 In Denmark only 3 species are found, which live under the bark: of 

 infested deciduous and pinaceous trees, where they and their larvae pro- 

 bably feed on the young of the bast-borers. Many other species are found 

 in South Europe partly under stones and damp leaves; most of these are 

 wingless and with very short elytra.
