On a new genus of Psyllidæ from Nyasaland

Extract

The remarkable insect herein described belongs to the family Psyllidæ, of which relatively few species have hitherto been recorded from Africa. The pupa? (and possibly also the larvas) cover themselves with dense masses of white flocculent or wool-like wax, the separate strands of which are sometimes over one inch in length. These flocculent coverings are arranged together in large patches on both the leaves and stems of the food-plant so that they are thereby rendered most conspicuous. The habit of secreting coverings of white wax is common to many members of this family of the Homoptera; but the great length to which it attains in this species is quite exceptional and noteworthy.
