Female. Length 4 lines.—Ferruginous, the eyes, flagellum, 
and tips of the mandibles fuseo-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 tibie slightly fuscous. Abdomen oyate, the

This species in colouring corresponds with the M. ferrugata 
of Fabricius, but the thorax is of quite a different form to that 
of the insect which is considered to represent that species; in 
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. ;
