Book Review



This publication represents far more labor than the 88 pages suggest. In order to attack the problem of higher classification in Lachesilla, Dr. Garcia Aldrete had first to differentiate all species available to him. There proved to be many. Smithers' (1967) catalogue of the Psocoptera of the World lists 61 species of Lachesilla. Garcia Aldrete lists 229 species, most of them still undescribed. The undescribed species are listed by letter-number combinations in the higher categories to which they are assigned.
