Of the four moths dealt with in this paper, three are known to damage coconut palms in Celebes, and the fourth behaves similarly in the Gold Coast. Three of the species are here described as new. The opportunity has been taken to figure the larvae as well as the imagines of the Celebes species, and to include figures of Orthocraspeda catenatus, Snellen, of which two larvae and a pair of imagines were received with the other Celebes material. The short descriptions of the larvae are taken, with slight modifications, from Mr. A. Reyne's letter which accompanied the specimens. All the material concerned has been generously presented to the British Museum (Natural History) by the Director of the Imperial Institute of Entomology.
