Dedicated to Mrs. W.S.S. van Benthem Jutting Scale insects from the Netherlands Antilles

Van Hall (1905) mentions Chionaspis citri as a pest of orange trees in Curagao; this insect is at present known as Unaspis citri (Comstock, 1880). Further he found in Curacao and Surinam Mytilaspis citricola; its present name is Lepidosaphes beckii (Newman, 1869). Lepidosaphes gloverii (Packard, 1869) and Pinnaspis buxi (Bouche, 1851) are also mentioned. Chionaspis minor was found on cotton, Ricinus, and oleander, but not on Citrus. Chionaspis minor Maskell, 1884, often reported from tropical Amer-ica, is a misidentification of Pinnaspis strachani (Cooley, 1899), a polypha-gous insect, known from the West Indies, the Bahamas, Florida and Mexico. All the above mentioned insects are common in the West Indies. For microscopical details of these insects see Ferris ' Atlas, vol. I—IV (Pinnaspis strachani was erroneously described by Ferris as Pinnaspis temporaria n.sp.; see Ferris & Rao, 1947). Versluys (1907) mentions a Ceroplastes sp. from Curacao which is in-jurious to dividivi (Caesalpinia coriaria Willd.) It forms yellowish white rings of a waxy substance around the young twigs. Small animals, with a watery red body-fluid, were observed in this waxy substance, separated at a regular distance from each other. In the beginning of September young specimens were found which had already secreted a small quantity of wax. The inhabi-To the Netherlands ' Antilles belong the islands of Curacao, Aruba, and Bonaire, near the coast of Venezuela, further among the Lesser Antilles Saba, St. Eustatius, and half of St. Martin (the other half is French territory). As far as I know, only twice a note has been published on the scale insects of these islands. Dr. C. J. J. van Hall, who was appointed in 1903 to In-spector of Agriculture in the Dutch West Indies, published a short bulletin on scale insects damaging orange trees in 1905. Dr. H. J. Veth wrote a short article on Rhynchota in the "Encyclopaedic van Nederlandsch West-Indie&quot
