A revisionary study of the taxon Cillenus Samouelle, 1819 and related forms (Coeloptera: Carabidae, Bembidiini)

The 23 species of Bembidiini revised in this paper were earlier referred variously to subgenus (or genus) Cillenus Sam. or to closely allied taxa. It is shown that the five New Zealand species are taxonomically quite isolated and different from Bembidion; for these the new genus Zecillenus was erected. All remaining species are true members of genus Bembidion belonging to five different subgenera, all previously named. Subgenus Desarmatocillenus Netolitzky contains 13 species distributed from Tasmania to Japan; three other subgenera are restricted to China, Formosa and Japan, respectively. The single European species, B. laterale Samouelle, constitutes subgenus Cillenus s. str.—Six species, Zecillenus embersoni and 5 Bembidion, adelaideae, foochowense, hebridarum, kasaharai, seticorne, are described as new.—None of the subgenera shows clear affinities to any other subgenus of Bembidion. This was judged primarily on the structures of the internal sac of penis.

Scandinavian entomologists 5 - Karlis Princis

A short biography of Karlis Princis (1893-1978) is given by Lindroth. A complete list of his entomological publications is compiled by Gurney together with a list of the 62 new genera and 365 new species described by Princis.

Functions of entomological collections

It is emphasized that, though the primary goal of an entomological museum is to serve as fundament for taxonomic research, new and important branches of entomology have added other duties. Studies in biogeography and in analyses of infraspecific variation require storing of virtually unlimited samples of the natural populations. And all information on the ecology of species, in form of journals, diaries, correspondence etc. of the collectors, should be carefully preserved and arranged so as to permit exact reference from the insect specimen. It is also a duty of the museum to initiate the preservation of base material used in, for instance, physiological and genetic research.

Melanistic forms of Calathus melanocephalus L. in Iceland (Coleoptera: Carabidae)

Calathus melanocephalus is always more or less melanistic in Iceland. Tests were carried out to determine whether the degree of melanism was causally correlated with weather conditions during the immature stages. Samples from the same area collected in different months and years were compared. The correlation betweeen melanism and weather was slight, or even absent. A comparison of samples from different parts of Iceland showed a clear predominance of pale individuals in the east. This can only be explained as being due to genetic differences between populations.

Scandinavian entomologists I - Per Benander

A short biography of Per Benander (1885-1976) is given together with a complete bibliography of his entomological papers. He described 22 new species of Lepidoptera, of which 11 species still are valid. A list of the species and the synonymy is presented.

Revision of Haematopota Meig. in North Europe (Dipt. Tabanidae)

The species of the genus Haematopota Meig. occurring in Denmark, Sweden, Norway and Finland are revised on the basis of all accessible material including types from various museums and private collections. Keys to, and short diagnosis, figures and notes on synonymy and distribution of, the six species involved are given. Four lectotypes are designated and three new synonymies are established. The difficult hispanica-group is discussed in an appendix.
