structural details clearly indicate their identity. No true affinity 

 exists with Trithemis, in which genus the species had been located by 

 some of the earlier authors.

One of the most conspicuous, common and characteristic dragon- 

 flies of the Mediterranean zone in Europe and Africa, this species is 

 evidently rather common almost everywhere in Africa, except in the 

 zones of heavy tropical rains and corresponding forest vegetation. 

 It is also found in Madagascar. If a series of C. erythraea from 

 Southern France is compared with material from the faunal region 

 here discussed no appreciable differences can be found. 



BEADINOPYGA (Kirby, 1893). 



Very closely allied to Crocothemis ; two African and one East 

 Indian species.
