On the fauna of hemipteran bugs (Hemiptera: Auchenorrhyncha et Hetero- ptera) and big-headed flies (Diptera: Pipunculidae) of the Kaiserstuhl, southwestern Germany. - Field records of 157 Auchenorrhyncha species gathered on field excursions to five sites in the Kaiserstuhl Hill during the 9th Auchenorrhyncha Meeting, June 14th - 15th 2002, are presented. Particularly noteworthy was the first German record of the leafhopper Arocephalus sagittarius Rib., which was so far only known from southwestern Europe, and the very rare Edwardsiana smreczynskii Dwor., which is known only from less than 10 localities in Poland, Slowakia, Germany, Switzerland and France. Two further species, which are known in Germany only from this locality, notably Cixidia pilatoi D'Urso & Gugl. and Phlepsius intricatus (H.-S.), were no more found.
