Distinguished from its nearest ally M. phitlna by the rela- 

 tively longer elytra and the colour, which is dark brassy (slightly 

 golden) or coppery brown, sometimes inclined to purple. The 

 majority of examples compa,red also differ in the more glabrous 

 surface, both of thorax and elytra ; the parts clothed with thin 

 pile and minutely punctured are here of much smaller area, and 

 the elytra are sometimes entirely naked and tolerably strongly 

 punctured throughout, the thorax in the same examples being 

 nearly impunctate. The posterior corners of the disk of the 

 latter are sometimes strongly Avrinkled.

Distinguished by its transversely wrinkled thorax. The ruga? 

 are slightly waved and extend (with interruptions in the lateral 

 and anterior depressions and on the dorsal tubercle) to the fore 

 and hind margins and the lateral spines. The elytra are pretty 

 evenly and not closely punctured throughout. The colour is a 

 splendid golden-green, more brassy on the under surface.
