bearing white and yellow scales, the upper band being interrupted at the 

 junction of the wings ; snout long and thin, with feelers springing from 

 near the middle. Beetles swarm in April and May, and from April to 

 September lay eggs (often in small clusters), mostly under the whorls 

 of 3- to 8-year-old Pines, and in Pine-cones and the bark of sickly poles.

wards, eating sinuous star -shaped galleries in the cambium, which 

 terminate in a pupal-chamber formed in the sapwood. On entering this 

 to pupate, the vacant space is filled up with bore-dust and wood-chips 

 (Fig. 46), and several pupsc may often be found embedded just below 

 a branch-whorl. The beetle emerges by a circular hole in August or 

 later, pairs and reproduces itself, then hibernates from November under 

 moss or in bark-fissures, and reappears for pairing again in April and May.
