Greatest dorsal width of pronotum, .... 3.2 " 5 " 



Length of tegmen, 2.6 " 4.1 "

Aparatypic series of fourteen individuals, four males and ten females, 

 have been examined in addition to the types. They are quite uniform 

 in character aside from a little variation in the intensity of the colora- 

 tion, and may be readily separated from M. hebardi by the shape and 

 length of the femora, as well as numerous other characters.
