The monograph herein is the second devoted to the Chrysomelidae, a family with more than 37,000 species described and probably much more still undescribed. The peculiar generalities of the group are reported and 13 species of subfamily Eumolpinae and 163 of subfamily Chrysomelinae are dealt with. The keys for the identification of these species are included, as well as the illustrative drawings, and geographic distributions for all of them. Moreover, in most of the cases biological data of interest are also indicated. At the end of this book, there is a very extensive appendix of scientific nomenclature. Also, a recent bibliography is given for complementing the first monography of ibero-balearic Chrysomelidae published in December 2000.
