Die geringen Kenntnisse, welche wir über die geographische Verbreitung der Hymenopteren besitzen, veranlasste mich während meines Aufenthaltes auf der herrlichen Insel dieser Thiergruppe meine besondere Aufmerksamkeit zuzuwenden. Weiteres Materiale wurde mir durch die Güte des Herrn H. Gätke, Secretär des Gouvernors der Insel, zugebracht, der als Ornithologe allbekannt und berühmt, auch den Insecten seine Aufmerksamkeit zugewendet und namentlich an Käfern und Schmetterlingen sehr umfangreiche Sammlungen zusammengebracht hat. Es liegt mir klar, dass dieses Verzeichniss nur ein Bruchtheil der voll ständigen Hymenopteren-Fauna der Insel ist; doch hat vielleicht auch dieser namentlich im Zusammenhalte mit der Fauna von Spiekerooge, die allein biś …

Die im Folgenden niedergelegten Bemerkungen und Notizen entspringen zum grössten Theile der Durchsicht des reichhaltigen Materials dieser Gattung im k. k. zoologischen Museum in Wien, dessen Benützung mir vom Herrn Director Dr. Steindachner freundlichst gestattet wurde und wobei ich von den Herren Josef Rogenhofer, Custos, und Ludwig Ganglbauer, Adjunct, in der zuvorkommendsten Weise unterstützi wurde; auch das im raschen Aufblühen begriffene National-Museum in Buda-Pest, dessen Adjunct, Herr Al. Moscary, mir die Durchsicht der vorliegenden Gattung – und vieler anderer – in liebenswürdigster Weise ermöglichte, lieferten den Stoff zu denselben: sei obgenannten Herrn mein bester Dank auch öffentlich ausgesprochen!
