Abstract
Twenty-two species of Scolytidae (including one new species), and one species of Platypodidae are recorded from the Cook Islands and Niue in the South Pacific, and a key is given to all species. Corrections are made to earlier records from the islands. Xyleborinus perexiguus (Schedl) comb. n. is transferred from Xyleborus. The faunal composition, breeding habits and geographical distribution of the species are discussed and related to those of other islands in the Pacific. Many species have probably been introduced by man. In the absence of a major timber industry, the species are likely to be of minor economic importance.
