The egg tunnels are about % inch wide, although the width is very irregular in the different parts of the tunnel. In an egg-tunnel recently started, the half nearest the entrance hole will be packed tightly with chips and excrement, and in the distal—empty—half will be found the beetles, a pair or more. In some I have found one female and as many as three males. As the tunnel is lengthened, the refuse, chips and excrement, is packed towards the entrance, leaving always a short, clear space at the distal end. As the tunnel increases in length, shallow pockets I.
