Charis melipona, a South American Longicorn of the family Necydalid?, has been so named from its resemblance to a small bee of the genus Melipona. It is one of the most remarkable3 cases of mimicry5, since the beetle1 has the thorax and body densely6 hairy like the bee, and the legs are tufted in a manner most unusual in the order Coleoptera. Another Longicorn, Odontocera odyneroides, has the abdomen7 banded with yellow, and constricted8 at the base, and is altogether so exactly like a small common wasp9 of the genus Odynerus, that Mr. Bates informs us he was afraid to take it out of his net with his fingers for fear of being stung. Had Mr. Bates’s taste for insects been less omnivorous10 than it was, the beetle’s disguise might have saved it from his pin, as it had no doubt often done from the beak11 of hungry birds. A larger insect, Sphecomorpha chalybea, is exactly like one of the large metallic12 blue wasps13, and like them has the abdomen connected with the thorax by a pedicel, rendering14 the deception15 most complete and striking. Many Eastern species of Longicorns of the genus Oberea, when on the wing exactly resemble Tenthredinid?, and many of the small species of Hesthesis run about on timber, and cannot be distinguished16 from ants. There is one genus of South American Longicorns that appears to mimic4 the shielded bugs17 of the genus Scutellera. The Gymnocerous capucinus is one of these, and is very like Pachyotris fabricii, one of the Scutellerid?. The beautiful Gymnocerous dulcissimus is also very like the same group of insects, though there is no known species that exactly corresponds to it; but this is not to be wondered at, as the tropical Hemiptera have been comparatively so little cared for by collectors.
