Allied to M. Goilcfredi, Eados. and Sich., but easily distinguished 

 by the yellow pubescence clothing the vertex of the head and the 

 prothorax, the presence of three ventral caringe on the second seg-

 on the dorsal part of the thorax, the non-interrupted white band on 

 the third abdominal segment, and also the more carinate process of 

 the scutellum.

Shape, size, and colour of M. cloantlia, but the mesothorax is not 

 clothed with greyish or sub-flavescent hairs, and the post-scutellary 

 region and the base of the rnetathorax are clothed with a dense, silky 

 subflavescent pubescence ; the metathorax has a broad, median groove,
