The material studied was mainly collected during Dr. P. WAGENAAR HUMMELINCK’S voyages to the West Indies in the years 1930, 1936/37, 1948/49, 1955 and 1963/64, and on a special entomological collecting trip by Ir. R. H. COBBEN in 1956/57. Unless otherwise stated, a date in the years 1956 and 1957 indicates specimens collected by Ir. COBBEN, and a date in another year indicates specimens collected by Dr. WAGENAAR HUMMELINCK. Contrary to the first five papers on “Heteroptera of the Netherlands Antilles” (Stud, fauna Cur. n, 1960), THIS CONTRIBUTION ALSO DEALS WITH SPECIMENS COLLECTED ON OTHER CARIBBEAN ISLANDS.
