| - Biometric study on 285 male samples and 250 female samples from continental France, Corsica, Sardinia, Spain, Greece, Morocco and Algeria allows the following results: 1). Oedipoda miniata (Pallas), Oedipoda charpentieri (Fieber) and Oedipoda caerulescens (L.) form a group of species distinct from the other group consisted of Oedipoda germanica (Latreille) and Oedipoda fuscocincta (Lucas). At the species of the first group, the side keels of the metazona are complete, or almost, whereas at those of the second group they are null or reduced; the median keel of the prozona is quite projecting and narrow (with some exceptions at O. charpentieri and O. caerulescens of Corsica), whereas at the second group it is not very projecting, and it is broad at the base; the tegmina tend to being proportionally narrower at the first group, and the dark wing band extends less further in the anal field. - 2). In the Maghreb, Oedipoda miniata mauretanica Lucas has dimensions stronger than the European nominative subspecies; and especially the ratios length of the eyes / width of the vertex, and length of the eye / length of the subocular furrow, have lower values. So Oedipoda miniata mauretanica is perhaps a %22good%22 species; but it would be necessary to more study this question to be able to adopt such a conclusion definitively. - 3). Oedipoda caerulescens (L.) is represented in Corsica and Sardinia by a particular subspecies, vicarious of O. caerulescens caerulescens: Oedipoda caerulescens sardeti ssp. nov. ; at this taxon, the cubital prolongation of the dark wing band is less extended than at the nominative subspecies, above all in the males; in addition, the average values of the ratios length of the eyes / width of the vertex and length of the eyes / length of the subocular furrow are lower, and the posterior tarsi are red or brown red. It is not excluded that it is a %22good%22 species. - 4). In the Maghreb the specimens of Oedipoda caerulescens have the wings usually yellow or greenish yellow, exceptionally blue, whereas in Europe it is exactly the opposite; in addition the occiput is constantly strongly rugose in the Maghreb, while roughness is very variable in Europe. These elements make it possible to accept a under-specific statute for the Maghrebi taxon: Oedipoda caerulescens sulfurescens Saussure. - 5). Oedipoda miniata var. coerulea Saussure has been regarded for more than fifty years as a subspecies from Oedipoda fuscocincta Lucas (%22Oedipoda fuscocincta coerulea Saussure%22); but in this study it appears closer to Oedipoda germanica (Latreille): compared to O. fuscocincta, the metazona of the pronotum is shorter (proportionally with the prozona) at O. germanica and at O. coerulea, the tegmina are shortened (proportionally with the posterior femurs), and the ratio length of the eye / width of the vertex is lower. - 6). O. coerulea is distinguished clearly from O. germanica by the blue colouring of the wings (not red), and by the cubital prolongation of the wing band very much weaker. The strictly parapatric situation from these two taxa (the contact makes in the Pyrenees) allows to grant to O. coerulea a statute of %22good%22 species, vicarious of Oedipoda germanica (Latreille): Oedipoda (superpecies germanica) coerulea Saussure, stat. nov., comb. nov. - 7). What has been identified until now in Corsica and Sardinia as Oedipoda fuscocincta sicula or as O. %22fuscocincta%22 coerulea, according to the authors, is in reality a new taxon: Oedipoda fuscocincta morini ssp. nov., distinct from Oedipoda fuscocincta fuscocincta and Oedipoda fuuscocincta sicula by the greenish blue colouring of the posterior wings. After all, the following taxa may be found in France (including Corsica): Oedipoda charpentieri (Fieber), Oedipoda caerulescens caerulescens (Linnaeus), Oedipoda caerulescens sardeti ssp. nov., Oedipoda (germanica) germanica (Latreille), Oedipoda (germanica) coerulea Saussure and Oedipoda fuscocincta morini ssp. nov.
