They are best called supraorbital setae to distin- guish them from infraorbital setae located posterior to the eyes on the ventral surface of the head (15). Antennal setae (10 and 11) will be discussed later with the antenna. We will now describe the last pair of setae visible on top (12) which Monchadskii, in the second edition (1951) of his review, called the antennal root hair. In the first edition (1936) he, like many other foreign scientists, called them sub-antennal. Marshall (1938) called them the basal setae as distinguished from the subbasal setae (13), only visible ventrally. They are, in fact, close to the antennal bases, almost on the extreme anterior margin of the lateral surfaces of the genae (Fig. 28, 12). We prefer then to give them the topogra- phic name, upper anterior genal setae and the setae located below 51 them on the ventral surface of the head (13), the lower anterior genal setae. The upper anterior genal setae of Culisetina mosquitoes are similar to the frontal setae, that is, pubescent-flabellate with signifi- cant branching. Setae on the ventral surface of the head, including the mandibu- lar (16 and 19), which we will discuss while studying the maxillae, are very poorly developed in Culisetina. They are simple or two- or.
