This drawing is from Guérin-Méneville (1829). He labeled it Gelasimus Duperreryi, a species now known as Gelasimus tetragonon. He later used this same image in another work (1829-1844) but labeled it as yet a different species, Gelasimus chlorophthalmus, (the label of which is incorrect; characteristics of the drawing imply it is is Gelasimus tetragonon).
