[Plate II.] DuRIs(~ Mr. Austen's visit to Sierra Leone, as a member of :Major Ross's expedition to inquire into the connexion between Downloaded by [University of Cambridge] at 10:54 11 January 2015 mosquitos and malaria, he collected a considerable number of dragonflies; but as he captured long series whenever he was abl% the number of distinct species obtained amounted only to eighteen. However, I am able to describe seven newspecies in the present pape U two of which I have made the types of new genera. I should also mention that specimens of most of these have been in the Museum fbr some tim% bug have not previously been described. In place of quoting full synonymy in the present, pape 5 I generally confine myself to quoting references to the original 5* 68 Mr. W. F.

The only other Neuroptera in the collection were four specimens of M!/rmeleon tristis~ Walker~ taken on Sept. 5~ 1899~ and one or two small species of Ephemerid~e and Termitidse not at present determinable.

Trithemis Kalula, sp. n. (PI. II. figs. 2, 2 a.) Long. corp. 32-34 millim. ; exp. al. 53-55 millim. ; long. pter. 2 miltim. Male.FRufo-testaeeous, with hyaline wings. Very similar to T. arteriosa, Burro., from which it differs as follows:-- The segments of the abdomen are distinctly shorter and broader, and instead of a row of lateral black spots succeeded by a continuous band, there is a row of lateral black spots enlarging and expanding behind~ which are more or less expanded on the last three segments, sometimes so much as to cover most of these segments~ except a reddish spot on each side in front. The middle appendages of the same segment consist of a pair of long slender reeurved hooks. The neara- tion is brown, reddish only sometimes in the costal and post- costal areas. The yellow shade at the base of the hind wings is darker than in T. arterlosa and the cells in it are usually centred with pale brown. In adult specimens the vertex is violet~ and the thorax and abdomen are slightly pruinose, but more of a reddish plum-colour than blue. An immature male (and pre- sumably the female) has a broad brown median band on the thorax, and a narrower one on each side, the latter connected below with a longitudinal black band on the pleura, which emits three oblique brown bands downward, the hindormost connected with a black space, filled up with two pale spots in fi'ont and a large transverse one behind on the metapectus. At the base of the abdomen there are also three brown stripes above the level of the lateral markings already described. In Downloaded by [University of Cambridge] at 10:54 11 January 2015 the more mature specimens these markings are more or less obscured. Legs black. Pterostigma brow% more or less centred with yellow. 4 specimens, Aug. 26, Sept. 13, 21 (1899). Trithemis serva, sp. n. (Woodcut, fig. 1.) Long. corp. 34 millim. ; exp. el. 57 millim. ; long. pter. 2½ millim.

Wings hyaline, with black nervures; fore wings with 11-13 antenodal and 7-10 postnodal cross-nervures; pterostigma dark brown, traversed by a narrow yellow line. Triangle traversed, followed by three rows of cells, increasing; sub- triangular space consisting of 3 cells : hind wings with 7-8 Fig. 1. I !
