Hah. — West Australia. Swan Kiver. 



A very distinct species, having the protlioracic tubercles differ- 

 ently arranged, and the elytral tubercles stronger than in all the 

 other species. M. Le'uhhardti approaches it most nearly in these 

 respects; but, inter alia, the colour of the tubercles will prevent 

 their confusion. The central group of tubercles on the protliorax 

 varies in number, and while most specimens possess only a few, 1 

 have seen specimens possessing almost as many as some varieties 

 of M. ins ignis. 



The description given by Hope is very short, and his figure is 

 bad; but both clearly refer to the present species.

Head with middle of concavity triangularly convex. Internal 

 rostral ridges well defined, almost meeting, but separated by a 

 groove. Eyes round. Prothorax(6 x8mm.) rather strongly trans- 

 verse, subangulate on sides in front of middle, central and sul)- 

 lateral spaces smooth, with obsolete hnigitudinal striae; median 

 group of tubercles about twelve on each side, rounded in shape, a 

 large one near a[)ex, followed by a smaller transverse one, and then 

 by an irregular double row of smaller ones; lateral group consist- 

 ing of similar but smaller tubercles mainly situated around lateral
