Donovan states that the insect here figured inhabits China and every other part 

 of India. Linnaeus, however, referring to Gronovius and Sloane's Jamaica, gives 

 America as the locality of his G. acuminatus ; whilst Fabricius says, " Habitat in omni 

 India et in Europa Australi." In this confusion of locality, I have thought it best to 

 mark the specific name of this figure with doubt.
