the juxta-humeral band, which is apparently not reduced as in M. 

 torquatus to a mere superior spot. The yellow rings on segments 4-7 

 of the abdomen are smaller, and the branches of each of the upper 

 anal appendages of the male are nearly parallel to one another. 



The venation differs but slightly from that of M. chelifer, 

 the chief distinction being apparently that the present species has its 

 venation a very little denser than in M. chelifer.

An Epigomphine genus, without a basal antenodal nervure of 

 2nd series. A maximum of at least three rows of cells between Cu 2 

 and the hinder margin of the fore-wing. Only one row of cells 

 between M, andM,,,' at level of distal end of pterostigma. Proximal 

 angle of triangle of fore-wing not so far distant from the arculus as 

 length of proximal side of sub-triangle. Forking of M,_ 3 and M + 

 unsymmetrical in both fore and hinder-wings. Two (sometimes 

 three) cross-nerves in the submedian space of all four wings. 

 Triangle of hinder-wing of female frequently crossed by a nerve 

 running parallel to long axis of wing. Pterostigma braced. Anal
