Larval stage—at least two years. Pupal stage—about six weeks. Larvae in wood in my house (Mr. Watson cut some largesections of trees containing larvae, and kept them in his house underobservation) pupated about end of July or beginning of August,and beetles were found beginning to middle of September. Larvae pupate at end of tunnel, stopping up the tunnel withsawdust, more or less cemented together apparently with saliva. The larvae make a distinct noise when tunnelling, and ejectlarge quantities of sawdust. The larva moves apparently up and down its tunnels, whichare elliptical in shape, and fully i^ in. by f in. in section ( 217). Mature beetles seem to skulk a lot in the old tunnels. In repo
