The small collection of tiger-beetles, belonging to the genus Cicindela, which is the subject of this paper, was made by Dr P. Wagenaar Hummelinck during his visits to the Lesser Antilles and the adjacent South American mainland coast in 1936-’37 and 1948-’49. The greater part of the material has been deposited at the „Zoölogisch Museum” of Amsterdam and the „Rijksmuseum van Natuurlijke Historie” at Leiden. Some specimens (14 C. auraria, 10 C. graphiptera and 9 C. trifasciata) were presented to the collections of the American Museum of Natural History, British Museum, Deutsches Entomologisches Institut, Hope Department of Entomology at Oxford, The Imperial College of Tropical Agriculture in Trinidad, Institut Royal des Sciences Naturelles de Belgique at Brussel, Musée National d’Histoire Naturelle at Paris, Natural History Museum of Jamaica at Kingston, United States National Museum, and the Zoological Museum (including the collection E. Suenson) at Copenhagen, whose keepers kindly entrusted me with some material included in this study. The specimens from the U.S. Nat. Mus. were presented to Amsterdam, those from the Amer. Mus. to Leiden.
