The distribution of Eucnemidae (Coleoptera) in eastern Fennoscandia
Muona, Jyrki 1994: Itäisen Fennoskandian sepiköiden levinneisyys (Coleoptera, Eucnemidae). [The distribution of Eucnemidae (Coleoptera) in eastern Fennoscandia] – Sahlbergia 1:1-6.
Maps are given depicting the distribution of the eleven false click-beetles found in eastern Fennoscandia. Possible changes in the distribution and/or abundancce of the species are discussed on the basis of known dated records and changes in collecting practices and activity. The data suggest that in the area during this century Rhacopus sahlbergi (Mannerheim) has declined and Hylis procerulus (Mannerheim) increased; Hylochares cruentatus (Gyllenhal) has gone extinct in Finland, but appears to thrive in parts of Russian Karelia. No change seems to have taken place in the occurance of Hylis cariniceps (Reitter). Hylis foveicollis (Thomson) is more frequently encountered than earlier, but this seems to be directly connected with the greatly increased use of window-traps – no change can be seen in catches made by traditional methods. Although collecting activity has increased, the records of the most frequently found species, Microrhagus pygmaeus (Fabricius), have not increased. This may suggest that it is declining in Finland.
New distributional data on some Coleoptera in Finland and Russian Karelia
Muona, Jyrki 1994: Tarkennuksia eräiden kuoriaislajien esiintymiseen Suomessa ja Venäjän Karjalassa (Coleoptera). [New distributional data on some Coleoptera in Finland and Russian Karelia] – Sahlbergia 1:7-10.
The Finnish records of the elaterids Lacon lepidopterus (Panzer) and Melanotus villosus (Geoffroy) and the scolytid Trypodendron proximum (Niijima) are discussed. Both M. villosus and T. proximum are reported from Russian Karelia as well. The buprestid Agrilus angustulus Ratzeburg and the eucnemid Hylis olexai (Palm) are removed from the Finnish list as all the records are based on misidentified specimens. A moderately reliable, previously ignored difference between M. villosus and M. castanipes is pointed out: in M. castanipes the prosternal peg is often more strongly deflexed in lateral view than in M. villosus.
Bombus terrestris auct. new to Finland (Hymenoptera, Apidae)
Pekkarinen, Antti & Erkki Kaarnama 1994: Bombus terrestris auct. new to Finland. – Sahlbergia 1:11-13.
Bombus terrestris auct. is recorded for the first time from Finland from two localities in the town of Helsinki. Usable characters for specific determination are presented. Putative origins of the species in southern Finland and a problem in the nomenclatory are discussed.

Conwntzia psociformis (Curtis, 1834) (Neuroptera, Planipennia, Coniopterygidae), a new species for Finland
Lammes, Tapio 1994: Conwntzia psociformis (Curtis, 1834) (Neuroptera, Planipennia, Coniopterygidae), maallemme uusi laji. [Conwntzia psociformis (Curtis, 1834) (Neuroptera, Planipennia, Coniopterygidae), a new species for Finland] – Sahlbergia 1: 26.
This is the first time that the Conwntzia psociformis (Curtis, 1834), occurring on Quercus robur, is reported from Finland. The closest known occurrences are from southern Sweden and Norway.
New and corrected records on the distribution of Finnish Heteroptera 2
Lammes, Tapio & Rinne, Veikko 1994: New and corrected records on the distribution of Finnish Heteroptera 2. – Sahlbergia 1: 27-28.
New provincial records for 37 species of Heteroptera in Finland are given. Noteworthy is the report of, an endangered species, Aradus truncates, Fieber, from Suonenjoki (PS).
Capnia vidua Klapalek (Plecoptera, Capniidae) from Kuusamo
Kuusela, Kalevi 1994: Capnia vidua Klapalek (Plecoptera, Capniidae) Kuusamosta. [Capnia vidua Klapalek (Plecoptera, Capniidae) from Kuusamo]. – Sahlbergia 1: 29.
Capnia vidua Klapalek (Plecoptera, Capniidae) is reported from the biogeographical province of Regio kuusamoensis, Grid 27E: 7367:602, from a 2nd order stream running under the dense riparian cover of tall coniferous trees. The population is located about 400 km away from previously known stands in northern Fennoscandia.

The map pf distribution in Finland is given. Some ecological and biological characteristics are presented.
