land (S. Hungary), the flight period is from June to August (Figs 1-4). Oxyethira flavicornis Pictet, 1834. - Bares, fish ponds, August 6, 1984 4 6 (leg. S.

NÓGRÁDI), August 26, 1984 1 S (leg. Á. UHERKOVICH). In tube in the collection of the Janus Pannonius Museum (Pécs). It is a species of large rivers and stagnant waters. Its distribution is also insufficiently known. All specimens were collected along a fish pond together with Orthotrichia tragetti Mosely (Figs 5-8). Hydroptila lotensis Mosely, 1930. - Magyarszombatfa, May 17, 1983 1 6 (leg. S. NÓGRÁDI), July 26, 1983 1 August 17, 1983 1 o_, August 18, 1983 1 £ (light trap); Szederkény, May 19, 1983 4 6

1 (light trap). In tube in the collection of the Janus Pannonius Museum (Pécs). Its distribution is hardly known. This species lives both in stagnant waters and in large rivers. At the two Hungarian localities: near Magyarszombatfa and Szederkény, there are not such waters but a large Sphagnum marsh and some small brooks with muddy bottom are found there. It seems that this type of running waters is suitable for some species of large rivers (Figs 11-13). Hydroptila simulans Mosely, 1920. - Szederkény, May 19-23, 1983 5 Í , 6 j (light trap). In tube in the collection of the Janus Pannonius Museum (Pécs) and the Hungarian Natural History Museum (Budapest). It is a widely distributed species in Europe, eastward to Afghanistan. Its biotopes are smaller or large rivers. Near to its locality (Szederkény), there is the Karasica stream, a slow running water with muddy bottom, meandering amongst hills. The genitalia of the male perceptibly differs from Hydroptila lotensis or H. spar sa (Figs 14-17). The females of H. simulans and H. lotensis are very similar to each other, their distinction is rather uncertain. Hydroptila tineoides Dalman, 1819. - Magyarszombatfa, May 17, 1983 1 o. (leg. S.

NÓGRÁDI), July 27, 1983 1 S , August 2, 1983 1 6 , August 12, 1983 1 o_ (light trap). In tubes in the collection of the Janus Pannonius Museum (Pécs). It is a widely distributed and common species all over Europe living in all types of waters. Therefore it is surprising that it has never been collected in Hungary before. Its genitalia is very characteristic (Figs 9-10), they cannot be confused with any of the other species. Hydropsyche guttata Pictet, 1834. - Szó'ce (W. Hungary), July 28, 1983 1 6 (leg. Á. UHERKOVICH). Pinned in the collection of the Janus Pannonius Museum (Pécs). The old literature data concerning the species of Hydropsyche guttata group are unreliable as it has been proved by MALICKY (1977), ÚJHELYI (1982) re-examined his material but he did not find specimens of H. guttata

. The collections of the Hungarian Natural History Museum, Budapest and of the Janus Pannonius Museum, Pécs housed no specimens. Although this species was published three times in recent years (KISS 1979, 1980, 1981), these data are not supported by voucher specimens. The unique specimen of this species was discovered amongst several dozens of specimens of different Hydropsyche species. Further, about one thousand males were captured and reviewed from West and South Transdanubia, still only this single one was found to belong to this species. The determination was supervised by Dr. H. MALICKY, who verified it (Figs 18-22). Micrasema setiferum Pictet, 1834. - Bares, fish pond, May 4, 1983 1 6* (leg. Á. UHERKOVICH). In tube in the collection of the Janus Pannonius Museum, Pécs. BOGA (1936) published the occurrence of Micrasema minimum McL. in the brook "Aszófó'ipatak" (running to the Lake Balaton) by reason of collecting larvae. The first Hungarian Micrasema adult was collected along the fish ponds nearby Bares. This caddisfly proved to be Micrasema se tiferum Pictet. The species occurs sporadically in Europe, it lives in rivers and streams.lt could not be decided where the larvae developed, either in the Drava river or in the stream "Rigóc-patak". Only a single specimen has been known up to now from Hungary (Figs 23-25). Oecetis testacea Curtis, 1834. - Magyarszombatfa, July 1-15, 1983 3 Í, 2 j (light trap). In the collection of the Janus Pannonius Museum, Pécs. This species, occurring both in standing and running waters, is known all over Europe, notwithstanding some of its data are dubious. It has only been found in West Hungary (Figs 26-29). Setodes viridis Fourcroy, 1785. - Magyarszombatfa, June 13-July 19, 1983 31 ô*

, 9 j (light trap). In tubes in the collection of the Janus Pannonius Museum (Pécs) and of the Hungarian Natural History Museum (Budapest). PILLICH (1914) has mentioned this species from Simontornya (Central Hungary), but no voucher specimen is known. The first authentic specimens (40!) were found in the material of a light trap operating at Magyarszombatfa (W. Hungary). The genitalia of both sexes are highly variable (Figs 30-35).
