Observations on the Biology of Two Remarkable Cixiid Plant-Hoppers (Homoptera) From Cuba

Our knowledge of the biology of those families of Auehenorrhynehous Homoptera which reach their greatest development in the Tropics is scanty in the extreme. This is especially the ease with the Cixiidae, the intermediate stages of which are passed underground. There are not half a dozen species of these small but very interesting planthoppers of which the life-history is known. The two species considered here present highly remarkable features, the one, Mnemosyne cubana, for its association with Ponerine ants, and for peculiar features in its metamorphosis, and the other, Bothriocera signoreti from its fossorial habits and modified front legs in the nymph.
