138 LUCANIDiE. 



narrow but with the prothorax broad. The sides of the latter 

 gently and evenly rounded, without lateral angulation, the 

 base very broad and the hind angle rounded. The scutellum 

 evenly punctured. The sides of the elytra nearly straight 

 and parallel and the shoulders acute. The jirosternal process 

 short and rather bluntly pointed. The entire outer edge of 

 the front tibia is finely serrate, with larger l)ut rather minute 

 sharp teeth, rather widely spaced, and tlu^ middle and hind 

 tibiae have each a well-marked lateral spine near the middle. 

 The club of the antenna moderately long and the seventh joint 

 sharply produced. 



(J. The upper surface is entirely opaque, the head rather 

 closely and evenl}^ but not strongly or densely punctured, the 

 pronotum with the punctures fine and not very close in the 

 middle and becoming strong and dense at the sides. The head 

 is flat and moderately broad, with very blunt front angles and 

 without trace of prominence behind the eyes. The clyt^eal 

 process is short and rather broad, with the front margin 

 straight and the angles blunt. The mandibles are very short, 

 strongly and evenly curved, very sharjjly pointed, with a short 

 truncate or two-cusped horizontal tooth above, near the middle 

 of the inner edge, united by a curved line to the basal part and 

 forming an acute angle with the apical part. The jnonotum 

 is much broader behind than in front and the front angles are 

 produced but not very sharji. The elytra are finely and very 

 densely punctured, a little less densely near the base, with a 

 narrow smooth sub-nitid sutural strip marked off by an 

 irregularly j)unctured stria. The mentum is very densely 

 clothed with erect yellow hairs.

Type in the British Museum. 



Closely resembling M. humilis, it is distinguished at first 

 sight by its entirely opaque upper surface. The prothorax 

 is relatively wider and the elytra are narrower than those of 

 M. humilis. The tarsal fringes are shorter than in that species, 

 the front tibiae are rather more strongly tootlu^d and the four 

 posterior tibiae have larger spines. The prosternal process 

 is shorter and blunter.
