These minute Insects are at present a source of considerable perplexity, owing to the curious nature of their metamorphosis, and the contradictory accounts given of them. In the earlier stages they are scale-like and qui- escent, being fixed to the under side of a leaf. The French authors Siguoret and Girard state that the young are hatched having visible ap- pendages and seg- mentation, but that after they are attached to the leaf the organs gradu- ally suffer atrophy.

Heeger states that the larva undergoes three ecdyses, and he gives the figures we reproduce ; if he be correct it would appear that the nymph undergoes a great development.
