Thesemasses may be found on the trunk of the trees, in crevices of the bark, on the largerlimbs or in sheltered spots, such as fence boards and on bunches of dead leaves hangingupon the tree. In Toronto, the trunks of the horse-chestnut trees attacked presented insome cases quite a spotted appearance, from the innumerable white masses of eggs andcocoons attached to the bark. As soon as the ^^<7S hatch, tiny caterpillars (fig. 51, 6) make their appearance (usuallyabout June), and, as development proceeds, they pass through a series of molts, three—(one ENTOMOLOGICAL SOCIETY OF ONTARIO. 53 a week). After the third, the larva (6g. 55) presents all the striking characters which makeit so readily identified.
