Resembles M. cylindricus Jord. (1904), from Tonkin, but the antenna is 

 somewhat thicker, and segments 7 and 8 are entirely pubescent-white, while in 

 M. cylindricus the tip of the seventh, the entire eighth, and the base of the ninth 

 are white. The sides of the pronotum are black, with a grey dot before the middle 

 and another some distance in front of the carina. The grey markings of the elytra 

 .are edged with russet ; the declivous apex is grey, with some russet and black

spots. The groove on the presternum runs parallel with the margins of the coxal 

 cavities, entering in between the coxa, and therefore resembling the figure 3. In 

 M. cylindricus this groove is almost straight in front and much deeper (cf. text-figs. 3, 

 vitalis; 4, cylindricus). The mesosternal process is rather narrower apically than 

 in M. cylindricus, and the second basal segment is quite black. 



Differs from M. vitticollis especially in segment 6 of the antenna being black, 

 in the pronotum being somewhat depressed longitudinally on each side of the 

 middle, the centre appearing somewhat raised and bearing a black spot in the grey 

 median vitta.
