This study is based on crane fly specimens collected more than 80 years ago in 1938-1939 and preserved at the United States National Museum, Smithsonian Institution, Washington DC, USA. Despite many attempts with a variety of methods, no additional specimens of this genus were captured. This likely means that that this genus is extinct on the Korean Peninsula, or its distribution is restricted to the northern areas of the Democratic People's Republic of Korea (North Korea). The genus Prionolabis Osten Sacken, 1860 with four species, one of them Prionolabis dis(Alexander, 1950) endemic to North Korea, was recorded by Ch. P. Alexander (Alexander, 1938, 1940, 1950). All succeeding papers listing these species were based on these original works without study based on actual specimens. For each species, we present general information on genus, redescriptions of species based on Korean specimens, illustrations of important taxonomical structures, elevation range, period of activity, habitat information, general distribution, and a distribution map for the Korean Peninsula.

Objectives : We have examined the relaxational response to the water extract of genus Panax in rat thoracic aorta and mesenteric artery. Methods : Segments of thoracic aorta and mesenteric artery obtained from rats immediately after delivery were mounted in organ baths superfused on a polygraph. Results : We found that the thoracic aorta segments responded to the water extract of genus Panax with a dose-dependent vasorelaxation. At $10^{-5}m$ 5-hydroxytrptamine (5-HT), the maximal contraction force were 94.9% of the maximum KCl-response. At $10^{-5}m$ 5-HT - induced contraction, The contractile response of thoracic aortic rings were inhibited by 54.7%, 36.3% and 31.3% after addition of the high concentration (100 mg/ml) of water extract of Panax ginseng, Panax japonicus and Panax quinquefolium. The contractile response of mesenteric arteries were inhibited by 88.3%, 87.7%, and 70.3% after addition of the high concentration (100 mg/ml) of water extract of Panax ginseng, Panax japonicus and Panax quinquefolium. Conclusions : In conclusion, water extract of genus Panax - induced relaxation in the isolated rat thoracic aorta and mesenteric artery were composed of endothelium - independent relaxation and dose - dependent relaxation.

The genus Metopius is a relatively large ichneumonids group that includes 145 species worldwide. In this genus, 41 species have been reported from the Eastern Palaearctic region, while eight species have been reported from Korea. We reviewed Korean species of the genus Metopius and confirmed 13 species. We also report five species, Metopius (Ceratopius) maruyamensis Uchida, 1930, Metopius (Ceratopius) scrobiculatus Hartig, 1838, Metopius (Peltastes) fossulatus Uchida, 1933, Metopius (Peltastes) pinatorius $Brull{\acute{e}}$, 1846 and Metopius (Peltastes) sapporensis Uchida, 1930, which were recorded for the first time from Korea. A key to Korean species of the genus Metopius, redescriptions of newly recorded species and digital images of Korean Metopius are also provided.

The genus Oithona was investigated taxonomically in samples collected from 10 regions of the Korean waters. In result, 18 species of the genus Oithona were identified, and a key table on 18 species was given. Of these following nine species were new records for Korean waters: Oithona atlantica, 0 . attenuata, 0 . davisae, 0. hamata, 0. longispina, 0 . oculata, 0 . simplex, 0. tenuis, 0. vivida.

The genus Sciasmomyia (Diptera: Lauxaniidae) was discovered for the first time in Korea. This Old World (PA and OR) genus currently includes two nominal species. In the process of revising Korean Lauxaniidae, we were able to collect Korean representatives of Sciasmomyia supraorientalis, and provide the redescriptions and illustrations of both sexes.

A geometrid genus Pareulype Herbulot sensu Inoue (1977) is reviewed in Korea. Up to now, two species, P. taczanowskiaria (Oberthur) and P. onoi Inoue, were known from Korea and these two species were newly combined into another genus Pelurga Hubner. One Pareulype species, P. consanguinea (Butler), is first recognized from Korea throughout the present study. Diagnoses of each genus and species are provided with illustrations of adults and genitalia. Phylogenetic relationship of Pareulype and Pelurga Hubner is briefly discussed.

Taxa of genus Callicarpa in Korea were described taxonomically and studied interspecific relationships, based on the leaf length, leaf width, peduncle length, fruit width and geograhic distribution. Among 12 taxa reported previously in Korea, 3 forms of C. japonica were unifed to original species, C. japonica var. glabra was reserved, Whereas C. shirasawana was not distributed in Korea. As a result, 7 taxa belonging to 3 species, 4 varieties of genus Callicarpa remained. C. japonica complex is considered to be more advanced among the species compared with the bract shapes.
