J. RACENIS listed and described new species of Caloplerygidae (1968, Mem. Soc. Cien. nal. La. Salle 80: 151-176), Gomphidae, Aeshnidae and Corduliidae (1970, Ada biol. venez. 7; 23-39) for the region, but nothing has been written concerning the other families. Canaima is described t>y him (1968, cf. above) as "a locality situated near the junction of the Rio Carrao and Rio Caroni, located northeast of Auyantepui composed of open savannahs, marshes and forest zones at the margins of rivers. The altitude is approximately 700 m above sea level". Canaima is best known as the stepping-off point for excursions to the magnificent Angel Falls. The site is composed of small bungalows for guests and is next to a small Indian village. During 22-25 September. 1980. my wife, Jo, and I collected at the following areas in Canaima: (I) Beside the cabanas in the main village. — (2) At small, sandy stream leading into the Rio Carrao. The vegetation is dense and affords little insolation. — (3) Small open stream about I m deep between airstrip and cabanas. This area is generally free of dense vegetation, and the water is lentic in one area. This permits a different assemblage of Odonata from that found in the marshes. The stream drains an open marsh habitat dotted by palms. — f4t Marsh/savannah land, a low-lying marsh and grassy habitat characteristic of most of the area north of the airstrip. — (5) Forest trails above the cabanas and near Rio Carrao cataracts.
