The larva or wireworm is pale clay-yellow, except for the head, the first thoracic segment and the last abdominal segment, which are brown; the full-grown wireworm measures 18 mm. in length and 2*5 mm. in breadth, and the duration of the larval stage is probably three years or longer.

Lacon stricticollis, , Fairm., X 4. typical of the Elateridae, and the blunt posterior angles of the thorax serve to identify the pupal stage of this species, as in the other two the posterior angles are backwardly produced as sharp teeth. The pupal stage lasts for 13 or 14 days. The feeding habits of this species seem to be similar to those of S. cinnamomeus, and the control measures recommended for that species would be just as effective for this one. The Predaceous Wireworm (Monocrepidius pallipes, Esch.) (fig. 8). This species has been found only in sandy soils in association with the white grubs of Rkopaea vestita, and has never been observed attacking cane. The larva.
