Doryphora dor.

The Colorado Potato Bug. Coleoptera.
"This insect belongs to the same family as the squash bug, the black potato bug, and the Cantharides-all possess the power of blistering the skin if bruised upon it. The Colorado potato bug has its original home in the Rocky Mountains, where it fed on a species of Solanum indigenous to that locality. It got a taste of the Solanum tuberosum, the common potato, and rapidly traveled East, until it reached the Atlantic". Hale's Symptomatology .
The tincture is prepared by crushing the live beetle and covering it with alcohol. Provings by Ruden and Jerkins, see Allen's Encyclopædia , v. 4, p. 167 .
