lower snrface fairly closely covered with separated white' 

 scales throiiirliout. 



Head minutely shaareened, with an indistinct network of 

 raised lines and a strono^ lono-itudtnal carina on the vertex ; 

 tlie forehead only slightly depressed below the level of the 

 eyes and wirh a faint central carina. Rostrum moderately 

 stout, very slightly widened from the middle to the apex; the 

 basal halt' shagreened, vfith a well-marked central carina and 

 another on each side of it, the apical half sliining in the 

 middle and with several rows of very shallow punctures at 

 the sides. Antennce with the scape sharply pointed at the 

 apex ; the funicle with joint 1 about as long as 2 and twice 

 as thick, 3 a trifle longer than 2, 4 shorter than 2, and 5 and 

 6 shorter still and bead-like, 5 as long as broad, 6 transverse. 

 Prothorax very strongly and regularly convex transversely, 

 the sides about equal to half the basal margin, almost straight 

 and with a moderate apical constriction, the front margin 

 produced into a sharp obtuse angle in the middle, the basal 

 spine very long (more than one-third the length of the elytra), 

 the basal margin forming on each side an angle of about 75°^ 

 with the main axis ; the upper surface finely shagreened and 

 dull, with a strong complete central carina and a large-meshed 

 reticulation of fine raised lines, without any conspicuous 

 depressions ; the dorsal outline moderately curved, sloping 

 gradually from the base to one-third, and thence much more 

 steeply. Elytra about as long as their united width at the 

 shoulders and very broadly rounded behind, the humeral 

 slope forming an angle of about 45° with the suture ; the 

 striae broad, shining, and deeply punctate, the intervals 

 rather narrower^ carinate and minutely granulate; the dorsal 

 outline convex, deepest before the middle, sloping gradually 

 to the base and more steeply behind. Legs black, clothed 

 with separated setiform white scales, the tarsi piceous ; all 

 the femora with a sharp tooth, the dorsal a})ical fringe of the 

 hind tibia longer than the first tarsal joint, tlie claws unusually 

 small. Sternum : the space between the front coxse as broad 

 as the rostrum ; the meso- and metasternum broadly exca- 

 vated, the end of the furrow sloping gradually up to the base 

 of the metasternum, and the mesosternum being almost 

 horizontal. 



Length l?-lf, breadth 1^-1^ mm.

 {H. Mann, Puaa Coll.). AsSAM : Sylhet (type). 



Allied to M. nigrorufn^ Mots., but, apart from its red- 

 brown colouring, distinctly narrower form, and unarmed 

 femora, that species has the prothorax much more finely
