Oviduct much curved, not more than one-fourth of the length of the abdo-

 femora and four anterior with two rows of minute spines; hind tibi* with 

 four rows, which are mostly on the two upper keels. Fore wings shorter by 

 two lines than the hind wings, broadest at somewhat before half the length ; 

 reticulation extremely minute; costa pale yellow. Hind wings as usual.

It may be distinguished from M. Toltecum by the protborax, which is 

 much longer than its breadth near the hind border and is not elevated on 

 the sides of the disk. It differs from M. Coulonianum by the fore wings, 

 whose greatest breadth is before the middle, and by the hind femora, which 

 are not more than half the length of the fore wings.
