One female specimen from Sunday Island. Mr. Oliver notes that only one specimen was seen during his stay on the island.
The species is widely distributed, and has been recorded from the Cape of Good Hope, Australia, Tasmania, New Zealand, &c.
In his latest work, Stebbing, in deference to the opinions of others, adopts the name Plagusia chabrus (Linn.) for this species, though he had previously argued in favour of P. capensis De Haan. I am glad that it is possible to retain the name by which the species has always been known in New Zealand.
