The damage is done entirelyby the adult beetles, which areamong the smaller of the May-beetles or June-bugs, measureone-half to five-eighths of an inch long, and are from reddishbrown to nearly black in color. The beetles gouge into the rootsor stems just below the surface of the soil, often ruining the rootfor market without injuring the top. The injury may occur by * Ligyrus gibbosus Dej. Family Scaraboeidoe. See F. H, Chittenden,Bulletin 3:^, n. s., Div. Ent., U. S. Dept. Agr., p. Fi(i. 29U.—TIr- carrut-beetle (Ligyrusgibbosufi Dej.) — much enlarged.(After Forbes.) MISCELLANEOUS GARDEN INSECTS 4L5 hibernated beetles in the spring from April to June or by newlytransformed individuals in late summer or autumn. The life history has not been studied, luit is probably verysimilar to that of Lachnosterna (page 79). Control.—No very satisfactory means of control have beentried in a practical way. It is stated that lime scattered overinfested fields has driven the Ijeetles away. It is evident thatafter the crop is gathered, infested fields should be pastured withhogs, if possible, or plowed deeply, and plowed again in the further study of th(> habits of the pest is necessary beforesatisfactory means of control may be devised.
