For a considerable time it has been known that a representative of the archaic Homopterous family, the Peloridiidae, occurred on Lord Howe Island since a single nymph has been recorded from there (Bergroth, 1924).
This had been collected by A. M. Lea. Although during the intervening years several entomologists have visited the island, so far as is known no additional specimens have been collected. This is not surprising, as the insects are seldom found unless specialIy sought.
Because of their particular interest and because of their significance from the point of view of zoogeography, a visit was paid to the island during March, 1959, specially to search for these insects.
