Zoological illustrations, or, Original figures and descriptions of new, rare, or interesting animals : selected chiefly from the classes of ornithology, entomology, and conchology, and arranged on the principles of Cuvier and other modern zoologists . ics, and particularly in SouthAmerica, for in Brazil alone I collected near 120 are an obvious and very natural family, though thespecies are as yet but little understood, and not one half ofthem described. I have observed a singular peculiarity in agreat many of these insects, which is, that when they are atrest in the sun, the lower wings are constantly in a quickvibrating motion up and down, as if the insect was rubbmgthem together, more particularly where the two lobes (or ob-tuse tails) of the under wings meet, though what purpose thisis intended to accomplish remains unknown. The upper surface of the wings in the greatest number ofthe Hair streaks (as they are aptly called by English collec-tors) are of various shades of vivid blue, so that the speciescan only be ascertained from the under markings, which areusually very striking and delicate : they are all of a small size.
