Synopsis This book embodies the first reversionary work on subfamilies Selandn'inae and Dolerinae from India after Malaise (1944). To the previous knowledge, only 11 genera covering 20 species under these two subfamilies, 10 genera and 110 species (both new as well as the first record) have been added by the author and his co-workers. This contribution is an outcome of an extensive and intensive surveys of all high altitude regions, both along the entire Himalayan belt as well as South Indian hills, during the last 24 years. By providing elaborate identification keys both at generic and species level, detailed catalogue, illustrations and diagnostic features of all genera, this work not only compiles the hitherto scattered information regarding these two subfamilies, it also lays a very sound foundation for the future workers intending to work on different aspects of these insects.
