The larval markings are, as a rule, most conspicuous on the the larva is fully fed it scoops out a chamber in the stem, andcovers itself over with the scooped-out chippings. Each larva makesa chamber for itself, and those specimens which are fully fed in theautumn pass the winter in the larval stage, pupate in the spring, andappear as beetles during the summer. The chamber acts as a doublemeans of protection, inasmuch as it minimises the attacks of insect-ivorous birds, and also shields the creature from injuries when theloose bark is removed from the Cocoons o/Pissodes pini on stem ofScots pine (reduced). 78 FOKEST ENTOMOLOGY. The larva is a white, fleshy, legless, wrinkled grub, with brownhead and strong jaws. It generally is in a semicircular form, andabout half an inch in length. The beetle (fig. 75) is dark pitchy-brown in colour, and sparselysprinkled over with yellow scales. The rostrum is longer than thethorax; antennse terra-cotta colour, with darker chib. Thorax roughlypunctured, with a distinct raised middle line ; elytrae deeply punc-tured, broader than the thorax at its base. On each elytron there arefour yellow spots, two in front and two behind the middle. Lengthabout i inch or 8 to 10 mm. Pissodes notatus (Fabr.) It is very doubtful if this insect is so common as entomologistsmaintain.
