Fulgora armata, Drury, App. vol. 3.

HABITAT: Cayenne (Drury).

Head extending almost half an inch above the eyes, having many tubercles, like stubbed horns, on the sides, trifurcate at the tip. It is likewise furnished with two short pointed and black horns that are placed directly over the eyes, and two smaller ones a little below them. It appears as if it had four eyes; two fixed, and of a grey colour like horn; just below which the other two (seeming eyes) are placed. They are black and moveable, but are the antennæ, and are perfectly round. Hemelytra dirty green at the base, with some dusky red patches irregularly placed; but near the extremity having a large patch of a dark orange colour. The wings are black, but next the body red, with some red spots in the centre of them. Rostrum horny, lying between the legs, even with and close to the breast. Tongue seeming to proceed from the mouth, and much smaller than the other instrument (labium), being as small and fine as a hair. Feet formed for walking.

There is a confusion in the works of the earlier authors relative to the native country of this species; Linnæus and Fabricius stating it to be India, whilst Stoll records Surinam, Drury, Cayenne, during that it and others figured by him were collected by Mons. Mallouet, {79}who sent them to Europe, but in their passage they were taken by the Shaftesbury privateer, and afterwards sold by public auction, where he purchased them. Donovan states that two specimens he possessed were taken in Brazil; and Dr. Burmeister still more satisfactorily says, "Gleichfalls aus Sud-Amerika findet sich besonders haufig auf den Cautschuck-Baumen (Siphonia elastica)."
