One of the common smaller species is the red-necked blackberry-borer. It is a third of an inch long, with black wing-covers, dark bronze head, and coppery bronze prothorax. The larva bores in the sapwood of the rasp- berry and blackberry, causing a gall-lik^ swelling, and when full grown bores into the pith, where it pupates. m^ The fireflies {Lampyri- dae) which twinkle in the dusk of a warm summer evening are not realh' flies, but beetles, though their bodies and wing- covers are much softer in texture than those of most beetles Fic. ::oS.
