FIG. 5. — Courbes de tendance linéaire de l'« indice Nc/D » (Nombre de cloisonnettes/Diamètre des loges) pour les populations de R. libur- nica (Stache, 1889) de la région type (Slovénie). Les courbes de tendance linéaire calculées sont complétées par les points extrêmes des mêmes populations et de quelques données accessibles par l'analyse de publications sur la même région. L'enveloppe de ces données constitue un polygone qui est reproduit sur les Figures 6 et 9 pour faciliter les comparaisons avec les autres populations étudiées.
