Beetles. 740 FASriLY XXXVII.—ELATEKl D.li:.. Kg. 283. X 7. (After Forbes.) ]395 (4279). Agbiotes mancus Say, Joum. Phil. Acad. Nat. Sci.. III. 1S23, 171; JlMd. II, 111. Oblong, siibconvex. Dull brownish- yellow, dusky beneath, siiarsely clothed with short yellowish pubescence; head and thorax often fuscous; tibiae and tarsi paler. Thorax slightly wider than long, sides regularly curved from base to apex; hind angles short, feebly di- vergent; disli with a shallow median line on basal half.

(Fig. 283.) Lake County; frequent. March 26-June 24. Should be found throughout the State. The larva is known as the "wheat wireworm, " and is injurious to corn, wheat and other cereals espec ally those grow- ing in low, wet lands. It is a cylindrical, pale brownish-yellow species, having two conspicuous black circular pits near the front Bg^ margin of upper surface of last segment. (Fig. i |r 284.) It bores into the stems of corn from the time the latter appears above the ground until it is a foot or more high, causing the infested stalks to wither and die. About three years are necessary for the larva to reach maturity, when it pupates in earthen cells. If disturbed by fall plowing, many I'f the pupae or matured beetles are killed. As yet no other effective remedy has been discovered. IS'.k; (42.S0). Agkiotes stabilis Lee, Trans. Amer. Phil. Soc, X, 1S53. 457. Elongate, rather robust.
