Insects affecting the orange . Flo. 79.—CremastognuterUneolata: a, 6, woikermajor; c, head of do.: d, female; e, wiuj;;/, worker minor. (After McCook.) INSECTS FEEDING ON 15AKK AND DEAD WOOD. 171. THE ORANGE SAWYER. {Elaphidion inerme Newman.) This insect has been described in Chapter VIII, and is there shown tobe injurious, under a careless sys-tem of pruning, in which the endsof branches are left untriramed,with suflBcient dead wood to at-tract the parent beetle, but notenough to support the larvae; sothat the latter are driven by hun-ger to enter and feed upon the liv-ing wood. It appears, therefore,that under natural conditions thisbeetle is merely a scavenger. Itsgrub feeds upon the wood of manytrees, and, like most members ofthe Longicorn family, thrives onlyupon diseased and devitalized tis-sues, or upon wood which, thoughdead, has not entirely parted withits sap and become hard and dry. Fig. 80 represents the larva ofU. parallelum, a closely allied spe-cies, having the same habits as the Orange Sawyer, but which lives iuthe Oak, &c.
