TAXONOMIC NOTES AND DISTRIBUTION. The phallosome of the
Angolan quinquefasciatus is quite typical, as judging from the de-
scriptions and figures of Edwards (70), Belkin (71), Dobrotworsky (72)
and others. The inner divisions appear shorter and obviously slender
than in pipiens s. str., with blunt tips, never sharply truncate, and
usually noticeably convergent or, at most, subparallel. The sickle-shaped
parts of the outer divisions are large, moderately sclerotized, concave
plates diverging from each other for most of their lengths. Their
points largely surpass the inner divisions, so that the DV/D ratio is
always largely positive, ranging from about 1.0 to 1.5 in the appar-
ently undistorted mounts measured by the writers (Barr's method).
In all our females associated with quinque/asciatus males, the ratio
of the length of the anterior fork-cell to that of its stem ranged from
2.10 to 3.60 (mean 2.96). As it was stated under pipiens s. str., this
