Summary The authors have studied excretory globules in the Malpighian tubes ofMelipona larvae. By means of histochemical methods for fats, micro-interferometry and electron microscopy, glycerides surrounded by a lipoprotein or phospholipid layer were tentatively recognized in the globules. They resemble in composition the brochosomes reported in Homoptera and are found in the cell borders and in the lumina of the tubes. Yellow-green autofluorescent granules are seen within the cells, in the honeycomb borders and in the lumina of the tubes. It was not determined whether there are two distinct kinds of globules or only one kind in different physiological stages.
