The present report deals with the material of Collembola collected during a Lund University Expedition in 1957 to the Azores and Madeira, by Dr. and Mrs. Per Brinck and Dr. and Mrs. Erik Dahl. From late February to the middle of April1957, the expedition investigated six of nine islands of the Azores, viz. Santa Maria, Sao Miguel, Terceira, Pico, Faial and Flares; at the end of April 1957 the main island of Madeira was visited. I. Previous work on the Collembola of the Azores and Madeira From the Azores only eleven species of Collembola have previously been recorded: Smynthurus fuse us L. ( = Allacma fuse a [ L.]), Macrotoma tridentifera Tullb. ( = Tomocerus minor [ Lubb.]), Templetonia major Mo niez ( = H eteromurus major [ Moniez]),? Lepidocyrtus lanuginosus Gmel. ( = ? a young Entomobrya), Isotoma tullbergi Moniez ( = Isotomurus pa lustris [ 0. 'F. Mull.]), Entomobrya multifasciata Tullb. ( = E. nivalis [ L.]), Xenylla humicola 0. Fabr. nom. dub. ( = X. maritima Tullb.), ? Anuropho rus sp. ( = ? Uzelia setifera Abs.), Lipura agilis Moniez ( = Onychiurus ambulans [ Nic.]), Lipura bipunctata Moniez nom. dub. ( = Onychiurus ghidinii Gis. an 0. pseudinermis Born.?). All these species were recorded by Moniez (1889). Finally, Stach (1951) mentions Neanura . muscorum (Templ.) from the Azores. Our knowledge of the Madeiran Collembola was, on the other hand, relatively advanced when I began to write the present report. Thanks to the work done by Agrell (1939), Delamare Deboutteville and Bassot (1957), Gisin (1958) and Gama (1959), the list of identified Collembola previously recorded from Madeira contained about 60 different species.

The above list is, of course, not free from misidentified species which are discussed in the following part of the present paper. All the material examined has been mounted in polyvinyl alcohol and returned to Lund where it will be deposited in the Entomological Museum of the Zoological Institute. I am indebted to Professor P. Brinck, Lund, who sent me the rich col lection for study, as well as to Dr. L. Hoberlandt, Prague, who agreed to publish the present paper in this journal. II.

A cosmopolitan species, the polymorphism of which was described excellently by Gisin (1947, Mitt. schweiz. entomol. Ges. 20: 342). Later in 1958, the same author proposed the Madeiran populations to be named • H. (Ceratophysella) occidentalis Gisin. A number of Azorean specimens which I investigated in detail with regard to their abdominal microchetotaxy correspond to the type u occi dentalisJJ, but owing to the known variability of the characters in ques tion I am opposed to classify the form u occidentalisJJ as a distinct species or subspecies. In addition, the Azorean populations show some colour differences. Thus the examples listed as AZ/7/2, AZ/11/3, partly also AZ/-/3 (3 ex.) and AZ/35/1 (3 ex.); may be identified as f. uunicolorn; those listed as AZ/78/3 rather represent f. upallensn.
