In M. regalis (Bob.), from JN'atal, the dorsal tubercles are elongated 

 or ridge-sbaped ; in M. Bevoili tbey are more widely spaced, and in 

 M. exceha tbe elytra are rougbly punctured, with the intervals ele- 

 vated into rather flat tubercles only towards tbe base, the apical area 

 being nearly smooth.

I have compared this fine species with J), gigantea, from Xatal, 

 as being better known ; it is more closely allied, however, to T>. Mauchii 

 (Bates = D. Oatesii, Westw., in Gates' Matabele-laud, p. 359), both 

 differing from D. gigantea in the thorax being longer and narrower, 

 with its lateral margin more obtuse and gently curved, without 

 angles: in these respects both stand midway between D. gigantea and 

 D. limhata (Bertoloni). D. purpurascens differs from D. Mauchii in 

 its purplish-coppery elytra, the shining raised lines of which are all 

 longer, reaching within a short distance of the apex ; the first, at 

 least, as long as the four others. The short streak or elongated spot 

 on each elytron is distant from the base in D. pupurascens. The 

 labrum is black, with a tawny-white central vitta in both sexes. The 

 joints 5—10 of the antennae are very much wdder than in D. gigantea 

 and the elytra more ovate, in both sexes gradually narrowing to the 

 base, with obsolete shoulders.
