. Bulletin. Agriculture. Fig. 4.—The California lead-cable borer {ScoMcia declivis) : a. Adult beetle ; h, left man- dible of adult beetle; c, sexual difCerences in adult beetles, a. Enlarged l-SJ times; li, enlarged 26 times; c, greatly enlarged. large from a maintenance standpoint and the cause of the injury had been discovered and made known to the plant forces. It appears from data recently collected that trouble was experienced in Browns- ville, Tex., in 1912, and in Los Angeles, Calif., in 1913. The insect damage was not, however, large in comparison with other causes of cable trouble. In the year ending March 31, 1916, insect injury was reported as the cause of about one-fifth of all aerial cable trouble * During the same period scattered cases of the destruction of fuses by insects were re- ported from several States. In these cases several of the beetles causing the damage were secured and identified as Dermestes lardurius Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
