The Acoro-Glycerietum maximae association has so far been known in the vegetation of Croatia from two localities: Topolovac and Buda{evo near Sisak and the Krapje |ol Ornithological Reserve near Jasenovac. During phytosociological analysis of aquatic and marsh vegetation in Slavonija, a third locality was discovered in Babina Greda, where it covers the banks of the Berave stream.

This paper describes the finding of a new locality of the Mediterranean species – Narcissus serotinus L., on area of Pelje{ac Peninsula, near village of Lovi{te in Mirce Bay, over quite a large area. Previous mentions of Narcissus serotinus L. in the Dalmatian flora (Croatian) and Bosnia and Herzegovina, Yugoslavia, were based on a report from the session »Zoologisch – botanischen Gesellschaft in Wien« of 1861, which is quoted in its entirety in this work. According to this report, mentions of this species in the flora of Bosnia-Herzegovina were dubious, and the localities in Croatia were not precisely indicated. Researchers into Croatian flora do not quote this species in their works. This is the first certain finding of this species in the Croatian flora.

This work presents a third revision of the inventory of butterflies of Bosnia and Herzegovina according to the Karsholt – Razowski system. The revision was carried out from analysis of the scientific literature and published field observations from B-H. The presence of L. reali (Reissinger, 1989) has been verified personally by the author in the course of his own field research and subsequent laboratory investigations.

Five species of epiphytic lichens from Risnjak National Park (Candelariella reflexa, Chaenotheca brunneola, Placynthiella icmalea, Usnea diplotypus and Usnea subfloridana) are reported for the first time in the Croatian lichen flora. For each species, a short description with notes on ecology and distribution are given.

In the entrance of Ledena Jama pit, located on Velebit mountain (Croatia), flora and some ecological factors were investigated – momentary light intensity, daily air temperature and humidity during vegetational seasons in 1995–96. In consequence of the collected data, the entrance was divided into three zones. In the first two zones (+6 m to –23 m) it is mostly spermatophytes (122 species) and pteridophytes (5 species) that grow, while in Zone III (down to –40 m) most of the plants are bryophytes and algae. With each species, ecological values according to Landolt were associated: F – humidity value, L – light value, T – temperature value and W – life form. By analysing these values division into zones was confirmed. It was also established that the first two zones, as well as in composition of plant species, also vary in air temperature and humidity, soil moisture and light, which is reflected in the larger proportion of geophytes and alpine species present in Zone II.

Between 1997 and 1998 the breeding density, nest sites, clutch size and egg dimensions of the magpie (Pica pica) was investigated in a 7 km2 area in the Krapina river valley. We recorded a high breeding density of 4.79 pairs/km2 (during both years). The nests were situated at a height of 1–16 m above ground (mean = 6.74 m). Magpie nests were found in at least 9 species of bushes and trees. We recorded 3–8 eggs in the first clutch (mean = 5.91 eggs). Egg length averaged 33.43 mm, egg breadth 23.35 mm, egg volume 9.288 cm3, egg shape index 1.433 and egg weight 9.22 g. There were no significant differences in egg dimensions between 1997 and 1998 (length: F = 1.79, p = 0.10; breadth: F = 1.41, p = 0.34; volume: F = 1.27, p = 0.52; shape index: F = 1.10, p = 0.78). The positive correlation between egg volume and egg breadth, egg volume and egg length, egg length and egg shape index as well as between egg length and egg breadth were statistically significant. So was the negative correlation between egg breadth and egg shape index. The correlation coefficient (r) between egg volume and egg shape index was near 0.

Four specimens of Citrine Wagtail Motacilla citreola were trapped in 1997 at the lake Vransko Jezero, north Dalmatia, three during May and one in September. These represent the first two national records of this Asiatic species in Croatia.

Croatodirus, new genus, bozicevici new species (Coleoptera, Cholevidae) are described from the cave Cavern in U~ka Tunnel, Mt. U~ka (Monte Maggiore) near the town of Rijeka (Croatia). The new taxon, provisionally attributed to the phyletic lineage of Antroherpon, is however markedly isolated owing to the following peculiar combination of morphological features: 1) antennal insertion on the posterior 4th of the head; 2) antennomere 1 slightly longer than antennomere 2; 3) pterothorax not pedunculate, mesosternum not carinate; 4) mesocoxal cavities contiguous; 5) tarsal claws widened; 6) protibiae without external apical comb of spines and without external spurs; 7) meso- and metatibiae furnished with inner, unified spurs; 8) aedeagus medium sized, with inner sac without sclerotized pieces; and 9) female stylomeres and spermatheca fully atrophied. The systematic position and the peculiar ecology of this new, exceptional troglobiontic beetle are illustrated and discussed.

Phoxinellus dalmaticus, new species, is described from the ^ikola River in the Krka River system in Croatia. It is distinguished from congeners by a suite of characters which includes a naked body with scales only in a relatively short, often interrupted, lateral line series (sq. l. 18–44) formed from both pored (l. l. 16–29) and unpored scales, a low number of vertebrae (37 or 38 total) with 21 vertebrae in the abdominal and 16 or 17 in the caudal region, a shallowly forked caudal fin with considerably rounded lobes and the lack of a foramen between the cleithrum and coracoid.
