Dec. 26. 1934, Author leg. - Also reported from Borneo, the Malay Peninsula (Pahang), and the Riouw Archipelago (not " Kiour " as stated by Selys). My specimens were taken along a very small muddy brook, flowing through secondary forest, near the coast; the ♀ was also seen, but I failed to capture any. It is a robust insect. differing in some respects from a small series in my collection from W. Borneo. which are, I think. racially distinct from Sumatran specimens, More material of the type locality (" Malacca "?) is needed to ascertain the validity of subspecies, The Lampoeng series will be described at some other place.
