ACROCERlDiE. 
J. 0. Westwood, Tr. E. Soc. 1876, describes the following new genera 
and species : — 
Apsona, p. 510. Near Panops and Lasia, but with a long bristle at 
the apex of the antennas, the proboscis of moderate length, and the 
2 posterior cellules pedicellated. A. muscaria, ibid., pi. v. fig. 2, New 
Zealand. 
Leucopsina, ibid. Near Panops, but with prominent thoracic shoulders 
and pedunculate abdomen. L. odyneroidcs, ibid., pi. v. fig. 3, Australia. 
Megalybus, p. 511. Next Philopota, with subquadrate thorax, which is 
dorsally more gibbous, and constricted abdominal segments. Also ap- 
proaches Systrojnis. M. pictiis, p. 511, pi. v. fig. 4, tristis, gracilis, fig. 5, 
and subcylindricus, p. 512, Chili. 
Pialeoidea, p. 514. Next Pialea, but with the antennae inserted near 
each other on a tubercle before and near the eyes, and the median 
longitudinal vein reaching the posterior margin. For Cyrtus magniis, 
Walker, pi. vi. fig. 3. 
Nothra, ibid. Neuration as in Pterodontia, but the costa not spurred,
