Data about finding places of 444 species of insects (Heteroptera 74, Homoptera 19, Coleoptera 114, Hymenoptera 78, Diptera 114 and Lepidoptera 45) in 1708 specimens are given. These specimens were collected in the period of 1969 to 1972 on 75 locations in different forest communities of Croatia. Therefore this represent a complement to the work done earlier in forest communities in Croatia.

The Heterocera in the Igalffy Collection of the mountainous areas of Risnjak (Gorski kotar) and Licka Pljesevica (Lika) (leg. K. Igalffy) contain 127 taxa. In the Macrolepidoptera group. We have established 17 families of moths. The greatest number from Geometridae families, 44 species and Noctuidae, 29 species. Fifty nine species (Heterocera) were recorded in the Risnjak National Park. Seventy eight so far unrecorded species were established in the Licka Pljesevica. Together with the number cited in the literature this totals 164 registred species of Heterocera fauna for this mountain. According to available literature, in the central-mountain part of Croatia, 22 unrecorded species were established, for Gorski kotar 5 and for Lika 59. According to this data the degree of research of Macrolepidoptera fauna in the central-mountain area of Croatia is 55-65%, for Gorski kotar 65-75%, for area of Lika 35-45%, for mountains Lic ka Pljesevica 25-30% and Risnjak 10-15%, while data about Microlepidoptera is negligible. To demonstrate the characteristics of Macrolepidoptera fauna we made analysis of noctuids fauna for the areas of Gorski kotar, Turopolje and southern Dalmatia. Zoogeographical analysis shows that the domination of Eurosiberian species which is based on the ecological characterystics. The high percentage of the Oriental species is the result of the Mediterranean influence on this region and faunal migration some species of moths.

Pyritized bauxite was exploited in the valley of Mirna river in Istria already 400 years ago. It was used as a raw material for production of vitriol and alum. The pyritized bauxite contains both pyrite and marcasite. The conditions of their formation are interpreted in terms of the pH of the micro-environment and the concetration of sulfur and iron. Tho phases of pyritization of bauxite have been recognized. Sulphur from the first phase of pyritization originated from organic matter of hangingwall sediments, while during the second phase sulfur mainly originated from the sea water. Pyritization is in some places accompained by diasporization.

During gravel exploitation from the river Sava near Zupanja an isolated bovine atlas was found. After palaeontological study (morphometric characteristics, brown colour, strong petrification) it was determined to pertain to the Upper Pleistocene bovines (Bison seu Bos). Detailed anatomical, metrical and radiological comparison was made between the fossil atlas from Zupanja and the atlas of the recent Istrian cattle (Bos taurus primigenius), which is the representative of the most primitive primogenetic bovine form, osteologically completely akin to the original fossil species Bos primigenius. Using the literature data both atlases were metrically correlated with the atlases of the following fossil and recent species: Bison priscus, Bison bonasus, Bos primigenius and Bos taurus. It was not possible to determinate the fossil atlas generically, while the recent one is well defined. All analyses indicate that problems concerning the identification of isolated atlases, which were hitherto studied on the fossil and recent bovine species mentioned above, are equally expressed both on the fossil atlas from Zupanja as well as on the atlas of the primitive recent Istrian cattle species (Bos taurus primigenius).

In this paper the locality is reported of the subspontaneously spread East Asian pteridophyte Cyrtomium falcatum (L. fil.) C. Presl, a new species in the flora of Croatia, found in the town of Rab on the island of the same name. During several years follow-up this fern has been found to survive for more than 10 years growing wild and slowly spreading new surface areas.

In the course of ten years, the Eastasiatic species Sedum sarmentosum Bunge, has been found growing in Croatia. It grows in antropogenous gravelled and sandy habitats and in old walls. It always appears alone, and not inclined to join other plant species. The plant was introduced in Europe as an ornamental plant cultivated in gardens, but escaping from culture, it expanded as a wildgrowing plant, probably carried by animals (such as birds or ants) or transported with building materials. In Croatia the fructification of this species has not been noticed.
