New data on the distribution and taxonomy of some Palaearctic species of click-beetles of the subfamily Agrypninae are given. The external morphology and genitalia of the previously unknown females of Compsolacon korotjaevi Gur. and C. agrestis (Vats et Kash.) comb. n. are described. Several taxa are recorded from the following territories for the first time: the genus Eumoeus Cand. in the Palaearctic Region, the species Cornpsolacon agrestis comb. n. and C. himalayanus Jag. in Afghanistan, Compsolacon turkestanicus (Schw.) in Kyrgyzstan and Afghanistan, Danosoma conspersum (Gyll.) in Kazakhstan, Lacon quadrinodatus Lew. in Russia and L. unicolor (Cand.) in Iraq. Several North Indian species of Agrypnus Esch. are transferred to Compsolacon Rtt., and their systematic positions are briefly discussed: C. agrestis, C. inlustris (Vats et Kash.), C. jacksoni (Vats et Kash.), C. kuluensis (Vats et Kash.), C. maisus (Vats et Kash.), C. planocorpus (Vats et Kash.), C. rameshi (Vats et Kash.), C. repercussus (Vats et Kash.), C. solanensis (Vats et Kash.), C. souslapisus (Vats et Kash.), C. subargillus (Vats et Kash.), C. subfaenum (Vats et Kash.) and C. sublapideus (Vats et Kash.) (all comb. n.). The following new combinations are also proposed: Compsolacon aequalis (Cand.) comb. n. and Compsolacon brachychaetus (Kollar) comb. n. (both ex Lacon). The following new synonyms are established: Lacon funebris (Sols.) = Adelocera grisea Schw. syn. n. = Adelocera incompta Kr. syn. n.; Eumoeus murrayi Cand. = Tetralobus quadrifoveatus Vats et Kash. syn. n.
