in M. 2Mlitulus ; pygidium closely and shallowly punctured ; meta- 

 sternum vaguely punctured, and with a fine, median, very little raised 

 longitudinal carina ; juxta-marginal stria distinct in the posterior 

 part only. 



Length 11 mm. ; width 7| mm. 



It is quite possible that in this species, of which I have seen only 

 one female example, the peculiar form of the intervals of the elytra 

 may be caused by malformation.

" Strongly convex, sub-globose, shining black ; headrugulate trans- 

 versely in front, punctulate behind, a frontal transverse carina, 

 clypeus broadly and obtusely bi-dentate ; prothorax closely, strongly 

 and equally punctate, immarginate at base, anterior part sub-retuse 

 in the male ; elytra slightly crenato-striate, intervals moderately 

 strongly punctate, punctures sub-seriate, eighth stria carinate from 

 the base to a short distance from the apex, pygidium shining, and 

 with large, scattered punctures. 



Length 10-12 mm. 



Differs from his congeners in being shining and in the elytra 

 having moderately distinct series of punctures.

" Black, moderately shining ; head and clypeus equally rugose, the 

 frontal carina not w^ell defined except in the centre and at each end, 

 which makes it appear as if it were almost tri-tuberculate ; prothorax 

 broad and convex, with the anterior declivity well rounded and not 

 at all abrupt and without any trace of excavation, anterior margin 

 semicircularly emarginate, while in M. bias and M. greeni this 

 emargination is formed by a line twice interrupted, and with obtuse 

 angles ; ante-scutellary depression very slight ; punctuation strong, 

 dense and confluent on the disk, weaker and more scattered towards 

 the sides ; elytra with the stria3 distinctly punctate and with the 

 intervals convex, very rugose and roughly punctate, pseudepipleural
