| Bevor ich mit der Bearbeitung des dritten genus der Parnassiinae beginne, muss ich noch einmal einen Rückblick auf die bereits erfolgte Revision werfen. Ich habe schon früher erwähnt, dass meine Publikationen durch Aufführung aller in meiner Sammlung befindlichen Exemplare einen wissenschaftlichen Katalog dazu darstellen sollen. Da ich inzwischen die Bestimmung getroffen habe, dass meine Sammlung in den Besitz des Rijksmuseum van Natuurlijke Historie, Leiden, übergehen soll, hat dieses mich ersucht, sein eigenes Parnassius-Material in meine Sammlung einzugliedern. Ausserdem habe ich mehr als 20 000 Parnassier aus collection R. Oberthür erwerben können, die mein schon vorhandenes Material wertvoll ergänzen. Ich beabsichtige deshalb auch, nicht nur... |

| Dr P. Vermeulen, Amsterdam, who had obtained the 1955 grant of the Netherlands Buitenzorg Fund went via India, where he spent a month above Darjeeling, to Bogor; he also paid a visit to Queensland, his chief interest being the study of Orchidaceae. In returning he made a trip in Central Sumatra with Dr Meijer; he arrived in Holland end Dec. 1956. Mr L.L. Forman, Kew, who was granted a year leave for work at the herbarium Bogoriense, Bogor, made various trips in Indonesia, collecting in W. Java, Bali, North-east Celebes, and joining Dr Kostermans on a forest survey in East Borneo. |

| Trees. Leaves estipulate, alternate, scattered, simple, oblong to obovate, petiolate, tertiary nerves transverse, often numerous, always faint. Inflorescences many-florous, fasciculate on brachyblasts which are inserted in the axils of leaves or their scars, rarely in those of stout petiole-like bracts. Flowers 6(—8)-merous. Sepals 6(—8), spirally arranged or pseudo-cyclical. Corolla exsert, lobes 6(—8), as long as or longer than tube. Stamens 6(—8), inserted just or well below the corolla-throat, epipetalous. Staminodes 6(—8), episepalous, inserted in the throat. Ovary 6(—8)-celled, borne on a short stout gynophore, disk infundibuliform at apex of gynophore, more or less connate with the basal (fertile) part of the ovary, the whole (except style)... |

| Op de berm van de grote weg vlak bij het grenskantoor van Reusel (N.Br.) vond ik in Augustus 1955 een vrij groot aantal exemplaren van een Tragopogon, die ik niet thuis kon brengen. De grote hoofdjes op aan de top sterk verdikte stelen deden me aan T. porrifolius denkens, maar de weinige nog aanwezige bloemen waren helder geel, als hij onze gewone T. pratensis. Ik overwoog of ik misschien met een kruisingsproduct van T. porrifolius en T. pratensis te doen had, maar dat was toch niet waarschijnlijk. Bastaarden van deze twee soorten vertonen altijd een intermediaire bloemkleur. Een oplossing werd niet gevonden, omdat de mogelijkheid van een voor Nederland nieuwe Tragopogon niet in me opkwam en er dus geen buitenlandse flora werd opgeslagen. Toen ik echter... |

| The present paper is the result of an examination of some type specimens in the Brussels Museum, collected by G. Semper in the Philippines and described by Friedrich Brauer in 1868; it includes also a discussion of one species recorded from these islands by Edm. de Sélys Longchamps in the last part of his "Synopsis des Agrionines", in 1877. These were rendered accessible to study during my visit to Brussels in June, 1938, by Mons. Antoine Ball, at that time entomologist of the Musée Royal d'Histoire Naturelle. Through his kindness I was permitted afterwards to borrow the types for further study and to keep them for almost twenty years. This enabled me to make comparisons with certain species included in a splendid collection of Philippine dragonflies in... |

| For a long time, investigation of the fauna of Suriname encountered great difficulties. These included: great abundance of species; inaccessibility of the territory concerned; lack of zoologists on the spot, and little interest in Neotropical material on the part of Dutch biologists. Moreover, the practice of this branch of science has depended on the initiative of private individuals, the result being that no definite programme has been followed. Owing to these circumstances investigation of the zoology of Suriname has lagged far behind investigation of its botany and geology. |
