SHEATH-WINGED INSECTS 28s The Leaf-?IORNED Beetles are distinguished by the fact that the terminal joints of the antenna; he one upon another hke the leaves of a book. In nian_\- cases they can be expanded at will into a broad fan-like club. The well-known S I'.VG-HEETLE is a representa- tive of this group. It is a somewhat local species, being plentiful in some parts ot the country, and entirel)- unknown in others. The grub lives for se\eral \'ears in the trunks ot elm-trees, feeding upon the solid wood. When fully grown, it buries itself in the earth, and constructs a large cocoon, in which it passes the chrysalis stage ot its existence. The perfect beetle emerges in November, but remains within the cocoon until the following June. In the female the jaws are very much smaller than in the male, but are nevertheless more formidable as weapons. The insect may often be seen flying on warm summer evenings. A still larger insect belonging to the same group is the HERCULES BeeT[,E, found in the West Indies and tropical America, a male of average size being nearh' 5 inches in length. In this beetle the thorax is prolonged into a horn, which is curved downwards, while the head is produced into a similar horn curved upwards, so that the two look like a pair of enormous jaws. It has been stated that these horns, both of which are furnished with tooth- like projections, are empIo}'ed in sawing off the smaller branches of trees, the beetle grasping.
