A new species belonging to the unrecorded genus Sinishivophis Zhang, 1982, Sinn'shiuaphis korean n, sp. is described and two unrecorded species of Drepanosiphinae, Pteroca leis (Recticallis) alnijaponicae (Matsumural, and Tinocalfis tokochihoensis (Hisuchi) are reported from Korea.

This study on Pemphigidae was based on the specimens collected from May 1989 to April 1993, at 16 localities of southern part of Korean Penninsula. As a result, 11 species of 7 genera were identified. Of these, four species (Colophina zelkovae, Prociphilus chaenomelis, Tetraneura pumilae, T. iriensis) are new to science. These four species were described and drawn.

Gall development of Nurudea yanoniella on Rhus japonica and emergence of alatae from galls were studied in Jeonju. The galls were formed in late June to late October and slit open in late October 1999. The maximum length and width of galls marked were measured weekly during the period from gall formation to opening. The length and width of galls increased exponentially until mid August. After the 12 September the gall stopped developing Fundatrices (the first generation within the gall) began to larviposit on 24 June and the second generation developed in July to September. The alatiform of the second generation arrived at the final stadium in late September. Consequently, there were at least 4 generations within the galls. Alatae escaped from galls in early October. Correlation between gall and leaf growth indicated that fundatrix might act as a gall forming factor and 2nd-4th generations growing factor. A new species to Korean fauna, Nurudea shirai (Matsumura 1917) was found during this study.

The developmental process of Paracolopha morrisoni's galls on Zelkova serrata until the emergence of alatae from the galls was studied at Chonju, Korea. The galls were formed from late April to early May, 1997 and the galls began to open in early June. The length and width of galls and leaves were measured during the period from gall formation to opening. The length and width of galls have been increased until mid May continuously. The galls stopped growing at 12th of May. Fundatrices (the first generation in the gall) began to larviposit from May 15th and the second generation developed in late May. The alatae of the second generation arrived at the final stadium, that was escaped from the gall, in early June. Thus, there were only 2 generations in the gall. The close correlationship between gall growth and leaf growth suggests that leaf growth force may have a great influence on gall development.

During the period from April to October, 1998 the authors investigated the gall development process of Chinese gallnuts (Schelchtendalia chinensis) on sumac (Rhus javanica) at Mt. Goduk near Chonju city in Chonbuk province. The majority (56.8%) of chinese gallnuts were formed on first pinnates and 24.3% on second pinnates of sumac leaves. Galls began to form from the 1st of June and grew slowly until the 24th of June. Galls enlarged rapidly after the 1st of August, but their growth rates decreased after the 26th of August and stopped growing after the 8th of September. Alate viviparous females escaped from galls after the 24th of September. Fundatricies, the second generation in the galls, exuviated three times to become adults on the 24th of June. Fundatrix adults bore 1∼10 eggs in the body and laid 1∼16 nymphs of the second generation. Nymphs of the second generation began to appear on the 17th of June and had matured completely on the 14th∼24th of July. Adults of the second generation bore eggs in the body. Thus the developmental period of the second generation was 27∼37 days. Nymphs of the third generation appeared on the 14th of July and finally alate viviparous females were developed on the 24th of September. During the two months from the beginning of the third generation to the appearence of the final alate viviparous females, there should be at least two generations, that is, the third and fourth generations. The fourth generation seems to begin at about the 20th August because the number of inhabitants (2,859 individuals) in galls on the 26 th of August had increased more than 10 times those (263 individuals) on the 19 th of August. The tannin content of galls was 65.04∼68.23% while that of sumac leaves and stems was 11.56%, 3.49% respectively.

This study includes the taxonomy , and a key to species of aphids in the family Lachnidae from Korea. Specimens examined in this study were collected from 24 kinds of plants. Samplings were accomplished at 95 localities in Korea from March, 1987 to August, 1994. A list of Korean lachnids are as follows. *1. Chinara atlantica (Wilson, 1919), *.2. C. cembrae(Seitner, 1936), *3. C. formosana (Takahashi, 1924), *4. C. fresai Blanchard, 1939, *5. C. idahoensis Knowlton,1935, 6. c. juniperi (de Geer, 1773), 7.C.kochi Inouye,1939, *8. C. laridicola (Matsumura, 1917), *9. C. laricis (Hartig, 2839), *10. C.longipennis (Matasumura, 1917), 11. C. orientalis (Takahashi, 1925), *12. C. pinidensiflorae(Essig & Kuwana, 1918), *13. C. piniformosana(Takahashi, 1923), *14 C. shinjii Inouye, 1938, *15. c. tujafilina (Del Guercio, 1909), *16 . c. watanabei Inouye, 1970, *17. C. togyuensis Seo. 1994. *18. C. deodarae Seo. 1994, *19. Eulachnus agilis (Kaltenbach, 1843), *20. E. pumilae Inouye, 1939, *21. E. thunbergi (Wilson, 1919), *22. Schizolachnus orientalis (Takahashi, 1924) , 23. Lachnus, Chosoni Szelegiewicz, 1975, 24. L. japonicus (Matsumura, 1917) , *.25. L. tropicalis 9van der Goot, 1916), *.26. Maculolachnus sumbacula (Walker, 1848), *27. M. paiki Seo. 1994, *28 Nipppolachnus piri Matsumura, 1917, 29. Stomaphis asiphon Szelegiewica, 1975, *30. S. japonica Takahashi, 1960, *31. S. yanonis Takahashi , 1918 , *32. Tuberolachnus salignus *(Gmelin, 1790). Of them , 27 species preceded by an asterisk were observed in this study, and keys to these 27 Korean lachnids are provided . The relationship between Korean lachnids and their host plants, and geogrpahical distribution are discussed.
