In it 19 new species are described. Besides this, it gives a revised and enlarged keys to the Palaearctic species of the two genera, Lauxania and Lyciella.

Genus Homoneura van der Wulp, 1891.
a Among the Palaearctic genera, Homoneura is the most large group, containing about 70 species. The considerable part of them (approximately 50 species) occur in the east area of the Palaearctic Region. While preparing the review of the Palaearctic Homoneura for printing I had examined the compre- hensive material on this genus. As a result of this examination five new species from Russia and China are described. The Chinese material was collected in the last century by the famous geographer and ethnographer O.N.Potanin. Among the others his material contains two specimens, determined by L.Czerny as Homoneura grahami sMalIoch. The Fig. 1. Male pregenital sternites of Homoneura species: examination of these specimens has revealed that a - H.amurensis sp.n.; b - H.ozeroot sp.n. one of them should be reffered to a new species. PHC. 1.
