very slender, as long as the two following joints taken toge- 

 ther, rather closely and obscurely punctured; the fourth, fifth, 

 and sixth joints more distinctly and moderately thickly punc- 

 tured ; the seventh more finely punctured ; the eighth to 

 eleventh joints closely and longitudinally strigose ; the three 

 apical joints together equalling the third joint in length. 

 Head closely rugose ; the eyes large and approximate, their 

 distance above about equal to two thirds the upper part of the 

 eye ; in M. asperata % the distance is about one third 

 greater than the width of the upper part of the eye. Thorax 

 densely rugose, the margins with a few irregular crenulations, 

 the posterior angles produced into a very acute spine. Elytra 

 very long, subparallel, opaque, rather thickly punctured, the 

 punctures round and lightly impressed, the base thickly 

 studded with minute shining granules ; each elytron with three 

 fine costaa, and with a trace of a short fourth one near the 

 apex, the space between the costas flattened, or even slightly 

 concave posteriorly ; sutural angle furnished with a stout 

 acute spine, which turns slightly outwards. Femora sparingly 

 and obscurely punctured ; the tibia? slightly dull and finely 

 punctured ; tarsi rather long and slender. Fifth abdominal 

 segment truncate at the apex.

$ . Head very strongly rugose-punctate ; the distance 

 between the eyes nearly equal to the width of the upper part 

 of the eye. Antenna? not quite so long as the elytra ; the 

 basal joint not very large, rather closely and strongly punc- 

 tured 5 the third joint as long as the two following taken 

 together ; the third to sixth joints sparingly punctured ; the 

 seventh and eighth joints with a strigose spot at the apex ; 

 the apical half of the ninth and the whole of the tenth and 

 eleventh joints longitudinally channelled, opaque ; the three 

 apical joints together as long as the third and half the fourth 

 together. Thorax closely and strongly rugose-punctate, the 

 sides with two or three very short acute teeth, or without 

 any ; the posterior angle furnished with a slender very acute 

 spine. Elytra long, widest behind the middle, and then a 

 little narrowed to the apex, coriaceous, the base somewhat 

 closely (but not very strongly) rugulose ; near the scutellum 

 are some minute granules or tubercles ; the sutural angle has 

 a conical acute spine. The femora are rather sparingly punc- 

 tured, the anterior pair with a few very acute spines below; 

 the four posterior femora have a few, acute, thorn-like spines 

 above and below; the tibiae are finely longitudinally wrinkled,
