perfectly smoot/i or mimttcly priclded. Above dark greyish olive etc- , some- 



times a distinct dark temporal spöt. 



The species seems to be limited to East Af rica, being recorded from Zanzibar, 

 German and British East Africa north to Eritrea.

1 specimen, Nairobi, in a small waterpool on a grassy plain in the Forest re- 

 serve at the Limnrn-road. 7* 1911. 19 mm. in length. 



When the animal was alive, »the white dorsal stripe» mentioned in the descrip- 

 tion, was reddish, bnt is now, only two months after the specimen was captured, 

 nearly perfectly discoloured. It is broader and more distinct than in BoulEnger's 

 figure. On the lower part of the hind side of the tibia we find also a stripe like 

 that on the back, which stripe also is to be seen in the two specimens which Sjö- 

 stedt brought home from Kibonoto, German East Africa. 



As far as I can see, the species is hitherto mentioned from Somaliland, German 

 East Africa, Portugise Guinea, Uganda and Soudan, thus having a rather wide geo- 

 graphical range. 



Rappia symetrica Mocquard. — Plate 2, Fig. 2. 



Mocquakd, Boll. mus. d'Hist. nat. Paris, Tom 8, 1902. p. 408. 



28 specimens caught along the road between Blue-Post (Thika river) and Roiru 

 river on the steppe where the grass had recently been burnt off; 3 — 4 april 1911. 



Some of the specimens correspond very well with Mocquard's exact description 

 of Rappia symetrica, which description is based, however, only upon a single specimen 

 which also has been caught in British East Africa at Athi river among the Kikuyu- 

 hills. Several of them differ, however, considerably with regard to the colour, and 

 — I ara sure — these should not have been identified with this species, if they had 

 not been collected together with the other specimens which in my opinion certainly 

 belong to the species Rappia symetrica, and with which they are distinctly connected 

 by a great number of very beautiful intermediate forms, which fully prove that all 

 the specimens of this collection belong to the same species. 



In correspondence with Tornier's account of the variations of the genus Rappia 

 (Deutsch-Ost- Afrika, Lief. 4, Berlin 1896) I give in the figure 2 a — ea series of drawings 

 of different specimens arranged in the same way as Tornier has done, beginning 

 with the darkest (youngest) specimens and ending with the uniform light-coloured 

 ones which have assumed the appearence of the adult. Such series of colour varia- 

 tions occurring in a species are probably the only way of getting a correct estimation 

 of such a variable genus as Rappia.
