During the past few months sugar-canes in Trinidad have been attacked by a small insect of the group known as spittle insects or frog-hoppers. The name spittle insect is, given on account of the peculiarity of the inmiature insect in covering itself in a mass of white troth which is voided from the tip of the abdomen, and which forms a complete hiding-place or covering for the insect within. The name frog-hoppers was proltabl^' derived from the name of frog-spittle, formerly given to the frothy mass, and from the leaping habit of the adult. The frog-hoppers belong to the family Cercopidae, of the order Hemiptera, and are therefore related to the principal insect pests with sucking mouth-parts, such as scale insects, plant lice, plant bugs, cotton stainers, etc. Specimens of infested cane stumps and of the adult insect have been forwarded from Trinidad to the Head Office of the Imperial Department of Agriculture, and the following account is based on of these specimens. The adult insect is about ^^ inch in length, and about half as wide. The head and thorax are dark greenish, the wing-covers light-brown with two narrow whitish bands running across them. The head is stout and broad, the eyes prominent, and there are two small simple eyes on the upper surface of the head between the large compound eyes. The antennae are .short and hair-like, except the base, which is inueh thickened. The legs are dark-brown and slender ; the wing-covers are somewhat thickened, while the under wings are pale, tinged with smoky-brown, and with violaceous reflections. The immature specimens, so far examined, are all in the last larval stage of development. The bodies are whitish, tinged with pink or red, the head and thorax being darker. The developing wings are seen as dark, elongated pads lying on the basal part o
