One of the females bears the collector's note: "Settles only on 

 granite boulders at a distance from water; very difficult to detect, 

 also very local." This observation is of special interest with regard to 

 the most peculiar chequered pattern of this species, a pattern which 

 might be justly claimed as granite colour. This and the preceding- 

 species are somehow intermediate between Crocf>th<*mis and Bradino- 

 pi/ga in neural [characters and in general facies, though probably the 

 Crocothemis characters may be claimed as prevalent.

Although found north to Nigeria, Sierra Leone and Abyssinia, this 

 species is more decidedly South African than C. erythraea. No true 

 intermediates between the two species are known to the writer ; speci- 

 mens of saiigulnolenta lacking the blackish markings of abdomen are 

 found in intertropical Africa and Abyssinia, but their forms and
