Some galls from the island of Enggano

The island of Enggano is the most southern of a series of islands situated parallel to the Western coast of Sumatra. In 1936 the island was visited by Dr. W. J. LüTJEHARMS, who stayed there from the end of May to the beginning of July collecting materials for the Herbaria at Buitenzorg and Leiden. During this excursion he also collected some zoocecidia, which were sent to me for classification by the Director of the Rijksherbarium, Leiden. The collection consists of 16 galls on various plants; many of them were already known as occurring in other parts of the Malay Archipelago; others are new, these are marked with an asterisk. A collection of 16 galls is actually to small to give insight into the wealth of galls of this tropical island; so far, however, nothing was known about the galls of the island, and since it is unlikely that the place will before long again be examined as to its galls, I deemed it worthwile to describe this small collection.
