This large and remarkable species of winged bug is commonly known in the West Indies under the name of the Wheel-bug, and is stated by Messrs. Kirby and Spence to possess the power of communicating an electric shock to the person whose flesh it touches. "The late Major-General Davies, of the Royal Artillery, once informed me, that when abroad, having taken up this animal and placed it upon his hand, it gave him a considerable shock, as if from an electric jar, with its legs, which he felt as high as his shoulders; and dropping the creature, he observed six marks upon his hand where the six feet had stood."
