1. Lestes tridens (MacLachl., 1895), Z. c.,p. 308, uo. 6.— The descrip- 

 tion, made from one male from Delagoa Bay, does not apply to any 

 species known to the writer. 



2. Lesles obscurus (Kirby, 1898, 1905), I.e.. p. 308. no. 7.— Mr. 

 Herbert Campion writes to me (9. xii . 1913) that the specimens so 

 described by Kirby are identical with L. plagiains. 



3. Metacnemis angusta (Selys, 1863, 1886), /. r., p. 310, no. 15.— 

 Described from a single female, " Cap de Bonne Esperauce, de 

 I'ancieune collection Latreille." 



4. Argia concinna (Eamb., 1842), I.e., p. 310, uo. 17. — This species 

 is known from the original pair alone, said to be from " Cap "" (de 

 Bonne Esperauce). I have seen the pair; it is similar in facies to its 

 American congeners of the ty^efissa, oculata, etc. But the configura- 

 tion of the apical border of the tenth segment of ij is peculiar, as 



Appendages, right side and dorsal 



described and remarked upon by St'lys (1866) and shown by Hageu's 

 figures (published by Calvert, 1902). None of the numerous species 

 of Argia known to the writer is similar to concinna in this structure. 

 The possibility, though perhaps not the probability, remains open that 

 this species, though belonging to an otherwise strictly American genus, 

 is really African. 



5. Enallagma obliterafum (Selys, 1876), /. c, p. 314, uo. 21. — This is 

 almost certainly a colour variety of E. glaucvm (see p. 326, ante). 



6. Pseiidagrion Kersieni (Gerstiicker, 1869), I. c, p. 315, no. 26. — 

 The specimens (1 $,1 incomplete S) from South Africa under this 

 name (I. c, p. 316) are very probably P. natalense of the present paper 

 {ante, p. 307). 



7. Pseudagrion Deckeni (Gerstiicker, 1869), I.e.. p. 316, uo. 27. — 

 Karsch has decided (1893) for the identity of Selys" P. praete.riatum
