The genus Diomorus ,walker has the mesepisternum deeply incised above the middle and will therefore have to be placed in the Toryminae, where it can be separated from the other genera by the tooth on the hind femora. In his classification of the Chalcidoidea, Dr. Ashmead has used the presence or absence of teeth on the hind femora as a secondary character to separate the Toryminre and the Monodontomerinre. This will have to be dropped or at least modified to show the above exception.

De studie der Hymenopterenfauna van België werd tot dusverre door onze entomologen sterk verwaarloosd, en ook elders in Europa telt dit onderdeel der entomologie niet genoeg beoefenaren. In Nederland zelf, waar zekerlijk op gebied van natuurstudie over gebrek aan werkzame handen niet kan geklaagd worden, is de kennis der inheemsche Hymenoptera zeer onvoldoende. Waar J. Th. OUDEMANS (1) het aantal Nederlandsche soorten op 4000 durft schatten, staan er echter niet meer dan 1775 als inlandsch geboekt. Hier te lande is de toestand nog veel min bevredigend en het is hoog tijd dat een groot aantal liefhebbers het onderzoek dezer belangwekkende …

In dem Reisewerke Expedition scientifique de Moree hat Bralle im Jahre 1832 mehrere neue Halictus-Arten beschrieben, deren Deutung bislang noch nicht wieder versucht wurde. Die Typen dieser Spezies, welche im Museum d'histoire naturelle de Paris aufbewahrt werden und mir von Herrn R.. du Buysson zur Untersuchung gütigst anvertraut wurden, sind leidlich gut erhalten, so dass sie identifiziert werden können.
