The Large Tolype Moth or Velleda Lappet Moth (Tolype velleda) is a species of moth of the Lasiocampidae family. It is found from Nova Scotia to central Florida, west to Texas and north to Ontario.

The wingspan is 32–58 mm. The females are larger than the males. Males have whitish veins and a broad dark grey subterminal band on their forewings. The hindwings are dark grey, either with or without a whitish median band. Females have similar markings, but are paler and less contrasting. Adults are on wing from July to September in one generation per year.

The larvae feed on various broadleaf trees and shrubs, including Malus, Fraxinus, Populus, Tilia, Fagus, Betula, Prunus, and Quercus species. They are greyish with long hairs. Larvae can be found from June to August.
