Thorax closely and rather finely punctured ; scutellum flat, rather broadly truncate 

 at the apex. Median segment as long as the scutellum, coarsely punctured-rugose, 

 abruptly truncate, the posterior slope distinctly divided from the dorsal area. 

 Abdomen finely and closely punctured, with a very narrow apical band of white 

 pubescence on the three basal dorsal segments ; the first segment short, and depressed 

 somewhat below the second, which is strongly convex, broader than long, and convex 

 at the sides ; seventh dorsal segment subtruncate at the apex. Second ventral 

 segment rather more strongly punctured than the dorsal, sparsely clothed with long 

 white hairs and with a distinct apical fringe of the same. Radial cell not more than 

 twice as long as broad ; first abscissa of the radius a little longer than the third,

This seems to belong to the group of M. thyone. Per., but differs in sculpture, in
