The singularity of the markings on the elytra will at 

 once separate the beautiful insect from any hitherto 

 described species. The marginal bands radiate from 

 within outwards, and would (if produced inwardly) meet 

 nearly in the centre of the suture ; they are frequently 

 dilated, leaving only six narrow fulvous lines. 



MesompJial'ia emorsitans. 



Anguste ovata, postice valde attenuata, convexa, 

 obscure nigro-senea, subnitida, pube adpressa sericea 

 sparse vestita; subtus magis nitida, antennis nigris; 

 thorace longitudine duplo latiori, lateribus ante medium 

 oblique ampliatis, deinde rotundatis, hinc ad basin rectis, 

 parallelis ; disco foveolato, impunctato, sparsissime cinereo 

 sericeo ; elytris thorace multo latioribus, humeris antror- 

 sum leviter prominulis, apice rotundatis, lateribus pone 

 humeros fere ad medium ampliato-rotundatis, hinc ad 

 apicem rotundato-angustatis, apice conjunctim subacutis ; 

 supra (praesertim ante medium) convexis, basi obsolete 

 retusis, crebre et fortiter punctatis, disco ante medium 

 reticulato-rugosis ; margine laterali modice ampliato, 

 vitta submarginali, postice angustata, intus bis-emar- 

 ginata, vix infra basin ad apicem extensa, pallide fulva, 

 ornato.

Very similar in form and sculpture both of thorax and 

 elytra to M. hlandifica, Boh., the elytra rather more 

 convex, less produced at the apex, and the shoulders 

 rather less distinct ; although so differently coloured, it 

 is not unlikely to prove a variety of that species.
