– TAXONOMIC NOTES ON SOME ITALIAN ODONATA — Enallagma cyathigerum possompesi from the Pyrenees is synonymized with E. c. cyathigerum, on the basis of Italian, Spanish and Turkish specimens. A discussion is given on the subspeciation of Ceriagrion tenellum and on the variability of some larval characters; the synonymy C. t. nielseni- C. t. tenellum is confirmed. Androchrome forms are recorded for $ Orthetrum coerulescens.
