Description: Among some coccids from Indonesia, received from Dr. L. G. E. KALSHOVEN, four large specimens were found which by their well developed ovisac showed some resemblance to Icerya purchasi MASK. After comparing the specimens with the photographs in MORRISON’S Classification of the Margarodidae (1928) it appeared, however, that the wax covering of the body was more alike that of Walkeriana floriger (WALKER). The old pinned specimens were not labelled, but Dr. KALSHOVEN remembered that they had been collected by Prof. ROEPKE on „tjemara” (Casuarina). Upon inquiry Prof. ROEPKE informed me that in 1910 he had collected a giant coccid on old stems of Casuarina Junghuhniana MIQ. in the Tengger Mts. (East-Java). The specimens were found on trees near the last bend of the road leading to Tosari, a well-known health-resort at an elevation of about 1750 m, where Europeans often used to spend their holidays. Some specimens had been sent to Mr. E. E. GREEN in Ceylon who replied that it was a species of Walkeriana, but that he wanted the larvae for a description of this new species.

Description: The following species have been reported from the Netherlands\xe2\x80\x99 Antilles: Margarodes formicarum Guilding, collected in 1884 or 1885 by Prof. W. F. R.\nSuringar in Cura\xc3\xa7ao; 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 Cura\xc3\xa7ao.\nOrthezia praelonga Douglas, common in Cura\xc3\xa7ao and Aruba. O. insignis Browne is in our collection only represented from St. Eustatius.\nCoccus sp. (not C. agavis Towns. & Ckll.) from Agave in Cura\xc3\xa7ao and St. Martin. Suissetia oleae (Bern.) from Cura\xc3\xa7ao and St. Eustatius. Saissetia coffeae (Walker), syn. S. hemisphaerica (Targ. Tozz.) from Cura\xc3\xa7ao and Aruba. Ceroplastes caesalpiniae n. sp. from dividivi (Caesalpinia coriaria) in Cura\xc3\xa7ao. This Ceroplastes is already mentioned by VERSLUYS (1907) as a pest of dividivi, but it seems that the species has not yet been described. Ceroplastes magnicauda n. sp. from Cura\xc3\xa7ao; not identifiable from available literature. Pulvinaria urbicola Ckll. from Cura\xc3\xa7ao and St. Martin. 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.\nDysmicoccus brevipes (Ckll.) from Bonaire. Ferrisiana virgata (Ckll.) and Phenacoccus solani Ferris from Cura\xc3\xa7ao. Antonina graminis Maskell on the rootcollar of Fimbristylus spathacea (Cyperaceae) in Cura\xc3\xa7ao. Eriococcus curassavicus n. sp. is probably identical with or closely allied to E. tucurincae Laing from Colombia; all female and male stages of the Cura\xc3\xa7ao-species are described. Asterolecanium pustulans Ckll. from Cura\xc3\xa7ao. Conchaspis angraeci Ckll. has been collected in Cura\xc3\xa7ao by G. E. Bodkin.\nAspidiotus destructor Sign, from Bonaire. 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 Cura\xc3\xa7ao. Diaspis echinocacti (Bouch\xc3\xa9) from Opuntia in Cura\xc3\xa7ao. Pseudaulacaspis peutagona (Targ. Tozz.) from Aruba and St. Eustatius. Hemiberlesia diffinis Newst. was found on dividi in Cura\xc3\xa7ao, Pinnaspis strachani (Cooley); label not legible, but certainly from the Dutch Antilles; this species is already reported by VAN HALL (1905) from Cura\xc3\xa7ao.\nThe 4 new species, Eriococcus curassavicus, Protortonia crotonis, Ceroplastes caesalpiniae, and C. magnicauda are described above.\nAn aphid from Bonaire was identified by Mr. D. Hille Ris Lambers as Aphis nerii Fonsc., and an aleyrodid from Cura\xc3\xa7ao by Miss Louise M. Russell as Aleurotrachelus trachoides (Back).

Description: Filippia orientalis n.sp. can be recognized by the following characters.\nThe adult female has next to chisel-shaped spines around the margin of the body 4 such spines on the outer side of the anal plates (fig. 11). The adult male has only one long seta (about 250 \xce\xbc) in the glandular depressions which produce the caudal wax-tails. The first stage larva is provided with long stigmatic spines (ca. 60 \xce\xbc) and slender conical spines along the margin of the body (fig. 19). The second stage larva has chisel-shaped spines around the margin of the body like the adult female (fig. 22). On the anal plates only the discal and the apical seta are chisel-shaped, the 2 setae on the mesal side of the plate have the usual shape (fig. 20).\nTypes in the Zoological Museum at Amsterdam, of second stage larvae, prepupae and pupae in the Museum of Natural History at Leiden.

Description: New Guinea is next to Greenland the largest island in the world; its area is about 785000 sq. kilometers (with adjacent islands ca. 806000 sq.kms). It lies within the tropics, quite near the equator, and is largely covered by a luxuriant vegetation, so that a rich fauna of scale insects may be expected, though extremely little has been published on this subject.\nIn FERNALD\xe2\x80\x99S catalogue with supplements (1903\xe2\x80\x941915), and in the Zoological Record for the years 1915\xe2\x80\x941957, only 4 new species are reported from New Guinea, viz. Myxolecanium kibarae BECCARI (FERNALD No. 1005), Aulacaspis major RUTHERFORD, Ceroplastes murrayi FROGGATT, and Steatococcus samaraius MORRISON (Zool. Ree. 1916, 1919, and 1927).
