The effect of this change in theposition of the ornaments is to invert the insect in appear-ance. The species that have these tufts behind are remark-able for their very long hind-legs ; and these, held straightbehind them, appear very much like antennae. Small moths [Pyralidce, Toitricidce, Tinceidce^ sit onleaves, with their wings folded over their backs. In this. Longicorn Beetles.* position, many of the species resemble sticks, moss, bird-droppings, etc.; other kinds appear inverted, like the narrow-winged kinds, when at rest, are very muchlonger than broad ; and some of these have a singular habit *The specimens are represented as somewhat magnified ; they would be morepropeily represented on a log or tree, as they are very rarely seen upon theiground. ZOOLOGICAL GLEANINGS. 22$ of spinning about on the leaf when alarmed, moving the bodyrapidly around the head as a pivot. One genus that has thishabit, is marked by a bright red head ; but one or two ofthe species have the head plain, and red spots on the endsof their wings—i. c, on the ends of their tails as they sit onthe leaf; these species spin about their tails instead of theirheads. All these cases point to one supposition. The insects, forsome reason, derive an advantage from apparent inversionof the two extremities of the body. Now,
