The wing venation and articulation of B. geminata are described and illustrated. (433) COMPTE SART, A,, 1971. La filogenia en los Odonatos. (Phylogeny in the Odonata). Acta salmant., (I), 36 (Actas 1° Simp. int. Zoofilog., Salamanca, 1969); 329-332. (Spanish, with Engl. s.). – (Inst. Espan. Ent., Jose Gutierrez Abascal 2, Madrid-6, ES). The order is considered an old complex of living and extinct groups of frequently uncertain hierarchical level, whose intrinsic and adaptive characters are mixed. This and its considerable diversification along.various independent branches make a schematic phylogeny very difficult and suggest that the branches of the polyphyletic set be increased. Several larval and adult characters of phylogenetic interest as well as the odon. karyotypes are discussed and Meganisoptera are considered as the first true Odon. (Author).
