This beautiful species in form closely resembles the rest of its con- 

 geners ; in pattern of colour (rufo-flavous and black) it bears a 

 striking resemblance to PTiysimerus ephippium. The head is very ob- 

 soletely impressed between the eyes with a medial longitudinal 

 fovea ; the surface is impunctate. The thorax is transverse, almost 

 quadrate ; the sides are broadly marginate, and in outline somewhat 

 sinuate; at the base is a transverse thread-like fovea, which is 

 terminated by being inflected into the line of the base before it 

 reaches the lateral margins ; the surface is impunctate and glabrous ; 

 the colour is flavous, with an irregular suffused medial marking of 

 fuscous. Scutellum large, triangular, impunctate, rufo-flavous. 

 Elytra broad, robust, depressed, punctate-striate (less distinctly near 

 the apex) ; the anterior part of the surface is black, the posterior 

 rufo-flavous, the line of division being transverse in direction, and 

 postmedial ; a large flavous maculation, irregular in outline, occupies 

 nearly the whole of the anterior and black portion of the surface 

 (being separated from the suture and also from the margination by 

 the breadth of a single stria) ; the surface also near the scutellum is 

 suffused with rufous. Antennce flavo-rufous. Legs flavo-rufous, 

 faintly suffused with fuscous. 



M. ephippium is a very distinct and beautiful species : it differs 

 entirely from all other species that I have seen ; the black antemedial 

 portion of the elytra, which contains within it, on either elytron, a 

 large irregular maculation of fulvous, abundantly separates it.
