raised ; elytra depressed in the dorsal part, each with five raised lines 

 (costse), the said lines somewhat obliterated past the middle, with the 

 intervals closely fossulated, and coarsely punctuated towards the

 legs brassy-black.

 pi. Ti, fig. 6. 



Black with brassy tinge on the upper part, steel-blue underneath ; 

 head strigose, labrum black with outer edges yellow ; prothorax 

 j^licated obliquely, cylindrical but not very long ; elytra ampliated 

 past the middle, acuminated behind, with the apical sutural spines 

 short but acute, deeply foveated from the base to a little past 

 the middle, coarsely shagreened from there to the apex, and each one 

 having four slightly wavering raised lines reaching only to a little 

 past the middle, and also a conspicuous marginal, short, white band 

 near the apex. 



The foveas of the anterior part of the elytra are not so broad as 

 those of if. Bertolonii to which it is however closely allied, but 

 Bertolonii has five raised lines on each elytron, whereas costata has 

 only four .2

M. LiMPOPOiANA. new spec. 



Black with a brassy tinge, moderately shining on the upper 

 part, steel-blue underneath ; head strigose, labrum quite black or 



*Mr. Wallengren has no longer the typical example of M. fossulata in his 

 possession, but he writes that so far as he remembers, the facies is that of 

 M. costata, as figured in plate II., fig. 6. 



*The insect figured in plate II. should hare four lines on each elytron instead 

 of two.
