Previously unknown larvae of three species (Osmoderma davidis Fairmaire, Gnorimus subopacus Motschulsky, and Lasiotrichius succinctus (Pallas)) of the subfamily Trichiinae are described and illustrated. Original keys to larvae of the subfamilies Trichiinae, Cetoniinae, and Valgiinae and to the genera of the subfamily Trichiinae of the Russian fauna are compiled. The larva of Osmoderma davidis differs from that of O. barnabita Motschulsky in the shape of the frontal sutures and chaetotaxy of the frontal triangle and clypeus. The larvae of Gnorimus subopacus differ from those of G. nobilis (L.) and G. octopunctatus (F.) in the position of symmetrical rows of setae on the anal sternite. The larvae of representatives of the genus Lasiotrichius Reitter, described for the first time, differ from those of all the other genera of the subfamily Trichiinae in the smooth head capsule and in the absence of tubercles on the labrum. These larvae differ from those of the genus Trichius in the completely pale brown basal membrane at the antennae (the membrane of Trichius bears black stripe).
