Should it eventually be considered not con- generic, I propose the name of Ceratopyga. The description of the species is as follows :— cJ. Head moderate, hardly broader than the thorax; vertex deeply bilobate, of shining metallic green. Eyes moderate, not contiguous, but very closely approximated, brown. Occiput metallic green, produced in two obtuse cones. Front very hairy, the hairs black and, together with the labium, of a reddish yellow. Thorax moderate, nearly square, slightly sloping in front, which part is hairy, the hairs brownish, of a dark brownish hue, with dark metallic green reflections, and a faint yellow line medially on each side; beneath reddish brown. Wings hyaline, somewhat pointed; neuration black, the reticulation wide, becoming finer towards hinder and apical margins; 17 antecubitals; hypertrigonal space 4-celled in upper wings, 3-celled in hind.

Pterostigma short, black, covering two and a half cellules. Membranule short, narrow, black. The legs are long, dull black, somewhat spiny ; the femora with a lateral carina outwardly and a row of small teeth in- wardly ; the tibiae have a lateral carina inwardly and a row of minute teeth outwardly. The tarsi are black, with long, deeply bifid, divaricate, curved claws. The body is long and narrow, cylindrical to the sixth segment, where it dilates to the eighth segment, the final segments decreasing gradually in width. Somewhat promi- nent rounded oreillettes occur on the second segment, and the. Please
