Elongate, a little flattened above, almost devoid of hair 

 above and beneath, the tibiae with very short and inconspic- 

 uous hair-fringes. The club of the antenna consists of three 

 not very long lamellae preceded by three very short ones. The 

 head is closely and rugosely punctured and finely setose, the 

 frontal area short and broad, the frontal ridges bisinuate, 

 meeting in an acute angle, the marginal processes very sharji- 

 pointecl. The pronotii^n is short and convex, without median 

 groove or with only a slight vestige, but with numerous close 

 deep punctures at the sides, in and near the deep lateral scars 

 and near the front angles. The dorsal striae of the elytra bear 

 very distinct fine close punctures and the sides bear narrow 

 costae comiected by close transverse bars. The prosternum is 

 opaque behind the front coxae. The mesosternum has a finely 

 rugose patch in the middle and the deep lateral scars are 

 opaque. The metasternum has a narrow, finely rugose lateral 

 depression, the anterior angles of the median area are very 

 closely and finely punctured and the hind angles coarsely and 

 confluent ly punctured. 



Length, 21 to 32 mm. ; breadth, 10 to 11 mm.

This differs from the t^-jjical phase only in having the lateral 

 scars of the mesosternum more or less punctured. The 

 author mentions an intermediate specimen from Assam and 

 anticipates that the transition will be found to be complete.

According to Gravely, this " differs from M. rotnndifrons 

 only in its smaller size, and in the extremely coarse puncturmg 

 of all the grooves of the el^lra, the dorsal grooves of M. crenu-
