The Stagbeetle described in the following lines and belonging to the genus Metopodontus of the subfamily Cladognathinae is very interesting by having five pubescent leaflets in the clava of the antennae. In all other known species of this subfamily the number of these leaflets is three. This is, as far as I know, the second example of an inconstant number of leaflets in the species of one and the same genus of the Lucanidae Lucanus and Metopodontus). In coloration as well as in general form the new species, for which I propose the specific title spectabilis, resembles Metopodontus cinctus Montr.

A Javan species of the genus Adelotopus Hope (Coleoptera: Carabicidae)

Ano: 1912

URL: http://www.repository.naturalis.nl/record/508652

The Leyden Museum has recently received a small collection of Coleoptera from the island of Java, brought together and presented by Mr. Edw. Jacobson. Among these beetles I found a specimen of a species of the genus Adelotopus Hope, belonging to the interesting family of Pseudomorphidae (Carabicidae), which species certainly has not yet been described. I am acquainted with the description of only two other species of Adelotopus out of Australia, viz. Adelotopus collaris Waterh.¹) from Siam and Adelotopus papuanus Gestro ²) from Papuasia. A third species, described by Waterhouse (l.c.) under the name of Adelotopus marginatus and originating from Java, does not belong to the quoted genus but is synonymical with Cryptocephalomorpha Gaverei Rits. ³) from Java...

A new African Helota-species

Ano: 1909

URL: http://www.repository.naturalis.nl/record/508683

Allied to H. guineensis and Sjöstedti. Recognizable by having four black spots in the fulvous basal half of the elytra (two on each elytron), which spots are by two and two united posteriorly by an infuscation of the 4th interspace. Length 14,5 mm. — Elongate, depressed, shining; fulvous, the head with mandibles (the throat excepted), a broad streak along the middle of the pronotum (anteriorly as broad as the neck), the basal and lateral edges of the pronotum, the scutellum, and the basal edge and larger (apical) half of the elytra black, the latter with a faint bronze hue; the fulvous basal portion of the elytra shows four black spots, two on each elytron: the larger, foremost one between the 3rd and 4th striae, the smaller hindmost one between the 5th...

A new African Myodites-species

Ano: 1913

URL: http://www.repository.naturalis.nl/record/509358

Length 5 mm. — Black; the plumose antennae, the anterior femora, and the tarsi (the large basal joint excepted) pale ochreous, the middle portion of the mandibles, the apical half of the anterior tibiae, and the middle portion of the intermediate femora somewhat darker; the tip of the flabellae of the antennae infuscate; an indistinct brownish subtransparent spot on the basal half of the inner margin of the elytra; wings hyaline with a transverse dusky band just before the apex; the costal nervures alternately pale ochreous and dusky. Head and thorax opaque in consequence of a very dense punctuation, covered with a short grayish pubescence; the vertex elevated, obtusely conical; the pronotum with three small smooth spots forming an isosceles triangle which...

A new genus and apparently new species of Rhynchophorous Coleoptera

Ano: 1890

URL: http://www.repository.naturalis.nl/record/509462

In the following lines a very interesting new genus of the group Rhynchophoridae will be established. A single male specimen, from the Upper Mahakam (Borneo), has been found in a small collection of natural history objects, presented to the Leyden Museum in December of last year by Mr. Kampmeinert. The species is dedicated to the donor. The nearest ally of this new genus, for which I propose the name Mahakamia, is Macrocheirus Schönh. The characters by which the two genera are differentiated in the male sex (the female sex of my insect is as yet unknown) are very conspicuous, as will be seen from the following table.

A new genus and species of the Hymenopterous family Larridae

Ano: 1913

URL: http://www.repository.naturalis.nl/record/508477

Head transverse, much wider than the thorax, emarginated behind at the vertex, swollen behind the eyes; face distinctly prominent, provided with various depressions, the angles below the eyes angularly produced; eyes strongly divergent (making the face much wider beneath than above), large, narrowing towards the mandibles, the inner orbit straight; only one well developed ocellus; antennae filiform, inserted just above the base of the clypeus, the scape a little enlarged and compressed at its apical twothirds, a little longer than the first and 2nd joints of the flagellum taken together, the 3rd and 4th joints of the flagellum distinctly notched at the extreme base, the 5th very faintly so, the 2nd to 10th gradually decreasing in length, the 11th or apical...

A new genus of Calandrinae

Ano: 1884

URL: http://www.repository.naturalis.nl/record/508626

Having received from Mr. A. L. van Hasselt of Padang Sidempoean, among some other interesting beetles from Sipirok (North West Sumatra), a couple of a beautiful Calandrid of the group Rhynchophoridae, viz. Macrocheirus spectabilis Dohrn, I carefully examined the materials of this group in the Leyden Museum, and this examination convinced me of the necessity of dividing Schönherr’s genus Cyrtotrachelus in two genera. The following table will clearly show the distinctive characteristics of the genera of the first division of Lacordaire’s group Rhynchophorides (Genera des Coléoptères. Tom. VII. p. 271): a. Elytra distinctly narrowing backward, conjointly emarginate at the end.

A new genus of the Cetonid group Macronotidae

Ano: 1891

URL: http://www.repository.naturalis.nl/record/508865

This genus must be separated from the genus Chalcothea such as it has been hitherto defined by myself, in consequence of the distinctly margined sides of the pronotum in both sexes, and of the different conformation of the tibiae in the male: the anterior tibiae of this sex being nearly straight on the inside, the intermediate ones formed nearly as the anterior tibiae in Chalcothea (sens. restr.), the posterior ones provided on the inside of the base with a strongly compressed and irregularly impressed appendage, which extends a little behind the tip of the tibia itself; moreover the undersurface of the middle-, and especially that of the elongate hind-tarsi is rather densely covered with elongate hairs. These characteristics are derived from specimens...

A new Helota from West-Java

Ano: 1882

URL: http://www.repository.naturalis.nl/record/509030

Allied to Helota Feae Rits. from Burma and Vandepolli Rits. from Borneo, but differing from both in the pale colour of the antennae, in the more prolonged apices of the elytra and in the larger size of the yellow elytral spots. From Feae it is moreover at once distinguished by the want of the reddish testaceous lateral streaks on the pronotum and by the regularly rounded apical ventral segment. From Vandepolli it differs by the flavous lateral streaks of the prosternum and by the flavous basal half of the claw-joint of the tarsi Length 14,5 mm. — Shining; rather narrow, elongate, narrowed in front and behind; dark bronze above, here and there with a strong violet gloss; the antennae and the extreme anterior angles of the pronotum testaceous; the four...

A new Helota-species from Kondué (Belgian Congo)

Ano: 1893

URL: http://www.repository.naturalis.nl/record/508449

This new species belongs to the group of guineensis, Sjöstedti and africana 1) but is nearer to both the former than to the latter, having in the female-sex the apices of the elytra pointed, not obliquely truncate between the 3rd interstice and the suture. It differs however in the male-sex from guineensis and Sjöstedti (the ♂ of africana is not known) by the absence of the small hairy spot on the middle of the basal ventral segment. Moreover it differs from Sjöstedti by the situation of the black spot in the fulvous basal half of the elytra: in Sjöstedti as well as in africana (guineensis is unspotted) this spot lies nearer to the basal margin of the elytra than to the front border of the black apical half (consequently in the basal half of the fulvous...

A new Helota-species from Sumatra

Ano: 1910

URL: http://www.repository.naturalis.nl/record/508621

The species described in this Note and dedicated to the late Dr. E. Candèze of Glain near Liege is very interesting necessitating the establishment of a new section in my Synopsis of the species of this genus 1). It belongs to the division I (base of elytra coloured as the apex), A (elytra with four convex flavous spots), b (pronotum finely and evenly punctured, without raised patches), but it has the prosternum neither entirely fulvous (α), nor fulvous in the middle with the lateral portions metallic green (β): in the new species the prosternum is entirely of a dark metallic green colour.

A new Javanese species of the Buprestid genus Aphanisticus, Latr

Ano: 1899

URL: http://www.repository.naturalis.nl/record/509376

The nearest ally of this species will prove to be A. paradoxus H. Deyr. from the island of Makian (Ann. Soc. Ent. Belge. VIII. p. 223, and p. 227, pl. 4 fig. 20). It has a length of about 3—3 1/2 mm, and is of a blackish bronze colour, bright bronze on the head and pronotum. — The whole insect is covered with an extremely fine and dense sculpture which is only visible with the aid of a lens of strong power.

A new Longicorn beetle

Length 17½ mm. — Strongly resembling E. nigritarsis Pascoe ¹) of which I have a male specimen before me ²), but differing from it in the following characteristics: the new species is somewhat broader; its 3rd antennal joint is slightly longer, more slender, more distinctly incurvate and covered all over with a pubescence of a pale ochraceous colour ³); the 4th joint is more strongly swollen at the tip, and the 5th joint is thicker and consequently more strongly contrasting with the 6th; the prothorax becomes broader towards the base, and the scutellum is strongly transverse; finally the two basal joints of the tarsi do not show a black but an ochraceous pubescence. Each elytron is faintly notched at the end in an oblique direction which gives the apex of...

Resembling, in general appearauce, Phemone cordiger Rits. ¹) from Sumatra, but easily distinguished by the different arrangement of the white lines on the elytra. Length 12,5 mm. — Black, subshining, covered with a very delicate pile which is dark on the upper surface of the insect, bright grey, however, on the undersurface and legs.

A new Longicorn beetle from Sumatra

Length 38 mm., breadth at the shoulders 14 mm., length of the antennae 37 mm. — Black, covered with a grey pubescence which is wanting on the declivous front portion of the shoulders and which is very delicate on the legs; the antennae sooty black, the apical third of the elytra narrowly margined laterally with the same colour, the extreme tip of the apical ventral segment likewise black. Head subquadrate in front, underlobe of the eyes large, rounded; face between the eyes rather narrow, higher than broad, slightly convex in a longitudinal direction, divided longitudinally by a groove which has the impressed median line at its bottom. Antennary tubers subapproximate; antennae slender, as long as the body, the 6 or 7 basal joints thinly fringed beneath;...

A new Lucanoid beetle from Java

Ano: 1906

URL: http://www.repository.naturalis.nl/record/509339

In a consignment of beetles, lately received from Mr. J. D. Pasteur and brought together by himself in Western Java (Mt. Poentjak, on the frontier between the districts of Buitenzorg and Preanger), I found among a fine series of Cladognathus giraffa Oliv. a specimen which was at once distinguished from the others by its more slender mandibles which were regularly curved downwards, and by the rounded, not obliquely truncate anterior angles of the prothorax. A more careful examination of this specimen showed me clearly that it had nothing to do with Cl. giraffa but that it was a very close ally of the interesting Prosopocoelus decipiens Parry ¹) from Malabar. The Javanese species is certainly undescribed and I propose to call it after its discoverer:

A new Myodites from Liberia (Coleoptera: Rhipiphoridae)
