Four species of armoured scale insects intercepted at quarantine inspection in Japan are recorded, and remarks are made about some taxonomic questions they arouse. One of the species, found on Xanthorrhoea sp. imported from Australia, is identified with Chionaspis xanthorrhoeae Fuller and trasferred to Poliaspis. Another species, on Chamelaucium from Australia, is very close to Poliaspis ceraflora Hardy and Henderson. A third species was collected on cut flowers of Paranomus, Serruria, and Berzelia from South Africa, and is identified with Rolaspis lounsburyi (Cooley). The fourth species, Opuntiaspis sp., was found on cactus fruits from Mexico, and is apparently different from the three known species of the genus.
