The following table will give an idea of the relative distribution of the species as at present known :- Species. granosus cultratus cinereus obesns dealbatus cognatus opalinus impressicollis brevicollis bistrigicollis oneili granipennis planipennis lateralis tennicornis latipennis aciculatifrons barkeri scapularis griseus pnllus pollinosus marginatns spatulatus peringuey i viduus pondo tottus muricatus angustus panzanus schonlandi viridis nanus prasinus vittatus arrowi liorni wablbergi squamulosus Totals Cape. ft Natal. * ft ft Ik Pft * ft ft ft # ft * ft * ft ft 17 * * Hi * ft 20 Zululand.
