the median part as at the hase, strongly declivous behind at a 

 short distance from the middle, covered with sub-aculeate, closely 

 set, yet somewhat irregular, moderately shining tubercles the larger 

 of which are disposed in two seriate dorsal rows on each side, the 

 supra-lateral row being much more distinct, although granular, the 

 sides are deeply seriato-punctate. - 



Length 16 mm. ; width 9i mm. 



Female : Also opaque black, but with very fine, appressed naves- 

 cent hairs on the elytra ; prothorax broader and a little shorter than 

 in the male ; elytra more ampliated nearer the base and not much 

 wider across the median part than at a short distance from the 

 shoulders, more convex than the male in the anterior part, and 

 looking therefore still more declivous behind, the first and second 

 seriate rows of tubercles are only feebly indicated, and the tubercles 

 in the intervals are more scattered and less well defined, but the 

 strong granules along the lateral costa are nearly as numerous as in 

 the male. 



Length 15i mm. ; width 10 mm.

The nearest ally of this species is M. spurius, the elytra of which 

 are, however, more ampliated laterally in the middle, and the costate 

 rows of tubercles are distinctly more seriate than in M. gazanus. 

 The female also closely resembles that of M. gazanus, but is likewise 

 plainly more costate.

Plate XIII., fig. 4. 



Female : Black, but with the elytra covered by a terrenous coating; 

 head and prothorax extremely finely aciculate, opaque ; prothorax 

 short, twice as broad as long, rounded laterally, slightly wider at the 

 base than at the apex ; elytra strongly ampliated from the humeral 

 angle which is somewhat wider than the base of the prothorax, very 

 convex, and with a conspicuously rounded declivity behind, one- 

 third narrower at the base than across the median part where the 

 posterior declivity begins, and one-third less in width at their widest 

 part than long, the suture is raised and sub-tuberculate, and on each 

 side are three series of small tubercles not greatly developed in the 

 anterior part, much more so in the posterior, where they are some- 

 what aculeate, the intervals are irregularly granulose and dotted 

 with dense, long, erect grey sub-flavescent hairs, but the declivous-
