The head is sub-quadrate, black, very thickly and finely punc- 

 tured in the hinder part ; the front depressed and slightly excavated, 

 separated from the hind part by a slightly-raised semicircular 

 ridge between the eyes, terminating on each side in the porrected 

 anterior angles of the head, immediately beneath which the an- 

 tennae are affixed. The eyes are large, round and entire. The 

 antennse are slender, 1 0-jointed ; 1st joint long, covered with a few 

 erect bristles in front, the 7th joint is sub-triangular, with several 

 bristles starting from its apex ; the three joints of the capitulum 

 are of moderate length, chesnut-coloured, and clothed with fine 

 pale pubescent hairs. The mandibles are not longer than half the 

 length of the head, somewhat triangular, excavated above ; the 

 outer margin near the base elevated into an obtuse lobe, and the 

 upper edge near the tip armed with an erect triangular tooth ; they 

 are black and glossy, with a few punctures and luteous bristles. 

 The lobes of the maxillae are not armed with a curved spine on 

 the inner margin, the palpi are slender. The lower lip was un- 

 fortunately lost in the examination of the unique specimen. 



The prothorax has the sides more strongly rounded than in 

 M. irroratus, vpith all the angles acute, the margin slightly serrated, 

 the disc irregularly punctured, having several smooth patches, 

 especially down the middle and on each side behind ; the disc on 

 each side within the anterior angles is rather concave. 



The elytra are convex, and closely punctured, each puncture 

 emitting a luteous scale, the scales disposed in several longitudinal 

 series connected together by several transverse irregular patches 

 of scales; the intervening spaces less strongly punctured. The 

 legs are slender ; the anterior tibiae with about fourteen minute 

 ol)tuse serratures between the base and the tooth beyond the 

 middle, and with about seven serratures between it and the apical 

 external tooth. The middle and hind-tibiae are armed with several 

 very minute teeth, as well as with one more conspicuous in the 

 middle of the outer margin. The body beneath is pitchy-black,
