(Text-fig. 64). Ou first ventral plate a flat transverse tuliercle covered 

 with minute spinules. 



Wings rather rich golden yellow in basal and costal half to distal 

 end of pterostignia. Pterostigma light ochreous. 



Menibranule white in proximal, blackish in distal half. Costa light 

 yellow ; cross-veins to nodus, triangle and Cu light yellow. Venation 

 as in A. subjmjnUata in all essential points.

 but in a note another female with " wings much tinged with yellowish "' 

 is mentioned as " possibly a distinct species." The (later) description

of A. dolabrata by Karsch agrees also with our specimens so well that 

 I strongly suspect this species to be the same as MacLachlan's. 



ANACIAESCHNA (St'lys, 1878), 

 The genus was originally founded for a single widely distributed 

 and common species, A. jaspidea, Burm., which ranges from India to 

 Polynesia, but has not yet been oliserved in Africa. From this 

 continent a second species was described by MacLachlau from Delagoa 

 Bay ; it is evidently less common than jaspidea seems to be in its 

 haunts. Our description is taken from an Abyssinian specimen, which 

 agrees with the original description in all essential points. The 

 definition and name of the genus were originally taken from the 

 presence of accessory lateral carinae in the abdomen of A. jaspidea. 

 But I find these carinae often indistinct in the female oi jaspidea, and
