Three-Lined Fig-Tree Borer 
379 
owing to a dense covering of fine appressed hairs, is brown and white in 
longitudinal stripes. Two broad brown stripes, punctuated with minute 
orange tufts in longitudinal rows, extend from antennae to the tips of 
the elytra. A median scalloped white to yellowish stripe extends the 
length of the dorsum, ending abruptly at the anterior margin of the pro¬ 
thorax, and two similar lateral stripes extend from near the tips of the 
elytra along their margins to the bases of the antennae. The integument 
beneath the tomentum is a dark amber-brown, finely punctate. The 
surface color of the antennae, legs, and underside of the body is dark 
gray to brown. When first emerged, the general color is a very light 
brown to cream-yellow, with very faint white stripes. 
FOOD OF THE ADULT 
The adult beetles feed upon the tender bark of the smaller fig stems, 
and in captivity, when fed with such stems with the leaves attached, have 
eaten freely of the leaves. During the fruiting season they also feed to a 
considerable extent upon ripe and nearly ripe figs. They have been kept 
in captivity for several months, by feeding them leaves, fruit, and bark 
of the fig tree. 
DURATION OF ADULT LIFE 
The longevity of the adult three-lined fig-tree borer as determined 
upon 24 specimens in 1914-15 ranged from a minimum of about 2.5 
months (75 days) to about 7.25 months (222 days). About one-fourth 
of the specimens lived 3 months or slightly longer, and the average 
length of life of all was 3.7 months. The complete records are given in
