rounded, most often a single row of cells Bs-lisjil. Though analogous 

 to bmchiale in elements of pattern, this species is darker in every 

 respect, and the darkest of the pruinose blue African species of 

 Orthetrum. Black colour in female and uou-pruinose male almost 

 equally light-coloured area, or surpassing it in many males ; ptero- 

 stigma regularly very dark brown or blackish in mature specimens ; 

 ante-nodal cross-veins in sub-costal space black even in very immature 

 examples ; basal spot in hind wings mostly darker iu mature specimens 

 than in other species (some isolated specimens of guineense excepted), 

 deep golden brown to almost blackish and not rarely jiruinose in 

 very mature males ; golden yellow in females ; not rarely females 

 with yellowish colour of base diffusely extended to level of triangles 

 and even more distally. Hamuli nearest O. guineense, but internal 

 branch more slender and excision between the two branches not so 

 deep. 



A very common species in equatorial Africa, West and East
