(3) M. ralif/inea sp. nov. 



Dark brown; the coxae of hind legs yellowish, tegmina and wings 

 brown with dark veins. Male pygophor very large; ventral edge 

 sinuate and slightly emarginate, lateral edges curved and turned 

 slightly inward, medio-ventrally there projects a plate which in ventral

 wide at base and curving off to thin apex; styles a little longer than 

 median process, slightly swollen in middle, bifurcate at apex, the ends 

 of the bifurcations rounded; anal segment very large, projecting well 

 beyond styles, in dorsal view flat, subovate, the anus at apex, the edges 

 turned down and apically meet beneath anus, thus forming a large 

 concavity on the ventral side of segment, in which lies the large 

 and complex penis.
