble swellings supporting feeble fascicles. Hlytra with sides moderately rounded, base strongly trisinuate; with rows of large more or less concealed punctures; interstices with feeble swellings, supporting fascicles, of these there are four on the third interstice, three on the fifth, four on the seventh, and one on the suture on the posterior declivity, some smaller ones elsewhere. Under- surface with dense punctures, and with larger and sparser ones, but all more or less concealed before abrasion. Basal segment of abdomen feebly depressed in middle, the second flat. Length, 44-5 mm. Hab.—New South Wales: Mount Kosciusko (H. J. Carter). In general appearance much like the preceding and several other species, but with a fascicle on the suture. Seen from in front the base of the elytra appears to have four con- épicuous, shining, subtriangular processes, these being on the third interstices and shoulders, and due to the tubercles there being glabrous internally. From behind they are much less conspicuous. ROPTOPERUS LONGUS, 0. sp. Black, somewhat shining; head, rostrum, and under- ‘surface more or less distinctly diluted with red; antenne and tarsi paler. Upper-surface with stout sete scattered about, and in places formed into fascicles, these on the posterior por- tion of the elytra are mostly sooty, but elsewhere they are paler. Under-surface and legs with rather dense scales in addition to the sete. Head with coarse punctures in front, then bald and shining. Rostrum wide at base, narrowed to, and parallel- sided in front of antennz; about base with somewhat coarser punctures than on head, elsewhere shining and with minute 392 punctures. Scape short, inserted distinctly nearer base than apex of rostrum. Prothorax quite as long as wide, sides moderately rounded, surface somewhat uneven; with dense, round, clearly-defined punctures. Elytra strongly trisinuate at base, with shoulders clasping prothorax, sides oblique to middle and then subarcuate to apex; with rows of rather shallow punctures; with feeble tubercular swellings support- ing fascicles. Under-surface with punctures normally con- cealed. Two basal segments of abdomen almost flat in middle. Length, 44-43 mm. Hab.—Tasmania: Waratah (A. M. Lea). A very distinct species. The almost entire absence of clothing (other than sete) from the upper-surface is ap- parently natural, as the two typical specimens (whose sex is doubtful) are alike in this respect. The highly-polished space causes the head to look as if a polished cap had been drawn over portion of it. The elytra are so shaped, and the fascicles so placed, as to cause the posterior declivity to appear to commence quite close to the base. On each elytron there is an oblique row of feeble, subconnected, pale fascicles, com- mencing on the third interstice at the basal fourth, and end- ing on the seventh at its middle; from this one there is an oblique row of sooty fascicles, one on the fifth, one on the third, and a very feeble one on suture at about one-fourth from the apex. On the two elytra, therefore, these fascicles appear to mark the sides of a diagonally placed square; but there is also a feeble fascicle on the middle of the third interstice. ROPTOPERUS BRYOPHILUS, N. sp. do. Blackish; head and rostrum of a dingy red; antenne and tarsi paler. Densely clothed with muddy-brown scales, somewhat variegated on elytra; under-surface with paler clothing. Upper-surface with numerous fascicles. Head densely squamose in front, elsewhere bald and shining. Rostrum wide at base, sides narrowed to, and parallel-sided in front of antennze; basal third with coarse concealed sculpture, elsewhere shining and with minute punc- tures. Scape short, inserted somewhat nearer base than apex of rostrum. Prothorax about as long as wide, sides moderately rounded; surface uneven and with normally- concealed punctures. Hlytra not very long, base strongly trisinuate, sides moderately rounded; punctures normally concealed; third, fifth, and seventh interstices with distinct fascicles. Under-surface with large partially-concealed punc- tures. Mesosternal receptacle feebly raised, walls thin and U-shaped, feebly cavernous. Basal segment of abdomen gently depressed in middle, the second flat. Length, 2? mm. 393 @. Differs in having less of the rostrum clothed and two basal segments of abdomen gently convex. Hab.—Tasmania: Waratah, in moss (A. M. Lea). The U-shaped mesosternal receptacle, with thin walls throughout, is at variance with the genus, but as it is not supported by other characters it was considered better to refer the species to Hoptoperus rather than to a new genus. It is the smallest one yet described. On the female there is a feeble pale spot on the middle of each elytron, and a still more feeble medio-lateral one, but on the male these are not traceable. ROPTOPERUS PALLIDICORNIS, n. sp. 6. Blackish; head, rostrum, legs, and under-surface of a more or less dingy-red; antennz almost flavous. Upper- surface with stout sete or scales scattered about, and com- pacted into numerous fascicles. Head largely bald; with coarse punctures in front. Rostrum very wide at base, strongly narrowed to, and parallel-sided in front of antenne; basal third with coarse concealed punctures and a feeble median carina, elsewhere shining and with minute punctures. Scape short, inserted much nearer base than apex of rostrum. Prothorax about as long as wide, sides strongly rounded, disc rather strongly convex; with dense and coarse punctures. Hlytra subcordate, base almost truncate, and narrowly elevated, except at suture and shoulders, sides suddenly and strongly rounded to beyond the middle; with rows of fairly large punctures, in distinct strie; third and fifth interstices with feeble swellings sup- porting fascicles. Basal segment of abdomen distinctly con- cave, with a curved row of large punctures; second segment with large irregular ones in middle, the other segments with small ones. Length, 3 mm. Hab.—Queensland: Little Mulgrave River (H. Hacker). More of the head is bald than in sewtellaris and terre- regine; the bald space is marked off from the base by an impressed line, but until the head is detached from the body this line is concealed. On the upper-surface most of the derm is visible, but not to the same extent as in longus. The abdo- men of the type is almost entirely glabrous, but this may be due to abrasion. The elytra at the extreme base are no wider than the base of the prothorax, ‘but the sides are strongly rounded, so that at their greatest width they are fully once and one-half as wide. ROPTOPERUS TERRZ-REGIN#E, Lea. The base of the elytra of this species is narrowly raised and shining (on the type this was concealed by gum). On 394 abrasion rather wide striz, containing oblong punctures, be- come visible. With the rostrum in its canal (the usual posi- tion of unset Cryptorhynchides) the highly-polished base of head appears as a narrow rim touching the prothorax; with the head set out but still attached to the body the polished space disappears. The female differs from the male in having the two basal segments of abdomen decidedly convex, the rostrum longer and thinner, and with its clothing confined to the basal third. EXITHIUS. The following new species of this genus may, for the sake of convenience, be divided into four groups based on the pre- sence or absence of a scutellum or of femoral teeth. 1. Scutellum distinct, femora dentate. 2. Scutellum indistinct or absent, femora dentate. 3. Scutellum distinct, femora edentate. 4. Scutellum indistinct or absent, femora edentate. The head when at rest has its base quite concealed, but the basal punctures are often of use in distinguishing species. The base is always evenly convex, but it is frequently marked off from the front by a more or less distinct depression, fre- quently with a trisinuate outline. With the head attached to the body but extended in front of the usual “‘set’’ condi- tion, the boundary line of the forehead is concealed under the overlapping prothorax. Group 1. EXITHIUS BASIPENNIS, N. sp. 3. Blackish-brown ; antenne and tarsi reddish. Densely clothed with large soft scales, mostly fawn-coloured, but vary- ing from white to sooty; under-surface, legs, head, and base of rostrum with less variegated scales. Prothorax with six fascicles; elytra with fascicles on third and fifth interstices. Head gently convex; with dense normally-concealed punctures. Rostrum rather wide, sides distinctly incurved to middle; with dense and rather coarse punctures concealed on basal half. Scape inserted about two-fifths from apex of rostrum. Prothoraz lightly transverse; with dense normally- concealed punctures. Scutellum small and transverse, but dis- tinct. Hlytra at base not much wider than prothorax, sides rounded, near apex strongly narrowed ; base with tubercles or large elongated granules, and a few smaller ones on suture; third and fifth interstices with feeble tubercular swellings 395 supporting the fascicles; with large, oblong, but normally- concealed punctures. Metasternal episterna distinct in front, but very narrow behind. Four hind femora rather strongly dentate, the others very feebly so. Length, 43-5 mm. Q. Differs in having the rostrum slightly longer, with smaller punctures, less of the base clothed, and antennz in- serted slightly nearer the middle, and basal segment of abdo- men evenly convex instead of flat in middle. Hab.—Tasmania (Aug. Simson, his No. 3776): Stonor; Frankford, on stumps and fence-tops at night (A. M. Lea). Resembles to a certain extent some of the varieties of conspiciendus, but the scutellum is smaller, shoulders different, and posterior declivity longer. There is a rather large patch of whitish scales at the base of the prothorax, usually very conspicuous, but occasionally traceable with difficulty; it is usually circular in outline, but sometimes is extended forward on each side to meet the median fascicles. There is also an oblique, but seldom distinct, line of white scales from each shoulder. The sutural portion of the posterior declivity is clothed with rather pale scales, enhanced by a subtriangular velvety patch of dark ones on each side about the apex. The prothoracic fascicles are loosely formed and in the usual posi- tions, the elytral ones are more or less elongate, and are seldom distinctly terminated. The tubercles or large granules at the base of the elytra are always distinct, and are sometimes of a rather bright-red, although usually darker. On abrasion the elytral punctures are seen to be quite large, and fully as wide as the interstices, but normally they are almost or quite concealed. EXITHIUS CYCLOTHYREUS, n. sp. g. Black; antenne dull-red. Densely clothed with large, soft, round scales, mostly fawn-coloured, but varying from white to sooty. Head evenly convex; with dense punctures, moderately large in front of antenne, becoming larger towards and con- cealed on basal third. Scape inserted one-third from apex of rostrum. Prothoraz rather strongly transverse, sides strongly rounded; with dense, round, partially-concealed punctures. Scutellum round and distinct. Hlytra at base suddenly but not much wider than prothorax, widest almost in middle, sides thence gently arcuate to apex; with rows of large partially- concealed punctures ; alternate interstices very feebly elevated. Metasternal episterna narrow but distinct throughout. Femora acutely dentate. Length, 4-44 mm. Q. Differs in having the rostrum slightly longer and thinner, with sparser and smaller punctures and less of base clothed ; antennz inserted not quite so ciose to apex, and basal 396 segment of abdomen evenly convex, instead of gently concave in middle. Hab.—Tasmania (Aug. Simson, his No. 3375): Frankford ; Ulverstone; Mount Wellington (A. M. Lea). In appearance fairly close to the typical form of con- spiciendus, but head evenly convex; fwmatus is larger, with less conspicuous scutellum, smaller femoral teeth, and different clothing. The white or whitish scales, which as a rule are larger than the others, cause the surface to appear somewhat greyish. They are nowhere, except on scutellum, in distinct patches, but are rather more numerous across middle of pro- thorax and beyond middle of elytra than elsewhere; they also form feeble femoral rings. The sooty scales usually form several very feeble spots on the posterior declivity. The tarsi are sometimes almost black, and sometimes scarcely darker than the antenne. EXITHIUS TRISINUATUS, n. sp. Black; antenne and tarsi reddish. Densely clothed with sooty scales, on the under-surface and legs feebly variegated with whitish ones; elytra with a conspicuous transverse patch of white scales at summit of posterior declivity; scutellum with ochreous scales. Prothorax with six fascicles, elytra with many. Head with the forehead conspicuously trisinuate; with very dense punctures, concealed in front. Rostrum moder- ately stout, sides moderately incurved to middle; with dense and rather coarse punctures, concealed about base. Scape in- serted in middle of rostrum, scarcely longer than the two fol- lowing joints combined. Prothoraz moderately transverse, sides strongly rounded; with dense normally-concealed punc- tures. Scutellum round and distinct. Hlytra short, sides rather strongly rounded, base trisinuate; with rows of large almost entirely-concealed punctures; alternate interstices with feeble tubercles supporting fascicles; suture with a few granules near base. Mesosternal receptacle rather strongly elevated. Metasternal episterna rather narrow in front, and not continued to apex. Femora strongly dentate; front tibize bent downwards in middle, the others subfalcate. Length, 5 mm. : Hab.—Tasmania (A. M. Lea). In appearance something like a variety of conspiciendus, but femora much more strongly dentate and front tibie different. The conspicuous white patch on the elytra should be very distinctive. As the basal segment of its abdomen is flat in the middle, the type is probably a male. 397 Group 2. EXITHIUS ATHYREUS, Nn. sp. Black ; antenne and tarsi reddish. Densely clothed with large soft scales, mostly fawn-coloured, but largely mixed with black. Prothorax with six fascicles, elytra with many. Head with forehead marked off by a somewhat sinuous depression, the depression interrupted by a short median ridge ; with dense punctures, partially concealed in front. Rostrum moderately stout, sides distinctly incurved to middle, strongly notched on each side of base; behind antennze with large partially-concealed punctures, in front of same with smaller clearly-defined ones, and a few minute ones interspersed. Scape rather stout, inserted almost in middle of rostrum. Prothoraz moderately transverse, sides strongly rounded, apex half the width of middle; with rather large partially-concealed punc- tures; with a short and very feeble median carina or impunc- tate line. Scutellum absent. LHlytra stout, sides irregularly rounded, base trisinuate ; with rows of large, deep punctures, becoming smaller posteriorly and partially concealed in places ; suture with depressed granules on basal half, second to seventh interstices with feeble tubercles supporting distinct fascicles. Metasternal episterna very narrow, but frontal triangle dis- tinct. Basal segment of abdomen flat in middle, each side of base with an irregular impression, its suture with second con- spicuously curved in middle. Femora stout, strongly dentate ; tibie bent downwards in middle. Length, 64-6? mm. Hab.—New South Wales: Blue Mountains (HE. W. Fer- guson). In appearance close to a large variety of fuwmatus, but head depressed near forehead, and base of rostrum more con- spicuously notched on each side (on most specimens of fumatus the notches are either not present or are almost concealed by clothing, and only visible from behind). On the elytra there are several feeble transverse patches of whitish scales; the abdomen is almost entirely clothed with sooty scales, and on the prothorax they are in the majority. On the head the scales are dingy, but feebly variegated. The club is somewhat darker than the rest of the antenne. The suture and the lateral inter- stices are the only ones without fascicles. The two typical specimens are probably males. EXITHIUS INTERMIXTUS, 0. Sp. Blackish; antenne and tarsi reddish. Densely clothed with large soft scales, varying from whitish to sooty. Pro- thorax with six feeble fascicles, elytra with many. Head evenly convex; with very dense punctures, larger 398 and partially concealed in front. Rostrum rather long and thin, sides very feebly incurved to middle, shallowly notched on each side of base; with dense clearly-defined punctures of moderate size, becoming larger towards and partially con- cealed on basal third. Scape inserted about three-sevenths from apex of rostrum. Prothorax rather lightly transverse, sides strongly rounded, apex about half the width of base; with dense, round, partially-concealed punctures; with a feeble impunctate median line. Jlytra robust, sides moderately rounded, base trisinuate; with rows of large, sub- oblong, partially-concealed punctures; second to seventh interstices with feeble tubercles, supporting feeble or moderate fascicles; a few granules about scutellar region. Mescsternal receptacle feebly elevated. Metasternal episterna rather wide. Femora stout, four posterior strongly, the others rather feebly dentate. Length, 74 mm. Hab.—Tasmania: Ulverstone (A. M. Lea). In general appearance rather close to Vechyrus legutimus, but mesosternal receptacle cavernous. In size, and to a cer- tain extent in appearance, fairly close to the preceding species, but with head evenly convex throughout (although with punctures coarser in front than behind) and mesosternal re- ceptacle less elevated in front, with its emargination deeper. The clothing also is more conspicuously variegated. On the prothorax the scales, for a rather wide space along the middle, are mostly sooty, on each side they are mostly fawn-coloured, but with a distinct paler spot close to the dark patch; on the basal half of the elytra they are mostly sooty, on the apical half mostly fawn-coloured, but largely mixed with whitish at summit of posterior declivity. On the abdomen and head they are entirely sooty. As the basal segment of its abdomen is flat in the middle the type is probably a male. EXITHIUS TENEBROSUS, N. sp. Black; antenne and tarsi reddish. Densely clothed with muddy-brown and sooty scales. Prothorax with six very feeble fascicles, elytra with many. Head rather strongly convex; with very dense punctures, concealed between eyes. Rostrum rather short, stout, and strongly curved, sides distinctly incurved to middle, distinctly notched on each side of base; with dense and coarse punc- tures, becoming more regular, but still dense, in front of antenne. Scape stout, inserted in middle of rostrum, about half the length of funicle and club combined. Prothorax rather strongly transverse, sides strongly rounded; with dense partially-concealed punctures; second to seventh interstices with very feeble tubercular swellings, supporting feeble 399 fascicles. Mfesosternal receptacle rather feebly elevated. Metasternal episterna distinct throughout. Basal segment of abdomen flat or feebly depressed in middle. Femora stout, strongly dentate. Length, 54-6 mm. Hab.—New South Wales: Jindabyne (H. J. Carter). In general appearance fairly close to brevis, but larger, rostrum shorter and stouter, and femoral dentition stronger. The teeth on the femora are acute and rather strong; on brevis they are all small, those on the front pair being trace- able with difficulty; fuwmatus is a larger species, with paler clothing and distinct sutural granules. The clothing on the episterna is distinctly ochreous, and, to the naked eye, appears as a conspicuous short line on each, as it is also partly on the sides of the metasternum as well, it causes the episterna to appear wider than they really are. Of the two typical (and probably male) specimens, one has shades of colour of the scales scarcely contrasted, and on the other the shades are not conspicuous to the naked eye, so that the whole insect has a dingy appearance. The convexity of the head is partly due to a short and feeble median ridge. EXITHIUS CONJUNCTUS, 0. sp. Black; antenne and tarsi of a rather bright-red, rostrum and tibiz somewhat darker. Densely clothed with large soft scales, mostly of a rather dingy-fawn colour, but in places sooty. Prothorax with six feeble fascicles, elytra with many. Head depressed and somewhat sinuous in front; the de- pressed portion with coarse partially-concealed punctures, else- where with dense clearly-defined ones. Rostrum moderately wide, sides distinctly incurved to middle, lightly notched on each side of base; basal third with coarse partially-concealed punctures, elsewhere with rather small but clearly-defined ones. Scape inserted two-fifths from apex of rostrum, almost the length of funicle. Prothorax moderately transverse, sides strongly rounded, apex scarcely half the width of middle; punctures normally concealed. JHlytra with sides rather strongly rounded, shoulders prominent, but not as wide as widest part of prothorax, base trisinuate; with rows of large partially-concealed punctures; suture with conjoined tubercles at summit of posterior declivity, fourth tuberculate near apex ; elsewhere with obsolete tubercles, supporting fascicles. Under-surface with punctures entirely concealed. Meta- sternal episterna not traceable throughout. Femora stout, strongly dentate. Length, 3? mm. Hab.—Tasmania: Nubeena (A. M. Lea). A small unusually distinct species with very stout femora. The shoulders are distinctly projecting, although not to the 400 same extent as in musculus, from which species, and from all others of the genus, it may be distinguished by the conjoined fasciculated tubercles on the suture. On the prothorax the scales are sooty on the disc, but with two minute median spots, a small medio-basal spot, and the sides fawn-coloured. On the elytra the sooty scales are mostly confined to a sub- triangular patch commencing on each shoulder and terminated beyond the middle. On the abdomen the scales are unusually dense and erect. As the two basal segments of its abdomen are rather strongly convex, the type is probably a female. EXITHIUS LOCULIFERUS, Nn. sp. $. Black; antenne and tarsi of a rather bright-red, rostrum and tibie darker. Densely clothed with large, soft, sooty scales, conspicuously variegated with more or less ochreous, sometimes whitish, ones. With numerous erect scales scattered about, and in places forming fascicles. Head convex; with dense punctures, concealed in front. Rostrum moderately long, sides distinctly incurved to middle; base and sides near base with coarse partially-concealed punc- tures, elsewhere with dense and small clearly-defined ones. Scape inserted two-fifths from apex of rostrum, not much shorter than funicle. Prothorax twice as wide as long, sides strongly rounded; with dense partially-concealed punctures. Elytra scarcely once and one-half as long as wide, sides moderately rounded, base almost truncate; with rows of large almost-concealed punctures; suture usually with some small shining granules. Mesosternal receptacle strongly elevated. Metasternal episterna narrow and _ indistinct. Femora stout, strongly and acutely dentate; four front tibiz subfaleate. Length, 33-5 mm. Q. Differs in having the rostrum thinner and smoother, with sparser and smaller punctures, antenne inserted not quite so close to apex, and basal segment of abdomen moderately convex, instead of flat in middle. Hab.—Tasmania: Mount Wellington (H. H. D. Griffith) ;° Hobart, Huon River, Launceston, Ulverstone (A. M. Lea). An unusually short robust species, not very close to any previously described one. It has dense erect scales, set amongst the others, and in places compacted into feeble fascicles. On the prothorax there are usually two ochreous spots (each composed of from one to six scales) in middle, and one in middle of base. The ochreous scales may either almost entirely cover the sides, or but a small portion of same. On the elytra there is a conspicuous coffin-shaped patch of ochreous scales on the posterior declivity, its outlines always 401 distinct, but its inner parts usually more or less largely variegated with black; there are also a few ochreous spots about the base, and a small whitish one on the fifth interstice at the basal third. On the under-surface the scales are mostly ochreous, but often variegated with sooty. On the legs they are usually sooty and ochreous, but frequently variegated with white on the femora. The depressed scales on the elytra are comparatively small and closely compacted; on the abdomen and sides of prothorax they are considerably larger and each is distinct. On abrasion the elytral punctures are seen to be very large and wider than the interstices; before abrasion, however, the majority are quite concealed. The femoral dentition is unusually strong and acute. EXITHIUS MEGAPHOLUS, 0. sp. Blackish; antenne and tarsi of a rather bright-red, rostrum and rest of legs somewhat darker. Densely clothed with large soft scales, mostly fawn coloured, but with a few whitish and sooty ones; with numerous stiff erect scales scat- tered about. Head with dense concealed punctures in front. Rostrum moderately wide, sides lightly incurved to middle; base and sides near base with coarse partially-concealed punctures, else- where with dense and small but clearly-defined ones; a feeble impunctate line along middle. Scape inserted one-third from apex of rostrum, almost the length of funicle. Prothorax strongly transverse, sides strongly rounded; punctures nor- mally concealed. Elytra with sides rounded and widest at about basal third, base trisinuate ; with rows of large partially- concealed punctures; suture with a few granules near base. Mesosternal receptacle strongly elevated. Metasternal epis- terna indistinct. Abdomen with basal segment feebly de- pressed in middle, its suture with second almost straight. Femora stout, lightly but acutely dentate. Length, 4 mm. Hab.—Tasmania: Frankford (A. M. Lea). On the prothorax the scales are unusually large and soft, and its fascicles (six in number) are very feebly compacted and indistinct. On the elytra several feeble fascicles are pre- sent, but the erect scales are usually not compacted together, the sooty erect ones are usually placed in very feeble trans- verse series. The head is densely clothed in front, the clothing abruptly ceasing, with a somewhat sinuous outline, at the forehead; this is normally concealed with the head at rest, but on exposure is seen to be densely covered with small punc- tures and fine strige. The femoral teeth are almost concealed by the clothing. 402 EXITHIUS STENOCERUS, 0. sp. Blackish; antenne and tarsi reddish. Moderately densely clothed with dingy-brown scales, becoming sooty in places. Prothorax with six feeble fascicles, the elytra with more. Head with punctures concealed in front. Eyes rather more prominent than usual. Rostrum rather wide, almost parallel-sided ; with dense and coarse punctures, almost con- cealed except at tip, where they are smaller. Antenne thin; scape inserted one-fourth from apex of rostrum, and the length of funicle; club elliptic-ovate. Prothorax moderately transverse, sides strongly rounded; with partially-concealed granules and coarse concealed punctures; with a short and feeble median carina. Elytra rather elongate, sides lightly rounded, base lightly trisinuate; with rows of large, deep, suboblong, partially-concealed punctures; third to eighth interstices with small tubercles, supporting fascicles; suture with a few small granules. Under-surface with dense rough punctures. Jfesosternal receptacle scarcely raised, rather widely U-shaped. Metasternal episterna very narrow, but traceable throughout. Basal segment of abdomen depressed in middle. Femora not very stout, rather lightly dentate. Length, 44 mm. Hab.—King Island (A. M. Lea). At first sight apparently belonging to Roptoperus, but femora feebly dentate and third tarsal joint wider. The meso- sternal receptacle has the base moderately wide and the emar- gination transverse, but is less conspicuously raised, and with a smaller base than is usual in the genus; the antennz also are thinner, and are inserted nearer the apex of rostrum than is usual. The hind femora are partially ringed with white scales, but except for this the clothing is nowhere distinctly variegated. On the type (almost certainly a male) most of the head is concealed under the apex of the prothorax. Group 8. EXITHIUS OCCIDENTALIS, n. sp. Blackish; antennz and tarsi reddish, rostrum somewhat darker. Rather densely clothed with scales varying from almost white to sooty. Head evenly convex ; punctures normally concealed. Eyes larger than usual. Rostrum moderately long, sides lightly incurved to middle; with small and fairly dense punctures in front, becoming larger towards and concealed at base; with an impunctate median line. Scape inserted one-third from apex of rostrum, about as loug as funicle. Prothorax moder- ately transverse, evenly convex, sides strongly rounded, apex more than half the width of middle; with dense partially- 403 concealed punctures. Scutellwm small but distinct. LZlytra elongate-cordate, sides rather strongly rounded, each separ- ately rounded at base; with rows of rather large more or less concealed punctures. -Mesosternal receptacle strongly elevated. Metasternal episterna narrow. Basal segment of abdomen moderately convex. Femora not very stout, edentate. Length, 32 mm. Hab.—Western Australia: Vasse River (A. M. Lea). The edentate femora are as in sculptilis, auchmeresthes, and the following species, all of which, however, are without a distinct scutellum. It is the only species known to occur in Western Australia. The scales are mostly fawn-coloured, the sooty and whitish ones are usually in feeble irregular spots. On the prothorax the scales are larger than elsewhere. There are no distinct fascicles, but the elytra have some sooty scales compacted on a feeble tubercular swelling on the third inter- stice near base, and on the fourth about the middle. Group 4. EXITHIUS TRICARINATUS, N. sp. Black; antenne and tarsi of a rather bright-red. Densely clothed with sooty scales, variegated in places with ochreous. Head with coarse punctures, quite concealed in front. Eyes rather small. Rostrum rather stout, sides lightly in- curved to middle; with dense and coarse punctures, concealed about base; base tricarinate, median carina stronger than the others and continued for a short distance in front of antenne. Scape shorter than usual, inserted slightly nearer base than apex of rostrum, scarcely half the length of funicle and club combined. Prothorax rather feebly transverse, sides moder- ately rounded; with dense more or less concealed punctures ; with a very feeble median carina. Hlytra about once and one- third as wide as long, sides strongly rounded, base rather lightly trisinuate; with rows of large partially-concealed punctures ; alternate interstices feebly elevated, the second feebly elevated and shining at base. Jfesosternal receptacle strongly elevated. Metasternal episterna not continuous throughout. Basal seg- ment of abdomen flat across middle, its suture with second strongly curved in middle and deep at sides. Femora stout, edentate. Length, 34 mm. Hab.—Tasmania: Stanley, from summit of “Nut’’; King Island (A. M. Lea). In general appearance like small specimens of brevis or mamabilis, but femora edentate. On the types the ochreous scales are almost absent from the prothorax, on the elytra there are a few feeble spots scattered about, and a feeble transverse row of same at summit of posterior declivity; there is also a 404 feeble whitish spot on the third interstice at the basal third. On the under-surface the ochreous scales are almost confined to the three apical segments. EXITHIUS BREVIS, Lea. The type of this species was somewhat abraded. Speci- mens in perfect condition have the scales mostly deep-black, more especially those forming the rather numerous fascicles. The species appears to be fairly common on the Blue Moun- tains; and two specimens from that locality have two small white spots on the elytra at the summit of the posterior declivity, one of these having in addition two small median spots. The rostrum is conspicuously notched on each side of the base. Following is a table of the species : — A. Prothorax conspicuously dilated in front... cariosus AA. Prothorax not so dilated. B.

Antenne rather thin, inserted nearer apex than base of rostrum; two basal joints of funicle elongate; club ovate. Prothorax trans- verse, sides rounded, apex produced. Scutellwm small or absent. Hlytra subovate, base trisinuate. Pectoral canal deep and moderately wide, terminated between middle coxe. Meso- sternal receptacle with narrow U-shaped walls; slightly cavernous. Metasternum very short, but episterna traceable throughout. Abdomen large, intercoxal process wide, two basal segments large, the suture between them incurved to middle. Legs rather thin but not very long; femora neither grooved nor dentate, hind pair not extending to apical seg- ment; tibie straight, except at extreme base. Densely squamose, fasciculate, apterous. The genus is rather close to Haithius, but distinguished therefrom by the thin and U-shaped mesosternal receptacle, metasternal episterna traceable throughout, convex forehead and femora neither grooved nor dentate. The mesosternal receptacle is almost open, but as the wall at its extreme base slightly overlaps the canal it must be regarded as cavernous. The three known epee are all Tasmanian.

Black; antenne and tarsi reddish. Densely clothed with muddy-grey scales; with some darker, stout, erect ones scattered about, and in places condensed into fascicles. Under-surface setose. Head with very dense concealed punctures. Rostrum fully the length of prothorax, sides lightly incurved to middle, base wider than apex; basal two-thirds with coarse concealed punctures, apical third with smaller and mostly-exposed ones. Prothorax moderately transverse, sides strongly rounded, apex more than half the width of base ; with dense, round, concealed punctures. Scutellum not traceable. EHlytra ovate-cordate, sides gently rounded; with rows of large and usually some- what angular, but normally almost concealed, punctures ; with a few small granules (sometimes concealed) on suture near base. Under-surface with dense setiferous punctures, larger on metasternum than elsewhere, and forming a single row across each of the third and fourth abdominal segments. Length, 4-54 mm. Differs in having the rostrum distinctly longer and thinner, basal fifth only with concealed punctures, the surface 407 elsewhere shining and with small clearly-defined ones ; antennze inserted just in advance of middle, instead of at apical two- fifths; abdomen more convex, and legs somewhat shorter. Hab.—Tasmania: Mount Wellington (H. H. D. Griffith and A. M. Lea); Hobart (L. Rodway). The fascicles on some specimens are but little darker than the surrounding scales, but on others are almost sooty. There are six on the prothorax: four across middle and two at apex, but some of these occasionally disappear. On the elytra they are confined to the odd interstices, and are usually very feeble, except for four fairly distinct ones near the base. Several specimens have the clothing mostly of a muddy-brown, instead of a muddy-grey, and some others have the scales on the pos- terior declivity (except at the sides) distinctly paler (almost white) than the others. Numerous specimens were taken under bark of living trees and in crevices of dead ones. TAPINOCIS SCUTELLARIS, Nn. sp. 3. Black or blackish; antenne and tarsi reddish. Densely clothed with muddy-grey scales, sometimes obscurely variegated with muddy-brown; with some stout scales scat- tered about, and in places condensed into fascicles. Under- surface with rather stout sete. Legs densely clothed, and sometimes obscurely ringed. Head with very dense and usually concealed punctures. Rostrum about the length of prothorax, sides distinctly in- curved to middle; with coarse crowded punctures, except on a short, shining, median line, but partially concealed on basal half. Prothorax moderately transverse, sides on basal half feebly rounded, apex more than half the width of middle ; with dense concealed punctures and with a short and feeble median carina. Scutellum small, but elevated.and distinct. Elytra slightly dilated from base to beyond the middle, thence coarc- tate to apex ; with rows of large partially-concealed punctures, becoming smaller posteriorly; interstices with tubercular swellings, supporting fascicles, a granule on each side of base close to. scutellum. Under-surface with rather dense setiferous punctures. Metasternum somewhat shorter than in the pre- ceding species, and with smaller punctures. Length, 43-5 mm. Q. Differs in having the rostrum somewhat longer and thinner, shining, with smaller and sparser punctures, con- cealed only at basal fourth; antennz inserted slightly nearer the middle of rostrum, and abdomen more convex. Hab. — Tasmania: Mount Wellington (H. H. D. Griffith) ; Launceston (Aug. Simson, his 3208). The prothorax has larger and more rounded scales than elsewhere, its fascicles are rather loosely compacted and six in 408 number. On the elytra there are fairly numerous fascicles, mostly on the odd interstices, the most distinct of all is on the third, crowning the posterior declivity. TAPINOCIS SUBAPICALIS, D. Sp. Blackish; antennez and tarsi reddish. Rather densely clothed with somewhat variegated scales, and with numerous fascicles. Under-surface moderately clothed. Head with dense concealed punctures. Rostrum slightly longer than prothorax, sides moderately incurved to middle ; basal fourth with concealed punctures, elsewhere shining and with small but clearly-defined ones, larger on sides than along middle. Prothoraz rather lightly transverse, sides strongly rounded, apex more than half the greatest width; with dense more or less concealed punctures; with a short and feeble median line. Scutellum not traceable. Hlytra moderately dilated to beyond the middle; with rows of large partially- concealed punctures; with tubercles supporting fascicles. Under-surface much as in preceding species. Length, 5 mm. Hab.—Tasmania (J. E. Philp). In build somewhat resembling the preceding species, but the scutellum not traceable, and without the two small tubercles or granules near the same. The type is evidently in perfect condition, and is probably a female. Its clothing is mostly of a chocolate-brown, varied in places with muddy-brown or muddy-grey, and with a distinct curved line of pale scales on each side of the posterior declivity near apex. It is probable, however, that, as with the two preceding species, the clothing is subject to considerable variation. On the prothorax there are six fascicles in the usual positions. On each elytron there is a large fascicle crowning the posterior declivity, and rather numerous ones elsewhere, but mostly on the third (on which the large one is placed), fifth, and seventh interstices. TENTEGIA CYCLOPTERA, Nn. sp. Black; antenne and tarsi of a dingy-red. Sparsely clothed with brownish scales, but becoming dense on legs. Each granule with a stout and usually curved seta. Head with large coarse punctures in front, elsewhere with dense small ones. Rostrum stout, lightly curved, sides gently incurved to middle; punctures as on front of head, but at apex crowded and smaller. Scape inserted in middle of rostrum, about half the length of funicle and club combined. Prothorax strongly convex, moderately transverse, sides strongly rounded; with numerous large granules or small tubercles, regularly disposed, but smaller at apex than else- where. Jlytra not much longer than wide, sides strongly 409 rounded, base truncate, apex rather narrow; with rows of large punctures, alternating with rows of large granules. Under-surface with coarse punctures, except on third and fourth segments of abdomen. Legs long; femora edentate, the hind ones passing apex of elytra; tibiz ridged on each side. Length, 54 mm. Hab.—Torres Straits: Banks Island (H. Elgner). In general appearance close to anopla, but sides of elytra not clasping prothorax at base, and punctures of under- surface, although large, less sharply defined, rostrum stouter and with punctures not in regular series. From quadriseriata, which has the base of elytra very similar, it is distinguished by its rostral punctures and edentate femora. Although the punctures on the rostrum are not in four distinct rows, they have, nevertheless, a tendency to a linear arrangement. The elytral punctures are so placed that each is bounded by four granules, and the granules so that each is bounded by four punctures. IMALIODES OOPTERUS, N. sp. g. Black; antennz and tarsi reddish ; with rusty-brown scales, rather dense on under-surface and legs, sparser on upper-surface. Head with dense partially-concealed punctures. Eyes rather small and prominent, facets rather coarse. Rostrum moderately long, not very thin, sides distinctly incurved to middle; punctures dense on apical fourth, but elsewhere con- cealed. Scape inserted almost in exact middle of rostrum, the length of three following joints combined; second joint of funicle about twice the length of first. Prothorax about as long as wide, sides strongly rounded, apex almost as wide as base; with large and usually clearly-defined punctures. Scutellum absent. Llytra elliptic-ovate, strongly convex, each separately feebly rounded at base, shoulders not produced, sides rather strongly and evenly rounded; with rows of large punctures, becoming smaller posteriorly; third interstice with a distinct tubercle near base, the second with several feeble swellings. Third and fourth segments of abdomen slightly depressed below level of fifth and distinctly below level of second. JZegs rather long and thin; femora feebly grooved, edentate, hind pair passing apex of elytra. Length, 7 mm. Hab.—Queensland: Mulgrave River (H. Hacker, his Nos. 1148 and 1155). The edentate femora and long second joint of funicle associate this species with edentatus, from which it differs in 410 being larger, with longer legs, less densely clothed, punctures more clearly defined, and by the base of elytra. At a glance it looks very close to Anchithyrus caliginosus, but (apart from several generic distinctions) that species has the two basal joints of funicle subequal in length. On the prothorax there are three feeble median swellings moderately densely clothed, but they are not very distinct. The tubercle on the third. interstice of each elytron of the type is connected by a slight ridge with its fellow across the suture, and with the base by a still more feeble ridge; between the ridges the punctures are much smaller than the adjoining ones. This peculiar structure is evidently not an accidental variation, as it is the same on some specimens that were in Mr. Hacker’s private collection, now in the Berlin Museum. IMALIODES VENTRALIS, Nh. Sp. 6. Black; antennze and tarsi obscurely diluted with red. Densely clothed with ashen-grey scales, denser on legs and paler on shoulders than elsewhere. Head rather convex; punctures concealed. Hyes rather small and with rather fine facets. Rostrum moderately long, not very thin, sides lightly incurved to middle, punctures concealed, except at tip, where they are dense. Scape inserted slightly nearer apex than base of rostrum, about half the length of funicle and club combined; two basal joints of funicle rather long and thin, subequal in length. Prothoraz rather convex, moderately transverse, sides strongly rounded. Scutellum absent. Llytra elliptic-ovate, strongly convex, base almost truncate, but shoulders feebly and obtusely produced, sides strongly rounded; with rows of large punctures, be- coming smaller posteriorly; with numerous small tubercular swellings. MJesosternal receptacle strongly elevated.
