It is almost impossible to identify quite accurately the species de- 

 scribed by different authors and included in this genus. 



For a long time only one species, «>., M. tulerculata, De Geer^ (1778) 

 was known ; it was described anew by Thunberg^ (1781), a^d by 

 Fabricius^ (p. 101). One wonders at such a conspicuous insect not 

 having come under the notice of Linnceus. 



Waterhouse, in 1837,* described another (a female), and gave it 

 the name of latipennis. 



Klug, in a monograph of the genus (1849),^ described and figured the 

 male of latipennis^ and also three other species : i.e., herculeana, scabra^ 

 and granulata, and Bolieman in 1848^ had added one species, i.e., 

 tibialis,
