Out of 24 species, 5 species, Stran- galiella emotoi, Idiostrangalia quadrisignata, Rosalia (Eurybatus) nakanishii, Glaphyra shimai and Rhaphuma nishidai are described as new and 6 species, Xylotrechus quadripes Chevrolat, X. incurvatus contorsus Gahan, Chlorophorus shoreae Gardner, Rhapkuma fulgurata Gahan, Aglaophis fasciata Thomson and Artimpaza obscura Gardner are recorded from Nepal for the first time. The Cerambycidae of Nepal have been rather poorly known to science since Hope (1381), in comparison with the surrounding regions such as Sikkim, Assam and Burma or even Kashmir and Bhutan. Recently Villiers et Ch,fijB (1966) and Hayashi (1979, 1980) have contributed toward the knowledge of the Nepalese Cerambycidae based on the material brought back by Japanese expe- ditions. This paper reports the results of our study on the material of the sub- families Prioninae, Lepturinae and Cerambycinae of the family Cerambycidae taken by the Kyushu University Scientific Expedition to the Nepal Himalaya in 1) Contribution from the Entomological Laboratory, Faculty of Agriculture, Kyushu Univer- sity, Fukuoka (Ser. 3, No. 99). 2) Results of the Kyushu University Scientific Expedition to the Nepal Himalaya.

MAKIHARA 1971 and 1972. It includes 24 species, of which 5 species are described here as new to science, and 6 species are recorded from Nepal for the first time (indicated by an asterisk). The material was collected by the members of the expedition; A. Naka- nishi in 1971, and H. Shima, Y. Nishida, J. Emoto and H. Makihara in 1972. Their collecting routes are from Bogara to Dobang, Central Nepal in 1971, and from Biratnagar to Thudam, East Nepal in 1972 (Map 1). TIBET Map 1. Route of Kyushu University Scientific Expe- dition to the Nepal Hima- laya in 1972. All the types of new species described in this paper are preserved in the Biological Laboratory, College of General Education, Kyushu University, Fuku- oka. We wish to thank to Professor Y. Hirashima and-Associate Professor K. Mori- moto of Kyushu University for their continuous guidance. Our thanks are due to Professor Emeritus T. ShirBzu and Professor T. Saigusa of Kyushu University for their help to the expedition; We also would like to thank Associate Professors A. Nakanishi and H. Shima of Kyushu University for their helpful suggestions.

D IAGNOSIS: This new species which is known by the female only is related to S. subu~ica~is (Gressitt) from Taiwan, but differs from it in the following points. S. emotoi sp. nov. : 8th antenna1 segment (excl. extreme base) white; middle part of prothorax closely punctured, dull; basal part of elytra with a narrow ill-defined longitudinal marking near suture; 3rd to 6th abdominal segments with black
