The list of Cetoniidae enumerated hereafter is the result of an entomological trip made during the months April and May 1889. The collections, which are in the possession of Mr. Neervoort van de Poll, are chiefly made in the following localities, viz. Belihul-Oya on the southern slopes of the central mountains; Wadduwa near the coast, south of Colombo; Nalanda on the way to Trincomalee, on the northern slopes of the central mountains, whilst several of the more common insects were obtained in the immediate vicinity of Colombo. Generally Cetoniidae are insects of rare occurrence on flowers and foliage. The common Glycyphana versicolor F., however, was taken very abundantly by native boys in the ancient cinnamon gardens near Colombo.
