| Through the kindness of Mr. R. Oberthür at Rennes, France, the Leyden Museum received not long ago a specimen of a gigantic Asilid, belonging to the genus Microstylum Macq. and of oriental origin. As I cannot find in the literature of Asiatic Asilids any description applicable to it, I have no doubt that the species, notwithstanding its large size, remained hitherto unknown. In publishing it here, I name it in honour of the eminent entomologist, to whom the Museum is indebted for this interesting present. |

| In 1889 I described (Notes Leyd. Mus. XI, p. 237) a Buprestid of the genus Aphanisticus the larva of which was found at Kagob (Tegal: West-Java) mining in the under surface of the leaves of sugar-cane. I named it after its discoverer Aphanisticus Krügeri. At the same time I gave in the »Nederlandsch Tijdschrift voor Entomologie” (vol. XXXIII, p. XXII) a short notice (with figures) about the larva and the mode of life of this insect. Now I am able to describe another species of the same genus, the larva of which is found in Eastern Java (Pasoeroean) likewise mining in the leaves of sugar-cane. A few specimens of this species, which will be described in this Note under the name of Aphanisticus consanguineus, are sent to me by Dr. L. Zehntner, who is intended... |

| At the request of Mr. Ritsema I give here the description of a new Ichthyurus from Eastern Java, belonging to the collections of the Leyden Museum. The species of Ichthyurus at present known as inhabiting the island of Java are very few in number, and I have to thank Mr. Ritsema for entrusting me with the study of a very remarkable form of this highly interesting genus of Malacodermidae. |

| A species of moderate size (measuring 10—11 mm. in length) which is easily recognizable by the two approximate tubercles on the middle of the first ventral segment. Its colour passes from ferruginous brown (immature specimens) to pitchy black with purple and green tinges on the upper side; the palpi and antennae are ferruginous. The sides of the sterna are covered with very fine and short whitish setae. |

| Long. 22 mill. — La description du javanus Burm. lui conviendrait assez, mais notre insecte est notablement plus grand, non élargi en arrière, la tête est presque tronquée avec les angles obtus, finement rugueuse sur le front, à peine en avant, avec un relief transversal à peine saillant; le corselet est entièrement lisse, les angles antérieurs sont bien marqués, les postérieurs arrondis; les élytres ont chacune 9 stries profondes, très fortement ponctuées, plus faibles sur les côtés et surtout à l’extrémité, les intervalles sont assez convexes et lisses; le pygidium est couvert d’une ponctuation extrêmement fine et serrée, égale, les tibias antérieurs sont armés de 3 fortes dents. La coloration est d’un brun noir très brillant en dessus, un peu moins... |

| Deux individus du Szé-tchouen se rapportent à la description et à la figure de Redtenbacher. Mais chez l’un les expansions du corselet sont plus développés et l’angle latéro-postérieur dépasse fortement les bords latéraux en formant presque un crochet très pointu. La tête n’est pas aussi triangulaire que l’indiquent le texte et la figure, elle est plus obtuse, plus ogivale, les carènes transversales sont aussi fortes l’une que l’autre, toutes deux légèrement arquées; les élytres ont des stries à peine enfoncées et légèrement ponctuées. Malgré ces quelques differences je crois bien que cet insecte appartient à l’espèce de Redtenbacher que j’avais déjà signalée du Yunnan. L’autre individu est au contraire moins graud et moins développé, les angles latéraux... |

| Cet opuscule était en partie terminé lorsque M. Ritsema eut l’obligeance de me soumettre un Chrysochroa qu’il croyait nouveau et dont il voulut bien me confier le soin de la description. Je ne pouvais mieux faire que d’intercaler celleci dans la présente étude et de confier cette dernière aux Notes from the Leyden Museum, toujours accueillantes. Par sa distribution géographique, le genre Chrysochroa appartient à la faune Indo-Malaisienne et la majeure partie de ses espèces vit dans les nombreuses îles qui sont le joyau des Pays-Bas et constituent les plus belles colonies du monde. Il était donc tout indiqué de faire paraître mon étude dans une publication Néerlandaise et je saisis cette occasion pour remercier M. Ritsema de son offre obligeante. |

| Enclosed I send you some specimens (males and females) of an Ichthyurus-species captured by me on December 27th of last year at Poespo, about 600 M. above the level of the sea, on the slope of the Tengger Mountain (Pasoeroean Residency). These handsome beetles were flying round a young fig-tree Urostigma spec.), and, on examining the tree more carefully, I found them on the under side of the leaves. I was not able to make out what they were doing there, but I saw them stumble between the hairs of the leaves with their mandibles as it were in search of small insects, which, however, I could not detect with the naked eye. Ichthyurus flies very well, and it is especially remarkable how easily they take flight and sit down again, a fact which is very... |

| Nous diviserons ce travail en trois parties distinctes. Dans un premier chapitre, nous allons publier le texte, inédit jusqu’à ce jour, de notes manuscrites laissées par Kuhl et van Hasselt et accompagnées d’aquarelles également inédites, concernant les Hirudinées des Indes néerlandaises. Dans un second chapitre, nous étudierons les Hirudinées d’Extrême-Orient qui font partie des collections du Musée de Leyde. Un troisième chapitre sera consacré à la révision de quelques Hirudinées de provenance variée. Un certain nombre d’espèces énumérées ci-dessous ont déjà été étudiées par nous dans d’autres publications. Afin d’éviter d’inutiles redites, il nous semble donc hors de propos d’en répéter ici la diagnose, à moins que nos récentes observations ne nous... |
