Length of the body 11 to 20 lines, oviduct 5 to 7 lines. Three examples, Charles Island; two examples, Albemarle Island, June 23rd. The type is from Charles Island ; it is the largest and most nearly adult example sent; the smaller examples are much paler. 4. ACRIDIUM MELANOCERUM. Acridium melanocerum, Stal, Eug. Resa, p. 326.

Olive-brown, depressed, densely punctured; head rounded and slightty narrowed in front, slightly notched in the middle of its anterior margin, angulated in front of the eyes, rounded behind, about as long as the thorax ; thorax deeply excavated in front, depressed at the sides; scutellum longer than the head and thorax together, linguiform ; corium of hemelytra extending beyond the end of tbe scutellum, the pellucid area being consequently extremely small; abdomen reddish brown, clouded with blackish ; legs rather slender, testaceous, all the femora with a black internal spot: length 4 lines. One imago, Charles Island (W. E. Cookson). There is also what I believe to be an immature form of this species ; but it is too little developed for accurate determination. 2. ANASA OBSCURA.
