The following species have been reported from the Netherlands’ Antilles: Margarodes formicarum Guilding, collected in 1884 or 1885 by Prof. W. F. R. Suringar in Curaçao; specimens in the State Museum of Natural History at Leiden. Protortonia cacti (Linn.), collected in 1756 by Daniel Rolander in St. Eustatius, and described by Linnaeus (1758) and de Geer (1776). Protortonia crotonis n. sp. from Bonaire. Icerya purchasi Maskell from Curaçao. Orthezia praelonga Douglas, common in Curaçao and Aruba. O. insignis Browne is in our collection only represented from St. Eustatius. Coccus sp.

Pulvinaria sp. from Aruba; resembles P. mammeae Maskell, but different. Coccus sp. from Thespesia populnea (Malvaceae) in Aruba; material too scanty for identification or description.

Antonina graminis Maskell on the rootcollar of Fimbristylus spathacea (Cyperaceae) in Curaçao. Eriococcus curassavicus n. sp. is probably identical with or closely allied to E. tucurincae Laing from Colombia; all female and male stages of the Curaçao-species are described.

Acutaspis scutiformis (Ckll.), Aonidiella orientalis (Newst.), and Lepidosaphes alba Ckll. frcm Aruba. Unaspis citri (Comstock), Lepidosaphes beckii (Newman), and L. gloverii (Packard) are common on Citrus in Curaçao. Diaspis echinocacti (Bouché) from Opuntia in Curaçao. Pseudaulacaspis peutagona (Targ. Tozz.) from Aruba and St. Eustatius. Hemiberlesia diffinis Newst. was found on dividi in Curaçao, Pinnaspis strachani (Cooley); label not legible, but certainly from the Dutch Antilles; this species is already reported by VAN HALL (1905) from Curaçao.
