Twenty species of Scolytidae and seven species of Platypodidae are described from fossiliferous amber originating from the Dominican Republic. The amber is estimated to range in age from 23 to 40 million yr old or Lower Miocene to Upper Eocene. The new species of Platypodidae are Cenocephalus antillicus, C. antiquus, C. biconicus, C. exquisitus, C. senectus, C. spinatus, and Tesserocerus primus. The new genera and species of Scolytidae are Phloeotribus antiquus, Cladoctonus angustostriatus, C. ruber, Paleosinus (n. gen.) fossulatus, Protosinus (n. gen.) hispaniolensis, Cnemonyx priscus, Scolytus poinari, Pycnarthrum senectum, Micracites (n. gen.) squamifera, Dryomites (n. gen.) incognitus, Hypothenemus avitus, Corthylites (n. gen.) bicolor, Gnathotrichus fossor, Microcorthylus antiquarius, Paleophthorus (n. gen.) bispinus, Pityophthorus antiquarius, P. aphelofacies, and P. temporarius. All these species are illustrated here by photographs or line drawings or by both. Types of the three species of Platypodidae described by Schedl (1962) from Mexican amber were examined. Notes concerning the type condition are given for each species.
