half of wing with three angular corial markings extending half across wing, 
and a small triangular spot at midlength of inner apical cell, ivory; face pale 
except for a few dark arcs in dorsal portion of muscle impressions of clypeus, 
and for all of antennal ledge except a pale horizontal stripe above base of an-

male abdominal sternum VII is very similar to the illustration of M. sociata 
(Fowler) (fig. 340p).
