Female. Length 4 lines. — Ferruginous, the eyes, flagellum, 

 and tips of the mandibles fusco-testaceous. Thorax, as well as 

 the head, closely and strongly punctured ; the sides of the former 

 parallel, or in some specimens slightly widest posteriorly, tips of 

 the femora and tibiae slightly fuscous. Abdomen ovate, the

This species in colouring corresponds with the M. ferrugata 

 of Fabricius, but the thorax is of quite a different form to that

 the present species the thorax is more elongate and the sides 

 nearly parallel ; in the other it is shorter, and gradually narrows 

 towards the abdomen.
