RITSEMA Cz. 1. Clinteria Hageni, n. sp. Length 12 mm. — Velvety and of a dull brownish- green colour above , shining with coppery and brassy tinges beneath, the pygidium dull reddish- brown , opaque. Face and clypeus closely punctate , the latter quadrate , the front margin straight, its upturned edge however faintly emar- ginate in the middle, the lateral angles broadly rounded. Thorax covered with fine punctures which are rather uni- formly spread over the whole surface, and provided with six minute white dots arranged in two transverse rows of which the anterior one consists of two , the posterior cur- ved one of four dots ; three by three these dots form two lateral triangles which have their tip directed to the centre of the disk. Scutellum very small, narrow and acute. Elytra slightly narrowing towards the apex , faintly punc- tate-striate , the internal striae not continued on the basal half, the sutural angles rounded. Each elytron provided with two marginal and two discal spots of a pale orange- yellow colour, viz: a rather large squarish marginal spot just behind the middle , a small marginal spot in the outer apical angle , a small discal spot nearly touching the ante- rior angle of the large marginal spot , and a very minute Notes from the Leyden ÜMuseutxi, Vol. VI. 1 A CLINTERIA HAGENI. clot ou the middle of the apical half at some distance from the suture. Pygidium transversely scratched , sparingly covered with short pale bristles , and provided with a small vrhite spot at each side. Under surface and legs strongly punctured and sparingly covered with short pale bristles; mesosternal process short, conical; three small white dots on the sides of the mesosternum , and two rows of simi- lar spots on each side of the abdomen. Anterior tibiae with two acute lateral teeth of which the median one is less developed than the ante-apical one. I have much pleasure in dedicating this pretty species to Dr. B. Hagen , who has captured the described speci- men at Tandjong Morawa in the district of Serdang (East Sumatra). According to a communication of Mr. J. W. van Lans- berge who has seen my specimen , this species is closely allied to Clinteria moerens G. & P. of Ceylon; it is repre- sented in his own collection by specimens from Java which show however some slight differences. 2. Glycyphana venusta^ n. sp. Length 11 mm. — Black; above velvety, head and under surface of the body with the legs shining. Head , the clypeus included , strongly punctured , the latter emar- ginate at the front margin , the lobes broadly rounded ; the vertex of the head provided with two small white spots. The anterior half of the thorax densely covered with fine punctures , on the basal region the punctures are wide apart; the basal angles of the thorax red-margi- ned , and the disk at some distance from the front margin provided with two white points. Scutellum rather broadly triangular (as in the allied Swainsonii G. & P.) , not elon- gate triangular (as in Macquartii G. & P. , sumatrensis Voll. and rugipennis Rits.). Elytra with three or four ab- breviated striae parallel to the suture, beyond punctate, the punctures arranged in rather regular longitudinal rows ; JSJotes from the Leyden IMuseum, "Vol. VI. GLYCYPHANA A'ENUSTA. 3 the apical margin of the elytra very minutely serrate or crenulate ; the sutural angles rounded ; just beyond the middle is a transverse band formed of four white trans- verse spots of which the lateral ones are larger than the central ones ; midway between the latter and the apex a white point is present on each elytron. Pygidium opaque, immaculate , covered with short pale bristles and concen- trical scratches; the centre is slightly raised. Under sur- face and legs shining , strongly punctured , and sparingly covered with short pale bristles; mesosternal process short and broad, dilated at the end (as in Swainsonii, but less prominent); epipleura with a small white spot, coxae of hind legs white , hindmargins of the abdominal segments (with the exception of the two apical ones) white-border- ed on the sides ; anterior tibiae with one distinct lateral tooth close to the end and an indistinct one about the middle. A single specimen of this handsome species has been sent over from Tandjong Morawa in the district of Ser- dang (East Sumatra) by Dr. B. Hagen , but I have been informed by Mr. van Lansberge that it is represented in his collection by specimens from Malacca and from Java. 3. Glycyphana saleyeri, n. sp. Length 10.5 — 11.5 mm. — Dull green, with the head black and the pygidium ferrugineous. Above velvety with the exception of the head and pygidium ; the head densely punctured, the front margin emarginate, the lobes broadly rounded ; in five of my eight examples the vertex is* pro- vided with two small white dots. Thorax obscurely punc- tate , with a narrow lateral border (which is a little broad- er at the front margin) and two or four discal points (in five of my eight examples there is moreover a pair of marginal points) white; the most constant of these points are those placed across the middle of the disk. Elytra obscurely punctate-striate , without the slightest trace of Notes from tlie Leyden Mluseum, Vol. VI, 4 GLYCYPHANA SALEYERI. spiue at the sutural angle; each elytron provided with seven or eight white markings: on the basal half', two more or less elongate spots (which sometimes form a lon- gitudinal stripe) on the middle of the disk, and a small point (absent in one of my eight specimens) at the mar- gin of the notch beyond the shoulder; on the apical half, three spots parallel to the suture (the apical one in one of my specimens very small), and two transverse ones touching the lateral margin. Pygidium ferrugineous , con- vex , finely and irregularly scratched in a transverse direc- tion and covered with extremely short pale bristles ; a trace of a longitudinal median keel may be observed ; in four of my specimens the pygidium is immaculate (cf?), in the remaining four it is provided at each side with a strongly curved yellowish patch (Q?). Under surface and legs shi- ning , covered with bristly punctures ; raesosternal process short and broad, dilated at the end, and not protruding. In those specimens which have the pygidium spotted with yellow the sides of the sternum (the epimera included) and abdomen are covered with a yellowish crust , with the exception however of the fourth and apical segment which show only a rather small rotundate spot. In those speci- mens however which have the pygidium immaculate the yellowish crust is confined to the extreme sides of the sternum (the epimera and epipleura included) , and of the hind coxae , and to the hind margin (in connection with the apical angle) of the three basal segments of the abdo- men. Anterior tibiae with one sharp lateral tooth close to the end. Var. Pronotum and elytra black , basal margin of the former faintly rufous (the largest of my specimens). Of this species, which is closely allied to Gl. glauca Blanch., aromatica Wall., labecula Wall. ') etc., eight spe- 1) Mr. van Lansberge regards my species as being identical with labecula Wall.; the latter however has the suture spined, the pronotum not bordered with white laterally, and the pygidium blank. ^otes from the Leyden IMiiseutn , "Vol. VI. PROTAETIA ENGELHARDI. O cimens (the variety included) have been brought home from Saleyer (an island south of Celebes) by Mr. H. E. D. Engelbard, who kindly presented them to the Leyden Museum. The specimens were captured in November, Ja- nuary and March. 4. Protaetia Engelhardi^ n. sp. Length 14 mm. — Shining; green with coppery and purplish tinges above , purplish copper beneath , legs and antennae coppery red. Head and clypeus strongly punctu- red , the fcfi-mer shallowly depressed between the eyes , the depression rather closely set with whitish hairs and pro- vided with a short smooth keel ; the margins of the clypeus are turned up especially the front margin which is biden- tate in consequence of a deep notch in the middle ; the flagellum of the antennae elongate. Thorax rather remo- tely covered with strong deep punctures; the lateral edges are margined and narrowly bordered with white ; moreover the disk shows six minute white spots arranged in two transverse rows of which the anterior one consists of two , the posterior curved one of four spots ; three by three these spots form two lateral triangles the tips of which are direct- ed to the centre of the disk. The scutellum is somewhat elongate triangular, smooth. The elytra are irregularly spotted with white all over, and irregularly and rather densely covered with large but not deeply impressed semi- circular punctures, each of which has a fine central point; the sutural margins which are sharply keeled towards the apex , and a curved ridge extending from the apical cal- lus not quite up to the shoulders are impunctate ; the su- tural angles slightly prolonged. The pygidium shows short curved scratches , and is covered with a white crust which only leaves a bare patch in the middle as well as traces of two lateral ones. Beneath , the hind coxae and the sides of the thorax striate, those of the abdomen sparingly punctured ; provided on the sides with patches of a white Notes from the Leyden Museum, "Vol. "VI. b PROTAETIA ENGELHARDI. crust, which on the abdomen form two lateral rows at each side; a small white spot is moreover preseut at the end of the outside of the posterior femora; the mesoster- nal process is dilated and broadly rounded at the end , and almost inconspicuously prominent; anterior tibiae with a rather indistinct lateral tooth. The described specimen , which is now in the Leyden Museum , has been brought home from Saleyer by Mr. H. E. D. Engelhard to whom I dedicate the species. The specimen was captured in November.

Stethomela marginata^ n. sp. Oblong , subquadrate , testaceous. Apical joints of the antennae and the abdomen, black. Elytra strongly punc- tate-striate , dark violaceous, the extreme lateral margin testaceous. — Length 4 lines. Head impunctate, shining, testaceous. Antennae slen- der, filiform, two thirds the length of the body, the third joint the longest, 5 lower joints testaceous below, the rest black. Thorax transverse, anterior margin semicircu- lar, posterior one sinuate at each side and accompanied by a row of deep punctures , sides straight at the base , rounded towards the apex, surface entirely impunctate, testaceous, obscurely stained with longitudinal fuscous mark- ings. Scutellum testaceous. Elytra distinctly punctate- striate , the apex impunctate , shoulders bounded within by a longitudinal groove. The extreme basal and lateral margin testaceous, this colour gradually narrowed towards the posterior portion of the elytral margin. Legs and breast testaceous. Abdomen black. Claws simple. Hab. Aru Islands (v. Rosenberg). Notes from the Ley den Mitiseum, Vol. "VI. 8 AUSTRALICA UNICOLOR. 2. Australica unicolor , n. sp. Elongate, entirely pale flavous. Head and thorax minu- tely punctured. Elytra finely punctate-striate. — Length 2\—^ lines. Head very finely and closely punctured. Apex of the jaws black. Antennae flavous , extending to the base of the thorax, the latter exceedingly finely and rather spa- ringly punctured at the disk , a little more strongly punct- ured at the sides. Elytra with ten rows of finely punct- ured striae, the interstices very minutely punctured. En- tire underside and legs flavous. Hab. Timor (Wienecke). The present species of Australica is the first described from the Malayan group of Islands, all the others being peculiar to Australia. The nearest allied species are A. pallida Baly and A. geniculata Baly , from both of which the present insect (of which four specimens are before me) differs by its smaller size , and the fine punctuation of its head and thorax. The colour of the antennae and the legs also differs from the allied species. London, October 30th, 1883. Notes from tlie Leyden Museum, "Vol. VI. LEMA SEPARATA. NOTE III.

Underside and legs black , covered with fine greyish pubescence. District of Rawas (Sumatra-Expedition). — Two speci- mens of the variety. This species which I also possess from Borneo seems closely allied to L. pramsta Fabr. and L. terminata Lac. , from both of which it is separated by its black underside and legs and the want of the anterior transverse groove of the thorax. Lema Wallacei, n. sp. Black below. Above dark metallic blue. Elytra deeply transversely depressed , strongly punctate-striate. — Length 12/3 line. Var. a. Entirely black. Var. b.

Antennae of half the length of the body, filiform, third and fourth joints equal , black. Thorax not longer than broad , the basilar groove distinct and rather shallow, surface with a few very fine punctu- res. Scutellum oblong, rounded. Elytra deeply transversely depressed below the base, each elytron with ten regular rows of very distinct punctures visible to the apex , the interstice between the 8th and 9th row wider than the others. Legs rather slender. Underside covered with fine greyish pubescence. Soepajang and Mesauw (Sumatra-Expedition). — Two specimens of the typical form. The small size of this species in connection with its colouration will distinguish it from those found in the r^otes I'rom the Leyclen IVIuseuin, Vol. VI. LEMA WALLACEI. 11 Malayan Archipelago. L. cyanea Lac. and L. atro-coerulea Clark seem nearly allied forms ; fi*om tlie first L. Wallacei may be separated by the want of the anterior thoracic groove and from either by its much smaller size. AspidolopJia ornata , n. sp. Oblong , parallel , fulvous ; below closely pubescent. Ter- minal joints of antennae black. Head and elytra metal- lic greenish blue , the latter closely punctured , a trans- verse spot at the basal margin , an obscure narrow band before the middle and a small triangular spot near the apex of each elytron , fulvous. — Length 3 lines. Head very closely and finely punctured , the sides finely strigose and subopaque ; epistome more shining , transverse , finely punctured , its sides flavous. Labrum piceous. First joint of the antennae incrassate , flavous , second and third joints very small , of nearly the same length , fourth joint elongate, as long as the two preceediug joints together, rest of the joints transverse, extending to the base of the thorax. The latter transversely convex , the posterior mar- gin sinuate at each side , the medial lobe very slightly produced and nearly straight; sides slightly rounded as well as the posterior angles ; surface extremely finely punct- ured at the disk, more distinctly at the sides and near the posterior angles , entirely fulvous. Scutellum strongly elevated, broadly triangular, obscure fulvous with a metal- lic bluish gloss. Elytra moderately convex, not widened behind , distinctly lobed at the shoulders , very closely and irregularly punctate with indications of longitudinal smooth narrow lines , the interstices finely rugose at the sides, of a metallic greenish blue colour, interrupted by a pale fulvous transverse spot placed at the basal margin near the scutellum, a somewhat darker narrow stripe of which the ends only are distinct in shape of a fulvous Notes trom the Ley den Miuseiim, "Vol. VI, 12 ASPIDOLOPHA ORNATA. spot, is situated before the middle, but does not extend to the sutural or lateral margin; another small triangular spot is visible near the apex. Underside closely covered with fine silken whitish pubescence. Posterior first tarsal joint as long as the two following ones united. District of Rawas (Sumatra-Expedition). — A single specimen. Larger than A. Buqueti Lac, of different colour and more finely punctured. Cftfptocephftlinae. Melixanthus bimaculicoUis , Baly. Of this species a single specimen , which is captured in December at Bedar Alam, is contained in the collection. Mr. Baly, on account of the want of the antennae in his specimen , was in doubt whether the insect belonged to this genus. In the specimen before me the antennae are complete and with the exception of the first 3 joints which are fulvous, of a black colour; they extend as far as the base of the thorax, the terminal joints being short and thickened, agreeing therefore with the other species of the present genus. In the specimen from Sumatra the femora are also black, the extreme base only being fulvous; in other respects the insect agrees perfectly with the type. Melixanthus sumatrensis , n. sp. Fulvous. Head and antennae black. Thorax impunc- tate. Elytra black, a transverse band at the middle, ab- breviated at the suture, bright yellow. — Length P/^ line. Head deeply inserted in the thorax , blackish piceous , depressed between the eyes and finely punctured. Labrum flavous. Antennae extending to one third the length of the elytra , entirely black , third and fourth joints of equal length, the rest slightly thickened and shorter. Thorax Notes from tlie Leydea Museum, "Vol. "VI. MELIXANTHUS SUMATRENSTS. 13 subcylindrical , very convex, the sides greatly deflexed , the lateral margins very slightly rounded , surface entirely im- puuctate, fulvous, very shining. Scutellum trigonate, ob- scure fulvous, foveolate at the base. Elytra finely and regularly punctate-striate , black with a transverse yellow band at the middle, interrupted at the suture where it is obliquely cut; the posterior margin of this band is con- cave. Underside and legs entirely fulvous , the last abdo- minal segment with a deep transverse fovea. District of Rawas (Sumatra-Expedition). — A single specimen. Easily distinguished from M. himacuUcolUs by the want of the spots at the thorax, the colour of the underside and legs , and by the longer antennae. Eutno tpinue. Nodostoma hrevicollis , n. sp. Ovate , pale fulvous , shining. Head and thorax im- punctate , the latter very short and transverse. Elytra with basal depression ^ very finely punctate-striate. — Length l^/g line. Head rather convex, entirely impunctate. Epistome forming a single piece with the front , without any punctures , its sides limited by a deep groove. Eyes distinctly notched. Antennae more than half the length of the body, entirely fulvous, slender, the 6 apical joints shorter and slightly thickened. Thorax very short, three times as broad as long, the sides oblique, straight and much narrowed anteriorly, very obsoletely angulate near the base , surface entirely impunctate. Scutellum subquadrate. Elytra ovate, scarcely wider at the base than the thorax , with a distinct transverse basal depres- sion, the space in front of the latter distinctly, below it, very finely punctate, the punctures scarcely visible Notes from the Leyden Miuseum, Vol. VI. 14 NODOSTOMA BREVICOLLIS. below the middle; a row of deep punctures runs close to the lateral margin. Femora unarmed. Two specimens from Soeroelangoen (Sumatra-Expedition). From similarly coloured species , the present one may be separated by the entirely impunctate head and thorax and the very short shape of the latter, also by its ovate general , not elongate shape. Nodostoma ameipennis , Baly. I refer the nine specimens contained in the collection to Mr. Baly's species on account of the peculiarly shaped thorax , which is very wide at the base , angulate close to the latter and obliquely narrowed towards the front, this character as well as the others agreeing with the author's description. The following varieties are however to be noticed: var. a. Thorax greenish black, elytra metallic green. var. h. Underside and legs piceous , head fulvous , other- wise like var. a. var. c. Elytra violaceous blue , finely margined with metallic green , otherwise normally coloured. var. d. Underside piceous , elytra metallic cupreous , otherwise like var. a. In spite of the great variability of this insect , the pecu- liar shape of the thorax and the close punctuation of the latter at the sides will help to distinguish it. The length also varies from l^/g to 2^/4 lines. The specimens are captured at Doesoen Tengah , in the District of Rawas and at Koetoer (Sumatra-Expedition). Nodostoma javanensis , Baly. Of this insect which may be distinguished from the many species forming the genus Nodostoma a typical form Notes from tlie Ley den ]M!useum, "Vol. "VI. NODOSTOMA JAVANENSIS. 16 is contaiued in the Leyden collection as well as two others upon which I look as varieties , as they difier only in size and colour. They are somewhat larger aud the dark colour of the elytra is of less intensity , the base being obscure fulvous as well as the apex , the other specimen being entirely of the latter colour , but I cannot find any other structural characters to justify me in considering these specimens specifically distinct. The specimens are from Moeara Laboe and Loeboe Gedang (Sumatra-Expedition). Nodostoma cuneomicans , Baly. If I am right in referring the numerous specimens before me to this species , with which it agrees , according to the description, in every way, the construction of a new genus is clearly necessary for its reception , as the anterior mar- gin of the thoracic episternum is not concave but very convex. I think that several species at present placed in Nodostoma have this latter character and require the erec- tion of a new genus. The specimens in this collection are captured at Solok , Moeara Laboe , in the District of Rawas , at Palembang , Koetoer and Mesauw (Sumatra-Expedition). Ahirus Jiavopilosus , n. sp. Elongate , subcylindrical , narrowed behind , obscure ae- neous , densely covered with yellowish pubescence. Anten- nae, tibiae and tarsi fulvous. Head and thorax closely punctured. Elytra transversely strigose , obsoletely costate near the apex. — Length 4 lines. Head closely rugose-punctate, covered closely with yel- lowish short pubescence. Clypeus broadly triangular, sepa- rated from the face by a fine groove , punctured like the head. Labrum and palpi fulvous.

Thorax broader than long , subcylindrical , the sides slightly but regularly rounded, the anterior angles acute and pro- duced, surface very closely rugose- p unctate , covered like the head with short golden yellow hairs. Scutellum broadly ovate, finely punctured, glabrous. Elytra closely transversely rugulose and wrinkled , the interstices only punctured near the base and close to the suture , longitu- dinally costate near the apex only , pubescent like the thorax, the hairs short, stiff and of a shining yellow co- lour. Underside and legs still more densely pubescent. Two specimens from Moeara Laboe (Sumatra-Expedition). Closely allied to A. puberulus Lefèv. but differing in the colour of the antennae and tibiae and in the yellow not white pubescence. The head also in the present insect is devoid of any smooth space and tubercle. Abirus violaceus ^ n. sp. Elongate, subcylindrical, bluish black below, finely pu- bescent. A-bove violaceous blue, shining. Sides of thorax obsoletely angulate , surface deeply punctured. Elytra trans- versely elevate-reticulate , punctate-striate near the suture. — Length 4 lines. Head finely and closely punctured , with an obsolete tubercle at the middle of the front. Antennae with the last five joints moderately dilated, bluish, pubescent, the basal joints blackish and shining. Thorax twice as broad as long , the sides but slightly deflexed , lateral margin very obsoletely biangulate , all the angles acute and pro- duced; surface with an oblique depression at each side near the base , closely and deeply punctured posteriorly , the punctuation rather more finely anteriorly , the punct- ures themselves of somewhat oblong shape.

Antennae two thirds the length of the body, pale fulvous , the last 2 or sometimes 3 joints fuscous ; third and fourth joints of equal length. Thorax transverse , the sides very rounded , much deflexed at the anterior portion impunctate; surface remotely impressed Avith rather fine punctures Avhich are irregularly distributed over the disk. Scutellum broadly ovate. Elyira very convex without any basal depression , very regularly punctate-striate, the punct- ures arranged in single lines and more deeply impressed at the sides; interstices slightly costate at the apex only. Underside metallic greenish , sides of the abdomen and the femora stained with piceous or dark fulvous. Tibiae en- tirely of that colour without metallic gloss. Posterior fe- mora armed with a stout tooth , anterior ones with a small one. District of Rawas (Sumatra-Expedition). Notes from the Lejnlen Musevim , Vol. "VI. 2 18 COLASPOiniïS GLABRATA. I separate tb is species from C. varians Baly, to which it seems closely allied , on account of the following diffe- rences : The head is very finely punctured, the epistome is distinctly separated from the face ; the thorax is very irre- gularly punctured at the disk only, the sides being im- punctate. Lastly the elytra show no trace of a basal de- pression nor of costa at the sides. Of the five specimens before me , 3 are distinctly stained with reddish cupreous at the sides of the elytra and at the base of the thorax , and in the male insect the punct- uation of the former is arranged in double rows near the suture. In all other respects the specimens agree with each other. Colaspoides nigripes ^ n. sp. Oblong , convex , black or piceous below. Above greenish cupreous. First 5 joints of the antennae fulvous.

COLASPOIDES NIGRIPES. 19 and deeply punctured at the outer disk where the inter- stices form strongly raised transverse rugosities , which ex- tend through the entire length of the elytra ; the apical portion shows some longitudinal costae near the suture. Legs unarmed. Eight specimens were captured at Paja Koemboeh, Solok and Rengkiang Loeloes (Sumatra-Expedition). From similarly sculptured species , the present one is at once distinguished by the black underside and legs. Colaspoides apicicornis^ n. sp. Broadly oblong.

Scutellum broadly ovate. Elytra strongly punctate-striate , the punctures arranged in distinct double rows towards the suture where they are rather finely impressed , towards the sides they are much larger and more strongly marked; the interstices at the same Notes from tlie Leyden IMuseum, Vol. "VI. 20 COLASPOIDES APICICORNTS. place are transversely rugose and longitutliually costate, 3 or 4 costae being generally plainly visible ; at the apex the costae are shorter and less distinct. Underside dark fulvous , with a metallic green gloss especially at the breast. Legs fulvous , the femora sometimes metallic greenish , the anterior with a small , the posterior ones with a very stout and rather large tooth. Five specimens of this species have been collected by Mr. I. C. van Hasselt at Soekadana: Lampongs. This species cannot be confounded with C. regularis Baly, with which it agrees in the toothed femora, but differs in its smaller size , the colour of the legs and the geminate not singly punctate-striate elytra. Colaspoides ni(jrlcorms , n. sp. Elongate, convex, narrowed behind. Metallic green. An- tennae black, basal joint metallic green. Head closely and strongly, thorax finely and distantly punctured.

Colaspoides sumatrensis , n. sp. Oblong-ovate, convex, entirely fulvous. Two apical joints of the antennae obscure fuscous. Thorax closely and finely punctured. Elytra more strongly punctate-striate , the inter- stices flat. Femora without teeth, — Length l^/g — 1^'4 line. Head impunctate. Epistome not separated from the face at its apex which is narrowed and rather elongate, caused by the depressions at each side , limiting the encarpae ; surface impressed with a few fine punctures. Antennae three-fourth the length of the body, the terminal joints slightly thickened , all the joints with the exception of the second, of nearly equal length. Thorax transverse, nearly three times as broad as long, the sides regularly rounded and not much deflexed in front, surface closely impressed with fine oblong punctures. Elytra without any basal de- pression , closely and rather strongly punctate-striate at their anterior two-thirds , more remotely . punctured near the apex , the interstices not costate but very slightly wrinkled near the sides. Three specimens from Silago (Sumatra-Expedition). I separate this species from C. parvula Baly , to which it seems closely allied , on account of the close punctuation of the thorax and that of the elytra which in the allied species are described as »foveolate-punctate".

Colasposoma. nic/riventre , Baly. If I am right in referring the numerous specimens of different localities contained in the present collection , to Mr. Baly's species on account of the black abtlomen , the insect is a most variable one in regard to size and colour which latter varies from metallic green to bright aureous or cupreous. Some varieties are aureous with the suture and a spot below the base blue , other are entirely of the latter colour. Some of the other species described by Mr. Baly may be but varieties of one or the other forms (taking into ac- count the great variability of the insects). In the present one the elytra are either smooth, without transverse ru- gosities (male?) or the latter are present. There is also a minute tooth visible on the posterior femora (of which Mr. Baly makes no mention) and the last joints of the antennae are distinctly dilated. Co7'ijnodes angulicollis , n. sp. Broadly-oblong, robust, metallic bluish green. Antennae black. Head coarsely punctured. Epistome not separated. Thorax transverse, sides distinctly angulate before the middle, coarsely punctured. Elytra with basal depression, moderately strongly punctate-striate. Claws appendiculate. — Length 4 lines. Head closely impressed with coarse and finer punctures and with a short longitudinal central groove. Epistome contiguous with the front , coarsely rugose-punctate , of a semitriangular-shape. Labrum black. Antennae of half the length of the body, the terminal joints gradually increas- ing in width , but not transverse or clubshaped , five basal Notes from the Leyden IMuseuixi, Vol. "VI, CORYNODES ANGULICOLLIS. 23 joints slightly shining, metallic greenish, the rest black, opaque. Thorax broader than long, the disk very convex, all the angles produced into a short tooth , the sides straight from the base to the middle, above the latter obliquely narrowed towards the apex , forming a distinct angle at the lateral margin; surface closely covered with very deep oblong punctures , which are more distantly placed towards the base; an obsolete oblique depression is visible at each side near the posterior margin. Scutellura small, oblong. Elytra parallel, robust, distinctly depressed below the base, with a narrow margin from the shoulder to the apex , metallic green , with a purplish reflection towards the sides; surface finely geminate punctate-striate near the suture, rather coarsely and irregularly punctured near the sides, where the interstices, especially near the shoulders, are somewhat rugose; punctuation towards the apex more finely impressed. Underside purplish-blue , thinly covered with fulvous hairs. Tibiae entire. Claws appendi- culate. A single specimen from Doesoen Tengah (Sumatra-Ex- pedition). Amongst those species , in which the epistome is conti- guous with the front, the present one is at once separated by the angulate sides of the thorax , its coarse punctuation and the gradually thickened antennae. Corynodes Balyi, n. sp. Broadly ovate , convex , entirely dark violaceous. Epi- stome separated. Antennae with a broad five jointed club, black. Thorax closely but obsoletely punctured.

Antennae of half the length of the body, the six basal joints slender, the 5 terminal ones compressed, broadly dilated, bluish black. Thorax distinctly narrowed in front, the sides greatly deflexed anteriorly, anterior angles produced into an acute point , the latter distinctly thickened ; sides nearly straight near the base , rounded towards the apex , surface closely impressed with larger and smaller punctures , the punctation itself but little deeply impressed and partly obsolete. Scutellum slightly longer than broad, smooth. Elytra broad, a little widened below the middle , impressed with a narrow and rather shallow transverse groove below the base which terminates at the sides below the shoulder in an obsolete tubercle, the latter at the same time being contiguous with the humeral callus ; surface evenly and finely subgeuiinate punctate-striate , the punctures becoming very fine towards the apex; a row of transversely shaped and deep punctu- res runs parallel with the lateral margin. Tibiae not notched, the intermediate pair flexuose. Claws appendi- culate. A single specimen from the District of Rawas (Sumatra- Expedition). To be separated from its congeners by the entirely vio- laceous blue colour, the obsolete punctuation of the thorax, the fine and even punctures of the elytra and their lateral tubercle, as well as by the absence of any costae near the sides. Cori/nodes fraternus , Baly. It is very probable , that Mr. Baly's description of this species was drawn from female specimens. The Sumatran collection contains four insects , one male from Mesauw and three females from Soeroelangoen and Koetoer. The Notes from the Ijeyden Museum, Vol. VI. CORYNODES FRATERNUS. 25 latter agree with the author's description , with the ex- ception that the broadly dilated joints of the anten- nae are not black but purplish blue. The space between the epistome and the trilobate front is covered with dense fulvous pubescence. In Mr. Baly's description the thorax is given as one fourth broader than long , in the specimens before me , it is at least twice as broad as long. It is therefore possible that the Sumatran specimens represent another species, but I am unable to distinguish it from the author's description sufficiently to come to a definite conclusion, without having seen the type. Chrysom,elinae. CJu'ijsomela siimatrensis , n. sp. Oblong-ovate, convex, metallic greenish black. Thorax subremotely punctured. Elytra fulvous, rather finely and irregularly punctate-striate. — Length 3 — 5 lines. Head with a few fine punctures and a more or less distinct fovea at the vertex. Antennae extending to one third the length of the elytra, the first 6 joints metallic green , the rest opaque , black.

Elytra fulvous, con- vex , widened below the middle , finely and irregularly punctate-striate. Of this species which is easily separated from C. stictica Stal by the fulvous elytra, which are also much more finely punctured than in that species, one specimen only is contained in this collection ; it is captured at Solok by Mr. J. H. Schagen van Leeuwen. Others which are before me from Sumatra agree in everything but the shape and punctuation of the thorax which seem very variable. So- metimes the sides of the latter are nearly straight and the Notes from the J-ieyden IMuseum, Vol. VI. 26 CHRYSOMELA SUMATRENSIS. disk is more closely punctured, iu other specimens the thorax is more transverse, the sides more thickened and rounded and the punctuation more remote. The elytra also show some diffei-ence in the arrangement and depth of the punctures , scarcely one specimen being alike , but I have no doubt that they all represent but one form. Chcdcolampra violaceipeiinis , n. sp. Below black. Head, thorax and anterior femora rufous. Elytra violaceous or greenish metallic blue, finely punctate- striate. — Length 2^\^ — 3 lines. Head impunctate. Second and third joints of palpi in- crassate, of equal length, 4th joint very short, acute, conical. Antennae black , third joint twice as long as the second one , the intermediate joints slightly dilated at their apex, the antennae extending to more than half the length of the elytra. Thorax transversely convex, the sides much rounded and widened towards the middle, narrowly mar- gined , anterior angles produced in a short tooth , surface impunctate , rufous. Scutellum piceous. Elytra slightly widened at the middle , closely and finely punctate-striate. Posterior portion of the breast, the abdomen and legs black, finely pubescent, the four anterior femora and rest of the underside rufous. Claws appendiculate. Three specimens, which have been captured at Alahan pandjang , in the District of Rawas and at Lebong (Su- matra-Expedition). Chapuis in his diagnosis of this genus , gives an erro- neous description of the proportionate length of the joints of the maxillary palpi. In C. IS-guttata Fabr. the 3rd and 4th joints are equal (the latter is not of double the length); in the present species which is a true Chakolam- pra , the last joint is acute and short and the 2 preceed- ing joints are of equal length, there are however no other structural differences to justify its separation.

All the Sumatran specimens differ in the obscure rufous colour of the head and thorax , black underside and larger size. In other respects they agree with the Australian forms.

Thorax one half broader than long, the lateral margins very slightly but rather regularly rounded , straight near the extreme base , poste- rior angles acute, anterior ones more indistinct; basal sulcation moderately deep and sinuate, the space behind it finely but distinctly and rather closely punctured , rest of the surface extremely finely and irregularly punctate. Elytra elongate , narrowed towards the extreme apex only, the latter rounded, of a leaden bluish colour, extremely closely and rather finely punctured, the interspaces form- ing narrow obsolete longitudinal costae more or less distinct ; a strongly raised costa extends from the shoulder to below the middle where it disappears.

Specimens from Soepajang , Datar , Silago , Moeara La- boe , Soeroelangoen , Koetoer and Mesauw (Sumatra-Expe- dition) , a single one from Soekadana (I. C. van Hasselt). I do not think to err in separating this species from the other described Eastern forms , on account of its more elongate shape, peculiar leaden bluish colour, punctured thoi'ax and costate elytra.

It is however much smaller and of a dark green colour, and the an- tennae have only the first 3 joints fulvous. The present insect is also much narrower and of more parallel shape. Nisotra gemella , Ericlis. The description of this author agrees so perfectly with the numerous specimens from various localities of this collection , that I should not be justified in considering the latter to repre- sent another form , although the shape varies greatly in the insects before me, and Erichson describes the type from the Philippine Islands. All the insects before me are black or piceous below, with the first 5 joints of the antennae, the head, thorax and legs rufous. The elytra are gemi- nate punctate-striate anteriorly , the punctuation varying however in depth and intensity. The thorax has the usual longitudinal groove at each side of the anterior margin.

This species must be placed iu tbe above genus of "vvliich it possesses all the structural characters. It may be easily recognised by the nearly black elytra which have a large white patch extending from the middle to nearly the apex. The head and thorax are impunctate. The antennae are about as long as half the body, the middle joints thicker than the terminal or basal ones, the 3 lat- ter fulvous. The white elytral patch varies in size and is sometimes of a semilunar shape. In this collection there is a specimen from Loeboe Ge- dang , Moeara Laboe , and Palembang (Sumatra-Expedition). Imolia , nov. gen. Body broadly ovate. Eyes entire, large. Palpi robust, fourth joint small conical. Antennae short, third joint longer than the fourth , terminal joints transverse. Thorax narrowly transverse without depressions. Scutellum broadly triangular. Elytra widened behind, irregularly and closely punctured , their epipleurae prolonged below the middle. Posterior tibiae with a strong spur. First tarsal joint of posterior legs as long as the two following ones united. Prosternum extremely narrow. Anterior coxal cavities closed. The genus proposed here bears great resemblance to the genus SpliKrometopa from which the closed anterior cavi- ties at once divide it. Other differences are to be found in the relative length of the basal joints of the antennae and in the longer first joint of the posterior tarsi in the present genus. Imolia idgrofasciata , n. sp.

Elytra as closely but more strongly punctured , flavous , all the margins , the base and a narrow band across the middle black. Tibiae sometimes obscure piceous. Underside and legs fulvous. Posterior femora strongly incrassate. One specimen from Moeara Laboe , and two from the District of Rawas (Sumatra-Expedition). The flavous colour of the elytra assumes in some speci- mens a metallic golden hue , while in others it is more opaque. The black markings vary also somewhat in width, so that one may consider either the ground colour, the epipleurae are however black. The species bears a great resemblance to Spha'rometopa ornata Baly , (which ought to be placed in this genus , as I have compared the type and find the coxal cavities closed) , but the markings of the elytra in all the specimens of the present insect differs from Mr. "Baly's species.

Prosternum very narrow but distinct. Anterior coxal cavities closed. Posterior femora very moderately incrassate. The transverse thorax , very short second and third joints of the antennae in connection with the length of the latter and the closed coxal cavities will distinguish this genus from any others with which I am acquainted , its place being perhaps best found amongst Chapuis' 8th group the Oxygoninae, while the posterior femora , although less strongly developed than is generally the case, are yet sufficiently incrassate as to leave no doubt as to the position of the insect in the Halticinae.

Head finely punctured at the vertex , with a narrow transverse groove above the eyes. Frontal tubercles very flat, divided. Antennae rather short, four or five basal joints fulvous, the rest black, third and fourth joints equal, second joint short. Thorax transverse, widened at the middle, the sides rounded and narrowed towards the apex, surface distinctly and rather closely punctured, with a longitudinal obsolete groove at each side. Scutellum triangular, obscure fulvous or piceous. Elytra very con- vex, slightly widened towards the middle and narrowed near the apex, strongly and regularly punctate-striate. Posterior femora strongly incrassate, their tibiae with a spine. Prosternum longitudinally excavated. Mesosternum very short. Anterior coxal cavities open. Specimens from Boekit Kandang, Solok and Soeroelan- goen (Sumatra-Expedition). I am somewhat doubtful whether the true position of this species is in the genus Sphceroderma on account of the regularly puuctate-striate elytra and the longitudinal groove (which although obsolete is present in all the specimens) near the sides of the thorax. The shape of the insect also is less rounded than is generally the case and resembles much the genus Phcedon amongst the true Cbrysomelinae.

In all structural characters, this species agrees with the preceeding one but is at once separated by the double rows of punctures and the entirely violaceous elytra. I think it very probable that both species are representatives of a new genus. Spluvroderma ((rvipevnis , n. sp. Rotund ate-ovate , fulvous below , above obscure piceous.

The 3 basal joints of the antennae are fulvous. The thorax has the sides narrowly flattened and accompanied by an im- pressed groove. The posterior femora are very strongly incrassate.

The antennae have the last 6 joints black , the basal ones testaceous beneath , fuscous above. Thorax impunctate, elytra deeply but remotely punctured. Legs and breast as well as the head are black , the other parts testaceous. Aidacophora I'osea Fabr. » dimidiata? Guer. Two exactly similarly coloured species, varying from each other in size only, contained in this collection and brought home by the Sumatra-Expedition , must be refer- red to either of the two above insects which are probably identical. In both the entire underside, thighs, head and thorax are red; antennae paler, the second joint of which is very short. The elytra are black from the base to below the middle , the remaining portion being bright rufous , the entire upper surface very shining. Elytra very finely punct- ured , with a deep depression below the scutellum and a distinctly widened lateral margin. Tibiae and tarsi are black. All the larger specimens (from Sidjoendjoeng and Moeara Laboe) vary from 5 to 6 lines , the smaller ones (from Boekit Kandang , Boea , Solok , Rengkiang Loeloes , Silago , Moeara Laboe , Soeroelangoen and Palembang) from 3 to 4 lines. Of the larger ones only females are before me, but of the smaller both sexes. The description given here agrees perfectly with either of the above named and described species , but while Guerin gives the length of his species at 8 mill. , Fabricius does not indicate the size at all. Notes from the Leyden ]VIiiseum, Vol. VI. AULACOPHORA ROSEA. 39 I ara however inclined to believe that the larger of the two forms is that described by Fabricius , as the colour of the antennae which are flavous, with the exception of the first joint , which is rufous , agrees well with the author's description. In this form the black colour of the ely- tra is divided obliquely at its posterior margin from the red. In the smaller species the same colour is separated by an almost straight line (as given by Guerin) but there are specimens which vary in this respect. Aulacophora Batesi, n. sp. Oblong, widened behind. Underside and the 4 posterior legs black. Head , thorax , anterior legs and antennae fulvous. Elytra finely punctured, longitudinally costate(9?) or simple, fulvous, posterior half black. — Length 4^/2 — ^^'^ lines. This large sized species , which I also possess from Java, has quite the colour and general appearance of Haplosonyx semijiava Wiedem. from which the structural characters, peculiar to Aulacophora at once distinguish it. I cannot separate those specimens with costate interspaces of the elytra , from those with simple ones , this character being the only difference. In both, the first two joints of the antennae are shining, the rest pubescent and more opaque. The third and following joints are nearly equal, more than twice as long as the second. The scutellum is either black or fulvous and the latter colour of the elytra predominates to a greater or smaller degree. The latter in the costate specimens are opaque, in the other form more shining. The last may possibly represent another species. The specimens before me are from Loeboe Gedang and Soerian (Sumatra-Expedition) and from Soekadana (I. C. van Hasselt). Notes from the Leyden Miasexim, "Vol. VI. 4U AtlLACOPHORA l.UTETCORNIS. Aulacophoru atripennis , Fabr. Specimens agreeing well with Fabricius' description are contained in the collection. The colour of' the legs (not given by the author) is generally black , in others the thighs are fulvous. The underside also varies in coloura- tion , some specimens having the breast black. In all , the antennae are flavous with the exception of the first joint which is more or less brownish , and the elytra , widened behind and depressed below the base , are very finely punctured. In size the species varies from S^/g to 4^/2 lines. A. cyanoptera Boisd. is probably identical with this spe- cies, also perhaps A. >?ig/a»o/)^^ro Boisd. , but the descriptions are too short to come to any conclusion. Aulocophora luteicornis, Fabr. This species is generally received from Sumatra and may be recognised by the rufous elytra, the latter having the apex black. A. simplicipennis Clark seems to me to be identical with the present insect, the only difference, ac- cording to the description, being the entirely rufous ely- tra. In some of the Sumatran specimens in this collection the lateral margin of the thorax is narrowly testaceous. Aulacophora margin ata (V) Chap. The specimens obtained at Sumatra agree with those from Java contained in my collection and named by Chapuis himself, but differing from his description (as already pointed out by me in the » Notes from the Leyden Museum. Vol. V. p. 202). The species is extremely closely allied to A. melanura Oliv. from which it only differs apparently in the colour of the underside which is entirely flavous. The present insect has the elytral margin narrowly testaceous, by which Notes from the Leyden Museum 5 "Vol. ^VJ..

I cannot distinguish the two above species , as the des- criptions are similar. The species from Sumatra, described by Hornstedt , is most probably identical with those in the present collection , although the insect may also have its habitat in India, from which locality Schaller's specimens were described. Aulacopliora coffeoe, Hornst. I refer the specimens obtained at Sumatra to this spe- cies. Many closely allied forms exist " in the Malayan Ar- chipelago and otherwhere. All the specimens of the present species before me , have the vertex of the head piceous, the entire underside and four posterior legs black (Hornstedt says green which is no doubt a mistake as no such coloured species exists). The elytra are opaque and very finely punctured. The transverse thoracic groove is deep and extends to the sides. Malarosoma parvula , n. sp.

The only specimen contained in the collection differs from the type in regard its colour in the following way. The underside , legs , antennae , head and thorax are black, the elytra dark fulvous , margined with black. In the ab- sence of other specimens I am unable to say whether I have a variety or new species before me.

Notes from the Leyden IMuseuin, Vol. "VI, 44 MIMASTRA SUBMETALLICA. From the other described species belonging to Mimastra, the present one may be separated by the very long fourth joint of the antennae and the metallic reflection of the elytra. In the female the last joints of the antennae are generally fuscous and the thoracic depressions are more obsolete. Mhnastra violaceipeimis , u. sp. Elongate , black.

Underside and legs greenish black, finely pubescent, coxae fulvous. Coxal cavities open. Claws appeudiculate. A single specimen from Soepajang (Sumatra- Expedition). This species agrees in every structural character with the exception of the antennae with Cerophysa in which I have at present included it. In the present species the 8th instead of the 6th and 7th joints, is greatly develop- ed , but in the absence of other differences I prefer not to erect a new genus on this character.

Legs unarmed , first posterior tarsal joint as long as the two following ones together. Claws appendiculate. Anterior coxal cavities open. Specimens from Solok , the District of Rawas and Leboug (Sumatra-Expedition). Although this species belongs evidently to the above ge- nus on account of the robust antennae and similarly sha- ped thorax , the different colour of all the specimens before me prevent me in considering them the female sex of C. viridipennis. As all the insects are of this sex I cannot say whether the antennae show the same structure in the male as in the type. Luperodes scuteUatus , n. sp. Oblong-ovate, testaceous.

In the variety, which is from Soeroelangoen , whereas the specimen of the typical form has been captured at Loeboe Gedang, the elytra are entirely black, the femora are tinged with fulvous at the base , and the 2 impressions at the thorax are almost absent. I have provisionally placed this insect in the genus Antipha on account of its distinct prosternum , closed an- terior coxal cavities and unarmed tibiae; the dilated inter- mediate joints of the antennae would perhaps equally well given it a place in the genus Emathea , the latter is however of totally different habit, rotundate and convex. Arcastes has similarly structured antennae , but the coxal cavities in the latter genus are open and the tibiae mu- cronate.

Antennae two- thirds the length of the body, second and third joints very short, of equal length, the intermediate joints slightly compressed and dilated, pubescent, the two last joints testaceous. Thorax transverse , the anterior angles obtusely rounded , anterior margin straight , posterior one slightly rounded , surface scarcely visibly punctured , dark ful- vous. Scutellum of the same colour, trigonate. Elytra distinctly widened behind, very convex, punctured like the thorax, testaceous , a broad transverse basal band , extending to the first third of their length , fulvous. Elytral epipleurae broad and flat, obliquely shaped before the middle where they gradually disappear. Legs fulvous, posterior tibiae with a long spine , first posterior tarsal joint as long as half the tibia. Claws appendiculate.

Thorax scarcely twice as broad as long, lateral and posterior margin evenly rounded, the anterior angles slightly thickened, surface with a sinuate shallow depression extending nearly across the entire disk , very closely and finely punctured. Scutellum black , trian- gular. Elytra convex , very finely and closely punctured , inner margin of the epipleurae black. First posterior tar- sal joint as long as half the tibia , the latter with a dis- tinct thorn. Claws appendiculate. Two specimens from Soeroelangoen (Sumatra-Expedition). The closed anterior coxal cavities , structure of the an- tennae, the tibiae which are all armed with a spine, and the long metatarsus, show this species to belong to the above genus , although in shape it resembles much the in- sects forming the genus Luperodes. Theopea ohliterata , n. sp. Elongate, obscure testaceous. Tibiae piceous. Thorax fulvous , biimpressed , impunctate. Elytra violaceous blue , obsoletely longitudinally costate, the interstices very finely punctured. — Length 2'/2 lines. This species can easily be distinguished from T. impressa Fabr. by its different coloured antennae , which are entirely testaceous , and by the finely costate and punctured elytra which are not transversely reticulate as in the allied spe- cies , and have their epipleurae also fulvous , not blue. Two specimens of this species have been collected at Moeara Laboe (Sumatra-Expedition). Neocharis fulvicoUis , Jacoby. This genus was founded by myself (Proceed. Zool. Soc. London. 1881) on two specimens from Java , differing from Notes from the Leyden Museum, A''ol. VI. NEOCHx\RIS Fü'LVICOLLIS. 57 the allied genera of Platyxanthinae by the deformed di- lated third joint of the antennae. All the specimens contained in the Sumatran collection, obtained at Soeugei- Simauoeng , Moeara Laboe , Loeboe Gedang , Palembang and Soeroelangoen , differ in colour from the typical forms contained in my collection and prove the insect to be very variable in that respect. As I suspected at the time of publication, the females, of which many speci- mens are now before me , differ from the male insects in having simple antennae, in which character they agree with the same sex in the genus Dorydea. From the female in the latter, the same sex of the present insect may be separated by the longer third joint of the antennae which is the longest of all, by the more squareshaped thorax and by the different punctuation of the elytra , which are very finely and irregularly punctured in the female sex. I may add here to my former description that the third joint of the antennae in the male is deeply excavated on its upper surface and slightly indented at its inner margin. I give here the colours of the typical form , and of the varieties from Sumatra : Below black. Head , thorax , antennae and femora ful- vous. Elytra greenish and bluish black, the apex fulvous (typical form). var. a. Elytra with a transverse testaceous dentate band before the middle. Tibiae more or less marked with blackish, var. h. Elytra fulvous , a narrow transverse basal band , another one below the middle , the lateral margin at the same place and the apex bluish black, var. c. Below fulvous , antennae testaceous , 'stained with fuscous , elytra entirely black, var. d. Below black , elytra bluish black , a transverse band at the middle fulvous. Between all these forms , several intermediate stages are to be found as well. Notes froTO the Leycleu Museum, Vol. VI, 58 XENODA SPINICORNIS. Xenoda spinicornis , Baly, Elongate, testaceous. Head and thorax impunctate. Ely- tra dark purplish , finely transversely rugose and sparingly pubescent. — Length 3 lines. Head with a transverse ridge between the eyes , the space between the antennae very narrow , raised , and divided longitudinally by a groove. Clypeus transversely triangu- lar. Antennae scarcely half the length of the body, tes- taceous, the second joint very short, the five following joints forming an elongate thickened club and ending in a long and acute spine, the next joint as long as the five preceeding joints together, the two terminal joints rather short. Thorax narrowly transverse , the sides straight , an- terior angles slightly tuberculate, posterior ones obsolete, surface with a deep transverse depression which does not quite extend to the sides, entirely impunctate. Scutellum broadly triangular. Elytra of a purplish violaceous or green- ish colour , according to the position the insect is held , the suture however of the former colour, surface entirely covered with transverse wrinkles without punctuation , the sides and apex sparingly covered with stiff hairs. Legs testaceous , first posterior tarsal joint as long as the 3 fol- lowing ones together. Claws appendiculate. A single specimen from Moeara Laboe (Sumatra-Expe- dition). I have given a renewed description of this species, which varies in the colour of the antennae, legs and underside from the typical form, but I believe in no other respect. Xenoda hïrtipênnis , n. sp. Testaceous. Head and thorax impunctate. Elytra ex- tremely finely punctured , closely pubescent , testaceous , the basal margin and a lateral longitudinal band, extending nearly to the apex, black. — Length 3 lines. Notes from the Leyden Miuseum, Vol. VI. XENODA HIRTIPENNIS. 59 This species agrees in everything with the preceeding one in regard to structural details, the elytra are however differently sculptured , not rugose , and closely covered with testaceous pubescence , besides being of different colouration. The antennae are of the same curious construction and colour but the two apical joints are wanting. A single specimen from Moeara Laboe (Sumatra-Expe- dition). Macrimai^) pallidicornis , n. sp. Oblong-ovate , black. Antennae and tarsi pale fulvous. Thorax transversely biimpressed, impunctate. Elytra dark fulvous or black , finely and closely punctured. — Length 3^/2 lines. Head impunctate , transversely grooved. Clypeus triangu- lar, thickened. Antennae two-thirds the length of the body, filiform, the third joint twice as long as the second, pale fulvous , basal joint piceous above. Thorax transverse, the anterior and posterior margins rounded , the sides evenly rounded , anterior angles thickened , surface with a transverse depression at each side extending nearly across the entire disk , the latter impunctate. Scutellum trigonate. Elytra much widened behind, convex, very closely and finely punctured , black or fulvous. Tibiae rather curved , the 4 posterior ones with a long spine, their first tarsal joint of half their length. Anterior coxal cavities closed. Claws appendiculate. Specimens from Datar, Alahan pandjang, Moeara Laboe and Lebong (Sumatra-Expedition). I have provisionally placed this species in Mr. Baly's genus Macrima (Cistula 1878) as it agrees in the closed coxal cavities and in all other respects with the description of the author. The only differences are the robust, poste- riorly dilated shape of the present species and the long Notes from the I_ieydexi DMuueuxn, "Vol. VI, 60 MACRIMA.

Tibiae mucronate, first posterior tarsal joint as long as the 3 following ones together. Anterior coxal cavities closed. Underside black , sides of the abdomen and the last abdominal segment more or less testaceous. Claws appendiculate. Specimens have been captured at Moeara Laboe, Mesauw and Soeroelangoen (Sumatra-Expedition). At first sight this species resembles Aulacophora abdo- minalis Fabr. from which the structural difierences pointed out above , will at once distinguish it. Caritheca sumatrensis , n. sp.

Scu- tellum black , trigonate , its surface rather convex. Elytra wider than the thorax , convex , longitudinally excavated near the lateral margin before the middle , their surface closely and slightly rugose-punctate, with indications of narrow and smooth longitudinal costae. Underside and femora flavous, apex of the latter and the tibiae piceous. A single specimen from Loeboe Tarab (Sumatra-Expe- dition). Separated from C.

Strohiderus excavatus , n. sp. Elongate , pale fulvous. Thorax extremely finely punct- ured. Elytra strongly punctate-striate with convex inter- stices, fulvous, pubescent, the apex black, excavated and produced (cf). Female with simple elytra. — Length 2^/3 lines. Head impunctate , the vertex with a transverse blackish band. Eyes very large , black , the space between them somewhat depressed towards the lower portion. Antennae as long as the body, all the joints, with the exception of the very short second one, slender, of equal length and very elongate, covered with rather long hairs. Thorax twice as broad as long, rather convex, sides rounded, the anterior angles entirely obsolete , the posterior ones acute , surface extremely finely punctured , slightly wrinkled. Ely- tra closely covered with yellow pubescence , deeply and regularly punctate-striate , the interstices longitudinally costate , fulvous , the extreme apex black. The latter pro- duced in a spoonshaped protuberance at each elytron , proceeded by a deep excavation or hole extending into the elytra. Legs slender , first tarsal joint as long as half the tibia, the latter with a long spine. In the female the antennae are shorter and the elytra are slightly truncate at the apex. A male and a female have been taken in the District of Rawas (Sumatra-Expedition). Glyptolus , nov. gen. (Sect. Scelidinae). Body elongate, parallel. Head exserted. Eyes large, en- tire. Labrum broad, entire. Palpi slender, the last joint Notes from the Leyden Miuseutn, "Vol. "VI. glyptolus. 63 very pointed.

Legs slender and thin , tibiae unarmed , first tarsal joint as long as the three following joints united. Claws appendiculate. This genus will find its place in the 12th group of Chapuis' arrangement , on account of the open coxal cavi- ties, unarmed tibiae and appendiculate claws. The trans- versely depressed thorax and the pubescent upper surface will separate it from the other 2 genera forming this section. Glyptolus viridis, n. sp. Elongate , parallel , black below. Legs and thorax testa- ceous , the latter with a central black spot. Elytra metallic gi'een, the lateral margin narrowly purplish, surface finely granulose-punctate , finely pubescent. — Length 3 lines.

Thorax transverse, the sides straight, narrowly margined, surface without depressions. Scutellum trigonate. Elytra convex, closely punctured, the punctures semiregularly arranged, their epipleurae prolonged below the middle. Legs slender. Tibiae with a small spine. Posterior first tarsal joint longer than the 3 following ones united. Claws appendiculate. Prosternum very narrow, coxal cavities closed. 9- Antennae with the third joint simple. The above characters will place this genus in Chapuis' 20th group , from all of which I am obliged to separate it by the incrassate penultimate joint of the palpi. In its other structural characters it approaches the genus Leptar- tlira from which it must however be separated by the different comparative length and structure of the antennae and different shape of the elytra which are devoid of any basal depression. Malacotheria Fairm. has a differently shaped thorax and scutellum. Macrima Baly differs in the thoracic depression, not incrassate palpi and different comparative length of the joints of the antennae. JS'otes from the Leyden nXuscuixi, "Vol. Vi.

Another specimen from Java in my collection varies in the flavous abdomen spotted with black at the sides, in having the thorax two-spotted, and in the posterior oblong patch at the elytra which extends upwards to the middle. This species ought to be placed in Sphenoraia according to the present definition of the genus (Baly, Cistula 1879), as it possesses all the structural characters and is devoid of the basal elytral depressions as seen in Haplosonyx. I have no doubt that the present species is identical with S. javana Wiedem., whose description is very accurate and agrees in nearly every respect with Mr. Baly's species. It is no doubt however, subject to variation in colour. London, October 30th, 1883. 1) Ann. and Mag. of Nat. Hist. Bth ser. Vol. IV (1879). p. 115. Notes from the Leyden IMuseum , "Vol. VI.

Head broad, rather finely -and closely punctured , with a moderately strong oblique impression on each side just in front of the eyes. Epistoma rather more finely punctured than the head. Antennae reddish testaceous. Prothorax about twice as broad as long, with a semicircular and rather deep eraar- gination in front , very finely and closely punctured ; all the angles slightly obtuse ; the sides gradually rounded. Scutellum large , rounded behind , extremely finely punc- tured. Elytra at the base very slightly broader than the prothorax , about twice as long as the head and prothorax together, somewhat narrowed posteriorly, moderately strong- ly and irregularly punctured , with traces of feebly elevated lines representing costae; humeral angles not prominent, reddish testaceous ; sides nearly parallel for about one third of their length , then rounded to the apex : each elytron with three longitudinal rows of small spots on the disk, and a somewhat larger spot near the scutellum reddish testaceous; these spots are not constant in size, but usu- ally those just behind the middle, on the disk, are some- what larger than the others. Under side coloured as above ; the pro- and mesosternum rather coarsely and close- ly punctured; the metasternum more finely and less closely so , abdominal segments and under-margins of the elytra almost as strongly punctured as the mesosternum. Legs pale brown ; apical half of the femora reddish testa- ceous. — Length 6^/4 — T^/g mm.; greatest width S^/g — 4^/4 mm. Sumatra (Ludeking). Unlike any species of Lasiodactylus known to me, but nearest to L. tibialis Boh. from Natal; it is, however, a much narrower insect and duller in colour, it also differs in the punctuation of the under side, and in having the apical half of the femora testaceous.

Ver. Brünn. XIV". pi. 2. fig. 33) does not agree with the type of that species; the head as represented by him being much too broad (thus approaching L. incensa) , the pro- thorax not sufficiently long , and the emargination too deep. The prothorax in L. ovalis is 2^3 times as broad as the head ; and its length in the middle is equal to the width of the head. In other respects , the figure agrees best , although but indifferently, with Mac Leay's species. Gaurambe Reitteri, n. sp.

A. S. 0. Notes from the Leyden Museum, Vol. VI. HERMANN SCHLEGEL Born June 10th, 1804. Died January 17th, 1884. In him , Natural Sciences have lost one of their most eminent students who ever existed. His name was known and highly honoured by every scientific man. Humble and not vainglorious he only lived for and in his Museum, his home, his glory, where he worked during more than half a century, and what he advanced to the most celebrated collec- tion in Europe. Through his comprehensive know- ledge in nearly all branches of science he formed the most valuable Museum for the study of the limits of variation in species and for that of the geogra- phical distribution of the Animal Kingdom , arran- ging it in the most scientific way. Nearly each of the large number of his publications is a standard- work. Fading eyesight had for some time before his death prevented him from following his studies with the same success as formerly , but there are few who have so disinterestedly devoted their lives to zoological pursuits, and to whose memory greater respect is due. The Leyden Museum of Natural History and his writings form a monument more lofty and more noble than the finest and most splendid monument of marble. 1^ ■■■■■^■i^^l^HHi 1 DARALA. 81 NOTE VIL A NEW GENUS AND SPECIES OE THE HYMENOPTEROUS EAMILY LARRIDAE DESCRIBED BY C.

This species , by its slender and delicate structure , on the first sight is hardly to be recognized as an Asilid. Head rather large, broader than the thorax, nearly wholly occupied by the eyes; front and face very narrow, silvery white ; front with a longitudinal groove ; vertex small, deeply sunk in a narrow slit between the eyes; face on the upper part with a longitudinal groove, on the lower part a little prominent and gradually enlarging to- wards the mouth. Mystax not reaching beyond the middle of the face and consisting of a few long, partly yel- lowish , partly white hairs ; beard whitish. Eyes large , descending on both sides beneath the oral margin; middle facets larger than the outer ones. Occiput impressed.

Thorax uniformly pale rufous, on the sides and before the scutellum with a few yellow bristles. Abdomen slender, rufous; the hind margin of the third and fourth segments brownish; the following segments entirely of this colour and somewhat shining ; at the under surface of the second and following segments a rather long and dense , mostly yellow pilosity is present ; genitals small ; inferior appendices cylindrical , with the tips turned towards each other and with a long hair at the base. Legs of moderate size and strength , pale yellow. Middle and hind femora with a pair of brown points at the tip* The second joint of the front tarsi elongated, even a little longer than the first, each of these joints with a black point on the underside. First joint of the middle tarsi as long as the following joints taken together , its tip in- fuscated and feathered outwards by a tuft of black hairs; the three following joints brownish , remarkably short and broad, feathered in the same way as the tip of the first joint; on the underside the first and second joints have a black point. Of the hind tarsi the first joint likewise is nearly as long as the following joints together, but these are not so short and broad as those of the middle tarsi, and have no tuft of black hairs, but they are a little in- fuscated at the tips. Pulvilli and claws yellow , the latter with a black tip. Bristles and pilosity of the legs for the most part yel- low; front coxae on the lower part densily beset with white hairs.

Wings rather narrow , hyaline with the tip cinereous ; veins blackish; the space between the costal and subcostal veins, in the distal half of the wing, is somewhat infus- cated. The two longitudinal veins issuing from the discal cell, together with the inferior branch of the external sub- marginal cell, are strongly curved; middle crossvein in- serted at about two-thirds of the discal cell , which is rather elongate and narrow; fourth posterior cell closed and appendiculated at its proximal as well as at its distal end. A single male specimen from the island Waigiou (Bern- stein) in the Ley den Museum. By its tender structure, its narrow face and front, the peculiar shape of its tarsi and the unusually waved veins in the apex of the wings, this species differs so much from the other species of Ommatius, that most pro- bably future investigations will show the necessity for ma- king a separate genus for its reception. I dedicate this very distinct species to the memory of the late Professor H. Schlegel, the regretted Director of the Leyden Museum. the Hague, February, 1884. Notes from the Leyden Museum, "Vol. VI.

La troisième espèce , la Pot. Ambolnensls Felder , Sitz.

Elle se trouve du reste dans l'ile d'Amboine comme la Pot. Alhata. Je suis incline a croire que les parties chaudes de l'Asie Meridionale et de l'Australie Septentrionale sont habitées par quelques autres espèces de Potamophora , parentes de Manila. Une des mieux tranchées de ces espèces se trou- vait depuis longtemps dans la collection du Musée de Leyde , sous un nom provisoire donné par feu Mr. de Haan. Elle y Notes from the Leydeii IMuseum, "Vol. VI. 88 POTAMOPHORA SCHLEGELII. est representee par les deux sexes (un cf et uue 9) et a été rapportée de Java par Mr. Ie Prof. Reinwardt. Je profite d'uue occasion qui m'a été offerte pour la publier et je m'em- presse de répondre en même temps au voeu de Mr. Ritsema , Conservateur de la partie entomologique du susdit Musée , en dédiant cette espèce a la mémoire du savant illustre qui pen- dant tant d'années a illustre l'établissement qu'il dirigeait. Les deux individus sont de grandeur presque egale et out une envergure de 77 a 78 millimetres. Palpes, tête , antennes et thorax sont d'une couleur gris-brunatre foncé , cequi est aussi la nuance du fond des ailes supérieures. Celles-ci sont un peu plus claires vers la base et devien- nent insensiblement , surtout chez la femelle , d'un ton plus foncé vers Ie bord postérieur. Les tacbes ordinaires dans la cellule discoïdale et un espace qui occupe Ie troi- sième quart du bord intérieur au dessous de la cellule et de la nervure 2<^ sont plus clairs , d'un brun de bois jaunatre , Ie dernier espace étant , de plus , semé d'écailles d'un noir brunatre. Contour des taches ordinaires mal tracé, noir; celui de l'orbiculaire ouvert par Ie haut, celui de la réniforme encore plus vague, ouvert en bas et en haut, Ie cóté basal un peu arrondi, Ie contour postérieur avec une dent aiguë en forme de bec d'oiseau. Sur Ie bord intérieur on remarque un dessin assez apparent en forme de fer de cheval. Il est tracé par une ligne courbée noire , bordée d'une seconde ligne jaune grisatre et qui, en par- tant du premier quart du bord, s'élève jusqu'a la cellule discoïdale , se recourbe ensuite , vient rejoindre Ie bord in- térieur vers son milieu et limite l'espace clair, pointillé de noir dont j'ai parlé ci-dessus. Un commencement de ligne noire se voit au bord antérieur avant l'orbiculaire. Sommet de l'aile divisé par une nuance ferrugineuse un peu en zigzag a partir de la nervure 5^ et ombrée en des- sous et en arrière de noir. Ailes inférieures d'un brun grisatre jusqu'aux trois quarts. Ensuite vient une bande d'un bleu clair un peu violatre qui part du bord antérieur et s'arrête assez abruptement Notes from, the Leyden ]M\xseum, Vol. "VI. POTAMOPHORA SCHLEGELII. 89 a la nervure 5^. Cette bande est incisée vers la base , un peu dentée extérieurement et n'occupe que Ie cinquième de la largeur de l'aile. L'espace qui avoisine l'angle anal de l'aile est nuance de brun de bois et fortement strié de noir. Le reste de l'aile a une couleur d'un brun un peu noiratre. Dessous des ailes supérieures d'un gris-brunatre , niarqué d'une bande d'un blanc bleuatre qui va de la cóte a la nervure 2^. Elle est coupée droite du cóté basal , d'une lar- geur d'un millimetre environ du bord antérieur a la ner- vure 5^ , puis s'élargissant tout a coup jusqu'a 5 millimetres jusqu'a la nervure 2^. Dessousdes ailes posterieures jusqu'aux trois quarts en- tièrement d'un blanc bleuatre , un peu mêlé de brun-gris- atre chez la femelle, assez pur cbez le male ou il est seu- lement sali vers la base et marque sur la nervure discoï- dale d'un trait brun-grisatre. Le reste de l'aile est d'un brun-grisatre , borde du cóté de la base et tout contre la partie claire d'une ligne ondulee d'un blauc-bleuatre qui se confond même entre les nervures avec la partie claire. Abdomen et jambes d'un brun grisatre, les éperons et la partie intérieure des tarses plus clairs, jaunatres. Cette espèce se distingue done de la Manila et de VAm- hoinensis par le dessous des ailes posterieures , de la Manila en outre par l'étroite bande bleue de la surface de ces ailes , par le manque de la ligne droite qui traverse chez cette dernière les ailes antérieures. De plus , les deux sexes de la Schlegelli ne différent pas , tandis que chez le male de la Manila on remarque vers le milieu de l'aile , dans la cellule 2e, un trait épais, horizontal et d'un noir pro- fond coupé droit du cóté supérieur. Ce trait manque chez la Schlegelli. Il y a de plus, une foule de petites diffe- rences secondaires que je ne détaillerai pas ici , me proposant de donner une figure de ma nouvelle espèce dans le Tijd- schrift voor Entomologie, peut-être en y ajoutant une de la Manila , grossièrement representee dans l'ouvrage de Cramer.

The colour is a little different, the suture not being ever distinctly dark , but in paler specimens the elytra are simply more deeply pitchy there and at the middle of the sides than in the middles. The punctuation is so pre- cisely similar that it would not suffice to distinguish them. Crotch (Cocc. Rev. p. 273) has proposed a genus Ani- soscymnus for Sc. rufipes Fabr. which he says will be well represented in the Malay Archipelago. But he has not described any species.

THYRIDOPTERYX EPHEMERAEFORMIS. 129 NOTE XIX. ON THE EXOTIC PSYCHIDS IN THE LEYDEN MUSEUM F J. M. HEYLAERTS. The collection of exotic Psychids in the Leyden Museum is far from being an extensive one , as there are only four species and the larval cases of two others. One of the latter (notwithstanding its being unique) was worth to be described. Moreover the species were not , or incorrectly named and of course required revision. — Mr. Ritsema kindly allowed me to examine all the specimens and to publish the following results of my examination in the » Notes from the Leyden Museum." 1 . Thyridopteryx ephemeraeformis Steph. — One cf . This well-known insect was labelled: Oiketicus nuda (Boisduval, Louisiana). 2. Eumeta Layardii Moore. — One cf. This species , described and figured by Mr. Frederic Moore in the sLepidoptera of Ceylon" (part VII, p. 102; Plate 118, fig. 2, cT, 2a, larval case) was represented by a worn male specimen brought home from Solok by the Scientific Sumatra-Expedition (vide ; Midden-Sumatra. Lepidoptera. p. 30 : Oiketicus spec). The large size , the shape and pattern of the forewings , the black and stout antennae distinguish it immediately. Formerly Mr. Hoedt had forwarded to the Museum the very large larval cases of this species , found by him in the Moluccas. One of these belongs to a male ^Notes trom the Lfiyden Mnseum , "Vol. VI. 130 EUMETA LAYARDII. specimen , the others (four) to the female insect. The caterpillar being not yet described, I have taken the fol- lowing description of it : Length about 5 centim. — Head broad , rounded , yellow , sparingly beset with long hairs; the labrum and mandibles are black , the former slightly notched in the middle ; the antennae jointed, yellowish white. A double f urea, formed by black lines , running down to the labrum , sur- rounds the clypeus and the face. Laterally three longitu- dinal , short , black streaks (above) and three little black patches (beneath), as well as the brown ocelli , are to be found. The three thoracic segments are covered with horny , polished shields of an amber yellow color. The first is provided with six longitudinal black lines , three on each side of the broad lighter coloured middle space, which shows two divergent groups of black points. The pattern of the two following shields is uniform : four longitudinal black lines, the inner ones curved, not reaching the up- perside of the shield, the outer ones straight. The following (eight) segments are of a dirty yellowish color, somewhat greyish , the terminal one covered with a yellowish brown, black-bordered scale, and, as well as the thoracic ones , sparingly beset with hairs. — The under- side is lighter, of a more or less greyish yellow color. The stigmata and the broken stigmatic line are brownish. The forelegs are horny, brown and yellow-ringed, the first joint is brownish striked on the exterior side. 3.

This species, which is one of the most interesting Psy- chids, certainly does not belong to the genus i^iimea Hübn . (vide my description of the gen. Heckmeyeria Heyl., Compte- rendu Soc. ent. Beige, 7 Fevr. 1880). It is still yet represented in the Leyden Museum by the type-specimen ouly , which has been found in East Java (Mount Ardjoeno) by Mr. W. E. J. Heckmeyer. 5. Species incertae sedis : (Eumeta?) Salae , nov. spec. Mr. Biittikofer and the late Sala have found in Liberia a larval case (with a full-grown larva) of a Psychid , which , without knowledge of the perfect insect, cannot be named with certainty. Psychids however have larval cases, dif- ferently shaped for each species, and therefore they may be named notwithstanding the imago is unknown. The genus however remains ipse facto uncertain. Besides the Psychids there is a large number of case- Notes from the Leyden MLu.seu.iii, Vol. VI. 132 (eumeta?) salae. making genera ; but as each species of them composes its dwellinghouse on a different manner, specific names may be given also in these genera; generic ones however only when the imago is known. I therefore propose to name the Liberian Psychid y)Salae'^ in honour of Mr. Sala, the zealous naturalist, who fell a victim to the unhealthy climate of that Republic. The larva . which resembles not at all that of Mod- dermanni Heyl., is of a blackish colour; I estimate (the larva being dried) the length to be 2,5 centim. The head is yellow , the labrura and mandibles are black , the former notched ; the clypeus is divided by a black streak and the face is surrounded by a black furca. On each side five short curved black streaks (above), and two ditto points together with the brown ocelli (beneath) are to be found. The antennae are whitish yellow. — The head , as well as the body, is sparingly beset with hairs. The shields which cover the three thoracic segments , are yellow. The first shows four longitudinal black lines, of which the inner ones do not reach the upper side of the shield, and are somewhat truncate above; the outer ones are slightly curved, and in the space between the inner and outer ones , above and beneath , a black point may be observed. The second shield has only four black lines , but the third differs much. In the middle an Y-shaped black figure is present and on each side two black streaks , the first of which is short, thick and curved. The stigmata aud the broken stigmatical line are brownish. — The following segments are blackish , with the terminal one covered with a broad , black scale. — The forelegs are brownish, the joints blackish beneath. The abdominal and anal feet are blackish. The larval case measures 4,3 centim. in length and is 1,5 centim. broad; it is cylindric and covered with twigs of equal size , nearly as long as the case , fastened through- out their whole length , and arranged with much regularity. The superior end is not covered, the silk is dark greyish. ISTotes from tlie Leyclen JVXuseum, Vol. VI. SPIROCERA CORAS. 133 Mi,€»nnt*hs, 1 . Among the Psychids in the Museum there were three small moths labelled: Oiketicus Coras Cram. Two of these, a male and a female from Surinam , are very old and from the collection of Mr. Raye van Breukelerwaard (these are inter alia most probably the specimens described and figu- red by Cramer himself in his Papillons exotiques, IV, p. 46; pi. 312, fig. A, from the collection of Mr. W. van der Meulen) ; the Brd , from Brazil , is from the collection of Mr. van Eyndhoven. — Authors have placed this species in different genera, but the neuratiou of the wings and other characters show that it belongs to the Cossina sensu Herrich-Schafier , and without doubt to the genus Spirocera Boisd. 2. In the «Notes from the Leydeu Museum" (vol. Ill, pag. 89) I published the description of a new Psychid , Acanthopsyche Ritsemae. — The three specimens of this species (all males) were in a bad condition , and therefore I did not prepare the veins , the palps , etc. Having obtai- ned however by exchange one of these specimens, I care- fully examined it and found the species not being a Ps?/c/i^■c/, but belonging to the Liparidae (vide: Observations syno- nymiques relatives a des Psy chides , etc. par F.

Eu clonnant la description du X microcerus White, Mr. Pascoe fait observer que parmi les dix exemplaires de cette espèce qu'il avait a sa disposition il y en avait quatre qui au premier abord lui avaient paru constituer autant de types différents, mais qu'après les avoir examines plus attentiveraent il n'avait pas pu découvrir de caractères positifs pour les distinguer. Il conclut done a l'adoption d'une seule espèce répandue dans toute la Malaisie, les Molucques et la Nouvelle Guinee. Quiconque a été a même d'étudier la faune coléoptéro- logique de l'Archipel Indo-Malais et de la Nouvelle Guinee a pu s'assurer que les espèces dont l'habitat s'étend sur toutes ces contrées constituent des exceptions fort rares. On peut done a priori mettre en doute la presence d'une même espèce a Java, aux Molucques, a Celebes et a la Nouvelle Guinee, Avec des insectes a formes aussi peu con- stantes que les Prionides en general et que les Xixuthrus en particulier il est néanmoins fort difficile de débrouiller les espèces a moins d'avoir un materiel fort considerable a sa disposition. Plus heureux que Mr. Pascoe j'ai pu exa- miner plus d'une centaine de Xixuthrus et en tenant compte des differences individuelies auxquelles ils sont sujets et qui portent sur presque toutes les parties du corps, mais principalement sur la forme du prothorax, je crois pouvoir admettre les espèces suivantes: 7. X:. Microcerus White, Cat. Long. p. 40. Male. Tête aussi longue que large. Mandibules assez allongees. Prothorax en carré transversal, un peu atténué en avant. Cotes des élytres élevées.

Pattes antérieures moins scabreuses que dans l'espèce précédente , couvertes de rides ondulées desquelles s'élèvent par ei par la quelques aspérités. Femelle. Prothorax de même forme que celui du male mais comparativement plus court. Antennes un peu plus longues que Ie milieu de l'élytre , scape brillant , muni de quelques points et d'une rangée d'épines comme dans Ie male. Pattes antérieures lisses, offrant seulement quelques traces d 'aspérités. Amboine, Ceram, iles Key, Myssol. C'est l'espèce la plus grande. EUe atteint une taille de 120 m.m. et les petits exemplaires ne mesurent guère moins de 80 m.m. EUe est généralement confondue avec la X. microcerus quoique ce soit en réalité celle qui s'en éloigne Ie plus , notamment par la conformation du prothorax chez Ie male. Mr. Thomson avait signalé une espèce de Ceram, sous Ie nom de X. Anguis , mais d'une part il ne l'a pas décrite et d'autre part il l'a déclarée plus tard (Rev. Zool. 1878, p. 67) identique avec Ie X. microcerus. J'ai done cru prudent de ne pas adopter ce nom. 9. X. ^^is Thomson, Ann. Soc. Ent. Fr. 1877, Buil. p.cLxvii. Male.

Sa taille est plus petite et ne dépasse jamais 80 m.m. Il y a même des exemplaires qui ne mesurent que 50 m.m. O'est la seule espèce dont la femelle ait Ie prothorax en carré transversal comme celui du male. 10. Jt. Bufo Thomson, Rev. Zool. 1878, p. 67. Male. Cette espèce reproduit tout les caractères de l'es- pèce précédente mais elle en diffère par sa couleur plus foacée et ses antennes plus courtes, n'atteignant que les trois quarts de l'élytre. Quant a la femelle, c'est elle qui offre la dijBférence la plus essentielle puisque son prothorax n'est pas transversal et carré , comme celui du X. Axis , mais semilunaire comme celui des deux premières espèces. Sa taille est encore moindre que celle du X. Axis , et elle habite Ternate, Halmaheira et les iles avoisinantes. Le A'. Nycticorax Thomson, Ann. Soc. Ent. Fr. 1877, Buil. p. CLiv, est une espèce voisine mais encore plus petite.

Mr. Pascoe n'a décrit que Ie male. Voici en quoi la femelle se distingue de lui. Elle a la tête et Ie prothorax comparativement petits , ce dernier sans granulations, orné seulement de quelques points, quoiqu'a surface assez inégale, et muni latéralement d'épi- nes beaucoup plus fortes; les élytres sont comparativement plus larges, lisses, a ponctuation plus forte mais non con- fluente et a cótes moins apparentes ; les pattes antérieures et Ie scape des antennes sont lisses, couvertes de gros points eufoncés. C'est évidemment Ie Dysiatus melas que Laeordaire cite comme seconde espèce de Xixuthrus (Genera. VIII, p. 91). Notes from th.e Leyden IM^useuin , "Vol. "VI. 144 PRINOBIUS. Tribu des MACROTOMIDES. Genre Prlnobius Mulsant. Dans Ie » Genera des Coléoptères" Lacordaire n'a pas adopté ce genre, auquel, a l'instar de Mr. J. Thomson, il ue reconnait aucun caractère qui puisse Ie distinguer des vrais Macrotoma. Evidemment il n'a pas eu a sa disposi- tion un materiel assez considerable, sans cela il aurait été pour sur frappe de la difference réelle qui existe entre les deux genres. C'est a tel point qu'a première vue on peut distinguer Ie male d'un Prinobius de celui d'un Macrotoma. Ctiez les premiers Ie corselet et la poitrine sont finement granules , comme corrodes , et Ie prothorax est en carré trans- versal, orné d'impressions plus ou moins brillantes. Cbez les Macrotoma Ie corselet est en general brillant, fortement ponctué , trapezoidal , différent peu de celui de la femelle dont la taille est en outre a peu prés de la même dimen- sion , tandis que la femelle des Prinobius est plus petite et a un prothorax complètement différent de celui du male. Mais Ie caractère Ie plus saillant consiste dans la confor- mation du métasternum , qui, entièrement brillant et cou- vert de poils cbez les Macrotoma, est corrode et glabre chez les Prinobius males, avec un espace basal triangulaire brillant, couvert de poils et séparé du reste par un sillon OU une carène. Les vrais Macrotoma sont tous africains tandis que les Prinobius se trouvent disséminés dans tout l'ancien conti- nent et étendent leur habitat j usque dans Ie uord de l'Australie. C'est done a ce dernier genre qu'appartiennent toutes les espèces Indo-Malaises. Elles sont pour la plu- part inédites. 13. -P. Pascoei, nov. spec. Macrotoma Luzonum Pascoe, Long. Malay, p. Q(S'o. C'est a tort que Mr. Pascoe a pris cette espèce pour le M. Lxizonum qui ne se trouve pas en dehors des iles Phi- lippines. Ce savant entomologiste u'a du reste eu que de IVotes from tlie Leyden. ÜVEuseixm, Vol. VI. PRINOBIUS PASCOEI. 145 femelles a sa disposition, a en juger par la description qu 'il en donne et je suis malheiireusement dans Ie même cas. Je ne puis done que comparer les femelles des deux espèees. Voici en quoi elles se distinguent l'une de l'autre. Celle du P. Pascoei est plus petite; son prothorax est beaucoup plus fortement ponctué , comme reticule , la pouctuation ne laissant qu'un petit espace lisse au milieu ; les bords en sont beaucoup plus épineux , mais les épines sont plus courtes et l'angle postérieur est armé d'une seule épine plus longue que les autres , tandis que chez Ie Luzonum il est orné de plusieurs épines disposées en eventail ; les élytres sont plus foncées a la base; enfin Ie 3'iie article des antennes est inerme tandis que chez Ie Luzonum il est muni de longues épines. Le P. Pascoei se trouve a Sumatra , a Bauka , a Biliton et a Borneo. L'exemplaire que Mr. Pascoe indique comme venant des iles Aru doit appartenir a une autre espèce que je ne connais pas. 14. P.

S. etc. Department of Zoology , British Miisev,m. During a visit to the Leyden Museum last September I was able to examine several species of birds , which had not come under my notice during the preparation of the Vtb volume of the » Catalogue of Birds". Some of the species proved to be very distinct and I greatly regret that they have been omitted from the volume or relegated to foot-notes , as being of doubtful validity. During the whole of the time that this volume was going through the press, I was engaged in the moving of the Zoological Collections from Bloomsbury to South Kensington , and was unable to get abroad for my accustomed course of study in foreign Museums. I am sensi- ble that the value of this volume has been somewhat im- paired by these omissions , and I publish these supplementary notes , in order to supply descriptions of several species which are wanting to its pages. Alethe diademata (Bp.), Sharpe , 1. c. p. 58. Turdus diadematus , Temm. MSS. in Mus. Lugd., undè Bessonornis diadematus , Bp. Consp. I , p. 302. I had ventured to unite the species described as above with the better known Alethe maculicauda of Hartlaub , and I was JS'otes frona tlie Leyden. ]Museuxxi, "Vol. VI. 12 ■168 ALETHE DïADEMATA. pleased to find from an examination of the type in the Leyden Museum , that this identification was correct. The species is certainly an Alethe and not a Cossypha or Bessonornis^ and Dr. Hartlaub was quite right when he re- ferred the species to the former genus , though he appears not to have recognised in his Alethe maculicauda of 1861, the Cossypha diademata of his » Ornithologie West- Afrika's" of 1857. Genus Cisticola (Sharpe 1. c. p. 235). Cisticola oryziola (S. Mull.) as suspected by me (p. 240 , footnote) is C. exilis (V. & H.). The type in Leyden is in winter plumage , and the red-headed or rujiceps stage stands in the Leyden Museum under the name of C. delicatissima (Mull. Verh.). I believe, however, that the name was never published. Suya blythi, Bp. Consp. I, p. 281. This reference has been given by me as a synonym of Prinia polychroa (Cat, B. VII, p. 202). In the Leyden Museum are some birds bearing the unpublished name of Prinia leucophris Temm,, which I believe to be the types of Bonaparte's Suya blythi. The reddish brown bill points to these birds being allied to Prinia inornata , Sykes , which they further resemble in length of wing and the uniform back ; the bill , however , seems much larger. As we have not at present been able to trace all the plumages of Prinia polychroa in Java, it seems best to suppose that the birds at Leyden may be stages of plumage of the last named -species, or they may be a large-billed race of P. inornata indigenous to Java, in which case they must be called Prinia blythi (Bp.). Genus St€€chyfis^ Hodgs, (Sharpe, 1. c. p. 532). Two species require to be added to this genus and the »Key" fp, 532) will want alternation as follows: iNotes from tlie Leyden !M.useiiixi , "Vol. VI.

Following Gray, I united the Timalia striolata of Muller to T. poliocephala of Temminck. I find, on examining the types, that I was quite wrong in this identification , for 1. striolata is a very distinct species , and is in fact so closely allied to Stachyris guttata, as to be almost inse- parable from it. I had unfortunately no specimen at hand of the latter species wherewith to compare the types of T. striolata, but on comparing them with the descriptions given in the » Catalogue of Birds" (vol. VII, p. 535) I believe that the ground-colour of the two species is diife- rent, as the Sumatran bird could not be described as ))ru- fescent-brown " above. On the contrary the colour is dark sooty brown and the ovate white spots are confined to the hind neck and sides of neck.

This species appears to be very closely allied to C. striata and C. hrevicaudata , of which species I had unfortunately no specimens by me for actual comparison. From the descriptions, however, I gather that the following charac- ters must be added to the ))Key to the Species" (p. 592): c. Throat white ; under surface of body rufescent , broadly streaked with white epilepidota. The following is a description of the original specimens in the Ley den Museum. Adult male. (Sumatra: Type of species). General colour above fulvous brown , mottled with black margins to the feathers , which have also a distinct shaft-streak of fulvous on the mantle and back ; wing-coverts reddish brown , Islotes from the Ley den IMuseum, Vol. "VI. CORYTHOCrCHLA EPFLEPIDOTA. 173 the median and greater series tipped with triangular white spots , forming a double wing-bar ; primary-coverts and quills dark brown , externally reddish brown ; lower back , rump and upper tail-coverts uniform reddish brown ; tail- feathers dull reddish brown with indistinct dusky cross-bars under certain lights; head rather more dusky brown than the back , mottled with black margins to the feathers ; lores and a distinct eyebrow white, extending to the sides of the nape , the superciliary streak somewhat mottled with dusky margins; feathers in front of the eye dusky; sides of face and cheeks dull white with dusky margins, forming an indistinct moustache; ear-coverts ashy grey with whi- tish shaft-lines, the upper margin blackish, forming a broad streak below the superciliary line; throat white, with faint remains of dusky margins; remainder of under surface of body broadly streaked ; the breast and sides of body light reddish brown with longitudinal white centres to the feathers, less distinct on the flanks, which appear uniform ; centre of breast and abdomen more broadly stri- ped, the feathers being white with pale reddish margins; under tail-coverts pale reddish brown; under wing-coverts dusky brown, slightly edged with reddish brown; quills dusky brown below, paler along the inner web. Total length 4.2 inches, culmen 0.6, wing 2.05, tail 1.25, tar- sus 0.9 [Mus. Lugd.). Young female (Java). More reddish than the male des- cribed, the white tips to the wing-coverts smaller and slightly tinged with fulvous; eye-streak also less pronoun- ced and tinged with fulvous; under surface of body more rufous than in the male , the throat whitish , washed with pale rufous on the chin.

Mr. Hume suppressed the name of Turdinulus roberti (Godw. Aust. and Wald.) and added it as a synonym of T. muri- nus (S. Mull.). Both Mr. Eugene Oates and myself follow- Notes from tlie Leyden IMCuseum , Vol. VI. 174 CORYTHOCrCHLA EPILEPIDOTA. ed Mr. Hume in this identification , as it seemed to me that Blyth's description , though short , suited Turdinulus ro- herti very aptly, and at the same time it was possible for a bird to be of the same species on the mountains of Tenasserim and Sumatra. But I now believe that we were all wrong and the name of Turdinulus roberti must be resto- red to the Tenasserim species. When at Leyden I diligently searched for the specimen of Myiothera murina referred to by Mr. Blyth , and my friend Dr. Jentink assisted me in the search , but we found no species bearing the name that would answer to Mr. Blyth's descriptions. A Myiothera murina of Muller we found, it is true , but it was the Brachypteryx murina (S. Mull.) of all authors , and the Crateroscelis murina of my volume (Cat. B. VII, p. 590). The only specimens which at all answer to the descrip- tion given by Mr. Blyth are those of C. epilepidota , which also does come from Sumatra, as stated by him, while the true Myiothera tnurina , S. Mull, certainly does not. There is no specimen of Turdinulus roberti at all in the Leyden Museum. In fact the whole of Blyth's paper is somewhat confused, and it is difficult even to find out whether he is writing about birds at Leyden or in the Derby Museum at Liverpool. I believe that T'urdinus epilepidotus was the species which he intended to write about, and that he affixed the name of Myiothera murina from memory.

MALACOPTERUM ERYTHROTE. 175 whatever that M. erythrote of my Catalogue is 31. pyrrho- genys (Temm.), as indeed I hinted in the last mentioned work (p. 588, note). The types of the latter species are from Java , and it is perhaps doubtful whether the type oi M. erythrote really came from Borneo. The species will, therefore , stand as Malacopterum pyrrJiogenys (Temm.). Genus Malia, Schl. (p. 587). This genus, which I had not seen at the time of writing , is nearly allied to Mystacornis and may be separated as follows : X. Size large; tarsal envelope coarsely scutellated Malta, p. 587. (3. Size small; tarsal envelope entire. Mystacornis,i).hdl. The relationship is interesting, as shewing a link between the Avifaunse of Madagascar and Celebes.

Total length 11 inches, culmen 1.2, wing 5.2, tail 5.0, tarsus 1.9. Genus Stachyridopsis ^ Sharpe, 1. c p. 597. I have placed Salvadori's genus Cyanoderma as a syno- nym of Mixornis (p. 575), This I now find to have been an error , Cyanoderma erythropterum , the type of Salva- dori's genus, not being congeneric with Mixornis, but being absolutely the same as Stachyridopsis ^ which must consequently sink into a synonym of Cyanoderma. I entirely overlooked the shape of the nostril in the two genera; for in Mixornis the nasal aperture is ovate, situa- ted in front, while the membrane is posterior, whereas in Cyanoderma and Stachyridopsis it is superior and so swol- len , as to reduce the nasal aperture to a longitudinal , inferior, slit, a formation exactly similar to that of Sta- chyris. The form of the bill is , however, much more slen- der and pointed than in the latter genus and is much more wren-like in structure. The genus Cyanoderma , therefore will contain the fol- lowing species : 1. C. erythropterum (Blyth). 2. C. hicolor (Blyth). 3. C. rujiceps (Blyth). 4. C. rit/i/ro/zs (Hume). 5.

General colour above light rufous , more ferruginous on the crown of the head ; wing- coverts bright ferruginous, forming a conspicuous shoulder- patch; quills dusky brown, externally like the back; up- per tail-coverts like the back ; tail-feathers dingy reddish- brown with obsolete dusky bars under certain lights, and with a slightly more reddish shade on the margins; fore- head dusky blackish ; lores whitish , extending over the eye and forming an eyebrow , the hinder portion of the latter being pale ashy grey , like the ear-coverts , sides of the face and sides of neck ; cheeks rather whiter ; throat white, separated from the breast by a praepectoral collar of black ; sides of upper breast ashy grey ; centre of breast creamy white ; the abdomen , flanks , thighs , and under tail coverts pale fulvous brown; under wing-coverts and axillaries pale rufous buff; quills dusky below, pale rufes- cent along the edge of the inner web. Total length 5.2 inches, culmen 0.65, wing 2.4, tail 2.15, tarsus 0.9. Adult female. Similar in colour to the male. Total length 5.2 inches, wing 2.25, tail 2.2, tarsus 0.85. In the type-specimens the edges to the quills and tail- feathers are of about the same colour as the back ; but in some others more recently added to the collection they are rather more ferruginous, I am of opinion that in the living bird the pectoral collar is not continuous, but that there is a ring of black separating the throat from the breast, while a broad black streak occurs on either side below the hinder cheeks. The praepectoral ring is formed by black tips to the feathers , whereas the black lateral streaks are caused by the half of the feather being entirely black longitudinally. It follows, therefore, that an entire revision of the Notes from the Ley den IMusenm, "Vol. VI. 178 CYANODERMA. »Key to the Species" is necessary, as it is evident that C. melanothorax , by reason of its pectoral band , is closely allied to C. poliogaster of Hume. I propose the following re-adjustment: a. With no pectoral band .... erythropterum etc. b. With a pectoral band. x'. Band on breast black ; sides of body and abdomen pale fulvous brown poliopse. (3'. Band on breast pale olive-brown ; sides of body and abdomen grey poliogaster. Genus Alcippe (Sharpe, 1. c. p. 618). Alcippe pyrrhoptera. Napothera pyrrhoptera , Bp. Consp. I, p. 358 (1850, ex Boie MSS. in Mus. Lugd.). Macronas pyrrhopterus ^ Grray, Handl. B. I, p. 318, no. 4768 (1869). A large series of this bird and an allied species named in the Museum Napothera phaionota (Kuhl) are in the col- lection at Leyden. The last-named species is identical with Alcippe cinerea, Blyth (Sharpe, Cat. B. VII, p. 622), but I cannot find that Boie's name was ever published. A. pyrrhoptera appears to me to be a distinct species, closely allied to A. phayrii , having the ear-coverts similar to the under surface of the body in colour. It differs, however , in having the head rufescent like the back and the external aspect of the wings, tail and upper tail- coverts rufous. Notes from the Leytlen MLuseuni, "Vol. "VI.

LEMA H/EMATOMELAS. 201 NOTE XXXL DESCRIPTIONS OF NEW GENERA AND SPECIES OF PHYTOPHAGOUS COLEOPTERA COLLECTED BY Dr. B. HAGEN at Serdang (East Sumatra). MARTIN JACOBY. Cviocevin«B . Lenta hcematomelas , Lac. The Sumatran specimens before me, belong with one exception to the var. a. of Lacordaire , in which the un- derside and the antennae are entirely fulvous; in these specimens , not only the anterior legs , as Lacordaire's de- scription says, but all are of the same colour. The spe- cies seems to vary greatly in this respect, the underside, legs and antennae being either fulvous or black. I may further add to the author's description that there is a more or less distinct trace of another transverse thoracic depres- sion anteriorly in all the specimens which have come under my observation and which is frequently the case in other species from the eastern parts of the world. Lema palpalis, Lac. A single specimen of this species , which is also found ^otes from the Leyclen IMuseum, Vol. "VI. 14 202 LEMA PALPALIS. in Java aud ludia, is contained in the present collection. The shape of the palpi , which have their terminal joint distinctly swollen, distinguishes well the present insect. Lema fulvula, Lac? » coromandeliana ?, Lac. The single specimen which was obtained by Dr. Hagen agrees very nearly with the L. fulvula, which, together with many other varieties , has been united by Mr. Baly under the name of L. coromandeliana Lac. In the insect before me, the underside (with the exception of the apex of the abdomen) is black as well as the lower part of the head , the antennae (the basal joint excepted) and the tibiae and tarsi; all the rest is fulvous. So far this agrees with Lacordaire's description, the differences are however the following : the entire head is covered with close and yellow pubescence and there is a total absence of the frontal ele- vations , very distinct in L. coromandeliana (as also agreeing with the author's description) , the thorax instead of being »lisse" has 2 fine but distinct rows of punctures; without more specimens for comparison I am not able to say whether the insect before me is Lacordaire's species or a new one. Callisina integricollis , n. sp. Oblong-ovate , subcylindrical , reddish fulvous ; legs and antennae (their 3 basal joints excepted) black; thorax fi- nely punctured, sides not dentate; elytra finely punctate- striate. — Length 2 lines. Head swollen at the vertex , deeply punctured at the sides above the eyes; epistome separated from the face by a deeply punctured oblique groove, its anterior margin concave-emarginate ; jaws black ; antennae dilated and wi- dened at the terminal joints , 3 lower ones fulvous , the Notes from the Leyden JMuseum, Vol. Vl. CALUSINA INTEGRICOLLIS. 203 rest black (the 2 last joints wanting) ; thorax subcylindrical , a little broader than long , lateral margin very slightly sinuate at the middle ; surface remotely and finely punc- tured at the disk, the sides more closely and strongly punctured; a deep transverse narrow groove extends im- mediately behind the anterior margin across the disk ; scu- tellum elongate, semi-triangular; elytra finely punctate- striate , the shoulders prominent , immediately within the latter and below the base a deep depression is seen, on account of which the basal portion seems strongly raised- a very distinct tubercle is placed immediately below the shoulder, extending in shape of a short costa to the sides ; inner side of the femora stained with fulvous , armed with a minute tooth. The single specimen before me does not differ in struc- tural characters from the other 2 species of this genus , except in the entire , not dentate , sides of the thorax and in the more cylindrical shape of the latter. Aoria nigripes , Baly. This insect, of which a single specimen was obtained by Dr. Hagen , has not been previously recorded from the Eastern Archipelago, Mr. Baly's specimens having been captured at Hongkong; these specimens do not differ from the Sumatran form. Rhyparida pinguis, Baly. » ovalis ?, » I do not think that the two species described under the above names are specifically distinct, as fulvous and pi- ceous coloured specimens from the same locality are contai- ned in the present collection which I am not able to se- parate otherwise. The elytra in this species are longitu- dinally sulcate throughout, by which character the insect may be principally known, but the margin of the thoracic episternum is not concave (characteristic of Rhyparida) but Notes from the Leyden M!useura., Vol. VI. 204 RHYPARIDA PINGUIS. convex ; the insect had therefore be placed better in the genus rJiytorus Jacoby (Ann. Mus. Genoa. XX. 1884). It is possible that the species described under this name by myself is but the male form of the present insect. Abirus subrugosus, n. sp. Metallic green ; head finely and closely punctured , semi- pubescent ; antennae dark violaceous blue, the last five joints strongly dilated; thorax strongly and closely punctured; elytra finely and regularly puuctate-striate at the inner disk , strongly transversely rugose at the sides. — Length 4 lines. Head somewhat swollen , very closely and finely punc- tured; middle of the front with an obsolete longitudinal groove , sparingly covered with fulvous pubescence ; epistome not separated from the front , a little more strongly punc- tured than the latter , its anterior margin slightly concave- emarginate ; labrum metallic green ; antennae half the length of the body , the first joint metallic green , the following violaceous , last 5 joints very strongly dilated and flatte- ned; thorax transversely convex, strongly deflexed at the sides, all the angles with a distinct tubercle, surface clo- sely and evenly covered throughout with oblong deep punctures, rather more strongly impressed at the sides than at the disk ; scutellum distinctly broader than long , violaceous ; elytra subcylindrical , distinctly depressed below the base , the latter having a somewhat raised appearance, the entire inner half of their disk is finely and regularly punctate-striate , the outer portion strongly transversely strigose; these elevated strigae assume towards the apex the shape of single irregular tubercles which are placed on a slightly raised longitudinal ridge ; under surface sparingly clothed with fulvous pubescence. This species , of which but a single specimen is before me, diff'ers from A. (Dermorhytis) elegans Baly in the very regular punctuation of the inner disk of the elytra, the ]>fotes irom tlae Leyden Museum, Vol. VI.

Elytra with a single sublateral costa from the middle to the apex. Head very deeply and strongly punctured , the punctua- tion much more closely arranged at the vertex than towards the lower portion and at the former place of oblong shape ; epistome separated from the face by a deep transverse groove, the space immediately above the latter covered with coarse dark fulvous pubescence in the middle of which an oblong small tubercle is placed ; epistome broader than long , closely rugose-punctate ; labrum obscure metallic green; antennae less than half the length of the body, the first joint metallic green, the 5 following joints obs- cure dark fulvous stained with metallic green, the 5 ter- minal ones dilated, purplish blue; thorax transversely convex , the sides moderately deflexed anteriorly , the lateral margin rounded from the middle to the apex; anterior angles acutely produced ; surface impressed with deep punc- tures which are only somewhat closely placed anteriorly , the base and sides being only punctured here and there ; elytra with a deep transverse depression below the base and within the shoulders , the basal portion distinctly rai- sed and very finely punctured, rest of the surface regu- larly punctate-striate , distinctly visible to the apex ; tibiae dilated and mucronate at the apex; claws appendiculate. Closely allied to C. approximans Baly, of which the pre- sent species may possibly be a variety; the dilated joints Notes from the Leyden JVLnseum, Vol. "VI. 206 CORYNODES BASALTS. of the antennae are however black , not blue, in the allied insect, the antennae in C. hasalis are not two thirds the length of the body but much shorter and the elytral punc- tuation is very regular ; in the female insect the elytral costa begins below the middle and is abbreviated before the apex; in C. approximans it is described as extending to the sutural margin. The types of Mr. Baly's numerous species of Corynodes are contained in the collection of the British Museum, with all of which I have compared the species described here. Chrysochus Hageni^ n. sp. Oblong-ovate , convex ; entirely dark metallic blue ; an- tennae black , first joint metallic green ; thorax closely and finely punctured ; elytra closely punctate-striate. — Length 3—4^/3 lines. Head closely punctured , with a central deep longitudi- nal groove ; inner margin of the eyes surrounded by a metallic green narrow space; antennae half the length of the body, the first joint metallic green, the two following ones fulvous , the rest black ; thorax nearly twice as broad as long, the sides straight, slightly rounded in front, sur- face distinctly and closely punctured ; elytra transversely impressed before the middle , very closely punctate-striate , the punctures more strongly at the sides than at the disk, the interstices slightly wrinkled anteriorly. This species is closely allied to C. pulcher Baly, but dif- fers in its entirely metallic blue colour and in the much less coarsely and more closely punctured thorax ; the latter, in the female, is of rather more transverse shape than in the other sex.

Head smooth, impunctate; frontal tubercles in shape of a narrow transverse ridge; carina acutely raised; antennae two thirds the length of the body , the third joint scar- cely longer than the second , 3 lower ones fulvous , the rest piceous or black ; thorax transversely subquadrate , the sides straight , obliquely shaped at the posterior angles , the anterior ones acute, surface impunctate , fulvous or testaceous (in one of the 3 specimens with a metallic greenish gloss), scutellum and elytra dark metallic green, the latter very closely , finely but distinctly punctured ; posterior tibiae piceous , rest of the legs testaceous ; posterior tibiae mu- cronate , their first tarsal joint as long as the 2 following joints together. Anicera , nov. gen. Body oblong ; eyes large , convex , entire ; palpi slender , filiform; antennae elongate, rather robust, the second and third joints very short , equal , fourth joint longer than the 3 preceeding ones together ; thorax transverse , without any depressions; scutellum triangular; elytra oblong, semipunc- tate-striate , their epipleurae indistinct below the middle ; posterior femora moderately thickened , their tibiae straight , not channelled and unarmed ; posterior first tarsal joint rather longer than the two following ones united; claws appendiculate ; prosternum extremely narrow ; mesoster- num elongate , its apex pointed ; anterior coxal cavities closed. This genus seems to be an intermediate form between Chaloenus and Oxygona and having the general appearance of the latter; the structure of the antennae, in which the second and third joints are very short, will separate the present genus from either. Sutrea Baly , which also resembles in shape and coloration the genus here proposed , is at once distin- Notes from the Leyden ]>Xuseu.ca, Vol. VI, 208 ANICERA RIMACULATA, guished by the open coxal cavities and different structure of the antennae. A single species is before me. Anieera bimaculaia , n. sp. Testaceous ; upper part of the head , antennae , the breast , tibiae and tarsi black ; thorax testaceous ; elytra closely punctured, black, a rounded spot at the middle of each elytron pale fulvous. — Length 2 lines. Head impunctate at the vertex , the latter black ; frontal tubercles transverse , limited behind by a deep groove ; cly- peus triangular , testaceous 5 laljrum , jaws and palpi pice- ous ; antennae two thirds the length of the body , pubes- cent, black, the 3 lower joints testaceous, fourth joint the longest , somewhat widened towards the apex like the fol- lowing joints ; thorax of equal width , about twice as broad as long, the sides straight, the angles produced in a very short tooth , surface not visibly punctured ; scutellum black, impunctate ; elytra black , finely and closely punctured , the punctuation arranged in close longitudinal rows which get more indistinct towards the apex; at the middle of the disk of each elytron a rounded flavous spot is placed; a more or less distinct transverse depression is seen below the base; breast, tibiae and tarsi black or piceous; femora testaceous; abdomen more or less of the latter colour.

The species described here is closely allied to *S. hadia Erichs. aud S. fiava Clark , from both of which it difi"ers in its smaller size and colour of the antennae; S. nigri- cornis Baly is another closely allied species in which how- ever the third joint of the antennae is twice the length of the second; the thorax also is much more transverse and the legs are fulvous.

This species seems closely allied to S. hadia Erichs. and S. Jlava Clark , from both of which it differs in the colour of the antennae which is the same in the 12 specimens before me. From S. nigricornis Baly the species differs in its much larger size and the more distinct punctation of its elytra ; it is also found in Java. Eucyda varipes, n. sp. Rotundate-ovate , convex , obscure piceous or fulvous below ; above fulvous ; antennae black , the 3 basal and the apical joint fulvous ; legs piceous or fulvous ; thorax finely punctured ; elytra closely punctate-striate. — Length 2 lines. Head longer than broad , impunctate , the frontal tuber- cles almost contiguous and limited behind by a transverse groove; carina acutely raised; labrum piceous; palpi ful- vous; antennae about half the length of the body, the first 3 joints fulvous , second and third joint of equal length , the following slightly thickened , terminal joint elongate with a short conical appendage , fulvous ; thorax transverse , more than twice as broad as long , widened at the middle, the posterior margin distinctly sinuate at each side , the median lobe rounded and produced ; sides with a narrow margin , nearly straight ; anterior angles oblique and thickened ; surface very closely and finely punctured ; elytra closely and distinctly punctate-striate , the striae rather obsolete at the disk and near the lateral margin arranged in one or two double rows, the space in front and parallel with the lateral margin , impunctate , the lat- ter itself accompained by a row of deep punctures which are situated within a narrow but deep groove; elytral epi- pleurae broadly concave. The genus Eucyda was founded by Mr. Baly on 2 in- sects from the East, having the appearance of a species of Sphaeroderma ; in the types the eyes are extremely large , Notes from the Leyden Museum , Vol. "VI.

The present species differs rather from the others descri- bed by Mr. Baly in having the eyes smaller and the an- tennae shorter; the general shape is also less rounded and more elongate although not to a great extend ; the struc- tural characters are however all present. I may further add, that the elytral punctured striae in the allied species are much wider apart than is the case with the species descri- bed here of which 5 specimens where obtained by Dr. Hagen. Homelea , no v. gen. Body rotundate-ovate , convex ; eyes entire ; palpi thin , filiform ; antennae slender , filiform , first joint elongate , second short, third joint twice as long as the preceeding, the following more elongate; thorax narrowly transverse, anterior and posterior margin parallel, semicircular; scu- tellum trigonate ; elytra subhaemispherical , irregularly punc- tured ; their epipleurae broad , deeply concave and disap- pearing below the middle; posterior femora very slightly incrassate ; tibiae unarmed , without sulcation ; posterior first tarsal joint as long as the two following ones toge- ther; claws appendiculate ; prosternum narrow but distinct, longitudinally sulcate ; mesosternum deeply emarginate at the apex, narrowly transverse ; anterior coxal cavities closed. The general appearance of the species for which the present genus is proposed , is quite that of a species of Coccinellae ; the posterior femora are but little incrassate although more so than is the case with the Galerucinae; the inner margin of the elytral epipleurae is placed very far inwards; from the genus Acrocri/pta Baly, which re- sembles the present in shape , the filiform palpi and the shape of the posterior femora will at once separate the genus before us , which seems to be a form of transition between the Galerucinae and the present family.

I can find no other differences in the varieties but those of colour and have considered therefore all the specimens to represent the same species. Gulerttcin€B. Aulacophora cornuta , Baly. The description given of this species by Mr. Baly in the Cistula 1879 agrees perfectly with the Sumatran insects now before me; several similarly and closely allied forms inhabit Asia and the Malayan Archipelago as well as Au- stralia and the South Sea Islauds. The present species (ot which the male insect was only known to Mr. Baly and whose specimens were obtained in India) is distinguished by the peculiar formation of the face in the male and the structure of the first joint of the antennae; in the female the epistome is simple, flat and with a central elevated Notes from tlie I^eyden.

A. fla- vipes Jacoby is smaller , the last abdominal segment is fulvous and the antennae in the male are of different con- struction. Aulacopliora Q-punctata ?, Oliv. All the specimens obtained by Dr. Hagen differ from Olivier's species in having the entire base of the elytra to the extend of their first third black as well as the legs; other specimens have fulvous elytra with a black spot be- low the middle; as it is quite possible that this species is very variable in regard to colour , I have abstained in de- scribing it as new , although it may be possibly distinct from the one described by Olivier since the 10 specimens before me all agree with each other, with the exception of one or two which have the anterior legs fulvous , thus indicating intermediate degrees of colour. I am unable to determine with certainty the following species : Aulacophora spV Black ; antennae flavous ; head and thorax fulvous ; ely- tra black , finely and closely punctured ; anterior legs obs- cure dark fulvous. — Length 4 lines.

The present genus was founded by myself (Notes from the Leyd. Mus. VI. p. 69) on a species formerly included in Aulacophora, from which it must be separated on account of the prolonged elytral epipleurae ; the species here de- scribed agrees in every particular with the type except in the coloration; in the allied species the elytra are reddish fulvous , their anterior half and lateral margin being black ; ^otes from tlie ÜLieyden Museum , "Vol. VI.

Buqueti. In a specimen contained in my collection , the locality of which I do not know , all the tibiae are fulvous and the elytral tubercles black. Macrima ahdominalis , Jacoby. Of this species, which was described by myself in the Notes from the Leyden Museum (vol. VI. p. 60), I had at that time evidently female specimens only before me. In the present collection the same species is contained in both sexes ; the male insect is at once distinguished, by the longer antennae and by the posterior tibiae which are cur- ved and dilated as well as flattened at their middle, their outer edge presenting an acute ridge; nearly all the spe- cimens now before me have fulvous, scarcely punctured elytra (as in the type) but the space surrounding the scu- tellum is more or less testaceous , in other respect they do not differ. At first sight the species of this genus re- semble those of Aulacophora, from which the closed anterior cavities, continued elytral epipleurae and appendiculate claws separate them , which agrees with Mr. Baly's des- cription of the genus.

The elytra in this species have each a pale longitudinal stripe , more or less distinct , from the base to the apex ; the description given above is that of the male insect.

On account of the long first tarsal joint and closed coxal cavities , the genus proposed here is closely allied to the genus Monolepta and still more closely to Candezea Chap. This latter genus was erected on an african insect described by von Harold as a Luperode&\ from either of these genera the present is at once separated by the in- termediate dilated joints of the antennae and the shortness of their second and third joints. From Candezea it is further distinguished by the trans- versely impressed thorax. Neolepta fulvipennis, n. sp.

The present insect differs from the typical form {E. Jia- viventris Baly) in the very long fourth joint of the anten- nae, the same joint in the last named species being only double the length of the preceeding; the elytra are also here less regularly punctate-striate ; the other generic cha- racters , especially the produced metasternum and the closed anterior coxal cavities, are however all present and prove the insect to belong to the present genus, of which several species from China and India have been described by the author of the genus.

I have for the present placed this insect in Mr. Baly's genus Platyxantha on account of the closed coxal cavities, unarmed tibiae, appendiculate claws and subquadrate thorax ; the author founded his genus on male specimens in which the posterior tibiae have curious appendages and the an- tennae are difformed ; the female insects of the 3 species described are at present unknown. Notes from tbe Leyden ÜMuseum, Vol. VI. 226 PLATYXANTHA NIGRIPENNIS. There are now 4 specimens contained in the present collection which I take to represent 2 males, from Banka (v. d. Bossche), and 2 females, from Serdang (Hagen) ; in the latter the thorax is more transverse, the abdomen as usual dilated and the colour of the underside and legs variable , either fulvous or black ; other structural differences I cannot find ; should further material show that undoubted male insects are without the tibial appendages and have normal antennae but otherwise not differing from Platyxantha , as is the case with the present species , it would perhaps than be advisable for a better definition of Mr. Baly's genus , to place these insects in another or new genus. Metrioidea Fairm. seems again to differ in having the third joint of the antennae but little longer than the se- cond , while here it is about 4 times as long. Metrioidea (?), Fairm. M. Fairmaire has founded this genus on a species from the Fiji Islands ; the characters given by the author agree so well with an insect contained in the present collection, that I must refer it to this genus , which must be inclu- ded in Chapuis' 26t'i group, the Platyxanthinae ; whether the species described [here is rightly included in M.

The female , which is much larger , is probably a va- riety ; of the two males before me , one has the elytra of a dark bluish colour, the other represents a more intermediate stage in which the elytra show traces of the testaceous colour of the female with the exception of the margins which are as in the variety; no other dif- ferences are to be seen between the three specimens , which at first sight seem to represent diflferent species.

River Congo : W. Africa (v. Bemmeleu). A single specimen, JSotes from the Leyden INXuseura, "Vol. "VI, 232 PACHYTOMA SUTURALIS. This species seems to be closely allied to P. dircemoides Harold in its coloration but differs in the following par- ticulars: the head is not grooved behind the frontal tu- bercles and almost entirely black; the antennae are of different structure and comparative length of their joints ; lastly the entire underside and legs of the present species are not flavous but black. Another again closely allied species is contained in my collection : Pachytoma Batesi, n. sp. Below black or piceous ; three basal joints of the anten- nae fulvous ; head and thorax of the same colour ; 2 spots at the former and 5 at the latter black; thorax closely punctured; elytra rugose-punctate, obscure greenish black, the sutural and lateral margin testaceous. — Length 4^2 — 5 lines. The shape and colour of the elytra of this species is the same as in the preceeding and the one described by von Harold , but there are sufficient differences to distin- guish it and to consider it a distinct species. The head in the present species is closely rugose-punc- tate , testaceous , with the exception of a triangular green- ish spot at the vertex and the similarly coloured frontal tubercles; the latter are distinct but not bounded behind by a transverse groove ; the two lower joints of the an- tennae and the base of the third joint is fulvous, in other respect they resemble those of the preceeding species; the thorax is strongly and closely punctured , with the exception of a small central space near the anterior mar- gin, the disk has 5 spots of which a large one is placed at each side and three small ones in a triangle between the larger ones; the elytra are more finely punctured than in the preceeding species and have a small obscure testa- ceous spot at the middle of the base.

Head ferruginous , palpi ferruginous , annulated and tip- ped with white. Antennae dull ferruginous , delicately spotted along their upper side with white. Thorax ferru- ginous with two ill defined yellowish white spots ante- riorly. Fore- wings bright shining ferruginous , with two white spots before the fissure , one on the dorsal margin nearer to the base than to the fissure, another on the middle of the wing nearer to the fissure than to the base, a brownish spot at the base of the fissure preceded by a few brownish scales : the costal lobe clouded about its middle , but not at its base , with bronzy-brown and having two blackish streaks on the costal margin and another at the extreme apex. The central bronzy-brown shade is pre- ceded and followed by a silvery-white spot. The divided lobe is also somewhat clouded with bronzy-brown but not at its base, a silvery-white spot precedes the dark colou- ring and a second smaller one is about the middle of the upper division, a dark streak in the fringes at the apex of each division. In the pale yellowish fringes on the ]N'otes from the Leyden JMuseum, "Vol. "VI. 244 DEUTEROCOPUS RITSEM^. dorsal margin is a tuft of bronzy scales below the first fissure and another larger bronzy cloud below the second fissure.

Abdomen bright ferrugi- nous with a raised band of shining silvery scales above the middle , a conspicuous yellowish white spot preceding the anal segments. The posterior legs are bright ferrugi- nous, banded with white on the tibiae and first tarsal joint; ■with long tibial spurs also indistinctly banded, the raised tufts at their bases rather less conspicuous than in the allied D.

MYSTROPS ORIENTALIS. 245 NOTE XXXVII. DESCRIPTIONS OF TWO NEW SPECIES OE NITIDULID^ EROM SUMATRA. A. SIDNEY OLLIFP. The two species made known in the present paper were collected at Tancljong Morawa, Serdang, in N. E. Suma- tra by Dr. B, Hagen. TJie first of these is noteworthy on account of being* the only Eastern species of the sub- family Mystropinas as yet described , all the others being South American , with the exception of Mystrops dispar of Erichson, which is from Madagascar. The types of both these insects are in the collection of the Ley den Museum. 1. Mystrops orientalis, n. sp. Ovate , rather convex , shining reddish testaceous , rather closely covered with very fine yellowish pubescence. Head finely and closely punctured ; epistoma separated from the head by a moderately deep impression. Antennae pale testaceous , the club slightly darker. Prothorax at the base about twice as broad as long, much narrower in front, the sides oblique and only slightly rounded; punctuation similar to that of the head; anterior angles scarcely ob- tuse , the posterior acute and somewhat projecting. Scu- tellum rather small , extremely finely punctured. Elytra Notes from th.e Ley den IMuseutu, A^ol. VI. 246 MYSTROPS ORIENTALIS. broader than tlie prothorax, anterior and posterior angles rounded, truncate behind, inner apical angles gradually rouuded; humeral angles rather prominent; finely and irre- gularly punctured: each elytron with the apex and a mo- derately large spot at the shoulder black. Pygidium very finely punctured , densely covered with fine grey pubescence. Underside extremely finely punctured , the pubescence dense , coloured as above. Legs pale reddish-testaceous and pu- bescent. — Length 4 mm.; greatest width 2^ mm. Serdang , N. E. Sumatra (Hagen). — Two specimens. It may be found advisable hereafter to establish a new genus for the reception of this pretty species, but for the present, as only two female specimens were received, I prefer to regard it as an abberrant Mystrops. It most nearly approaches M. discoideus , Murr. •) in form ; the pro- thorax is shorter with the sides more oblique and the scu- tellum smaller , although the insect is considerably larger ; the elytra are gradually rounded behind, leaving only the pygidium and a small portion of the propygidium exposed , thus contrasting with the female of M. discoideus which has the elytra distinctly angulated; the colour and mark- ings are also entirely difi'erent. 2. Cryptarcha Mitsemce, n. sp. Cryptarcha maculata , Murray in litt., nee Reitter. Elongate-ovate, rather convex, pitchy black, shining, finely punctured and clothed with very fine yellow pubes- cence. Head rather broad, transverse, very slightly de- pressed in front, finely and irregularly punctured. An- tennae testaceous , the club darker. Prothorax about twice as broad as long , narrowed anteriorly , finely and closely punctured , only feebly emarginate in front , the sides of the emargination oblique; all the angles acute and pro- minent; sides regularly rounded; the anterior and posterior 1) Trans.

Scutellum small, exfremely finely punctured. Elytra about twice tlie length of the prothorax, narrowed behind, finely and closely punctured, ornamented with reddish-testaceous markings; humeral an- gles rather prominent: each elytron with eight rows of slightly raised pubescence; these rows of pubescence have the appearance of strife and are not very conspicuous ; the in- terstices rather broad. In the male the pygidium is den- sely covered with fine yellowish-grey pubescence. Under- side reddish- testaceous , shining , extremely finely punctured ; abdominal segments very finely and sparingly pubescent. Legs pale reddish-testaceous , the knees , tips of the tibiae and tarsi black. — Length 3 — 4^ mm. The markings on the elytra differ in the sexes of this species : in the male the elytra are pitchy black , with a rather large irregular shaped testaceous patch near the apex of each elytron ; in the female the apical patch is much larger and extends quite to the apex , which is dusky ; there are also two small circular spots placed obli- quely, one near the humeral angle and the other on the disc. Serdang, N. E. Sumatra (Hagen). — Eight specimens. After carefully comparing this insect with Mr. Reitter's descriptions of the species of the genus, I have come to the conclusion that it is allied to Cryptarcha Wallacei ') of that author, described from Batchian. It differs, how- ever , not only in having testaceous markings on the elytra , but also in its broader form and in having the protho- rax more strongly rounded at the sides. C. Wallacei is represented in the Leyden Museum by a single specimen from Saleyer determined by Mr. Reitter. Leyden Museum, September 1884. 1) Verb. Ver. Brünn. XIII. p. 119. 1875.

The Leyden Museum has from time to time been en- riched with small collections of exotic Diptera , which have neither been arranged nor determinated. In looking over these objects , I observed a great many very interesting species among them , and a more accurate examination told me , that a considerable number of them are unknown to science. In the present notes I intend to give descrip- tions of these new species , together with some observa- tions on other species already described. This first part will treat of the Diptera belonging to the old tribe Nemocera. Family Culicidae. 1. Anopheles barbirostris , n. sp. Fuscus ; thorace sublineato; haustello palpisque hirsutis ; pedibus testaceis; halteribus fiiscis ; alarum costa fusca , punc- tis cluobus niveis. — Q. Long. 5 mm. Dark brown. Rostrum and palpi longer than the head and thorax taken together, both clothed with brown scaly Notes from the Leyden JVIuseiim, ^''ol. VI. ANOPHELES BARBIROSTRfS. 249 hairs; the joints of the palpi hardly distinguishable. Tho- rax rather long and narrow, somewhat lighter coloured than the head and abdomen , quadrangularly truncated in front , with indistinct longitudinal stripes on the upper part. Abdomen with pale incisions. Legs very long and slen- der , testaceous ; femora a little enlarged towards the end , when viewed in some directions whitish at the tip. Hal- teres piceous. Veins of the wings with brown scales , which are accumulated towards the costa ; a point of snow- white scales at two thirds of the costa and a similar point near the tip ; the two furcate cells of equal length. A female from Mount Ardjoeno : East Java (Hekmeyer). The straight, projecting, hairy palpi and rostrum give this species a peculiar aspect, differing from that of our indigenous species of the genus. 2. Anopheles annularis , n. sp. Fuscus; thorace lineato • haustello nudo , nigro ; palpis hrunneis , alho-annulatis ; pedihus testaceis , tarsis alho-annu- latis ; alarum costa niveo-maculata. — Q. Long. 4,5 mm. Blackish; thorax with a dark bluish-grey dust and five longitudinal fuscous lines; pleurae light grey with black spots, arranged in longitudinal rows. Antennae with light-brown hairs; rostrum black; palpi fuscous, as long as the rostrum; the base of the first and second joints and the whole apical joint white; the two first joints covered with a dense , short , dark pilosity. Legs long and slen- der , testaceous ; anterior tarsi with a white ring on each joint; the long hind tarsi fuscous in the middle and with a white ring, wholly white towards the end. Veins of the wings with fuscous and white sales ; the costa alternately spotted with dark brown and white. A female from Mount Ardjoeno : East Java (Hekmeyer). This species may perhaps be identical with A. sinensis Wied. (Auss. Zweifl. I. p. 547). Notes from th.e Leyden ]yExiseu.m, Vol. VI. 250 TANYPUS CRUX. Fam. Chironomidae . 3. Tanypus Crux , Wied. 2.

A male from Mount Ardjoeno : East Java (Hekmeyer). The antennal plume is yellow with a brown tip. The two species of Doleschall quoted above must be regarded as synonyms of T. Crux. Doleschall describes T. parda- lis as having dark legs and unspotted wings, and T. or- natus as having a black scutellum : but the characteristic markings on the thorax and the brown tipped antennal plume are distinctly visible in his figures of the two spe- cies. In fact , in that of T. pardalis , the legs are not very dark , and what Doleschall calls the black scutellum is perhaps the black spotted metauotum , against which the narrow and pale scutellum hardly appears, but yet is more or less visible in the figure. As to the markings of the wings , in the specimen before me, they are not very clear, which may also have been the case with the spe- cimens of Doleschall so as to have led him to declare the wings unspotted. With some doubt I refer to the same species a 9 re- ceived from the same source as the above mentioned cf. The markings on the thorax are quite similar, but other- wise the female differs in many respects. It is a little smaller (2,5 mm.) ; the abdomen is wholly black and the dark markings of the posterior legs are much more extend- ed , the hind femora are almost wholly fuscous ; the wings are more darkly clouded ; in the middle the costa is brown, emitting two half bands of the same colour, the first reach- ing over the middle crossvein , the other at the end of the subcostal vein.

Reddish yellow , except the rostrum , palpi , basal joints of the antennae , and the tibiae and tarsi , which are black ; most probably the flagellum of the antennae is black also, but I am not quite sure of this as it is wanting in the single specimen before me. The head is very shining and the thorax also , though in a less degree ; on the vertex a brown ocelloid spot is present. The wings have a greyish- yellow tinge, towards the anterior margin inclining to reddish-yellow; the veins agree in colour with that of the surface. A female from Java (S. Muller). This species corresponds almost completely to the des- cription of B. ohediens Ost. Sack. (Ann. Mus. Gen.

A female from Mount Ardjoeno : East-Java (Hekmeyer). Fam. Tipulidae. Of this very extensive family the Leyden Museum has received several exotic forms , for the most part of large size. The minute ones , which undoubtedly are innume- rable in the tropical regions, are almost wholly neglected. The species of the genus Ctenophora , especially, are not rare in collections , which come to us from the East- Indies. Including the three new species , which will be described hereafter , there are at present , as far as I know , no less than sixteen described species in this genus. In order to facilitate the determination of these species , I have composed the following dichotomous table, which must be considered as a first attempt , as I had but limited materials at ray disposal, and hence was obliged to insert most of the species merely according to the descriptions.

I consider as belonging to this species three male specimens from Ha- roeka (Hoedt), Celebes (v. Rosenberg) and Am? (v, Ro- senberg). They are bright ferruginous ; the black mark- ings of the thorax are wanting and on the abdomen there is but a small black spot on the 5th and 6th segment (in the specimen from Celebes only on the 6th) ; the upper part of the genitals is also black or fuscous An- tennae a little longer than the head and thorax, reddish- yellow; the third joint with a brown tooth on the under- side; each of the following joints with four long, black and hairy appendages, which are arranged in two pairs and directed downwards ; in consequence of which the an- tennae have a very plumose appearance. Legs reddish- yellow ; femora with a black tip ; tibiae brown , towards the base with a pale yellow ring , black at the tip ; the last four joints of the tarsi blackish. Halteres reddish- yellow. Wings perfectly agreeing with my figure quoted above. 7. Ctenopliora curvipes , n. sp. Testacea; abdominis segmentis ultimis in dorso nigro- maculatis ; femoribus rujis apice nigro; tibiis tarsisque ni- gris ; tibiarum basi albo-annulata ; tibiis posticis arcuatis ; alis Jlavescentibus , apice nigricante. — Q.

Two female specimens from Ardjoeno in Java (Hekmeyer), agreeing with the description which I have given in the „Tijdschrift voor Entomologie", except that the base of the wings is more yellowish. In this species the joints of the antennal flagellum (Q) are a little dilated towards the underside , in conse- quence of which the antennae seem to be a little serrulated. 9. Ctenophora incunctans, Walk. Walk. Proc. Linn. Soc. Lond. IV. 93. 9. I refer to this species a cT from Sangir (v. Rosenberg) and a somewhat defective 9 from Tondano (Forsten). The cf agrees with the short description of Walker , the 9 with his var. /3. With regard to the female , which has only the upperside of the thorax ferruginous and which he des- cribes as the normal form , I consider it as a diiferent species (see n°. 10 hereafter). A more ample description of Ct. incunctans will not be regarded as superfluous. (ƒ.
