The pupal stage lasts about 20 days, most of the moths emerging during the first 10 days in July. Weather con- ditions during the spring serve to accelerate or retard the growth of the caterpillars, so that the time of pupation and emergence of the moths varies considerablv. THE ADULTS. (PI. TV, figs. 2, 3.) Both males and females are white and bear a tuft of yellowish-brown hairs at the end of the abdomen, from which the name " brown-tail moth'' is derived.

Both sexes fly more fre- quently at night than in the daytime^ although most of the eggs are deposited dur- ing the day. The moths are attracted to strong light, especially electric arc lights in cities and towns, and. J-IG. -Oak tree in winter, showing webs of the brown-tail moth at tips of branches.

Stores and houses in the neighborhood are often invaded by the moths, and several cases are on record where merchants have been obliged to close their stores during the height of a moth flight in order to prevent annoyance and trouble caused bv the enormous num-.
