the prothorax with six spots — two, semilunate, on the ante- 

 rior portion and four, confluent, near the base ; the elytra 

 with four spots — one sub-basal, median, one submarginal, 

 posthumeral, one subsutural, a little before the middle, and 

 one aiiteapical. " It is compared with the Asiatic M. com- 

 posita, Walk., and the African M. elegaaS; Alakl. 



The unique example known measures 14) mm. in lengtli.

Robust, elongate, cuneiform, deep black, the anterior coxae, 

 the anterior femora in part, and the palpi testaceous, the an- 

 tennse often fuscous, with the base testaceous ; clothed with 

 black and wdiitish or cinereous pubescence, which is con- 

 densed into the following sharply defined markings : — The 

 head with a large ])atch on the middle of the vertex, and the 

 |)rothoi"ax with an interrupted median vitta and a large tri- 

 angular mark on each side of it, infuscate or black, for the rest 

 whitish, cinereous, or flavo-cinereous ; the elytra with three 

 strongly angulate narrrow fasciae — one sub-basal, irregularly 

 branching forwaixls (enclosing an oblique oval spot on the 

 disc, an oblique humeral streak, a common postscutellar 

 patch, and sometimes a small spot on each side of it), and 

 one a little before and another just beyond the middle, these 

 two connected along the suture — and a broader, simply 

 arcuate, transverse fascia just before the apex, whitish or 

 cinereous, for the rest black ; the ventral segments at the 

 base or laterally, the side-pieces of the metasternum, and 

 the pygidium in great part above, also Mhite. Antennae 

 slender, moderately long in $ , shorter in ? , joint 2 shorter 

 and stouter than 3, 3-11 nearly equal in length, 5-10

 broadly securiform, nearly as Avide as the inter-antennal 

 portion of the head in both sexes. Prothorax broader than 

 the head and elytra, deeply bisinuate at the base, rounded 

 at the sides. Elyti'a long, narrowing from the base, Py-
