brevibus nigris (nisi sub lente vix perspicuis) sparsim vestitus ; 

 capite pedibusque certo adspectu totis albis ; prothoracis spinis 

 lateralibus et disco antice, utrinque albis ; antennis fuscis, 

 articulis singulis basi albis ; prothorace (spinis lateralibus ex- 

 clusis) quam longiori parum latiori, antice quam post ice paullo 

 angustiori, supra parum depresso, utrinque spina brevi conica 

 instructo, supra fortiter subcrebre (ad latera crassissime) punctu- 

 lato, lateribus leviter arcuatis; scutello baud transverso, apice 

 subacuminato : elytris prothorace (spinis lateralibus inclusis) vix 

 latioribus carinis 2 serratis instructis, carina discoidali antice 

 procossum magnum obtusum suberectum formanti ; parte dimidia 

 discoidali antica subtiliter sat crebre (postica vix perspicue) 

 punctulata ; partibus tertiis anticis 2 declivibus lateralibus, sat 

 crebre granulatis; apice singulatim suboblique truncato vix 

 explanato. [I^oi^g- l^j l^t 3 J lines (vix). 



Differs from M. WaterJwusei, Pasc, inter alia hy the longitudinal 

 line on the head running very conspicuously the whole length from 

 the clypeus to far behind the level of the eyes, by the length of the 

 scutellum equal to the width of the same, by the truncate apices 

 of the elytra, by the shape of the elytral carin89 — which are 

 continuous, though their outline (from any point of view) appears 

 serrated — by the form of the process at the base of the inner 



carina, which closely resembles the pommel of a lady's saddle — 



being compressed, with a roundly truncate apex. 



Differs from M. Mormon, Pasc, and from M. assimilis in many 



respects, and especially in the totally different scutellum. 



When closely examined this species appears to be rather closely 



sprinkled all over with minute snowy- white spots, such spots 



consisting of single white scales interspersed with the darker 



ones.
