Key words. -Cryptus, Canary Islands; new species. G. van Rossem, Berkenlaan 25, 6711 RM Ede, The Netherlands. Introduction Two consignments of material from the Canary Islands, received from Dr G. Ortega ( Museo Insular Ciencias Naturales, Tenerife) gave me the oppor-tunity to study Canarian specimens of the genus Cryptus Fabricius, 1804. Dr Kl. Horstmann (Zoo-logisches Institut III, Würzburg) kindly offered me to insert specimens from his collection and one specimen from the Museo Insular at Tenerife. Dr Horstmann also acted in my interest by asking for the loan of the type material of Cryptus nigritarsis Kriechbaumer at the Transvaal Museum at Preto-ria (RSA). Dr Max Fischer (Naturhistorisches Mu-seum Wien) sent the type specimen of Cryptus verutus and Dr F. Koch (Museum für Naturkunde, Berlin, DDR) put the type specimen of C. verutus subsp. bierroensis at my disposal. Dr Roy Daniels-son (Universitetets Zoologiska Institutionen, Lund, Sverige) granted me the permission to study the type of Cryptus obscuripes Zetterstedt and sev-eral other specimens of that species and of Cryptus dianae Gravenhorst as well. With respect to the use of the name Cryptus the author refers to Van Rossem (1987). Townes ( 1970: 193) provides a description and a figure (fig. 165) of Itamoplex Förster, a junior synonym of Cryptus Fabricius. In due time the collection Van Rossem will be placed in the Rijksmuseum van Natuurlijke Histo-rie at Leiden.
