Brechmorhoga, gen. nov. 



Male. — Frontal tubercle bifid ; abdomen much longer than 

 the hind wings, moderately slender, inflated at base, and 

 gradually thickened towards the extremity. Wings mode- 

 rately long and broad ; pterostigma moderately long : fore 

 wings with 12 or 13 antenodal and 6 or 7 postnodal nervures, 

 the last antenodal and two first postnodals not continuous ; 

 triangle slightly oblique, free (or, more rarely, traversed), 

 followed by two rows of cells, increasing ; the post-triangular 

 space has a loop-nervure above, enclosing 7 or 8 cells, and is 

 half as broad again at the hind margin as at the triangle ; 

 subtriangular space consisting of three cells : hind wings 

 with 8 or 9 antenodal and 7 to 9 postnodal nervures, the two 

 first postnodals not continuous ; upper anal appendages longer 

 than the eighth segment, hairy, not much thickened laterally 

 before the extremity, which is pointed ; lower appendage 

 nearly as long as the upper : legs long ; femora slightly 

 thickened and denticulated in front, with a double row of 

 bristles. Other characters as in Macrothemis, Hagen. 



In Macrothemis the frontal tubercle is not bifid, the post- 

 triangular space on the fore wings has no loop-nervure, 

 and the two rows of cells only increase close to the hind 

 margin, where the space is scarcely, if at all, broader than at 

 the triangle.
