Continuing the enumeration of the Lepidoptera from Simalur and neighbouring islets, collected by Mr. Edw. Jacobson, I have to notice only one new form of Cethosia and of Acca among a number of 16 species of Nymphalidae. The Satyridae were represented by one species and the Morphidae by two. According to a letter of Mr. Jacobson the Lepidopterous Fauna of the named islands must be much richer than the collection brought together by him, let think, because it was very difficult to capture the very high flying butterflies. In some cases Mr. Jacobson has made use of his rifle, what is very well to see in the specimens.
