This species is placed in this genus provisionally. It is certainly not a true Asychna. Indeed, almost the only character common to all the species which Mr. Stainton places in this genus is their ornamentation, and in this respect Laverna? gleditschiæella is an Asychna,whilst this species is far from it. This species (pulvella) differs widely enough from all the others in ornamentation ; but structurally it approaches this genus so nearly that rather than construct a new one for it, I place it here provisionally.
