Scanning electron micrographs are used to provide descriptions of the eggs of Aedes (Finlaya) alboannulatus and Ae. (Fin.) rubrithorax. The structure in both eggs is complex and basically similar, with the outer chorionic cells differing completely between the ventral (upper) and dorsal (lower) surfaces. Among eggs of Finlaya species so far described, these two are unusual in having, in the mid-ventral line (upper surface), a strip of outer chorionic cells which differs substantially from those on the remainder of the ventral and lateral surfaces. Cells in this strip are wider in the anterior/posterior direction than circumferentially, and contain several medium-sized tubercles. Cells in the immediately adjacent ventrolateral and more lateral regions are proportionately wider circumferentially and contain a single large, central tubercle with several small, peripheral ones. The dorsal (lower) surface in each case is composed of cells covered with many small tubercles, which are elongated into filaments that together form a dense mat. In the subgenus Finlaya, such filaments are known only from Ae. togoi but are present also in two Haemagogus species recently described.
