On some Parasites and Hyperparasites of Artona catoxantha, Hamps

The Institute of Plant Diseases at Buitenzorg has been engaged in the study of the well-known coconut pest, Artona catoxantha, Hamps., and has sent to the Imperial Institute of Entomology a large and very interesting collection of its parasites and hyperparasites. We understand that Dr. J. v. d. Vecht is preparing a paper on the ecology of this Zygaenid. To complete his studies on the life-histories of all these parasites we have been asked to make a special study of the Chalcids.
