TJie Odonata or Dragonflies of South Africa. 427 



wings is known, as described in our table. From North Nigeria the 

 writer has seen a series of andromorphous females with the wing base 

 almost as brilliant golden yellow as in males ; similar females are 

 described from Choa by Forster. The first described specimens of 

 Tritltemis Kirbyi came from North- Western India and belong to a 

 form with much paler-coloured wing bases. 



TRITHEMIS STICTICA (Burmeister, 1839). 



S. Afr. Mus. : 1 <J, Matopos (E. C. Chubb); 1 $, Latombo, 

 Salisbury (3 . iii . 1912) ; 1 <J, Krauspoort, Transvaal (21 . xii . 1906); 

 1 cJ 1 9 , White Eiver, E. Transvaal (8 . xii . 1909 ; i . 1910, A. T. 

 Cooke); 1 <J, Lorenco Marques (15 . x . 1911). Brit. Mus.: 2 J, 

 Salisbury (12 . xi . 1905, Marshall). Coll. K. J. Morton: 1^, 

 Wolhuterkop, Transvaal (i, xii. 1908, Miss Fountaiue). Coll. E. B.

South African and East African, reaching northwards to Abyssinia; 

 a few specimens are also known from western localities and from 

 Madagascar. Adult males are perhaps the most graceful LibeUuline 

 dragonflies of the pi'eseut fauna ; the contrast of the very light and 

 brilliant blue thorax, the black and yellow abdomen and the large 

 yellow cloud in the hind wings is a most striking one. The description 

 of the female in our table is made from the specimen from White 

 River, which most certainly belongs to this species. 



TRITHEMIS AUREOLA (Ris, 1912). 



S. Afr. Mus. : 1 c?, Inhambane (xii . 1912, K. H. Barnard). Coll. 

 Selys : 1 , Delagoa Bay. 



This species is very imperfectly known, though certainly distinct 

 from its ally stictlca. The writer has seen but a few more speci- 

 mens, from Dakar and from Madagascar. In the paper on Schultze's 

 voyage it was given Rambur's name Jiova. But further search 

 demonstrated that this name belonged with much better right to a 

 species of Pseudomacromia ; a new name had therefore to be given to 

 this Tr it he mis. 



TRITHEMIS DISTANTI (Kirby, 1898). 



S. Afr. Mus.: 2 $, Waterval, Transvaal (16 . xi . 1899; 

 16 . xii . 1900) ; 5 J , 6 9 , M'Fougosi, Zululaud (ii, iii, iv, v, ix, x . 1911,
