Description: A survey is given of the assassin bugs (Reduviidae) collected on the six Netherlands Antilles. All together 22 species were sampled: 6 Emesinae, 1 Saicinae, 8 Harpactorinae, 1 Piratinae, 4 Stenopodinae, 1 Triatominae and 1 Phymatinae. Sixteen species were captured on the three islands of the Leeward Group, Aruba, Curaçao and Bonaire; seven species were found on the three islands of the Windward Group, St. Eustatius, Saba and St. Martin; both groups of islands have only 1 species in common. The local distribution of the species represented (Table 1) does not fit with their known gross distribution in the neotropics. Curaçao harbours more than 70% of the total number of species; zoogeographical aspects have been discussed. Two species are described as new; Cosmoclopius curacavensis (Harpactorinae), living on Curaçao as a predator exclusively on the weed Cleome viscosa, and Oncerotrachelus sabensis (Saicinae) from Saba. The identity of some Emesinae and the single phimatine specimen captured remain unsettled for the present. Triatoma maculata. vector of a T. cruzi strain with low virulence, occurs in two colour forms; the dark one restricted to Aruba, the light-coloured form to Curaçao and Bonaire. Total drawings of most species are presented in addition to some 120 figures of structural details of eggs, larvae and adults. Features of eggs and genitalia are discussed on pages 17-28. Some points of general interest are: The egg of Sinea coronata appeared to be quite different from what is known from other Sinea spp. Eggs of Piratinae have movable slips with plastron function. The harpactorines Atrachelus fuscus and Sinea coronata lack parameres. Behavioural aspects concerned with utilizing sticky material have been summarized. Evidence is presented that the subrectal gland, occurring in many Harpactorinae, secretes the colleterial liquid for the egg-batch. The asymmetrical genitalia of the Piratinae and the endosomal brush zone and basal differentiation of the ductus ejaculatorius in some Stenopodinae are stressed.

Description: The material of Saldidae covered in this paper comprises: Pentacora signoreti, from St. Martin; Pentacora sphacelata, from Aruba, Curaçao, Klein Curaçao, Bonaire, and St. Martin; Saldula “palustris”, from St. Martin; Saldula dentulata, from Curaçao, and Bonaire; Micracanthia humilis, from Curaçao, St. Eustatius, and St. Martin; Micracanthia drakei, n. sp., from Aruba, Curaçao, and Bonaire; Micracanthia husseyi, from St. Martin.

Description: The present paper is based upon a small collection of water striders of the family Hebridae, collected by the junior author while conducting a field survey of the Hemiptera of Curaçao and the other Netherlands Antillean islands in the Caribbean Sea. It is striking that the hebrids mentioned here were found only on the three islands of the Leeward Group, off the coast of Venezuela, i.e. Aruba, Curaçao and Bonaire. On the very small islands of St. Martin, St. Eustatius and Saba, situated about 900 km farther to the northeast, not a single hebrid has been met with, in spite of the fact that suitable habitats were examined very carefully for their occurrence. The collection comprises four species of hebrids, divided between two genera: Merragata hebroides, from Aruba, Curaçao, and Bonaire; Hebrus concinnus, from Curaçao; Hebrus consolidus, from Curaçao; Hebrus elimatus, nov., from Aruba, Curaçao, and Bonaire.

Description: The present paper is based upon the lace bugs, Family Tingidae, collected by the junior author in the West Indies, on the islands of Aruba, Curaçao, Bonaire, St. Martin, Saba, and St. Eustatius. This collection of several tingids comprises 17 species, including the five new forms described below. The larval stages of most of these species will be dealt with by the junior author in a separate contribution to the present series. Dictyla parmata, from Aruba, Curaçao, and Bonaire; Dictyla alia, n. sp., from Aruba, Curaçao, and Bonaire; Teleonemia validicornis, from Curaçao; Teleonemia scrupulosa, from Aruba, Curaçao, Klein Bonaire, and Bonaire; Teleonemia syssita, n. sp., from St. Eustatius, Saba, and St. Martin; Teleonemia sacchari, from St. Eustatius, Saba, and St. Martin; Acanthocheila thaumana, n. sp., from St. Eustatius, and St. Martin; Leptopharsa ruris, from St. Martin; Vatiga illudens, from St. Eustatius; Phymacysta tumida, from Aruba, Bonaire, and St. Eustatius; Gargaphia nigrinervis, from Aruba, Curaçao, and Bonaire; Corythaica carinata, from Aruba, Curaçao, St. Eustatius, Saba, and St. Martin; Corythaica cyathicollis, from Aruba, Curaçao, St. Eustatius, Saba, and St. Martin; Corythucha gossypii, from Aruba, Curaçao, Bonaire, St. Eustatius, Saba, and St. Martin; Corythucha morrilli, from Aruba, Curaçao, Bonaire, and St. Eustatius; Corythucha championi, n. sp., from Curaçao; Corythucha agalma, n. sp., from Saba.

Description: The data concerning the heteropterous fauna of the Netherlands Antilles from which the following series of contributions has been compiled are chiefly the result of an entomological study trip lasting from September 1956 until July 1957. The investigations were carried out under the auspices of, and sponsored by, the Natuurwetenschappelijke Studiekring voor Suriname en de Nederlandse Antillen (Foundation for Scientific Research in Surinam and the Netherlands Antilles), with financial assistance from the Government of the Netherlands Antilles. I wish to express my appreciation to the Foundation for making it possible for me to undertake this mission.

Description: This paper is a further contribution to the knowledge of the Heteroptera of the Netherlands Antilles continuing the series on bugs of this region (COBBEN, 1960a, b; DRAKE & COBBEN, 1960a, b; WYGODZINSKY, 1960; NIESER, 1967, 1969a, b; COBBEN & WYGODZINSKY, 1975). It is based on the material of berytinids collected by the second author while studying the bugs of these islands. The material collected contained a total number of 65 specimens of Berytinidae divided into 3 genera and 3 species: Pronotacantha armata Stusak, from Curaçao; Aknisus multispinus Ashmead, from Bonaire, Aruba and Curaçao; Jalysus reductus Barber, from Saba, St. Eustatius and Curaçao. Pronotacantha armata and Aknisus multispinus had not yet been recorded from the Antilles. Jalysus reductus is already known from the region studied; however, it is recorded here for the first time from the Lesser Antilles.

Description: In the keys to the palaearctic Saldidae, which will be published before long in Dr. W. Stichels: "Illustrierte Bestimmungstabellen der Wanzen Europas", I shall use systematic conceptions, deviating from those which were up till now generally used. The character of the work mentioned does not permit a motivation. The following notes serve as an introduction to the system, as proposed in Stichel.\n\nCONTENTS\nI. Major classification. A. Relation to other families B. Subfamilies C. Tribes II. The problem of generic divisions.\nIII. On the status of some palaearctic forms.\nIV. Saldula heijningeni spec. nov.\nI.\nMAJOR CLASSIFICATION\nA. Relation to other families A study of the egg development (position of germband, blastokinesis and eclosion) of Saldidae and other families (not published) has shown that the hypothesis of China (1950) that the saldids should belong to the Amphibicorisae, is justified. Of old they have been treated as representatives of the Geocorisae.\nB. Subfamilies Up till now the division in Saldinae Van Duzee 1917 and Saldoidinae Reuter 1912 has always been in use. To the latter belongs only the genus Saldoida Osborn 1901, while under the former all remaining (momently 15) genera are grouped. The three species of Saldoida have always attracted
